DETAILED DESCRIPTION OF THE INVENTION

[0024] The terms used in the embodiments have been selected as widely used terms as possible while taking into consideration the functions in the embodiments, but these may differ depending on the intentions of those skilled in the art, legal precedents, the emergence of new technologies, etc. In addition, in certain cases, the applicant may have arbitrarily selected terms, and in such cases, the meanings thereof will be described in detail in the relevant description of the invention. Therefore, the terms used in the present invention should be defined not simply as names of terms, but based on the meanings of the terms and the overall content of the present invention.

[0025] Throughout the specification, when any part "includes" any component, this does not exclude other components, but means that it further includes other components, unless otherwise specified. Furthermore, terms such as "unit" and "module" used in the specification refer to a unit that processes at least one function or operation, and this may be embodied as hardware or software, or a combination of hardware and software.

[0026] As used herein, when phrases such as "at least one" precede an array of elements, they modify the entire array, not each individual element of the array. For example, the phrase "at least one of a, b, and c" should be interpreted as including a, b, and c, or a and b, a and c, b and c, or a, b, and c.

[0027] In one embodiment, the aerosol generating device is a device that generates aerosol by electrically heating cigarettes contained within an interior space.

[0028] The aerosol generating device includes a heater. In one embodiment, the heater may be an electrically resistive heater. For example, the heater may include an electrically conductive track, and when an electric current is passed through the electrically conductive track, the heater heats up.

[0029] The heater may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and depending on the shape of the heating element, the interior or exterior of the cigarette will be heated.

[0030] Cigarettes include tobacco rods and filter rods. The tobacco rods may be manufactured in sheets, strands, or shredded tobacco sheets. The tobacco rods may also be surrounded by a heat-conducting material. For example, the heat-conducting material may be a metal foil such as aluminum foil, but is not limited to this.

[0031] The filter rod may be a cellulose acetate filter. The filter rod may be composed of at least one or more segments. For example, the filter rod may include a first segment that cools the aerosol and a second segment that filters a predetermined component contained in the aerosol.

[0032] In other embodiments, the aerosol generating device may be a device that generates the aerosol using a cartridge that holds the aerosol generating substance.

[0033] The aerosol generating device includes a cartridge that holds an aerosol-generating material and a body that supports the cartridge. The cartridge is detachably connected to the body, but is not limited thereto. The cartridge may be integrally formed or assembled with the body, or may be fixed so that it cannot be detached by a user. The cartridge may be attached to the body with the aerosol-generating material contained therein. However, without being limited thereto, the aerosol-generating material may be injected into the cartridge while the cartridge is connected to the body.

[0034] The cartridge holds an aerosol-forming material in any one of a variety of states, such as a liquid state, a solid state, a gas state, or a gel state. The aerosol-forming material includes a liquid-phase composition. For example, the liquid-phase composition may be a liquid containing a tobacco-containing substance including a volatile tobacco aroma component, or a liquid containing a non-tobacco substance.

[0035] The cartridge is activated by an electrical signal or a wireless signal transmitted from the main body, and functions to convert the phase of the aerosol-generating material inside the cartridge into a gas phase to generate an aerosol. The aerosol refers to a gas mixture of vaporized particles generated from the aerosol-generating material and air.

[0036] In a further embodiment, the aerosol generating device heats the liquid phase composition to generate an aerosol, which is then transmitted through the cigarette to the user, i.e., the aerosol generated from the liquid phase composition travels along an airflow passage of the aerosol generating device, which can be configured to transmit the aerosol through the cigarette to the user.

[0037] In a further embodiment, the aerosol generating device may be a device that generates an aerosol from an aerosol-generating substance using ultrasonic vibration, where the ultrasonic vibration method refers to a method of generating an aerosol by aerosolizing the aerosol-generating substance using ultrasonic vibrations generated by a vibrator.

[0038] The aerosol generating device may include a vibrator that generates short-period vibrations to atomize the aerosol-generating substance. The vibrations generated by the vibrator may be ultrasonic vibrations, and the frequency band of the ultrasonic vibrations may be, but is not limited to, about 100 kHz to about 3.5 MHz.

[0039] The aerosol generating device may further include a wick for absorbing the aerosol-forming substance. For example, the wick may be positioned to surround or contact at least a region of the transducer.

[0040] When a voltage (e.g., an AC voltage) is applied to the vibrator, heat and / or ultrasonic vibrations are generated from the vibrator, and the heat and / or ultrasonic vibrations generated from the vibrator can be transferred to the aerosol-forming substance absorbed in the wick. The aerosol-forming substance absorbed in the wick is converted into a gas phase by the heat and / or ultrasonic vibrations transferred from the vibrator, resulting in the generation of an aerosol.

[0041] For example, the viscosity of the aerosol-generating material absorbed into the core may be reduced by heat generated from the vibrator, and the reduced viscosity aerosol-generating material may be broken down into fine particles by ultrasonic vibrations generated from the vibrator, thereby generating an aerosol, but this is not limited to this.

[0042] In a further embodiment, the aerosol generating device may be a device that generates an aerosol by heating an aerosol product contained in the aerosol generating device by induction heating.

[0043] The aerosol generating device includes a susceptor and a coil. In one embodiment, the coil applies a magnetic field to the susceptor. When power is supplied from the aerosol generating device to the coil, a magnetic field is formed inside the coil. In one embodiment, the susceptor may be a magnetic material that generates heat when exposed to an external magnetic field. When the susceptor is positioned inside the coil and a magnetic field is applied, the aerosol product is heated by the generated heat. Alternatively, the susceptor may be disposed inside the aerosol product.

[0044] In a further embodiment, the aerosol generating device may further comprise a cradle.

[0045] The aerosol generating device may be combined with a separate cradle to form a system. For example, the cradle may charge the battery of the aerosol generating device, or the heater may heat the aerosol generating device while the cradle and the aerosol generating device are combined.

[0046] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present disclosure. The present disclosure may be implemented in a form that can be realized in the aerosol generating device of the embodiment described above, or may be embodied in various different forms, but is not limited to the embodiments described herein.

[0047] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

The output unit 130 includes, but is not limited to, at least one of a display unit 132, a haptic unit 134, and an audio output unit 136. When the display unit 132 and the touchpad have a layered structure to form a touch screen, the display unit 132 may be used as an input device in addition to an output device.

[0056] The display unit 132 can visually provide a user with information about the aerosol generating device 100. For example, the information about the aerosol generating device 100 can mean various information such as the charging / discharging status of the battery 140 of the aerosol generating device 100, the preheating status of the heater 150, the insertion / removal status of an aerosol product, or a status in which use of the aerosol generating device 100 is restricted (e.g., detection of an abnormal item), and the display unit 132 can output the information to the outside. The display unit 132 may be, for example, a liquid crystal display panel (LCD), an organic light emitting display panel (OLED), or the like. Furthermore, the display unit 132 may be an LED light emitting element.

[0057] The haptic unit 134 can convert an electrical signal into a mechanical or electrical stimulus to tactilely provide the user with information about the aerosol generating device 100. For example, the haptic unit 134 includes a motor, a piezoelectric element, or an electrical stimulation device.

[0058] The acoustic output unit 136 audibly provides the user with information relating to the aerosol generating device 100. For example, the acoustic output unit 136 can convert an electrical signal into an acoustic signal and output it to the outside.

[0059] The battery 140 supplies power used to operate the aerosol generating device 100. The battery 140 supplies power to the heater 150 so that it can heat. The battery 140 can also supply power necessary for the operation of other components provided within the aerosol generating device 100 (e.g., the detection unit 120, the output unit 130, the user input unit 160, the memory 170, and the communication unit 180). The battery 140 may be a rechargeable battery or a disposable battery. For example, the battery 140 may be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0060] The heater 150 can heat the aerosol-generating material by receiving power from the battery 140. Although not shown in Fig. 1, the aerosol-generating device 100 may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power of the battery 140 and supplies it to the heater 150. Furthermore, when the aerosol-generating device 100 generates aerosol by an induction heating method, the aerosol-generating device 100 may further include a DC / AC converter that converts the DC power of the battery 140 into AC power.

[0061] The control unit 110, the detection unit 120, the output unit 130, the user input unit 160, the memory 170, and the communication unit 180 can function by receiving power from the battery 140. Although not shown in FIG. 1 , the device may further include a power conversion circuit, such as an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the battery 140 and supplies it to each component.

[0062] In one embodiment, heater 150 may be formed from any suitable electrically resistive material, including, but not limited to, metals or metal alloys such as titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nichrome, etc. Additionally, heater 150 may be implemented as, but not limited to, a metal hot wire, a metal hot plate having an electrically conductive track disposed thereon, a ceramic heating element, etc.

[0063] In another embodiment, heater 150 may be an induction heater, for example, heater 150 may include a susceptor that generates heat via a magnetic field applied by a coil to heat the aerosol-generating material.

[0064] The user input unit 160 can receive information input by a user and output information to a user. For example, the user input unit 160 can be, but is not limited to, a keypad, a dome switch, a touchpad (e.g., a contact-type capacitance type, a pressure-type resistive film type, an infrared sensing type, a surface ultrasonic conduction type, an integral tension measurement type, a piezoelectric effect type, etc.), a jog wheel, a jog switch, etc. Although not shown in FIG. 1 , the aerosol generating device 100 can further include a connection interface such as a USB (universal serial bus) interface, and can connect to other external devices via the connection interface such as the USB interface to send and receive information or charge the battery 140.

[0065] The memory 170 is hardware that stores various data processed within the aerosol generating device 100, and can store data that has been processed by the control unit 110 and data to be processed by the control unit 110. The memory 170 includes at least one type of storage medium selected from the group consisting of flash memory, hard disk, micro multimedia card, card-type memory (e.g., SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk. The memory 170 may store the operating time of the aerosol generating device 100, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data regarding the user's smoking pattern.

[0066] The communication unit 180 includes at least one component for communicating with other electronic devices. For example, the communication unit 180 may include a short-range communication unit 182 and a wireless communication unit 184.

[0067] The short-range wireless communication unit 182 includes, but is not limited to, a Bluetooth (registered trademark) communication unit, a BLE (Bluetooth (registered trademark) Low Energy) communication unit, a Near Field Communication unit, a WLAN (Wi-Fi) communication unit, a Zigbee (registered trademark) communication unit, an IrDA (infrared Data Association) communication unit, a WFD (Wi-Fi Direct) communication unit, a UWB (ultra wideband) communication unit, an Ant+ communication unit, etc.

[0068] The wireless communication unit 184 may include, but is not limited to, a cellular network communication unit, an Internet communication unit, a computer network (e.g., LAN or WAN) communication unit, etc. The wireless communication unit 184 may use subscriber information (e.g., International Mobile Subscriber Identity (IMSI)) to identify and authenticate the aerosol generating device 100 within the communication network.

[0069] The control unit 110 can control the overall operation of the aerosol generating device 100. In one embodiment, the control unit 110 includes at least one processor. The processor may be realized as an array of multiple logic gates, or may be realized as a combination of a general-purpose microprocessor and a memory storing a program that can be executed by the microprocessor. Furthermore, it will be understood by those skilled in the art to which this embodiment pertains that the processor may be realized in other forms of hardware.

[0070] The control unit 110 controls the temperature of the heater 150 by controlling the supply of power from the battery 140 to the heater 150. For example, the control unit 110 may control the power supply by controlling the switching of a switching element between the battery 140 and the heater 150. As another example, a heating direct circuit may control the power supply to the heater 150 in response to a control command from the control unit 110.

[0071] The control unit 110 analyzes the results detected by the detection unit 120 and controls the processes to be executed thereafter. For example, the control unit 110 can control the amount of power supplied to the heater 150 so that the operation of the heater 150 starts or ends based on the results detected by the detection unit 120. As another example, the control unit 110 can control the amount of power supplied to the heater 150 and the time for which the power is supplied based on the results detected by the detection unit 120 so that the heater 150 can heat up to a predetermined temperature or maintain an appropriate temperature.

[0072] The control unit 110 controls the output unit 130 based on the result detected by the detection unit 120. For example, when the number of puffs counted via the puff sensor 126 reaches a preset number, the control unit 110 can notify the user via at least one of the display unit 132, the haptic unit 134, and the audio output unit 136 that the aerosol generating device 100 will immediately shut down.

[0073] In one embodiment, the control unit 110 can control the time and / or amount of power supplied to the heater 150 depending on the state of the aerosol product detected by the detection unit 120. For example, when the aerosol product (e.g., the aerosol product 201) is in an over-humid state, the control unit 110 can control the time of power supply to the induction coil to increase the pre-heating time compared to when the aerosol product (e.g., the aerosol product 201) is in a normal state.

[0074] 2 to 7, the aerosol generation system 20 includes an aerosol generation device 200 and an aerosol production product 201. The aerosol generation device 200 accommodates the aerosol production product 201 in an internal space (for example, the product insertion section 2121 in FIG. 2), and can generate an aerosol by electrically heating the aerosol production product 201.

[0075] Referring to FIG. 2, the aerosol generating device 200 includes a housing 210 , a cartridge 220 , and an actuator 230 .

[0076] In one embodiment, the housing 210 includes a first housing part 211 and a second housing part 212 that can be coupled to the first housing part 211. For example, the first housing part 211 and the second housing part 212 are rotatably connected about a hinge 213. The housing 210 can be switched between an open mode and a closed mode. In the open mode, the first housing part 211 and the second housing part 212 are separated about the hinge 213, and in the closed mode, the first housing part 211 and the second housing part 212 are coupled to each other so that they are in close contact with each other. In the open mode, one surface of the second housing part 212 that faces the first housing part 211 is exposed, and here, the cartridge accommodating portion 2111 is also exposed to the outside of the second housing part 212, allowing the cartridge 220 to be inserted into the cartridge accommodating portion 2111.

[0077] In one embodiment, a cartridge receiving portion 2111 into which the cartridge 220 is inserted may be provided on one side of the first housing part 211. The cartridge receiving portion 2111 may be realized as a space recessed from one side of the first housing part 211 to the interior.

[0078] In one embodiment, the actuator 230 may be disposed adjacent to the cartridge receiving portion 2111 inside the first housing part 211. The actuator 230 may activate the cartridge 220 received in the cartridge receiving portion 2111, which will be described in detail below. A power supply unit (e.g., a battery) (not shown) and a control unit (not shown) may be disposed adjacent to the actuator 230 to contribute to the activation of the actuator 230.

[0079] 3, a cartridge 220 is inserted into a cartridge receiving portion 2111 of an aerosol generating device 200 according to one embodiment, and the outer shape of the cartridge 220 is formed to correspond to the inner shape of the cartridge receiving portion 2111. For example, a liquid flavorant is received in the cartridge 200, and the liquid flavorant is ejected out of the cartridge 200 through liquid injection pins 2211, 2221, and 2231 protruding from the cartridge 200.

[0080] The protruding lengths of the liquid injection pins 2211 , 2221 , 2231 are set so that at least a portion of the liquid injection pins 2211 , 2221 , 2231 protrude outside the first housing part 211 when the cartridge 220 is inserted into the cartridge accommodating portion 2111 .

[0081] 4A to 4C, the cartridge 220 of the aerosol generating device 200 according to one embodiment includes a plurality of cartridge parts 221, 222, and 223, each containing a different liquid-phase flavorant. For example, the cartridge 220 includes a first cartridge part 221, a second cartridge part 222, and a third cartridge part 223. The number of cartridge parts 221, 222, and 223 is not necessarily limited thereto, and for example, the cartridge 220 may include only the first cartridge part 221 and the second cartridge part 222.

[0082] In one embodiment, the first cartridge part 221 contains a first liquid-phase flavor, the second cartridge part 222 contains a second liquid-phase flavor, and the third cartridge part 223 contains a third liquid-phase flavor. For example, the first liquid-phase flavor, the second liquid-phase flavor, and the third liquid-phase flavor may be different concentrates and may include menthol, peppermint, spearmint oil, various fruit flavor components, etc., and may contain components that can provide the user with various flavors or tastes. Furthermore, the first cartridge part 221, the second cartridge part 222, and the third cartridge part 223 may contain a vitamin mixture, such as, but not limited to, vitamin A, vitamin B, vitamin C, vitamin E, or a mixture of at least one of them.

[0083] In one embodiment, the cartridge accommodating portion 2111 may include a plurality of divided compartments, each of which may accommodate a corresponding cartridge part (e.g., a first cartridge part 221, a second cartridge part 222, and a third cartridge part 223). For example, as shown in FIG. 4B, the cartridge accommodating portion 2111 may include three divided compartments, each of which is separated by a partition wall. By having the cartridge accommodating portion 2111 divided compartments, when the liquid fragrance accommodated in any one of the cartridge parts 221, 222, and 223 according to one embodiment is consumed, the corresponding cartridge part can be easily replaced. The cartridge accommodating portion 2111 has a circular cross section when viewed from the second housing part 212, and the plurality of compartments of the cartridge accommodating portion 2111 may be divided at equal intervals. Here, the first cartridge part 221, the second cartridge part 222, and the third cartridge part 223 may also have the shape of a cut cylinder divided at equal intervals.

[0084] In one embodiment, a first liquid-phase injection pin 2211 is provided at one end of the first cartridge part 221, a second liquid-phase injection pin 2221 is provided at one end of the second cartridge part 222, and a third liquid-phase injection pin 2231 is provided at one end of the third cartridge part 223. The first liquid-phase injection pin 2211, the second liquid-phase injection pin 2221, and the third liquid-phase injection pin 2231 are arranged near the center point where the cartridge parts 221, 222, and 223 meet, and the diameter D of the cartridge accommodating section 2111 is formed larger than the diameter D of the article insertion section, so that the front end (upstream side) of the aerosol product 201 is guided to come into contact with the first liquid-phase injection pin 2211, the second liquid-phase injection pin 2221, and the third liquid-phase injection pin 2231.

[0085] In one embodiment, the actuator 230 can individually activate the first cartridge part 221, the second cartridge part 222, and the third cartridge part 223. For example, the actuator 230 causes the first liquid-phase flavor contained in the first cartridge part 221 to be ejected in a set amount through the first liquid-phase injection pin 2211, and causes the second liquid-phase flavor contained in the second cartridge part 222 to be ejected in a set amount through the second liquid-phase injection pin 2221, thereby supplying a preset combination of the first liquid-phase flavor and the second liquid-phase flavor to the side of the item insertion portion 2121. As a result, a combination of the first liquid-phase flavor and the second liquid-phase flavor can be supplied to the aerosol product 201. This is merely an example and is not necessarily limited to this. For example, the actuator 230 may activate the first cartridge part 221 so that only the first liquid phase fragrance is supplied alone to the aerosol product 201, or may activate the first cartridge part 221, the second cartridge part 222, and the third cartridge part 223 individually so that a combination of the first to third liquid phase fragrances is supplied to the aerosol product 201.

[0086] In one embodiment, one surface of either the first housing part 211 or the second housing part 212 includes a protrusion 2122 that protrudes toward the other of the first housing part 211 or the second housing part 212. For example, referring to FIG. 4B , the protrusion 2122 is formed on one surface of the first housing part 211 facing the second housing part 212, or vice versa. A plurality of protrusions 2122 are provided, and each of the protrusions 2122 is made of a hard material to prevent surface contact between the first housing part 211 and the second housing part 212. The protrusions 2122 form a separation space between the first housing part 211 and the second housing part 212, and the separation space is fluidly communicated with the item insertion part 2121, so that an airflow path can be formed from the outside of the aerosol generation device 200 according to one embodiment to the item insertion part 2121.

[0087] 4C , the aerosol generating device 200 according to one embodiment further includes a cartridge holding portion 2124. The cartridge holding portion 2124 may be provided on one side of the second housing part 212 facing the first housing part 211, and more specifically, on the end of the article insertion portion 2121 facing the first housing part 211. The cartridge holding portion 2124 may contact at least a portion of the cartridge 220 to hold the cartridge 220 in its original position within the cartridge accommodating portion 2111.

[0088] For example, the cartridge holding portion 2124 is formed so as to overlap with the outside of the upper portion of the first cartridge part 221 (for example, the surface on which the first liquid-phase injection pins 2211 are arranged) but not overlap with the inside surface on which the first liquid-phase injection pins 2211 are arranged. Similarly, the cartridge holding portion 2124 is formed so as to overlap with the outside of the upper portion of the second cartridge part 222 (for example, the surface on which the second liquid-phase injection pins 2221 are arranged) but not overlap with the inside surface on which the second liquid-phase injection pins 2221 are arranged, and is formed so as to overlap with the outside of the upper portion of the third cartridge part 223 (for example, the surface on which the third liquid-phase injection pins 2231 are arranged) but not overlap with the inside surface on which the third liquid-phase injection pins 2231 are arranged. Here, the diameter W of the non-overlapping portion formed on the inside of the cartridge holding portion 2124 is formed smaller than the diameter D of the cartridge accommodating portion 2111. In addition, the cartridge holding portion 2124 includes a plurality of bars that cover the boundary areas of the cartridge parts 221, 222, and 223. As a result, when the first housing part 211 and the second housing part 212 are coupled, the cartridge holding portion 2124 holds the cartridge parts 221, 222, and 223 in their original positions while pushing them into the cartridge accommodating portion 2111, and the first liquid injection pin 2211, the second liquid injection pin 2221, and the third liquid injection pin 2231 protrude to extend beyond the cartridge holding portion 2124 into the article insertion portion 2121.

[0089] 5 to 7, an aerosol generation system 20 according to one embodiment includes an aerosol generation device 200 and an aerosol product 201, and Fig. 5 shows the aerosol product 201 inserted into the aerosol generation device 200 according to one embodiment. Fig. 6 shows a portion of a cartridge 220 and an actuator 230 according to one embodiment, and Fig. 7 shows the aerosol product 201 according to one embodiment.

[0090] 5, in a closed mode of the aerosol generating device 200 according to one embodiment, the actuator 230, the cartridge 220, and the article insertion portion 2121 are aligned in a row. Therefore, the aerosol product 201 inserted into the article insertion portion 2121 is also aligned in a row with the cartridge 220 and the actuator 230, and the first liquid injection pin 2211, the second liquid injection pin 2221, or the third liquid injection pin 2231 is inserted into the front end of the aerosol product 201, so that each of the first to third liquid flavorings or a combination thereof can be supplied to the aerosol product 201.

[0091] In one embodiment, the article insert 2121 is formed through the second housing part 212, and in the closed mode, the centerline of the article insert 2121 that passes through the first housing part 212 can pass through the cartridge accommodating portion 2111 and the actuator 230.

[0092] In one embodiment, the diameter of the cartridge accommodating portion 2111 (e.g., cartridge accommodating portion diameter D in FIG. 4B) may be larger than the diameter of the article insertion portion (e.g., article insertion portion diameter D in FIG. 4B). Therefore, in the closed mode in which the cartridge 220 is inserted into the cartridge accommodating portion 2111 and the first housing part 211 and the second housing part 212 are coupled, the cartridge 220 can be efficiently prevented from being removed via the article insertion portion 2121.

[0093] In one embodiment, as shown in FIG. 6, a first liquid injection pin 2211 is provided at one end of the first cartridge part 221, and a first cartridge head 2212 is provided at the other end. The first cartridge head 2212 is movable within the first cartridge part 221, so that the first liquid flavoring contained inside the first cartridge part 221 can be ejected to the outside of the first liquid injection pin 2211. For example, the interior of the first cartridge part 221 has a horizontal cross section of a certain shape in the longitudinal direction (e.g., a triangle in FIG. 6), and the first cartridge head 2212 has a shape corresponding to the horizontal cross section of the first cartridge part 221 so as to seal the interior of the first cartridge part 221. Here, the longitudinal direction is perpendicular to the cutting plane for the horizontal cross section. Similarly, the second cartridge part 222 side and the third cartridge part 223 side of the cartridge 230 are also composed of elements that are the same as or similar to the first cartridge part 221 side.

[0094] In one embodiment, the actuator 230 may include a first push bar 231 that can strike or push the first cartridge head 2212 in the first cartridge part 221, and a driving element (not shown) that transmits forward and backward driving force to the first push bar 231. For example, the first push bar 231 and the driving element may be connected by a crankshaft or a rack and pinion gear, so that the rotational motion of the driving element can be converted into linear motion and transmitted to the first push bar 231.

[0095] Similarly, the actuator 230 includes a second push bar (not shown) that can strike or push the second cartridge head (not shown) of the second cartridge part 222, or a third push bar 233 (see Figure 5) that can strike or push the third cartridge head (not shown) of the third cartridge part 223.

[0096] For example, the first push bar 231 pushes the first cartridge head 2212 toward the first liquid injection pin 2211, and the first liquid flavoring is supplied to the front end of the aerosol product 201 according to an embodiment of the present invention through the first liquid injection pin 2211. Here, a control unit (not shown) can issue a command to drive the first push bar 231 forward by a set distance, thereby precisely discharging the first liquid flavoring. The advanced first cartridge head 2212 remains in place, thereby preventing outside air from entering the inside of the first cartridge part 221. In this manner, the second liquid flavoring or the third liquid flavoring can be precisely supplied to the aerosol product 201 according to an embodiment of the present invention.

[0097] In particular, referring to FIG. 7, an aerosol production article 201 according to one embodiment may include a humectant containing portion 2011, a medium containing portion 2012, and a filter portion 2013, in that order.

[0098] In one embodiment, the aerosol product 201 may be packaged in at least one wrapper. The humectant container 2011 may include a material that is waterproof, water-repellent, oil-repellent, or heat-resistant, such as aluminum foil. The medium container 2012 may include a tobacco medium, such as tobacco shreds or tobacco granules. The medium container 2012 may also include other additives, such as flavorings or organic acids. The humectant container 2011 includes a humectant, such as glycerin, propylene glycol (PG), and water. The humectant may further include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The filter portion 2013 may be composed of at least one segment and may include a cigarette filter wrapper surrounding the at least one segment. The filter portion 2013 includes at least one of a tube filter, a cooling structure, and a resase filter, but is not limited thereto.

[0099] Since the glycerin contained in the humectant has a large molecular weight, the humectant must be heated at a high temperature to aerosolize the glycerin. By including the humectant-containing portion 2011 containing a humectant in the aerosol product 201 according to the embodiment, the amount of humectant contained in the medium-containing portion 2012 can be reduced or the humectant can be removed from the medium-containing portion 2012, thereby lowering the heating temperature of the medium-containing portion 2012. Meanwhile, the humectant contained in the humectant-containing portion 2011 can maintain the moisture content in the aerosol generated upon heating at an appropriate level, soften the inherent tobacco taste, and enrich the amount of smoke.

[0100] In one embodiment, a heater 2123 is provided on at least a portion of the periphery of the article insertion portion 2121. The heater 2123 includes a first heater 2123-1 disposed around the humectant containing portion 2011 or a second heater 2123-2 disposed around the medium containing portion 2012. Here, the second heater 2123-2 that heats the medium containing portion 2012 may be omitted.

[0101] For example, the aerosol-generating device 200 according to one embodiment may use a first heater 2123-1 and a second heater 2123-2 to individually heat the humectant container 2011 and the medium container 2012. The first heater 2123-1 heats the humectant container 2011 to a first temperature range. The first temperature range may be 200°C to 300°C, preferably 200°C to 250°C. The second heater 2123-2 heats the tobacco medium to a second temperature range so that the nicotine contained in the medium container 2012 is aerosolized. The second temperature range may be 150°C to 200°C. However, the first temperature range and the second temperature range are not limited thereto.

[0102] Because the humectant-containing unit 2011 is located at the upstream end of the medium-containing unit 2012, when a user draws on a cigarette, air flowing in from the upstream end of the cigarette is heated by the first heater 2123-1 as it passes through the humectant-containing unit 2011, and the humectant (e.g., glycerin) is aerosolized. The air that has passed through the humectant-containing unit 2011 is heated by the second heater 2123-2 as it passes through the medium-containing unit 2012, and the medium (e.g., nicotine) is additionally aerosolized. Here, because the air flowing into the medium-containing unit 2012 is high-temperature air heated by the first heater 2123-1, the medium-containing unit 2012 absorbs heat not only from the second heater 2123-2 but also from the high-temperature air, thereby aerosolizing the air.

[0103] For example, the control unit (not shown) may be configured to identify the type of aerosol product 201 as well as whether it is inserted into the item insertion unit 2121. The control unit sends an activation signal to the actuator 230 in accordance with a liquid flavor combination ratio set according to the type of aerosol product 201, thereby allowing the set combination of liquid flavors to be supplied from the cartridge 220 to the moisturizer-containing unit 2011 of the aerosol product 201. The control unit heats the periphery of the moisturizer-containing unit 2011 at the heating temperature of the first heater 2123-1 set according to the type of aerosol product, thereby allowing an aerosol having a taste and vapor volume optimally combined according to the type of aerosol product 201 to be delivered to the user's mouse side via the filter unit 2013.

[0104] The above description of the embodiments is merely illustrative, and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible. Therefore, the scope of protection of the invention should be determined by the appended claims, and all differences within the scope equivalent to the content described in the claims should be construed as being included in the scope of protection defined by the claims.

[0105] The features and aspects of any embodiment described above can be combined with the features and aspects of any other embodiment unless an obvious technical conflict results.
