Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and particularly relates to a consumable suitable for an aerosol delivery device and an aerosol supply system. Background Art

[0002] Consumables such as cigarettes and cigars generate smoke containing various harmful chemical substances such as carbon monoxide when burning tobacco, which will cause great harm to the health of users and people around them. Therefore, they are gradually replaced by heat-not-burn products. Heat-not-burn (HNB) products are a new type of relatively harm-reducing tobacco substitute. They heat non-combustible consumables through an aerosol delivery device, so that the consumables release the aerosol-forming materials they carry in a non-combusted state. The aerosol-forming materials are mixed with air to generate aerosols for users to inhale.

[0003] Aerosol delivery devices can be roughly divided into peripheral heating type devices and central heating type devices according to their different heating methods. Among them, the central heating type device has an extremely fast heating speed, is favored by more and more users, and has gradually become the mainstream heating device in the aerosol supply system.

[0004] Central heating type aerosol delivery devices often have a heater, such as a heating needle, provided at the central part inside. However, existing consumables are mostly solid structures and cannot be used in combination with central heating type aerosol delivery devices. If a conventional solid consumable is inserted into an aerosol delivery device for use, there is a large frictional force between the consumable and the heater when the solid consumable is inserted into the central heating type aerosol delivery device, which easily causes the matrix with aerosol-forming materials in the consumable to be pushed out by the heater, resulting in a decrease in the total amount of aerosols that the consumable can generate, that is, when the user inhales the consumable, the number of inhalations that can be made is reduced; moreover, the matrix around the heater is in close contact with the heater, and this closely contacted matrix is prone to carbonization due to excessive heating temperature during the heating process, and the carbonized substances are likely to remain on the heater, thereby affecting the heating effect and service life of the heater, and further affecting the use experience and cyclic service life of the aerosol supply system.

[0035] The embodiment of the present application provides a consumable 100, which is suitable for an aerosol delivery device. By providing heat through the aerosol delivery device, the aerosol-forming material loaded in the consumable 100 is mixed with air to generate aerosol for the user to inhale. Please refer to Figures 1 - 3 、 Figures 4 - 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 The consumable 100 includes an aerosol-forming matrix 10, 50, 60, 70, 80, 90 and a functional section. Among them, in some embodiments, the functional section may include at least one of a filter section 30 and a support section 20. In other embodiments, the functional section may further include a plug section 40.

[0036] The heating method of the aerosol delivery device is a central heating method. The central heater of the aerosol delivery device is inserted into the consumable 100 to bake and heat the consumable 100 from the inside to the outside. The heating method can be resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc.

[0037] The first embodiment Please refer to Figure 1 which is a schematic diagram of a consumable 100 suitable for an aerosol delivery device provided by the first embodiment of the present application.

[0038] A consumable 100 suitable for an aerosol delivery device provided by the first embodiment of the present application includes an aerosol generation matrix 10 and functional segments disposed at both ends of the aerosol generation matrix 10. In this embodiment, the structure of the aerosol generation matrix 10 is as shown in Figure 2 and Figure 3 shown.

[0039] As Figure 2 shown, the aerosol generation matrix 10 in the consumable 100 provided by the present application is a cylindrical structure with opposite first end 10A and second end 10B and a side surface. As shown in Figure 3 shown, a heating hole 12 penetrating from the first end 10A to the second end 10B is provided inside the aerosol generation matrix 10. When the consumable 100 is used with an aerosol delivery device, the heater of the aerosol delivery device will be inserted into the heating hole 12 to heat the aerosol generation matrix 10. Compared with the existing integrally formed solid consumable, the setting of the heating hole 12 in the aerosol generation matrix 10 of the consumable 100 provided by the present application can be adapted to the use of a center-heating type aerosol delivery device, and can better transfer the heating heat of the center-heating type aerosol delivery device evenly to the entire cylindrical structure of the aerosol generation matrix 10. Moreover, the heating hole 12 penetrates the entire aerosol generation matrix 10. When it is adapted to the center-heating type aerosol delivery device, the aerosol generation matrix 10 will not be extruded by the heater of the aerosol delivery device, so as not to affect the total amount of aerosol generated by the consumable 100 and improve the user experience.

[0040] The presence of the heating hole 12 in the consumable 100 can, when used with a center-heating type aerosol delivery device, place the center heater of the aerosol device in the heating hole 12 of the consumable 100. The heating hole 12 can accommodate the center heater of the aerosol device and also avoid overly close contact between the aerosol generation matrix 10 in the consumable 100 and the heater, thereby effectively preventing the situation where the aerosol generation matrix 10 adjacent to the periphery of the center heater is overheated and carbonized, that is, avoiding the attachment or residue of carbonized substances on the center heater, so as to improve the heating effect of the center heater and its service life, that is, to improve the service life of the aerosol delivery device using the consumable 100.

[0041] As Figure 3As shown, the aerosol generating substrate 10 includes a concave-convex film substrate group 11 arranged around a heating hole 12. The concave-convex film substrate group 11 contains an aerosol generating material, so that when the aerosol delivery device is used, the aerosol can be released by heating. In terms of mass fraction, the content of the aerosol generating material in the concave-convex film substrate group 11 is 15%-30%, that is, the mass of the aerosol generating material in the concave-convex film substrate group 11 accounts for 15%-30% of the mass of all materials in the entire concave-convex film substrate group 11, and the mass of all materials in the entire concave-convex film substrate group 11 is the overall mass of the concave-convex film substrate group 11 after molding. The concave-convex film substrate group 11 not only releases aerosol under the action of heating, but also has sufficient supporting effect, especially at high temperature, it can achieve the stability of the annular columnar structure of the aerosol generating substrate 10, ensuring that the aerosol generating material is released while maintaining the stability of the structure of the aerosol generating substrate 10 in the entire consumable 100, and will not collapse or deform. Furthermore, the embossed film substrate group 11 itself contains an aerosol generating material, for example, it is made of a tobacco sheet having an aerosol generating material or a non-tobacco sheet having an aerosol generating material. Therefore, there is no need to load the aerosol generating material on other media (such as paper or non-woven fabrics, etc.), thereby avoiding the introduction of other media to interfere with the aerosol aroma, thereby improving the purity and aroma of the aerosol generated by the consumable 100.

[0042] like Figure 2 and Figure 3 As shown, in the first embodiment of the present application, the concave-convex film substrate group 11 in the aerosol generating matrix 10 has a plurality of airflow channels 13, and the airflow channels 13 extend from the first end 10A to the second end 10B. The airflow channels 13 of the concave-convex film substrate group 11 can improve the air permeability of the consumable 100, facilitate the circulation of air during the central heating of the consumable 100, promote the uniform generation and emission of aerosol, and improve the user's smoking experience.

[0043] like Figure 2 and 3As shown, the corrugated film substrate group 11 includes at least one corrugated film layer 111. Moreover, at least one corrugated film layer 111 contains an aerosol generating material. In this embodiment, the corrugated film substrate group 11 includes a corrugated film layer 111. The wall thickness of the corrugated film layer 111 is H1, wherein 0.1mm≤H1≤0.8mm. Generally speaking, the wall thickness H1 of the same corrugated film layer 111 may be the same, and the wall thickness H1 of different corrugated film layers 111 may be the same or different. Furthermore, the corrugated film layer 111 may be in a sheet-like curved structure, arranged around the heating hole 12, and curled and folded outside the heating hole 12 to form a plurality of ridges and a plurality of valleys. The alternating arrangement of the multiple ridges and the multiple valleys of the concave-convex film layer 111 not only forms multiple airflow channels 13 on the concave-convex film substrate group 11, so that the airflow flows from the first end 10A of the aerosol substrate 10 to the second end 10B; and the alternating arrangement of the multiple ridges and the multiple valleys can also provide a good elasticity for the structure of the entire concave-convex film substrate group 11, and this good elasticity plays an important role in the rolling process of the concave-convex film layer 111 and even the entire aerosol generating substrate 10. The concave-convex film structure of the concave-convex film layer 111 can better meet the requirements of the rolling process, making the rolling process smoother, improving the production efficiency of the aerosol generating substrate 10 and the entire consumable 100 during processing, and at the same time, the concave-convex film structure of the concave-convex film layer 111 can also help to ensure the product quality of the aerosol generating substrate 10 after the rolling is completed, and reduce product defects caused by improper rolling.

[0044] In addition, at least one of the concave-convex film layers 111 contains an aerosol generating material, which means that it itself contains an aerosol generating material, for example, it is made of a tobacco sheet with an aerosol generating material or a non-tobacco sheet with an aerosol generating material. Therefore, there is no need to prepare the aerosol generating material into a film separately and load it on a carrier medium (such as paper or non-woven fabric, etc.), or to coat the aerosol generating material on the carrier medium, thereby simplifying the preparation process and avoiding the interference of the introduction of the carrier medium on the aerosol aroma, thereby improving the purity and aroma of the aerosol generated by the consumable; and, under normal circumstances, when the aerosol generating material is loaded or directly liquid-coated on the carrier medium after being formed into a film, the film-formed or coated aerosol generating material often affects the air permeability of the carrier medium, that is, it reduces the air permeability of the formed overall layer, hinders the flow of the aerosol and the efficiency of heat conduction to a certain extent, thereby increasing the inhalation resistance, reducing the aerosol generation rate, and affecting the user's smoking experience.

[0045] If the wall thickness H1 of the concavo-convex pattern film layer 111 is less than 0.1 mm, it is not conducive to its forming ridges and valleys arranged alternately at intervals. If the wall thickness H1 is greater than 0.8 mm, it is likely to break when curling to form multiple ridges and multiple valleys, which is also not conducive to its forming. By controlling the wall thickness H1 of the concavo-convex pattern film layer 111 to be between 0.1 mm and 0.8 mm, the forming quality of the concavo-convex pattern film layer 111 can be ensured. While ensuring that it has a concavo-convex pattern film structure, the stability of its fuming can also be guaranteed.

[0046] In this embodiment, the porosity of the concavo-convex pattern film layer 111 is 30%-70%. The porosity of the concavo-convex pattern film layer 111 refers to the percentage of the volume of all pores formed on the concavo-convex pattern film layer 111 in the total volume of the entire concavo-convex pattern film layer 111. If the porosity of the concavo-convex pattern film layer 111 is less than 30%, the overall structure of the concavo-convex pattern film layer 111 is too dense, which is not conducive to the flow of aerosol. If the porosity of the concavo-convex pattern film layer 111 is greater than 70%, the overall structure of the concavo-convex pattern film layer 111 is too loose, resulting in poor structural stability of the entire concavo-convex pattern film layer 111. It will also cause too little aerosol generating material that the concavo-convex pattern film layer 111 can carry, resulting in too little aerosol generated by the entire concavo-convex pattern film substrate group 11 and unable to meet the suction concentration requirements of the aerosol generating matrix 10.

[0047] The cross-sectional shape of the concavo-convex pattern film layer 111 in the concavo-convex pattern film substrate group 11 provided by the present application can be regular shapes such as U-shaped, V-shaped, UV-shaped, S-shaped, etc., or other regular or irregular shapes. Among them, the irregular shape refers to other symmetric or asymmetric shapes other than the shapes exemplified above. In this embodiment, the cross-sectional shape of the concavo-convex pattern film layer 111 is V-shaped and is evenly spaced along the circumferential direction. As Figure 3 shown, along the circumferential direction of the heating hole 12, the cross-sectional width W1 of the air flow channel 13 is 0.1 mm - 3 mm. That is, the distance between two adjacent ridges or the distance between two adjacent valleys of the concavo-convex pattern film layer 111 is 0.1 mm - 3 mm. Along the radial direction of the heating hole 12, the cross-sectional width W2 of the air flow channel 13 is 0.2 mm - 3.5 mm. That is, the maximum vertical distance from the ridge to the valley of the concavo-convex pattern film layer 111 is 0.2 mm - 3.5 mm.

[0048] The concavo-convex pattern film substrate group 11 of the aerosol generating matrix 10 provided by the present application further includes at least one of the inner layer 112 located at the innermost side and the outer layer 113 located at the outermost side of the concavo-convex pattern film substrate group 11.

[0049] In this embodiment, the corrugated film substrate group 11 includes an inner layer 112 located at the innermost side of the corrugated film substrate group 11 and an outer layer 113 located at the outermost side. The inner layer 112 is connected to the valleys of the corrugated film layer 111 and encloses with the valleys of the corrugated film layer 111 to form a plurality of air flow channels 13 arranged at equal intervals along the outer circumference of the inner layer 112. The outer layer 113 is connected to the ridges of the corrugated film layer 111 and encloses with the ridges of the corrugated film layer 111 to form a plurality of air flow channels 13 arranged at equal intervals along the inner circumference of the outer layer 113. A plurality of ridges of the corrugated film layer 111 are in contact with the outer layer 113, and a plurality of valleys are in contact with the inner layer 112.

[0050] In this embodiment, the corrugated film layer 111, the inner layer 112 and the outer layer 113 in the corrugated film substrate group 11 provided by the present application all contain an aerosol generating material. The aerosol generating material includes at least one of propylene glycol, glycerol, butylene glycol, pentylene glycol and ethylene glycol. The function of the corrugated film substrate group 11 containing the aerosol generating material is to be able to generate sufficient aerosol products for the user to inhale when heated.

[0051] Since most of the existing consumables have a hollow structure formed in one piece, the content of aerosol in the aerosol production matrix remains consistent from the inside to the outside or from top to bottom. When adapted to an aerosol delivery device, it is prone to problems such as uneven and unstable aerosol release during the user's suction process. That is, at the beginning of heating and suction, the aerosol content is too small, while at the end of suction, the aerosol content is too large, resulting in uneven aerosol concentration at the front and back stages of suction when the user uses the existing consumables, and a poor experience. In order to ensure that when the consumable 100 provided in this application is used in combination with an aerosol delivery device, during the entire heating process of the consumable 100, the concentration of aerosol generation remains uniform, it is necessary to adjust and control the proportion of aerosol generation materials between various parts of the corrugated film substrate group 11 to achieve approximately the same aerosol concentration at the beginning and end of heating. In the consumable 100 provided in this application, the content of aerosol generation materials in the inner layer 112 of the corrugated film substrate group 11 is greater than that in the corrugated film layer 111; the content of aerosol generation materials in the outer layer 113 is less than or equal to that in the corrugated film layer 111. The consumable 100 provided in this application is suitable for use in a central heating type aerosol delivery device. When the heater of the aerosol delivery device heats the aerosol production matrix 10 of the consumable 100, the preheating time of its central heater is short, and the heater quickly warms up, so that the innermost layer 112 closest to the center receives the heat conduction of the heater fastest. At this time, the content of aerosol generation materials in the inner layer 112 is greater than that in the corrugated film layer 111, so that the aerosol generation materials contained in the inner layer 112 are quickly released to meet the standard of aerosol concentration at the beginning of suction. As the heater continues to heat and bake, the aerosol generation materials on the inner layer 112 gradually decrease, and the aerosol concentration released by the inner layer 112 decreases. However, the heat of the inner layer 112 has been transferred to the corrugated film layer 111 and the outer layer 113. The aerosol released after heating by the corrugated film layer 111 and the outer layer 113 converges with the aerosol released by the inner layer 112 to form the aerosol concentration in the middle and later stages of suction to meet the standard of suction. The consumable 100 provided in this application adjusts the content of aerosol generation materials between different layers of the corrugated film substrate group 11 to achieve the regulation of the aerosol concentration released by the aerosol production matrix 10, so as to achieve the uniformity, stability and consistency of the concentration of aerosol material release during the entire heating and suction process, thereby improving the user's suction experience.

[0052] In the embossed film substrate group 11 provided by the present application, the embossed film layer 111, the inner layer 112 and the outer layer 113 all contain an aerosol generating material. By mass fraction, the content of the aerosol generating material in the embossed film layer 111 is 10%-25%, that is, in the embossed film layer 111, the mass of the aerosol generating material accounts for 10%-25% of the mass of all materials of the entire embossed film layer 111. Among them, the mass of all materials of the embossed film layer 111 is the overall mass of the embossed film layer 111 after molding.

[0053] Preferably, the content of the aerosol generating material in the inner layer 112 is 15%-35%, that is, in the inner layer 112, the mass of the aerosol generating material accounts for 15%-35% of the mass of all materials of the entire inner layer 112. Among them, the mass of all materials of the entire inner layer 112 is the overall mass of the inner layer 112 after molding.

[0054] Preferably, the content of the aerosol generating material in the outer layer 113 is less than or equal to 15%. In the outer layer 113, the mass of the aerosol generating material accounts for 15%-35% of the mass of all materials of the entire outer layer 113. The mass of all materials of the outer layer 113 is the overall mass of the outer layer 113 after molding.

[0055] In the concave-convex film substrate group 11, the hardness of the inner layer 112 is 50%-90%, that is, 50%≤hardness of the inner layer 112≤90%. The hardness of the inner layer 112 refers to the percentage of the diameter after compression to the diameter before compression of the rod-shaped structure formed by curling the inner layer 112 under a certain pressure within a certain period of time. The detection method of the inner layer 112 can be detected by the hardness determination method in the physical property determination of cigarettes and filter rods in GB / T 22838.6-2024. A pre-pressure (for example, 0.1±0.02N) is applied to the sample at a certain pressure rate (for example, not more than 3.0mm / s), and the pre-pressure is applied for a specific time (for example, 10±1s). The diameter of the sample after compression is measured, and the percentage of the diameter before and after compression is calculated to obtain the hardness. If the hardness of the inner layer 112 is less than 50%, it cannot provide a good support effect for the concave-convex film layer 111, and the entire concave-convex film substrate group 11 is prone to collapse. If the hardness of the inner layer 112 is greater than 90%, the inner layer 112 has low elasticity and low applicability, thus requiring a high size of the heater of the aerosol delivery device, and cannot be adapted to an aerosol delivery device whose heater size is larger than the size of the heating hole 12. In the concave-convex film substrate group 11, if the hardness of the inner layer 112 is too large, when the entire consumable 100 is adapted to the central aerosol generating device, a large friction resistance is formed between the inner layer 112 and the central heater of the aerosol generating device, so that when the consumable 100 is inserted into or pulled out of the aerosol delivery device, the inner layer 112 is likely to damage the heater of the aerosol delivery device. In addition, the carbonized substances generated by the aerosol generating material on the inner layer 112 after heating are also likely to adhere to the heater, causing pollution to the heater, affecting the heating effect and service life of the heater, and further affecting the smell and experience of the consumable 100 when generating aerosol, reducing the user's inhalation experience of the consumable 100. Therefore, the hardness of the inner layer 112 in the grooved film substrate group 11 should be controlled between 50% and 90%, so as to ensure the structural strength of the inner layer 112, especially the structural strength at high temperature, while also ensuring the elasticity of the inner layer 112.

[0056] The thickness H2 of the inner layer 112 of the corrugated film substrate group 11 is 0.2 mm - 1 mm, that is, 0.2 mm ≤ H2 ≤ 1 mm. When the entire consumable 100 is adapted to the aerosol delivery device, the inner layer 112 is closest to the heater of the aerosol delivery device. Therefore, when the heater is heating, the temperature is relatively high. When the thickness of the inner layer 112 is greater than 1 mm, it will cause a certain hindrance to heat transfer, and it is easy for heat to accumulate in the inner layer 112, resulting in situations such as charring and carbonization of the inner layer; when the thickness of the inner layer 112 is less than 0.2 mm, it is too thin, and the supporting force for the adjacent corrugated film layer 111 is insufficient. Under the pressure of the corrugated film layer 111, the inner layer 112 is prone to collapse and other situations; therefore, setting the thickness of the inner layer 112 between 0.2 mm and 1 mm not only has sufficient supporting force for the corrugated film layer 111, improves the stability of the aerosol matrix 10, that is, improves the stability of the consumable 200, but also can better diffuse heat, thus avoiding the situation of being scorched by the heater close to the aerosol delivery device.

[0057] In the embodiment of the present application, the thickness H3 of the outer layer 113 of the corrugated film substrate group 11 is 0.05 mm - 0.3 mm, that is, 0.05 mm ≤ H3 ≤ 0.3 mm. Generally, due to the limited radial size of the consumable 100 (or the aerosol generation matrix 10), the overall radial size of the corrugated film substrate group 11 is limited. Therefore, if the thickness of the outer layer 113 is too large, the thickness of the remaining layers, such as the corrugated film layer 111, will be reduced, and the amount of aerosol generation material it can carry will be reduced, thus affecting the aerosol generation amount of the consumable 100; when the thickness of the outer layer 113 is too small, its ability to withstand external forces is weak, and it is prone to situations such as extrusion damage. Therefore, limiting the thickness of the outer layer 113 within a specific range can not only prevent damage but also ensure that other layers have sufficient thickness to meet the requirements for the amount of aerosol generated by the consumable 100.

[0058] In the embodiment of the present application, there are no special requirements for the materials of the inner layer 112 and the outer layer 113. In some examples, the inner layer 112 can be a tobacco sheet with an aerosol generation material or a non - tobacco sheet with an aerosol generation material; the outer layer 113 can also be a tobacco sheet with an aerosol generation material or a non - tobacco sheet with an aerosol generation material. In some other examples, the inner layer 112 can be a tobacco sheet with an aerosol generation material or a non - tobacco sheet with an aerosol generation material; the outer layer 113 can be a shielding layer with a fire - proof shielding function, such as a metal foil loaded with an aerosol generation material. In still other examples, the outer layer 113 can also be a metal foil without an aerosol generation material, such as aluminum foil, etc.

[0059] In the embossed film substrate group 11 provided by the present application, along the circumferential direction of the heating holes 12, the inner layer 112 or the outer layer 113 has two oppositely arranged side edges, and at least one side edge has an extension part (not shown in the figure), and the two side edges are fixedly connected through the extension part (not shown in the figure). In this embodiment, when the embossed film layer 111, the inner layer 112, and the outer layer 113 of the embossed film substrate group 11 are wound, when the inner layer 112 located inside the embossed film layer 111 and the outer layer 112 located outside the embossed film layer 111 are wound, at least one side edge of the outer layer 113 is provided with an extension part (not shown in the figure) and at least one side edge of the inner layer 112 is provided with an extension part (not shown in the figure). The extension part of the outer layer 113 is fixedly connected to the other side edge of the outer layer 113 or the extension part of the other side edge, and the extension part of the inner layer 112 is fixedly connected to the other side edge of the inner layer 112 or the extension part of the other side edge to form a cylindrical structure.

[0060] In this embodiment, the consumable 100 includes an aerosol generating matrix 10, a support section 20, and a filter section 30. The aerosol generating matrix 10 and the filter section 30 are respectively located on the two axial sides of the support section 20.

[0061] Exemplarily, the support section 20 is a hollow tubular structure, and the support section 20 is one of a hollow paper tube, a cellulose acetate tube, or an aluminum foil tube. The main function of the support section 20 is to provide support and cooling. The support section 20 can provide effective structural support for the entire consumable 100, especially to ensure the structural strength at high temperatures. Moreover, the support section 20 can also achieve a good cooling effect, avoiding discomfort caused by the excessive temperature of the aerosol when the user sucks. The aperture in the hollow tubular structure of the support section 20 is relatively large, which is conducive to the aerosol gathering towards the center and being sucked by the user, and also makes the aerosol have better agglomeration.

[0062] Exemplarily, the filter section 30 is a solid cellulose acetate structure, and the material of the filter section 30 includes, but is not limited to, one or a combination of more of PE (polyethylene), PLA (polylactic acid), PBAT (Poly(butyleneadipate - co - terephthalate)), PP (polypropylene), cellulose acetate, and propylene fiber materials. And the solid structure of the filter section 30 means a structure with micropores inside. The aerosol passes through the micropores formed by the filter section 30, thereby filtering harmful components in the aerosol and at the same time adjusting the draw resistance to avoid discomfort caused by too small draw resistance when the user sucks.

[0063] In this embodiment, the consumable 100 further includes a plug section 40 provided at the end of the aerosol-forming substrate 10. The plug section is a membrane layer, a housing, or a solid columnar structure through which air can pass, and has pores for gas to pass through. The plug section 40 is located at the end of the aerosol-forming substrate 10. When the heater of the aerosol delivery device is inserted into the consumable 100, it needs to pass through the plug section 40 first and then enter the aerosol-forming substrate 10. The plug section 40 can space the aerosol delivery device from the aerosol-forming substrate 10, avoiding the problem that the aerosol-forming substrate 10 is taken out during the insertion and removal of the aerosol delivery device from the consumable 100, thus effectively solving the problem that it is difficult to clean the periphery of the heating element of the aerosol delivery device due to aerosol residue.

[0064] In this embodiment, the consumable 100 further includes a wrapping layer (not shown in the figure) provided on the outer circumferential surfaces of the aerosol-forming substrate 10, the support section 20, the filter section 30, and the plug section 40. Through this wrapping layer, the aerosol-forming substrate 10 and the functional sections of the consumable 100 are connected as a whole. The wrapping layer has a certain hardness, which can play a certain protective role for the aerosol-forming substrate 10, reduce the risk of the aerosol-forming substrate 10 being directly exposed to the outside, reduce the probability of the aerosol-forming substrate 10 getting damp and deteriorating, and at the same time, can also reduce the risk of other functional sections of the consumable 100 being directly in contact with the external environment and being polluted.

[0065] The aerosol-forming substrate 10, the support section 20, the filter section 30, and the plug section 40 in the consumable 100 are all coaxial cylinders with a constant outer diameter, and the length directions of the support section 20, the filter section 30, and the plug section 40 are consistent with the axial direction of the aerosol-forming substrate 10. The material of the wrapping layer is not limited, including but not limited to one or a combination of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE, and PBAT.

[0066] Exemplarily, the wrapping layer can be a single-layer or double-layer structure. When the wrapping layer is a single layer, the aerosol-forming substrate 10, the support section 20, the filter section 30, and the plug section 40 can be wrapped simultaneously. When the wrapping layer is a double layer, one wrapping layer can be used to wrap the aerosol-forming substrate 10 first, and then another wrapping layer can be used to wrap the aerosol-forming substrate section 10, the support section 20, the filter section 30, and the plug section 40, or, one wrapping layer can be used to wrap the support section 20 and the filter section 30 first, and then another wrapping layer can be used to wrap the aerosol-forming substrate section 10, the support section 20, the filter section 30, and the plug section 40, or, other wrapping methods can also be adopted for the wrapping layer.

[0067] Second Embodiment Please refer to Figure 4, is a schematic diagram of a consumable 200 suitable for an aerosol delivery device provided by the second embodiment of the present application.

[0068] A consumable 200 suitable for an aerosol delivery device provided by the second embodiment of the present application includes an aerosol generating matrix 50 and a functional section provided at an end of the aerosol generating matrix 50. In this embodiment, the aerosol generating matrix 50 is as Figure 5 and Figure 6 shown.

[0069] As Figure 5 shown, the aerosol generating matrix 50 in the consumable 200 is a cylindrical structure with opposite first and second ends and a side surface, and a heating hole 12 penetrating from the first end to the second end is provided inside. The aerosol generating matrix 50 includes a concavo-convex textured film substrate group 11 disposed around the heating hole 12.

[0070] As Figure 6 shown, the concavo-convex textured film substrate group 11 in the aerosol generating matrix 50 includes a concavo-convex textured film layer 111 and an outer layer 113 located on the outermost side of the concavo-convex textured film substrate group 11. The concavo-convex textured film substrate group 11 forms a plurality of air flow channels 13' communicating with the heating hole 12 and a plurality of air flow channels 13" formed by enclosing the concavo-convex textured film layer 111 and the outer layer 113 between the concavo-convex textured film layer 111 and the heating hole 12. A plurality of air flow channels 13' (13") all penetrate from the first end to the second end of the aerosol generating matrix 50.

[0071] In this embodiment, the concavo-convex textured film layer 111 of the concavo-convex textured film substrate group 11 is disposed around the heating hole 12 and is wound and folded around the heating hole 12 to form a plurality of ridges and a plurality of valleys. Among them, a plurality of ridges of the concavo-convex textured film layer 111 are in contact with the outer layer 113, and a plurality of valleys are evenly distributed on the circumference of the heating hole 12.

[0072] In this embodiment, a plurality of valleys of the concavo-convex textured film layer 111 are disposed around the heating hole 12, and the plurality of valleys can be fixedly connected by an adhesive. Thus, the stability of the concavo-convex textured film layer 111 can be increased, thereby improving the stability of the entire consumable.

[0073] In this embodiment, both the concavo-convex textured film layer 111 and the outer layer 113 contain aerosol generating materials, and the content of the aerosol generating material in the outer layer 113 is less than or equal to the content of the aerosol generating material in the concavo-convex textured film layer 111.

[0074] In this embodiment, along the circumferential direction of the heating hole 12, the outer layer 113 has two oppositely arranged side edges, and at least one side edge has an extension part (not shown in the figure). The two side edges are fixedly connected through the extension part (not shown in the figure). That is, when the embossed film layer 111 and the outer layer 113 of the embossed film substrate group 11 are wound, the outer layer 113 has two oppositely arranged side edges (not shown in the figure) along the winding direction, and at least one side edge is provided with an extension part (not shown in the figure). The extension part overlaps with the side edge on the other side or the extension part of the side edge on the other side in the circumferential direction and is fixed (for example, adhesively fixed) in the overlapping area, so that the entire embossed film substrate group 11 forms an annular cylindrical structure having oppositely arranged first end 10A and second end 10B and a side surface.

[0075] In this embodiment, the consumable 200 includes an aerosol generating matrix 50, a support section 20, and a filter section 30. The aerosol generating matrix 50 and the filter section 30 are respectively located on the two axial sides of the support section 20, and the aerosol generating matrix 50 and the filter section 30 are respectively located at the two end portions of the consumable 200.

[0076] Third Embodiment Please refer to Figure 7 , which is a front view of an aerosol generating matrix 60 in a consumable suitable for an aerosol delivery device provided by the third embodiment of the present application.

[0077] A consumable suitable for an aerosol delivery device provided by the third embodiment of the present application includes an aerosol generating matrix 60. The aerosol generating matrix 60 is an annular cylindrical structure having opposite first and second ends and a side surface, and a heating hole 12 penetrating the first and second ends is provided inside. The aerosol generating matrix 60 includes an embossed film substrate group 11 arranged around the heating hole 12. The embossed film substrate group 11 includes an embossed film layer 111 and an inner layer 112 located at the innermost side of the embossed film substrate group 11. The embossed film layer 111 is arranged around the heating hole 12 and is wound and folded around the heating hole 12 to form a plurality of ridges and a plurality of valleys. Among them, the plurality of ridges of the embossed film layer 111 are evenly distributed on the outer circumference of the heating hole 12, and an air flow channel 132 is formed between two adjacent ridges. The plurality of valleys of the embossed film layer 111 are in contact with the inner layer 112, and an air flow channel 131 is formed by enclosing two adjacent valleys and the inner layer 112.

[0078] In this embodiment, both the embossed film layer 111 and the inner layer 112 contain an aerosol generating material, and the content of the aerosol generating material in the inner layer 112 is greater than the content of the aerosol generating material in the embossed film layer 111.

[0079] In this embodiment, along the circumferential direction of the heating hole 12, the inner layer 112 has two oppositely arranged side edges, and at least one of the side edges has an extension part (not shown in the figure), and the two side edges are fixedly connected through the extension part (not shown in the figure). That is, when the concavo-convex pattern film layer 111 and the inner layer 112 of the concavo-convex pattern film substrate group 11 are wound, the inner layer 112 has two oppositely arranged side edges (not shown in the figure) along the winding direction, and at least one of the side edges is provided with an extension part (not shown in the figure), and the extension part overlaps with the other side edge or the extension part of the other side edge in the circumferential direction and is fixed (such as adhesively fixed) in the overlapping area, so that the entire concavo-convex pattern film substrate group 11 forms an annular cylindrical structure having oppositely arranged first end 10A and second end 10B and a side surface.

[0080] Fourth Embodiment Please refer to Figure 8 , which is a front view of the aerosol generation matrix 70 in a consumable suitable for an aerosol delivery device provided by the fourth embodiment of the present application.

[0081] A consumable suitable for an aerosol delivery device provided by the fourth embodiment of the present application includes an aerosol generation matrix 70. The aerosol generation matrix 70 is an annular cylindrical structure having opposite first and second ends and a side surface, and is internally provided with a heating hole 12 penetrating the first and second ends. The aerosol generation matrix 70 includes a concavo-convex pattern film substrate group 11 disposed around the heating hole 12. The concavo-convex pattern film substrate group 11 includes a concavo-convex pattern film layer 111, an inner layer 112 located at the innermost side of the concavo-convex pattern film substrate group 11, and an outer layer 113 located at the outermost side of the concavo-convex pattern film substrate group 11.

[0082] In this embodiment, as Figure 8 shown, the concavo-convex pattern film layer 111 forms a plurality of ridges and a plurality of valleys in the outer circumferential direction of the heating hole 12. The plurality of ridges are in contact with the outer layer 113, and the plurality of valleys are in contact with the inner layer 112. The bending angles of the ridges and the valleys of the concavo-convex pattern film layer 111 are different, and the cross-sectional shape of the concavo-convex pattern film layer 111 is a regular V-shaped shape in a radial pattern. The V-shaped structure of the concavo-convex pattern film layer 111 is inclined along the radial direction of the heating hole 12, so that the cross-sectional area of the air flow channel 133 enclosed between the concavo-convex pattern film layer 111 and the outer layer 113 is larger than the cross-sectional area of the air flow channel 134 enclosed between the concavo-convex pattern film layer 111 and the inner layer 112.

[0083] Fifth Embodiment Please refer to Figure 9 , which is a front view of the aerosol generation matrix 80 in a consumable suitable for an aerosol delivery device provided by the fifth embodiment of the present application.

[0084] The consumable provided by the fifth embodiment of the present application includes an aerosol - generating substrate 80. The aerosol - generating substrate 80 is in a cylindrical - ring structure with opposite first and second ends and a side surface, and a heating hole 12 penetrating from the first end to the second end is arranged inside the aerosol - generating substrate 80. The aerosol - generating substrate 80 includes a concavo - convex - patterned film substrate group 11 arranged around the heating hole 12. The concavo - convex - patterned film substrate group 11 includes at least two concavo - convex - patterned film layers 111, and the at least two concavo - convex - patterned film layers 111 are stacked along the radial direction of the heating hole 12.

[0085] As Figure 9 shown, in this embodiment, the concavo - convex - patterned film substrate group 11 includes two concavo - convex - patterned film layers 111, and the two concavo - convex - patterned film layers 111 are stacked along the radial direction of the heating hole 12. In this embodiment, the concavo - convex - patterned film layer 111 closer to the heating hole 12 and the concavo - convex - patterned film layer 111 farther from the heating hole 12 are sleeved with each other along the radial direction of the heating hole 12. The wall thickness of the concavo - convex - patterned film layer 111 is the same in the same layer, and the wall thickness can be the same in different layers or can be set with different thickness values between 0.1 mm and 0.8 mm. In this embodiment, the wall thickness of the concavo - convex - patterned film layer 111 closer to the heating hole 12 is different from that of the concavo - convex - patterned film layer 111 farther from the heating hole 12. In this embodiment, both of the two concavo - convex - patterned film layers 111 contain aerosol - generating materials. The stacked arrangement of two or more concavo - convex - patterned film layers 111 can, on the one hand, improve the stability of the formed aerosol - generating substrate 80, and on the other hand, can also increase the content of its aerosol - generating materials, thereby enhancing the overall stability and aerosol concentration of the consumable 100, etc.

[0086] As Figure 9 shown, in this embodiment, the concavo - convex - patterned film substrate group 11 further includes a support layer 114 arranged between adjacent concavo - convex - patterned film layers 111. The support layer 114 is arranged between adjacent concavo - convex - patterned film layers 111 and is used to contact the ridges or valleys formed on the concavo - convex - patterned film layer 111 to support the two adjacent concavo - convex - patterned film layers 111, so as to achieve the structural stability of the entire concavo - convex - patterned film substrate group 11 in the consumable.

[0087] In some examples, the hardness of the support layer 114 can be greater than or equal to the hardness of the inner layer 112. Since the support layer 114 is closer to the outside of the aerosol - generating substrate 80 than the inner layer 112, the larger its diameter is towards the outside, and the greater the mass of the concavo - convex - patterned film layer 111 to be supported is. Therefore, it is necessary to set the hardness of the support layer 114 to be greater than or equal to the hardness of the inner layer 112, so as to further enhance the stability of the entire consumable 100.

[0088] Furthermore, the support layer 114 contains an aerosol - generating material, and the content of the aerosol - generating material in the support layer 114 is greater than or equal to the content of the aerosol - generating material in the corrugated film layer 111. When the support layer 114 contains an aerosol - generating material, in terms of mass fraction, the percentage of the mass of the aerosol - generating material contained in the support layer 114 in the total mass of the entire support layer 114 should be greater than the percentage of the mass of the aerosol - generating material contained in the corrugated film layer 111 in the total mass of the entire corrugated film layer 111, so as to ensure that the aerosol concentration released by the consumable remains at a substantially consistent level throughout the process of the user sucking on the consumable.

[0089] Sixth Embodiment Please refer to Figure 10 , which is a front view of the aerosol - generating matrix 90 in a consumable suitable for an aerosol delivery device provided by the sixth embodiment of the present application.

[0090] The consumable provided by the sixth embodiment of the present application includes an aerosol - generating matrix 90. The aerosol - generating matrix 90 has a cylindrical structure with opposite first and second ends and a side surface, and a heating hole 12 running through the first end to the second end is provided inside the aerosol - generating matrix 90. The aerosol - generating matrix 90 includes a corrugated film substrate group 11 arranged around the heating hole 12.

[0091] As Figure 10 shown, in this embodiment, the corrugated film substrate group 11 includes two corrugated film layers 111. The two corrugated film layers 111 are stacked along the radial direction of the heating hole 12, and a support layer 114 may not be provided between adjacent two corrugated film layers 111. In this embodiment, as Figure 10 shown, the two corrugated film layers 111 can be stacked along the radial direction of the heating hole 12. In some other examples, the two corrugated film layers 111 can be sleeved with each other along the radial direction of the heating hole 12 (not shown), that is, the ridges of the corrugated film layer 111 closer to the heating hole 12 can be embedded between the air flow channels 13 formed by the other corrugated film layer 111. The wall thickness of the corrugated film layer 111 can be the same in the same layer and different in different layers.

[0092] As Figure 10As shown, in this embodiment, the uneven-texture film layer 111 of the uneven-texture film substrate group 11 close to the heating hole 12 forms a plurality of ridges and a plurality of valleys in the radial direction of the heating hole 12, and the uneven-texture film layer 111 far from the heating hole 12 also forms a plurality of ridges and a plurality of valleys in the radial direction of the heating hole 12. Among them, the plurality of ridges on the uneven-texture film layer 111 close to the heating hole 12 are in contact with the plurality of valleys on the uneven-texture film layer 111 far from the heating hole 12, and the air flow channels 13 on the uneven-texture film layer 111 close to the heating hole 12 communicate with the air flow channels on the uneven-texture film layer 111 far from the heating hole 12 in the radial direction of the heating hole 12. The plurality of valleys of the uneven-texture film layer 111 close to the heating hole 12 are in contact with the inner layer 112 and enclose each other to form the air flow channel 13, and the plurality of ridges on the uneven-texture film layer 111 far from the heating hole 12 are in contact with the outer layer 113 and enclose each other to form the air flow channel 13.

[0093] In this embodiment, at least one of the two uneven-texture film layers 111 contains an aerosol-forming material. That is, the uneven-texture film layer 111 close to the heating hole 12 and / or the uneven-texture film layer 111 far from the heating hole 12 contains an aerosol-forming material. The two uneven-texture film layers 111 are stacked and in contact with each other between the inner layer 112 and the outer layer 113, which not only provides structural support but also provides an aerosol-forming material, enabling the uneven-texture film substrate group 11 to release aerosol when heated.

[0094] Seventh Embodiment The present application also provides an aerosol supply system, including an aerosol delivery device and the consumable 100 provided in any of the above embodiments. When the consumable 100 is connected to the aerosol delivery device, the aerosol delivery device is configured to heat the consumable 100 so that the consumable 100 generates aerosol. The consumable 100 can be used in a pluggable and detachable manner with the aerosol delivery device. The aerosol delivery device provides thermal energy for the consumable 100 and heats the consumable 100, so that after the aerosol-forming material contained in the aerosol-forming matrix 10 of the consumable 100 is released, aerosol is formed for the user to inhale.

[0095] The aerosol delivery device includes a central heater. When the consumable 100 is connected to the aerosol delivery device, the central heater is configured to be at least partially located within the heating hole 12 of the consumable 100. When the aerosol delivery device is used in cooperation with the consumable 100, the heating hole 12 in the aerosol-forming matrix 10 of the consumable 100 is inserted into the aerosol delivery device, so that a part of the structure of the central heater in the aerosol delivery device can extend into the heating hole 12 inside the aerosol-forming matrix 10. The central heater heats the aerosol-forming matrix 10 in the consumable 100 to release aerosol.

[0096] In an aerosol supply system, along the radial direction of the heating holes 12 of the aerosol generation matrix 10 in the consumable 100, the maximum length of the heating holes 12 is L1, and the maximum length of the central heater is L2. The maximum length L1 of the heating holes 12 and the maximum length L2 of the central heater satisfy the relationship: L1:L2 = (0.6 - 1.2):1, that is, 0.6 ≤ L1 / L2 ≤ 1.2. Generally, the maximum length L2 of the central heater of the aerosol delivery device along the radial direction of the heating holes is 2 mm - 3 mm. Correspondingly, the maximum length L1 of the heating holes 12 in the radial direction under the satisfied relationship is between 1.2 mm and 3.6 mm. The heating holes 12 are provided in the aerosol generation matrix 10 of the consumable 100, so that there is enough space for heating the aerosol generation matrix 10 in the consumable 100 and enough space to arrange the uneven texture film substrate group 11 with aerosol generation materials, and it can also be adapted to the central heating type aerosol delivery device. The maximum length L1 of the heating holes 12 in the radial direction is between 0.6 times and 1.2 times the maximum length L2 of the central heater in the radial direction, which can reduce the friction force between the aerosol generation matrix 10 and the central heater in the aerosol delivery device, effectively solve the problem that the central heater is damaged due to excessive friction force when the consumable 100 is inserted and removed in the aerosol delivery device, and at the same time, it can also improve the service life of the central heater of the aerosol delivery device, thereby ensuring that the aerosol supply system always maintains a stable heating effect and a stable aerosol generation concentration when using the above-mentioned consumable 100, and enhancing the suction experience of the user when using the consumable 100.

[0097] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
