Description

Technical Field

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

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

[0003] In related technologies, the effective heating length of the substrate segment is relatively short due to its own structure, which makes it difficult for the substrate segment to achieve long-term heating. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide a matrix segment, an aerosol generating article, and an aerosol generating apparatus that can achieve long-term heating.

[0005] To achieve the above objectives, one embodiment of this application provides a matrix segment, which is strip-shaped and extends spirally to form a spiral structure with a hollow space.

[0006] In one embodiment, the matrix segment is a constant-diameter spiral structure or a variable-diameter spiral structure.

[0007] In one embodiment, the outer diameter of the helix of the matrix segment is 10 mm to 100 mm; and / or,

[0008] The cross-sectional area of ​​the matrix segment is 0.19 mm² to 314 mm²; and / or,

[0009] The free length of the matrix segment is 30mm to 320mm; and / or,

[0010] The pitch of the matrix segment is 5mm to 50mm; and / or,

[0011] The number of spiral turns in the matrix segment is 3 to 15; and / or,

[0012] The aspect ratio of the matrix segment is 15 to 25.

[0013] Another embodiment of this application provides an aerosol-generating article, the aerosol-generating article comprising the matrix segment described above.

[0014] Another embodiment of this application provides an aerosol generating apparatus for heating the aerosol generating product described above. The aerosol generating apparatus includes a heating component for extending into the hollow space of the matrix segment. The heating component includes multiple independently temperature-controllable heating units, each of which is arranged sequentially along a first direction to heat the matrix segment in sections along the axial direction of the matrix segment.

[0015] In one embodiment, the number of heating units is at least three; and / or, the heating units are in the form of plates or columns.

[0016] In one embodiment, each of the heating units is spaced apart from the substrate segment.

[0017] In one embodiment, during the heating of the aerosol-generated product by the aerosol generating apparatus, the temperature difference between one portion of the heating units and another portion of the heating units is greater than 150°C; and / or,

[0018] During the heating process of the aerosol-generating device on the aerosol-generated product, the temperature of a portion of the heating units is less than 50% of the temperature of the other portion of the heating units.

[0019] In one embodiment, the heating assembly further includes a heat insulation structure disposed between at least partially adjacent two heating units.

[0020] In one embodiment, the thermal insulation structure includes at least one of a thermal insulation pad, a thermal insulation coating, and a thermal insulation cavity.

[0021] This application provides a matrix segment, an aerosol generating product, and an aerosol generating device. The matrix segment is a spiral structure with a hollow space. For a spiral matrix segment, the effective heating length of the matrix segment is the length of the matrix segment along the spiral extension direction. Therefore, using a spiral matrix segment can significantly increase the effective heating length of the matrix segment, thereby enabling the matrix segment to achieve long-term heating.

[0031] One embodiment of this application provides an aerosol-generating article 10, please refer to [link / reference]. Figures 1 to 3 The aerosol-generated article 10 includes a matrix segment 11.

[0032] The aerosol generating product 10 can be used in conjunction with an aerosol generating device having a heating component. Specifically, the heating component heats and atomizes the matrix section 11 to generate an aerosol for users to inhale or for use in medicine, beauty, etc.

[0035] The skeleton component provides a supporting skeleton for the prepared matrix segment 11, which is beneficial to the shaping of the matrix segment 11. In addition, it can also provide attachment sites for other components, such as fragrance components, thereby improving the aroma quality of the aerosol-generated product 10.

[0036] In some embodiments, the skeletal components may be one or more combinations of chemicals such as cellulose, hemicellulose and lignin, or one or more combinations of pulverized plants such as tobacco raw materials, tobacco fragments, tobacco stems, tobacco dust, aromatic plants, etc., after being crushed, or a combination of chemicals and pulverized plants.

[0040] The flavoring components provide characteristic aromas to the aerosol-generating product 10, such as hay, roasted sweetness, and nicotine, thereby enhancing the user's smoking experience.

[0041] In some embodiments, the fragrance component may be a solid or liquid substance, such as one or more combinations of tobacco, aromatic plant extracts, extracts, essential oils, absolutes, etc. The fragrance component may also be a monomeric fragrance substance, such as one or more combinations of megastigmatrienone, neophytadiene, geraniol, nerol, raspberry ketone, etc.

[0042] In some embodiments, the content of the flavoring component may be 0.1% to 8% (inclusive) based on the total mass of the composition. For example, the content of the flavoring component may be 0.1%, 0.5%, 1%, 3%, 5%, 8%, etc.

[0043] The adhesive component comes into close contact with the material interfaces of each component in the matrix segment 11 through wetting, generating intermolecular attraction, thereby playing the role of bonding the powder, liquid and other components.

[0044] In some embodiments, the adhesive component may be one or more combinations of tamarind polysaccharide, guar gum, modified cellulose (such as carboxymethyl cellulose), etc.

[0045] In some embodiments, the content of the adhesive component may be 1% to 10% (including endpoint values) based on the total mass of the composition. For example, the content of the adhesive component may be 1%, 2%, 3%, 5%, 8%, 10%, etc.

[0046] In addition, other functional components can be added as needed. These other functional components include, but are not limited to, additives that enhance the suction experience, such as organic substances, inorganic substances, and organic-inorganic complexes.

[0047] Please continue reading. Figure 2 and Figure 3 In this embodiment, the matrix segment 11 is strip-shaped and extends spirally to form a spiral structure with a hollow space 11a. That is, the matrix segment 11 is a spiral structure formed by rotating the strip-shaped matrix segment 11 around a virtual axis Z.

[0048] The shape of the cross section of the matrix segment 11 is not limited. For example, the shape of the cross section of the matrix segment 11 can be circular, polygonal (including but not limited to triangle, square, rhombus, etc.), elliptical, racetrack-shaped, irregular, etc., where irregular refers to other symmetrical or asymmetrical shapes other than those listed above.

[0049] The matrix segment 11 preferably adopts an integral structure. The integral matrix segment 11 can be manufactured by integral molding processing methods, such as extrusion, rolling, and die casting.

[0050] In other embodiments, the matrix segment 11 can also be made by processing methods such as slurry method, sheet method, roller pressing method, and natural tobacco leaf shredding, and there is no limitation here.

[0051] Figure 2 and Figure 3 The matrix segment 11 shown is a constant diameter spiral structure. A constant diameter spiral structure refers to a spiral structure in which the outer diameter D of the spiral of the matrix segment 11 remains unchanged. The outer diameter D of the spiral refers to the maximum diameter of the matrix segment 11 when it rotates around the virtual axis Z.

[0052] In other embodiments, the matrix segment 11 may also be a variable diameter helical structure. A variable diameter helical structure refers to a helical structure in which the outer diameter D of the helix of the matrix segment 11 varies. For example, the variable diameter helical structure may be a conical helical structure, a stepped helical structure, etc.

[0053] The outer diameter D of the helix of the matrix segment 11 can be designed as needed. Preferably, the outer diameter D of the helix of the matrix segment 11 is 10mm to 100mm (including the endpoint value). For example, the outer diameter D of the helix of the matrix segment 11 can be 10mm, 30mm, 50mm, 80mm, 100mm, etc.

[0054] When the matrix segment 11 is a variable diameter helical structure, the outer diameter D of the helix of the matrix segment 11 refers to the maximum outer diameter D of the helix.

[0055] The cross-sectional area of ​​the matrix segment 11 can be designed as needed. Preferably, the cross-sectional area of ​​the matrix segment 11 can be 0.19 mm² to 314 mm² (including the endpoints). For example, the cross-sectional area of ​​the matrix segment 11 can be 0.19 mm². 2 0.5mm 2 5mm 2 20mm 2 50mm 2 100mm 2 150mm 2 200mm 2 250mm², 300mm², 314mm², etc.

[0056] The free length L of matrix segment 11 can be designed as needed; please refer to [reference needed]. Figure 3 The free length L refers to the total length of the matrix segment 11 in its natural state without being subjected to external force, along the extension direction of the axis Z (hereinafter referred to as the axial direction). Preferably, the free length L of the matrix segment 11 can be 30mm to 320mm (including the endpoint value). For example, the free length L of the matrix segment 11 can be 30mm, 50mm, 80mm, 100mm, 150mm, 200mm, 250mm, 300mm, 320mm, etc.

[0057] The pitch P of the matrix segment 11 can be designed as needed; please refer to [reference needed]. Figure 3 Pitch P refers to the axial distance between the centers of the cross sections of two adjacent rings in the spiral structure formed by the matrix segment 11. Preferably, the pitch P of the matrix segment 11 can be 5mm to 50mm (including the endpoint value). For example, the pitch P of the matrix segment 11 can be 5mm, 10mm, 15mm, 20mm, 30mm, 40mm, 50mm, etc.

[0058] The number of spiral turns of the matrix segment 11 can be designed as needed. The number of spiral turns refers to the number of spiral structures formed by the matrix segment 11. Preferably, the number of spiral turns of the matrix segment 11 can be 3 to 15 (including the endpoint value). For example, the number of spiral turns of the matrix segment 11 can be 3, 5, 10, 15, etc.

[0059] The aspect ratio of the matrix segment 11 can be designed as needed. The aspect ratio refers to the ratio of the outer diameter D of the helix of the matrix segment 11 to the cross-sectional dimension of the matrix segment 11, i.e., outer diameter D / cross-sectional dimension. Wherein, if the cross-sectional shape of the matrix segment 11 is circular, the cross-sectional dimension is the diameter of the cross-section; if the cross-sectional shape of the matrix segment 11 is non-circular, the cross-sectional dimension is the width of the cross-section or a feature dimension equivalent to the width. Preferably, the aspect ratio of the matrix segment 11 can be 15 to 25, for example, the aspect ratio of the matrix segment 11 can be 15, 20, 25, etc.

[0060] In addition to the matrix segment 11, the aerosol-generating article 10 may also include a functional segment. The matrix segment 11 has two opposite ends along its axial direction: a proximal end and a distal end. The proximal end is the end closest to the user's mouth during aspiration, and the distal end is the end furthest from the user's mouth during aspiration. The functional segment may be located at the proximal end and / or the distal end of the matrix segment 11 according to its function.

[0061] In some embodiments, the functional segment may include a filter segment disposed near the lip end of the matrix segment 11. The filter segment is used to contact the user's mouth during aspiration to filter the aerosol.

[0062] The materials used in the filter section include, but are not limited to, one or more combinations of PE (polyethylene), PLA (polylactic acid), PBAT (butylene adipate-co-terephthalate), PP (polypropylene), cellulose acetate, and propylene fiber materials.

[0063] In other embodiments, the functional section may not have a filter section. For example, the aerosol generating device 20 may be equipped with a nozzle that can be reused or used only once. The nozzle is used in conjunction with the aerosol generating product 10 without a filter section to replace the filter section.

[0064] In some embodiments, the functional segment may include a cooling segment disposed near the lip end of the matrix segment 11. The aerosol is cooled as it passes through the cooling segment.

[0065] For the aerosol generating product 10 with a filter section, the filter section is located on the side of the cooling section away from the matrix section 11.

[0066] In some other embodiments, a cooling section may not be included.

[0067] In some embodiments, the functional segment may further include a support segment disposed near the lip end of the matrix segment 11.

[0068] The support section is mainly used to provide support for the functional section in order to improve the structural strength of the functional section, especially the structural strength at high temperatures.

[0069] For the aerosol generating article 10 with a filter section, the filter section is located on the side of the support section away from the matrix section 11.

[0070] For the aerosol generating product 10 with a cooling section, the cooling section and the support section are located between the matrix section 11 and the filter section. The support section can be located on the side of the cooling section away from the matrix section 11, or it can be located between the cooling section and the matrix section 11.

[0071] In other embodiments, the support segment may not be provided.

[0072] In some embodiments, the functional segment may include a pre-plug segment disposed at the distal lip of the matrix segment 11. The pre-plug segment can prevent the matrix segment 11 from shrinking and falling off after heating and from adsorbing backflowing aerosols.

[0073] In some other embodiments, the front plug section may be omitted.

[0074] In other embodiments, functional sections may not be provided.

[0075] In some embodiments, the aerosol generating article 10 may further include an outer coating layer that wraps around the outer periphery of the matrix segment 11. For the aerosol generating article 10 having functional segments, the outer coating layer may also wrap around the outer periphery of the functional segments.

[0076] The outer wrapping layer is made of one or more of the following materials, including but not limited to fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE, PBAT, and silicone rubber.

[0077] In other embodiments, the outer wrapping layer may not be provided.

[0078] In related technologies, the matrix segment is generally cylindrical, and the effective heating length of the cylindrical matrix segment is its axial length. Since the matrix segment is heated within an aerosol generating device, and the space within the aerosol generating device to accommodate the matrix segment is limited, the effective heating length of the cylindrical matrix segment is restricted, making it difficult to achieve long-term heating of the matrix segment.

[0079] In this embodiment, the substrate segment 11 is a spiral structure. For the spiral structure substrate segment 11, the effective heating length of the substrate segment 11 is the length of the substrate segment 11 along the spiral extension direction, rather than the length of the spiral structure along the axial direction (i.e., not the free length L of the spiral structure). Therefore, compared with the columnar substrate segment 11, the use of a spiral structure substrate segment 11 can significantly increase the effective heating length of the substrate segment 11, thereby enabling the substrate segment 11 to achieve long-term heating.

[0080] Another embodiment of this application provides an aerosol generating apparatus 20, which can be used to heat the aerosol generating article 10 provided in any embodiment of this application.

[0081] Please see Figure 1 , Figures 4 to 6 The aerosol generating apparatus 20 of this application embodiment includes a heating component 21, which heats the matrix segment 11 by extending into the hollow space 11a of the matrix segment 11.

[0082] Specifically, the aerosol generating device 20 has a housing 22, and a heating component 21 is disposed inside the housing 22. The portion of the aerosol generating article 10 having a matrix section 11 is inserted into the housing 22 so that the heating component 21 can extend into the hollow space 11a of the matrix section 11.

[0083] Please continue reading. Figures 4 to 6 The heating assembly 21 includes multiple independently temperature-controlled heating units 211, which are arranged sequentially along the first direction to heat the substrate segment 11 in sections along the axial direction of the substrate segment 11.

[0084] The number of heating units 211 can be two or more. More preferably, the number of heating units 211 can be at least three.

[0085] For example, Figures 4 to 6 The heating assembly 21 shown has four heating units 211.

[0086] Independent temperature control means that the heating temperature of each heating unit 211 can be controlled independently, without being affected by other heating units 211.

[0087] Each heating unit 211 can be an independent heating element, or it can be multiple independently temperature-controlled heating zones set in the same heating element.

[0088] The specific shape of the heating unit 211 is not limited; for example, the heating unit 211 can be in the form of a sheet or a column.

[0089] The first direction is the orientation in which each heating unit 211 is positioned within the housing 22. After the heating assembly 21 extends into the hollow space 11a of the matrix section 11, the first direction can be parallel to the axial direction of the matrix section 11 or inclined relative to the axial direction of the matrix section 11.

[0090] Please see Figures 4 to 6 After the heating component 21 extends into the hollow space 11a of the matrix segment 11, each heating unit 211 corresponds to a different part of the matrix segment 11 along the axial direction. Each heating unit 211 can heat the part of the matrix segment 11 along the axial direction individually, thereby realizing zoned heating.

[0091] To prevent the substrate segment 11 from scorching during the heating process, each heating unit 211 can be arranged at intervals with the substrate segment 11.

[0092] The aerosol generating device 20, in conjunction with the spiral matrix section 11, can significantly increase the total number of suction ports for the aerosol generating product 10, thereby reducing the cost of using the aerosol generating product 10.

[0093] In addition, since each heating unit 211 can be independently temperature controlled, the heating logic of the heating component 21 of the aerosol generating device 20 can be designed according to the actual suction requirements. For example, one part of the heating units 211 can be controlled to start heating in one time period and another part of the heating units 211 can be controlled to start heating in another time period. Alternatively, the heating temperature of one part of the heating units 211 can be controlled to be different from that of another part of the heating units 211 in the same time period. This allows for precise and selective heating of different parts of the matrix section 11 along the axial direction, thereby ensuring a better consistency in taste.

[0094] In some embodiments, during the heating of the aerosol-generated article 10 by the aerosol generating device 20, the temperature difference between one portion of the heating units 211 and another portion of the heating units 211 can be greater than 150°C. The heating unit 211 with the relatively lower temperature can be in a heating state or a non-heating state. A temperature difference greater than 150°C facilitates effective control of the aerosol release amount at different locations along the axial direction of the matrix section 11, thereby better ensuring consistent taste.

[0095] In some embodiments, during the heating of the aerosol-generated article 10 by the aerosol generating device 20, the temperature of one part of the heating unit 211 may be less than 50% of the temperature of another part of the heating unit 211. This arrangement can also facilitate the effective control of the aerosol release amount at different parts along the axial direction of the matrix section 11, thereby making it more conducive to ensuring the consistency of taste.

[0096] Furthermore, in some embodiments, the heating assembly 21 further includes a heat insulation structure disposed between at least two partially adjacent heating units 211. That is, a heat insulation structure can be disposed between any two adjacent heating units 211, or a heat insulation structure can be disposed between a portion of two adjacent heating units 211.

[0097] The specific structural form of the heat insulation structure is not limited. For example, the heat insulation structure may include at least one of the heat insulation pad, heat insulation coating and heat insulation cavity. That is, only one of the heat insulation pad, heat insulation coating and heat insulation cavity may be provided between two adjacent heating units 211, or any two of the heat insulation pad, heat insulation coating and heat insulation cavity may be provided, or heat insulation pad, heat insulation coating and heat insulation cavity may be provided at the same time.

[0098] Thermal insulation pads include, but are not limited to, ceramic fiber pads; thermal insulation coatings include, but are not limited to, aerogel coatings; and thermal insulation cavities include, but are not limited to, vacuum isolation cavities.

[0099] By setting up a heat insulation structure, the two adjacent heating units 211 can be better separated, thereby avoiding the two adjacent heating units 211 from affecting the temperature of adjacent areas during their respective heating processes. This makes it more conducive to the precise control of the heating temperature of different parts of the substrate segment 11 in the axial direction.

[0100] In some other embodiments, the heating component 21 may not have a heat insulation structure.

[0101] In addition, it should be noted that the aerosol generating article 10 of this application embodiment is not limited to being heated by the aerosol generating device 20 of this application embodiment. In other embodiments, the aerosol generating article 10 can also be heated by other aerosol generating devices.

[0102] Similarly, the aerosol generating apparatus 20 of this application embodiment is not limited to heating the aerosol generating article 10 of this application embodiment. In other embodiments, the aerosol generating apparatus 20 can also heat aerosol generating articles with other structural forms.
