Abstract
Description
Technical Field
[0001] The present application relates to the technical field of aerosol generation, and particularly relates to a particulate smoke medium, an aerosol product and an aerosol generation system. Background Art
[0002] The smoke media of heat-not-burn type have various forms, such as granular, strip-shaped, filamentous, paste-like and so on. The smoke substances inside these smoke media are basically evenly distributed. No matter which form of the smoke medium, it is usually difficult to match the energy of the heat-not-burn device, resulting in problems such as small smoke volume in the first few puffs and the last few puffs, and obvious attenuation of the taste, etc., and the puff-by-puff experience is inconsistent.
[0003] Currently, the above problems are mainly solved by improving the heat-not-burn device. For example, by increasing the output power of the heat-not-burn device, thereby raising the temperature curve and increasing the heating temperature, this can accelerate the rate of generating the smoke volume and overcome the problem of small smoke volume in the first few puffs. Although the smoke volume in the first few puffs increases significantly, however, at the back end of the heating process, the smoke substances of the smoke medium are quickly exhausted, resulting in a sudden decrease in the smoke volume in the last few puffs, obvious attenuation of the taste, and insufficient fragrance. Summary of the Utility Model
[0004] The present application provides a particulate smoke medium, an aerosol product and an aerosol generation system, aiming to solve the technical problems of inconsistent puff-by-puff experience such as small smoke volume in the first few puffs and the last few puffs, and obvious attenuation of the taste in the existing aerosol generation system.
[0005] According to a first aspect, in one embodiment, a particulate smoke medium is provided, which includes at least two smoke structure layers arranged in sequence from the center to the periphery, and in two adjacent smoke structure layers, the smoke structure layer located in the outer layer surrounds the smoke structure layer located in the inner layer;
[0006] Along the direction from the inside to the outside, the density of the smoke structure layer located in the outer layer in any two adjacent smoke structure layers is less than the density of the smoke structure layer located in the inner layer, so that the density of adjacent smoke structure layers decreases sequentially along the direction from the inside to the outside; or,
[0007] Along the direction from the inside to the outside, the density of the smoke structure layer located in the outer layer in any two adjacent smoke structure layers is greater than the density of the smoke structure layer located in the inner layer, so that the density of adjacent smoke structure layers increases sequentially along the direction from the inside to the outside.
[0008] In one embodiment, the density of adjacent smoke structure layers increases sequentially along the direction from the inside to the outside;
[0009] The granular smoke-generating medium further includes a heating element, which is located at the center of the innermost smoke-generating structure layer. Heat generated by the heating element is transferred from the inside to the outside.
[0010] In one embodiment, the density of the smoke-generating structural layer with the highest density among the at least two smoke-generating structural layers is a mg / mm 3 The value range of a is 3.5≤a≤4.5, and the density of the smoke-generating structure layer with the lowest density is b mg / mm 3 , the value range of b is 0.1≤b≤0.2.
[0011] In one embodiment, the average density of the particle-type smoke-generating medium is c mg / mm 3 , the value range of c is c≤4.
[0012] In one embodiment, the smoke-generating structure layer is provided with n layers, and the value range of n is 2≤n≤4.
[0013] In one embodiment, the granular smoke-generating medium is in a spherical or block shape.
[0014] In one embodiment, the granular smoke-generating medium is produced by at least one of wet granulation, dry granulation, spray granulation, melt granulation, and centrifugal granulation.
[0015] In one embodiment, each of the smoke-generating structure layers includes at least one of a tobacco material layer, an aromatic plant material layer, and a plant fiber material layer impregnated with a smoke-generating material.
[0016] According to the second aspect, an embodiment provides an aerosol product, comprising a smoking segment filled with a plurality of granular smoking media according to the first aspect.
[0017] In one embodiment, the average particle size of the granular smoke-generating medium in the smoke-generating section is no greater than 2.5 mm.
[0018] In one embodiment, the smoke-generating section includes at least two smoke-generating areas, and each of the smoke-generating areas contains a plurality of the granular smoke-generating media;
[0019] The average density of the granular smoke-generating media in the same smoke-generating area is the same, and the average density of the granular smoke-generating media in at least two different smoke-generating areas is different.
[0020] In one embodiment, the aerosol product further comprises at least one of a supporting section, a cooling section, and a filtering section.
[0021] According to a third aspect, in one embodiment, an aerosol generating system is provided, which includes a heat-not-burn device and the aerosol product described in the second aspect. At least the fuming section is adapted to be placed inside the heat-not-burn device;
[0022] The heat applied by the heat-not-burn device to the particulate fuming medium is transferred from the fuming structure layer with a lower density to the fuming structure layer with a higher density.
[0023] For the particulate fuming medium, aerosol product and aerosol generating system according to the above embodiments, by providing that the particulate fuming medium includes at least two fuming structure layers, and along the direction from the inside to the outside, the density of adjacent fuming structure layers of the particulate fuming medium decreases or increases in sequence, so that the particulate fuming medium has fuming structure layers with different densities, and the density of each fuming structure layer changes in sequence. Since the fuming structure layer with a lower density has a loose structure, by adapting the particulate fuming medium provided in this embodiment to the heat-not-burn device, when the energy is transferred from the fuming structure layer with a lower density to the fuming structure layer with a higher density, in the first few puffs, the heating component of the heat-not-burn device first quickly bakes out the loaded substances inside the fuming structure layer with a lower density, thus avoiding the problem of small fuming amount in the first few puffs; as the number of puffs increases, the temperature inside the entire fuming medium is relatively high, and compared with the first few puffs, the starting temperature of the heating component is relatively high, eliminating the process of the heating component itself and the fuming medium itself slowly warming up from room temperature. Later, as the heating component continues to heat, the loaded substances in the fuming structure layer with a higher density can be quickly baked out, avoiding the problem of poor fuming consistency of the fuming structure layer with a higher density after the fuming structure layer with a lower density is consumed. Since the fuming structure layer with a higher density has more loaded substances and a larger aerosol load, the fuming medium can continuously and stably emit smoke, avoiding the problem of small fuming amount in the last few puffs. Therefore, the particulate fuming medium provided in this embodiment can solve the problems of small fuming amount in the first few and last few puffs, obvious attenuation of taste, and inconsistent puff-by-puff experience, and improve the user experience.

The terms "connection" and "coupling" used in the present application, unless otherwise specified, both include direct and indirect connection (coupling).
[0036] Embodiment 1:
[0037] Please refer to Figure 1 , an embodiment of the present application provides a particulate smoke medium 10, which includes at least two smoke structure layers 11 arranged in sequence from the center to the periphery, and in two adjacent smoke structure layers 11, the smoke structure layer 11 located in the outer layer surrounds the smoke structure layer 11 located in the inner layer. Along the direction from the inside to the outside, the density of the smoke structure layer 11 located in the outer layer in any two adjacent smoke structure layers 11 is less than the density of the smoke structure layer 11 located in the inner layer, so that the density of adjacent smoke structure layers 11 decreases sequentially along the direction from the inside to the outside.
[0038] During use, the particulate smoke medium 10 cooperates with a heat-not-burn device, and the heat applied by the heat-not-burn device to the particulate smoke medium 10 is transferred from the low-density smoke structure layer 11 to the high-density smoke structure layer 11. The heating component of the heat-not-burn device is a circumferential heating element, that is, the heating component is located outside the particulate smoke medium 10, and the energy is transferred from the outside to the center of the particulate smoke medium 10, that is, from the low-density smoke structure layer 11 to the high-density smoke structure layer 11.
[0039] By adopting the above technical solution, by setting that the particulate smoke medium 10 includes at least two smoke structure layers 11, and along the direction from the inside to the outside, the density of the smoke structure layer 11 located in the outer layer in any two adjacent smoke structure layers 11 is less than the density of the smoke structure layer 11 located in the inner layer, so that the particulate smoke medium 10 has smoke structure layers 11 with different densities, and along the direction from the inside to the outside, the density of adjacent smoke structure layers 11 decreases sequentially.
[0040] When the density of the smoke structure layer 11 is smaller, its structure is looser, the substances carried are less, and the aerosol is more easily baked out; when the density of the smoke structure layer 11 is larger, its structure is tighter, the substances carried are more, and the aerosol loading is more.
[0041] By adapting the particulate aerosol-forming medium 10 provided in this embodiment to a heat-not-burn device, energy is transferred from the outside to the center of the particulate aerosol-forming medium 10. That is, when energy is transferred from the low-density aerosol-forming structure layer 11 to the high-density aerosol-forming structure layer 11, in the first few puffs, as soon as the heating component of the heat-not-burn device gives energy to the particulate aerosol-forming medium 10, since the low-density aerosol-forming structure layer 11 has a loose structure, the loaded substances therein are easily baked out, thus avoiding the problem of small aerosol generation in the first few puffs. As the number of puffs increases, the temperature inside the entire aerosol-forming medium is relatively high. At the same time, the low-density aerosol-forming structure layer 11 has been thoroughly baked. Subsequently, as the heating component continues to heat and the starting temperature is relatively high, the loaded substances in the high-density aerosol-forming structure layer 11 can be baked out. Moreover, since the high-density aerosol-forming structure layer 11 has more loaded substances and a large aerosol load, the aerosol-forming medium can continuously and stably generate aerosol, thus avoiding the problem of small aerosol generation in the last few puffs.
[0042] Therefore, the particulate aerosol-forming medium 10 provided in this embodiment can solve the problems of small aerosol generation in the first few and last few puffs, obvious taste attenuation, and inconsistent puff-by-puff experience, and improve the user experience.
[0043] In one embodiment, the density of the aerosol-forming structure layer 11 with the largest density among at least two aerosol-forming structure layers 11 is a mg / mm 3 , the value range of a is 3.5 ≤ a ≤ 4.5, and the density of the aerosol-forming structure layer 11 with the smallest density is b mg / mm 3 , and the value range of b is 0.1 ≤ b ≤ 0.2.
[0044] By setting the density of the aerosol-forming structure layer 11 with the largest density between 3.5 mg / mm 3 and 4.5 mg / mm 3 , the amount of substances loaded in this layer is sufficient and the amount of generated aerosol is also large enough to avoid the problem of small aerosol amount in the last few puffs. Specifically, during implementation, the density of the aerosol-forming structure layer 11 with the largest density can be set to 3.5 mg / mm 3 , 3.7 mg / mm 3 , 3.9 mg / mm 3 , 4.0 mg / mm 3 , 4.2 mg / mm 3 , 4.3 mg / mm 3 , 4.5 mg / mm 3 and so on. By setting the density of the aerosol-forming structure layer 11 with the smallest density between 0.1 mg / mm 3 and 0.2 mg / mm 3The structure is loose, and when the heating component of the heat-not-burn device just gives energy to the granular smoke-generating medium 10, the aerosol can be released quickly, avoiding the problem of small aerosol volume in the first few puffs. In specific implementation, the density of the smoke-generating structure layer 11 with the lowest density can be set to 0.1 mg / mm 3 , 0.12mg / mm 3 , 0.14mg / mm 3 , 0.16mg / mm 3 , 0.18mg / mm 3 , 0.2mg / mm 3 etc.
[0045] In one embodiment, the average density of the granular smoking medium 10 is c mg / mm 3 , the value range of c is c≤4. The average density of the granular smoke-generating medium 10 is the average density of all the smoke-generating structural layers 11. For example, the granular smoke-generating medium 10 has two layers of smoke-generating structural layers 11, and the density of one of the smoke-generating structural layers 11 is c1 mg / mm 3 The density of the other smoke-generating structure layer 11 is c2 mg / mm 3 , then the average density c of the particle-type smoke-generating medium 10 is equal to (c1+c2) / 2. In a specific implementation, the average density of the particle-type smoke-generating medium 10 can be set to 0.5 mg / mm 3 , 1mg / mm 3 , 1.5mg / mm 3 , 2mg / mm 3 , 2.5mg / mm 3 , 3mg / mm 3 , 3.5mg / mm 3 , 4mg / mm 3 etc.
[0046] In one embodiment, the smoke-generating structure layer 11 is provided with n layers, where n is in the range of 2≤n≤4. In a specific implementation, the smoke-generating structure layer 11 can be provided with 2, 3, or 4 layers. Of course, in other embodiments, the smoke-generating structure layer 11 can also be provided with at least 5 layers.
[0047] See also Figure 1 In this embodiment, the smoking structure layer 11 is provided with three layers: a first smoking structure layer 11a, a second smoking structure layer 11b, and a third smoking structure layer 11c, from the inside out. During use, heat is transferred from the third smoking structure layer 11c to the second smoking structure layer 11b, and then to the first smoking structure layer 11a.
[0048] In one embodiment, the granular smoking medium 10 is in a spherical or block shape.
[0049] In one embodiment, the particulate smoke medium 10 is made by at least one of the wet granulation method, dry granulation method, spray granulation method, melt granulation method, and centrifugal granulation method. Specifically in implementation, the manufacturing method of the particulate smoke medium 10 is not limited.
[0050] In one embodiment, each smoke structure layer 11 includes at least one of a tobacco material layer, an aromatic plant material layer, and a plant fiber material layer impregnated with a smoke material. Among them, the tobacco material layer is made of tobacco material, the aromatic plant material layer is made of aromatic plant material, and the plant fiber material layer impregnated with a smoke material is made of plant fiber material impregnated with a smoke material. Such a setting is to make each smoke structure layer 11 have a smoke material, that is, it can generate aerosol. Among them, the aromatic plant materials include but are not limited to fennel, cloves, star anise, and tea leaves.
[0051] In another embodiment, each smoke structure layer 11 includes at least one of a tobacco material, an aromatic plant material, and a plant fiber material impregnated with a smoke material, and the tobacco material, the aromatic plant material, and the plant fiber material impregnated with a smoke material can be mixed together in any way.
[0052] In one embodiment, each smoke structure layer 11 further includes at least one of an adhesive, an auxiliary agent, a pore-forming agent, and a flavor and fragrance. Among them, the adhesive includes but is not limited to carboxymethyl cellulose, sodium alginate, guar gum, and modified starch. The auxiliary agent can be a humectant, and the humectant includes at least one of malt oligosaccharide alcohol, D-galacturonic acid, chitosan derivative, propylene glycol, glycerol, sorbitol, and xylitol. The pore-forming agent is used for shaping, increasing particle hardness, pore formation and ventilation, etc., and can be calcium carbonate.
[0053] Embodiment 2:
[0054] The difference between the particulate smoke medium 10 provided in this embodiment and that in Embodiment 1 lies in the different structures of the particulate smoke medium 10. Specifically, in Embodiment 1, along the direction from the inside to the outside, the density of the smoke structure layer 11 located in the outer layer among any two adjacent smoke structure layers 11 is less than the density of the smoke structure layer 11 located in the inner layer; while in this embodiment, along the direction from the inside to the outside, the density of the smoke structure layer 11 located in the outer layer among any two adjacent smoke structure layers 11 is greater than the density of the smoke structure layer 11 located in the inner layer.
[0055] Please refer to Figure 2, in this embodiment, the density of adjacent smoke-generating structure layers 11 increases sequentially in the direction from the inside to the outside. Among them, the granular smoke-generating medium 10 further includes a heating element 12, and the heating element 12 is located at the center of the innermost smoke-generating structure layer 11, and the heat generated by the heating element 12 is transmitted in the direction from the inside to the outside. With this setting, when the heating element 12 starts to generate heat, the smoke-generating structure layer 11 with the smallest density located in the innermost layer can be heated first and can quickly release aerosol.
[0056] The heating element 12 is an induction heating element that can be heated without contact. Specifically, in implementation, electromagnetic heating or microwave heating or other methods can be used to heat the heating element 12 located at the center of the granular smoke-generating medium 10, so as to achieve the transmission of the heating element 12 from the inside to the outside.
[0057] Except for the above differences, the granular smoke-generating medium 10 and its components provided in this embodiment can be designed by referring to Embodiment 1, and will not be elaborated here.
[0058] Embodiment 3:
[0059] Please refer to Figure 3 , this embodiment provides an aerosol product 100, including a smoking section 101, and the smoking section 101 is filled with a plurality of granular smoke-generating media 10. Among them, the granular smoke-generating medium 10 can be the granular smoke-generating medium 10 provided in Embodiment 1, or can be the granular smoke-generating medium 10 provided in Embodiment 2.
[0060] By adopting the granular smoke-generating medium 10 provided in the above Embodiment 1 or 2, when the user uses the aerosol product 100, there are no problems such as small smoke output in the first few puffs and the last few puffs, obvious taste attenuation, and inconsistent per-puff experience, and the user's usage experience is good.
[0061] In one embodiment, the average particle size of the plurality of granular smoke-generating media 10 in the smoking section 101 is not greater than 2.5 mm. If the volume of the granular smoke-generating medium 10 is too large, it will cause a large gap between different granular smoke-generating media 10, and further result in a small amount of granular smoke-generating media 10 per unit volume of the aerosol product 100. By setting the average particle size of the plurality of granular smoke-generating media 10 to be not greater than 2.5 mm, the above situation is avoided, and the amount of granular smoke-generating media 10 per unit volume of the aerosol product 100 is effectively guaranteed. Specifically, the average particle size of the plurality of granular smoke-generating media 10 can be set to 0.5 mm, 0.8 mm, 1.0 mm, 1.3 mm, 1.6 mm, 2.0 mm, 2.2 mm, 2.5 mm, etc.
[0062] In one embodiment, each smoke-generating structure layer 11 of the particulate smoke-generating medium 10 includes at least one of tobacco material, aromatic plant material, and plant fiber material impregnated with a smoke-generating material. Among them, in an aerosol product 100, the total weight of the solid smoke-generating materials in all the tobacco materials, aromatic plant materials, and plant fiber materials impregnated with a smoke-generating material is 0.1 - 0.4 g / unit. In this way, the total amount of aerosol generated can be effectively ensured, and the use of excessive tobacco and other raw materials will not cause too high costs.
[0063] Embodiment 4:
[0064] The main difference between the aerosol product 100 provided in this embodiment and that in Embodiment 3 lies in the structure of the smoke-generating section 101. Specifically, in Embodiment 3, the smoke-generating section 101 is not divided into regions; while in this embodiment, the smoke-generating section 101 includes at least two smoke-generating areas 1011.
[0065] Please refer to Figure 4 , the smoke-generating section 101 includes at least two smoke-generating areas 1011. Each smoke-generating area 1011 contains multiple particulate smoke-generating media 10. The average density of the particulate smoke-generating media 10 within the same smoke-generating area 1011 is the same, and the average density of the particulate smoke-generating media 10 in at least two different smoke-generating areas 1011 is different.
[0066] During specific implementation, each smoke-generating area 1011 can be determined according to the temperature field distribution of the heat-not-burn device, and particulate smoke-generating media 10 with different average densities are matched in each smoke-generating area 1011. For example, the heat-not-burn device includes at least two heating areas, and the number of heating areas is the same as that of the smoke-generating areas 1011. Each heating area is disposed outside a corresponding smoke-generating area 1011 to heat the corresponding smoke-generating area 1011. In the first half of the puffing process, the temperature field is designed to supply high energy quickly to the smoke-generating area 1011 with a low average density to achieve rapid smoke generation; in the second half of the puffing process, the temperature field is designed to supply low energy to the smoke-generating area 1011 with a high average density, which is beneficial to the consistency of the taste and prevents the lack of substances being baked out in the second half, resulting in a rapid attenuation of the taste.
[0067] Except for the above differences, the aerosol product 100 and its components provided in this embodiment can be designed by referring to Embodiment 3, which will not be elaborated here.
[0068] Embodiment 5:
[0069] The main difference between the aerosol product 100 provided in this embodiment and those in Embodiments 3 and 4 lies in the structure of the aerosol product 100. Specifically, in Embodiments 3 and 4, the aerosol product 100 includes a smoke-generating section 101; while in this embodiment, the aerosol product 100 further includes at least one of a support section 102, a cooling section 103, and a filtering section 104.
[0070] Please refer to Figure 5 , the aerosol product 100 includes at least one of a support section 102, a cooling section 103, and a filtering section 104 and a smoking section 101. By providing the support section 102, it can support the smoking section 101 to prevent the smoking section 101 from moving under the action of other external components (such as the heating component of a heat-not-burn device), or the particulate smoking medium 10 in the smoking section 101 from shifting towards the filtering section 104. By providing the cooling section 103, it can cool the flowing aerosol to avoid scalding the user due to excessive temperature. By providing the filtering section 104, it can filter the flowing aerosol to remove impurities or harmful substances in the aerosol.
[0071] Except for the above differences, the aerosol product 100 and its components provided in this embodiment can be designed by referring to Embodiments III and IV, which will not be elaborated here.

At least the smoking section 101 is for being placed inside the heat-not-burn device 200; the heat applied by the heat-not-burn device 200 to the particulate smoking medium 10 is transferred from the low-density smoking structure layer 11 to the high-density smoking structure layer 11. Among them, the aerosol product 100 can be any one of the aerosol products 100 in Embodiments III to V.
[0074] During specific implementation, the aerosol product 100 is adapted to the heating component of the heat-not-burn device to avoid problems such as small smoke output in the first few puffs and the last few puffs, obvious attenuation of taste, and inconsistent puff-by-puff experience during the use of the aerosol generation system by the user, improving the user experience.
[0075] Please refer to Figure 6 and Figure 7 , the heat-not-burn device 200 is provided with a heating cavity 201 and a heating component 202.
