Description

Technical Field

[0001] This disclosure relates to aerosol generating articles and aerosol generating apparatus. Background Technology

[0002] Generally speaking, tobacco refers to a perennial herbaceous plant belonging to the Solanaceae family of dicotyledonous plants. Recently, it has also come to refer to products intended for smoking, consisting of tobacco leaves encased in cigarette paper with a filter on one side. There are thousands of tobacco products on the global market, in various shapes and forms.

[0003] In the case of combustible tobacco products such as cigarettes, cigars and hookahs, tobacco smoke contains not only nicotine aerosols, but also a variety of components such as tar, nitrosamines, hydrocarbons and carbon monoxide.

[0004] As an alternative to compensate for the drawbacks of such combustible tobacco products, methods for generating aerosols by heating the aerosol-generating substances in cigarettes instead of burning the cigarettes are widely used, and the demand for this is increasing. To meet this demand, research is actively underway on heated cigarettes or heated aerosol generating devices.

[0005] Specifically, aerosol generating devices have a form similar to traditional combustible tobacco products, and they generate mainstream smoke containing aerosols by heating aerosol-generating substances in heated cigarettes using devices such as heaters or ultrasonic vibrations. The advantage of aerosol generating devices is that they minimize emissions of components such as tar, while simultaneously providing smokers with greater satisfaction. Therefore, aerosol generating devices are attracting attention as a new market alternative to traditional combustible tobacco products.

[0006] However, heated cigarettes, heated by an aerosol generator, produce high-temperature mainstream smoke, which can be directly delivered to the user. This high-temperature mainstream smoke may cause discomfort or burns to the user. Summary of the Invention

[0048] In the following, an aerosol-generating article according to an embodiment of the present disclosure will be described.

[0049] Figure 1 This is a schematic exploded perspective view showing an aerosol-generating article according to an embodiment of the present disclosure. Figure 2 This is a schematic perspective view showing an aerosol-generating article according to an embodiment of the present disclosure. Figure 3 yes Figure 2 An enlarged view of the interior of segment A shown. Figure 4 This is a cross-sectional view showing an aerosol-generating article according to an embodiment of the present disclosure.

[0050] Reference Figures 1 to 4 The aerosol generating article 100 according to embodiments of the present disclosure may include a tobacco medium portion 110, a cooling portion 130, a filter portion 150, and a packaging component 170. Here, those skilled in the art related to this embodiment will understand that, in addition to... Figures 1 to 4 Other general-purpose components besides those shown may also be included in the aerosol-generating article 100.

[0051] According to this embodiment, the aerosol generating article 100 can be inserted into the aerosol generating device 300 (see...). Figure 19The aerosol generating device 300 will be described in more detail below. In this case, when the aerosol generating article 100 is heated, mainstream smoke can be delivered to the user. Mainstream smoke can be an airflow flowing from upstream to downstream within the aerosol generating article 100. Here, the term "upstream" can refer to the side where the tobacco medium portion 110 is located, and the term "downstream" can refer to the side where the filter portion 150 is located. The user of the aerosol generating article 100 can inhale the mainstream smoke through the downstream end of the aerosol generating article 100.

[0052] The aerosol generating article 100 can have a cylindrical shape. In this case, the diameter of the aerosol generating article 100 can be in the range of 4.7 mm to 9.9 mm. Each of the tobacco medium portion 110, the cooling portion 130, and the filter portion 150 can also have a cylindrical shape with a diameter of 4.7 mm to 9.9 mm.

[0053] Additionally, the length of the aerosol generating article 100 can be in the range of 31 mm to 60 mm. The length of the tobacco medium portion 110 can be in the range of 17 mm to 30 mm. The length of the cooling portion 130 can be in the range of 4 mm to 10 mm, and the length of the filter portion 150 can be in the range of 10 mm to 20 mm.

[0054] The shape, diameter, and length of the aerosol generating article 100 and its components are exemplary, and this disclosure is not necessarily limited thereto. The shape and size of the aerosol generating article 100 may be partially modified to the extent that can be employed by those skilled in the art.

[0055] The tobacco medium portion 110 is located upstream of the aerosol-generating article 100 and may include the tobacco medium that generates the aerosol. The tobacco medium of the tobacco medium portion 110 contains nicotine, thereby providing users who inhale mainstream smoke with the unique taste and aroma of cigarettes.

[0056] When the aerosol generating article 100 is heated by the aerosol generating apparatus 300—which will be described in more detail below—and the aerosol generated by the aerosol generating apparatus 300 is introduced into the aerosol generating article 100, nicotine can be adsorbed onto the surface of the introduced aerosol as the aerosol passes through the tobacco medium portion 110 and is delivered to the user.

[0057] Here, the nicotine contained in the tobacco medium can be at least one of free nicotine and nicotine salt, and the nicotine can be naturally occurring nicotine or synthetic nicotine.

[0058] Nicotine salts can be formed by adding suitable acids, including organic and inorganic acids, to nicotine. The acid used to form nicotine salts can be appropriately selected considering factors such as blood nicotine absorption rate, heating temperature of the heater, flavor, and solubility. For example, the acid used to form nicotine salts can be 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, hexanoic 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, malonic acid, or malic acid, or a mixture of at least two acids selected from the above group, but is not limited thereto.

[0059] Meanwhile, the tobacco medium in the tobacco medium portion 110 can be made into various forms. For example, the tobacco medium can be made into sheet or strip form. Additionally, the tobacco medium can be made into tobacco shreds obtained by finely cutting tobacco sheets. Furthermore, the tobacco medium can be made into granules containing tobacco.

[0060] The tobacco medium portion 110 may have a cylindrical shape. However, the shape of the tobacco medium portion 110 is not necessarily limited to this, and it may be a rod shape with various cross-sections.

[0061] In this case, the tobacco medium portion 110 can be manufactured by folding tobacco sheets into a cylindrical shape or by molding tobacco strips, tobacco shreds or tobacco pellets into a cylindrical shape.

[0062] When the tobacco medium portion 110 is made from multiple tobacco strips obtained by finely cutting tobacco sheets, the tobacco medium portion 110 can be formed by combining the multiple tobacco strips in the same direction (e.g., parallel to each other) or randomly. Specifically, the tobacco medium portion 110 can be formed by combining multiple tobacco strips, and can create multiple longitudinal channels for allowing aerosols to pass through. In this case, the longitudinal channels can be uniform or non-uniform, depending on the size and arrangement of the tobacco strips.

[0063] The tobacco medium portion 110 may also include aerosol-generating substances to increase the amount of vaporization. For example, the aerosol-generating substances may include at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but are not necessarily limited to these.

[0064] The tobacco medium portion 110 may also include flavoring materials to add flavor to the aerosol. For example, the tobacco medium portion 110 may include other additives such as flavoring agents, wetting agents, and / or organic acids. Alternatively, flavoring liquids, such as menthol or humectants, can be added to the tobacco medium portion 110 by spraying the flavoring liquid onto it.

[0065] In this context, as a non-limiting example, flavoring agents may include licorice, sucrose, fructose syrup, sage, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarella, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, peppermint oil, cinnamon, coriander, brandy, jasmine, chamomile, menthol, cinnamon, ylang-ylang, tanshinone, spearmint, ginger, coriander, or coffee. Additionally, wetting agents may include glycerin or propylene glycol.

[0066] The tobacco medium portion 110 may be surrounded by a heat-conducting material. The heat-conducting material can improve the thermal conductivity applied to the tobacco medium portion 110 by uniformly distributing the heat transferred to it, thereby improving the tobacco flavor. For example, the heat-conducting material can be a metal foil, such as aluminum foil. However, the heat-conducting material is not necessarily limited to this, and various metal foils used as heat-conducting materials can be employed.

[0067] In this embodiment, the tobacco medium portion 110 may consist of at least one segment. As a non-limiting example, the tobacco medium portion 110 may include one segment, two segments, or three segments. Specifically, Figure 4 The tobacco medium portion 110 according to this embodiment shown may include a section. Alternatively, as Figure 5 and Figure 6 As shown, the tobacco medium portion 110 may include two sections. Alternatively, as... Figure 7 As shown, the tobacco medium portion 110 may include three sections.

[0068] refer to Figure 4 According to this embodiment, the tobacco medium portion 110 may include a section. This section of the tobacco medium portion 110 may be filled with tobacco medium. In other words, in this embodiment, the tobacco medium portion 110 may include a section filled with tobacco medium.

[0069] In this case, segments can be manufactured by folding tobacco sheets into a cylindrical shape, or by molding tobacco strips, shredded tobacco, or tobacco pellets into a cylindrical shape. Additionally, the segments may include aerosol-generating substances and / or flavoring materials to increase atomization.

[0070] Additionally, the section of the tobacco medium portion 110 can be connected to a heater 370 of an aerosol generating apparatus 300 for heating the aerosol generating article 100 (see [link]). Figure 19 To heat. Figure 19In the diagram, heater 370 is shown disposed around aerosol generating article 100, but is not necessarily limited thereto, and heater 370 may be inserted into tobacco medium portion 110 to heat tobacco medium portion 110.

[0071] The tobacco medium portion 110 may also include configurations for identifying the aerosol-generating article 100. The aerosol-generating article 100 may exhibit various flavors and aromas and may include configurations (not shown) for identifying various types of aerosol-generating articles 100. For example, the tobacco medium portion 110 may include a metal foil to alter the inductance of a coil, thereby identifying the aerosol-generating article included in the aerosol-generating apparatus 300. In this case, the metal foil may be disposed on the outer peripheral surface of the tobacco medium portion 110.

[0072] At the same time, Figure 5 and Figure 6 In the modified example shown, the tobacco medium portion 110 may include two sections. One of the two sections may include the tobacco medium, while the other section may not include the tobacco medium.

[0073] refer to Figure 5 The tobacco medium portion 110 may include a first segment 111 and a second segment 119. The first segment 111 is a segment filled with tobacco medium and may be composed of the above-described... Figure 4 The sections of the tobacco medium portion 110 shown are made of the same material.

[0074] The second section 119 can be located at the upstream end of the aerosol generating article 100 and can prevent the first section 111 from being separated to the outside. In other words, the tobacco medium portion 110 according to this modified example can also be configured such that the second section 119 and the first section 111 are arranged sequentially from the upstream side.

[0075] The second section 119 prevents impurities from being introduced into the first section 111 from the outside, and the second section 119 also prevents liquefied aerosols from being introduced into the aerosol generating device 300 during smoking (see...). Figure 19 )middle.

[0076] In addition, when the aerosol generating article 100 is inserted into the aerosol generating device 300, the second section 119 can support the aerosol generating article 100, so that the aerosol generating article 100 is fixed to the aerosol generating device 300.

[0077] The second section 119 can be a cellulose acetate filter. For example, the second section 119 can be manufactured by adding a plasticizer, such as triacetin, to the cellulose acetate tow. Additionally, aerosol-generating substances can be contained within the cellulose acetate tow.

[0078] Nicotine can be removed from the aerosol-generating material included in the second section 119. For example, the second section 119 may include at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, or oleyl alcohol. However, the aerosol-generating material included in the second section 119 is not necessarily limited thereto. For example, the second section 119 may include a material in which glycerol and propylene glycol are mixed in a ratio of approximately 8:2. However, the above mixing ratio is exemplary, and this disclosure is not necessarily limited thereto.

[0079] Additionally, the second section 119 may include other additives, such as flavoring agents, wetting agents, and / or organic acids. However, the materials and types of the second section 119 are not necessarily limited thereto and can be modified to the extent that can be employed by those skilled in the art.

[0080] The second section 119 may have a through-hole to allow aerosol from the outside to be introduced through the through-hole to form a mainstream smoke inside the aerosol generating article 100. The through-hole formed in the second section 119 may have a circular or Y-shaped cross-section. However, the cross-sectional shape of the through-hole is not necessarily limited to this and can take various forms.

[0081] Meanwhile, when the second section 119 includes a rolled sheet impregnated with an aerosol-generating substance, through holes may not be formed in the second section 119.

[0082] When a portion of the aerosol generating article 100 is inserted into the aerosol generating device 300, the aerosol generated by the aerosol generating device 300 can be introduced into the aerosol generating article 100 through the second section 119. The aerosol can form a mainstream smoke within the aerosol generating article 100 and be delivered to the user. Additionally, aerosols generated within the second section 119, which includes the aerosol generating material, can form a mainstream smoke and be delivered to the user.

[0083] The second section 119 may further include a configuration for identifying the aerosol-generating article 100. The aerosol-generating article 100 may exhibit a variety of tastes and aromas, and may include configurations for identifying various types of aerosol-generating articles 100. For example, the second section 119 may include a metal foil to alter the inductance of a coil, thereby identifying the aerosol-generating article included in the aerosol-generating apparatus 300. However, this disclosure is not necessarily limited thereto, and the configuration for identifying the aerosol-generating article 100 may be included in the first section 111 in addition to the second section 119.

[0084] refer to Figure 6The tobacco medium portion 110 may include a first section 111 and a second section 117.

[0085] The first section 111 may be located at the upstream end of the aerosol-generating article. The first section 111 is a section filled with tobacco medium, and the first section 111 may be composed of... Figure 5 It is made of the same material as the first section 111 shown above.

[0086] The second section 117 prevents the tobacco medium in the first section 111 from separating toward the cooling section 130, which will be described in more detail below. For example, when a heater for heating the aerosol-generating article 100 is inserted into the first section 111, the tobacco medium in the first section 111 can separate and move toward the cooling section 130. Because the second section 117 is provided between the first section 111 and the cooling section 130, it prevents the tobacco medium in the first section 111 from separating toward the cooling section 130.

[0087] The second section 117 can be composed of and Figure 5 It is made of the same material as the second section 119 shown above.

[0088] Additionally, the second segment 117 may have a through-hole to allow aerosols formed in or passing through the first segment 111 to be introduced through the through-hole. The through-hole formed in the second segment 117 may have a circular or Y-shaped cross-section. However, the cross-sectional shape of the through-hole is not necessarily limited to this and can take various forms.

[0089] Thus, the first segment 111 and the second segment 117 of the tobacco medium portion 110 can be respectively composed of and Figure 5 The first section 111 and the second section 119 of the tobacco medium portion 110 shown are made of the same material. However, the first section 111 and the second section 117 of the tobacco medium portion 110 can be made of the same material as... Figure 5 The first segment 111 and the second segment 119 shown are arranged in a different order. In other words, the tobacco medium portion 110 according to this modified example can be configured such that the first segment 111 and the second segment 117 are arranged sequentially from the upstream side.

[0090] At the same time, Figure 7 In the modified example shown, the tobacco medium portion 110 may include three segments. At least one of the three segments may include the tobacco medium.

[0091] refer to Figure 7The tobacco medium portion 110 may include a first section 111, a second section 113, and a third section 115. In this modified example, the first section 111, which includes the tobacco medium, may be located in the center, while the second section 113, the first section 111, and the third section 115 may be arranged sequentially from the upstream side.

[0092] The first segment 111 is the middle segment of the three segments of the tobacco medium portion 110. The first segment 111 is the segment filled with tobacco medium, and the first segment 111 can be composed of the segments described above. Figure 5 The first section 111 shown is made of the same material.

[0093] The second segment 113 and the third segment 115 may be arranged opposite to the first segment 111 located between the second segment 113 and the third segment 115. The second segment 113 and the third segment 115 may be formed by, for example... Figure 5 It is made of the same material as the second section 119 shown above.

[0094] The second section 113 prevents impurities from being introduced into the first section 111 from the outside, and also prevents liquefied aerosols from being introduced into the aerosol generating device 300 during smoking. Furthermore, the second section 113 can maintain consistency with the first section 111 in structure, function, and materials. Figure 5 The second section 119 shown above is the same.

[0095] The third section 115 prevents the tobacco medium in the first section 111 from separating towards the cooling section 130. Furthermore, the third section 115 maintains consistency with the first section 111 in structure, function, and materials. Figure 6 The second section 117 shown above is the same.

[0096] Thus, in this modified example, the tobacco medium portion 110 can be configured such that the second segment 113 and the third segment 115 are arranged opposite to the first segment 111 which includes the tobacco medium.

[0097] Return to reference Figures 1 to 4 In this embodiment, the filter portion 150 may be located at the downstream end of the aerosol-generating article to be spaced apart from the tobacco medium portion 110. The filter portion 150 may filter out at least one of the substances included in the mainstream smoke.

[0098] The filter tip portion 150 may be a cellulose acetate filter tip, and the filter tip portion 150 may be manufactured by adding a plasticizer, such as triacetin, to the cellulose acetate tow. However, the material and type of the filter tip portion 150 are not necessarily limited thereto, and modifications may be made to the extent that can be made by those skilled in the art.

[0099] The filter portion 150 may have a cylindrical shape. However, the shape of the filter portion 150 is not necessarily limited to this, and may take various shapes that correspond to the shape of the tobacco medium portion 110.

[0100] The filter portion 150 can be manufactured to generate fragrance. For example, a fragrance liquid can be sprayed onto the filter portion 150, or individual fibers coated with a fragrance liquid can be included inside the filter portion 150.

[0101] Alternatively, the filter portion 150 may include at least one capsule (not shown). The capsule may generate a fragrance or aerosol. For example, the capsule may have a structure that encapsulates a fragrance-containing liquid with a membrane. In this case, the capsule may have a spherical or cylindrical shape, but the shape of the capsule is not necessarily limited to these.

[0102] In this embodiment, the filter portion 150 is described as being formed on the most downstream side of the aerosol generating article 100. However, as Figure 8 As shown, a recessed portion 190 may be formed downstream of the filter tip portion 150. The recessed portion 190 has a structure in which the package 170 surrounding the filter tip portion 150 extends further downstream beyond the filter tip portion 150. In other words, in this embodiment, compared to the aerosol generating article 100 described above according to the embodiment, the package 170 extends further outward beyond the filter tip portion 150. Depending on the shape of the package 170, the filter tip portion 150 may have a recessed rod shape.

[0103] The recessed portion 190 prevents nicotine stains formed at the end of the filter portion 150 from being easily exposed to the outside. Therefore, nicotine stains formed on the filter portion 150 of the aerosol generating article 100 during or after smoking are not exposed to the outside, resulting in an improved aesthetic appearance.

[0104] Reference Figure 3 and Figure 4 In the aerosol generating article 100 according to this embodiment, a cooling section 130 may be provided between the tobacco medium section 110 and the filter section 150, and the cooling section 130 can cool the high-temperature aerosol passing through it. The high-temperature aerosol from the tobacco medium section 110 can be cooled while moving inside the cooling section 130, and the cooled aerosol can pass through the filter section 150 and be delivered to the user. This prevents the high-temperature aerosol from being directly delivered to the user.

[0105] The cooling section 130 may have a tubular shape to allow aerosols to pass through it. Specifically, the cooling section 130 may include a body 135 having a through-hole 133 therein. The through-hole 133 is a space formed in the center of the cooling section 130, and the through-hole 133 allows aerosols to move from the tobacco medium section 110 to the filter section 150 through the through-hole 133.

[0106] The high-temperature aerosol introduced into the inlet of the cooling section 130 can be cooled as it passes through the through-hole 133 of the cooling section 130. During the cooling of the aerosol, a portion of the heat contained in the aerosol can pass through the body 135 of the cooling section 130 and be discharged to the outside. In this case, a separate component including polylactic acid (PLA) can be provided in the through-hole 133 of the cooling section 130. For example, the interior of the through-hole 133 can be at least partially filled with PLA.

[0107] The body 135 of the cooling section 130 can be manufactured by adding a plasticizer, such as triacetin, to the cellulose acetate tow. Alternatively, the body 135 of the cooling section 130 can be made of laminated paper comprising multiple paper layers. For example, the body 135 can be made of laminated paper comprising an outer paper layer, an intermediate paper layer, and an inner paper layer, but is not necessarily limited thereto, and can also be made of a single layer of paper. In this case, the inner side of the laminated paper can be coated with a cooling material or can be covered with a cooling film. Here, the cooling material or cooling film can include various materials with high thermal efficiency. However, the material and type of the body 135 of the cooling section 130 are not limited thereto, and modifications can be made within the scope that can be employed by those skilled in the art.

[0108] When the body 135 of the cooling section 130 is made of cellulose acetate tow, the denier of the filaments constituting the cellulose acetate tow can be in the range of 3 to 20. Preferably, the denier of the filaments of the body 135 is in the range of 9 to 15.

[0109] Additionally, the filaments constituting the body 135 may have a Y-shaped cross-section. Here, the term "filament" may refer to a long bundle of fibers constituting the cellulose acetate tow.

[0110] Because of the through-hole 133, the body 135 can have an annular cross-section. In this case, the inner diameter of the body 135 can be equal to or greater than 2 mm. In some embodiments, the inner diameter of the body 135 is in the range of 3.8 mm to 4.2 mm.

[0111] Here, the body 135 may have a plurality of openings 160 for allowing external air to be introduced or internal air to be exhausted through the openings. The plurality of openings 160 may be formed to be spaced apart from each other in the circumferential direction of the body 135.

[0112] In this embodiment, multiple openings 160 may be arranged on the outlet side of the cooling section 130 (i.e., the side adjacent to the filter section 150). The aerosol passing through the cooling section 130 can be further cooled by external air introduced through the multiple openings 160. Thus, the aerosol introduced into the filter section 150 can be cooled again, thereby preventing high-temperature aerosol from being directly inhaled into the user's mouth.

[0113] In this embodiment, although a plurality of openings 160 are described as being arranged on the outlet side of the cooling section 130, the location of the plurality of openings 160 is not necessarily limited to this. The plurality of openings 160 may be arranged at another location 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.

[0114] According to this embodiment, the cooling material 131 may be included in the body 135 of the cooling section 130. The cooling material 131 may further cool the mainstream smoke M passing through the through-holes 133 of the body 135. More specifically, the cooling material 131 may cool the mainstream smoke M by absorbing a portion of the aerosol contained in the mainstream smoke M passing through the through-holes 133 formed in the body 135.

[0115] In this case, the cooling material 131 may include activated carbon. Activated carbon can be produced by processing wood, bamboo, sawdust, coconut shell, lignin, lignite, peat, etc., through carbonization, activation, and refining. Activated carbon can be classified into powdered activated carbon and granular activated carbon according to its shape. In this embodiment, the activated carbon used as the cooling material 131 may be either powdered activated carbon or granular activated carbon.

[0116] Activated carbon can possess a specific surface area capable of absorbing aerosols contained in mainstream smoke M. The specific surface area of ​​activated carbon can be between 600 m². 2 / g to 3,000m 2 In some embodiments, the specific surface area of ​​the activated carbon can be in the range of / g. 2 / g to 2,500m 2 In some embodiments, the specific surface area of ​​the activated carbon can be in the range of / g. 2 / g to 2,000m 2 The specific surface area of ​​activated carbon is within the range of / g. However, the specific surface area of ​​activated carbon is not necessarily limited to the above range, and activated carbon can have any specific surface area capable of absorbing aerosols in mainstream smoke.

[0117] Additionally, the activated carbon can have a particle size that allows it to be located within the fibers constituting the body 135. The particle size of the activated carbon can be in the range of 20 mesh to 100 mesh. Preferably, the particle size of the activated carbon is in the range of 25 mesh to 80 mesh. The particle size of the activated carbon can be appropriately selected within the above range depending on the fibers constituting the body 135.

[0118] Figure 9 It is a schematic view illustrating the process of cooling mainstream smoke through cooling materials in the cooling section.

[0119] refer to Figure 9 The mainstream smoke M passing through the tobacco medium section 110 can pass through the through-holes 133 formed in the cooling section 130. At this time, the cooling material 131 absorbs a portion of the aerosols contained in the mainstream smoke M. When the aerosols are absorbed by the cooling material 131, heat H is released, and the mainstream smoke M is thus cooled. Therefore, in addition to the natural cooling of the mainstream smoke M as it passes through the through-holes 133 of the body 135, further cooling occurs during the absorption of a portion of the aerosols in the mainstream smoke M by the cooling material 131 of the body 135.

[0120] According to this embodiment, the mainstream smoke M delivered to the user via the cooling material 131 of the cooling section 130 can be cooled to a temperature in the range of 55°C to 65°C. In the case of a prior art aerosol-generating article that does not include the cooling material 131 in the cooling section 130, the temperature of the mainstream smoke M delivered to the user can exceed 70°C, depending on the usage environment. Due to such high temperatures, the user may experience discomfort while smoking, or the user's lips may be burned in a hot and humid environment. As in this embodiment, when the cooling material 131 is included in the body 135 of the cooling section 130, the temperature of the mainstream smoke M delivered to the user can be maintained within the aforementioned temperature range, thereby preventing the user from experiencing discomfort or being burned.

[0121] at the same time, Figure 10 This is a schematic cross-sectional view of an aerosol generating article according to other embodiments, including an activated carbon portion 150 disposed between a cooling portion 130 and a filter portion 150. The mainstream smoke M passing through the cooling portion 130 is cooled by the activated carbon portion 180. However, since the activated carbon portion 180 is located in the direction of mainstream smoke movement, not only can the mainstream smoke be further cooled, but the atomization amount is also significantly reduced. Compared to the aerosol generating article according to this embodiment, the aerosol generating article 100 according to this embodiment can further cool the mainstream smoke without reducing the atomization amount.

[0122] According to this embodiment, the cooling material 131 can be uniformly disposed in the cooling section 130. More specifically, the cooling material 131 (i.e., activated carbon) can be disposed at a uniform concentration along the longitudinal direction of the body 135 of the cooling section 130. In other words, the concentration of the cooling material 131 in the cooling section 130 can be uniform from the tobacco medium section 110 to the filter section 150. Here, the concentration of the cooling material 131 refers to the amount of cooling material 131 (i.e., activated carbon) per unit length contained in the body 135.

[0123] Meanwhile, the cooling material 131 can be unevenly distributed within the cooling section 130. More specifically, when in such... Figures 11 to 18 In the modified example shown according to this embodiment, the cooling material 131 may be set at a non-uniform concentration along the longitudinal direction of the body 135 of the cooling portion 130.

[0124] refer to Figure 11 and Figure 12 The cooling material 131 in the cooling section 130 can be configured such that the concentration of the cooling material 131 is higher at the inlet side of the cooling section 130 adjacent to the tobacco medium section 110 than at other locations on the cooling section 130.

[0125] exist Figure 11 In this process, the cooling material 131 can be disposed throughout the entire body 135 along the longitudinal direction of the body 135, and the concentration of the cooling material 131 can be relatively high at the inlet side of the cooling section 130. On the other hand, in Figure 12 In this process, the cooling material 131 may be provided only at the inlet side of the cooling section 130, and the cooling material 131 may not be provided at any other location on the cooling section 130 other than the inlet side.

[0126] refer to Figure 13 and Figure 14 The cooling material 131 in the cooling section 130 can be configured such that the concentration of the cooling material 131 is higher at the outlet side of the cooling section 130 adjacent to the filter section 150 than at other locations on the cooling section 130.

[0127] exist Figure 13 In this process, the cooling material 131 can be disposed throughout the entire body 135 along the longitudinal direction of the body 135, and the concentration of the cooling material 131 can be relatively higher at the outlet side of the cooling section 130. On the other hand, in Figure 14 In this process, the cooling material 131 may be provided only at the outlet side of the cooling section 130, and the cooling material 131 may not be provided at any other location on the cooling section 130 except for the outlet side.

[0128] refer to Figure 15 and Figure 16 The cooling material 131 in the cooling section 130 can be configured such that the concentration of the cooling material 131 is higher in the central region of the cooling section 130 than at other locations on the cooling section 130. In other words, the concentration of the cooling material 131 can be higher in the central region of the cooling section 130 than in the opposite end regions of the cooling section 130.

[0129] exist Figure 15 In this configuration, the cooling material 131 can be disposed along the longitudinal direction of the body 135 throughout the entire body 135, and the concentration of the cooling material 131 can be relatively high in the central region of the cooling section 130. In other words, the concentration of the cooling material 131 can be relatively high in the central region between the inlet side and the outlet side of the cooling section 130. On the other hand, in... Figure 16 In the process, the cooling material 131 may be provided only in the central area, and the cooling material 131 may not be provided in other locations on the cooling section 130 except for the central area.

[0130] refer to Figure 17 and Figure 18 The cooling material 131 in the cooling section 130 can be configured such that the concentration of the cooling material 131 is lower in the central region of the cooling section 130 than at other locations on the cooling section 130. In other words, the concentration of the cooling material 131 in the central region of the cooling section 130 can be lower than in the opposite end region of the cooling section 130.

[0131] exist Figure 17 In this configuration, the cooling material 131 can be disposed along the longitudinal direction of the body 135 throughout the entire body 135, and the concentration of the cooling material 131 can be relatively low in the central region of the cooling section 130. In other words, the concentration of the cooling material 131 can be relatively low in the central region between the inlet side and the outlet side of the cooling section 130. On the other hand, in... Figure 18 In this process, the cooling material 131 may be provided only in the opposite end region of the cooling section 130, and the cooling material 131 may not be provided in the central region.

[0132] Return to reference Figure 4 The aerosol generating article 100 according to this embodiment can be packaged in a packaging package 170. The packaging package 170 can surround the tobacco medium portion 110, the cooling portion 130, and the filter portion 150 arranged in a row. In this way, when the packaging package 170 surrounds the tobacco medium portion 110, the cooling portion 130, and the filter portion 150, it can maintain the cylindrical shape that is the unique shape of the aerosol generating article 100.

[0133] The package 170 may surround the entire outer peripheral surface or some of the tobacco medium portion 110, cooling portion 130 and filter portion 150.

[0134] Each of the tobacco medium portion 110, cooling portion 130, and filter portion 150 constituting the aerosol generating article 100 according to this embodiment can be individually packaged in a separate package (not shown). When the tobacco medium portion 110 comprises multiple segments, each of the multiple segments can be packaged in a separate package, or the multiple segments can be packaged in a single package. Thus, when each of the tobacco medium portion 110, cooling portion 130, and filter portion 150 is individually packaged, the individually packaged tobacco medium portion 110, cooling portion 130, and filter portion 150 can be completely repackaged by the package 170.

[0135] The package 170 may have multiple openings (not shown) to allow external air to be introduced into the aerosol generating article 100 or internal air to be exhausted from the aerosol generating article 100. The multiple openings may be formed at positions corresponding to the multiple openings 160 of the cooling section 130.

[0136] The packaging 170 can be made of ordinary packaging paper. For example, the packaging 170 can be porous packaging paper or non-porous packaging paper.

[0137] The package 170 may include a predetermined material. Here, the predetermined material may be silicon, but is not necessarily limited to it. For example, silicon exhibits properties such as heat resistance, oxidation resistance, resistance to various chemicals, water resistance, and electrical insulation. However, any material other than silicon may be used in the package 170 without limitation, as long as the material exhibits the aforementioned properties.

[0138] Additionally, the packaging 170 may include a non-combustible material to prevent the aerosol generating article 100 according to this embodiment from burning. For example, the aerosol generating article 100 may burn when the tobacco medium portion 110 is heated by the heater 370 of the aerosol generating apparatus 300. Specifically, the aerosol generating article 100 may burn when the temperature rises to a temperature higher than the ignition point of any of the materials included in the tobacco medium portion 110.

[0139] According to this embodiment, the packaging 170 can prevent the aerosol generating device 300 from being contaminated by substances generated by the aerosol generating article 100. When a user smokes, liquid substances may be generated in the aerosol generating article 100. For example, when the aerosol generated by the aerosol generating article 100 is cooled by outside air, liquid substances such as moisture may be generated.

[0140] When the packaging 170 packages the tobacco medium portion 110, the cooling portion 130, and the filter portion 150, it prevents the liquid substances generated in the aerosol generating article 100 from leaking outside the aerosol generating article 100. Therefore, it prevents the interior of the aerosol generating device 300 from being contaminated by the liquid substances generated by the aerosol generating article 100.

[0141] The packaging 170 can define the outermost surface of the aerosol-generating article 100, allowing the shape of the aerosol-generating article 100 to vary according to the shape of the packaging 170. For example, characters, patterns, symbols, images, etc., can be printed on the packaging 170. The characters, patterns, symbols, images, etc., printed on the packaging 170 can vary, allowing the aerosol-generating article 100 to provide various visual information.

[0142] In the following, an aerosol generating apparatus in which an aerosol generating article according to an embodiment of the present disclosure is inserted will be described.

[0143] Figure 19 This is a schematic diagram showing the configuration of an aerosol generating apparatus in which an aerosol generating article according to an embodiment of the present disclosure is inserted.

[0144] refer to Figure 19 The aerosol generating apparatus 300 according to this embodiment may include a heater 370, a power supply 330, a controller 310, and an aerosol generator 350. Here, those skilled in the art related to this embodiment will understand that, in addition to... Figure 19 In addition to the components shown, other common components may also be included in the aerosol generating apparatus 300.

[0145] At the same time, Figure 19 In the diagram, the power supply unit 330, controller 310, and aerosol generator 350 are shown arranged in a row. However, the arrangement of the power supply unit 330, controller 310, and aerosol generator 350 can be modified if needed. Additionally, in Figure 19 The diagram shows an aerosol generator 350, but it may not include an aerosol generator 350, and the aerosol generating article 100 may be operated by heating only by the heater 370.

[0146] The aerosol generating article 100 can be inserted into the aerosol generating apparatus 300. The aerosol generating article 100 can be inserted and fixed to the aerosol generating apparatus 300 using a fixing device. In this embodiment, the tobacco medium portion 110 of the aerosol generating article 100 can be used as a fixing device. However, other fixing devices may be included besides the tobacco medium portion 110.

[0147] Heater 370 can heat aerosol generating article 100. When heater 370 is heated by electricity supplied from power supply unit 330, heater 370 can transfer heat to aerosol generating article 100.

[0148] Heater 370 may be a resistance heater. Heater 370 may include conductive rails. When current flows through the conductive rails via power supplied from power supply 330, heater 370 can heat aerosol generating article 100.

[0149] As another example, heater 370 may be an induction heater. Heater 370 may include a conductive coil for heating aerosol generating article 100 by induction heating method, and aerosol generating article 100 may include a base that may be heated by the induction heater.

[0150] exist Figure 19 In this design, heater 370 is shown disposed outside aerosol generating article 100, but is not necessarily limited thereto. Heater 370 may include at least one of tubular heating elements, plate heating elements, needle heating elements, and rod heating elements. Depending on the shape of at least one heating element included in heater 370, heater 370 may heat the interior or exterior of aerosol generating article 100, or may heat both the interior and exterior of aerosol generating article 100 simultaneously.

[0151] The power supply unit 330 can supply power for use in the aerosol generating apparatus 300. For example, the power supply unit 330 can supply power for heating the heater 370 and for operating the controller 310. In addition, the power supply unit 330 can supply power for operating the display, sensors, motors, etc. of the aerosol generating apparatus 300.

[0152] The controller 310 can control the overall operation of the aerosol generating device 300. Specifically, the controller 310 can control the operation of other components, including the power supply unit 330 and the aerosol generator 350. Furthermore, the controller 310 can determine whether the aerosol generating device 300 is in an operable state by checking the status of each component in the aerosol generating device 300.

[0153] The aerosol generator 350 generates an aerosol by heating a liquid composition. The generated aerosol can pass through the aerosol generating article 100 and be delivered to the user. In other words, the aerosol generated by the aerosol generator 350 can be introduced into the tobacco medium portion 110 of the aerosol generating article 100.

[0154] The aerosol generator 350 may include, but is not limited to, a liquid reservoir, a liquid delivery device, and a heating element. For example, the liquid reservoir, the liquid delivery device, and the heating element may be included as separate modules in the aerosol generating apparatus 300.

[0155] The liquid reservoir can store a liquid composition. For example, the liquid composition may be a liquid comprising tobacco-containing materials having volatile tobacco flavoring components, or a liquid comprising non-tobacco materials. The liquid reservoir may be manufactured to be attached to or detached from the aerosol generating apparatus 300, or may be manufactured integrally with the aerosol generating apparatus 300.

[0156] When the aerosol generator 350 according to an embodiment of the present disclosure includes a liquid containing non-tobacco materials, the liquid composition stored in the liquid reservoir included in the aerosol generator 350 may not contain nicotine, and the aerosol generated by the aerosol generator 350 may be introduced into the tobacco medium portion 110 without containing nicotine. In this case, the nicotine-free aerosol can pass through the tobacco medium portion 110 and adsorb nicotine, and the aerosol that has passed through the tobacco medium portion 110 may contain nicotine.

[0157] The liquid composition included in the aerosol generator 350 may include water, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruit flavoring ingredients. Flavorings may include ingredients that provide a variety of scents or tastes to the user. The vitamin mixture may be a mixture of at least one of vitamins A, B, C, and E, but is not limited to. Additionally, the liquid composition may contain aerosol forming agents such as glycerin and propylene glycol.

[0158] While this disclosure has been shown and described with reference to exemplary embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made therein without departing from the spirit and scope of this disclosure as defined by the appended claims. Therefore, the scope of this disclosure is defined not by the detailed description thereof but by the appended claims, and all differences within that scope shall be construed as included in this disclosure.
