Description

The present invention relates to a suction device and a program.

Inhalation devices, such as electronic cigarettes and nebulizers, that generate a substance to be inhaled by a user are in widespread use. For example, an inhalation device generates an aerosol imparted with a flavor component using a substrate that includes an aerosol source for generating an aerosol and a flavor source for imparting a flavor component to the generated aerosol. A user can taste the flavor by inhaling the aerosol imparted with the flavor component generated by the inhalation device.

In recent years, technological developments have been made with the aim of further improving the quality of the user experience when using suction devices. For example, the following Patent Document 1 discloses a technology that does not heat the substrate when there is not enough remaining power in the suction device to consume one unused substrate.

<<1. Configuration example of suction device>>
The inhalation device is a device that generates a substance to be inhaled by a user. In the following description, the substance generated by the inhalation device is described as an aerosol. Alternatively, the substance generated by the inhalation device may be a gas.

(1) Example of Internal Configuration Fig. 1 is a schematic diagram showing an example of the internal configuration of a suction device. As shown in Fig. 1, a suction device 100 according to this example of configuration includes a power supply unit 111, a sensor unit 112, a notification unit 113, a storage unit 114, a communication unit 115, a control unit 116, a heating unit 121, a holding unit 140, and a heat insulating unit 144.

The power supply unit 111 stores power. The power supply unit 111 then supplies power to each component of the suction device 100 based on the control of the control unit 116. The power supply unit 111 may be configured, for example, by a rechargeable battery such as a lithium ion secondary battery.

The sensor unit 112 acquires various information related to the suction device 100. As one example, the sensor unit 112 is configured with a pressure sensor such as a microphone capacitor, a flow sensor, or a temperature sensor, and acquires values associated with suction by the user. As another example, the sensor unit 112 is configured with an input device that accepts information input from the user, such as a button or switch.

The notification unit 113 notifies the user of information. The notification unit 113 is composed of, for example, a light-emitting device that emits light, a display device that displays an image, a sound output device that outputs sound, or a vibration device that vibrates.

The memory unit 114 stores various information for the operation of the suction device 100. The memory unit 114 is configured, for example, by a non-volatile storage medium such as a flash memory.

The communication unit 115 is a communication interface capable of performing communication conforming to any wired or wireless communication standard. Such a communication standard may be, for example, Wi-Fi (registered trademark) or Bluetooth (registered trademark).

The control unit 116 functions as an arithmetic processing device and a control device, and controls the overall operation of the suction device 100 in accordance with various programs. The control unit 116 is realized by electronic circuits such as a CPU (Central Processing Unit) and a microprocessor.

The holding part 140 has an internal space 141, and holds the stick-shaped substrate 150 while accommodating a part of the stick-shaped substrate 150 in the internal space 141. The holding part 140 has an opening 142 that connects the internal space 141 to the outside, and holds the stick-shaped substrate 150 inserted into the internal space 141 from the opening 142. For example, the holding part 140 is a cylindrical body with the opening 142 and the bottom part 143 as the bottom surface, and defines a columnar internal space 141. The holding part 140 also has the function of defining a flow path for air to be supplied to the stick-shaped substrate 150. An air inlet hole, which is the entrance of air to such a flow path, is arranged in, for example, the bottom part 143. On the other hand, an air outlet hole, which is the exit of air from such a flow path, is the opening 142.

The stick-shaped substrate 150 includes a substrate portion 151 and a suction mouth portion 152. The substrate portion 151 includes an aerosol source. In this configuration example, the aerosol source is not limited to a liquid, but may be a solid. When the stick-shaped substrate 150 is held by the holding portion 140, at least a portion of the substrate portion 151 is contained in the internal space 141, and at least a portion of the suction mouth portion 152 protrudes from the opening 142. When the user holds the suction mouth portion 152 protruding from the opening 142 in his/her mouth and sucks, air flows into the internal space 141 from an air inlet hole (not shown) and reaches the user's mouth together with the aerosol generated from the substrate portion 151.

The heating unit 121 generates aerosol by heating the aerosol source and atomizing the aerosol source. In the example shown in FIG. 1, the heating unit 121 is configured in a film shape and arranged to cover the outer periphery of the holding unit 140. When the heating unit 121 generates heat, the substrate unit 151 of the stick-shaped substrate 150 is heated from the outer periphery, and an aerosol is generated. The heating unit 121 generates heat when power is supplied from the power supply unit 111. As an example, power may be supplied when the sensor unit 112 detects that the user has started inhaling and/or that specific information has been input. When the sensor unit 112 detects that the user has stopped inhaling and/or that specific information has been input, power supply may be stopped.

The insulating section 144 prevents heat transfer from the heating section 121 to other components. For example, the insulating section 144 is made of a vacuum insulating material or an aerogel insulating material.

The above describes an example configuration of the suction device 100. Of course, the configuration of the suction device 100 is not limited to the above, and various configurations such as those exemplified below may be used.

As one example, the heating unit 121 may be configured in a blade shape and arranged to protrude from the bottom 143 of the holding unit 140 into the internal space 141. In that case, the blade-shaped heating unit 121 is inserted into the substrate 151 of the stick-shaped substrate 150 and heats the substrate 151 of the stick-shaped substrate 150 from the inside. As another example, the heating unit 121 may be arranged to cover the bottom 143 of the holding unit 140. Furthermore, the heating unit 121 may be configured as a combination of two or more of a first heating unit covering the outer periphery of the holding unit 140, a blade-shaped second heating unit, and a third heating unit covering the bottom 143 of the holding unit 140.

As another example, the holding unit 140 may include an opening/closing mechanism such as a hinge that opens and closes a portion of the outer shell that forms the internal space 141. The holding unit 140 may then clamp the stick-shaped substrate 150 inserted into the internal space 141 by opening and closing the outer shell. In this case, the heating unit 121 may be provided at the clamping location in the holding unit 140, and may heat the stick-shaped substrate 150 while pressing it.

In addition, the means for atomizing the aerosol source is not limited to heating by the heating unit 121. For example, the means for atomizing the aerosol source may be induction heating.

(2) Exterior Configuration Example Fig. 2 is an overall perspective view of the suction device 100 according to this embodiment. Fig. 3 is an overall perspective view of the suction device according to this embodiment in a state in which a stick-type substrate 150 is held.

2 and 3, the inhalation device 100 has a top housing 11A, a bottom housing 11B, a cover 12, a switch 13, a lid portion 14, an air vent 15, and a cap 16. The top housing 11A and the bottom housing 11B are connected to each other to form the outermost outer housing 11 of the inhalation device 100. The outer housing 11 is sized to fit in the user's hand. When the user uses the inhalation device 100, the user can hold the inhalation device 100 in their hand and inhale the flavor.

The top housing 11A has an opening (not shown), and the cover 12 is coupled to the top housing 11A so as to close the opening. As shown in FIG. 3, the cover 12 has an opening 142 into which the stick-shaped substrate 150 can be inserted. The lid 14 is configured to open and close the opening 142 of the cover 12. Specifically, the lid 14 is attached to the cover 12 and configured to be movable along the surface of the cover 12 between a first position that closes the opening 142 and a second position that opens the opening 142. This allows the lid 14 to permit or restrict access of the stick-shaped substrate 150 to the inside of the suction device 100 (the internal space 141 shown in FIG. 1). The state in which the lid 14 is in the second position and the lid 14 opens the opening 142 is also referred to as an open state below. The state in which the lid 14 is in the first position and the lid 14 closes the opening 142 is also referred to as a closed state below.

The switch 13 is used to switch the operation of the inhalation device 100 on and off. For example, the user can operate the switch 13 while inserting the stick-type substrate 150 into the internal space 141 from the opening 142 as shown in FIG. 3, whereby power is supplied from the power supply unit 111 to the heating unit 121, and the stick-type substrate 150 can be heated without burning. When the stick-type substrate 150 is heated, an aerosol is generated from the aerosol source contained in the stick-type substrate 150, and the flavor of the flavor source is taken into the aerosol. The user can inhale the aerosol containing the flavor by inhaling the part of the stick-type substrate 150 protruding from the inhalation device 100 (the part shown in FIG. 3, i.e., the mouthpiece portion 152).

The vent 15 is a vent for introducing air into the internal space 141. The air taken into the inside of the suction device 100 from the vent 15 is introduced into the internal space 141 from an air inlet hole formed in the bottom 143 of the holding part 140, for example. The cap 16 is configured to be detachable from the bottom housing 11B. The cap 16 is attached to the bottom housing 11B to form the vent 15 between the bottom housing 11B and the cap 16. The cap 16 may have, for example, a through hole or a notch not shown. In this specification, the longitudinal direction of the suction device 100 refers to the direction in which the stick-shaped substrate 150 is inserted into the opening 142. In addition, in the suction device 100 of this specification, the side into which a fluid such as air flows in (for example, the vent 15 side) is the upstream side, and the side from which the fluid flows out (for example, the opening 142 side) is the downstream side.

＜＜2. Technical features＞＞

-Configuration of inhalation device 100 The configuration of inhalation device 100 is as described above. Hereinafter, the inhalation of the aerosol generated by the inhalation device 100 by the user will also be referred to simply as "inhalation" or "puffing." In addition, the action of the user inhaling will also be referred to hereinafter as a puffing action.

The inhalation device 100 according to this embodiment generates an aerosol to be inhaled by a user using a substrate containing an aerosol source. The heating unit 121 heats the substrate containing the aerosol source to generate an aerosol. The stick-shaped substrate 150 is an example of a substrate in this embodiment.

-Configuration of Terminal Device 200 The terminal device 200 is a device used by a user of the suction device 100. For example, the terminal device 200 is configured by any information processing device such as a smartphone, a tablet terminal, or a wearable device. As shown in Fig. 4, the terminal device 200 includes an input unit 210, an output unit 220, a communication unit 230, a storage unit 240, and a control unit 250.

The input unit 210 has a function of accepting input of various information. The input unit 210 may include an input device that accepts input of information from a user. Examples of the input device include a button, a keyboard, a touch panel, and a microphone. In addition, the input unit 210 may include various sensors such as an image sensor.

The output unit 220 has a function of outputting information. The output unit 220 may include an output device that outputs information to the user. Examples of the output device include a display device that displays information, a light-emitting device that emits light, a vibration device that vibrates, and a sound output device that outputs sound. An example of a display device is a display. An example of a light-emitting device is an LED (Light Emitting Diode). An example of a vibration device is an eccentric motor. An example of a sound output device is a speaker. The output unit 220 notifies the user of the information by outputting the information input from the control unit 250.

The communication unit 230 is a communication interface for transmitting and receiving information between the terminal device 200 and other devices. The communication unit 230 performs communication conforming to any wired or wireless communication standard. Such communication standards may include, for example, a wireless LAN (Local Area Network), a wired LAN, Wi-Fi (registered trademark), or Bluetooth (registered trademark).

The memory unit 240 stores various information for the operation of the terminal device 200. The memory unit 240 is configured, for example, by a non-volatile storage medium such as a flash memory.

The control unit 250 functions as a calculation processing device or control device, and controls the overall operation of the terminal device 200 according to various programs. The control unit 250 is realized by, for example, a CPU (Central Processing Unit) or an electronic circuit such as a microprocessor. In addition, the control unit 250 may include a ROM (Read Only Memory) that stores the programs and calculation parameters to be used, and a RAM (Random Access Memory) that temporarily stores parameters that change as appropriate. The terminal device 200 executes various processes based on the control of the control unit 250. The processing of information input by the input unit 210, the output of information by the output unit 220, the transmission and reception of information by the communication unit 230, and the storage and reading of information by the storage unit 240 are examples of processes controlled by the control unit 250. Other processes executed by the terminal device 200, such as the input of information to each component and processing based on information output from each component, are also controlled by the control unit 250.

The functions of the control unit 250 may be realized using an application. The application may be pre-installed or may be downloaded. The functions of the control unit 250 may be realized by PWA (Progressive Web Apps).

-Inter-Device Communication The suction device 100 is capable of communicating with other devices. The communication link used for communication between the suction device 100 and other devices may be wireless or wired. In this specification, the communication link will be described as being wireless.

In particular, the suction device 100 establishes a connection with another paired device and transmits and receives information. Pairing is a process in which two devices exchange and store information with each other. One example of the information exchanged is the other party's identification information, such as the SSID (Service Set Identifier), and information regarding the encryption key used to encrypt the information transmitted and received.

The suction device 100 and the terminal device 200 first perform pairing, and then transmit and receive information. It is preferable that the wireless communication standard used for wireless communication between the suction device 100 and the terminal device 200 is a short-range wireless communication standard such as Bluetooth. In that case, when the suction device 100 and the terminal device 200 are located within a range where short-range wireless communication is possible, they can establish a connection and communicate. In the following, it is assumed that the suction device 100 and the terminal device 200 communicate in accordance with BLE (Bluetooth Low Energy (registered trademark)).

A connection between the suction device 100 and the terminal device 200 may be established when a predetermined condition is satisfied. One example of a predetermined condition is that the state of the lid portion 14 has changed to an open state. Another example of a predetermined condition is that charging of the power supply unit 111 has started. When the suction device 100 is connected to an external power source, for example via a Universal Serial Bus (USB), the suction device 100 starts charging the power supply unit 111. When any of these predetermined conditions is satisfied, the suction device 100 starts transmitting an advertisement, establishes a connection with the terminal device 200 that has received the advertisement, and starts transmitting and receiving information.

The connection between the suction device 100 and the terminal device 200 may be disconnected when a predetermined condition is satisfied. One example of the predetermined condition is when the state of the lid portion 14 has changed to the closed state. Another example of the predetermined condition is when charging of the power supply unit 111 has finished. The suction device 100 finishes charging the power supply unit 111 when, for example, the connection to the external power source is released. The suction device 100 disconnects the connection with the terminal device 200 when, for example, any of these predetermined conditions is satisfied, no operation by the user is detected for a predetermined period of time or more, and no information is being transmitted or received.

(2) Setting Information The terminal device 200 can set the operation of the suction device 100. For example, the terminal device 200 displays a setting screen for setting the operation of the suction device 100. The setting screen displays the current settings of the suction device 100 and accepts input of information for changing the settings. The terminal device 200 generates setting information based on the information input by the user and transmits it to the suction device 100.

The setting information is information for making settings related to the operation of the suction device 100. The suction device 100 receives the setting information from the terminal device 200. The suction device 100 then makes settings based on the received setting information and operates according to the settings. Typically, the setting information is information for changing the settings of the suction device 100, and the suction device 100 changes the settings based on the received setting information. With this configuration, the user can make desired settings for the suction device 100 via the terminal device 200.

While transmitting the setting information, the terminal device 200 may display information indicating the progress of the transmission. For example, the terminal device 200 may display a progress bar in which the progress increases from 0 percent to 100 percent according to the amount of data already transmitted from the start to the completion of transmission of the setting information. With this configuration, the user can grasp the progress of the transmission of the setting information.

When the setting based on the setting information is completed, the suction device 100 transmits a setting completion notification to the terminal device 200 indicating that the setting has been completed. When the terminal device 200 receives the setting completion notification, the terminal device 200 may display a screen indicating that the setting of the suction device 100 has been completed. With this configuration, the user can know that the suction device 100 has completed the setting based on the setting information.

When the terminal device 200 receives a setting completion notification, it outputs information indicating the changed settings. For example, the terminal device 200 displays a screen indicating that the setting of the suction device 100 has been completed, and then displays a setting screen reflecting the changed settings. With this configuration, the user can grasp the changed settings.

(3) Setting the Communication Function The setting information may include information indicating whether or not to enable the communication function of the suction device 100. In other words, the setting information may include information indicating whether or not to permit communication by the communication unit 115. The suction device 100 enables or disables the communication function based on the received setting information. When the communication function is enabled, the communication unit 115 can communicate with the terminal device 200. When the communication function is disabled, the communication unit 115 does not communicate with the terminal device 200. With this configuration, the user can switch between enabling and disabling the communication function of the suction device 100.

When the communication function is disabled, the suction device 100 may enable the communication function when a predetermined condition is satisfied. One example of the predetermined condition is that an operation corresponding to a predetermined operation pattern has been performed. The operation pattern will be described in detail later. When the predetermined condition is satisfied, the suction device 100 starts transmitting an advertisement, establishes a connection with the terminal device 200 that received the advertisement, and starts transmitting and receiving information.

(4) Heating Profile The inhalation device 100 controls the operation of the heating unit 121 based on the heating profile. The heating profile is information indicating the time series transition of the target value of the parameter related to the operation of the heating unit 121. An example of the parameter is the temperature of the heating unit 121. In this case, the heating profile is information in which the time series transition of the target temperature, which is the target value of the temperature of the heating unit 121, is specified. The inhalation device 100 controls the temperature of the heating unit 121 so that the time series transition of the actual temperature (hereinafter also referred to as the actual temperature) of the heating unit 121 is similar to the time series transition of the target temperature specified in the heating profile. As a result, the aerosol is generated as planned by the heating profile. The heating profile is typically designed so that the flavor tasted by the user when the user inhales the aerosol generated from the stick-type substrate 150 is optimized. Therefore, by controlling the operation of the heating unit 121 based on the heating profile, the flavor tasted by the user can be optimized.

The control unit 116 controls the operation of the heating unit 121 based on the deviation between the target temperature specified in the heating profile and the actual temperature of the heating unit 121. More specifically, the control unit 116 controls the temperature of the heating unit 121 based on the deviation between the target temperature corresponding to the elapsed time since the control of the operation of the heating unit 121 based on the heating profile was started and the actual temperature. The temperature control of the heating unit 121 can be realized, for example, by known feedback control. Specifically, the control unit 116 supplies power from the power supply unit 111 to the heating unit 121 in the form of pulses by pulse width modulation (PWM) or pulse frequency modulation (PFM). In that case, the control unit 116 can control the temperature of the heating unit 121 by adjusting the duty ratio of the power pulse.

In feedback control, the control unit 116 may control the power supplied to the heating unit 121, for example the duty ratio described above, based on the difference between the actual temperature and the target temperature. The feedback control may be, for example, a proportional-integral-differential controller (PID) control. Alternatively, the control unit 116 may perform simple ON-OFF control. For example, the control unit 116 may perform heating by the heating unit 121 until the actual temperature reaches the target temperature, stop heating by the heating unit 121 when the actual temperature reaches the target temperature, and perform heating by the heating unit 121 again when the actual temperature becomes lower than the target temperature.

The temperature of the heating section 121 can be quantified, for example, by measuring or estimating the resistance value (more precisely, the electrical resistance value) of the heating section 121 (more precisely, the heating resistor that constitutes the heating section 121). This is because the resistance value of the heating resistor changes depending on the temperature. The resistance value of the heating resistor can be estimated, for example, by measuring the amount of voltage drop across the heating resistor. The amount of voltage drop across the heating resistor can be measured by a voltage sensor that measures the potential difference applied to the heating resistor. In another example, the temperature of the heating section 121 can be measured by a temperature sensor installed near the heating section 121.

As described above, when the resistance value of the heating unit 121 changes depending on the temperature of the heating unit 121, it can be said that the temperature of the heating unit 121 is synonymous with the resistance value of the heating unit 121. Therefore, the target temperature of the heating unit 121 can also be indicated by the resistance value of the heating unit 121. That is, another example of a parameter in the heating profile is the resistance value of the heating unit 121 corresponding to the target temperature. In that case, the heating profile is information in which the time series transition of the target resistance value, which is the target value of the resistance value of the heating unit 121, is specified. The suction device 100 controls the resistance value of the heating unit 121 so that the time series transition of the actual resistance value of the heating unit 121 is similar to the time series transition of the target resistance value specified in the heating profile. The control of the resistance value of the heating unit 121 can be realized, for example, by known feedback control. Specifically, the control unit 116 supplies power from the power supply unit 111 to the heating unit 121 in the form of pulses by pulse width modulation (PWM) or pulse frequency modulation (PFM). In this case, the control unit 116 can adjust the duty ratio of the power pulse to control the resistance value of the heating unit 121. With this configuration, it is possible to change the actual temperature of the heating unit 121 in the same way as in the case where the heating profile specifies the time series change of the target temperature.

Note that the temperature of the heating unit 121 corresponds to the resistance value of the heating unit 121, but the resistance value corresponding to the temperature of the heating unit 121 depends on the characteristics of the heating unit 121 and the environmental temperature. Therefore, if the characteristics or environmental temperature of the heating unit 121 are different, the target resistance value corresponding to the target temperature will be different even if the target temperature is the same.

The time period from the start to the end of the process of generating aerosol using the stick-shaped substrate 150, more specifically, the time period during which the heating unit 121 operates based on the heating profile, is also referred to as a heating session below. The start of a heating session is the timing when heating based on the heating profile starts. The end of a heating session is the timing when a sufficient amount of aerosol is no longer generated. A heating session consists of a pre-heating period in the first half and a puffable period in the second half. The puffable period is the period during which a sufficient amount of aerosol is expected to be generated. The pre-heating period is the period from the start of heating to the start of the puffable period. Heating performed in the pre-heating period is also referred to as pre-heating.

The heating session may include periods during which no power is supplied to the heating unit 121. As one example, the heating profile may include a section in which the temperature of the heating unit 121 is temporarily lowered, and power supply to the heating unit 121 may be stopped during such a section. As another example, power supply to the heating unit 121 may be stopped a predetermined time before the end of the puffable period, i.e., a predetermined time before the end of the heating session. Even during these periods during which no power is supplied to the heating unit 121, a sufficient amount of aerosol is generated by the residual heat of the heating unit 121 and the stick-shaped substrate 150.

The user may be notified of the start and end timing of the puffable period. Furthermore, the user may be notified of the timing a predetermined time before the end of the puffable period (for example, the timing when power supply to the heating unit 121 is stopped). In this case, the user can use the notification as a reference to puff during the puffable period.

It is anticipated that one or more puffs will be performed during a heating session, or more specifically, during a puffable period.

The inhalation device 100 may stop heating when the number of puffs performed by the user after heating of the stick-shaped substrate 150 has started reaches a predetermined upper limit. That is, the heating session may be interrupted when the number of puffs detected during the heating session (more specifically, during the puffable period) reaches a predetermined upper limit. The predetermined upper limit is set to a value corresponding to the number of puffs at which the aerosol source is assumed to be exhausted. With this configuration, even if a large number of puffs are performed and the aerosol source is exhausted early, heating based on the heating profile is continued, which makes it possible to prevent the occurrence of a situation in which an inferior flavor is delivered to the user.

The setting information may include information indicating a heating profile. In this case, the control unit 116 controls the operation of the heating unit 121 based on the heating profile indicated by the received information. With this configuration, the user can set a desired heating profile for the suction device 100.

The setting information may include information indicating a predetermined upper limit for the number of puffs during a heating session, as described above. In this case, the control unit 116 stops heating by the heating unit 121 when the number of puffs detected during the heating session reaches the upper limit indicated by the received information. With this configuration, the user can set a desired upper limit for the inhalation device 100.

(5) Operation Pattern The suction device 100 includes an operation unit that accepts physical operations by a user. The operation unit is an example of a sensor unit 112, and detects various operations performed by the user. A combination of operations on the operation unit is also referred to as an operation pattern below. The setting information may include information indicating the operation pattern. With this configuration, the user can set a desired operation pattern for the suction device 100.

The control unit 116 sets an operation pattern indicated by the received setting information, and controls the operation of the heating unit 121 according to the set operation pattern. As an example, the control unit 116 starts heating by the heating unit 121 when an operation corresponding to the set operation pattern is performed. A plurality of combinations of operation patterns and processes to be executed when an operation corresponding to the operation pattern is performed may be set. In that case, the control unit 116 executes a process that is combined with an operation pattern that corresponds to an operation performed on the suction device 100, out of the plurality of set operation patterns. With this configuration, the user can control the operation of the heating unit 121 according to a desired operation pattern.

The operation unit may include a button that accepts a pressing operation by the user. An example of such a button is the switch 13. In this case, the operation pattern includes an operation of pressing the switch 13. The operation of pressing the switch 13 may be classified into a short press in which the switch 13 is pressed and then released in a short time, and a long press in which the switch 13 is pressed and then released after a long time has elapsed. An example of an operation pattern is an operation of pressing the switch 13 twice shortly and then pressing it once long. The information indicating the operation pattern included in the setting information includes information indicating the time series transition of the state of the switch 13. The time series transition of the state of the switch 13 is the time series transition of whether the switch 13 is pressed or not pressed. Therefore, the number and timing (i.e., the order and interval) of short presses and long presses, as well as the time of long presses, etc. are set as an operation pattern by the setting information. According to this configuration, the user can set a desired operation pattern regarding the switch 13 to the suction device 100.

An example of an operation unit is the lid unit 14. In this case, the operation pattern includes an operation of opening and closing the opening 142 with the lid unit 14. An example of an operation pattern is an operation of opening and closing the opening 142 with the lid unit 14. The information indicating the operation pattern included in the setting information includes information indicating the time series transition of the state of the lid unit 14. The time series transition of the state of the lid unit 14 is the time series transition of whether the state of the lid unit 14 is in an open state or a closed state. Therefore, the number and timing (i.e., the order and interval) of the operation of opening the lid unit 14 and the operation of closing the lid unit 14 are set as the operation pattern by the setting information. With this configuration, the user can set a desired operation pattern related to the lid unit 14 to the suction device 100.

The operation pattern may be a combination of pressing the switch 13 and opening and closing the opening 142 with the lid 14. One example of an operation pattern is opening the opening 142 with the lid 14, then pressing the switch 13 twice briefly and then once for a long press. The information indicating the operation pattern included in the setting information includes information indicating the time series transition of the states of the switch 13 and the lid 14. With this configuration, the user can set a desired operation pattern related to the switch 13 and the lid 14 in the suction device 100.

(6) Lock Function The suction device 100 has a lock function. The lock function is a function for controlling whether or not heating is performed by the heating unit 121. Prohibition of heating by the heating unit 121 is also referred to as locking. Hereinafter, permission of heating by the heating unit 121 is also referred to as unlocking.

When the lock is released and a user operation is performed to instruct the start of heating, the suction device 100 starts heating using the heating unit 121. One example of an operation to instruct the start of heating is pressing the switch 13. On the other hand, when the lock is engaged and a user operation is performed to instruct the start of heating, the suction device 100 does not start heating using the heating unit 121. With this configuration, when the lock is engaged, heating using the heating unit 121 does not start even if the switch 13 is accidentally pressed, for example, inside a bag, so that the safety of using the suction device 100 can be improved.

- First lock function The operation pattern may be set in a first lock function that controls whether or not heating by the heating unit 121 is performed depending on an operation by a user. When the first lock function is enabled, the control unit 116 permits heating by the heating unit 121 when an operation corresponding to the operation pattern set in the first lock function is performed. On the other hand, when the first lock function is enabled, the control unit 116 prohibits heating by the heating unit 121 when an operation corresponding to the operation pattern set in the first lock function is not performed. The user can release the lock by the first lock function by performing an operation corresponding to the operation pattern set in the first lock function. When the lock is released, for example, when the switch 13 is pressed, heating by the heating unit 121 is started.

According to this configuration, the lock is not released unless an operation corresponding to the operation pattern set in the first lock function is performed. Therefore, it is possible to prevent misuse by persons other than the user, such as children, thereby improving the safety of using the suction device 100.

After the locking by the first locking function is released, the locking may be performed again if a predetermined condition is satisfied. One example of the predetermined condition is that the stick-shaped substrate 150 is pulled out and the state of the lid portion 14 changes to the closed state after heating by the heating portion 121 is terminated. Another example of the predetermined condition is that an operation corresponding to the operation pattern set in the first locking function is performed again.

The setting information may include information indicating whether or not to enable the first lock function. In that case, the control unit 116 sets the first lock function to be enabled or disabled based on the setting information. For example, if the setting information includes information indicating that the first lock function is enabled, the control unit 116 enables the first lock function. In that case, the lock is not released unless an operation corresponding to the operation pattern set in the first lock function is performed. On the other hand, if the setting information includes information indicating that the first lock function is disabled, the control unit 116 disables the first lock function. In that case, since the first lock function does not lock the device, the user can start heating by the heating unit 121 simply by pressing the switch 13.

According to this configuration, safety can be improved by enabling the first lock function only when the user is at home, where misuse by children is expected. On the other hand, when the user is at work, where misuse by children is not expected, the first lock function can be disabled, reducing the effort required to perform unlocking operations and improving usability.

- Second lock function The communication state of the communication unit 115 may be used for a second lock function that controls whether or not heating by the heating unit 121 is performed depending on the communication state of the communication unit 115. When the second lock function is enabled, the control unit 116 permits heating by the heating unit 121 when the communication unit 115 is communicating with the terminal device 200. On the other hand, when the second lock function is enabled, the control unit 116 prohibits heating by the heating unit 121 when the communication unit 115 is not communicating with the terminal device 200. Here, an example of the communication unit 115 communicating with the terminal device 200 is that a connection based on a short-range wireless communication standard such as Bluetooth is established between the suction device 100 and the terminal device 200. The user can release the lock by the second lock function by establishing a connection based on a short-range wireless communication standard between the suction device 100 and the terminal device 200. When the lock is released and, for example, the switch 13 is pressed, heating by the heating unit 121 is started.

According to this configuration, the lock is released only when the suction device 100 and the terminal device 200 are located within a range where short-distance wireless communication is possible and are communicating, and the lock is not released otherwise. Therefore, when a user goes out carrying the terminal device 200, it is possible to prevent the suction device 100 left at home from being misused by, for example, a child. This makes it possible to improve the safety of using the suction device 100. On the other hand, when a user uses the suction device 100 while carrying the terminal device 200, the lock is automatically released, which reduces the effort required to perform an unlocking operation and improves usability.

The setting information may include information indicating whether or not to enable the second lock function. In that case, the control unit 116 sets the second lock function to be enabled or disabled based on the setting information. For example, if the setting information includes information indicating that the second lock function is enabled, the control unit 116 enables the second lock function. In that case, the lock is not released unless communication is performed between the suction device 100 and the terminal device 200. On the other hand, if the setting information includes information indicating that the second lock function is disabled, the control unit 116 disables the second lock function. In that case, since the lock is not applied by the second lock function, the user can start heating by the heating unit 121 simply by pressing the switch 13, regardless of whether communication is performed between the suction device 100 and the terminal device 200.

With this configuration, the second lock function can be switched between enabled and disabled at will, thereby improving usability.

-Third lock function The state of the lid part 14 is used for the third lock function that controls whether or not heating by the heating part 121 is performed depending on the state of the lid part 14. When the third lock function is enabled, the control part 116 permits heating by the heating part 121 when the lid part 14 is in the open state. On the other hand, when the third lock function is enabled, the control part 116 prohibits heating by the heating part 121 when the lid part 14 is in the closed state. When the lid part 14 is in the closed state, at least the stick-type substrate 150 is not inserted in the suction device 100. Therefore, when heating is performed when the lid part 14 is in the closed state, heating occurs even though the stick-type substrate 150 is not inserted, which is called empty heating. In this regard, the third lock function makes it possible to prevent empty heating.

From the viewpoint of preventing dry-burning, it is desirable that the third lock function be always enabled. Of course, information indicating whether or not to enable the third lock function may be included in the setting information, and whether or not to enable the third lock function may be switched based on such setting information.

-Combined Use of Multiple Lock Functions Multiple lock functions may be used in combination. For example, the first lock function, the second lock function, and the third lock function described above may be used in combination.

The conditions for unlocking the first lock function and the second lock function may constitute an OR condition (i.e., a logical sum). That is, the lock may be released when either the condition for unlocking the first lock function or the condition for unlocking the second lock function is satisfied. And, the lock may not be released when neither the condition for unlocking the first lock function or the condition for unlocking the second lock function is satisfied. Specifically, when the first lock function and the second lock function are enabled, the control unit 116 permits heating by the heating unit 121 when an operation corresponding to the operation pattern set in the first lock function is performed or when the communication unit 115 is communicating with the terminal device 200. On the other hand, the control unit 116 prohibits heating by the heating unit 121 when an operation corresponding to the operation pattern set in the first lock function is not performed and the communication unit 115 is not communicating with the terminal device 200. According to this configuration, the lock can be released by either the first lock function or the second lock function, so that usability can be improved.

Furthermore, the above-mentioned OR conditions related to the first lock function and the second lock function, and the condition for unlocking defined in the third lock function may constitute an AND condition (i.e., logical product). That is, the lock may be released when the condition for unlocking defined in the third lock function is satisfied and either the condition for unlocking defined in the first lock function or the second lock function is satisfied. And, the lock may not be released when the condition for unlocking defined in the third lock function is not satisfied, or when neither the condition for unlocking defined in the first lock function nor the second lock function is satisfied. Specifically, when the first lock function, the second lock function, and the third lock function are enabled, the control unit 116 permits heating by the heating unit 121 when the state of the cover unit 14 is in the open state and an operation corresponding to the operation pattern set in the first lock function is performed, or when the communication unit 115 is communicating with the terminal device 200. On the other hand, the control unit 116 prohibits heating by the heating unit 121 when the lid unit 14 is in the closed state, or when an operation corresponding to the operation pattern set in the first lock function has not been performed, and the communication unit 115 is not communicating with the terminal device 200. With this configuration, it is possible to release the lock using either the first lock function or the second lock function while preventing dry-burning, so that it is possible to ensure safety and improve usability at the same time.

(7) Battery Information The suction device 100 transmits battery information, which is information indicating the state of the power supply unit 111 that accumulates and supplies power for the operation of the suction device 100. With this configuration, the terminal device 200 can grasp the state of the power supply unit 111 based on the battery information.

The battery information may include information indicating the remaining power of the power supply unit 111. As an example, the information indicating the remaining power of the power supply unit 111 is information indicating the percentage of the remaining power based on the maximum value of the power that can be stored in the power supply unit 111. With this configuration, the terminal device 200 is able to grasp the decrease in the remaining power and prompt the user to charge the power supply unit 111.

The battery information may include information indicating the deterioration of the power supply unit 111. As an example, whether the power supply unit 111 has deteriorated may be determined by SOH (State of Health). In that case, the control unit 116 determines that the power supply unit 111 has deteriorated when the ratio of the current full charge capacity to the initial full charge capacity of 100% falls below a predetermined threshold. As another example, whether the power supply unit 111 has deteriorated may be determined by cycle count. In that case, the control unit 116 counts one cycle each time the cumulative value of the charging current reaches the full charge capacity, and determines that the power supply unit 111 has deteriorated when the count exceeds a predetermined threshold. Then, when it is determined that the power supply unit 111 has deteriorated, battery information including information indicating the deterioration of the power supply unit 111 is transmitted. According to this configuration, the terminal device 200 is able to grasp the deterioration of the power supply unit 111 and urge the user to take measures against the deterioration of the power supply unit 111.

The battery information may be transmitted when a connection between the suction device 100 and the terminal device 200 is established. As an example, a connection may be established and the battery information may be transmitted when, for example, the state of the lid portion 14 is changed from a closed state to an open state before heating by the heating portion 121 is started. With such a configuration, it is possible to notify the user of the state of the power supply portion 111 before heating the stick-shaped substrate 150. As another example, a connection may be established and the battery information may be transmitted when charging of the power supply portion 111 is started. With such a configuration, it is possible to notify the user of the state of the power supply portion 111 before charging.

The battery information may be transmitted before the connection between the suction device 100 and the terminal device 200 is disconnected. As an example, the battery information may be transmitted after heating by the heating unit 121 has ended, for example when the state of the lid unit 14 has changed from an open state to a closed state. With this configuration, it is possible to notify the user of the state of the power supply unit 111 after the stick-shaped substrate 150 has been heated. As another example, the battery information may be transmitted when charging of the power supply unit 111 has ended. With this configuration, it is possible to notify the user of the state of the power supply unit 111 after charging.

The suction device 100 may notify the user of the battery information via the notification unit 113. With this configuration, the suction device 100 alone can notify the user of the state of the power supply unit 111.

(8) Log Information The suction device 100 stores log information in the memory unit 114. The log information is information acquired in response to the use of the suction device 100 by a user and stored in the memory unit 114. The suction device 100 transmits the log information stored in the memory unit 114 to the terminal device 200. It is assumed that the suction device 100 and the terminal device 200 are not always connected to each other. Therefore, the suction device 100 accumulates log information while not connected to the terminal device 200, and transmits the accumulated log information when the suction device 100 is connected to the terminal device 200.

The terminal device 200 transfers the log information received from the suction device 100 to another device. An example of the other device is a server that provides services related to the suction device 100. The server collects and analyzes the log information and uses it for services such as updating the firmware of the suction device 100.

- Information Acquired During a Heating Session The log information may include information acquired during a heating session, i.e., in one heating session. When heating is performed by the heating unit 121, the storage unit 114 stores the information acquired during the heating session as log information. With this configuration, it is possible to grasp the situation during the heating session later.

The information acquired during the heating session may include information for identifying the heating session. One example of information for identifying the heating session is inhalation start time information indicating the time when the first puff was performed in the heating session, i.e., the time when the first puff was performed after heating was started. With this configuration, it becomes possible to later determine the interval between heating sessions and the number of heating sessions per day.

The information acquired during the heating session may include information indicating a factor that permitted heating by the heating unit 121. The information indicating a factor that permitted heating includes any one of information indicating that heating was permitted by the first lock function, information indicating that heating was permitted by the second lock function, or information indicating that the first lock function and the second lock function were disabled. When the first lock function is enabled and an operation corresponding to the operation pattern set in the first lock function is performed to release the lock and perform heating, the information indicating a factor that permitted heating includes information indicating that heating was permitted by the first lock function. When the second lock function is enabled and the lock is released and heating is performed based on the communication between the suction device 100 and the terminal device 200, the information indicating a factor that permitted heating includes information indicating that heating was permitted by the second lock function. When heating is performed with both the first lock function and the second lock function disabled, the information indicating a factor that permitted heating includes information indicating that the first lock function and the second lock function were disabled. With this configuration, analysis of the use of the first lock function and the second lock function is possible.

The information acquired during the heating session may include the duration of the heating session. With this configuration, it is possible to know the duration of the heating session later.

The information acquired during the heating session may include information indicating the number of puffs performed during the heating session. With this configuration, it is possible to know later the number of puffs performed during the heating session.

The information acquired during the heating session may include information indicating the time at which a puff was performed during the heating session. Multiple puffs may be performed during the heating session, in which case the information acquired during the heating session includes information indicating the time at which each of the one or more puffs performed during the heating session was performed. With this configuration, it is possible to later determine the timing of the puffs performed during the heating session.

The information acquired during the heating session may include information indicating the deterioration state of the power supply unit 111 during the heating session. The information indicating the deterioration state of the power supply unit 111 may be, for example, the percentage of the current full charge capacity when the initial full charge capacity is set to 100%, or the number of times the cumulative value of the charging current has reached the full charge capacity. With this configuration, it is possible to grasp the progress of the deterioration state later.

- Information Indicating Operation History The log information may include information indicating the operation history of the suction device 100. With this configuration, it becomes possible to later grasp the history of operations that have been performed by the suction device 100.

The information indicating the operation history may include the cumulative time that the heating unit 121 has performed heating since the suction device 100 was initially started. With this configuration, it is possible to grasp the length of time that the heating unit 121 has performed heating throughout the entire life cycle of the suction device 100.

The information indicating the operation history may include the time that has elapsed since the suction device 100 was first started. With this configuration, it is possible to grasp the entire life cycle of the suction device 100.

The information indicating the operation history may include the cumulative number of times that the heating unit 121 has performed heating since the suction device 100 was first started. With this configuration, it is possible to grasp the number of times heating has been performed throughout the entire life cycle of the suction device 100.

The information indicating the operation history may include a history of errors that have occurred since the suction device 100 was first started. With this configuration, it is possible to grasp errors that have occurred throughout the entire life cycle of the suction device 100.

- Information indicating remaining power The log information may include information indicating the remaining power of the power supply unit 111. The storage unit 114 stores, as log information, information indicating the remaining power from among the battery information acquired for transmission to the terminal device 200. With this configuration, it becomes possible to grasp the transition of the remaining power of the power supply unit 111 at a later time.

- Information Acquired During Charging The log information may include information acquired during charging of the power supply unit 111. When charging of the power supply unit 111 is performed, the storage unit 114 stores the information acquired during charging of the power supply unit 111 as log information.

One example of information acquired during charging is information indicating the time charging started, and information indicating the remaining power at the time charging started. Another example of information acquired during charging is information indicating the time charging ended, and information indicating the remaining power at the time charging ended. With this configuration, it is possible to grasp the charging history by the user.

Timing of Transmission of Log Information The timing at which the suction device 100 transmits the log information may be controlled by the terminal device 200. In detail, the terminal device 200 transmits a log request to the suction device 100, which requests the suction device 100 to perform processing for transmitting the log information. The suction device 100 performs the processing requested in the received log request. For example, the terminal device 200 transmits a log request to the suction device 100, which requests the suction device 100 to transmit log information, and the suction device 100 that receives the log request transmits the log information. With this configuration, the suction device 100 can transmit log information at an appropriate timing under the control of the terminal device 200.

(9) Status Information The suction device 100 transmits status information indicating the status of the suction device 100 to the terminal device 200. According to this configuration, the terminal device 200 can grasp the status of the suction device 100 in real time based on the received status information.

- Information Indicating the Status of Heating Unit 121 The status information may include information indicating the status of heating unit 121. In particular, the status information may include information indicating the progress of heating by heating unit 121. During a heating session, suction device 100 transmits status information indicating the progress of heating by heating unit 121. With this configuration, terminal device 200 can grasp the status of heating unit 121 during a heating session in real time based on the status information.

As an example, the status information may include information indicating that heating by the heating unit 121 has started. The suction device 100 transmits such status information at the timing when heating based on the heating profile has started.

As another example, the status information may include information indicating that pre-heating has ended, i.e., that the puffable period has begun. The inhalation device 100 transmits such status information, for example, when a predetermined time has elapsed since the start of heating based on the heating profile.

As another example, the status information may include information indicating that a timing is a predetermined time before the end of the puffable period. The inhalation device 100 transmits such status information, for example, when the supply of power to the heating unit 121 ends.

As another example, the status information may include information indicating that the puffing period has ended. The inhalation device 100 transmits such status information, for example, when a predetermined time has elapsed since the supply of power to the heating unit 121 ended.

- Information indicating the state of the lid portion 14 The state information may include information indicating the state of the lid portion 14. As an example, the state information may include information indicating that the state of the lid portion 14 is an open state or a closed state. When the state of the lid portion 14 changes, the suction device 100 transmits state information indicating the state of the lid portion 14 after the change. With this configuration, the terminal device 200 can grasp the state of the lid portion 14 in real time based on the state information.

- Information indicating the charging state of power supply unit 111 The status information may include information indicating the charging state of power supply unit 111. As an example, the status information may include information indicating the ratio of the current charging amount to the full charge capacity of power supply unit 111. During charging, suction device 100 may transmit status information including information indicating the charging state of power supply unit 111. With this configuration, terminal device 200 can grasp the charging state of power supply unit 111 in real time based on the status information.

(10) Connection Control According to Remaining Power The suction device 100 compares the remaining power of the power supply unit 111 with a threshold, and controls whether or not to execute a procedure for establishing a connection between the suction device 100 and another device (i.e., the terminal device 200) based on the comparison result. With this configuration, whether or not to establish a connection between the suction device 100 and the terminal device 200 is switched depending on the remaining power of the suction device 100. Therefore, the suction device 100 can perform communication appropriate to the remaining power. In the following, the threshold is also referred to as a connection threshold, and the procedure is also referred to as a connection procedure.

Specifically, the suction device 100 executes the connection procedure when the remaining power of the power supply unit 111 is equal to or greater than the connection threshold, and does not execute the connection procedure when the remaining power of the power supply unit 111 is less than the connection threshold. That is, the suction device 100 executes the connection procedure only when it has sufficient remaining power equal to or greater than the connection threshold. With this configuration, it is possible to avoid a situation in which the connection procedure is executed even when there is insufficient remaining power, resulting in insufficient remaining power.

The connection procedure includes transmitting and receiving a signal to establish a connection. More specifically, the connection procedure executed by the suction device 100 includes transmitting a signal that triggers the start of the connection procedure. One example of a signal that triggers the start of the connection procedure is an advertisement. The connection procedure executed by the suction device 100 also includes, after transmitting the advertisement, waiting to receive a signal transmitted from the terminal device 200 that received the advertisement. During the period in which the suction device 100 is waiting to receive, the suction device 100 establishes a connection with the terminal device 200 by receiving a connection request, which is a signal requesting a connection, from the terminal device 200.

The connection procedure may include pairing. If pairing between the suction device 100 and the terminal device 200 has not yet been completed, a connection is established via pairing. In this case, the connection procedure includes at least exchanging an encryption key between the suction device 100 and the terminal device 200, which is used to encrypt information transmitted and received between the suction device 100 and the terminal device 200. With this configuration, if pairing between the suction device 100 and the terminal device 200 has not yet been completed, it is possible to control whether or not to execute the connection procedure, taking into account the amount of power required for pairing.

The connection procedure may be executed when the lid 14 opens the opening 142, i.e., when the state of the lid 14 changes to the open state. Therefore, the suction device 100 may control whether or not to execute the connection procedure when the lid 14 opens the opening 142. That is, the suction device 100 may compare the remaining power of the power supply unit 111 with the connection threshold when the lid 14 opens the opening 142, and control whether or not to execute the connection procedure based on the comparison result when the suction device 100 controls whether or not to execute the connection procedure when the lid 14 opens the opening 142. The stick-shaped substrate 150 is heated with the lid 14 opening the opening 142. In this regard, with this configuration, it is possible to control whether or not to execute the connection procedure in anticipation of the amount of power to be used for heating the stick-shaped substrate 150 that will be executed in the future.

- Setting of connection threshold The connection threshold is a value equal to or greater than the amount of power used for the heating unit 121 to execute the process of heating the stick-type substrate 150 to generate an aerosol a specified number of times. The process of heating the stick-type substrate 150 to generate an aerosol is executed once for each stick-type substrate 150, and the specified number of times corresponds to the number of stick-type substrates 150 consumed. Consumption here refers to executing heating of the stick-type substrate 150 based on the heating profile from start to finish without interruption. That is, the connection threshold is a value equal to or greater than the amount of power used to consume a specified number of stick-type substrates 150. According to this configuration, the connection procedure is executed only when the power supply unit 111 has a remaining power amount equal to or greater than the amount of power used to consume a specified number of stick-type substrates 150. Therefore, it is possible to avoid a situation in which the specified number of stick-type substrates 150 cannot be consumed due to insufficient remaining power even after the connection procedure has been executed.

The specified number of times may be 1. In that case, the suction device 100 executes the connection procedure only when it has the remaining power to consume one stick-type substrate 150. This configuration makes it possible to avoid a situation in which, even though the connection procedure has been executed, it is not possible to consume even one stick-type substrate 150.

The suction device 100 according to this embodiment executes a connection procedure before starting to heat the stick-shaped substrate 150. This is because communication with the terminal device 200 is performed during or before and after heating the stick-shaped substrate 150. For this reason, it is desirable that the power used for these communications be taken into account in the connection threshold.

Therefore, it is desirable that the connection threshold be a value equal to or greater than the sum of the amount of power used by the heating unit 121 to execute the process of heating the stick-shaped substrate 150 to generate an aerosol a specified number of times and the amount of power used to execute the connection procedure. The amount of power used to execute the connection procedure here is, for example, the amount of power used to send an advertisement and wait for a connection request to be received. With this configuration, the connection procedure is executed only when the power supply unit 111 has a remaining power amount equal to or greater than the connection threshold, taking into account the amount of power used to execute the connection procedure. This makes it possible to avoid a situation in which the remaining power amount becomes insufficient due to the execution of the connection procedure, making it impossible to consume the specified number of stick-shaped substrates 150.

Furthermore, it is desirable that the connection threshold is equal to or greater than the sum of the amount of power used by the heating unit 121 to heat the stick-shaped substrate 150 and generate an aerosol a specified number of times, the amount of power used to execute the connection procedure, and the amount of power used for communication between the suction device 100 and the terminal device 200 that is performed when the heating unit 121 heats the stick-shaped substrate 150 and generates an aerosol a specified number of times. As will be described in detail later, various communications may be performed when the specified number of stick-shaped substrates 150 are consumed. In this regard, according to this configuration, the connection procedure is performed only when the power supply unit 111 has a remaining power amount equal to or greater than the connection threshold, taking into account the amount of power used for communication that is performed when the specified number of stick-shaped substrates 150 are consumed. Therefore, it is possible to avoid a situation in which the remaining power amount becomes insufficient due to the execution of the connection procedure, and the consumption of the specified number of stick-shaped substrates 150 or the communication associated therewith cannot be performed.

An example of communication that accompanies the consumption of a specified number of stick-shaped substrates 150 is the suction device 100 transmitting battery information. As an example, the suction device 100 may establish a connection with the terminal device 200 and transmit battery information at the timing when, for example, the state of the lid part 14 changes from a closed state to an open state before heating by the heating part 121 is started. As another example, the suction device 100 may transmit battery information at the timing when, for example, the state of the lid part 14 changes from an open state to a closed state after heating by the heating part 121 is finished. Therefore, the connection threshold may be set taking into account the amount of power used for transmitting the battery information. With this configuration, it is possible to avoid a situation in which the remaining power becomes insufficient due to the execution of a connection procedure, and consumption of the specified number of stick-shaped substrates 150 or transmission of the associated battery information cannot be executed.

An example of communication that occurs when a specified number of stick-shaped substrates 150 are consumed is when the suction device 100 transmits status information indicating the status of the heating unit 121. As an example, the suction device 100 may transmit status information indicating the progress of heating by the heating unit 121 during a heating session. Thus, the connection threshold may be set taking into account the amount of power used for transmitting the status information. With this configuration, it is possible to avoid a situation in which the remaining power becomes insufficient due to the execution of a connection procedure, making it impossible to consume the specified number of stick-shaped substrates 150 or transmit the associated status information.

An example of communication accompanying the consumption of a specified number of stick-type substrates 150 is the transmission of log information acquired when the suction device 100 executes a process for heating the stick-type substrates 150 to generate an aerosol. As an example, the suction device 100 may transmit log information acquired during a heating session after the heating session ends. Thus, the connection threshold may be set taking into account the amount of power used to transmit the log information. With this configuration, it is possible to avoid a situation in which the remaining power becomes insufficient due to the execution of a connection procedure, making it impossible to consume the specified number of stick-type substrates 150 or transmit the associated log information.

The suction device 100 may identify the stick-type substrate 150 to be heated. The stick-type substrate 150 to be heated is the stick-type substrate 150 inserted into the suction device 100. For example, identification information such as a two-dimensional code for identifying the stick-type substrate 150 may be attached to the stick-type substrate 150. In that case, the suction device 100 identifies the stick-type substrate 150 by reading the identification information attached to the inserted stick-type substrate 150. The suction device 100 may then set a connection threshold according to the identification result of the stick-type substrate 150. The manner of temperature change differs for each stick-type substrate 150, and the amount of power used to consume one stick-type substrate 150 may differ. In this regard, according to this configuration, it is possible to appropriately control whether or not to execute the connection procedure according to the stick-type substrate 150.

As described above, the suction device 100 operates the heating unit 121 based on the heating profile. The suction device 100 may switch the heating profile to be used. For example, the suction device 100 switches the heating profile to be used in response to a user operation or in response to the stick-type substrate 150 to be used. In this case, the suction device 100 may set a connection threshold in response to the heating profile to be used. The target temperature and time length differ for each heating profile, and the amount of power used to consume one stick-type substrate 150 may differ. In this regard, with such a configuration, it becomes possible to appropriately control whether or not to execute the connection procedure in response to the heating profile.

Processing when remaining power is less than the connection threshold When the remaining power of the power supply unit 111 is less than the connection threshold, the suction device 100 does not execute the connection procedure. However, when the remaining power of the power supply unit 111 is less than the connection threshold, the suction device 100 may perform other control.

Another example of control is not to heat the stick-shaped substrate 150. If the remaining power of the power supply unit 111 is less than the connection threshold, even if heating of the stick-shaped substrate 150 is performed, heating may be interrupted midway through the heating profile due to insufficient remaining power. In this regard, with this configuration, it is possible to avoid a situation in which the stick-shaped substrate 150 is partially consumed due to insufficient remaining power.

Another example of control is to heat the stick-shaped substrate 150. For example, it is assumed that the remaining power of the power supply unit 111 is less than the connection threshold, but is equal to or greater than the amount of power used by the heating unit 121 to heat the stick-shaped substrate 150 and generate an aerosol a specified number of times. In such a case, by omitting communication with the terminal device 200 and saving power consumption, it is possible for the heating unit 121 to heat the stick-shaped substrate 150 and generate an aerosol a specified number of times. With this configuration, it is possible to provide an aerosol to a user while omitting the provision of services associated with communication between the suction device 100 and the terminal device 200.

Another example of control is to notify the user of information indicating that the remaining power of the power supply unit 111 is less than the connection threshold. The suction device 100 notifies the user of such information via the notification unit 113.

5 is a sequence diagram showing an example of an overall process flow for a heating session executed in the system 1 according to this embodiment. This sequence involves the suction device 100 and the terminal device 200.

As shown in FIG. 5, first, the suction device 100 accepts an operation to set the lid portion 14 to an open state (step S102).

Next, the suction device 100 and the terminal device 200 establish a connection (step S104). For example, the suction device 100 transmits an advertisement, and the suction device 100 and the terminal device 200 that receives the advertisement perform a procedure to establish a connection.

Next, the suction device 100 transmits the battery information to the terminal device 200 (step S106).

Next, the suction device 100 releases the lock (step S108). For example, the suction device 100 releases the lock based on the fact that the state of the lid portion 14 is in the open state and that the suction device 100 is communicating with the terminal device 200 regarding the second lock function.

Next, the suction device 100 receives an operation to start heating (step S110).

Next, the suction device 100 starts heating based on the heating profile (step S112).

Next, the suction device 100 transmits status information including information indicating the status of the heating unit 121 to the terminal device 200 (step S114).

Next, the suction device 100 determines whether the heating session has ended (step S116). For example, the suction device 100 determines that the heating session has ended when the time elapsed since the start of heating based on the heating profile exceeds a predetermined threshold. Alternatively, the suction device 100 determines that the heating session has ended when the number of puffs performed during the heating session reaches a predetermined upper limit. If it is determined that the heating session has not ended (step S116: NO), the process returns to step S114 again.

If it is determined that the heating session has ended (step S116: YES), the suction device 100 determines whether or not an operation to close the lid portion 14 has been performed (step S118). If it is determined that an operation to close the lid portion 14 has not been performed (step S118: NO), the suction device 100 waits until an operation to close the lid portion 14 is performed.

If it is determined that an operation has been performed to change the state of the lid portion 14 to a closed state (step S118: YES), the suction device 100 transmits status information including information indicating that the state of the lid portion 14 has changed to a closed state, and battery information to the terminal device 200 (step S120).

Next, the terminal device 200 transmits the setting information to the suction device 100 (step S122). Next, when the suction device 100 receives the setting information, it performs settings based on the received setting information (step S124). Then, the suction device 100 transmits a setting completion notification to the terminal device 200 (step S126). Note that the processing relating to steps S122 to S126 is omitted if no user input to change the settings of the suction device 100 is performed on the terminal device 200.

Next, the terminal device 200 sends a log request to the suction device 100 requesting that log information be sent (step S128).

Next, when the suction device 100 receives the log request, it transmits the requested log information to the terminal device 200 (step S130). For example, the suction device 100 transmits the information acquired during the heating sessions in steps S112 to S116 as log information.

After that, the suction device 100 and the terminal device 200 disconnect (step S132). For example, the suction device 100 disconnects from the terminal device 200 if no user operation is detected for a predetermined period of time or more and a log request is not received.

6 is a sequence diagram showing an example of the flow of the overall process related to charging executed in the system 1 according to this embodiment. The suction device 100 and the terminal device 200 are involved in this sequence.

As shown in Figure 6, first, the suction device 100 starts charging (step S202). The suction device 100 starts charging when it is connected to an external power source.

Next, the suction device 100 and the terminal device 200 establish a connection (step S204). For example, the suction device 100 transmits an advertisement, and the suction device 100 and the terminal device 200 that receives the advertisement perform a procedure to establish a connection.

Next, the suction device 100 transmits the battery information to the terminal device 200 (step S206).

Next, the suction device 100 transmits status information including information indicating the charging status of the power supply unit 111 to the terminal device 200 (step S208).

Next, the suction device 100 determines whether charging has been completed (step S210). The suction device 100 ends charging when the connection to the external power source is released. If it is determined that charging has not been completed (step S210: NO), the process returns to step S208.

If it is determined that charging has been completed (step S210: YES), the suction device 100 transmits status information including information indicating the charging status of the power supply unit 111 and battery information to the terminal device 200 (step S212).

Next, the terminal device 200 transmits the setting information to the suction device 100 (step S214). Next, when the suction device 100 receives the setting information, it performs setting based on the received setting information (step S216). Then, the suction device 100 transmits a setting completion notification to the terminal device 200 (step S218). Note that the processing relating to steps S214 to S218 is omitted if no user input to change the setting of the suction device 100 is performed on the terminal device 200.

Next, the terminal device 200 sends a log request to the suction device 100 requesting that log information be sent (step S220).

Next, when the suction device 100 receives the log request, it transmits the requested log information to the terminal device 200 (step S222). For example, the suction device 100 transmits information acquired during charging performed in steps S202 to S210 as log information.

After that, the suction device 100 and the terminal device 200 disconnect (step S224). For example, the suction device 100 disconnects from the terminal device 200 if no user operation is detected for a predetermined period of time or more and no log request is received.

- Connection Control Processing According to Remaining Power Amount FIG. 7 is a flowchart showing an example of the flow of connection control processing according to remaining power amount executed in the suction device 100 according to this embodiment.

7, first, the control unit 116 determines whether an operation to change the state of the lid unit 14 to the open state has been performed (step S302). For example, when the state of the lid unit 14 changes from a closed state to an open state, the control unit 116 determines that an operation to change the state of the lid unit 14 to the open state has been performed. When it is determined that an operation to change the state of the lid unit 14 to the open state has not been performed (step S302: NO), the control unit 116 waits until an operation to change the state of the lid unit 14 to the open state is performed.

If it is determined that an operation has been performed to open the lid portion 14 (step S302: YES), the control unit 116 determines whether the remaining power of the power supply unit 111 is less than the connection threshold (step S304).

If it is determined that the remaining power of the power supply unit 111 is less than the connection threshold (step S304: YES), the control unit 116 does not execute the connection procedure (step S306). Then, the process ends.

If it is determined that the remaining power of the power supply unit 111 is equal to or greater than the connection threshold (step S304: NO), the control unit 116 executes the connection procedure (step S308). Then, the process ends.

<<3. Supplementary Information>>
Although the preferred embodiment of the present invention has been described in detail above with reference to the accompanying drawings, the present invention is not limited to such an example. It is clear that a person having ordinary knowledge in the technical field to which the present invention pertains can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

In the above embodiment, the transmission of advertisements and pairing are given as examples of the connection procedure controlled based on whether the remaining power of the power supply unit 111 is less than the connection threshold, but the present invention is not limited to such examples. The connection procedure controlled based on whether the remaining power of the power supply unit 111 is less than the connection threshold may include power supply from the power supply unit 111 to the communication unit 115. That is, the control unit 116 may execute power supply to the communication unit 115 when the remaining power of the power supply unit 111 is equal to or greater than the connection threshold, and may not execute power supply to the communication unit 115 when the remaining power of the power supply unit 111 is less than the connection threshold. For example, the control unit 116 stops power supply to the communication unit 115 when the remaining power of the power supply unit 111 becomes less than the connection threshold while power is being supplied to the communication unit 115 (e.g., a Bluetooth communication module). According to this configuration, when the remaining power of the power supply unit 111 is less than the connection threshold, the communication function of the suction device 100 itself is stopped. This reduces the power consumption related to communication itself, making it possible to more reliably avoid situations in which the remaining power is insufficient.

In the above embodiment, an example has been described in which the inhalation device 100 generates an aerosol by heating the stick-shaped substrate 150 as a substrate containing an aerosol source, but the shape of the substrate is not limited to a stick shape. Another example of the substrate shape is a card shape. Another example of the substrate shape is a cube shape. The inhalation device 100 may also generate an aerosol to be inhaled by a user using a capsule-shaped substrate that does not contain an aerosol source and contains, for example, only a flavor source. As an example, a capsule-shaped second substrate containing a flavor source is disposed downstream of a first substrate containing an aerosol source. Then, when the aerosol generated by heating the first substrate passes through the second substrate, the aerosol is flavored from the flavor source contained in the second substrate and delivered to the user.

The series of processes performed by each device described in this specification may be realized using software, hardware, or a combination of software and hardware. The programs constituting the software are stored in advance, for example, in a recording medium (non-transitory media) provided inside or outside each device. Each program is then loaded into RAM when executed, for example, by a computer that controls each device described in this specification, and executed by a processor such as a CPU. The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, etc. The computer program may also be distributed, for example, via a network, without using a recording medium.

In addition, the processes described in this specification using flowcharts and sequence diagrams do not necessarily have to be performed in the order shown. Some processing steps may be performed in parallel. Furthermore, additional processing steps may be employed, and some processing steps may be omitted.
