[0026] In one embodiment, the aerosol generating device 100 may consist only of a main body. In this case, the components included in the aerosol generating device 100 may be located within the main body. In another embodiment, the aerosol generating device 100 may consist of a main body and a cartridge containing an aerosol generating substance. In this case, the components included in the aerosol generating device 100 may be located in at least one of the main body or the cartridge.

[0027] The communication interface 110 may include at least one communication module for communicating with external devices and / or networks. For example, the communication interface 110 may include a communication module for wired communication (e.g., Universal Serial Bus (USB)). For example, the communication interface 110 may include a communication module for wireless communication (e.g., Wi-Fi, Bluetooth, Bluetooth Low Energy (BLE), ZigBee, or Near Field Communication (NFC)).

[0028] The input / output interface 120 may include an input device (not shown) for receiving commands from a user and / or an output device (not shown) for outputting information to a user. For example, the input device may include a touch panel, physical buttons, a microphone, etc. For example, the output device may include a display device (e.g., a monitor or light-emitting diode (LED)) for outputting visual information, an audio device (e.g., a speaker or buzzer) for outputting auditory information, a motor for outputting tactile information such as tactile effects, etc.

[0029] The input / output interface 120 can send data corresponding to commands input by the user via the input device to another component (or other component) of the aerosol generating apparatus 100. The input / output interface 120 can also output information corresponding to data received from another component (or other component) of the aerosol generating apparatus 100 via the output device.

[0030] The aerosol generation module 130 can generate aerosols from aerosol generating substances. Here, the aerosol generating substances can be liquid, solid, or gel-like substances capable of generating aerosols, or a combination of two or more aerosol generating substances.

[0031] According to one embodiment, the liquid aerosol generating substance may be a liquid comprising tobacco-containing materials having volatile tobacco flavor components. According to another embodiment, the liquid aerosol generating substance may be a liquid comprising non-tobacco materials. For example, the liquid aerosol generating substance may include water, solvents, nicotine, plant extracts, seasonings, flavoring agents, vitamin mixtures, etc.

[0032] Solid aerosol generating materials can include solid materials based on tobacco raw materials such as reconstituted tobacco sheets, shredded tobacco, or granular tobacco. Additionally, solid aerosol generating materials can include solid materials containing flavor modifiers and flavoring ingredients. For example, flavor modifiers can include calcium carbonate, sodium bicarbonate, calcium oxide, etc. Flavoring ingredients can include natural materials such as herbal granules, or materials containing aromatic components (e.g., silica, zeolite, or dextrin).

[0033] In addition, aerosol-generating substances may also include aerosol forming agents such as glycerol or propylene glycol.

[0034] The aerosol generation module 130 may include at least one heater (not shown).

[0035] The aerosol generation module 130 may include a resistance heater. For example, the resistance heater may include at least one conductive track. The resistance heater can be heated as current flows through the conductive track. In this case, the aerosol generating material can be heated by the heated resistance heater.

[0036] Conductive tracks can include resistive materials. In one example, a conductive track can be formed from a metallic material. In another example, a conductive track can be formed from a ceramic material, carbon, a metal alloy, or a composite of a ceramic material and a metal.

[0037] Resistance heaters may include conductive tracks formed in any of a variety of shapes. For example, conductive tracks may be formed in any of the following forms: tubular, plate-shaped, needle-shaped, rod-shaped, and coil-shaped.

[0038] The aerosol generation module 130 may include a heater using an induction heating method. For example, the induction heater may include a conductive coil. The induction heater can generate an alternating magnetic field that periodically changes direction by adjusting the current flowing through the conductive coil. When the alternating magnetic field is applied to a magnet, energy loss may occur in the magnet due to eddy current losses and hysteresis losses, and the lost energy can be released as heat. Therefore, the aerosol generating material disposed adjacent to the magnet can be heated. Here, the object that generates heat due to the magnetic field may be referred to as a sensor.

[0039] In addition, the aerosol generation module 130 can generate ultrasonic vibrations, thereby generating aerosols from aerosol generating substances.

[0040] The aerosol generating device 100 may be referred to as a cartomizer, atomizer, or vaporizer.

[0041] The memory 140 can store programs for processing and controlling each signal in the controller 170, and can also store processed data and data to be processed.

[0042] For example, memory 140 may store applications designed to perform various tasks that can be processed by controller 170. Memory 140 may selectively provide some of the stored applications in response to requests from controller 170.

[0043] For example, memory 140 may store data regarding the operating time of aerosol generating device 100, maximum number of inhalations, current number of inhalations, number of uses of battery 160, at least one temperature profile, user inhalation patterns, and charging / discharging data. Here, "inhalation" refers to inhalation performed by a user. "Inhalation" refers to the act of a user bringing air or other substances into the user's oral cavity, nasal cavity, or lungs through the user's mouth or nose.

[0044] The memory 140 may include at least one of volatile memory (e.g., dynamic random access memory (DRAM), static random access memory (SRAM) or synchronous dynamic random access memory (SDRAM)), non-volatile memory (e.g., flash memory), hard disk drive (HDD) or solid-state drive (SSD).

[0045] The sensor module 150 may include at least one sensor.

[0046] For example, sensor module 150 may include a sensor for sensing suction (hereinafter referred to as a "suction sensor"). In this case, the suction sensor may be implemented as a proximity sensor, pressure sensor, gyroscope sensor, accelerometer sensor, magnetic field sensor, etc.

[0047] For example, sensor module 150 may include a sensor (hereinafter referred to as a "temperature sensor") for sensing the temperature of the heater included in aerosol generation module 130 and the temperature of the aerosol-generating substance. In this case, the heater included in aerosol generation module 130 may also be used as a temperature sensor. For example, the resistive material of the heater may be a material having a predetermined temperature coefficient of resistance. Sensor module 150 may measure the temperature-dependent resistance of the heater, thereby sensing the temperature of the heater.

[0048] For example, if the body of the aerosol generating device 100 is configured to allow a rod to be inserted therein, the sensor module 150 may include a sensor for sensing the insertion of the rod (hereinafter referred to as the "rod detection sensor").

[0049] For example, if the aerosol generating device 100 includes a cartridge, the sensor module 150 may include a sensor (hereinafter referred to as a "cartridge detection sensor") for sensing the installation / removal of the cartridge and the position of the cartridge.

[0050] In this case, the stick detection sensor and / or cartridge detection sensor can be implemented as an inductive sensor, a capacitive sensor, a resistive sensor, or a Hall sensor (or Hall IC) using the Hall effect.

[0051] For example, if the aerosol generating device 100 includes a cartridge, the sensor module 150 may include a sensor for detecting the type of cartridge (hereinafter referred to as a "type detection sensor"). In this case, the type detection sensor may be implemented as a push-button switch, a force sensor for detecting the magnitude of a force applied in a predetermined direction, etc.

[0052] For example, sensor module 150 may include a voltage sensor for sensing the voltage applied to a component (e.g., battery 160) disposed in aerosol generating apparatus 100 and / or a current sensor for sensing current.

[0053] Battery 160 can supply power for the operation of aerosol generating apparatus 100 under the control of controller 170. Battery 160 can also supply power to other components disposed in aerosol generating apparatus 100. For example, battery 160 can supply power to a communication module included in communication interface 110, an output device included in input / output interface 120, and a heater included in aerosol generating module 130.

[0054] Battery 160 can be a rechargeable battery or a disposable battery. For example, battery 160 can be a lithium-ion (Li-ion) battery, a lithium polymer (Li-polymer) battery, or a lithium-ion phosphate battery. However, this disclosure is not limited thereto. For example, battery 160 can be a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, etc.

[0055] The aerosol generating apparatus 100 may also include a battery protection circuit module (PCM) (not shown) as a circuit for protecting the battery 160. The battery protection circuit module (PCM) may be disposed adjacent to the upper surface of the battery. For example, to prevent overcharging and over-discharging of the battery 160, the battery protection circuit module (PCM) may disconnect the electrical path to the battery 160 when a short circuit occurs in the circuit connected to the battery 160, when an overvoltage is applied to the battery 160, or when an overcurrent flows through the battery 160.

[0056] The aerosol generating device 100 may also include a charging terminal that receives power supplied from an external source. For example, the charging terminal may be formed on one side of the main body of the aerosol generating device 100. The aerosol generating device 100 can use the power supplied through the charging terminal to charge the battery 160. In this case, the charging terminal may be configured as a wired terminal for USB communication, a spring pin, etc.

[0057] The aerosol generating apparatus 100 may also include a power terminal (not shown) to which power supplied from an external source is input. For example, a power cord may be connected to the power terminal located on one side of the main body of the aerosol generating apparatus 100. The aerosol generating apparatus 100 can use the power supplied through the power cord connected to the power terminal to charge the battery 160. In this case, the power terminal may be a wired terminal for USB communication.

[0058] The aerosol generating device 100 can wirelessly receive power supplied from an external source via the communication interface 110. For example, the aerosol generating device 100 can use an antenna included in a communication module for wireless communication to wirelessly receive power. The aerosol generating device 100 can use the wirelessly supplied power to charge the battery 160.

[0059] The controller 170 can control the overall operation of the aerosol generating apparatus 100. The controller 170 can be connected to each component disposed in the aerosol generating apparatus 100. The controller 170 can send signals to each component and / or receive signals from each component, thereby controlling the overall operation of each component.

[0060] The controller 170 may include at least one processor. The controller 170 may use the processor included therein to control the overall operation of the aerosol generating apparatus 100. Here, the processor may be a general-purpose processor such as a central processing unit (CPU). Of course, the processor may be a special-purpose device such as an application-specific integrated circuit (ASIC), or any of other hardware-based processors.

[0061] The controller 170 can perform any of the multiple functions of the aerosol generating device 100. For example, the controller 170 can perform any of the multiple functions of the aerosol generating device 100 (e.g., preheating function, heating function, charging function, and cleaning function) based on the status of each component set in the aerosol generating device 100 and user commands received through the input / output interface 120.

[0062] The controller 170 can control the operation of each component in the aerosol generating device 100 based on data stored in the memory 140. For example, the controller 170 can control the supply of a predetermined amount of power from the battery 160 to the aerosol generating module 130 within a predetermined time period based on data about temperature profiles and the user's inhalation patterns stored in the memory 140.

[0063] The controller 170 can use a suction sensor included in the sensor module 150 to determine whether suction has occurred or not. For example, the controller 170 can check for temperature changes, flow rate changes, pressure changes, and voltage changes in the aerosol generating device 100 based on values ​​sensed by the suction sensor. The controller 170 can determine whether suction has occurred or not based on values ​​sensed by the suction sensor.

[0064] The controller 170 can control the operation of each component in the aerosol generating apparatus 100 based on whether suction occurs or not and / or the number of suction cycles. For example, the controller 170 can perform control to change or maintain the temperature of the heater based on the temperature profile stored in the memory 140.

[0065] The controller 170 can perform control to interrupt the power supply to the heater according to predetermined conditions. For example, the controller 170 can perform control to interrupt the power supply to the heater when the stick is removed, when the cartridge is disassembled, when the number of puffs reaches a predetermined maximum number of puffs, when no puff is detected during a predetermined time period or longer, or when the remaining capacity of the battery 160 is less than a predetermined value.

[0066] The controller 170 can calculate the remaining capacity relative to the fully charged capacity of the battery 160. For example, the controller 170 can calculate the remaining capacity of the battery 160 based on values ​​sensed by voltage sensors and / or current sensors included in the sensor module 150.

[0067] The controller 170 may use at least one of pulse width modulation (PWM) or proportional-integral-derivative (PID) methods to perform control so that power is supplied to the heater.

[0068] For example, controller 170 can use a PWM method to perform control so that current pulses with a predetermined frequency and a predetermined duty cycle are supplied to the heater. In this case, controller 170 can control the electrical force supplied to the heater by adjusting the frequency and duty cycle of the current pulses.

[0069] For example, controller 170 can determine the target temperature to be controlled based on a temperature curve. In this case, controller 170 can use a PID method to control the electrical power supplied to the heater. The PID method is a feedback control method that uses the difference between the heater temperature and the target temperature, a value obtained by integrating the difference with respect to time, and a value obtained by differentiating the difference with respect to time.

[0070] Although PWM and PID methods have been described as examples of methods for controlling the power supply to the heater, this disclosure is not limited thereto, and any of a variety of control methods such as proportional-integral (PI) or proportional-derivative (PD) methods may be employed.

[0071] Furthermore, the controller 170 can perform control to supply power to the heater according to predetermined conditions. For example, when a cleaning function for cleaning the space in which the rod 201 is inserted is selected by a command input by the user through the input / output interface 120, the controller 170 can perform control to supply a predetermined amount of power to the heater.

[0072] Reference Figure 2 According to the embodiments, the aerosol generating apparatus 100 may include a main body 210 and a cartridge 220. The main body 210 may support the cartridge 220, and the cartridge 220 may contain an aerosol generating substance.

[0073] According to one embodiment, the cartridge 220 can be configured to be detachably mounted to the body 210. For example, the cartridge 220 can be mounted to the body 210 such that at least a portion of the cartridge 220 is inserted into the internal space formed by the outer casing 215 of the body 210.

[0074] The main body 210 can be configured to introduce external air into the main body 210 while the cartridge 220 is inserted therein. Here, the external air introduced into the main body 210 can flow into the user's mouth via the cartridge 220.

[0075] The controller 170 can use a cartridge detection sensor included in the sensor module 150 to determine whether the cartridge 220 is in an installed or disassembled state. For example, the cartridge detection sensor can send a pulse current through a first terminal in which the body 210 and the cartridge 220 are in contact. In this case, the controller 170 can determine whether the cartridge 220 is in a connected state based on whether a pulse current is received through a second terminal. In this case, the first and second terminals can be implemented using spring pins or the like.

[0076] The cartridge 220 may include a reservoir 221 configured to contain aerosol-generating material and / or a heater 223 configured to heat the aerosol-generating material in the reservoir 221. For example, a liquid delivery element impregnated with (containing) aerosol material may be disposed inside the reservoir 221. Conductive tracks of the heater 223 may be formed in a structure wound around the liquid delivery element. In this case, when the liquid delivery element is heated by the heater 223, an aerosol may be generated. Here, the liquid delivery element may include a core made of, for example, cotton fibers, ceramic fibers, glass fibers, or porous ceramics.

[0077] The cartridge 220 may include a mouthpiece 225. Here, the mouthpiece 225 may be a portion to be inserted into the user's mouth. The mouthpiece 225 may have a discharge port through which aerosol is discharged to the outside during inhalation.

[0078] Reference Figure 3 The aerosol generating apparatus 100 according to the embodiment may include a cartridge 220 configured to allow insertion of a stick 300 into an internal space 230. For example, the cartridge 220 may include an internal space formed by an inner wall extending in a circumferential direction along the direction of insertion of the stick 300. In this case, the internal space can be formed by opening the inner side of the inner wall upwards or downwards. The stick 300 can be inserted into the internal space formed by the inner wall.

[0079] The internal space into which the rod 300 is inserted can be formed in a shape corresponding to the shape of a portion of the rod 300 inserted into the internal space. For example, when the rod 300 is formed in a cylindrical shape, the internal space can be formed in a cylindrical shape.

[0080] When the rod 300 is inserted into the internal space, the outer surface of the rod 300 can be surrounded by and contact the inner wall.

[0081] Stick 300 can be similar to a conventional combustible cigarette. For example, Stick 300 can be divided into a first part including aerosol-generating material and a second part including a filter, etc. Alternatively, the aerosol-generating material can be included in the second part of Stick 300. For example, a flavoring substance made in the form of granules or capsules can be inserted into the second part.

[0082] The entire first part is inserted into the internal space 230 of the cartridge 220, and the second part may be exposed to the outside. Alternatively, only a portion of the first part may be inserted into the internal space 230 of the cartridge 220, or a portion of both the first and second parts may be inserted.

[0083] The user can inhale the aerosol while biting down on the second part. The aerosol generated by the heater 223 can pass through the first and second parts of the rod 300 and be delivered to the user's mouth. At this time, as the aerosol passes through the rod 300, the material contained in the rod 300 can be added to the aerosol. The aerosol containing the injected material can be inhaled into the user's oral cavity through one end of the rod 300.

[0084] Reference Figure 4 According to the embodiment, the aerosol generating apparatus 100 may include a main body 210 supporting a cartridge 220 and a cartridge 220 containing an aerosol generating substance. The main body 210 may be configured to allow a rod 300 to be inserted into its internal space 400.

[0085] The aerosol generating device 100 may include a first heater for heating the aerosol generating material stored in the cartridge 220. For example, when a user holds one end of the stick 300 in their mouth to inhale the aerosol, the aerosol generated by the first heater can pass through the stick 300. At this time, as the aerosol passes through the stick 300, tobacco material can be added to the aerosol. The aerosol containing tobacco material can be inhaled into the user's mouth through one end of the stick 300.

[0086] Alternatively, according to another embodiment, the aerosol generating apparatus 100 may include a first heater for heating aerosol generating material stored in the cartridge 220 and a second heater for heating the rod 300 inserted into the body 210. For example, the aerosol generating apparatus 100 can generate aerosols by heating the aerosol generating material stored in the cartridge 220 and the rod 300 using the first heater and the second heater, respectively.

[0087] Figure 5 This is a flowchart of an operation method of an aerosol generating apparatus according to another embodiment of the present disclosure. Figures 6 to 15 This is a diagram illustrating an aerosol generating apparatus according to an embodiment of the present disclosure.

[0088] Reference Figure 5 In operation S510, the aerosol generating device 100 can use a cartridge detection sensor included in the sensor module 150 to detect the installation of the cartridge 220 onto the body 210. For example, the aerosol generating device 100 can send a predetermined current through a first terminal of the body 210 that contacts the cartridge 220 to monitor whether the cartridge 220 has been installed. At this time, when a current corresponding to the predetermined current is received through a second terminal of the body 210 that contacts the cartridge 220, the aerosol generating device 100 can determine that the cartridge 220 has been installed.

[0089] Each of the first and second terminals may include a power terminal through which power is transmitted from the body 210 to the cartridge. For example, power supplied from the battery 160 included in the body 210 may be transmitted to the cartridge 220 via the first and second terminals, and the heater 223 included in the cartridge 220 may be heated by the power transmitted via the first and second terminals.

[0090] In operation S520, the aerosol generating device 100 can use a type detection sensor included in the sensor module 150 to determine the type of the cartridge 220 installed in the body 210. For example, the aerosol generating device 100 can determine the type of the cartridge 220 installed in the body 210 from a variety of preset types based on the value sensed by the type detection sensor.

[0091] Here, the type of the cartridge 220 can be preset differently depending on the type, contents, or state of the substance contained in the storage 221 of the cartridge 220, whether the stick 300 can be inserted into it, or the type of stick 300 that can be inserted into it.

[0092] During operation S530, the aerosol generating device 100 can determine a mode corresponding to the type of the cartridge 220. For example, the aerosol generating device 100 can determine the mode corresponding to the type of the cartridge 220 from a variety of preset modes.

[0093] The aerosol generating device 100 can output information about the type of the cartridge 220 installed in the main body 210 via an output device included in the input / output interface 120. For example, the aerosol generating device 100 can output an image corresponding to the type of cartridge 220 installed in the main body 210 via a display.

[0094] In operation S540, the aerosol generating device 100 can perform operations corresponding to the determined mode.

[0095] The aerosol generating apparatus 100 can generate aerosols by controlling its components according to a determined pattern. For example, the aerosol generating apparatus 100 can determine a temperature profile corresponding to a pattern from a plurality of temperature profiles stored in the memory 140, and can adjust the temperature of the heater 223 based on the temperature profile corresponding to the pattern.

[0096] When multiple heaters are provided, the aerosol generating device 100 can supply power to multiple heaters according to a determined mode. For example, when the aerosol generating device 100 includes a first heater for heating the aerosol generating material stored in the smoke cartridge 220 and a second heater for the heating rod 300, the aerosol generating device 100 can supply power to only the first heater when the determined mode is the first mode, and can supply power to both the first heater and the second heater when the determined mode is the second mode.

[0097] See below for reference. Figures 6 to 15 This describes the determination of the type of smoke cartridge 220. In the following text, it can be based on... Figures 6 to 15 The orientation of the aerosol generating device 100 is defined using an orthogonal coordinate system. In this system, the x-axis can be defined as the horizontal direction of the aerosol generating device 100. Here, based on the origin, the +x-axis can be to the right, and the -x-axis can be to the left. The y-axis can be defined as the vertical direction of the aerosol generating device 100. Here, based on the origin, the +y-axis can be upward, and the -y-axis can be downward.

[0098] Reference Figure 6 The main body 210 may include a housing 215 having an inner wall forming an insertion space 600 therein, into which the cartridge 220 is inserted.

[0099] The inner wall may be composed of a plurality of inner surfaces that contact the cartridge 220 inserted into the insertion space 600. For example, the inner wall may be composed of a bottom surface 601 supporting the lower end of the cartridge 220 and an inner wall surface 603 supporting the side surfaces of the cartridge 220.

[0100] The type detection sensor 610 can be positioned adjacent to the insertion space 600.

[0101] The type detection sensor 610 can be disposed in a region of the bottom surface 601. For example, the type detection sensor 610 can be configured to protrude a predetermined height h1 from a region of the bottom surface 601 toward the insertion space 600.

[0102] The type detection sensor 610 may include: a contact portion 611 that contacts a cartridge 220 inserted into an insertion space 600; a signal generator 613 for generating a signal; and / or an elastic member 615 for elastically supporting the contact portion 611 in the vertical direction.

[0103] The type detection sensor 610 can be implemented as a force sensor, which outputs a signal corresponding to the magnitude of the force applied in a predetermined direction. For example, at least a portion of the contact portion 611 can be moved into the internal space 605 where the type detection sensor 610 is disposed by a force applied to it in the downward direction, and the signal generator 613 can generate a signal corresponding to the magnitude of the force used to move the contact portion 611. In this case, the signal generated by the signal generator 613 can be output as a signal indicating the type of the cartridge 220.

[0104] Although the force sensor is described below as an example of a type detection sensor 610, this disclosure is not limited thereto. The type detection sensor 610 can be implemented as a push-button switch.

[0105] When the cartridge 220 is installed or removed in a vertical direction, the inner wall surface 603 can be formed to extend vertically, so that the upper part of the insertion space 600 opens. When the cartridge 220 is inserted through the open upper part of the insertion space 600, the cartridge 220 can be surrounded by the bottom surface 601 and the inner wall surface 603. The cartridge 220 can be in close contact with the inner wall surface 603.

[0106] The cross-sectional shape of the insertion space 600, which is surrounded by the inner wall surface 603, in the horizontal direction can correspond to the cross-sectional shape of the cartridge 220 in the horizontal direction. For example, when the cross-sectional shape of the cartridge 220 in the horizontal direction is rectangular, the cross-sectional shape of the insertion space 600 in the horizontal direction can also be rectangular.

[0107] Reference Figure 7 The cartridge 220 may include multiple outer surfaces. For example, the cartridge 220 may include a lower surface 711 that contacts the bottom surface 601 of the inner wall of the housing 215, a side surface 713 that contacts the inner wall surface 603 of the inner wall, and / or an upper surface 714 that covers the upper end of the space surrounded by the side surface 713.

[0108] The feature portion 720 having a shape corresponding to the type of the cartridge 220 can be formed in any of the multiple outer surfaces included in the cartridge 220.

[0109] When the cartridge 220 is inserted into the insertion space 600 in the downward direction, the feature portion 720 can be formed in the lower surface 711, which is the outer surface oriented in the downward direction.

[0110] The feature portion 720 can be formed such that a region 712 of the lower surface 711 is recessed in the cartridge 220. The depth to which the region 712 of the lower surface 711 is recessed in the cartridge 220 can correspond to the type of the cartridge 220.

[0111] Referring to reference numerals 701, 702, and 703 in the accompanying drawings, the depth to which region 712 of the lower surface 711 is recessed in the cartridge 220 can be “h1” when the type of cartridge 220 is a first type (e.g., cartridge 220a), “h2” when the type of cartridge 220 is a second type (e.g., cartridge 220b), and “h3” when the type of cartridge 220 is a third type (e.g., cartridge 220c).

[0112] The cross-sectional shape of the feature portion 720 in the horizontal direction can correspond to the cross-sectional shape of the portion of the type detection sensor 610 that contacts the cartridge 220 in the horizontal direction. For example, when the contact space 725 formed by making the region 712 of the lower surface 711 concave in the inward direction has a cylindrical shape, the cross-sectional shape of the portion of the type detection sensor 610 that contacts the cartridge 220 in the horizontal direction can be circular.

[0113] Reference Figure 8 When the cartridge 220 is inserted into the insertion space 600, the bottom surface 601 of the inner wall and the lower surface 711 of the cartridge 220 can come into contact with each other, and the type detection sensor 610 can come into contact with the feature portion 720 formed in the lower surface 711 of the cartridge 220.

[0114] When the cartridge 220 is inserted into the insertion space 600, the contact portion 611 of the type detection sensor 610 can be inserted into the contact space 725 in the feature portion 720. At this time, the upper end of the contact portion 611 can contact the area 712 of the lower surface 711.

[0115] The magnitude of the force applied to the contact portion 611 in the downward direction can correspond to the depth of the recess of the region 712 of the lower surface 711 in the cartridge 220 (i.e., the height of the contact space 725).

[0116] Referring to reference numeral 801 in the attached drawing, when the height of the contact portion 611 is “h1”, when the first type of smoke cartridge 220a is installed on the main body 210, the magnitude of the force applied to the contact portion 611 in the downward direction can be zero because the height of the contact space 725 is “h1”.

[0117] Referring to reference numerals 802 and 803 in the accompanying drawings, when a second type of cartridge 220b or a third type of cartridge 220c is installed onto the body 210, the magnitude of the force applied to the contact portion 611 in the downward direction can be greater than zero because the height of the contact space 725 is lower than "h1".

[0118] When the third type of cartridge 220c is installed into the main body 210, the contact portion 611 can move a longer distance in the downward direction, and the magnitude of the force applied to the contact portion 611 in the downward direction can be greater than the magnitude of the force applied to the contact portion 611 in the downward direction when the second type of cartridge 220b is installed into the main body 210. In other words, as the difference between the height of the contact portion 611 and the height of the contact space 725 increases, a larger force can be applied to the contact portion 611 in the downward direction.

[0119] As described above, when the height of the contact space 725 varies depending on the type of cartridge 220, the magnitude of the force applied to the type detection sensor 610 in the downward direction can vary. Furthermore, since the signal output from the type detection sensor 610 varies depending on the magnitude of the force sensed by the type detection sensor 610, the controller 170 of the aerosol generating device 100 can determine the type of cartridge 220 installed on the body 210 based on the signal output from the type detection sensor 610.

[0120] In addition, the cartridge 220 may have at least one guide slit 730 formed on at least one of its plurality of outer surfaces in the direction in which the cartridge 220 is installed or removed.

[0121] Additionally, the housing 215 may include at least one inner peripheral protrusion 620 formed on at least one of a plurality of inner surfaces forming an inner wall along the direction in which the cartridge 220 is installed or removed.

[0122] In this configuration, when the cartridge 220 is inserted into the insertion space 600, the inner peripheral protrusion 620 of the casing 215 can be inserted into the guide slit 730 in the cartridge 220. Therefore, the user can confirm that the cartridge 220 is properly installed (inserted in the correct direction).

[0123] Reference Figure 9 and Figure 10 The main body 210 may include multiple types of detection sensors 610a and 610b disposed adjacent to the insertion space 600.

[0124] Multiple type detection sensors 610a and 610b can be arranged in a spaced-apart manner in a region of the bottom surface 601. For example, each of the multiple type detection sensors 610a and 610b can be configured to protrude a predetermined height h1 from a region of the bottom surface 601 toward the insertion space 600. In this case, the protruding heights of type detection sensor 610a and type detection sensor 610b can be different from each other.

[0125] The type detection sensor 610a may include a contact portion 611a of the contact cartridge 220, a signal generator 613a for generating a signal, and / or an elastic member 615a for elastically supporting the contact portion 611a in the vertical direction. The type detection sensor 610b may include a contact portion 611b of the contact cartridge 220, a signal generator 613b for generating a signal, and / or an elastic member 615b for elastically supporting the contact portion 611b in the vertical direction.

[0126] When the type of cartridge 220 is a first type (e.g., cartridge 220a), indicated by reference numeral 1001, a feature portion 720 may be formed in the lower surface 711 of the cartridge 220. When the type of cartridge 220 is a fourth type (e.g., cartridge 220d), indicated by reference numeral 1002, multiple feature portions 720a and 720b may be formed in the lower surface 711 of the cartridge 220.

[0127] When the type of cartridge 220 is the fourth type (e.g., cartridge 220d), multiple regions 712a and 712b of the lower surface 711 can be recessed into the cartridge 220 to a predetermined depth h1 to form multiple feature portions 720a and 720b, respectively.

[0128] When the first type of cartridge 220a is installed into the body 210, which includes multiple types of detection sensors 610a and 610b, a force can be applied downwards to the first contact portion 611a of the first type of detection sensor 610a via the lower surface 711 of the cartridge 220. However, since the second contact portion 611b of the second type of detection sensor 610b is inserted into the contact space 725 in the feature portion 720 having a height corresponding to the height of the second contact portion 611b, the magnitude of the force applied to the second contact portion 611b can be zero.

[0129] When the fourth type of cartridge 220d is installed into the body 210 which includes multiple types of detection sensors 610a and 610b, the first contact portion 611a and the second contact portion 611b can be inserted into the first contact space 725a and the second contact space 725b respectively, so the magnitude of the force applied to the first contact portion 611a and the magnitude of the force applied to the second contact portion 611b can be zero.

[0130] As described above, when the aerosol generating device 100 includes multiple types of detection sensors 610a and 610b, the controller 170 of the aerosol generating device 100 can determine the type of the cartridge 220 installed on the body 210 based on the signals output from the multiple types of detection sensors 610a and 610b.

[0131] Reference Figure 11 and Figure 12 When the cartridge 220 is inserted in the vertical direction, the type detection sensor 610 can be set in the space formed by recessing a region of the bottom surface 601 of the housing 215 in the inward direction of the housing 215 to a predetermined depth.

[0132] Additionally, the cartridge 220 may include a feature portion 720 formed such that a region 712 of the lower surface 711 protrudes a predetermined height in the direction in which the cartridge 220 is inserted. The height to which the region 712 of the lower surface 711 protrudes may correspond to the type of cartridge 220.

[0133] Referring to reference numerals 1201 and 1202 in the accompanying drawings, the height of region 712 of the lower surface 711 protruding in the direction in which the cartridge 220 is inserted can be “h4” when the type of cartridge 220 is type 5 (e.g., cartridge 220e) and can be “h5” when the type of cartridge 220 is type 6 (e.g., cartridge 220f).

[0134] Reference Figure 13 When the cartridge 220 is inserted into the insertion space 600, the upper end of the contact portion 611 of the type detection sensor 610 can contact the area 712 of the lower surface 711.

[0135] The magnitude of the force applied to the contact portion 611 in the downward direction can correspond to the height of the region 712 of the lower surface 711 protruding in the direction in which the cartridge 220 is inserted.

[0136] When the cartridge 220 is inserted into the insertion space 600, the contact portion 611 of the type detection sensor 610 can move in the downward direction by a distance corresponding to the height of the protrusion of the area 712 of the lower surface 711 of the cartridge 220.

[0137] When the fifth type of cartridge 220e is installed into the main body 210, the contact portion 611 can move a shorter distance in the downward direction, and the magnitude of the force applied to the contact portion 611 in the downward direction can be less than the magnitude of the force applied to the contact portion 611 in the downward direction when the sixth type of cartridge 220f is installed into the main body 210. In other words, as the height of the region 712 protruding from the lower surface 711 of the cartridge 220 increases, a larger force can be applied to the contact portion 611 in the downward direction.

[0138] Reference Figure 14 When the cartridge 220 is installed or removed in a horizontal direction, a portion of the inner wall surface 603 of the outer casing 215 can be cut off, so that one side surface of the insertion space 1410 can be opened to the outside. In this case, when the cartridge 220 is inserted into the insertion space 1410 through its opened side surface, the cartridge 220 can be surrounded by the bottom surface 601 and the remaining portion of the inner wall surface 603, excluding the cut portion.

[0139] The type detection sensor 610 can be disposed in a region of the inner wall surface 603. For example, the type detection sensor 610 can be configured to protrude a predetermined height w1 from the region of the inner wall surface 603 toward the insertion space 600.

[0140] When the cartridge 220 is inserted into the insertion space 1410, at least a portion of the contact portion 611 can be moved into the internal space 605 where the type detection sensor 610 is disposed by a force applied to it in the rightward direction, and the signal generator 613 can generate a signal corresponding to the magnitude of the force that moves the contact portion 611 in the rightward direction. At this time, the signal generated by the signal generator 613 can be output as a signal indicating the type of the cartridge 220.

[0141] Reference Figure 15 When the cartridge 220 is inserted into the insertion space 1410 in the right direction, the feature portion 720 can be formed in a region of the side surface 713 oriented in the right direction.

[0142] The feature portion 720 can be formed such that a region 715 of the side surface 713 is recessed in the cartridge 220. The depth to which the region 715 of the side surface 713 is recessed in the cartridge 220 can correspond to the type of the cartridge 220.

[0143] Referring to reference numerals 1501 and 1502 in the accompanying drawings, the depth of the recess of region 715 of the side surface 713 in the cartridge 220 can be “w1” when the type of cartridge 220 is type 5 (e.g., cartridge 220e) and can be “w2” when the type of cartridge 220 is type 6 (e.g., cartridge 220f).

[0144] The cross-sectional shape of the feature portion 720 in the vertical direction can correspond to the cross-sectional shape of the portion of the type detection sensor 610 that contacts the cartridge 220 in the vertical direction. For example, when the contact space 725 formed by making the region 715 of the side surface 713 concave in the inward direction has a cylindrical shape, the cross-sectional shape of the portion of the type detection sensor 610 that contacts the cartridge 220 in the vertical direction can be circular.

[0145] As described above, according to at least one embodiment of the present disclosure, the type of cartridge 220 is determined based on the physical contact between a feature portion 720 formed in the outer surface of the cartridge 220 connected to the body 210 and a type detection sensor 610 for detecting the type of cartridge 220. Therefore, unlike electrical methods using capacitance or optical methods using light, the type of cartridge 220 can be accurately determined regardless of environmental factors.

[0146] According to at least one embodiment of this disclosure, the mode can be changed and set differently depending on the type of cartridge 220, so that the user can use various types of cartridges with a single body 210.

[0153] In addition, according to another aspect of this disclosure, the type detection sensor 610 may be a force sensor configured to output a signal corresponding to the magnitude of the force applied in a predetermined direction.

[0155] Additionally, according to another aspect of this disclosure, the aerosol generating apparatus may further include: a heater 223 configured to heat the aerosol generating substance; and a controller 170. The controller 170 can determine the type of the cartridge 220 based on a signal received from the type detection sensor 610, and can control the heater 223 according to a pattern determined from a variety of modes.

[0156] Additionally, according to another aspect of this disclosure, the aerosol generating apparatus may further include a memory 140 configured to store a plurality of temperature profiles therein. The controller 170 can determine a temperature profile corresponding to a determined pattern from the plurality of temperature profiles and can control the temperature of the heater 223 based on the determined temperature profile.
