Memory 140 can store programs for each signal processing and control within control unit 170, and can store data processed by control unit 170 and data to be processed.

For example, the memory 140 may store application programs designed to perform various tasks that can be processed by the control unit 170, and may selectively provide some of the stored application programs upon request from the control unit 170.

For example, the memory 140 may store the operating time of the aerosol generating device 100, the maximum number of puffs, the current number of puffs, the number of times the battery 160 has been charged, the number of times the battery 160 has been discharged, at least one temperature profile, data on the user's inhalation pattern, data on charging and discharging, etc. Here, a puff may refer to the user's inhalation, and inhalation may be a situation in which the user inhales through the mouth or nose into the user's oral cavity, nasal cavity, or lungs.

Memory 140 may include at least one of volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) and non-volatile memory (e.g., flash memory, hard disk drive (HDD), solid-state drive (SSD), etc.).

The sensor module 150 may include at least one sensor.

For example, the sensor module 150 may include a sensor that detects puffs (hereinafter referred to as a puff sensor). Here, the puff sensor may be implemented as a proximity sensor such as an IR sensor, a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, etc.

For example, the sensor module 150 may include a sensor that detects puffs (hereinafter referred to as a puff sensor). Here, the puff sensor may be embodied as a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, etc.

For example, the sensor module 150 may include a sensor (hereinafter referred to as a temperature sensor) that detects the temperature of the heater included in the aerosol generation module 130, the temperature of the aerosol-generating material, etc. Here, the heater included in the aerosol generation module 130 may also function as a temperature sensor. For example, the electrically resistive material of the heater may be a material having a temperature coefficient of resistance. The sensor module 150 may sense the temperature of the heater by measuring the resistance of the heater, which changes depending on the temperature.

For example, if a stick can be inserted into the main body of the aerosol generating device 100, the sensor module 150 may include a sensor that detects the insertion of the stick (hereinafter referred to as a stick detection sensor).

For example, if the aerosol generating device 100 includes a cartridge, the sensor module 150 may include a sensor (hereinafter referred to as a cartridge detection sensor) that detects the attachment/detachment and position of the cartridge relative to the main body.

Here, the stick detection sensor and/or cartridge detection sensor can be implemented using an inductance-based sensor, a capacitance-type sensor, a resistance sensor, a Hall sensor (hall IC) using the Hall effect, etc.

For example, the sensor module 150 may include a voltage sensor that detects the voltage applied to a component (e.g., battery 160) provided in the aerosol generating device 100 and/or a current sensor that detects the current.

The battery 160 can supply power used for the operation of the aerosol generating device 100 under the control of the control unit 170. The battery 160 can supply power to other components included in the aerosol generating device 100. For example, the battery 160 can supply power to the communication module included in the communication interface 110, the output device included in the input/output interface 120, the heater included in the aerosol generating module 130, etc.

The battery 160 may be a rechargeable battery or a disposable battery. For example, the battery 160 may be, but is not limited to, a lithium-ion battery or a lithium polymer (Li-Polymer) battery. For example, if the battery 160 is rechargeable, the charge rate (C-rate) of the battery 160 may be, but is not limited to, 10C and the discharge rate (C-rate) may be 10C to 20C. In addition, for stable use, the battery 160 may be manufactured to maintain 80% or more of its total capacity even after 2,000 charge/discharge cycles.

The aerosol generating device 100 may further include a protection circuit module (PCM), which is a circuit for protecting the battery 160. The protection circuit module (PCM) may be disposed adjacent to the upper surface of the battery 160. For example, to prevent overcharging and over-discharging of the battery 160, the protection circuit module (PCM) may cut off the electrical path to the battery 160 when a short circuit occurs in a circuit connected to the battery 160, when an overvoltage is applied to the battery 160, when an overcurrent flows through the battery 160, etc.

The aerosol generating device 100 may further include a charging terminal to which externally supplied power is input. For example, a charging terminal may be formed on one side of the body of the aerosol generating device 100, and the aerosol generating device 100 may charge the battery 160 using power supplied through the charging terminal. Here, the charging terminal may be a wired terminal for USB communication, a pogo pin, or the like.

The aerosol generating device 100 can also wirelessly receive power supplied from an external source via the communication interface 110. For example, the aerosol generating device 100 can receive power wirelessly using an antenna included in a communication module for wireless communication, and can charge the battery 160 using the wirelessly supplied power.

The control unit 170 can control the overall operation of the aerosol generating device 100. The control unit 170 is connected to each component provided in the aerosol generating device 100 and can transmit and/or receive signals between each component to control the overall operation of each component.

The control unit 170 may include at least one processor and may use the processor to control the overall operation of the aerosol generating device 100. Here, the processor may be a general processor such as a CPU (central processing unit). Of course, the processor may be a dedicated device such as an ASIC or a processor based on other hardware.

The control unit 170 can perform any one of the multiple functions of the aerosol generating device 100. For example, the control unit 170 can execute any one of the multiple functions of the aerosol generating device 100 (e.g., preheating function, heating function, charging function, cleaning function, etc.) depending on the state of each component provided in the aerosol generating device 100, user commands received via the input/output interface 120, etc.

The control unit 170 can control the operation of each component of the aerosol generating device 100 based on the data stored in the memory 140. For example, the control unit 170 can control the battery 160 to supply a predetermined amount of power to the aerosol generating module 130 for a predetermined period of time based on data about the temperature profile, the user's inhalation pattern, etc. stored in the memory 140.

The control unit 170 can determine whether a puff has occurred through the puff sensor included in the sensor module 150. For example, the control unit 170 can check temperature changes, flow rate changes, pressure changes, voltage changes, etc. within the aerosol generating device 100 based on the sensing values of the puff sensor, and can determine whether a puff has occurred based on the results of the check based on the sensing values of the puff sensor.

The control unit 170 can control the operation of each component of the aerosol generating device 100 depending on whether or not a puff is performed and/or the number of puffs. For example, the control unit 170 can control the heater temperature to be changed or maintained based on the temperature profile stored in the memory 140.

The control unit 170 may control the heater to cut off power supply under certain conditions. For example, the control unit 170 may control the heater to cut off power supply when the stick is removed and the cartridge is separated, when the number of puffs reaches a preset maximum number of puffs, when no puffs are detected for a preset time, or when the remaining charge of the battery 160 is less than a predetermined value.

The control unit 170 may calculate the remaining amount of power (hereinafter referred to as the remaining amount) stored in the battery 160. For example, the control unit 170 may calculate the remaining amount of power in the battery 160 based on the sensing values of the voltage sensor and/or current sensor included in the sensor module 150.

The control unit 170 can control the supply of power to the heater using at least one of a pulse width modulation (PWM) method and a proportional-integral-differential (PID) method.

For example, the control unit 170 can use a PWM method to control the supply of current pulses having a predetermined frequency and duty ratio to the heater. Here, the control unit 170 can control the power supplied to the heater by adjusting the frequency and duty ratio of the current pulses.

For example, the control unit 170 can determine a target temperature, which is the target for control, based on the temperature profile. Here, the control unit 170 can control the power supplied to the heater using a PID method, which is a feedback control method based on the difference between the heater temperature and the target temperature, the value obtained by integrating the difference over time, and the value obtained by differentiating the difference over time.

Meanwhile, while the PWM method and the PID method have been described as examples of control methods for supplying power to the heater, the present invention is not limited to these, and various control methods such as the Proportional-Integral (PI) method and the Proportional-Differential (PD) method can also be used.

Meanwhile, the control unit 170 can control the heater to supply power under preset conditions. For example, if a cleaning function for cleaning the heater is selected according to a command input by the user via the input/output interface 120, the control unit 170 can control the heater to supply a predetermined amount of power.

Referring to FIG. 2, the aerosol generating device 100 may include a body 10 and cartridges 20, 30. The cartridges 20, 30 may include a first container 20 and a second container 30. The cartridges 20, 30 may be coupled to the body 10.

The body 10 can house a power source 11 (e.g., battery 160 in FIG. 1) and a control unit 12 (e.g., control unit 170 in FIG. 1). The power source 11 can provide the power necessary for the configuration to operate. The power source 11 can be referred to as a battery 11. The control unit 12 can control the operation of the configuration.

The first container 20 may include a first chamber C1 therein. The first container 20 may include a wick 25. The wick 25 may be disposed in the first chamber C1. The upper end of the wick 25 may protrude from the first chamber C1 to the upper side of the first container 20.

The first container 20 may include a heater 2531. The heater 2531 may be disposed in the first chamber C1. The heater 2531 may heat the wick 25. The heater 2531 may be attached to the wick 25. The first container 20 may include a terminal 223 therein. The terminal 223 may be exposed to the underside of the first container 20. The terminal 223 may be electrically connected to the heater 2531. The first container 20 may be referred to as the lower container 20 or the heating module 20.

The first container 20 may have a first airflow inlet 241 formed by the opening of the first chamber C1. The first container 20 may have a first airflow outlet 242 formed by the opening of the first chamber C1.

The second container 30 may include a second chamber C2 therein. The second container 30 may store liquid in the second chamber C2. The second container 30 may have an airflow discharge passage 340. Both ends 341 and 342 of the airflow discharge passage 340 may be open. The airflow discharge passage 340 may be separated from the second chamber C2. The second container 30 may be referred to as an upper container 30 or a liquid storage portion 30.

The mouthpiece 35 may be attached to the upper side of the second container 30. The mouthpiece 35 may cover the top of the second container 30. The mouthpiece 35 may have a second airflow outlet 354 therein. The second airflow outlet 354 may be connected to the other end 342 of the airflow exhaust passage 340.

The first container 20 may be coupled to the body 10. The first container 20 may be inserted into the body 10. When the first container 20 is coupled to the body, the heater 2531 may be electrically connected to the power source 11 via the terminal 223. The heater 2531 may receive power from the power source 11 and generate heat. The heater 2531 may be a resistive heater.

The second container 30 can be connected to the upper side of the first container 20. Connecting the second container 30 to the first container 20 can include connecting the second container 30 directly to the first container 20, or connecting the second container 30 to the body 10 and indirectly connecting it to the first container 20.

When the second container 30 is coupled to the first container 20, the second container 30 can supply the stored liquid to the wick 25. The wick 25 can absorb the liquid supplied from the second container 30. The heater 2531 can heat the wick that has absorbed the liquid to generate an aerosol in the first chamber C1.

The body 10 may have an opening on one side to form the second airflow inlet 141. When the first container 20 is coupled to the body 10, the first airflow inlet 241 may be connected to the second airflow inlet 141. When the second container 30 is coupled to the first container 20, one end 341 of the airflow discharge passage 340 may be connected to the first airflow outlet 242. This may form a passage through which air flows. A user may inhale air by holding the mouthpiece 35 in their mouth. When the user inhales, external air may be provided to the user by sequentially passing through the second airflow inlet 141, the first airflow inlet 241, the first chamber C1, the first airflow outlet 242, the airflow discharge passage 340, and the second airflow outlet 354. The air may flow together with the aerosol generated in the first chamber C1.

The puff sensor 461 can output a signal corresponding to a puff. For example, the puff sensor 461 can output a signal corresponding to the internal pressure of the aerosol generating device 100. Here, the internal pressure of the aerosol generating device 100 can correspond to the pressure of the air flow passage through which gas flows. The puff sensor 461 can be disposed in a position corresponding to the air flow passage through which air flows in the aerosol generating device 100. For example, the puff sensor 461 can be disposed inside the body 10 adjacent to the first air flow inlet 241.

The first container 20 and the second container 30 can be replaced independently of each other. For example, the consumption cycle of the liquid stored in the second container 30 and the appropriate replacement cycle of the first container 20 may differ from each other. The user can replace only the second container 30 separately, or only the first container 20 separately. For example, the consumption cycle of the liquid stored in the second container 30 may be shorter than the appropriate replacement cycle of the first container 20, and while the second container 30 is replaced multiple times, the first container 20 can be replaced only once. This allows the first container 20 to be used for a longer period of time, reducing cartridge replacement costs.

Referring to Figures 3 to 5, the first container 20 can be detachably connected to the body 10. The first coupler 151 can detachably connect the first container 20 and the body 10 to each other. For example, the first coupler 151 can include a hook groove 225 and a hook 125 that is detachably fastened to the hook groove 225. The hook 125 can be made of a material such as rubber or silicone and can seal the space between the body and the first container 20 around the second air inlet 141. As another example, the first coupler 151 can connect the first container 20 and the body 10 using magnetic force.

The second container 30 can be detachably connected to the first container 20. The second container 30 can be attached to the upper side of the first container 20. The second container 30 can be attached to the body 10 and indirectly connected to the first container 20. The second coupler 152 can detachably connect the second container 30 and the body 10 to each other. For example, the second coupler 152 can include a hook groove 325 and a hook 135 that is detachably fastened to the hook groove 325. As another example, the second coupler 152 can connect the second container 30 and the body 10 by magnetic force.

The first container 20 can be detachably connected to the body 10. The first coupler 151 can detachably connect the first container 20 and the body 10 to each other. The second container 30 can be detachably connected to the first container 20. The second container 30 can be indirectly connected to the first container 20 by being connected to the body 10 via the second coupler 152. The second container 30 can be connected to the upper side of the first container 20.

When the second container 30 is combined with the first container 20, the second container 30 can supply liquid to the wick 25. The liquid stored in the second chamber C2 can pass through the liquid outlet 314 and be absorbed by the absorption section 316. The absorption section 316 that has absorbed the liquid can contact the second wick part 252 and transfer the liquid. The liquid absorbed in the second wick part 252 can diffuse into the first wick part 251. The heater 3531 can heat the first wick part 251 that has absorbed the liquid to generate an aerosol.

According to one embodiment, a film may be detachably attached to the absorbent portion 316. The film may be attached to the lower portion of the absorbent portion 316. The edge of the film may be attached to the lower surface of the bracket 317. The film may be made of a waterproof material. The film may prevent liquid from leaking from the absorbent portion 316. Before connecting the second container 30 to the first container 20, the user may remove the film from the absorbent portion 316.

The sealer 26 can seal the periphery of the liquid inlet 235 through which the wick 25 is exposed from the first chamber C1. When the second container 30 is attached to the top of the first container 20, the sealer 26 can seal between the first container 20 and the second container 30. The sealing walls 266 and 267 can protrude toward the second container 30. The sealing walls 266 and 267 can be tightly attached to the second container 30. The sealing walls 266 and 267 can surround the periphery of the liquid inlet 235. This can prevent liquid discharged from the second container 30 from leaking into the gap between the first container 20 and the second container 30.

The sealer 26 may include an air flow sealing portion 268. The air flow sealing portion 268 may surround the periphery of the first air flow outlet 242. The second sealing wall 267 may protrude higher than the air flow sealing portion 268. The air flow sealing portion 268 may be formed outside the sealing walls 266 and 267.

The cartridge detection sensor 471 may be installed inside the body 10. The cartridge detection sensor 471 may sense whether the second container 30 is coupled to the first container 20. The control unit 12 may control the operation of various components based on the sensing of the cartridge detection sensor 471. For example, the cartridge detection sensor 471 may be a contact sensor. The cartridge detection sensor 471 may sense whether the second container 30 is coupled to the first container 20 through physical contact. When the second container 30 is coupled to the first container 20, physical contact may occur at the cartridge detection sensor 471. The cartridge detection sensor 471 may detect the physical contact that occurs at the cartridge detection sensor 471. For example, physical contact may occur when the cartridge detection sensor 471 comes into direct contact with the second container 30. For example, physical contact may occur via an intermediary component between the cartridge detection sensor 471 and the second container 30.

The pusher 40 may be disposed between the cartridge detection sensor 471 and the second container 30. The pusher 40 may be inserted into the pusher travel path 44. The pusher 40 may include a first pusher part 41 and a second pusher part 42. The first pusher part 41 and the second pusher part 42 may be connected to each other one above the other. The pusher 40 may extend longitudinally between the cartridge detection sensor 471 and the second container 30. The pusher 40 may move between the cartridge detection sensor 471 and the second container 30. One end of the pusher 40 may be disposed adjacent to the second container 30. One end of the pusher 40 may be exposed toward the second container 30 through one end of the pusher travel path 44. The other end of the pusher 40 may be disposed adjacent to the cartridge detection sensor 471. The other end of the pusher 40 may be exposed toward the cartridge detection sensor 471 through the other end of the pusher travel path 44.

For example, the pusher 40 and the pusher movement path 44 may have a shape that extends vertically. The pusher 40 can move up and down. When the second container 30 is coupled to the top of the first container 20, the lower portion 312 of the second container 30 contacts the upper end of the pusher 40 and pushes the pusher 40 downward, so that the lower end of the pusher 40 can contact the cartridge detection sensor 471.

The cartridge detection sensor 471 can transmit a detection signal corresponding to physical contact to the control unit 12. The control unit 12 can determine whether the second container 30 is coupled to the first container 20 based on the detection signal received from the cartridge detection sensor 471.

As a result, the cartridge detection sensor 471 can detect the connection of the second container 30 to the first container 20 without the need for an additional terminal configuration for electrical connection. This simplifies the configuration of the second container 30 for sensing, reducing manufacturing costs. Furthermore, when determining whether the second container 30 is connected using a physical contact method, the impact of external noise is reduced, improving sensing accuracy.

The actuator 472 can transmit physical contact to the cartridge detection sensor 471 by being pushed by the pusher 40. The actuator 472 can be formed integrally with the cartridge detection sensor 471. The actuator 472 can protrude elongatedly from the cartridge detection sensor 471 toward the pusher 40. The actuator 472 can provide a repulsive force to the pusher 40 in a direction away from the cartridge detection sensor 471. The actuator 472 can provide a repulsive force to the pusher 40 from the other end of the pusher travel path 44 toward one end. For example, the actuator 472 can provide a repulsive force that pushes the pusher 40 upward.

When the second container 30 is coupled to the first container 20, the pusher 40 can push the actuator 472 toward the cartridge detection sensor 471. When the pusher 40 pushes the actuator 472 toward the cartridge detection sensor 471, the cartridge detection sensor 471 can detect physical contact. When the second container 30 is separated from the first container 20, the pusher 40 can move away from the cartridge detection sensor 471 due to the repulsive force of the actuator 472. Here, the pusher 40 can return to the position it was in before the second container 30 was coupled to the first container 20.

A sealing membrane 48 may be formed between the cartridge detection sensor 471 and the pusher movement path 44. The sealing membrane 48 may be formed between the actuator 472 and the pusher movement path 44. The sealing membrane 48 is made of an elastic material and is capable of deforming. For example, the sealing membrane may be made of rubber or silicone.

When the actuator 472 pushes out the sealing membrane 48, the sealing membrane 48 may have a shape that bulges toward the pusher 40. When the pusher 40 presses the cartridge detection sensor 471, the curvature of the sealing membrane 48 may decrease or the sealing membrane 48 may deform so as to bulge toward the cartridge detection sensor 471. This allows the sealing membrane 48 to prevent foreign matter such as liquid from leaking around the cartridge detection sensor 471 through the pusher movement path 44.

Although this disclosure describes the cartridge detection sensor 471 as a contact sensor, this is not limiting. According to one embodiment, the cartridge detection sensor 471 may be a non-contact sensor. For example, the cartridge detection sensor 471 may be one of a magnetic proximity sensor, an optical proximity sensor, an ultrasonic proximity sensor, an inductive proximity sensor, a capacitive proximity sensor, and an eddy current proximity sensor.

According to one embodiment, whether the first container 20 is coupled to the body 10 can be detected via a separate sensor or by the electrical connection between the second terminal 223 and the power source 11.

Referring to FIG. 6, the wick 25 can be formed of a porous rigid material that absorbs liquid. For example, the wick 25 can be formed of a porous ceramic. The wick 25 can be more rigid and heat-resistant than a cotton wick.

As a result, the core 25 undergoes little or no deformation and can be embodied in a variety of shapes. Furthermore, the durability of the core 25 is improved, allowing for a longer replacement cycle for the first container 20 equipped with the core 25.

The first core part 251 may extend elongatedly in the horizontal direction. The first core part 251 may have a hexahedral shape. The second core part 252 may protrude above the first core part 251. The second core part 252 may extend elongatedly in the horizontal direction. The second core part 252 may have a hexahedral shape.

The first core part 251 may be larger than the second core part 252. The perimeter corresponding to the side surface 2512 of the first core part 251 may be larger than the perimeter corresponding to the side surface 2522 of the second core part 252.

The heater 2531 may be attached to the first wick part 251. The heater 2531 may be patterned on the lower surface 2513 of the first wick part 251. The heater 2531 may be patterned in various ways along the longitudinal direction of the first wick part 251. Both ends of the heater 2531 may be positioned adjacent to both ends of the first wick part 251.

A pair of first terminals 2533 may be formed on both ends of the heater 2531. The first terminals 2533 may be coupled to the underside of the first wick part 251. The pair of first terminals 2533 may be arranged adjacent to both ends of the first wick part 251. The first terminals 2533 may protrude from the underside of the first wick part 251.

The first terminal 2533 can contact the second terminal 223 to electrically connect the heater 2531 and the second terminal 223. The second terminal 223 can support the first terminal 2533 and the lower surface 2513 of the first core part 251.

Figures 8-10 are flowcharts illustrating a method of operating an aerosol generating device according to one embodiment of the present disclosure.

Referring to FIG. 8, the aerosol generating device 100 may determine whether the first container 20 is coupled to the body 10 in operation S710. For example, the aerosol generating device 100 may determine whether the body 10 and the first container 20 are coupled based on whether the power source 11 included in the body 10 and the second terminal 223 included in the first container 20 are electrically connected to each other.

In operation S720, the aerosol generating device 100 can determine whether the first container 20 and the second container 30 are combined.

Referring to FIG. 8, when the body 10 and the first container 20 are coupled together and the first container 20 and the second container 30 are then coupled together, the cartridge detection sensor 471 can output a detection signal corresponding to physical contact. Here, when the first container 20 and the second container 30 are coupled together, the body 10 and the second container 30 can also be coupled together.

On the other hand, if the first container 20 and the second container 30 are separated while the body 10 and the first container 20 are coupled together, the output of a detection signal corresponding to physical contact from the cartridge detection sensor 471 may be stopped. Here, the aerosol generating device 100 may determine that the first container 20 and the second container 30 have been separated from each other if the cartridge detection sensor 471 does not output a detection signal corresponding to physical contact.

Meanwhile, the aerosol generating device 100 may deactivate the operation of at least one component provided in the body 10, etc., when the first container 20 and/or the second container 30 are not coupled to the body 10. For example, the aerosol generating device 100 may cut off the supply of power to the heater 2531, puff sensor 461, etc., when at least one of the first container 20 and the second container 30 is not coupled to the body 10. For example, the aerosol generating device 100 may cut off the supply of power to the cartridge detection sensor 471 when the body 10 and the first container 20 are not coupled.

In operation S730, the aerosol generating device 100 may determine whether a predetermined input is received within a predetermined time when the first container 20 and the second container 30 are separated from each other while the body 10 and the first container 20 are coupled. Here, the predetermined time may be a time limit that has already been set corresponding to the cleaning function. Here, the predetermined input may correspond to a user input that has already been set to execute the cleaning function.

According to one embodiment, the aerosol generating device 100 can determine whether a predetermined input has been received based on the input received via the input/output interface 120. For example, the aerosol generating device 100 can determine that a predetermined input has been received when it receives an input of pressing a physical button a predetermined number of times. For example, the aerosol generating device 100 can determine that a predetermined input has been received when it receives a tap input of hitting the aerosol generating device 100 a predetermined number of times based on signals from an acceleration sensor and/or gyro sensor.

In operation S740, if the aerosol generating device 100 receives a predetermined input within a predetermined time, it may determine whether a predetermined condition related to the cleaning function is met. Here, the predetermined condition may correspond to the extent to which the first container 20 has been used. For example, the aerosol generating device 100 may determine that the predetermined condition is met if the cumulative number of puffs related to the cleaning function is equal to or greater than a predetermined number (e.g., 1,000 times). When the cleaning function is executed, the aerosol generating device 100 may initialize the cumulative number of puffs related to the cleaning function. Meanwhile, the predetermined number may be determined based on the number of times the cleaning function has been executed. For example, the predetermined number may decrease as the number of times the cleaning function has been executed increases.

The aerosol generating device 100 may perform a cleaning operation in operation S750 if a predetermined condition related to the cleaning function is satisfied. Here, the cleaning operation may refer to an operation of removing impurities generated by the generation of aerosol and accumulated on the wick 25. For example, the aerosol generating device 100 may supply power to the heater 2531 according to a temperature profile corresponding to the cleaning function. Here, the maximum target temperature for the heater 2531 determined by the temperature profile corresponding to the cleaning function (e.g., 300°C) may exceed the maximum target temperature for aerosol generation (e.g., 220°C).

If the aerosol generating device 100 does not receive a predetermined input within a predetermined time after the first container 20 and the second container 30 are separated from each other, it can cut off the supply of power to the heater 2531. Therefore, even if the aerosol generating device 100 receives a predetermined input to perform the cleaning function due to, for example, an unintended impact on the aerosol generating device 100 by the user, it can prevent the heater 2531 from heating.

Meanwhile, the aerosol generating device 100 may determine whether the second container 30 has been connected in operation S760. For example, the aerosol generating device 100 may determine that the first container 20 and the second container 30 have been connected when a detection signal corresponding to physical contact is output from the cartridge detection sensor 471. Here, when the first container 20 and the second container 30 are connected, the body 10 and the second container 30 may also be connected.

In operation S770, the aerosol generating device 100 can determine whether the body 10 and the first container 20 are separated from each other while the second container 30 is separated. For example, the aerosol generating device 100 can determine that the body 10 and the first container 20 are separated from each other if the power source 11 included in the body 10 and the second terminal 223 included in the first container 20 are electrically disconnected.

In operation S780, the aerosol generating device 100 may determine whether the cleaning operation is complete if the body 10 and the first container 20 are coupled and the first container 20 and the second container 30 remain separated from each other. For example, the aerosol generating device 100 may determine that the cleaning operation is complete if a predetermined time has elapsed since the cleaning operation began. The aerosol generating device 100 may supply power to the heater 2531 according to a temperature profile corresponding to the cleaning function until the cleaning operation is complete.

Figures 9a and 9b are flowcharts illustrating a method of operating an aerosol generating device according to one embodiment of the present disclosure. Detailed explanations of content that overlaps with the content described in Figures 7 and 8 will be omitted.

Referring to FIG. 9a, the aerosol generating device 100 can determine whether the body 10 and the first container 20 are coupled in operation S901.

In operation S902, the aerosol generating device 100 can determine whether the first container 20 and the second container 30 are combined.

In operation S903, the aerosol generating device 100 can determine whether a predetermined input is received within a predetermined time when the first container 20 and the second container 30 are separated from each other while the body 10 and the first container 20 are coupled.

In operation S905, the aerosol generating device 100 may perform a cleaning operation if a predetermined condition related to the cleaning function is satisfied. For example, the aerosol generating device 100 may supply power to the heater 2531 according to a first temperature profile corresponding to the cleaning function.

The aerosol generating device 100 can determine whether the second container 30 is connected in operation S906.

In operation S907, the aerosol generating device 100 can determine whether the body 10 and the first container 20 are separated from each other while the second container 30 is separated.

In operation S908, the aerosol generating device 100 may determine whether the cleaning operation is complete if the body 10 and the first container 20 are coupled and the first container 20 and the second container 30 remain separated from each other. For example, the aerosol generating device 100 may determine that the cleaning operation is complete if a predetermined first time has elapsed since the cleaning operation started. The aerosol generating device 100 may supply power to the heater 2531 according to a first temperature profile corresponding to the cleaning function until the cleaning operation is complete.

Meanwhile, referring to FIG. 9b, if a predetermined condition related to the cleaning function is not met in operation S909, the aerosol generating device 100 may determine whether the liquid has been consumed before the first container 20 and the second container 30 are separated. For example, the aerosol generating device 100 may determine that the liquid stored in the second chamber C2 has been consumed if the temperature of the heater 2531 is equal to or higher than a limit temperature while heating the heater 2531 to generate aerosol.

According to one embodiment, the aerosol generating device 100 can store in the memory 140 a history of when it is determined that the liquid has been consumed. For example, the aerosol generating device 100 can store in the memory 140 a history of when it is determined that the liquid has been consumed if the temperature of the heater 2531 is equal to or higher than a limit temperature while the heater 2531 is being heated to generate aerosol. Furthermore, the aerosol generating device 100 can determine whether the liquid has been consumed immediately before the first container 20 and the second container 30 are separated based on the history stored in the memory 140.

In operation S910, the aerosol generating device 100 may perform an operation to remove residual liquid absorbed in the wick 25 (hereinafter referred to as the residual liquid removal operation) if the liquid is not consumed before the first container 20 and the second container 30 are separated. For example, the aerosol generating device 100 may supply power to the heater 2531 according to a second temperature profile different from the first temperature profile. Here, the maximum target temperature for the heater 2531 determined by the second temperature profile (e.g., 220°C) may be less than the maximum target temperature for the heater 2531 determined by the first temperature profile (e.g., 300°C). On the other hand, the maximum target temperature for the heater 2531 determined by the second temperature profile may be different from the maximum target temperature for aerosol generation.

The aerosol generating device 100 can determine whether the second container 30 is connected in operation S911.

In operation S912, the aerosol generating device 100 can determine whether the body 10 and the first container 20 are separated from each other while the second container 30 is separated.

In operation S913, the aerosol generating device 100 can determine whether the residual liquid removal operation is complete if the body 10 and the first container 20 are connected and the first container 20 and the second container 30 remain separated from each other. For example, the aerosol generating device 100 can determine that the residual liquid removal operation is complete if a predetermined second time has elapsed since the residual liquid removal operation began.

The aerosol generating device 100 can supply power to the heater 2531 using the second temperature profile until the residual liquid removal operation is completed.

According to one embodiment, the first time corresponding to the cleaning operation and the second time corresponding to the residual liquid removal operation may be different from each other. Referring to FIG. 10 , the aerosol generating device 100 may heat the heater 2531 to a first temperature T1 from the start of the cleaning operation to a time t1 at which a first time has elapsed, based on the first temperature profile 1010. Meanwhile, the aerosol generating device 100 may heat the heater 2531 to a second temperature T2 from the start of the residual liquid removal operation to a time t2 at which a second time has elapsed, based on the second temperature profile 1020. That is, when the cleaning operation is performed, the heater 2531 may be heated to a relatively higher temperature for a relatively longer time than when the residual liquid removal operation is performed. Meanwhile, in the present disclosure, the cleaning operation is described as being performed for a longer time than the residual liquid removal operation, but this is not limiting.

The aerosol generating device 100 may supply power to the heater 2531 according to a temperature profile corresponding to the cleaning function until the cleaning operation is complete.

Meanwhile, referring to FIG. 11b, in operation S1109, the aerosol generating device 100 can determine whether a second input different from the first input is received within a predetermined time period. Here, the second input may correspond to a predetermined user input corresponding to a residual liquid removal operation. For example, the first input may correspond to an input of pressing a physical button, and the second input may correspond to an input of tapping the aerosol generating device 100. For example, the first input may correspond to an input of pressing a physical button a first number of times, and the second input may correspond to an input of pressing the physical button a second number of times.
