Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aerosol generating, in particular to an aerosol generating article. BACKGROUND

[0002] Compared with traditional combustible aerosol generating articles (hereinafter referred to as traditional aerosol generating articles), the current heat-not-burn aerosol generating articles (hereinafter referred to as HNB aerosol generating articles) have a lower heating temperature, which may have a problem of insufficient smoke amount, so a certain amount of smoke generating agent is usually added to the substrate to ensure that there is enough aerosol amount and aroma amount during smoking to meet the visual, olfactory, and psychological needs of consumers. The smoke generating agent is generally glycerol (glycerin), and glycerol belongs to a hydrophilic substance, so the water absorption performance of the substrate to which glycerol is applied is greatly improved.

[0003] Research has confirmed that the HNB substrate to which a large amount of glycerol is applied has an equilibrium moisture content of about 15% under normal room temperature and humidity conditions. In this case, after the cigarette case storing the HNB aerosol generating article is opened and exposed, the moisture content of the substrate in the HNB aerosol generating article will continuously change until it reaches about the equilibrium moisture content. That is, after being opened and placed in a room at normal temperature for a period of time, the HNB aerosol generating article will have a substrate "water absorption" and "humidity return" phenomenon, thereby deviating from its optimal smoking state.

[0004] Therefore, how to prevent the substrate in the HNB aerosol generating article from absorbing water and returning humidity has become one of the key problems in the design and production of HNB aerosol generating articles. SUMMARY

[0005] The technical problem to be solved by the utility model is to provide an improved aerosol generating article.

[0006] The technical scheme adopted by the utility model to solve the technical problem is that an aerosol generating article is constructed, which comprises a substrate section in a columnar shape; the substrate section comprises a substrate body, a wrapping layer, and a water barrier layer; the wrapping layer is arranged on the outer periphery of the substrate body; and the water barrier layer is arranged on the outer surface of the wrapping layer and is configured to decompose when reaching a set temperature.

[0007] In some embodiments, the water barrier layer covers the entire outer surface of the wrapping layer.

[0008] In some embodiments, the water barrier layer covers at least one end of the substrate body.

[0009] In some embodiments, the water barrier layer comprises a water barrier film that can be thermally decomposed.

[0010] And / or, the set temperature is greater than or equal to 200 DEG C.

[0011] In some embodiments, the thickness of the waterproof layer is 20μm-250μm.

[0012] In some embodiments, the waterproof layer is formed on the outer surface of the wrapping layer by a thermoplastic sealing process.

[0013] In some embodiments, the substrate segment is further comprising a hollow, through-end cooling section disposed at one end.

[0014] In some embodiments, a filter section is further included, the filter section being disposed at one end of the cooling section away from the matrix section.

[0015] In some embodiments, an outer casing structure is also included, which covers the periphery of the matrix segment, the cooling segment, and the filter segment.

[0016] In some embodiments, a plug section is further included, the plug section being disposed at one end of the matrix section.

[0017] The aerosol generating product of this utility model has the following beneficial effects: By setting a water-proof layer on the outer surface of the coating layer that encapsulates the matrix body, and the water-proof layer is configured to decompose when a set temperature is reached, the aerosol generating product can be prevented from absorbing water and becoming damp without affecting the generation of aerosols. This ensures the amount of aerosol mist and the taste of the aerosol generated by the aerosol generating product, and enhances the consumer experience. Attached Figure Description

[0020] Figure 2 yes Figure 1 The diagram shows a partial structural cross-sectional view of the aerosol-generated product. Detailed Implementation

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by terms such as "inner," "outer," etc., are based on the directions or positional relationships shown in the accompanying drawings, and are constructed and operated in a specific orientation. They are only for the convenience of describing this technical solution and do not indicate that the device or element referred to must have a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0022] It should also be noted that, unless otherwise explicitly specified and limited, terms such as “connection,” “fixed,” and “set up” should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. When a component is referred to as being “on” or “below” another component, that component can be located “directly” or “indirectly” on the other component, or there may be one or more intermediary components.

[0023] Figure 1 Some preferred embodiments of the aerosol generating article of this utility model are shown. The aerosol generating article is cylindrical in shape and can be detachably assembled onto an aerosol generating device. It generates aerosol through heating without combustion for users to inhale. This aerosol generating article has the advantages of low manufacturing cost, easy storage, high aerosol volume and aroma output, and a good consumer experience.

[0024] like Figure 1 and Figure 2 As shown, in some embodiments, the aerosol-generating article may include a matrix segment 10. The matrix segment 10 may be generally columnar; specifically, in some embodiments, the matrix segment 10 may be cylindrical. The matrix segment 10 can generate aerosols under heating conditions.

[0025] In some embodiments, the matrix segment 10 may include a matrix body 11, a wrapping layer 12, and a water-resistant layer 13. The wrapping layer 12 is disposed on the outer periphery of the matrix body 11, forming a columnar structure. The water-resistant layer 13 is disposed on the outer surface 121 of the wrapping layer 12. It is configured to decompose upon reaching a set temperature, thereby blocking the matrix body 11 from external air, preventing the matrix body 11 from absorbing moisture from the air, preventing the matrix body 11 from absorbing water and becoming damp, and by decomposing upon reaching the set temperature, it does not affect the heating of the matrix body 11 and the generation of aerosols, ensuring normal suction for the consumer.

[0026] In some embodiments, the matrix body 11 can be a solid material in the form of strips, flakes, granules or integral molding made from the leaves and / or stems of plants (e.g. tobacco), and aroma components can be further added to the solid material.

[0027] In some embodiments, the wrapping layer 12 can be cigarette paper, which can wrap the matrix body 11 to keep the matrix body 11 in shape and prevent the matrix body 11 from disintegrating before and after heating. The wrapping layer 12 is disposed on the outer periphery of the matrix body 11, that is, the wrapping layer 12 wraps the circumferential surface of the matrix body 11, while the two ends of the matrix body 11 can be exposed to facilitate aerosol flow.

[0028] In some embodiments, the waterproof layer 13 may cover the entire outer surface 121 of the wrapping layer 12. In some embodiments, the waterproof layer 13 may cover at least one end of the matrix body 11, that is, to cover the exposed part of the matrix body 11, thereby blocking the matrix body 11 and the outside air in all directions. In normal use, the storage box for storing aerosol-generated products usually needs to be sealed with cellophane and wrapped with aluminum foil inside. After opening, the cellophane is damaged and the aluminum foil cannot be completely sealed, which will cause the internal tobacco material to continuously absorb moisture from the outside air until the equilibrium moisture content is reached. That is, the aerosol-generated product will gradually and slowly absorb water and become damp. If consumers tear off the aluminum foil at the end after opening the box for convenience, this will cause the aerosol-generating product to become damp more quickly. This application addresses this by covering the entire outer surface 121 of the wrapping layer 12 with the waterproof layer 13. This ensures that even when the aerosol-generating product storage box is open, the matrix body 11 in the aerosol-generating product does not easily come into contact with moisture in the air and absorb it. Furthermore, there is no need to reduce the glycerin ratio to alleviate the water absorption characteristics of the matrix body 11, thus preserving the taste and aerosol volume of the aerosol. Of course, it is understandable that in some other embodiments, the waterproof layer 13 may only cover the outer surface of the wrapping layer 12.

[0029] In some embodiments, the waterproof layer 13 may include a thermally decomposable waterproof membrane made of a non-toxic, hydrophobic (or non-hydrophilic) material that is easily decomposed and volatilized upon heating, and whose decomposition products are also non-toxic. Specifically, the material of the waterproof membrane may be at least one of polylactic acid (PLA), polyhydroxyalkanoate (PHA), polycarbonate, polycaprolactone, and polyhydroxybutyrate (PHB). In some embodiments, the set temperature for the thermal decomposition of the waterproof layer 13 may be greater than or equal to 200°C, and more preferably, the set temperature may be 200°C to 250°C. That is, when the entire matrix segment 10 is heated to 200°C, the waterproof layer 13 can rapidly decompose / vaporize under this temperature condition, and the decomposition products are also non-toxic and harmless.

[0030] In some embodiments, the waterproof layer 13 can be formed on the outer surface 121 of the wrapping layer 12 after the wrapping layer 12 is molded around the matrix body 11, through a thermoplastic sealing process. Of course, in other embodiments, other processes that can form the waterproof layer 13 on the outer surface 121 of the wrapping layer 12 can also be used. By first using the wrapping layer 12 to wrap the matrix body 11 to form a columnar structure and then forming the waterproof layer 13 on the outer surface 121 of the wrapping layer 12, the difficulty of forming the waterproof layer 13 can be reduced, because the waterproof layer 13 usually lacks strength and hardness and is difficult to directly wrap around the matrix body 11.

[0031] In some embodiments, the thickness of the waterproof layer 13 can be 20μm-250μm. Using this thickness range can meet both the packaging strength requirements and the thermal decomposition rate requirements. That is, it can both ensure its molding and facilitate its thermal decomposition, thus shortening the thermal decomposition time.

[0032] In some embodiments, the aerosol-generating article further includes a cooling section 20. The cooling section 20 is disposed at one end of the matrix section 10. The cooling section 20 is coaxially arranged with the matrix section 10 and is hollow with both ends open to form a channel for aerosol flow within it. In some embodiments, the cooling section 20 may be a corrugated tube or a paper tube structure. The cooling section 20 may be generally cylindrical, and its outer diameter may be comparable to the outer diameter of the matrix section 10, thereby making the outer wall surface of the formed aerosol-generating article smooth and aesthetically pleasing.

[0033] In some embodiments, the aerosol generating article further includes a filter tip section 30. The filter tip section 30 is disposed at the end of the cooling section 20 away from the matrix section 10 and is coaxially arranged with the cooling section 20, for user inhalation, and can filter aerosols. In some embodiments, the filter tip section 30 may be cylindrical, specifically, it may be cylindrical, and its outer diameter may be comparable to the outer diameter of the cooling section 20. In some embodiments, the filter tip section 30 may be made of fibrous materials such as cellulose acetate or filter cotton.

[0034] In some embodiments, the aerosol generating article further includes a plug section 40 disposed at the end of the matrix section 10 away from the cooling section 20. The plug section 40 is coaxially arranged with the matrix section 10 and serves to prevent the assembled matrix section 10 from detaching. The outer diameter of the plug section 40 is approximately the same as the outer diameter of the matrix section 10, thereby ensuring a smooth and aesthetically pleasing outer wall surface of the assembled aerosol generating article. In other embodiments, the plug section 40 may be omitted.

[0035] In some embodiments, the aerosol-generating article further includes an outer packaging structure 50, which may cover the outer periphery of the plug section 40, the matrix section 10, the cooling section 20, and the filter section 30. The outer packaging structure 50 may be a paper material, such as molded paper. In some embodiments, the inner wall surface of the outer packaging structure 50 may be bonded and fixed to the outer wall surface of the plug section 40, the matrix section 10, the cooling section 20, and the filter section 30.

[0036] In some embodiments, the outer packaging structure 50 may include a first outer packaging layer 51 and a second outer packaging layer 52; the first outer packaging layer 51 covers the outer periphery of the plug section 40, the matrix section 10, and the cooling section 20, and is tightly fitted to the outer sidewalls of the plug section 40, the matrix section 10, and the cooling section 20, and the first outer packaging layer 51 may be a forming paper; the second outer packaging layer 52 covers the outer periphery of the filter section 30 and extends toward the first outer packaging layer 51 to partially cover the first outer packaging layer 51, and the second outer packaging layer 52 may be tipping paper (also known as tipping paper). In some embodiments, the first outer packaging layer 51 and the second outer packaging layer 52 may be an integral structure, and in some embodiments, the second outer packaging layer 52 may be omitted. In other embodiments, the aerosol generating article is limited to including only the segments listed above, and may also include other functional segments.

It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
