Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to an aerosol generation product. Background Technology

[0002] Heated non-combustible products are aerosol-generating products that produce smoke at low temperatures. Compared to regular cigarettes, they are less harmful because they do not burn and retain the taste of cigarettes, making them a better alternative to traditional cigarettes.

[0003] In related technologies, the smoke-generating materials for aerosol products sometimes use hygroscopic materials, which can easily absorb moisture during product transportation and storage, seriously affecting the smoke-generating effect, reducing the user experience, and even affecting normal use. Utility Model Content

[0004] This application provides an aerosol generating product that solves the technical problem of existing aerosol generating products easily absorbing moisture during transportation and storage. The aerosol generating product provided in this application includes a smoke-generating unit comprising plant material with hollowed-out cellular tissue and a smoke-generating medium. The smoke-generating medium, covering the outer surface of the plant material, is a gel film layer that effectively isolates the substances inside the smoke-generating unit from water molecules in the surrounding environment, making the smoke-generating unit less prone to moisture absorption and improving the user experience.

[0005] To address the aforementioned technical problems, some embodiments of this application provide an aerosol generating article comprising a particulate or filamentous smoke-generating unit. The smoke-generating unit includes plant material with hollowed-out cell tissue and a smoke-generating medium. Part of the smoke-generating medium fills the hollowed-out cell tissue, and part of the smoke-generating medium coats the outer surface of the plant material. The smoke-generating medium coating the outer surface of the plant material is a gel film.

[0006] In some embodiments, the plant material includes filamentous material cut from natural tobacco or natural non-tobacco plants, and / or, the plant material is puffed plant material.

[0007] In some embodiments, the smoke-generating medium is in the form of a solid gel at room temperature.

[0008] In some embodiments, the thickness of the gel film layer is ≤10μm.

[0009] In some embodiments, the content of the smoke-generating medium in the smoke-generating unit is 30% to 60%, and / or the filling rate of the plant material in the aerosol-generating article is less than 1.5 g / cm³. 3 .

[0010] In some embodiments, the smoke-generating medium comprises a polysaccharide-polyol smoke-generating agent mixed gel.

[0011] In some embodiments, the smoke-generating medium comprises a tamarind polysaccharide-polyol smoke-generating agent mixed gel.

[0012] In some embodiments, the aerosol generating article includes a smoke-generating material, the smoke-generating material including a plurality of smoke-generating units, the plurality of smoke-generating units being combined to form a porous smoke-generating matrix, and a continuous gel film layer being formed on the surface of the smoke-generating matrix.

[0013] In some embodiments, the aerosol generating article includes a smoke-generating material, the smoke-generating material including a plurality of the smoke-generating units; the aerosol generating article further includes a cylindrical package that encloses the smoke-generating units.

[0014] In some embodiments, the aerosol generating article further includes a cooling section disposed downstream of the smoke-generating material; and / or, the aerosol generating article further includes a sealing element disposed at one end of the smoke-generating material opposite to the cooling section; and / or, the aerosol generating article further includes a filtration section disposed downstream of the cooling section.

[0015] The aerosol generating product provided in this application includes granular or filamentous smoke-generating units. Each smoke-generating unit comprises plant material with hollowed-out cellular tissue and a smoke-generating medium. Part of the smoke-generating medium fills the hollowed-out cellular tissue, while another part coats the outer surface of the plant material. The smoke-generating medium coating the outer surface of the plant material forms a gel film, which acts as an isolation and protection layer. On the one hand, the gel film prevents the leakage of internal substances, thus improving the quality stability of the aerosol generating product during transportation and storage. On the other hand, the gel film significantly reduces the hygroscopicity and moisture absorption rate of the smoke-generating unit, ensuring its smoke-generating effect and effectively extending its shelf life.

[0023] The technical solution of this application will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by their components, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0024] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the order of the steps or actions in the method description can be changed or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0025] In some embodiments of this application, an aerosol generating article is provided. This aerosol generating article can be used in an aerosol generating device. When heated to a set temperature by the aerosol generating device, it can generate aerosols with specific plant material aromas and fragrances for users to inhale.

[0026] The aerosol-generating product includes granular or filamentous smoke-generating units. Each smoke-generating unit comprises plant material with hollowed-out cellular tissue and a smoke-generating medium. Part of the smoke-generating medium fills the hollowed-out cellular tissue, and part of the smoke-generating medium coats the outer surface of the plant material. The smoke-generating medium coating the outer surface of the plant material is a gel film.

[0027] The smoke-generating medium is in the form of a solid gel at room temperature.

[0028] The gel membrane layer serves as an isolation and protection layer. On the one hand, the gel membrane layer prevents the leakage of substances from the hollowed-out cellular tissues of the plant material, thus ensuring better quality stability of the aerosol-generated products during transportation and storage. On the other hand, the gel membrane layer also effectively isolates the substances inside the smoke-generating unit from water molecules in the surrounding air, making the smoke-generating unit less prone to moisture absorption, ensuring the smoke-generating effect of the unit, and effectively extending its shelf life.

[0029] In some embodiments, the plant material includes filamentous material cut from natural tobacco or natural non-tobacco plants.

[0030] Natural tobacco contains nicotine, and when processed into a smoke-generating unit, it can produce an aerosol with a specific aroma when burned or heated, which can then be inhaled by the user.

[0031] Natural non-tobacco plants can be used as a carrier for smoke generation. Natural non-tobacco plants can also be tobacco substitutes, selected from natural plants with specific aromas or tastes such as tea leaves, flowers, mint, licorice, rosemary, and fruits. After being processed into smoke-generating units, they can produce aerosols with specific aromas under combustion or heating conditions for users to inhale.

[0032] The smoke-generating unit provided in this embodiment may include only filamentous materials cut from natural tobacco, or only filamentous materials cut from natural non-tobacco plants, or filamentous materials cut from both natural tobacco and natural non-tobacco plants. In actual production, the appropriate selection can be made according to the actual needs of the aerosol-generated product. This application does not limit this.

[0033] In some embodiments, the plant material is a plant material that has undergone an expansion treatment to form a hollowed-out cell tissue, and the hollowed-out cell tissue is filled with the smoke-generating medium.

[0034] In some embodiments, the expansion rate of the plant material is not less than 200%, for example, the expansion rate of the plant material may be 200%, 205%, 210%, 225%, 240%, 280%, etc.

[0035] The higher expansion rate significantly increases the cavity volume of the hollowed-out cell tissue inside the expanded plant material, improving the plant material's absorption capacity for the smoke-generating medium. It can adsorb more smoke-generating medium containing smoke-generating agents, so the plant material can be added to aerosol-generating products with a relatively smaller filling amount, reducing the plant material cost of aerosol-generating products while ensuring sufficient aerosol volume.

[0036] In some embodiments, the smoke-generating medium includes a polysaccharide-polyol smoke-generating agent mixed gel, which is a mixed gel formed by the combination of polysaccharide and polyol smoke-generating agent through hydrogen bonding. For example, the polysaccharide-polyol smoke-generating agent mixed gel can be a mixed gel formed by combining plant polysaccharide solution, microbial polysaccharide solution, etc. with polyols such as glycerol and propylene glycol.

[0037] For example, the polysaccharide-polyol smoke generator mixed gel can be one or more of the following: tamarind polysaccharide-polyol smoke generator mixed gel, xanthan gum-polyol smoke generator mixed gel, seaweed polysaccharide-polyol smoke generator mixed gel, and pullulan polysaccharide-polyol smoke generator mixed gel. In this embodiment, the polysaccharide-polyol smoke generator mixed gel in the smoke generator unit can be one or more of the above-mentioned mixed gels, and this application does not limit this. In the final aerosol generating product, the smoke generator unit may or may not contain water.

[0038] When preparing aerosol-generating products from unexpanded plant materials, the plant materials are first pretreated. This pretreatment fills the hollowed-out cell tissues of the plant materials with a partial polysaccharide-polyol mixed gel, while a partial polysaccharide-polyol smoke-generating agent mixed gel adheres to the outer surface of the plant materials. The pretreated plant materials are then expanded and cured to create more and larger cavities within them. This allows for more thorough filling of the hollowed-out cell tissues by the smoke-generating medium and additives in subsequent processing steps, and promotes the continuous formation of the gel film on the outer surface of the plant materials. Figure 1 As shown, after pretreatment, expansion treatment, curing treatment, and subsequent treatments such as secondary application of polyol smoke-generating agent, polysaccharide solution, and additives, the plant material is finally subjected to alcohol treatment to obtain a smoke-generating unit with a continuous gel film layer on the outer surface.

[0039] When preparing aerosol-generating products using expanded plant materials as raw materials, the expanded plant materials can be pretreated, or they can be directly processed to allow the smoke-generating medium, additives, and other components to fill the hollowed-out cell tissues of the plant materials more fully. After the plant materials undergo alcohol treatment, a smoke-generating unit with a continuous gel film layer on its outer surface (such as...) can be obtained. Figure 1 (as shown in the image).

[0040] In the polysaccharide-polyol smoke agent mixed gel, the polysaccharide serves as the three-dimensional structural framework of the mixed gel and combines with the polyol smoke agent through hydrogen bonds to form a highly viscous mixed gel. The gel film layer formed by coating the outer surface of the plant material can form a complete coverage of the plant material, effectively isolating the internal substances of the plant material from the external environment. Thus, the gel film layer isolates the plant material from the external environment, prevents the leakage of internal substances, and reduces the moisture absorption and hygroscopic rate of the smoke-generating unit.

[0041] The polysaccharide-polyol fumigant mixed gel is solid at room temperature. Its freezing point can be lowered to below that of water by adjusting the ratio of polysaccharides, water, and polyols. Pretreated plant materials with hollowed-out cell tissues are filled with a large amount of this polysaccharide-polyol fumigant mixed gel. During expansion treatment, this allows the plant material to freeze at even lower temperatures. At the microscopic level, hydrogen bonds within the polysaccharide-polyol fumigant mixed gel can bind water molecules, causing them to exist in a monomolecular state. This increases the molecular surface area, and based on the principle of water expansion upon freezing, the ice crystals formed inside the plant material increase in volume, further increasing the specific surface area. Therefore, after the ice crystals sublimate, the plant material has more pores and a higher expansion rate. Therefore, based on the low freezing point of the polysaccharide-polyol fumigant mixed gel, the freezing temperature and freezing point during the expansion treatment of plant materials can be further reduced, significantly lowering the expansion treatment temperature. This allows solid water molecules in the plant materials at lower temperatures to expand to a greater extent and expand the cell tissue. After sublimation, these solid water molecules can create larger cell cavities and form more cavityd cell tissues in the plant materials, thereby increasing the expansion rate of the plant materials to over 200%. The higher the expansion rate of the plant materials, the more cavity structures and the larger the cavity volume of the internal cavityd cell tissues. This allows for more fumigating media and additives to fill the cavityd cell tissues of the plant materials during subsequent treatments, resulting in a better fumigation effect.

[0042] In some embodiments, the mass percentage of the smoke-generating medium in the smoke-generating unit is 30% to 60%, and the filling rate of the plant material in the aerosol-generating article is less than 1.5 g / cm³. 3 .

[0043] For example, the mass percentage of the smoke-generating medium in the smoke-generating unit can be 30%, 35%, 40%, 45%, 50%, 55%, 60%, etc.; the filling rate of the plant material can be 1.4 g / cm³. 3 1.2g / cm 3 0.9g / cm 3 0.5g / cm 3 wait.

[0044] The aerosol-generated product provided in this embodiment, based on the low freezing point characteristics of the polysaccharide-polyol mixed gel, fills the cavitary cell tissue of plant material with a smoke-generating medium. This significantly reduces the freezing temperature and freezing point of the plant material during the swelling process, allowing water in the plant material to have a larger volume after freezing during the swelling process. After the ice crystals sublimate during the solidification process, they can create more and larger cavitary structures inside the plant material, significantly increasing the expansion rate of the plant material. The formed cavity structure further promotes the filling of the smoke-generating medium in the cavitary cell tissue during subsequent processing, thereby increasing the mass percentage of the smoke-generating medium in the smoke-generating unit to 30%–60%, resulting in a better smoke-generating effect. Because the polyol smoke-generating agent and polysaccharide in the smoke-generating medium are bonded by hydrogen bonds to form a polysaccharide-polyol smoke-generating agent mixed gel with a lower freezing point, the temperature of the plant material swelling process is further reduced, and the expansion rate of the plant material is significantly increased. Consequently, the porosity is larger after expansion, reducing the plant material filling rate in the aerosol-generated product of this embodiment to 1.5 g / cm³. 3 The following not only reduces material costs, but also increases porosity due to a lower filling rate, which is conducive to the release of aerosols. It also produces more smoke and has a better smoke release effect. It can deliver better smoke production with relatively less plant material filling, thus improving the user's smoking experience.

[0045] In some embodiments, the smoke-generating unit further includes an additive, a portion of which fills the hollowed-out cell tissue and a portion of which coats the outer surface of the plant material.

[0046] Additives can be fragrance components applied to plant materials, including flavorings, added during the flavoring process of plant materials to enhance the taste and aroma of the smoke-generating unit. Flavorings can be selected from natural fragrance components, chemically synthesized fragrance components, or a mixture of natural and chemically synthesized fragrance components. This application does not limit this selection, as long as it meets the aroma requirements of the aerosol-generated product.

[0047] During the heating and smoke generation process of aerosol-generated products, the fragrance and flavor components in the additives are released outward along with the generated aerosols, providing users with a specific fragrance.

[0048] In some embodiments, the thickness of the gel film layer is ≤10μm, for example, it can be 10μm, 8μm, 6μm, etc.

[0049] In some embodiments, the smoke-generating medium comprises a tamarind polysaccharide-polyol smoke-generating agent mixed gel, wherein the tamarind polysaccharide-polyol smoke-generating agent mixed gel is formed by hydrogen bonding between a tamarind polysaccharide solution and a polyol smoke-generating agent, wherein the concentration of the tamarind polysaccharide solution can be set to 1-3%, for example, a 2% concentration tamarind polysaccharide solution can be selected, wherein the concentration of the polysaccharide solution is a mass percentage concentration.

[0050] The tamarind polysaccharide-polyol smoke agent mixed gel has a lower freezing point, making it easier to adhere to the outer surface of plant materials and form a continuous gel film. Furthermore, the lower freezing point allows the tamarind polysaccharide-polyol smoke agent mixed gel, filling the hollowed-out cell tissue of the plant material, to further reduce the swelling temperature and increase the volume of water condensing into ice during the swelling process. This results in more and larger hollowed-out cell tissue forming inside the plant material after solidification due to water sublimation, further increasing the mass percentage of smoke-generating media and additives in the smoke-generating unit.

[0051] In some embodiments, the mass ratio of glycerol to propylene glycol in the polyol smoking agent may be 5:1 to 1:1. For example, the mass ratio of glycerol to propylene glycol may be 5:1, 4:1, 3:1, 2:1, 1:1, etc.

[0052] Please see Figure 2 In some embodiments, the aerosol generating article includes a smoke-generating material, the smoke-generating material includes a plurality of smoke-generating units, the plurality of smoke-generating units are combined to form a porous smoke-generating matrix 1, and a continuous gel film layer is also formed on the surface of the smoke-generating matrix 1.

[0053] The aerosol generating product provided in this embodiment includes a smoke-generating material, which comprises multiple smoke-generating units. These units can be combined to form a smoke-generating substrate 1 with an externally unencased columnar structure, which is then inserted as a bare tobacco cartridge into a heated tobacco device with a mouthpiece for inhalation. The columnar structure can be cylindrical, regular, or irregular polygonal columnar; symmetry is not a limitation in this application, as long as it meets the tobacco cartridge usage requirements of the heated tobacco device.

[0054] Because the plant material surface of the smoke-generating unit is covered with a gel film layer, after multiple smoke-generating units are combined and formed, a continuous film-like gel film layer is also formed on the columnar outer surface of the smoke-generating substrate 1. These gel film layers form an isolation and protection effect on the smoke-generating units inside the smoke-generating substrate 1, preventing the substances inside the smoke-generating material from seeping out. This makes the smoke-generating substrate 1 have better quality stability during transportation and storage, and can also reduce the moisture absorption and hygroscopic rate of the smoke-generating substrate 1.

[0055] When the vapor-generating substrate 1, used as a bare e-cigarette cartridge, is heated to a certain temperature by the e-cigarette device (usually around 350°C), the polyol vapor-generating agent adsorbed on the plant material generates an aerosol upon heating. This aerosol carries specific plant fragrance components such as nicotine released from the plant material, as well as flavoring components released from polysaccharides and additives, mixing with air to form an aerosol for the user to inhale. During inhalation, the aerosol forms a condensate on the aerosol discharge end of the vapor-generating substrate 1. This condensate adsorbs particulate components from the aerosol, improving the quality of the aerosol produced and enhancing the vaping experience.

[0056] In addition, the aerosol-generating product provided in this embodiment has a higher expansion rate and lower addition amount of plant materials, which makes the smoke-generating matrix 1 have abundant pores. When heated, the aerosols and fragrances generated by the polyol smoke-generating agent and other components are more easily released to the outside through these pores, which can significantly improve the smoke generation and fragrance release effect of the smoke-generating unit and enhance the user's smoking experience.

[0057] Compared to traditional cigarettes that generate smoke through combustion and are then inhaled by the user, the aerosol-generated product provided in this embodiment releases specific plant aromas, additive aromas, and smoke from plant materials through low-temperature baking. This effectively reduces the release of harmful substances such as carbon monoxide and tar produced by the combustion of plant materials at high temperatures. Furthermore, the addition rate of plant materials in the smoke-generating matrix 1 is lower. Combined with the adsorption effect of condensate on particulate matter in the aerosol, the inhalation of harmful substances is further reduced, achieving the goal of harm reduction and benefiting the user's health.

[0058] Please see Figure 3 In some embodiments, the aerosol generating article includes a smoke-generating material, which comprises a plurality of smoke-generating units. The aerosol generating article also includes a cylindrical enclosure 2 that encloses the plurality of smoke-generating units. The enclosure 2 internally encloses the plurality of smoke-generating units of the smoke-generating material.

[0059] The aerosol-generating product made by enclosing multiple smoke-generating units in package 2 can be used directly as a cartridge. Compared to a bare cartridge where multiple smoke-generating units are directly combined to form a column, package 2 can provide storage and isolation protection for multiple smoke-generating units, preventing damage or leakage of multiple smoke-generating units due to external forces during transportation and storage. In addition, it can further reduce the moisture absorption rate of the smoke-generating units inside package 2, which is beneficial to improving the shelf life of the aerosol-generating product.

[0060] Please see Figure 4 In some embodiments, the aerosol generating article further includes a cooling section 20, which is located downstream of the smoke-generating material. Here, "downstream of the smoke-generating material" refers to the end from which the aerosol from the smoke-generating material is discharged during inhalation.

[0061] The cooling section 20 is used to cool down the aerosol generated by the smoke generating unit when it is heated, so as to prevent users from being burned by the high temperature aerosol when they inhale.

[0062] During the inhalation process, the aerosol generated by the smoke-generating unit in the smoke-generating section 10 has a certain temperature. The aerosol flows out from the mouth end of the aerosol product through the cooling section 20 to cool down the aerosol, ensuring the taste of the aerosol while preventing burns from high temperature.

[0063] In one embodiment, the wrapping element 2 can enclose a cooling material to form the porous cooling section 20, thereby cooling the aerosol using the enclosed cooling material. Alternatively, the corresponding wrapping element 2 of the cooling section 20 can also be a cavity, utilizing the cooling properties of fluid flowing through the cavity to achieve cooling of the aerosol. Alternatively, a cooling structure can also be provided inside the corresponding wrapping element 2 of the cooling section 20, for example, a baffle structure can be used to define a tortuous fluid passage path to extend the path length of the aerosol through the cooling section 20, thereby achieving cooling of the high-temperature aerosol.

[0064] Please see Figure 4 In some embodiments, the aerosol generating article further includes a sealing element 30, which is disposed at the end of the smoke generating unit facing away from the cooling section 20, i.e., the distal end of the smoke generating section 10. The sealing element 30 seals the distal end of the smoke generating section 10 to prevent the smoke generating unit in the smoke generating section 10 from falling off the distal end.

[0065] Please see Figure 4 In some embodiments, the aerosol generating article further includes a filter section 40, which is disposed downstream of the cooling section 20. Here, "downstream of the cooling section 20" refers to the end from which the aerosol is discharged after being cooled by the cooling section 20.

[0066] In some embodiments, the package 2 may wrap filter material to form a porous filter section 40, which is connected to the aerosol discharge end of the cooling section 20 to filter the cooled aerosol using the filter material and output the filtered aerosol.

[0067] The aerosol generating article provided in this application can be a smoke-generating matrix 1 formed by directly pressing multiple smoke-generating units into a columnar structure; it can also be a single-element cigarette structure consisting only of a smoke-generating section 10, formed by wrapping multiple smoke-generating units with a wrapping member 2; it can be a two-element cigarette structure formed by connecting the smoke-generating section 10 and the cooling section 20; it can be a three-element cigarette structure formed by connecting the smoke-generating section 10, the cooling section 20, and the filter section 40; it can also be a four-element cigarette structure formed by connecting the sealing member 30, the smoke-generating section 10, the cooling section 20, and the filter section 40. This application does not limit the scope of the application; it only needs to meet the actual usage requirements of the aerosol generating article.

[0068] The above examples illustrate the technical solution of this application only to aid in understanding its content and are not intended to limit the scope of this application. Those skilled in the art to which this application pertains can make several simple deductions, modifications, or substitutions based on the ideas presented in this application.
