Description

[0001] This application is a divisional application of a patent application No. 2019800101107, filed on January 18, 2019, with the title of "Aerosol-generating system". TECHNICAL FIELD

[0002] The present application provides a cigarette and an aerosol-generating system. BACKGROUND

[0003] Recently, the demand for alternative methods to overcome the shortcomings of a general cigarette is increasing. For example, the demand for a method of generating an aerosol by heating an aerosol-generating material in a cigarette, rather than generating an aerosol by burning a cigarette, is increasing.

[0004] In general, a pulp reconstituted tobacco sheet, which is a main raw material of a tobacco medium, is difficult to manufacture due to weak tension, and the tobacco medium also contains a large amount of a humectant, and thus is physically weak. In addition, the tobacco medium containing the humectant is sensitive to the humidity of the surrounding environment due to hydrophilicity, and thus it is difficult to control the air conditioning environment for manufacturing. The amount of the humectant that can be contained in the tobacco medium is also limited.

[0005] When the humectant is contained in a separately provided cartridge in addition to the tobacco medium, it is difficult to manage the humectant contained in the cartridge (expiration date, deterioration, etc.), and condensate is generated in a passage through which an aerosol generated in the cartridge moves, and thus contamination can occur.

[0006] Accordingly, research on a heated cigarette or a heated aerosol-generating device is actively being conducted. SUMMARY

[0007] Problems to be Solved by the Invention

[0008] An aerosol-generating system is provided. The aerosol-generating system can include a cigarette and an aerosol-generating device. In particular, the cigarette can include a tobacco medium accommodation portion and a humectant accommodation portion, and the aerosol-generating device can include a first heater for heating the tobacco medium accommodation portion and a second heater for heating the humectant accommodation portion.

[0009] The technical problems to be solved by the present embodiment are not limited to the technical problems described above, and other technical problems can be inferred from the following embodiments.

[0010] Means for Solving the Problems

[0011] An aerosol-generating system includes a cigarette including a tobacco medium accommodation portion and a humectant accommodation portion located at an upstream end or a downstream end of the tobacco medium accommodation portion.

However, the present application is not limited to the embodiments disclosed below, and can be implemented in various forms.

[0032] In the following embodiments, a singular expression includes a plural expression unless the context clearly indicates otherwise.

[0033] In the following embodiments, the term "comprising" or "having" means that a feature or constituent element described in the specification is present, and does not preclude the possibility of adding one or more other features or constituent elements.

[0034] In the following embodiments, the terms "upstream" and "downstream" are terms to indicate the relative positions of segments constituting a cigarette based on the direction in which a user inhales air using a cigarette. The cigarette includes a downstream end portion (i.e., a portion into which air enters) and an upstream end portion (i.e., a portion from which air is discharged) opposite thereto. When using a cigarette, a user bites the downstream end portion of the cigarette. The downstream end portion is located downstream of the upstream end portion, and the term "end portion" can also be written as "end" in one aspect.

[0035] In the drawings, the sizes of constituent elements can be exaggerated or reduced for convenience of explanation. For example, since the sizes and thicknesses of the structures shown in the drawings are arbitrarily shown for convenience of explanation, the present application is not limited to the sizes shown.

[0036] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the same. However, the present application is not limited only to the embodiments described herein, and can be implemented in various different ways.

[0037] Figures 1a-1b FIG. 1 is a diagram illustrating a segment constituting a cigarette according to an embodiment.

[0038] Referring to Figures 1a-1b , the cigarette 1a, 1b can include a humectant accommodation portion 10a, 10b, a tobacco medium accommodation portion 11a, 11b, and a filter portion 12a, 12b. In an aspect, although not shown in FIG. 1, the cigarette 1a, 1b can be wrapped by at least one of a wrapper.

[0039] The humectant accommodation portion 10a, 10b can contain a humectant. The humectant can include glycerin, propylene glycol (PG), and water. The humectant can further include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. In addition, the humectant accommodation portion 10a, 10b can further contain nicotine. However, the substances contained in the humectant accommodation portion 10a, 10b are not limited thereto.

[0040] The humectant accommodation portion 10a, 10b can include a wrapper for wrapping the humectant accommodation portion 10a, 10b. In addition, the humectant accommodation portion 10a, 10b can further include a material (e.g., an aluminum foil) having waterproof, water-repellent (oil-repellent), and heat-resistant characteristics for wrapping the humectant accommodation portion 10a, 10b. In this case, the aluminum foil can be located between the wrapper and the humectant accommodation portion 10a, 10b. Since the leakage of the humectant contained in the humectant accommodation portion 10a, 10b can contaminate the wrapper, in order to prevent this, the aluminum foil for wrapping the humectant accommodation portion 10a, 10b can be further included.

[0041] The humectant contained in the humectant accommodation portion 10a, 10b can maintain moisture in an aerosol generated when the heated cigarette 1a, 1b is heated at an appropriate level, thereby enabling the inherent taste of tobacco to be softened and the amount of atomization to be abundant.

[0042] The tobacco medium accommodation portion 11a, 11b can include a tobacco medium and a tobacco wrapper for wrapping the tobacco medium. The tobacco medium accommodation portion 11a, 11b can have a cylindrical shape, and generate smoke and / or an aerosol from the tobacco medium, which can be inhaled by a user through the filter portion 12a, 12b.

[0043] The tobacco medium accommodation portion 11a, 11b can include a solid material based on a tobacco raw material such as reconstituted leaf tobacco, tobacco leaf, reconstituted tobacco, or the like. In an embodiment, the tobacco medium accommodation portion 11a, 11b can be filled with a crimped reconstituted leaf sheet. The reconstituted leaf sheet can be formed to be crimped by being substantially curled, or folded, or compressed or contracted in a transverse direction with respect to a cylindrical axis. The porosity can be determined by adjusting the valley-to-valley distance between the crimped reconstituted leaf sheets, or the like.

[0044] In another embodiment, the tobacco medium containers 11a and 11b may be filled with tobacco leaves. Here, the tobacco leaves can be generated by finely slicing tobacco sheets (or pulp-reconstituted tobacco sheets). Alternatively, the tobacco medium containers 11a and 11b may be formed by stacking multiple tobacco shreds in the same direction (parallel) or randomly. Specifically, the tobacco medium containers 11a and 11b are formed by stacking multiple tobacco shreds, and multiple longitudinal channels through which aerosols can pass can be formed. In this case, depending on the size and arrangement of the tobacco shreds, the longitudinal channels may be uniform or non-uniform.

[0045] The tobacco medium in the tobacco medium containers 11a and 11b may include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Additionally, the tobacco medium may also include glycerol and propylene glycol.

[0046] In addition, the tobacco medium containers 11a and 11b may contain flavoring agents and / or other additives such as organic acids. For example, flavoring agents may include licorice, sucrose, fructose syrup, isosweet, cocoa powder, lavender, cinnamon, cardamom, celery, fenugreek, balsam bark, sandalwood, bergamot, geranium, honey extract, rose oil, vanilla, lemon oil, orange oil, peppermint oil, cinnamon, coriander, jasmine, chamomile, menthol, ylang-ylang, sage, spearmint, ginger, coriander, or coffee, etc. On the other hand, the tobacco medium containers 11a and 11b may include a portion of glycerol or propylene glycol.

[0047] The filter portions 12a and 12b may be composed of at least one segment and may include tobacco filter wrapping paper covering at least one segment. In one embodiment, the filter portions 12a and 12b may include at least one of a tubular filter, a cooling structure, and an embedded filter. The tubular filter is shaped to include an internal cavity. The tubular filter and the embedded filter may be made of a cellulose-based material (e.g., paper, acetate, etc.), and the cooling structure may be made of pure polylactic acid or by combining other biodegradable polymers with polylactic acid.

[0048] On the one hand, Figures 1a-1b The image shows filter portions 12a and 12b in contact with the upstream or downstream end portions of tobacco media containers 11a and 11b, and a portion of filter portions 12a and 12b may be located between humectant containers 10a and 10b and tobacco media containers 11a and 11b.

[0049] exist Figure 1a In the middle, the humectant container 10a is located at the upstream end of the tobacco medium container 11a, in Figure 1bIn the embodiment, the moisturizer accommodation portion 10b is located at the downstream end of the tobacco medium accommodation portion 11b. In an embodiment, a plurality of heaters can be used to heat the moisturizer accommodation portions 10a, 10b and the tobacco medium accommodation portions 11a, 11b, respectively, in which case the heating temperatures of the moisturizer accommodation portions 10a, 10b and the tobacco medium accommodation portions 11a, 11b can be different.

[0050] As Figure 1b shown, when the moisturizer accommodation portion 10b is located at the downstream end of the tobacco medium accommodation portion 11b, the heating temperature of the moisturizer accommodation portion 10b can be a prescribed temperature for aerosolizing glycerin. On the other hand, as Figure 1a shown, when the moisturizer accommodation portion 10a is located at the upstream end of the tobacco medium accommodation portion 11a, the high-temperature aerosol generated from the tobacco medium accommodation portion 11a passes through the moisturizer accommodation portion 10a, and thus the heating temperature of the moisturizer accommodation portion 10a can be lower than Figure 1b the prescribed temperature in

[0051] Figure 2 is a diagram for explaining an aerosol-generating system according to an embodiment.

[0052] Referring to Figure 2 , the aerosol-generating system can include an aerosol-generating device 210 and a cigarette 220. The cigarette 220 can include a moisturizer accommodation portion, a tobacco medium accommodation portion, and a filter portion. The cigarette 220 is the same as the cigarettes 1a, 1b explained in Figures 1a-1b , and thus a description thereof will be omitted.

[0053] The aerosol-generating device 210 can include a heater 212, a control portion 213, and a battery 214. In addition, the aerosol-generating device 210 can include an elongated cavity 211 for accommodating the cigarette 220.

[0054] Figure 2 The aerosol-generating device 210 shown in Figure 2 includes only components related to the present embodiment. Thus, it will be understood by those skilled in the art related to the present embodiment that the aerosol-generating device 210 can include other conventional components in addition to the components shown in

[0055] When the cigarette 220 is inserted into the aerosol-generating device 210, the aerosol-generating device 210 heats the heater 212. The temperature of the tobacco medium within the cigarette 220 rises by the heated heater 212, and thus an aerosol is generated from the tobacco medium. The generated aerosol is delivered to a user through the filter portion of the cigarette 220.

[0056] Battery 214 supplies power for the operation of aerosol generating apparatus 210. For example, battery 214 can supply power to heat heater 212 and to supply power required for the operation of control unit 213. In addition, battery 214 can supply power required for the operation of displays, sensors, motors, etc. installed in aerosol generating apparatus 210.

[0057] On the one hand, battery 214 can be a lithium iron phosphate (LiFePO4) or lithium-ion (Li-ion) battery, but is not limited to the examples mentioned above. For example, battery 214 can be a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, etc.

[0058] The heater 212 is heated by electricity supplied from the battery 214. When the cigarette 220 is inserted into the aerosol generating device 210, the heated heater 212 generates aerosol by raising the temperature of the tobacco medium inside the cigarette 220.

[0059] Reference Figure 2 The heater 212 can be an elongated structure inserted inside the cigarette 220. That is, when the cigarette 220 is inserted into the elongated cavity 211, the elongated heater 212 is located inside the cigarette 220. The heater 212 can be a blade type or a probe type combining cylinders and cones, and can be composed of multiple blades or multiple probes. On the one hand, the heater 212 may include a conductive track, in which case the conductive track can be disposed along the surface of the blade-type or probe-type substrate.

[0060] In another embodiment, the heater of the aerosol generating device 210 may be a cylindrical structure that partially surrounds the cigarette 220. The heater may be configured to heat the humectant reservoir and tobacco medium reservoir of the cigarette 220 by surrounding at least a portion of the cigarette 220. Additionally, the heater may be formed in a film shape having a resistive pattern capable of generating heat when electricity is applied externally. For example, the heater may include: a substrate made of a material such as polyimide; and conductive tracks disposed along the surface of the substrate. In yet another embodiment, the heater of the aerosol generating device 210 may be a single-sided structure near the upstream end portion of the cigarette 220.

[0061] On one hand, the aerosol generating device 210 can use multiple heaters to heat the humectant container and the tobacco medium container of the cigarette 220 respectively. That is, the aerosol generating device 210 may include a first heater for heating the tobacco medium container and a second heater for heating the humectant container, in which case the operating temperatures of the first heater and the second heater may be different.

[0062] Cigarette 220 includes a humectant container containing a humectant, thereby enabling the reduction or removal of the amount of humectant contained in the tobacco medium container. The humectant contains glycerin, etc. Due to the large molecular weight of glycerin, it is necessary to heat the humectant at a high temperature to aerosolize it. That is, when the tobacco medium container contains a humectant, it is necessary to heat the tobacco medium container at a high temperature to aerosolize the substances contained in the humectant. Conversely, by providing the humectant container as a separate section within cigarette 220, it is possible to reduce the amount of humectant contained in the tobacco medium container or remove it from the tobacco medium container. When reducing the amount of humectant contained in the tobacco medium container or removing the humectant, the tobacco medium container only needs to be heated within a temperature range sufficient to aerosolize nicotine.

[0063] In one embodiment, a first heater can heat the tobacco medium container at a first temperature range to aerosolize the nicotine contained therein. The first temperature range can be from 150°C to 200°C. Additionally, a second heater can heat the humectant container at a second temperature range higher than the first temperature range. The second temperature range is from 200°C to 300°C, preferably from 200°C to 250°C.

[0064] In one embodiment, the first heater may be a cylindrical structure, and the second heater may be a cylindrical structure, a planar structure, an elongated structure, or a combination thereof. (See also...) Figures 4a-4f The details will be explained.

[0065] The control unit 213 functions to control the overall operation of the aerosol generating device 210. The control unit 213 may include a processor. For example, the processor may be a microcontroller unit (MCU), but is not limited thereto.

[0066] The control unit 213 can be connected to multiple heaters to determine the temperature of each heater, and can determine whether to adjust the temperature of each heater based on the determined heater temperature. The control unit 213 can adjust the heater temperature, thereby adjusting the power supplied from the battery 214 to the multiple heaters. For example, the control unit 213 can adjust the magnitude or period of the pulse voltage supplied from the battery 214 to the heaters.

[0067] Figure 3 This is an exemplary cross-sectional view showing the structure of a humectant reservoir according to an embodiment.

[0068] Reference Figure 3In one embodiment, the humectant reservoir may be a porous matrix structure 30. The porous matrix structure 30 may be made of porous ceramic or cellulose acetate. In this case, the humectant may be impregnated in the humectant reservoir of the porous matrix structure 30.

[0069] In another embodiment, the humectant reservoir may be a tubular structure (or branch structure) 31. The tubular structure (or branch structure) 31 has an internal cavity, which may be the path through which the heater is inserted into the humectant reservoir. The humectant may be impregnated in the humectant reservoir of the tubular structure 31 or applied to the humectant reservoir of the branch structure 31.

[0070] In another embodiment, the humectant reservoir may be a cavity structure 32. The cavity structure 32, consisting only of the outer packaging paper, allows the humectant to be applied to the inside of the outer packaging paper.

[0071] In another embodiment, the humectant reservoir may be a honeycomb structure 33. When manufacturing the humectant reservoir, the honeycomb structure 33 can be formed through a squeezing, compression, and injection process. The empty spaces in the honeycomb structure 33 can serve as a path through which a heater is inserted into the humectant reservoir, acting as an airflow channel for air flowing in from the upstream end of the cigarette.

[0072] On one hand, the humectant container can be located at the upstream end or the downstream end of the tobacco medium container. When the humectant container is located at the upstream end of the tobacco medium container, it can be a porous matrix structure 30, a tubular structure (or branch structure) 31, a cavity structure 32, or a honeycomb structure 33. On the other hand, when the humectant container is located at the downstream end of the tobacco medium container, it can be a porous matrix structure 30, a tubular structure (or branch structure) 31, or a cavity structure 32.

[0073] The humectant can be contained in the humectant reservoir by being surrounded by a capsule or coated (or coated) with a film material. The capsule can be spherical or cylindrical in shape. The capsule film can be prepared from gums such as agar, pectin, sodium alginate, carrageenan, gelatin, or guar gum. Additionally, curing aids can be used as materials for forming the capsule film. Here, for example, calcium chloride can be used as a gelling aid. Furthermore, plasticizers can be used as materials for forming the capsule film. Here, glycerin and / or sorbitol can be used as plasticizers. Additionally, colorants can be used as materials for forming the film of capsule 324. The film material can be polylactic acid (PLA), but is not limited to this.

[0074] Figures 4a-4fThis is a diagram illustrating the structure and configuration of a plurality of heaters in one embodiment.

[0075] Reference Figure 4a The cigarette may include a tobacco medium container 410, a humectant container 420, and a filter portion 430. In one embodiment, the humectant container 420 may be located at the upstream end of the tobacco medium container 410.

[0076] although Figure 4a Not shown, the cigarette may be wrapped in at least one wrapping paper. Additionally, the humectant reservoir 420 may include a material (e.g., aluminum foil) having waterproof, hydrophobic (oil-repellent), and heat-resistant properties that wraps the humectant reservoir 420. In this case, the aluminum foil may be located between the wrapping paper and the humectant reservoir 420.

[0077] The tobacco medium container 410 may include tobacco leaves, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Additionally, the tobacco medium container 410 may contain flavoring agents and / or other additives such as organic acids.

[0078] The humectant container 420 may contain a humectant. The humectant may include glycerin, propylene glycol (PG), and water. Additionally, the humectant may include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

[0079] The filter portion 430 may be composed of at least one segment and may include tobacco filter wrapping paper covering at least one segment. The filter portion 430 may include, but is not limited to, at least one of a tubular filter, a cooling structure, and an embedded filter.

[0080] Because the glycerol contained in the humectant has a large molecular weight, it needs to be heated at a high temperature to aerosolize the glycerol. The cigarette includes a humectant container 420 containing the humectant, which allows for reducing the amount of humectant in the tobacco medium container 410 or removing the humectant from the tobacco medium container 410, thereby lowering the heating temperature of the tobacco medium container 410. On the other hand, the humectant contained in the humectant container 420 can maintain the moisture in the aerosol generated when the cigarette is heated at an appropriate level, thus making the inherent flavor of the tobacco milder and the atomization richer.

[0081] The aerosol generating apparatus can use a first heater 41a and a second heater 42a to heat the tobacco medium container 410 and the humectant container 420, respectively. By including the humectant container 420 in a separate section within the cigarette, the amount of humectant contained in the tobacco medium container 410 can be reduced or the humectant can be removed. The first heater 41a can heat the tobacco medium container 410 at a first temperature range to aerosolize the nicotine contained in the tobacco medium container 410. The first temperature range can be from 150°C to 200°C. Furthermore, the second heater 42a can heat the humectant container at a second temperature range higher than the first temperature range. The second temperature range is from 200°C to 300°C, preferably from 200°C to 250°C. However, the first and second temperature ranges are not limited to these.

[0082] like Figure 4a As shown, the first heater 41a and the second heater 42a can be cylindrical structures. The first heater 41a can heat the exterior of the tobacco medium container 410 by at least partially surrounding it, and the second heater 42a can heat the exterior of the humectant container 420 by at least partially surrounding it.

[0083] Since the humectant container 420 is located at the upstream end of the tobacco medium container 410, when a user inhales a cigarette, the air flowing in from the upstream end of the cigarette passes through the humectant container 420 and is heated by the second heater 42a, and the humectant (e.g., glycerin) is aerosolized. Additionally, the air passing through the humectant container 420 is heated by the first heater 41a as it passes through the tobacco medium container 410, and the tobacco medium (e.g., nicotine) is further aerosolized. At this time, since the air flowing into the tobacco medium container 410 is high-temperature air heated by the second heater 42a, the tobacco medium container 410 absorbs heat not only from the first heater 41a but also from the high-temperature air, thereby enabling aerosolization.

[0084] The following is omitted. Figure 4a Duplicate content.

[0085] like Figure 4bAs shown, the first heater 41a can be a cylindrical structure. The second heaters 42a and 42b can be cylindrical or planar structures. The first heater 41a can heat the exterior of the tobacco medium container 410 by at least partially surrounding it. The cylindrical second heater 42a can heat the exterior of the humectant container 420 by at least partially surrounding it, and the planar second heater 42b can heat the upstream end of the humectant container 420 by being located at the upstream end of the humectant container 420. On one hand, the planar second heater 42b is in contact with the upstream end of the humectant container 420, or it can be spaced a predetermined distance from the upstream end of the humectant container 420.

[0086] like Figure 4c As shown, the first heater 41a can be a cylindrical structure, and the second heater 42c can be an elongated structure. The first heater 41a can heat the exterior of the tobacco medium container 410 by at least partially surrounding it. The second heater 42c can heat the interior of the humectant container 420 by being inserted into it.

[0087] like Figure 4d As shown, the first heater 41a can be a cylindrical structure. The second heaters 42a and 42c can be cylindrical and elongated structures, respectively. The first heater 41a can heat the exterior of the tobacco medium container 410 by at least partially surrounding it. The cylindrical second heater 42a can heat the exterior of the humectant container 420 by at least partially surrounding it, and the elongated second heater 42c can heat the interior of the humectant container 420 by inserting into it.

[0088] like Figure 4e As shown, the first heater 41a can be a cylindrical structure. The second heaters 42b and 42c can be planar or elongated structures. The first heater 41a can heat the exterior of the tobacco medium container 410 by at least partially surrounding it. The planar second heater 42b heats the upstream end of the humectant container 420 by being located at the upstream end of the humectant container 420, while the elongated second heater 42c heats the interior of the humectant container 420 by being inserted into its interior. On one hand, the planar second heater 42b is in contact with the upstream end of the humectant container 420, or it can be spaced apart from the upstream end. On the other hand, the planar second heater 42b can be combined with the elongated second heater 42c.
