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 of dicotyledonous plants, but in recent times it has come to refer to a product manufactured for smoking, with tobacco leaves wrapped in cigarette paper and a filter on one side. There are thousands of varieties of such cigarettes available around the world, and they are sold in a variety of patterns and shapes.

[0003] Among these, in the case of combustible tobacco, which is smoked by lighting it, such as rolling cigarettes, cigars, and pipe tobacco, the smoke contains not only aerosols containing nicotine, but also large amounts of other components such as tar, nitroamines, hydrocarbons, and carbon monoxide.

[0004] As an alternative to the drawbacks of the combustion cigarette, a method of generating aerosol by heating an aerosol-generating substance in a cigarette, rather than by burning a cigarette, is widely used and in increasing demand, and as a result, research on heat-not-burn cigarettes or heat-not-burn aerosol generating devices is actively being conducted.

[0005] Specifically, aerosol generating devices have a similar form to conventional combustion cigarettes, and generate mainstream smoke containing aerosols by heating the aerosol-generating material in the heated cigarette using methods such as a heater or ultrasonic vibration. This has the advantage of minimizing the emission of components such as tar while satisfying the smoker's desire to smoke, and is creating a new market that replaces conventional combustion cigarettes.

[0006] However, when a heated cigarette is heated by an aerosol generating device, high-temperature mainstream smoke is generated inside the cigarette, and such high-temperature aerosol may be transferred to the user. The high-temperature mainstream smoke may cause inconvenience or burns to the user. Alternatively, the heated cigarette may not be heated evenly, preventing the aerosol from moving smoothly inside the cigarette. Summary of the Invention [Problem to be solved by the invention]

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

[0008] Another object of the present disclosure is to provide an aerosol production article that can uniformly heat the tobacco medium to form a rich aerosol. [Means for solving the problem]

[0009] According to one embodiment, an aerosol product can be provided that includes a tobacco medium portion, a filter portion spaced apart from the tobacco medium portion, a cooling portion disposed between the tobacco medium portion and the filter portion, and a heat transfer portion surrounding at least a portion of the cooling portion. Effect of the Invention

[0010] As described above, the aerosol product according to one aspect of the present disclosure can prevent the user from feeling inconvenienced or being burned by hot mainstream smoke.

[0011] In addition, the tobacco medium portion can be uniformly heated to form abundant aerosol. [Brief description of the drawings]

[0033] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. At this time, it should be noted that in the accompanying drawings, the same components are denoted by the same reference numerals as much as possible. In addition, detailed descriptions of known functions and configurations that may obscure the gist of the present disclosure will be omitted. For the same reason, some components are exaggerated, omitted, or illustrated in a schematic manner in the accompanying drawings.

[0034] The aerosol product according to the first embodiment of the present disclosure will now be described.

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

[0036] 1 to 4, an aerosol product 100 according to an embodiment of the present disclosure may include a tobacco medium portion 110, a cooling portion 130, a filter portion 150, and a wrapper 170. In addition to the components shown in FIGS. 1 to 4, a person skilled in the art related to this embodiment may understand that other general components may be further included in the aerosol product 100.

[0037] The aerosol product (100) according to this embodiment can be inserted into an aerosol generating device (300, see Figs. 22 and 23) described below and heated. When the aerosol product (100) is heated, mainstream smoke can be delivered to a user. The mainstream smoke can be an airflow flowing from upstream to downstream inside the aerosol product (100). Here, upstream can refer to the tobacco medium part (110) side, and downstream can refer to the filter part (150) side. A user of the aerosol product (100) can inhale the mainstream smoke through the downstream end of the aerosol product (100).

[0038] The aerosol product 100 may have a cylindrical shape. In this case, the diameter of the aerosol product 100 may be 4.7 mm to 9.9 mm. The tobacco medium section 110, the cooling section 130, and the filter section 150 may also have a cylindrical shape with a diameter of 4.7 mm to 9.9 mm.

[0039] Additionally, the aerosol product (100) may have a length of 31 mm to 60 mm. The length of the tobacco medium portion (110) may be 17 mm to 30 mm. The length of the cooling portion (130) may be 4 mm to 10 mm, and the length of the filter portion (150) may be 10 mm to 20 mm.

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

[0041] The tobacco medium portion 110, located upstream of the aerosol producing article 100, may contain a tobacco medium for generating 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 a cigarette.

[0042] When the aerosol product (100) of this embodiment is heated by an aerosol generating device (300, see FIG. 23) described below, and the aerosol generated by the aerosol generating device (300) flows into the inside of the aerosol product (100), nicotine can be adsorbed onto the surface of the aerosol and delivered to the user as the aerosol passes through the tobacco medium portion (110).

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

[0044] Nicotine salts can be formed by adding a suitable acid, including organic or inorganic acids, to nicotine. The acid for forming nicotine salts can be appropriately selected in consideration of the nicotine absorption rate in blood, the heating temperature of the heater, the flavor or taste, solubility, etc. For example, the acid for forming nicotine salts can 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, saccharic 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 prepared in various forms. For example, the tobacco medium can be prepared in a sheet or a strand. The tobacco medium can also be prepared in a cut tobacco form in which the tobacco sheet is cut into small pieces. The tobacco medium can also be prepared in a granular form containing tobacco.

[0046] 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 may have a bar shape having a cross section of various shapes.

[0047] In this case, the tobacco medium portion (110) can be produced by folding a tobacco sheet so as to create wrinkles into a cylindrical shape, or by forming tobacco strands, cut tobacco, or tobacco granules into a cylindrical shape.

[0048] When the tobacco medium portion (110) is made of a plurality of tobacco strands obtained by shredding a tobacco sheet, the tobacco medium portion (110) may be formed by combining a plurality of tobacco strands in the same direction (parallel) or randomly. Specifically, the tobacco medium portion (110) may be formed by combining a plurality of tobacco strands to form a plurality of longitudinal channels through which the aerosol can pass. In this case, 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 generating material to increase the amount of atomization, for example, the aerosol generating material 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 material to add flavor to the aerosol. For example, the tobacco medium portion (110) may contain other additives such as flavoring agents, humectants, and / or organic acids. In addition, a flavoring liquid such as menthol or a humectant may be added to the tobacco medium portion (110) by being sprayed into 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, etc. Also, the humectant may include glycerin or propylene glycol, etc.

[0052] Meanwhile, in this embodiment, the tobacco medium portion (110) may be composed of at least one segment. For example, the tobacco medium portion (110) may be composed of one segment or two segments. Specifically, the tobacco medium portion (110) according to this embodiment shown in Figure 4 may be composed of one segment. Also, as shown in Figures 10 and 11, the tobacco medium portion (110) may be composed of two segments.

[0053] 4, the tobacco medium portion (110) of this embodiment may consist of one segment. The segment of the tobacco medium portion (110) may be filled with the tobacco medium. That is, in this embodiment, the tobacco medium portion (110) may consist of one segment filled with the tobacco medium.

[0054] In this case, the segment may be prepared by folding a tobacco sheet into a cylindrical shape as described above, or by forming a tobacco strand, cut tobacco, or tobacco granules into a cylindrical shape, and the segment may further include an aerosol generating material and / or a flavoring material capable of increasing the amount of atomization.

[0055] Also, the segment of the tobacco medium portion (110) may be heated by coupling with a heating portion (370, see FIG. 22) of the aerosol generating device (300) which heats the aerosol product (100). In FIG. 22, the heating portion (370) may be inserted inside the aerosol product (100) to heat the tobacco medium portion (110).

[0056] On the other hand, in the variation illustrated in Figures 10 and 11, the tobacco medium portion (110) may consist of two segments, one of which may contain the tobacco medium and the other of which may not contain the tobacco medium.

[0057] 10 and 11, the tobacco medium section (110) may include a first tobacco segment (111) and a second tobacco segment (113). The first tobacco segment (111) is a segment filled with tobacco medium and may be the same as the segment of the tobacco medium section (110) of FIG. 4 described above.

[0058] The second tobacco segment (113) is located at the upstream end of the aerosol product (100) and can prevent the first tobacco segment (111) containing the tobacco medium from escaping to the outside of the aerosol product (100). That is, the tobacco medium portion (110) of this modified example can be arranged in the order of the second tobacco segment (113) and the first tobacco segment (111) from the upstream side.

[0059] The second tobacco segment (113) can prevent impurities from flowing into the first tobacco segment (111) from the outside and can prevent the aerosol liquefied during smoking from flowing into the aerosol generating device (300, see Figure 22 or Figure 23).

[0060] Additionally, when the aerosol product (100) is inserted into the aerosol generation device (300), the second tobacco segment (113) can support the aerosol product (100) so that the aerosol product (100) is fixed to the aerosol generation device (300).

[0061] The second tobacco segment (113) can be a cellulose acetate filter. For example, the second tobacco segment (113) can be made of cellulose acetate tow with a plasticizer, such as triacetin, and the cellulose acetate tow can include an aerosol-forming material.

[0062] The aerosol-forming substance contained in the second tobacco segment (113) may exclude nicotine. For example, the second tobacco segment (113) 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-forming substance contained in the second tobacco segment (113) is not necessarily limited thereto. For example, the second tobacco segment (113) may include a mixture of glycerin and propylene glycol in a ratio of approximately 8:2. However, the mixture ratio is not limited to the above.

[0063] In addition, the second tobacco segment (113) may contain other additives, such as flavoring agents, humectants, and / or organic acids. However, the material and type of the second tobacco segment (113) are not necessarily limited thereto and may be varied within the scope of those skilled in the art.

[0064] The second tobacco segment (113) may have a through hole formed therein through which the aerosol flows from the outside to form mainstream smoke inside the aerosol product (100). The through hole formed in the second tobacco segment (113) may have a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto and may have various cross-sectional shapes.

[0065] On the other hand, if the second tobacco segment (113) comprises a crimped sheet impregnated with an aerosol-forming material, the second tobacco segment (113) may not be perforated.

[0066] When a portion of the aerosol production article (100) is inserted into the aerosol generation device (300, see FIG. 23), the aerosol generated in the aerosol generation device (300) flows into the inside of the aerosol production article (100) through the second tobacco segment (113), and the aerosol forms mainstream smoke inside the aerosol production article (100) and can be delivered to a user. Also, the aerosol generated inside the second tobacco segment (113) containing the aerosol generating substance can form mainstream smoke and be delivered to a user.

[0067] At this time, the tobacco medium part (110) may be heated by the heating part (390) of the aerosol generating device (300) being disposed around the tobacco medium part (110). The heat transfer part (190) may surround the first cooling segment (131) of the cooling part (130), or may surround not only the first cooling segment (131) but also at least a part of the second cooling segment (133). A detailed description of this will be given later.

[0068] 1 to 4 again, in this embodiment, the filter portion 150 may be located at a downstream end spaced apart from the tobacco medium portion 110. The filter portion 150 may filter at least one of the substances contained in mainstream smoke.

[0069] 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 necessarily limited thereto, and may be changed within the range that can be adopted by those skilled in the art.

[0070] The filter portion (150) may be cylindrical, however, the shape of the filter portion (150) is not necessarily limited thereto, and may have various shapes corresponding to the shape of the tobacco medium portion (110).

[0071] The filter portion 150 may be fabricated to emit a flavor. For example, a flavoring liquid may be sprayed onto the filter portion 150, or a separate fiber onto which the flavoring liquid is applied may be included inside the filter portion 150.

[0072] Alternatively, the filter portion (150) may include at least one capsule (not shown). The capsule may generate a flavor or generate an aerosol. For example, the capsule may have a structure in which a liquid containing a flavoring is enveloped in a membrane. In this case, the capsule may have a spherical or cylindrical shape, but the shape of the capsule is not necessarily limited thereto.

[0073] 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) to cool the high-temperature aerosol passing through the inside. 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 can be delivered to the user through the filter unit (150). This makes it possible to prevent the high-temperature aerosol from being directly delivered to the user.

[0074] In this embodiment, the cooling unit 130 may be composed of a first cooling segment 131 and a second cooling segment 133. That is, the cooling unit 130 may be composed of two segments. However, the cooling unit 130 is not necessarily limited to this and may be composed of two or more segments.

[0075] The first cooling segment (131) and the second cooling segment (133) may be disposed adjacent to the tobacco medium portion (110) in this order. Specifically, the first cooling segment (131) may be disposed in contact with the tobacco medium portion (110), and the second cooling segment (133) may be disposed between the first cooling segment (131) and the filter portion (150). That is, in this embodiment, the tobacco medium portion (110), the first cooling segment (131), the second cooling segment (133), and the filter portion (150) may be disposed in this order from the upstream side.

[0076] The first cooling segment (131) not only cools the aerosol coming out of the tobacco medium portion (110) but also prevents the tobacco medium of the tobacco medium portion (110) from escaping to the second cooling segment (133). For example, when a heating portion (370, see FIG. 22) for heating the aerosol product (100) is inserted into the tobacco medium portion (110), the tobacco medium in the tobacco medium portion (110) may escaping and move to the second cooling segment (133). The first cooling segment (131) is disposed between the tobacco medium portion (110) and the second cooling segment (133), thereby preventing the tobacco medium in the tobacco medium portion (110) from escaping to the second cooling segment (133).

[0077] The first cooling segment (131) may be made of cellulose acetate tow with a plasticizer, such as triacetin, added thereto, and an aerosol generating material may be included in the cellulose acetate tow.

[0078] The first cooling segment (131) 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 generating material included in the first cooling segment (131) is not necessarily limited thereto. For example, the first cooling segment (131) may include a material in which glycerin and propylene glycol are mixed in a ratio of about 8:2. However, the mixture ratio is not limited to the above.

[0079] In addition, the first cooling segment (131) may contain other additives such as flavorings, humectants, and / or organic acids. However, the material and type of the first cooling segment (131) are not necessarily limited thereto and may be changed within the range that can be adopted by those skilled in the art.

[0080] The first cooling segment (131) may have a through hole for allowing the aerosol to flow from the tobacco medium portion (110) to form a main flow inside the aerosol product (100). The through hole formed in the first cooling segment (131) may have a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto and may have various cross-sectional shapes.

[0081] The second cooling segment (133) is disposed between the first cooling segment (131) and the filter portion (150) and is capable of further cooling the aerosol that has passed through the first cooling segment (131).

[0082] The second cooling segment (133) may have a tubular shape through which the aerosol can pass. Specifically, the second cooling segment (133) may have a through hole (T) formed therein. The through hole (T) is a space formed in the center of the second cooling segment (133), through which the aerosol can move from the tobacco medium portion (110) to the filter portion (150). In this embodiment, the diameter of the through hole (T) of the second cooling segment (133) may be larger than the through hole of the first cooling segment (131). However, the diameter of the through hole (T) of the second cooling segment (133) is not necessarily limited thereto, and the diameter of the through hole (T) of the second cooling segment (133) may be the same as or smaller than the through hole of the first cooling segment (131).

[0083] The high-temperature aerosol flowing into the inlet of the second cooling segment (133) may be cooled as it passes through the through hole (T) of the second cooling segment (133). In the process of cooling the aerosol, a portion of the heat contained in the aerosol may be discharged to the outside through the main body of the second cooling segment (133). At this time, a separate member containing PLA (polylactic acid) may be disposed inside the through hole (T) of the second cooling segment (133). For example, the inside of the through hole (T) may be at least partially filled with PLA.

[0084] The body of the second cooling segment (133) may be made by adding a plasticizer such as triacetin to cellulose acetate tow. Alternatively, the body of the second cooling segment (133) may be made of a slip sheet composed of multiple papers. For example, the body may be a slip sheet composed of an outer paper, a middle paper, and an inner paper, but is not necessarily limited to this, and may be a single paper. In this case, a cooling substance may be coated on the inside of the slip sheet, and a cooling film may be attached. Here, the cooling substance or the cooling film may include various substances having high thermal efficiency. However, the material and type of the body of the second cooling segment (133) are not necessarily limited to this and may be changed within the range that can be adopted by a person skilled in the art.

[0085] When the main body of the second cooling segment (133) 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 main body may be 9 to 12.

[0086] In addition, the cross section of the filament constituting the main body of the second cooling segment (133) may be Y-shaped. Here, the filament may refer to a long fiber connected in a single strand constituting the cellulose acetate tow.

[0087] Meanwhile, the main body of the second cooling segment (133) may contain other additives such as flavoring agents, humectants, and / or organic acids. In this case, the flavoring agents 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. Also, the humectant may include glycerin or propylene glycol.

[0088] The body of the second cooling segment (133) may have a doughnut-shaped cross section due to the through hole (T). In this case, the inner diameter of the body may be 2 mm or more. Preferably, the inner diameter of the body may be 3.8 to 4.2 mm.

[0089] At this time, a plurality of openings 160 may be formed in the body of the second cooling segment 133 so that outside air can flow in and internal air can flow out. The plurality of openings 160 may be formed spaced apart from one another in the circumferential direction of the body.

[0090] In this embodiment, a plurality of openings 160 may be disposed on the inlet side of the second cooling segment 133, i.e., adjacent to the first cooling segment 131. The aerosol passing through the second cooling segment 133 can be further cooled by the outside air flowing in through the plurality of openings 160. This allows the aerosol flowing in the filter unit 150 to be cooled again, thereby preventing the high-temperature aerosol from being inhaled into the mouth of the user.

[0091] In this embodiment, the multiple openings (160) are described as being arranged on the inlet side of the second cooling segment (133), however, the location of the multiple openings (160) is not necessarily limited thereto, and the multiple openings (160) may be arranged at other locations of the second cooling segment (133), for example, on the outlet side of the second cooling segment (133) or in a central region of the second cooling segment (133).

[0092] According to this embodiment, the heat transfer unit 190 may be disposed to surround at least a portion of the cooling unit 130. The heat transfer unit 190 may heat or cool the aerosol inside the aerosol product 100. A specific process in which the heat transfer unit 190 heats or cools the aerosol will be described below with reference to FIGS. 5 and 6.

[0093] The heat transfer section (190) surrounds the outer periphery of the cooling section (130), and may surround only a portion of the cooling section (130) along the length of the cooling section (130) or may surround the entire cooling section (130).

[0094] Specifically, as shown in FIG. 4, in this embodiment, the heat transfer part (190) may surround the entire outer circumferential surface of the first cooling segment (131) of the cooling part (130).

[0095] Alternatively, in the variation of FIG. 7, the heat transfer portion (190) may surround only a portion of the first cooling segment (131).

[0096] 8, the heat transfer portion (190) may surround the entire first cooling segment (131) and only a portion of the second cooling segment (133). In this case, the heat transfer portion (190) may be disposed up to just before the position where the opening (160) of the second cooling segment (133) is formed so as not to cover the opening (160).

[0097] 9, the heat transfer unit (190) may entirely surround the first cooling segment (131) and the second cooling segment (133). That is, the heat transfer unit (190) may be disposed so as to entirely surround the cooling unit (130). In this case, the heat transfer unit (190) may have an opening formed at a position corresponding to the opening (160) of the second cooling segment (133).

[0098] In this embodiment, the heat transfer section (190) may extend from the inlet of the cooling section (130) that contacts the tobacco medium section (110). As shown in FIG. 4, the heat transfer section (190) may be disposed at the position where the tobacco medium section (110) and the cooling section (130) contact each other, i.e., from the inlet of the cooling section (130) to surround the cooling section (130). Thus, while the tobacco medium section (110) is heated by the heating section (370), the heat transfer section (190) can keep the downstream side of the tobacco medium section (110) warm so that it is heated to the same temperature as the other sections of the tobacco medium section (110). In addition, the heat transfer section (190) can further cool the aerosol moving inside the cooling section (130). A specific process for this will be described later.

[0099] Hereinafter, a process in which the heat transfer part 190 heats or cools the aerosol in the aerosol product 100 according to the present embodiment will be described with reference to FIGS.

[0100] Figure 5 is a diagram illustrating the process in which a heating unit is inserted into an aerosol product according to the first embodiment of the present disclosure to heat the tobacco medium unit, and Figure 6 is a diagram illustrating the process in which a heating unit is inserted into a conventional aerosol product to heat the tobacco medium unit.

[0101] The heat transfer section (190) according to this embodiment can keep the aerosol warm while heating the tobacco medium section (110) before the user inhales the mainstream smoke, and can cool the aerosol while the user inhales the mainstream smoke.

[0102] The process in which a user inhales mainstream smoke using the aerosol production product (100) of this embodiment can be divided into a process in which the heating section (370) of the aerosol generating device (300, see FIG. 22) inserted into the tobacco medium section (110) first heats the tobacco medium section (110) to generate an aerosol, and then, when the tobacco medium section (110) reaches a predetermined temperature and an aerosol is generated, the user inhales mainstream smoke through the mouth.

[0103] 5, while the heating section (370) first heats the tobacco medium section (110), the heat transfer section (190) can keep the downstream side (P) of the tobacco medium section (110) adjacent to the cooling section (130) warm. Thus, while the first tobacco medium section (110) is being heated, the heat transfer section (190) can heat the entire section of the tobacco medium section (110) at a uniform temperature.

[0104] The heat transfer section (190) is in the form of a metal foil and can block heat generated from the heating section (370) at the downstream side (P) of the tobacco medium section (110) from being released to the outside through the body of the cooling section (130). Since the heat transfer section (190) blocks heat from being released to the outside, it is possible to prevent the temperature of the downstream side (P) of the tobacco medium section (110) from becoming too low, unlike in the past.

[0105] 6 illustrates a process in which a conventional aerosol product (100) is heated by a heating section (370), and while the heating section (370) first heats the tobacco medium section (110), heat inside the downstream side (P) of the tobacco medium section (110) can be released through the adjacent cooling section (130) (see FIG. 6(A)). As a result, the temperature of the downstream side (P) of the tobacco medium section (110) becomes lower than the temperature of the other sections (M) of the tobacco medium section (110) (see FIG. 6(B)).

[0106] The heating section (370) is configured by surrounding an electric resistance heater (H) with a ceramic material (C), and since the high temperature of the heating section (370) may melt the cooling section (130, the end of the heating section (370) cannot be inserted close to the cooling section (130). That is, the end of the heating section (370) cannot be inserted to the end of the tobacco medium section (110). Since the end of the heating section (370) cannot be inserted to the end of the tobacco medium section (110), the downstream section (P) of the tobacco medium section (110) is heated less than the other sections (M) and the heat inside the downstream section (P) is released through the adjacent cooling section (130), so that the temperature of the downstream section (P) of the tobacco medium section (110) may be lower than the temperature of the other sections (M).

[0107] If the temperature of the downstream side (P) of the tobacco medium section (110) is low, the aerosol generated in the other sections (M) of the tobacco medium section (110) is liquefied on the downstream side (P) of the tobacco medium section (110) where the temperature is low, and this hinders the flow of the aerosol on the downstream side (P) of the tobacco medium section (110). In other words, the aerosol generated in the tobacco medium section (110) cannot flow smoothly to the cooling section (130).

[0108] Therefore, in this embodiment, the heat transfer section (190) keeps the downstream side of the tobacco medium section (110) warm while the tobacco medium section (110) is being heated initially, so that the aerosol generated in the tobacco medium section (110) can flow smoothly to the cooling section (130) without being stagnant on the downstream side of the tobacco medium section (110).

[0109] Meanwhile, when the tobacco medium part (110) reaches a predetermined temperature and aerosol is generated, and the user inhales mainstream smoke through his / her mouth, the heat transfer part (190) can further cool the high-temperature aerosol moving through the cooling part (130). When the high-temperature aerosol is cooled while passing through the cooling part (130), the heat transfer part (190) surrounding the cooling part (130) dissipates the heat to the outside of the cooling part (130), thereby further cooling the high-temperature aerosol. This can prevent the high-temperature aerosol from being directly transferred to the user.

[0110] At this time, the heat transfer part (190) may be in the form of a metal foil. That is, the heat transfer part (190) may be in the form of a thin metal plate surrounding the cooling part (130). The metal heat transfer part (190) is disposed on the outer circumferential surface of the cooling part (130) adjacent to the tobacco medium part (110), thereby making it possible to heat or cool the aerosol during smoking.

[0111] The heat transfer part 190 may include a metal material. For example, the heat transfer part 190 may include at least one of aluminum, copper, ferrite, and martensite. Preferably, the heat transfer part 190 may be in the form of a metal foil including aluminum. However, the heat transfer part 190 is not necessarily limited thereto, and various materials having high thermal conductivity may be used.

[0112] In this embodiment, the heat transfer unit (190) may be in the form of a metal plate and may be disposed around the outer periphery of the cooling unit (130) (see FIG. 1). Alternatively, as shown in the modified examples of FIGS. 12 to 14, the heat transfer unit (190) may be in the form of a plurality of metal bands and may be disposed around the outer periphery of the cooling unit (130). The plurality of metal bands constituting the heat transfer unit (190) may be disposed spaced apart from one another.

[0113] 12, the heat transfer unit 190 may be in the form of metal bands spaced apart from one another and surround the outer periphery of the first cooling segment 131 of the cooling unit 130. In this case, the heat transfer unit 190 in the form of a plurality of metal bands may be arranged parallel to the extension direction of the cooling unit 130. That is, the plurality of metal bands may be arranged parallel to the cooling unit 130.

[0114] 13, the heat transfer unit 190 is arranged in the form of a plurality of metal bands, which may be arranged at an angle to the extension direction of the cooling unit 130. That is, unlike the above-described Fig. 12, the plurality of metal bands may be arranged not parallel to the extension direction of the cooling unit 130. Specifically, the plurality of metal bands may be arranged in a spiral shape around the outer circumferential surface of the cooling unit 130.

[0115] Referring to FIG. 14, the heat transfer portion (190) is arranged in the form of a plurality of metal bands and is arranged parallel to the extension direction of the cooling portion (130), however, the metal bands may be arranged in a serpentine form.

[0116] Referring again to Fig. 4, the aerosol product (100) according to this embodiment may be wrapped by a wrapper 170. The wrapper (170) may surround the tobacco medium section (110), the cooling section (130) and the filter section (150) which are arranged in a row. In this manner, when the wrapper (170) surrounds the tobacco medium section (110), the cooling section (130) and the filter section (150), the aerosol product (100) may maintain its inherent cylindrical shape.

[0117] The wrapper (170) may surround the entire outer periphery of the tobacco medium section (110), the cooling section (130) and the filter section (150).

[0118] Each of the tobacco medium portion (110), the cooling portion (130) and the filter portion (150) constituting the aerosol product (100) according to this embodiment may be individually wrapped in a separate wrapper (not shown). When the tobacco medium portion (110) includes a plurality of segments, each of the plurality of segments may be wrapped in a separate wrapper, or the plurality of segments may be wrapped in a single wrapper. In this manner, when the tobacco medium portion (110), the cooling portion (130) and the filter portion (150) are individually wrapped, the individually wrapped tobacco medium portion (110), the cooling portion (130) and the filter portion (150) may be rewrapped in a wrapper (170).

[0119] The wrapper 170 may have a number of openings (not shown) formed therein to allow outside air to flow into the aerosol product 100 and for internal air to flow out of the aerosol product 100. The number of openings may be formed at locations corresponding to the number of openings 160 in the cooling section 130.

[0120] The wrapper (170) may be made of any conventional wrapping paper. For example, the wrapper (170) may be a porous wrapping paper or a non-porous wrapping paper.

[0121] The wrapper (170) may include a predetermined material. Here, the predetermined material may be, but is not limited to, silicon. For example, silicon may have properties such as heat resistance, which is less susceptible to change with temperature, oxidation resistance, resistance to various chemicals, water repellency, and electrical insulation. However, any material having the above-mentioned properties other than silicon may be applied to the wrapper (170) without any restrictions.

[0122] In addition, since the wrapper (170) contains a non-flammable material, it is possible to prevent the aerosol product (100) of this embodiment from being burned. For example, when the tobacco medium portion (110) is heated by the heating portion (370) of the aerosol generating device (300), the aerosol product (100) may be burned. Specifically, when 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 be burned.

[0123] The wrapper 170 can prevent the aerosol generating device 300 from being contaminated by the substances generated by the aerosol generating product 100 according to the present embodiment. When smoking, a liquid substance can be generated within the aerosol generating product 100. For example, a liquid substance such as water can be generated by cooling the aerosol generated by the aerosol generating product 100 with the outside air.

[0124] The wrapper 170 wraps the tobacco medium portion 110, the cooling portion 130, and the filter portion 150, thereby preventing the liquid substance generated in the aerosol product 100 from leaking out of the aerosol product 100. This prevents the inside of the aerosol generating device 300 from being contaminated by the liquid substance generated in the aerosol product 100.

[0125] 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, the wrapper 170 can be printed with text, patterns, symbols, images, etc., and the text, patterns, symbols, images, etc. printed on the wrapper 170 can be changed, allowing the aerosol product 100 to provide different visual information.

[0126] The following describes an aerosol product according to a second embodiment of the present disclosure and its modified example.

[0127] FIG. 15 is a cross-sectional view of an aerosol product according to the second embodiment of the present disclosure, FIGS. 16 to 18 show modified examples of the tobacco medium portion of the aerosol product according to the second embodiment of the present disclosure, and FIG. 19 shows a modified example of the filter portion of the aerosol product of FIG. 16.

[0128] Referring to FIG. 15, the aerosol product of the second embodiment has the same structure as the aerosol product of the first embodiment (100) except for the tobacco medium section (110) and the cooling section (130), so a duplicated description of the same components will be omitted.

[0129] According to this embodiment, as shown in Fig. 15, the cooling unit (130) may be configured as one segment, unlike the cooling unit (130) of the first embodiment. That is, while the cooling unit (130) of the first embodiment is configured as two segments, the cooling unit (130) of this embodiment may be configured as one segment.

[0130] In this case, the cooling portion 130 may be configured with the same shape and material as the second cooling segment 133 of the first embodiment.

[0131] The cooling section (130) may have a tubular shape through which the aerosol can pass. Specifically, the cooling section (130) may have a through hole (T) formed therein. The through hole (T) is a space formed in the center of the cooling section (130), through which the aerosol can move from the tobacco medium section (110) to the filter section (150).

[0132] The high-temperature aerosol flowing into the inlet of the cooling unit 130 may be cooled as it passes through the through hole T of the cooling unit 130. In the process of cooling the aerosol, a portion of the heat contained in the aerosol may be discharged to the outside through the main body of the cooling unit 130.

[0133] The body of the cooling section 130 may be made of cellulose acetate tow with a plasticizer such as triacetin added thereto, or may be made of a laminated paper made up of multiple papers. The body of the cooling section 130 may contain other additives such as flavoring agents, humectants, and / or organic acids.

[0134] In this embodiment, the heat transfer section (190) may be disposed so as to surround the outer circumferential surface of the cooling section (130). As in the first embodiment, the heat transfer section (190) may extend from the inlet of the cooling section (130) adjacent to the tobacco medium section (110). In this case, the heat transfer section (190) may extend up to the front of the opening (160) of the cooling section (130). However, the heat transfer section (190) is not necessarily limited thereto, and may be disposed so as to surround a part or the whole of the cooling section (130).

[0135] Meanwhile, in this embodiment, the tobacco medium portion 110 may be formed of one segment containing a tobacco medium, similar to the first embodiment described above. Here, the tobacco medium portion 110 may have the same shape and material as the tobacco medium portion 110 of the first embodiment described above.

[0136] 16 to 18 show modified examples of the tobacco medium portion (110) of this embodiment, in which the tobacco medium portion (110) may be made up of two segments.

[0137] Referring to FIG. 16, the tobacco medium part (110) may include a first tobacco segment (111) and a second tobacco segment (113). The first tobacco segment (111) may be made of the same material and shape as the tobacco medium part (110) of the first embodiment described above. For example, the first tobacco segment (111) includes a tobacco medium, which may be made into a sheet or a strand. The tobacco medium may also be made into shredded tobacco, which is a tobacco sheet cut into small pieces. The tobacco medium may also be made into a granular form containing tobacco.

[0138] Additionally, when the aerosol product (100) is inserted into the aerosol generation device (300), the second tobacco segment (113) can support the aerosol product (100) so that the aerosol product (100) is fixed to the aerosol generation device (300).

[0139] The second tobacco segment (113) can be a cellulose acetate filter. For example, the second tobacco segment (113) can be made of cellulose acetate tow with a plasticizer, such as triacetin, and the cellulose acetate tow can include an aerosol-forming material.

[0140] The aerosol-forming substance included in the second tobacco segment (113) may exclude nicotine. For example, the second tobacco segment (113) 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-forming substance included in the second tobacco segment (113) is not necessarily limited thereto.

[0141] In addition, the second tobacco segment (113) may contain other additives, such as flavoring agents, humectants, and / or organic acids. However, the material and type of the second tobacco segment (113) are not necessarily limited thereto and may be varied within the scope of those skilled in the art.

[0142] The second tobacco segment (113) may have a through hole formed therein through which the aerosol flows from the outside to form mainstream smoke inside the aerosol product (100). The through hole formed in the second segment (119) may have a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto and may have various cross-sectional shapes.

[0143] Referring to Figure 17, the tobacco medium portion (110) may include a first tobacco segment (111) and a third tobacco segment (115). The first tobacco segment (111) may be made of the same material and shape as the first tobacco segment (111) described above. Meanwhile, the third tobacco segment (115) is located in front of the first tobacco segment (111) and may include a crimped sheet impregnated with an aerosol-generating substance.

[0144] 18, the tobacco medium portion (110) may include a fourth tobacco segment (117) and a fifth tobacco segment (119). The fourth tobacco segment (117) and the fifth tobacco segment (119) may be in the form of a liquid nicotine solution or a nicotine salt impregnated into a crimped sheet.

[0145] 19 shows a modified example of the filter unit (150) of this embodiment, in which a recess (180) may be formed on the downstream side of the filter unit (150). The recess (180) is a structure in which the wrapper (170) surrounding the filter unit (150) extends further downstream than 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.

[0146] The recessed portion 180 can prevent traces of nicotine generated on the downstream end of the filter portion 150 from being easily exposed to the outside. Therefore, traces of nicotine generated on the filter portion 150 of the aerosol product 100 during smoking or after smoking is completed are not exposed to the outside, so that the aesthetic appearance may not be impaired.

[0147] Hereinafter, a process in which the heat transfer part 190 heats or cools the aerosol in the aerosol product 100 according to this embodiment will be described with reference to FIGS.

[0148] FIG. 20 is a diagram illustrating a process in which a conventional aerosol product is heated by a heating unit of an aerosol generating device, and FIG. 21 is a diagram illustrating a process in which an aerosol product according to a second embodiment of the present disclosure is heated by a heating unit of an aerosol generating device;

[0149] 20, in the past, the heating unit (370) was arranged to surround the entire tobacco medium unit (110) in order to uniformly heat the entire tobacco medium unit (110). The heating unit (370) was arranged up to the top of the aerosol generating device (300), which may cause the top of the aerosol generating device (300) to heat up to a high temperature, resulting in burns to the user.

[0150] 21, the heat transfer section (190) is disposed at the inlet side of the cooling section (130) adjacent to the tobacco medium section (110), and the heating section (390) of the aerosol generating device (300) may be disposed only up to a position spaced a certain distance (G) from the downstream side of the tobacco medium section (110). This prevents the top of the aerosol generating device (300) from being heated to a high temperature by the heating section (390), thereby preventing a user who comes into contact with the top of the aerosol generating device (300) from being burned.

[0151] The following describes an aerosol generating device into which an aerosol production product according to one embodiment of the present disclosure is inserted.

[0152] FIG. 22 is a schematic diagram of an aerosol generation device into which an aerosol product according to the first embodiment of the present disclosure is inserted, and FIG. 23 is a modified example of the aerosol generation device of FIG.

[0153] 22 and 23, the aerosol generating device 300 according to this embodiment may include a heating unit 370, 390, a power supply unit 330, a control unit 310, and an aerosol generating unit 350. In addition to the components shown in FIG. 22 and FIG. 23, it may be understood by a person skilled in the art related to this embodiment that the aerosol generating device 300 may further include other general-purpose components.

[0154] On the other hand, in Fig. 23, the power supply unit (330), the control unit (310), and the aerosol generating unit (350) are illustrated as being arranged in a line, but the arrangement of the power supply unit (330), the control unit (310), and the aerosol generating unit (350) may be changed as necessary. Also, as shown in Fig. 22, the aerosol generating unit (350) may be omitted, and the aerosol product (100) may be operated only by being heated by the heating unit (370).

[0155] An 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 part (110) of the aerosol production product (100) may correspond to the fixing means. However, in addition to the tobacco medium part (110), other fixing means may be added.

[0156] The heating units (370, 390) can heat the aerosol product (100). The heating units (370, 390) are heated by the power supplied from the power supply unit (330), and thus the heating units (370, 390) can transfer heat to the aerosol product (100).

[0157] The heating elements (370, 390) can be electrical resistive heaters. The heating elements (370, 390) can include an electrically conductive track, and the power source (330) can provide a current through the electrically conductive track, thereby allowing the heating elements (370, 390) to heat the aerosol product (100).

[0158] As another example, the heating units (370, 390) can be induction heaters. The heating units (370, 390) can include an electrically conductive coil for inductively heating the aerosol product article (100), and the aerosol product article (100) can include a susceptor that can be heated by the induction heater.

[0159] The power supply unit (330) supplies power used in the aerosol generating device (300). For example, the power supply unit (330) can supply power to heat the heating units (370, 390) and can supply power necessary for the control unit (310) to operate. The power supply unit (330) can also supply power necessary for the display, sensor, motor, etc. of the aerosol generating device (300) to operate.

[0160] The control unit (310) controls the overall operation of the aerosol generation device (300). Specifically, the control unit (310) controls the operation of the power supply unit (330) and other components included in the aerosol generation unit (350). The control unit (310) can also check the state of each component of the aerosol generation device (300) to determine whether the aerosol generation device (300) is in an operable state.

[0161] The aerosol generating unit (350) can heat the liquid composition to generate an aerosol, and the generated aerosol can be transmitted to a user through the aerosol product (100). In other words, the aerosol generated by the aerosol generating unit (350) can flow into the tobacco medium portion (110) of the aerosol product (100).

[0162] The aerosol generation unit (350) may include, but is not limited to, a liquid reservoir, a liquid transfer means, and a heating element. For example, the liquid reservoir, the liquid transfer means, and the heating element may be included in the aerosol generation device (300) as separate modules.

[0163] The liquid reservoir can store a liquid composition. For example, the liquid composition can be a liquid containing tobacco-containing substances including volatile tobacco aroma components, or a liquid containing non-tobacco substances. The liquid reservoir can be made removable or integral with the aerosol generating device (300).

[0164] 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) may flow into the tobacco medium unit (110) without containing nicotine. In this case, the aerosol not containing nicotine passes through the tobacco medium unit (110) and adsorbs nicotine, and the aerosol that has passed through the tobacco medium unit (110) contains nicotine.

[0165] The liquid composition contained in the aerosol generating unit (350) may include water, a solvent, ethanol, a plant extract, a flavor, a flavoring agent, or a vitamin mixture. The flavoring agent may include, but is not limited to, menthol, peppermint, spearmint oil, various fruit fragrance ingredients, and the like. The flavoring agent may include ingredients that can provide various flavors or tastes to the user. The vitamin mixture may include, but is not limited to, 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.

[0166] Although one embodiment of the present disclosure has been described above, a person having ordinary knowledge in the technical field may modify and change the present disclosure in various ways, such as by adding, changing, deleting or adding components, without departing from the concept of the present disclosure described in the claims, and this may also be considered to be within the scope of the rights of the present disclosure.
