Description

Technical Field

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

[0002] Heat-not-burning (HNB) appliances are devices used to heat an aerosol-generating matrix without causing it to burn. HNB appliances generate aerosols by heating the aerosol-generating matrix at high temperatures, but the temperature is insufficient to burn the aerosol-generating matrix, thus forming the aerosol desired by the user.

[0003] In related technologies, heated non-combustible appliances generally employ two methods: circumferential heating of the aerosol-generating matrix and central heating. However, regardless of the heating method used, impurities are generated during the heating process, making them noticeable during user inhalation and significantly impacting the user's inhalation experience. Utility Model Content

[0004] In view of this, the main objective of the embodiments of this application is to provide a functional section pipe fitting, an aerosol generating product, and an aerosol generating system that can reduce impurities during the suction process.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows: A first aspect of this application provides a functional segment pipe fitting applied to an aerosol generating article, the aerosol generating article including a wrapping layer located outside the functional segment pipe fitting, the functional segment pipe fitting comprising: The inner layer of the tube encloses and forms a cavity; The outer layer of the tube is located outside the inner layer of the tube, and the inner layer, the outer layer of the tube, and the wrapping layer are made of the same material.

[0007] In one embodiment, the inner tube layer, the outer tube layer, and the wrapping layer are one of forming paper, cigarette paper, and cork paper.

[0008] In one embodiment, the functional segment pipe fitting further includes an intermediate layer located between the inner pipe layer and the outer pipe layer.

[0009] In one embodiment, the intermediate layer is one of sulfuric acid paper, forming paper, cigarette paper, and cork paper.

[0010] In one embodiment, the functional segment pipe fitting has a two-layer pipe structure; The thickness of at least one of the inner and outer layers of the tube is greater than or equal to 0.05 mm and less than or equal to 0.40 mm; and / or, The basis weight of at least one of the inner and outer layers of the tube is greater than or equal to 30 g / m³. 2 And less than or equal to 250g / m 2 .

[0011] In one embodiment, the functional segment pipe fitting has a three-layer pipe structure, and the functional segment pipe fitting further includes an intermediate layer located between the inner pipe layer and the outer pipe layer; The thickness of at least one of the inner layer, the outer layer, and the intermediate layer is greater than or equal to 0.033 mm and less than or equal to 0.267 mm; and / or, The basis weight of at least one of the inner tube layer, the outer tube layer, and the intermediate layer is greater than or equal to 20 g / m³. 2 And less than or equal to 180g / m 2 .

[0012] In one embodiment, the thickness of the functional segment pipe is greater than or equal to 0.10 mm and less than or equal to 0.80 mm.

[0013] A second aspect of this application provides an aerosol generating article, the aerosol generating article comprising a matrix section, a filter section, a coating layer, and any of the aforementioned functional segment pipes, the functional segment pipes being located between the matrix section and the filter section, and the coating layer at least covering the functional segment pipes.

[0014] A third aspect of this application provides an aerosol generation system, which includes an aerosol generation device and the aforementioned aerosol generation article.

[0015] This application provides a functional segment tubing, an aerosol generating product, and an aerosol generating system. The functional segment tubing includes an inner layer and an outer layer. The inner layer encloses and forms a cavity, and the outer layer is located outside the inner layer. The inner layer, outer layer, and outer sheath are made of the same material. During the heating of the matrix segment of the aerosol generating product by the aerosol generating device in the aerosol generating system, heat is transferred to the functional segment tubing and the outer sheath. Because the inner layer, outer layer, and outer sheath are made of the same material, the aerosol generated by the inner and outer layers after heating is the same as the aerosol generated by the outer sheath after heating, thereby reducing impurities and improving the user's suction experience.

[0018] In this application, the terms "inner" and "outer" orientations or positional relationships are based on the appendix. Figure 3 The orientation or positional relationship shown is for illustrative purposes only and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0019] One embodiment of this application provides a functional segment pipe fitting 10. Please refer to [link / reference]. Figure 1 , Figure 3 and Figure 5 It is applied to aerosol generating products, which include a wrapping layer 20 located outside the functional section pipe fitting 10. The functional section pipe fitting 10 includes an inner pipe layer 11 and an outer pipe layer 12, with the inner pipe layer 11 enclosing to form a cavity 11a.

[0020] The outer layer 12 is located outside the inner layer 11, and the inner layer 11, the outer layer 12, and the wrapping layer 20 are made of the same material.

[0021] Specifically, the inner layer 11 is the innermost structural layer of the functional section pipe fitting 10, defining the cavity 11a for airflow. The outer layer 12 is the outermost structural layer of the functional section pipe fitting 10.

[0022] The specific arrangement of the inner layer 11 and the outer layer 12 is not limited.

[0023] For example, the outer layer 12 is fitted over the outer side of the inner layer 11. The inner surface of the outer layer 12 overlaps at least partially with the outer surface of the inner layer 11. That is, the inner surface of the outer layer 12 may only partially overlap with the outer surface of the inner layer 11, such as the outer layer 12 only covering part of the outer surface of the inner layer 11, or the inner layer 11 only covering part of the inner surface of the outer layer 12. Alternatively, the inner surface of the outer layer 12 may completely overlap with the outer surface of the inner layer 11, meaning the areas of the inner surface of the outer layer 12 and the outer surface of the inner layer 11 are equal and completely coincident.

[0024] The materials of the inner tube layer 11, the outer tube layer 12, and the wrapping layer 20 can be determined according to the actual situation.

[0025] For example, the inner layer 11, the outer layer 12, and the wrapping layer 20 are made of paper. Using paper simplifies the manufacturing process of the functional section fitting 10, reduces costs, and provides good biodegradability. It should be noted that the inner layer 11, the outer layer 12, and the wrapping layer 20 must be made of the same type of paper.

[0026] The term "same material" here refers to the fact that the inner tube layer 11, the outer tube layer 12, and the wrapping layer 20 are made of the same material.

[0027] For example, the inner tube layer 11, the outer tube layer 12, and the wrapping layer 20 are all formed paper.

[0028] For example, the inner layer 11, the outer layer 12, and the wrapping layer 20 are all cigarette paper.

[0029] For example, the inner layer 11, the outer layer 12, and the wrapping layer 20 are all made of cork paper. In other words, the materials of the inner layer 11, the outer layer 12, and the wrapping layer 20 are exactly the same.

[0030] Using the above-mentioned types of paper materials makes them easier to process and has advantages such as biodegradability, environmental friendliness, simple production process, and low production cost. It can reduce the impact on the sensory quality of aerosol-generating products and bring users a pleasant experience.

[0031] Another embodiment of this application provides an aerosol-generating article; please refer to [link to relevant documentation]. Figure 1 The aerosol-generating product includes a matrix section 30, a filter section 40, a coating layer 20, and a functional section pipe 10 as described in any embodiment of this application. The functional section pipe 10 is located between the matrix section 30 and the filter section 40, and the coating layer 20 at least covers the functional section pipe 10.

[0032] Specifically, the wrapping layer 20 is a structural layer wrapped around the outside of the functional section pipe fitting 10. It may only wrap the functional section pipe fitting 10, or it may wrap around the outside of other structural sections in addition to the functional section pipe fitting 10. For example, the wrapping layer 20 wraps around the outside of the matrix section 30, the filter section 40, and the functional section pipe fitting 10.

[0033] It should be noted that the functional section fitting 10 is a pipe structure of a functional section located between the matrix section 30 and the filter section 40.

[0034] For example, the aerosol-generating product includes a cooling section located between the matrix section 30 and the filter section 40, and the cooling section includes a functional section fitting 10.

[0035] For example, the aerosol generating product includes a support section located between the matrix section 30 and the filter section 40, and the support section includes a functional section pipe 10.

[0036] For example, the aerosol generating product includes a support section and a cooling section located between the matrix section 30 and the filter section 40, and the support section and the cooling section each include a functional section pipe 10.

[0037] In related technologies, the outer wrapping layer and the functional section of heated non-burning (HNB) devices are not made of the same material (e.g., the functional section uses kraft paper, while the wrapping paper uses cigarette paper, tipping paper, or molded paper). When the substrate section is heated at 200°C to 350°C, heat is transferred to both the functional section and the wrapping layer. Because the materials are completely different, the aromas produced by the functional section and the wrapping layer when heated are different, making impurities flowing with the aerosol more noticeable and significantly reducing the user's vaping experience.

[0038] In the functional segment fitting 10 of this application embodiment, the inner layer 11 encloses and forms a cavity 11a, and the outer layer 12 is located outside the inner layer 11. The inner layer 11, the outer layer 12, and the wrapping layer 20 are made of the same material. During the heating of the matrix segment 30 of the aerosol-generating product by the aerosol generating device of the aerosol generating system, heat is transferred to the functional segment fitting 10 and the wrapping layer 20. Since the inner layer 11, the outer layer 12, and the wrapping layer 20 are made of the same material, the gas produced by the inner layer 11 and the outer layer 12 after heating is the same as the gas produced by the wrapping layer 20 after heating, thereby reducing impurities and improving the user's suction experience during the suction process.

[0039] In one embodiment, please refer to Figure 3The functional section pipe fitting 10 also includes an intermediate layer 13, which is located between the inner pipe layer 11 and the outer pipe layer 12. That is, the intermediate layer 13 is an intermediate pipe layer located between the inner pipe layer 11 and the outer pipe layer 12. By adding the intermediate layer 13, the hardness of the functional section pipe fitting 10 can be improved.

[0040] It should be noted that the material of the intermediate layer 13 can be the same as that of the inner layer 11 and the outer layer 12, thereby further reducing the generation of impurities.

[0041] Of course, in some embodiments, the material of the intermediate layer 13 may also be different from that of the inner layer 11 and the outer layer 12.

[0042] For example, the intermediate layer 13 is made of tracing paper, while the inner layer 11, outer layer 12, and wrapping layer 20 are made of one of the following: forming paper, cigarette paper, or cork paper. Tracing paper has the characteristics of low basis weight and high hardness compared to other types of paper. Therefore, using tracing paper for the intermediate layer 13 helps to reduce the wall thickness while increasing the hardness of the functional section pipe fitting 10. Furthermore, since the inner layer 11, outer layer 12, and wrapping layer 20 are made of the same material, they do not significantly affect the functional section pipe fitting 10.

[0043] It should be noted that the intermediate layer 13 can also be made of other materials.

[0044] For example, the intermediate layer 13 is formed paper, cigarette paper, or cork paper.

[0045] The number of structural layers in functional section pipe fitting 10 can be set according to actual conditions.

[0046] For example, please see Figure 5 The functional section pipe fitting 10 has a two-layer pipe structure. That is, the functional section pipe fitting 10 includes two structural layers (i.e., an inner pipe layer 11 and an outer pipe layer 12), which are bonded together. The two-layer pipe structure simplifies the manufacturing process of the functional section pipe fitting 10 and makes it lighter and thinner.

[0047] For example, the functional section pipe fitting 10 has a three-layer pipe structure, and the functional section pipe fitting 10 also includes an intermediate layer 13 located between the inner layer 11 and the outer layer 12. That is to say, the functional section pipe fitting 10 includes three structural layers (i.e., the inner layer 11, the intermediate layer 13, and the outer layer 12). The adoption of a three-layer pipe structure is beneficial to improving the rigidity of the functional section pipe fitting 10 and can improve the support performance of the functional section pipe fitting 10.

[0048] In one embodiment, the functional segment pipe fitting 10 has a two-layer pipe structure; the thickness of the inner layer 11 is greater than or equal to 0.05 mm and less than or equal to 0.40 mm, such as 0.05 mm, 0.10 mm, 0.15 mm, 0.20 mm, 0.25 mm, 0.30 mm, 0.35 mm, or 0.40 mm. Controlling the thickness of the inner layer 11 within the above range allows it to have a good supporting effect without being too thick.

[0049] In one embodiment, the functional segment pipe fitting 10 has a two-layer pipe structure; the thickness of the outer layer 12 is greater than or equal to 0.05 mm and less than or equal to 0.40 mm, such as 0.05 mm, 0.10 mm, 0.15 mm, 0.20 mm, 0.25 mm, 0.30 mm, 0.35 mm, or 0.40 mm. Controlling the thickness of the outer layer 12 within the above range allows it to have good support while avoiding excessive thickness.

[0050] In one embodiment, the functional section pipe fitting 10 has a two-layer pipe structure; the basis weight of the inner layer 11 is greater than or equal to 30 g / m³. 2 And less than or equal to 250g / m 2 For example, 30g / m 2 50g / m 2 70g / m 2 90g / m 2 100g / m 2 150g / m 2 200g / m 2 Or 250g / m 2 By controlling the weight of the inner layer 11 within the above-mentioned range, the inner layer 11 can have a good supporting effect, while its weight will not be too large.

[0051] In one embodiment, the functional section pipe fitting 10 has a two-layer pipe structure; the basis weight of the outer layer 12 is greater than or equal to 30 g / m³. 2 And less than or equal to 250g / m 2 For example, 30g / m 2 50g / m 2 70g / m 2 90g / m 2 100g / m 2 150g / m 2 200g / m 2 Or 250g / m 2 By controlling the weight of the outer layer 12 within the above-mentioned range, the outer layer 12 can have a good supporting effect, while its weight will not be too large.

[0052] In one embodiment, the functional segment pipe fitting 10 has a three-layer pipe structure, and the functional segment pipe fitting 10 further includes an intermediate layer 13 located between the inner layer 11 and the outer layer 12. The thickness of the inner layer 11 is greater than or equal to 0.033 mm and less than or equal to 0.267 mm, such as 0.033 mm, 0.05 mm, 0.1 mm, 0.20 mm, 0.25 mm, or 0.267 mm. Controlling the thickness of the inner layer 11 within the above range allows the inner layer 11 to have a good supporting effect, while its thickness is not too large.

[0053] In one embodiment, the functional segment pipe fitting 10 has a three-layer pipe structure, and the functional segment pipe fitting 10 further includes an intermediate layer 13 located between the inner pipe layer 11 and the outer pipe layer 12. The thickness of the outer pipe layer 12 is greater than or equal to 0.033 mm and less than or equal to 0.267 mm, such as 0.033 mm, 0.05 mm, 0.1 mm, 0.20 mm, 0.25 mm, or 0.267 mm. By controlling the thickness of the outer pipe layer 12 within the above range, the outer pipe layer 12 can have a good supporting effect, while its thickness is not too large.

[0054] In one embodiment, the functional segment pipe fitting 10 has a three-layer pipe structure, and the functional segment pipe fitting 10 further includes an intermediate layer 13 located between the inner layer 11 and the outer layer 12. The thickness of the intermediate layer 13 is greater than or equal to 0.033 mm and less than or equal to 0.267 mm, such as 0.033 mm, 0.05 mm, 0.1 mm, 0.20 mm, 0.25 mm, or 0.267 mm. By controlling the thickness of the intermediate layer 13 within the above range, the intermediate layer 13 can have a good supporting effect, while its thickness is not too large.

[0055] In one embodiment, the functional section pipe fitting 10 has a three-layer pipe structure, and the functional section pipe fitting 10 further includes an intermediate layer 13 located between the inner pipe layer 11 and the outer pipe layer 12. The basis weight of the inner pipe layer 11 is greater than or equal to 20 g / m³. 2 And less than or equal to 180g / m 2 For example, 20g / m 2 50g / m 2 70g / m 2 90g / m 2 100g / m 2 150g / m 2 Or 180g / m 2 By controlling the weight of the inner layer 11 within the above-mentioned range, the inner layer 11 can have a good supporting effect, while its weight will not be too large.

[0056] In one embodiment, the functional section pipe fitting 10 has a three-layer pipe structure, and further includes an intermediate layer 13 located between the inner pipe layer 11 and the outer pipe layer 12. The basis weight of the outer pipe layer 12 is greater than or equal to 20 g / m³. 2 And less than or equal to 180g / m 2 For example, 20g / m 2 50g / m 2 70g / m 2 90g / m 2 100g / m 2 150g / m 2 Or 180g / m 2 By controlling the weight of the outer layer 12 within the above-mentioned range, the outer layer 12 can have a good supporting effect, while its weight will not be too large.

[0057] In one embodiment, the functional section pipe fitting 10 has a three-layer pipe structure, and the functional section pipe fitting 10 further includes an intermediate layer 13 located between the inner pipe layer 11 and the outer pipe layer 12. The basis weight of the intermediate layer 13 is greater than or equal to 20 g / m³. 2 And less than or equal to 180g / m 2 For example, 20g / m 2 50g / m 2 70g / m 2 90g / m 2 100g / m 2 150g / m 2 Or 180g / m 2 By controlling the weight of the intermediate layer 13 within the above-mentioned range, the intermediate layer 13 can have a good supporting effect, while its weight will not be too large.

[0058] It should be noted that, regardless of whether the functional section pipe fitting 10 has a two-layer or three-layer structure, the thicknesses of the inner layer 11, the intermediate layer 13, and the outer layer 12 can be the same or different. The basis weights can also be the same or different.

[0059] In one embodiment, the thickness of the functional segment fitting 10 is greater than or equal to 0.10 mm and less than or equal to 0.80 mm. For example, 0.10 mm, 0.20 mm, 0.30 mm, 0.40 mm, 0.50 mm, 0.60 mm, 0.70 mm, or 0.80 mm. Controlling the thickness of the functional segment fitting 10 within the above range allows it to have good support while avoiding excessive thickness.

[0060] In one embodiment, please refer to Figure 2 The functional section pipe fitting 10 is a spiral wound pipe. That is to say, the functional section pipe fitting 10 is formed by spiral winding to form a spiral wound pipe.

[0061] Of course, in other embodiments, the functional segment fitting 10 can also be a structure formed using other processes.

[0062] For example, please see Figure 4 The functional section pipe fitting 10 is an overlap rolled pipe, which is formed by overlapping and rolling along the axial direction. As a result, it can achieve a better sealing effect.

[0063] In one embodiment, another embodiment of this application provides an aerosol generation system, which includes an aerosol generation device and an aerosol generation article as described in any embodiment of this application. The aerosol generation device includes a heating element for heating a matrix section 30 from the periphery to generate aerosol.

[0064] It should be noted that the heating element heats the substrate section 30 circumferentially from the outside (i.e., circumferential heating). In other words, the heating element is positioned around the aerosol-generating product to bake and heat the substrate section 30 from the outside in. The specific heating method can be resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc., and is not specifically limited here.

[0065] It should be noted that, regarding the peripheral heating method, since the outer periphery of the substrate section 30 is heated first, and the functional section tube 10 is in contact with the outer periphery of the substrate section 30, its heat transfer effect is more obvious, thus increasing the risk of generating paper impurities. However, in this embodiment, because the aerosol generation system uses the functional section tube 10 described in any embodiment of this application, the odor generated by the inner layer 11 and the outer layer 12 after heating is the same as the odor generated by the wrapping layer 20 after heating, thereby reducing impurities and improving the user's suction experience during the suction process.

[0066] Of course, in other embodiments, the heating element may also be the central heating matrix segment 30.

[0067] Preferably, in one specific embodiment, the functional segment tube 10 is in direct contact with the matrix segment 30. Therefore, the functional segment tube 10 receives better heat, but also carries a greater risk of generating paper impurities. Based on this, using the functional segment tube 10 described in any embodiment of this application can improve the reduction of paper impurities and significantly enhance the user's suction experience during the suction process.

[0068] In one specific embodiment, multiple sets of functional segment pipe fittings 10 of different materials and sizes are made into aerosol-generating products from conventional paper tubes, and sensory evaluation tests are conducted.

[0069] The functional section pipe fitting 10 in Example 1 is divided into three layers, from the outside to the inside: the outer layer 12 is 45g / m 2 The cigarette paper is 0.06mm thick. The middle layer 13 is 70g / m³. 2 The forming paper has a thickness of 0.10 mm. The inner layer 11 of the tube is 45 g / m². 2 The cigarette paper has a thickness of 0.06 mm. The functional section pipe fitting 10 is spirally rolled, and the resulting functional section pipe fitting 10 has a wall thickness of 0.22 mm.

[0070] The functional section pipe fitting 10 in Example 2 is divided into three layers, from the outside to the inside: the outer layer 12 is 60g / m 2 The tipping paper is 0.09mm thick; the middle layer 13 is 50g / m². 2 The sulfuric acid paper is 0.07 mm thick. The inner layer 11 of the tube is 60 g / m³. 2 The cork paper has a thickness of 0.09 mm. The functional section pipe fitting 10 is spirally wound, and the resulting functional section pipe fitting 10 has a wall thickness of 0.25 mm.

[0071] The functional section pipe fitting 10 in Example 3 is divided into three layers, from the outside to the inside: the outer layer 12 is 75g / m 2 The forming paper has a thickness of 0.11 mm; the intermediate layer 13 is 55 g / m². 2 The forming paper has a thickness of 0.09 mm. The inner layer 11 of the tube is 75 g / m². 2 The forming paper has a thickness of 0.11 mm. The functional section pipe fitting 10 is spirally wound, and the resulting functional section pipe fitting 10 has a wall thickness of 0.31 mm.

[0072] The functional section fitting for the comparative example is made of three layers of food-grade kraft paper, with a wall thickness of 0.30 mm. The aerosol-generating products of both the comparative example and the embodiment were heated using the same peripheral heating device, and the evaluation results are shown in Table 1 below.

[0073]

[0074] As can be seen from the results in Table 1, the sensory scores of the experimental group were all higher than those of the control group, and the papery smell was significantly improved compared with the control group, resulting in a better user experience when smoking.

[0075] When the functional section pipe fitting 10 adopts a two-layer pipe structure, its specific materials and dimensions can be set according to actual needs.

[0076] For example, the functional section pipe fitting 10 in Embodiment 4 is composed of two layers, from the outside to the inside: the outer layer 12 is a forming paper of 80g / m2 with a thickness of 0.12mm; the inner layer 11 is a forming paper of 120g / m2 with a thickness of 0.17mm. The functional section pipe fitting 10 is formed by a seam rolling process, and the resulting functional section pipe fitting 10 has a wall thickness of 0.22mm.

[0077] For example, the functional section pipe fitting 10 in Embodiment 5 is divided into two layers, from the outside to the inside: the outer layer 12 is 80g / m 2 The tipping paper is 0.11mm thick; the inner layer 11 is 70g / m². 2 The cork paper has a thickness of 0.10 mm. The functional section pipe fitting 10 is rolled by a lap joint process, and the wall thickness of the resulting functional section pipe fitting 10 is 0.22 mm.

[0078] In one specific embodiment, the aerosol generating article includes a plug 50, a matrix section 30, a functional section fitting 10, and a filter section 40 connected in sequence, and the aerosol generating article also includes a wrapping layer 20 covering the plug 50, matrix section 30, functional section fitting 10, and filter section 40. The plug 50 has a length of 6 mm, the matrix section 30 has a length of 12 mm, the functional section fitting 10 has a length of 20 mm, and the filter section 40 has a length of 10 mm.
