Description

Aerosol generating device {AEROSOL GENERATING DEVICE}

The present disclosure relates to an aerosol generating device.

An aerosol generator is designed to extract a specific component from a medium or substance through an aerosol. The medium may contain various components. The components contained in the medium may include various flavoring substances. For example, the components contained in the medium may include nicotine, herbal ingredients, and/or coffee ingredients. Recently, extensive research has been conducted on such aerosol generators.

In a conventional aerosol generating device, an object such as a stick may be inserted into the device without a cartridge installed. In this case, the aerosol generating device cannot normally generate aerosol. However, a conventional aerosol generating device has a problem in that it cannot determine whether a cartridge is installed when an object such as a stick is inserted into the device, and it cannot provide an alarm to the user regarding a cartridge not being installed. In addition, when a cartridge is not installed, power is supplied to a terminal for supplying power to the cartridge or to a heater for heating the stick, which may cause the device to operate unstable and malfunction.

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

Another object may be to provide an aerosol generating device that determines whether a cartridge is engaged with a body based on the body receiving or approaching an object.

Another object may be to provide an aerosol generating device that outputs a relevant alarm based on whether a cartridge is engaged with a body, while the body is receiving or in proximity to an object.

Another object may be to provide an aerosol generating device that controls whether power is supplied to the heater based on whether a cartridge is coupled to the body, while the body is receiving or in proximity to an object.

Another object may be to provide an aerosol generating device that determines whether a cartridge is engaged via a cartridge power supply terminal based on an object being received or brought into proximity to the body.

According to one aspect of the present disclosure for achieving the above-described object, there is provided an aerosol generating device comprising: a body; a cartridge coupled to the body and including a heater for heating an aerosol generating substance; a sensor disposed on the body; and a control unit, wherein the control unit determines whether an object is received or approached by the body based on a signal output from the sensor, and determines whether the cartridge is coupled to the body based on the object being received or approached.

According to at least one embodiment of the present disclosure, user convenience can be improved by determining whether a cartridge is engaged with a body based on an object being received or brought into proximity to the body, and outputting a related alarm.

According to at least one embodiment of the present disclosure, by determining whether a cartridge is engaged with a body based on whether an object is received or brought into proximity to the body and controlling whether power is supplied to the heater, unnecessary power supply to the cartridge or to the heater can be prevented, and operation of the device can be prevented from becoming unstable or malfunctioning.

According to at least one embodiment of the present disclosure, when an object is received or approached by the body, it is possible to prevent unnecessary power waste for checking whether the cartridge is coupled by determining whether the cartridge is coupled through the cartridge power supply terminal.

Further scope of the applicability of the present disclosure will become apparent from the detailed description below. However, since various modifications and variations within the spirit and scope of the present disclosure will be apparent to those skilled in the art, it should be understood that the detailed description and specific examples, such as preferred embodiments of the present disclosure, are given by way of example only.

The heater (18) may be electrically connected to a power source (11). The heater (18) may be directly heated by receiving current from the power source (11).

For example, the aerosol generator (1) 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 penetrate the heater (18) and generate an eddy current 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 cartridge (19) may be formed integrally with the body (10) or may be detachably coupled to the body (10).

For example, referring to FIG. 2, the cartridge (19) is formed integrally with the body (10) and can communicate with the insertion space through an airflow channel (CN).

For example, referring to FIG. 3, a space is formed on one side of the body (10), and at least a portion of the cartridge (19) is inserted into the space formed on one side of the body (10) so that the cartridge (19) can be mounted on the body (10). The airflow channel (CN) can be defined by a portion of the cartridge and/or a portion of the body (10), and the cartridge (19) can communicate with the insertion space through the airflow channel (CN).

The cartridge (19) can generate an aerosol. The aerosol can be generated as the liquid delivery means is heated by the cartridge heater (24). The aerosol can be generated by heating the stick (S) by the heater (18). Tobacco material can be added to the aerosol while the aerosol generated by the cartridge heater (24) and the heater (18) passes through the stick (S), and the aerosol added with the tobacco material can be inhaled into the user's mouth through one end of the stick (S).

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 cartridge heater (18, 24) so that the operation of the heater (18, 24) 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 (18, 24) and the time for which the power is supplied so that the heater (18, 24) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor (13).

The sensor (138) may be a proximity sensor. The sensor (138) may be an optical proximity sensor. For example, the sensor (138) may be an infrared sensor. The infrared sensor may include a sensing light-emitting unit that emits infrared light toward the outside. The infrared sensor may include a sensing light-receiving unit that receives infrared light. Infrared light emitted from the sensing light-emitting unit may be reflected from an object and enter the sensing light-receiving unit. The sensing light-receiving unit may obtain information about the entered infrared light.

Meanwhile, the sensor (138) may include at least one of a magnetic proximity sensor, an ultrasonic proximity sensor, and an inductive proximity sensor.

The control unit (12) can receive a signal output by the sensor (138). Based on the signal output by the sensor (138), the control unit (12) can determine whether an object is received or approached the body (A10). According to the present embodiment, the control unit (12) can determine whether a stick (S) is received or inserted through the sensor (138). However, depending on the range of the signal output by the sensor (138), the control unit (12) can also determine that a cartridge (A19) is received or mounted in addition to the stick (S).

For example, the control unit (12) may determine that the first object is received or is in proximity to the body (A10) when the signal output from the sensor (138) has a value within the first range. The control unit (12) may determine that the first object is not received or is not in proximity to the body (A10) when the signal output from the sensor (138) has a value outside the first range. Here, the first object may be a stick (S).

For example, the control unit (12) may determine that a second object is accommodated in or near the body (A10) when the signal output from the sensor (138) has a value within the second range. The control unit (12) may determine that a second object is not accommodated in or near the body (A10) when the signal output from the sensor (138) has a value outside the second range. Here, the second object may be a cartridge (A19).

If it is determined that an object is accommodated or is close to the body (A10) ('Yes' in S620), the control unit (12) can determine whether to couple the cartridge (A19) to the body (A10) (S630).

The cap (A30) can be coupled to the body (A10). The cap (A30) can cover or surround the upper body (A420). When the cartridge (A19) is mounted on the body (A10), the cap (A30) can cover or surround the upper body (A420) and the cartridge (A19).

The cap (A30) may include a cover (A310). The cover (310) may open and close the insertion port (A304). When the cap (A30) is coupled to the body (A10), the insertion port (A304) is aligned with the opening of the insertion space (A214).

The stick (S) can be accommodated or inserted into the body (A10). When the stick (S) pushes the cover (310), the cover (310) can pivot toward the inside of the cap (A30) to open the insertion port (A304). When the cartridge (A19) is not coupled to the body (A10) (see FIG. 7), the stick (S) can be accommodated or inserted into the body (A10) by pushing the cover (310) of the cap (A30) and penetrating the insertion port (A304). The inserted stick (S) can be supported by the cover (310) and the upper body (A440). In a state where the cartridge (A19) is coupled to the body (A10) (see FIG. 8), the stick (S) can be inserted into the insertion space (A214) of the cartridge (A19) by pushing out the cover (310) of the cap (A30) and penetrating the insertion port (A304). The inserted stick (S) can be supported by the cover (310) and the inner wall (A212) of the first container (A210).

The control unit (12) can determine whether the stick (S) is received in the insertion port (A304) and/or the body (A10) based on the signal output from the sensor (138). The control unit (12) can determine whether the cartridge (19) is engaged based on the stick (S) being received in the insertion port (A304) and/or the body (A10).

The control unit (12) can determine whether the cartridge (A19) is connected to the body (A10) via the power supply terminal (A428).

The power supply terminal (A428) may be disposed on the body (A10). The power supply terminal (A428) may be disposed on the bottom surface of the mount (A430). The power supply terminal (A428) may be electrically connected to the power source (11). When the cartridge (A19) is coupled to the body (A10), the power supply terminal (A428) may be in contact with the connection terminal (A231) provided on the cartridge (A19). The power supply terminal (A428) may be electrically connected to a heater (A242) (e.g., heater (24)) through the connection terminal (A231). The heater (A242) may wind a wick (A241) (e.g., liquid delivery means) or may be in contact with one side of the wick (A241). The wick (A241) can be impregnated with an aerosol production material from the storage unit (C0). The heater (A242) heats the wick (A241) so that an aerosol can be generated. The power supply terminal (A428) can be referred to as a cartridge terminal.

The control unit (12) can control the power supply (11) so that a predetermined current is applied through the power supply terminal (A428) based on whether the stick (S) is received or is in proximity. The control unit (12) can determine whether the cartridge (A19) is engaged based on whether a current corresponding to the predetermined current is received through the power supply terminal (A428). For example, the control unit (12) can control the power supply (11) to transmit a pulse current through one of the power supply terminals (A428). The control unit (12) can determine whether the cartridge (A19) is engaged based on whether a pulse current is received through another of the power supply terminals (A428).

The control unit (12) can control the power supply (11) to cut off the current supply to the power supply terminal (A428) based on whether the stick (S) is not received or is not in proximity. That is, the control unit (12) determines whether the stick (S) is received or in proximity through the sensor (138), and can determine whether the cartridge (A19) is engaged through the power supply terminal (A428) only when it determines that the stick (S) is received or in proximity to the body (A10).

Accordingly, unnecessary power waste can be prevented to check whether the cartridge is combined.

Meanwhile, if it is determined that the object is not accommodated or is not close to the body (A10) ('No' in S620), the control unit (12) can repeatedly receive the signal output by the sensor (138).

If it is determined that the cartridge (A19) is not coupled to the body (A10) ('No' in S640), the control unit (12) can control the power supply (11) to cut off the power supply to the heater (A242) (S670).

Referring to Fig. 7, there may be a case where the cap (A30) is coupled to the body (A10) while the cartridge (A19) is not coupled to the body (A10). While the cartridge (A19) is not coupled to the body (A10), the stick (S) may be received or inserted into the body (A10) by the user. The stick (S) may be received or inserted into the body (A10) by pushing out the cover (310) of the cap (A30) and penetrating through the insertion port (A304).

That is, the control unit (12) can control the power supply (11) to cut off the power supply to the heater (A242) when the cartridge (A19) is not coupled to the body (A10), even if the stick (S) is accommodated in the body (A10).

Accordingly, it is possible to prevent unnecessary power supply to the cartridge (A19) or the heater (A242), and to prevent the operation of the aerosol generator (1) from becoming unstable or malfunctioning.

If it is determined that the cartridge (A19) is not coupled to the body (A10) ('No' in S640), the control unit (12) can output a first alarm through the output unit (14) (S680). The first alarm may include information related to the non-coupling of the cartridge (A19). For example, the first alarm may include at least one of information indicating that the stick (S) is received in the body (A10) and the cartridge (A19) is not coupled, information inducing coupling of the cartridge (A19), and information indicating the heating cutoff of the heater (24).

Accordingly, user convenience can be improved.

If it is determined that the cartridge (A19) is coupled to the body (A10) ('Yes' in S640), the control unit (12) can control the power supply (11) to supply power to the heater (24) (S650).

Referring to Fig. 8, when the cartridge (A19) and the cap (A30) are combined with the body (A10), the stick (S) can be received or inserted into the body (A10) by the user. The stick (S) can be inserted into the insertion space (A214) of the cartridge (A19) by pushing out the cover (310) of the cap (A30) and penetrating the insertion port (A304).

That is, the control unit (12) can control the power source (11) to supply power to the heater (24) based on the stick (S) being accommodated in the body (A10) and the cartridge (A19) being coupled to the body (A10).

Accordingly, in a state where the stick (S) is accommodated in the body (A10) and the cartridge (A19) is determined to be coupled to the body (A10), power can be supplied to the heater (A242) to normally generate an aerosol.

Meanwhile, the body (A10) may further be equipped with a cap detection sensor (136, see FIG. 12). The cap detection sensor (136) can detect the attachment and/or removal of the cap (A30). The cap detection sensor (136) may be implemented by a contact sensor, a Hall sensor (hall IC), an optical sensor, or the like.

The control unit (12) can determine whether the cap (A30) is coupled to the body (A10) based on a signal output from the cap detection sensor (136). The control unit (12) can determine whether the cap (A30) is coupled based on the stick (S) being accommodated in the body (A10) and the cartridge (A19) being coupled to the body (A10).

The control unit (12) can control the power supply (11) to supply power to the heater (24) based on the stick (S) being accommodated in the body (A10) and the cartridge (A19) and the cap (A30) being coupled to the body (A10). If the control unit (12) determines that the cap (A30) is not coupled to the body (A10) even though the stick (S) is accommodated in the body (A10) and the cartridge (A19) is coupled to the body (A10), the control unit (12) can control the power supply (11) to cut off the power supply to the heater (A242).

If it is determined that the cartridge (A19) is coupled to the body (A10) ('Yes' in S640), the control unit (12) may output a second alarm (S660) via the output unit (14, see FIG. 12). The second alarm may include information related to the insertion of the stick. For example, the second alarm may include at least one of information indicating that the stick (S) has been received in the body (A10) and information indicating the start of heating of the heater (24).

Accordingly, user convenience can be improved.

Figures 9 and 10 are cross-sectional views illustrating a stick accommodated in an aerosol generating device according to another embodiment of the present disclosure, with the cartridge either engaged or disengaged. Any features that overlap with the descriptions provided with reference to Figures 6 to 8 will be omitted for brevity.

Referring to FIGS. 9 and 10 together with FIG. 6, an insertion space (B134) may be provided in the body (B10). The insertion space (B134) may be located inside the upper body (B120). The cartridge coupling space (B124a) may be formed on one side of the upper body (B120). The cartridge coupling space (B124a) may be defined by the mounting portion (B122), the partition wall (B125), and the extension portion (B140) of the upper body (B120).

The sensor (138) may be arranged on one side of the body (B10). The sensor (138) may be arranged on the upper part of the upper body (B120). The sensor (138) may face the cartridge coupling space (B124a). When the cartridge (B19) is coupled to the body (B10), the sensor (138) may face the cartridge (B19). The sensor (138) may be arranged adjacent to the insertion space (B134). The sensor (138) may be arranged adjacent to the insertion opening (B214) of the cap (B200, see FIG. 5). When the cap (B200) is coupled to the body (B10), the sensor (138) may be positioned adjacent to the insertion opening (B214) of the cap (B200).

The sensor (138) may be disposed spaced apart from the second heater (B18) (e.g., heater (18)). The heater (B18) may be disposed around the insertion space (B134). The second heater (B18) may be disposed to surround at least a portion of the insertion space (B134). The second heater (B18) may heat the insertion space (B134) or the stick (S) inserted into the insertion space (B134). In the longitudinal direction of the insertion space (B134), the sensor (138) may be disposed above the second heater (B18). The second heater may be referred to as a stick heater or a cigarette heater.

The control unit (12) can receive a signal output by the sensor (138). Based on the signal output by the sensor (138), the control unit (12) can determine whether an object is received or approached by the body (B10). Based on the signal output by the sensor (138), the control unit (12) can determine whether a stick (S) is received or inserted into the insertion space (B134).

The control unit (12) can determine whether to couple the cartridge (B19) to the body (B10) based on whether an object is received or inserted into the insertion space (B134).

The control unit (12) can determine whether the cartridge (B19) is coupled to the body (B10) via the power supply terminal (B128). The power supply terminal (B128) can be arranged on the upper surface of the lower body (B110). The power supply terminal (B128) can be electrically connected to the power source (11). When the cartridge (B19) is coupled to the body (B10), the power supply terminal (B128) can come into contact with the connection terminal (B331) provided in the cartridge (B19). The power supply terminal (B128) can be electrically connected to a heater (B342) (e.g., heater (24)) via the connection terminal (B331). The heater (B342) can wind a wick (B341) (e.g., liquid delivery means) or can be in contact with one side of the wick (B341). The wick (B341) can be impregnated with an aerosol production material of the storage unit (C0). The heater (B342) heats the wick (B341) so that an aerosol can be generated.

The control unit (12) can control the power supply (11) so that a predetermined current is applied through the power supply terminal (B128) based on whether the stick (S) is received or is in proximity. The control unit (12) can determine whether the cartridge (B19) is engaged based on whether a current corresponding to the predetermined current is received through the power supply terminal (B128). For example, the control unit (12) can control the power supply (11) to transmit a pulse current through one of the power supply terminals (B128). The control unit (12) can determine whether the cartridge (B19) is engaged based on whether a pulse current is received through another of the power supply terminals (B128).

If it is determined that the cartridge (B19) is not coupled to the body (B10), the control unit (12) can control the power supply (11) to cut off the power supply to the heater (B342).

Referring to Fig. 9, regardless of whether the cartridge (B19) is coupled to the body (B10), the stick (S) can be accommodated or inserted into the insertion space (B134). That is, the control unit (12) can control the power supply (11) to cut off the power supply to the heater (B342) if the cartridge (B19) is not coupled to the body (B10), even if the stick (S) is accommodated in the body (B10).

If it is determined that the cartridge (B19) is not coupled to the body (B10), the control unit (12) can control the power supply (11) to cut off the power supply to the second heater (B18). That is, even if the stick (S) is accommodated in the body (B10), the control unit (12) can control the power supply (11) to cut off the power supply to the second heater (B18) if the cartridge (B19) is not coupled to the body (B10).

When the stick (S) is heated by the second heater (B18) without the cartridge (B19) being engaged, aerosol may be generated. However, when only the stick (S) is heated without the aerosol atomized in the cartridge (B19), a user who inhales only the aerosol generated by the stick (S) may experience a foreign sensation or discomfort.

In an aerosol generating device according to one embodiment of the present disclosure, when the cartridge (B19) is not coupled to the body (B10), the power supply to the second heater (B18) is cut off, thereby preventing a foreign sensation or discomfort that may be felt by the user.

Referring to Fig. 10, when the cartridge (B19) is coupled to the body (B10), the stick (S) can be received or inserted into the body (B10) by the user. The stick (S) can be inserted into the insertion space (B134) of the body (B10).

That is, the control unit (12) can control the power source (11) to supply power to the heater (B342) based on the stick (S) being accommodated in the body (B10) and the cartridge (B19) being coupled to the body (B10).

Accordingly, in a state where the stick (S) is accommodated in the body (B10) and the cartridge (B19) is determined to be coupled to the body (B10), power can be supplied to the heater (B342) to normally generate an aerosol.

Although not shown in Fig. 10, when the cartridge (B19) and the cap (B200) are coupled to the body (B10), the stick (S) can be received or inserted into the body (B10) by the user. The stick (S) can be inserted into the insertion space (B134) of the cartridge (B19) by passing through the insertion port (B214) while the door (215) of the cap (B200) is open.

Fig. 11 is a cross-sectional view showing a state in which a cartridge is coupled in an aerosol generating device according to another embodiment of the present disclosure. Any features that overlap with the descriptions provided with reference to Figs. 6 to 10 will be omitted for brevity.

Referring to FIG. 11 together with FIG. 6, the aerosol generating device (1) may include a body (C10) and a cartridge (C19). The cartridge (C19) may be coupled to one side of the body (C10).

The sensor (138) may be placed on one side of the body (C10). The sensor (138) may be placed on the upper side of the body (C10) where the cartridge (C19) is coupled to the body (C10). When the cartridge (C19) is coupled to the body (C10), the sensor (138) may face the cartridge (C19).

The control unit (12) can receive a signal output by the sensor (138). Based on the signal output by the sensor (138), the control unit (12) can determine whether an object is received or approached by the body (C10).

The control unit (12) can determine whether to couple the cartridge (C19) to the body (C10) based on whether an object is received in or close to the body (C10).

The control unit (12) can determine whether the cartridge (C19) is coupled to the body (C10) via the power supply terminal (C428). The power supply terminal (C428) can be arranged on the upper surface of the body (C10). The power supply terminal (C428) can be electrically connected to the power source (11). When the cartridge (C19) is coupled to the body (C10), the power supply terminal (C428) can come into contact with the connection terminal (C231) provided in the cartridge (C19). The power supply terminal (C428) can be electrically connected to a heater (C242) (e.g., heater (24)) via the connection terminal (C231). The heater (C242) can wind a wick (C241) (e.g., liquid delivery means) or can be in contact with one side of the wick (C241). The wick (C241) can be impregnated with an aerosol production material of the storage unit (C0). The heater (C242) heats the wick (C241) so that an aerosol can be generated.

The control unit (12) can control the power supply (11) so that a predetermined current is applied through the power supply terminal (C428) based on whether an object is received or is in proximity to the body (C10). The control unit (12) can determine whether or not to engage the cartridge (C19) based on whether or not a current corresponding to the predetermined current is received through the power supply terminal (C428).

Referring to Fig. 11, an object accommodated in or approaching a body (C10) may be a cartridge (C19). That is, when the acceptance or approach of an object to the body (C10) is detected by the sensor (138), the control unit (12) can determine, via the power supply terminal (C428), whether the object is a cartridge (C19).

The control unit (12) can control the power supply (11) to cut off the current supply to the power supply terminal (C428) based on whether the object is not received or is not in proximity. That is, the control unit (12) determines whether the object is received or in proximity through the sensor (138), and can determine whether the cartridge (C19) is engaged through the power supply terminal (C428) only when it determines that the object is received or in proximity to the body (C10).

Accordingly, unnecessary power waste can be prevented to check whether the cartridge is combined.

Fig. 12 is a block diagram of an aerosol generating device (1) according to one embodiment of the present disclosure.

The aerosol generator (1) 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 (1) is not limited to that illustrated in Fig. 12. That is, a person having ordinary skill in the art related to the present embodiment will understand that, depending on the design of the aerosol generator (1), some of the components illustrated in Fig. 12 may be omitted or new components may be added.

The sensor (13) can detect the status of the aerosol generator (1) or the status around the aerosol generator (1) and transmit the detected information to the control unit (12). Based on the detected information, the control unit (12) can control the aerosol generator (1) so that various functions such as controlling the operation of the cartridge heater (24) and/or 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), a cap 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 (1) 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 a 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).

A 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 (1) can correspond to the pressure of the airflow path through which the gas flows. The puff sensor (132) can be arranged in correspondence to the airflow path through which the gas flows in the aerosol generating device (1).

The insertion detection sensor (133) can detect insertion and/or removal of the stick (S). 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) can 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 the permittivity inside the insertion space. For example, the insertion detection sensor (133) can be an inductive sensor and/or a capacitance sensor.

An inductive sensor may include at least one coil. The coil of the inductive sensor may be positioned adjacent to an insertion space. For example, when a magnetic field changes around a current-flowing coil, 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 through the coil. For example, an inductive sensor can output a signal corresponding to the inductance value of the coil.

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

A reuse detection sensor (134) can detect whether the stick (S) has been reused. The reuse detection sensor (134) may be a color sensor. The color sensor can detect the color of the stick (S). The color sensor can detect the color of a portion 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 may be a wavelength of light. The color sensor may be implemented as a single component with the proximity sensor, or may be implemented as a separate component 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 positioned corresponding to a position where at least some of the wrappers whose color changes due to the aerosol are disposed 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 at least some of the wrappers are wetted by the aerosol generated by the aerosol generating device (1) while passing through the stick (S), 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 at 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 cap detection sensor (136) can detect the attachment and/or removal of the cap. When the cap is separated from the body (10), the cartridge (19) and a portion of the body (10) covered by the cap may be exposed to the outside.

For example, the power conversion circuit can be implemented using 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 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 the target of control based on a temperature profile. The control unit (12) can control the power supplied to the heater (18) by using the 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.

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).

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.

The control unit (12) can determine whether the cartridge (19) is usable. For example, the control unit (12) can determine that the cartridge (19) is unusable 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) is unusable 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.
