[0045] When selecting the terms used in the embodiments, the functions in the embodiments of the present disclosure are considered to select from the widely used general terms. However, these terms may differ according to the intentions, precedents, new technologies, etc. of those skilled in the art. In certain cases, the applicant of the present disclosure may also arbitrarily select terms, and the corresponding parts in the specific description describe the meanings of these terms in detail. Therefore, the terms used in the present disclosure do not refer only to the names of the terms, but are defined according to the meanings of the terms and the overall content of the present disclosure.

[0046] It should be understood that when a part "includes" a component, it means that other components may be included without special mention of counterexamples, and does not mean that other components are excluded. The terms "-unit", "-module" and the like described in the specification refer to a part that processes at least one function or operation, and the part may be implemented as hardware, software, or a combination of hardware and software.

[0047] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings so that the embodiments can be easily implemented by those skilled in the art. However, the embodiments can be implemented in various different forms, and the present disclosure is not limited to the embodiments described herein.

[0048] Figure 1 FIG. 1 is a diagram showing an aerosol generating device according to an embodiment. Figure 2 FIG. 1 is a diagram showing an aerosol generating device according to an embodiment. Figure 3 FIG. 1 is a diagram showing an aerosol generating device according to an embodiment.

[0049] Reference Figure 1 The aerosol generating device 1 may include a battery 11, a controller 12 and a heater 13. Figure 2 as well as Figure 3 The aerosol generating device 1 may further include a vaporizer 14. The aerosol generating article 2 may be inserted into the inner space of the aerosol generating device 1.

[0050] Figures 1 to 3 The aerosol generating device 1 shown may include components related to the embodiments described herein. Therefore, it should be understood by a person skilled in the art that, in addition to Figures 1 to 3 In addition to the components shown, the aerosol generating device 1 may also include other common components.

[0051] Figure 2 and Figure 3 The aerosol generating device 1 in the embodiment is shown to include a heater 13 , but the heater 3 may be omitted as required.

[0052] Figure 1 The battery 11, controller 12, and heater 13 are shown to be arranged linearly. Figure 2 A linear configuration of the battery 11 , the controller 12 , the vaporizer 14 , and the heater 13 is shown. Figure 3 The vaporizer 14 and the heater 13 are shown to be arranged in parallel. However, the internal structure of the aerosol generating device 1 is not limited to Figures 1 to 3 In other words, the configurations of the battery 11 , the controller 12 , the heater 13 , and the vaporizer 14 may be changed according to the design of the aerosol generating device 1 .

[0053] When the aerosol generating article 2 is inserted into the aerosol generating device 1, the aerosol generating device 1 can operate the heater 13 and / or the vaporizer 14 to generate aerosol. The aerosol generated by the heater 13 and / or the vaporizer 14 passes through the aerosol generating article 2 and is transferred to the user.

[0054] When the aerosol generating product 2 is not inserted into the aerosol generating device 1 , the aerosol generating device 1 may heat the heater 13 as necessary.

[0055] The battery 11 can provide the power required for the aerosol generating device 1 to operate. For example, the battery 11 can provide power to heat the heater 13 or the vaporizer 14, and can provide power required for the controller 12 to operate. The battery 11 can provide power required for the display, sensor, motor, etc. installed in the aerosol generating device 1 to operate.

[0056] The controller 12 may control the overall operation of the aerosol generating device 1. Specifically, the controller 12 may control not only the battery 11, the heater 13, and the vaporizer 14, but also the operations of other components included in the aerosol generating device 1. The controller 12 may determine whether the aerosol generating device 1 is in an operable state by confirming the state of each of the components of the aerosol generating device 1.

[0057] The controller 12 may include at least one processor. The at least one processor may be implemented as a plurality of logic gate arrays, or may be implemented as a combination of a general-purpose microprocessor and a memory, wherein the memory stores a program executable by the microprocessor. It should be understood by those skilled in the art that the at least one controller may be implemented in other forms of hardware.

[0058] The heater 13 may be heated by the power supplied by the battery 11. For example, when the aerosol-generating product is inserted into the aerosol-generating device 1, the heater 13 may be located outside the aerosol-generating product. Thus, the heated heater 13 may increase the temperature of the aerosol-generating substance in the aerosol-generating product.

[0059] The heater 13 may be a resistive heater. For example, the heater 13 may include a conductive track, and as current flows on the conductive track, the heater 13 may be heated. However, the heater 13 is not limited to the above example, and any example of heating the heater 13 to a desired temperature may be applied without limitation. Here, the desired temperature may be pre-set in the aerosol generating device 1, or may be set by a user.

[0060] The heater 13 may be an induction heater. Specifically, the heater 13 may include a wire coil that heats the aerosol-generating article by induction heating, and the aerosol-generating article may include a susceptor that can be heated by the induction heater.

[0061] For example, the heater 13 may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element or a rod-shaped heating element, and the inside or outside of the aerosol-generating article 2 may be heated according to the shape of the heating element.

[0062] The heater 13 may be provided in the aerosol generating device 1 in the form of a plurality of heaters. In this case, the plurality of heaters 13 may be inserted into the aerosol generating article 2 or may be arranged outside the aerosol generating article 2. Some of the plurality of heaters 13 may be arranged to be inserted into the aerosol generating article 2, while the remaining heaters may be arranged outside the aerosol generating article 2. The shape of the heater 13 is not limited to Figures 1 to 3 The shape in the figure can also be made into a variety of shapes.

[0063] The vaporizer 14 can heat the liquid composition to generate an aerosol, and the generated aerosol can be delivered to the user through the aerosol generating article 2. In other words, the aerosol generated by the vaporizer 14 can move along the airflow path of the aerosol generating device 1, and the airflow path can be configured so that the aerosol generated by the vaporizer 14 can be delivered to the user through the aerosol generating article.

[0064] For example, the vaporizer 14 may include a liquid storage portion, a liquid delivery device, and a heating element. However, the embodiment is not limited thereto. For example, the liquid storage portion, the liquid delivery device, and the heating element may be included in the aerosol generating device 1 as independent modules.

[0065] The liquid storage portion can store a liquid composition. For example, the liquid composition can be a liquid comprising a tobacco-containing substance containing a volatile tobacco aromatic component, or a liquid comprising a non-tobacco substance. The liquid storage portion can be manufactured to be detachable from the vaporizer 14 and attached to the vaporizer 14, or can be formed as one with the vaporizer 14.

[0066] For example, the liquid composition may include water, solvent, ethanol, plant extract, spices, flavoring agents, or vitamin mixtures. Spices may include menthol, mint, spearmint oil, various fruit flavor ingredients, etc. However, embodiments are not limited thereto. The flavoring agent may include ingredients that provide different fragrances or tastes to the user. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C, or vitamin E. However, embodiments are not limited thereto. In addition, the liquid composition may include aerosol forming agents such as glycerol and propylene glycol.

[0067] The liquid delivery device can transfer the liquid composition of the liquid storage portion to the heating element. For example, the liquid delivery device can be, for example, a wick, such as cotton fiber, ceramic fiber, glass fiber, or a porous ceramic wick. However, the embodiment is not limited thereto.

[0068] The heating element can be an element configured to heat the liquid composition transported by the liquid delivery device. For example, the heating element can be a metal heating wire, a metal heating plate, a ceramic heater, etc. However, embodiments are not limited thereto. The heating element can include conductive wires such as nickel-chromium alloy wires, and can be arranged to wrap around the structure of the liquid delivery device. The heating element can be heated by supplying electric current, and heat can be transferred to the liquid composition in contact with the heating element, so that the liquid composition can be heated. Aerosol can eventually be generated.

[0069] For example, the vaporizer 14 may also be referred to as a cartomizer or an atomizer. However, the embodiment is not limited thereto.

[0070] Meanwhile, in addition to the battery 11, the controller 12, the heater 13, and the vaporizer 14, the aerosol generating device 1 may also include other common components. For example, the aerosol generating device 1 may also include a display that outputs visual information and / or a motor that outputs tactile information. The aerosol generating device 1 may include at least one sensor (e.g., a suction sensor, a temperature sensor, an aerosol generating product insertion detection sensor, etc.). The aerosol generating device 1 may also be made to have a structure that allows external air to be introduced or internal gas to flow out, even in a state where the aerosol generating product 2 is inserted.

[0071] although Figures 1 to 3 Although not shown in the figure, the aerosol generating device 1 can form a system together with a separate bracket. For example, the bracket can be used to charge the battery 11 of the aerosol generating device 1. The bracket can also be used to heat the heater 13 when the bracket is connected to the aerosol generating device 1.

[0072] The aerosol-generating article 2 can be similar to a conventional combustion-type cigarette. For example, the aerosol-generating article 2 can be divided into a first portion including an aerosol-generating substance and a second portion including a filter element, etc. The second portion of the aerosol-generating article 2 can also include an aerosol-generating substance. For example, the aerosol-generating substance in the form of particles or capsules can also be inserted into the second portion.

[0073] The first part may be completely inserted into the aerosol generating device 1, and the second part may be exposed to the outside. Only the first part may be partially inserted into the aerosol generating device 1, or the first part may be completely inserted into the aerosol generating device 1 and the second part may be partially inserted into the aerosol generating device 1. The user may inhale the aerosol while biting the second part with the mouth. At this time, as the external air flows through the first part to generate the aerosol, the generated aerosol may flow through the second part and be delivered to the user's mouth.

[0074] For example, external air can be introduced through at least one air channel formed in the aerosol generating device 1. In this example, the user can adjust the opening and closing of the air channel formed in the aerosol generating device 1 and / or the size of the air channel. Thus, the user can adjust the amount of atomization, the taste of smoking, etc. External air can also be introduced into the interior of the aerosol generating article 2 through at least one hole formed on the surface of the aerosol generating article 2.

[0075] Figure 4 FIG. 1 is a diagram showing an aerosol generating device according to an embodiment.

[0076] Reference Figure 4 , the aerosol generating article 2 comprises a tobacco rod 21 and a filter rod 22. Figures 1 to 3 The first and second parts of the illustration may include a tobacco rod 21 and a filter rod 22, respectively.

[0077] Figure 4 The filter rod 22 shown has only a single section, but the embodiment is not limited thereto. In other words, alternatively, the filter rod 22 can also include multiple sections. For example, the filter rod 22 can include a section for cooling the aerosol and a section for filtering the predetermined components contained in the aerosol. The filter rod 22 can also include at least one section that performs other functions.

[0078] The diameter of the aerosol-generating article 2 may be in the range of 5 mm to 9 mm, and the length of the aerosol-generating article 2 may be about 48 mm. However, embodiments are not limited thereto. For example, the length of the tobacco rod 21 may be about 12 mm, the length of the first section of the filter rod 22 may be about 10 mm, the length of the second section of the filter rod 22 may be about 14 mm, and the length of the third section of the filter rod 22 may be about 12 mm. However, embodiments are not limited thereto.

[0079] The aerosol generating product 2 may be packaged by at least one package 24. The package 24 may have at least one hole for allowing external air to be introduced or internal gas to flow out. For example, the aerosol generating product 2 may be packaged by one package 24. For another example, the aerosol generating product 2 may also be packaged by two or more packages 24 in a stacked manner. For example, the tobacco rod 21 is packaged by a first package 241, and the filter rod 22 is packaged by packages 242, 243, and 244. In addition, the entire aerosol generating product 2 may be packaged again by a single package 245. For example, when the filter rod 22 includes a plurality of segments, the plurality of segments may be packaged by packages 242, 243, and 244.

[0080] The first package 241 and the second package 242 may be formed of common filter wrapping paper. For example, the first package 241 and the second package 242 may be porous wrapping paper or non-porous wrapping paper. The first package 241 and the second package 242 may be formed of oil-resistant paper and / or aluminum laminated packaging material.

[0081] The third packaging member 243 may be formed of hard packaging paper. For example, the basis weight of the third packaging member 243 may be in the range of 88 g / m 2 Up to 96g / m 2 In the range of 90 g / m 2 Up to 94g / m 2 The thickness of the third package member 243 may be within the range of 120 μm to 130 μm, and preferably may be about 125 μm.

[0082] The fourth packaging member 244 can be formed of oil-resistant hard packaging paper. For example, the basis weight of the fourth packaging member 244 can be 88g / m 2 Up to 96g / m 2 In the range of 90 g / m 2 Up to 94g / m 2 The thickness of the fourth packaging member 244 may be in the range of 120 μm to 130 μm, and preferably may be about 125 μm.

[0083] The fifth package 245 may be formed of sterilization paper (e.g., MFW). Here, sterilization paper (MFW) may refer to a paper specially manufactured to be superior to ordinary paper in terms of tensile strength, water resistance, smoothness, etc. For example, the basis weight of the fifth package 245 may be 57 g / m 2 Up to 63g / m 2 In the range of 60g / m 2 The thickness of the fifth package member 245 may be in the range of 64 μm to 70 μm, and preferably may be about 67 μm.

[0084] A predetermined material may be added to the fifth package 245. The predetermined material is, for example, silicon. However, the embodiment is not limited thereto. For example, silicon may have properties such as heat resistance that is less affected by temperature, oxidation resistance that is not easily oxidized, tolerance to various chemicals, water resistance, or electrical insulation. However, silicon may not be used, and any material having the above-mentioned properties may be added (or coated) to the fifth package 245 without restriction.

[0085] The fifth package 245 can prevent the aerosol-generating product 2 from burning. For example, the aerosol-generating product 2 may burn when the tobacco rod 210 is heated by the heater 13. Specifically, when the temperature exceeds the ignition point of any one of the materials contained in the tobacco rod 310, the aerosol-generating product 2 may burn. Even in this case, since the fifth package 245 contains a non-combustible material, the aerosol-generating product 2 can be prevented from burning.

[0086] The fifth packaging member 245 can prevent the aerosol generating device 1 from being contaminated by substances generated in the aerosol generating product 2. When the user draws, liquid substances may be generated in the aerosol generating product 2. For example, as the aerosol generated by the aerosol generating product 2 is cooled by the external air, liquid substances (e.g., moisture, etc.) may be generated. By packaging the aerosol generating product 2 with the fifth packaging member 245, the liquid substances generated in the aerosol generating product 2 can be prevented from leaking to the outside of the aerosol generating product 2.

[0087] The tobacco rod 21 may include an aerosol-generating substance. For example, the aerosol-generating substance may include at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the embodiment is not limited thereto. The tobacco rod 21 may include other additives such as flavoring agents, wetting agents, and / or organic acids. The tobacco rod 21 may include a flavor liquid such as menthol or a humectant added by being sprayed onto the tobacco rod 21.

[0088] The tobacco rod 21 can be made into a variety of forms. For example, the tobacco rod 21 can be made into a sheet or a strand. The tobacco rod 21 can be made of shredded tobacco obtained by shredding tobacco sheets. The tobacco rod 21 can be wrapped with a heat-conductive material. For example, the heat-conductive material can be, for example, a metal foil, such as aluminum foil. However, the embodiment is not limited thereto. For example, the heat-conductive material wrapped around the tobacco rod 21 can evenly disperse the heat transferred to the tobacco rod 21, thereby increasing the thermal conductivity applied to the tobacco rod, thereby improving the taste of the cigarette. The heat-conductive material wrapped around the tobacco rod 21 can be used as a receptor heated by an induction heater. At this time, although not shown in the figure, the tobacco rod 21 can also include an additional receptor in addition to the heat-conductive material wrapped around the outside.

[0089] The filter rod 22 can be a cellulose acetate filter rod. However, the shape of the filter rod 22 is not limited. For example, the filter rod 22 can be a cylindrical rod, or a tubular rod with a hollow interior. The filter rod 22 can also be a groove-shaped rod. For example, when the filter rod 22 includes a plurality of segments, at least one of the segments can be made into other shapes.

[0090] The first section of the filter rod 22 may be a cellulose acetate filter. For example, the first section may be a tubular structure with a hollow interior. The first section may prevent the internal material of the tobacco rod 210 from being pushed back when the heater 13 is inserted into the tobacco 210 and may have an aerosol cooling effect. The diameter of the hollow portion in the first section may be in the range of 2 mm to 4.5 mm. However, the embodiment is not limited thereto.

[0091] The preferred length of the first section may be in the range of 4 mm to 30 mm. However, the embodiment is not limited thereto. Preferably, the length of the first section may be 10 mm. However, the embodiment is not limited thereto.

[0092] The hardness of the first segment can be adjusted by adjusting the content of the plasticizer during the manufacturing process of the first segment. The interior (eg, the hollow portion) of the first segment can be inserted with a structure such as a film or a tube of the same or different material.

[0093] The second section of the filter rod 22 cools the aerosol generated by the heater 13 heating the tobacco rod 21. Thus, the user can inhale the aerosol cooled to an appropriate temperature.

[0094] The length or diameter of the second segment may be determined according to the shape of the aerosol-generating article 2. For example, the preferred length of the second segment may be in the range of 7 mm to 20 mm. Preferably, the length of the second segment may be about 14 mm. However, the embodiment is not limited thereto.

[0095] The second section can be made by weaving polymer fibers. At this time, a scented liquid can be applied to the fibers made of polymer. The second section can be made by weaving together a single fiber to which a scented liquid is applied and a fiber made of polymer. The second section can be made of a curled polymer sheet.

[0096] The polymer may be made of a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum foil.

[0097] Since the second section is made of woven polymer fibers or curled polymer sheets, the second section may include a single channel or multiple channels extending in the longitudinal direction. Here, a channel refers to a path through which a gas (eg, air or aerosol) flows.

[0098] For example, the second segment made by crimping a polymer sheet can be made of a material having a thickness between about 5 μm and about 300 μm, such as between about 10 μm and about 250 μm. The total surface area of ​​the second segment can be about 300 mm 2 / mm to about 1000mm 2 / mm. The aerosol cooling element can be made of a specific surface area of ​​about 10mm 2 / mg to about 100mm 2 / mg of material.

[0099] In addition, the second segment may include a thread containing a volatile flavor component. The volatile flavor component may be menthol. However, the embodiment is not limited thereto. For example, the thread may be filled with a sufficient amount of menthol to provide at least 1.5 mg of menthol to the second segment.

[0100] The third section of the filter rod 22 can be a cellulose acetate filter rod. The preferred length of the third section can be in the range of 4 mm to 20 mm. For example, the length of the third section can be about 12 mm. However, the embodiment is not limited thereto.

[0101] The third section can be manufactured so that: when preparing the third section, a fragrance can be generated by spraying a fragrance liquid on the third section. A separate fiber with a fragrance liquid applied thereto can be inserted into the interior of the third section. The aerosol generated in the tobacco rod 21 can be cooled when passing through the second section of the filter rod 22, and the cooled aerosol can be delivered to the user through the third section. Therefore, when a fragrance element is added to the third section, the persistence of the fragrance delivered to the user can be improved.

[0102] The filter rod 22 may include at least one capsule 23. The capsule 23 may play a role in generating fragrance, or may play a role in generating aerosol. For example, the capsule 23 may have a structure in which a liquid of a fragrance agent is wrapped with a film. The capsule 23 may be spherical or cylindrical. However, the embodiment is not limited thereto.

[0103] Figure 5 FIG. 1 is a diagram showing an aerosol generating device according to an embodiment.

[0104] Reference Figure 5 The aerosol generating article 3 may further include a front end plug 33. The front end plug 33 may be arranged on the side of the tobacco rod 31 opposite to the filter rod 32. The front end plug 33 may prevent the tobacco rod 31 from being separated from the outside, and may also prevent the liquefied aerosol in the tobacco rod 31 from flowing into the interior of the aerosol generating device during smoking (for example, Figures 1 to 3 Aerosol generating device 1).

[0146] The controller 410 may control the temperature of the heater 450 by controlling the power supply from the battery 440 to the heater 450. For example, the controller 410 may control the power supply by controlling the switching of the switching element between the battery 440 and the heater 450. In another example, the direct heating circuit may control the power supply to the heater 450 according to the control command of the controller 410.

[0147] The controller 410 may analyze the sensing result of the sensing unit 420 and control the subsequent process.
