Description

Technical Field

[0001] This invention relates to the field of tobacco product technology, and more specifically, to a consumable for heated non-combustible aerosol products and its application. Background Technology

[0002] Tobacco is an important economic crop, and tobacco products such as cigarettes and heated tobacco products have a wide consumer market worldwide. In the manufacturing process of tobacco products, the smoke-generating material is one of the key factors characterizing the quality of tobacco products, determining their flavor, draw resistance, and other characteristics. Therefore, the preparation of the smoke-generating material is crucial for providing a richer and / or easier smoking experience.

[0003] Currently, the traditional preparation of heated tobacco aerosol products mainly involves two steps: shredding and compounding into rods. First, the tobacco raw material is shredded. Then, using compounding technology, the shredded tobacco raw material, cooling elements, and filter tips are combined together, and finally, the product is cut into segments to obtain the finished heated tobacco aerosol product. However, shredding equipment is expensive, requires many pieces of equipment, involves complex processes, and is slow, making it unsuitable for large-scale production. Furthermore, heated tobacco aerosol products prepared using this method are prone to uneven heating, which not only affects aroma volatilization but also leads to unstable draw resistance.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a consumable for heating non-combustible aerosol products and its application, which can achieve uniform heating, ensure uniform evaporation of aroma, and ensure stable absorption resistance.

[0006] The embodiments of the present invention are implemented as follows:

[0007] In a first aspect, the present invention provides a consumable for heating non-combustible aerosol products, comprising at least two layers of spiral material, the spiral material being a sheet structure, multiple layers of spiral material being spirally wound and overlapping each other to form a cylindrical structure with hollow holes, each layer of spiral material comprising a main body and an edge portion, the edge portion being located at opposite ends of the main body, and after the spiral material is spirally wound, a butt joint is provided between two adjacent edge portions of the spiral, so that the number of layers in the cross section of the consumable is the same everywhere, the gap of the butt joint is less than 1.1 mm, and the tube diameter of each layer of spiral material is consistent.

[0008] Among them, the rolled material includes at least aerosol-generated sheets.

[0009] Optionally, the butt joint between adjacent edges of the outermost spiral after the outermost layer of coiled material is wound is less than 0.1 mm.

[0010] Optionally, the main body of the outermost layer of roll material covers the butt joint of the adjacent second outermost layer of roll material.

[0011] Preferably, the centerline region of the outermost layer of roll material covers the joint of the adjacent second outermost layer of roll material.

[0012] Optionally, the consumable includes three or more layers of roll material, with the orthographic projection area of ​​the main body of the outermost roll material covering the joint of any other roll material layers.

[0013] Optionally, each layer of the roll material has the same inclination angle, and the angle between the tangent of the butt joint and the central axis of the cylindrical consumable is 25° to 80°.

[0014] Preferably, the ratio of the diameter of the hollow hole to the width of the rolled material is 0.1 to 0.7.

[0015] Optionally, the gap between the butt joints is less than 1.1 mm.

[0016] Optionally, the consumable with a cylindrical structure has 2 to 8 layers in its cross-section, preferably 3 to 4 layers.

[0017] Preferably, the outer diameter of the consumable is 7.1 mm ± 10% or 5.3 mm ± 10%.

[0018] Preferably, the diameter of the hollow hole in the consumable is greater than 1.5 mm; more preferably, the diameter of the hollow hole in the consumable is 1.5 mm to 4 mm.

[0019] Preferably, the length of the consumable is 7mm to 84mm.

[0020] Alternatively, the roll material may also include at least one of filler paper, fragrance paper, and metal foil.

[0021] Preferably, the aerosol-generated sheet is reconstituted tobacco paper, and the raw materials for reconstituted tobacco paper include at least one of papermaking reconstituted tobacco, slurry reconstituted tobacco, dry reconstituted tobacco, and roll-pressed reconstituted tobacco.

[0022] Secondly, the present invention provides a heat-not-burn aerosol product, comprising an outer packaging paper, wherein a filter section and a smoke-generating section are sequentially disposed within the outer packaging paper, and the smoke-generating section is a consumable as described in any of the foregoing embodiments.

[0023] Optionally, the heating method for heating non-combustible aerosol products includes electromagnetic heating or contact heating.

[0024] Optionally, a cooling section may also be included between the filtration section and the smoke generation section.

[0025] Thirdly, the present invention provides the use of a consumable as described in any of the foregoing embodiments in the preparation of tobacco products.

[0026] The beneficial effects of the embodiments of the present invention are:

[0027] This invention provides a consumable for heated non-combustible aerosol products and its application. The consumable has a spirally wound structure, with a butt joint formed between adjacent edges of the winding material within the same layer. Therefore, the winding materials do not contact each other within the same layer, ensuring that the cross-sectional number of layers is the same throughout the consumable, thus guaranteeing uniformity. This structure not only significantly improves the strength of the consumable but also ensures uniform heating throughout, resulting in uniform aerosol overflow after heating, further guaranteeing the stability of the suction resistance. The hollow interior of the wound structure serves as an airflow channel, ensuring the stability of the suction resistance. Furthermore, the winding material includes at least an aerosol-generating sheet. When the aerosol-generating sheet is heated, it generates aerosol, which overflows through the butt joints in each layer of winding material and then into the airflow channel in the middle of the consumable, improving the user's vaping experience. The combination of the butt joints and the hollow structure makes the overflow of aerosol and smoke more stable, ensuring the stability of the suction resistance during vaping. This method can be achieved by winding and twisting, which reduces equipment investment, lowers the difficulty of the process, improves production efficiency, and is conducive to realizing large-scale industrial production.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Please refer to Figure 1 and Figure 2 In a first aspect, the present invention provides a consumable 100 for heating non-combustible aerosol products, comprising at least two layers of spiral material 110, the spiral material 110 having a sheet-like structure, the multiple layers of spiral material 110 being spirally wound and overlapping each other to form a cylindrical structure with hollow holes, the hollow holes inside the consumable 100 being airflow channels 112.

[0039] It should be noted that the consumable 100 used in the heated non-combustible aerosol product is a smoke-generating material of the heated non-combustible aerosol product 10. By heating the consumable 100, the coiling material 110 in the consumable 100 will evaporate and generate aerogel, providing users with a suction experience.

[0040] Each layer of spiral material 110 includes a main body and edge portions. The edge portions are located at opposite ends of the main body. After the spiral material 110 is spirally wound, a butt joint 111 is provided between two adjacent edge portions. After the outermost layer of spiral material 118 is wound, the adjacent edge portions of the spiral contact but do not overlap. After the next outermost layer of spiral material 110 is wound, a butt joint 111 is formed between its adjacent edge portions, so that the number of layers in the cross-section of the consumable 100 is the same everywhere. The purpose of providing butt joints 111 in the inner layers is to facilitate the overflow of aerosols. However, the outermost layer needs to ensure that the overall strength of the consumable 100 meets the requirements. Therefore, it is not necessary to deliberately leave a butt joint 111 of a certain width. It is sufficient to ensure that two adjacent edges contact but do not overlap after winding. The meaning of contact but not overlap is that there is a very small gap between two adjacent edges of the outermost layer of spiral material 110 after winding, which can be ignored.

[0041] Among them, the roll-to-roll material 110 includes at least an aerosol-generated sheet.

[0042] It is understandable that, in order to form the aforementioned consumable 100, a single sheet of winding material 110 can be wound to form one layer of the consumable 100. Therefore, the number of layers in the consumable 100 is the same as the number of sheets of winding material 110. When the consumable 100 has a structure of three or more layers, the layers are arranged sequentially from the outermost layer to the innermost layer: the first layer, the second layer, the third layer, and so on. The first layer is the outermost layer, the second layer is the second outermost layer, and the third layer and subsequent layers are collectively referred to as inner layers.

[0043] Please refer to Figure 2 and Figure 3 Taking one layer of consumable 100 wrapped with a roll of material 110 as an example, the roll of material 110 is a rectangular or strip-shaped sheet structure with a width of 115. The two long sides perpendicular to the width of 115 are the first long side 113 and the second long side 114, which are the edge portions.

[0044] When the spiral material 110 is spirally wound to form the consumable 100, the width 115 of the spiral material 110 is wound at an angle to the central axis. The first long side 113 will first spirally wound to form a curved surface. After one turn, the second long side 114 will be wound to be parallel to the first long side 113 everywhere. The first long side 113 and the second long side 114 do not overlap each other, and there is a butt joint 111 between the first long side 113 and the second long side 114. The number of cross-sectional layers of the consumable 100 obtained by winding in the above manner is the same everywhere. It can be understood that the cross-section here refers to the cross-section perpendicular to the axis of the consumable 100.

[0045] Furthermore, the consumable 100 provided by the present invention uses a winding material 110 that includes at least an aerosol generating sheet. The aerosol generating sheet is a sheet-like structure made of a material with smoke-generating ability, generally made from various recycled tobacco leaves, and is in the form of thin paper. When heated, the aroma components of tobacco will volatilize and generate aerosols. These aerosols will overflow along the joint seams 111 of each layer of the consumable 100. The hollow consumable 100 forms an airflow channel 112 in its internal cavity, which is beneficial to the user's smoking experience. Furthermore, since the aerosol generating sheet is evenly distributed during the winding process and the number of layers in the cross-section of the consumable 100 is equal everywhere, the consumable 100 can be heated evenly, further ensuring the stability of the draw resistance.

[0046] In an optional embodiment, the aerosol-generating sheet is recycled tobacco paper, and the raw materials for the recycled tobacco paper include at least one of paper-processed recycled tobacco, slurry-processed recycled tobacco, dry-processed recycled tobacco, and roll-pressed recycled tobacco. The above are only some examples of the sources of the aerosol-generating sheet. In practical applications, the aerosol-generating sheet can be paper made from tobacco materials capable of producing tobacco aroma and smoking experience, obtained by any existing method.

[0047] Since aerosol generating sheets are one of the materials that provide the necessary suction experience for consumable 100, the roll-to-roll material 110 provided by the present invention includes at least aerosol generating sheets. However, in order to adapt to various heating devices and the suction experience of various groups of people, the roll-to-roll material 110 in consumable 100 provided by the present invention also includes at least one of filling paper, fragrance paper and metal foil.

[0048] The filler paper can be any food-grade ordinary paper, and its function is to be wound as a filler or diluent material to form a hollow consumable 100. For example, assuming a conventional consumable 100 is formed by winding four layers of aerosol-generating sheets with a conventional tobacco concentration, when a consumable 100 with a lower tobacco concentration needs to be prepared, one or two layers of aerosol-generating sheets can be replaced with filler paper. Alternatively, if the selected aerosol-generating sheet has a high tobacco concentration, using all four layers of aerosol-generating sheets would result in a high tobacco concentration in the consumable 100; therefore, one layer of aerosol-generating sheet can be replaced with filler paper. Whether or not filler paper needs to be added and the amount of filler paper can be designed according to the actual vaping requirements.

[0049] Flavored paper is a tobacco product with a special aroma. It can be made by combining tobacco with other flavoring ingredients or by using non-tobacco ingredients alone. It can give consumable 100 a richer smoking experience. Therefore, depending on the design requirements of the product, one or more layers of consumable 100 can be designed as flavored paper.

[0050] By incorporating one or more layers of metal foil into the consumable 100, typically one layer, the consumable 100 containing the aforementioned metal foil can be adapted to a wider variety of heating devices. For example, the consumable 100 with metal foil can be heated not only by heat transfer but also by electromagnetic heating, thus adapting to heating devices with various heating methods.

[0051] In an optional embodiment, each layer of the roll material 110 has the same tilt angle. In order to ensure that the roll materials 110 do not overlap with each other in the same layer and can form a butt joint 111, the angle α between the tangent of the butt joint 111 and the central axis O of the cylindrical consumable 100 is 25° to 80°. It can also be understood that during the winding process, one end of the roll material 110 that has not yet been wound needs to be tightened before the winding is completed. Therefore, the angle β between the tightened end of the unwound roll material 110 and the axis of the consumable 100 is 25° to 80°.

[0052] Wherein, the tangent of the butt joint 111 and the central axis of the consumable 100 are located in two planes. Therefore, the included angle α here is the included angle when the two are translated into the same plane and intersect. The included angle α is 25° to 80°, for example, it can be any value among 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75° or 80°, or any range value and point value between any two values.

[0053] Preferably, the ratio of the diameter of the hollow hole to the width 115 of the coiled material 110 is 0.1 to 0.7. That is, the diameter of the hollow hole is smaller than the width 115 of the coiled material 110, so as to reduce the number of winding turns and improve the production efficiency of the consumable 100.

[0054] In some preferred embodiments, the ratio of the diameter of the hollow hole to the width 115 of the roll material 110 can be any value among 0.1, 0.2, 0.3, 0.4, 0.5, 0.6 or 0.7, or a range or point value between any two values.

[0055] In an optional implementation, to ensure uniform aerosol overflow and avoid uneven thickness of the consumable 100, the gap between the butt joints 111 satisfies the condition 0 mm < butt joint 111 < 1.1 mm. For example, the gap between the butt joints 111 can be any value from 1 mm, 0.9 mm, 0.8 mm, 0.7 mm, 0.6 mm, 0.5 mm, 0.4 mm, 0.3 mm, 0.2 mm, or 0.1 mm, or any range or point value between any two values. It should be noted that the multi-layered rolled material 110 in the consumable 100 must not overlap within each layer to ensure uniform heating of the consumable 100. The outermost rolled material 110 does not need to have intentionally wide butt joints 111; the first long side 113 and the second long side 114 can be kept adjacent to each other to better control the strength of the consumable 100. In addition to the outermost layer, all the inner layers of rolled material 110 need to have a relatively wide gap during the winding process to facilitate the overflow of aerosol, namely the aforementioned butt joint 111.

[0056] Please refer to Figure 5 In order to prevent the aerosol from overflowing too quickly and to improve the mechanical strength of the consumable 100 and prevent it from bending easily, preferably, the main body of the outermost layer of the roll material 110 covers the butt joint 111 of the adjacent inner layer of the roll material 110.

[0057] For example, a consumable 100 has a three-layer structure, consisting of an outermost layer of roll material 118, a second outermost layer of roll material 117, and an innermost layer of roll material 116, from the outside in. If the seams 111 of the three roll materials 110 completely overlap, the aerosol will overflow directly and rapidly from the seams 111 into the airflow channel 112, resulting in excessively fast overflow. Furthermore, this would lead to insufficient mechanical strength in the consumable 100, making it prone to bending. Therefore, the preferred solution is to cover the seam 111 of the second outermost layer of roll material 117 with the outermost layer of roll material 118. Whether the seams 111 of the innermost layer of roll material 116 and the second outermost layer of roll material 117 overlap can be determined as needed.

[0058] For example in Figure 5 In the middle, the butt joint 111 of the inner layer and the second outer layer of the roll material 117 overlaps, while the outermost roll material 118 covers the butt joint 111 of the second outer layer of the roll material 117.

[0059] Preferably, in order to further ensure the coverage of the butt joint 111 of the outermost layer of the roll material 118 over the second outermost layer of the roll material 117, the centerline region of the outermost layer of the roll material 118 covers the butt joint 111 of the second outermost layer of the roll material 117.

[0060] Among them, the centerline of the outermost layer of roll material 118 in the axial direction refers to the centerline that is parallel to the first long side 113 and the second long side 114 of the roll material 110, and whose endpoints bisect the width 115.

[0061] Please refer to Figure 3 and Figure 4 In order to further improve the mechanical strength of the product, more preferably, the seam 111 of the roll material 118 from the innermost layer to the outermost layer is covered by the roll material 110 of the adjacent inner layer.

[0062] Among them, the innermost layer of the roll material 110 refers to the roll material 110 located outside the innermost layer of the roll material 110.

[0063] For example, a consumable 100 has a three-layer structure, consisting of an outermost layer of roll material 118, a second outermost layer of roll material 117, and an innermost layer of roll material 116, from the outside to the inside. The second outermost layer of roll material 117 covers the butt joint 111 of the innermost layer of roll material 116, and the outermost layer of roll material 118 covers the butt joint 111 of the second outermost layer of roll material 117.

[0064] Preferably, in order to ensure that each layer other than the inner layer covers the joint 111 of the adjacent inner layer, the centerline region of the roll material 110 from the second inner layer to the outermost layer coincides with the joint 111 of the roll material 110 of the adjacent inner layer.

[0065] Among them, the centerline of the axial direction of the roll material 110 from the innermost layer to the outermost layer refers to the centerline that is parallel to the first long side 113 and the second long side 114 of the roll material 110 and whose endpoints bisect the width 115.

[0066] In an optional embodiment, the consumable 100 includes three or more layers of roll material 110, and the orthographic projection area of ​​the main body of the outermost roll material 118 covers the butt joint 111 of any other roll material 110 to ensure that the consumable 100 has high strength.

[0067] Furthermore, since the outer layer of the winding material 110 needs to cover the butt joint 111 formed by the adjacent inner layer of the winding material 110 during the winding process, it is inevitable that the number of cross-sectional layers at the left and right ends of the consumable 100 will not be consistent when the winding is just completed. This part of the consumable 100 needs to be cut and discarded in actual use. Moreover, the consumable 100 formed in one batch is relatively long, and it also needs to be cut into a suitable length before use in actual use.

[0068] In an optional embodiment, the consumable 100 with a cylindrical structure has 2 to 8 layers in its cross-section, preferably 3 to 4 layers. The number of layers in the cross-section of the consumable 100 can be set as needed, and the material of the roll-up material 110 for each layer can also be specifically selected as needed.

[0069] Preferably, the outer diameter of the consumable 100 is 7.1 mm ± 10% or 5.3 mm ± 10%.

[0070] Preferably, to ensure the width of the gas channel while ensuring that the outer diameter of the consumable 100 meets the requirements, the diameter of the hollow hole of the consumable 100 is greater than 1.5 mm. More preferably, the diameter of the hollow hole of the consumable 100 is 1.5 mm to 4 mm, for example, the diameter of the hollow hole of the consumable 100 is any value among 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm, or any range or point value between any two values.

[0071] The consumable 100 for heating non-combustible aerosol products formed by winding is a long, hollow cylindrical structure that needs to be cut into fixed lengths. Preferably, the length of the cut consumable 100 is 7mm to 84mm. For example, the inner diameter of the consumable 100 is any value among 7mm, 12mm, 20mm, 30mm, 40mm, 50mm, 60mm, 75mm or 84mm, or any range or point value between any two values.

[0072] Among them, compressive strength refers to the compressive strength along the tangential direction of the tube body of consumable 100; elastic modulus refers to the Young's elastic modulus along the cross-sectional direction of consumable 100.

[0073] Secondly, the present invention provides a heat-not-burn aerosol product 10, comprising an outer packaging paper 400, wherein a filter section 200 and a smoke-generating section are sequentially disposed within the outer packaging paper 400, and the smoke-generating section is a consumable 100 as described in any of the aforementioned embodiments.

[0074] In an optional embodiment, the heating method for heating the non-combustible aerosol product 10 includes electromagnetic heating or contact heating.

[0075] In an optional embodiment, a cooling section 300 is also included between the filtration section 200 and the smoke-generating section.

[0076] Thirdly, the present invention provides the use of a consumable 100 as described in any of the foregoing embodiments in the preparation of tobacco products.

[0077] The existing heated tobacco aerosol products (Category 10) require complex manufacturing processes, including cutting the tobacco into shreds and then combining them with cooling elements and filters. Furthermore, the uneven distribution of tobacco shreds during the compounding process leads to uneven heating of the heated tobacco aerosol products, affecting both the stable release of aroma and the stability of draw resistance during inhalation, thus impacting the smoking experience. Additionally, the heated tobacco aerosol products formed by compounding tobacco shreds lack stable, interconnected airflow channels (112) within the material, further affecting the uniformity of heating and the stability of draw resistance.

[0078] Based on this, the inventors propose a consumable 100 for heating non-combustible aerosol products. The consumable 100 is hollow, allowing for the formation of a stable and continuous airflow channel 112. The consumable 100 is formed by winding and splicing materials 110 together, with no overlap between layers during the winding process. Furthermore, the mechanical strength of the consumable 100 is improved by covering the inner layer seam with an outer layer. A butt joint 111 is provided between the edges of two adjacent layers of the same layer of the winding material 110, which facilitates the formation and flow of aerosols, thus providing the advantages of this invention. The heat-not-burning aerosol product 10 of the consumable 100, after heating, heats evenly due to the uniform distribution of the rolled material 110, and can form an aerosol evenly and stably. The aerosol can stably overflow along the butt joint 111 and be drawn in through the hollow airflow channel 112, ensuring the stability of the suction resistance during the suction process. At the same time, the combination of the design of the butt joint 111 and the hollow airflow channel 112 can also effectively reduce the suction resistance, giving users a better suction experience. In addition, the raw materials of the consumable 100 provided by the present invention are all plant materials, which are environmentally friendly and biodegradable.

[0079] Furthermore, the consumable 100 provided by this invention has a simple preparation method, which can be obtained by rolling. Compared with the traditional slicing and composite rod forming process, it does not require the setting of complex and expensive slicing equipment, resulting in low equipment investment. At the same time, it does not require a complex slicing process, which greatly simplifies the production process and improves the operating efficiency. It is suitable for large-scale industrial production and has good industrial applicability.

[0081] Please refer to Figures 1-4This embodiment provides a consumable 100 for heating non-combustible aerosol products, comprising three layers of spiral material 110. Each layer of spiral material 110 is spirally wound and overlaps each other to form a hollow cylindrical structure. The hollow area inside the consumable 100 is the airflow channel 112, and the diameter of the hollow hole in the consumable 100 is 4 mm. The second layer of spiral material 110 covers the butt joint 111 of the first layer of spiral material 110, and the third layer of spiral material 110 covers the butt joint 111 of the second layer of spiral material 110. After winding, it is cut into small segments with a length of 12 mm. The number of layers in the cross-section of the consumable 100 is the same everywhere. The parameters of each layer of spiral material 110 are shown in Table 1.

[0085] Example 2

[0086] Please refer to Figure 5 This embodiment provides a consumable 100 for heating non-combustible aerosol products, comprising three layers of spirally wound material 110. Each layer of spirally wound material 110 is spirally wound and overlapped to form a hollow cylindrical structure. The hollow area inside the consumable 100 is the airflow channel 112, and the diameter of the hollow hole in the consumable 100 is 4 mm. The butt joint 111 of the second layer of spirally wound material 110 coincides with the butt joint 111 of the first layer of spirally wound material 110. The third layer of spirally wound material 110 covers the butt joint 111 of the second layer of spirally wound material 110. After winding, it is cut into small segments with a length of 12 mm. The number of layers in the cross-section of the consumable 100 is the same everywhere, and the parameters of each layer of spirally wound material 110 are the same as in Embodiment 1.

The smoke-generating section can be any of the consumables 100 provided in embodiments 1 to 5 above, such as... Figure 6 As shown, the consumable 100 provided in Example 1 serves as the smoke-generating section of the heated non-combustible aerosol product 10 provided in this example.

[0108] Example 7

[0109] This embodiment provides a heat-not-combustible aerosol product 10, comprising a smoke-generating section, a cooling section 300, and a filtration section 200 connected in sequence. The smoke-generating section can be any of the consumables 100 provided in embodiments 1-5 above, such as... Figure 7 As shown, the consumable 100 provided in Example 1 serves as the smoke-generating section of the heated non-combustible aerosol product 10 provided in this example.

[0110] Comparative Example 1

[0111] This comparative example provides a heat-resistant non-combustible aerosol product 10, the preparation method of which includes cutting into shreds and compounding into rods, as detailed below:

[0112] S01, Shredding

[0113] The raw material selected is reconstituted tobacco leaf rolls made using the slurry method, with a width of 138mm, a thickness of 0.2mm, and a basis weight of 220g / m³. 2 With a tensile strength of 300 N / m and a moisture content of 8%, the material is cut into 1 mm wide filaments using a filament cutter, then gathered into rods through a flared mouth, wrapped with a layer of packaging paper, and cut into 12 mm segments. This material is equivalent to the consumable 100 in the embodiment of the present invention.

[0114] SO2, composite rod

[0115] The materials of the small section, the cooling section 300, and the filter section 200 are combined, and an outer layer of packaging paper 400 is wrapped around the outside of these three parts to form a complete heated non-combustible cigarette.

[0116] Comparative Example 2

[0117] This embodiment provides a consumable 100, which is largely the same as that in embodiment 3, except that the winding angle is 45° and the width of each layer of the roll material 110 is 10.0 mm.

[0118] The consumable 100 provided in this comparative example has an excessively large width 115 at the inner layer winding material 116 and the second inner layer winding material, causing each layer of paper to overlap and cover each other after winding, resulting in an uneven diameter of the cigarette stick after winding; the width 115 at the outermost layer winding material 118 and the second outermost layer winding material 117 is too small, resulting in too large a seam between each layer of paper, causing the winding between layers to be weak.

[0119] Experimental Example 1

[0120] The consumables 100 in Examples 1, 3-5 and Comparative Examples 1-2 were subjected to performance tests. The weight was measured using a balance, the total wall thickness was measured using a thickness gauge, the density was calculated, the strength was measured using a universal testing machine, and the elasticity was measured using a universal testing machine. The results are shown in Table 1.

[0121] Table 1 Performance of Consumable 100

[0122]

[0123] As shown in Table 1, the compressive strength along the tube cross-section and the Young's modulus in the cross-sectional direction of the consumable 100 in the embodiment are both superior to those of the comparative example. Comparative Example 1, being a consumable 100 formed by slicing reconstituted tobacco leaves, has the worst strength. Comparative Example 2, due to its improper winding method, resulting in overlapping layers, inconsistent tube diameters, gaps between layers, and weak adhesion, has lower strength than the embodiment.

[0124] Experimental Example 2

[0125] The consumables 100 obtained in Examples 1, 3-5 and Comparative Example 2 were all prepared into heat-not-burning aerosol products 10 using the method of Example 7. The suction performance of the heat-not-burning aerosol product 10 in Comparative Example 1 was tested. The suction resistance was tested using a cigarette suction resistance tester according to GB / T22838.5. The results are shown in Tables 2 and 3.

[0126] Table 2. Suction stability of heat-resistant non-combustible aerosol product 10

[0127]

[0128] Table 3. Suction performance of heated non-combustible aerosol product 10

[0129]

[0130]

[0131] As shown in Table 2, the heat-not-burning aerosol product 10 made from the consumable 100 provided in this embodiment of the invention has a lower overall suction resistance and more stable suction resistance, resulting in a more uniform heating effect, because the winding angle and width are matched, and the hollow tube setting retains a sufficient and stable airflow channel 112. Comparative Example 1 uses a traditional shredding and rolling process, where the airflow can only pass through the channels squeezed and twisted between the shreds, resulting in a larger overall suction resistance. Furthermore, the tobacco shreds of different cigarettes shrink differently when heated, causing changes in the airflow channel 112 and unstable suction resistance. Comparative Example 2 suffers from an unreasonable winding method, leading to overlap between the same layer and between layers, inconsistent tube diameter, gaps between layers, and poor adhesion. Therefore, the airflow channel 112 is unstable, and the suction resistance fluctuates greatly.

[0132] As shown in Table 3, Example 1, consisting of three layers of tobacco paper, has a high tobacco content and density, resulting in the best sensory quality during inhalation, with a strong strength, rich aroma, and abundant smoke. Example 2, consisting of three layers of tobacco paper plus a layer of flavored paper, retains the tobacco flavor while providing a wider range of taste experiences, with a moderate strength, moderate aroma, and abundant smoke. Example 3, consisting of two layers of tobacco paper, two layers of flavored paper, and a layer of metal foil, provides a richer flavor and is compatible with electromagnetic heating devices, offering a moderate strength, moderate aroma, and abundant smoke. Comparative Examples 1 and 2, due to unstable draw resistance, exhibit inconsistent strength, aroma, and smoke release.

[0133] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
