The stick 400 may hang around the periphery of the stick stopper 217. The stick stopper 217 may have a shape that gradually widens toward the upper side.

[0103] Thus, when the stick 400 is inserted into the insertion space 214, the stick stopper 217 can contact the end of the stick 400 and thereby restrict the stick 400 from moving beyond the insertion space 214 into the second chamber C2.

[0104] In addition, the reduction in the amount of air flowing from the second chamber C2 into the insertion space 214 can be minimized.

[0105] Furthermore, 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.

[0106] 10 and 11, the pivot axis or shaft 311 of the cover 310 may be disposed above the insertion space 214. The pivot axis or shaft 311 of the cover 310 may be disposed between the insertion space 214 and the insertion opening 304. The cover 310 may pivot toward the inside of the insertion space 214 to open the insertion space 214 and / or the insertion opening 304. The direction in which the cover 310 pivots toward the inside of the insertion space 214 may be defined as a first direction.

[0107] When the cover 310 pivots in the first direction to open the insertion space 214, the cover 310 may be accommodated in the cover groove 215. When the cover 310 opens the insertion space 214, the cover 310 may be accommodated in the cover groove 215 and may overlap the inner wall 212 of the first container 210 located below the cover groove 215. When the cover 310 opens the insertion space 214, the cover 310 may be arranged parallel to the inner wall 212 of the first container 210 located below the cover groove 215.

[0108] The first guide 216 may be formed to be inclined from the bottom of the cover groove 215 toward the lower side of the insertion space 214. The first guide 216 may be formed to be inclined such that the insertion space 214 becomes gradually narrower as it goes downward. When the cover 310 opens the insertion space 214, the first guide 216 may be disposed adjacent to one end of the cover 310 on the lower side of the cover 310. When the cover 310 opens the insertion space 214, the first guide 216 may protrude into the insertion space 214 beyond the end of the cover 310.

[0109] The cover 310 may pivot toward the outside of the insertion space 214 to close the insertion space 214 and / or the insertion opening 304. The direction in which the cover 310 pivots toward the outside of the insertion space 214 may be defined as a second direction. One end of the spring 312 may support the cover 310, and the other end of the spring 312 may support the cap 300. The spring 312 may provide an elastic force to the cover 310 in a direction in which the cover 310 closes the insertion space 214. The cover 310 may pivot in the second direction via the spring 312.

[0110] The second guide 306 may be formed at an incline such that the inner space gradually narrows toward the lower side. The second guide 306 may be disposed adjacent to the pivot radius of the cover 310. The second guide 306 may be disposed outside the pivot radius of the cover 310. The second guide 306 may extend at an incline along the pivot radius of the cover 310.

[0111] One end of the second guide 306 may be located adjacent to the insertion opening 304. One end of the second guide 306 may be disposed outside the insertion opening 304. One end of the second guide 306 may be disposed below the insertion opening wall 305. The insertion opening wall 305 may protrude inward beyond the one end of the second guide 306. When the cover 310 pivots in the second direction to close the insertion space 214, the cover 310 can contact the insertion opening wall 305 to limit the movement of the cover 310.

[0112] The other end of the second guide 306 may be located adjacent to the insertion space 214. The other end of the second guide 306 may be located adjacent to the outer wall 211 of the first container 210 that defines the periphery of the insertion space 214. The other end of the second guide 306 may be disposed on the upper side of the outer wall 211 of the first container 210 that defines the insertion space 214. The second guide 306 may have a shape that extends obliquely from one end of the second guide 306 to the other end.

[0113] 12 to 15, the stick 400 can push the cover 310 inward or in a first direction of the insertion space 214. When the stick 400 is inserted into the insertion space 214 while pushing out the cover 310, the cover 310 can open the insertion space 214 and / or the insertion opening 304.

[0114] 12 and 13, when the end of the stick 400 passes through the insertion opening 304, the end of the stick 400 can contact the insertion opening wall 305. When the end of the stick 400 contacts the insertion opening wall 305, the insertion opening wall 305 can guide the stick 400 to a fixed position within the insertion opening 304. When the stick 400 passes through the insertion opening 304, the end of the stick 400 can push out the cover 310, causing the cover 310 to pivot in a first direction.

[0115] 13 and 14, when the stick 400 passes through the insertion opening 304, the cover 310 can be inserted into the cover groove 215. The cover 310 overlaps the inner wall 212 of the first container 210 and can form one side wall of the insertion space 214 together with the inner wall 212 of the first container 210.

[0116] 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, centered on the insertion opening 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, an end of the stick 400 can come into contact with the second guide 306. When the end of the stick 400 comes into contact with the second guide 306, the second guide 306 can guide the stick 400 to a fixed position in the insertion space 214.

[0117] The first guide 216 may be disposed at a position opposite to the second guide 306. The first guide 216 may be disposed below the second guide 216. The first guide 216 may be disposed below the cover groove 215. The first guide 216 may be disposed below the cover 310. The first guide 216 may extend in a circumferential direction along the inner wall 212 of the first container 210. When the stick 400 is inserted into the insertion space 214, the end of the stick 400 may contact the first guide 216. The end of the stick 400 may first contact the second guide 306 to be guided to a position, and then contact the first guide 216. When the end of the stick 400 contacts the first guide 216, the first guide 216 may guide the stick 400 to a fixed position in the insertion space 214.

[0118] When inserted into the insertion space 214, the end of the stick 400 can come into contact with the stick stopper 217. The stick stopper 217 can contact the end of the stick 400 to restrict the stick 400 from moving downward in the insertion space 214 or into the second chamber C2.

[0119] Therefore, when a user pushes out the cover 310 using the stick 400, the stick 400 can smoothly pass through the insertion opening 304 and be guided to a correct position so as to push out the cover 310.

[0120] In addition, even if the stick 400 pushes out the cover 310 and the cover 310 is positioned inside the insertion space 214, the cover 310 is accommodated in the cover groove 215, so that the stick 400 can adhere closely to the wall that defines the insertion space 214.

[0121] In addition, since the stick 400 is in close contact with the wall partitioning the insertion space 214, unnecessary air flow between the insertion space 214 and the stick 400 is prevented when the user inhales air through the stick 400, thereby reducing wasted suction force and preventing a decrease in the efficiency of air flow.

[0122] In addition, when the user pushes out the cover 310 through the stick 400, the cover 310 can guide the stick 400 to be accurately inserted into the insertion space 214 even if an external force is applied to the end of the stick 400 in the second direction.

[0123] In addition, the stick 400 can be restricted from moving inside the second chamber C2.

[0237] The solid-state aerosol-generating material may include solid materials based on tobacco raw materials, such as reconstituted tobacco sheets, shredded tobacco, granules, etc. The solid-state aerosol-generating material may also include solid materials containing taste modifiers, flavoring substances, etc. For example, taste modifiers may include calcium carbonate, sodium bicarbonate, calcium oxide, etc. For example, flavoring substances may include natural substances such as herb granules, or silica, zeolite, dextrin, etc., containing aroma ingredients.

[0238] Additionally, the aerosol generating material may further include an aerosol forming agent such as glycerin or propylene glycol.

[0239] The aerosol generation module 1300 can include at least one heater.

[0240] The aerosol generating module 1300 may include an electrically resistive heater (e.g., heater 262, see FIG. 2). For example, the electrically resistive heater may include at least one electrically conductive track. The electrically resistive heater may be heated by an electric current passing through the electrically conductive track. Here, the aerosol generating material may be heated by the heated electrically resistive heater.

[0241] The electrically conductive track may comprise an electrically resistive material. As an example, the electrically conductive track may be formed of a metallic material. As 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 a metal.

[0242] The electrical resistive heater may include an electrically conductive track formed in a variety of shapes, for example, the electrically conductive track may be formed in any one of a tube, a plate, a needle, a rod, and a coil.

[0243] The aerosol-generating module 1300 may include a heater using an induction heating method. For example, an induction heater may include an electrically conductive coil. The aerosol-generating module 1300 may generate an alternating magnetic field whose direction changes periodically by controlling a current flowing through the electrically conductive coil. Here, when the alternating magnetic field is applied to a magnetic material, energy loss due to eddy current loss and hysteresis loss may occur in the magnetic material. The lost energy is released as thermal energy, thereby heating the aerosol-generating material adjacent to the magnetic material. Here, the object that generates heat by the magnetic field may be called a susceptor.

[0244] On the other hand, the aerosol generating module 1300 can also generate an aerosol from an aerosol generating substance by generating ultrasonic vibrations.

[0245] The aerosol generating module 1300 may be referred to as a cartomizer, an atomizer, a vaporizer, or the like.

[0246] The memory 1400 can store programs for signal processing and control within the control unit 1700, and can store processed data and data to be processed.

[0247] For example, the memory 1400 may store application programs designed for the purpose of performing various operations processable by the controller 1700. For example, the memory 1400 may selectively provide a portion of the stored application programs upon request of the controller 1700.

[0248] For example, the memory 1400 may store data on the operation time of the aerosol generating device 1000, the maximum number of puffs, the current number of puffs, at least one temperature profile, data on the inhalation pattern of the user, etc. Here, the puff may refer to the inhalation of the user. Inhalation may be an act of the user drawing air into the oral cavity, nasal cavity, or lungs through the mouth or nose.

[0249] The memory 1400 may include at least one of a volatile memory (e.g., DRAM, SRAM, SDRAM, etc.), a non-volatile memory (e.g., flash memory, a hard disk drive (HDD), a solid-state drive (SSD), etc.).

[0250] The memory 1400 may be disposed in at least one of the body 100, the cartridge 200, and the cap 300. The memory 1400 may be disposed in each of the body 100 and the cartridge 200. For example, the memory of the body 100 may store information about a configuration disposed inside the body 100, such as information about the total capacity of the battery 190, and the memory of the cartridge 200 may store information about a configuration disposed inside the cartridge 200, such as information about the resistance value of the heater 262.

[0251] The sensor module 1500 can include at least one sensor.

[0252] For example, the sensor module 1500 may include a sensor for detecting a puff (hereinafter, referred to as a puff sensor), for example, the second sensor 180 (see FIG. 2). Here, the puff sensor may be implemented 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.

[0253] For example, the sensor module 1500 may include a sensor (hereinafter, referred to as a temperature sensor) that detects the temperature of the heater 262 included in the aerosol generation module 1300, the temperature of the aerosol generation material, etc.

[0254] Here, the heater 262 included in the aerosol generation module 1300 may also function as a temperature sensor. For example, the electrically resistive material of the heater 262 may be a material having a temperature coefficient of resistance. For example, the sensor module 1500 may sense the temperature of the heater 262 by measuring the resistance of the heater 262, which changes depending on the temperature.

[0255] For example, if a stick can be inserted into the body 100 and / or cartridge 200 of the aerosol generating device 1000, the sensor module 1500 may include a sensor that detects the insertion of a stick (hereinafter referred to as a stick sensor).

[0256] For example, in the case where the aerosol generating device 1000 includes the cartridge 200, the sensor module 1500 may include a sensor (hereinafter, referred to as a cartridge detection sensor) that detects the attachment / detachment, position, etc. of the cartridge 200 relative to the body 100.

[0257] Here, the stick sensor and / or cartridge detection sensor may be implemented using an inductance-based sensor, a capacitance sensor, a resistance sensor, a Hall sensor using the Hall effect, etc. According to an embodiment of the present invention, the first sensor 154 (see FIG. 17) may be configured as a stick detection sensor. Meanwhile, according to an embodiment of the present invention, the cartridge detection sensor may include a first connection terminal 191 (see FIG. 21).

[0258] For example, the sensor module 1500 may include a voltage sensor that detects the voltage applied to a component (e.g., battery 1600) provided in the aerosol generating device 1000 and / or a current sensor that detects the current.

[0259] For example, the sensor module 1500 may include at least one sensor (hereinafter, referred to as a contact sensor) that detects contact by an object. Here, the contact sensor may be implemented as at least one of a force sensor that outputs a signal corresponding to the magnitude of force applied by contact and a touch sensor that outputs a signal corresponding to a state change caused by contact. For example, the touch sensor may be, but is not limited to, a capacitive touch sensor, a resistive touch sensor, a surface acoustic wave touch sensor, an infrared touch sensor, or the like.

[0260] The battery 1600 may supply power used for the operation of the aerosol generating device 1000 under the control of the control unit 1700. The battery 1600 may supply power to other components provided in the aerosol generating device 1000, such as a communication module included in the communication interface 1100, an output device included in the input / output interface 1200, and a heater 262 included in the aerosol generating module 1300. For example, the battery 1600 may be the battery 190 housed inside the lower body 110.

[0261] The battery 1600 may be a rechargeable battery or a disposable battery. For example, the battery 1600 may be a lithium-ion battery, a lithium-polymer battery, a lithium-ion phosphate battery, etc., but the present disclosure is not limited thereto. For example, the battery 1600 may be a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, etc.

[0262] The aerosol generating device 1000 may further include a battery protection circuit module (PCM) which is a circuit for protecting the battery 1600. The battery protection module (PCM) may be disposed adjacent to an upper surface of the battery 1600. For example, in order to prevent overcharging and overdischarging of the battery 1600, the battery protection module (PCM) may cut off an electric path to the battery 1600 when a short circuit occurs in a circuit connected to the battery 1600, when an overvoltage is applied to the battery 1600, when an overcurrent flows through the battery 1600, etc.

[0263] The aerosol generating device 1000 may further include a charging terminal to which power supplied from an external source is input. For example, a charging terminal (e.g., a charging port 119 (see FIG. 2)) may be formed on one side of the body 100 of the aerosol generating device 1000. The aerosol generating device 1000 may charge the battery 1600 using the power supplied through the charging terminal. Here, the charging terminal may be a wired terminal for USB communication, a pogo pin, or the like.

[0264] The aerosol generating device 1000 can also wirelessly receive power supplied from an external source 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. For example, the aerosol generating device can charge the battery 1600 using the wirelessly supplied power.

[0265] 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.

[0266] The control unit 1700 may be connected to each component included in the aerosol generating device 1000. The control unit 1700 may transmit and / or receive signals between each component to control the overall operation of each component.

[0267] The control unit 1700 may include at least one processor. The control unit 1700 may use the processor to control the overall operation of the aerosol generating device 1000. 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 ASIC, or a processor based on other hardware.

[0268] The control unit 1700 can achieve any one of a plurality of functions of the aerosol generating device 1000. For example, the control unit 1700 can achieve any one of a plurality of functions of the aerosol generating device 1000 (e.g., a preheating function, a heating function, a charging function, a cleaning function, etc.) according to the state of each component included in the aerosol generating device 1000, a user's command received via the input / output interface 1200, etc.

[0269] The control unit 1700 can control the operation of each component included in the aerosol generating device 1000 based on the data stored in the memory 1400. For example, the control unit 1700 can control the battery 1600 to supply a predetermined amount of power to the aerosol generating module 1300 for a predetermined period of time based on data about a temperature profile, a user's inhalation pattern, etc. stored in the memory 1400.

[0270] The control unit 1700 may determine the occurrence of a puff through a puff sensor included in the sensor module 1500. For example, the control unit 1700 may check a temperature change, a flow change, a pressure change, a voltage change, etc. in the aerosol generating device 1000 based on a sensing value of the puff sensor, and may determine the occurrence of a puff based on the checked result.

[0271] The control unit 1700 can control the operation of each component included in the aerosol generating device 1000 according to the occurrence of puffs and / or the number of puffs. For example, the control unit 1700 can control the heater 262 to change or maintain the temperature based on the temperature profile stored in the memory 1400.

[0272] The control unit 1700 may control to cut off the power supply to the heater 262 according to a predetermined condition. For example, the control unit 1700 may control to cut off the power supply to the heater 262 when the stick 400 is removed from the insertion space 214, when the cartridge 200 is separated from the body 100, when the number of puffs reaches a predetermined maximum number of puffs, when no puffs are detected for a predetermined time or more, when the remaining capacity of the battery 1600 is less than a predetermined value, etc.

[0273] The control unit 1700 may calculate the remaining capacity of the power stored in the battery 1600. For example, the control unit 1700 may calculate the remaining capacity of the battery 1600 based on the sensing values ​​of a voltage sensor and / or a current sensor included in the sensor module 1500.

[0274] The control unit 1700 may control the supply of power to the heater 262 using at least one of a pulse width modulation (PWM) method and a proportional-integral-differential (PID) method.

[0275] For example, the control unit 1700 may use a PWM method to control the supply of a current pulse having a predetermined frequency and duty ratio to the heater 262. Here, the control unit 1700 may control the power supplied to the heater 262 by adjusting the frequency and duty ratio of the current pulse.

[0276] For example, the control unit 1700 can determine a target temperature to be a control target based on the temperature profile. Here, the control unit 1700 can control the power supplied to the heater 262 using a PID method, which is a feedback control method based on a difference between the temperature of the heater 262 and the target temperature, a value obtained by integrating the difference over time, and a value obtained by differentiating the difference over time.

[0277] Meanwhile, the PWM method and the PID method have been described as examples of control methods for supplying power to the heater 262, but the present invention is not limited to these, and various control methods such as the PI (Proportional-Integral) method and the PD (Proportional-Differential) method can be used.

[0278] FIG. 28 is a flowchart showing an operation method of the aerosol generation device according to one embodiment of the present invention. Hereinafter, the directions of the aerosol generation device 1000 can be defined based on the Cartesian coordinate system shown in FIGS. 29 to 36. In the Cartesian coordinate system, the x-axis direction can be defined as the left-right direction of the aerosol generation device. Here, based on the origin, the +x direction can be the right direction, and the -x direction can be the left direction. The y-axis direction can be defined as the front-rear direction of the aerosol generation device 1000. Here, based on the origin, the +y direction can be the front direction, and the -y direction can be the rear direction. The z-axis direction can be defined as the up-down direction of the aerosol generation device 1000. Based on the origin, the +z direction can be the upward direction, and the -z direction can be the downward direction.

[0279] 28, the aerosol generating device 1000 may check whether predetermined data for user authentication (hereinafter, referred to as authentication data) is stored in the memory 1400 in operation S2801. Here, the authentication data may include a signal pattern of a contact sensor included in the sensor module 1500 (hereinafter, referred to as a first authentication pattern) and / or a signal pattern of a button included in the input / output interface 1200 (hereinafter, referred to as a second authentication pattern) corresponding to a user who has the right to use the aerosol generating device 1000.

[0280] The aerosol generating device 1000 can monitor a signal from an input device if authentication data is stored in the memory 1400 in operation S2802.

[0281] For example, the aerosol generating device 1000 may determine whether or not a predetermined object has been touched based on a signal from a force sensor and / or a touch sensor. Here, the predetermined object may be an object corresponding to a user's body. Meanwhile, the touch of the predetermined object may be referred to as a user's touch input.

[0282] For example, the aerosol generating device 1000 can determine whether it receives a button press input based on a button signal. Meanwhile, the button press input can be referred to as a user push input.

[0283] In operation S2803, the aerosol generating device 1000 can determine whether the signal from the input device is a signal corresponding to authentication data.

[0284] For example, the first authentication pattern included in the authentication data may be at least one of the number of times an object contacts, the time when the object contacts, the time interval between the time points when the object contacts, and the change in the position where the object contacts. Here, the aerosol generating device 1000 may determine whether the touch input pattern detected by the signal of the contact sensor corresponds to the first authentication pattern.

[0285] For example, the second authentication pattern included in the authentication data may be composed of at least one of the type of button, the number of times the button is pressed, the time the button is pressed, and the time interval between button presses. Here, the aerosol generating device 1000 may determine whether a push input pattern sensed by a button signal corresponds to the second authentication pattern. Meanwhile, the aerosol generating device 1000 may determine whether a predetermined input is received based on a user input that initiates user authentication.

[0286] According to an embodiment of the present disclosure, when a touch input for a predetermined time (e.g., 3 seconds) or more is detected via a contact sensor, the aerosol generating device 1000 may determine that a predetermined input has been received based on a user input for starting user authentication. Here, when the aerosol generating device 1000 receives a predetermined touch input based on a user input for starting user authentication, it may determine whether a contact sensor signal received after receiving the predetermined touch input corresponds to authentication data. In the present disclosure, a case where a touch input is received for a predetermined time (e.g., 3 seconds) or more as a user input for starting user authentication will be described as an example, but is not limited thereto.

[0287] 29, the contact sensor 1510 may be disposed in an area of ​​the side wall 111 of the lower body 110. For example, the contact sensor 1510 may be disposed in an area of ​​the side wall 111 where a particular part of the user's body (e.g., thumb) is located when the body 100 is gripped by the user.

[0288] The aerosol generating device 1000 may determine whether the touch input is a valid input that satisfies a predetermined criterion based on the signal of the contact sensor 1510. For example, the aerosol generating device 1000 may determine whether the touch input is a valid input that satisfies a predetermined criterion by taking into consideration the level of the signal of the contact sensor 1510, the degree to which the level of the signal of the contact sensor 1510 has changed, and the like.

[0289] Meanwhile, the aerosol generating device 1000 may determine the type of touch input based on the time during which the signal level of the contact sensor 1510 is maintained. For example, the aerosol generating device 1000 may determine that a short touch input has been received if the time during which the signal level of the contact sensor 1510 is maintained is less than a predetermined minimum time (e.g., 1 second). For example, the aerosol generating device 1000 may determine that a long touch input has been received if the time during which the signal level of the contact sensor 1510 is maintained is equal to or greater than a predetermined minimum time (e.g., 1 second).

[0290] Meanwhile, the aerosol generating device 1000 may determine the type of touch input based on a change in a position where an object touches the contact sensor 1510. For example, when a touch input is detected in one area of ​​the contact sensor 1510 and the position where the touch input is detected changes continuously in a specific direction, the aerosol generating device 1000 may determine that a sweeping touch input has been received in a specific direction.

[0291] 30 and 31, the first authentication pattern may be formed by a combination of the number of times an object touches the object, the time during which the object touches the object, and the time interval between the times when the object touches the object.

[0292] In one embodiment, after starting user authentication, the user may input three consecutive short touch inputs starting from time t1, one short touch input starting from time t4 when a predetermined time has elapsed since time t3, and two short touch inputs starting from time t5 when a predetermined time has elapsed since time t4.

[0293] The aerosol generating device 1000 may confirm that after receiving a touch input at time t1, it receives another touch input at time t2 within a predetermined time, and receives another touch input at time t3 within a predetermined time from time t2. Here, since it does not receive a valid touch input within a predetermined time after receiving the touch input at time t3, the aerosol generating device 1000 may determine that three short touch inputs have been input in the first section 3010.

[0294] Meanwhile, since the aerosol generating device 1000 does not receive a valid touch input for a predetermined time after receiving the touch input at time t4, it can determine that one short touch input was input in the second section 3020.

[0295] Meanwhile, the aerosol generating device 1000 may confirm that it receives a touch input again at time t6 within a predetermined time after receiving a touch input at time t5. Here, since it does not receive a valid touch input within a predetermined time after receiving the touch input at time t6, the aerosol generating device 1000 may determine that two short touch inputs have been input in the third section 3030.

[0296] The aerosol generating device 1000 may determine whether a signal having a pattern in which short touch inputs are input three times, one time, and two times in a plurality of sections 3010, 3020, and 3030 separated from each other at time intervals corresponds to authentication data. Here, if any one of the number of sections in which touch inputs are input and the number of short touch inputs input in each section is different from the first authentication pattern, the aerosol generating device 1000 may determine that the signal of the contact sensor is not a signal corresponding to authentication data.

[0297] In another embodiment, after starting user authentication, the user may input one short touch input and one long touch input starting from time t1, the user may input one long touch input starting from time t4 when a predetermined time has elapsed since time t3, and the user may input two consecutive short touch inputs starting from time t6 when a predetermined time has elapsed since time t5.

[0298] The aerosol generating device 1000 may receive a short touch input at time t1, and then receive a touch input at time t2 within a predetermined time, and confirm that the touch input is maintained until time t3. Here, if the time from time t2 to time t3 is equal to or greater than a predetermined minimum time (e.g., 1 second), the aerosol generating device 1000 may determine that the touch input received from time t2 to time t3 is a long touch input. In addition, since the aerosol generating device 1000 does not receive a valid touch input within a predetermined time after the touch input reception at time t3 ends, the aerosol generating device 1000 may determine that one short touch input and one long touch input have been input in the first section 3110.

[0299] Meanwhile, the aerosol generating device 1000 may confirm that it receives a long touch input from time t4 to time t5. In addition, since it does not receive a valid touch input for a predetermined time after the touch input reception ends at time t5, the aerosol generating device 1000 may determine that a long touch input has been input once in the second section 3120.

[0300] Meanwhile, the aerosol generating device 1000 may confirm that it receives a touch input again at time t7 within a predetermined time after receiving a touch input at time t6. Here, since it does not receive a valid touch input within a predetermined time after receiving the touch input at time t7, the aerosol generating device 1000 may determine that two short touch inputs have been input in the third section 3130.

[0301] The aerosol generating device 1000 may determine whether a signal of a pattern consisting of short and long touch inputs inputted in a plurality of sections 3110, 3120, and 3130 separated from each other at time intervals corresponds to authentication data. Here, the aerosol generating device 1000 may determine that the signal of the contact sensor is not a signal corresponding to authentication data if any one of the number of sections in which the touch input is inputted and the combination of the short and long touch inputs inputted in each section is different from the first authentication pattern.

[0302] 32A and 32B, the first authentication pattern may be formed by a combination of changes in the number of times an object touches the object and the position where the object touches the object.

[0303] In one embodiment, the user may move the upper finger 3200 while the finger 3200 is in contact with the lower region of the contact sensor 1510. Here, the aerosol generating device 1000 may determine that an upward sweeping touch input is received based on a signal from the contact sensor 1510.

[0304] Also, the user may move the finger 3200 to the right while the finger 3200 is in contact with the left region of the contact sensor 1510. Here, the aerosol generating device 1000 may confirm that it receives a sweeping touch input to the right based on a signal from the contact sensor 1510.

[0305] The aerosol generating device 1000 can determine whether a signal of a pattern consisting of the number of consecutively received sweeping touch inputs (e.g., 2 times) and the order of the directions of the sweeping touch inputs (e.g., up, left) corresponds to authentication data. Here, if any one of the number of consecutively received sweeping touch inputs and the order of the directions of the sweeping touch inputs differs from the first authentication pattern, the aerosol generating device 1000 can determine that the signal of the contact sensor is not a signal corresponding to authentication data.

[0306] Meanwhile, when the aerosol generating device 1000 receives a user input for terminating user authentication, it can also determine whether the contact sensor signal corresponds to authentication data. For example, when the aerosol generating device 1000 detects a touch input for a predetermined time (e.g., 3 seconds) or more through the contact sensor, it can determine that the predetermined input has been received as a user input for terminating user authentication. Here, the aerosol generating device 1000 can determine whether the contact sensor signal received during the time between the time when the user input for starting user authentication is received and the time when the user input for terminating user authentication is received is a signal corresponding to authentication data. In the present disclosure, a case where a touch input is received for a predetermined time (e.g., 3 seconds) or more as a user input for terminating user authentication will be described as an example, but is not limited thereto.

[0307] According to an embodiment of the present disclosure, when the aerosol generating device 1000 detects a push input via a button for a predetermined time (e.g., 3 seconds) or more, it can determine that a predetermined input has been received as a user input for starting user authentication. Here, when the aerosol generating device 1000 receives a predetermined push input as a user input for starting user authentication, it can determine whether a button signal received after receiving the predetermined push input corresponds to authentication data. In the present disclosure, a case where a push input is received for a predetermined time (e.g., 3 seconds) or more as a user input for starting user authentication will be described as an example, but is not limited thereto.

[0308] 33, the button 1210 may be disposed in an area of ​​the side wall 111 of the lower body 110. For example, the button 1210 may be disposed in an area of ​​the side wall 111 where a particular part of the user's body (e.g., thumb) is located when the body 100 is gripped by the user.

[0309] In one embodiment, a plurality of mutually separated buttons 1211, 1212, 1213 may be arranged in one region of the side wall 111 of the lower body 110. For example, a first button 1211 associated with turning on / off the power of the aerosol generating device 1000, second and third buttons 1212, 1213 associated with increasing / decreasing the amount of aerosol generated, etc. may be arranged in one region of the side wall 111 of the lower body 110.

[0310] Meanwhile, the aerosol generating device 1000 can determine the type of push input based on the time during which the signal level of the button 1210 is maintained. Here, the signal of the button 1210 can be maintained at a predetermined level while the button 1210 is maintained in a pressed state. For example, the aerosol generating device 1000 can determine that a short push input has been received if the time during which the signal level of the button 1210 is maintained is less than a predetermined minimum time (e.g., 1 second), and can determine that a long push input has been received if the time during which the signal level of the button 1210 is maintained is equal to or greater than a predetermined minimum time (e.g., 1 second).

[0311] Referring to Figures 34 to 36, the second authentication pattern may be composed of at least one of the type of button, the number of times the button is pressed, the time the button remains pressed, and the time interval between when the button is pressed.

[0312] 34, in one embodiment, after starting user authentication, a user may input one short push at time t1, and may input three short pushes at time t2 when a predetermined time has elapsed since time t1, and may input two consecutive short pushes at time t5 when a predetermined time has elapsed since time t4.

[0313] Since the aerosol generating device 1000 does not receive a valid push input for a predetermined time after receiving a push input at time t1, it can determine that one short push input was input in the first section 3410.

[0314] Meanwhile, the aerosol generating device 1000 may confirm that after receiving a push input at time t2, it receives another push input at time t3 within a predetermined time, and receives another push input at time t4 within a predetermined time from time t3. Here, since it does not receive a valid push input within a predetermined time after receiving the push input at time t4, the aerosol generating device 1000 may determine that three short push inputs have been input in the second section 3420.

[0315] Meanwhile, the aerosol generating device 1000 may confirm that it receives another push input at time t6 within a predetermined time after receiving a push input at time t5. Here, since it does not receive a valid push input within a predetermined time after receiving the push input at time t6, the aerosol generating device 1000 may determine that two short push inputs have been input in the third section 3430.

[0316] The aerosol generating device 1000 may determine whether a signal having a pattern in which short push inputs are input once, three times, and twice in a plurality of sections 3410, 3420, and 3430 separated from each other at time intervals corresponds to authentication data. Here, the aerosol generating device 1000 may determine that the button signal is not a signal corresponding to authentication data if any one of the number of sections in which push inputs are input and the number of short push inputs input in each section is different from the second authentication pattern.

[0317] 35, in one embodiment, after starting user authentication, a user may input one short push input and one long push input starting at time t1. The user may also input one long push input at time t4, which is a time period exceeding a predetermined time from time t3. The user may also input two consecutive short push inputs starting at time t6, which is a time period exceeding a predetermined time from time t5.

[0318] The aerosol generating device 1000 may receive a short push input at time t1, and then receive a push input at time t2 within a predetermined time, and confirm that the push input is maintained until time t3. Here, if the time from time t2 to time t3 is equal to or greater than a predetermined minimum time (e.g., 1 second), the aerosol generating device 1000 may determine that the push input received from time t2 to time t3 is a long push input. In addition, since the aerosol generating device 1000 does not receive a valid push input within a predetermined time after the reception of the push input at time t3 ends, the aerosol generating device 1000 may determine that one short push input and one long push input have been input in the first section 3510.

[0319] Meanwhile, the aerosol generating device 1000 may confirm that it receives a long push input from time t4 to time t5. In addition, since it does not receive a valid push input for a predetermined time after the reception of the push input at time t5 ends, the aerosol generating device 1000 may determine that one long push input has been input in the second section 3520.

[0320] Meanwhile, the aerosol generating device 1000 may confirm that it receives another push input at time t7 within a predetermined time after receiving a push input at time t6. Here, since it does not receive a valid push input within a predetermined time after receiving the push input at time t7, the aerosol generating device 1000 may determine that two short push inputs have been input in the third section 3530.

[0321] The aerosol generating device 1000 may determine whether a signal pattern consisting of short push inputs and long push inputs inputted in a plurality of sections 3510, 3520, and 3530 separated from each other at time intervals corresponds to authentication data. Here, the aerosol generating device 1000 may determine that the button signal is not a signal corresponding to authentication data if any one of the number of sections in which push inputs are inputted and the combination of short push inputs and long push inputs inputted in each section is different from the second authentication pattern.

[0322] 36, in one embodiment, after starting user authentication, the user can input one short push input by pressing the first button 1211 at time t1. The user can input two short push inputs by pressing the second button 1212 and the third button 1213 in sequence from time t2, which is a time that exceeds a predetermined time from time t1. The user can input three short push inputs by pressing the second button 1212 and the first button 1211 in sequence from time t4, which is a time that exceeds a predetermined time from time t3. The user can input one short push input by pressing the third button 1213 at time t7, which is a time that exceeds a predetermined time from time t6.

[0323] Since the aerosol generating device 1000 does not receive a valid push input for a predetermined time after receiving a push input via the first button 1211 at time t1, it can determine that a short push input was input once via the first button 1211 in the first section 3610.

[0324] Meanwhile, the aerosol generating device 1000 may confirm that after receiving a push input via the second button 1212 at time t2, it again receives a push input via the third button 1213 within a predetermined time at time t3. Here, since no valid push input is received within a predetermined time after receiving the push input at time t3, the aerosol generating device 1000 may determine that one short push input is input via the second button 1212 and one short push input is input via the third button 1213 in the second section 3620.

[0325] Meanwhile, the aerosol generating device 1000 may confirm that after receiving a push input through the second button 1212 at time t4, it receives another push input through the first button 1211 at time t5 within a predetermined time from time t5, and receives another push input through the first button 1211 at time t6 within a predetermined time from time t5. Here, since it does not receive a valid push input within a predetermined time after receiving the push input at time t6, the aerosol generating device 1000 may determine that one short push input has been input through the second button 1212 and two short push inputs have been input through the first button 1211 in the third section 3630.

[0326] On the other hand, since the aerosol generating device 1000 does not receive a valid push input for a predetermined time after receiving a push input via the third button 1213 at time t7, it can determine that a short push input was input once via the third button 1213 in the fourth section 3640.

[0327] The aerosol generating device 1000 may determine whether a signal pattern consisting of short push inputs and long push inputs inputted in a plurality of sections 3610, 3620, 3630, and 3640 separated from one another at time intervals corresponds to authentication data. Here, if any one of the number of sections in which push inputs are inputted, the combination of short push inputs and long push inputs inputted in each section, and the type of button corresponding to the push input inputted in each section is different from the second authentication pattern, the aerosol generating device 1000 may determine that the button signal is not a signal corresponding to authentication data.

[0328] Meanwhile, when the aerosol generating device 1000 receives a user input to end user authentication, it can also determine whether the button signal corresponds to authentication data. For example, when the aerosol generating device 1000 detects a push input via a button for a predetermined time (e.g., 3 seconds) or more, it can determine that the predetermined input has been received as a user input to end user authentication. Here, the aerosol generating device 1000 can determine whether the button signal received during the time between the time when the user input to start user authentication is received and the time when the user input to end user authentication is received is a signal corresponding to authentication data. In the present disclosure, a case where a push input is received for a predetermined time (e.g., 3 seconds) or more as a user input to end user authentication will be described as an example, but is not limited to this.

[0329] Referring to FIG. 28, in operation S2804, the aerosol generating device 1000 can supply power to the heater 262 if the signal from the input device corresponds to the authentication data.

[0330] On the other hand, in operation S2805, the aerosol generating device 1000 can cut off the supply of power to the heater 262 if authentication data is not stored in the memory 1400 or if the signal from the input device is not a signal corresponding to the authentication data.

[0331] 37A and 37B are flowcharts showing an operation method of an aerosol generating device according to another embodiment of the present disclosure. Detailed description of the contents that overlap with the contents described in FIGS. 28 to 32 will be omitted.

[0332] Referring to FIG. 37A, in operation S3701, the aerosol generating device 1000 can check whether authentication data for user authentication is stored in the memory 1400.

[0333] In operation S3702, the aerosol generating device 1000 may determine whether to start user authentication if authentication data is stored in the memory 1400. For example, the aerosol generating device 1000 may start user authentication if it receives a touch input via a contact sensor for a predetermined time (e.g., 3 seconds) or more. For example, the aerosol generating device 1000 may start user authentication if it receives a push input via a button for a predetermined time (e.g., 3 seconds) or more.

[0334] Meanwhile, when user authentication starts, the aerosol generating device 1000 may output a message notifying the start of user authentication through an output device of the input / output interface 1200. For example, when user authentication starts, the aerosol generating device 1000 may irradiate light through the light source 153. Here, the light irradiated from the light source 153 may be directed toward the chamber C1 through the outside of the insertion space 214. For example, when user authentication starts, the aerosol generating device 1000 may generate vibrations by a motor that provides a haptic effect.

[0335] When user authentication starts in operation S3703, the aerosol generating device 1000 may monitor a signal from an input device. For example, the aerosol generating device 1000 may determine whether a predetermined object has been touched based on a signal from a force sensor and / or a touch sensor. For example, the aerosol generating device 1000 may determine whether a button press input has been received based on a signal from a button.

[0336] The aerosol generating device 1000 may determine whether the signal of the input device corresponds to authentication data in operation S3704. For example, the aerosol generating device 1000 may determine whether a touch input pattern, which is detected by a signal of a contact sensor and is composed of at least one of the number of times an object contacts, the time when the object contacts, the time interval between the times when the object contacts, and the change in the position where the object contacts, corresponds to a first authentication pattern. For example, the aerosol generating device 1000 may determine whether a push input pattern, which is detected by a signal of a button and is composed of at least one of the type of button, the number of times the button is pressed, the time the button is pressed, and the time interval between the times when the button is pressed, corresponds to a second authentication pattern.

[0337] In operation S3705, when the signal from the input device corresponds to the authentication data, the aerosol generating device 1000 can supply power to the heater 262. Here, when the signal from the input device corresponds to the authentication data, the aerosol generating device 1000 can irradiate light of a predetermined hue (e.g., white) via the light source 153.

[0338] Meanwhile, in operation S3706, when the signal from the input device does not correspond to the authentication data, the aerosol generating device 1000 can cut off the supply of power to the heater 262. Here, when the signal from the input device does not correspond to the authentication data, the aerosol generating device 1000 can irradiate light of a predetermined hue (e.g., red) via the light source 153.

[0339] The aerosol generating device 1000 may update the number of times that the user authentication has failed in the operations S3707 and S3708. The aerosol generating device 1000 may determine whether the updated number of times is equal to or greater than a predetermined number of times.

[0340] If the number of times that user authentication has failed is less than a predetermined number, the aerosol generating device 1000 can determine whether the signal from the input device is a signal corresponding to authentication data each time user authentication starts.

[0341] Meanwhile, the aerosol generating device 1000 may block user authentication when the number of times user authentication has failed is equal to or exceeds a predetermined number in operation S3709. For example, the aerosol generating device 1000 may interrupt the determination of whether the signal of the input device corresponds to authentication data by blocking the start of user authentication when the number of times user authentication has failed is equal to or exceeds a predetermined number.

[0342] When user authentication is interrupted, the aerosol generating device 1000 may restrict the user's access to the authentication data stored in the memory 1400. For example, the aerosol generating device 1000 may restrict modification or deletion of the authentication data stored in the memory 1400.

[0343] Meanwhile, when the aerosol generating device 1000 receives a user input to start user authentication in a state where the user authentication is blocked, the aerosol generating device 1000 may output a message notifying that the user authentication is blocked through an output device of the input / output interface 1200. For example, when the aerosol generating device 1000 receives a user input to start user authentication in a state where the user authentication is blocked, the aerosol generating device 1000 may irradiate light of a predetermined color (e.g., red) through the light source 153.

[0344] 38, the aerosol generating device 1000 may process the authentication data stored in the memory 1400 based on a control signal received from the external device 3400. Here, the external device 3800 may be a device having authority to process the authentication data. For example, when the aerosol generating device 1000 receives a predetermined control signal for deleting the authentication data from the external device 3800 via the communication interface 1100, the aerosol generating device 1000 may delete the authentication data stored in the memory 1400. In this figure, a case where the external device 3800 transmits a control signal to the aerosol generating device 1000 using wired communication using the cable 3410 is described as an example, but the present disclosure is not limited thereto.

[0345] The aerosol generating device 1000 may release the block of user authentication when the authentication data stored in the memory 1400 is changed or deleted. The aerosol generating device 1000 may initialize the number of times user authentication has failed when the authentication data stored in the memory 1400 is changed or deleted.

[0346] 37B, the aerosol generating device 1000 may cut off the power supply to the heater 262 if the authentication data is not stored in the memory 1400 in operation S3710. Here, the aerosol generating device 1000 may output a message requesting generation of authentication data through an output device of the input / output interface 1200.

[0347] The aerosol generating device 1000 can monitor whether a function for generating authentication data is activated in operation S3711. For example, the aerosol generating device 1000 can activate the function for generating authentication data when a signal pattern received from an input device is a predetermined pattern for activating the function for generating authentication data in a state where no authentication data is stored in the memory 1400. For example, the aerosol generating device 1000 can activate the function for generating authentication data when a control signal for activating the function for generating authentication data is received from an external device via the communication interface 1100 in a state where no authentication data is stored in the memory 1400.

[0348] Here, the aerosol generating device 1000 may activate the function of generating authentication data for a predetermined time limit. For example, the aerosol generating device 1000 may activate the function of generating authentication data for a predetermined time limit of one minute from the time when the aerosol generating device 1000 receives a control signal for activating the function of generating authentication data from an external device via the communication interface 1100.

[0349] When the function of generating authentication data is activated in the operations S3712 and S3713, the aerosol generating device 1000 may monitor a signal of the input device. The aerosol generating device 1000 may determine whether the signal of the input device satisfies a predetermined criterion. For example, the aerosol generating device 1000 may determine that the signal of the contact sensor satisfies the predetermined criterion when the signal of the force sensor and / or the touch sensor changes to a predetermined minimum level or more. For example, the aerosol generating device 1000 may determine that the signal of the contact sensor satisfies the predetermined criterion when at least one of a short touch input, a long touch input, and a sweeping touch input is received a predetermined number of times (e.g., twice). For example, the aerosol generating device 1000 may determine that the signal of the button satisfies the predetermined criterion when at least one of a short push input and a long push input is received a predetermined number of times (e.g., twice).

[0350] If the signal of the input device satisfies a predetermined criterion, the aerosol generating device 1000 may generate authentication data corresponding to the pattern of the signal of the input device in operation S3714. The aerosol generating device 1000 may store the generated authentication data in the memory 1400.

[0351] Meanwhile, in operation S3715, the aerosol generating device 1000 can deactivate the function of generating authentication data if the signal from the input device does not meet a predetermined criterion.
