In one embodiment, the aerosol-generating device 100 may be composed only of a main body. In this case, components included in the aerosol-generating device 100 may be located in the main body. In another embodiment, the aerosol-generating device 100 may be composed of a cartridge, which contains an aerosol-generating substance, and a main body. In this case, the components included in the aerosol-generating device 100 may be located in at least one of the main body or the cartridge.

The communication interface 110 may include at least one communication module for communication with an external device and/or a network. For example, the communication interface 110 may include a communication module for wired communication, such as a Universal Serial Bus (USB). For example, the communication interface 110 may include a communication module for wireless communication, such as Wireless Fidelity (Wi-Fi), Bluetooth, Bluetooth Low Energy (BLE), ZigBee, or nearfield communication (NFC).

The input/output interface 120 may include an input device (not shown) for receiving a command from a user and/or an output device (not shown) for outputting information to the user. For example, the input device may include a touch panel, a physical button, a microphone, or the like. For example, the output device may include a display device for outputting visual information, such as a display or a light-emitting diode (LED), an audio device for outputting auditory information, such as a speaker or a buzzer, a motor for outputting tactile information such as haptic effect, or the like.

The input/output interface 120 may transmit data corresponding to a command input by the user through the input device to another component (or other components) of the aerosol-generating device 1000. The input/output interface 120 may output information corresponding to data received from another component (or other components) of the aerosol-generating device 100 through the output device.

The aerosol-generating module 130 may generate an aerosol from an aerosol-generating substance. Here, the aerosol-generating substance may be a substance in a liquid state, a solid state, or a gel state, which is capable of generating an aerosol, or a combination of two or more aerosol-generating substances.

According to an embodiment, the liquid aerosol-generating substance may be a liquid including a tobacco-containing material having a volatile tobacco flavor component. According to another embodiment, the liquid aerosol-generating substance may be a liquid including a non-tobacco material. For example, the liquid aerosol-generating substance may include water, solvents, nicotine, plant extracts, flavorings, flavoring agents, vitamin mixtures, etc.

The solid aerosol-generating substance may include a solid material based on a tobacco raw material such as a reconstituted tobacco sheet, shredded tobacco, or granulated tobacco. In addition, the solid aerosol-generating substance may include a solid material having a taste control agent and a flavoring material. For example, the taste control agent may include calcium carbonate, sodium bicarbonate, calcium oxide, etc. For example, the flavoring material may include a natural material such as herbal granules, or may include a material such as silica, zeolite, or dextrin, which includes an aroma ingredient.

In addition, the aerosol-generating substance may further include an aerosol-forming agent such as glycerin or propylene glycol.

The aerosol-generating module 130 may include at least one heater (not shown).

The aerosol-generating module 130 may include an electro-resistive heater. For example, the electro-resistive heater may include at least one electrically conductive track. The electro-resistive heater may be heated as current flows through the electrically conductive track. At this time, the aerosol-generating substance may be heated by the heated electro-resistive heater.

The electrically conductive track may include an electro-resistive material. In one example, the electrically conductive track may be formed of a metal material. In another example, the electrically conductive track may be formed of a ceramic material, carbon, a metal alloy, or a composite of a ceramic material and metal.

The electro-resistive heater may include an electrically conductive track that is formed in any of various shapes. For example, the electrically conductive track may be formed in any one of a tubular shape, a plate shape, a needle shape, a rod shape, and a coil shape.

The aerosol-generating module 130 may include a heater that uses an induction-heating method. For example, the induction heater may include an electrically conductive coil. The induction heater may generate an alternating magnetic field, which periodically changes in direction, by adjusting the current flowing through the electrically conductive coil. At this time, when the alternating magnetic field is applied to a magnetic body, energy loss may occur in the magnetic body due to eddy current loss and hysteresis loss. In addition, the lost energy may be released as thermal energy. Accordingly, the aerosol-generating substance located adjacent to the magnetic body may be heated. Here, an object that generates heat due to the magnetic field may be referred to as a susceptor.

Meanwhile, the aerosol-generating module 130 may generate ultrasonic vibrations to thereby generate an aerosol from the aerosol-generating substance.

The aerosol-generating device 100 may be referred to as a cartomizer, an atomizer, or a vaporizer.

The memory 140 may store programs for processing and controlling each signal in the controller 170. The memory 140 may store processed data and data to be processed.

For example, the memory 140 may store applications designed for the purpose of performing various tasks that can be processed by the controller 170. The memory 140 may selectively provide some of the stored applications in response to the request from the controller 170.

For example, the memory 140 may store data on the operation time of the aerosol-generating device 1000, the maximum number of puffs, the current number of puffs, the number of uses of battery 160, at least one temperature profile, the user's inhalation pattern, and data about charging/discharging. Here, "puff" means inhalation by the user. "inhalation" means the user's act of taking air or other substances into the user's oral cavity, nasal cavity, or lungs through the user's mouth or nose.

The memory 140 may include at least one of volatile memory (e.g. dynamic random access memory (DRAM), static random access memory (SRAM), or synchronous dynamic random access memory (SDRAM)), nonvolatile memory (e.g. flash memory), a hard disk drive (HDD), or a solid-state drive (SSD).

The sensor module 150 may include at least one sensor.

For example, the sensor module 150 may include a sensor for sensing a puff (hereinafter referred to as a "puff sensor"). In this case, 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, or the like.

For example, the sensor module 150 may include a sensor for sensing a puff (hereinafter referred to as a "puff sensor"). In this case, the puff sensor may be implemented by a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.

For example, the sensor module 150 may include a sensor for sensing the temperature of the heater included in the aerosol-generating module 130 and the temperature of the aerosol-generating substance (hereinafter referred to as a "temperature sensor"). In this case, the heater included in the aerosol-generating module 130 may also serve as the temperature sensor. For example, the electro-resistive material of the heater may be a material having a predetermined temperature coefficient of resistance. The sensor module 150 may measure the resistance of the heater, which varies according to the temperature, to thereby sense the temperature of the heater.

For example, in the case in which the main body of the aerosol-generating device 100 is formed to allow a stick to be inserted thereinto, the sensor module 150 may include a sensor for sensing insertion of the stick (hereinafter referred to as a "stick detection sensor").

For example, in the case in which the aerosol-generating device 100 includes a cartridge, the sensor module 150 may include a sensor for sensing mounting/demounting of the cartridge and the position of the cartridge (hereinafter referred to as a "cartridge detection sensor").

In this case, the stick detection sensor and/or the cartridge detection sensor may be implemented as an inductance-based sensor, a capacitive sensor, a resistance sensor, or a Hall sensor (or Hall IC) using a Hall effect.

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

The battery 160 may supply electric power used for the operation of the aerosol-generating device 100 under the control of the controller 170. The battery 160 may supply electric power to other components provided in the aerosol-generating device 1000. For example, the battery 160 may supply electric power to the communication module included in the communication interface 110, the output device included in the input/output interface 120, and the heater included in the aerosol-generating module 130.

The battery 160 may be a rechargeable battery or a disposable battery. For example, the battery 160 may be a lithium-ion (Li-ion) battery or a lithium polymer (Li-polymer) battery. However, the present disclosure is not limited thereto. For example, when the battery 160 is rechargeable, the charging rate (C-rate) of the battery 160 may be 100C, and the discharging rate (C-rate) thereof may be 100C to 20C. However, the present disclosure is not limited thereto. Also, for stable use, the battery 160 may be manufactured such that 80% or more of the total capacity may be ensured even when charging/discharging is performed 2000 times.

The aerosol-generating device 100 may further include a protection circuit module (PCM) (not shown), 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, in order to prevent overcharging and overdischarging 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, or when an overcurrent flows through the battery 160.

The aerosol-generating device 100 may further include a charging terminal to which electric power supplied from the outside is input. For example, the charging terminal may be formed at one side of the main body of the aerosol-generating device 1000. The aerosol-generating device 100 may charge the battery 160 using electric power supplied through the charging terminal. In this case, the charging terminal may be configured as a wired terminal for USB communication, a pogo pin, or the like.

The aerosol-generating device 100 may wirelessly receive electric power supplied from the outside through the communication interface 110. For example, the aerosol-generating device 100 may wirelessly receive electric power using an antenna included in the communication module for wireless communication. The aerosol-generating device 100 may charge the battery 160 using the wirelessly supplied electric power.

The controller 170 may control the overall operation of the aerosol-generating device 1000. The controller 170 may be connected to each of the components provided in the aerosol-generating device 1000. The controller 170 may transmit and/or receive a signal to and/or from each of the components, thereby controlling the overall operation of each of the components.

The controller 170 may include at least one processor. The controller 170 may control the overall operation of the aerosol-generating device 100 using the processor included therein. Here, the processor may be a general processor such as a central processing unit (CPU). Of course, the processor may be a dedicated device such as an application-specific integrated circuit (ASIC), or may be any of other hardware-based processors.

The controller 170 may perform any one of a plurality of functions of the aerosol-generating device 1000. For example, the controller 170 may perform any one of a plurality of functions of the aerosol-generating device 100 (e.g. a preheating function, a heating function, a charging function, and a cleaning function) according to the state of each of the components provided in the aerosol-generating device 100 and the user's command received through the input/output interface 120.

The controller 170 may control the operation of each of the components provided in the aerosol-generating device 100 based on data stored in the memory 140. For example, the controller 170 may control the supply of a predetermined amount of electric power from the battery 160 to the aerosol-generating module 130 for a predetermined time based on the data on the temperature profile, the user's inhalation pattern, which is stored in the memory 140.

The controller 170 may determine the occurrence or non-occurrence of a puff using the puff sensor included in the sensor module 150. For example, the controller 170 may check a temperature change, a flow change, a pressure change, and a voltage change in the aerosol-generating device 100 based on the values sensed by the puff sensor. The controller 170 may determine the occurrence or non-occurrence of a puff based on the value sensed by the puff sensor.

The controller 170 may control the operation of each of the components provided in the aerosol-generating device 100 according to the occurrence or non-occurrence of a puff and/or the number of puffs. For example, the controller 170 may perform control such that the temperature of the heater is changed or maintained based on the temperature profile stored in the memory 140.

The controller 170 may perform control such that the supply of electric power to the heater is interrupted according to a predetermined condition. For example, the controller 170 may perform control such that the supply of electric power to the heater is interrupted when the stick is removed, when the cartridge is demounted, when the number of puffs reaches the predetermined maximum number of puffs, when a puff is not sensed during a predetermined period of time or longer, or when the remaining capacity of the battery 160 is less than a predetermined value.

The controller 170 may calculate the remaining capacity with respect to the full charge capacity of the battery 160. For example, the controller 170 may calculate the remaining capacity of the battery 160 based on the values sensed by the voltage sensor and/or the current sensor included in the sensor module 150.

The controller 170 may perform control such that electric power is supplied to the heater using at least one of a pulse width modulation (PWM) method or a proportional-integral-differential (PID) method.

For example, the controller 170 may perform control such that a current pulse having a predetermined frequency and a predetermined duty ratio is supplied to the heater using the PWM method. In this case, the controller 170 may control the amount of electric power supplied to the heater by adjusting the frequency and the duty ratio of the current pulse.

For example, the controller 170 may determine a target temperature to be controlled based on the temperature profile. In this case, the controller 170 may control the amount of electric power supplied to the heater using the PID method, which is a feedback control method using a difference value between the temperature of the heater and the target temperature, a value obtained by integrating the difference value with respect to time, and a value obtained by differentiating the difference value with respect to time.

Although the PWM method and the PID method are described as examples of methods of controlling the supply of electric power to the heater, the present disclosure is not limited thereto, and may employ any of various control methods, such as a proportional-integral (PI) method or a proportional-differential (PD) method.

Meanwhile, the controller 170 may perform control such that electric power is supplied to the heater according to a predetermined condition. For example, when a cleaning function for cleaning the heater is selected in response to a command input by the user through the input/output interface 120, the controller 170 may perform control such that a predetermined amount of electric power is supplied to the heater.

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

The body 10 may accommodate a power source 11 (e.g., the battery 160 of FIG. 1) and a controller 12 (e.g., the controller 170 of FIG. 1). The power source 11 may supply power required for components to operate. The power source 11 may be referred to as a battery 11. The controller 12 may control the operation of the components.

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 at the first chamber C1. An upper end of the wick 25 may protrude upward of the first container 20 from the first chamber C1.

The first container 20 may include a heater 2531. The heater 2531 may be disposed at 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 be provided therein with a terminal 223. The terminal 223 may be exposed to a lower side 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 a lower container 20 or a heating module 20.

The first container 20 may have a first air flow inlet 241 formed by opening the first chamber C1. The first container 20 may have a first air flow outlet 242 formed by opening 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 20 may have an air flow discharge path (or air outflow channel) 340. Both ends 341 and 342 of the air flow discharge path 340 may be open. The air flow discharge path 340 may be partitioned from the second chamber C2. The second container 30 may be referred to as an upper container 30 or a liquid storage part 30.

mouthpiece 35 may be coupled on top of the second container 30. The mouthpiece 35 may cover an upper portion of the second container 30. The mouthpiece 35 may have a second air flow outlet 354 therein. The second air flow outlet 354 may communicate with a second end 342 of the air flow discharge path 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 10, the heater 2531 may be electrically connected to the power source 11 through the terminal 223. The heater 2531 may generate heat using power supplied from the power source 11. The heater 2531 may be a resistive heater.

The second container 30 may be coupled on top of the first container 20. The coupling of the second container 30 to the first container 20 may include that the second container 30 is directly coupled to the first container 20 and that the second container 30 is indirectly coupled to the first container 20 by being coupled to the body 10.

When the second container 30 is coupled to the first container 20, the second container 30 may supply the stored liquid to the wick 25. The wick 25 may absorb the liquid supplied from the second container 30. The heater 2531 may heat the wick 25 impregnated with the liquid to thereby generate an aerosol in the first chamber C1.

One side of the body 10 may be open to define a second air flow inlet 141. When the first container 20 is coupled to the body 10, the first air flow inlet 241 and the second air flow inlet 141 may communicate with each other. When the second container 30 is coupled to the first container 20, a first end 341 of the air flow discharge path 340 and the first air flow outlet 242 may communicate with each other. Accordingly, a flow path or channel through which air flows may be formed. A user may inhale air while holding the mouthpiece 35 in his or her mouth. When the user inhales the air, air at the outside may sequentially pass through the second air flow inlet 141, the first air flow inlet 241, the first chamber C1, the first air flow outlet 242, the air flow discharge path 340, and the second air flow outlet 354 to be delivered to the user. The air may flow along with the aerosol generated in the first chamber C1.

The puff sensor 461 may output a signal corresponding to the puff. For example, the puff sensor 461 may output a signal corresponding to an internal pressure of the aerosol generating device 100. In this case, the internal pressure of the aerosol-generating device 100 may correspond to the pressure in a flow path through which gas flows. The puff sensor 461 may be disposed at a position corresponding to the flow path through which air flows in the aerosol generating device 100. For example, the puff sensor 461 may be disposed inside the body 10 adjacent to the first air flow inlet 241.

Accordingly, the first container 20 and the second container 30 may be replaced independently of each other. For example, a consumption period of liquid stored in the second container 30 and a proper replacement period of the first container 20 may be different from each other. Only the second container 30 or the first container 20 may be individually replaced by the user. For example, a consumption period of liquid stored in the second container 30 may be shorter than a proper replacement period of the first container 20, and accordingly, the first container 20 may be replaced only once when the second container 30 is replaced several times. As a result, the first container 20 may be used longer to thereby reduce the replacement cost of the cartridge.

Referring to FIGS. 3 to 5, the first container 20 may be detachably coupled to the body 10. A first coupler 151 may allow the first container 20 and the body 10 to be detachably coupled to each other. For example, the first coupler 151 may include a hook recess 225 and a hook 125 detachably fastened to the hook recess 225. The hook 125 may be made of a material such as rubber or silicone to seal between the body 10 in the vicinity of the second air flow inlet 141 and the first container 20. As another example, the first coupler 151 may use a magnetic force to allow the first container 20 and the body 10 to be coupled to each other.

The second container 30 may be detachably coupled to the first container 20. The second container 30 may be coupled on top of the first container 20. The second container 30 may be coupled to the body 10 so as to be indirectly coupled to the first container 20. A second coupler 152 may allow the second container 30 and the body 10 to be detachably coupled to each other. For example, the second coupler 152 may include a hook recess 325 and a hook 135 detachably fastened to the hook recess 325. As another example, the second coupler 152 may use a magnetic force to allow the second container 30 and the body 10 to be coupled to each other.

The first container 20 may be detachably coupled to the body 10. The first coupler 151 may allow the first container 20 and the body 10 to be detachably coupled to each other. The second container 30 may be detachably coupled to the first container 20. The second container 30 may be coupled to the body 10 through the second coupler 152, allowing the second container 30 to be indirectly coupled to the first container 20. The second container 30 may be coupled on top of the first container 20.

When the second container 30 is coupled to the first container 20, the second container 30 may supply liquid to the wick 25. The liquid stored in the second chamber C2 may pass through the liquid outlet 314 to be absorbed by the absorbent portion 316. The absorbent portion 316 impregnated with the liquid may come into contact with the second wick part 252, so that the liquid is transferred to the second wick part 252. The liquid absorbed into the second wick part 252 may be distributed into the first wick part 251. The heater 3531 may heat the first wick part 251 impregnated with the liquid to generate an aerosol.

A film may be detachably attached to a lower surface of the absorbent portion 316. An edge of the film may be attached to a 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. A user may remove the film from the absorbent portion 316 before coupling the second container 30 to the first container 20.

The sealer 26 may seal around the liquid inlet 235 through which the wick 25 is exposed from the first chamber C1. When the second container 30 is coupled on top of the first container 20, the sealer 26 may seal between the first container 20 and the second container 30. The sealing

wall

266, 267 may protrude toward the second container 30. The sealing

wall

266, 267 may be in close contact with the second container 30. The sealing

wall

266, 267 may surround the vicinity of the liquid inlet 235. Accordingly, liquid discharged from the second container 30 may be prevented from leaking into a 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 vicinity of the first air flow outlet 242.

walls

266, 267.

The cartridge detection sensor 471 may installed in a body 10. The cartridge detection sensor 471 may sense or detect whether the second container 30 is coupled to the first container 20. Based on sensing by the cartridge detection sensor 471, the controller 12 may control the operation of various components. For example, the cartridge detection sensor 471 may be a contact sensor. The cartridge detection sensor 471 may detect 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 on the cartridge detection sensor 471 may occur. The cartridge detection sensor 471 may sense physical contact thereon. For example, the physical contact may be achieved when the cartridge detection sensor 471 comes into direct contact with the second container 30. For example, the physical contact may be achieved through an intermediate component between the cartridge detection sensor 471 and the second container 30.

A 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 movement 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 coupled together up and down. The pusher 40 may be elongated 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 (or first end) of the pusher 40 may be adjacent to the second container 30. The one end of the pusher 40 may be exposed toward the second container 30 through the one end of the pusher movement path 44. Another end (or second end) of the pusher 40 may be adjacent to the cartridge detection sensor 471. The another end of the pusher 40 may be exposed toward the cartridge detection sensor 471 through the another end of the pusher movement path 44.

For example, the pusher 40 and the pusher movement path 44 may have a shape elongated vertically. The pusher 40 may be movable up and down (or vertically). When the second container 30 is coupled on the top of the first container 20, as a lower portion 312 of the second container 30 contacts the upper end of the pusher 40 and presses the pusher 40 downward, the lower end of the pusher 40 may contact the cartridge detection sensor 471.

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

Accordingly, coupling of the second container 30 to the first container 20 may be sensed by the cartridge detection sensor 471 without an additional terminal component for electrical connection. Accordingly, the configuration of the second container 30 for sensing may be simplified to thereby reduce the manufacturing cost. In addition, when it is determined whether or not to couple to the second container 30 using a physical contact method, the influence of external noise may be small to thereby increase the sensing accuracy.

An actuator 472 may be pressed by the pusher 40, so that physical contact is transmitted or applied to the cartridge detection sensor 471. The actuator 472 may be integrally formed with the cartridge detection sensor 471. The actuator 472 may protrude long from the cartridge detection sensor 471 toward the pusher 40. The actuator 472 may provide a repulsive force to the pusher 40 in a direction away from the cartridge detection sensor 471. The actuator 472 may provide a repulsive force to the pusher 40 in a direction from the another end toward the one end of the pusher movement path 44. For example, the actuator 472 may 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 may 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 may sense physical contact. When the second container 30 is separated from the first container 20, the pusher 40 may move in a direction away from the cartridge detection sensor 471 due to the repulsive force of the actuator 472, and the pressed state of the cartridge detection sensor 471 may be released. The pusher 40 may be returned to a position before the second container 30 is coupled to the first container 20.

A sealing membrane 48 may be provided between the cartridge detection sensor 471 and the pusher movement path 44. The sealing membrane 48 may be provided between the actuator 472 and the pusher movement path 44. The sealing membrane 48 may be made of a material having elasticity to allow shape deformation. For example, the sealing membrane 48 may be made of rubber or silicone.

In an embodiment in which 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 sealing membrane 48 may be reduced in curvature or be deformed convexly toward the cartridge detection sensor 471. Accordingly, the sealing membrane 48 may prevent foreign substances, such as liquid, from leaking around the cartridge detection sensor 471 through the pusher movement path 44.

In the present disclosure, the cartridge detection sensor 471 is described as being a contact sensor, but embodiments are 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, and an eddy current proximity sensor.

According to one embodiment, whether or not the first container 20 is coupled to the body 10 may be detected by a separate sensor or by an electrical connection between the terminal 223 and the power source 11.

Referring to FIG. 6, the wick 25 may be made of a porous rigid body to absorb liquid. For example, the wick 25 may be made of a porous ceramic. The wick 25 may have greater rigidity or heat resistance than a cotton wick.

Accordingly, the wick 25 may have little or no deformation, and may be implemented in various shapes. In addition, durability of the wick 25 may be improved, and a replacement period of the first container 20 having the wick 25 may be extended.

The first wick part 251 may be elongated in one horizontal direction. The first wick part 251 may have a hexahedral shape. The second wick part 252 may protrude upward from a middle of the upper surface 2511 of the first wick part 251. The second wick part 252 may be elongated in the horizontal direction. The second wick part 252 may have a hexahedral shape.

The first wick part 251 may be larger in size than the second wick part 252. A periphery corresponding to a lateral surface 2512 of the first wick part 251 may be greater than a periphery corresponding to a lateral surface 2522 of the second wick part 252.

The heater 2531 may be attached to the first wick part 251. The heater 2531 may form a pattern on the lower surface 2513 of the first wick part 251. The heater 2531 may form various patterns along a longitudinal direction of the first wick part 251. Opposite ends of the heater 2531 may be adjacent to opposite ends of the first wick part 251.

A pair of first terminals 2533 may be provided at opposite end portions of the heater 2531. The first terminal 2533 may be coupled to the lower surface 2513 of the first wick part 251. The pair of first terminals 2533 may be adjacent to the opposite ends of the first wick part 251. The first terminal 2533 may protrude downward from the first wick part 251.

The first terminal 2533 may come into contact with the second terminal 223 to allow the heater 2531 and the second terminal 223 to be electrically connected to each other. The second terminal 223 may support the first terminal 2533 and the lower surface 2513 of the first wick part 251.

FIG. 7 is a flowchart showing an operation method of the aerosol-generating device according to an embodiment of the present disclosure.

Referring to FIG. 7, 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.

The aerosol generating device 100 may determine whether the first container 20 and the second container 30 are coupled in operation S720.

Referring to FIG. 8, when the first container 20 and the second container 30 are coupled while the body 10 and the first container 20 are coupled, the cartridge detection sensor 471 may output a detection signal corresponding to the physical contact. In this case, when the first container 20 and the second container 30 are coupled, the body 10 and the second container 30 may also be coupled.

Meanwhile, 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, output of the detection signal corresponding to the physical contact from the cartridge detection sensor 471 may be stopped. In this case, the aerosol generating device 100 may determine that the first container 20 and the second container 30 are separated when the detection signal corresponding to the physical contact is not output from the cartridge detection sensor 471.

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

The aerosol generating device 100 may determine whether a predetermined input is received within a predetermined time in operation 730, 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 this case, the predetermined time may be a predetermined time limit corresponding to the cleaning function. In this case, the predetermined input may correspond to a user input preset to execute the cleaning function.

According to an embodiment, the aerosol generating device 100 may determine whether the predetermined input is received based on an input received through the input/output interface 120. For example, the aerosol generating device 100 may determine that the predetermined input is received when an input of pressing a physical button is received a preset number of times. For example, the aerosol generating device 100 may determine that the predetermined input is received when a tap input performed by tapping the aerosol generating device 100 is received a preset number of times based on signals from the acceleration sensor and/or the gyro sensor.

The aerosol generating device 100 may determine whether a predetermined condition related to the cleaning function is satisfied in operation 740, when the predetermined input is received within the predetermined time. In this case, the predetermined condition may correspond to the degree of use of the first container 20 is used. For example, the aerosol generating device 100 may determine that the predetermined condition is satisfied when the cumulative number of puffs related to the cleaning function is equal to or greater than a predetermined number of times (e.g., 1000 times). When the cleaning function is performed, the aerosol generating device 100 may initialize the cumulative number of puffs related to the cleaning function. Meanwhile, the predetermined number of times may be determined according to the number of times the cleaning function is performed. For example, the predetermined number of times may decrease in response to an increase in the number of times the cleaning function is performed.

The aerosol generating device 100 may perform the cleaning function in operation 750, based on the satisfaction of the predetermined condition related to the cleaning function. In this case, the cleaning function may refer to an operation of removing debris accumulated in the wick 25 generated according to generating an aerosol. For example, the aerosol generating device 100 may supply power to the heater 2531 according to a temperature profile corresponding to the cleaning function. In this case, a maximum value of a target temperature for the heater 2531 determined according to the temperature profile corresponding to the cleaning function (e.g., 300°C) may exceed a maximum value of a target temperature for generating an aerosol (e.g., 220°C).

The aerosol generating device 100 may interrupt supply of power to the heater 2531 when the predetermined input is not received within the predetermined time after the first container 20 and the second container 30 are separated from each other. Accordingly, heating of the heater 2531 may be prevented even if the aerosol generating device 100 receives the predetermined input to execute the cleaning function for reasons such as an impact unrelated to the user's intention being applied to the aerosol generating device 100.

Meanwhile, the aerosol generating device 100 may determine whether the second container 30 is coupled in operation S760. For example, the aerosol generating device 100 may determine that the first container 20 and the second container 30 are coupled based on the output of the detection signal corresponding to the physical contact from the cartridge detection sensor 471. In this case, when the first container 20 and the second container 30 are coupled, the body 10 and the second container 30 may also be coupled.

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

The aerosol generating device 100 may determine whether the cleaning function is completed in operation 780, while the body 10 and the first container 20 are coupled and the first container 20 and the second container 30 are separated from each other. For example, the aerosol generating device 100 may determine that the cleaning function is completed when a predetermined time elapses from when the cleaning function starts. 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 completed.

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

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

According to an embodiment, the aerosol generating device 100 may store a history of determining that the liquid is exhausted in the memory 140. For example, the aerosol generating device 100 may store the history of determining that the liquid is exhausted in the memory 140 when the temperature of the heater 2531 is equal to or greater than the temperature limit while heating the heater 2531 to generate aerosol. In addition, the aerosol generating device 100 may determine whether the liquid is exhausted immediately before the first container 20 and the second container 30 are separated based on the history of determining that the liquid is exhausted stored in the memory 140.

When the liquid is not exhausted before the first container 20 and the second container 30 are separated, the aerosol generating device 100 may perform an operation of removing residual liquid absorbed by the wick 25 (hereinafter, operation of removing the residual liquid) 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. In this case, a maximum value of a target temperature for the heater 2531 determined according to the second temperature profile (e.g., 220°C) may be less than a maximum value of a 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 generating an aerosol.

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

The aerosol generating device 100 may determine whether the operation of removing the residual liquid is completed in operation 913, while the body 10 and the first container 20 are coupled and the first container 20 and the second container 30 are separated from each other. For example, the aerosol generating device 100 may determine that the operation of removing the residual liquid is completed when a predetermined second time elapses from when the operation of removing the residual liquid starts.

The aerosol generating device 100 may supply power to the heater 2531 according to the second temperature profile until the operation of removing the residual liquid is completed.

According to an embodiment, the first time corresponding to the cleaning function and the second time corresponding to the operation of removing the residual liquid may be different from each other. Referring to FIG. 10, the aerosol generating device 100 may heat the heater 2531 to the first temperature T1 based on the first temperature profile 1010 until t1 when the first time elapses from a point in time the cleaning function starts. Meanwhile, the aerosol generating device 100 may heat the heater 2531 to the second temperature T2 based on the second temperature profile 1010 until t2 when the second time elapses from a point in time the operation of removing the residual liquid starts. That is, when the cleaning function is performed, the heater 2531 may be heated to a relatively high temperature for a relatively long time compared to the operation of removing the residual liquid. Meanwhile, in the present disclosure, it is described that the time during which the cleaning function is performed is greater than the time during which the operation of removing the residual liquid is performed, but embodiments are not limited thereto.
