Description

[Technical Field]

[0001] The present disclosure relates to aerosol products and aerosol generating devices. [Background technology]

[0002] Generally, tobacco refers to a perennial plant of the Solanaceae family in the order Dicotyledonous plants, but nowadays it is commonly referred to as a product made for smoking by wrapping tobacco leaves in cigarette paper with a filter on one side. There are thousands of varieties of such cigarettes sold around the world in various shapes and forms.

[0003] Among these, in the case of combustible tobacco products, such as cigarettes, cigars, and pipe tobacco, which are lit and smoked, the smoke contains not only aerosols containing nicotine, but also many other components such as tar, nitroamines, hydrocarbons, and carbon monoxide.

[0004] As an alternative to these shortcomings of combustion-not-burn cigarettes, methods of generating aerosol by heating the aerosol-producing material within cigarettes, rather than by burning cigarettes, have become widely used and are seeing increasing demand, leading to active research into heated cigarettes or heated aerosol generators.

[0005] Specifically, the aerosol generator has a similar form to a conventional combustion-not-burn cigarette, and generates mainstream smoke containing aerosol by heating the aerosol product quality in the heated cigarette using a heater or ultrasonic vibration, etc., which has the advantage of minimizing the emission of components such as tar while satisfying the smoker's desire to smoke, and is therefore creating a new market as an alternative to conventional combustion-not-burn cigarettes.

[0006] However, heated cigarettes generated by aerosol generators generate high-temperature mainstream smoke inside, and this high-temperature aerosol may be transmitted to the user, causing inconvenience to the user and potentially causing burns. Summary of the Invention [Problem to be solved by the invention]

[0007] In order to solve the above problems, the object of the present disclosure is to provide an aerosol product that can prevent users from experiencing inconvenience or being burned.

[0008] Another object of the present disclosure is to provide an aerosol product that can cool hot mainstream smoke without reducing atomization. [Means for solving the problem]

[0009] According to one embodiment, an aerosol product can be provided, which includes a tobacco medium portion, a filter portion spaced apart from the tobacco medium portion, and a tubular cooling portion disposed between the tobacco medium portion and the filter portion, wherein a cooling agent is contained within a body constituting the cooling portion. [Effects of the Invention]

[0010] As described above, the aerosol product according to one aspect of the present disclosure can prevent users from experiencing discomfort or being burned by high-temperature mainstream smoke.

[0011] Moreover, the high-temperature mainstream smoke can be effectively cooled without reducing the amount of atomization. [Brief explanation of the drawings]

[0012] In order that the contents of the present disclosure may be understood by those skilled in the art, a more detailed description may be provided by reference to the form of some exemplary embodiments, some of which are illustrated in the accompanying drawings.

Furthermore, it will be understood that the aspects and advantages of the present disclosure can be achieved by the embodiments described in the claims and combinations thereof.

[0031] Since the present disclosure can be modified in various ways and can have various embodiments, specific embodiments will be illustrated and described in detail in the detailed description, but this is not intended to limit the disclosure to the specific embodiments, and it should be understood that the present disclosure includes all modifications, equivalents, and alternatives that fall within the spirit and technical scope of the present disclosure.

[0032] The terms used in this disclosure are merely for the purpose of describing particular embodiments and are not intended to limit the present disclosure. The singular expressions include the plural expressions unless the context clearly dictates otherwise. In this disclosure, the terms "comprise" or "have" are intended to specify the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and should be understood not to preclude the presence or possible addition of one or more other features, numbers, steps, operations, components, and parts, or combinations thereof.

[0033] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Note that in the accompanying drawings, identical components are represented by the same reference numerals whenever possible. Also, detailed descriptions of known functions and configurations that would obscure the gist of the present disclosure will be omitted. For the same reasons, some components in the accompanying drawings may be exaggerated, omitted, or shown schematically.

[0034] The following describes an aerosol product according to one embodiment of the present disclosure.

[0035] Figure 1 is a schematic exploded perspective view of an aerosol product according to one embodiment of the present disclosure, Figure 2 is a schematic perspective view of an aerosol product according to one embodiment of the present disclosure, Figure 3 is an enlarged view of the inside of region A in Figure 2, and Figure 4 is a cross-sectional view of an aerosol product according to one embodiment of the present disclosure.

[0036] 1 to 4, an aerosol product 100 according to one embodiment of the present disclosure includes a tobacco medium portion 110, a cooling portion 130, a filter portion 150, and a wrapper 170. It will be understood by those skilled in the art that the aerosol product 100 may further include other general components in addition to the components shown in FIGS.

[0037] The aerosol production product 100 according to this embodiment may be inserted into an aerosol generating device 300 (see FIG. 19 ) described below and heated. When the aerosol production product 100 is heated, mainstream smoke is delivered to the user. The mainstream smoke is an airflow flowing from upstream to downstream inside the aerosol production product 100. Here, upstream refers to the tobacco medium portion 110 side, and downstream refers to the filter portion 150 side. A user of the aerosol production product 100 can inhale the mainstream smoke through the downstream end of the aerosol production product 100.

[0038] The aerosol production article 100 may be formed in a cylindrical shape, with a diameter of 4.7 mm to 9.9 mm. The tobacco medium portion 110, the cooling portion 130, and the filter portion 150 may also be cylindrical with a diameter of 4.7 mm to 9.9 mm.

[0039] Additionally, the aerosol-producing article 100 may have a length between 31 mm and 60 mm. The tobacco medium portion 110 may have a length between 17 mm and 30 mm. The cooling portion 130 may have a length between 4 mm and 10 mm, and the filter portion 150 may have a length between 10 mm and 20 mm.

[0040] The values for the shape, diameter, and length of the aerosol product 100 and its components are shown as examples, but are not necessarily limited thereto. The shape and values of the aerosol product 100 may be modified within the scope of those skilled in the art.

[0041] The tobacco medium portion 110 is located upstream of the aerosol-producing product 100 and contains a tobacco medium that generates an aerosol. The tobacco medium of the tobacco medium portion 110 contains nicotine, which allows mainstream smokers to experience the taste and aroma characteristic of cigarettes.

[0042] When the aerosol product 100 according to this embodiment is heated by the aerosol generating device 300 described later, and the aerosol generated from the aerosol generating device 300 flows into the aerosol product 100, nicotine is adsorbed onto the surface of the aerosol as it passes through the tobacco medium portion 110 and is delivered to the user.

[0043] In this case, the nicotine contained in the tobacco medium may be one or more of freebase nicotine and nicotine salt, and the nicotine may be naturally occurring nicotine or synthetic nicotine.

[0044] Nicotine salts are formed by adding a suitable acid, including an organic acid or an inorganic acid, to nicotine. The acid for forming the nicotine salt is appropriately selected taking into consideration the blood nicotine absorption rate, the heating temperature of the heater, the flavor or taste, solubility, etc. For example, the acid for forming the nicotine salt may be, but is not limited to, a single acid selected from the group consisting of benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharinic acid, malonic acid, or malic acid, or a mixture of two or more acids selected from the group.

[0045] Meanwhile, the tobacco medium of the tobacco medium portion 110 can be manufactured in various forms. For example, the tobacco medium may be manufactured in a sheet or a strand. Alternatively, the tobacco medium may be manufactured in the form of shredded tobacco obtained by cutting a tobacco sheet. Alternatively, the tobacco medium may be manufactured in the form of granules containing tobacco.

[0046] The tobacco medium portion 110 may be formed in a cylindrical shape. However, the shape of the tobacco medium portion 110 is not necessarily limited to this, and the tobacco medium portion 110 may be configured in a bar shape having a cross section of various shapes.

[0047] Here, the tobacco medium portion 110 may be manufactured by folding a tobacco sheet into a cylindrical shape, or by molding tobacco strands, tobacco shreds, or tobacco granules into a cylindrical shape.

[0048] When the tobacco medium portion 110 is made of a plurality of tobacco strands obtained by cutting a tobacco sheet into small pieces, the tobacco medium portion 110 may be formed by combining the plurality of tobacco strands in the same direction (e.g., parallel to each other) or randomly. Specifically, the tobacco medium portion 110 may be formed by combining the plurality of tobacco strands to form a plurality of longitudinal channels through which the aerosol can pass. Here, the longitudinal channels may be uniform or non-uniform depending on the size and arrangement of the tobacco strands.

[0049] The tobacco medium portion 110 may further include an aerosol-producing quality to increase the amount of atomization. For example, the aerosol-producing quality 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.

[0050] The tobacco medium portion 110 may further include a flavoring substance to add flavor to the aerosol. For example, the tobacco medium portion 110 may include other additives such as flavoring agents, humectants, and / or organic acids. The tobacco medium portion 110 may also be doped with a flavoring liquid such as menthol or a humectant by spraying it onto the tobacco medium portion 110.

[0051] In this case, the flavoring agent may include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander, or coffee. The humectant may include glycerin or propylene glycol. However, the flavoring agent is not limited to these and may include a variety of other materials.

[0052] The tobacco medium portion 110 may be wrapped in a thermally conductive material. The thermally conductive material evenly distributes heat transferred to the tobacco medium portion 110, improving the thermal conductivity of the tobacco medium portion 110 and thereby improving the taste of the tobacco. The thermally conductive material may be a metal foil, for example, aluminum. However, the thermally conductive material is not necessarily limited to this, and various metal foils used as thermally conductive materials may be used.

[0053] Meanwhile, in this embodiment, the tobacco medium portion 110 is made up of at least one segment. For example, the tobacco medium portion 110 may be made up of one segment, two segments, or three segments. Specifically, the tobacco medium portion 110 according to this embodiment shown in Figure 4 is made up of one segment. Alternatively, as shown in Figures 5 and 6, the tobacco medium portion 110 may be made up of two segments. Alternatively, as shown in Figure 7, the tobacco medium portion 110 may be made up of three segments.

[0054] 4, the tobacco medium portion 110 of this embodiment consists of one segment. The segment of the tobacco medium portion 110 is filled with a tobacco medium. That is, in this embodiment, the tobacco medium portion 110 consists of one segment filled with a tobacco medium.

[0055] Here, the segments may be manufactured by folding a tobacco sheet into a cylindrical shape as described above, or by molding tobacco strands, shredded tobacco, or granulated tobacco into a cylindrical shape. The segments may further contain aerosol-producing qualities and / or flavoring substances that can increase the atomization amount.

[0056] Furthermore, the segment of the tobacco medium portion 110 may be heated by being coupled to a heating portion 370 (see FIG. 19) of the aerosol generating device 300 that heats the aerosol product 100. In FIG. 19, the heating portion 370 is illustrated as being disposed around the aerosol product 100, but this is not limiting, and the heating portion may also be inserted inside the tobacco medium portion 110 to heat the tobacco medium portion 110.

[0057] The tobacco medium portion 110 may further include a structure for identifying the aerosol product 100. The aerosol product 100 may have a variety of flavors and aromas, and may include a structure (not shown) for identifying such a variety of aerosol product 100 from one another. For example, the tobacco medium portion 110 may include a metal foil that changes the inductance of an aerosol product recognition coil included in the aerosol generating device 300. Here, the metal foil is disposed on the outer circumferential surface of the tobacco medium portion 110.

[0058] 5 and 6, the tobacco medium portion 110 is made up of two segments, one of which contains the tobacco medium and the other of which does not contain the tobacco medium.

[0059] Referring to Figure 5, tobacco medium portion 110 includes a first segment 111 and a second segment 119. First segment 111 is a segment filled with tobacco medium and may be identical to the segment of tobacco medium portion 110 of Figure 4 described above.

[0060] The second segment 119 is located at the upstream end of the aerosol production product 100 and prevents the first segment 111 containing the tobacco medium from escaping to the outside. That is, the tobacco medium portion 110 of this modified example may be arranged in the order of the second segment 119 and the first segment 111 from the upstream side.

[0061] The second segment 119 prevents impurities from flowing into the first segment 111 from the outside, and can prevent aerosol liquefied during smoking from flowing into the aerosol generation device 300 (see FIG. 19).

[0062] Additionally, when the aerosol production article 100 is inserted into the aerosol generation device 300 , the second segment 119 supports the aerosol production article 100 so that the aerosol production article 100 is fixed to the aerosol generation device 300 .

[0063] The second segment 119 may be a cellulose acetate filter. For example, the second segment 119 may be made of cellulose acetate tow with a plasticizer such as triacetin added. The cellulose acetate tow may also contain aerosol-producing qualities.

[0064] The aerosol product quality included in second segment 119 may exclude nicotine. For example, second segment 119 may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the aerosol product quality included in second segment 119 is not necessarily limited thereto. For example, second segment 119 may include a material in which glycerin and propylene glycol are mixed in a ratio of approximately 8:2. However, the above-mentioned ratio is not limiting.

[0065] In addition, other additives such as flavoring agents, humectants, and / or organic acids may be included in the second segment 119. However, the material and type of the second segment 119 are not necessarily limited thereto and may be changed within the scope of those skilled in the art.

[0066] The second segment 119 may have a through hole formed therein through which an aerosol flows from the outside to form mainstream smoke inside the aerosol production product 100. The through hole formed in the second segment 119 has a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto, and various cross-sectional shapes may be used.

[0067] On the other hand, if the second segment 119 comprises a crimped sheet impregnated with an aerosol-producing material, the second segment 119 may not be perforated.

[0068] When a portion of the aerosol product 100 is inserted into the aerosol generating device 300, the aerosol generated in the aerosol generating device 300 flows into the aerosol product 100 through the second segment 119, and the aerosol forms mainstream smoke inside the aerosol product 100 and can be delivered to a user. Also, the aerosol generated inside the second segment 119 including the aerosol product can form mainstream smoke and be delivered to a user.

[0069] The second segment 119 may further include a structure for identifying the aerosol product 100. The aerosol product 100 may be available in a variety of flavors and scents, and the second segment 119 may include a structure for distinguishing such various types of aerosol product 100 from one another. For example, the second segment 119 may include a metal foil that changes the inductance of an aerosol product recognition coil included in the aerosol generating device 300. However, the present invention is not limited to this, and the structure for identifying the aerosol product 100 may be included in the first segment 111 as well as the second segment 119.

[0070] Referring to FIG. 6, the tobacco medium portion 110 includes a first segment 111 and a second segment 117 .

[0071] The first segment 111 is located at the upstream end, and is a segment filled with a tobacco medium, and may be made of the same material as the first segment 111 of FIG. 5 described above.

[0072] The second segment 117 can prevent the tobacco medium in the first segment 111 from escaping to the cooling section 130, which will be described later. For example, when a heating section for heating the aerosol product 100 is inserted into the first segment 111, the tobacco medium in the first segment 111 may detach and move toward the cooling section 130. By disposing the second segment 117 between the first segment 111 and the cooling section 130, the tobacco medium in the first segment 111 can be prevented from escaping toward the cooling section 130.

[0073] The second segment 117 may be made of the same material as the second segment 119 shown in FIG. 5 above.

[0074] In addition, the second segment 117 may have a through hole formed in the first segment 111 or penetrating the first segment 111 to allow the aerosol to flow in. The through hole formed in the second segment 117 has a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto, and various cross-sectional shapes may be used.

[0075] In this way, the first segment 111 and the second segment 117 of the tobacco medium portion 110 may each be made of the same material as the first segment 111 and the second segment 119 of the tobacco medium portion 110 in Fig. 5 described above. However, the first segment 111 and the second segment 117 of the tobacco medium portion 110 may be arranged in a different order from the first segment 111 and the second segment 119 in Fig. 5. In other words, the tobacco medium portion 110 of this modified example may be arranged in the order of the first segment 111 and the second segment 117 from the upstream side.

[0076] On the other hand, in the modified example shown in Figure 7, the tobacco medium portion 110 is made up of three segments, at least one of which may contain a tobacco medium.

[0077] 7, the tobacco medium portion 110 includes a first segment 111, a second segment 113, and a third segment 115. In this modification, the first segment 111 including the tobacco medium is disposed in the center, and the second segment 113, the first segment 111, and the third segment 115 are disposed in this order from the upstream side.

[0078] The first segment 111 is located in the center of the three segments of the tobacco medium portion 110, and is a segment filled with a tobacco medium, and may be made of the same material as the first segment 111 in FIG. 5 described above.

[0079] The second segment 113 and the third segment 115 are arranged on either side of the first segment 111, and may be made of the same material as the second segment 119 of FIG.

[0080] The second segment 113 prevents impurities from flowing into the first segment 111 from the outside and prevents aerosol liquefied during smoking from flowing into the aerosol generation device 300. In addition, the second segment 113 may have the same structure, function, and material as the second segment 119 of FIG. 5 described above.

[0081] The third segment 115 can prevent the tobacco medium of the first segment 111 from escaping into the cooling section 130. In addition, the third segment 115 may have the same structure, function and material as the second segment 117 of FIG.

[0082] In this manner, in this modification, the tobacco medium portion 110 can be configured by arranging the second segment 113 and the third segment 115 on either side of the first segment 111 containing the tobacco medium.

[0083] 1 to 4 again, in this embodiment, the filter unit 150 is located at the downstream end, spaced apart from the tobacco medium unit 110. The filter unit 150 can filter at least one substance contained in mainstream smoke.

[0084] The filter unit 150 may be a cellulose acetate filter, and may be made by adding a plasticizer such as triacetin to cellulose acetate tow. However, the material and type of the filter unit 150 are not limited thereto and may be changed within the scope of those skilled in the art.

[0085] The filter portion 150 may be cylindrical. However, the shape of the filter portion 150 is not necessarily limited to this, and may have various shapes corresponding to the shape of the tobacco medium portion 110.

[0086] The filter unit 150 may be manufactured to emit a flavor. For example, a flavoring liquid may be sprayed onto the filter unit 150, or a separate fiber onto which the flavoring liquid is applied may be included inside the filter unit 150.

[0087] Alternatively, the filter unit 150 may include at least one capsule (not shown). The capsule may generate a flavor or an aerosol. For example, the capsule may have a structure in which a liquid containing a flavoring agent is enclosed in a film. Here, the capsule may have a spherical or cylindrical shape, but the shape of the capsule is not necessarily limited thereto.

[0088] In this embodiment, the filter unit 150 is described as being formed at the most downstream side of the aerosol product 100, but as shown in Fig. 8, a recess 190 may be formed downstream of the filter unit 150. The recess 190 has a structure in which the wrapper 170 surrounding the filter unit 150 extends downstream from the filter unit 150. That is, in this embodiment, the wrapper 170 extends further outside the filter unit 150 than in the aerosol product 100 of the previous embodiment. Due to the shape of the wrapper 170, the filter unit 150 may have a recessed rod shape.

[0089] The recess 190 prevents nicotine traces generated on the end of the downstream filter part 150 from being easily exposed to the outside. Therefore, nicotine traces generated on the filter part 150 of the aerosol product 100 during smoking or after smoking is completed are not exposed to the outside, resulting in a good appearance.

[0090] 3 and 4, in the aerosol product 100 according to this embodiment, the cooling unit 130 is disposed between the tobacco medium unit 110 and the filter unit 150, and is capable of cooling the high-temperature aerosol passing through the cooling unit 130. The high-temperature aerosol emitted from the tobacco medium unit 110 is cooled as it moves through the cooling unit 130, and the cooled aerosol passes through the filter unit 150 and is delivered to the user. This prevents the high-temperature aerosol from being directly delivered to the user.

[0091] The cooling unit 130 may be formed in a tubular shape that allows the aerosol to pass through. Specifically, the cooling unit 130 includes a body 135 having a through hole 133 formed therein. The through hole 133 is a space formed in the center of the cooling unit 130, and the aerosol moves from the tobacco medium unit 110 to the filter unit 150 through the through hole.

[0092] The high-temperature aerosol that has flowed into the inlet of the cooling unit 130 is cooled as it passes through the through-holes 133 of the cooling unit 130. During the aerosol cooling process, some of the heat contained in the aerosol may be discharged to the outside through the body 135 of the cooling unit 130. Here, a separate member containing PLA (polylactic acid) may be disposed inside the through-holes 133 of the cooling unit 130. For example, the inside of the through-holes 133 may be at least partially filled with PLA.

[0093] The body 135 of the cooling unit 130 may be made by adding a plasticizer such as triacetin to cellulose acetate tow. Alternatively, the body 135 of the cooling unit 130 may be made of a paper insert made of multiple papers. For example, the body 135 may be a paper insert made of an outer paper, a middle paper, and an inner paper, but is not limited to this and may be a single paper. Here, a cooling material may be coated on the inside of the paper insert, or a cooling film may be attached. Here, the cooling material or cooling film may include various materials having high thermal efficiency. However, the material and type of the body 135 of the cooling unit 130 are not necessarily limited thereto and may be changed within the scope of those skilled in the art.

[0094] When the body 135 of the cooling section 130 is made of cellulose acetate tow, the mono-denier of the filaments constituting the cellulose acetate tow may be 3 to 20. Preferably, the mono-denier of the filaments of the body 135 may be 9 to 15.

[0095] The cross section of the filament constituting the body 135 may be Y-shaped. Here, the filament may refer to a single long fiber constituting the cellulose acetate tow.

[0096] The body 135 may have a doughnut-shaped cross section due to the through-hole 133. In this case, the inner diameter of the body 135 may be 2 mm or more. Preferably, the inner diameter of the body 135 may be 3.8 to 4.2 mm.

[0097] Here, a plurality of openings 160 may be formed in the body 135 so that outside air can flow in or inside air can flow out. The plurality of openings 160 may be formed spaced apart from each other in the circumferential direction of the body 135.

[0098] In this embodiment, a plurality of openings 160 are disposed on the outlet side of the cooling unit 130, i.e., adjacent to the filter unit 150. The aerosol passing through the cooling unit 130 can be further cooled by the outside air flowing in through the plurality of openings 160. This allows the aerosol flowing into the filter unit 150 to be cooled again, thereby preventing the high-temperature aerosol from being inhaled into the user's mouth.

[0099] In this embodiment, the multiple openings 160 are described as being arranged on the outlet side of the cooling section 130, but the position of the multiple openings 160 is not necessarily limited to this, and the multiple openings 160 may be arranged at other positions on the cooling section 130, for example, on the inlet side of the cooling section 130 or in the central region of the cooling section 130.

[0100] According to this embodiment, the body 135 of the cooling unit 130 contains a coolant 131. The coolant 131 can additionally cool the mainstream smoke M passing through the through holes 133 of the body 135. More specifically, the coolant 131 can cool the mainstream smoke M while absorbing a portion of the aerosol contained in the mainstream smoke M passing through the through holes 133 formed inside the body 135.

[0101] In this case, the coolant 131 may include activated carbon. Activated carbon is produced by carbonizing wood, bamboo, sawdust, coconut shells, lignin, lignite, peat, etc., and then activating and purifying the carbon. Activated carbon is classified into powdered activated carbon and granular activated carbon depending on its form. In this embodiment, the activated carbon used as the coolant 131 is powdered activated carbon or granular activated carbon.

[0102] Activated carbon has a specific surface area that can absorb the aerosols contained in mainstream smoke M. The specific surface area of activated carbon is 600 to 3000 m 2 In this embodiment, the specific surface area of the activated carbon may be 700 to 2500 m / g. 2 / g. Alternatively, in this embodiment, the specific surface area of the activated carbon may be 1000 to 2000 m 2However, the specific surface area of the activated carbon is not necessarily limited to the above range, and the activated carbon may have any specific surface area that is sufficient to absorb the aerosol of mainstream smoke.

[0103] Furthermore, the activated carbon may have a particle size that allows it to be positioned within the fibers that make up the body 135. The particle size of the activated carbon may be 20 to 100 mesh. Preferably, the particle size of the activated carbon may be 25 to 80 mesh. The particle size of the activated carbon may be appropriately selected within the above range depending on the fibers that make up the body 135.

[0104] FIG. 9 is a diagram for explaining the cooling process of mainstream smoke by the coolant in the cooling section.

[0105] 9, mainstream smoke M that has passed through the tobacco medium portion 110 passes through the through holes 133 formed in the cooling portion 130. At this time, the coolant 131 absorbs some of the aerosol contained in the mainstream smoke M, and as the aerosol is absorbed by the coolant 131, heat (H) is released, cooling the mainstream smoke M. As a result, the mainstream smoke M is naturally cooled as it passes through the through holes 133 of the body 135, and additional cooling occurs as the coolant 131 of the body 135 absorbs some of the aerosol from the mainstream smoke M.

[0106] According to this embodiment, the temperature of the mainstream smoke M delivered to the user can be cooled to a range of 55°C to 65°C by the coolant 131 of the cooling unit 130. In conventional aerosol products in which the coolant 131 is not included in the cooling unit 130, the temperature of the mainstream smoke M delivered to the user can exceed 70°C depending on the usage environment. Such a high temperature can cause inconvenience to the user while smoking, and in hot and humid environments, can even cause burns to the user's lips. When the coolant 131 is included in the body 135 of the cooling unit 130 as in this embodiment, the temperature of the mainstream smoke M delivered to the user can be maintained within the above temperature range, preventing the user from experiencing inconvenience or being burned.

[0107] 10 is a schematic cross-sectional view of a conventional aerosol product in which an activated carbon unit 180 containing activated carbon is disposed between a cooling unit 130 and a filter unit 150. The activated carbon unit 180 can cool mainstream smoke M that has passed through the cooling unit 130. However, since the activated carbon unit 180 is positioned in the direction of the mainstream smoke, it not only additionally cools the mainstream smoke but also significantly reduces the amount of atomization. Compared to such conventional aerosol products, the aerosol product 100 according to this embodiment can additionally cool mainstream smoke without reducing the amount of atomization.

[0108] According to this embodiment, the cooling agent 131 may be uniformly distributed in the cooling unit 130. More specifically, the cooling agent 131, i.e., activated carbon, may be distributed at a uniform concentration along the length of the body 135 of the cooling unit 130. That is, the concentration of the cooling agent 131 in the cooling unit 130 becomes uniform from the tobacco medium portion 110 to the filter portion 150. Here, the concentration of the cooling agent 131 indicates the amount of the cooling agent 131, i.e., activated carbon, contained inside the body 135 per unit length.

[0109] Meanwhile, the coolant 131 may be distributed non-uniformly in the cooling unit 130. More specifically, as in the modified examples of this embodiment shown in FIGS. 11 to 18, the coolant 131 is distributed at a non-uniform concentration along the length of the body 135 of the cooling unit 130.

[0110] 11 and 12, the concentration of the cooling agent 131 in the cooling section 130 is higher at the inlet side of the cooling section 130 adjacent to the tobacco medium section 110 than at other locations in the cooling section 130.

[0111] 11, the coolant 131 is disposed throughout the fuselage 135 along the length of the fuselage 135, but the coolant 131 is disposed at a higher concentration on the inlet side of the cooling section 130. On the other hand, in FIG. 12, the coolant 131 is disposed only on the inlet side of the cooling section 130, and the coolant 131 is not disposed in the rest of the cooling section 130 excluding the inlet side.

[0112] 13 and 14, the concentration of the coolant 131 in the cooling section 130 is higher at the outlet side of the cooling section 130 adjacent to the filter section 150 than at other locations in the cooling section 130.

[0113] 13, the coolant 131 is disposed throughout the fuselage 135 along the length of the fuselage 135, but the coolant 131 is disposed at a higher concentration on the outlet side of the cooling section 130. On the other hand, in FIG. 14, the coolant 131 is disposed only on the outlet side of the cooling section 130, and the coolant 131 is not disposed in the rest of the cooling section 130 excluding the outlet side.

[0114] 15 and 16, the concentration of the coolant 131 in the cooling unit 130 is higher in the central region of the cooling unit 130 than in other positions of the cooling unit 130. That is, the concentration of the coolant 131 in the central region of the cooling unit 130 is higher than that in the end regions of the cooling unit 130.

[0115] In Fig. 15, the coolant 131 is disposed throughout the body 135 along the length of the body 135, but the coolant 131 is disposed at a higher concentration in the central region of the cooling unit 130. That is, the coolant 131 is disposed at a higher concentration in the central region between the inlet side and the outlet side of the cooling unit 130. On the other hand, in Fig. 16, the coolant 131 is disposed only in the central region, and the coolant 131 is not disposed in the rest of the cooling unit 130 except for the central region.

[0116] 17 and 18, the concentration of the coolant 131 in the cooling section 130 is lower in the central region of the cooling section 130 than in other positions of the cooling section 130. That is, the concentration of the coolant 131 in the central region of the cooling section 130 is lower than that at both side ends of the cooling section 130.

[0117] 17, the coolant 131 is disposed throughout the fuselage 135 along the length of the fuselage 135, but the coolant 131 is disposed at a lower concentration in the central region of the cooling section 130. That is, the coolant 131 is disposed at a lower concentration in the central region between the inlet side and the outlet side of the cooling section 130. On the other hand, in FIG. 18, the coolant 131 is disposed only in the end regions on both sides of the cooling section 130, and the coolant 131 is not disposed in the central region.

[0118] 4, the aerosol product 100 according to this embodiment can be packaged in a wrapper 170. The wrapper 170 can wrap the tobacco medium portion 110, the cooling portion 130, and the filter portion 150, which are arranged in a row. When the wrapper 170 wraps the tobacco medium portion 110, the cooling portion 130, and the filter portion 150 in this manner, the aerosol product 100 can maintain its inherent cylindrical shape.

[0119] The wrapper 170 can wrap the entire outer periphery of the tobacco medium portion 110 , the cooling portion 130 and the filter portion 150 .

[0120] The tobacco medium portion 110, the cooling portion 130, and the filter portion 150 that form the aerosol product 100 according to this embodiment may each be individually wrapped in a separate wrapper (not shown). When the tobacco medium portion 110 includes multiple segments, each of the multiple segments may be wrapped in a different wrapper, or the multiple segments may be wrapped in a single wrapper. When the tobacco medium portion 110, the cooling portion 130, and the filter portion 150 are individually wrapped in this manner, the individually wrapped tobacco medium portion 110, the cooling portion 130, and the filter portion 150 may be rewrapped in a wrapper 170.

[0121] The wrapper 170 may have a plurality of openings (not shown) formed therein to allow external air to flow into or internal air to flow out of the aerosol product 100. The plurality of openings may be formed at positions corresponding to the plurality of openings 160 of the cooling section 130.

[0122] The wrapper 170 may be made of conventional wrapping paper. For example, the wrapper 170 may be porous or non-porous wrapping paper.

[0123] The wrapper 170 may include a predetermined material. Here, the predetermined material may be silicon, but is not necessarily limited to this. 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, or electrical insulation. However, any material other than silicon that has the above properties may be applied to the wrapper 170 without limitation.

[0124] Furthermore, the wrapper 170 contains a non-flammable material, which can prevent the aerosol product 100 of this embodiment from burning. For example, if the tobacco medium portion 110 is heated by the heating unit 370 of the aerosol generating device 300, the aerosol product 100 may burn. Specifically, if the temperature of any one of the substances contained in the tobacco medium portion 110 rises above the ignition point, the aerosol product 100 may burn.

[0125] The wrapper 170 can prevent the aerosol generating device 300 from being contaminated by substances generated from the aerosol generating product 100 according to this embodiment. When smoking, a liquid substance may be generated within the aerosol generating product 100. For example, when the aerosol generated from the aerosol generating product 100 is cooled by the outside air, a liquid substance such as water is generated.

[0126] The wrapper 170 wraps the tobacco medium portion 110, the cooling portion 130, and the filter portion 150, thereby preventing the liquid substance generated within the aerosol product 100 from leaking to the outside of the aerosol product 100. Therefore, the inside of the aerosol generation device 300 can be prevented from being contaminated by the liquid substance generated from the aerosol product 100.

[0127] Because the wrapper 170 forms the outermost surface of the aerosol product 100, the shape of the aerosol product 100 can be changed according to the shape of the wrapper 170. For example, letters, patterns, symbols, images, etc. may be printed on the wrapper 170, and since the letters, patterns, symbols, images, etc. printed on the wrapper 170 can be changed, the aerosol product 100 can provide various visual information.

[0128] An aerosol generating device into which an aerosol production article according to one embodiment of the present disclosure is inserted will now be described.

[0129] FIG. 19 is a schematic diagram of an aerosol generating device into which an aerosol production article according to one embodiment of the present disclosure is inserted.

[0130] 19, the aerosol generating device 300 according to this embodiment includes a heating unit 370, a power supply unit 330, a control unit 310, and an aerosol generating unit 350. It will be understood by those skilled in the art that the aerosol generating device 300 may further include other general-purpose components in addition to the components shown in FIG.

[0131] 19 shows the power supply unit 330, the control unit 310, and the aerosol generation unit 350 arranged in a line, but the arrangement of the power supply unit 330, the control unit 310, and the aerosol generation unit 350 may be changed as necessary. Also, although the aerosol generation unit 350 is shown to be included in FIG. 19, the aerosol generation unit 350 may be omitted, and the aerosol product 100 may be operated by simply being heated by the heating unit 370.

[0132] The aerosol production product 100 may be inserted into the aerosol generation device 300. The aerosol production product 100 may be inserted and fixed in the aerosol generation device 300 by a fixing means. In this embodiment, the tobacco medium portion 110 of the aerosol production product 100 corresponds to the fixing means. However, other fixing means may be added in addition to the tobacco medium portion 110.

[0133] The heating unit 370 heats the aerosol product 100. The heating unit 370 is heated by the power supplied from the power supply unit 330, and the heating unit 370 transfers heat to the aerosol product 100.

[0134] The heating element 370 may be an electrical resistive heater. The heating element 370 may include an electrically conductive track, and the power source 330 may provide electrical power to the heating element 370, which may then pass an electrical current through the electrically conductive track, thereby allowing the heating element 370 to heat the aerosol product 100.

[0135] As another example, the heating unit 370 may be an induction heater. The heating unit 370 may include an electrically conductive coil for inductively heating the aerosol product article 100, and the aerosol product article 100 may include a susceptor that can be heated by the induction heater.

[0136] 19 is shown as being disposed externally of the aerosol product 100, but is not necessarily limited to this. The heating unit 370 may include at least one of a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and may heat the interior, exterior, or both the interior and exterior of the aerosol product 100 depending on the shape of the at least one heating element included in the heating unit 370.

[0137] The power supply unit 330 supplies power used in the aerosol generating device 300. For example, the power supply unit 330 supplies power to heat the heating unit 370 and supplies power necessary for the operation of the control unit 310. The power supply unit 330 also supplies power necessary for the operation of the display, sensors, motors, etc. of the aerosol generating device 300.

[0138] The control unit 310 controls the overall operation of the aerosol generating device 300. Specifically, the control unit 310 controls the operation of the power supply unit 330 and other components included in the aerosol generating unit 350. The control unit 310 can also check the status of each component of the aerosol generating device 300 to determine whether the aerosol generating device 300 is in an operable state.

[0139] The aerosol generating unit 350 heats the liquid composition to generate an aerosol, and the generated aerosol passes through the aerosol producing product 100 and is delivered to the user. In other words, the aerosol generated by the aerosol generating unit 350 flows into the tobacco medium portion 110 of the aerosol producing product 100.

[0140] The aerosol generating unit 350 includes, but is not limited to, a liquid storage unit, a liquid transfer means, and a heating element. For example, the liquid storage unit, the liquid transfer means, and the heating element may be included in the aerosol generating device 300 as independent modules.

[0141] The liquid storage unit can store a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco aroma component, or a liquid containing a non-tobacco substance. The liquid storage unit may be detachable or may be integral with the aerosol generating device 300.

[0142] When the aerosol-generating unit 350 according to an embodiment of the present disclosure contains a liquid containing a non-tobacco substance, the liquid composition stored in the liquid storage unit included in the aerosol-generating unit 350 may not contain nicotine, and the aerosol generated from the aerosol-generating unit 350 will flow into the tobacco medium unit 110 without containing nicotine. In this case, the aerosol not containing nicotine will pass through the tobacco medium unit 110 and adsorb nicotine, and the aerosol that has passed through the tobacco medium unit 110 will contain nicotine.

[0143] The liquid composition contained in the aerosol generator 350 may include water, solvent, ethanol, plant extract, fragrance, flavoring, or vitamin mixture. Flavoring includes, but is not limited to, menthol, peppermint, spearmint oil, and various fruit fragrance components. Flavoring includes components that can provide the user with various flavors or tastes. 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 include an aerosol-forming agent such as glycerin and propylene glycol.

[0144] Although one embodiment of the present disclosure has been described above, a person having ordinary skill in the art would understand that the present disclosure can be modified and changed in various ways by adding, changing, deleting, or adding components within the scope of the concept of the present disclosure as set forth in the claims, and that this also falls within the scope of the present disclosure.
