Description

Technical Field

[0001] This application relates to the field of smoke generation technology, and in particular to an aerosol generating article. Background Technology

[0002] Aerosol generating products generally produce aerosols by heating without combustion. Specifically, the aerosol generating product contains a matrix section loaded with an atomizing agent. The matrix section is heated by an external heat source, such as the heating component on the aerosol generating device, until it is heated to a level sufficient to release fragrance. The matrix section does not burn, but releases the atomizing agent through heating to form an aerosol.

[0003] To ensure that aerosol-generating products can produce sufficient aerosols, a large amount of atomizing agent is usually added to the matrix section. However, after long-term storage, excessive atomizing agent can easily precipitate out from the matrix section, thus affecting the taste and cleanliness of the aerosol-generating products. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide an article that has both sufficient atomizing agent and can effectively prevent the formation of aerosols from atomizing agent precipitation.

[0005] To achieve the above objectives, embodiments of this application provide an aerosol generating article, comprising:

[0006] Matrix segment;

[0007] An aerosol replenishment section, the aerosol replenishment section comprising a matrix and an atomizing agent attached to the matrix, the aerosol replenishment section being disposed at at least one end of opposite ends of the matrix section along a first direction of the aerosol-generated article.

[0008] In one embodiment, the substrate is a one-piece structure.

[0009] In one embodiment, the substrate is one of the following: injection molding structure, blow molding structure, extrusion molding structure, compression molding structure, rotational molding structure, thermoforming structure, transfer molding structure, reaction injection molding structure, gas-assisted injection molding structure, casting molding structure, and microcellular foaming structure.

[0010] In one embodiment, the substrate has an air passage comprising at least one of pores, cracks, and airflow channels, wherein the airflow channels extend through at least one end of the substrate at opposite ends along a first direction of the aerosol-generated article.

[0011] In one embodiment, the number of airflow channels is multiple;

[0012] The substrate has a first region passing through its center, and a plurality of airflow channels surround the outer periphery of the first region; or...

[0013] The plurality of airflow channels include a first channel located at the center of the substrate and at least two second channels surrounding the outer periphery of the first channel.

[0014] In one embodiment, the airflow channel is located inside or on the outer surface of the substrate; or,

[0015] The number of airflow channels is multiple, with some airflow channels located inside the substrate and others located on the outer surface of the substrate.

[0016] In one embodiment, at least a portion of the airflow channel along its extension direction is a curve with a non-zero curvature; or,

[0017] The airflow channel is a straight channel.

[0018] In one embodiment, the total volume of the gas path accounts for 2%-76% of the volume of the substrate.

[0019] In one embodiment, the content of the atomizing agent is 3%-40%.

[0020] In one embodiment, the aerosol replenishment section further includes a flavoring substance attached to the substrate.

[0021] In one embodiment, the matrix segment comprises a dispersed atomizing medium.

[0022] In one embodiment, the matrix segment further includes an atomizing agent attached to the atomizing medium, and the atomizing agent content in the aerosol replenishment segment is higher than the atomizing agent content in the matrix segment; and / or,

[0023] The atomizing medium is in the form of flakes, filaments, powder, or granules.

[0024] In one embodiment, the matrix segment further includes a flavoring substance; and / or,

[0025] The length of the aerosol replenishment segment along the first direction is smaller than the length of the matrix segment along the first direction.

[0026] In one embodiment, at least one of the aerosol replenishment segment and the matrix segment is exposed; or,

[0027] The aerosol-generating article includes a coating layer that wraps around the outer periphery of the aerosol replenishment section and the matrix section.

[0028] In one embodiment, the cross-section of the atomizing medium is circular, polygonal, elliptical, racetrack-shaped, or irregular.

[0029] This application provides an aerosol generating article comprising a matrix section and an aerosol replenishment section. Since the aerosol replenishment section can additionally hold the atomizing agent, the atomizing agent content in the matrix section of the aerosol generating article can be balanced by setting the aerosol replenishment section. This is equivalent to the atomizing agent, which was originally only set in the matrix section, being shared by the matrix section and the aerosol replenishment section. This can effectively prevent the atomizing agent in the matrix section from precipitating out due to excess, and also ensure that the aerosol generating article has a sufficient amount of atomizing agent.

[0041] In the description of the embodiments in this application, it should be noted that the orientation or positional relationship indicated by terms such as "first direction" is based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0042] This application provides an aerosol-generating article; please refer to [link / reference]. Figure 1 , Figure 3 and Figure 5 The aerosol-generating product includes a matrix section 10 and an aerosol replenishment section 20.

[0043] The matrix segment 10 includes an atomizing medium.

[0044] The aerosol replenishment section 20 includes a substrate 21 and an atomizing agent attached to the substrate 21.

[0045] The aerosol replenishment section 20 is disposed at at least one of the opposite ends of the matrix section 10 along the first direction of aerosol generation. Specifically, the opposite ends of the matrix section 10 along the first direction of aerosol generation are a proximal lip end and a distal lip end, respectively; the aerosol replenishment section 20 is disposed at at least one of the proximal lip end and the distal lip end.

[0046] The proximal end is the end closest to the user's mouth, while the distal end is the end furthest from the user's mouth.

[0047] The number of aerosol replenishment segments 20 can be one or more. When there is only one aerosol replenishment segment 20, it can be located near the lip of the matrix segment 10 or near the distal lip of the matrix segment 10. When there is more than one aerosol replenishment segment 20, all aerosol replenishment segments 20 can be located near the lip of the matrix segment 10, all aerosol replenishment segments 20 can be located near the distal lip of the matrix segment 10, or some aerosol replenishment segments 20 can be located near the lip of the matrix segment 10 and others can be located near the distal lip of the matrix segment 10.

[0048] The specific connection method between the aerosol replenishment section 20 and the matrix section 10 is not limited here. For example, the aerosol replenishment section 20 and the matrix section 10 can be physically bonded, chemically bonded, or riveted.

[0049] The matrix segment may also include an atomizing agent attached to the atomizing medium.

[0050] The atomizing agent in the aerosol replenishment section 20 and the atomizing agent in the matrix section 10 are heated and atomized by the heating element of the aerosol generating device to form an aerosol for users to inhale or for use in medicine, beauty, etc.

[0051] There are various heating methods for the heating element. For example, heating methods include center heating and peripheral heating. Center heating refers to the heating element being inserted into the matrix section 10 and / or aerosol replenishment section 20 to bake and heat the matrix section 10 and / or aerosol replenishment section 20. Peripheral heating refers to the heating element being positioned around the matrix section 10 and / or aerosol replenishment section 20 to bake and heat the matrix section 10 and / or aerosol replenishment section 20. These heating methods may specifically include resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc., and are not specifically limited here.

[0052] The components of the atomizing agent are not limited, and may include, for example, one or more combinations of: water; flavored natural extracts (such as palm oil, honey, coconut oil); monohydric alcohols (such as menthol); polyhydric alcohols (such as propylene glycol, glycerol, triethylene glycol, 1,3-butanediol, and glycerin); esters of polyhydric alcohols (such as glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate); monocarboxylic acids; polycarboxylic acids (such as lauric acid, myristic acid, malic acid, citric acid) or aliphatic esters of polycarboxylic acids (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl lauryl carbonate, trimethyl lauryl acetate, trimethyl glycerol diacetate mixture, diethyl octanoate, triethyl citrate, methyl benzoate, phenylacetic acid methyl ester, ethyl vanillate, triglyceride tributyl ester, and lauryl acetate).

[0053] The atomizing agent in the aerosol replenishment section 20 can have the same composition as the atomizing agent in the matrix section 10, or they can be different.

[0054] For example, the atomizing agent of the aerosol replenishment section 20 can be mainly honey, with a certain amount of polyol and polyester mixture added, and the atomizing agent of the matrix section 10 can be mainly water, with a certain amount of propylene glycol and glycerol added.

[0055] In some embodiments, the matrix segment 10 may further include flavoring agents, which serve to improve the flavor of the aerosol. Flavoring agents include, but are not limited to, biomass components and their extracts required to produce aerosol flavor.

[0056] In addition, the matrix segment 10 may also contain flavoring substances to modify the aerosol flavor, binders to maintain the shape of the matrix segment 10, functional substances to adjust the physicochemical properties of the matrix segment 10, and other functional substances to give the matrix segment 10 other functions, as needed.

[0057] The purpose of setting up the aerosol replenishment section 20 is to replenish the aerosol by balancing the atomizing agent content in the matrix section 10. This is equivalent to the atomizing agent that was originally only set in the matrix section 10 being shared by the matrix section 10 and the aerosol replenishment section 20. This can effectively prevent the atomizing agent in the matrix section 10 from precipitating out due to excess, and also ensure that the aerosol generated product has a sufficient amount of atomizing agent.

[0058] In addition, in related technologies, for aerosol-generated products with a matrix segment containing flavoring substances and other effective components, after long-term storage, excessive atomizing agents will extract the flavoring substances and other effective components, causing them to precipitate out, thereby leading to flavor degradation of the aerosol-generated product.

[0059] Since the aerosol generating product of this application embodiment is provided with an aerosol replenishment section 20 to replenish the atomizing agent, the content of the atomizing agent in the matrix section 10 of this application embodiment is relatively small compared with the matrix section in the related art, thereby better preventing the effective ingredients such as flavoring substances in the matrix section 10 from being extracted and precipitated by the atomizing agent.

[0060] The atomizing agent content of the matrix segment 10 can be adjusted according to specific design requirements. However, since some flavoring substances and other effective ingredients that are easily extracted by the atomizing agent may be added to the matrix segment 10, in order to minimize the extraction of flavoring substances and other effective ingredients in the matrix segment 10 by the atomizing agent, it is preferable that the atomizing agent content of the matrix segment 10 (i.e., the weight of the atomizing agent in the matrix segment 10 to the total weight of the matrix segment 10) is less than or equal to 2.1%. For example, the atomizing agent content of the matrix segment 10 can be 0.4%, 1%, 2.1%, etc.

[0061] The atomizing agent content in the aerosol replenishment section 20 can be adjusted according to specific design requirements. However, to better prevent excessive precipitation of atomizing agent in the aerosol replenishment section 20, it is preferable that the atomizing agent content (i.e., the weight of the atomizing agent in the aerosol replenishment section 20 relative to the total weight of the aerosol replenishment section 20) can be 3%-40% (including endpoint values). For example, the atomizing agent content in the aerosol replenishment section 20 can be 3%, 5%, 10%, 25%, 32%, 40%, etc. More preferably, the atomizing agent content in the aerosol replenishment section 20 can be 5%-32% (including endpoint values).

[0062] The atomizing agent content of the matrix section 10 and the atomizing agent content of the aerosol replenishment section 20 can be the same or different. However, since the main function of the aerosol replenishment section 20 is to replenish the atomizing agent, it is more preferable that the atomizing agent content of the aerosol replenishment section 20 can be higher than that of the matrix section 10.

[0063] Adjustments can be made according to specific design needs. In this embodiment, the sum of the atomizing agent content of the matrix section 10 and the atomizing agent content of the aerosol replenishment section 20 can be equal to, or greater than, or less than, the atomizing agent content of the aerosol-generating product in the related art. Furthermore, the aerosol replenishment section 20 can contain only the atomizing agent, or other substances can be added.

[0064] For example, the aerosol replenishment section 20 may also include a flavoring substance attached to the substrate 21.

[0065] The flavoring substances in the aerosol replenishment section 20 are also for improving the flavor of the aerosol. If the matrix section 10 also contains flavoring substances, the flavoring substances in the aerosol replenishment section 20 can be the same as or different from those in the matrix section 10.

[0066] When the flavoring substances in the aerosol replenishment section 20 are different from those in the matrix section 10, the heating element of the aerosol generating device can be used to heat only the aerosol replenishment section 20 to mainly release the flavoring substances in the aerosol replenishment section 20, or only the matrix section 10 to mainly release the flavoring substances in the matrix section 10. Alternatively, both the aerosol replenishment section 20 and the matrix section 10 can be heated simultaneously to release the flavoring substances in both sections. This allows the same aerosol-generated product to produce aerosols with different flavors, thereby enhancing the diverse experience of aerosol-generated products.

[0067] In addition, other substances can be added to the aerosol replenishment section 20, such as functional substances that can improve the structural hardness, thermal conductivity and other physicochemical properties of the aerosol replenishment section 20, functional substances that can assist the release of the atomizing agent, and functional substances that can give the aerosol replenishment section 20 special functions.

[0068] The length of the aerosol replenishment section 20 along the first direction can be adjusted according to specific design needs. In order to better prevent the aerosol-generated product from being too long along the first direction and affecting the user experience, the length of the aerosol replenishment section 20 along the first direction can be minimized as long as the total content of the atomizing agent in the aerosol-generated product meets the requirements. More preferably, the length of the aerosol replenishment section 20 along the first direction can be less than or equal to the length of the matrix section 10 along the first direction.

[0069] The matrix segment 10 and the aerosol replenishment segment 20 can be manufactured using different processes, so that the structure of the matrix segment 10 is different from that of the aerosol replenishment segment 20.

[0070] For example, the matrix segment 10 includes a dispersed atomizing medium and an atomizing agent attached to the atomizing medium.

[0071] Dispersed atomizing media refers to numerous scattered atomizing media that are gathered together by the constraints of other structures. The dispersed atomizing media itself cannot maintain a predetermined shape and structural strength, and requires the help of other structures (such as the encapsulation layer 30 below) to maintain a predetermined shape.

[0072] In one embodiment, the atomizing medium can be in the form of flakes, filaments, powder, or granules.

[0073] In other words, the matrix segment 10 is not a single-piece structure. The atomizing medium can be one or more of the following: sheet-like, filamentous, powdery, or granular forms.

[0074] The shape of the matrix segment 10 is not limited; for example, the matrix segment 10 can be columnar. The cross-sectional shape of the columnar matrix segment 10 can be circular, polygonal (including but not limited to triangles, squares, rhombuses, etc.), elliptical, racetrack-shaped, irregular, etc., wherein irregular refers to other symmetrical or asymmetrical shapes besides those listed above. In other words, the cross-section of the atomizing medium is circular, polygonal, elliptical, racetrack-shaped, or irregular.

[0075] In other embodiments, the matrix segment 10 may also be an integral structure.

[0076] To facilitate the manufacturing of the aerosol replenishment section 20, the substrate 21 can be an integral structure, which refers to a structure manufactured through an integral molding process.

[0077] For example, the substrate 21 may be an injection-molded structure processed by injection molding, a blow-molded structure processed by blow molding, an extrusion-molded structure processed by extrusion molding, a compression-molded structure processed by compression molding, a rotational molding structure processed by rotational molding, a thermoforming structure processed by thermoforming, a transfer molding structure processed by transfer molding, a reaction injection molding structure processed by reaction injection molding, a gas-assisted injection molding structure processed by gas-assisted injection molding, a casting structure processed by casting molding, a microcellular foaming structure processed by microcellular foaming, etc.

[0078] Whether the substrate 21 is an integral structure or a non-integral structure, the specific shape of the substrate 21 is not limited. For example, in some embodiments, the substrate 21 can be a structure with a uniform cross-section. A substrate 21 with a uniform cross-section is not only easy to process and manufacture, but also helps to improve the space utilization rate of aerosol generated products.

[0079] In other embodiments, the substrate 21 may also be a variable cross-section structure, which means that the dimensions of the substrate 21 vary along the first direction, that is, the dimensions of the substrate 21 at at least one location are not equal to the dimensions at other locations.

[0080] For example, please refer to Figures 1 to 7 The matrix 21 is columnar, spherical, conical, or frustum-shaped.

[0081] In one implementation, please refer to Figure 1 and Figure 2 The substrate 21 may have air passages, which include at least one of pores (not shown), cracks (not shown), and airflow channels 21a. Among them, pores and cracks are generally structures naturally formed in the substrate 21, while airflow channels 21a are structures formed by processing.

[0082] The purpose of providing an air passage in the substrate 21 is to allow aerosols to pass through, thereby increasing the aerosol flow rate.

[0083] To facilitate aerosol release and ensure that the substrate 21 can store a sufficient amount of atomizing agent, preferably, the total volume of the gas path can account for 2%-76% of the volume of the substrate 21 (including endpoint values). For example, the total volume of the gas path can account for 2%, 8%, 19%, 27%, 35%, 46%, 52%, 65%, 76% of the volume of the substrate 21, etc.

[0084] For an aerosol replenishment section having an airflow channel 21a, the airflow channel 21a penetrates at least one of the opposite ends of the substrate 21 along the first direction of the aerosol-generated article.

[0085] In other words, at least one end of the airflow channel 21a is open to the outside along the first direction. For example, the airflow channel 21a extends into the substrate 21 from the open end, and can extend to a certain depth of the substrate 21 but does not penetrate the substrate 21. That is, one end of the airflow channel 21a penetrates the substrate 21 and the other end is a closed end. Alternatively, the airflow channel 21a can also penetrate the substrate 21 at opposite ends along the first direction.

[0086] Compared to the airflow channel 21a passing through one end of the aerosol replenishment section 20, the airflow channel 21a passing through both ends of the aerosol replenishment section 20 is more conducive to reducing the suction resistance of the user's suction.

[0087] The shape of the cross-section of the airflow channel 21a is not limited. For example, the shape of the cross-section can be circular, polygonal (including but not limited to triangle, square, rhombus, etc.), elliptical, runway-shaped, or irregular.

[0088] The number of airflow channels 21a can be one or more.

[0089] For example, an airflow channel 21a may extend through the center of the base 21.

[0090] In some heating methods, aerosols will first flow out from the central area of ​​the aerosol replenishment section 20 (such as the aerosol replenishment section 20 heated by the central heating method). For this type of aerosol replenishment section 20, the airflow channel 21a penetrates the center of the substrate 21, which allows the aerosols to enter the airflow channel 21a in a timely manner, thereby improving the aerosol extraction efficiency.

[0091] When there are multiple airflow channels 21a, in one embodiment, please refer to [reference needed]. Figure 6 The substrate 21 has a first region Z passing through the center of the substrate 21 (i.e., Figure 6 (The area within the dashed circle) has multiple airflow channels 21a surrounding the outer periphery of the first area, meaning that the airflow channels 21a can avoid the center of the base 21.

[0092] Multiple airflow channels 21a can be arranged in a single loop or in multiple loops.

[0093] In some heating methods, aerosols will first flow out from near the outer wall of the aerosol replenishment section 20 (such as the aerosol replenishment section 20 heated by a peripheral heating method). For this type of aerosol replenishment section 20, multiple airflow channels 21a surround the outer periphery of the first region of the substrate 21, which can enable aerosols to enter the airflow channels 21a in a timely manner, thereby improving the aerosol extraction efficiency.

[0094] In another implementation, please refer to Figure 7 The multiple airflow channels 21a may include a first channel 21a1 located at the center of the substrate 21 and at least two second channels 21a2 surrounding the outer periphery of the first channel 21a1.

[0095] In other words, the number of airflow channels 21a can be at least three. For ease of description, the airflow channel 21a that penetrates the center of the substrate 21 is called the first channel 21a1, and the airflow channel 21a located on the outer periphery of the first channel 21a1 is called the second channel 21a2.

[0096] Under certain heating methods, aerosols can flow out more evenly from various parts of the aerosol replenishment section 20. Therefore, one of the airflow channels 21a on the substrate 21 penetrates the center of the substrate 21, while the other airflow channels 21a are located on the outer periphery of the airflow channel 21a that penetrates the center of the substrate 21. This allows the aerosols flowing out from various parts of the aerosol replenishment section 20 to enter the airflow channel 21a in a timely manner, thereby improving the aerosol extraction efficiency.

[0097] In other embodiments, the multiple airflow channels 21a may also be randomly distributed, or as follows: Figure 8 and Figure 9 The distribution shown follows other patterns.

[0098] Please see Figure 1 , Figure 3 , Figures 6 to 9 The airflow channel 21a can be located inside the substrate 21. In other embodiments, the airflow channel 21a can also be located on the outer surface of the substrate 21.

[0099] When there are multiple airflow channels 21a, all airflow channels 21a may be located inside the base 21, all airflow channels 21a may be located on the outer surface of the base 21, or some airflow channels 21a may be located inside the base 21 and other airflow channels 21a may be located on the outer surface of the base 21.

[0100] For the airflow channel 21a located on the outer surface of the substrate 21, the airflow channel 21a is actually a groove-shaped structure that passes through the outer surface of the substrate 21. In actual use, a wrapping layer 30 or a tube can be provided around the outer surface of the substrate 21. As a result, the slot of the airflow channel 21a facing the inner wall of the wrapping layer 30 or the tube will be blocked by the inner wall, so that the aerosol can still flow along the airflow channel 21a.

[0101] In some embodiments, please refer to Figure 1 and Figure 3 The airflow channel 21a can be a straight channel, which is an airflow channel 21a that extends in a straight line, or in other words, the direction of extension of the straight channel is a straight line.

[0102] In other embodiments, the airflow channel 21a may also be a curve with a non-zero curvature in at least a portion of the extended region.

[0103] In other words, the airflow channel 21a can be a spiral channel. Along the extension direction of the spiral channel, the spiral channel can have a structure with both curved segments with non-zero curvature and straight segments with zero curvature, or it can have a structure with only curved segments with non-zero curvature and no straight segments with zero curvature. That is to say, from the starting point to the ending point of the spiral channel along the extension direction, the spiral channel only needs to not extend in a straight line.

[0104] When there are multiple airflow channels 21a, all airflow channels 21a can be straight airways, all airflow channels 21a can be spiral channels, or some airflow channels 21a can be straight airways and other airflow channels 21a can be spiral channels.

[0105] In one implementation, please refer to Figure 1 and Figure 3 The aerosol-generating article may include a coating layer 30, which is wrapped around the outer periphery of the aerosol replenishment section 20 and the matrix section 10.

[0106] In other embodiments, the coating layer 30 may only coat the aerosol replenishment segment 20 while leaving the matrix segment 10 exposed, or it may only coat the matrix segment 10 while leaving the aerosol replenishment segment 20 exposed.

[0107] In other embodiments, please refer to Figure 5 Alternatively, both the aerosol replenishment section 20 and the matrix section 10 can be exposed without a wrapping layer 30.

[0108] In one implementation, please refer to Figures 1 to 5 The aerosol-generating article may also include a functional segment 40. The functional segment 40 may be disposed at the proximal and / or distal lip ends of the matrix segment 10, depending on its function.

[0109] The wrapping layer 30 may also wrap at least part of the outer periphery of the functional segment 40.

[0110] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 5 Functional segment 40 includes a filter segment 41, which is disposed near the lip end of matrix segment 10. When aerosol replenishment segment 20 is disposed near the lip end of matrix segment 10, aerosol replenishment segment 20 is located between filter segment 41 and matrix segment 10.

[0111] The filter section 41 is used to come into contact with the user's mouth during inhalation to filter large particles in the aerosol and to cool the aerosol.

[0112] The materials of the filter section 41 include, but are not limited to, one or more combinations of PE, PLA (Polylactic acid), PBAT, PP (Polypropylene), cellulose acetate, and propylene fiber.

[0113] In other embodiments, functional segment 40 may also be without filter segment 41. For example, the aerosol generating device may be equipped with a nozzle that can be reused or used only once. The nozzle is used in conjunction with an aerosol generating product without filter segment 41 to replace filter segment 41.

[0114] In some embodiments, please refer to Figure 3 and Figure 5 The functional segment 40 may include a cooling segment 42, which is located near the lip of the matrix segment 10. The aerosol is cooled as it passes through the cooling segment 42. When the aerosol replenishment segment 20 is located near the lip of the matrix segment 10, the aerosol replenishment segment 20 is generally situated between the cooling segment 42 and the matrix segment 10. The cooling segment 42 can abut against and support the adjacent matrix segment 10 or aerosol replenishment segment 20, preventing the matrix segment 10 or aerosol replenishment segment 20 from moving towards the lip.

[0115] The near-lip end of the matrix section 10 can be provided with both a cooling section 42 and a filter section 41, with the filter section 41 located on the side of the cooling section 42 away from the matrix section 10.

[0116] In some other embodiments, the cooling section 42 may be omitted.

[0117] In some embodiments, please refer to Figure 3 and Figure 5 The functional segment 40 may include a pre-plug segment 43, which is disposed at the distal lip end of the matrix segment 10. The pre-plug segment 43 can prevent the matrix segment 10 from shrinking and falling off after heating and from adsorbing backflowing aerosols. When the aerosol replenishment segment 20 is disposed at the distal lip end of the matrix segment 10, the aerosol replenishment segment 20 is located between the pre-plug segment 43 and the matrix segment 10.
