In this case, the components included in the aerosol-generating device 10 may be located in at least one of the main body or the cartridge.

The communication interface 11 may include at least one communication module for communication with an external device and/or a network. For example, the communication interface 11 may include a communication module for wired communication, such as a Universal Serial Bus (USB). For example, the communication interface 11 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 12 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 12 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 100. The input/output interface 12 may output information corresponding to data received from another component (or other components) of the aerosol-generating device 10 through the output device.

The aerosol-generating module 13 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 13 may include at least one heater (not shown).

The aerosol-generating module 13 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 13 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 13 may generate ultrasonic vibrations to thereby generate an aerosol from the aerosol-generating substance.

The aerosol-generating device 10 may be referred to as a cartomizer, an atomizer, or a vaporizer.

The memory 14 may store programs for processing and controlling each signal in the controller 17. The memory 14 may store processed data and data to be processed.

For example, the memory 14 may store applications designed for the purpose of performing various tasks that can be processed by the controller 17. The memory 14 may selectively provide some of the stored applications in response to the request from the controller 17.

For example, the memory 14 may store data on the operation time of the aerosol-generating device 100, the maximum number of puffs, the current number of puffs, the number of uses of battery 16, 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 14 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 15 may include at least one sensor.

For example,the sensor module 15 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 15 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 15 may include a sensor for sensing the temperature of the heater included in the aerosol-generating module 13 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 13 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 15 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 10 is formed to allow a stick to be inserted thereinto, the sensor module 15 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 10 includes a cartridge, the sensor module 15 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 15 may include a voltage sensor for sensing a voltage applied to a component (e.g. the battery 16) provided in the aerosol-generating device 10 and/or a current sensor for sensing a current.

The battery 16 may supply electric power used for the operation of the aerosol-generating device 10 under the control of the controller 17. The battery 16 may supply electric power to other components provided in the aerosol-generating device 100. For example, the battery 16 may supply electric power to the communication module included in the communication interface 11, the output device included in the input/output interface 12, and the heater included in the aerosol-generating module 13.

The battery 16 may be a rechargeable battery or a disposable battery. For example, the battery 16 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 16 is rechargeable, the charging rate (C-rate) of the battery 16 may be 10C, and the discharging rate (C-rate) thereof may be 10C to 20C. However, the present disclosure is not limited thereto. Also, for stable use, the battery 16 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 10 may further include a battery protection circuit module (PCM) (not shown), which is a circuit for protecting the battery 16. The battery protection circuit module (PCM) may be disposed adjacent to the upper surface of the battery 16. For example, in order to prevent overcharging and overdischarging of the battery 16, the battery protection circuit module (PCM) may cut off the electrical path to the battery 16 when a short circuit occurs in a circuit connected to the battery 16, when an overvoltage is applied to the battery 16, or when an overcurrent flows through the battery 16.

The aerosol-generating device 10 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 100. The aerosol-generating device 10 may charge the battery 16 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 10 may further include a power terminal (not shown) to which electric power supplied from the outside is input. For example, a power line may be connected to the power terminal, which is disposed at one side of the main body of the aerosol-generating device 100. The aerosol-generating device 10 may use the electric power supplied through the power line connected to the power terminal to charge the battery 16. In this case, the power terminal may be a wired terminal for USB communication.

The aerosol-generating device 10 may wirelessly receive electric power supplied from the outside through the communication interface 11. For example, the aerosol-generating device 10 may wirelessly receive electric power using an antenna included in the communication module for wireless communication. The aerosol-generating device 10 may charge the battery 16 using the wirelessly supplied electric power.

The controller 17 may control the overall operation of the aerosol-generating device 100. The controller 17 may be connected to each of the components provided in the aerosol-generating device 100. The controller 17 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 17 may include at least one processor. The controller 17 may control the overall operation of the aerosol-generating device 10 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 17 may perform any one of a plurality of functions of the aerosol-generating device 100. For example, the controller 17 may perform any one of a plurality of functions of the aerosol-generating device 10 (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 10 and the user's command received through the input/output interface 12.

The controller 17 may control the operation of each of the components provided in the aerosol-generating device 10 based on data stored in the memory 14. For example, the controller 17 may control the supply of a predetermined amount of electric power from the battery 16 to the aerosol-generating module 13 for a predetermined time based on the data on the temperature profile, the user's inhalation pattern, which is stored in the memory 14.

The controller 17 may determine the occurrence or non-occurrence of a puff using the puff sensor included in the sensor module 15. For example, the controller 17 may check a temperature change, a flow change, a pressure change, and a voltage change in the aerosol-generating device 10 based on the values sensed by the puff sensor. The controller 17 may determine the occurrence or non-occurrence of a puff based on the value sensed by the puff sensor.

The controller 17 may control the operation of each of the components provided in the aerosol-generating device 10 according to the occurrence or non-occurrence of a puff and/or the number of puffs. For example, the controller 17 may perform control such that the temperature of the heater is changed or maintained based on the temperature profile stored in the memory 14.

The controller 17 may perform control such that the supply of electric power to the heater is interrupted according to a predetermined condition. For example, the controller 17 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 16 is less than a predetermined value.

The controller 17 may calculate the remaining capacity with respect to the full charge capacity of the battery 16. For example, the controller 17 may calculate the remaining capacity of the battery 16 based on the values sensed by the voltage sensor and/or the current sensor included in the sensor module 15.

The controller 17 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 17 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 17 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 17 may determine a target temperature to be controlled based on the temperature profile. In this case, the controller 17 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 17 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 space into which the stick is inserted is selected in response to a command input by the user through the input/output interface 12, the controller 17 may perform control such that a predetermined amount of electric power is supplied to the heater.

FIGS. 2 to 4 are views for explaining an aerosol-generating device according to embodiments of the present disclosure.

According to various embodiments of the present disclosure, the aerosol-generating device 10 may include a main body 100 and/or a cartridge 200.

Referring to FIG. 2, the aerosol-generating device 10 according to an embodiment may include a main body 100, which is formed such that a stick 20 can be inserted into the inner space formed by a housing 101.

The stick 20 may be similar to a general combustive cigarette. For example, the stick 20 may be divided into a first portion including an aerosol generating material and a second portion including a filter and the like. Alternatively, an aerosol generating material may be included in the second portion of the stick 20. For example, a flavoring substance made in the form of granules or capsules may be inserted into the second portion.

The entire first portion is inserted into the insertion space of the aerosol-generating device 10, and the second portion may be exposed to the outside. Alternatively, only a portion of the first portion may be inserted into the insertion space of the aerosol-generating device 10, or a portion of the first portion and the second portion may be inserted. In this case, the aerosol may be generated by passing external air through the first portion, and the generated aerosol may be delivered to the user's mouth through the second portion.

The main body 100 may be structured such that external air is introduced into the main body 100 in the state in which the stick 20 is inserted thereinto. In this case, the external air introduced into the main body 100 may flow into the mouth of the user via the stick 20.

The heater may be disposed in the main body 100 at a position corresponding to the position at which the stick 20 is inserted into the main body 100. Although it is illustrated in the drawings that the heater is an electrically conductive heater 110 including a needle-shaped electrically conductive track, the present disclosure is not limited thereto.

The heater may heat the interior and/or exterior of the stick 20 using the electric power supplied from the battery 16. An aerosol may be generated from the heated stick 20. At this time, the user may hold one end of the stick 20 in the mouth to inhale the aerosol containing a tobacco material.

Meanwhile, the controller 17 may perform control such that electric power is supplied to the heater in the state in which the stick 20 is not inserted into the main body according to a predetermined condition. For example, when a cleaning function for cleaning the space into which the stick 20 is inserted is selected in response to a command input by the user through the input/output interface 12, the controller 17 may perform control such that a predetermined amount of electric power is supplied to the heater.

The controller 17 may monitor the number of puffs based on the value sensed by the puff sensor from the point in time at which the stick 20 was inserted into the main body.

When the stick 20 is removed from the main body, the controller 17 may initialize the current number of puffs stored in the memory 14.

Referring to FIG. 3, the aerosol-generating device 10 according to an embodiment may include a main body 100 and a cartridge 200. The main body 100 may support the cartridge 200, and the cartridge 200 may contain an aerosol-generating substance.

According to one embodiment, the cartridge 200 may be configured so as to be detachably mounted to the main body 100. According to another embodiment, the cartridge 200 may be integrally configured with the main body 100. For example, the cartridge 200 may be mounted to the main body 100 in a manner such that at least a portion of the cartridge 200 is inserted into the insertion space formed by a housing 101 of the main body 100.

The main body 100 may be formed to have a structure in which external air can be introduced into the main body 100 in the state in which the cartridge 200 is inserted thereinto. Here, the external air introduced into the main body 100 may flow into the user's mouth via the cartridge 200.

The controller 17 may determine whether the cartridge 200 is in a mounted state or a detached state using a cartridge detection sensor included in the sensor module 15. For example, the cartridge detection sensor may transmit a pulse current through a first terminal connected with the cartridge 200. In this case, the controller 17 may determine whether the cartridge 200 is in a connected state, based on whether the pulse current is received through a second terminal.

The cartridge 200 may include a heater 210 configured to heat the aerosol-generating substance and/or a reservoir 220 configured to contain the aerosol-generating substance. For example, a liquid delivery element impregnated with (containing) the aerosol-generating substance may be disposed inside the reservoir 220. The electrically conductive track of the heater 210 may be formed in a structure that is wound around the liquid delivery element. In this case, when the liquid delivery element is heated by the heater 210, an aerosol may be generated. Here, the liquid delivery element may include a wick made of, for example, cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

The cartridge 200 may include an insertion space 230 configured to allow the stick 20 to be inserted. For example, the cartridge 200 may include the insertion space formed by an inner wall extending in a circumferential direction along a direction in which the stick 20 is inserted. In this case, the insertion space may be formed by opening the inner side of the inner wall up and down. The stick 20 may be inserted into the insertion space formed by the inner wall.

The insertion space into which the stick 20 is inserted may be formed in a shape corresponding to the shape of a portion of the stick 20 inserted into the insertion space. For example, when the stick 20 is formed in a cylindrical shape, the insertion space may be formed in a cylindrical shape.

When the stick 20 is inserted into the insertion space, the outer surface of the stick 20 may be surrounded by the inner wall and contact the inner wall.

A portion of the stick 20 may be inserted into the insertion space, the remaining portion of the stick 20 may be exposed to the outside.

The user may inhale the aerosol while biting one end of the stick 20 with the mouth. The aerosol generated by the heater 210 may pass through the stick 20 and be delivered to the user's mouth. At this time, while the aerosol passes through the stick 20, the material contained in the stick 20 may be added to the aerosol. The material-infused aerosol may be inhaled into the user's oral cavity through the one end of the stick 20.

Referring to FIG. 4, the aerosol-generating device 10 according to an embodiment may include a main body 100 supporting the cartridge 200 and a cartridge 200 containing an aerosol-generating substance. The main body 100 may be formed so as to allow the stick 20 to be inserted into an insertion space 1300 therein.

The aerosol-generating device 10 may include a first heater for heating the aerosol-generating substance stored in the cartridge 200. For example, when the user holds one end of the stick 20 in the mouth to inhale the aerosol, the aerosol generated by the first heater may pass through the stick 20. At this time, while the aerosol passes through the stick 20, a flavor may be added to the aerosol. The aerosol containing the flavor may be drawn into the user's oral cavity through one end of the stick 20.

Alternatively, according to another embodiment, the aerosol-generating device 10 may include a first heater for heating the aerosol-generating substance stored in the cartridge 200 and a second heater for heating the stick 20 inserted into the main body 100. For example, the aerosol-generating device 10 may generate an aerosol by heating the aerosol-generating substance stored in the cartridge 200 and the stick 20 using the first heater and the second heater, respectively.

FIGS. 5 to 7 are views for explaining a stick according to embodiments of the present disclosure.

Referring to FIG. 5, the stick 20 may include a tobacco rod 21 and a filter rod 22. The first portion described above with reference to FIG. 2 may include the tobacco rod. The second portion described above with reference to FIG. 2 may include the filter rod 22.

FIG. 5 illustrates that the filter rod 22 includes a single segment. However, the filter rod 22 is not limited thereto. In other words, the filter rod 22 may include a plurality of segments. For example, the filter rod 22 may include a first segment configured to cool an aerosol and a second segment configured to filter a certain component included in the aerosol. Also, as necessary, the filter rod 22 may further include at least one segment configured to perform other functions.

A diameter of the stick 20 may be within a range of 5 mm to 9 mm, and a length of the stick 20 may be about 48 mm, but embodiments are not limited thereto. For example, a length of the tobacco rod 21 may be about 12 mm, a length of a first segment of the filter rod 22 may be about 10 mm, a length of a second segment of the filter rod 22 may be about 14 mm, and a length of a third segment of the filter rod 22 may be about 12 mm, but embodiments are not limited thereto.

The stick 20 may be wrapped using at least one wrapper 24. The wrapper 24 may have at least one hole through which external air may be introduced or internal air may be discharged. For example, the stick 20 may be wrapped using one wrapper 24. As another example, the stick 20 may be double-wrapped using at least two wrappers 24. For example, the tobacco rod 21 may be wrapped using a first wrapper 241. For example, the filter rod 22 may be wrapped using

wrappers

242, 243, 244. The tobacco rod 21 and the filter rod 22 wrapped by wrappers may be combined. The stick 20 may be re-wrapped by a single wrapper 245. When each of the tobacco rod 21 and the filter rod 22 includes a plurality of segments, each segment may be wrapped using

wrappers

242, 243, 244. The entirety of stick 20 composed of a plurality of segments wrapped by wrappers may be re-wrapped by another wrapper

The first wrapper 241 and the second wrapper 242 may be formed of general filter wrapping paper. For example, the first wrapper 241 and the second wrapper 242 may be porous wrapping paper or non-porous wrapping paper.

Furthermore, the fifth wrapper 245 may prevent the aerosol generating device 100 from being contaminated by substances formed by the stick 20. Through puffs of a user, liquid substances may be formed in the stick 20. For example, as the aerosol formed by the stick 20 is cooled by the outside air, liquid materials (e.g., moisture, etc.) may be formed. As the fifth wrapper 245 wraps the stick 20, the liquid materials formed in the stick 20 may be prevented from being leaked out of the stick 20.

The tobacco rod 21 may include an aerosol generating material. For example, the aerosol generating material may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but it is not limited thereto.

For example, the heat-conducting material may be, but is not limited to, a metal foil such as aluminum foil. For example, the heat conductive material surrounding the tobacco rod 21 may uniformly distribute heat transmitted to the tobacco rod 21, and thus, the heat conductivity applied to the tobacco rod may be increased and taste of the tobacco may be improved. Also, the heat conductive material surrounding the tobacco rod 21 may function as a susceptor heated by the induction heater. Here, although not illustrated in the drawings, the tobacco rod 21 may further include an additional susceptor, in addition to the heat conductive material surrounding the tobacco rod 21.

The PCB 1510 may be elongated vertically along the column 1400. The PCB 1510 may be a flexible printed circuit board (FPCB). The connector 1520 may be formed at one end of the PCB 1510. A plurality of light sources 1530 may be arranged on the PCB 1510. The first sensor 154 may be located at the center of the PCB 1510.

The light sources 1530 may be Light Emitting Diodes.

Accordingly, the light sources 1530 may provide uniform light to the first chamber C1.

In addition, it is possible to prevent the paths of light provided by the light sources 1530 from being blocked by the stick 40 inserted into the insertion space 2140.

The first sensor 154 may be elongated vertically along the PCB 1510. The first sensor 154 may be elongated along the first container 2100 or the insertion space 2140. The second sensor 155 may be disposed adjacent to the upper center of the PCB 1510.

The first sensor 154 may sense a change in the electromagnetic characteristics of the cartridge 200 to sense information about the cartridge 200. The first sensor 154 may sense a change in electromagnetic characteristics caused by a neighboring object. For example, when the stick 40 is inserted into the insertion space 2140 in the cartridge 200 or when there is a change in the volume of the liquid stored in the first chamber C1, the electromagnetic characteristics sensed by the first sensor 154 may change, and the first sensor 154 may measure the change to sense information about the cartridge 200.

In addition, the first sensor 154 may sense a change in the electromagnetic characteristics of the surroundings in the state of being covered by the plate 1600.

FIGs. 20 and 21 are flowcharts showing an operation method of an aerosol-generating device according to an embodiment of the present disclosure.

Referring to FIG. 20, the aerosol-generating device 10 may check a signal from the first sensor 154 and/or a signal from the second sensor 155 in operation S2010.

Referring to FIG. 21, the aerosol-generating device 10 may monitor a signal from the second sensor 155 in operation S2110. For example, the aerosol-generating device 10 may monitor a signal from the second sensor 155 in a standby mode, which is a mode that minimizes consumption of power stored in the battery 16 of the aerosol-generating device 10.

The aerosol-generating device 10 may determine whether insertion of an object into the insertion space (e.g. the insertion space 130 shown in FIG. 8) is detected by the second sensor 155 in operation S2120. For example, the aerosol-generating device 10 may determine whether the door (e.g. the door 310 shown in FIG. 8) is pivoted and located in the inner space (e.g. the inner space 131 shown in FIG. 8) using the second sensor 155.

Upon determining that an object has been inserted into the insertion space, the aerosol-generating device 10 may monitor a signal from the first sensor 154 in operation S2130. For example, upon determining that an object has been inserted into the insertion space, the aerosol-generating device 10 may supply power to the first sensor 154 to activate operation of the first sensor 154.

In this case, the aerosol-generating device 10 may check the level of the signal from the first sensor 154 while monitoring the signal from the first sensor 154. Here, the level of the signal from the first sensor 154 may refer to a value corresponding to the capacitance around the conductive body provided in the first sensor 154.

The aerosol-generating device 10 may determine whether the object inserted into the insertion space is a stick (e.g. the stick 20 shown in FIG. 9) based on the signal from the first sensor 154 in operation S2140. For example, when the level of the signal from the first sensor 154 is out of a predetermined level range, the aerosol-generating device 10 may determine that the object inserted into the insertion space is a stick. For example, when variation in the level of the signal from the first sensor 154 is equal to or greater than a predetermined threshold, the aerosol-generating device 10 may determine that the object inserted into the insertion space is a stick.

Referring back to FIG. 20, the aerosol-generating device 10 may determine whether a stick is inserted into the insertion space in operation S2020.

Upon determining that a stick has been inserted into the insertion space, the aerosol-generating device 10 may determine whether the stick inserted into the insertion space is a used stick based on the level of the signal from the first sensor 154 in operation S2030.

When the heater (e.g. the heater 115 shown in FIG. 8) is heated in the state in which a stick is inserted into the insertion space, an aerosol may be generated. The generated aerosol may be inhaled into the user's mouth via the stick. After the stick is used, components included in the aerosol, such as moisture and glycerin, may remain in the stick. For this reason, the level of the signal from the first sensor 154 when a new stick, which has not been used before, is inserted into the insertion space may differ from the level of the signal from the first sensor 154 when a used stick is inserted into the insertion space due to the components of the aerosol remaining in the stick. Accordingly, the aerosol-generating device 10 may determine whether the stick inserted into the insertion space is a used stick based on a change in the level of the signal from the first sensor 154.

For example, when variation in the level of the signal from the first sensor 154 is equal to or greater than a first threshold but less than a second threshold, the aerosol-generating device 10 may determine that the stick inserted into the insertion space is a new stick. For example, when variation in the level of the signal from the first sensor 154 is equal to or greater than the second threshold, the aerosol-generating device 10 may determine that the stick inserted into the insertion space is a used stick.

For example, the aerosol-generating device 10 may check a level range within which the level of the signal from the first sensor 154 falls with reference to a lookup table. In this case, the aerosol-generating device 10 may determine whether the stick inserted into the insertion space is a new stick based on the checked level range.

When the stick inserted into the insertion space is not a used stick, that is, when a new stick is inserted into the insertion space, the aerosol-generating device 10 may perform control such that power is supplied to the heater in operation S2040.

Upon determining that the stick inserted into the insertion space is a new stick, the aerosol-generating device 10 may deactivate the operation of the first sensor 154. For example, the aerosol-generating device 10 may interrupt the supply of power to the first sensor 154 in order to deactivate the operation of the first sensor 154.

When a stick is not inserted into the insertion space, or when the stick inserted into the insertion space is a used stick, the aerosol-generating device 10 may interrupt the supply of power to the heater in operation S2050.

Referring to FIG. 22, the level of the signal from the first sensor 154 may be observed to be a first level Lv1 in the state in which a stick is not inserted into the insertion space.

When the stick inserted into the insertion space is a new stick, which has not been used before, the level of the signal from the first sensor 154 may change to a second level Lv2. In this case, variation 2210 in the level of the signal from the first sensor 154 may be equal to or greater than the first threshold but less than the second threshold.

Meanwhile, when the stick inserted into the insertion space is a used stick, the level of the signal from the first sensor 154 may change to a third level Lv3. In this case, variation 2220 in the level of the signal from the first sensor 154 may be equal to or greater than the second threshold, which is greater than when a new stick is inserted.

That is, when the stick inserted into the insertion space is a used stick, variation in the level of the signal from the first sensor 154 may be greater than when a new stick is inserted into the insertion space due to components of the aerosol remaining in the stick, such as moisture and glycerin.

FIG. 23 is a flowchart showing an operation method of an aerosol-generating device according to another embodiment of the present disclosure. A detailed description of the same content as that described with reference to FIGs. 20 and 21 will be omitted.

Referring to FIG. 23, the aerosol-generating device 10 may detect coupling of the cartridge 200 to the body 100 using the cartridge detection sensor included in the sensor module 15 in operation S2301.

The aerosol-generating device 10 may monitor a signal from the first sensor 154 and/or a signal from the second sensor 155 in operation S2302. For example, when coupling of the cartridge 200 to the body 100 is detected, the aerosol-generating device 10 may supply power to the second sensor 155 to activate operation of the second sensor 155. For example, upon determining that an object has been inserted into the insertion space using the second sensor 155, the aerosol-generating device 10 may supply power to the first sensor 154 to activate operation of the first sensor 154.

The aerosol-generating device 10 may determine whether the object inserted into the insertion space is a stick (e.g. the stick 20 shown in FIG. 9) based on the signal from the first sensor 154 and/or the signal from the second sensor 155 in operation S2303.

Upon determining that a stick has been inserted into the insertion space, the aerosol-generating device 10 may determine whether the stick inserted into the insertion space is a used stick based on the level of the signal from the first sensor 154 in operation S2304.

When the stick inserted into the insertion space is not a used stick, that is, when a new stick is inserted into the insertion space, the aerosol-generating device 10 may perform control such that power is supplied to the heater in operation S2305. For example, the aerosol-generating device 10 may supply power to the heater based on the temperature profile stored in the memory 15.

Meanwhile, upon determining that the stick inserted into the insertion space is a new stick, the aerosol-generating device 10 may deactivate the operation of the first sensor 154.

The aerosol-generating device 10 may determine whether use of the heater ends in operation S2306. For example, the aerosol-generating device 10 may monitor the number of puffs from the time point at which the first puff was detected through the puff sensor of the sensor module 15. In this case, when the number of puffs reaches the maximum number of puffs, the aerosol-generating device 10 may determine that use of the heater has ended. For example, when the remaining charge of the battery 19 is less than a predetermined value, the aerosol-generating device 10 may determine that use of the heater has ended.

When use of the heater has not ended, the aerosol-generating device 10 may determine whether the stick is removed from the insertion space in operation S2307. The aerosol-generating device 10 may determine whether the stick is removed from the insertion space based on the signal from the second sensor 155 while the heater is being used.

When use of the heater has not ended, and when the stick is not removed from the insertion space, the aerosol-generating device 10 may continue to supply power to the heater.

Meanwhile, the aerosol-generating device 10 may interrupt the supply of power to the heater in operation S2308. For example, when the stick inserted into the insertion space is a used stick, or when use of the heater has ended after supply of power to the heater, the aerosol-generating device 10 may interrupt the supply of power to the heater.

The aerosol-generating device 10 may output a message related to interruption of the supply of power to the heater through the output device of the input/output interface 12 in operation S2309. For example, the aerosol-generating device 10 may output a message indicating that the object inserted into the insertion space is not a stick. For example, the aerosol-generating device 10 may output a message indicating that the stick inserted into the insertion space is a used stick. For example, the aerosol-generating device 10 may output a message indicating that use of the heater has ended.

In the state in which the supply of power to the heater is interrupted, the aerosol-generating device 10 may monitor whether the stick is removed from the insertion space in operation S2310.

When the stick is removed from the insertion space, the aerosol-generating device 10 may determine whether the body 100 and the cartridge 200 are separated from each other in operation S2311.

In the state in which the body 100 and the cartridge 200 are coupled to each other, the aerosol-generating device 10 may continue to monitor the signal from the first sensor 154 and/or the signal from the second sensor 155.

Meanwhile, the aerosol-generating device 10 may deactivate all of the

sensors

154 and 155 by interrupting the supply of power to the

sensors

154 and 155 in operation S2312.
