At this time, when the alternating magnetic field is applied to a magnetic material, energy loss due to eddy current loss and hysteresis loss may occur in the magnetic material. In addition, as the lost energy is released as thermal energy, an aerosol generating material adjacent to the magnetic material may be heated. Here, an object that generates heat due to the magnetic field may be named a susceptor.

[0036] Meanwhile, the aerosol generation module (130) may generate ultrasonic vibrations to generate an aerosol from an aerosol generating material.

[0037] The aerosol generating module (130) can be named a cartomizer, atomizer, vaporizer, etc.

[0038] The memory (140) can store programs for each signal processing and control within the control unit (170). The memory (140) can store data processed by the control unit (170) and data to be processed.

[0039] For example, the memory (140) can store applications designed for the purpose of performing various tasks that can be processed by the control unit (170). The memory (140) can selectively provide some of the stored applications upon request by the control unit (170).

[0040] For example, the memory (140) may store the operating time of the aerosol generator (100), the maximum number of puffs, the current number of puffs, the number of times the battery (160) is charged, the number of times the battery (160) is discharged, at least one temperature profile, data regarding the user's inhalation pattern, data regarding charging / discharging, etc. Here, a puff may refer to the user's inhalation.

[0041] The memory (140) may include at least one of volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) or non-volatile memory (e.g., flash memory, hard disk drive (HDD), solid-state drive (SSD), etc.).

[0042] The sensor module (150) may include at least one sensor.

[0043] For example, the sensor module (150) may include a sensor that detects puff (hereinafter, puff sensor). In this case, the puff sensor may be implemented by a proximity sensor such as an IR sensor, a pressure sensor, a gyroscope sensor, an accelerometer sensor, a magnetic field sensor, etc.

[0044] For example, the sensor module (150) may include a sensor (hereinafter referred to as a temperature sensor) that detects the temperature of a heater included in the aerosol generation module (130), the temperature of an aerosol generating material, etc. At this time, the heater included in the aerosol generation module (130) may perform the role of 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 varies with temperature.

[0045] 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, a stick detection sensor).

[0046] 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 mounting / detaching, position, etc. of the cartridge relative to the main body.

[0047] At this time, the stick detection sensor and / or cartridge detection sensor can be implemented by an inductance-based sensor, a capacitive sensor, a resistance sensor, a Hall sensor (Hall IC) utilizing the Hall effect, etc.

[0048] For example, the sensor module (150) may include a voltage sensor that detects a voltage applied to a component (e.g., battery (160)) provided in the aerosol generating device (100) and / or a current sensor that detects a current.

[0049] 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 provided in the aerosol generating device (100). For example, the battery (160) can supply power to a communication module included in the communication interface (110), an output device included in the input / output interface (120), a heater included in the aerosol generating module (130), etc.

[0050] The battery (160) may be a rechargeable battery or a disposable battery. For example, the battery (160) may be a lithium-ion battery or a lithium-polymer (Li-Polymer) battery, but is not limited thereto. For example, if the battery (160) is rechargeable, the charge rate (C-rate) of the battery (160) may be 10C, and the discharge rate (C-rate) may be 10C to 20C, but is not limited thereto. In addition, for stable use, the battery (160) may be manufactured so that at least 80% of the total capacity is maintained even after 2,000 charge / discharge cycles.

[0051] The aerosol generating device (100) may further include a battery protection circuit module (PCM), which is a circuit for protecting the battery (160). The battery protection module (PCM) may be positioned adjacent to the upper surface of the battery (160). For example, the battery protection module (PCM) can cut off the circuit to the battery (160) in the event that a short circuit occurs in the circuit connected to the battery (160), an overvoltage is applied to the battery (160), or an overcurrent flows through the battery (160), in order to prevent overcharging and overdischarging of the battery (160).

[0052] The aerosol generating device (100) may further include a charging terminal into which power supplied from the outside is input. For example, a charging terminal may be formed on one side of the main body of the aerosol generating device (100). The aerosol generating device (100) can charge a battery (160) using power supplied through the charging terminal. At this time, the charging terminal may be composed of a wired terminal for USB communication, a pogo pin, etc.

[0053] The aerosol generator (100) may wirelessly receive power supplied from the outside through a communication interface (110). For example, the aerosol generator (100) may receive power wirelessly by using an antenna included in a communication module for wireless communication. The aerosol generator (100) may charge a battery (160) using the wirelessly supplied power.

[0054] The control unit (170) can control the overall operation of the aerosol generating device (100). The control unit (170) can be connected to each component provided in the aerosol generating device (100). The control unit (170) can control the overall operation of each component by transmitting and / or receiving signals to and from each component.

[0055] The control unit (170) may include at least one processor. The control unit (170) may control the overall operation of the aerosol generating device (100) using the processor. 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.

[0056] 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 perform any one of the multiple functions of the aerosol generating device (100) (e.g., preheating function, heating function, charging function, cleaning function, etc.) according to the state of each component provided in the aerosol generating device (100), user commands received through the input / output interface (120), etc.

[0057] The control unit (170) can control the operation of each component provided in the aerosol generating device (100) based on data stored in the memory (140). For example, the control unit (170) can control the supply of a predetermined amount of power from the battery (160) to the aerosol generating module (130) for a predetermined amount of time based on data regarding the temperature profile, user inhalation pattern, etc., stored in the memory (140).

[0058] The control unit (170) can determine whether puffing is present through a puff sensor included in the sensor module (150). For example, the control unit (170) can check for changes in temperature, flow rate, pressure, voltage, etc. within the aerosol generating device (100) based on the sensing value of the puff sensor. The control unit (170) can determine whether puffing is present based on the results confirmed based on the sensing value of the puff sensor.

[0059] The control unit (170) can control the operation of each component provided in the aerosol generating device (100) according to whether puffing occurs and / or the number of puffs. For example, the control unit (170) can control the temperature of the heater to be changed or maintained based on a temperature profile stored in the memory (140).

[0060] The control unit (170) can control the power supply to the heater to be cut off according to predetermined conditions. For example, when the stick is removed, when 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 longer, or when the remaining capacity of the battery (160) is less than a preset value, the control unit (170) can control the power supply to the heater to be cut off.

[0061] The control unit (170) can calculate the remaining capacity of power stored in the battery (160) (hereinafter, remaining power amount). For example, the control unit (170) can calculate the remaining power amount of the battery (160) based on the sensing values ​​of the voltage sensor and / or current sensor included in the sensor module (150).

[0062] The control unit (170) can control power supply to the heater using at least one of a pulse width modulation (PWM) method and a proportional-integral-differential (PID) method.

[0063] For example, the control unit (170) can control the supply of a current pulse having a predetermined frequency and duty ratio to the heater using a PWM method. At this time, the control unit (170) can control the power supplied to the heater by adjusting the frequency and duty ratio of the current pulse.

[0064] For example, the control unit (170) can determine the target temperature that is the target of the control based on the temperature profile. At this time, the control unit (170) can control the power supplied to the heater using a PID method, which is a feedback control method using the difference value between the heater temperature and the target temperature, the value obtained by integrating the difference value over time, and the value obtained by differentiating the difference value over time.

[0065] Meanwhile, although PWM and PID methods were described as examples of control methods for supplying power to a heater, the present invention is not limited thereto, and various control methods such as Proportional-Integral (PI) and Proportional-Differential (PD) methods may be used.

[0066] Meanwhile, the control unit (170) can control power to be supplied to the heater according to preset conditions. For example, if a cleaning function that cleans the heater is selected according to a command input by a user through the input / output interface (120), the control unit (170) can control power to be supplied to the heater.

[0068] 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 mouthpiece (35) may have a second airflow outlet (354) inside. The second airflow outlet (354) may be connected to the other end (342) of the airflow discharge channel (340).

[0075] The first container (20) can be coupled to the body (10). The first container (20) can be inserted into the interior of the body (10). When the first container (20) is coupled to the body, the heater (2531) can be electrically connected to the power source (11) through the terminal (223). The heater (2531) can generate heat by receiving power from the power source (11). The heater (2531) may be a resistive heater.

[0076] The second container (30) may be coupled to the upper side of the first container (20). The coupling of the second container (30) to the first container (20) may include the second container (30) being directly coupled to the first container (20), and the second container (30) being coupled to the body (10) and indirectly coupled to the first container (20).

[0077] When the second container (30) is connected to the first container (20), the second container (30) can supply the stored liquid to the wick (25). The wick (25) can receive and absorb the liquid 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).

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 airflow path through which the gas flows. The puff sensor (461) can be placed at a location corresponding to the airflow path through which air flows in the aerosol generating device (100). For example, the puff sensor (461) can be placed inside the body (10) adjacent to the first airflow inlet (241).

[0080] 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 be different. The user may replace only the second container (30) separately or replace 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 when the second container (30) is replaced multiple times, the first container (20) may be replaced only once. Accordingly, the first container (20) can be used for a longer period, and the cost of replacing cartridges can be reduced.

[0081] Referring to FIGS. 3 through 5, the first container (20) can be detachably coupled to the body (10). The first coupler (151) can detachably couple the first container (20) and the body (10).

The film may be attached to the lower part 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 formed of a waterproof material. The film may prevent liquid from leaking from the absorbent portion (316). Before attaching the second container (30) to the first container (20), the user may detach the film from the absorbent portion (316).

[0086] The sealer (26) can seal the area around the liquid inlet (235) where the wick (25) is exposed from the first chamber (C1). When the second container (30) is attached to the upper side of the first container (20), the sealer (26) can seal the space between the first container (20) and the second container (30). The sealing walls (266, 267) can protrude toward the second container (30). The sealing walls (266, 267) can be in close contact with the second container (30). The sealing walls (266, 267) can surround the area around the liquid inlet (235). Accordingly, the liquid discharged from the second container (30) can be prevented from leaking into the gap between the first container (20) and the second container (30).

[0087] The sealer (26) may include an airflow sealing portion (268). The airflow sealing portion (268) may surround the periphery of the first airflow outlet (242). The second sealing wall (267) may protrude higher than the airflow sealing portion (268). The airflow sealing portion (268) may be formed on the outer side of the sealing walls (266, 267).

[0088] A cartridge detection sensor (471) may be installed inside the body (10). The cartridge detection sensor (471) can sense whether the second container (30) is connected to the first container (20). The control unit (12) can control the operation of various components by utilizing the sensing status of the cartridge detection sensor (471). For example, the cartridge detection sensor (471) may be a contact sensor. The cartridge detection sensor (471) can detect whether the second container (30) is connected to the first container (20) through physical contact. When the second container (30) is connected to the first container (20), physical contact may occur with the cartridge detection sensor (471). The cartridge detection sensor (471) can detect the physical contact that occurs with the cartridge detection sensor (471). For example, physical contact may occur by the cartridge detection sensor (471) coming into direct contact with the second container (30). For example, physical contact may occur through an intermediate configuration between the cartridge detection sensor (471) and the second container (30).

[0089] The pusher (40) may be positioned between the cartridge detection sensor (471) and the second container (30). The pusher (40) may be inserted into the pusher 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 joined vertically to each other. The pusher (40) may extend long 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 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 path (44). The other end of the pusher (40) may be 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 path (44).

[0090] For example, the pusher (40) and the pusher path (44) may have a shape that extends vertically. The pusher (40) may be movable vertically. When the second container (30) is coupled to the upper side of the first container (20), the lower part (312) of the second container (30) contacts the upper part of the pusher (40) and presses the pusher (40) downward, thereby allowing the lower part of the pusher (40) to come into contact with the cartridge detection sensor (471).

[0091] The cartridge detection sensor (471) can transmit a detection signal corresponding to physical contact to the control unit (12). Based on the detection signal received from the cartridge detection sensor (471), the control unit (12) can determine whether the second container (30) is coupled to the first container (20).

[0092] Accordingly, the connection status of the second container (30) can be determined by the cartridge detection sensor (471) without the second container (30) separately including a terminal configuration for electrical connection. Accordingly, the configuration of the second container (30) for sensing can be simplified, and manufacturing costs can be reduced. In addition, when determining the connection status of the second container (30) using a physical contact method, the accuracy of sensing can be improved because the influence of external noise is minimal.

[0093] The actuator (472) can be pressed by the pusher (40) to transmit physical contact to the cartridge detection sensor (471). The actuator (472) can be formed integrally with the cartridge detection sensor (471). The actuator (472) can extend long 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 one end of the pusher path (44) toward the other end. For example, the actuator (472) can provide a repulsive force that pushes the pusher (40) upward.

[0094] When the second container (30) is coupled to the first container (20), the pusher (40) can press the actuator (472) toward the cartridge detection sensor (471). When the pusher (40) presses 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). At this time, the pusher (40) can return to its position before the second container (30) was coupled to the first container (20).

[0095] A sealing film (48) may be formed between the cartridge detection sensor (471) and the pusher path (44). The sealing film (48) may be formed between the actuator (472) and the pusher path (44). The sealing film (48) may be formed of an elastic material so that its shape can be deformed. For example, the sealing film may be formed of rubber or silicone.

[0096] When the actuator (472) pushes the sealing membrane (48), the sealing membrane (48) may have a convex shape toward the pusher (40). When the pusher (40) presses the cartridge detection sensor (471), the curvature of the sealing membrane (48) may be reduced or deformed convexly toward the cartridge detection sensor (471). Accordingly, the sealing membrane (48) can prevent foreign substances, such as liquid, from leaking around the cartridge detection sensor (471) through the pusher path (44).

[0097] In the present disclosure, the cartridge detection sensor (471) is described as a contact sensor, but is not limited thereto. 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, or an eddy current proximity sensor.

[0098] According to one embodiment, whether the first container (20) is coupled to the body (10) can be detected through a separate sensor or by the electrical connection of the second terminal (223) and the power supply (11).

[0099] Referring to FIG. 6, the wick (25) can be formed from a porous rigid body that absorbs liquid. For example, the wick (25) can be formed from porous ceramic. The wick (25) may have greater rigidity or heat resistance than a cotton wick.

[0100] Accordingly, the wick (25) can be implemented in various shapes with little or no deformation of its shape. In addition, the durability of the wick (25) is improved, and the replacement cycle of the first container (20) equipped with the wick (25) can be extended.

[0101] The first wick part (251) may be extended horizontally. The first wick part (251) may have a cuboid shape. The second wick part (252) may protrude upward from the first wick part (251). The second wick part (252) may be extended horizontally. The second wick part (252) may have a cuboid shape.

[0102] The first wick part (251) may be larger than the second wick part (252). The circumference corresponding to the side (2512) of the first wick part (251) may be larger than the circumference corresponding to the side (2522) of the second wick part (252).

[0103] A heater (2531) can be attached to a first wick part (251). The heater (2531) can form a pattern on the lower surface (2513) of the first wick part (251). The heater (2531) can form various patterns along the longitudinal direction of the first wick part (251). Both ends of the heater (2531) can be adjacent to both ends of the first wick part (251).

[0104] A pair of first terminals (2533) may be formed at both ends of the heater (2531). The first terminals (2533) may be coupled to the lower surface of the first wick part (251). A pair of first terminals (2533) may be adjacent to both ends of the first wick part (251). The first terminals (2533) may protrude downward from the first wick part (251).

[0105] The first terminal (2533) is in contact with the second terminal (223) so that the heater (2531) and the second terminal (223) can be electrically connected. The second terminal (223) can support the first terminal (2533) and the lower surface (2513) of the first wick part (251).

[0106] FIG. 7 is a flowchart illustrating the operation method of an aerosol generating device according to one embodiment of the present disclosure.

[0107] Referring to FIG. 7, the aerosol generating device (100) can determine whether the body (10) and the first container (20) are coupled in operation S710. For example, the aerosol generating device (100) can 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.

[0108] The aerosol generating device (100) can determine whether the first container (20) and the second container (30) are combined in the operation of S720.

[0109] Referring to FIG. 8, when the first container (20) and the second container (30) are combined while the body (10) and the first container (20) are combined, the cartridge detection sensor (471) can output a detection signal corresponding to physical contact. At this time, when the first container (20) and the second container (30) are combined, the body (10) and the second container (30) can also be combined.

[0110] Meanwhile, when the first container (20) and the second container (30) are separated while the body (10) and the first container (20) are combined, the output of a detection signal corresponding to physical contact from the cartridge detection sensor (471) may be stopped. At this time, the aerosol generating device (100) may determine that the first container (20) and the second container (30) are separated from each other while combined, based on the fact that no detection signal corresponding to physical contact is output from the cartridge detection sensor (471).

[0111] Meanwhile, the aerosol generating device (100) may disable 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 power supply 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 power supply to the cartridge detection sensor (471) when the body (10) and the first container (20) are not coupled.

[0112] The aerosol generating device (100) can determine whether a predetermined input is received within a predetermined time based on the fact that, in operation S730, the first container (20) and the second container (30) are separated from each other while the body (10) and the first container (20) are combined. Here, the predetermined time may be a time limit set in correspondence with a cleaning function. Here, the predetermined input may correspond to a user input set in advance to execute a cleaning function.

[0113] According to one embodiment, the aerosol generating device (100) can determine whether a predetermined input is received based on an input received through an input / output interface (120). For example, the aerosol generating device (100) can determine that a predetermined input has been received if an input of pressing a physical button a preset number of times is received. For example, the aerosol generating device (100) can determine that a predetermined input has been received if a tap input of tapping the aerosol generating device (100) a preset number of times is received based on signals from an accelerometer and / or a gyroscope sensor.

[0114] The aerosol generator (100) can determine whether a predetermined condition related to the cleaning function is satisfied when a predetermined input is received within a predetermined time during operation S740. Here, the predetermined condition may correspond to the degree to which the first container (20) is used. For example, the aerosol generator (100) may determine that the predetermined condition is satisfied if the number of puffs accumulated in relation to the cleaning function is greater than a predetermined number (e.g., 1000 times). The aerosol generator (100) may reset the number of puffs accumulated in relation to the cleaning function when the cleaning function is executed. Meanwhile, the predetermined number may be determined based on the number of times the cleaning function is executed. For example, the predetermined number may decrease in correspondence with an increase in the number of times the cleaning function is executed.

[0115] The aerosol generating device (100) can perform a cleaning operation based on the fulfillment of a predetermined condition related to the cleaning function in operation S750. Here, the cleaning operation may refer to an operation to remove impurities accumulated on the wick (25) generated by the generation of aerosol. For example, the aerosol generating device (100) can supply power to the heater (2531) according to a temperature profile corresponding to the cleaning function. At this time, the maximum value of the target temperature for the heater (2531) determined according to the temperature profile corresponding to the cleaning function (e.g., 300°C) may exceed the maximum value of the target temperature for aerosol generation (e.g., 220°C).

[0116] The aerosol generating device (100) can cut off the supply of power to the heater (2531) if a predetermined input is not received within a predetermined time after the first container (20) and the second container (30) are separated from each other. Therefore, even if the aerosol generating device (100) receives a preset input to execute a cleaning function due to reasons such as an impact unrelated to the user's intention being applied to the aerosol generating device (100), heating of the heater (2531) can be prevented.

[0117] Meanwhile, the aerosol generating device (100) can determine whether the second container (30) is coupled during operation S760. For example, the aerosol generating device (100) can determine that the first container (20) and the second container (30) are coupled based on the detection signal corresponding to physical contact being output from the cartridge detection sensor (471). At this time, when the first container (20) and the second container (30) are coupled, the body (10) and the second container (30) can also be coupled.

[0118] The aerosol generating device (100) can determine whether the body (10) and the first container (20) are separated from each other in the S770 operation 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 based on the fact that the power source (11) included in the body (10) and the second terminal (223) included in the first container (20) are electrically disconnected.

[0119] The aerosol generating device (100) can determine whether the cleaning operation is completed when, in operation S780, the body (10) and the first container (20) are combined 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 cleaning operation is completed when a preset time has elapsed since the cleaning operation began. The aerosol generating device (100) can supply power to the heater (2531) according to a temperature profile corresponding to the cleaning function until the cleaning operation is completed.

[0120] FIGS. 9a and 9b are flowcharts illustrating a method of operation of an aerosol generating device according to one embodiment of the present disclosure. Detailed descriptions of contents that overlap with those described in FIGS. 7 and 8 will be omitted.

[0121] 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.

[0122] The aerosol generating device (100) can determine whether the first container (20) and the second container (30) are combined in operation S902.

[0123] The aerosol generating device (100) can determine whether a predetermined input is received within a predetermined time based on the fact that the first container (20) and the second container (30) are separated from each other while the body (10) and the first container (20) are combined in operation S903.

[0124] The aerosol generating device (100) can determine whether a predetermined condition related to a cleaning function is satisfied when a predetermined input is received within a predetermined time in operation S904.

[0125] The aerosol generating device (100) can perform a cleaning operation based on the fulfillment of a predetermined condition related to the cleaning function in operation S905. For example, the aerosol generating device (100) can supply power to a heater (2531) according to a first temperature profile corresponding to the cleaning function.

[0126] The aerosol generating device (100) can determine whether the second container (30) is combined in operation S906.

[0127] The aerosol generating device (100) can determine whether the body (10) and the first container (20) are separated from each other in the S907 operation when the second container (30) is separated.

[0128] The aerosol generating device (100) can determine whether the cleaning operation is completed when, in operation S908, the body (10) and the first container (20) are combined 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 cleaning operation is completed when a preset first time elapses from the point at which the cleaning operation is initiated. The aerosol generating device (100) can supply power to the heater (2531) according to a first temperature profile corresponding to the cleaning function until the cleaning operation is completed.

[0129] Meanwhile, referring to FIG. 9b, the aerosol generating device (100) can determine whether the liquid is depleted before the first container (20) and the second container (30) are separated, based on the fact that a predetermined condition related to the cleaning function is not satisfied in operation S909. For example, the aerosol generating device (100) can determine that the liquid stored in the second chamber (C2) is depleted if the temperature of the heater (2531) is above a limit temperature while heating the heater (2531) to generate an aerosol.

[0130] According to one embodiment, the aerosol generating device (100) may store a history in memory (140) in which the liquid is determined to be depleted. For example, the aerosol generating device (100) may store a history in memory (140) in which the liquid is determined to be depleted when the temperature of the heater (2531) is above a limit temperature while heating the heater (2531) to generate an aerosol. Additionally, the aerosol generating device (100) may determine whether the liquid is depleted just before the first container (20) and the second container (30) are separated, based on the history stored in memory (140).

[0131] The aerosol generating device (100) may perform an operation to remove residual liquid absorbed by the wick (25) (hereinafter, residual liquid removal operation) if the liquid is not depleted before the first container (20) and the second container (30) are separated in operation S910. 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. At this time, the maximum value of the target temperature for the heater (2531) determined according to the second temperature profile (e.g., 220°C) may be less than the maximum value of the target temperature for the heater (2531) determined according to the first temperature profile (e.g., 300°C). Meanwhile, the maximum value of the target temperature for the heater (2531) determined according to the second temperature profile may be different from the maximum value of the target temperature for aerosol generation.

[0132] The aerosol generating device (100) can determine whether the second container (30) is combined in operation S911.

[0133] The aerosol generating device (100) can determine whether the body (10) and the first container (20) are separated from each other in the S912 operation when the second container (30) is separated.

[0134] The aerosol generating device (100) can determine whether the residual liquid removal operation is completed when, in operation S913, the body (10) and the first container (20) are combined 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 completed when a preset second time elapses from the point in time when the residual liquid removal operation was initiated.

[0135] The aerosol generating device (100) can supply power to the heater (2531) according to the second temperature profile until the residual liquid removal operation is completed.

[0136] According to one embodiment, a first time corresponding to a cleaning operation and a second time corresponding to a 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 time when the cleaning operation is initiated until the time t1, which is the time when the first time has elapsed, based on a first temperature profile (1010). Meanwhile, the aerosol generating device (100) may heat the heater (2531) to a second temperature (T2) from the time when the residual liquid removal operation is initiated until the time t2, which is the time when the second time has elapsed, based on a second temperature profile (1020). That is, when a cleaning operation is performed, the heater (2531) may be heated to a relatively higher temperature for a relatively longer period of time compared to the residual liquid removal operation. Meanwhile, in the present disclosure, the time during which the cleaning operation is performed is described as being longer than the time during which the residual liquid removal operation is performed, but is not limited thereto.

[0137] FIGS. 11a and 11b are flowcharts illustrating a method of operation of an aerosol generating device according to one embodiment of the present disclosure. Detailed descriptions of contents that overlap with those described in FIGS. 7 to 10 will be omitted.

Here, the first input may correspond to a user input preset to execute a cleaning function.

For example, the aerosol generating device (100) can determine that the cleaning operation is completed when a preset first time elapses from the point at which the cleaning operation is initiated. The aerosol generating device (100) can supply power to the heater (2531) according to a temperature profile corresponding to the cleaning function until the cleaning operation is completed.

[0146] Meanwhile, referring to FIG. 11b, the aerosol generating device (100) can determine whether a second input different from the first input is received within a predetermined time during operation S1109. Here, the second input may correspond to a user input pre-set in response 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 a tap input of tapping the aerosol generating device (100). For example, the first input may correspond to an input of pressing the physical button a first time, and the second input may correspond to an input of pressing the physical button a second time.

[0147] The aerosol generating device (100) can determine whether the liquid is depleted before the first container (20) and the second container (30) are separated when a second input is received within a predetermined time during operation S1110.

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

[0152] As described above, according to at least one embodiment of the present disclosure, the configuration for storing liquid and the configuration including the wick (25) can be independently interchanged.

[0153] In addition, according to at least one embodiment of the present disclosure, the lifespan of the configuration including the wick (25) can be extended by removing impurities attached to the wick (25).

[0154] In addition, according to at least one embodiment of the present disclosure, liquid absorbed by the wick (25) can be removed when the configuration storing the liquid is replaced, etc.

[0155] In addition, according to at least one embodiment of the present disclosure, it is possible to prevent the heater (2531) from being heated contrary to the user's intention.

[0156] Referring to FIGS. 1 to 11b, an aerosol generating device (100) according to one aspect of the present disclosure comprises: a body (10); a first container (20) including a wick (25) and a heater (2531); a second container (30) for storing liquid; and an interface (120) for receiving user input. The device includes a control unit (170), wherein the body (10) and the first container (20) are detachably coupled to each other, and the first container (20) and the second container (30) are detachably coupled to each other, and the control unit (170) determines whether a predetermined input is received within a predetermined time corresponding to a cleaning function based on the separation between the first container (20) and the second container (30) while the body (10) and the first container (20) are coupled, and based on the reception of the predetermined input within the predetermined time, controls the supply of power to the heater (2531) according to a temperature profile corresponding to the cleaning function.

[0157] Additionally, according to another aspect of the present disclosure, the control unit (170) may control power to be supplied to the heater (2531) according to a temperature profile corresponding to the cleaning function based on the condition that a predetermined condition related to the cleaning function is satisfied when the predetermined input is received within the predetermined time, and control power to be cut off to the heater (2531) based on the condition that the predetermined condition is not satisfied.

[0158] Additionally, according to another aspect of the present disclosure, if the number of accumulated puffs in relation to the cleaning function is greater than a predetermined number, the predetermined condition may be satisfied.

[0159] Additionally, according to another aspect of the present disclosure, the control unit (170) can control the supply of power to the heater (2531) according to the temperature profile to be cut off based on the coupling between the first container (20) and the second container (30).
