[0105] Therefore, when the stick 400 is inserted into the insertion space 214, as a result of the stick stopper 217 contacting the end of the stick 400, it is possible to limit the stick 400 from moving beyond the insertion space 214 into the second chamber C2.

[0106] Also, it is possible to minimize the decrease in the amount of air flowing from the second chamber C2 into the insertion space 214.

[0107] Also, the stick stopper 217 does not prevent the aerosol generated in the second chamber C2 from extracting certain components from the medium of the stick 400.

[0108] Referring to FIGS. 10 and 11, the pivot axis or shaft 311 of the cover 310 can be disposed above the insertion space 214. The pivot axis or shaft 311 of the cover 310 can be disposed between the insertion space 214 and the insertion port 304.

When the cover 310 pivots in the second direction to close the insertion space 214, the cover 310 can contact the insertion port wall 305 to limit the movement of the cover 310.

[0114] The other end of the second guide 306 may be positioned adjacent to the insertion space 214. The other end of the second guide 306 may be positioned adjacent to the outer wall 211 of the first container 210 that constitutes the periphery of the insertion space 214. The other end of the second guide 306 may be disposed above the outer wall 211 of the first container 210 that partitions the insertion space 214. The second guide 306 may have a shape that extends obliquely from one end to the other end of the second guide 306.

[0115] Referring to FIGS. 12 to 15, the stick 400 can push the cover 310 in the inner direction of the insertion space 214 or in the first direction. When the stick 400 is inserted into the insertion space 214 while pushing the cover 310, the cover 310 may open the insertion space 214 and / or the insertion port 304.

[0116] Referring to FIGS. 12 and 13, when the end of the stick 400 passes through the insertion port 304, the end of the stick 400 can contact the insertion port wall 305. When the end of the stick 400 contacts the insertion port wall 305, the insertion port wall 305 can guide the stick 400 to a fixed position within the insertion port 304. When the stick 400 passes through the insertion port 304, the end of the stick 400 can push the cover 310 and pivot the cover 310 in the first direction.

[0117] Referring to FIGS. 13 and 14, when the stick 400 passes through the insertion port 304, the cover 310 can be inserted into the cover groove 215. The cover 310 may overlap with the inner wall 212 of the first container 210 and together with the inner wall 212 of the first container 210 can constitute one side wall of the insertion space 214.

[0118] Referring to FIGS. 14 and 15, the stick 400 can be inserted into the insertion space 214 by sliding along the surface of the cover 310. The second guide 306 can be disposed at a position facing the pivot axis of the cover 310 around the insertion port 304. The second guide 306 can be disposed at a position facing the cover groove 215. When the stick 400 is inserted into the insertion space 214, the end of the stick 400 can contact the second guide 306. When the end of the stick 400 contacts the second guide 306, the second guide 306 can guide the stick 400 to a fixed position within the insertion space 214.

When the stick 400 is inserted into the insertion space 214, the end of the stick 400 can contact the first guide 216. After the end of the stick 400 first contacts the second guide 306 and its position is guided, it can contact the first guide 216. When the end of the stick 400 contacts the first guide 216, the first guide 216 can guide the stick 400 to a fixed position within the insertion space 214.

[0120] When inserted into the insertion space 214, the end of the stick 400 can contact the stick stopper 217. By contacting the end of the stick 400, the stick stopper 217 can limit the movement of the stick 400 to the lower side of the insertion space 214 or to the second chamber C2.

[0121] Therefore, when the user pushes out the cover 310 via the stick 400, the stick 400 can be accurately guided to pass smoothly through the insertion port 304 and push out the cover 310.

[0122] Even if the stick 400 pushes out the cover 310 and the cover 310 is disposed inside the insertion space 214, the cover 310 can be received in the cover groove 215, so that the stick 400 can be in close contact with the wall partitioning the insertion space 214.

[0123] Also, by the stick 400 being in close contact with the wall partitioning the insertion space 214, when the user inhales air through the stick 400, unnecessary air flow between the insertion space 214 and the stick 400 can be prevented, reducing the wasted suction force and preventing a decrease in the efficiency of air flow.

[0124] Further, even if the user pushes out the cover 310 via the stick 400 and an external force is applied to the end of the stick 400 in the second direction by the cover 310, the stick 400 can be guided to be accurately inserted into the insertion space 214.

The connector 152 can be formed at one end of the PCB 151. A plurality of light sources 153 can be arranged on the PCB 151. The first sensor 154 can be located at the center of the PCB 151. At least one light source 153 can be arranged on both sides with the first sensor 154 in between. A plurality of light sources 153 can be arranged vertically along the PCB 151.

The light source 153 can emit light to the outside of the insertion space 214 and provide light to the first chamber C1. The light source 153 can be a Light Emitting Diode (LED).

[0138] Therefore, the light source 153 can uniformly provide light to the first chamber C1.

[0139] Also, it is possible to prevent the path of the light provided by the light source 153 from being blocked by the stick 400 inserted into the insertion space 214.

[0141] The first sensor 154 and the second sensor 155 can face the insertion space 214. The first sensor 154 can sense information about the cartridge 200.

The first sensor 154 can sense a change in the electromagnetic characteristics due to an adjacent object. For example, the first sensor 154 can be a capacitance sensor. For example, the first sensor 154 can be a magnetic proximity sensor. The type of the first sensor 154 is not limited thereto. For example, when the stick 400 is inserted into the insertion space 214 of the cartridge 200 or when a change occurs in the volume of the liquid stored in the first chamber C1, a change occurs in the electromagnetic characteristics sensed by the first sensor 154, and the first sensor 154 can measure this and sense information about the cartridge 200.

The second sensor 155 can sense a change in characteristics due to an adjacent object. For example, the second sensor 155 can be a proximity sensor. The type of the second sensor 155 is not limited thereto. For example, when the stick 400 is inserted into the insertion space 214 of the cartridge 200 or a change occurs in the volume of the liquid stored in the first chamber C1, the characteristics sensed by the second sensor 155 change, and the second sensor 155 can measure this to sense information about the cartridge 200.

[0245] In one embodiment, the aerosol generating substance in a liquid state is a liquid containing a tobacco-containing substance including a volatile tobacco flavor component, and in other embodiments, it can be a liquid containing a non-tobacco substance. For example, the aerosol generating substance in a liquid state can include water, a solvent, nicotine, a plant extract, a fragrance, a flavoring agent, a vitamin mixture, and the like.

[0246] The aerosol generating substance in a solid state can include a solid substance based on a tobacco raw material such as a reconstituted tobacco sheet, shredded tobacco, granules, etc. Further, the aerosol generating substance in a solid state can include a solid substance containing a taste regulator, a flavoring substance, etc. For example, the taste regulator can include calcium carbonate, sodium bicarbonate, calcium oxide, etc. For example, the flavoring substance can include natural substances such as herb granules, or silica, zeolite, dextrin, etc. containing a fragrance component.

[0247] Also, the aerosol generating substance can further include an aerosol former such as glycerin or propylene glycol.

[0248] The aerosol generation module 1300 can include at least one heater.

[0249] The aerosol generation module 1300 can include an electric resistance heater (for example, see heater 262 in FIG. 2). For example, the electric resistance heater can include at least one electrically conductive track and can be heated by the current flowing through the electrically conductive track. Here, the aerosol product substance can be heated by the heated electric resistance heater.

[0250] The electrically conductive track can include an electrically resistive substance. As an example, the electrically conductive track can be formed of a metallic substance. As another example, the electrically conductive track can be formed of a ceramic substance, carbon, a metal alloy, or a composite substance of a ceramic substance and a metal.

[0251] The electric resistance heater can include electrically conductive tracks formed in various shapes. For example, the electrically conductive track can be formed in any one of a tubular shape, a plate shape, a needle shape, a rod shape, and a coil shape.

[0252] The aerosol generation module 1300 can include a heater using an induction heating method. For example, the induction heating type heater can include an electrically conductive coil, and by adjusting the current flowing through the electrically conductive coil, an alternating magnetic field whose direction periodically changes can be generated. Here, when the alternating magnetic field is applied to a magnetic body, energy loss due to eddy current loss and hysteresis loss may occur in the magnetic body, and the lost energy is released as thermal energy, thereby heating the aerosol product substance adjacent to the magnetic body. Here, the object that generates heat by the magnetic field can be said to be a susceptor.

[0253] On the other hand, the aerosol generation module 1300 can also generate an aerosol from the aerosol product substance by generating ultrasonic vibrations.

[0254] The aerosol generation module 1300 can be said to be a cartomizer, an atomizer, a vaporizer, etc.

[0255] The memory 1400 can store programs for respective signal processing and control within the control unit 1700, and can store processed data and data to be processed.

[0256] For example, the memory 1400 stores application programs designed for the purpose of executing various operations processable by the control unit 1700, and can selectively provide a part of the stored application programs when requested by the control unit 1700.

[0257] For example, the memory 1400 can store data such as the operation time of the aerosol generation device 1000, the maximum puff count, the current puff count, at least one temperature profile, and the inhalation pattern of the user. Here, a puff can mean the inhalation of the user, and the inhalation can be an act of the user drawing in through the mouth or nose into the oral cavity, nasal cavity, or lungs of the user.

[0258] The memory 1400 can include at least one of a volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) and a non-volatile memory (e.g., Flash memory, Hard disk drive (HDD), Solid-state drive (SSD), etc.).

[0259] The sensor module 1500 can include at least one sensor.

[0260] For example, the sensor module 1500 can include a sensor for sensing puff (hereinafter referred to as a puff sensor), such as the third sensor 180 (see FIG. 2). Here, the puff sensor can be embodied by a proximity sensor such as an IR sensor, a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.

[0261] For example, the sensor module 1500 can include a sensor for sensing the temperature of the heater included in the aerosol generation module 1300, the temperature of the aerosol generating substance, etc. (hereinafter referred to as a temperature sensor).

[0262] Here, the heater included in the aerosol generation module 1300 can also serve as a temperature sensor. For example, the electrically resistive substance of the heater is a substance having a temperature coefficient of resistance, and the sensor module 1500 can sense the temperature of the heater by measuring the resistance of the heater that changes with temperature.

[0263] For example, when a stick can be inserted into the body 100 and / or the cartridge 200 of the aerosol generating device 1000, the sensor module 1500 can include a sensor for sensing the insertion of the stick (hereinafter referred to as a stick sensor).

[0264] For example, when the aerosol generating device 1000 includes a cartridge 200, the sensor module 1500 can include a sensor for sensing the attachment / detachment, position, etc. of the cartridge 200 to the body 100 (hereinafter referred to as a cartridge sensing sensor).

[0265] Here, the stick sensor and / or the cartridge sensing sensor can be embodied by an inductor-based sensor, a capacitance sensor, a resistance sensor, a Hall sensor using the Hall effect, or the like.

[0266] Hereinafter, the case where the stick sensor is the first sensor 154 (see FIG. 17) and / or the second sensor 155 (see FIG. 17) will be described as an example. Further, the case where the first sensor 154 is a capacitance sensor and the second sensor 155 is an optical proximity sensor will be described as an example. Further, the case where the cartridge detection sensor includes the first connection terminal 191 (see FIG. 21) will be described as an example.

[0267] For example, the sensor module 1500 can include a voltage sensor that senses a voltage applied to a configuration (for example, the battery 1600) provided in the aerosol generating device 1000 and / or a current sensor that senses a current.

[0268] The battery 1600 can supply electric power used for the operation of the aerosol generating device 1000 under the control of the control unit 1700. The battery 1600 can supply electric power to other configurations provided in the aerosol generating device 1000, for example, a communication module included in the communication interface 1100, an output device included in the input / output interface 1200, a heater included in the aerosol generation module 1300, and the like. For example, the battery 1600 can be the battery 190 housed inside the lower body 110.

[0269] The battery 1600 can be a rechargeable battery or a disposable battery. For example, the battery 1600 can be composed of, but is not limited to, a lithium ion battery, a lithium polymer (Li-Polymer) battery, a lithium iron phosphate (Lithium-ion Phosphate) battery, and the like. For example, the battery 1600 can also be composed of a lithium cobalt oxide (LiCoO 2 ) battery, a lithium titanate battery, and the like.

[0270] The aerosol generating device 1000 can further include a protection circuit module (PCM), which is a circuit for protecting the battery 1600. The protection circuit module (PCM) can be disposed adjacent to the upper surface of the battery 1600. For example, when a short circuit occurs in the circuit connected to the battery 1600, when an overvoltage is applied to the battery 1600, when an overcurrent flows through the battery 1600, etc., the protection circuit module (PCM) can cut off the circuit to the battery 1600 in order to prevent overcharging and overdischarging of the battery 1600.

[0271] The aerosol generating device 1000 can further include a charging terminal to which externally supplied power is input. For example, a charging terminal (e.g., charging port 119 (see FIG. 2)) can be formed on one side of the body 100 of the aerosol generating device 1000, and the aerosol generating device 1000 can charge the battery 1600 using the power supplied through the charging terminal. Here, the charging terminal can be composed of a wired terminal for USB communication, a pogo pin, etc.

[0272] The aerosol generating device 1000 can also wirelessly receive externally supplied power via the communication interface 1100. For example, the aerosol generating device 1000 can receive power wirelessly via an antenna included in a communication module for wireless communication, and can charge the battery 1600 using the wirelessly supplied power.

[0273] The control unit 1700 can control the overall operation of the aerosol generating device 1000. For example, the control unit 1700 can include a control device 193 housed inside the lower body 110.

[0274] The control unit 1700 is connected to each component provided in the aerosol generating device 1000, and can transmit and / or receive signals to and from each component to control the overall operation of each component.

[0275] The control unit 1700 can include at least one processor, and can control the overall operation of the aerosol generating device 1000 using the processor included therein. Here, the processor can be a general processor such as a CPU (central processing unit). Of course, the processor can be a dedicated device such as an ASIC, or a processor based on other hardware.

[0276] The control unit 1700 can perform any one of a plurality of functions of the aerosol generating device 1000. For example, the control unit 1700 can perform any one of a plurality of functions (for example, a preheating function, a heating function, a charging function, a cleaning function, etc.) of the aerosol generating device 1000 according to the state of each component provided in the aerosol generating device 1000, a user command received via the input / output interface 1200, and the like.

[0277] The control unit 1700 can control the operation of each component provided in the aerosol generating device 1000 based on the data stored in the memory 1400. For example, the control unit 1700 can control to supply a predetermined amount of power from the battery 1600 to the aerosol generation module 1300 for a predetermined period of time based on the temperature profile, data about the user's inhalation pattern, etc. stored in the memory 1400.

[0278] The control unit 1700 can determine the occurrence of a puff via the puff sensor included in the sensor module 1500. For example, the control unit 1700 can check temperature changes, flow changes, pressure changes, voltage changes, etc. within the aerosol generating device 1000 based on the sensing value of the puff sensor, and can determine the occurrence of a puff based on the checked results.

[0279] The control unit 1700 can control the operations of each component provided in the aerosol generating device 1000 according to puff occurrence and / or puff count. For example, the control unit 1700 can control to change or maintain the temperature of the heater based on the temperature profile stored in the memory 1400.

[0280] The control unit 1700 can control to cut off the power supply to the heater according to predetermined conditions. For example, when the stick 400 is removed from the insertion space 214, when the cartridge 200 is separated from the body 100, when the puff count reaches the preset maximum puff count, when no puff is detected for a time longer than the preset time, when the remaining capacity of the battery 1600 is less than a predetermined value, etc., the control unit 1700 can control to cut off the power supply to the heater.

[0281] The control unit 1700 can calculate the remaining capacity of the power stored in the battery 1600. For example, the control unit 1700 can calculate the remaining capacity of the battery 1600 based on the sensing values of the voltage sensor and / or current sensor included in the sensor module 1500.

[0282] The control unit 1700 can control to supply power to the heater by using at least one of the pulse width modulation (PWM) method and the Proportional-Integral-Differential (PID) method.

[0283] For example, the control unit 1700 can control to supply a current pulse having a predetermined frequency and duty ratio to the heater by using the PWM method. Here, the control unit 1700 can control the power supplied to the heater by adjusting the frequency and duty ratio of the current pulse.

[0284] For example, the control unit 1700 can determine a target temperature that is the target of control based on the temperature profile. Here, the control unit 1700 uses a PID method, which is a feedback control method based on the difference value between the temperature of the heater 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, to control the power supplied to the heater.

[0285] On the other hand, as an example of the control method for supplying power to the heater, the PWM method and the PID method have been described, but the present invention is not limited thereto, and various control methods such as the PI (Proportional-Integral) method and the PD (Proportional-Differential) method can be used.

[0286] FIG. 28 and FIG. 29 are flowcharts showing an operation method of an aerosol generating device according to an embodiment of the present disclosure, and FIG. 30 and FIG. 31 are diagrams for explaining the operation of the aerosol generating device according to an embodiment of the present disclosure.

[0287] Referring to FIG. 28, the aerosol generating device 1000 can monitor the signal of the capacitance sensor 154 and / or the signal of the proximity sensor 155 in operation S2810. This will be described in detail with reference to FIG. 29.

[0288] Referring to FIG. 29, the aerosol generating device 1000 can irradiate light through the sensor light source included in the proximity sensor 155 in operation S2910. Here, the light generated by the sensor light source can be irradiated toward the insertion space 214.

[0289] The aerosol generating device 1000 can monitor the signal of the photodiode included in the proximity sensor 155 in operation S2920. For example, the aerosol generating device 1000 can monitor the signal of the photodiode from the time when light is irradiated through the sensor light source.

[0290] Here, while monitoring the signal of the photodiode, the aerosol generator 1000 can check the level of the signal of the photodiode. Here, the level of the signal of the photodiode can be a value corresponding to the amount of light incident on the photodiode.

[0291] In the S2930 operation, the aerosol generator 1000 can determine whether an object is inserted into the insertion space 214 based on the signal of the photodiode. For example, the aerosol generator 1000 can determine whether an object is inserted into the insertion space 214 based on the time from when light is irradiated from the sensor light source until the photodiode reacts to the reflected light.

[0292] When no object is inserted into the insertion space 214, the light irradiated from the sensor light source toward the insertion space 214 can be reflected by the inner wall 212 of the first container 210 and incident on the photodiode. On the other hand, when an object is inserted into the insertion space 214, at least a part of the light irradiated from the sensor light source toward the insertion space 214 can be reflected by the object inserted into the insertion space 214 and incident on the photodiode before being reflected by the inner wall 212 of the first container 210. Therefore, when the time from when light is irradiated from the sensor light source until the photodiode reacts to the reflected light is less than the preset time, the aerosol generator 1000 can determine that an object is inserted into the insertion space 214.

[0293] On the other hand, when the aerosol generator 1000 includes a plurality of proximity sensors 155, for each of the plurality of proximity sensors 155, the time from when light is irradiated from the sensor light source until the photodiode reacts to the reflected light can be checked. Here, when the time checked for each of the plurality of proximity sensors 155 is less than the preset time, the aerosol generator 1000 can determine that an object is inserted into the insertion space 214.

[0294] When the aerosol generating device 1000 determines in the S2940 operation that an object has been inserted into the insertion space 214, it can monitor the signal of the capacitance sensor 154.

[0295] For example, when the aerosol generating device 1000 determines that an object has been inserted into the insertion space 214, it can supply power to the capacitance sensor 154 and monitor the signal of the capacitance sensor 154.

[0296] Here, when the aerosol generating device 1000 monitors the signal of the capacitance sensor 154, it can check the level of the signal of the capacitance sensor. Here, the level of the signal of the capacitance sensor 154 can be a value corresponding to the capacitance around the conductor provided in the capacitance sensor 154. When the stick 400 is not inserted into the insertion space 214, the level of the signal of the capacitance sensor 154 can be included in the preset level range. On the other hand, when the stick 400 is inserted into the insertion space 214, the capacitance around the conductor provided in the capacitance sensor 154 may be changed by the stick 400, and the level of the signal of the capacitance sensor 154 may also fall outside the preset level range.

[0297] In the S2950 operation, the aerosol generating device 1000 can determine whether the object inserted into the insertion space 214 is the stick 400 based on the signal of the capacitance sensor 154. For example, when the level of the signal of the capacitance sensor 154 falls outside the preset level range, the aerosol generating device 1000 can determine that the object inserted into the insertion space 214 is the stick 400. For example, when the degree of change in the level of the signal of the capacitance sensor 154 is equal to or greater than a predetermined criterion, the aerosol generating device 1000 can determine that the object inserted into the insertion space 214 is the stick 400.

[0298] On the one hand, according to an embodiment of the present disclosure, the aerosol generating device 1000 can determine whether the object inserted into the insertion space 214 is the stick 400 based on the level of the signal of the photodiode.

[0299] When the stick 400 is inserted into the insertion space 214, the stick 400 inserted into the insertion space 214 can be in close contact with the wall partitioning the insertion space 214. Here, most of the light irradiated from the sensor light source toward the insertion space 214 can be reflected by the stick 400 inserted into the insertion space 214 and incident on the photodiode.

[0300] On the other hand, when an object other than the stick 400 having a shape corresponding to the cross-section of the insertion space 214 is inserted into the insertion space 214, the object inserted into the insertion space 214 and the wall partitioning the insertion space 214 can be separated. Here, a part of the light irradiated from the sensor light source toward the insertion space 214 is reflected by the stick 400 inserted into the insertion space 214 and incident on the photodiode, and the remaining part can be irradiated toward the separation space between the object inserted into the insertion space 214 and the wall partitioning the insertion space 214.

[0301] Therefore, since the level of the signal output from the photodiode corresponds to the amount of the light incident on the photodiode, the aerosol generating device 1000 can determine whether the object inserted into the insertion space 214 is the stick 400 based on the level of the signal received from the photodiode during a predetermined time from the time when the light is irradiated from the sensor light source.

[0302] The aerosol generation device 1000 can check the level range including the level of the signal received from the photodiode based on a lookup table, and determine whether the object inserted into the insertion space 214 is the stick 400. For example, when the level range including the level of the signal received from the photodiode corresponds to the first level range, the aerosol generation device 1000 can determine that the object inserted into the insertion space 214 is not the stick 400. For example, when the level range including the level of the signal received from the photodiode corresponds to the second level range that is larger than the first level range, the aerosol generation device 1000 can determine that the object inserted into the insertion space 214 is the stick 400.

[0303] When the aerosol generation device 1000 includes a plurality of second sensors 155, for each of the plurality of second sensors 155, the level range including the level of the signal received from the photodiode can be checked, and it can be determined whether the object inserted into the insertion space 214 is the stick 400. Here, when the level ranges of all of the plurality of second sensors 155 are included in the second level range, the aerosol generation device 1000 can determine that the object inserted into the insertion space 214 is the stick 400.

[0304] On the other hand, according to an embodiment of the present disclosure, when determining whether the object inserted into the insertion space 214 is the stick 400, if the aerosol generation device 1000 determines that both the result based on the signal of the capacitance sensor 154 and the result based on the level of the signal of the photodiode are the stick 400, the aerosol generation device 1000 can also determine that the object inserted into the insertion space 214 is the stick 400.

[0305] On the one hand, according to an embodiment of the present disclosure, the aerosol generating device 1000 can also first determine information about the insertion space 214 based on the signal of the capacitance sensor 154. Here, when the aerosol generating device 1000 determines that the stick 400 is inserted into the insertion space 214 based on the signal of the capacitance sensor 154, it irradiates light through the sensor light source and can also determine information about the insertion space 214 based on the signal of the photodiode.

[0306] Also referring to FIG. 28, the aerosol generating device 1000 can determine whether the stick 400 is inserted into the insertion space 214 in operation S2820.

[0307] When it is determined in operation S2830 that the stick 400 is inserted into the insertion space 214, the aerosol generating device 1000 can determine whether the stick 400 inserted into the insertion space 214 is a used stick based on the level of the signal of the capacitance sensor 154.

[0308] When the heater 262 heats the core 261 with the stick 400 inserted into the insertion space 214, aerosol is generated in the second chamber C2, and the generated aerosol can be inhaled into the user's mouth after passing through the stick 400. Also, after using the stick 400, components such as moisture and glycerin contained in the aerosol may remain on the stick 400. Therefore, the level of the signal of the capacitance sensor 154 when a new unused stick is inserted into the insertion space 214 may be different from the level of the signal of the capacitance sensor 154 when a used stick is inserted into the insertion space 214 due to the components of the aerosol remaining inside the stick 400. Therefore, the aerosol generating device 1000 can determine whether the stick 400 inserted into the insertion space 214 is a used stick based on the change in the level of the signal of the capacitance sensor 154.

[0309] For example, when the degree of change in the level of the signal of the capacitance sensor 154 is equal to or greater than the first standard and less than the second standard, the aerosol generating device 1000 determines that the stick 400 inserted into the insertion space 214 is a new stick. When the degree of change in the level of the signal of the capacitance sensor 154 is equal to or greater than the second standard, the aerosol generating device 1000 can determine that the stick 400 inserted into the insertion space 214 is a used stick.

[0310] For example, the aerosol generating device 1000 can check the level range in which the level of the signal of the capacitance sensor 154 is included based on a lookup table, and can determine whether the stick 400 inserted into the insertion space 214 is a new stick according to the confirmed level range.

[0311] In operation S2840, when the stick 400 inserted into the insertion space 214 is not a used stick, that is, when a new stick is inserted into the insertion space 214, the aerosol generating device 1000 can be controlled to supply power to the heater 262.

[0312] In operation S2850, when no stick 400 is inserted into the insertion space 214, or when the stick 400 inserted into the insertion space 214 is a used stick, the aerosol generating device 1000 can cut off the power supply to the heater 262.

[0313] Referring to FIG. 30, the level of the signal of the capacitance sensor 154 can be monitored at the first level Lv1 before the stick 400 is inserted into the insertion space 214.

[0314] When the stick 400 inserted into the insertion space 214 is a new stick that has not been used, the level of the signal of the capacitance sensor 154 can change to the second level Lv2. Here, the degree of change 2910 in the level of the signal of the capacitance sensor 154 can be equal to or greater than the first standard and less than the second standard.

[0315] On the other hand, when the stick 400 inserted into the insertion space 214 is a used stick, the level of the signal of the capacitance sensor 154 can change to the third level Lv3. Here, the degree of change 2920 of the level of the signal of the capacitance sensor 154 can be equal to or higher than a second criterion that is larger than when a new stick is inserted.

[0316] That is, when the stick 400 inserted into the insertion space 214 is a used stick, due to components of aerosols such as moisture and glycerin remaining inside the stick 400, the degree of change in the level of the signal of the capacitance sensor 154 can be greater than when a new stick is inserted into the insertion space 214.

[0317] Referring to FIG. 31(a), the signal of the photodiode monitored from the time when light is irradiated from the sensor light source can be different between the case 2901 where the stick 400 is inserted into the insertion space 214 and the case 2902 where no object is inserted into the insertion space 214.

[0318] In the case 2901 where the stick 400 is inserted into the insertion space 214, most of the light irradiated from the sensor light source toward the insertion space 214 is reflected by the stick 400 inserted into the insertion space 214 and enters the photodiode. Therefore, when a time t1 has elapsed since the light was irradiated from the sensor light source, the photodiode can generate a signal in response to the light. On the other hand, in the case 2902 where no object is inserted into the insertion space 214, the light irradiated from the sensor light source toward the insertion space 214 is reflected by the inner wall 212 of the first container 210 and enters the photodiode. Therefore, after a time t2 longer than t1 has elapsed, the photodiode can generate a signal in response to the light.

[0319] On the other hand, referring to FIG. 31(b), the signal of the photodiode monitored from the time when light is irradiated from the sensor light source can be different between the case 2901 where the stick 400 is inserted into the insertion space 214 and the case 2912 where another object other than the stick 400 is inserted into the insertion space 214.

[0320] When another object other than the stick 400 is inserted into the insertion space 214 (case 2912), similar to the case 2901 where the stick 400 is inserted, the light irradiated from the sensor light source toward the insertion space 214 is reflected by the object inserted into the insertion space 214 and enters the photodiode. Therefore, when a time t1 elapses from the time when the light is irradiated from the sensor light source, the photodiode can generate a signal in response to the light. However, in the case 2912 where another object other than the stick 400 is inserted into the insertion space 214, only a part of the light irradiated from the sensor light source toward the insertion space 214 is reflected by the object. Therefore, the level of the signal of the photodiode confirmed after the elapse of time t1 may be smaller than that in the case 2901 where the stick 400 is inserted into the insertion space 214. Here, the smaller the area of the object on which the light is reflected, the smaller the level of the signal of the photodiode confirmed after the elapse of time t1 may be.

[0321] On the other hand, in the case 2912 where another object other than the stick 400 is inserted into the insertion space 214, a part of the light irradiated from the sensor light source toward the insertion space 214 is irradiated toward the separation space between the object inserted into the insertion space 214 and the wall partitioning the insertion space 214, and after being reflected by the wall partitioning the insertion space 214 or the like, it can be applied to the photodiode. Therefore, in the case 2912 where another object other than the stick 400 is inserted into the insertion space 214, the photodiode can generate a signal in response to the light even after a time t3 longer than t1 has elapsed. Here, the level of the signal of the photodiode confirmed after the elapse of time t3 may be smaller than the level of the signal of the photodiode confirmed after the elapse of time t1 in the case 2901 where the stick 400 is inserted into the insertion space 214.

[0322] FIG. 32 is a flowchart showing an operation method of an aerosol generating device according to another embodiment of the present disclosure. Detailed descriptions of the content overlapping with that described in FIG. 28 will be omitted.

[0323] Referring to FIG. 32, the aerosol generating device 1000 can sense the coupling of the cartridge 200 to the body 100 in operation S3201 via the cartridge sensing sensor included in the sensor module 1500. For example, the aerosol generating device 1000 can sense the coupling of the cartridge 200 to the body 100 depending on whether the first connection terminal 191 protruding outside the body 100 contacts the heater 262 of the cartridge 200.

[0324] The aerosol generating device 1000 can monitor the signal of the capacitance sensor 154 and / or the signal of the proximity sensor 155 in operation S3202. When the aerosol generating device 1000 senses the coupling of the body 100 and the cartridge 200, it can supply power from the battery 190 to the capacitance sensor 154 and / or the proximity sensor 155, and monitor the signal of the capacitance sensor 154 while the capacitance sensor 154 and / or the proximity sensor 155 is being powered.

[0325] The aerosol generating device 1000 can determine whether the stick 400 has been inserted into the insertion space 214 based on the signal of the capacitance sensor 154 and / or the signal of the proximity sensor 155 in operation S2820.

[0326] If the stick 400 is not inserted into the insertion space 214, the aerosol generating device 1000 can continuously monitor the signal of the capacitance sensor 154 and / or the proximity sensor 155.

[0327] When the aerosol generating device 1000 determines in the S3204 operation that the stick 400 has been inserted into the insertion space 214, it can determine whether the stick 400 inserted into the insertion space 214 is a used stick based on the level of the signal of the capacitance sensor 154.

[0328] When the aerosol generating device 1000 determines in the S3205 operation that the stick 400 inserted into the insertion space 214 is not a used stick, that is, when a new stick is inserted into the insertion space 214, it can supply power to the heater 262. For example, the aerosol generating device 1000 can supply power to the heater 262 based on the temperature profile stored in the memory 1500.

[0329] The aerosol generating device 1000 can determine in the S3206 operation whether the use of the heater 262 has ended. For example, the aerosol generating device 1000 can monitor the puff count from the time when the puff is first sensed through the puff sensor of the sensor module 1500, and when the puff count reaches the maximum puff count, it can be determined that the use of the heater 262 has ended. For example, the aerosol generating device 1000 can determine that the use of the heater 262 has ended when the remaining capacity of the battery 190 is less than a predetermined value.

[0330] When the aerosol generating device 1000 determines in the S3207 operation that the use of the heater 262 has not ended, it can determine whether the stick 400 is removed from the insertion space 214.

[0331] While the heater 262 is in use, the aerosol generator 1000 can irradiate light through a sensor light source and determine whether the stick 400 has been removed from the insertion space 214 based on the signal of the photodiode. For example, when the time from when the light is irradiated from the sensor light source to when the photodiode responds to the reflected light is equal to or longer than a preset time, the aerosol generator 1000 can determine that the stick 400 has been removed from the insertion space 214.

[0332] While the heater 262 is in use, the aerosol generator 1000 can determine whether the stick 400 has been removed from the insertion space 214 based on the level of the signal of the capacitance sensor 154. For example, after power is supplied to the heater 262, when the level of the signal of the capacitance sensor 154 returns to a preset level range, the aerosol generator 1000 can determine that the stick 400 has been removed from the insertion space 214. For example, after power is supplied to the heater 262, when the degree of change in the level of the signal of the capacitance sensor 154 is equal to or greater than a predetermined standard, the aerosol generator 1000 can determine that the stick 400 has been removed from the insertion space 214.

[0333] On the other hand, according to an embodiment of the present disclosure, while the heater 262 is in use, the aerosol generator 1000 can use one of the capacitance sensor 154 and the proximity sensor 155 to determine whether the stick 400 has been removed from the insertion space 214. Further, when it is determined that the stick 400 has been removed from the insertion space 214, the aerosol generator 1000 can use the other of the capacitance sensor 154 and the proximity sensor 155 to determine whether the stick 400 has been removed from the insertion space 214. Here, when it is determined that the stick 400 has been removed from the insertion space 214 based on any of the results obtained by using the capacitance sensor 154 and the proximity sensor 155, the aerosol generator 1000 can determine that the stick 400 has been removed from the insertion space 214.

[0334] If the use of the heater 262 has not ended and the stick 400 has not been removed from the insertion space 214, the aerosol generating device 1000 can continuously supply power to the heater 262.

[0335] On the other hand, in the S3208 operation, the aerosol generating device 1000 can cut off the power supply to the heater 262. For example, when the stick 400 inserted into the insertion space 214 is a used stick, or when the use of the heater 262 has ended after power is supplied to the heater 262, the aerosol generating device 1000 can cut off the power supply to the heater 262.

[0336] In the S3209 operation, the aerosol generating device 1000 can output a message regarding the cut-off of the power supply to the heater 262 via the output device of the input / output interface 1200. For example, the aerosol generating device 1000 can output a message notifying that the object inserted into the insertion space 214 is another object other than the stick 400. For example, the aerosol generating device 1000 can output a message notifying that the stick 400 inserted into the insertion space 214 is a used stick. For example, the aerosol generating device 1000 can output a message notifying that the use of the heater 262 has ended.

[0337] In the S3210 operation, the aerosol generating device 1000 can monitor whether the stick 400 is removed from the insertion space 214 while the power supply to the heater 262 is cut off.

[0338] When the aerosol generating device 1000 removes the stick 400 from the insertion space 214 in the operation of S3011, it can determine whether the body 100 and the cartridge 200 are separated. For example, when the first connection terminal 191 protruding outside the body 100 and the heater 262 of the cartridge 200 do not contact each other, the aerosol generating device 1000 can determine that the body 100 and the cartridge 200 are separated.

[0339] When the body 100 and the cartridge 200 are coupled, the aerosol generating device 1000 can continuously monitor the signals of the capacitance sensor 154 and / or the proximity sensor 155.

[0340] On the other hand, in the operation of S3012, the aerosol generating device 1000 can cut off the power supply to the plurality of sensors 154, 155 to deactivate all the plurality of sensors 154, 155.

[0341] As described above, according to at least one of the embodiments of the present disclosure, the efficiency of gas flow can be improved and the heat transfer efficiency of the aerosol to the stick 400 can be improved.

[0349] Also, according to another aspect of the present disclosure, when the time from the time when the light is irradiated from the sensor light source to the time when the photodiode reacts to the light is less than a preset time, the control unit 1700 can determine that an object is inserted into the insertion space 214.

[0350] Also, according to another aspect of the present disclosure, when the degree of change in the level of the signal received from the capacitance sensor 154 is equal to or greater than a predetermined criterion, the control unit 1700 can determine that the stick 400 is inserted into the insertion space 214.

[0351] Also, according to another aspect of the present disclosure, when the degree of change in the level of the signal received from the capacitance sensor 154 is equal to or greater than a first criterion and less than a second criterion, the control unit 1700 determines that the stick 400 inserted into the insertion space 214 is a new stick 400, and when the degree of change in the level of the signal is equal to or greater than the second criterion, the control unit 1700 can determine that the stick 400 inserted into the insertion space 214 is a used stick 400.
