[0044] Figure 1 is an illustration of a configuration of an aerosol generating device according to an embodiment.

[0045] Reference Figure 1 The aerosol generating device 100 may include a medium portion 110 , a vaporizer 120 , a processor 130 , a battery 140 , a mouthpiece 150 , an input portion 160 , an input circuit 170 , a dial gear 181 , and a medium portion gear 182 .

[0046] Figure 1 Only some of the components of the aerosol generating device 100 that are particularly relevant to this embodiment are shown. Therefore, a person skilled in the art will understand that, in addition to including Figure 1 In addition to the components shown in FIG, the aerosol generating device 100 may further include other components.

[0047] In addition, the internal structure of the aerosol generating device 100 is not limited to Figure 1 In other words, the medium portion 110, vaporizer 120, processor 130, battery 140, mouthpiece 150, input portion 160, input circuit 170, turntable gear 181, and medium portion gear 182 may be arranged in different ways depending on the design of the aerosol generating device 100. For example, the input circuit 170 is shown as being combined with the input portion 160, but may also be combined with the turntable gear 181.

[0048] according to Figure 1 The aerosol generating device 100 of the embodiment can generate aerosol by using a resistance heating method, an induction heating method, an ultrasonic vibration method, etc. Figure 1 The aerosol generating device 100 of the embodiment is a device for providing aerosol to a user.

[0049] The medium portion 110 may include at least one chamber. When the medium portion 110 includes a plurality of chambers, the chambers may be separated by a separator to be independent of each other. The chamber may store a fragrance material that will be passed through by the aerosol. Figure 5a and Figure 5b Single chambers and multiple chambers are described in detail.

[0050] The aroma material may be in a solid state, and for example, the aroma material may include granules, i.e., a powder or a group of small-sized particles. However, the present disclosure is not limited thereto. For example, the aroma material may be in the form of a capsule, and the aroma material may also be in the form of chopped plant leaves.

[0051] Fragrance materials may include ingredients that can provide various aromas or flavors to the user.

[0052] The flavor material may include, for example: a tobacco-containing material comprising volatile tobacco flavor components; additives such as flavorants, humectants and / or organic acids; flavoring materials such as menthol or humectants; any one of plant extracts, spices, flavoring and vitamin mixtures, or a combination thereof.

[0053] The flavoring material may include, but is not limited to, menthol, peppermint, spearmint oil, and various fruity ingredients.

[0054] The flavoring material may include a vitamin mixture, and the vitamin mixture may include at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto.

[0055] The media portion 110 may be arranged to rotate relative to the vaporizer 120. When the media portion 110 includes a plurality of chambers, the chambers may be sequentially arranged apart from each other in the rotation direction of the media portion 110.

[0056] One or more chambers may be included in the media portion 110. For example, the media portion 110 may have a cylindrical shape, and a single cylindrical chamber may be disposed inside the media portion 110. Alternatively, multiple chambers may be disposed on the exterior of the media portion 110. For example, the top surface of the media portion 110 may be divided into four chambers. The media portion 110 may be rotated in a clockwise or counterclockwise direction relative to the longitudinal axis of the aerosol generating device 100. As the media portion 110 rotates, the relative positions of the multiple chambers 110 relative to the vaporizer 120 may change.

[0057] The vaporizer 120 can generate an aerosol by heating an aerosol-generating substance (e.g., a liquid composition), and the generated aerosol can be provided to the user through the chamber of the medium portion 110. When the medium portion 110 includes the plurality of chambers, the aerosol can pass through one of the plurality of chambers. In other words, the aerosol generated by the vaporizer 120 can move along the airflow channel of the aerosol generating device 100, and the airflow channel can be configured such that the aerosol generated by the vaporizer 120 can be provided to the user through one of the plurality of chambers included in the medium portion 110.

[0058] The vaporizer 120 may generate an aerosol by changing the phase of a liquid composition into a gas phase. The aerosol may indicate a mixture of air and particles generated by vaporizing the liquid composition.

[0059] For example, the vaporizer 120 may include a liquid storage portion, a liquid delivery element, and a heating element, but is not limited thereto. For example, the liquid storage portion, the liquid delivery element, and the heating element may also be included in the aerosol generating device 100 as separate modules.

[0060] The liquid storage portion can store a liquid composition. The liquid composition can include a material in a liquid or gel state. The liquid composition can be kept in the liquid storage portion in a state of being immersed in a porous material such as a sponge or cotton.

[0061] For example, the liquid composition may include a liquid containing a tobacco-containing material having a volatile tobacco aroma component, or may include a liquid containing a non-tobacco material. The liquid storage portion may be formed to be attached to / detached from the vaporizer 120, or the liquid storage portion may be formed integrally with the vaporizer 120. When the liquid storage portion is formed integrally with the vaporizer 120, the vaporizer 120 may be coupled to the aerosol generating device 100 so as to be attachable to / detachable from the aerosol generating device 100.

[0062] For example, the liquid composition may include water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. Flavoring agents may include, but are not limited to, menthol, peppermint, spearmint oil, and various fruity ingredients. Flavoring agents may include ingredients that can provide a variety of aromas or flavors to the user. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. In addition, the liquid composition may include an aerosol-forming substance, such as glycerin and propylene glycol.

[0063] The liquid transport element can transport the liquid composition of the liquid storage portion to the heating element. For example, the liquid transport element can include a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited thereto.

[0064] The heating element is an element used to heat the liquid composition being transported by the liquid transport element. For example, the heating element may include, but is not limited to, a metal heating wire, a metal hot plate, a ceramic heater, or the like. Furthermore, the heating element may include a conductive wire, such as a nichrome wire. The heating element may be arranged in contact with or adjacent to the liquid transport element, or the heating element may be arranged in a structure wrapped around the liquid transport element. The heating element may be surrounded by a liquid storage portion.

[0065] The heating element can be heated by an electric current supply device, and the heating element can transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. However, this is not necessarily limited to this. The vaporizer 120 can generate an aerosol, for example, by an ultrasonic method or an induction heating method.

[0066] The vaporizer 120 may be referred to as a cartridge, a cartomizer, or an atomizer, but is not limited thereto.

[0067] The vaporizer 120 and the media portion 110 may be combined to be rotatable relative to each other. For example, the vaporizer 120 may be fixed, and the chamber of the media portion 110 may be rotatable relative to the vaporizer 120.

[0068] The vaporizer 120 may be arranged in fluid communication with one of the chambers such that an aerosol generated from the vaporizer 120 may pass through only the one of the plurality of chambers in fluid communication with the vaporizer 120 .

[0069] The vaporizer 120 may include a discharge port that extends in the longitudinal direction of the aerosol generating device 100 and delivers the aerosol to the medium portion 110. The liquid storage portion included in the vaporizer 120 delivers the aerosol generated by the heating element to the discharge port. Therefore, the aerosol provided from the liquid storage portion is delivered to the medium portion 110 through the discharge port.

[0070] When the vaporizer 120 is coupled to the media portion 110, the relative positions of the vaporizer 120 and the media portion 110 can be changed, and thus, different portions of the single chamber of the media portion 110 can be aligned with the exhaust port of the vaporizer 120. Alternatively, when the relative positions of the vaporizer 120 and the media portion 110 are changed, at least one of the plurality of chambers can be aligned with the exhaust port of the vaporizer 120. Thus, the aerosol emitted from the exhaust port of the vaporizer 120 passes through the portion of the single chamber of the media portion 110 corresponding to the exhaust port, or the aerosol emitted from the exhaust port of the vaporizer 120 passes through the fragrance material stored in the chamber corresponding to the exhaust port of the plurality of chambers of the media portion 110. When the aerosol passes through the fragrance material, the characteristics of the aerosol can be changed.

[0071] When the discharge port is formed so that aerosol passes the bottom surface of the medium portion 110, even when comprising a large amount of fragrance materials, only the migration amount of the fragrance material can increase and migration may not last long enough. Therefore, when the discharge port is formed so that aerosol only passes a part of a single chamber, the migration duration of the fragrance material can increase. In the case of multiple chambers, when the discharge port is formed so that aerosol passes a chamber in the multiple chambers, the migration duration of the fragrance material can increase by the multiple of the number of chambers. Along with the migration duration of the fragrance material can increase, the amount of the liquid composition used together with the fragrance material can also increase. Therefore, the fragrance material can continue to migrate for a long time when not replacing the medium portion 110. In addition, when the different parts of a single chamber or the multiple chambers comprise different fragrance materials, the fragrance of the aerosol can change.

[0072] The aerosol generating device 100 may include a mouthpiece 150 to be placed in the user's mouth. Aerosol generated from the vaporizer 120 may be transferred to the outside of the aerosol generating device 100 through the mouthpiece 150. In an example, the mouthpiece 150 may be formed at an end portion of the aerosol generating device 100.

[0073] The vaporizer 120, the medium portion 110, and the mouthpiece 150 can be integrally combined to form an aerosol-generating assembly. Depending on the embodiment, the aerosol-generating assembly can have various shapes, such as a rectangular parallelepiped or a cube. The aerosol-generating assembly can be detachably combined with the aerosol-generating device 100. When the aerosol-generating assembly is inserted into the aerosol-generating device 100, the aerosol-generating device 100 can generate an aerosol by operating the vaporizer 120. The aerosol generated by the vaporizer 120 is transmitted to the user through the medium portion 110.

[0074] The processor 130 may generally control the operation of the aerosol generating device 100. Specifically, the processor 130 may control not only the operation of the battery 140 and the vaporizer 120, but also the operation of other components included in the aerosol generating device 100. In addition, the processor 130 may check the status of each of the components of the aerosol generating device 100 to determine whether the aerosol generating device 100 is capable of operating.

[0075] The processor 130 may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing programs that can be executed in the microprocessor. In addition, those skilled in the art will appreciate that other types of implementations may also be employed.

[0076] The battery 140 provides power for the operation of the aerosol generating device 100. For example, the battery 140 can provide power for heating the vaporizer 120 and can provide power for operating the processor 130. In addition, the battery 140 can provide power for operating a display, a sensor, a motor, etc. installed in the aerosol generating device 100.

[0077] Will refer to it later Figure 2 and Figure 3 The operations of the input section 160, the input circuit 170, the turntable gear 181, and the medium section gear 182 will be described.

[0078] Figure 2 is a diagram for describing a method of partially rotating a medium according to an embodiment.

[0079] Reference Figure 2 , showing the media section 110, the input section 160, the turntable gear 181 and the media section gear 182. Figure 2 The dielectric portion 110 in may correspond to Figure 1 Therefore, repeated description of the dielectric portion 110 is omitted.

[0080] The input portion 160, the turntable gear 181, and the medium portion gear 182 may rotate the plurality of chambers of the medium portion 110 by operating in cooperation with each other.

[0081] The turntable gear 181 may be engaged with the input portion 160 and the medium portion gear 182 , and may transmit rotational energy applied to the input portion 160 to the medium portion gear 182 .

[0082] The input portion 160 can be rotated by a user manipulating the input portion 160 using, for example, a rotational input. Rotational input is a user input for rotating the input portion 160 while maintaining contact with the input portion 160. Thus, rotational input can be applied from the moment the input portion 160 is rotated until the user releases contact. The input portion 160 can correspond to, for example, a turntable, but is not limited thereto. A portion of the input portion 160 can protrude from the exterior of the aerosol generating device 100. The input portion 160 can engage with the turntable gear 181, and the rotational force of the input portion 160 can be transmitted to the turntable gear 181.

[0083] The media section gear 182 can be arranged around the media section 110 so that the media section 110 rotates together with the media section gear 182. The media section gear 182 can rotate a single chamber or the plurality of chambers in the media section 110. The plurality of chambers can be physically separated from each other by a separator. Although the media section 110 is shown as including four chambers, the number of chambers is not limited thereto.

[0084] exist Figure 2 In the embodiment, the input section 160, the turntable gear 181, and the media section gear 182 have a sawtooth shape, but the shape is not limited to this. Furthermore, depending on the embodiment, the turntable gear 181, the input section 160, and the media section gear 182 may be arranged in various ways. Furthermore, the turntable gear 181, the input section 160, and the media section gear 182 may have different numbers of saw teeth, and the number of saw teeth may be determined according to a specific ratio. For example, the ratio of the number of saw teeth of the input section 160, the turntable gear 181, and the media section gear 182 may be 1:2:3, and the number of saw teeth of the input section 160, the turntable gear 181, and the media section gear 182 may be four, eight, and twelve, respectively. However, the number of saw teeth and the ratio of the number of saw teeth are not limited to this.

[0085] The rotation directions of the input portion 160, the turntable gear 181, and the medium portion gear 182 may be the same or different. For example, when the input portion 160 rotates clockwise, the turntable gear 181 may rotate counterclockwise, and the medium portion gear 182 may rotate clockwise. However, the embodiment is not limited thereto.

[0086] If desired, at least one of the input portion 160, the turntable gear 181, and the media portion gear 182 may be omitted. For example, the turntable gear 181 and the media portion gear 182 may be omitted, and the input portion 160 may be directly coupled to the media portion 110 and rotate the media portion 110. Alternatively, the turntable gear 181 may be omitted, the input portion 160 may rotate in response to a rotational input, and the media portion gear 182 directly coupled to the input portion 160 may rotate the media portion 110.

[0087] The input portion 160, the turntable gear 181, and the medium portion gear 182 may include various materials, and may include different materials, respectively.

[0088] Figure 3 is a block diagram of a hardware configuration of an aerosol generating device according to an embodiment.

[0089] Reference Figure 3 , the aerosol generating device 100 may include a chamber 111, a vaporizer 120, an input portion 160, an input circuit 170, and a processor 130. The input circuit 170 may include a rotating device 171 and a plurality of connecting devices 173-176. Figure 3 The chamber 111, input portion 160, and processor 130 shown in FIG. 1 may correspond to Figure 1 and Figure 2 The chamber, the input portion 160 and the processor 130 in FIG. Therefore, repeated description thereof is omitted.

[0090] Figure 3 Only some of the components of the aerosol generating device 100 that are particularly relevant to this embodiment are shown. Therefore, a person skilled in the art will understand that, in addition to including Figure 3 In addition to the components shown in FIG, the aerosol generating device 100 may further include other components.

[0091] The aerosol generating device 100 may include at least one chamber 111. The chamber 111 may store a flavoring material. When a plurality of chambers 111 are provided, the chambers may be connected to each other to form a component (e.g., the medium portion 110), while the chambers are separated by a separator (e.g., a partition wall).

[0092] The input portion 160 can rotate the chamber 111 by a user through rotation input. The input portion 160 can contact the medium portion 110 or directly contact the chamber 111 and rotate the chamber 111. Alternatively, the input portion 160 can indirectly rotate the chamber 111 through at least one intermediate component (e.g., the turntable gear 181 or the medium portion gear 182) disposed between the input portion 160 and the chamber 111.

[0093] The input circuit 170 may be electrically connected to the processor 130 and may transmit a specific signal to the processor 130 in response to the rotation of the input portion 160. The input circuit 170 may include a rotating device 171 that is coupled to the input portion 160 and rotates together with the input portion 160. The rotating device 171 may be physically or electrically connected to the input portion 160 and may rotate in accordance with the rotation of the input portion 160. The rotating device 171 may correspond to, for example, a device, an electronic component, a pin, etc. that is arranged to be rotatable on the surface of the input circuit 170. However, this is merely an example, and the type of the rotating device 171 is not limited thereto.

[0094] The input circuit 170 may include a plurality of connection devices 173 to 176. The connection devices 173 to 176 may be respectively connected to different parts of the processor 130. For example, different parts of the processor 130 respectively connected to the connection devices 173 to 176 may correspond to different circuits, different terminals, different ports (e.g., general purpose input / output ports), etc.

[0095] The connection devices 173 to 176 may generate specific signals and transmit the signals to the processor 130. When the rotating device 171 rotates and is thus positioned to correspond to one of the connection devices, the signal generated from the connection device may change. The connection device may transmit the changed signal to the processor 130.

[0096] The processor 130 may receive the changed signal and execute a function corresponding to the connection device that has generated the changed signal among the connection devices 173 to 176. In other words, the processor 130 may execute a function corresponding to the connection device that corresponds to the position of the rotation device 171 among the connection devices 173 to 176.

[0097] At least one function may correspond to each of the connection devices 173 to 176. Alternatively, when a plurality of chambers 111 are provided, the connection devices 173 to 176 may respectively correspond to the plurality of chambers 111. In this case, the number of the connection devices 173 to 176 may correspond to the number of the chambers 111.

[0098] The input portion 160 can also receive a push input by the user pushing the input portion 160 in a direction from the outside toward the inside of the aerosol generating device 100, like pushing a button. In this case, the input portion 160 can be configured to receive both a rotation input and a push input. The aerosol generating device 100 may include a push-pull switch, a tactile switch, or the like connected to the input portion 160 so as to be responsive to the push input. The tactile switch may refer to a switch that can give the user a "click" contact feeling, and the tactile switch may include, for example, a switch that moves while being elastically supported by an elastic element, or a dorm-shaped switch that can be elastically deformed (transformed).

[0099] The processor 130 may execute various functions in response to a push input. For example, the processor 130 may execute different functions based on the strength of the push input, the number of times the push input is received, or a combination thereof. Alternatively, the processor 130 may execute a function corresponding to the total number of times the push input is received during a preset time period (e.g., three seconds) from the time the push input is first received.

[0100] Processor 130 may initiate heating or preheating of vaporizer 120 in response to a push input. Alternatively, processor 130 may control vaporizer 120 to be heated according to a temperature profile corresponding to the strength of the push input, the number of push inputs received, or a combination thereof. For example, processor 130 may apply a high-temperature temperature profile when the strength of the push input is relatively high, and may apply a normal-temperature temperature profile when the strength of the push input is relatively low. Alternatively, processor 130 may apply a high-temperature temperature profile when two push inputs are received during a preset period, and may apply a normal-temperature temperature profile when a single push input is received during the preset period.

[0101] The processor 130 may turn the aerosol generating device on and off in response to the push input. For example, when the push input continues for a specific period of time or longer, the processor 130 may turn the aerosol generating device on or off.

[0102] In an embodiment, the aerosol generating device 100 may include a force sensor connected to the input portion 160 to detect the strength of the push input. The force sensor may sense, for example, a change in inductance of an internal space of the force sensor to detect pressure applied to the input portion 160.

[0103] Figure 4 is a diagram for describing a combination of an input portion and a rotating device according to an embodiment.

[0104] Reference Figure 4, the rotating device 171 may be combined with the input portion 160. As the input portion 160 rotates, the rotating device 171 may rotate while the input circuit 170 is fixed.

[0105] The input portion 160 and the rotating device 171 can be physically coupled to each other to rotate together. Figure 4 In an embodiment, the rotating device 171 may be protrudingly formed on the substrate of the input circuit 170 and may be inserted into the hole of the input portion 160. Furthermore, a protrusion may be formed on the rotating device 171, and a recess corresponding to the protrusion may be formed in the hole of the input portion 160 so that the rotating device 171 can be inserted. Thus, the rotating device 171 can rotate together with the input portion 160.

[0106] However, the combination of the rotating device 171 and the input part 160 is not limited to the above example and can be implemented in various ways. For example, the rotating device 171 can pass through the input part 160 through a hole in the input part 160. Alternatively, the rotating device 171 can be formed concavely on the substrate of the input circuit 170, and a convex portion corresponding to the rotating device 171 can be formed on the input part 160 to fit into the rotating device 171, thereby combining the rotating device 171 with the input part 160.

[0107] In an embodiment, the input portion 160 and the rotating device 171 may not be in direct contact, but may be connected via another component located between the input portion 160 and the rotating device 171. The rotating device 171 may rotate together with the input portion 160 via an intermediate component.

[0108] In another embodiment, the input portion 160 and the rotating device 171 may be electrically connected to each other. An electrical signal may be generated when the input portion 160 rotates, and the electrical signal may be provided to the input circuit 170. The input circuit 170 may rotate the rotating device 171 based on the electrical signal.

[0109] The ratio between the rotation angle of the input portion 160 and the rotation angle of the rotating device 171 can be set differently. For example, the rotation angle of the input portion 160 can be set to be equal to the rotation angle of the rotating device 171, and the input portion 160 and the rotating device 171 can rotate at a ratio of 1:1. However, this is merely an example and is not limited thereto.

[0110] Figure 5a is a transverse cross-sectional view of a single chamber according to an embodiment.

[0111] Reference Figure 5a, the aerosol generating device 100 may include a chamber 111 , and the chamber 111 may store a flavor material 112 .

[0112] exist Figure 5a In the embodiment, the chamber 111 surrounds the entire area of ​​the medium portion 110 in the circumferential direction, but the structure of the chamber 111 is not limited thereto. For example, the chamber 111 may surround only a partial area of ​​the medium portion 110 in the circumferential direction.

[0113] As the chamber 111 is rotated by the input portion 160, the relative rotational position of the chamber 111 relative to the vaporizer 120 may change. The area of ​​the chamber 111 corresponding to the exhaust port 121 of the vaporizer 120 may change according to the rotational position of the chamber 111. The aerosol may pass through the area of ​​the chamber 111 corresponding to the exhaust port 121.

[0114] Although the chamber 111 is not visually divided, the processor 130 may divide the chamber 111 into a plurality of regions in the circumferential direction of the medium portion 110, taking into account the area of ​​the fragrance material 112 corresponding to the size of the discharge port 121. For example, among the plurality of regions of the chamber 111, when the fragrance material 112 in the current region for aerosol to pass through is exhausted, the processor 130 may align the next region of the plurality of regions with the discharge port 121 by rotating the chamber 111.

[0115] Figure 5b is a transverse cross-sectional view of a plurality of chambers according to an embodiment.

[0116] Reference Figure 5b The aerosol generating device 100 may include a plurality of chambers 111 sequentially arranged along the rotation direction, and the chambers 111 may store the flavor material 112. The chambers 111 may be separated from each other by a separator 114 of the medium portion 110.

[0117] As the chamber 111 is rotated by the input portion 160, the relative position of the chamber 111 with respect to the vaporizer 120 may change. Figure 5b As shown in FIG, the chambers 111 are aligned so that the position of one of the chambers 111 corresponds to the position of the exhaust port 121. The chamber 113 corresponding to the exhaust port 121 of the vaporizer 120 may vary depending on the position of the chamber 111.

[0118] As input portion 160 rotates, not only chamber 111 but also rotating device 171 may rotate. As rotating device 171 rotates, the connection device corresponding to the position of rotating device 171 may change. When the position of rotating device 171 corresponds to the connection device, chamber 113 corresponding to discharge port 121 may be set as the chamber corresponding to the connection device. For example, if first chamber 113 corresponds to discharge port 121 when the position of rotating device 171 corresponds to the first connection device, first chamber 113 may be set as the chamber corresponding to the first connection device. Therefore, processor 130 may determine chamber 113 as the active chamber. In this case, chamber 113 may be in fluid communication with vaporizer 120 and aerosol may pass through chamber 113.

[0119] Figure 6 is a diagram showing connections between an input circuit and a processor according to an embodiment.

[0120] Reference Figure 6 , the plurality of connecting devices 173 to 176 are respectively connected to different parts A, B, C and D of the processor 130 , and the reference point 172 of the rotating device 171 can be positioned to correspond to the connecting device 174 .

[0121] Each of the connection devices 173 to 176 may correspond to, for example, an electronic device, a common (C) pin, a port, or a switch arranged on the substrate of the input circuit 170 , but is not limited thereto.

[0122] In an embodiment, the processor 130 may control the battery 140 so that signals having different voltages are applied to the connection devices 173 to 176 and the rotating device 171. For example, when the battery 140 applies a signal having a first voltage to the connection devices 173 to 176 and a signal having a second voltage to the rotating device 171, the signal having the first voltage may be generated in the connection devices 173 to 176, and the signal having the second voltage may be generated in the rotating device 171.

[0123] In another embodiment, a basic circuit configured to apply a signal having a first voltage may be connected to the connection devices 173 to 176, and when the rotation device 171 rotates and is thus positioned to correspond to the connection device 174 among the connection devices 173 to 176 by being electrically connected to the connection device 174, the voltage of the signal applied to the connection device 174 may be changed to a second voltage. To this end, the rotation device 171 may include, for example, a resistor, a capacitor, an amplifier, and a semiconductor such as a complementary metal oxide semiconductor (CMOS) or a transistor-transistor logic (TTL).

[0124] The processor 130 may detect the voltage applied to the connection devices 173 to 176 by receiving a signal applied to the connection devices 173 to 176 from the connection device 173 .

[0125] When rotating device 171 is positioned to correspond to one connecting device 174, rotating device 171 and connecting device 174 can be connected to each other. Instead of the previously applied signal, the signal applied to rotating device 171 can be applied to connecting device 174 via rotating device 171. That is, when rotating device 171 rotates to align with connecting device 174, the signal generated in connecting device 174 can change. Processor 130 can receive the signals generated by connecting devices 173 to 176 and, upon receiving the changed signal, can determine that connecting device 174 has generated the changed signal. That is, processor 130 can receive the changed signal and determine that connecting device 174, which has generated the changed signal, corresponds to the position of rotating device 171.

[0126] When a signal having a first voltage is applied to connection devices 173 to 176 and rotation device 171 is positioned corresponding to connection device 174, the signal applied to connection device 174 may change from the signal having the first voltage to a signal having a second voltage. For example, when the first voltage is a reference voltage (e.g., 3V) and the second voltage is a ground voltage, the signal generated in connection device 174 may change from a high signal having the reference voltage to a low signal having the ground voltage. Processor 130 may determine that connection device 174 among connection devices 173 to 176 in which a high signal is detected and then changes to a low signal is connection device 174 corresponding to the position of rotation device 171. Alternatively, when the first voltage is a ground voltage and the second voltage is a reference voltage, processor 130 may determine that connection device 174 in which the signal changes from a low signal to a high signal is connection device 174 corresponding to the position of rotation device 171.

[0127] The processor 130 may execute a function corresponding to the connection device 174 among the connection devices 173 to 176, which corresponds to the position of the reference point 172 of the rotating device 171. The reference point 172, which is a virtual point on the rotating device 171, may be used to determine which connection device among the plurality of connection devices 173 to 176 corresponds to the rotating device 171. Figure 6 In the embodiment, the processor 130 may determine that when the rotation device 171 rotates according to the rotation input, the connection device 174 corresponds to the position of the reference point 172. The connection devices 173 to 176 may transmit different changes to the processor 130 according to the position of the reference point 172.

[0128] For example, when a direction from the rotation axis of the rotating device 171 toward the reference point 172 points to the position of the connecting device 174 , the reference point 172 may be positioned to correspond to the connecting device 174 .

[0129] When the reference point 172 of the rotating device 171 is positioned to correspond to the connecting device 174 among the plurality of connecting devices 173 to 176 , the processor 130 may perform a function corresponding to the connecting device 174 .

[0130] In an embodiment, the connection devices 173 to 176 may correspond to different chambers 111, respectively. The processor 130 may determine the chamber 113 corresponding to the connection device 174 among the plurality of chambers 111 as the chamber in use. The chamber in use may be in fluid communication with the vaporizer, and the aerosol generated from the vaporizer may pass through the chamber in use. In addition, the chamber in use may be aligned with the exhaust port 121 of the vaporizer 120.

[0131] In an embodiment, the connection devices 173 to 176 may each correspond to a different temperature profile. A temperature profile refers to the temperature change of the vaporizer 120 over time. For example, a temperature profile may refer to the temperature change of the vaporizer 120 during a smoking operation. The processor 130 may control the vaporizer 120 to be heated according to the temperature profile corresponding to the connection device 174.

[0132] In an embodiment, the aerosol generating device 100 may include a puff sensor configured to detect a user's puff. The puff sensor may detect changes in pressure or air velocity generated when the user puffs the aerosol. The puff sensor may include a pressure sensor, an air flow sensor, etc.

[0133] The processor 130 can count the number of puffs of the chamber 113 corresponding to the connection device 174 (i.e., the chamber in use) by using the puff sensor. For example, the processor 130 can determine that the chamber 113 corresponding to the connection device 174 is the chamber in use, and can count the number of puffs in the chamber 113 by using the puff sensor. When the counted number of puffs is equal to or greater than a threshold value, the processor 130 can limit the function corresponding to the connection device 174. For example, when the function is to heat the vaporizer 120, the processor 130 can limit the operation of the vaporizer 120 related to the chamber where the number of puffs is equal to or greater than the threshold value. Since the operation of the vaporizer 120 is limited, a burnt smell or the like is not generated in the aerosol, and user satisfaction can be improved.

[0134] When the counted number of puffs is equal to or greater than a threshold value, the aerosol generating device 100 may provide a notification to the user by using a light emitting portion, a display, a speaker, or the like.

[0135] In an embodiment, the aerosol generating device 100 may include a light emitting portion configured to emit light. The light emitting portion may emit light of various colors, or the light emitting portion may emit light at various periods, at various brightnesses, or during various time periods. For example, the light emitting portion may include a light emitting diode (LED). However, the light emitting portion is not limited thereto and may include various configurations of light emission.

[0136] The processor 130 can control the light emitting portion to emit light corresponding to the connection device 174. For example, the light emitting portion can emit a light pattern of a different color for each connection device 173 to 176, or can flash each time the connection device 174 corresponding to the position of the rotating device 171 changes. Alternatively, the light emitting portion can emit a light pattern of different brightness for each connection device 173 to 176, or emit light for different time periods. When the connection devices 173 to 176 correspond to different chambers 111, the user can check which chamber is in use based on the light emitted by the light emitting portion.

[0137] In an embodiment, the aerosol generating device 100 may include a vibrator for outputting tactile information. The vibrator may generate vibrations at various cycles, various intensities, or during various time periods. When the vibrator vibrates, the aerosol generating device 100 vibrates, and tactile information may be provided to the user.

[0138] The processor 130 may change the vibration pattern of the vibrator to correspond to the connection device 174. For example, the vibrator may vibrate for a preset period of time each time the connection device 174 corresponding to the position of the rotating device 171 changes. Alternatively, the vibrator may vibrate with different intensities or at different periods for each connection device 174. When the connection devices 174 correspond to different chambers 111, the user can identify the chamber in use based on the vibration of the vibrator.

[0139] In an embodiment, the aerosol generating device 100 may include a display configured to output visual information. The display may output visual information corresponding to the connection device 174. For example, the display may output visual information corresponding to the chamber in use. In this case, the user can identify the chamber in use by the visual information displayed on the display.

[0140] In an embodiment, the aerosol generating device 100 may include a memory configured to store information corresponding to each of the connection devices 173 to 176. For example, one memory may store information for each of the connection devices 173 to 176 in one of a plurality of areas, or a plurality of memories may each store information for each of the connection devices 173 to 176.

[0141] The processor 130 may execute a function corresponding to the connection device 174 based on the information stored in the memory. When the connection device 174 corresponds to different chambers 111, the memory may separately store the accumulated number of puffs associated with each of the chambers 111, and the processor 130 may control the operation of the vaporizer 120 based on the accumulated number of puffs associated with the chamber in use.

[0143] Reference Figure 7 , an example of a method of operating the aerosol generating device 100 includes Figure 3 Therefore, even if omitted hereinafter, the operations of the aerosol generating device 100 will be described in detail. Figure 3 The foregoing description of the aerosol generating device 100 shown in FIG may also be applied to Figure 7 The method of operating the aerosol generating device 100 shown in FIG.

[0144] In operation S710, the input portion 160 may be rotated by a user.

[0145] In another embodiment, the input portion 160 may be pushed by the user, and in this case, the input portion 160 may recognize the push input as well as the rotation input.

[0146] In operation S720 , the chamber 111 and the rotating device 171 may rotate according to the rotation of the input portion 160 .

[0147] The input portion 160 can rotate the chamber 111 by a user-induced rotational movement of the input portion 160. The chamber 111 can be arranged to rotate relative to the vaporizer 120 and can store the flavor material 112, so that the aerosol passes through the flavor material 112. When a plurality of chambers 111 are provided, the plurality of chambers 111 can be positioned sequentially along the rotational direction of the medium portion 110 including the chambers 111. The vaporizer 120 can be arranged in fluid communication with one of the plurality of chambers 111 and can generate an aerosol by heating the aerosol-generating substance.

[0148] The rotating device 171 may be coupled to the input portion 160 such that the rotating device 171 rotates together with the input portion 160 .

[0149] In operation S730 , a signal generated in the connection device 174 corresponding to the position of the rotation device 171 among the plurality of connection devices 173 to 176 may be changed.

[0150] Each of the connection devices 173 to 176 may generate a signal. The signal generated by the connection device 174 corresponding to the current position of the rotation device 171 among the connection devices 173 to 176 may be changed. The connection device 174 may send the changed signal to the processor 130.

[0151] In operation S740, the processor 130 may receive the changed signal.

[0152] The processor 130 may determine that the connection device 174 corresponds to the position of the rotation device 171 based on the changed signal.

[0153] In operation S750 , the processor 130 may perform a function corresponding to the connection device 174 that has generated the changed signal among the plurality of connection devices 173 to 176 .

[0154] The processor 130 may determine the chamber 113 corresponding to the connection device 174 corresponding to the position of the rotating device 171 as the chamber in use from the plurality of chambers 111.

When the counted number of puffs is equal to or greater than a threshold value, the aerosol generating device 100 may limit the operation of the vaporizer 120 related to the chamber 113 (i.e., the chamber in use).

[0157] The processor 130 may control the light emitting portion so that light corresponding to the connection device 174 corresponding to the position of the rotating device 171 is emitted.
