[0002] Recently, there has been a growing demand for alternative methods to overcome the shortcomings of conventional cigarettes. For example, there is a growing demand for systems that generate aerosols by heating cigarettes or aerosol-generating substances using an aerosol-generating device, rather than by burning the cigarette. Consequently, research into heated aerosol-generating devices is actively underway.

[0003] An aerosol generating device that generates aerosol by heating a liquid aerosol generating substance may include a vaporizer that stores the liquid aerosol generating substance. The vaporizer may be integrally formed with a main body of the aerosol generating device or detachably coupled to the aerosol generating device. Summary of the Invention

[0043] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings so that those skilled in the art can easily implement the present disclosure. However, the present disclosure can be implemented in various forms and is not limited to the embodiments described herein.

[0044] Hereinafter, an aerosol generating device according to an embodiment will be described with reference to the accompanying drawings.

[0045] Figure 1 FIG. 1 is a front view of an aerosol generating device combined with a vaporizer according to an embodiment.

[0046] Reference Figure 1 In one embodiment, a vaporizer 1 and a main body 2 are combined to operate as an aerosol generating device 100. For example, the vaporizer 1 can be combined with a region of the main body 2. The direction in which the vaporizer 1 is combined is not limited to the illustrated example; the vaporizer 1 can also be combined with the main body 2 along the length of the aerosol generating device 100.

[0047] In one embodiment, the aerosol generating device 100 may include a processor (not shown) and a battery (not shown). The battery and processor may be electrically connected to the vaporizer 1. For example, the battery and processor may supply power to the vaporizer 1 and control the vaporizer 1. Accordingly, the aerosol generating device 100 may heat a liquid or gel aerosol-generating substance stored in the vaporizer 1 to generate an aerosol.

[0048] In another embodiment, the aerosol generating device 100 may further include a housing and a separate heater (not shown), wherein the housing includes a space (not shown) for accommodating an aerosol generating article, and the separate heater heats the aerosol generating article accommodated in the housing.

[0049] For example, the space for accommodating the aerosol-generating article and the heater may be located in the main body 2. The vaporizer 1 may be incorporated into one area of ​​the main body 2, and the aerosol-generating article may be inserted into another area of ​​the main body 2.

[0050] The aerosol generating device 100 can generate aerosol not only by using the vaporizer 1 but also by using an inserted aerosol generating article, thereby realizing a hybrid aerosol generating device 100 .

[0051] In yet another embodiment, the aerosol generating device 100 may further include a detachable cover (not shown) for protecting at least a portion of the main body 2 and the vaporizer 1 coupled to the main body 2. The detachable cover may be coupled to one end of the aerosol generating device 100 where the vaporizer 1 is coupled to the main body 2. For example, the detachable cover may be detachable from / attached to the main body 2 when replacing the vaporizer 1.

[0052] Figure 2 yes Figure 1 The exploded perspective view of the carburetor shown, Figure 3 yes Figure 1 A bottom perspective view of the carburetor is shown.

[0053] Reference Figure 2 and Figure 3 The vaporizer 1 according to one embodiment may include a storage portion 10, a sealing portion 20, a core material 30, a heating element 40, a receiving portion 50, and a cover 60. The storage portion 10, the sealing portion 20, the core material 30, the heating element 40, the receiving portion 50, and the cover 60 may be combined along the z-axis direction shown.

[0054] For example, after the heating element 40 and the core material 30 are housed in the housing portion 50, the housing portion 50 can be inserted into the inner side of the lid 60, and the sealing portion 20 can be brought into contact with or coupled with the housing portion 50. Thus, the sealing portion 20 and the housing portion 50 can be located inside the lid 60. Finally, the storage portion 10 and the lid 60 are combined to form the vaporizer 1. However, the assembly sequence and assembly method of the vaporizer 1 are not limited to the above example.

[0055] The storage unit 10 can store an aerosol-generating substance. The storage unit 10 can store the aerosol-generating substance in a liquid state or a gel state. The aerosol-generating substance stored in the storage unit 10 is transferred to and absorbed by the core material 30. The aerosol-generating substance absorbed by the core material 30 can be heated by the heating element 40 and converted into an aerosol.

[0056] At least one area of ​​the storage portion 10 may be open. For example, the bottom surface of the storage portion 10 or at least a portion of the bottom surface may be open so that the aerosol-generating substance can easily move to the outside of the storage portion 10 by gravity.

[0057] According to one embodiment, the storage portion 10 may be combined with a sealing portion 20 to prevent leakage of the aerosol-forming substance. The sealing portion 20 may be coupled to at least one region of the storage portion 10 (e.g., an open surface of the storage portion 10) to form a storage space 12 capable of containing the aerosol-forming substance.

[0058] The sealing portion 20 can be made of a material that can be tightly combined with a portion of the storage portion 10. For example, the sealing portion 20 can be made of an elastic material such as rubber or silicone, but is not limited thereto.

[0059] The sealing portion 20 is tightly coupled to an area of ​​the storage portion 10 where the internal storage space 12 of the storage portion 10 is exposed, thereby preventing leakage of the aerosol-generating substance. Here, "tightly coupled" may mean that the sealing portion 20 is securely coupled to the storage portion 10 so as to prevent a gap from forming between the storage portion 10 and other components (e.g., between the storage portion 10 and the accommodating portion 50) that could allow leakage of the aerosol-generating substance.

[0060] In addition, the sealing portion 20 may be made to be coupled to / detached from the storage portion 10 , or may be made integrally with the storage portion 10 .

[0061] In order to allow the aerosol-generating substance stored in the storage portion 10 to move to the outside of the storage portion 10 when the storage portion 10 and the sealing portion 20 are combined, the sealing portion 20 may include at least one opening 22 .

[0062] For example, the inner side surface of the storage space 12 of the storage portion 10 is exposed to the outside through an open area, but the sealing portion 20 including the opening 22 may be coupled to an area of ​​the storage portion 10. Accordingly, the aerosol-generating substance stored in the storage space 12 of the storage portion 10 can move to the outside of the storage portion 10 through the opening 22 formed in the sealing portion 20, and the aerosol-generating substance stored in the storage portion 10 can be prevented from leaking to the outside of the storage portion 10 through gaps other than the opening 22.

[0063] The core material 30 can receive and absorb the aerosol-generating substance supplied from the storage unit 10. The core material 30 can have an elongated shape. For example, the core material 30 can have a cylindrical shape extending in one direction. Specifically, the core material 30 can have a polygonal prism shape, such as a cylinder, a quadrangular prism, or a triangular prism, but is not limited to the aforementioned examples. The core material 30 can also have a generally rod-shaped, needle-shaped, or planar shape.

[0064] A portion of the core material 30 can absorb the aerosol-generating substance supplied from the storage portion 10. For example, the aerosol-generating substance absorbed by a portion of the core material 30 can move to another portion of the core material 30 through capillary action. The core material 30 can include various types of materials. For example, the core material 30 can include at least one of cotton, ceramic, and glass fiber.

[0065] In one embodiment, the core material 30 may include a first end portion 31, a second end portion 33, and a central portion 32 between the first end portion 31 and the second end portion 33. The aerosol-generating substance supplied from the storage portion 10 may be absorbed by the core material 30 through the first end portion 31 and the second end portion 33. The aerosol-generating substance absorbed by the core material 30 may move toward the central portion 32 of the core material 30.

[0066] The heating element 40 can heat the aerosol-generating substance absorbed by the core material 30 to generate an aerosol. The heating element 40 can be arranged adjacent to the core material 30. The heating element 40 can heat the liquid aerosol-generating substance transferred to the central portion 32 of the core material 30 to generate an aerosol.

[0067] For example, the heating element 40 may be a coil-shaped resistance heater wound around the outer peripheral surface of the central portion 32 of the core material 30. As another example, the heating element 40 may be a resistance heater printed on the central portion 32 of the core material 30. The heating element 40 is not limited to the above example, and the heating element 40 may also be a porous element formed integrally with the core material 30.

[0068] The housing portion 50 may include housing spaces 51, 52, and 53 for housing the core material 30 and the heating element 40. For example, the housing portion 50 may include: at least one supporting groove 52 for supporting at least a portion of the core material 30; at least one storage groove 51 for temporarily storing an aerosol-generating substance so as to deliver the aerosol-generating substance to the core material 30; and a central space 53 for housing the central portion 32 of the core material 30.

[0069] The housing portion 50 and at least a portion of the sealing portion 20 form a cavity, and at least a portion of the core material 30 can be located in the cavity. The cavity can represent the space surrounded by the housing portion 50 and the sealing portion 20, which can represent the space where at least a portion of the core material 30 is located. For example, the central portion 32 of the core material 30 wrapped with the heating element 40 can be located in the cavity, and aerosol can be generated in the cavity.

[0070] In addition, external air can flow into the interior of the housing portion 50 through the inlet 56 included in at least a portion of the housing portion 50, and the aerosol generated in the cavity can be discharged to the outside of the housing portion 50 through the outlet 57 included in at least a portion of the housing portion 50.

[0071] The cover 60 may be combined with the receiving portion 50 and the sealing portion 20. The cover 60 may include an inner space 62 in which the receiving portion 50 and the sealing portion 20 may be disposed. For example, the cover 60 may include an inner space 62 having a shape corresponding to the outer shapes of the receiving portion 50 and the sealing portion 20. The receiving portion 50 and the sealing portion 20 disposed in the inner space 62 of the cover 60 can not only be aligned to match each other, but also be protected from external impacts by being surrounded by the cover 60.

[0072] The cover 60 may include a connecting passage 64 for guiding aerosol discharged from the discharge port 57 of the housing portion 50 to the exterior of the vaporizer 1. For example, when the housing portion 50 is disposed in the inner space 62 of the cover 60, the connecting passage 64 is located at a position corresponding to the discharge port 57, and the discharge port 57 may be connected to the connecting passage 64. The aerosol discharged to the exterior of the housing portion 50 through the discharge port 57 may move along the connecting passage 64 to the exterior of the vaporizer 1.

[0073] For example, the connecting passage 64 may be connected to the main body 2 of the aerosol generating device 100. The aerosol discharged to the outside of the housing 50 through the discharge port 57 may move to the main body 2 of the aerosol generating device 100 through the connecting passage 64 and be discharged to the outside of the aerosol generating device 100 along the air flow channel formed in the main body 2.

[0074] The cover 60 may include a connection terminal 66 for electrically connecting the vaporizer 1 and the main body 2. For example, the connection terminal 66 may be connected to the heating element 40 to mediate the connection between the battery and the processor included in the main body 2 and the heating element 40. Accordingly, the heating element 40 can be powered and controlled by the battery and the processor.

[0075] The storage portion 10 may include a plastic containing a polymer resin and a stability enhancing substance. For example, the storage portion 10 may be formed using a plastic containing a polymer resin and a stability enhancing substance. The polymer resin may refer to a main material contained in the plastic and may determine the basic properties of the plastic.

[0076] For example, the polymer resin may include one or more polymer resins selected from the group consisting of polyethylene glycol terephthalate (PCTG), polyethylene glycol-co-1,4-cyclohexanedimethanol terephthalate (PETG), styrene-acrylonitrile (SAN), poly(methyl methacrylate) (PMMA), and polystyrene (PS), but is not limited thereto. PS may include general-purpose polystyrene (GPPS) and / or high-impact polystyrene (HIPS). The polymer resin may be transparent so that the remaining amount of the aerosol-forming substance stored in the storage portion 10 can be confirmed. Furthermore, it may have thermal stability capable of withstanding heat generated when the aerosol-generating substance is heated and robustness capable of withstanding external impact.

[0077] Stability-enhancing substances can be mixed with polymer resins to improve the chemical stability of the plastic. Storage unit 10 must be chemically stable enough to store the aerosol-forming substance for extended periods of time. If storage unit 10 deforms due to external temperature and / or light conditions during storage, or reacts with the stored aerosol-forming substance, this can adversely affect the quality of the aerosol-forming substance. By mixing with the polymer resin, the stability-enhancing substance improves the chemical stability of the plastic, thereby preventing the degradation of the aerosol-forming substance's quality over time.

[0078] For example, the stability-enhancing substance may include polybutadiene. By mixing polybutadiene with the aforementioned polymer resins, it improves the chemical stability of the polymer resin, thereby preventing chemical structural deformation that may occur due to external temperature and / or light conditions. Furthermore, by inhibiting the reaction between the polymer resin and the aerosol-forming substance, the quality of the aerosol-forming substance can be maintained during storage.

[0079] Approximately 70% or more of the monomer units of polybutadiene may have a 1,2-structure. In addition to the aforementioned benefits, a polymer resin containing polybutadiene in which approximately 70% or more of its monomer units have a 1,2-structure can stably store the aerosol-forming substance regardless of the properties (e.g., polarity, volatility, etc.) of the fragrance contained therein. For example, approximately 80% or more of the monomer units of polybutadiene may have a 1,2-structure, or approximately 90% or more of the monomer units may have a 1,2-structure, but the present invention is not limited thereto.

[0080] The plastic may include about 0.1% to about 5% by weight of a stability enhancing substance based on the total weight of the plastic. The stability enhancing substance within the range of about 0.1% to about 5% by weight can improve the stability of the chemical structure of the plastic while providing transparency. In the case where the stability enhancing substance is included in an amount less than about 0.1% by weight based on the total weight of the plastic, the effect of improving the stability of the plastic may be insufficient. In the case where the stability enhancing substance exceeds about 5% by weight based on the total weight of the plastic, the transparency of the plastic may be insufficient. In addition, the stability enhancing substance may be included in an amount of about 0.5% to about 3% by weight, or about 0.7% to about 2% by weight based on the total weight of the plastic.

[0081] The plastic may also include biomass. Since the biomass is included in the plastic, the decomposability of the vaporizer 1 after use can be improved during the disposal process. For example, the biomass may be lignocellulosic biomass, but is not limited thereto.

[0082] The plastic may include about 0.01% to about 5% by weight of biomass based on the total weight of the plastic. In the range of about 0.01% to about 5% by weight of biomass, the decomposability during the discarding process can be improved without compromising the stability of the chemical structure of the plastic. In the case where the biomass is less than about 0.01% by weight based on the total weight of the plastic, the decomposability of the plastic during the discarding process may be insufficient. In the case where the biomass exceeds about 5% by weight based on the total weight of the plastic, the stability of the chemical structure of the plastic may be compromised. In addition, the biomass may be included in an amount of about 0.1% to about 3% by weight, or about 0.5% to about 1% by weight based on the total weight of the plastic.

[0083] The aerosol-generating substance may further include a fragrance. Due to its excellent stability, the plastic material included in the storage portion 10 of the vaporizer 1 can stably store the fragrance without being restricted by the properties (eg, polarity, volatility, etc.) of the fragrance.

[0084] The lid 60 may be made of the same plastic as the storage portion 10. When the lid 60 is made of the same material as the storage portion 10, the bonding strength between the lid 60 and the storage portion 10 can be improved. For example, the plastic may include PCTG as a polymer resin and may include approximately 1% by weight of polybutadiene as a stability-enhancing substance based on the total weight of the polymer resin. The lid 60 and the storage portion 10 may be formed using the same plastic. However, the plastics included in the lid 60 and the storage portion 10 are not limited thereto, and the aforementioned polymer resins and stability-enhancing substances may be used without limitation.

[0085] Furthermore, components of the vaporizer 1 other than the cover 60 and the storage portion 10 may also be made of the same plastic. For example, the storage portion 10, the cover 60, the sealing portion 20, and the receiving portion 50 may be made of the same plastic, but the invention is not limited thereto.

[0086] Experimental Example 1: Chemical Structure Stability Analysis Plastics are produced by varying the type of polymer resin (PCTG, SAN, PMMA, GPPS), the content of the polymer resin, and the stability-enhancing substance. The stability-enhancing substance used is polybutadiene, where more than 90% of the monomer units have a 1,2-structure.

[0087] To confirm the chemical stability of the prepared plastic, the amount of captured gas was analyzed using thermal desorption gas chromatography. Thermal desorption pretreatment was performed at a heating temperature of 200°C, and the generated gas was captured for 60 minutes. A value indicating a captured gas amount below the reference value is marked with an "O," while a value exceeding the reference value is marked with an "X." The results are summarized in Table 1 below.

[0088] Experimental Example 2: Stability Analysis of Aerosol-Forming Substances A vaporizer was manufactured using the plastic prepared in Experimental Example 1. An aerosol-forming substance including 100 wt % of glycerin was stored in a storage portion of the vaporizer.

[0089] To analyze the stability of glycerin stored in a vaporizer, the vaporizer was left at room temperature for four weeks, after which the viscosity of the glycerin was measured. Values ​​indicating a difference between the measured viscosity and the initial viscosity of the vaporizer was less than the reference value were marked with a circle (○), while values ​​indicating a difference exceeding the reference value were marked with a cross (×). The results are shown in Table 1 below.

[0090] [Table 1]

[0091] Referring to Table 1, it can be confirmed that the structural stability of plastics containing stability-enhancing substances is improved compared to plastics without stability-enhancing substances. Furthermore, it can be confirmed that the stability of glycerin stored in a vaporizer is improved when the plastic contains 1% by weight of the stability-enhancing substance compared to plastics without the substance. Furthermore, similar to the plastics without the substance, no effect of improving the stability of glycerin stored in a vaporizer is observed when the plastic contains 5% by weight of the stability-enhancing substance. However, as with the plastics without the substance, it is expected that the inherent properties of the stability-enhancing substance become stronger as the content of the stability-enhancing substance increases.

[0092] Experimental Example 3: Stability Analysis of Flavors A vaporizer was manufactured using a plastic material consisting of 99% by weight PCTG and 1% by weight polybutadiene. Glycerin, which contains fragrance, was stored in the vaporizer's storage area. Polybutadiene was used in which at least 70% of its monomer units had a 1,2-structure, and in which less than 70% of its monomer units had a 1,2-structure. To analyze the stability of the fragrance stored in the vaporizer, the vaporizer was left at room temperature for four weeks, followed by a sensory evaluation. The sensory evaluation was conducted on 15 men and women aged 20 to 45. After inhaling the aerosol produced by the vaporizer, the participants rated the palatability of the aroma on a scale of 1 to 5. Table 2 below shows the average sensory evaluation scores.

[0093] [Table 2]

[0094] Referring to Table 2, it can be confirmed that polybutadiene containing 70% or more of its monomer units has a 1,2-structure has higher palatability than polybutadiene containing 70% or less of its monomer units having a 1,2-structure. This is presumably due to a smaller loss of volatilized flavoring. This indicates that polybutadiene containing 70% or more of its monomer units having a 1,2-structure can more stably store flavorings when incorporated into plastic.

[0095] Hereinafter, an aerosol generating device including a vaporizer and an aerosol generating article usable with the aerosol generating device according to another embodiment will be described.

[0096] Figure 4 and Figure 5 1 is a diagram showing an example in which an aerosol-generating article is inserted into an aerosol-generating device.

[0097] Reference Figure 4 and Figure 5 The aerosol generating device 100 includes a battery 110, a control unit 120, a heater 130, and a vaporizer 140. In addition, an aerosol generating article 200 may be inserted into the internal space of the aerosol generating device 100.

[0098] Figure 4 and Figure 5 The illustrated aerosol-generating device 100 includes a vaporizer, but the embodiments are not limited to such an implementation of the aerosol-generating device, and the vaporizer may be omitted from the aerosol-generating device 100. In the case where the vaporizer is omitted from the aerosol-generating device 100, the aerosol-generating article 200 includes an aerosol-generating substance, and when the aerosol-generating article 200 is heated by the heater 130, the aerosol-generating article 200 may generate an aerosol.

[0099] Figure 4 and Figure 5 The aerosol generating device 100 shown in FIG. 1 shows the components related to this embodiment. Therefore, as long as a person with ordinary knowledge in the technical field related to this embodiment will understand, the aerosol generating device 100 may also include components other than Figure 4 and Figure 5 Other common components other than the components shown in the figure.

[0100] also, Figure 4 and Figure 5 1 and 2 , the aerosol generating device 100 includes a heater 130 . However, the heater 130 may be omitted as needed.

[0101] Figure 4 1 shows a case where the battery 110, the control unit 120, the vaporizer 140 and the heater 130 are arranged in a row. Figure 5 FIG shows a case where the vaporizer 140 and the heater 130 are arranged in parallel. However, the internal structure of the aerosol generating device 100 is not limited to Figure 4 or Figure 5 In other words, the arrangement of the battery 110 , the control unit 120 , the vaporizer 140 , and the heater 130 may be changed according to the design of the aerosol generating device 100 .

[0102] If the aerosol-generating article 200 is inserted into the aerosol-generating device 100, the aerosol-generating device 100 operates the vaporizer 140, thereby generating an aerosol from the vaporizer 140. The aerosol generated by the vaporizer 140 passes through the aerosol-generating article 200 and is delivered to the user. The vaporizer 140 will be described in more detail below.

[0103] The battery 110 supplies power for operating the aerosol generating device 100. For example, the battery 110 can supply power to heat the heater 130 or the vaporizer 140, and can also supply power required for operating the control unit 120. Furthermore, the battery 110 can supply power required for operating a display, sensors, a motor, and the like provided in the aerosol generating device 100.

[0104] The control unit 120 controls the overall operation of the aerosol generating device 100. Specifically, the control unit 120 controls not only the operation of the battery 110, the heater 130, and the vaporizer 140, but also the operation of other components included in the aerosol generating device 100. Furthermore, the control unit 120 can also determine whether the aerosol generating device 100 is in an operable state by confirming the status of each component of the aerosol generating device 100.

[0105] The control unit 120 includes at least one processor. The processor can be implemented as an array of multiple logic gates or as a combination of a general-purpose microprocessor and a memory storing programs executable by the microprocessor. Furthermore, anyone with ordinary knowledge in the technical field of this embodiment will appreciate that the processor can also be implemented as other forms of hardware.

[0106] The heater 130 may be heated by the power supplied from the battery 110. For example, if the aerosol-generating article 200 is inserted into the aerosol-generating device 100, the heater 130 may be located outside the aerosol-generating article 200. Thus, the heated heater 130 may increase the temperature of the aerosol-generating substance in the aerosol-generating article 200.

[0107] The heater 130 may be a resistive heater. For example, the heater 130 may include a conductive track, and the heater 130 may be heated by the flow of current in the conductive track. However, the heater 130 is not limited to the above example and may be used in any manner as long as it can heat to a desired temperature. The desired temperature may be pre-set in the aerosol generating device 100 or set by the user.

[0108] In addition, as another example, the heater 130 may be an induction heating heater. Specifically, the heater 130 may include a conductive coil for heating the aerosol-generating article by induction heating, and the aerosol-generating article may include a susceptor that can be heated by the induction heating heater.

[0109] Figure 4 and Figure 5The heater 130 is shown as being disposed outside the aerosol-generating article 200, but the present invention is not limited thereto. For example, the heater 130 may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and may heat the inside or outside of the aerosol-generating article 200 depending on the shape of the heating element.

[0110] In addition, the aerosol generating device 100 may also be provided with a plurality of heaters 130. In this case, the plurality of heaters 130 may be arranged to be inserted into the interior of the aerosol generating article 200 or may be arranged outside the aerosol generating article 200. In addition, a portion of the plurality of heaters 130 may be arranged to be inserted into the interior of the aerosol generating article 200, and the remaining portion may be arranged outside the aerosol generating article 200. In addition, the shape of the heater 130 is not limited to Figure 4 and Figure 5 The shape shown can be made into many shapes.

[0111] The vaporizer 140 can generate an aerosol by heating the liquid composition, and the generated aerosol can be transmitted to the user through the aerosol-generating article 200. In other words, the aerosol generated by the vaporizer 140 can move along the airflow channel of the aerosol-generating device 100, and the airflow channel can be configured to enable the aerosol generated by the vaporizer 140 to pass through the aerosol-generating article 200 and be transmitted to the user.

[0112] For example, the vaporizer 140 may include a liquid storage portion, a liquid transmission component, and a heating element, but is not limited thereto. For example, the liquid storage portion, the liquid transmission component, and the heating element may also be included in the aerosol generating device 100 as independent modules.

[0113] The liquid storage portion can store a liquid composition. For example, the liquid composition can be a liquid containing a tobacco substance including volatile tobacco flavor components, or a liquid containing a non-tobacco substance. The liquid storage portion can be detachable from or attachable to the vaporizer 140, or can be integrally formed with the vaporizer 140.

[0114] For example, the liquid composition may include water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. The fragrance may include, but is not limited to, menthol, peppermint, spearmint oil, various fruity ingredients, and the like. The flavoring agent may include, but is not limited to, an ingredient that can provide a variety of aromas or flavors to the user. The vitamin mixture may be, but is not limited to, a mixture containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E. In addition, the liquid composition may include an aerosol former such as glycerin and propylene glycol.

[0115] The liquid delivery member can deliver the liquid composition of the liquid storage portion to the heating element. For example, the liquid delivery member can be a wick such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, etc., but is not limited thereto.

[0116] The heating element is a component used to heat the liquid composition being transported by the liquid delivery member. For example, the heating element may be a metal hot wire, a metal hot plate, a ceramic heater, or the like, but is not limited thereto. Alternatively, the heating element may be constructed using a conductive filament such as a nichrome wire, and may be arranged so as to be wound around the liquid delivery member. The heating element is heated by the supply of electric current and transfers heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol can be generated.

[0117] For example, the vaporizer 140 may be referred to as a cartomizer or an atomizer, but is not limited thereto.

[0118] The aerosol generating device 100 may also include common components other than the battery 110, the control unit 120, the heater 130, and the vaporizer 140. For example, the aerosol generating device 100 may include a display capable of outputting visual information and / or a motor for outputting tactile information. Furthermore, the aerosol generating device 100 may include at least one sensor (such as a puff sensor, a temperature sensor, or an aerosol-generating article insertion sensor). Furthermore, the aerosol generating device 100 may be configured to allow external air to flow in or internal gas to flow out even when the aerosol-generating article 200 is inserted.

[0119] Although Figure 4 and Figure 5 Although not shown, the aerosol generating device 100 may also be combined with a separate bracket to form a system. For example, the bracket may be used to charge the battery 110 of the aerosol generating device 100. Alternatively, the heater 130 may be heated while the bracket is coupled to the aerosol generating device 100.

[0120] The aerosol-generating article 200 can be similar to a conventional combustion-type cigarette. For example, the aerosol-generating article 200 can be divided into a first portion including an aerosol-generating substance and a second portion including a filter, etc. Alternatively, the second portion of the aerosol-generating article 200 can also include an aerosol-generating substance. For example, the aerosol-generating substance in the form of particles or capsules can be inserted into the second portion.

[0121] The entire first portion may be inserted into the aerosol generating device 100, while the second portion is exposed to the outside. Alternatively, only a portion of the first portion may be inserted into the aerosol generating device 100, or portions of both the first and second portions may be inserted. The user can inhale the aerosol while holding the second portion in their mouth. In this case, aerosol is generated as external air passes through the first portion, and the generated aerosol is then delivered to the user's mouth via the second portion.

[0122] As an example, external air can flow in through at least one air channel formed in the aerosol-generating device 100. For example, the opening and / or size of the air channel formed in the aerosol-generating device 100 can be adjusted by the user. Thus, the user can adjust the amount of atomization, the puffing sensation, and the like. As another example, external air can also flow into the interior of the aerosol-generating article 200 through at least one hole formed in the surface of the aerosol-generating article 200.

[0123] Below, refer to Figure 6 and Figure 7 , illustrating an example of an aerosol-generating article 200.

[0124] Figure 6 and Figure 7 is a diagram illustrating an example of an aerosol-generating article.

[0125] Reference Figure 6 , the aerosol generating article 200 includes a tobacco rod 210 and a filter rod 220. Figure 4 and Figure 5 The first part includes a tobacco rod 210 , and the second part includes a filter rod 220 .

[0126] Figure 6 The filter rod 220 is shown as a single segment, but the present invention is not limited thereto. Alternatively, the filter rod 220 may be composed of multiple segments. For example, the filter rod 220 may include a first segment for cooling the aerosol and a second segment for filtering predetermined components within the aerosol. Furthermore, the filter rod 220 may also include at least one segment for performing other functions, as needed.

[0127] The aerosol-generating article 200 may be packaged in at least one package 240. The package 240 may have at least one hole formed therein for allowing external air to flow in or internal gas to flow out. As one example, the aerosol-generating article 200 may be packaged in one package 240. As another example, the aerosol-generating article 200 may be packaged in two or more packages 240 stacked on top of each other. For example, the tobacco rod 210 may be packaged in a first package 241, and the filter rod 220 may be packaged in packages 242, 243, and 244. Furthermore, the entire aerosol-generating article 200 may be further packaged in a single package 245. If the filter rod 220 is composed of multiple segments, each segment may be packaged in a package 242, 243, and 244.

[0128] The tobacco rod 210 includes an aerosol-generating substance. For example, the aerosol-generating substance may include at least one of, but is not limited to, glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Furthermore, the tobacco rod 210 may contain other additives such as flavorings, humectants, and / or organic acids. Furthermore, flavoring liquids such as menthol or humectants may be added to the tobacco rod 210 by spraying the tobacco rod 210.

[0129] The tobacco rod 210 can be made in a variety of ways. For example, the tobacco rod 210 can be made from a sheet or a strand. Furthermore, the tobacco rod 210 can also be made from cut tobacco obtained by shredding tobacco sheets. Furthermore, the tobacco rod 210 can be surrounded by a heat-conductive material. For example, the heat-conductive material can be a metal foil such as aluminum foil, but is not limited thereto. As an example, the heat-conductive material surrounding the tobacco rod 210 can evenly distribute the heat transferred to the tobacco rod 210, thereby increasing the thermal conductivity applied to the tobacco rod and thus improving the flavor of the tobacco. Furthermore, the heat-conductive material surrounding the tobacco rod 210 can function as a base heated by the induction heating heater. In this case, although not shown in the figure, the tobacco rod 210 can also include an additional base in addition to the heat-conductive material surrounding the exterior.

[0130] Filter rod 220 can be a cellulose acetate filter. Furthermore, the shape of filter rod 220 is not limited. For example, filter rod 220 can be cylindrical or hollow. Furthermore, filter rod 220 can be a concave rod. If filter rod 220 is composed of multiple segments, at least one of the multiple segments can also be manufactured in other shapes.

[0131] The filter rod 220 can also be made to produce a flavor. As an example, the flavoring liquid can be sprayed onto the filter rod 220, or a separate fiber coated with the flavoring liquid can be inserted into the interior of the filter rod 220.

[0132] Furthermore, filter rod 220 may include at least one capsule 230. Capsule 230 may generate a fragrance or aerosol. For example, capsule 230 may be a structure in which a liquid containing a fragrance is wrapped in a film. Capsule 230 may have a spherical or cylindrical shape, but is not limited thereto.

[0133] If the filter rod 220 includes an aerosol cooling segment, the cooling segment can be made of a polymer or a biodegradable polymer. For example, the cooling segment can be made solely of pure polylactic acid, but is not limited thereto. Alternatively, the cooling segment can be made of a cellulose acetate filter perforated with multiple holes. However, the cooling segment is not limited to the above examples; any cooling segment is applicable without limitation as long as it can perform the function of cooling the aerosol.

[0134] Reference Figure 7 The aerosol generating article 300 may further include a front plug 330. The front plug 330 may be located on the side of the tobacco rod 310 opposite to the filter rod 320. The front plug 330 can prevent the tobacco rod 310 from being detached from the outside and can prevent the liquefied aerosol from the tobacco rod 310 from flowing into the aerosol generating device 100 ( Figures 4 and 5 ).

[0135] The filter rod 320 may include a first segment 321 and a second segment 322. Here, the first segment 321 may correspond to Figure 6 The first segment of the filter rod 220, the second segment 322 may correspond to Figure 6 The third segment of the filter rod 220.

[0136] The diameter and overall length of the aerosol-generating article 300 may correspond to Figure 6 The diameter and overall length of the aerosol-generating article 200 may be determined by the method of claim 1. For example, the front plug 330 may be about 7 mm long, the tobacco rod 310 may be about 15 mm long, the first segment 321 may be about 12 mm long, and the second segment 322 may be about 14 mm long, but are not limited thereto.

[0137] The aerosol-generating article 300 may be packaged in at least one package 350. The package 350 may have at least one hole formed therein to allow external air to flow in or internal gas to flow out. For example, the front end plug 330 may be packaged in a first package 351, the tobacco rod 310 may be packaged in a second package 352, the first segment 321 may be packaged in a third package 353, and the second segment 322 may be packaged in a fourth package 354.

[0138] Furthermore, the aerosol generating article 300 as a whole may be further packaged in a fifth package 355. In addition, at least one perforation 360 may be formed in the fifth package 355. For example, the perforation 360 may be formed in a region surrounding the tobacco rod 310, but is not limited thereto. The perforation 360 may be formed to allow the aerosol generating article 300 to be packaged in a fifth package 355. Figure 5 and Figure 6 The heater 130 shown acts to transfer heat to the interior of the tobacco rod 310 .

[0139] Furthermore, the second segment 322 may include at least one capsule 340. Capsule 340 may generate fragrance or aerosol. For example, capsule 340 may be a structure in which a liquid containing fragrance is encapsulated in a film. Capsule 340 may have a spherical or cylindrical shape, but is not limited thereto.

[0152] The battery 840 can supply the power required for the operation of the aerosol generating device 800. The battery 840 can also supply the power required to heat the heater 850. Furthermore, the battery 840 can also supply the power required for the operation of other components within the aerosol generating device 800 (e.g., the sensor 820, the output unit 830, the user input unit 860, the memory 870, and the communication unit 880).

Furthermore, if the aerosol generating device 800 generates aerosol using induction heating, the aerosol generating device 800 may further include a direct current / alternating current (DC / AC) converter for converting the DC power of the battery 840 into alternating current (AC) power.

[0154] The control part 810, the sensing part 820, the output part 830, the user input part 860, the memory 870, and the communication part 880 may receive power from the battery 840 to perform functions. Figure 8Although not shown, a power conversion circuit, such as a low dropout (LDO) circuit or a voltage regulator circuit, which converts the power of the battery 840 and supplies the converted power to each component may be further included.

Furthermore, heater 850 can be implemented using, but is not limited to, metal heating wires, metal heating plates with conductive tracks, or ceramic heating elements.

[0156] In another embodiment, the heater 850 may be an induction heating heater, for example, the heater 850 may include a base that generates heat by a magnetic field applied by a coil, thereby heating the aerosol-forming substance.

[0157] The user input unit 860 may receive information input from the user or may output information to the user. For example, the user input unit 860 may include a keypad, a dome switch, a touchpad (contact capacitance method, pressure resistance film method, infrared sensing method, surface ultrasonic wave conduction method, integral tension measurement method, piezoelectric effect method, etc.), a wheel, a roller switch, etc., but is not limited thereto. In addition, although Figure 8 Although not shown in the figure, the aerosol generating device 800 may further include a connection interface such as a universal serial bus (USB) interface, and may be connected to other external devices through the connection interface such as the USB interface to transmit and receive information, or to charge the battery 840.

[0158] Memory 870 is hardware that stores various data processed within aerosol generating device 800. It can store data processed by control unit 810 and data to be processed. Memory 870 can include at least one type of storage medium selected from the group consisting of flash memory, hard disk, multimedia card micro, card-type memory (e.g., secure digital (SD) or extreme digital (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 storage, magnetic disk, and optical disk. Memory 870 can store information such as the operating time of aerosol generating device 800, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data specific to the user's smoking patterns.

[0159] The communication unit 880 may include at least one component for communicating with another electronic device. For example, the communication unit 880 may include a short-range communication unit 882 and a wireless communication unit 884.

[0162] The control unit 810 can control the overall operation of the aerosol generating device 800. In one embodiment, the control unit 810 may include at least one processor. The processor may be implemented as an array of multiple logic gates, or as a combination of a general-purpose microprocessor and a memory, wherein the memory stores programs executable by the microprocessor. Furthermore, as will be understood by those with ordinary knowledge in the technical field to which this embodiment relates, the processor may also be implemented as other forms of hardware.

[0163] The control unit 810 can control the temperature of the heater 850 by controlling the supply of power from the battery 840 to the heater 850. For example, the control unit 810 can control the power supply by controlling the switching of a switching element between the battery 840 and the heater 850. In another example, the power supply from the heating integrated circuit to the heater 850 can also be controlled according to a control command from the control unit 810.

[0164] The control unit 810 can analyze the results sensed by the sensing unit 820 and control the processing to be performed. For example, the control unit 810 can control the power supplied to the heater 850 based on the results sensed by the sensing unit 820 to start or end the operation of the heater 850. As another example, the control unit 810 can control the amount of power supplied to the heater 850 and the power supply time based on the results sensed by the sensing unit 820 so that the heater 850 can be heated to a predetermined temperature or maintained at an appropriate temperature.

[0165] The control unit 810 may control the output unit 830 based on the result sensed by the sensing unit 820. For example, if the number of puffs counted by the puff sensor 826 reaches a preset number, the control unit 810 may notify the user in advance through at least one of the display unit 832, the tactile unit 834, and the sound output unit 836 that the aerosol generating device 800 is about to be terminated.
