Description

Aerosol generation system {AEROSOL GENERATING SYSTEM}

The present disclosure relates to an aerosol generating system.

An aerosol generating device is intended to extract a certain component from a medium or substance through an aerosol. The medium may contain substances of various components. The substances contained in the medium may be flavoring substances of various components. For example, the substances contained in the medium may contain nicotine components, herbal components, and/or coffee components. Recently, much research has been conducted on such aerosol generating devices.

In an aerosol generator, the larger the battery capacity, the greater the number of usable puffs, which improves user convenience, but there is a problem in that the device becomes larger and heavier. Therefore, in the case of a conventional aerosol generator equipped with an integrated battery, there is a limit to increasing the battery capacity due to the size and weight, and thus the amount of use is limited.

In addition, since conventional aerosol generators use a single cartridge, there are limitations in the types of flavors and amount of vapor that users can experience.

The present disclosure aims to solve the above-mentioned and other problems.

Another object may be to provide an aerosol generating system having a battery inside the device while having a structure in which the battery module is removable from the device.

Another object may be to provide an aerosol generating system in which a plurality of cartridges are detachably coupled.

Another object may be to provide an aerosol generating system in which the insertion space, the airflow path, and the battery are arranged in a row, and the airflow path extending from the cartridge to the insertion space has a straight structure.

Another object may be to provide an aerosol generating system that heats a selected cartridge from among the combined cartridges.

Another object may be to provide an aerosol generating system that controls the power supplied to the cartridge depending on whether the battery modules are engaged.

According to one aspect of the present disclosure for achieving the above-described object, there is provided an aerosol generating system including: an aerosol generating device accommodating at least one cartridge; and a battery module comprising a second battery supplying power to the aerosol generating device, the battery module being detachably coupled to the aerosol generating device; wherein the aerosol generating device comprises: a body; a first cartridge detachably coupled to the body, the first cartridge having a first chamber storing a first aerosol product and a first heater heating the first aerosol product; a second cartridge detachably coupled to the body, the second cartridge having a second chamber storing a second aerosol product and a second heater heating the second aerosol product; and a first battery supplying power to at least one of the first heater and the second heater.

According to at least one embodiment of the present disclosure, the additional battery module has a detachable structure to the device, thereby enabling smooth supply of power to the device and reducing the size and weight of the device.

According to at least one embodiment of the present disclosure, a plurality of cartridges or a large-capacity single cartridge has a structure in which it is detachably coupled to the device, thereby providing a variety of flavors to the user and increasing the usage time of the cartridge.

According to at least one embodiment of the present disclosure, the device has a structure in which the insertion space, the airflow path, and the battery are arranged in a row, thereby reducing the size of the device and reducing the amount of droplets accumulating within the device.

According to at least one embodiment of the present disclosure, user convenience can be improved by heating a selected cartridge among cartridges coupled to the device.

According to at least one embodiment of the present disclosure, by controlling power supplied to the cartridge depending on whether a battery module is coupled, the cartridge can be heated even if the remaining battery power in the device is low.

Further scope of the applicability of the present disclosure will become apparent from the detailed description below.

Throughout this specification, the direction of the aerosol generator and the cartridge can be defined based on the orthogonal coordinate system. In the orthogonal coordinate system, the x-axis direction can be defined as the left-right direction of the aerosol generator and the cartridge. At this time, with respect to the origin, the direction toward +x can mean the right direction, and the direction toward -x can mean the left direction. The y-axis direction can be defined as the front-back direction of the aerosol generator and the cartridge. At this time, with respect to the origin, the direction toward +y can mean the rear direction, and the direction toward -y can mean the front direction. The z-axis direction can be defined as the up-down direction of the aerosol generator and the cartridge. With respect to the origin, the direction toward +z can mean the upward direction, and the direction toward -z can mean the downward direction.

Throughout this specification, “upstream” and “downstream” may be determined based on the direction of airflow in which the generated aerosol flows so that it is inhaled into the user’s mouth or lungs when the user inhales. For example, in FIGS. 1 to 6, since the generated aerosol flows from the connecting passage (431) to the insertion space (43), the connecting passage (431) is located upstream of the insertion space (43). “Upstream” and “downstream” may be determined relatively between components.

FIG. 1 is an exploded cross-sectional view of an aerosol generating system according to one embodiment of the present disclosure, and FIG. 2 is an assembled cross-sectional view of the aerosol generating system of FIG. 1.

Referring to FIG. 1, the aerosol generating system (1) may include an aerosol generating device (100) and a battery module (200).

The aerosol generating device (100) may include at least one of a power source (11), a control unit (12), a sensor (13), a heater (18), and a cartridge (19).

The heater (18) can include an electrical resistance heater and/or an induction heating heater.

For example, the heater (18) may be a resistive heater. For example, the heater (18) may include an electrically conductive track, and the heater (18) may be heated as current flows through the electrically conductive track. The heater (18) may be electrically connected to a power source (11). The heater (18) may be directly heated by receiving power from the power source (11).

For example, the aerosol generator (100) may include an induction coil surrounding a heater (18). The induction coil may heat the heater (18). The heater (18) may be a susceptor, and the heater (18) may be heated by a magnetic field generated by an AC current flowing through the induction coil. The magnetic field may pass through the heater (18) and generate eddy currents within the heater (18). The current may generate heat in the heater (18).

Meanwhile, a susceptor may be included inside the stick (S), and the susceptor inside the stick (S) may be heated by a magnetic field generated by an AC current flowing through the induction coil.

The first wick (25_A) may be connected to the first chamber (C1_A) and may receive liquid from the first chamber (C1_A). The first wick (25_A) may be fixed within the third chamber (C2_A). The first wick (25_A) may include a wick such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, etc. The first heater (24_A) may wind the first wick (25_A). The first heater may be referred to as a cartridge heater. The electrically conductive track of the first heater (24_A) may be formed as a coil-shaped structure that winds the first wick (25_A) or a structure that contacts one side of the first wick (25_A). The first heater (24_A) can be heated to heat the first wick (25_A). The end of the first heater (24_A) can extend to the bottom of the third chamber (C2_A) and be electrically connected to an electrode placed on one side of the first cartridge (19_A).

The first cartridge (19_A) may include a first cartridge discharge port (304_A). The first cartridge discharge port (304_A) may be formed on one side of the first cartridge (19_A). The first cartridge discharge port (304_A) may be in communication with the interior of the third chamber (C2_A).

When the first heater (24_A) is heated to heat the first wick (25_A), an aerosol may be formed from the first wick (25_A) within the third chamber (C2_A). Air passing through the first cartridge (19_A) may be discharged from the third chamber (C2_A) along with the aerosol through the first cartridge discharge port (304_A).

The second cartridge (19_B) may include a second chamber (C1_B) and a fourth chamber (C2_B). The fourth chamber (C2_B) may be provided with a second wick (25_B) and a second heater (24_B).

For example, the second mounting portion (433) may be arranged on the other side of the connecting passage (431) in a direction intersecting the longitudinal direction of the connecting passage (431) or the longitudinal direction of the upper body (10A). The first mounting portion (432) and the second mounting portion (433) may each be formed by the upper body (10A) being sunken to one side. In the longitudinal direction of the connecting passage (431) or in the direction intersecting the longitudinal direction of the upper body (10A), at least a portion of the connecting passage (431) can be arranged between the first mounting portion (432) and the second mounting portion (433).

Referring to FIG. 2 together with FIG. 1, the first cartridge (19_A) and the second cartridge (19_B) may be accommodated or mounted in either the first mounting portion (432) or the second mounting portion (433). In a state where the first cartridge (19_A) and the second cartridge (19_B) are accommodated or mounted in the first mounting portion (432) and the second mounting portion (433), the first cartridge (19_A) and the second cartridge (19_B) may face each other with the connecting passage (431) therebetween.

The connecting channel (431) may be connected to the insertion space (43) at one end in the longitudinal direction.

The first mounting portion (432) and the second mounting portion (433) may be provided with at least one electrode that contacts the electrode of the first cartridge (19_A) and/or the electrode of the second cartridge (19_B). The electrodes provided in the first mounting portion (432) and the second mounting portion (433) may be electrically connected to the first battery (11). Meanwhile, at least one electrode that contacts the electrode of the first cartridge (19_A) and/or the electrode of the second cartridge (19_B) may be provided on one side of the lower body (10B).

The first battery (11) may be provided in the lower body (10B). The upper body (10A) and the lower body (10B) may be detachably coupled to each other or may be formed integrally. The lower body (10B) may be arranged on the lower side of the upper body (10A). In the longitudinal direction of the connecting passage (431), an insertion space (43) may be arranged on the upper side of the connecting passage (431), and the first battery (11) may be arranged on the lower side of the connecting passage (431). That is, in the aerosol generating device (100), the insertion space (43), the connecting passage (431), and the first battery (11) may be arranged in the longitudinal direction of the body (10).

Accordingly, the size of the aerosol generating device (100) can be made compact.

In addition, the aerosol generated from the cartridge (19_A, 19_B) can reduce the droplets accumulating in the device by flowing through the connecting passage (431) and the insertion space (43) which are arranged in parallel and have an elongated shape.

In addition, since the aerosol generated from the first cartridge (19_A) and the aerosol generated from the second cartridge (19_B) pass through the same airflow path and are inhaled by the user, the foreign sensation that the user may feel can be minimized.

The power source (11) can supply power to operate components of the aerosol generator. The power source can be referred to as a first battery. The first battery (11) can supply power to at least one of the control unit (12), the sensor (13), the heater (18), the first heater (24_A), and the second heater (24_B). When the aerosol generator (100) includes an induction coil, the first battery (11) can supply power to the induction coil.

The battery module (200) can be detachably coupled to the aerosol generator (100). The battery module (200) can be equipped with a second battery (210). The second battery (210) can supply power to the aerosol generator (100). In a state where the battery module (200) is coupled to the aerosol generator (100), the second battery (210) can supply power to at least one heater (18, 24_A, 24_B) of the aerosol generator (100) or supply power to the first battery (11) to charge the first battery (11).

The battery module (200) may be coupled to one side of the aerosol generator (100). The battery module (200) may be coupled to one side of the aerosol generator (100) in a direction intersecting the longitudinal direction of the connection path (431) or the longitudinal direction of the body (10). A battery module connection terminal may be provided on one side of the aerosol generator (100). When the battery module (200) is coupled to the aerosol generator (100), the connection terminal of the battery module (200) and the connection terminal of the aerosol generator (100) may be electrically connected.

The battery module (200) may be equipped with a charging unit (220). The battery module (200) may receive power from the outside through the charging unit (220) to charge the first battery (11) or the second battery (210). When the battery module (200) is coupled with the aerosol generator (100), the battery module (200) may receive power from the outside through the charging unit (220) to charge the first battery (11) and/or the second battery (210). When the battery module (200) is separated from the aerosol generator (100), the battery module (200) may receive power from the outside through the charging unit (220) to charge the second battery (210).

In this way, since the additional battery module (200) has a structure that can be detachably attached to the aerosol generator (100), power can be smoothly supplied to the aerosol generator (100) and the size and weight of the aerosol generator (100) can be reduced.

The control unit (12) can control the overall operation of the aerosol generator (100). The control unit (12) can be mounted on a printed circuit board. The control unit (12) can control the operation of at least one of the power supply (11), the sensor (13), the heater (18), and the cartridge (19_A, 19_B). The control unit (12) can control the operation of a display, a motor, etc. installed in the aerosol generator. The control unit (12) can check the status of each component of the aerosol generator to determine whether the aerosol generator is in an operable state.

The control unit (12) can analyze the results detected by the sensor (13) and control the processes to be performed thereafter. For example, the control unit (12) can control the power supplied to the heater (24_A, 24_B) and/or the heater (18) of the cartridge so that the operation of the heater (24_A, 24_B) and/or the heater (18) of the cartridge is started or ended based on the results detected by the sensor (13). For example, the control unit (12) can control the amount of power supplied to the heater (24_A, 24_B) and/or the heater (18) of the cartridge and the time for which the power is supplied so that the heater (24_A, 24_B) and/or the heater (18) of the cartridge can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor (13).

The sensor (13) may include at least one of a cartridge detection sensor (135, see FIG. 11), a temperature sensor, a puff sensor, an insertion detection sensor, a color sensor, and an upper case detection sensor. For example, the sensor (13) may sense at least one of the temperature of the heater (18), the temperature of the first battery (11), and the temperature inside and outside the body (10). For example, the sensor (13) may sense a puff of a user. For example, the sensor (13) may sense whether a stick (S) is inserted into an insertion space. For example, the sensor (13) may sense whether a cartridge is mounted. For example, the sensor (13) may sense whether an upper case is mounted.

When the third cartridge (19_C) is mounted on the first mounting portion (432) and the second mounting portion (433), the electrode connected to the third heater (24_C) may come into contact with either the electrode of the first mounting portion (432) or the electrode of the second mounting portion (433).

The third cartridge (19_C) can accommodate about twice as much aerosol product material inside as the first cartridge (19_A) or the second cartridge (19_B). Accordingly, the cartridge's usage time can be increased, thereby enhancing user convenience.

For example, the third wick (25_C) and the third heater (24_C) may be provided in multiple numbers. In this case, the electrodes electrically connected to the plurality of third heaters (24_C) may be arranged on one side and the other side of the third cartridge (19_C). When the third cartridge (19_C) is mounted on the first mounting portion (432) and the second mounting portion (433), each of the electrodes connected to the plurality of third heaters (24_C) may come into contact with the electrode of the first mounting portion (432) or the electrode of the second mounting portion (433).

When the third cartridge (19_C) is equipped with a plurality of third wicks (25_C) and a third heater (24_C), when the third cartridge (19_C) is mounted on the aerosol generator (100), the control unit (12) can output information requesting which of the plurality of heaters is heated to the user through the output unit (14, see FIG. 11). The control unit (12) can receive a user input for selecting one heater from the user through the input unit (15, see FIG. 11). The control unit (12) can heat the selected heater to generate the aerosol based on the received user input. Meanwhile, the control unit (12) can receive a user input for selecting all of the plurality of heaters from the user. The control unit (12) can heat all of the selected heaters to generate the aerosol based on the received user input.

The third cartridge (19_C) is a large-capacity cartridge, and the amount of aerosol generating material accommodated inside is relatively large. Therefore, the third cartridge (19_C) is provided with multiple wicks and multiple heaters, and by using selected wicks and heaters, the life of the cartridge can be prevented from decreasing.

Additionally, as the user selects multiple heaters, the amount of vapor generated from the cartridge can be increased, thereby increasing user satisfaction.

Referring to FIG. 6, the first cartridge (19_A) and the second cartridge (19_B) may be accommodated or mounted in either the first mounting portion (432) or the second mounting portion (433). When the first cartridge (19_A) and the second cartridge (19_B) are accommodated or mounted in the first mounting portion (432) and the second mounting portion (433), the first cartridge (19_A) and the second cartridge (19B) may be arranged parallel to the connecting passage (431). The first cartridge (19_A) and the second cartridge (19B) may face each other in the longitudinal direction of the connecting passage (431) or in the longitudinal direction of the body (10).

Among the features of the aerosol generating device (100) and the battery module (200), detailed descriptions of features that overlap with the features of the aerosol generating device (100) and the battery module (200) related to FIGS. 1 to 6 will be omitted.

Referring to FIG. 7 and FIG. 8, the first cartridge (19_A) and the second cartridge (19B) can be arranged parallel to each other in the longitudinal direction of the connecting passage (431) or the longitudinal direction of the body (10).

A path (431) extending in the longitudinal direction of the body (10) may be formed in the body (10). The first cartridge (19_A) and the second cartridge (19_B) may be arranged on one side of the path (431) in a direction intersecting the longitudinal direction of the path (431). The first cartridge (19_A) and the second cartridge (19_B) may be arranged parallel to each other in the longitudinal direction of the path (431) or the longitudinal direction of the body (10).

The euro (431) is opened to the upper side of the body (10), and a mouthpiece (500) can be coupled to the upper side of the body (10). The mouthpiece (500) can have a suction path formed from one side coupled to the body (10) to the other side that comes into contact with the user's mouth.

The control unit (12) can control to supply power to both the first cartridge (19_A) and the second cartridge (19B). Flavoring can be added to the aerosol by either the first cartridge (19_A) or the second cartridge (19B). Tobacco material can be added to the aerosol by the other of the first cartridge (19_A) and the second cartridge (19B).

FIG. 9 is a flow chart for power supply depending on whether a cartridge is mounted in an aerosol generating system according to one embodiment of the present disclosure, and FIG. 10 is a flow chart for power supply depending on whether a battery module is mounted in an aerosol generating system according to one embodiment of the present disclosure.

Referring to FIG. 9, the control unit (12) can control at least one of the first battery (11) and the second battery (210).

The control unit (12) can detect whether the cartridge is mounted (S910). The control unit (12) can detect whether the cartridge is mounted when a stick (S) is inserted into the insertion space (43) or a user input is received through the input unit (15).

For example, the control unit (12) can determine whether the first cartridge (19_A) or the second cartridge (19_B) is accommodated in the first mounting unit (432) by sensing the current value flowing from the electrode provided in the first mounting unit (432), and can determine whether the first cartridge (19_A) or the second cartridge (19_B) is accommodated in the second mounting unit (433) by sensing the current value flowing from the electrode provided in the second mounting unit (433). For example, the aerosol generator (100) is provided with a cartridge detection sensor (135, see FIG. 11), and the control unit (12) can determine whether the first cartridge (19_A) or the second cartridge (19_B) is accommodated in the first mounting unit (432) and the second mounting unit (433) based on a signal received from the cartridge detection sensor (135).

The control unit (12) can determine whether the first cartridge (19_A) is received or mounted (S920). The control unit (12) can determine whether the second cartridge (19_B) is received or mounted based on the first cartridge (19_A) being mounted (S930). The control unit (12) can output information requesting the user to select a cartridge through the output unit (14) based on the fact that both the first cartridge (19_A) and the second cartridge (19_B) are mounted (S950). The control unit (12) can receive a user input corresponding to the user selection through the input unit (15) and determine the cartridge selected by the user among the first cartridge (19_A) and the second cartridge (19_B). The control unit (12) can control to supply power to the selected cartridge based on the user selection information. The control unit (12) can control at least one of the first battery (11) and the second battery (210) to supply power to the heater of the selected cartridge among the first heater (24_A) of the first cartridge (19_A) and the second heater (24_B) of the second cartridge (19_B) (S960).

The control unit (12) can control at least one of the first battery (11) and the second battery (210) to supply power to the first cartridge (19_A) based on the fact that the first cartridge (19_A) is mounted and the second cartridge (19_B) is not mounted (S970).

The control unit (12) can determine whether the second cartridge (19_B) is received or mounted based on the fact that the first cartridge (19_A) is not mounted (S940). The control unit (12) can control at least one of the first battery (11) and the second battery (210) to supply power to the second cartridge (19_B) based on the fact that the first cartridge (19_A) is not mounted and the second cartridge (19_B) is mounted (S980).

The control unit (12) can output information to the user through the output unit (14) that the cartridge is not mounted based on the fact that neither the first cartridge (19_A) nor the second cartridge (19_B) is mounted (S990). The control unit (12) can control at least one of the first battery (11) and the second battery (210) so that the power supplied to the heater (18) is cut off.

Accordingly, the convenience of the user can be improved by detecting the cartridge coupled to the aerosol generating device and heating the detected cartridge or heating a selected cartridge among the coupled cartridges.

Additionally, by using multiple cartridges, a variety of flavors can be provided to users.

Referring to FIG. 10, the control unit (12) can control at least one of the first battery (11) and the second battery (210).

The control unit (12) can detect whether the battery module (200) is mounted or coupled (S1010). For example, the control unit (12) can determine whether the battery module (200) is mounted or coupled to the aerosol generator (100) by sensing the current value flowing from the battery module connection terminal. For example, the aerosol generator (100) is equipped with a battery module detection sensor, and the control unit (12) can determine whether the battery module (200) is mounted or coupled to the aerosol generator (100) based on a signal received from the battery module detection sensor. The battery module detection sensor can be implemented by an inductance-based sensor, a capacitance-type sensor, a resistance sensor, a Hall sensor (hall IC) using the Hall effect, a contact sensor, an optical sensor, etc.

The control unit (12) can calculate the remaining capacity of the first battery (11) (S1020). For example, the control unit (12) can calculate the remaining capacity of the first battery (11) based on the voltage and/or current sensing values of the first battery (11).

The control unit (12) can determine whether the remaining capacity of the first battery (11) is equal to or greater than a set value based on the fact that the battery module (200) is coupled to the aerosol generator (100) (Y of S1030) (S1040). The control unit (12) can control at least one of the first battery (11) and the second battery (210) to supply power to at least one cartridge mounted on the first mounting unit (432) and/or the second mounting unit (433) based on the fact that the battery module (200) is coupled to the aerosol generator (100) and the remaining capacity of the first battery (11) is equal to or greater than the set value (S1060).

Here, the set value may be a battery residual capacity value at which, when power is supplied from the first battery (11) to at least one cartridge and/or heater (18), the heater cannot be sufficiently heated to generate an aerosol, or even if an aerosol is generated, the duration thereof is insufficient. The set value may be preset by experimentation, etc.

The control unit (12) can control the second battery (210) to supply power to at least one cartridge mounted on the first mounting unit (432) and/or the second mounting unit (433) based on the battery module (200) being coupled to the aerosol generator (100) and the remaining capacity of the first battery (11) being less than a set value (S1070).

The control unit (12) can determine whether the remaining capacity of the first battery (11) is equal to or greater than a set value based on the fact that the battery module (200) is not coupled to the aerosol generator (100) (N of S1030) (S1050). The control unit (12) can control the first battery (11) to supply power to at least one cartridge mounted on the first mounting unit (432) and/or the second mounting unit (433) based on the fact that the battery module (200) is not coupled to the aerosol generator (100) and the remaining capacity of the first battery (11) is equal to or greater than the set value (S1080).

The control unit (12) can output information to the user through the output unit (14) that the battery remaining capacity is insufficient based on the fact that the battery module (200) is not coupled to the aerosol generator (100) and the remaining capacity of the first battery (11) is less than a set value (S1090). The control unit (12) can control the first battery (11) so that the power supplied to at least one mounted cartridge and/or heater (18) is cut off.

Accordingly, by controlling the power supplied to the cartridge depending on whether the battery module (200) is coupled and the remaining capacity of the first battery (11), the cartridge can be heated even if the remaining capacity of the first battery in the device is insufficient.

Fig. 11 is a block diagram of an aerosol generating device (100) according to one embodiment of the present disclosure.

The aerosol generator (100) may include a power source (11), a control unit (12), a sensor (13), an output unit (14), an input unit (15), a communication unit (16), a memory (17), and at least one heater (18, 24). However, the internal structure of the aerosol generator (100) is not limited to that illustrated in FIG. 11. That is, it will be understood by those skilled in the art related to the present embodiment that some of the components illustrated in FIG. 11 may be omitted or new components may be added depending on the design of the aerosol generator (100).

The sensor (13) can detect the status of the aerosol generator (100) or the status around the aerosol generator (100) and transmit the detected information to the control unit (12). Based on the detected information, the control unit (12) can control the aerosol generator (100) so that various functions such as controlling the operation of the cartridge heater (24) and/or the heater (18), restricting smoking, determining whether a stick (S) and/or cartridge (19) is inserted, and displaying a notification are performed.

The sensor (13) may include at least one of a temperature sensor (131), a puff sensor (132), an insertion detection sensor (133), a reuse detection sensor (134), a cartridge detection sensor (135), an upper case detection sensor (136), and a movement detection sensor (137).

The temperature sensor (131) can detect the temperature at which the cartridge heater (24) and/or the heater (18) is heated. The aerosol generator (100) may include a separate temperature sensor that detects the temperature of the cartridge heater (24) and/or the heater (18), or the cartridge heater (24) and/or the heater (18) itself may serve as the temperature sensor.

The temperature sensor (131) can output a signal corresponding to the temperature of the cartridge heater (24) and/or the heater (18). For example, the temperature sensor (131) can include a resistance element whose resistance value changes in response to a change in the temperature of the cartridge heater (24) and/or the heater (18). It can be implemented by a thermistor, which is an element that utilizes the property of changing resistance depending on temperature. At this time, the temperature sensor (131) can output a signal corresponding to the resistance value of the resistance element as a signal corresponding to the temperature of the cartridge heater (24) and/or the heater (18). For example, the temperature sensor (131) can be configured as a sensor that detects the resistance value of the cartridge heater (24) and/or the heater (18). At this time, the temperature sensor (131) can output a signal corresponding to the resistance value of the cartridge heater (24) and/or the heater (18) as a signal corresponding to the temperature of the cartridge heater (24) and/or the heater (18).

The temperature sensor (131) may be placed around the power source (11) to monitor the temperature of the power source (11). The temperature sensor (131) may be placed adjacent to the power source (11). For example, the temperature sensor (131) may be attached to one side of a battery, which is the power source (11). For example, the temperature sensor (131) may be mounted on one side of a printed circuit board.

A temperature sensor (131) is placed inside the body (10) and can detect the internal temperature of the body (10).

The puff sensor (132) can detect the user's puff based on various physical changes in the airflow path. The puff sensor (132) can output a signal corresponding to the puff. For example, the puff sensor (132) can be a pressure sensor. The puff sensor (132) can output a signal corresponding to the internal pressure of the aerosol generating device. Here, the internal pressure of the aerosol generating device (100) can correspond to the pressure of the airflow path through which the gas flows. The puff sensor (132) can be arranged corresponding to the airflow path through which the gas flows in the aerosol generating device (100).

The stick detection sensor (133) can detect insertion and/or removal of the stick (S). The stick detection sensor may be referred to as an insertion detection sensor. The insertion detection sensor (133) can detect a signal change according to the insertion and/or removal of the stick (S). The insertion detection sensor (133) may be installed around the insertion space. The insertion detection sensor (133) can detect the insertion and/or removal of the stick (S) according to a change in permittivity inside the insertion space. For example, the insertion detection sensor (133) may be an inductive sensor and/or a capacitance sensor.

The inductive sensor may include at least one coil. The coil of the inductive sensor may be arranged adjacent to the insertion space. For example, when a magnetic field changes around a coil through which current flows, the characteristics of the current flowing in the coil may change according to Faraday's law of electromagnetic induction. Here, the characteristics of the current flowing in the coil may include the frequency of the alternating current, the current value, the voltage value, the inductance value, the impedance value, etc.

An inductive sensor can output a signal corresponding to the characteristics of the current flowing in the coil. For example, an inductive sensor can output a signal corresponding to the inductance value of the coil.

The capacitance sensor may include a conductor. The conductor of the capacitance sensor may be arranged adjacent to the insertion space. The capacitance sensor may output a signal corresponding to an electromagnetic characteristic of the surroundings, for example, an electrostatic capacitance of the surroundings of the conductor. For example, when a stick (S) including a wrapper made of a metal material is inserted into the insertion space, the electromagnetic characteristic of the surroundings of the conductor may be changed by the wrapper of the stick (S).

The reuse detection sensor (134) can detect whether the stick (S) is reused. The reuse detection sensor (134) can be a color sensor. The color sensor can detect the color of the stick (S). The color sensor can detect the color of a part of a wrapper that wraps the outside of the stick (S). The color sensor can detect a value for an optical characteristic corresponding to the color of an object based on light reflected from the object. For example, the optical characteristic can be a wavelength of light. The color sensor can be implemented as a single configuration with the proximity sensor, or can be implemented as a separate configuration distinct from the proximity sensor.

At least some of the wrappers constituting the stick (S) may change color due to the aerosol. The reuse detection sensor (134) may be arranged in response to a position where at least some of the wrappers whose color changes due to the aerosol are arranged when the stick (S) is inserted into the insertion space. For example, before the stick (S) is used by a user, the color of at least some of the wrappers may be a first color. At this time, as the aerosol generated by the aerosol generating device (100) passes through the stick (S), and at least some of the wrappers are wetted by the aerosol, the color of at least some of the wrappers may change to a second color. Meanwhile, the color of at least some of the wrappers may be maintained as the second color after changing from the first color to the second color.

The cartridge detection sensor (135) can detect the mounting and/or removal of the cartridge (19). The cartridge detection sensor (135) can be implemented by an inductance-based sensor, a capacitive sensor, a resistance sensor, a Hall sensor (hall IC) using the Hall effect, etc.

The upper case detection sensor (136) can detect the mounting and/or removal of the upper case. When the upper case (200) is separated from the body (10), a portion of the cartridge (19) and the body (10) covered by the upper case (200) may be exposed to the outside. The upper case detection sensor (136) can be implemented by a contact sensor, a hall sensor (hall IC), an optical sensor, or the like.

The motion detection sensor (137) can detect the movement of the aerosol generating device. The motion detection sensor (137) can be implemented with at least one of an acceleration sensor and a gyro sensor.

In addition to the sensors (131 to 137) described above, the sensor (13) may further include at least one of a battery module detection sensor, a pressure sensor, a magnetic sensor, a position sensor (GPS), and a proximity sensor. Since the function of each sensor can be intuitively inferred by a person skilled in the art from its name, a detailed description thereof may be omitted.

The output unit (14) can output information about the status of the aerosol generator (100) and provide it to the user. The output unit (14) can include at least one of a display (141), a haptic unit (142), and an audio output unit (143), but is not limited thereto. When the display (141) and the touch pad form a layered structure to form a touch screen, the display unit (141) can be used as an input device in addition to an output device.

The display (141) can visually provide information about the aerosol generator (100) to the user. For example, the information about the aerosol generator (100) can mean various information such as the charging/discharging status of the power supply (11) of the aerosol generator (100), the preheating status of the heater (18), the insertion/removal status of the stick (S) and/or cartridge (19), the mounting/removal status of the upper case, or the status in which the use of the aerosol generator (100) is restricted (e.g., detection of an abnormal item), and the display (141) can output the information to the outside. For example, the display (141) can be in the form of an LED light-emitting element. For example, the display (141) can be a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), etc.

The haptic unit (142) can convert an electrical signal into a mechanical stimulus or an electrical stimulus to provide tactile information about the aerosol generating device (100) to the user. For example, the haptic unit (142) can generate a vibration corresponding to the completion of the initial preheating when the initial power is supplied to the cartridge heater (24) and/or the heater (18) for a set period of time. The haptic unit (142) can include a vibration motor, a piezoelectric element, or an electrical stimulation device.

The acoustic output unit (143) can provide information about the aerosol generator (100) to the user audibly. For example, the acoustic output unit (143) can convert an electric signal into an acoustic signal and output it to the outside.

The power source (11) can supply power used to operate the aerosol generator (100). The power source (11) can supply power so that the cartridge heater (24) and/or the heater (18) can be heated. In addition, the power source (11) can supply power required for the operation of other components provided in the aerosol generator (100), such as a sensor (13), an output unit (14), an input unit (15), a communication unit (16), and a memory (17).

The power protection circuit can block the power path to the power source (11) according to a predetermined condition. For example, the power protection circuit can block the power path to the power source (11) when the voltage level of the power source (11) is equal to or higher than a first voltage corresponding to overcharge. For example, the power protection circuit can block the power path to the power source (11) when the voltage level of the power source (11) is lower than a second voltage corresponding to overdischarge.

The heater (18) can receive power from the power source (11) to heat the medium or aerosol generating material within the stick (S). Although not shown in FIG. 11, the aerosol generating device (100) may further include a power conversion circuit (e.g., a DC/DC converter) that converts the power of the power source (11) and supplies it to the cartridge heater (24) and/or the heater (18). In addition, when the aerosol generating device (100) generates the aerosol by induction heating, the aerosol generating device (100) may further include a DC/AC converter that converts the direct current power of the power source (11) into alternating current power.

The control unit (12), the sensor (13), the output unit (14), the input unit (15), the communication unit (16), and the memory (17) can receive power from the power supply (11) and perform their functions. Although not shown in FIG. 11, a power conversion circuit, for example, an LDO (low dropout) circuit or a voltage regulator circuit, which converts the power of the power supply (11) and supplies it to each component, may be further included. Also, although not shown in FIG. 11, a noise filter may be provided between the power supply (11) and the heater (18). The noise filter may be a low pass filter. The low pass filter may include at least one inductor and a capacitor. The cutoff frequency of the low pass filter may correspond to the frequency of the high frequency switching current applied from the power supply (11) to the heater (18). By the low pass filter, it is possible to prevent high frequency noise components from being applied to a sensor (13), such as an insertion detection sensor (133).

In one embodiment, the cartridge heater (24) and/or the heater (18) may be formed of any suitable electrically resistive material. For example, suitable electrically resistive materials may be metals or metal alloys including, but not limited to, titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nichrome, and the like. Additionally, the heater (18) may be implemented as, but is not limited to, a metal wire, a metal plate having electrically conductive tracks arranged thereon, a ceramic heating element, and the like.

In another embodiment, the heater (18) may be an induction heating type heater. For example, the heater (18) may include a susceptor that heats the aerosol generating material by generating heat through a magnetic field applied by the coil.

The input unit (15) can receive information input from a user or output information to the user. For example, the input unit (15) can be a touch panel. The touch panel can include at least one touch sensor that detects touch. For example, the touch sensor can include, but is not limited to, a capacitive touch sensor, a resistive touch sensor, a surface acoustic wave touch sensor, an infrared touch sensor, etc.

The display (141) and the touch panel may be implemented as a single panel. For example, the touch panel may be inserted (on-cell type or in-cell type) into the display (141). For example, the touch panel may be added-on (add-on type) on the display panel (141).

Meanwhile, the input unit (15) may include, but is not limited to, buttons, key pads, dome switches, jog wheels, jog switches, etc.

The processor can be implemented as an array of a plurality of logic gates, or can be implemented as a combination of a general-purpose microprocessor and a memory storing a program that can be executed in the microprocessor. In addition, it will be understood by those skilled in the art to which the present embodiment belongs that the processor can be implemented as other types of hardware.

The control unit (12) can control the temperature of the heater (18) by controlling the supply of power from the power source (11) to the heater (18). The control unit (12) can control the temperature of the cartridge heater (24) and/or the heater (18) based on the temperature of the cartridge heater (24) and/or the heater (18) sensed by the temperature sensor (131). The control unit (12) can adjust the power supplied to the cartridge heater (24) and/or the heater (18) based on the temperature of the cartridge heater (24) and/or the heater (18). For example, the control unit (12) can determine a target temperature for the cartridge heater (24) and/or the heater (18) based on a temperature profile stored in the memory (17).

The aerosol generator (100) may include a power supply circuit (not shown) electrically connected to the power supply (11) between the power supply (11) and the cartridge heater (24) and/or the heater (18). The power supply circuit may be electrically connected to the cartridge heater (24), the heater (18), or the induction coil (181). The power supply circuit may include at least one switching element. The switching element may be implemented by a bipolar junction transistor (BJT), a field effect transistor (FET), or the like. The control unit (12) may control the power supply circuit.

The control unit (12) can control power supply by controlling the switching of the switching elements of the power supply circuit. The power supply circuit may be an inverter that converts direct current power output from the power source (11) into alternating current power. For example, the inverter may be configured as a full-bridge circuit or a half-bridge circuit including a plurality of switching elements.

The control unit (12) can turn on the switching element so that power is supplied from the power source (11) to the cartridge heater (24) and/or the heater (18). The control unit (12) can turn off the switching element so that power is cut off to the cartridge heater (24) and/or the heater (18). The control unit (12) can control the current supplied from the power source (11) by controlling the frequency and/or duty ratio of the current pulse input to the switching element.

The control unit (12) can control the voltage output from the power source (11) by controlling the switching of the switching element of the power supply circuit. The power conversion circuit can convert the voltage output from the power source (11). For example, the power conversion circuit can include a buck converter that steps down the voltage output from the power source (11). For example, the power conversion circuit can be implemented through a buck-boost converter, a zener diode, etc.

The control unit (12) can control the on/off operation of the switching element included in the power conversion circuit to adjust the level of the voltage output from the power conversion circuit. When the on state of the switching element continues, the level of the voltage output from the power conversion circuit may correspond to the level of the voltage output from the power source (11). The duty ratio for the on/off operation of the switching element may correspond to the ratio of the voltage output from the power conversion circuit to the voltage output from the power source (11). As the duty ratio for the on/off operation of the switching element decreases, the level of the voltage output from the power conversion circuit may decrease. The heater (18) can be heated based on the voltage output from the power conversion circuit.

The control unit (12) can control power to be supplied to the heater (18) by using at least one of the pulse width modulation (PWM) method and the proportional-integral-differential (PID) method.

For example, the control unit (12) can control a current pulse having a predetermined frequency and duty ratio to be supplied to the heater (18) using the PWM method. The control unit (12) can control the power supplied to the heater (18) by adjusting the frequency and duty ratio of the current pulse.

For example, the control unit (12) can determine a target temperature that is a target of control based on a temperature profile. The control unit (12) can control the power supplied to the heater (18) by using a PID method, which is a feedback control method using a difference value between the temperature of the heater (18) and the target temperature, a value obtained by integrating the difference value over time, and a value obtained by differentiating the difference value over time.

The control unit (12) can prevent the cartridge heater (24) and/or the heater (18) from overheating. For example, the control unit (12) can control the operation of the power conversion circuit to cut off the supply of power to the cartridge heater (24) and/or the heater (18) based on the temperature of the cartridge heater (24) and/or the heater (18) exceeding a preset limit temperature. For example, the control unit (12) can reduce the amount of power supplied to the cartridge heater (24) and/or the heater (18) by a predetermined ratio based on the temperature of the cartridge heater (24) and/or the heater (18) exceeding a preset limit temperature.

The control unit (12) can control the charging and discharging of the power supply (11). The control unit (12) can check the temperature of the power supply (11) based on the output signal of the temperature sensor (131).

When a power line is connected to the battery terminal of the aerosol generator (100), the control unit (12) can check whether the temperature of the power source (11) is equal to or higher than the first limit temperature, which is a criterion for blocking charging of the power source (11). When the temperature of the power source (11) is lower than the first limit temperature, the control unit (12) can control the power source (11) to be charged based on a preset charging current. When the temperature of the power source (11) is equal to or higher than the first limit temperature, the control unit (12) can block charging of the power source (11).

When the power of the aerosol generator (100) is turned on, the control unit (12) can check whether the temperature of the power source (11) is equal to or higher than the second limit temperature, which is a criterion for blocking discharge of the power source (11). If the temperature of the power source (11) is lower than the second limit temperature, the control unit (12) can control to use the power stored in the power source (11).

The control unit (12) can determine that the stick (S) is inserted based on the output signal of the insertion detection sensor (133). If it is determined that the stick (S) is inserted into the insertion space, the control unit (12) can control to supply power to the cartridge heater (24) and/or the heater (18).

The control unit (12) can determine whether the stick (S) is removed from the insertion space. For example, the control unit (12) can determine whether the stick (S) is removed from the insertion space through the insertion detection sensor (133). For example, the control unit (12) can determine that the stick (S) is removed from the insertion space when the temperature of the heater (18) is higher than a limited temperature or when the temperature change slope of the heater (18) is higher than a set slope. When it is determined that the stick (S) is removed from the insertion space, the control unit (12) can cut off the power supply to the cartridge heater (24) and/or the heater (18).

The control unit (12) can determine whether the stick (S) inserted into the insertion space is reused through the reuse detection sensor (134). For example, the control unit (12) can compare the sensing value of the signal of the reuse detection sensor with a first reference range that includes a first color, and if the sensing value is included in the first reference range, it can determine that the stick (S) has not been used. For example, the control unit (12) can compare the sensing value of the signal of the reuse detection sensor with a second reference range that includes a second color, and if the sensing value is included in the second reference range, it can determine that the stick (S) has been used. If it is determined that the stick (S) has been used, the control unit (12) can cut off the supply of power to the cartridge heater (24) and/or the heater (18).

The control unit (12) can determine whether the cartridge (19) is coupled and/or removed through the cartridge detection sensor (135).

For example, the control unit (12) can preheat the cartridge heater (24) and/or the heater (18) by applying power, and determine whether the temperature of the cartridge heater (24) exceeds a limit temperature during the preheating section. If the temperature of the cartridge heater (24) exceeds the limit temperature, the control unit (12) can determine that the aerosol generating material of the cartridge (19) is exhausted. If the control unit (12) determines that the aerosol generating material of the cartridge (19) is exhausted, the control unit (12) can cut off the supply of power to the cartridge heater (24) and/or the heater (18).

The control unit (12) can determine whether the cartridge (19) is usable. For example, the control unit (12) can determine that the cartridge (19) cannot be used if the current number of puffs is greater than or equal to the maximum number of puffs set for the cartridge (19) based on data stored in the memory (17). For example, the control unit (12) can determine that the cartridge (19) cannot be used if the total time that the heater (24) has been heated is greater than or equal to the preset maximum time or the total amount of power supplied to the heater (24) is greater than or equal to the preset maximum amount of power.

The control unit (12) can perform a judgment regarding the user's inhalation through the puff sensor (132). For example, the control unit (12) can determine whether a puff has occurred based on the sensing value of the signal of the puff sensor. For example, the control unit (12) can determine the intensity of the puff based on the sensing value of the signal of the puff sensor (132). If the number of puffs reaches a preset maximum number of puffs or if no puffs are detected for a preset time or longer, the control unit (12) can cut off the supply of power to the cartridge heater (24) and/or heater (18).

The control unit (12) can determine whether the upper case is joined and/or removed through the upper case detection sensor (136).

For example, the control unit (12) can notify the user through the output unit (14) based on the determination that the stick (S) does not exist in the insertion space. For example, the control unit (12) can notify the user through the output unit (14) based on the determination that the cartridge (19) and/or the upper case is not mounted. For example, the control unit (12) can transmit information on the temperature of the cartridge heater (24) and/or the heater (18) to the user through the output unit (14).
