[Technical Field]

[0001] [Cross-Citation of Related Applications] The present invention is based on and claims priority from a Chinese patent application having application number 202320264965.6 and filing date February 20, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to the technical field of smoke-producing products, and in particular to aerosol-generating products and aerosol-generating product units. [Background technology]

[0003] In the related art, the aerosol-generating matrix of a capsule-shaped aerosol-generating product is usually in the form of a thread, powder, particle, liquid, etc., and therefore, these aerosol-generating products generally require a separate packaging material such as wrapping paper or a packaging case to encase the aerosol-generating matrix so as to prevent the aerosol-generating matrix from loosening.

[0004] However, when packaging materials such as wrapping paper and packaging cases are heated together with the aerosol-generating matrix in the aerosol-generating device, they tend to produce unpleasant odors, which affect the texture of the food. Summary of the Invention

[0005] In view of the above, it is desirable that embodiments of the present invention provide an aerosol-generating product and an aerosol-generating product unit that can improve the user's usage experience.

[0006] To achieve the above object, one embodiment of the present invention provides an aerosol-generating product comprising at least an aerosol-generating matrix of unitary construction having a first air passage, at least a portion of which is exposed.

[0007] In one embodiment, the exposed portion of the aerosol-forming matrix remains exposed at all times.

[0008] In one embodiment, the aerosol-forming product comprises a removable wrapper, and after removal of the wrapper, at least a portion of the aerosol-forming matrix is ​​exposed.

[0009] In one embodiment, the aerosol-generating product comprises a filter provided at one end of the aerosol-generating matrix along a first direction.

[0010] In one embodiment, the aerosol-generating matrix comprises a connecting segment located at one end of the heating segment along a first direction, and a heating segment, the connecting segment protruding into the interior of the filter, and the heating segment being exposed at least during the use phase of the aerosol-generating product.

[0011] In one embodiment, the filter comprises a functional segment including a filtering segment for filtering at least aerosols, and an outer coating layer covering the outer periphery of the functional segment and the connecting segment.

[0012] In one embodiment, the functional segment further comprises a temperature reducing segment located between the filtration segment and the aerosol-generating matrix.

[0013] In one embodiment, the functional segment is spaced apart from the connecting segment, and the side wall of the outer coating layer has a second air passage located in a space between the functional segment and the connecting segment and penetrating the side wall of the outer coating layer.

[0014] In one embodiment, the entire aerosol-forming matrix is ​​in exposed form.

[0015] In one embodiment, the aerosol-generating matrix has a mounting location.

[0016] In one embodiment, the mounting positioning portion is a mounting positioning hole that penetrates at least one end of the aerosol-generating matrix along the first direction.

[0017] In one embodiment, the first air passage penetrates at least one end of the aerosol-generating matrix along a first direction.

[0018] In one embodiment, the first air passage is provided in at least one of the interior of the aerosol-generating matrix and the outer wall of the aerosol-generating matrix.

[0019] In one embodiment, the first airway is a straight airway.

[0020] In one embodiment, the first air passage is a spiral air passage, and the spiral air passage has a curved shape with a non-zero curvature in at least a partial region along the extension direction.

[0021] In one embodiment, the aerosol-forming matrix is ​​cylindrical.

[0022] Another embodiment of the present invention comprises: an aerosol-generating product as described above; and a blister-covered packaging container in which the aerosol-generating product is enclosed.

[0023] An embodiment of the present invention provides an aerosol-generating product and an aerosol-generating product unit in which the aerosol-generating matrix of the aerosol-generating product has an integral structure with a first air passage, and at least a portion of the aerosol-generating matrix is ​​exposed. Because the aerosol-generating matrix has an integral structure that is not easily loosened, at least a portion of the aerosol-generating matrix can be directly exposed to the outside. During use of the aerosol-generating product, the exposed portion of the aerosol-generating matrix is ​​not covered by other packaging materials such as wrapping paper or a packaging case. This prevents the aerosol-generating product from generating unpleasant odors due to heating of the packaging materials such as wrapping paper or a packaging case. This improves the user experience.

[0025] In the description of the embodiments of the present invention, the orientation or positional relationship indicated by terms such as "first direction" is based on the orientation or positional relationship shown in Figure 1, and these orientation terms are used only to facilitate and simplify the description of the present application, and do not indicate or suggest that a specified device or component necessarily has a specific orientation or must be configured or operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0026] One embodiment of the present invention provides an aerosol-generating product 10, which, as shown in Figures 1, 2 and 10, comprises at least an aerosol-generating matrix 11, which is a structure having a first air passage 11a, at least a portion of which is exposed. The aerosol-generating product 10 is intended to be used by fitting it to an aerosol-generating device having a heating unit, which heats and atomizes the aerosol-generating matrix 11 to generate an aerosol that can be inhaled by a user or used for medicinal or cosmetic purposes.

[0027] The aerosol-generating product 10 may have only the aerosol-generating matrix 11 shown in Figure 10 without any other components, or may have both the aerosol-generating matrix 11 and other components. For example, as shown in Figure 1, the aerosol-generating product 10 is provided with a filter 12, which is provided at one end of the aerosol-generating matrix 11 along the first direction, allowing the user to inhale the aerosol filtered through the filter 12.

[0028] The heating unit may be used in a variety of ways, including central heating and peripheral heating. The central heating method refers to inserting a heating unit into the aerosol-generating matrix 11 to heat and bake the aerosol-generating matrix 11 from the inside to the outside. The peripheral heating method refers to providing a heating unit on the periphery of the aerosol-generating matrix 11 to heat and bake the aerosol-generating matrix 11 from the outside to the inside. Specific examples of these heating methods include, but are not limited to, resistance heating, electromagnetic heating, infrared heating, microwave heating, and laser heating.

[0029] The aerosol-generating product 10 according to the embodiment of the present invention may be applied to suction by heating and combustion, or by heating but not combustion. In the embodiment of the present invention, the aerosol-generating product 10 is described as being applied to suction by heating but not combustion.

[0030] The aerosol-generating matrix 11 is a structure, and by structure, we mean that the aerosol-generating matrix 11 has a certain strength and a specific shape due to processing, and is structured to be resistant to loosening, i.e., the aerosol-generating matrix 11 is not in a form that is prone to loosening, such as thread, powder, particles, or liquid. In this embodiment, structure means a one-piece structure.

[0031] The specific configuration of the aerosol-generating matrix 11 is not limited herein. For example, in one embodiment, the aerosol-generating matrix 11 may be composed of an atomizing medium itself, such as a smoke-producing flavoring medium. In other embodiments, the aerosol-generating matrix 11 may include a substrate and the atomizing medium provided on the substrate. The substrate may be, for example, carbon fiber that can withstand high temperatures. In this way, providing a substrate not only increases the strength of the aerosol-generating matrix 11, but also allows it to withstand relatively high temperatures without generating unpleasant odors.

[0032] The specific components of the aerosol-generating matrix 11 are not limited herein, but by way of example, in one embodiment the aerosol-generating matrix 11 may include a botanical component, an auxiliary component, a smoke generating component, a binder component, etc.

[0033] In one embodiment, the plant ingredients are one or a combination of powders obtained by crushing raw tobacco leaves, tobacco leaf fragments, tobacco stems, tobacco powder, aromatic plants, etc. The plant ingredients are the main source of the product's aroma, and endogenous substances in the plant ingredients, such as nicotine, enter the human bloodstream when atomized, promoting the production of dopamine in the pituitary gland and providing physiological satisfaction.

[0034] In one embodiment, the auxiliary component may be one or a combination of inorganic fillers, lubricants, and emulsifiers. Examples of inorganic fillers include ground calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic fillers can provide skeletal support for the plant components. At the same time, the inorganic fillers have micropores, which can improve the porosity of the wall material after the plant components are molded, thereby improving the aerosol release rate.

[0035] Lubricants include one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can improve particle fluidity, reduce friction between particles, homogenize the density of the entire particle distribution, reduce the pressure required for molding using a mold, and reduce mold wear.

[0036] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Twain-80, and polyvinyl alcohol. Emulsifiers can mitigate flavor loss during storage to a certain extent, enhance flavor stability, and improve the sensory quality of products. Emulsifiers (also known as surfactants) reduce the interfacial tension between water-soluble and water-insoluble components in a mixed system, forming a relatively firm layer on the surface of the droplets, or an electric double layer formed on the surface of the droplets due to the charge of the emulsifier, preventing the droplets from coagulating and maintaining a uniform emulsion. Homogenizing the emulsion of two immiscible components can improve the consistency of product quality.

[0037] The smoke generating agent component generates a large amount of vapor upon heating, thereby enhancing the amount of vapor produced by the smoke generating product. In one embodiment, the smoke generating agent can be one or more of the following: monohydric alcohols (e.g., menthol), polyols (e.g., propylene glycol, triethylene glycol, 1,3-butanediol and glycerin), esters of polyols (e.g., glycerol monoacetate, glycerol diacetate, or glycerol triacetate), monocarboxylic acids, polycarboxylic acids (e.g., lauric acid, myristic acid), or aliphatic esters of polycarboxylic acids (e.g., dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, triactin, mesoerythritol, glycerol diacetate, triethyl citrate, phenylmethyl phenyl benzoate, ethyl vanilla, glycerol tributyrate, and lauryl acetate).

[0038] In one embodiment, the adhesive component is a natural plant extract and a non-ionized modified viscous polysaccharide, such as one or a combination of tamarind polysaccharide, proline polysaccharide, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive adheres to the product's component materials by wetting the interface and generates intermolecular attraction, thereby bonding the component materials, such as powders and liquids. The simultaneous selection of a natural plant extract and a non-ionized modified adhesive can prevent the release of harmful substances such as methanol, formaldehyde, and acrolein due to colloidal modification, thereby improving product safety.

[0039] For example, the aerosol-generating matrix 11 may be a particle conjugate, such as a recombinant tobacco vehicle containing components such as a smoke-generating agent and tobacco. The aerosol-generating matrix 11 may be a one-piece structure formed by injection, compression, or extrusion. Extrusion is a processing method in which a raw material mixture is fed into an extruder, and the material is forced forward by the screw through the action between the barrel and screw of the extruder, and the material passes continuously through a die to produce various cross-sectional products or semi-finished products. The aerosol matrix formed by extrusion has a striped shape.

[0040] Because the aerosol-generating matrix 11 is a particle-bound body, it becomes an integrated medium after being sucked in by heat or after heating is stopped, and is less likely to separate and fall. This solves the problems that arise with prior art aerosol-generating matrices 11 that are in the form of sheets, threads, or scattered particles, such as sheets coming off, thread-like or particle components falling off, and difficulty in cleaning.

[0041] The shape of the aerosol-generating matrix 11 is not limited as long as it can provide the first air passages 11a. For example, the aerosol-generating matrix 11 may be cylindrical, as shown in Figure 2. The cross-sectional shape of the cylindrical aerosol-generating matrix 11 may be circular as shown in Figure 2, or may be other shapes such as polygonal or elliptical.

[0042] The first air passage 11a is used to increase the surface area of ​​the aerosol-generating matrix 11 (the side wall of the first air passage 11a corresponds to part of the surface of the aerosol-generating matrix 11), allowing the heat acting on the aerosol-generating matrix 11 to enter the interior of the aerosol-generating matrix 11 from the surface of the aerosol-generating matrix 11, thereby improving heating efficiency.

[0043] In the related art, some aerosol-generating matrices have naturally formed micropores within them. For example, in an aerosol-generating matrix that is a particle aggregate, the gaps between particles constitute the micropores. However, the first air passages 11a described in the present invention are different from micropores. The first air passages 11a described in the present invention are macropores, while micropores are micropores, and the dimensions of the first air passages 11a, such as their cross-sectional area and length, are much larger than those of micropores. Since the first air passages 11a are mainly formed by processing, the dimensions of the first air passages 11a, such as their cross-sectional area and length, can be changed according to design requirements, while the dimensions of the micropores are determined by the gaps between particles, and the dimensions of the micropores, such as their cross-sectional area and length, are difficult to change significantly through processing.

[0044] The number of first air passages 11a may be one or more.

[0045] The first air passages 11a may be provided inside the aerosol-generating matrix 11 as shown in Fig. 2, or may be provided on the outer wall of the aerosol-generating matrix 11 as shown in Fig. 4. When there are multiple first air passages 11a, some of the first air passages 11a shown in Fig. 5 are provided inside the aerosol-generating matrix 11, and other parts of the first air passages 11a are provided on the outer wall of the aerosol-generating matrix 11.

[0046] The first air passage 11a can extend along a first direction of the aerosol-generating matrix 11, for example, the first air passage 11a may penetrate at least one end of the aerosol-generating matrix 11 along the first direction, or may not penetrate either end of the aerosol-generating matrix 11 along the first direction.

[0047] The first direction is the arrangement direction of the functional segment 121 and the aerosol generating matrix 11, the aerosol generating product 10 is inserted into the aerosol generating device along the first direction, the aerosol generating product 10 is removed from the aerosol generating device along the first direction, and the length of the aerosol generating matrix 11 in the first direction may be longer, shorter, or the same as the length in other directions.

[0048] For example, if the aerosol-generating matrix 11 has a cylindrical outer contour, the first direction is the axial direction of the aerosol-generating matrix 11, and the length of the aerosol-generating matrix 11 in the axial direction may be smaller than the diameter.

[0049] Also, for example, if the external contour of the aerosol-generating matrix 11 is a rectangular prism, the first direction is still the direction defined above, i.e., the direction in which the functional segments 121 and the aerosol-generating matrix 11 are arranged, or the direction in which the aerosol-generating product 10 is inserted and removed from the aerosol-generating device, and the first direction of the aerosol-generating matrix 11 may be any of the length, width, or height directions of the rectangular prism.

[0050] When the aerosol-generating matrix 11 is used alone, i.e., not combined with the functional segment 121, the first direction is the perpendicular direction of the distance between both ends of the aerosol-generating matrix 11; for example, if the aerosol-generating matrix 11 is cylindrical, the first direction is the perpendicular direction of the distance between both end faces; for example, if the aerosol-generating matrix 11 is cylindrical with a cross section having a triangular, polygonal, oval, elliptical or other shape, the first direction is the axial direction; and if the aerosol-generating matrix 11 is rectangular, the first direction of the aerosol-generating matrix 11 may be any one of the length, width or height directions of the rectangular.

[0051] The form in which the first air passage 11a penetrates at least one end of the aerosol-generating matrix 11 along the first direction can vary; for example, in some embodiments, the first air passage 11a may penetrate one end of the aerosol-generating matrix 11 along the first direction, while the other end may be a closed end.

[0052] In some other embodiments, the first air passages 11a may penetrate opposite ends of the aerosol-generating matrix 11 in the first direction, i.e., the airflow can flow from one end of the aerosol-generating matrix 11 in the first direction to the other end of the aerosol-generating matrix 11 in the first direction via the first air passages 11a.

[0053] In some embodiments, when multiple first air passages 11a are provided, some of the first air passages 11a may penetrate one end of the aerosol-generating matrix 11 along the first direction, while other of the first air passages 11a may penetrate the other end of the aerosol-generating matrix 11 along the first direction. All of the first air passages 11a may penetrate the same end of the aerosol-generating matrix 11 along the first direction, while the other ends may all be closed ends. Each of the first air passages 11a may penetrate both ends of the aerosol-generating matrix 11 that are opposite to each other along the first direction.

[0054] When the aerosol suction volume is constant, the first air passage 11a extending along the first direction of the aerosol-generating matrix 11 may extend the airflow path, thereby increasing the speed at which the airflow flows through the aerosol-generating matrix 11 and increasing the impact force of the airflow, thereby mixing the aerosol uniformly, and further improving the extraction efficiency and uniformity of the aerosol in the aerosol-generating matrix 11, thereby improving the user's inhalation experience.

[0055] Furthermore, it is more advantageous to have the first air passage 11a penetrate both ends of the aerosol-generating matrix 11 along the first direction than to have the first air passage 11a penetrate one end of the aerosol-generating matrix 11 along the first direction in order to reduce the inhalation resistance of the user.

[0056] In some other embodiments, the first air passages 11 a may extend in other directions in the aerosol-generating matrix 11. For example, the first air passages 11 a may extend along the radial or circumferential direction of the aerosol-generating matrix 11.

[0057] The first air passage 11a may be a straight air passage as shown in Figures 3 to 6, or may be a spiral air passage as shown in Figures 6 to 8. When there are a plurality of first air passages 11a, some of the first air passages 11a may be straight air passages, while other parts of the first air passages 11a may be spiral air passages.

[0058] A straight air passage is an air passage that extends along a straight line, in other words, the extension direction of a straight air passage is a straight line.

[0059] A helical airway is an airway in which at least a portion of the area along its extension direction (for example, along the extension direction of the helical airway) exhibits a curved shape with a non-zero curvature, and the helical airway may be configured to consist of curved portions with a non-zero curvature and straight portions with a curvature of 0, or may be configured to have no straight portions with a curvature of 0 and to consist only of curved portions with a curvature of 0. In other words, the helical airway does not have to extend along a straight line from the start point to the end point in its extension direction.

[0060] The shape of the cross section perpendicular to the first direction of the aerosol generating matrix 11 in the first airway 11a is not limited, but for example, the cross section may be circular, polygonal (including but not limited to triangular, rectangular, rectangular, etc.), elliptical, track-shaped, irregular, etc.

[0061] The exposure of at least a portion of the aerosol-generating matrix 11 means that during heating, at least one segment of the aerosol-generating matrix 11 along the first direction (i.e., the exposed portion 11b shown in Figure 1) is directly exposed to the outside without being wrapped in any packaging material such as wrapping paper, a packaging case, a packaging film, etc. For example, the outer surface of part of the side wall of the aerosol-generating matrix 11 may be exposed, or at least one end surface of the aerosol-generating matrix 11 and the outer surface of part of the side wall may be exposed.

[0062] 1, the exposed region 11b is the main region that is heated by the heating unit, and includes the region of the aerosol-generating matrix 11 that is directly heated by the heating unit and regions along the radial direction of the aerosol-generating matrix 11 that are indirectly heated by heat conduction from the region that is directly heated by the heating unit. For example, when a central heating system is used, the exposed region 11b includes the inner surface of the aerosol-generating matrix 11 that is directly heated by the heating unit and all regions extending along the radial direction to the outer surface of the side wall of the aerosol-generating matrix 11. When a peripheral heating system is used, the exposed region 11b includes the outer surface of the side wall of the aerosol-generating matrix 11 that is directly heated by the heating unit and all regions extending along the radial direction to the center of the aerosol-generating matrix 11.

[0063] The exposed portion 11b of the aerosol-generating matrix 11 may or may not be exposed before and after use of the aerosol-generating product 10. For example, in some embodiments, as shown in Figure 1, the exposed portion of the aerosol-generating matrix 11 (i.e., the exposed portion 11b) may always remain exposed. That is, regardless of the use of the aerosol-generating product 10, the exposed portion 11b is always directly exposed to the outside without being wrapped by any packaging material such as a wrapping paper, a packaging case, or a packaging film.

[0064] For an aerosol-generating matrix 11 in which the exposed portion of the aerosol-generating matrix 11 is always kept exposed, it is possible to save costs for packaging materials such as wrapping paper, packaging cases, and packaging films, and to reduce pressure on environmental protection.

[0065] In some other embodiments, the aerosol-generating product 10 is provided with a removable wrapping material, and after the wrapping material is removed, at least a portion of the aerosol-generating matrix 11 is exposed. That is, before using the aerosol-generating product 10, the wrapping material is wrapped around at least the exposed portion 11b of the aerosol-generating matrix 11. That is, the wrapping material is wrapped around at least the exposed portion 11b of the aerosol-generating matrix 11. If the exposed portion 11b has an end surface that is exposed, the end surface may or may not be wrapped. Alternatively, if the aerosol-generating matrix 11 further has an unexposed portion, or if the aerosol-generating product 10 further has other components other than the aerosol-generating matrix 11, the unexposed portion or component may or may not be wrapped.

[0066] The packaging material is any of a configuration used for packing, such as wrapping paper, a packaging case, and a packaging film.

[0067] The material of the packaging material is not limited, but may include, for example, one or a combination of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE (polyethylene), PBAT (butylene adipate-co-terephthalate), silicone rubber, etc., but is not limited to these.

[0068] When the aerosol-generating product 10 needs to be used, the user removes the packaging material to expose the exposed portion 11b of the aerosol-generating matrix 11 to the outside, and then incorporates the aerosol-generating product 10 into an aerosol-generating device for use.

[0069] Furthermore, for an aerosol-generating product 10 provided with removable packaging, the packaging may be provided in a reusable configuration, and after using the aerosol-generating product 10, the user can remove the aerosol-generating product 10 from the aerosol-generating device and wrap the packaging around at least the exposed portion 11b of the aerosol-generating matrix 11.

[0070] In addition, exposure as used in the present invention means that the corresponding portion of the aerosol-generating matrix 11 itself is exposed to the outside, i.e., the aerosol-generating product 10 does not have any other structure that shields, packs or covers that portion of the aerosol-generating matrix 11, but does not include the aerosol-generating device shielding, packing or covering that portion of the aerosol-generating matrix 11 during use.

[0071] For example, as shown in Figure 10, the aerosol-generating matrix 11 may be entirely exposed. That is, the entire aerosol-generating matrix 11 may be exposed to the outside. In one example, the aerosol-generating matrix 11 is entirely exposed when the aerosol-generating product 10 is in use. In another example, the aerosol-generating matrix 11 is entirely exposed whether the aerosol-generating product 10 is in use or not. Such an aerosol-generating matrix 11 is particularly suitable for aerosol-generating products 10 that do not have any other components other than the aerosol-generating matrix 11. Of course, aerosol-generating products 10 that simultaneously have the aerosol-generating matrix 11 and other components can also be designed to have the entirely exposed aerosol-generating matrix 11, depending on the needs.

[0072] The aerosol-generating matrix 11 of the aerosol-generating product 10 according to an embodiment of the present invention is of one piece, and at least a portion of the aerosol-generating matrix 11 is exposed. Therefore, during use of the aerosol-generating product 10, the exposed portion of the aerosol-generating matrix 11 is not covered by other packaging materials such as wrapping paper or a packaging case. Therefore, the aerosol-generating product 10 does not generate unpleasant odors when the packaging materials such as wrapping paper or a packaging case are heated, thereby improving the user's usage experience.

[0073] In one embodiment, as shown in Figures 1 and 3, for an aerosol-generating product 10 provided with a filter 12, the aerosol-generating matrix 11 comprises a connecting segment 11c located at one end of the heating segment 11d along the first direction, and a heating segment 11d, wherein the connecting segment 11c protrudes into the interior of the filter 12 and the heating segment 11d is exposed at least during the use phase of the aerosol-generating product 10.

[0074] The connecting segment 11c is the part that connects the aerosol-generating matrix 11 and the filter 12; that is, the connecting segment 11c fixes the filter 12 by protruding into the inside of the filter 12, and the heating segment 11d corresponds to the exposed part 11b of the aerosol-generating matrix 11.

[0075] For example, as shown in Figures 3 and 9, the filter 12 includes a functional segment 121 having a filtering segment 1211 for filtering at least aerosols, and an outer coating layer 122 covering the outer circumferential side of the functional segment 121 and the outer circumferential side of the connecting segment 11c.

[0076] The functional segment 121 may be provided with only a filtration segment 1211 as shown in Fig. 3, or may be provided with both a filtration segment 1211 and a temperature-reducing segment 1212 as shown in Fig. 9. For functional segments 121 provided with a temperature-reducing segment 1212, by providing the temperature-reducing segment 1212 between the filtration segment 1211 and the aerosol-generating matrix 11, the aerosol is subjected to a temperature-reducing process before the filtration segment 1211 filters the aerosol, thereby lowering the temperature of the aerosol and improving the phenomenon of "burning the mouth" when the user inhales the aerosol.

[0077] Materials for the filtering segment 1211 include, but are not limited to, one or more combinations of PE (polyethylene), PLA (Polylactic acid, also known as polylactide), PBAT (butylene adipate-co-terephthalate), PP (Polypropylene), acetate fiber, and acrylic fiber materials.

[0078] The material of the temperature reducing segment 1212 includes, but is not limited to, one or more combinations of PE, PLA, PBAT, PP, acetate fiber, and acrylic fiber materials.

[0079] The materials of the temperature-reducing segment 1212 and the filtering segment 1211 may be the same or different.

[0080] It should be noted that the aerosol-generating product 10 relies on the aerosol-generating matrix 11 to generate the aerosol, and the functional segment 121 does not generate the aerosol.

[0081] The material of the outer coating layer 122 is not limited, but may include, for example, one or a combination of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE, PBAT, silicone rubber, etc.

[0082] 1 and 3, the functional segment 121 is spaced apart from the connecting segment 11c, and the side wall of the outer coating layer 122 may be provided with a second air passage 122a located in the space between the functional segment 121 and the connecting segment 11c and penetrating the side wall of the outer coating layer 122. During the user's inhalation process, the second air passage 122a allows external airflow to enter the filter 12 through the second air passage 122 due to negative pressure, causing the aerosol to flow in the direction of the user's inhalation.

[0083] In one embodiment, the aerosol-generating matrix 11 may have a mounting positioning portion 11e, as shown in Figure 2. The mounting positioning portion 11e may be used to position or fix the aerosol-generating device by fitting it to the aerosol-generating device, or in the case of an aerosol-generating product 10 provided with a filter 12, the mounting positioning portion 11e may be used to position or fix the filter 12 by fitting it to the filter 12.

[0084] 2 and 3, the mounting positioning portion 11e may be a mounting positioning hole that penetrates at least one end of the aerosol-generating matrix 11 along the first direction. For example, if the mounting positioning hole is simply used to fit into an aerosol-generating device for positioning or fixing, the mounting positioning hole may penetrate one end of the aerosol-generating matrix 11 that fits into the aerosol-generating device. In an aerosol-generating product 10 that includes a filter 12, if the mounting positioning hole is simply used to fit into the filter 12 for positioning or fixing, the mounting positioning hole may penetrate one end of the aerosol-generating matrix 11 that fits into the filter 12. If the mounting positioning hole is used to fit into both the aerosol-generating device and the filter 12 for positioning or fixing, the mounting positioning hole may penetrate both ends of the aerosol-generating matrix 11 that are opposite to each other along the first direction. One end of the mounting positioning hole is used to fit into the aerosol generating device for positioning or fixing, and the other opposite end of the mounting positioning hole is used to fit into the filter 12 for positioning or fixing. Also, when the mounting positioning hole is simply used to fit into one of the aerosol generating device and the filter 12 for positioning or fixing, the mounting positioning hole can also penetrate both ends of the aerosol generating matrix 11 that are opposite to each other in the first direction.

[0085] Another embodiment of the present invention provides an aerosol-generating product unit, which, as shown in Figures 11 and 12, comprises a blister cover packaging container 20 and an aerosol-generating product 10 according to any one of the embodiments of the present invention enclosed within the blister cover packaging container 20.

[0086] The blister cover packaging container 20 is a container used for blister cover packaging, which is a packaging method in which a product is enclosed between a blister cover 21 formed from a transparent plastic sheet and a bottom plate 22 (made of paperboard, plastic film or sheet, aluminum foil, or a composite material of these).

[0087] One aerosol-generating product 10 is enclosed within the same blister-cover packaging 20. Alternatively, multiple aerosol-generating products 10 may be enclosed within the same blister-cover packaging 20, as shown in Figures 11 and 12.

[0088] Encapsulating the aerosol-forming product 10 within the blister-cover packaging 20 may serve purposes such as waterproofing, moisture protection, and preventing evaporation of the aerosol-forming matrix 11 over its shelf life.
