Description

Technical Field

[0001] The present application relates to the technical field of smoking products, and in particular to an aerosol generating substrate segment and an aerosol generating product. Background Art

[0002] The aerosol-generating substrate segment can form an aerosol by ignition or by heat-without-burn (HNB). In a heat-without-burn aerosol-generating substrate segment, the aerosol-generating substrate segment is heated by an external heat source to a degree sufficient to emit an aerosol. The aerosol-generating substrate segment does not burn, but is loaded with a smoke agent. During use, the smoke agent is released by heating the aerosol-generating substrate segment to form an aerosol.

[0003] In the related art, the shapes of aerosol-generating matrix segments mainly include thin sheets, filaments, loose particles, and integrated porous columns. Due to their own structural reasons, these aerosol-generating matrix segments are difficult to ensure that the amount of aerosol released remains consistent in the front, middle and back sections of the puff during the heating process. The consistency of the puff is difficult to achieve an ideal state, and the puffing experience is poor. Summary of the Invention

Therefore, by combining matrix strips with different cross-sectional dimensions, the filling rate, density and porosity of the aerosol-generating matrix segment can be controlled and designed, which is conducive to matching different heating components and heating methods. For example, an aerosol-generating matrix segment with a high porosity can be more suitable for heating by an infrared heating component, and infrared light can more easily penetrate the matrix strips to reach the interior of the aerosol-generating matrix segment, quickly generating aerosol, thereby improving the heating efficiency of the heating component, improving the uneven heating of the aerosol-generating matrix segment, improving the uniformity of puff by puff, and thereby improving the puffing experience. In addition, porosity can change the airflow channel within the aerosol-generating matrix segment. By controlling and designing the porosity, a better smoke volume and taste can be obtained. By controlling and designing the density levels, the initial smoke volume and satisfaction can be increased, and the consistency of the smoking taste can be improved.

[0084] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

[0085] The heating component of the aerosol generating device heats the aerosol generating matrix segment 10, causing the aerosol generating matrix segment 10 to release aerosol. The user inhales the aerosol one puff at a time, that is, the user inhales one puff of the aerosol, stops inhaling, and then inhales the next puff of the aerosol, and in this way, the user inhales intermittently. The front section of the inhalation refers to the period of initial use of the aerosol generating matrix segment 10, and the first few puffs correspond to the front section of the inhalation, for example, 1-5 puffs; the back section of the inhalation refers to the period when the aerosol generating matrix segment 10 is close to complete aerosol release, and the last few puffs correspond to the back section of the inhalation, for example, the last 1-5 puffs. The front section and back section of the inhalation refer to the early and late sections of the service life of the aerosol generating matrix segment 10, respectively. The middle section of the inhalation refers to the inhalation period between the front section and the back section.

[0086] In the description of this application, the orientation or position relationship of "first direction", "extension direction", "length direction", "second direction" and "third direction" is based on the attached Figure 1 , Attachment Figure 16 , Attachment Figure 17 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0087] The present application embodiment provides an aerosol generating matrix segment, see Figures 1 to 14 The aerosol generating substrate segment 10 includes at least two substrate strips 11 arranged in parallel. The aerosol generating substrate segment 10 includes two opposite ends. The substrate strips 11 extend from one end to the other end of the aerosol generating substrate segment 10. In a cross section perpendicular to the extension direction of the substrate strips, at least some of the substrate strips 11 have a different cross-sectional size from other substrate strips 11.

[0088] The direction in which the matrix strips 11 extend can be defined as a first direction. Parallel arrangement means that the projections of the matrix strips 11 at least partially overlap, with a plane parallel to the first direction serving as the projection plane. In other words, the matrix strips 11 are not arranged end-to-end in sequence along the first direction, but are instead arranged approximately side by side. In other words, the matrix strips are approximately parallel and approximately parallel to the central axis of the aerosol-generating matrix segment 10. If the aerosol-generating matrix segment 10 is cylindrical, the central axis is the central axis of the cylinder. If the aerosol-generating matrix segment 10 is a rectangular parallelepiped, the central axis is its axis of symmetry.

[0089] It should be noted that due to the manufacturing and assembly process and precision, it is difficult to achieve absolute parallelism between the matrix strips 11. There will be a certain angle of inclination, or some matrix strips will bend to a certain extent. Therefore, in some embodiments, each matrix strip 11 extends along a first direction, and the angle between the first direction and the central axis of the aerosol generating matrix segment is not greater than 10 degrees.

[0090] In one embodiment, the first direction is parallel to the axial direction, that is, the included angle is 0 degree.

[0091] It is understandable that, in some embodiments, the extension direction of the aerosol generating substrate segment 10 may be defined as a first direction, and each substrate strip 11 is substantially parallel to the first direction.

[0092] Please continue reading Figures 1 to 8 At least some of the substrate strips 11 have different cross-sectional dimensions from other substrate strips 11, meaning that the aerosol-generating substrate segment 10 includes substrate strips 11 having at least two different cross-sectional dimensions. For example, the substrate strips 11 may include at least first substrate strips 111 and second substrate strips 112, where the cross-sectional dimensions of the second substrate strips 112 are larger than those of the first substrate strips 111. In other words, the substrate strips 11 may consist of only the first substrate strips 111 and the second substrate strips 112, or may include substrate strips 11 having other cross-sectional dimensions in addition to the first substrate strips 111 and the second substrate strips 112.

[0093] The first matrix strip 111 and the second matrix strip 112 are both matrix strips 11 , and are distinguished in name only for the convenience of description.

[0094] The volume ratio of the first matrix strips 111 and the second matrix strips 112 in the aerosol generating matrix segment 10 can be designed as needed. For example, the volume ratio of the first matrix strips 111 and the second matrix strips 112 in the same aerosol generating matrix segment 10 can be 1:15-5:1 (including endpoint values), such as 1:15, 1:10, 1:5, 2:3, 1:1, 2:1, 3:1, 5:1, etc.

[0095] The ratio of the number of the first substrate strips 111 to the second substrate strips 112 in the aerosol-generating substrate segment 10 can be set as needed. For example, the ratio of the number of the first substrate strips 111 to the second substrate strips 112 in the same aerosol-generating substrate segment 10 can be 1:10-10:1 (inclusive), such as 1:10, 1:8, 1:5, 1:3, 1:1, 2:3, 2:1, 3:1, 5:1, 8:1, 10:1, etc. Preferably, it is 1:3-3:1 (inclusive).

[0096] In one embodiment, please continue to refer to Figures 1 to 14 The aerosol generating substrate segment 10 further includes a packaging layer 12 , which is rolled up to form a receiving space, and all substrate strips 11 are received in the receiving space.

[0097] The packaging layer 12 can be a hollow tube, and all the substrate strips 11 are accommodated in the accommodating space of the packaging layer 12. The packaging layer 12 can also be a plugging paper, and all the substrate strips 11 are combined into an integrated structure by the plugging paper. The packaging layer 12 can shape and protect the substrate strips 11.

[0098] The filling ratio of the substrate strips 11 in the aerosol-generating substrate segment 10 can be set as needed. For example, the filling ratio of the substrate strips 11 in the aerosol-generating substrate segment 10 can range from 40% to 90% (inclusive), such as 40%, 50%, 60%, 70%, 80%, 90%, etc. The filling ratio is the ratio of the sum of the volumes of all the substrate strips to the volume of the accommodation space within the aerosol-generating substrate segment 10.

[0099] Exemplarily, the cross-sectional size of the matrix strip 11 can be 0.4 mm-7 mm (including the endpoint values). Taking the cross-sectional shape as a circle as an example, the diameter is 0.4 mm-7 mm (including the endpoint values), such as 0.4 mm, 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, 2 mm, 3 mm, 3.5 mm, 4 mm, 5 mm, 6 mm or 7 mm, etc.

[0100] More preferably, the cross-sectional dimensions of substrate strip 11 can be 0.5mm-3.5mm (including endpoint values), for example, the diameter is 0.5mm-3.5mm (including endpoint values), for example: 0.55mm, 0.6mm, 0.55mm, 0.65mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm, 3.5mm, more preferably, the diameter of substrate strip 11 can be 0.6mm-1.5mm (including endpoint values). It is to be understood that when the cross-sectional shape is other shapes, the cross-sectional dimension can be considered to be the side length of an equivalent diameter or a polygon.

[0101] The number of matrix strips 11 in each aerosol-generating matrix segment 10 can be set as needed. For example, the number of matrix strips 11 in each aerosol-generating matrix segment 10 can be 2-45 (including endpoint values), such as 2, 5, 8, 10, 15, 20, 30, 35, 36, 37, 40 or 45, etc.

[0102] Preferably, the number of matrix strips 11 in each aerosol-generating matrix segment 10 may be 20-40 (inclusive). Even more preferably, the number of matrix strips 11 in each aerosol-generating matrix segment 10 may be 25-38 (inclusive). This structural configuration has higher molding efficiency, and its porosity distribution and proportion are very beneficial to heating efficiency and puffing taste.

[0103] The specific structure of the matrix strip 11 is not limited herein. For example, in one embodiment, the matrix strip 11 can be made of the atomizing medium itself, such as a smoke-flavoring flavoring medium. In other embodiments, the matrix strip 11 can also include a substrate and the atomizing medium disposed on the substrate. The substrate can be, for example, one or more of high-temperature-resistant carbon fiber, softwood pulp fiber, hardwood pulp fiber, bamboo fiber, cotton fiber, or hemp fiber. The provision of the substrate can improve the strength of the matrix strip 11 while also allowing it to withstand a certain degree of high temperature without generating odor.

[0104] The specific components of the matrix strip 11 are not limited here. For example, in one embodiment, the matrix strip 11 may include plant components, auxiliary components, smoke-generating agent components, adhesive components, etc.

[0105] In one embodiment, the plant component is one or more combinations of powders formed from crushed tobacco leaves, tobacco leaf fragments, tobacco stems, tobacco dust, and flavorful plants. The plant component is the core source of the flavor of the product. Endogenous substances in the plant component, such as nicotine, enter the human bloodstream through aerosolization, promoting dopamine production in the pituitary gland, thereby achieving a sense of physiological satisfaction.

[0106] In one embodiment, the plant components may include one or more of tobacco, tea leaves, tea stems, dandelion, eucalyptus, cloves, cinnamon, turmeric, fungi, insulin wood, astragalus, jujube seeds, lentils, kudzu root, fennel, rosemary, star anise, honeysuckle, chrysanthemum, rose, marigold, mugwort, olive, ginseng, American ginseng, mung beans, red beans, tangerine peel, nut shells, lily, coffee, agarwood, mint, hawthorn, licorice, cocoa, fungus, lotus seeds, lotus leaves, zingiber officinale, ginger, buckwheat, and wheat bran. The mass proportion of the plant components in the aerosol matrix can be 20%-80% (including the endpoint values).

[0107] In one embodiment, the auxiliary agent may be one or more combinations of inorganic fillers, lubricants, and emulsifiers. Inorganic fillers include one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. Inorganic fillers can provide skeletal support for the plant component and, while also possessing micropores, can increase the porosity of the wall material after the plant component is formed, thereby improving the aerosol release rate.

[0108] Lubricants include one or more of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase particle flowability, reduce friction between particles, and achieve a more uniform particle density. They can also reduce mold pressure and reduce mold wear.

[0109] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can, to a certain extent, slow the loss of flavoring substances during storage, increase their stability, and improve the sensory quality of the product. Emulsifiers (also known as surfactants) can reduce the interfacial tension between the water-soluble and water-insoluble components in a mixed system and form a relatively strong film on the surface of the droplets. Alternatively, due to the charge imparted by the emulsifier, a double layer is formed on the surface of the droplets, preventing the droplets from aggregating and maintaining a uniform emulsion. Emulsifying and homogenizing two immiscible components can improve the consistency of product quality.

[0110] The function of the smoke-generating agent component is to generate a large amount of vapor when heated, thereby increasing the amount of smoke produced by the smoking article. In one embodiment, the smoke-generating agent may include, for example, a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butylene glycol, and glycerol); an ester of a polyhydric alcohol (such as glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid), or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butylene glycol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, triactin, meso-erythritol, a mixture of diacetyl glycerides, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, tributyrin, and lauryl acetate).

[0111] In one embodiment, the adhesive component is a natural plant-extracted, non-ionically modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive wetting and intimately contacting the product component materials creates intermolecular attraction, thereby bonding the powders and liquids of the component materials. The use of a natural plant-extracted, non-ionic adhesive can prevent the release of harmful substances such as methanol, formaldehyde, and acrolein caused by colloid modification, thereby improving the safety of the product.

[0112] The matrix strip 11 can be a particle combination, which is a reconstituted tobacco medium, for example, a reconstituted tobacco medium containing ingredients such as a smoke-generating agent and tobacco. The matrix strip 11 is an integrated structure, for example, an integrated structure that can be formed by injection molding, compression molding or extrusion. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the material is pushed forward by the screw or piston through the extruder barrel and the screw or piston, and continuously passes through the die to form various cross-section products or semi-finished products.

[0113] For example, a plurality of matrix strips 11 can be extruded simultaneously by an extruder, and the matrix strips 11 are dried and shaped by a drying device. After shaping, the matrix strips 11 are first oriented and arranged, and then formed into an aerosol-generating matrix segment 10 by a winding rod.

[0114] Since the matrix strips 11 are a combination of particles, the aerosol-generating matrix segment 10 formed by multiple matrix strips 11 is an integrated medium after being heated and inhaled or after the heating stops, and is not prone to disintegration and falling off. This solves the problems of the aerosol-generating matrix segment 10 in the prior art, such as loose flakes, falling off of filamentous components and particle components, and difficulty in cleaning, which occur in the aerosol-generating matrix segment 10 of thin flakes, filaments or loose particles.

[0115] The cross-sectional dimensions of the matrix strip 11 (i.e., the cross-sectional dimensions perpendicular to the first direction) are not limited. The cross-sectional dimensions here may be a cross-sectional area. For example, the cross-sectional area of ​​the matrix strip 11 may be a polygonal area (including but not limited to a triangle, a prism, and a Figure 12 square shown, etc.), Figure 13 The oval shown, Figure 14 Shown petal shape etc., petal shape refers to the closed figure that is formed by circle and the multiple arc combinations that surround the circular circumference side.In addition, the shape of the cross section of matrix bar 11 can also be circle, oval, gear-shaped and special-shaped etc., oval is meant that cross the center of circle a circle is divided into two semicircular arcs and mutually reverse translation, with two equal length parallel lines the end points of two semicircular arcs are connected and the closed figure that forms, and special-shaped refers to other symmetry or asymmetric shape outside the above enumerated shape.

[0116] The substrate strips 11 in the aerosol-generating substrate segment 10 may all have the same cross-sectional shape (see Figures 1 to 10 ), or two or more different cross-sectional shapes (see Figure 11 ).

[0117] The cross-sectional dimensions of the matrix strip 11 can be set as needed, wherein the cross-sectional dimensions refer to the dimensions used to define the outer contour of the cross section of the matrix strip 11. For example, if the cross section of the matrix strip 11 is circular, the cross-sectional dimensions are the diameter of the cross section of the matrix strip 11. If the cross section of the matrix strip 11 is square, the cross-sectional dimensions are the maximum length of the cross section of the matrix strip 11. If the cross section of the matrix strip 11 is a shape other than circular and square, the cross-sectional dimensions are the maximum dimension of the cross section of the matrix strip 11, that is, the distance between the two farthest points on the outer contour of the cross section.

[0118] The shape of the aerosol-generating substrate segment 10 is also not limited. For example, the aerosol-generating substrate segment 10 can be cylindrical. The cross-section of the cylindrical aerosol-generating substrate segment 10 can also be polygonal (including but not limited to triangle, prism, and square), elliptical, petal-shaped, circular, oval, gear-shaped, or irregularly shaped.

[0119] The present application also provides an aerosol generating product 1, see Figure 16 and Figure 17 The aerosol-generating article 1 includes a functional segment 20, an outer wrapping layer 30 and the aerosol-generating substrate segment 10 provided in any embodiment of the present application.

[0120] The functional segment 20 is disposed at at least one end of the aerosol-generating substrate segment 10 along the first direction. The functional segment 20 includes a cooling segment 21 and a filtration segment 22. The cooling segment 21 is located between the filtration segment 22 and the aerosol-generating substrate segment 10. The outer wrapping layer 30 wraps around the outer periphery of the functional segment 20 and the aerosol-generating substrate segment 10.

[0121] The aerosol generating article 1 is used in conjunction with an aerosol generating device having a heating component. Specifically, the heating component heats and atomizes the aerosol generating substrate segment 10 to generate an aerosol, and the user inhales the filtered aerosol through the filter segment 22.

[0122] The heating assembly can be heated in a variety of ways. Exemplarily, these methods include central heating and circumferential heating. Central heating involves inserting the heating assembly into the aerosol-generating matrix segment 10 to heat the aerosol-generating matrix segment 10 from the inside out. Circumferential heating involves placing the heating assembly around the periphery of the aerosol-generating article 1 to heat the aerosol-generating matrix segment 10 from the outside in. These heating methods may include resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, and the like, without specific limitation herein.

[0123] The cooling section 21 is arranged between the filtering section 22 and the aerosol generating matrix section 10, and is used to cool the aerosol before the filtering section 22 filters the aerosol, so as to reduce the temperature of the aerosol and improve the "burning mouth" phenomenon when the user inhales the aerosol.

[0124] The materials of the cooling section 21 include but are not limited to one or more combinations of PE (polyethylene), PLA (Polylactic acid, also known as polylactide), PBAT (butylene adipate-co-terephthalate), PP (Polypropylene), acetate fiber, and acrylic fiber materials.

[0125] The material of the filter section 22 includes but is not limited to one or more combinations of PE, PLA, PBAT, PP, acetate fiber, and acrylic fiber materials.

[0126] The materials of the cooling section 21 and the filtering section 22 may be the same or different.

[0127] It should be noted that the aerosol-generating article 1 relies on the aerosol-generating substrate segment 10 to generate aerosol, and the functional segment 20 does not generate aerosol.

[0128] The material of the outer wrapping layer 30 is not limited, for example, including but not limited to one or more combinations of fiber paper, metal foil, infrared radiation layer, metal foil composite fiber paper, polyethylene composite fiber paper, PE, PBAT and the like.

[0129] The outer wrapping layer 30 can be a hollow tube, and the aerosol generating matrix segment 10 and the functional segment 20 can be arranged in sequence in the hollow tube outer wrapping layer 30. The outer wrapping layer 30 can also be a tipping paper, and the aerosol generating matrix segment 10 and the functional segment 20 are compounded into an integrated structure through the tipping paper.

[0130] The first direction is the arrangement direction of the aerosol generating matrix segment 10, the cooling segment 21 and the filtering segment 22. The aerosol generating product 1 is inserted into the aerosol generating device along the first direction, and the aerosol generating product 1 is also taken out of the aerosol generating device along the first direction. The length of the aerosol generating matrix segment 10 along the first direction can be longer, shorter, or the same as the length in other directions.

[0131] For example, when the aerosol-generating substrate segment 10 has a cylindrical appearance, the first direction is the axial direction of the aerosol-generating substrate segment 10 . It should be noted that the axial length of the aerosol-generating substrate segment 10 may be smaller than its diameter.

[0132] For another example, when the appearance of the aerosol generating matrix segment 10 is a rectangular parallelepiped, the first direction is still the direction defined above, that is, the arrangement direction of the aerosol generating matrix segment 10, the cooling segment 21 and the filtering segment 22, or the direction of taking and placing the aerosol generating product 1 on the aerosol generating device. The first direction of the aerosol generating matrix segment 10 can be any direction of the length, width, and height of the rectangular parallelepiped.

[0133] For example, please refer to Figure 16 and Figure 17 The aerosol generating matrix segment 10, the cooling segment 21 and the filtering segment 22 can be coaxially arranged cylinders and the aerosol generating matrix segment 10 is an integrated structure. The first direction is the axial direction of the aerosol generating matrix segment 10, the cooling segment 21 and the filtering segment 22.

[0134] Exemplarily, the length dimension of the aerosol generating substrate segment 10 along the first direction can be 20%-80% (including the endpoint values) of the length dimension of the aerosol generating article 1 along the first direction, such as 20%, 30%, 40%, 50%, 60%, 70% or 80%, etc.

[0135] Illustratively, the length dimension of the cooling section 21 along the first direction can be 25%-65% (including the endpoint values) of the length dimension of the aerosol generating article 1 along the first direction, such as 25%, 28%, 30%, 35%, 40%, 50%, 55%, 60% or 65%, etc.

[0136] It is understandable that during the user's inhalation process, the aerosol generated by the aerosol-generating substrate segment 10 flows toward the filter segment 22 along the first direction.

[0137] The aerosol generating matrix segment provided in the embodiment of the present application includes at least two matrix strips 11. In the cross section perpendicular to the first direction, the cross-sectional dimensions of at least some of the matrix strips 11 are different. That is to say, the aerosol generating matrix segment 10 has both matrix strips 11 with relatively large cross-sectional dimensions and matrix strips 11 with relatively small cross-sectional dimensions. Therefore, by coordinating the matrix strips 11 with different cross-sectional dimensions, the filling rate, density and porosity of the aerosol generating matrix segment 10 can be controlled, which is conducive to matching different heating components and heating methods. For example, the aerosol generating matrix segment 10 with high porosity is more suitable for heating by an infrared heating component. Infrared light can more easily penetrate and reach the interior of the aerosol generating matrix segment 10, quickly generating aerosol, thereby improving the heating efficiency of the heating component, improving the uneven heating of the aerosol generating matrix segment 10, improving the uniformity of puff by puff, and thus improving the puffing experience. In addition, the porosity can change the airflow channel within the aerosol-generating matrix segment 10. By controlling and designing the porosity, a better smoke volume and taste can be obtained; by controlling and designing the density levels, the initial smoke volume and satisfaction can be increased, and the consistency of the smoking taste can be improved.

[0138] In some embodiments, see Figure 15 , the cross-sectional dimensions of any two positions of a single substrate strip 11 along the first direction are the same. Here, the cross-sectional dimensions of any two positions of a single substrate strip 11 along the first direction are also considered to be the same if they are within a certain error range (e.g., 0.05 mm).

[0139] That is to say, the matrix strips 11 in this embodiment are of equal diameter structure.

[0140] Of course, in other embodiments, the matrix strip 11 can also be a variable diameter structure. At least part of the region of the matrix strip 11 with a variable diameter structure has different cross-sectional dimensions on a cross section perpendicular to the first direction. In other words, the matrix strip 11 with a single variable diameter structure has different cross-sectional dimensions at at least two positions in the first direction. Exemplarily, taking the matrix strip 11 with a variable diameter structure as a cylindrical shape as an example, the diameters of at least part of the region of the matrix strip 11 with a variable diameter structure are different. The variable diameter structure design can match the temperature field distribution of the heating component in the axial direction, and the matrix strip 11 with a relatively small size is partially distributed at at least one end of the heating component in the axial direction, which is conducive to rapid smoke output and smoking consistency.

[0141] In some embodiments, see Figures 1 to 3 ,as well as Figure 9 The matrix strips 11 include first matrix strips 111 and second matrix strips 112 . The cross-sectional dimensions of the second matrix strips 112 are larger than the cross-sectional dimensions of the first matrix strips 111 . All the second matrix strips 112 surround the circumference of all the first matrix strips 111 .

[0142] The second matrix strip 112 with a larger cross-sectional size carries relatively more effective substances and has a relatively larger heat capacity, and requires relatively more energy to generate aerosol. The first matrix strip 111 with a smaller cross-sectional size carries relatively less effective substances, but has a relatively smaller heat capacity, and requires relatively less energy to generate aerosol. Therefore, based on the heat conduction and energy radiation characteristics of the heating component, the first matrix strip 111 with a smaller cross-sectional size is arranged close to the heating component, and the second matrix strip 112 with a larger cross-sectional size is arranged away from the heating component. In this way, in the initial stage of heating, the heat provided by the heating component is relatively small, but it is sufficient to ensure the heating and atomization of the first matrix strip 111 with a smaller cross-sectional size. Therefore, the first matrix strip 111 with a smaller cross-sectional size is close to the heating component to quickly release aerosol and increase the amount of smoke initially inhaled. As the heat provided by the heating component increases and the heat conduction is sufficient, the second matrix strip 112 with a larger cross-sectional size is away from the heating component and can fully release sufficient aerosol for a relatively long time, thereby improving the problem of uneven aerosol generation during the heating process. Thus, by coordinating the first and second matrix strips 111, 112, and depending on the arrangement of the first and second matrix strips 111, 112, different heating components and heating methods can be matched to improve the heating efficiency of the heating component. Furthermore, the coordination of the first matrix strips 111 with smaller cross-sectional dimensions provides more pores between the matrix strips 11 than the coordination of the second matrix strips 112 with larger cross-sectional dimensions, which is more conducive to the transmission of infrared light and uniform heating.

[0143] In this embodiment, all second matrix strips 112 with larger cross-sectional dimensions surround the circumference of all first matrix strips 111 with smaller cross-sectional dimensions, and can be coordinated with a heating component of a central heating method, especially a central infrared heating method. Heat is gradually conducted from the inside to the outside, and infrared light is radiated from the inside to the outside. In this way, the first matrix strips 111 are arranged close to the heating component and can be quickly heated and produce aerosols. Due to the penetration of infrared light, some second matrix strips 112 will also produce aerosols under infrared heating. More internal gaps are also more conducive to infrared penetration. The second matrix strips 112 are relatively far away from the heating component. As heat conduction continues and heat accumulates, the second matrix strips 112 are also continuously heated and produce aerosols, further improving the uneven heating of the aerosol-generating matrix segment 10, accelerating the first puff volume and satisfaction, improving the uniformity of puff by puff, and thereby improving the puffing experience.

[0144] It should be noted that by appropriately adjusting the size difference between the first matrix strip 111 and the second matrix strip 112, this embodiment can also be compatible with the circumferential heating method. By controlling the porosity or the composition of the matrix strips, the circumferential heating method can also have a certain effect. The specific design can be based on the heating characteristics of the heating component. Under the circumferential heating method, since heat is transferred from the outside to the inside, and since the innermost aerosol generating matrix is ​​relatively far away from the heating component, the traditional aerosol generating matrix segment often suffers from insufficient heating of the innermost aerosol generating matrix. In the above embodiment, since the inner matrix strips are relatively small in size and have a small heat capacity, the heat required to generate aerosol is also relatively small. Therefore, the problem of insufficient baking of the innermost aerosol generating matrix under the circumferential heating method can be solved, and the smoke volume and puff taste in the latter part of the puff can be significantly improved.

[0145] In other embodiments, please refer to Figure 4 、 Figure 5 and Figure 8 , all first matrix strips 111 surround the circumference of all second matrix strips 112 .

[0146] In this embodiment, all the first matrix strips 111 surround the circumferential sides of all the second matrix strips 112, and a heating component with a circumferential heating method can be used. In this way, the first matrix strips 111 are arranged closer to the heating component, and the second matrix strips 112 are arranged away from the heating component. Similarly, the uneven heating of the aerosol generating matrix segment 10 can be improved, the uniformity of each puff can be improved, and the puffing experience can be improved.

[0147] It is understandable that by appropriately adjusting the size difference between the first matrix strip 111 and the second matrix strip 112 or the composition or density of the matrix strips, this embodiment can also match the central heating method and improve the uniformity of the puff. Specifically, it can be specifically designed according to the heating characteristics of the heating component. Under the central heating method, since heat is transferred from the inside to the outside, and since the outermost aerosol generating matrix is ​​relatively far away from the heating component, the traditional aerosol generating matrix segment often suffers from insufficient heating of the outermost aerosol generating matrix. In the above embodiment, since the outermost matrix strip is relatively small in size and has a small heat capacity, the heat required to generate aerosol is also relatively small. Therefore, the problem of insufficient baking of the outermost aerosol generating matrix under the central heating method can be solved, and the smoke volume and puff taste in the latter stage of the puff can be significantly improved.

[0148] It should be noted that the arrangement of the first matrix strips 111 and the second matrix strips 112 is not limited to the two arrangements described above. In other embodiments, the first matrix strips 111 and the second matrix strips 112 may be arranged in other predetermined arrangements or randomly arranged according to design requirements. For example, a plurality of first matrix strips 111 and a plurality of second matrix strips 112 may be randomly arranged or randomly and uniformly arranged within the aerosol generating matrix segment 10.

[0149] In some embodiments, the first matrix strip 111 and / or the second matrix strip 112 includes at least two separate segments in the first direction.

[0150] Here, the first matrix strip 111 may include at least two separate segments in the first direction, the second matrix strip 112 may include at least two separate segments in the first direction, or both the first matrix strip 111 and the second matrix strip 112 may include at least two separate segments in the first direction.

[0151] In this embodiment, by setting the first matrix strip 111 and / or the second matrix strip 112 to include at least two separate segments in the first direction, the aerosol generating matrix segment 10 can be heated in segments in the first direction, which is beneficial for the user to puff in multiple times, and each time the aerosol generating matrix segment 10 is puffed is fresh, thereby improving the situation where odor is generated due to repeated heating of old aerosol generating matrix segments 10, thereby improving the user's experience.

[0152] In the related art, the density of aerosol generating matrix segments in the form of thin sheets, filaments, loose particles, and integrated porous columns is relatively uniform, and it is difficult to design and control the density of these aerosol generating matrix segments differently. For these aerosol generating matrix segments with relatively uniform density, when the density of the aerosol generating matrix segment is relatively high, its heat capacity is large, the load of aerosol generating effective substances is relatively high, the porosity inside the aerosol generating matrix segment is low, and the aerosol generating matrix segment requires more energy to generate a large amount of smoke in the initial stage of heating, while the energy supply of the heating component in the initial stage is delayed and the energy accumulation is small, resulting in the aerosol generating matrix segment generating limited aerosol in the front section of puffing, but sufficient aerosol generated in the middle and late sections of puffing; when the density of the aerosol generating matrix segment is relatively low, its heat capacity is small, the load of aerosol generating effective substances is relatively low, the porosity inside the aerosol generating matrix segment is high, and the aerosol generating matrix segment requires less energy to generate a large amount of smoke in the initial stage of heating, and the smoke is discharged quickly, resulting in the aerosol generating matrix segment generating sufficient aerosol in the front section of puffing, and the aerosol generated in the middle and late sections of puffing showing obvious attenuation. That is to say, it is difficult to ensure that the aerosol release amount remains consistent in the front, middle and back sections of the puff during the heating process of the aerosol-generating matrix segment with a relatively uniform density. Therefore, it is difficult to ensure the consistency of the puff during the puffing process, and the puffing experience is poor. In addition, it is also difficult to achieve a radially differentiated porosity design for the aerosol-generating matrix segment in the related art, which is also detrimental to the consistency of the puffing taste, especially the inability to effectively exert the advantages of the infrared heating method. In the effect reasoning of some embodiments, the matrix strips with relatively small sizes are similar to the aerosol-generating matrix with smaller density, and the matrix strips with relatively large sizes are similar to the aerosol-generating matrix with larger density.

[0153] However, the first and second matrix strips 111, 112 of the aerosol-generating matrix segment 10 of the embodiment of the present application can have different densities. That is, the aerosol-generating matrix segment 10 includes both the second matrix strips 112, which are relatively higher in density, and the first matrix strips 111, which are relatively lower in density. Therefore, during the initial heating phase, the infrared transmission efficiency of the first matrix strips 111, which are relatively lower in density, is higher than that of the second matrix strips 112, which are relatively higher in density. Furthermore, the heat capacity of the first matrix strips 111, which are relatively lower in density, is smaller. Compared with the second matrix strips 112, the first matrix strips 111 can generate more abundant aerosol in the early stages of the puff. This advantage is more pronounced for infrared heating components. During the middle and late stages of the puff, although the aerosol generated by the first matrix strips 111 will decay, the second matrix strips 112 can still generate more abundant aerosol. Therefore, through the coordination of the first and second matrix strips 111, the amount of aerosol released can be kept roughly consistent throughout the early, middle, and late stages of the puff, thereby improving the consistency of the puff and, in turn, the puffing experience. It is understandable that the effect will be better if the hierarchical design of dielectric strips with different cross-sectional sizes is combined with the hierarchical design of density.

[0154] When the first matrix strip 111 with relatively low density is arranged on the periphery of the second matrix strip 112 with relatively high density, the aerosol generating matrix segment 10 is more suitable for a circumferential heating method. When the first matrix strip 111 with relatively low density is arranged on the inner side of the second matrix strip 112 with relatively high density, the aerosol generating matrix segment 10 is more suitable for a central heating method. In other words, the matrix strip with relatively low density is closer to the heating component, and the initial smoke output speed and smoke volume are better. In addition, the hierarchical design of density also ensures the smoke volume and satisfaction of the middle and rear sections of the suction. In addition, the matrix strip with relatively low density is arranged farther away from the heating component, which can improve the smoke volume and taste of the rear section of the suction. The specific design can be based on actual needs.

[0155] The density of the first matrix strip 111 and the second matrix strip 112 can be set as needed. For example, the density of the first matrix strip 111 can be in the range of 400mg-1300mg / cm 3 (including endpoint values), such as 400 mg / cm 3 , 500mg / cm 3 , 700mg / cm 3 , 900mg / cm 3 、1200mg / cm 3 、1300mg / cm 3 wait.

[0156] For example, the density of the second matrix strip 112 may be in the range of 900 mg / cm2 to 2000 mg / cm3. 3(including endpoint values), such as 900 mg / cm 3 、1200mg / cm 3 、1500mg / cm 3 、1800mg / cm 3 , 2000mg / cm 3 wait.

[0157] In some embodiments, the density of the first matrix strips 111 and the second matrix strips 112 may be in the range of 400 mg / cm 3 -2000mg / cm 3 (including endpoint values), the density of the first matrix strips 111 and the second matrix strips 112 can be the same or different.

[0158] In some embodiments, the bulk density of the matrix strips 11 in the aerosol-generating matrix segment 10 is 500 mg / cm 3 -1400mg / cm 3 (including 500mg / cm 3 and 1400mg / cm 3 ). Exemplarily, the bulk density of the matrix strips 11 in the aerosol-generating matrix segment 10 is 500 mg / cm 3 、600mg / cm 3 、800mg / cm 3 、1000mg / cm 3 、1300mg / cm 3 or 1400mg / cm 3 etc.

[0159] The bulk density of the substrate strips 11 is the density calculated by dividing the mass of all substrate strips 11 in an aerosol-generating substrate segment 10 by the total volume of the aerosol-generating substrate segment 10 .

[0160] There are many ways to arrange the matrix strips 11 with different cross-sectional sizes.

[0161] In some embodiments, the first matrix strips 111 and the second matrix strips 112 are arranged alternately along the radial direction outward of the aerosol-generating substrate segment 10 .

[0162] In this embodiment, since the cross-sectional dimensions and / or densities of the first matrix strips 111 and the second matrix strips 112 are different, the first matrix strips 111 and the second matrix strips 112 are arranged alternately, that is, the matrix strips 11 with different cross-sectional dimensions and / or densities are arranged alternately along the radial outward direction of the aerosol generating matrix segment 10.

[0163] For example, taking the case where the substrate strips 11 on a single trajectory are arranged in a circumferential direction around the center of the aerosol-generating substrate segment 10, and multiple trajectory lines are arranged in concentric circles along the radial direction of the aerosol-generating substrate segment 10, the density of the substrate strips 11 of the aerosol-generating substrate segment 10 can change from large to small, then from small to large, or from small to large, then from large to small, as the density moves outward from the radial direction of the aerosol-generating substrate segment 10. The cross-sectional dimensions of the substrate strips 11 of the aerosol-generating substrate segment 10 can change from large to small, then from small to large, or from small to large, then from large to small.

[0164] In some embodiments, see Figure 20 and Figure 21 , along the radial outward direction of the aerosol generating matrix segment 10, a first matrix strip 111, a second matrix strip 112 and a third matrix strip 113 are sequentially arranged, the second matrix strip 112 is arranged between the first matrix strip 111 and the third matrix strip 113, the cross-sectional dimensions of the second matrix strip 112 are larger than the cross-sectional dimensions of the first matrix strip 111 and the third matrix strip 113, and the cross-sectional dimensions of the first matrix strip 111 and the third matrix strip 113 can be the same (e.g. Figure 20 ), or different (as shown in Figure 21 As shown). The aerosol generating matrix segment 10 of this structure can be applied to both circumferential heating and central heating methods. The matrix strips closer to the heating component are smaller in size, which can improve the smoke output speed and smoke volume in the initial stage. The matrix strips farthest from the heating component are relatively small in size, which can improve the smoke volume and smoking satisfaction in the latter stage of smoking, and ensure the consistency of smoke volume and smoking taste before, during and after smoking. Similarly, along the radial outward direction of the aerosol generating matrix segment 10, the first matrix strip 111, the second matrix strip 112 and the third matrix strip 113 are arranged in sequence, the second matrix strip 112 is arranged between the first matrix strip 111 and the third matrix strip 113, the density of the second matrix strip 112 is greater than the density of the first matrix strip 111 and the third matrix strip 113, and the density of the first matrix strip 111 and the third matrix strip 113 can be the same or different. Of course, the effects of cross-sectional size and density can be designed in a superimposed manner, for example: the matrix strips closer to the heating component are smaller in size and have a lower density.

[0165] In some embodiments, see Figures 1 to 5 ,as well as Figures 8 to 11 Each matrix strip 11 extends along a first direction or has an inclination angle with respect to the first direction of no more than 10 degrees, and at least some of the matrix strips 11 are distributed along a plurality of trajectory lines. The matrix strips 11 on a single trajectory line are linearly arranged along a second direction, and the plurality of trajectory lines are arranged along a third direction, wherein the first direction, the second direction, and the third direction are not parallel. In some embodiments, the matrix strips 11 on a single trajectory line are arranged in parallel along the second direction.

[0166] See also Figure 1 , the second direction is represented by Z1, and the third direction is represented by Z2.

[0167] That is, the multiple rows of matrix strips 11 are not arranged along a straight line. The second direction and the third direction constitute a two-dimensional coordinate system, and the second direction and the third direction can define the arrangement of the matrix strips 11.

[0168] It should be noted that the second direction can be a straight line or a curve; the third direction can be a straight line or a curve.

[0169] At least part of the matrix strips 11 are distributed on multiple trajectory lines, which means that all the matrix strips 11 can be distributed on multiple trajectory lines, or part of the matrix strips 11 can be distributed on multiple trajectory lines. For example, there can also be a matrix strip 11 located on the center line of the aerosol generating matrix segment, that is, the matrix strip 11 roughly coincides with or completely coincides with the center line of the aerosol generating matrix segment.

[0170] Each matrix strip 11 extends along the first direction or has an inclination angle with the first direction of not more than 10 degrees, which means that each matrix strip 11 extends completely along the first direction, or substantially along the first direction, or is bent at an angle of not more than 10 degrees.

[0171] For example, see Figure 11 The substrate strips 11 on a single trajectory are arranged linearly along the second direction, and the multiple trajectory lines are arranged linearly along the third direction, with the second and third directions intersecting. That is, the second and third directions are non-parallel straight lines. This results in the aerosol-generating substrate segment 10 having a quadrilateral cross-sectional shape.

[0172] For example, see Figures 1 to 5 The matrix strips 11 on a single trajectory line are roughly or completely arranged along the circumferential direction around the center of the aerosol generating matrix segment 10, and the multiple trajectory lines are roughly or completely arranged in concentric circles along the cross section perpendicular to the first direction.

[0173] The circumferential direction around the center of the aerosol-generating substrate segment 10 is equivalent to the second direction, and the radial direction of the aerosol-generating substrate segment 10 is equivalent to the third direction. That is, the plurality of substrate strips 11 may be arranged in a ring shape.

[0174] In some embodiments where the plurality of trajectory lines are arranged substantially or completely concentrically along a cross section perpendicular to the first direction, a substrate strip 11 may be located on the centerline of the aerosol-generating substrate segment 10, i.e., the substrate strip 11 substantially coincides with or completely coincides with the central axis of the aerosol-generating substrate segment 10. Of course, in other embodiments, no substrate strip 11 is provided on the centerline of the aerosol-generating substrate segment 10, which facilitates coordination with a central heating method.

[0175] For example, see Figure 2 、 Figure 4 and Figure 5 , the cross-sectional dimensions of each substrate strip 11 on a single trajectory line are the same. In a cross section perpendicular to the first direction, the cross-sectional dimensions of the substrate strips 11 on the outermost single trajectory line away from the center of the aerosol-generating substrate segment 10 are larger or smaller than the cross-sectional dimensions of the substrate strips 11 on the inner single trajectory line.

[0176] Here, the cross-sectional dimensions of the matrix strips 11 on a single track line are the same, and the densities of the matrix strips 11 on a single track line may be the same or different.

[0177] In some embodiments, see Figure 2 The cross-sectional size of the matrix strip 11 on the outermost trajectory line is the largest, that is, the cross-sectional size of the matrix strip 11 on the trajectory line farthest from the center of the aerosol generating matrix segment 10 is the largest. Except for the matrix strip 11 on the outermost trajectory line, the cross-sectional sizes of the matrix strips 11 on other trajectory lines can be the same or different.

[0178] The aerosol-generating matrix segment 10 of this embodiment is suitable for cooperation with the central heating method. In this way, the heating component of the central heating method can be closer to the inner matrix strip 11 with a smaller cross-sectional size, which can speed up the initial smoke output speed and increase the initial smoke volume, while the outer matrix strip 11 with a larger cross-sectional size is away from the heating component and can slowly and fully release the aerosol, thereby improving the problem that the effective substance is difficult to fully release during the heating process and the smoke volume and satisfaction in the middle and later stages of inhalation decay too quickly.

[0179] In other embodiments, please refer to Figure 4 and Figure 5 The cross-sectional size of the matrix strip 11 on the outermost trajectory line is the smallest, that is, the cross-sectional size of the matrix strip 11 on the trajectory line farthest from the center of the aerosol generating matrix segment 10 is the smallest. Except for the matrix strip 11 on the outermost trajectory line, the cross-sectional sizes of the matrix strips 11 on other trajectory lines can be the same or different.

[0180] The aerosol-generating matrix segment 10 of this embodiment is suitable for cooperation with the circumferential heating method. In this way, the heating component of the circumferential heating method can be closer to the matrix strip 11 with a smaller cross-sectional size on the outside, which can speed up the initial smoke output speed and increase the initial smoke volume. The matrix strip 11 with the largest cross-sectional size on the inside is away from the heating component and can slowly and fully release the aerosol, thereby improving the problem that the effective substance is difficult to fully release during the heating process and the smoke volume and satisfaction in the middle and later stages of inhalation decay too quickly.

[0181] For example, see Figure 1 and Figure 8In the cross section perpendicular to the first direction, the cross-sectional size of the matrix strip 11 on the innermost single trajectory line close to the center of the aerosol generating matrix segment 10 is larger or smaller than the cross-sectional size of the matrix strip 11 on the outer single trajectory line.

[0182] In some embodiments, see Figure 8 The cross-sectional size of the matrix strip 11 on the innermost trajectory line is the largest, that is, the cross-sectional size of the matrix strip 11 on the trajectory line closest to the center of the aerosol generating matrix segment 10 is the largest. Except for the matrix strip 11 on the innermost trajectory line, the cross-sectional sizes of the matrix strips 11 on other trajectory lines can be the same or different.

[0183] The aerosol-generating matrix segment 10 of this embodiment is suitable for cooperation with the circumferential heating method. In this way, the heating component of the circumferential heating method can be closer to the outermost matrix strip 11 with a smaller cross-sectional size, which can speed up the initial smoke output speed and increase the initial smoke volume, while the inner matrix strip 11 with a larger cross-sectional size is away from the heating component and can slowly and fully release the aerosol, thereby improving the problem of difficulty in fully releasing effective substances during the heating process.

[0184] In other embodiments, please refer to Figure 1 The cross-sectional size of the matrix strip 11 on the innermost trajectory line is the smallest, that is, the cross-sectional size of the matrix strip 11 on the trajectory line closest to the center of the aerosol generating matrix segment 10 is the smallest. Except for the matrix strip 11 on the innermost trajectory line, the cross-sectional sizes of the matrix strips 11 on other trajectory lines can be the same or different.

[0185] The aerosol generating substrate segment 10 of this embodiment is suitable for cooperation with a central heating method, so that the heating component of the central heating method can be closer to the inner substrate strip 11 with a smaller cross-sectional size.

[0186] Of course, in other implementations, see Figure 3 and Figure 10 The cross-sectional dimensions of the substrate strips 11 on a single trajectory are the same. As the aerosol generating substrate segment 10 moves radially outward, the cross-sectional dimensions of the substrate strips 11 on each trajectory gradually increase or decrease.

[0187] As the aerosol generating matrix segment 10 extends radially outward, the cross-sectional dimensions of the matrix strips 11 on each trajectory line gradually increase. The aerosol generating matrix segment 10 of this embodiment is suitable for cooperation with a central heating method. In this way, the heating component of the central heating method can be made closer to the matrix strips 11 with smaller cross-sectional dimensions on the inner side, thereby speeding up the smoke emission speed and increasing the initial smoke volume. The matrix strips 11 with larger cross-sectional dimensions on the outer side are away from the heating component and can slowly and fully release the aerosol, thereby improving the problem of difficulty in fully releasing effective substances during the heating process.

[0188] As the aerosol generating matrix segment 10 moves radially outward, the cross-sectional dimensions of the matrix strips 11 on each trajectory line gradually decrease. The aerosol generating matrix segment 10 of this embodiment is suitable for cooperation with the circumferential heating method. In this way, the heating component of the circumferential heating method can be closer to the matrix strips 11 with smaller cross-sectional dimensions on the outside, thereby speeding up the smoke emission speed and increasing the initial smoke volume. The matrix strips 11 with larger cross-sectional dimensions on the inside are away from the heating component and can slowly and fully release the aerosol, thereby improving the problem of difficulty in fully releasing effective substances during the heating process.

[0189] In some embodiments, see Figures 5 to 11 The density of each matrix strip 11 on a single track line is the same, and the density of the matrix strips 11 on at least some other track lines is different.

[0190] The density of the matrix strips 11 on at least part of the trajectory line is different, that is, the aerosol generating matrix segment 10 has both matrix strips 11 with relatively high density and matrix strips 11 with relatively low density. Therefore, in the initial stage of heating, the heat capacity of the matrix strips 11 with relatively low density is smaller than that of the matrix strips 11 with relatively high density. Compared with the matrix strips 11 with relatively high density, the matrix strips 11 with relatively low density can produce more sufficient aerosol faster in the front section of puffing, and in the middle and rear sections of puffing, although the aerosol produced by the matrix strips 11 with relatively low density will decay, the matrix strips 11 with relatively high density can produce more sufficient aerosol. Therefore, by coordinating the matrix strips 11 with different densities, the amount of aerosol released can be kept roughly consistent in the front, middle and rear sections of puffing, thereby improving the consistency of puffing and further improving the puffing experience.

[0191] In some embodiments, see Figure 5 and Figure 9 In a cross section perpendicular to the first direction, the density of the matrix strips 11 on the outermost single trajectory line away from the center of the aerosol generating matrix segment 10 is less than the density of the matrix strips 11 on at least one inner single trajectory line.

[0192] Here, the density of the matrix strips 11 on the outermost single trajectory line away from the center of the aerosol generating matrix segment 10 can be smaller than the density of the matrix strips 11 on some of the inner single trajectory lines, or can be smaller than the density of the matrix strips 11 on all of the inner single trajectory lines.

[0193] In an embodiment where the density of the matrix strips 11 on the outermost single trajectory line away from the center of the aerosol generating matrix segment 10 is less than the density of the matrix strips 11 on all the inner single trajectory lines, the density of the matrix strips 11 on the outermost trajectory line is the smallest, that is, the density of the matrix strips 11 on the trajectory line farthest from the center of the aerosol generating matrix segment 10 is the smallest, and the densities of the matrix strips 11 on other trajectory lines except the matrix strips 11 on the outermost trajectory line may be the same or different.

[0194] When the aerosol-generating matrix segments 10 of this embodiment are adapted for circumferential heating, the time required for heat transfer from the outside to the inside is shortened, thereby improving heat transfer efficiency. During the puffing process, the heating assembly first heats the low-density matrix strips 11 on the outermost trajectory. This allows the outermost low-density matrix strips 11 to generate sufficient aerosol in the early stages of the puff, while the inner high-density matrix strips 11 generate more sufficient aerosol in the middle and late stages of the puff, thereby fully releasing the active substance.

[0195] For other implementations, see Figure 1 and Figure 8 In a cross section perpendicular to the first direction, the density of the matrix strips 11 on the innermost single trajectory line close to the center of the aerosol generating matrix segment 10 is less than the density of the matrix strips 11 on at least one outer single trajectory line.

[0196] Here, the density of the matrix strips 11 on the innermost single trajectory line close to the center of the aerosol generating matrix segment 10 can be smaller than the density of the matrix strips 11 on some of the outer single trajectory lines, or can be smaller than the density of the matrix strips 11 on all of the outer single trajectory lines.

[0197] In an embodiment where the density of the matrix strips 11 on the innermost single trajectory line close to the center of the aerosol generating matrix segment 10 is less than the density of the matrix strips 11 on all the outer single trajectory lines, the density of the matrix strips 11 on the innermost trajectory line is the smallest, that is, the density of the matrix strips 11 on the trajectory line closest to the center of the aerosol generating matrix segment 10 is the smallest, and the densities of the matrix strips 11 on other trajectory lines except the matrix strips 11 on the innermost trajectory line may be the same or different.

[0198] When the aerosol-generating matrix segment 10 of this embodiment is adapted for central heating, the time required for heat conduction from the inside out is shortened, and the efficiency of infrared outward penetration is improved, thereby enhancing heat transfer and heating efficiency. During the puffing process, the heating component first heats the low-density matrix strips 11 on the outermost trajectory, so that the outermost low-density matrix strips 11 generate sufficient aerosol in the early stages of the puff, while the inner high-density matrix strips 11 generate more sufficient aerosol in the middle and late stages of the puff, thereby fully releasing the effective substance.

[0199] It should be noted that the above trajectory lines with the highest or lowest density are not limited to a single one, but can also be two or more consecutive ones, and are specifically designed according to the heating characteristics of the heating component.

[0200] In some embodiments, the density of each matrix strip 11 on a single trajectory line is the same, and the density of the matrix strips 11 on each trajectory line gradually increases or decreases as it moves radially outward from the aerosol generating matrix segment 10 .

[0201] That is, the density of the substrate strips 11 on different trajectory lines is different, and the farther away from the center of the aerosol generating substrate segment 10, the smaller or larger the density of the substrate strips 11.

[0202] Illustratively, in some embodiments, taking a plurality of trajectory lines arranged in a ring as an example, the density of each matrix strip 11 can gradually decrease from the matrix strip 11 on the first trajectory line close to the center of the aerosol generating matrix segment 10 to the matrix strip 11 on the last trajectory line away from the center of the aerosol generating matrix segment 10, that is, the density of the matrix strip 11 on the outermost single trajectory line of the aerosol generating matrix segment 10 in this embodiment is the smallest. Therefore, the aerosol generating matrix segment 10 of this embodiment is adapted to the circumferential heating method.

[0203] In other embodiments, the density of each matrix strip 11 can gradually increase from the matrix strip 11 on the first trajectory line close to the center of the aerosol generating matrix segment 10 to the matrix strip 11 on the last trajectory line away from the center of the aerosol generating matrix segment 10, that is, the density of the matrix strip 11 on the innermost single trajectory line of the aerosol generating matrix segment 10 in this embodiment is the smallest. Therefore, the aerosol generating matrix segment 10 of this embodiment is adapted to the central heating method.

[0204] Of course, in other embodiments, the matrix strips 11 may also be arranged in a matrix, and the density of the matrix strips 11 on each trajectory line may gradually decrease or increase from the center of the aerosol generating matrix segment 10 outward.

[0205] Of course, for the central heating method, the smaller the density of the matrix strips in the inner circle, the more conducive it is to the insertion of the aerosol generating matrix segment.

[0206] In some embodiments, the material composition of each matrix strip 11 on a single track line is the same, and the material composition of at least some matrix strips 11 on other track lines is different.

[0207] That is, the substrate strips 11 on a single track line can be made of the same material, and at least some of the substrate strips 11 on other track lines can be made of different materials.

[0208] For example, by setting the material composition of the matrix strips 11 on some other trajectory lines to be different, different functional requirements or different taste requirements can be met to improve the user experience. For example, the size of the aerosol volume, the speed of the smoke output, and the mixed flavor can be adjusted by different material compositions.

[0209] In some embodiments, the cross-sections of the matrix strips 11 on a single trajectory are the same, and the cross-sections of the matrix strips 11 on at least some other trajectory lines are different.

[0210] Here, the cross sections being the same or different means that the shapes and / or sizes of the cross sections are the same or different.

[0211] In this embodiment, the cross-section of each substrate strip 11 can be controlled based on the heat conduction and energy radiation characteristics of the heating assembly. For example, substrate strips 11 with smaller cross-sections are placed closer to the heating assembly, while substrate strips 11 with larger cross-sections are placed further away from the heating assembly. In this way, during the initial heating stage, the heat provided by the heating assembly is relatively small, but sufficient to ensure the heating and atomization of the substrate strips 11 with smaller cross-sections. Therefore, the substrate strips 11 with smaller cross-sections placed closer to the heating assembly can quickly release aerosol and increase the amount of smoke initially inhaled. However, as the heat provided by the heating assembly increases and heat conduction is sufficient, the substrate strips 11 with larger cross-sections placed further away from the heating assembly can fully release sufficient aerosol over a relatively long period of time, thereby improving the problem of uneven aerosol generation during the heating process.

[0212] In some embodiments, the matrix strips 11 include first matrix strips 111 and second matrix strips 112, wherein the density of the second matrix strips 112 is greater than that of the first matrix strips 111. Each matrix strip 11 on a single trajectory line is either a first matrix strip 111 or a second matrix strip 112. Radially outward from the aerosol generating matrix segment 10, the first matrix strips 111 and the second matrix strips 112 are arranged alternately.

[0213] Each matrix strip 11 on a single track line is either a first matrix strip 111 or a second matrix strip 112 . That is, each matrix strip 11 on the same track line is either a first matrix strip 111 or a second matrix strip 112 .

[0214] The alternating arrangement of the first matrix strips 111 and the second matrix strips 112 means that a single track line composed of the first matrix strips 111 and a single track line composed of the second matrix strips 112 are alternately arranged.

[0215] By alternately arranging a single trajectory line composed of the first matrix strips 111 and a single trajectory line composed of the second matrix strips 112 so that the first matrix strips 111 and the second matrix strips 112 cooperate with each other, the amount of aerosol released can be kept roughly consistent in the front, middle and back sections of the puff, thereby improving the consistency of the puff and further improving the puffing experience.

[0216] In the above embodiments, the first matrix strip 111 and the second matrix strip 112 can be made of the same material or different materials. For example, the matrix strip 11 with a smaller cross-sectional size can be designed to contain a relatively higher content of aerosol generating agent, so as to maximize the amount of smoke per inhalation while ensuring consistency.

[0217] In one embodiment, please refer to Figures 16 and 17 The cooling section 21 may be provided with an air flow channel 21a. The aerosol-generating article 1 may further include a breathable membrane 24. The breathable membrane 24 may be provided on the cooling section 21, and at least one end of the air flow channel 21a that is close to the aerosol-generating substrate segment 10 may be covered with the breathable membrane 24. In other words, the breathable membrane 24 may be provided only on the end of the air flow channel 21a that is close to the aerosol-generating substrate segment 10, or may be provided on opposite ends of the air flow channel 21a.

[0218] The breathable membrane 24 is a membrane through which air can pass. That is, the aerosol generated by the aerosol-generating substrate segment 10 can pass through the breathable membrane 24 into the air flow channel 21 a and be cooled in the air flow channel 21 a.

[0219] For example, the breathable membrane 24 may be cigarette paper, non-woven fabric, high molecular polymer, etc., which have good breathability.

[0220] For example, the air permeability of the breathable membrane 24 may be greater than or equal to 500 CU (CU is cm3 / (min*cm

[0221] *kpa)). Preferably, the air permeability of the breathable membrane 24 is greater than or equal to 1000 CU.

[0222] The breathable membrane 24 covering one end of the air flow channel 21a close to the aerosol generating matrix segment 10 can block the matrix strip 11 to prevent the matrix strip 11 from entering the air flow channel 21a in an accidental situation (for example, the central heating heating element pushes the matrix strip 11 into the air flow channel 21a when inserted). In this way, it can prevent the matrix strip 11 from entering the air flow channel 21a, resulting in a reduction in the number of matrix strips 11 that can be heated, thereby affecting the heating effect, and can also prevent the matrix strip 11 from blocking the air flow channel 21a and affecting the inhalation resistance.

[0223] In addition, the purpose of covering the air permeable membranes 24 at opposite ends of the air flow channel 21 a is to avoid distinguishing the assembly direction of the cooling section 21 during the assembly of the aerosol generating product 1, thereby improving the convenience of assembly.

[0224] In other embodiments, the breathable membrane 24 may not be set on the cooling section 21. For example, the breathable membrane 24 may cover one end of the aerosol generating matrix segment 10 close to the functional segment 20 or be set at both ends of the aerosol generating matrix segment 10.

[0225] In other embodiments, the cooling section 21 may also adopt other structural forms as long as it can achieve the cooling effect.

[0226] In one embodiment, please refer to Figure 17 The filter section 22 may be provided with a suction channel 22a to adjust the suction resistance.

[0227] In one embodiment, please refer to Figures 16 and 17 The functional section 20 may also be provided with a flavoring section 23, which is provided between the cooling section 21 and the filtering section 22 to compensate for the smoke flavor and enhance the smoking taste.

[0228] The structural form of the fragrance section 23 is not limited. For example, the fragrance section 23 can be provided with fiber cotton 231 that has been treated with fragrance, or the fragrance section 23 can be provided with fiber cotton 231 and popping beads 232. The fiber cotton 231 can be fiber cotton 231 that has been treated with fragrance, or it can be fiber cotton 231 that has not been treated with fragrance, and the popping beads 232 are arranged in the fiber cotton 231.

[0229] In other embodiments, the functional section 20 may not be provided with the flavoring section 23 .

[0230] For some examples, see Figure 18 and Figure 19 The aerosol-generating article 1 further includes a plug section 50, which is disposed at the end of the aerosol-generating matrix section 10 distal from the functional section 20. On the one hand, the plug section 50 heats the aerosol-generating matrix section 10, resulting in a relatively stable temperature field and good thermal efficiency. On the other hand, the plug section 50 can, to a certain extent, prevent the aerosol-generating matrix section 10 from falling after inhalation. The plug section 50 can have a porous structure or have an airway connecting the outside world and the aerosol-generating matrix section 10.

[0231] For example, in one embodiment, please refer to Figure 18 and Figure 19 The outer wrapping layer 30 can be wrapped around the outer periphery of the plug section 50.

[0232] For some examples, see Figure 18 and Figure 19 The plug section 50 is a hollow tube structure. This design can buffer the hot and cold airflows, reducing the strong convection of the hot and cold airflows, thereby reducing the condensation of smoke in the heating element or heating cavity, and greatly reducing the degree of dirt in the heating element and heating cavity.

[0233] For some examples, see Figure 19 The plug section 50 is a hollow tube structure, and a breathable membrane 60 is provided at one end of the plug section 50 away from the aerosol-generating matrix section 10. The membrane 60 has both breathability and barrier functions. The membrane 60 not only adjusts the draw resistance but also prevents the matrix strip 11 from falling through the central channel of the plug section 50.

[0234] In some embodiments, an insertion channel formed by the matrix strips 11 is provided at the center of the aerosol generating matrix segment 10. For example, the heating assembly can extend into the insertion channel. In other words, a central heating method can be employed. An insertion channel adapted to the size of the heating assembly can be reserved to reduce friction between the heating assembly and the matrix strips 11, thereby lowering the risk of the heating assembly pushing the matrix strips 11 into the functional segment 20.

[0235] In some embodiments, the aerosol-generating article may lack a functional segment. That is, the aerosol-generating substrate segment alone may constitute the aerosol-generating article for use in specialized aerosol-generating devices. For example, the aerosol-generating device includes a nozzle and a cooling component. The nozzle and cooling component may be reusable or disposable, and only the aerosol-generating substrate segment needs to be inserted into or removed from the heating space. The substrate strip may be any of the substrate strips and assembly structures described in the aforementioned embodiments, and will not be described in detail here.

[0236] In the above embodiments, the aerosol generating substrate segment may be cylindrical, sheet-shaped, square, etc., and may be adapted according to the characteristics of the heating component and the aerosol generating device.

[0237] Eight specific embodiments are briefly introduced below with reference to the accompanying drawings.

[0238] First embodiment

[0239] See also Figure 1 In this embodiment, the aerosol-generating matrix segment 10 includes at least two matrix strips 11 arranged in parallel, and the matrix strips 11 include first matrix strips 111 and second matrix strips 112. The density and cross-sectional dimensions of the second matrix strips 112 are greater than the density and cross-sectional dimensions of the first matrix strips 111. All second matrix strips 112 surround the outer peripheral side of all first matrix strips 111. The number ratio of the first matrix strips 111 to the second matrix strips 112 in the aerosol-generating matrix segment 10 is any one of 1:10-20:1.

[0240] All the matrix strips 11 are distributed on multiple trajectory lines. The matrix strips 11 on a single trajectory line are arranged along the circumferential direction around the center of the aerosol generating matrix segment 10. The multiple trajectory lines are arranged in concentric circles along the radial direction of the aerosol generating matrix segment 10.

[0241] When the aerosol-generating matrix segment 10 of this embodiment is adapted to the central heating method, the time required for heat to be conducted from the inside to the outside is shorter, thereby improving the heat transfer efficiency. During the puffing process, the heating component first heats the innermost low-density first matrix strip 111, and smoke is quickly discharged, so that the inner low-density first matrix strip 111 produces sufficient aerosol in the early stage of the puffing, and the outer high-density second matrix strip 112 produces a relatively sufficient aerosol in the middle and late stages of the puffing, and the effective substance is fully released. Taking full advantage of the advantages of the low-density and high-low-density matrix strips 11 while avoiding their disadvantages is conducive to the consistency of aerosol generation. In addition, the cross-sectional size of the first matrix strip 111 is relatively small, and the volume proportion of the first matrix strip 111 in the aerosol-generating matrix segment 10 can be controlled as small as possible, thereby increasing the volume proportion of the high-density second matrix strip 112 as much as possible, thereby increasing the overall content of effective substances in the aerosol-generating matrix segment 10.

[0242] Second embodiment

[0243] In this embodiment, the aerosol-generating matrix segment 10 includes at least two matrix strips 11 arranged in parallel, and all the matrix strips 11 are distributed on multiple trajectory lines. The matrix strips 11 on a single trajectory line are arranged along the circumferential direction around the center of the aerosol-generating matrix segment 10, and the multiple trajectory lines are arranged in concentric circles along the radial direction of the aerosol-generating matrix segment 10.

[0244] For example, see Figure 2 Along the radial direction of the aerosol generating substrate segment 10, the cross-sectional size of the substrate strips 11 on the outermost single trajectory line away from the center of the aerosol generating substrate segment 10 is larger than the cross-sectional size of the substrate strips 11 on the inner single trajectory line.

[0245] For example, see Figure 4 and Figure 5 Along the radial direction of the aerosol-generating matrix segment 10, the cross-sectional dimensions of the matrix strips 11 on the outermost single trajectory, away from the center of the aerosol-generating matrix segment 10, are smaller than the cross-sectional dimensions of the matrix strips 11 on the inner single trajectory. The diameter of the inner matrix strips is larger than that of the outer matrix strips, and the outer matrix segment has a greater number of pores. This design is more conducive to infrared heating, more conducive to the penetration of infrared light into the interior, and improves the consistency of heating.

[0246] For example, see Figure 3, along the radial outward direction of the aerosol generating substrate segment 10, the cross-sectional size of the substrate strips 11 on each trajectory line gradually increases.

[0247] The aerosol generating matrix segment 10 includes both matrix strips 11 with relatively large cross-sectional dimensions and matrix strips 11 with relatively small cross-sectional dimensions. Therefore, by combining matrix strips 11 with different cross-sectional dimensions, the filling rate, density and porosity of the aerosol generating matrix segment 10 can be controlled and set, which is conducive to matching different heating components and heating methods.

[0248] The second matrix strips 112 with larger cross-sectional dimensions carry relatively more effective substances, but have a relatively larger heat capacity, while the first matrix strips 111 with smaller cross-sectional dimensions carry relatively less effective substances, but have a relatively smaller heat capacity. Therefore, the second matrix strips 112 with larger cross-sectional dimensions, away from the heating component, can fully release aerosols for a relatively long time, while the first matrix strips 111 with smaller cross-sectional dimensions, close to the heating component, can speed up the smoke output speed and increase the initial smoke volume, thereby improving the problem of difficulty in fully releasing effective substances during the heating process. Therefore, by coordinating the first matrix strips 111 and the second matrix strips 112, and depending on the arrangement of the first matrix strips 111 and the second matrix strips 112, different heating components and heating methods can be matched to improve the heating efficiency of the heating component.

[0249] Third embodiment

[0250] In this embodiment, the aerosol-generating matrix segment 10 includes at least two matrix strips 11 arranged in parallel, and the matrix strips 11 include a first matrix strip 111 and a second matrix strip 112. The density and cross-sectional dimensions of the second matrix strip 112 are both greater than the density and cross-sectional dimensions of the first matrix strip 111. The number ratio of the first matrix strips 111 to the second matrix strips 112 in the aerosol-generating matrix segment 10 is any one of 1:10-20:1.

[0251] All the matrix strips 11 are distributed on multiple trajectory lines. The matrix strips 11 on a single trajectory line are arranged along the circumferential direction around the center of the aerosol generating matrix segment 10 . The multiple trajectory lines are arranged in concentric circles along the radial direction of the aerosol generating matrix segment 10 .

[0252] For example, see Figure 5 Along the radial direction of the aerosol generating matrix segment 10 , the matrix strips 11 on the outermost single trajectory line away from the center of the aerosol generating matrix segment 10 are first matrix strips 111 , and the matrix strips 11 on the inner single trajectory line are second matrix strips 112 .

[0253] When the aerosol-generating matrix segment 10 of this embodiment is adapted for circumferential heating, the time required for heat transfer from the outside to the inside is shorter. The outer first matrix strips 111 have a smaller heat capacity, making it easier to quickly produce smoke and increase the amount of smoke in the first puff, thereby improving heat transfer efficiency. During the puffing process, the heating component first heats the low-density first matrix strips 111 on the outermost trajectory. This allows the outermost low-density first matrix strips 111 to produce sufficient aerosol in the early stages of the puff, while the inner high-density second matrix strips 112 produce more aerosol in the middle and late stages of the puff, effectively releasing the active substance. Furthermore, the cross-sectional dimensions of the first matrix strips 111 are relatively small, allowing the volume share of the first matrix strips 111 in the aerosol-generating matrix segment 10 to be kept as small as possible, thereby maximizing the volume share of the high-density second matrix strips 112 and thereby increasing the overall active substance content in the aerosol-generating matrix segment 10.

[0254] Fourth embodiment

[0255] See also Figure 6 In this embodiment, the aerosol-generating matrix segment 10 includes at least two matrix strips 11 arranged in parallel, and the matrix strips 11 include a first matrix strip 111 and a second matrix strip 112. The density and cross-sectional size of the second matrix strip 112 are both greater than the density and cross-sectional size of the first matrix strip 111. The two are randomly or uniformly distributed in the aerosol-generating matrix segment 10, and the number ratio of the first matrix strip 111 to the second matrix strip 112 in the aerosol-generating matrix segment 10 is any one of 1:10-20:1.

[0256] The aerosol-generating matrix segment 10 of this embodiment is adapted for either a circumferential heating method or a central heating method. The aerosol-generating matrix segment 10 includes both matrix strips 11 with relatively high density and matrix strips 11 with relatively low density. Therefore, in the initial stage of heating, the matrix strips 11 with relatively low density are preferentially heated to generate aerosols. Compared with the matrix strips 11 with relatively high density, the matrix strips 11 with relatively low density can generate more sufficient aerosols in the front section of the puff. In the middle and back sections of the puff, although the aerosols generated by the matrix strips 11 with relatively low density will attenuate, the matrix strips 11 with relatively high density can generate more sufficient aerosols. Therefore, by combining matrix strips 11 with different densities, the amount of aerosol released can be kept roughly consistent in the front, middle and back sections of the puff, thereby improving the consistency of the puff and, in turn, improving the puffing experience.

[0326] Data Analysis: The average puff volume (i.e., aerosol) produced by the aerosol-generating matrix segment 10 during the heating process was 3.59 mg / puff, with an RSD (relative standard deviation) of 38.2%. During the heating process, the aerosol volume produced during the initial puff, as well as the puff-by-puff release of active substances such as aerosol generating agents and nicotine in the smoke, was sufficient, but a significant decrease occurred during the latter stages of the puff. This is primarily due to the low density of the aerosol-generating matrix segment 10, resulting in a low and limited effective load, which results in poor consistency between the initial and final puffs.

[0334] Data Analysis: The average puff volume (i.e., aerosol) produced by the aerosol-generating matrix segment 10 during the heating process was 3.49 mg / puff, with an RSD (relative standard deviation) of 29.4%. During the heating process, the amount of smoke produced during the initial puff, as well as the puff-by-puff release of active substances such as aerosol generating agents and nicotine in the smoke, was relatively low, but showed significant increases in the middle and later stages. This is primarily due to the matrix's high density and high payload, which requires the matrix to absorb sufficient heat in the early stages of the puff to generate a stable aerosol, resulting in a poorer puff experience.

[0342]

[0343] Data analysis: The average value of the amount of smoke (i.e., aerosol) generated by the aerosol generating matrix segment 10 during the heating process is 3.54 mg / puff, and the RSD (relative standard deviation) of the smoke volume per puff is 23.8%. Under the same test conditions, the aerosol generating matrix segment 10 of the comparative test example 3 before and after puffing generates 25.9% less aerosol than the aerosol generating matrix segment 10 of the test example 1 of the present application. The main reason is that the thin-sheet aerosol generating matrix segment 10 and the aerosol generating matrix segment 10 of the test example of the present application have obvious differences in morphology, and the shape and distribution of the voids are quite different. In addition, the density of the thin-sheet aerosol generating matrix segment 10 is lower, and the effective load is lower, which leads to limited aerosol generated during the puffing process.
