Description

Technical Field

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

[0002] This section is intended to provide background or context for embodiments of this application. The description herein is not intended to imply that it is prior art simply because it is included in this section.

[0003] Aerosol-generating products include a matrix segment, which can generate aerosols by ignition or by heating without combustion.

[0004] In related technologies, the matrix segment has a large suction resistance, which leads to excessive suction resistance in the aerosol-generated products and affects the suction experience. Utility Model Content

[0005] In view of this, embodiments of this application aim to provide a matrix strip, a matrix segment, and an aerosol-generating article, wherein the matrix strip is used to fill the matrix segment, thereby reducing suction resistance.

[0006] This application provides a matrix strip for generating aerosols. The length of the matrix strip is greater than the hydraulic diameter of its cross-section. The cross-section of the matrix strip is perpendicular to its length direction. At least one portion of the matrix strip is bent.

[0007] In some embodiments, the matrix strip is an extruded structure.

[0008] In some embodiments, at least a portion of the matrix strip is periodically bent toward opposite sides.

[0009] In some embodiments, the matrix strip includes at least one first arc segment and at least one second arc segment, both of which are arc-shaped, and the first and second arc segments have opposite bending directions, and are alternately arranged along the length direction.

[0010] In some embodiments, the matrix strip comprises a plurality of straight segments connected sequentially along its length, and the included angle between two adjacent straight segments is an acute angle.

[0011] In some embodiments, the matrix strip is curved in a spatial spiral shape.

[0012] In some embodiments, the matrix strip is folded around at least one side along its length.

[0013] In some embodiments, the cross-section of the matrix strip is rectangular.

[0014] In some embodiments, the width of the rectangular cross-section of the matrix strip is 0.60 mm to 1.50 mm; and / or,

[0015] The thickness of the rectangular cross-section of the substrate strip is 0.10mm-0.30mm.

[0016] In some embodiments, the length of the substrate strip is 5.0 mm to 15.0 mm.

[0017] In some embodiments, the matrix strip comprises homogeneous tobacco material.

[0018] This application provides a matrix segment, including:

[0019] Multiple matrix strips as described in any of the above.

[0020] In some embodiments, the filling rate of the matrix segment is 2 cm³ / g-6 cm³ / g.

[0021] In some embodiments, the matrix segment is formed by filling the matrix strip; or,

[0022] The matrix segment also includes at least one of sheet matrix, filamentary matrix and granular matrix.

[0023] This application provides an aerosol generating article, comprising a matrix segment and at least one functional segment as described in any of the above claims, wherein the matrix segment and the functional segment are disposed along a first direction.

[0024] Compared to straight substrates, the substrate strips provided in this application are curved strip structures with at least one curved part. The contact area between each substrate strip is small, making them less prone to sticking together, which can improve the filling rate and reduce the suction resistance. Thus, while meeting the suction resistance requirements, it can also improve the utilization rate of raw materials and reduce production costs. Because each substrate strip has good dispersibility, it is easy to mix the substrate strip with shredded tobacco leaves evenly, which can improve the problem of uneven taste. It can also provide a good material basis for mixing and blending with other types of substrates, rolling and other processes, which is very beneficial for efficient application in aerosol-generated products.

[0043] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0044] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features / embodiments can form different implementation methods. To avoid unnecessary repetition, the various possible combinations of various specific technical features / embodiments in this application will not be described separately. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] It should be noted that in this application, "multiple" refers to a quantity including two or more.

[0046] In this application, the unit "mm" refers to millimeters. The unit "cm" refers to centimeters. 3 / g means cubic centimeters per gram. The unit "m / min" means meters per minute.

[0047] In the relevant technology, the applicant found that the matrix segment includes multiple matrix filaments that extend in a straight line. In other words, the matrix filaments are roughly straight in shape. The contact area between these straight matrix filaments is large, making them prone to adhesion. The matrix segment with a straight matrix has a low filling rate. The same volume requires more weight of straight matrix. Too much weight of straight matrix will make the matrix segment too dense, resulting in increased suction resistance and a poorer user experience.

[0048] The applicant also found that if shredded tobacco leaves are used to completely fill the matrix segment, the shape and size of the tobacco leaves are extremely important, as the stems and broken leaves in the tobacco raw material cannot be used to make the matrix segment, resulting in serious waste of raw materials. However, other reconstituted tobacco products made using papermaking, slurry processing, and rolling processes require separate processing of tobacco leaves and stems, often resulting in low utilization rates. Moreover, the smoking effect, such as draw resistance, differs from that of shredded tobacco. Whether it is whole-leaf tobacco like shredded tobacco leaves or reconstituted tobacco made using papermaking, slurry processing, and rolling processes, tobacco leaves and stems need to be processed separately, often resulting in low utilization rates. To improve the utilization rate of stems and broken leaves, tobacco leaves, stems, and broken leaves can be pulverized, and then the pulverized raw materials can be mixed with liquid additives to form a slurry. The slurry is then extruded to form a linear matrix. Specifically, a screw extruder is used to mesh and extrude the slurry at a certain temperature, and the slurry forms a linear matrix through the die outlet. This type of linear substrate replaces the shredded tobacco leaves, forming substrate segments through filling. However, the substrate segments using the linear substrate have a relatively high density, for example, reaching 1.0 g / cm³-1.5 g / cm³, with a filling rate typically of 1.0 cm³. 3 / g-2.0cm 3 The filling rate of the matrix segment using shredded tobacco is generally around 4 cm³ / g, while the filling rate of the matrix segment using straight matrix is ​​much lower than that of the matrix segment using shredded tobacco. In addition, there are some problems with the matrix segment using straight matrix during the heating and aerosol generation process. For example, the large contact area between the straight matrix segments makes them prone to sticking together. If the straight matrix is ​​mixed with shredded tobacco, the sticking of the straight matrix makes it difficult to mix the straight matrix and the shredded matrix evenly, which can lead to uneven mixing. This can result in uneven taste in the sensory evaluation of the finished cigarette. For another example, the lower filling rate of the matrix segment using straight matrix means that more weight of straight matrix is ​​needed for the same volume. Too much weight of straight matrix will make the matrix segment too dense, resulting in increased draw resistance and a poorer user experience.

[0049] This application provides a matrix strip 110 and a matrix segment 100, which can solve at least one problem in the related art.

[0050] Please see Figures 1 to 9 The matrix segment 100 provided in this application embodiment includes a plurality of matrix strips 110 as described in any one embodiment of this application. The matrix strips 110 are used to generate aerosols, the length dimension of the matrix strips 110 is greater than the hydraulic diameter of the cross section of the matrix strips 110, the cross section of the matrix strips 110 is perpendicular to the length direction of the matrix strips 110, and at least one part of the matrix strips 110 is bent.

[0051] The hydraulic diameter of the cross-section of the substrate strip 110 is the ratio of 4 times the area of ​​the cross-section to the perimeter of the cross-section.

[0052] The length dimension of the substrate strip 110 is greater than the hydraulic diameter of the cross section of the substrate strip 110, and at least one part of the substrate strip 110 is bent. The substrate strip 110 is generally a long or short strip with local bending.

[0053] At least one part of the substrate strip 110 is bent; in other words, the curvature of at least one part of the substrate strip 110 is not zero. For example, it may be a bent part of the substrate strip 110, or it may be a bent part of the substrate strip 110.

[0054] The multiple matrix strips 110 in matrix segment 100 can be arranged randomly or in an ordered manner; please refer to [reference needed]. Figure 13 , Figure 13 Multiple matrix strips 110 are arranged in a disordered manner. Disordered arrangement means randomly generated and difficult to predict. Please refer to [link to relevant documentation]. Figure 14 , Figure 14 Multiple matrix strips 110 are arranged in an orderly manner, and the orderly arrangement means that it is mainly based on the design and processing, and has predictability.

[0055] In some embodiments, the matrix strip 110 is an extruded molding structure. Specifically, the slurry is subjected to a set temperature and a set pressure, and then passes through the discharge port 2000 of the molding die (see [reference]). Figure 11 The extruded matrix strip 110 is formed into a curved strip structure with at least one curved part. The cross-sectional shape of the extruded matrix strip 110 is approximately the same as or slightly different from the shape of the outlet 2000.

[0056] The matrix strip 110 has an extrusion molding structure, which can be formed by pulverizing raw materials such as tobacco raw materials and extruding them. This can reduce the quality requirements of tobacco leaves and also allow tobacco stems and broken leaves to be used to manufacture the matrix segment 100, thereby improving the utilization rate of tobacco raw materials.

[0057] Extrusion, for example, includes a barrel and a screw. A cavity for receiving slurry is formed within the barrel. A forming die is disposed at the port of the barrel, and the screw is disposed within the cavity. The screw extrudes and pushes the slurry within the cavity. The slurry continuously passes through the outlet 2000 of the forming die to form at least partially curved matrix strips 110. Compared to shredded tobacco leaves and reconstituted tobacco prepared by papermaking, slurry processing, and rolling processes, extruded slurry can include granular substrates formed from pulverized tobacco raw materials such as tobacco leaves, stems, and dust. This eliminates the need for sorting tobacco leaves and stems, resulting in relatively lower requirements for tobacco leaves. The slurry can also include other herbal raw materials besides tobacco, fully utilizing herbal raw materials such as tobacco and reducing waste. Furthermore, the extrusion molding process is simple and can reduce production costs.

[0058] The matrix strip 110 is an integral structure, meaning that the matrix strip 110 is a single, indivisible physical whole that can maintain its overall state without the need for external components.

[0059] Two matrix strips 110 may or may not be connected. Multiple matrix strips 110 can be constrained by a wrapping layer or outer layer 120 to maintain the overall state of the matrix segment 100.

[0060] For example, the slurry may be a mixture of particulate substrate and liquid additives.

[0061] The particle size of the particulate substrate can be at the micrometer level.

[0062] The granular substrate includes, but is not limited to, pulverized tobacco leaves, stems, and shredded leaves. That is, unlike shredded tobacco leaves in related technologies, the substrate strip 110 can be reconstituted tobacco. In other embodiments, the granular substrate can also be made from other herbal raw materials, such as rooibos tea.

[0063] The matrix strip 110 is a particle aggregate composed of a particle substrate.

[0064] The granular substrate may include granular plant materials. The substrate strip 110 may also include an adhesive component for bonding the granular substrate. The adhesive component bonds the granular substrate together to form the main structure of the substrate strip 110, thus the substrate strip 110 is a granular composite made of the granular substrate.

[0065] The particles in a particle aggregate contain micropores, and multiple micropores interconnect to form microchannels. For example, the cross-sectional area and length of the microchannels are naturally formed by the slurry components, and the expansion of the slurry components can create microchannels. Aerosols can flow through these microchannels.

[0066] It should be noted that the microchannels described in this application are disordered, meaning they are difficult to generate in an orderly manner according to a design; in other words, the microchannels are generated randomly. Microchannels are all pores in a microscopic sense, and their size is determined by the gaps between particles. For example, if the slurry is granular, the cross-sectional area and length of the microchannels are naturally formed through the extrusion process and the slurry composition. The slurry expands after flowing out of the mold's outlet (2000mm), thus forming microchannels.

[0067] In some embodiments, the particulate substrate may be formed from plant-based raw materials through granulation. Plant-based raw materials include, but are not limited to, one or more of tobacco leaves, chopped leaves, tobacco stems, tobacco dust, and aromatic plants. Plant-based raw materials are the core source of aroma, and the endogenous substances in plant-based raw materials can produce physiological satisfaction for users. Endogenous substances, such as alkaloids, enter the human bloodstream and promote the pituitary gland to produce dopamine, thereby obtaining physiological satisfaction.

[0068] Compared to a straight matrix, the matrix strip 110 provided in this application is a curved strip structure with at least one curved part. When multiple matrix strips 110 fill the matrix section 100, the contact area between each matrix strip 110 is small, making it less likely to stick together. This can improve the filling rate and reduce the suction resistance. Thus, while meeting the suction resistance requirements, it can also improve the utilization rate of raw materials and reduce production costs. Since each matrix strip 110 has good dispersibility, it is easy to mix the matrix strip 110 with the shredded tobacco leaves evenly, which can improve the problem of uneven taste. It can also provide a good material basis for mixing and blending with other forms of matrix, rolling and other processes, which is very beneficial for efficient application in aerosol generation products 1000.

[0069] The matrix segment 100 provided in this application embodiment can be used to generate aerosols by ignition, that is, the matrix segment 100 reaches the ignition point and generates aerosols by combustion.

[0070] The matrix segment 100 provided in this application embodiment can also be used to generate aerosols by heating without combustion, that is, the matrix segment 100 is heated below the ignition point and will not burn during the aerosol generation process.

[0071] In this application, the cross-section of the matrix strip 110 is not limited. For example, the cross-section of the matrix strip 110 can be a regular shape or an irregular shape. The regular shape includes, but is not limited to, a circle, an ellipse, or a polygon. The polygon includes, but is not limited to, a triangle, a square, a rectangle, a pentagon, or a hexagon. The irregular shape is any shape other than a regular shape.

[0072] In some embodiments, the matrix strip 110 comprises homogeneous tobacco material. Homogeneous tobacco material is a reconstituted tobacco product with approximately uniform mass, made by physically recombining natural tobacco raw materials such as tobacco leaves, stems, and dust with liquid raw materials.

[0073] In some embodiments, the matrix strip 110 further includes a fragrance component, a skeleton component, and a smoke-generating agent component.

[0074] The skeleton component provides a supporting skeleton for the prepared matrix strip 110, which is beneficial to the shaping of the matrix strip 110. In addition, it can also provide support for other components, such as providing support points for the attachment of fragrance components, thereby improving the aroma quality of the matrix segment 100.

[0075] The smoke-generating agent components are easily atomized to produce a large amount of aerosol, thereby increasing the amount of aerosol.

[0076] The fragrance component provides characteristic aromas to the matrix segment 100, thereby enhancing the user's vaping experience.

[0077] The adhesive component comes into close contact with the material interfaces of each component in the matrix strip 110 by wetting, generating intermolecular attraction, thereby playing the role of bonding the powder, liquid and other components.

[0078] In some embodiments, please refer to Figures 1 to 9 The cross-section of the matrix strip 110 is rectangular. Thus, the thickness of the matrix strip 110 is much smaller than its length, and the matrix strip 110 is roughly a flat and curved strip structure.

[0079] In some embodiments, please refer to Figure 2 The width L1 of the rectangular cross-section of the matrix strip 110 is 0.60mm-1.50mm.

[0080] The width L1 of the rectangular cross-section of the matrix strip 110 is the dimension of the long side of the rectangle.

[0081] For example, the width L1 of the rectangular cross-section of the substrate strip 110 can be 0.60mm, 0.65mm, 0.70mm, 0.80mm, 0.90mm, 1.00mm, 1.10mm, 1.20mm, 1.30mm, 1.40mm or 1.50mm, etc.

[0082] In this embodiment, the width of the cross-section of the matrix strip 110 is basically close to the size of the shredded tobacco leaves in the related technology, which is conducive to the matrix strip 110 achieving the smoking effect of the shredded tobacco leaves in the related technology.

[0083] In some embodiments, please refer to Figure 2 The thickness L2 of the rectangular cross-section of the matrix strip 110 is 0.10mm-0.30mm.

[0084] The thickness L2 of the rectangular cross-section of the matrix strip 110 is the dimension of the short side of the rectangle.

[0085] For example, the thickness L2 of the rectangular cross-section of the substrate strip 110 can be 0.10 mm, 0.15 mm, 0.20 mm, 0.25 mm, or 0.30 mm, etc.

[0086] In this embodiment, the thickness of the cross-section of the matrix strip 110 is basically close to the size of the shredded tobacco leaves in the related technology, which is conducive to the matrix strip 110 achieving the smoking effect of the shredded tobacco leaves in the related technology.

[0087] In some embodiments, the hydraulic diameter of the cross-section of the substrate strip 110 is approximately 0.2 mm to 0.5 mm.

[0088] For example, the hydraulic diameter of the cross section of the substrate strip 110 can be 0.20 mm, 0.25 mm, 0.30 mm, 0.35 mm, 0.40 mm, 0.45 mm, or 0.50 mm, etc.

[0089] In some embodiments, the length of the substrate strip 110 is 5.0 mm to 15.0 mm.

[0090] For example, the length of the substrate strip 110 is 5.0 mm, 6.0 mm, 7.0 mm, 8.0 mm, 10.0 mm, 11.0 mm, 12.0 mm, 14.0 mm, or 15.0 mm, etc.

[0091] During the extrusion process, the matrix strip 110 extends continuously and can be cut to form a matrix strip 110 of the required length.

[0092] In this embodiment, the matrix strip 110 is of moderate length, suitable for filling to form the matrix segment 100, and also easy to mix with shredded tobacco leaves, which can improve the filling uniformity and meet the filling rate requirements.

[0093] In some embodiments, the matrix strip 110 may be arc-shaped or annular, etc.

[0094] In some embodiments, the filling rate of the matrix segment 100 is 2 cm3 / g-6 cm3 / g.

[0095] The fill rate refers to the volume occupied by a unit mass of matrix segment 100.

[0096] For example, the filling rate of the matrix segment 100 is 2 cm3 / g, 2.5 cm3 / g, 3 cm3 / g, 3.5 cm3 / g, 4 cm3 / g, 5 cm3 / g, or 6 cm3 / g, etc.

[0097] In this embodiment, the lower the filling rate of the matrix segment 100, the greater the true density and mass of the matrix segment 100, the denser the matrix segment 100 is filled, and the greater the draw resistance. Conversely, the higher the filling rate of the matrix segment 100, the smaller the true density and mass of the matrix segment 100, and the smaller the aerosol content. Therefore, the filling rate of the matrix segment 100 is 2cm3 / g-6cm3 / g, which is basically close to the filling rate of the matrix segment 100 composed of shredded tobacco, and has a suitable aerosol content and draw resistance.

[0098] In some embodiments, the matrix segment 100 is filled and shaped by matrix strips 110. The matrix segment 100 includes only matrix strips 110 and no other matrix, such as sheet matrix, filamentary matrix and granular matrix.

[0099] It should be noted that in the embodiment where the matrix segment 100 is filled and formed by matrix strips 110, all matrix strips 110 of the matrix segment 100 are matrix strips 110 of the same shape, or the matrix segment 100 may include matrix strips 110 of various shapes.

[0100] The matrix segment 100 can be formed by filling matrix strips 110 with the same cross-section, that is, the matrix segment 100 can include only matrix strips 110 with one cross-section.

[0101] For example, the matrix segment 100 may be formed by filling the matrix strip 110 with a rectangular cross-section, that is, the matrix segment 100 may only include the matrix strip 110 with a rectangular cross-section.

[0102] The matrix segment 100 can be formed by filling matrix strips 110 with various cross-sections, that is, the matrix segment 100 can include matrix strips 110 with at least two cross-sections.

[0103] For example, the matrix segment 100 can be formed by filling matrix strips 110 with rectangular and hexagonal cross sections, that is, the matrix segment 100 includes matrix strips 110 with both rectangular and hexagonal cross sections.

[0104] The matrix strips 110 can all be of one type. For example, the matrix segment 100 can be filled and shaped by the first matrix strip; or, the matrix segment 100 can be filled and shaped by the second matrix strip; or, the matrix segment 100 can be filled and shaped by the third matrix strip; or, the matrix segment 100 can be filled and shaped by the fourth matrix strip.

[0105] The matrix strip 110 may include matrix strips 110 of various shapes. For example, the matrix segment 100 may be formed by filling two or more of the first matrix strip, the second matrix strip, the third matrix strip and the fourth matrix strip.

[0106] Taking matrix segment 100, which includes multiple matrix strips 110, as an example, the methods of forming matrix segments from multiple monomers include, but are not limited to, the following two:

[0107] One method involves cutting the extruded matrix strip 110 and then rolling it into matrix segments 100 using a rolling machine. The matrix segment 100 is composed of multiple matrix strips 110 arranged in a disordered manner. Another method involves directly winding the extruded matrix strip 110 into matrix segments 100 using a winding machine. The matrix segment 100 is composed of multiple matrix strips 110 arranged in an ordered manner.

[0108] In some embodiments, the matrix segment 100 includes at least one of sheet matrix, filamentary matrix and granular matrix.

[0109] For example, the sheet matrix is ​​formed by processing plant materials such as leaves and tobacco stems into reconstituted sheets, and the processing method includes one of papermaking, slurry processing and roll pressing.

[0110] Please see Figure 16 , Figure 16 The image shows shredded tobacco leaves, which are tobacco leaves cut into shreds. The shredded matrix includes shredded tobacco leaves, which is tobacco leaves and / or the aforementioned sheet matrix cut into shreds.

[0111] Granular matrix is ​​made by crushing tobacco leaves and / or the above-mentioned sheet matrix into dispersed particles with a diameter of millimeters.

[0112] The matrix segment 100 includes at least one of sheet matrix, filament matrix, and granular matrix. The matrix segment 100 may include only sheet matrix and matrix strip 110; or it may include only filament matrix and matrix strip 110; or it may include granular matrix and matrix strip 110; or it may include two or three of sheet matrix, filament matrix, and granular matrix, and include matrix strip 110.

[0113] In this embodiment, at least one of sheet matrix, filament matrix and granular matrix is ​​filled together with matrix strip 110 to form matrix segment 100.

[0114] In some embodiments, please refer to Figures 1 to 3 ,as well as Figure 6 At least a portion of the matrix strip 110 is periodically bent toward opposite sides.

[0115] The periodic bending of at least a portion of the matrix strip 110 toward opposite sides means that at least a portion of the matrix strip 110 exhibits repeated bending undulations toward opposite sides.

[0116] It is possible that a portion of the structure of the matrix strip 110 is periodically bent towards opposite sides, while other portions are not periodically bent towards opposite sides. Alternatively, it is possible that the entire structure of the matrix strip 110 is periodically bent towards opposite sides.

[0117] In some embodiments, please refer to Figures 1 to 3 ,as well as Figure 6 The matrix strip 110 has a rectangular cross-section, and at least a portion of the matrix strip 110 is periodically bent toward the two sides opposite to the width direction of the matrix strip 110.

[0118] In some embodiments, the matrix strip 110 has a rectangular cross-section, and at least a portion of the matrix strip 110 is periodically bent toward two sides opposite to the thickness direction of the matrix strip 110.

[0119] It is understandable that when the cross-section of the substrate strip 110 is rectangular, the width direction of the substrate strip 110 is parallel to the long side of the rectangle, and the thickness direction of the substrate strip 110 is parallel to the short side of the rectangle.

[0120] In this embodiment, at least a portion of the matrix strip 110 is periodically bent toward opposite sides, and multiple matrix strips 110 can form a fluffy mesh-like cross structure. When filling the same volume, less matrix strip 110 is used compared to a straight matrix, and the gap between two matrix strips 110 is larger. The aerosol generated during heating in the suction gap can be temporarily stored in the gap, resulting in a larger amount of aerosol during suction and a better user experience.

[0121] In some embodiments, please refer to Figures 1 to 3 The matrix strip 110 includes at least one first arc segment 111 and at least one second arc segment 112. Both the first arc segment 111 and the second arc segment 112 are arc-shaped. The bending directions of the first arc segment 111 and the second arc segment 112 are opposite. The first arc segment 111 and the second arc segment 112 are alternately arranged along the length direction.

[0122] The first arc segment 111 can be one or more, for example, one, two, three or more.

[0123] The second arc segment 112 can be one or more, for example, one, two, three or more.

[0124] The first arc segment 111 can be circular or elliptical.

[0125] The second arc segment 112 can be circular or elliptical.

[0126] For example, the cross-section of the matrix strip 110 is rectangular, the first arc segment 111 bends toward a first side in the width direction, and the second arc segment 112 bends toward a second side in the width direction, wherein the first side and the second side in the width direction are opposite sides.

[0127] For example, the cross-section of the matrix strip 110 is rectangular, the first arc segment 111 bends toward a first side in the thickness direction, and the second arc segment 112 bends toward a second side in the thickness direction, wherein the first side and the second side in the thickness direction are opposite sides.

[0128] The first arc segment 111 and the second arc segment 112 are alternately arranged along the length direction, which means that the first arc segment 111 and the second arc segment 112 are connected end to end one after another.

[0129] Taking two arc segments 111 and two arc segments 112 as an example, the first arc segment 111, the first arc segment 112, the second arc segment 111, and the second arc segment 112 are connected in sequence.

[0130] Please see Figure 15 , Figure 15 A matrix strip 110, which is roughly sinusoidal in shape, is shown, namely the first matrix strip 110, and the cross-section of the matrix strip 110 is rectangular.

[0131] In this embodiment, the matrix strip 110 is generally shaped like a sinusoidal waveform, with smooth transitions at each part and virtually no sharp corners. This reduces stress concentration, facilitates molding, and lowers the risk of breakage during extrusion. Multiple sinusoidal matrix strips 110 form a loose, cross-linked mesh structure. When filling the same volume, less sinusoidal matrix strip 110 is used compared to a straight matrix. The larger gaps between two sinusoidal matrix strips 110 allow for temporary storage of the aerosol generated during heating in the suction gap, resulting in a larger aerosol volume during suction and a better user experience.

[0132] In some embodiments, the matrix strip 110 includes at least one first arc segment 111 and at least one second arc segment 112. For ease of description, this sine-wave-like matrix strip 110 is referred to as the first matrix strip 110, and the filling rate of the first matrix strip 110 can be 3cm3 / g-5cm3 / g.

[0133] In some embodiments, please refer to Figure 15 The matrix segment 100 can be completely filled by the first matrix strip 110.

[0134] In other embodiments, the matrix segment 100 may include a first matrix strip 110, as well as a particulate matrix, a filamentary matrix, or a sheet matrix, etc.

[0135] For example, please refer to Figure 16 , Figure 16 The diagram schematically illustrates a mixture of the first substrate strip 110 (i.e., the sinusoidal substrate strip 110) and shredded tobacco leaves (i.e., the filamentous substrate).

[0136] In some embodiments, please refer to Figure 6 The matrix strip 110 includes multiple straight segments 113 connected sequentially along the length direction, and the included angle between two adjacent straight segments 113 is an acute angle.

[0137] In this embodiment, the matrix strip 110 is generally composed of periodically connected straight line segments 113 with opposite slopes, forming a continuous sawtooth-shaped broken line, roughly in the form of a triangular wave curve, which can also be referred to as a folded matrix strip 110. Multiple folded matrix strips 110 form a loose, mesh-like cross structure. When filling the same volume, less folded matrix strips 110 are used compared to straight matrix strips. The gaps between two folded matrix strips 110 are larger, and the aerosols generated during heating in the suction gap can be temporarily stored in the gaps, resulting in a larger aerosol volume during suction and a better user experience.

[0138] For ease of description, this folded matrix strip 110 is referred to as the fourth matrix strip 110.

[0139] In some embodiments, the matrix segment 100 may be entirely filled by the fourth matrix strip 110.

[0140] In other embodiments, the matrix segment 100 may include a fourth matrix strip 110, as well as a particulate matrix, a filamentary matrix, or a sheet matrix, etc.

[0141] In other embodiments, the matrix segment 100 may include a fourth matrix strip 110 and a first matrix strip 110.

[0142] In some embodiments, please refer to Figure 4 and Figure 5 The matrix strip 110 is curved in a spatial spiral shape.

[0143] For example, the trajectory formed by the slurry moving in a circle around the first axis while simultaneously moving in a straight line along the first axis is a spatial spiral shape.

[0144] In this embodiment, the matrix strip 110 is curved in a spatial spiral shape, roughly spring-like. All parts of the matrix strip 110 have smooth transitions with virtually no sharp corners, reducing stress concentration, facilitating molding, and lowering the risk of breakage during extrusion. Multiple spring-shaped matrix strips 110 form a loose, interwoven mesh structure. When filling the same volume, less matrix is ​​used compared to a straight matrix strip. The larger gaps between two spring-shaped matrix strips 110 allow for temporary storage of the aerosol generated during heating in the suction gap, resulting in a larger aerosol volume during suction and a better user experience.

[0145] For ease of description, the substrate strip 110, which is curved in a spatial spiral shape, is referred to as the second substrate strip 110. The second substrate strip 110 is roughly in the shape of a spiral spring, and its filling rate can be 3.9 cm. 3 / g to 6cm 3 / g.

[0146] In some embodiments, the matrix segment 100 may be entirely filled by the second matrix strip 110.

[0147] In other embodiments, the matrix segment 100 may also include a second matrix strip 110 and a first matrix strip 110.

[0148] In other embodiments, the matrix segment 100 may also include a second matrix strip 110, a fourth matrix strip 110, and a first matrix strip 110.

[0149] In some embodiments, the matrix segment 100 may include a second matrix strip 110, as well as a particulate matrix, a filamentary matrix, or a sheet matrix, etc.

[0150] In some embodiments, please refer to Figures 7 to 9 The matrix strip 110 is folded and bent 114 around at least one side in the length direction.

[0151] The pleated bend 114 is a bend formed by the stacking of slurry on a surface. For example, during extrusion, if there is relatively more slurry on at least one side of the matrix strip 110, a pleated bend 114 will be formed on that side.

[0152] In some embodiments, the matrix strip 110 is folded 114 around one side in the length direction.

[0153] For example, please refer to Figure 7 Taking the cross-sectional shape of the matrix strip 110 as a rectangle as an example, the matrix strip 110 is bent into a fold shape 114 on one side along the width direction.

[0154] For example, please refer to Figure 9 Taking the cross-sectional shape of the matrix strip 110 as a rectangle as an example, the matrix strip 110 is bent into a fold shape 114 on one side along the thickness direction.

[0155] In some embodiments, the matrix strip 110 is folded 114 around multiple sides in the length direction.

[0156] For example, please refer to Figure 8 Taking the cross-sectional shape of the matrix strip 110 as a rectangle as an example, the two sides of the matrix strip 110 along the width direction are bent in a pleated shape 114.

[0157] For ease of description, a matrix strip 110 with at least one side that is folded and bent 114 is referred to as a third matrix strip 110.

[0158] In some embodiments, the matrix segment 100 may be entirely filled by the third matrix strip 110.

[0159] In other embodiments, the matrix segment 100 may also include at least two of the first matrix strip 110, the second matrix strip 110, the third matrix strip 110, and the fourth matrix strip 110.

[0160] In some other embodiments, the matrix segment 100 may include a third matrix strip 110, as well as a particulate matrix, a filamentary matrix, or a sheet matrix, etc.

[0161] Please see Figure 10 This application provides an aerosol generating article 1000, which includes a matrix segment 100 and at least one functional segment 200 as described in any embodiment of this application. The matrix segment 100 and the functional segment 200 are arranged along a first direction.

[0162] The matrix segment 100 is provided with functional segments 200 at one or both ends along the first direction, and there can be one or more functional segments 200.

[0163] For example, one end of the aerosol generating article 1000 along a first direction faces the user. For ease of description, the two ends of the first direction are defined as the downstream end and the upstream end. The downstream end refers to the end of the aerosol generating article 1000 that is close to the user when the user uses it, and the upstream end refers to the end of the aerosol generating article 1000 that is far from the user when the user uses it. A functional section 200 may be provided at the downstream end of the matrix section 100. During use, the aerosol generated by the matrix section 100 flows through the functional section 200 under suction negative pressure and is then delivered to the user. That is, the functional section 200 is downstream of the matrix section 100 along the first direction, i.e., the downstream end. In some cases, the user can hold the functional section 200 in their mouth to draw in the aerosol generated by the matrix section 100.

[0164] Functional section 200 can provide at least one of the following functions: filtration, adsorption, aroma enhancement, dilution, cooling, and resistance adjustment.

[0165] Filtration function refers to the function of filtering out at least some of the particulate matter in aerosols.

[0166] Adsorption function refers to the ability to adsorb at least some impurities in aerosols. It can be understood that these impurities are substances that remove the active ingredients from the aerosol; the active ingredients are those that need to be provided to the user.

[0167] The aroma-enhancing function refers to the function of adding aroma-producing components to aerosols.

[0168] The dilution function refers to the function of reducing the concentration of active ingredients in aerosols.

[0169] Cooling function refers to the function of reducing the temperature of aerosols.

[0170] The suction resistance adjustment function refers to the function of reducing or increasing suction resistance. In this way, the flow rate and distribution of aerosols can be controlled, and the suction resistance and aerosol uniformity can be optimized.

[0171] In some embodiments, the aerosol-generating article 1000 includes an encapsulation layer wound to form an encapsulation space, within which both the functional segment 200 and the matrix segment 100 are located. Exemplarily, a plurality of matrix strips 110 may fill the encapsulation space.

[0172] In some embodiments, the matrix segment 100 includes an outer sheath 120, which is wound to form an accommodating space with openings at both ends along a first direction, and a plurality of matrix strips 110 are accommodated within the accommodating space; the wrapping layer wraps at least a portion of the functional segment 200 and at least a portion of the outer sheath 120.

[0173] For example, the wrapping layer may wrap a portion of functional segment 200 and a portion of outer wrapping layer 120. The wrapping layer may also wrap a portion of functional segment 200 and the entirety of outer wrapping layer 120. Alternatively, the wrapping layer may wrap the entirety of functional segment 200 and a portion of outer wrapping layer 120. Alternatively, the wrapping layer may wrap the entirety of functional segment 200 and the entirety of outer wrapping layer 120.

[0174] Multiple matrix strips 110 are housed within the accommodating space, that is, the outer sheath 120 wraps around multiple matrix strips 110 to constrain the matrix strips 110.

[0175] In some embodiments, the multiple substrate strips 110 may not be bonded together with adhesive material, but rather the multiple substrate strips 110 may be bound together by an outer sheath 120, and the substrate strips 110 may be constrained by friction to prevent the substrate strips 110 from coming out of the receiving space.

[0176] In this embodiment, the outer layer 120 is used to constrain the matrix strip 110, and the wrapping layer connects the matrix segment 100 and the functional segment 200 into a whole.

[0177] The material of the wrapping layer is not limited, but includes, but is not limited to, cigarette paper or other materials.

[0178] The material of the outer layer 120 is not limited, but includes, but is not limited to, cork paper or other materials.

[0179] The number of function segments 200 can be one or more.

[0180] In some embodiments, at least two functional segments 200 have the same function. In other embodiments, at least two functional segments 200 have different functions. That is, functional segments 200 with different functions can be combined according to different needs such as filtration and flavor enhancement.

[0181] In some embodiments, multiple functional segments 200 may be arranged sequentially along a first direction, and all of them are located at the downstream end of the matrix segment 100.

[0182] In some embodiments, one of the multiple functional segments 200 is located at the upstream end of the matrix segment 100, and the remaining functional segments 200 are located at the downstream end of the matrix segment 100 and are arranged sequentially along a first direction.

[0183] It is understood that in embodiments with multiple functional segments 200, the wrapping layer can wrap all functional segments 200 to achieve the connection of functional segments 200.

[0184] In some embodiments, please refer to Figure 10 The functional section 200 includes a cooling section 220, which is used to reduce the temperature of the aerosol. This makes the aerosol suitable for users to inhale, avoiding the problem of "scalding the mouth".

[0185] In some embodiments, please refer to Figure 10 Functional section 200 includes a filter section 210 for filtering aerosols. Exemplarily, filter section 210 can block substances of a target particle size and can also adjust the suction resistance. For example, filter section 210 can filter large-diameter particles, similar to powdery substances. Aerosols filtered through filter section 210 have a higher particle size uniformity and a smoother taste.

[0186] In some embodiments, please refer to Figure 10 The functional section 200 includes a front plug section 230, which can directly contact the matrix section 100. The main function of the front plug section 230 is to clean and prevent the matrix section 100 from falling off.

[0187] In some embodiments, please refer to Figure 10 The fore plug section 230, the matrix section 100, the cooling section 220 and the filter section 210 are connected sequentially along the first direction.

[0188] Regarding the heat-resistant, non-combustible matrix segment 100, embodiments of this application also provide an aerosol generation system, including an aerosol generation device and an aerosol generation article 1000 as described in any embodiment of this application. The aerosol generation device includes a heating element for heating the aerosol generation article 1000 to generate aerosols.

[0189] Specifically, the heating element heats the substrate section 100 to generate an aerosol.

[0190] The specific type of heating element is not limited. For example, heating elements include, but are not limited to, resistance heating or infrared heating, etc.

[0191] It should be noted that the direction in which the aerosol generating product 1000 is inserted into the aerosol generating device and the direction in which the aerosol generating product 1000 is removed from the aerosol generating device are both parallel to the first direction.

[0192] Please see Figure 12This application provides a manufacturing method for manufacturing the matrix strip 110 in any embodiment of this application. The manufacturing method includes:

[0193] S100, the extrusion channel through which the slurry enters the molding die;

[0194] S200, the slurry flows along the extrusion channel of the molding die to the discharge port of the molding die, wherein the flow rate of the slurry is different at at least two positions of the discharge port or the flow rate is different at at least one position of two adjacent discharge ports;

[0195] S300, the slurry is extruded through the outlet to form the matrix strip.

[0196] The cross-sectional shape of the substrate strip 110 and the discharge port 2000 (see [reference]). Figure 11 The shapes of the substrate strip 110 and the outlet 2000 are basically the same, that is, the cross-sectional shape of the substrate strip 110 is the same as that of the outlet 2000, and the areas are equal.

[0197] The molding die is suitable for forming matrix strips 110 by an extrusion process.

[0198] Specifically, the discharge port 2000 is connected to the extrusion channel and is located downstream of the extrusion channel along the direction of slurry travel. The slurry is extruded from the discharge port 2000 under extrusion pressure and extrusion temperature.

[0199] Understandably, extrusion pressure and extrusion temperature can be set according to requirements.

[0200] The slurry has different flow velocities at at least two locations at the outlet 2000. This could mean that the flow velocities are different at two, three, four, or more locations at the outlet 2000.

[0201] The location of the discharge port 2000 refers to any point or area in the space enclosed by the wall of the discharge port 2000.

[0202] The flow velocities at at least one location of two adjacent discharge ports 2000 are different. This could mean that the flow velocities are different at one, two, or more locations of two adjacent discharge ports 2000. For example, the flow velocities could be different at all locations of two adjacent discharge ports 2000.

[0203] It should be noted that the flow rate may be different at at least one position of two adjacent outlets 2000, but the flow rate may be the same at different positions of an outlet 2000, and a curved matrix strip 110 can still be extruded.

[0204] The manufacturing method provided in this application embodiment involves a discharge port 2000 where the flow rate of the slurry is different at at least two locations within the discharge port 2000. The slurry flow rate is faster at at least one location and slower at the other. This flow rate gradient generates transverse shear stress, i.e., shear stress in the direction intersecting the slurry's travel direction, causing asymmetrical tension within the slurry. At the instant the slurry is extruded from the discharge port 2000, the different flow rates at different locations within the discharge port 2000 cause the matrix strip 110 extruded from the discharge port 2000 to bend towards the side with the relatively lower flow rate, generating an initial curvature. After extrusion, the temperature of the slurry decreases, the elastic stress of the material is slowly released, and the bent shape of the matrix strip 110 is shaped and solidified. For two adjacent discharge ports 2000, the slurry at at least one location of one discharge port 2000 has a faster flow rate and the slurry at at least one location of the other discharge port 2000 has a slower flow rate. The slower-flowing matrix strip 110 contacts and pulls the faster-flowing matrix strip 110, causing the faster-flowing discharge port 2000 to extrude and form a curved matrix strip 110.

[0205] In some embodiments, for a single outlet 2000, the percentage of the velocity range to the average velocity at the outlet 2000 can be greater than or equal to 20%. Preferably, the percentage of the velocity range to the average velocity can be greater than or equal to 30%. Thus, the bending phenomenon of the extruded matrix strip 110 is more pronounced.

[0206] For a discharge port 2000, the velocity range is the difference between the maximum and minimum flow velocities at the discharge port 2000. Specifically, the discharge port 2000 can have multiple locations, and the corresponding flow velocity can be measured at each location. The difference between the maximum and minimum flow velocities is the range, and the arithmetic mean of the multiple flow velocities is the average flow velocity.

[0207] In some embodiments, for two adjacent outlets 2000, the percentage of the velocity range between the two adjacent outlets 2000 and the average velocity can be greater than or equal to 20%. Preferably, the percentage of the velocity range between the two adjacent outlets 2000 and the average velocity can be greater than or equal to 30%. Thus, the bending phenomenon of the extruded matrix strip 110 is more prominent.

[0208] For two adjacent discharge ports 2000, the velocity range refers to the difference between the maximum and minimum flow velocities of the two discharge ports 2000. Specifically, the two discharge ports 2000 can have multiple locations, and the corresponding flow velocity can be measured at each location. The difference between the maximum and minimum flow velocities is the range, and the arithmetic mean of the multiple flow velocities is the average flow velocity.

[0209] In some embodiments, the flow rate of the slurry at the outlet 2000 is from 0.5 m / min to 10 m / min.

[0210] For example, the flow rate of the slurry at the outlet 2000 is 0.5 m / min, 0.8 m / min, 1.0 m / min, 1.5 m / min, 2.0 m / min, 2.5 m / min, 3.0 m / min, 4.0 m / min, 5.0 m / min, 6.0 m / min, 7.0 m / min, 8.0 m / min, 9.0 m / min, or 10.0 m / min, etc.

[0211] In this embodiment, the flow rate of the slurry at the outlet 2000 is appropriate, and the slurry can cool down and solidify in time when it flows out of the outlet 2000 to maintain the curved shape, while also taking into account the production efficiency requirements.

[0212] In some embodiments, the distance between two adjacent discharge ports 2000 is 0.2 mm to 2 mm. For example, the distance between two adjacent discharge ports 2000 is 0.2 mm, 0.5 mm, 1.0 mm, 1.5 mm, 1.8 mm, or 2 mm, etc.

[0213] In this embodiment, the distance between two adjacent outlets 2000 is very close, and the matrix strips 110 extruded from the two adjacent outlets 2000 will contact each other. The matrix strip 110 of one outlet 2000 has a relatively fast flow rate, while the matrix strip 110 of the other outlet 2000 has a relatively slow flow rate. The relatively slow matrix strip 110 pulls the relatively fast matrix strip 110, so that the relatively fast matrix strip 110 forms a fourth matrix strip 110, that is, a folded matrix strip 110.

[0214] In some embodiments, the distance between the two outlets 2000 of the molding die can be greater than 2 mm. In this way, the matrix strips 110 flowing out of the two outlets 2000 do not contact each other, and can each form a matrix strip 110 with at least one curved portion.

[0215] In some embodiments, the outlet 2000 may be polygonal in shape, and may have different flow velocities at at least two corners of the polygon.

[0216] In some embodiments, the outlet 2000 is triangular in shape, and the flow velocities at the two corners of the triangle may be different.

[0217] In some embodiments, the outlet 2000 is hexagonal in shape, and the flow velocities at at least two corners of the hexagon may be different.

[0218] In some embodiments, please refer to Figure 1 and Figure 11The outlet 2000 is rectangular in shape. Thus, the cross-sectional shape of the substrate strip 110 is rectangular.

[0219] In some embodiments, the long side of the rectangular discharge port 2000 has a length of 0.6mm-1.5mm, and the short side has a length of 0.10mm-0.30mm. This results in a substrate strip 110 with a rectangular cross-section, the width of which is 0.60mm-1.50mm, and the thickness which is 0.10mm-0.30mm.

[0220] In some embodiments, the extrusion channel has a first flow section, the shape of which is different from the shape of the discharge port 2000.

[0221] The shape of the first flow cross section is used to change the flow rate of the slurry at different positions in the extrusion channel. The change in the local area of ​​the first flow cross section changes the flow rate of the slurry flowing through it. The shape of the outlet 2000 is used to define the shape of the cross section of the matrix strip 110. In this way, by using the different shapes of the first flow cross section and the outlet 2000, the flow rates at at least two positions of the outlet 2000 are different.

[0222] In some embodiments, a discharge port 2000 is formed on one end face of the molding die along the second direction, and an extrusion channel penetrates the other end face of the molding die along the second direction to form a feed port, which is a first flow section. That is, by utilizing the difference between the shape of the feed port and the shape of the discharge port 2000, the flow velocity of the slurry at at least two positions of the discharge port 2000 is changed, so that the flow velocities at at least two positions of the discharge port 2000 are different.

[0223] In some embodiments, the distance between the first flow section and the outlet 2000 is 1 mm to 3 mm. For example, the distance between the inlet and the outlet 2000 is 1 mm to 3 mm.

[0224] In this embodiment, the slurry enters the extrusion channel from the feed port. The first flow section is used to form a velocity difference. The slurry is viscous and is affected by external forces such as friction during the flow process. If the flow path between the first flow section and the outlet 2000 is too long, the velocity difference formed by the first flow section will easily decrease during the flow process, making it difficult to form a velocity difference at different positions of the outlet 2000. If the flow path between the first flow section and the outlet 2000 is too short, the velocity difference at different positions of the outlet 2000 will easily be too small. The flow path of the slurry between the first flow section and the outlet 2000 is approximately 1mm to 3mm. The path is suitable and can effectively control the velocity difference at different positions of the outlet 2000 to meet the design requirements, such as not less than 20%, thereby forming the curved matrix strip 110.

[0225] In some embodiments, the molding die has a plate-like structure, and the dimension of the molding die along the second direction is 1 mm to 3 mm. Specifically, the distance between the inlet and outlet 2000 is 1 mm to 3 mm.

[0226] In this embodiment, the molding die is generally a flat sheet structure with a dimension of 1mm to 3mm along the first direction. The slurry enters the extrusion channel from the feed port, with a flow path of approximately 1mm to 3mm, and is then extruded through the discharge port 2000 to form a curved matrix strip 110. Thus, the flow velocities at at least two locations of the feed port are different. During the flow of the slurry in the extrusion channel, because the molding die has a dimension of 1mm to 3mm along the first direction and a suitable flow path, the flow velocity difference at different locations of the discharge port 2000 can be well controlled to meet the design requirements, forming the curved matrix strip 110.

[0227] To more clearly illustrate the manufacturing method of this application, the following describes the manufacturing method of the matrix strip 110 with different bending shapes in the embodiments of this application, taking the shape of the discharge port 2000 as a rectangle as an example.

[0228] Please see Figure 11 The rectangular discharge port 2000 has a first position, a second position, a third position, a fourth position, a fifth position, and a sixth position. The first, third, fourth, and sixth positions are the four corners of the rectangle; the second position is the midpoint of one of the long sides of the rectangle, located between the first and third positions; and the fifth position is the midpoint of the other long side of the rectangle, located between the fourth and sixth positions. The flow velocity at the first position is denoted by V1, the flow velocity at the second position by V2, the flow velocity at the third position by V3, the flow velocity at the fourth position by V4, the flow velocity at the fifth position by V5, and the flow velocity at the sixth position by V6.

[0229] A curved matrix strip 110 can be obtained if the flow rate of at least one of V1 to V6 is higher or lower than the reference flow rate, for example, the percentage of the flow rate change relative to the reference flow rate is between 5% and 50%.

[0230] For ease of description, in the following examples, the reference flow rate is represented as 1, and other flow rates are represented as multiples of the reference flow rate. It is understood that the reference flow rate can be between 0.5 m / min and 10 m / min, for example, the reference flow rate can be 1 m / min. Each embodiment of Examples 1 to 5 uses one outlet 2000, and Example 6 uses multiple outlets 2000.

[0231] Example 1

[0232] In Example 1, the serial numbers are Examples 1 to 5. In each example, by changing the flow rate of at least one of V1 to V6, a first matrix strip 110, i.e. a matrix strip 110 with a sine wave, is manufactured. For specific parameters, please refer to Table 1.

[0233] Table 1

[0234] Serial Number / Flow Rate V1 V2 V3 V4 V5 V6 Example 1 1 1 1 1.1 1.3 1.5 Example 2 1 1 1 1 1.1 1.5 Example 3 1 1 1 1 0.9 0.6 Example 4 1 1 1 0.9 0.7 0.5 Example 5 1 1 0.9 1 0.9 0.6

[0235] Table 1 shows that the variation of the flow rate from the reference flow rate in at least one of Examples 1 to 5, V1 to V6, is 0%-50%. The first matrix strip 110 can be manufactured in all Examples 1 to 5. The fill rate of the matrix segment 100 using the first matrix strip 110 can reach 3.0 cm. 3 / g to 5.0cm 3 / g.

[0236] Example 2

[0237] In Example 2, numbered 6 to 10, a second matrix strip 110, i.e. a spring-shaped matrix strip 110, is manufactured by changing the flow rate of at least one of V1 to V6 in each example. For specific parameters, please refer to Table 2.

[0240] Table 2 shows that in Examples 6 to 10, by simultaneously increasing the slurry flow rate at two opposite corner positions, for example, increasing the flow rate at V1 and V6 while keeping the flow rate at other positions constant or decreasing; or, for example, increasing the flow rate at V3 and V4 while keeping the flow rate at other positions constant or decreasing, a spring-like matrix strip 110 with greater curl can be formed. Examples 6 to 10 can all produce a second matrix strip 110. The filling rate of the matrix segment 100 using the second matrix strip 110 can reach 5.0 cm. 3 / g to 6.0cm 3 / g.

[0245] Table 3 illustrates Examples 11 to 17, where increasing the flow velocity at two locations on the short side of the rectangle—for example, increasing V1 and V4 while keeping the flow velocity at other locations constant or decreasing; or, for example, increasing V3 and V6 while keeping the flow velocity at other locations constant or decreasing—can form a third matrix strip 110 with one side of the width exhibiting a pleated, curved shape 114. The fill rate of the matrix segment 100 using the third matrix strip 110 can reach 4.0 cm. 3 / g to 6.0cm 3 / g.

[0246] Example 4

[0247] In Example 4, numbered Examples 18 to 19, a third matrix strip 110 with pleated bends 114 on both sides along the width direction is manufactured by changing the flow rate of at least one of V1 to V6 in each example. For specific parameters, please refer to Table 4.

[0250] Table 4 shows that in Examples 11 to 17, increasing the flow velocity at the four corner positions of the two short sides of the rectangle, for example, increasing V1, V4, V3, and V6, while keeping the flow velocity at other positions unchanged or decreasing, can form a third matrix strip 110 with two sides in a pleated, curved shape 114 in the width direction. The fill rate of the matrix segment 100 using the third matrix strip 110 can reach 4.0 cm. 3 / g to 6.0cm 3 / g.

[0251] Example 5

[0252] In Example 5, numbered 20 to 21, a third matrix strip 110 with a pleated bend 114 on one side along the thickness direction is manufactured by changing the flow rate of at least one of V1 to V6 in each example. For specific parameters, please refer to Table 5.

[0255] Table 5 shows that in Examples 20 and 21, increasing the flow velocity at the two midpoints of the long side of the rectangle, for example, increasing V2 and V5, while keeping the flow velocity at other locations constant or decreasing, can form a third matrix strip 110 with a pleated bend 114 on one side in the thickness direction. The fill rate of the matrix segment 100 using the third matrix strip 110 can reach 4.0 cm. 3 / g to 6.0cm 3 / g.

[0256] Example 6

[0257] In Example 6, unlike the previous examples which all used a single outlet 2000, Example 6 uses thirteen outlets 2000. The fourth matrix strip 110, i.e., the folded matrix strip 110, is formed by utilizing the different flow rates of two adjacent outlets 2000. The thirteen outlets 2000 are numbered from outlet 1 to outlet 13, and outlets 1 to 13 are sequentially adjacent. For specific parameters, please refer to Table 6.

[0258] Table 6

[0259]

[0260]

[0261] Table 6 shows the flow rate at each position from outlet 1 to outlet 13, and also shows the matrix strip 110 formed corresponding to each outlet 2000. By controlling the flow rate of two adjacent outlets 2000, for example, if the flow rate of one of the two adjacent outlets 2000 is greater than the flow rate of the other, the matrix strip 110 extruded from the outlet 2000 with the faster flow rate is subject to the adhesion resistance of the other matrix strip 110 with the slower flow rate. The fourth matrix strip 110 extruded from the outlet 2000 with the faster flow rate is the folded matrix strip 110.
