Description

Technical Field

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

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material could be tobacco or other non-tobacco products, which may or may not contain nicotine.

[0004] Aerosol generating devices can atomize aerosol products such as cigarettes to form smoke. The smoke contains a large amount of nicotine and flavor, which can well satisfy the habitual needs of smokers.

[0005] Currently, there is an aerosol generating product on the market that includes a columnar matrix section and a filter section. Aerosols can be generated by heating the matrix section. However, because the matrix is ​​piled up together, this type of aerosol generating product requires a relatively long preheating time. Utility Model Content

[0006] To address the issue of the relatively long preset time for aerosol generation articles, the first embodiment of this application provides an aerosol generation article.

[0007] The support assembly includes multiple support plates, which are sequentially arranged end to end to form an airflow channel;

[0008] A matrix assembly, including a matrix sheet disposed on the support plate;

[0009] In the circumferential direction of the airflow channel, both sides of the support plate are provided with connecting parts, and any two adjacent support plates are connected through the corresponding connecting parts.

[0010] A second embodiment of this application provides an aerosol generation system, including the aerosol generation article described in any one of the above-mentioned embodiments, and

[0011] The aerosol generating device has a heating chamber;

[0012] The aerosol generating product is removable and inserted into the heating chamber, where it generates aerosol under heating.

[0013] Through the above methods: This application provides an aerosol generating article and an aerosol generating system, including a support component and a matrix component. The support component includes multiple support plates that enclose and form an airflow channel. By setting matrix sheets on the support plates, the preheating time can be reduced compared to stacking matrix materials together. Furthermore, by setting connecting parts on both sides of the support plates to cooperate with other support plates, the connection stability between the support plates of the support components can be improved, thereby improving the strength of the entire aerosol generating article.

[0044] Please see Figures 1-25 This application provides an aerosol generating article 10, which includes a support component 100 and a matrix component 200.

[0045] In some embodiments, the aerosol generating article 10 includes a support plate 110 and a matrix sheet 210.

[0046] In some embodiments, the support component 100 includes a plurality of support plates 110, and the plurality of support plates 110 can be enclosed to form an elongated cavity 120.

[0047] In some embodiments, the aerosol generating article 10 includes a plurality of support plates 110, and the plurality of support plates 110 are connected end to end to form an elongated cavity 120.

[0048] In some embodiments, each support plate 110 is provided with an exposure window 131 that connects to the elongated cavity 120.

[0049] In some embodiments, the substrate sheet 210 may be specifically attached to the support plate 110, and at least a portion of the substrate sheet 210 may be exposed through the exposure window 131.

[0050] In some embodiments, the substrate sheet 210 is heated to generate an aerosol, which can overflow from the exposure window 131 into the elongated cavity 120.

[0051] In some embodiments, each support plate 110 is provided with a plurality of exposure windows 131, and the plurality of exposure windows 131 are arranged in the length direction of the elongated cavity 120.

[0052] In some embodiments, the matrix sheet 210 is also provided on the support plate 110 in multiple ways.

[0053] In some embodiments, the elongated cavity 120 has a proximal end 121 and a distal end 122 facing away from each other.

[0054] The proximal end 121 is the end of the aerosol-generating product 10 that is closest to the user during use, and may specifically be the end used for inhalation. The distal end 122 is the end that can abut against the aerosol-generating device 20, and may be supported on the aerosol-generating device 20.

[0055] In some embodiments, the cross-section of the elongated cavity 120 may be polygonal, specifically a triangle, quadrilateral, pentagon or other polygon, which is not limited here.

[0056] like Figure 2 and Figure 3 As shown, the support plate 110 is in the shape of a long plate. The two long sides of any one of the multiple support plates 110 are connected to the long sides of the other support plate 110 respectively, so that the multiple support plates 110 form an enclosed structure and enclose a long cavity 120.

[0057] In some embodiments, the plurality of support plates 110 may be three, and the three support plates 110 are connected to each other in pairs to form an elongated cavity 120 with a triangular cross-section.

[0058] In some embodiments, the support plate 110 may also be an arc-shaped plate, and multiple support plates 110 are integrally formed to enclose an elongated cavity 120 with a circular / elliptical cross-section.

[0059] In some embodiments, multiple support plates 110 are integrally formed and enclosed to form a tubular structure.

[0060] In some embodiments, the plurality of support plates 110 may be four, and the four support plates 110 are connected in sequence to form an elongated cavity 120 with a quadrilateral cross-section.

[0061] In some embodiments, the matrix assembly 200 includes a matrix sheet 210, which may be disposed on at least two support plates 110. For example, if there are multiple support plates 110, specifically three, the matrix sheet 210 may be disposed on two or three support plates 110. If there are multiple support plates 110, specifically four, the matrix sheet 210 may be disposed on two, three, or four support plates 110, and no limitation is made here.

[0062] In some embodiments, the support plate 110 is provided with an exposure window 131 that communicates with the elongated cavity 120 and is used to expose at least a portion of the substrate sheet 210. That is, the support plate 110 is provided with an exposure window 131 that exposes the substrate sheet 210 in the elongated cavity 120, so that the substrate sheet 210 can communicate with the elongated cavity 120. Specifically, the main surface of the substrate sheet 210 can communicate with the elongated cavity 120.

[0063] In some embodiments, the exposure window 131 is disposed opposite to the substrate sheet 210.

[0064] In some embodiments, the aerosol generating article 10 can form an aerosol under the heating of the aerosol generating apparatus 20.

[0065] In some embodiments, the aerosol generating apparatus 20 may include a heating chamber 21, into which the aerosol generating article 10 is removably inserted, such that the substrate sheet 210 can form an aerosol in the heating chamber 21, and due to the exposure window 131, the aerosol generated by the substrate sheet 210 can enter the elongated cavity 120 through the exposure window 131.

[0066] In some embodiments, the aerosol-generating article 10 may be a tobacco-containing material from which volatile compounds are released upon heating from the matrix sheet 210; or it may be a non-tobacco material suitable for post-heat smoking. The matrix sheet 210 may be a solid matrix, which may include one or more of the following: vanilla leaves, tobacco leaves, homogenized tobacco, expanded tobacco, powder, granules, fragments, strips, or sheets; or the matrix sheet 210 may contain additional tobacco or non-tobacco volatile flavor compounds to be released upon heating of the matrix sheet 210.

[0067] In the above embodiments, an aerosol generating article 10 is provided, including a support assembly 100 and a matrix assembly 200. The support assembly 100 includes a plurality of support plates 110, which enclose an elongated cavity 120. The matrix assembly 200 includes a matrix sheet 210 disposed on at least two support plates 110. The support plates 110 are provided with an exposure window 131 that communicates with the elongated cavity 120 and exposes at least a portion of the matrix sheet 210. By disposing the matrix sheet 210 on at least two support plates 110, compared to disposing the matrix sheet 210 on only one support plate 110, the layout density of the matrix sheet 210 can be effectively increased, thereby improving the durability of the aerosol generating article 10. Furthermore, by setting the matrix assembly 200 to matrix sheets 210 separated by the elongated cavity 120, while ensuring the total amount of material in the matrix assembly 200, the material volume / thickness of a single matrix sheet 210 is reduced, making it easier and faster to achieve heating, thereby achieving better smoke emission and reducing smoke emission time.

[0068] In some embodiments, the support plate 110 may be a rectangular strip, which can be connected in pairs by the long strip edges to form an enclosed structure with a long cavity 120.

[0069] In some embodiments, the cross-section of the elongated cavity 120 is triangular, that is, the cross-section of the elongated cavity 120 perpendicular to the length direction is triangular. Optionally, the support assembly 100 includes three support plates 110 to enclose the elongated cavity 120 with a triangular cross-section.

[0070] In some embodiments, the cross-section of the elongated cavity 120 may be an equilateral triangle. Optionally, the support assembly 100 includes three support plates 110 of equal width to enclose the elongated cavity 120 with an equilateral triangle cross-section.

[0071] In some embodiments, a matrix sheet 210 may be provided on each of the three support plates 110.

[0072] In some embodiments, the cross-section of the elongated cavity 120 may be a right-angled isosceles triangle. Optionally, the support assembly 100 includes at least two support plates 110 of equal width to enclose the elongated cavity 120 with a cross-section of a right-angled isosceles triangle.

[0073] In some embodiments, a matrix sheet 210 is provided on two support plates 110 corresponding to the two right-angled sides of a right-angled isosceles triangle.

[0074] In some embodiments, the cross-section of the elongated cavity 120 may also be rectangular. Optionally, the support assembly 100 includes four support plates 110, and there are two sets of support plates 110 of equal width in pairs, thereby enclosing and forming an elongated cavity 120 with a rectangular cross-section.

[0075] In some embodiments, the cross-section of the elongated cavity 120 may also be pentagonal or hexagonal, and the corresponding matrix component 200 may also include five or six support plates 110, which is not limited here.

[0076] In some embodiments, a matrix sheet 210 is provided on two opposing support plates 110.

[0077] In some embodiments, a substrate sheet 210 is provided on two wider support plates 110, which can increase the mounting volume of the substrate sheet 210, thus increasing the volume of the substrate sheet 210 is advantageous.

[0078] In some embodiments, the elongated cavity 120 has a square cross-section. Optionally, the support assembly 100 includes four support plates 110 of equal width, thereby enclosing and forming the elongated cavity 120 with a square cross-section.

[0079] In some embodiments, a matrix sheet 210 is provided on each of the four support plates 110, which can greatly increase the density of the matrix sheet 210, increase the service life of the entire aerosol generating product 10, and allow the matrix sheet 210 on each support plate 110 to be heated independently, thereby effectively reducing the heating time.

[0080] In some embodiments, such as Figure 14 As shown, the matrix sheet 210 can be sheet-like and may include a connected aerosol matrix layer 211 and a receptor layer 212. Specifically, the aerosol matrix layer 211 may include one or more of the following: vanilla leaves, tobacco leaves, homogenized tobacco, expanded tobacco, powders, granules, fragments, strips, or sheets, and will generate an aerosol upon heating. Optionally, the receptor layer 212 can be heated in a changing magnetic field, thereby heating the aerosol matrix layer 211 to form an aerosol.

[0081] In some embodiments, an aerosol matrix layer 211 is stacked on the surface of a receptor layer 212, and the receptor layer 212 is used to heat the aerosol matrix layer 211 to generate aerosols under the action of a magnetic field.

[0082] In some embodiments, the receptor layer 212 may include a perforated structure to prevent aerosols generated by the aerosol matrix layer 211 from being blocked by the receptor layer 212.

[0083] In some embodiments, the receptor layer 212 has a plurality of perforations, which may specifically be through holes, so that the aerosol generated by the aerosol atmosphere layer 211 can pass through the perforations.

[0084] In some embodiments, the receptor layer 212 is located on the side of the aerosol matrix layer 211 facing the elongated cavity 120, so that the receptor layer 212 can heat the surface of the aerosol matrix layer 211 facing the elongated cavity 120, so that the aerosol generated by heating can enter the elongated cavity better.

[0085] In some embodiments, the aerosol generating device 20 can generate a changing magnetic field in the heating chamber 21 to heat the receptor layer 212 in the matrix sheet 210, so that the receptor layer 212 can heat the aerosol matrix layer 211 to form an aerosol.

[0086] In some embodiments, a plurality of substrate sheets 210 may be provided on a support plate 110, and the plurality of substrate sheets 210 may be arranged at intervals along the length direction of the support plate 110.

[0087] In some embodiments, the substrate sheet 210 may be in the form of a circular sheet structure.

[0088] In some embodiments, the substrate sheet 210 may also be a rectangular sheet structure, and this is not limited here.

[0089] In some embodiments, the multiple support plates 110 can be integrally formed. Optionally, the multiple support plates 110 can be formed by multiple folding of a support substrate. If there are three support plates 110, they can be formed by folding the support substrate twice or three times, so that at least a portion of one support plate 110 has twice the thickness of the other support plates 110, which is beneficial for the final connection of the entire support assembly 100.

[0090] In some embodiments, the support substrate may be a high-strength cardboard, which is not limited here.

[0091] In other embodiments, the support substrate may also be a plate structure formed of other biodegradable materials.

[0092] In some embodiments, such as Figure 20 As shown, the support plate 110 includes a first plate 140 and a second plate 150 connected to the first plate 140. The second plate 150 is located on the side of the first plate 140 facing the elongated cavity 120, that is, the second plate 150 is located inside the first plate 140. The first plate 140 and the second plate 150 can be fitted together, such as by gluing or by fixing with clips. Optionally, the first plate 140 and the second plate 150 can also be spaced apart, which is not limited here.

[0093] In some embodiments, the first plate 140 has a receiving cavity 141 for receiving a matrix sheet 210, the receiving cavity 141 being able to receive at least a portion of the matrix sheet 210, such that the matrix sheet 210 can be positioned relatively securely on the first plate 140.

[0094] In some embodiments, the substrate sheet 210 is adapted to the receiving cavity 141 such that when the substrate sheet 210 is located in the receiving cavity 141, at least a portion of the side of the substrate sheet 210 is abutted by the first plate 140, so that the substrate sheet 210 can be limited in the circumferential direction by the first plate 140.

[0095] In some embodiments, such as Figure 8 As shown, the second plate 150 has an exposure window 131 for exposing the matrix sheet 210 located in the receiving cavity 141, and can expose at least a portion of the main surface of the matrix sheet 210. This allows the matrix sheet 210 to be exposed in the elongated cavity 120 (airflow channel), enabling aerosols formed when the matrix sheet 210 is heated to enter the elongated cavity 120 (airflow channel) via the exposure window 131. In some embodiments, an isolation layer (not shown) is provided on the surfaces of the second plate 150 facing the first plate 140 and away from the first plate 140 (i.e., facing the elongated cavity 120). This isolation layer can be used to prevent aerosol intrusion, thereby reducing the absorption of aerosols by the second plate 150 and ensuring the concentration of aerosols.

[0096] In some embodiments, the main surface of the substrate sheet 210 is the surface facing the elongated cavity 120.

[0097] In some embodiments, the second plate 150 covers at least a portion of the substrate sheet 210, that is, the portion of the main surface of the substrate sheet 210 exposed by the exposure window 131 is smaller than the main surface of the substrate sheet 210. In other words, the second plate 150 can axially limit the substrate sheet 210, thereby allowing the second plate 150 to cooperate with the first plate 140 to fix the substrate sheet 210, thereby fixing the substrate sheet 210 in the receiving cavity 141.

[0098] In some embodiments, the second plate 150 may abut against the substrate sheet 210.

[0099] Optionally, the substrate sheet 210 is fixed by the second plate 150 and the first plate 140. Compared with directly fixing the substrate sheet 210 to the receiving cavity 141 with glue, the glue can be heated during heating and generate gas that affects the taste of the aerosol, thus effectively improving the user experience.

[0100] In some embodiments, such as Figure 10As shown, the second plate 150 includes an adhesive portion 151 and an exposed portion 152 that are connected to each other, and the exposed portion 152 is disposed opposite to the substrate sheet 210.

[0101] In some embodiments, the display window 131 may include a plurality of sub-windows.

[0102] In some embodiments, the exposure portion 152 has an exposure window 131 and an abutment portion 153 for covering at least a portion of the substrate sheet 210.

[0103] In some embodiments, the abutment portion 153 is disposed at least partially opposite to the main surface of the substrate sheet 210.

[0104] In some embodiments, the projection of the abutment portion 153 onto the plane containing the main surface of the substrate sheet 210 is located within the main surface of the substrate sheet 210.

[0105] In some embodiments, the abutment portion 153 and the substrate sheet 210 may be spaced apart, which can be used to limit the formation of the substrate sheet 210 to prevent the substrate sheet 210 from leaving the receiving cavity 141.

[0106] In some embodiments, the abutment portion 153 may also directly abut against the substrate sheet 210 to prevent the substrate sheet 210 from shaking.

[0107] In some embodiments, the abutting portion 153 may be integrally formed with the fitting portion 151 and is formed by extending the fitting portion 151 toward the exposure window 131.

[0108] In some embodiments, the abutment portion 153 may be a horizontal or vertical strip spanning the display window 131.

[0109] In some embodiments, the abutment portion 153 may be a horizontal and vertical bar that are arranged in an intersecting manner across the display window 131.

[0110] In some embodiments, the substrate sheet 210 can be rectangular, specifically, the main surface of the substrate sheet 210 is rectangular, the exposed portion 152 can be a rectangle adapted to the substrate sheet 210, and its abutting portion 153 is a right-angled triangular structure provided at the four corners of the rectangle, so that the exposed window 131 is octagonal, that is, the orthographic projection of the exposed window 131 on the main surface of the substrate sheet 210 is octagonal. Specifically, the exposed window 131 can be formed by cutting a groove in the part of the second plate 150 opposite to the substrate sheet 210 (i.e., the exposed portion 152). In this way, it can be ensured that the main surface of the substrate sheet 210 and the elongated cavity 120 have sufficient exposed area, so that the aerosol generated by the substrate sheet 210 can smoothly enter the elongated cavity 120, and the abutting portion 153 and the bonding portion 151 are integrally formed, which can enhance the abutting strength of the abutting portion 153.

[0111] In some embodiments, the substrate sheet 210 can be circular, the exposed portion 152 can be a circle adapted to the substrate sheet 210, the exposed window 131 can be a circle with a radius smaller than the radius of the substrate sheet 210, and the abutting portion 153 can be an annulus.

[0112] In some embodiments, the fitting portion 151 is connected to the first plate 140.

[0113] In some embodiments, the orthographic projection of the exposure window 131 onto the main surface of the substrate 210 is concentric with the main surface.

[0114] In some embodiments, the substrate 210 may be circular, the exposed portion 152 may be a circle adapted to the substrate 210, and its exposed window 131 may be an embedded polygon. For example, the exposed window 131 may be an embedded square, an embedded hexagon, or an embedded octagon in the main surface of the substrate 210, which is not limited here.

[0115] In some embodiments, the ratio of the area of ​​the main surface of the substrate 210 exposed by the exposure window 131 to the area of ​​the main surface of the substrate 210 is greater than or equal to 60%, specifically 60%, 70%, or 80%. That is, the orthographic projection area of ​​the exposure window 131 on the main surface of the substrate 210 accounts for greater than or equal to 60% of the area of ​​the main surface, specifically 60%, 70%, or 80%.

[0116] In some embodiments, the ratio of the main surface area of ​​the substrate 210 exposed by the exposure window 131 to the main surface area of ​​the substrate 210 is greater than or equal to 80%.

[0117] In some embodiments, the ratio of the main surface area of ​​the substrate 210 exposed by the exposure window 131 to the main surface area of ​​the substrate 210 is greater than or equal to 85%.

[0118] In some embodiments, the ratio of the main surface area of ​​the substrate 210 exposed by the exposure window 131 to the main surface area of ​​the substrate 210 is greater than or equal to 90%.

[0119] In some embodiments, the ratio of the main surface area of ​​the substrate 210 exposed by the exposure window 131 to the main surface area of ​​the substrate 210 is less than or equal to 95%.

[0120] In the above embodiments, by ensuring the exposure area ratio of the exposure window 131, that is, limiting the contact ratio between the contact portion 153 and the substrate sheet 210, on the one hand, the obstruction of the aerosol generated by the contact portion 153 on the substrate sheet 210 can be reduced, and on the other hand, the substrate sheet 210 is prevented from transferring too much heat to the second plate 150 through the contact portion 153 after being heated, which would cause the second plate 150 to produce a burnt taste that affects the taste of the aerosol.

[0121] In some embodiments, the orthographic projection of the exposed portion 152 onto the plane containing the main surface of the substrate 210 can be greater than or less than the area of ​​the main surface of the substrate 210.

[0122] In some embodiments, the abutting portion 153 is integrally formed with the fitting portion 151 and is formed by extending the fitting portion 151 toward the exposure window 131.

[0123] In some embodiments, the second plate 150 of the plurality of support plates 110 is integrally formed, that is, all the second plate 150s in the entire support assembly 100 are integrally formed.

[0124] In some embodiments, the second plate body 150 of the plurality of support plates 110 can form the skeleton of the entire aerosol generating article 10.

[0125] In some embodiments, such as Figure 9 , Figures 15-17 As shown, at least three second plates 150 can be formed by folding the plate substrate 300.

[0126] In some embodiments, the substrate 300 may be cardboard or a plate-like structure with a certain strength made of other biodegradable materials.

[0127] In some embodiments, the substrate 300 includes a plurality of folding plates 310 in sequence along the folding direction, and a folding groove 320 is provided between adjacent folding plates 310. Adjacent folding plates 310 can be folded through the folding groove 320. This can effectively determine the folding position and ensure the convenience of folding, and reduce the problem of uneven corners caused by folding.

[0128] In some embodiments, there are four support plates 110, and there may also be four corresponding second plates 150.

[0129] In some embodiments, among the multiple support plates 110 connected in sequence, the support plates 110 located at the beginning and end are stacked. For example, if there are four support plates 110, the first and last support plates 110 of the four support plates 110 can be connected end to end and overlapped to form a long cavity with a triangular cross-section.

[0130] In some embodiments, among the multiple support plates 110 connected in sequence, the support plates 110 located at the beginning and end positions are stacked. For example, if there are four support plates 110, the first and last support plates 110 can be connected end to end to form an elongated cavity with a triangular cross-section. If there are five support plates 110, the first and last support plates 110 can be connected end to end to form an elongated cavity with a quadrilateral cross-section.

[0131] In some embodiments, the aerosol generating article 10 further includes a reinforcing plate 160, which may be attached to at least one support plate 110.

[0132] In some embodiments, the reinforcing plate 160 may be attached to one of a plurality of support plates 110, and the stacked head and tail support plates 110 are arranged opposite to each other.

[0133] In some embodiments, the reinforcing plate 160 is attached to the surface of the support plate 110 located between the first and last support plates 110.

[0134] In some embodiments, the reinforcing plate 160 and the support plate 110 have similar shapes.

[0135] In some embodiments, the reinforcing plate 160 is attached to the surface of the support plate 110 facing the elongated cavity 120.

[0136] In some embodiments, the plate substrate 300 includes four folding plates 310 in sequence along the folding direction. There are folding grooves 320 between adjacent folding plates 310. The number of folding grooves 320 is one less than the number of folding plates 310. For example, if there are four folding plates 310, there are three folding grooves. The folding plates 310 are folded three times through the three folding grooves 320, thereby forming a rectangular enclosure structure with connected ends. The four folding plates 310 respectively form the four second plates 150 of the support assembly 100.

[0137] In some embodiments, the substrate 300 includes five folding plates 310 sequentially along the folding direction. Folding grooves 320 are provided between adjacent folding plates 310, allowing the folding plates 310 to be folded four times. This results in the first and last folding plates 310 fitting together, thus better connecting the multiple second plates 150. The first and last folding plates 310 together form one second plate 150, while the other three folding plates 310 each form an independent second plate 150. When the last folding plate 310 fits against the first folding plate 310, it can be located either on the outer side of the first folding plate 310 (i.e., the side away from the elongated cavity 120) or on the inner side of the first folding plate 310 (i.e., the side closer to the elongated cavity 120).

[0138] In some embodiments, the lengths of the first folding plate 310, the second folding plate 310, the third folding plate 310, and the fifth folding plate 310 may be the same, and the length of the fourth folding plate 310 may be greater than the length of the fifth folding plate 310 by a preset distance.

[0139] In some embodiments, the first folding plate 310 and the last folding plate 310 can be fixed together by dispensing adhesive.

[0140] In some embodiments, along the folding direction, the length of the fourth folding plate 310 among the five folding plates 310 is greater than the length of the last folding plate 310 by a predetermined distance, so that when the last folding plate 310 is folded back, it can avoid the first folding plate 310.

[0141] In some embodiments, the folding angle of adjacent folding plates 310 can be 90 degrees, so that the plate substrate 300 forms a rectangular enclosure structure after folding.

[0142] In some embodiments, the preset distance may specifically be the thickness of the folding plate 310.

[0143] In some embodiments, the folding groove 320 may be in the form of a "V" groove.

[0144] In some embodiments, the folding groove 320 includes opposing first groove surfaces 321 and second groove surfaces 322.

[0145] In some embodiments, the first groove surface 321 and the second groove surface 322 are arranged in a "V" shape.

[0146] In some embodiments, the folding groove 320 extends along a straight line. In some embodiments, the extending direction of the folding groove 320 is the same as the folding direction.

[0147] In some embodiments, when the substrate is in an unfolded state, the included angle between the first groove surface and the second groove surface is greater than or equal to 85 degrees and less than or equal to 95 degrees. In some embodiments, when the substrate is in an unfolded state, the included angle between the first groove surface and the second groove surface is greater than or equal to 88 degrees and less than or equal to 92 degrees.

[0148] In some embodiments, the included angle between the first groove surface 321 and the second groove surface 322 is a right angle.

[0149] In some embodiments, the substrate 300 includes a first surface 340 and a second surface 350, the folding groove 320 is formed by the indentation of the first surface 340, and the second surface 350 is disposed opposite to the first surface 340.

[0150] In some embodiments, the angle between the first groove surface 321 and the second groove surface 322 and the second surface 350 is greater than or equal to 43 degrees and less than or equal to 47 degrees. In some embodiments, the angle between the first groove surface 321 and the second groove surface 322 and the second surface 350 is 45 degrees.

[0151] In some embodiments, the depth of the folding groove 320 is greater than or equal to 0.1 mm and less than or equal to 0.3 mm, specifically 0.1 mm, 0.2 mm or 0.3 mm.

[0152] In some embodiments, the first groove surface 321 and the second groove surface 322 are fitted together after folding.

[0153] In some embodiments, the support assembly 100 further includes a reinforcing plate 160, which may be specifically connected to the side of the support plate 110 near the elongated cavity 120.

[0154] In some embodiments, the reinforcing plate 160 and the support plate 110 may be fitted together.

[0155] In some embodiments, the reinforcing plate 160 and the support plate 110 can be attached to the support plate 110 by means of adhesive or by means of clips.

[0156] In some embodiments, the reinforcing plate 160 may be a single plate and connected to one of the plurality of support plates 110.

[0157] In some embodiments, there may be two reinforcing plates 160, and the two reinforcing plates 160 are connected to two opposite support plates 110 among the plurality of support plates 110. For example, the plurality of support plates 110 may specifically be four, and the two reinforcing plates 160 are connected to two non-adjacent support plates 110, that is, the two reinforcing plates 160 are connected to two opposite support plates 110 among the four support plates 110.

[0158] In some embodiments, the two sides of the reinforcing plate 160 abut against two adjacent support plates 110 connected to the support plate 110. That is, the two sides of the reinforcing plate 160 abut against the two sides / adjacent support plates 110 on which the reinforcing plate 160 is connected. This is beneficial to increase the abutment area at the connection of the support plates 110 and improve the strength of the connection, which is advantageous for resistance to deformation. Compared with the reinforcing plate 110 being connected to the side of the support plate 110 away from the elongated cavity 120, by setting the reinforcing plate 110 in the elongated cavity 120 and connecting it to the side of the support plate 110 close to the elongated cavity 120, not only can the thickness of the entire matrix assembly 100 be increased, but also the strength and abutment area of ​​the connection can be increased.

[0159] In some embodiments, the edges on both sides of the reinforcing plate 160 abut against two adjacent and corresponding support plates 160 of the support plate 110 to which the reinforcing plate 160 is connected.

[0160] In some embodiments, the reinforcing plate 160 also has a fourth sub-hole 184 corresponding to the through hole 180 on the support plate 110, which may correspond to the second sub-hole 182 on the second plate 150.

[0161] In some embodiments, the fourth sub-hole 184 may also serve as a positioning hole so that when it is mounted on the support plate 110, it can be positioned and installed with the through hole 110 or the second sub-hole 182 on the second plate 150.

[0162] In some embodiments, the reinforcing plate 160 is disposed on the second plate 150 in the direction toward the elongated cavity 120, that is, in the direction away from the first plate 140.

[0163] In some embodiments, the reinforcing plate 160 is attached to the second plate 150. In some embodiments, the reinforcing plate 160 is connected to the second plate 150. In some embodiments, the reinforcing plate 160 is bonded to the second plate 150. In some embodiments, the reinforcing plate 160 has a similar shape to the support plate 110, thereby increasing the contact area and improving the stability of the entire structure when the reinforcing plate 160 is attached to the support plate 110.

[0164] In some embodiments, the reinforcing plate 160 may be a single plate, which may be disposed on a second plate 150.

[0165] In some embodiments, when there is only one reinforcing plate 160, it can be integrally formed with the second plate 150. Specifically, the reinforcing plate 160 and the second plate 150 can be integrally formed by folding the plate substrate 300.

[0166] In some embodiments, the number of folded plates 310 of the plate substrate 300 forming the second plate 150 is greater than the number of second plates 150. For example, if there are four second plates 150 forming a rectangular enclosing structure, the number of folded plates 310 can be five or six.

[0167] like Figure 16 As shown, the plate substrate 300 includes five folding plates 310 in sequence along the folding direction. After the five folding plates 310 are folded four times in sequence, the last folding plate 310 and the first folding plate 310 are attached to each other. Among the two folding plates 310 that are attached to each other, the one that is relatively closer to the long cavity 120 serves as a reinforcing plate 160, and the one that is relatively farther away from the long cavity 120 serves as a second plate 150. The other three folding plates 310 serve as the second plate 150 independently.

[0168] In some embodiments, there may be two reinforcing plates 160, which may be respectively connected to two opposing second plates 150.

[0169] In some embodiments, one of the two reinforcing plates 160 may be integrally formed with one of the two second plates 150, and the other may be independently connected to the opposite second plate 150, that is, connected to the other of the two second plates 150. This is not limited here. The integral forming method of the reinforcing plate 160 and the second plate 150 has been described in the above embodiments and will not be repeated here.

[0170] In some embodiments, a separate folding plate 310 can be connected to another second plate 150 opposite to the second plate 150 provided with a reinforcing plate 160, thereby forming a reinforcing plate 160, which can be connected to the second plate 150 by means of adhesive, snap-fit ​​or other means.

[0171] In the above embodiments, by providing more folded plates 310 than the required second plate 150 on the substrate 300, the last folded plate 310 can be attached to the first folded plate 310 after folding. This facilitates the connection between the last folded plate 310 and the first folded plate 310, whether by adhesive or other methods, ensuring a more stable structure for the second plate 150 after folding. Furthermore, by forming at least one folded plate 310 as a reinforcing plate 160, the strength of the entire support assembly 100 is improved. Moreover, by also providing a reinforcing plate 160 on the opposite second plate 150, the strength of the entire support assembly 100 is further enhanced. The opposing arrangement of the two reinforcing plates 160 allows the entire support assembly 100 to maintain higher stability under stress, ensuring structural symmetry.

[0172] In some embodiments, such as Figure 18 As shown, the reinforcing plate 160 has a clearance window 132 for exposing the substrate sheet 210, that is, the clearance window 132 that exposes the substrate sheet 210 into the elongated cavity 120, that is, the clearance window 132 that connects the substrate sheet 210 and the elongated cavity 120. In some embodiments, the clearance window 132 may connect the exposure window 131 and the elongated cavity 120.

[0173] In some embodiments, the orthographic projection of the exposure window 131 onto the main surface of the substrate sheet 210 lies within the orthographic projection of the avoidance window 132 onto the main surface of the substrate sheet 210. This prevents the avoidance window 132 from obstructing the exposure window 131 and affecting the passage of aerosols. In some embodiments, the support assembly 100 includes a plurality of support plates 110, with adjacent pairs of the plurality of support plates 110 connected to each other. In some embodiments, adjacent pairs of the plurality of support plates 110 are nested together to achieve connection. In some embodiments, the plurality of support plates 110 are sequentially arranged end-to-end to form an airflow channel. In some embodiments, an airflow channel is formed within the elongated cavity 120.

[0174] In some embodiments, the elongated cavity 120 itself is an airflow channel, which is cavity-shaped and can be used for airflow passage. In some embodiments, in the circumferential direction of the airflow channel, both sides of the support plate 110 are provided with connecting portions 190, and any two adjacent support plates 110 are connected by corresponding connecting portions 190.

[0175] In some embodiments, any two adjacent support plates 110 are nested together by a connecting portion 190.

[0176] In some embodiments, such as Figure 22 Each of the multiple support plates 110 has connecting portions 190 on both sides, and each support plate 110 can be connected to the connecting portions 190 of adjacent support plates 110 through the connecting portions 190 on both sides. Adjacent support plates 110 can be nested together through the connecting portions 190.

[0177] In some embodiments, the connecting portion 190 includes a locking tooth 191 and a locking groove 192 disposed on the support plate 110. Optionally, the locking tooth 191 and the locking groove 192 are continuously staggered on both sides of the support plate 110 in the length direction.

[0178] In some embodiments, the locking teeth 191 of the connecting portion 190 of one of the two adjacent support plates 110 engage with the locking grooves 192 of the connecting portion 190 of the other support plate 110. The engagement of the locking teeth 191 and the locking grooves 192 enhances the connectivity between the support plates 110, thereby strengthening the integrity and strength of the entire support assembly 100. Furthermore, when the support assembly 100 is compressed, especially when it consists of four support plates 110, it may bend under pressure and form a non-rectangular parallelogram. By providing locking grooves 192 and locking teeth 191 at the corners, a certain amount of force can be borne, preventing the support assembly 100 from bending, thus effectively improving the stability of the entire aerosol product.

[0179] In some embodiments, when the locking teeth 191 of one of two adjacent support plates 110 engage with the locking groove 192 of the other, the locking teeth 191 facing away from the surface of the support plate 110 (i.e. the surface facing away from the connecting portion on the other side of the support plate 110) are flush with the outer surface of the adjacent support plate 110, so that the entire support assembly 100 has a smooth / flat columnar structure and maintains the smoothness of its corners.

[0180] In some embodiments, a slot 192 is formed between adjacent teeth 191.

[0181] In some embodiments, there are four support plates 110, and the connecting portions 190 in two opposite support plates 110 have the same structure.

[0182] In some embodiments, the connecting portion 190 can be formed by slotting along the length direction on both sides of the support plate 110, with the hollowed-out portion forming a slot 192 and the other portion forming a tooth 191.

[0183] In some embodiments, each support plate 110 includes a first plate body 140, that is, the support assembly 100 includes at least three first plate bodies 140.

[0184] In some embodiments, the first plate 140 can be connected to the corresponding second plate 150 by means of adhesive, snap-fit, or other methods.

[0185] In some embodiments, such as Figure 24 The locking tooth 191 includes a first sub-tooth 193 disposed on the first plate 140, and the locking groove 192 includes a first sub-groove 194 disposed on the first plate 140.

[0186] Optionally, on both sides of the first plate 140, the first sub-tooth 193 and the first sub-groove 194 are arranged in a continuous staggered manner.

[0187] In some embodiments, at least three first plates 140 are nested together to form a first plate sleeve 145, which can be fitted onto the enclosing structure formed by at least three second plates 150, and can maintain relative stability with the second plates 150 through a certain abutment / friction.

[0188] In some embodiments, a first sub-groove 194 is formed between adjacent first sub-teeth 193.

[0189] In some embodiments, the connecting portion 190 can be formed by slotting along the length direction on both sides of the first plate 140, with the hollowed-out portion forming a first sub-groove 194 and the other portion forming a first sub-tooth 193.

[0190] In some embodiments, the support plate 110 further includes a third plate 170, which can be connected to the first plate 140 by means of fitting or snapping.

[0191] In some embodiments, the third plate 170 is disposed on the side of the first plate 140 opposite to the elongated cavity 120.

[0192] In some embodiments, the third plate 170 is disposed on the side of the first plate 140 opposite to the elongated cavity 120.

[0193] In some embodiments, such as Figure 23 The locking tooth 191 also includes a second sub-tooth 195 disposed on the third plate 170, and the locking groove 192 includes a second sub-groove 196 disposed on the third plate 170. Optionally, the second sub-tooth 195 and the second sub-groove 196 are continuously staggered on both sides of the third plate 170 in the length direction.

[0194] In some embodiments, a second sub-groove 196 is formed between adjacent second sub-teeth 195.

[0195] In some embodiments, the connecting portion 190 can be formed by slotting along the length direction on both sides of the third plate 170, with the hollowed-out portion forming a second sub-groove 196 and the other portion forming a second sub-tooth 195.

[0196] In some embodiments, at least three third plates 170 are nested together to form a second plate sleeve 175, which can be fitted onto the first plate sleeve 145 and can maintain relative stability with the first plate 140 through a certain abutment / friction.

[0197] In some embodiments, the first sub-tooth 193 and the second sub-tooth 195 have the same structure, and the first sub-groove 194 and the second sub-groove 196 have the same structure.

[0198] In some embodiments, the first sub-tooth 193 can engage with the first sub-slot 194 and the second sub-slot 196 simultaneously, and the second sub-tooth 195 can also engage with the first sub-slot 194 and the second sub-slot 196 simultaneously.

[0199] In the above embodiments, by providing connecting portions 190 on both sides of the support plate 110 of the support assembly 100, adjacent support plates 110 can be connected through the connecting portions 190, thereby strengthening the connection stability between the support plates 110, thereby strengthening the strength of the entire support assembly 100 and improving the stability of the entire aerosol product.

[0200] In some embodiments, the support plate 110 includes a third plate 170 disposed on the side of the first plate 140 opposite to the elongated cavity 120.

[0201] In some embodiments, the third plate 170 is connected to the first plate 140 by means of adhesive, snap-fit, or other methods.

[0202] In some embodiments, a plurality of third plates 170 form a second plate sleeve 175, which can be fitted onto a first plate sleeve 145 formed by at least three first plates 140, and can maintain relative stability with the second plate 150 by a certain abutment / friction with the second plate 150.

[0203] In some embodiments, the aerosol generating article 10 further includes a wrapping layer 600, which can be fitted onto a plurality of support plates 110.

[0204] In some embodiments, the wrapping layer 600 may be wrapped around the periphery of a tubular structure formed by connecting multiple support plates 110 end to end.

[0205] In some embodiments, the substrate sheet 210 includes a main surface facing the elongated cavity 120 away from the back surface of the elongated cavity 120.

[0206] In some embodiments, the support plate 110 has an air passage R2 connecting the back side of the matrix sheet 210 and the elongated cavity 120. Optionally, when the matrix sheet 210 is heated, a portion of its aerosol will overflow from the main surface, while a portion can enter the elongated cavity 120 through the air passage R2, thereby effectively reducing aerosol waste.

[0207] In some embodiments, the airway R2 includes an air outlet window 171, an air outlet channel 172, and a through hole 180.

[0208] In some embodiments, the ventilation window 171 is used to expose or connect to the back side of the substrate sheet 210.

[0209] In some embodiments, the air passage 170 and the through hole 180 are used to connect the air window 171 and the elongated cavity 120.

[0210] In some embodiments, the third plate 170 has an air vent 171 disposed on the side of the matrix sheet 210 away from the elongated cavity 120, that is, it has an air vent 171 opposite to the back side of the matrix sheet 210.

[0211] In some embodiments, such as Figure 19 As shown, the third plate 170 also has an air passage 172 that connects to the air passage window 171, and the air passage 171 is arranged along the length direction of the third plate 170.

[0212] In some embodiments, the first plate 140 and the third plate 170 together define an air vent 171 and an air vent 172.

[0213] In some embodiments, the first plate 140, the third plate 170, and the wrapping layer 600 together define an air vent 171 and an air vent 172, which is not limited here.

[0214] In some embodiments, the wrapping layer 600 covers at least a portion of the ventilation window 171 and at least a portion of the ventilation channel 172.

[0215] In some embodiments, such as Figure 19 As shown, the support plate 110 is also provided with a through hole 180, which connects the air passage 172 and the long cavity 120.

[0216] In some embodiments, the through hole 180 is a through hole that penetrates the first plate 140 and the third plate 170.

[0217] In some embodiments, the through hole 180 is a through hole that penetrates the first plate 140, the second plate 150 and the third plate 170.

[0218] In a specific scenario, when the substrate 210 is heated, it generates aerosols. A portion of these aerosols overflows into the elongated cavity 120 from the side facing the elongated cavity 120 (i.e., the side facing the main surface), specifically through the exposure window 131. However, aerosols are also generated on the side facing away from the elongated cavity 120 (i.e., the side closer to the third plate 170, i.e., the back side). Due to the obstruction of the substrate 210 itself, these aerosols may not overflow. Therefore, by positioning the third plate 170 on the side of the substrate 210 facing away from the elongated cavity... A ventilation window 171 is provided on one side of the 120, and a ventilation channel 172 is provided on the third plate 170 to connect the ventilation window 171. A through hole 180 is provided on the support plate 110 to connect the ventilation channel 172 and the long cavity 120. This allows aerosols to enter the long cavity 120 in sequence through the ventilation window 171, the ventilation channel 172 and the through hole 180, thereby mixing with the aerosols in the long cavity 120, increasing the concentration of aerosols and reducing aerosol waste.

[0219] In some embodiments, the through hole 180 is located between the matrix sheet 210 and the proximal end 121, so that the aerosol overflowing from the through hole 180 has a shorter travel distance to the proximal end 121.

[0220] In some embodiments, the through hole 180 includes a first sub-hole 181 that penetrates the first plate 140.

[0221] In some embodiments, the through hole 180 includes a second sub-hole 182 that penetrates the second plate 150.

[0222] In some embodiments, the through hole 180 includes a third sub-hole 183 that penetrates the third plate 170.

[0223] In some embodiments, the first sub-hole 181, the second sub-hole 182, and the third sub-hole 183 may be pre-set and may serve as positioning holes to facilitate positioning when at least two of the first plate 140, the second plate 150, and the third plate 170 are assembled and connected, so that at least two of the first plate 140, the second plate 150, and the third plate 170 can be aligned.

[0224] In some embodiments, through holes may also be provided on the first plate 140, the second plate 150 and the third plate 170, and the through holes may serve as independent positioning holes so that at least two of the first plate 140, the second plate 150 and the third plate 170 can be aligned during installation.

[0225] In some embodiments, the first plate 140 has multiple substrate sheets 210, and the multiple substrate sheets 210 are spaced apart along the length direction of the first plate 140, and the corresponding ventilation windows 171 are also arranged in multiple ways along the length direction of the third plate 170.

[0226] In some embodiments, the ventilation channel 172 may be connected in sequence to a plurality of ventilation windows 171.

[0227] In some embodiments, the ventilation channel 172 at least partially overlaps with the ventilation window 171.

[0228] In some embodiments, the air passage 172 is at least partially disposed opposite to the substrate sheet 210.

[0229] In some embodiments, the ventilation window 171 and the exposure window 131 correspond to each other and can both be octagonal, circular, or other shapes.

[0230] In some embodiments, the orthographic projection of the ventilation window 171 onto the main surface of the substrate 210 at least partially coincides with the orthographic projection of the exposure window 131 onto the main surface of the substrate 210.

[0231] In some embodiments, the orthographic projection of the ventilation window 171 onto the main surface of the substrate 210 coincides with the orthographic projection of the exposure window 131 onto the main surface of the substrate 210.

[0232] In some embodiments, the third plate 170 covers at least a portion of the substrate sheet 210 to limit the movable travel of the substrate sheet 210.

[0233] In some embodiments, the third plate 170 abuts against at least a portion of the substrate sheet 210 to limit the displacement of the substrate sheet 210, so that the substrate sheet 210 can be stably positioned in the receiving cavity 141.

[0234] In some embodiments, the third plate 170 of the plurality of support plates 110 is integrally formed, that is, all the third plate 170 in the support assembly 100 is integrally formed. The formation method is similar to the integral forming method of the second plate 150 described above. It can also be formed by folding the plurality of folding plates 310 in the plate substrate 300, which will not be described in detail here.

[0235] In the above embodiments, by providing a third plate 170 on the side of the first plate 140 away from the long cavity 120, and providing an air vent 171 opposite to the matrix sheet 210 and an air vent 172 communicating with the air vent 171 on the third plate 170, and providing a through hole 180 communicating with the air vent 172 and the long cavity 120 on the support plate 110, the aerosol overflowing from the back of the matrix sheet 210 can enter the long cavity 120 through the air vent 171, the air vent 172 and the through hole 180, and mix with the aerosol entering the long cavity 120 from the main surface of the matrix sheet 210, the concentration of aerosol can be effectively increased and the loss of aerosol can be reduced.

[0236] In some embodiments, the first plate 140 and the second plate 150 may be a single piece.

[0237] In some embodiments, the first plate 140 and the third plate 170 may be a single piece.

[0238] In some embodiments, the first plate 140, the second plate 150, and the third plate 170 are integral parts, which is not limited here.

[0239] In some embodiments, the second plate 150 is located on the side of the first plate 140 facing the elongated cavity 120, and the third plate 170 is located on the side of the second plate 150 away from the elongated cavity 120.

[0240] In some embodiments, such as Figure 5 and Figure 11 The aerosol generating product 10 also includes a nozzle 400.

[0241] In some embodiments, the suction nozzle 400 is connected to the support assembly 100 and is at least partially disposed opposite to the elongated cavity 120, so that the aerosol in the elongated cavity 120 can be drawn through the suction nozzle 400, and the suction nozzle 400 protrudes from the support assembly 100 so that the user can draw in aerosol more effectively.

[0242] In some embodiments, the nozzle 400 is connected to the proximal end of the elongated cavity 120 and protrudes from the support assembly 100.

[0243] In some embodiments, the mouthpiece 400 includes an adapter 410 for connection to the support assembly 100 and a sucking portion 420 connected to the adapter 410.

[0244] In some embodiments, the suction portion 420 protrudes from the support assembly 100. In some embodiments, the adapter portion 410 is at least partially received in the elongated cavity 120. In some embodiments, the suction portion 420 protrudes from the elongated cavity 120. In some embodiments, the adapter portion 410 is at least partially received in the proximal end 121 of the elongated cavity 120. In some embodiments, the cross-section of the adapter portion 410 is adapted to the cross-section of the elongated cavity 120 such that when the adapter portion 410 is inserted into the elongated cavity 120, its adapter portion 410 abuts against a plurality of support plates 110 to prevent aerosol from escaping from the gap between the adapter portion 410 and the support plates 110.

[0245] In some embodiments, at least a portion of the substrate sheet 210 is exposed within the elongated cavity 120, such that when the substrate sheet 210 is heated to generate an aerosol, it can overflow into the elongated cavity 120.

[0246] In some embodiments, the adapter 410 is sealed to the support assembly 100 to prevent its aerosol from leaking out from the gap between the adapter 410 and the support assembly 100.

[0247] In some embodiments, the outer contour of the adapter 410 is adapted to the cross-section of the elongated cavity 120.

[0248] In some embodiments, the outer surface of the suction portion 420 is a cylindrical surface.

[0249] In some embodiments, the outer contour of the cross-section of the support component 100 is a polygon, so that the outer surface of the suction part 420 is a cylindrical surface, which is better suited to the user's suction habits than the outer contour of the support component 100 being a polygon.

[0250] In some embodiments, the adapter 410 is offset from the substrate sheet 210 along the length of the elongated cavity 120. In some embodiments, the main surface of the substrate sheet 210 is at least partially exposed to the exposure window 131. In some embodiments, the adapter 410 and the elongated cavity 120 are interference-fitted. In some embodiments, the elongated cavity 120 is a cylinder with a rectangular cross-section, and the adapter 410 can be an adapted cylinder with a rectangular cross-section, so that it can be embedded in and fixed within the elongated cavity 120. In some embodiments, the elongated cavity 120 is a cylinder with a triangular cross-section, and the adapter 410 can be an adapted cylinder with a triangular cross-section, so that it can be embedded in and fixed within the elongated cavity 120.

[0251] In some embodiments, the nozzle 400 is misaligned with the matrix sheet 210 on the support plate 110 to avoid interfering with the overflow of aerosol. Specifically, the adapter 410 and the matrix sheet 210 may be misaligned.

[0252] In some embodiments, the adapter 410 may wrap around at least a portion of the end of the support assembly 100, i.e., the adapter 410 has a sleeve structure that can be sleeved on at least a portion of the end of the support assembly 100, so that it can be connected to the support assembly 100 and close the elongated cavity 120.

[0253] In some embodiments, the adapter 410 is formed with a sleeve groove 411, which can be sleeved onto the end of the support assembly 100 through the sleeve groove 411.

[0254] In some embodiments, the mouthpiece 400 is provided with a filter section made of cellulose acetate, synthetic fiber, etc., thus giving the mouthpiece 400 a certain filtering function. In some embodiments, the sucking part 420 is provided with a filter section. In some embodiments, the adapter part 410 is provided with a filter section. In some embodiments, the mouthpiece 400 as a whole is a filter section. In some embodiments, the mouthpiece 400 is provided with a sucking channel (not shown) communicating with the elongated cavity 120. Optionally, the sucking channel runs through the entire mouthpiece 400 and communicates with the elongated cavity 120.

[0255] In some embodiments, the inhalation portion 420 is cylindrical, which better mimics the filter of a cigarette to conform to the user's usage habits and improve the user experience.

[0256] In the above embodiments, by including an adapter 410 and a suction part 420 in the nozzle 400, the adapter 410 can be adapted to the shape of the support component 100 and thus communicate with the support component 100, while the suction part 420 is cylindrical, so that the entire nozzle 400 can function as a transfer device. Compared with directly sucking the long cavity 120 with a cross-section of triangle or polygon, the cylindrical suction part 420 is more suitable for the user's sucking habits, allowing the user to better suck the aerosol generating product 10 and improve the user experience.

[0257] In some embodiments, such as Figure 8 As shown, the aerosol generating article 10 also includes a plug 500, which is disposed at the end of the support assembly 100 away from the nozzle 400.

[0258] In some embodiments, the plug 500 may be embedded in the elongated cavity 120, and may also be adapted to the elongated cavity 120 in a similar manner to the adapter 410, so as to prevent aerosol from overflowing from the end of the elongated cavity 120 away from the nozzle 400.

[0259] In some embodiments, the plug 500 is inserted into the distal end 122 of the elongated cavity 120.

[0260] In some embodiments, the plug 500 may also be sleeved on the end of the support assembly 100 away from the nozzle 400 to close the opening of the elongated cavity 120 away from the nozzle 400.

[0261] In some embodiments, the aerosol generating article 10 further includes an encapsulation layer 600, which can be fitted onto the support component 100.

[0262] In some embodiments, the wrapping layer 600 may be made of paper or the like. In some embodiments, the thickness of the wrapping layer 600 is less than the thickness of the support plate 110. In some embodiments, the wrapping layer 600 is fitted onto a second plate sleeve 175 surrounded by at least three third plate bodies 170.

[0263] In some embodiments, the ventilation window 171 and ventilation channel 170 on the third plate 170 can be blind slots, with the slot opening on the side facing the first plate 140 blocked by the first plate 140 / matrix sheet 210, thereby forming a channel structure with the ventilation window 171 and ventilation channel 170.

[0264] In some embodiments, the ventilation window 171 and ventilation channel 170 on the third plate 170 can be a slotted structure, with the slot on the side facing the first plate 140 blocked by the first plate 140 / matrix sheet 210, and the slot on the side away from the first plate 140 blocked by the wrapping layer, thereby making the ventilation window 171 and ventilation channel 170 form a channel structure.

[0268] like Figure 2 Regarding the aerosol generating article 10 shown, its plurality of third plates 170 can be integrally formed, and the enclosing structure formed by the plurality of third plates 170 is the skeleton of the entire aerosol generating article 10.

[0269] A substrate 300 is provided, comprising five folded plates 310, with folding grooves 320 between the five folded plates 310.

[0270] This application also provides an aerosol generation system 30, which includes the aerosol generation article 10 provided in any of the above embodiments, and also includes an aerosol generation device 20.

[0271] In some embodiments, the aerosol generating apparatus 20 includes a heating chamber 21, which can be adapted to the aerosol generating article 10.

[0272] In some embodiments, the aerosol generating article 10 is removably inserted into the heating chamber 21, and the aerosol generating device 20 further includes a heating component 22, which can heat the matrix sheet 210 in the aerosol generating article 10.

[0273] In some embodiments, the heating assembly 22 may include a plurality of resistive elements (not shown) that can heat the substrate 210 by contacting it.

[0274] In some embodiments, the heating component 22 forms a heatable area in the heating chamber, and when the aerosol generating article 10 is removably inserted into the heating chamber 21, the matrix sheet 210 of the matrix component 200 is located in the heatable area.

[0275] In some embodiments, the nozzle 400 is offset from the heatable area to prevent the nozzle 400 from being heated by the heating component 22 and producing a burnt taste.

[0276] In some embodiments, the heating assembly 22 may include a plurality of magnetic induction coils 23, each of which generates a variable magnetic field to heat the corresponding substrate sheet 210. Specifically, the variable magnetic field can heat the receptor layer 212 of the substrate sheet 210, so that the receptor layer 212 can heat the aerosol matrix layer 211, thereby generating the aerosol-generated article 10.

[0277] In some embodiments, the heating cavity 21 is a rectangular body, specifically a rectangular body with a square cross-section.

[0278] In some embodiments, the magnetic induction coil 23 may specifically be a planar coil.

[0279] In some embodiments, the magnetic induction coil 23 can be a planar coil with a shape adapted to the substrate sheet 210. For example, if the substrate sheet 210 is circular, the magnetic induction coil 23 can also be circular; if the substrate sheet 210 is rectangular, the magnetic induction coil can also be square.

[0280] In some embodiments, the magnetic induction coil 23 may be disposed on two opposite sides of the heating chamber 21, which can heat the aerosol generation article 10 having a matrix sheet 210 on the two support plates 110.

[0281] In some embodiments, magnetic induction coils 23 may be disposed on the four sides of the heating chamber 21, which can heat the aerosol generation articles 10 having matrix sheets 210 on the four support plates 110.

[0282] In some embodiments, the magnetic induction coil 23 may not be directly connected to the heating cavity 21, that is, it may be hidden in the side wall around the heating cavity 21.

[0283] In some embodiments, when the aerosol generating article 10 is removably inserted into the heating chamber 21, its matrix sheet 210 corresponds one-to-one with the magnetic induction coil, specifically they can be arranged relative to each other, and the magnetic induction coil can generate a changing magnetic field to heat the corresponding matrix sheet 210.

[0284] In some embodiments, the magnetic induction coils 23 can be controlled independently to heat the corresponding substrate sheets 210 in sequence.

[0285] In specific scenarios, the use of the aforementioned aerosol generating product 10 and aerosol generating system 30 will be described, such as... Figure 6 and Figure 25 As shown, the heating component 22 in the aerosol generating device 20 heats the matrix component 200 in the aerosol generating product 10. Specifically, its magnetic induction coil 23 can heat the matrix sheet 210 in sequence, thereby heating the matrix sheet 210 sequentially and generating aerosol.

[0286] A portion of the aerosol overflows directly from the main surface of the matrix sheet 210 and enters the long cavity 120 through the exposure window 131. The aerosols formed by the multiple matrix sheets 210 can all be collected in the long cavity 120. When the user performs suction, the aerosol passes through the nozzle 400 along the main airway R1. On the other hand, the aerosol overflows from the back of the matrix sheet 210 and enters the long cavity 120 through the airway R2 formed by the airway window 171, the airway channel 172, and the through hole 180, and merges with the main aerosol R1, thereby ensuring the full utilization of the aerosol.

[0287] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification.
