[0019] The singular expression includes the plural expression unless the context clearly dictates otherwise.

[0020] 1 and 2 are diagrams illustrating examples of aerosol products according to embodiments of the present disclosure.

[0021] Referring to FIG. 1, the aerosol product 2 includes a tobacco rod 21 and a filter rod 22 .

[0022] Although the filter rod 22 is shown in FIG. 1 as a single segment, this is not limiting. In other words, the filter rod 22 may be composed of multiple segments. For example, the filter rod 22 may include a segment that cools the aerosol and a segment that filters specific components contained in the aerosol. If necessary, the filter rod 22 may also include at least one segment that performs another function.

[0023] The diameter of the aerosol product 2 may be in the range of 5 mm to 9 mm, and the length may be about 48 mm, but is not limited thereto. For example, but not limited to, the length of the tobacco rod 21 may be about 12 mm, the length of the first segment of the filter rod 22 may be about 10 mm, the length of the second segment of the filter rod 22 may be about 14 mm, and the length of the third segment of the filter rod 22 may be about 12 mm.

[0024] The aerosol product 2 may be wrapped in at least one wrapper 24. The wrapper 24 may have at least one hole formed therein through which external air can enter or internal gas can escape. As an example, the aerosol product 2 may be wrapped in a single wrapper 24. As another example, the aerosol product 2 may be wrapped in two or more overlapping wrappers 24. For example, the tobacco rod 21 may be wrapped in a first wrapper 241, and the filter rod 22 may be wrapped in wrappers 242, 243, and 244. The entire aerosol product 2 may then be further wrapped in a single wrapper 245. If each filter rod 22 is composed of multiple segments, each segment may be wrapped in a wrapper 242, 243, or 244.

[0025] The first wrapper 241 and the second wrapper 242 may be made of a common filter wrapper. For example, the first wrapper 241 and the second wrapper 242 may be porous or non-porous. The first wrapper 241 and the second wrapper 242 may also be made of oil-resistant paper and / or aluminum laminate packaging material.

[0026] The third wrapper 243 may be made from hard wrapping paper. For example, the basis weight of the third wrapper 243 is 88 g / m 2 ~96g / m 2 and preferably 90 g / m 2 ~94g / m 2 The thickness of the third wrapper 243 may be in the range of 120 μm to 130 μm, and preferably 125 μm.

[0027] The fourth wrapper 244 may be made from a grease-resistant hard wrapper paper. For example, the basis weight of the fourth wrapper 244 is 88 g / m 2 ~96g / m 2 and preferably 90 g / m 2 ~94g / m 2The thickness of the fourth wrapper 244 may be in the range of 120 μm to 130 μm, and preferably 125 μm.

[0028] The fifth wrapper 245 may be made of a sterilized paper (MFW). The sterilized paper (MFW) may be specially manufactured to have improved tensile strength, water resistance, smoothness, etc. compared to general paper. For example, the basis weight of the fifth wrapper 245 is 57 g / m 2 ~63g / m 2 and preferably 60 g / m 2 The thickness of the fifth wrapper 245 may be in the range of 64 μm to 70 μm, and preferably 67 μm.

[0029] The fifth wrapper 245 may include a predetermined material. An example of the predetermined material may be, but is not limited to, silicon. For example, silicon may have properties such as heat resistance (i.e., small changes due to temperature), oxidation resistance (i.e., no oxidation), resistance to various chemicals, water repellency, and electrical insulation. However, any material other than silicon that has the above-mentioned properties may be applied (or coated) to the fifth wrapper 245 without limitation.

[0030] The fifth wrapper 245 can prevent the aerosol product 2 from burning. For example, when the tobacco rod 210 is heated by the heater 13, the aerosol product 2 may burn. Specifically, when the temperature of the tobacco rod 310 rises above the flash point of any one of the materials contained in the tobacco rod 310, the aerosol product 2 may burn. Even in such a case, the fifth wrapper 245 contains a non-flammable material, so it can prevent the aerosol product 2 from burning.

[0031] In addition, the fifth wrapper 245 can prevent the holder 1 from being contaminated by a substance generated in the aerosol product 2. A liquid substance can be generated in the aerosol product 2 when the user puffs. For example, a liquid substance (e.g., water) can be generated when the aerosol generated in the aerosol product 2 is cooled by external air. The fifth wrapper 245 wraps the aerosol product 2, thereby preventing the liquid substance generated in the aerosol product 2 from leaking out of the aerosol product 2.

[0032] The tobacco rod 21 may contain an aerosol-forming substance. For example, the aerosol-forming substance may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The tobacco rod 21 may also contain other additives, such as flavoring agents, humectants, and / or organic acids. A flavoring liquid, such as menthol or a humectant, may be added to the tobacco rod 21 by spraying it onto the tobacco rod 21.

[0033] The tobacco rod 21 can be manufactured in a variety of ways. For example, the tobacco rod 21 can be manufactured from a sheet or a strand. Alternatively, the tobacco rod 21 can be manufactured from finely chopped tobacco sheets. For example, the tobacco rod 21 can be surrounded by a thermally conductive material. The thermally conductive material can be, but is not limited to, a metal foil such as aluminum foil. For example, the thermally conductive material surrounding the tobacco rod 21 can uniformly distribute heat transferred to the tobacco rod 21, improving the thermal conductivity of the tobacco rod. This can improve the tobacco taste. The thermally conductive material surrounding the tobacco rod 21 can function as a susceptor heated by an induction heater. Although not shown in the drawings, the tobacco rod 21 can further include an additional susceptor in addition to the thermally conductive material surrounding the exterior.

[0034] The filter rod 22 may be a cellulose acetate filter. Meanwhile, the shape of the filter rod 22 is not limited. For example, the filter rod 22 may be a cylindrical rod or a tubular rod having a hollow interior. For example, the filter rod 22 may be a recessed rod. When the filter rod 22 is composed of multiple segments, at least one of the multiple segments may be manufactured in a different shape.

[0035] The first segment of the filter rod 22 may be a cellulose acetate filter. For example, the first segment may be a tubular structure having a hollow interior. The first segment prevents the inner material of the tobacco rod 210 from being pushed back when the heater 13 is inserted, and also provides a cooling effect for the aerosol. The diameter of the hollow interior of the first segment may be an appropriate diameter within the range of 2 mm to 4.5 mm, but is not limited thereto.

[0036] The length of the first segment can be an appropriate length within the range of 4 mm to 30 mm, but is not limited thereto. Preferably, the length of the first segment can be 10 mm, but is not limited thereto.

[0037] The hardness of the first segment can be adjusted by adjusting the content of plasticizer during manufacturing of the first segment. The first segment can also be manufactured by inserting a structure such as a film or tube made of the same or different material inside (e.g., hollow).

[0038] The second segment 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.

[0039] The length or diameter of the second segment can be determined in various ways depending on the form of the aerosol product 2. For example, the length of the second segment can be appropriately set within the range of 7 mm to 20 mm. Preferably, the length of the second segment can be about 14 mm, but is not limited to this.

[0040] The second segment can be made by weaving polymer fibers, in which case a flavor liquid can be applied to the polymer fibers, or by weaving the polymer fibers together with separate fibers that have been coated with a flavor liquid, or by forming the second segment from a crimped polymer sheet.

[0041] For example, the polymer may be made from 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.

[0042] The second segment may be formed from woven polymer fibers or a crimped polymer sheet, such that the second segment includes one or more longitudinally extending channels, where the channels may be passageways through which a gas (e.g., air or aerosol) may pass.

[0043] For example, the second segment of crimped polymer sheet may be formed from a material having a thickness between about 5 μm and about 300 μm, such as between about 10 μm and about 250 μm, and the total surface area of ​​the second segment may be less than about 300 mm 2 / mm and approximately 1000mm 2 / mm. The aerosol cooling element may have a specific surface area of ​​about 10 mm 2 / mg and about 100mm 2 It can be made from materials between 1 / mg.

[0044] Meanwhile, the second segment can include a thread containing a volatile flavor component, which can be, but is not limited to, menthol. For example, the thread can be loaded with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

[0045] The third segment of the filter rod 22 may be a cellulose acetate filter. The length of the third segment may be appropriately selected within a range of 4 mm to 20 mm. For example, the length of the third segment may be approximately 12 mm, but is not limited to this.

[0046] During the manufacturing process of the third segment, the third segment can be manufactured to emit a flavor by spraying a flavor liquid onto it. Alternatively, separate fibers coated with a flavor liquid can be inserted into the third segment. The aerosol generated in the tobacco rod 21 is cooled as it passes through the second segment of the filter rod 22, and the cooled aerosol is delivered to the user via the third segment. Therefore, when a flavor element is added to the third segment, the effect of improving the persistence of the flavor delivered to the user can be achieved.

[0047] The filter rod 22 may also include at least one capsule 23. The capsule 23 may function to generate a flavor or to generate an aerosol. For example, the capsule 23 may have a structure in which a liquid containing a flavoring agent is enclosed in a coating. The capsule 23 may have, but is not limited to, a spherical or cylindrical shape.

[0048] 2, the aerosol production product 3 may further include a front-end plug 33. The front-end plug 33 may be located on one side of the tobacco rod 31 facing the filter rod 32. The front-end plug 33 can prevent the tobacco rod 31 from detaching to the outside and can prevent aerosol liquefied from the tobacco rod 31 during smoking from flowing into the aerosol generation device 1 (FIGS. 4 to 6).

[0049] Filter rod 32 may include a first segment 321 and a second segment 322. Here, first segment 321 may correspond to the first segment of filter rod 22 of Figure 1. Second segment 322 may correspond to the third segment of filter rod 22 of Figure 1.

[0050] The diameter and overall length of the aerosol product article 3 may correspond to the diameter and overall length of the aerosol product article 2 of Figure 1. For example, but not limited to, the length of the front end plug 33 may be about 7 mm, the length of the tobacco rod 31 may be about 15 mm, the length of the first segment 321 may be about 12 mm, and the length of the second segment 322 may be about 14 mm.

[0051] The aerosol product 3 may be wrapped in at least one wrapper 35. The wrapper 35 may have at least one hole formed therein through which external air can enter or internal gas can escape. For example, the front end plug 33 may be wrapped in a first wrapper 351, the tobacco rod 31 may be wrapped in a second wrapper 352, the first segment 321 may be wrapped in a third wrapper 353, and the second segment 322 may be wrapped in a fourth wrapper 354. The entire aerosol product 3 may then be repackaged in a fifth wrapper 355.

[0052] In addition, at least one perforation 36 may be formed in the fifth wrapper 355. For example, but not limited to, the perforation 36 may be formed in the area surrounding the tobacco rod 31. The perforation 36 may serve to transfer heat generated by the heater 13 shown in Figures 5 and 6 to the interior of the tobacco rod 31.

[0053] The second segment 322 may also include at least one capsule 34. The capsule 34 may function to generate a flavor or to generate an aerosol. For example, the capsule 34 may have a structure in which a liquid containing a flavoring agent is enclosed in a coating. The capsule 34 may have, but is not limited to, a spherical or cylindrical shape.

[0054] The first wrapper 351 may be made by bonding a metal foil, such as aluminum foil, to a general filter wrapping paper. For example, the total thickness of the first wrapper 351 may be in the range of 45 μm to 55 μm, preferably 50.3 μm. The thickness of the metal foil of the first wrapper 351 may be in the range of 6 μm to 7 μm, preferably 6.3 μm. The basis weight of the first wrapper 351 may be 50 g / m 2 ~55g / m 2 and preferably 53 g / m 2 It could be.

[0055] The second wrapper 352 and the third wrapper 353 may be made of a common filter wrapper, for example, the second wrapper 352 and the third wrapper 353 may be a porous wrapper or a non-porous wrapper.

[0056] For example, the porosity of the second wrapper 352 may be, but is not limited to, 35000 CU. The thickness of the second wrapper 352 may be in the range of 70 μm to 80 μm, preferably 78 μm. The basis weight of the second wrapper 352 may be 20 g / m. 2 ~25g / m 2 and preferably 23.5 g / m 2 It could be.

[0057] For example, the porosity of the third wrapper 353 may be, but is not limited to, 24000 CU. The thickness of the third wrapper 353 may be in the range of 60 μm to 70 μm, preferably 68 μm. The basis weight of the third wrapper 353 is 20 g / m. 2 ~25g / m 2 and preferably 21 g / m 2 It could be.

[0058] The fourth wrapper 354 may be made of PLA laminated paper. Here, the PLA laminated paper may be a triple-ply paper including a paper layer, a PLA layer, and another paper layer. For example, the thickness of the fourth wrapper 354 may be in the range of 100 μm to 120 μm, preferably 110 μm. The basis weight of the fourth wrapper 354 may be 80 g / m 2 ~100g / m 2 and preferably 88 g / m 2 It could be.

[0059] The fifth wrapper 355 may be made of a sterilized paper (MFW). The sterilized paper (MFW) may be specially manufactured to have improved tensile strength, water resistance, smoothness, etc. compared to general paper. For example, the basis weight of the fifth wrapper 355 is 57 g / m 2 ~63g / m 2 and preferably 60 g / m 2The thickness of the fifth wrapper 355 may be in the range of 64 μm to 70 μm, and preferably 67 μm.

[0060] The fifth wrapper 355 may include a predetermined material. An example of the predetermined material may be, but is not limited to, silicon. For example, silicon has properties such as heat resistance (i.e., small changes due to temperature), oxidation resistance (i.e., no oxidation), resistance to various chemicals, water repellency, and electrical insulation. However, any material other than silicon that has the above-mentioned properties may be applied (or coated) to the fifth wrapper 355 without limitation.

[0061] The front-end plug 33 may be made of cellulose acetate. For example, the front-end plug 33 may be made by adding a plasticizer (e.g., triacetin) to cellulose acetate tow. The mono-denier of the filaments constituting the cellulose acetate tow may be in the range of 1.0 to 10.0, preferably in the range of 4.0 to 6.0. More preferably, the mono-denier of the filaments constituting the front-end plug 33 may be 5.0. The cross section of the filaments constituting the front-end plug 33 may be Y-shaped. The total denier of the front-end plug 33 may be in the range of 20,000 to 30,000, preferably in the range of 25,000 to 30,000. More preferably, the total denier of the front-end plug 33 may be 28,000.

[0062] Also, if desired, the front end plug 33 may include at least one channel, the cross section of which may be fabricated in a variety of shapes.

[0063] The tobacco rod 31 may correspond to the tobacco rod 21 described above with reference to Figure 1. Therefore, a detailed description of the tobacco rod 31 will be omitted below.

[0064] The first segment 321 may be made of cellulose acetate. For example, the first segment may be a hollow, tubular structure. The first segment 321 may be made of cellulose acetate to which a plasticizer (e.g., triacetin) is added. For example, the mono-denier and total denier of the first segment 321 may be the same as the mono-denier and total denier of the front end plug 33.

[0065] The second segment 322 may be made of cellulose acetate. The mono-denier of the filaments constituting the second segment 322 may be in the range of 1.0 to 10.0, preferably in the range of 8.0 to 10.0. More preferably, the mono-denier of the filaments of the second segment 322 may be 9.0. The cross section of the filaments of the second segment 322 may be Y-shaped.

[0066] FIG. 3 is a cross-sectional view of a medium portion according to one embodiment of the present disclosure.

[0067] 3, the tobacco rod 21 of the aerosol-producing article 2 may include an aerosol-generating portion 211 and a medium portion 212. The tobacco rod 21 may have a cylindrical shape.

[0068] The aerosol-generating section 211 may be located upstream of the medium section 212, but the location of the aerosol-generating section 211 is not limited thereto. Meanwhile, the aerosol-generating section 211 and the medium section 212 may be mixed in the tobacco rod 21 without being separated from each other.

[0069] For convenience, the following description will be based on the aerosol product 2 shown in FIG. 1, but the same features can be applied to the aerosol product 3 shown in FIG.

[0070] Here, "upstream" and "downstream" can be determined based on the direction of airflow that flows so that the generated aerosol is inhaled into the user's mouth or lungs when the user inhales using the aerosol-producing product. For example, in Figures 4 and 5, the aerosol generated by the tobacco rods 21 and 31 flows toward the filter rods 22 and 32, so the tobacco rods 21 and 31 are located upstream of the filter rods 22 and 32, and the filter rods 22 and 32 are located downstream of the tobacco rods 21 and 31. "Upstream" and "downstream" can be determined based on the relative positions of the components.

[0071] The aerosol generating unit 211 includes an aerosol generating material, which may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

[0072] The aerosol-generating material of the aerosol-generating unit 211 may be impregnated with a non-tobacco material. The non-tobacco material is a material that is not a tobacco material and may include paper or polylactic acid (PLA). The aerosol-generating material contained in the aerosol-generating unit 211 can increase the amount of atomization when the user smokes.

[0073] The medium portion 212 can include a medium. The medium can include a tobacco component 2121. The medium can include a non-tobacco material 2122 to which a liquid substance including the tobacco component 2121 is applied.

[0074] The liquid substance includes tobacco components 2121. For example, the tobacco components 2121 may be tobacco granules or tobacco fine particles. The tobacco components 2121 may be tobacco leaf pieces, tobacco stems, and / or tobacco fines generated during tobacco processing. The tobacco components 2121 may be regular (regular) tobacco granules or amorphous (irregular) tobacco granules. The tobacco components 2121 may be ground tobacco leaf, ground reconstituted tobacco, reconstituted tobacco leaf, etc.

[0075] The liquid substance may be applied to the non-tobacco material 2122 by a drop method, a tangential spray method, or a top spray or bottom spray method. Alternatively, the liquid substance may be applied to one side of the non-tobacco material 2122 using a slit nozzle. However, the method of applying the liquid substance to the non-tobacco material 2122 is not limited thereto.

[0076] The thickness of the applied liquid substance may affect the amount of nicotine transferred during smoking and may affect the ease of loading the non-tobacco material 2122. The thickness of the applied liquid substance is preferably less than the thickness of the sheet of non-tobacco material 2122, but is not limited to this.

[0077] The liquid substance further includes a binder. The liquid substance may include a liquid mixture of the tobacco component 2121 and a binder.

[0078] The liquid material can be adsorbed to the non-tobacco material 2122 by a binder. The non-tobacco material 2122 is a material that is not a tobacco material and can include paper (cellulose fibers) or polylactic acid (PLA) tow. The non-tobacco material 2122 can be processed by conventional processes, including mechanical pulping, refining, chemical pulping, bleaching, sulfate pulping, and combinations thereof.

[0079] The binder can be a liquid binder, and an appropriate amount of the liquid binder can be mixed with the tobacco component 2121 to provide a liquid material with an appropriate viscosity that can be applied to the non-tobacco material 2122. By spraying the liquid material onto the non-tobacco material 2122, the overall particle size of the medium can be adjusted and the surface properties of the medium can be improved.

[0080] The liquid binder includes water, alcohol, and starch. The liquid binder can be prepared by mixing starch with water and alcohol. The liquid binder can further include gums. The liquid binder allows the tobacco granules or fine particles contained in the liquid material to be uniformly dispersed throughout the non-tobacco material.

[0081] The ratio of starch in the liquid binder can be adjusted, for example, the liquid binder can contain 25 to 35% by weight of starch.

[0082] The higher the starch content in the liquid binder, the better the tobacco material will adhere to the non-tobacco material 2122. On the other hand, if the starch content falls below a certain level, the tobacco material may not be able to properly adhere to the non-tobacco material 2122.

[0083] Tables 1 and 2 below show the dropout rate, nicotine amount, glycerin amount, and equipment operating rate depending on the content ratio of water, alcohol, starch, and gums contained in a liquid binder according to one embodiment of the present disclosure.

[0084] [Table 1]

[0085] [Table 2]

[0086] Table 1 shows the content ratio of water, alcohol and starch, and Table 1 shows the content ratio of water, alcohol and starch.

[0087] Table 1 shows the content ratios of water, alcohol, starch, and gums contained in the liquid binder. In Table 1, the ratios of water, alcohol, starch, and gums are based on weight (wt%).

[0088] In Table 2, "detachment rate" indicates the ratio of tobacco components detached during the aerosol product manufacturing process, which involves cutting and bonding non-tobacco materials coated with a liquid substance containing tobacco components, based on the non-tobacco material before processing. In Table 2, "nicotine" indicates the amount of nicotine (mg) generated per aerosol product (1 cigarette) manufactured. In Table 2, "Gly" indicates the amount of glycerin (mg) generated per aerosol product (1 cigarette) manufactured. In Table 2, "equipment utilization rate" indicates the number of aerosol product rods that can be produced per minute by the equipment that manufactures the aerosol product.

[0089] Referring to Tables 1 and 2, as the starch content in the liquid binder increases from 25% to 40% (sections #1 to #3 in Table 1), the dropout rate decreases from 13.8% to 8.7%, the nicotine content decreases from 0.63 mg / cig to 0.53 mg / cig, and the equipment operating rate decreases from 400 RPM_rod / min to 200 RPM_rod / min.

[0090] The liquid binder according to one embodiment of the present disclosure contains starch, which allows the tobacco components contained in the liquid material to be effectively adsorbed onto non-tobacco materials. This reduces the rate of detachment during the manufacturing process of the aerosol product. However, as the starch content in the liquid binder increases, the rate of detachment improves, but the equipment utilization rate tends to decrease. Therefore, it is necessary to adjust the starch content in the liquid binder to an appropriate range.

[0091] [Table 3]

[0092] [Table 4]

[0093] Tables 3 and 4 show the dropout rate, nicotine content, glycerin content, and equipment utilization rate according to the change in the starch content ratio contained in the liquid binder according to one embodiment of the present disclosure. In Table 5, the water and alcohol content ratios are 45% by weight and 15% by weight, respectively.

[0094] Referring to Tables 3 and 4, the higher the content of starch in the liquid binder, the higher the separation rate and the equipment operating rate.

[0095] Comparing sections #4 and #5, when the starch content increased from 35% by weight to 39% by weight, the dropout rate decreased (8.6% to 8.3%), and the equipment operating rate decreased significantly (250 RPM_rod / min to 130 RPM_rod / min) compared to the change in starch content. Therefore, considering the tendency for equipment operating rate to decrease, it is found that the starch content is preferably about 35% or less.

[0096] Comparing sections #6 and #7, when the starch content was reduced from 30% by weight to 20% by weight, the dropout rate increased significantly (from 8.3% to 12.5%) compared to the change in starch content, and the equipment operating rate also increased (from 320 RPM_rod / min to 440 RPM_rod / min). Therefore, considering the tendency for the dropout rate to decrease, it is preferable that the starch content be about 25% or more.

[0097] The ratio of starch, water, and alcohol in the liquid binder can be adjusted. For example, the liquid binder can contain 25 to 35% by weight of starch, 40 to 50% by weight of water, and 10 to 20% by weight of alcohol. The liquid binder can further contain 5 to 15% by weight of gums.

[0098] [Table 5]

[0099] [Table 6]

[0100] Tables 5 and 6 show the dropout rate, nicotine content, glycerin content, and equipment utilization rate for different ratios of water and alcohol contained in the liquid binder according to one embodiment of the present disclosure. In Table 5, the starch and gum content ratios are 35% by weight and 5% by weight, respectively. The data for categories #2 and #5 are the same as those for categories #2 and #5 listed in Tables 1 to 4.

[0101] Referring to Tables 5 and 6, as the water content in the liquid binder decreases and the alcohol content increases, the separation rate decreases and the equipment operating rate increases.

[0102] Comparing sections #5 and #2, when the water content increases from 45 wt% to 55 wt% and the alcohol content decreases from 15 wt% to 5 wt%, the separation rate increases significantly (from 8.6% to 11.6%), while the equipment operating rate remains unchanged (250 RPM_rod / min). Therefore, considering the effect of the deterioration of the separation rate, it is preferable that the water content be approximately 50 wt% or less and the alcohol content be approximately 10 wt% or more.

[0103] Comparing sections #8 and #9, when the water content is reduced from 40 wt% to 35 wt% and the alcohol content is increased from 20 wt% to 25 wt%, the separation rate is significantly reduced (from 8.5% to 7.7%), while the equipment operating rate remains unchanged (300 RPM_rod / min). Therefore, considering the effect of the deterioration of the separation rate, it is preferable that the water content be approximately 40 wt% or more and the alcohol content be approximately 20 wt% or less.

[0104] The liquid binder according to the embodiment of the present disclosure may contain 25-35% by weight of starch, 40-50% by weight of water, and 10-20% by weight of alcohol. In this case, during the process of manufacturing an aerosol product, the dropout rate can be reduced to about 9% or less, and the equipment operating rate can be maintained at about 250 RPM_rod / min or more.

[0105] The liquid binder may further include at least one of hydroxypropyl methylcellulose, pullulan, and carboxymethyl cellulose.

[0106] The medium portion 212 may further include an additive, which may be at least one of a pH adjuster, a flavoring agent, an organic acid, and the like.

[0107] The pH adjuster can be added during the production of tobacco granules or reconstituted tobacco leaves. Alternatively, the medium can be added in a manner that includes granules composed of the pH adjuster. The pH adjuster can be at least one of calcium carbonate, sodium bicarbonate, calcium oxide, etc. The pH adjuster can adjust the pH of the medium to alkaline, thereby facilitating the release of flavor components from the medium.

[0108] Flavoring agents may include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, salsa, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, ylang ylang, sage, spearmint, ginger, coriander, coffee, and the like.

[0109] 4 to 6 are diagrams showing examples in which the aerosol product 2 is inserted into the aerosol generation device.

[0110] Referring to Fig. 4, the aerosol generating device 1 includes a battery 11, a control unit 12, and a heater 13. Referring to Figs. 5 and 6, the aerosol generating device 1 further includes a vaporizer 14. An aerosol product 2 can be inserted into the internal space of the aerosol generating device 1.

[0111] 4 to 6 show the components of the aerosol generation device 1 according to this embodiment. However, it would be understandable to a person having ordinary skill in the technical field of this embodiment that the aerosol generation device 1 may further include general-purpose components in addition to the components shown in FIGS.

[0112] 5 and 6 show the aerosol generating device 1 including the heater 13, but the heater 13 can be omitted if necessary.

[0113] In Fig. 4, the battery 11, the control unit 12, and the heater 13 are arranged in a row. In Fig. 5, the battery 11, the control unit 12, the vaporizer 14, and the heater 13 are arranged in a row. In Fig. 6, the vaporizer 14 and the heater 13 are arranged in parallel. However, the internal structure of the aerosol generation device 1 is not limited to those shown in Figs. 4 to 6. In other words, the arrangement of the battery 11, the control unit 12, the heater 13, and the vaporizer 14 can be changed depending on the design of the aerosol generation device 1.

[0114] When the aerosol production product 2 is inserted into the aerosol generation device 1, the aerosol generation device 1 can generate an aerosol by activating the heater 13 and / or the vaporizer 14. The aerosol generated by the heater 13 and / or the vaporizer 14 passes through the aerosol production product 2 and is delivered to the user.

[0115] If necessary, the aerosol generating device 1 can heat the heater 13 even when the aerosol product 2 is not inserted in the aerosol generating device 1 .

[0116] The battery 11 supplies power used to operate the aerosol generation device 1. For example, the battery 11 can supply power to heat the heater 13 or the vaporizer 14, and can supply power necessary for the operation of the control unit 12. The battery 11 can also supply power necessary for the operation of a display, a sensor, a motor, etc. provided in the aerosol generation device 1.

[0117] The control unit 12 controls the overall operation of the aerosol generation device 1. Specifically, the control unit 12 controls the operation of not only the battery 11, the heater 13, and the vaporizer 14, but also other components included in the aerosol generation device 1. The control unit 12 can also check the status of each component of the aerosol generation device 1 and determine whether the aerosol generation device 1 is in an operable state.

[0118] The control unit 12 includes 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 storing a program executable by the microprocessor. Those skilled in the art will understand that the processor may also be implemented as other types of hardware.

[0119] The heater 13 can be heated by power supplied from the battery 11. For example, when a cigarette is inserted into the aerosol generating device 1, the heater 13 can be located outside the cigarette. Thus, the heated heater 13 can increase the temperature of the aerosol generating material inside the cigarette.

[0120] The heater 13 may be an electric resistance heater. For example, the heater 13 may include an electrically conductive track, and the heater 13 may be heated by passing an electric current through the electrically conductive track. However, the heater 13 is not limited to the above example, and any heater that can heat up to a desired temperature may be used. Here, the desired temperature may be pre-set in the aerosol generating device 1, or may be set by the user.

[0121] Meanwhile, as another example, the heater 13 may be an induction heater. Specifically, the heater 13 may include an electrically conductive coil for heating the cigarette by induction heating, and the cigarette may include a susceptor that can be heated by the induction heater.

[0122] For example, the heater 13 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 inside or outside of the aerosol product article 2 may be heated.

[0123] Furthermore, a plurality of heaters 13 may be disposed in the aerosol generating device 1. Here, the plurality of heaters 13 may be inserted inside the aerosol product 2 or may be disposed outside the aerosol product 2. Furthermore, some of the plurality of heaters 13 may be inserted inside the aerosol product 2, and the rest may be disposed outside the aerosol product 2. Furthermore, the shape of the heaters 13 is not limited to the shapes shown in FIGS. 4 to 6, and various shapes may be manufactured.

[0124] The vaporizer 14 can heat the liquid composition to generate an aerosol, and the generated aerosol can be transmitted to a user through the aerosol-producing article 2. In other words, the aerosol generated by the vaporizer 14 can travel along an airflow passage of the aerosol-generating device 1, and the airflow passage can be configured to allow the aerosol generated by the vaporizer 14 to be transmitted to a user through the cigarette.

[0125] For example, the vaporizer 14 may include, but is not limited to, a liquid reservoir, a liquid transfer means, and a heating element. For example, the liquid reservoir, the liquid transfer means, and the heating element may be independent modules and included in the aerosol generation device 1.

[0126] The liquid reservoir can store a liquid composition. For example, the liquid composition can be a liquid containing tobacco-containing substances, including volatile tobacco flavor components, or a liquid containing non-tobacco substances. The liquid reservoir can be detachably mounted on the vaporizer 14 or can be integrally mounted on the vaporizer 14.

[0127] For example, the liquid composition may contain water, solvent, ethanol, plant extract, fragrance, flavoring, or vitamin mixture. Flavoring may include, but is not limited to, menthol, peppermint, spearmint oil, various fruit flavoring ingredients, etc. Flavoring may include ingredients that can provide various flavors or flavors to the user. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid composition may also contain an aerosol-forming agent such as glycerin and propylene glycol.

[0128] The liquid transfer means can transfer the liquid composition in the liquid reservoir to the heating element, for example, but not limited to, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0129] The heating element is an element for heating the liquid composition delivered by the liquid delivery means. For example, the heating element may be, but is not limited to, a metal hot wire, a metal hot plate, a ceramic heater, etc. The heating element may also be made of a conductive filament such as nichrome wire and may be arranged in a structure wound around the liquid delivery means. The heating element can be heated by supplying an electric current and transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol can be generated.

[0130] For example, the vaporizer 14 may be referred to as, but is not limited to, a cartomizer or an atomizer.

[0131] Meanwhile, the aerosol generating device 1 may further include general-purpose components in addition to the battery 11, the control unit 12, the heater 13, and the vaporizer 14. For example, the aerosol generating device 1 may include a display capable of outputting visual information and / or a motor for outputting tactile information. The aerosol generating device 1 may also include at least one sensor (such as a puff detection sensor, a temperature detection sensor, or a cigarette insertion detection sensor). The aerosol generating device 1 may also be manufactured to have a structure that allows external air to flow in or internal gas to flow out even when the aerosol product 2 is inserted.

[0132] Although not shown in Figures 4 to 6, the aerosol generation device 1 can also be used to configure a system together with a separate cradle. For example, the cradle can be used to charge the battery 11 of the aerosol generation device 1. Alternatively, the heater 13 can be heated while the cradle and the aerosol generation device 1 are combined.

[0133] As described above, according to at least one of the embodiments of the present disclosure, when processing non-tobacco material products containing tobacco granules, the rate of tobacco granules falling off during cutting can be reduced, thereby improving the quality of the aerosol product.

[0134] According to at least one embodiment of the present disclosure, when processing non-tobacco material products containing tobacco granules, the rate of tobacco granules falling off during cutting can be reduced, thereby reducing the cost of the aerosol product.

[0135] According to at least one of the embodiments of the present disclosure, when producing aerosol products, it is possible to prevent a decrease in the production efficiency of aerosol products by preventing the equipment utilization rate from falling below a certain level.

[0136] Referring to Figures 1 to 6, an aerosol product 2 according to one aspect of the present disclosure includes an aerosol-generating rod 21 including a non-tobacco material 2122 to which a liquid substance is applied, the liquid substance including tobacco components 2121 and a liquid binder, the liquid binder including water, alcohol, and starch.
