The extension portion 232 of the lower case 230 may cover an upper portion of the sensor receiving portion 137.

[0125] A gap through which air can flow may be formed between the sensor receiving part 137 and the lower case 230. Air may pass between the sensor receiving part 137 and the lower case 230 and flow into the cartridge inlet 224. The second sensor 180 may sense the flow of air passing between the sensor receiving part 137 and the lower case 230 and flowing into the cartridge inlet 224.

[0126] 15 and 16, the cartridge 200 may include a stick stopper 217 protruding inward from the periphery of the insertion space 214 at a position adjacent to the other end or the lower end of the insertion space 214. The stick stopper 217 may protrude in a radially inward direction. The stick stopper 217 may be formed on the outer wall 211 and / or the inner wall 212 of the first container 210.

[0127] The stick stopper 217 may include a plurality of stick stoppers. The stick stopper 217 may include three stick stoppers. A plurality of stick stoppers 217 may be arranged along the periphery of the insertion space 214. The stick stoppers 217 may be arranged in the circumferential direction. The stick stoppers 217 may be arranged spaced apart from each other. The stick stopper 217 may have a rib shape or a ring shape extending in the circumferential direction along the periphery of the insertion space 214. 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.

[0128] 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.

[0129] In addition, the reduction in the amount of air flowing from the second chamber C2 into the insertion space 214 can be minimized.

[0130] 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.

[0131] 17 and 18, 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 19 to 22, 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.

[0139] 19 and 20, 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 and pivot the cover 310 in a first direction.

[0140] 20 and 21, 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.

[0141] 21 and 22, 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] In addition, the stick 400 can be restricted from moving inside the second chamber C2.

Here, when an 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, and the lost energy may be released as thermal energy to heat the aerosol generating material adjacent to the magnetic material. Here, the object that generates heat due to the magnetic field may be called a susceptor.

[0268] On the other hand, the aerosol generating module 1300 can also generate an aerosol from an aerosol generating substance by generating ultrasonic vibrations.

[0269] The aerosol generating module 1300 may be referred to as a cartomizer, an atomizer, a vaporizer, or the like.

[0270] 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.

[0271] For example, the memory 1400 can store application programs designed to perform various tasks that can be processed by the control unit 1700, and can selectively provide portions of the stored application programs upon request of the control unit 1700.

[0272] 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, a puff may refer to an inhalation by a user, and inhalation may be an act of a user drawing air into the oral cavity, nasal cavity, or lungs of the user through the mouth or nose.

[0274] The sensor module 1500 can include at least one sensor.

[0275] 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.

[0276] For example, the sensor module 1500 may include a sensor (hereinafter, referred to as a temperature sensor) that detects the temperature of a heater included in the aerosol generation module 1300, the temperature of an aerosol generating material, etc.

[0277] Here, the heater included in the aerosol generation module 1300 may function as a temperature sensor. For example, the electrically resistive material of the heater is a material having a temperature coefficient of resistance, and the sensor module 1500 may sense the temperature of the heater by measuring the resistance of the heater, which changes depending on the temperature.

[0278] 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).

[0279] 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.

[0280] 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.

For example, the battery 1600 may be, but is not limited to, a lithium-ion battery, a lithium-polymer battery, a lithium-ion phosphate battery, etc. For example, the battery 1600 may be a lithium cobalt oxide (LiCoO 2 ) battery, lithium titanate battery, etc.

[0285] 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.

[0286] 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, and 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.

[0287] 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 wirelessly receive power via an antenna included in a communication module for wireless communication, and can charge the battery 1600 using the wirelessly supplied power.

[0288] 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.

[0289] The control unit 1700 is connected to each component provided in the aerosol generating device 1000, and can transmit and / or receive signals between each component to control the overall operation of each component.

[0290] The control unit 1700 may include at least one processor, and may use the processor included therein 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.

[0291] 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 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.

[0292] 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.

[0293] 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.

[0294] The control unit 1700 can control the operation of each component included in the aerosol generating device 1000 depending on the occurrence of puffs and / or the number of puffs. For example, the control unit 1700 can control the heater to change or maintain the temperature based on the temperature profile stored in the memory 1400.

[0295] The control unit 1700 may control to cut off the power supply to the heater according to a predetermined condition, 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 number of puffs reaches a preset maximum number of puffs, when no puffs are detected for a preset time or more, when the remaining capacity of the battery 1600 is less than a predetermined value, etc.

[0296] 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.

[0297] The control unit 1700 may control the supply of power to the heater using at least one of a pulse width modulation (PWM) method and a proportional-integral-differential (PID) method.

[0298] For example, the control unit 1700 may control the heater to be supplied with a current pulse having a predetermined frequency and duty ratio using a PWM method, where the control unit 1700 may control the power supplied to the heater by adjusting the frequency and duty ratio of the current pulse.

[0299] 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 using a PID method, which is a feedback control method based on a difference between the heater temperature and the target temperature, a value obtained by integrating the difference over time, and a value obtained by differentiating the difference over time.

[0300] Meanwhile, the PWM method and the PID method have been described as examples of the control method for supplying power to the heater, 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.

[0301] FIG. 35 is a flowchart showing an operation method of the aerosol generation device according to an embodiment of the present disclosure. Hereinafter, the directions of the aerosol generation device 1000 can be defined based on the Cartesian coordinate system shown in FIGS. 36 to 38. 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.

[0303] The aerosol generating device 1000 can determine the direction in which the aerosol generating device 1000 faces in operation S3520. For example, the aerosol generating device 1000 can determine the direction in which the aerosol generating device 1000 faces in a Cartesian coordinate system based on a signal output from an acceleration sensor. Here, the direction in which the aerosol generating device 1000 faces can be the direction in which the upper end of the aerosol generating device 1000, for example, the upper wall 303 of the cap 300, faces.

[0304] The aerosol generating device 1000 may determine whether a predetermined input is received from a user in operation S3530. Here, the user may input the predetermined input by using a movement of the aerosol generating device 1000. For example, the aerosol generating device 1000 may determine whether a predetermined number of tap inputs of hitting the aerosol generating device 1000 are received based on signals from an acceleration sensor and / or a gyro sensor.

[0305] When the aerosol generating device 1000 receives a predetermined input from a user in operation S3540, the aerosol generating device 1000 may determine whether the direction in which the aerosol generating device 1000 faces is a preset direction. For example, the preset direction may be a direction in which the upper end of the aerosol generating device 1000 faces upward and the lower end of the aerosol generating device 1000 faces downward.

[0306] In the operation S3550, the aerosol generating device 1000 can irradiate light via the light source 153 when the direction in which the aerosol generating device 1000 is facing is a preset direction.

[0307] Referring to Figures 36 and 37, when the upper and lower ends of the aerosol generating device 1000 are facing upward and downward, respectively, a user can input a predetermined input to the aerosol generating device 1000 by tapping the lower body 110 a preset number of times (e.g., three times) as a tap input 3710.

[0308] The aerosol generating device 1000 receives a predetermined input while facing a preset direction, and can irradiate light through the light source 153. Here, the light irradiated from the light source 153 can be directed toward the chamber C1 along the outer periphery of the insertion space 214. In addition, the light irradiated toward the chamber C1 can be dispersed to the outside of the cap 300 through the chamber C1, the outer wall 211, and the cap body 310 in this order.

[0309] In addition, the light is emitted to the outside through the outer wall 211 and the cap body 310, so that the interior 3810 of the first container 210 can be displayed to the outside. This allows the user to intuitively check the internal state of the first container 210. In addition, the user can accurately check the volume 3815 of the liquid stored in the chamber C1 even in a dark environment.

[0310] Meanwhile, the aerosol generating device 1000 can change the hue of the light irradiated through the light source 153. The aerosol generating device 1000 can determine the hue of the light irradiated through the light source 153 according to the number of puffs by the user. For example, the aerosol generating device 1000 can determine the hue of the light to be white when the current number of puffs stored in the memory 1400 is less than a first number, blue when the current number of puffs is equal to or greater than the first number and less than a second number, yellow when the current number of puffs is equal to or greater than the second number and less than the maximum number of puffs, and red when the current number of puffs is equal to or greater than the maximum number of puffs.

[0311] On the other hand, in operation S3560, if the direction in which the aerosol generating device 1000 is facing is not a preset direction, the aerosol generating device 1000 can execute an operation corresponding to a predetermined input regardless of the light source 153.

[0312] Referring to Figure 38, when the upper and lower ends of the aerosol generating device 1000 are facing in the forward / backward or left / right directions, respectively, a user can input a predetermined input to the aerosol generating device 1000 by tapping the lower body 110 a preset number of times (e.g., three times) as a tap input 3810.

[0313] Since the aerosol generating device 1000 receives a predetermined input while facing a direction different from the preset direction, it can perform an operation corresponding to the predetermined input, which is to input a tap input a preset number of times (e.g., three times) unrelated to the light source 153.

[0314] For example, an operation corresponding to a predetermined input unrelated to the light source 153 may be an operation of updating data stored in the memory 1400. When the aerosol generating device 1000 receives a predetermined input while facing a direction different from a preset direction, the aerosol generating device 1000 may update a temperature profile corresponding to the predetermined input among a plurality of temperature profiles stored in the memory 1400 with the used temperature profile.

[0315] For example, an action corresponding to a predetermined input unrelated to the light source 153 may be an action to activate the lock mode. When the aerosol generating device 1000 receives a predetermined input in a state where the aerosol generating device 1000 is oriented in a direction different from a preset direction, the aerosol generating device 1000 may cut off the supply of power to the heater 262.

[0316] For example, an action corresponding to a predetermined input unrelated to the light source 153 may be an action to activate a function to release the lock mode. When the aerosol generating device 1000 receives a predetermined input while facing a direction different from a preset direction, the aerosol generating device 1000 may activate the function to release the lock mode and monitor a signal from the operation sensor. Here, the aerosol generating device 1000 may check a pattern of the direction in which the aerosol generating device 1000 faces and / or the number of times that the aerosol generating device 1000 has received a tap input based on the signal from the operation sensor. In addition, when the checked pattern corresponds to a preset pattern, the aerosol generating device 1000 may release the lock mode and supply power to the heater 262.

[0317] As described above, according to at least one of the embodiments of the present disclosure, the efficiency of gas flow can be improved, thereby improving the efficiency of heat transfer of the aerosol to the stick 400.
