In a typical heated-without-combustion aerosol-generating product, it includes a medium section that volatilizes upon heating to generate an aerosol and a fragrance-carrying section disposed at one end of the medium section. The medium section is heated by an external heat source to a temperature sufficient to release the desired components and fragrance. The medium section does not burn; instead, it carries an atomizing agent, which is released through high-temperature heating during use to form an aerosol. In related technologies, the fragrance-carrying section has a relatively low fragrance content, reducing the user experience. Summary of the Invention

[0023] In one embodiment, the aerosol generating article further includes a filter section, and the fragrance-carrying section is disposed between the medium section and the filter section.

[0024] Thirdly, embodiments of this application provide a method for manufacturing a fragrance-carrying segment, the method comprising:

[0025] Fragrance substances are loaded onto the filler;

Furthermore, the filling portion being disposed within the wrapping layer to create a channel extending from one end of the fragrance-carrying segment to the other, allows the fragrance substance loaded on the filler material to be released into the channel upon heating. This mixture then mixes with the air and / or aerosol in the channel before being inhaled by the user, effectively reducing the suction resistance generated by the fragrance-carrying segment on the inhaled aerosol, further enhancing the user experience.

[0060] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0061] Please see Figures 1 to 5 In a first aspect, embodiments of this application provide an aerosol generating article 100, which includes a medium segment 20 and a fragrance-carrying segment 10 according to any embodiment of this application.

[0062] The aerosol-generating article 100 has a distal lip end 100a and a proximal lip end 100b.

[0063] It should be noted that, generally speaking, users can use the aerosol generating product 100 by holding it in their mouth. The proximal end 100b refers to the end of the aerosol generating product 100 that is closer to the user when using it, while the distal end 100a refers to the end of the aerosol generating product 100 that is farther away from the user when using it.

[0064] In this embodiment, the medium segment 20 is generally cylindrical. The cylindrical shape can be a cylinder (i.e., with a circular cross-section), a prism (i.e., with a polygonal cross-section), an elliptical cylinder (i.e., with an elliptical cross-section), etc., and is not limited thereto.

[0065] The aerosol generating article 100 is used in an aerosol generating apparatus having a receiving chamber, and the aerosol generating article 100 can be inserted into the receiving chamber and heated by the heating element of the aerosol generating apparatus.

[0066] The dielectric section 20 is used to generate aerosols. The heating element is used to convert electrical energy into heat energy, which acts on the dielectric section 20, and the dielectric section 20 can generate aerosols for user use after being heated.

[0067] The method by which the heating element heats the medium segment 20 is not limited. For example, the heating methods include center heating and peripheral heating. Center heating refers to the heating element being inserted into the medium segment 20 to bake and heat it from the inside out. Peripheral heating refers to the heating element being positioned around the medium segment 20 to bake and heat it from the outside in. These heating methods may specifically include resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc., and are not specifically limited here.

[0068] Please see Figures 1 to 5 The aerosol generating product 100 generally also includes an outer packaging layer 40, which surrounds the fragrance-carrying section 10 and the medium section 20.

[0069] The outer packaging layer 40 has a certain degree of hardness, which can provide some protection for the medium section 20, reduce the surface area of ​​the medium section 20 directly exposed to the outside world, thereby reducing the probability of the medium section 20 becoming damp and deteriorating due to contact with air. At the same time, it also reduces the probability of the medium section 20 coming into contact with other components in the aerosol generating device and causing pollution.

[0070] The specific material of the outer packaging layer 40 is not limited, such as one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, PBAT (Poly(butylene adipate-co-terephthalate)).

[0071] It should be noted that the specific location of the incense-carrying section 10 is not restricted here.

[0072] In some embodiments, the fragrance-carrying segment 10 is disposed at one end of the medium segment 20 and located at the distal lip end 100a of the aerosol generating article 100.

[0073] Thus, during use, the heat from the heated medium section 20 is conducted to the fragrance-carrying section 10, promoting the release of the fragrance substances it carries. During inhalation, these substances are pre-mixed with the cool outside air and then enter the medium section 20, mixing with the aerosol generated by the medium section 20. Furthermore, specific compounds can be added to the fragrance-carrying section 10, allowing these compounds to react with the medium section 20 to create a fragrance, making the aerosol fragrance more pleasant during inhalation. Moreover, on the one hand, the fragrance-carrying section 10 effectively reduces the chance of the medium section 20 falling out of the outer packaging layer 40 during use; on the other hand, after inhalation, the negative pressure generated during inhalation can cause aerosol backflow / recirculation in the container. The pleated filling has a good adsorption effect, adsorbing the aerosol during backflow / recirculation, which helps improve the problem of the container being contaminated by aerosols and difficult to clean, and also helps to mitigate the potential cross-contamination of flavors when inhaling different flavored aerosol-generated products 100.

[0074] In other embodiments, the aerosol generating article 100 further includes a filter section 32, and a fragrance-carrying section 10 is disposed between the medium section 20 and the filter section 32.

[0075] After being extracted in the medium section 20, the aerosol passes through the fragrance-carrying section 10. The heat inherent in the aerosol itself exchanges heat with the aroma-producing components in the fragrance-carrying section 10, causing the aerosol temperature to drop. Furthermore, this process allows the aroma-producing components to be released and mixed with the aerosol, improving the richness and consistency of the aroma within the aerosol. Simultaneously, in addition to its high aroma-carrying capacity, the fragrance-carrying section 10 also serves as a support and cooling mechanism.

[0076] The shape of the cross-section of the outer packaging layer 40 is not limited in a plane perpendicular to the axis of the aerosol-generating article 100. Generally, please refer to [link to relevant documentation]. Figure 5 The outer packaging layer 40 has a circular cross-section. Circular means that the outer packaging layer 40 has a wall thickness, therefore the cross-sectional shape of its inner and outer circumferential walls is circular. It can be understood that the outer packaging layer 40 is typically made of paper material with a relatively small thickness, for example, less than 1 mm; therefore, its cross-sectional shape can also be considered circular. In other words, the outer wall surface of the outer packaging layer 40 is cylindrical. With this structure, the outer packaging layer 40 and the aerosol generating product 100 are generally cylindrical in shape. This cylindrical aerosol generating product 100 can be inserted into the receiving chamber at various angles along its circumference, thus facilitating user operation.

[0077] Please see Figures 1 to 9 Secondly, embodiments of this application provide a fragrance-carrying segment 10, which is applied to an aerosol-generating product 100.

[0078] The fragrance-carrying segment 10 includes a wrapping layer 11 and a filling portion. The filling portion is formed by repeatedly bending a layered filling member 12, resulting in a pleated shape. The filling portion is disposed within the wrapping layer 11 to create a channel 10a extending from one end of the fragrance-carrying segment 10 to the other end within the wrapping layer 11. The filling member 12 is loaded with fragrance substances.

[0079] For example, the filler 12 loaded with fragrance material is embossed to obtain a pleated filling part;

[0080] Please see Figures 3 to 9 The filling part has a pleated shape, and the channel 10a extends along the axial direction of the fragrance-carrying section 10. It can be understood that the cross-section of the channel 10a is bent in a plane perpendicular to the axial direction of the fragrance-carrying section 10.

[0081] External airflow can flow through channel 10a to medium section 20, or the aerosol generated by medium section 20 can flow to channel 10a. This reduces the suction resistance of fragrance-carrying section 10 on the aerosol. Simultaneously, the pleated shape of the filling section provides better adsorption, thus improving the fragrance-carrying capacity of fragrance-carrying section 10 and reducing the likelihood of aerosol condensing and flowing downwards, remaining in the container of the aerosol generating device.

[0082] The filler 12 has a layered structure. The layered filler 12 is bent multiple times to form a pleated filling part, for example, by embossing.

[0083] The term "fragrance material loaded on filler 12" refers to the ability of the fragrance material to penetrate, be absorbed, or adhere to the surface of filler 12.

[0084] Of course, fragrance substances can also be loaded onto the filling part.

[0085] In related technologies, the low fragrance loading capacity of the fragrance-carrying segment reduces the user experience. Therefore, it is desirable to develop an aerosol-generating product with high fragrance loading capacity and the ability to effectively reduce the suction resistance of the fragrance-carrying segment on the aerosol.

[0086] In this embodiment, the fragrance-carrying segment 10 is composed of a wrapping layer 11 and a filling portion. The filling portion is formed by repeatedly bending a layered filler 12, resulting in a pleated shape. The filling portion is disposed within the wrapping layer 11 to create a channel 10a extending from one end of the fragrance-carrying segment 10 to the other end within the wrapping layer 11. Here, by setting the filling portion as a pleated structure formed by repeatedly bending a layered filler 12, the pleated filling portion has a better adsorption effect, which is beneficial to improving the fragrance-carrying capacity of the fragrance-carrying segment 10, thereby improving the fragrance richness and fragrance consistency in the aerosol, and ultimately improving the user experience. In addition, the filling part is disposed in the encapsulation layer 11 to form a channel 10a extending from one end of the fragrance segment 10 to the other end within the encapsulation layer 11. When the fragrance substance loaded on the filling member 12 is heated, it is released into the channel 10a and mixed with the air and / or aerosol in the channel 10a before being inhaled by the user. This can effectively reduce the suction resistance generated by the fragrance segment 10 on the inhaled aerosol and improve the user's user experience.

[0087] The fragrance-carrying segment 10 of this application embodiment is composed of a wrapping layer 11 and a filling part. The pleated filling part has a better adsorption effect, so that the fragrance-carrying segment 10 of this application embodiment can increase the fragrance-carrying capacity by 30% to 200% or more compared with the existing fragrance-carrying capacity. By controlling the setting position of the fragrance-carrying segment 10, the type of fragrance substance it carries, and the amount of fragrance substance added, the overall fragrance release consistency of the aerosol generating product 100 during the inhalation process can be improved, and the aerosol smoke temperature during the inhalation process can be reduced to a certain extent, thereby improving the overall inhalation experience for consumers.

[0088] The molding method of the media segment 20 is not limited. In some embodiments, the media segment 20 is a one-piece structure, that is, the media segment 20 is integrally molded. For example, the media segment 20 is a granular composite, also known as a powder composite, which is a reconstituted tobacco medium, such as a reconstituted tobacco medium containing smoke-generating agents, tobacco, and other components. The media segment 20 is an integral structure, for example, it can be molded into an integral structure by extrusion, injection molding, or die casting processes. Among them, extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the material is pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passed through the die at the extruder outlet to make products or semi-finished products of various cross sections. The media structure formed by extrusion molding is strip-shaped. In this way, the media segment 20 remains an integral medium after being heated and absorbed or after the heating stops, and it is not easy to disintegrate and fall off. This solves the problems of thin sheet, filament, or loose granular media segments 20 in the prior art, such as thin sheet loosening, filament component and granular component falling off, difficulty in cleaning, and uneven composition.

[0089] Of course, the medium segment 20 may not be a single-piece structure. For example, it can be disordered tobacco shreds (formed by directly cutting plant leaves into shreds), ordered sheet-like structures (formed by papermaking of plant leaf materials and other materials), or granular structures (formed by granulation of plant leaf materials and other materials).

[0090] The specific composition of the medium segment 20 is not limited here. For example, in some embodiments, the medium segment 20 may include plant ingredients, auxiliary ingredients, smoke-generating agents, adhesive ingredients, and fragrance ingredients, etc.

[0091] Plant-based ingredients are used to generate aerosols upon heating. Additive ingredients provide skeletal support for the plant-based ingredients. Smoke-generating ingredients produce smoke upon heating. Binder ingredients bind the various raw material components together. Flavoring ingredients provide characteristic aromas. Thus, the plant-based and smoke-generating ingredients ensure sufficient aerosol generation, while the flavoring ingredients enhance aroma release during inhalation, improving the user experience. Additive ingredients not only improve the flowability of the mixture but also create a porous structure in the medium section 20, facilitating aerosol extraction and flow. The binder ingredients ensure that the plant-based and additive ingredients form a stable mixture, preventing a loose structure.

[0092] For example, the plant-based ingredients can be one or more of the following: raw tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants, which are powdered after being crushed. The plant-based ingredients are the core source of the aroma, and the endogenous substances within them can provide users with a sense of physiological satisfaction. Endogenous substances, such as alkaloids, enter the bloodstream and promote the pituitary gland to produce dopamine, thereby achieving physiological satisfaction.

[0093] For example, the auxiliary components can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. The inorganic fillers include one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. Inorganic fillers provide skeletal support for the plant components and also have micropores, which can increase the porosity of the medium section 20, thereby increasing the aerosol release rate. Lubricants include one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase the flowability of the plant component powder, reduce the friction between the plant component powders, make the overall density of the plant component powder distribution more uniform, and also reduce the pressure required for extrusion molding, reducing die wear. Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can, to a certain extent, slow down the loss of aroma substances during storage, increase the stability of aroma substances, and improve the sensory quality of the product.

[0094] For example, the smoke-generating agent may include one or more combinations of: monohydric alcohols (such as menthol); polyhydric alcohols (such as propylene glycol, glycerol, triethylene glycol, 1,3-butanediol, and tetraethylene glycol); esters of polyhydric alcohols (such as triacetin, triethyl citrate, mixtures of diacetins, triethyl citrate, methylbenzyl benzoate, and triglyceride); monocarboxylic acids; dicarboxylic acids; polycarboxylic acids (such as lauric acid and myristic acid) or aliphatic esters of polycarboxylic acids (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, triacetin, mesoerythritol, mixtures of diacetins, diethyl octanoate, triethyl citrate, methylbenzyl benzoate, phenylacetic acid, ethyl vanillate, triglyceride, and lauryl acetate).

[0095] For example, the adhesive component achieves close contact with the component raw materials through wetting at the interface, generating intermolecular attraction, thereby binding the component raw materials, such as powders, liquids, etc. The adhesive component can be one or more combinations of natural plant extracts, non-ionic modified viscous polysaccharides, including tamarind polysaccharides, guar gum, and modified cellulose (such as carboxymethyl cellulose). The adhesive is used to bind particles together, preventing them from easily falling apart, and also improves the water resistance of the media segment 20, and is harmless to the human body.

[0096] For example, flavoring ingredients are used to provide characteristic aromas, such as hay, roasted sweetness, or solid or liquid substances of nicotine. Flavoring ingredients may include one or more combinations of tobacco or other plants, aromatic plant extracts, extracts, essential oils, and absolutes; flavoring ingredients may include one or more combinations of monomeric aroma substances, such as megastigmatrienone, neophytadiene, geraniol, nerol, etc.

[0097] It should be noted that the cross-sectional shape of the incense-carrying section 10 is not limited here.

[0098] In some embodiments, please refer to Figures 5 to 8 On a plane perpendicular to the axial direction of the incense-carrying section 10, the cross-section of the incense-carrying section 10 is circular.

[0099] In other embodiments, please refer to Figure 9 On a plane perpendicular to the axial direction of the incense-carrying section 10, the cross-sectional shape of the incense-carrying section 10 is non-circular.

[0100] As can be seen from the foregoing, on a plane perpendicular to the axial direction of the fragrance-carrying section 10, the outer packaging layer 40 is generally annular, while the cross-sectional shape of the fragrance-carrying section 10 is non-circular. Therefore, after the fragrance-carrying section 10 and the outer packaging layer 40 are assembled, an outer peripheral airway can be defined between the inner sidewall of the outer packaging layer 40 and the outer sidewall of the wrapping layer 11.

[0101] The external airflow can flow to the medium section 20 through the peripheral air passage, thereby reducing the suction resistance of the fragrance section 10 to the aerosol, which is beneficial to improving the user experience.

[0102] In addition, the peripheral airway is formed on the periphery of the fragrance-carrying section 10. After the external airflow flows through the peripheral airway to the medium section 20, it can gradually flow from the periphery of the medium section 20 to the interior. This process can increase the utilization rate of the periphery of the medium section 20, thereby improving the suction performance of the aerosol-generating product 100.

[0103] In one embodiment, the fragrance substance includes at least one of natural plant extracts, fragrance raw material reactants, fragrance flavorings, and fragrance powders.

[0104] Here, flavor raw material reactants refer to some of the reactants in flavorings, including Maillard reaction, tobacco pyrolysis products, etc.

[0105] The fragrance substance is loaded onto the filler 12. After being heated, the fragrance substance detaches from the filler 12 and then mixes with the aerosol generated by the medium section 20, thereby increasing the fragrance richness in the aerosol.

[0106] In one embodiment, the weight ratio of the fragrance substance to the filler 12 is greater than or equal to 0.1‰wt and less than or equal to 80%wt. Examples include 0.1‰, 1%wt, 5%wt, 10%wt, 15%wt, 20%wt, 25%wt, 30%wt, 35%wt, 40%wt, 45%wt, 50%wt, 55%wt, 60%wt, 65%wt, 70%wt, 75%wt, 80%wt, etc.

[0107] Here, by setting the filling part to a pleated shape, the ratio of the weight of the fragrance substance loaded on the filling member 12 to the weight of the filling member 12 can be greater than or equal to 0.1‰wt and less than or equal to 80%wt, so that the filling part has a high fragrance carrying capacity.

[0108] When the weight of the flavoring substance is less than 0.1‰wt, the added flavor components result in poor consistency of aroma release during inhalation, reducing the user experience. When the weight of the flavoring substance is greater than 80‰, the required component is higher, and the overall consistency during inhalation is poor. Therefore, a flavoring substance weight of 0.1‰ to 80% is suitable. Preferably, the flavoring substance weight is 10‰ to 60%.

[0109] In one embodiment, the material of the wrapping layer 11 includes at least one of broadleaf fiber, softleaf fiber, hemp fiber, and bamboo fiber.

[0110] On the one hand, the coating layer 11 of this material has a certain toughness, which allows it to be wound around the filling part to obtain the fragrance segment 10; on the other hand, the coating layer 11 of this material also has a certain strength, which can reduce the probability of deformation of the fragrance segment 10, thus helping to improve the yield of the fragrance segment 10.

[0111] In addition, the wrapping layer 11 made of fiber paper will not melt or condense when heated, and the fragrance-carrying section 10 is not prone to deformation or collapse, thereby reducing the probability of blockage of the channel 10a inside the fragrance-carrying section 10 and thus improving the problem of changes in suction resistance during the suction process.

[0112] In one embodiment, the thickness of the wrapping layer 11 ranges from 0.05 mm to 0.5 mm. For example, it can be 0.05 mm, 0.1 mm, 0.15 mm, 0.18 mm, 0.2 mm, 0.25 mm, 0.27 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.46 mm, or 0.5 mm, etc.

[0113] When the thickness of the wrapping layer 11 is less than 0.05mm, the wrapping layer 11 is weak due to its low thickness, making it prone to deformation after wrapping the internal filling part. This also leads to weak processing capability of the fragrance-carrying segment 10 and a decrease in yield. When the thickness of the wrapping layer 11 is greater than 0.5mm, the thickness at the joint after molding is large (the joint is where the beginning and end of the wrapping layer 11 overlap), resulting in a poor appearance of the fragrance-carrying segment 10 at the joint. Therefore, by setting the thickness of the wrapping layer 11 to 0.05mm-0.5mm, the wrapping layer 11 can have a certain degree of toughness and strength while helping to improve the problem of large thickness at the joint.

[0114] In one embodiment, the diameter of the fragrance-carrying segment 10 is d, and the width of the wrapping layer 11 is greater than or equal to πd+0.5mm and less than or equal to πd+3mm.

[0115] When the width of the wrapping layer 11 is less than πd + 0.5 mm, the overlapping area at the connection / overlap of the beginning and end of the wrapping layer 11 is short, making processing difficult and resulting in low strength at the connection / overlap after formation, making it prone to cracking. When the width of the wrapping layer 11 is greater than πd + 3 mm, the overlapping area at the connection / overlap of the beginning and end of the wrapping layer 11 is long, making it prone to "curling" during processing, leading to a decrease in the pass rate during production.

[0116] Therefore, by setting the width of the wrapping layer 11 to be greater than or equal to πd+0.5mm and less than or equal to πd+3mm, the overlapping area at the connection / overlap of the beginning and end of the wrapping layer 11 can be appropriately arranged, so that the connection / overlap of the beginning and end of the wrapping layer 11 has sufficient strength. At the same time, it can also improve the "curling" phenomenon at the connection / overlap of the beginning and end of the wrapping layer 11 and improve the production qualification rate of the fragrance-carrying section 10.

[0117] Preferably, the diameter of the fragrance-carrying segment 10 is d, and the width of the wrapping layer 11 is greater than or equal to πd+1mm and less than or equal to πd+2mm.

[0118] The material of filler 12 is not limited. For example, it can be various types of paper.

[0119] In related technologies, the filler is made of polymer materials such as PLA (polylactic acid), PET (polyethylene glycol terephthalate), and CA (cellulose acetate). During use, the fragrance-carrying section is prone to melting, condensation, and collapse upon contact with the heating element. This blockage of the channels within the fragrance-carrying section hinders airflow to the medium section for aerosol extraction. Consequently, the suction resistance of the aerosol-generated product increases significantly during suction, and chemical impurities are generated, negatively impacting the user experience. Furthermore, fragrance-carrying sections made from the aforementioned polymer materials have a low loading capacity for fragrance substances and can only load fat-soluble fragrance substances, resulting in a limited variety of fragrance substances that can be carried by the fragrance-carrying section.

[0120] The paper-based filler 12 can operate normally at temperatures below 420°C, while the heating temperature of typical aerosol generating devices is 200–320°C. Therefore, the filler 12 is less prone to melting or condensation when in contact with the heating element, reducing the likelihood of blockage in the channels 10a within the fragrance-carrying section 10. This avoids a significant increase in suction resistance during extraction, and the paper does not produce a chemical odor when heated. Furthermore, the paper-based filler 12 has good adsorption properties. Folding the paper-based filler 12 into a pleated shape further enhances its adsorption effect, improving its adsorption performance for aerosols during backflow / reverse flow. Moreover, the paper-based filler 12 has a high loading capacity for fragrance substances and can hold different types of fragrance substances, allowing the fragrance-carrying section 10 to hold a wider variety of fragrance substances, further enriching the fragrance content of the aerosol.

[0121] In one embodiment, the filler 12 is made of fiber paper or non-woven fabric.

[0122] The filler 12, made of fiber paper, gives the fragrance-carrying section 10 better filling strength, which can improve the production qualification rate of the product during subsequent processing. At the same time, it can also improve the connection strength between the fragrance-carrying section 10 and the medium section 20, and improve the problems of bending and breakage of the aerosol-generated product 100 caused by insufficient connection strength during use.

[0123] In one embodiment, the weight range of the filler 12 is 20 g / m³. 2 -140g / m 2 For example, it could be 20g / m³. 2 30g / m 2 40g / m 2 50g / m 2 60g / m 2 70g / m 2 80g / m 2 90g / m 2 100g / m 2 110g / m 2 120g / m 2 130g / m 2 140g / m 2 etc.

[0124] It should be noted that when the basis weight of filler 12 is low, its processing performance is low, resulting in a relatively low yield of fragrance segment 10. When the basis weight is high, the paper impurities generated by filler 12 are heavier during subsequent use, affecting the user's experience.

[0125] In this embodiment, the weight of filler 12 is controlled at 20 g / m³. 2 -140g / m 2 Within this range, it is possible to minimize the generation of paper impurities while ensuring the processing performance of the fiber paper. In other words, it is possible to ensure the yield of the fragrance-carrying segment 10 while also taking into account the user experience.

[0126] In one embodiment, the basis weight of the encapsulation layer 11 is in the range of 25 g / m³. 2 -100g / m 2 For example, it could be 25g / m³. 2 30g / m 2 40g / m 2 50g / m 2 60g / m 2 70g / m 2 80g / m 2 90g / m 2 100g / m2 etc.

[0127] It should be noted that when the basis weight of the wrapping layer 11 is low, its processing performance is low, resulting in a relatively low yield of the fragrance-carrying segment 10. When the basis weight is high, the paper impurities generated by the filler 12 are heavier during subsequent use, affecting the user's experience.

[0128] In this embodiment, the weight of the wrapping layer 11 is controlled at 20 g / m². 2 -140g / m 2 Within this range, it is possible to minimize the generation of paper impurities while ensuring the processing performance of the fiber paper. In other words, it is possible to ensure the yield of the fragrance-carrying segment 10 while also taking into account the user experience.

[0129] For example, please refer to Figure 10 and Figure 11 The filler 12 includes a base layer 121 and a hardening layer 122 stacked together.

[0130] In other words, the filler 12 is a composite material. It uses paper as the base layer 121, and after the hardening layer 122 is applied to the base layer 121 and dried, it becomes high-strength fiber paper.

[0131] The base layer 121 is made of paper material, which makes it less prone to melting and shrinkage. A hardening layer 122 is provided on the base layer 121, which can improve the structural strength of the filler 12 and thus improve the production qualification rate of the product in subsequent processing.

[0132] In addition, the filler 12 with this structure can improve the connection strength between the fragrance section 10 and the medium section 20, and improve the problems of bending and breaking of the aerosol product 100 caused by insufficient connection strength during use. Moreover, during the heating process, the fiber impurities generated by the base layer 121 can be blocked by the hardened layer 122, and the fiber impurities can be confined inside the filler 12, thereby improving the user experience.

[0133] In one embodiment, the substrate 121 is made of at least one of broadleaf fiber, softleaf fiber, hemp fiber, and bamboo fiber.

[0134] Broadleaf fiber, softleaf fiber, hemp fiber, and bamboo fiber are all natural or extracted products, with relatively abundant raw materials, which facilitates the large-scale production of the base layer 121. At the same time, the base layer 121 made of such materials is biodegradable after use, making it more environmentally friendly.

[0135] In one embodiment, the hardening layer 122 is formed by coating a mixture of a hardening material and a solvent onto the surface of the base layer 121. The hardening material includes at least one of cellulose, polysaccharides, polylactic acid, butylene terephthalate, and polyethylene terephthalate.

[0136] Specifically, one or more of the following materials are used as base materials: cellulose, polysaccharides, polylactic acid, butylene terephthalate, and polyethylene terephthalate. They are then mixed uniformly in appropriate proportions according to the target requirements to obtain a hardened material.

[0137] The solvent is a mixture of one or more of the following: water, ethanol, glycerol, etc.

[0138] A homogeneous mixture is obtained by mixing the hardening material with a solvent. It is understood that the hardening material and solvent can be mixed in one or more batches.

[0139] After the hardened layer 122 is coated on the surface of the base layer 121, the filler 12 can be obtained by heating, air drying and other processes, thereby improving the structural strength of the filler 12. The hardened layer 122 can also block the fiber impurities generated by the base layer 121, so as to confine the fiber impurities inside the filler 12, thereby improving the user experience.

[0140] For example, please refer to Figure 10 and Figure 11 The number of base layer 121 and hardening layer 122 is one; or, the number of base layer 121 is one, the number of hardening layer 122 is two, and the two hardening layers 122 are respectively stacked on both sides of the base layer 121 along the thickness direction.

[0141] It should be noted that whether the hardened layer 122 is coated on one side of the base layer 121 along its thickness direction or on both sides can be determined based on the required strength of the filler 12. That is, coating the base layer 121 with the hardened layer 122 on both sides along its thickness direction results in higher strength of the filler 12; if the hardened layer 122 is coated on only one side of the base layer 121 along its thickness direction, the filler 12 will meet the strength requirements, and the other side will not need to be coated with the hardened layer 122, which helps to control costs.

[0142] Furthermore, when the base layer 121 is made of low-lignin fibers such as cotton or linen, the base layer 121 itself can generate less fiber impurities, so a single-layer coating of the hardening layer 122 is sufficient to improve the strength of the filler 12. When the base layer 121 is made of medium- or high-lignin fiber paper such as broadleaf or softleaf fibers, the base layer 121 itself can generate more fiber impurities. Therefore, a hardening layer 122 can be coated on both sides of the base layer 121 along its thickness direction. This not only improves the strength of the filler 12 but also reduces the release of fiber impurities, thus confining the fiber impurities inside the filler 12 and improving the user experience.

[0143] In other embodiments, the filler 12 does not have a hardening layer 122; that is, the filler 12 serves as the base layer 121. In this embodiment, while the filler 12 has a certain structural strength, it also helps to improve the fragrance-carrying capacity of the fragrance-carrying segment 10. In this case, the material of the filler 12 includes at least one of broadleaf fiber, softleaf fiber, hemp fiber, and bamboo fiber.

[0144] In one embodiment, the maximum distance between two points on the outer periphery of the cross section of the fragrance-carrying section 10 on a plane perpendicular to the axial direction of the fragrance-carrying section 10 is d.

[0145] It should be noted that the incense-carrying section 10 is matched with a cylinder, and the incense-carrying section 10 is placed inside the cylinder. By shrinking the diameter of the cylinder until the incense-carrying section 10 can no longer make horizontal displacement within the cylinder, the diameter of the inner circle of the cylinder at this point is d as mentioned above. For example, for an incense-carrying section 10 with an elliptical cross-sectional shape, d is the major axis of the ellipse; for an incense-carrying section 10 with a rectangular cross-sectional shape, d is the dimension of the diagonal line connecting the two sides of the rectangle.

[0146] For example, the fragrance-carrying segment 10 is cylindrical and has a diameter of d.

[0147] In some embodiments, please refer to Figure 5 and Figure 6 The number of filler elements 12 is one, and the width of filler element 12 ranges from 2d to 60d. For example, it can be 2d, 5d, 8d, 11d, 14d, 17d, 20d, 23d, 26d, 29d, 32d, 35d, 38d, 41d, 44d, 47d, 50d, 53d, 56d, 59d, 60d, etc.

[0148] It should be noted that, in a plane perpendicular to the axial direction of the incense-carrying section 10, the cross-section of the filler 12 presents as a continuous line (e.g., Figure 5 As shown), the width of filler 12 is the total length of the line.

[0149] It should be noted that "2d" refers to a width of 2 times d, and "60d" and so on can be understood in the same way, that is, "60d" refers to a width of 60 times d.

[0150] In this embodiment, on the one hand, the width of the filler 12 is not less than 2d, thereby ensuring that the wrapping layer 11 has sufficient filling and reducing the probability of the filler 12 falling out of the wrapping layer 11, which is conducive to ensuring the user's user experience; on the other hand, the width of the filler 12 is not greater than 60d, that is, it will not cause the wrapping layer 11 to have excessive filling, thereby effectively controlling the suction resistance of the fragrance segment 10.

[0151] In addition, when paper is used to manufacture the filler 12, the problem of excessive paper material used in the fragrance section 10 will not occur. During user use, it can effectively improve the problems of heavy paper impurities in the aerosol product 100 and poor user experience.

[0152] In other embodiments, there are multiple filler elements 12, and the sum of the widths of each filler element 12 ranges from 2d to 60d. For example, they can be 2d, 4d, 7d, 10d, 13d, 16d, 19d, 22d, 25d, 28d, 31d, 34d, 37d, 40d, 46d, 50d, 53d, 57d, 60d, etc.

[0153] For example, when there are multiple fillers 12, each filler 12 is bent to form a whole, that is, each layered filler 12 is bent multiple times to form a pleated shape, for example, the filler 12 is embossed to form a pleated shape, and then multiple bent fillers 12 are stacked to form a filling part (e.g. Figure 7 (As shown). Alternatively, multiple filler elements 12 can be stacked together, with the overall thickness of the stacked filler elements 12 being larger than the thickness of a single filler element 12. The stacked filler elements 12 can then be bent multiple times to form a pleated filling section (e.g., Figure 8 (As shown).

[0154] In this embodiment, on the one hand, the sum of the widths of each filler 12 will not be less than 2d, thereby ensuring that the wrapping layer 11 has sufficient filling amount and reducing the probability of the filler 12 falling out of the wrapping layer 11, which is conducive to ensuring the user's user experience; on the other hand, the sum of the widths of each filler 12 will not be greater than 60d, that is, the wrapping layer 11 will not have the problem of excessive filling amount, thereby effectively controlling the suction resistance of the fragrance segment 10.

[0155] Furthermore, when multiple fillers 12 are used, each filler 12 needs to be connected to the wrapping layer 11. Compared to a single filler 12, the number of connection end faces between the wrapping layer 11 and the filler 12 increases. In subsequent processing, such as during the slitting process, the filler 12 is prone to detach from the wrapping layer, resulting in a lower pass rate and increased production costs.

[0156] To confirm whether you want to select one or multiple fillers 12, please refer to the following:

[0157] It should be noted that the greater the compressibility, the better the elastic deformation performance of the filler 12, and the more it can recover its original shape after use.

[0158] The compressibility (cross-sectional area deformation ratio) of the filler 12 during use is determined based on its compressibility. When the compressibility of the filler 12 during use is greater than 0.75, although the internal hardened layer 122 is relatively hard, it can still shrink according to the usage environment and recover its shape after use, ensuring the consistency of the product's appearance before and after use. When the compressibility of the filler 12 during use is less than 0.75, if a single base layer 121 is still used, it will cause the filler 12 to undergo plastic deformation. Therefore, when the compressibility of the filler 12 during use is less than 0.75, multiple fillers 12 of the same specification or multiple fillers 12 of different specifications consisting of base layers 121 and hardened layers 122 can be used for molding to ensure the consistency of the filler 12's appearance before and after use, which is beneficial to improving the user experience.

[0159] In some embodiments, please refer to Figure 7 There are multiple fillers 12, and at least some of the fillers 12 are loaded with different fragrance substances.

[0160] Here, "at least some of the fillers 12 have different fragrance substances" means that the fragrance substances loaded on each filler 12 are different, or that the fragrance substances loaded on some of the fillers 12 are different.

[0161] Thus, when blending compound fragrances, if the fragrance components have poor miscibility or significant differences in fragrance form, different fragrance substances can be added to different fillers 12, which helps to prolong the release and improve the inhalation experience of the aerosol fragrance.

[0162] Of course, in other embodiments, the fragrance substance loaded on each filler 12 may also be the same.

[0163] In one embodiment, the filler 12 has a fill rate in the encapsulation layer 11 ranging from 10% to 98%. For example, it can be 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 98%, etc.

[0164] Filling rate = ((sum of widths of each filler component × filler component thickness) - (width of the wrapping layer × thickness of the wrapping layer)) / cross-sectional area of ​​the fore-end section.

[0165] Please see Figures 2 to 4 The sum of the widths of each filler and the thickness of the filler refer to the sum of the cross-sectional areas of each filler 12 on a plane perpendicular to the axial direction of the aerosol-generating product 100.

[0166] It is understandable that when there is only one filler 12, the cross-sectional area of ​​one filler 12 is the sum of the cross-sectional areas of all fillers 12.

[0167] Please see Figures 2 to 4 The width of the coating layer × the thickness of the coating layer refers to the cross-sectional area of ​​the coating layer 11 on a plane perpendicular to the axial direction of the aerosol generating product 100.

[0168] Please see Figures 2 to 4 The cross-sectional area of ​​the front plug section refers to the cross-sectional area of ​​the area enclosed by the outer wall of the wrapping layer 11 on a plane perpendicular to the axial direction of the aerosol generating product 100.

[0169] Alternatively, the fill rate = (sum of widths of each filler element × filler element thickness) / cross-sectional area of ​​the area enclosed by the inner wall of the wrapping layer.

[0170] Please see Figures 2 to 4 The cross-sectional area of ​​the region enclosed by the inner wall of the coating layer refers to the cross-sectional area of ​​the region enclosed by the inner wall of the coating layer 11 on a plane perpendicular to the axial direction of the aerosol generating product 100.

[0171] The specific value of the fill rate can be selected according to the requirements.

[0172] It should be noted that when the filling rate is too low, the fragrance segment 10 has low strength during use, and the aerosol product 100 is prone to deformation and breakage during the suction process, which reduces the user experience; when the filling rate is too high, the fragrance segment 10 has high suction resistance during the suction process, which is not conducive to the user's suction of aerosol.

[0173] In this embodiment, the fragrance-carrying segment 10 has a filling rate controlled within the range of 10%-98%. The fragrance-carrying segment 10 has high structural strength and does not generate too much suction resistance.

[0174] Preferably, the filler 12 has a fill rate of 25%-90% within the wrapping layer 11.

[0175] It should be noted that the aroma-carrying section 10 can be set according to the release temperature of the aroma substances. The high-temperature zone corresponds to the high-volatility temperature aroma substances, and the low-temperature zone corresponds to the low-volatility temperature aroma substances. This can prolong the release time of the aroma substances, thereby improving the consistency of the smoke.

[0176] In one embodiment, please refer to Figures 1 to 4 The aerosol generating product 100 also includes a basic structure section 30, which is located at the end of the medium section 20 away from the fragrance-carrying section 10. The basic structure section 30 includes at least one of a support section 31, a filter section 32, and a cooling section 33.

[0177] Specifically, such as Figure 2 As shown, the basic structure section 30 includes a support section 31, a cooling section 33, and a filter section 32. The fragrance-carrying section 10 is located at the distal lip end 100a of the aerosol generating product 100. The support section 31 is located at one end of the medium section 20 along the axial direction, one end of the cooling section 33 is located at the end of the support section 31 away from the medium section 20 along the axial direction, and the filter section 32 is located at the other end of the cooling section 33. The support section 31 connects and supports the medium section 20 and the cooling section 33 at both ends. The cooling section 33 is used to reduce the temperature of the aerosol so that the temperature of the aerosol flowing out of the filter section 32 is suitable, avoiding the problem of the aerosol "scalding" the mouth.

[0178] Thus, during use, the heat from the heated medium section 20 is conducted to the fragrance-carrying section 10, promoting the release of the fragrance substances it carries and premixing them with the outside cold air during inhalation. The mixture then enters the medium section 20 and mixes with the aerosol generated by the medium section 20. Furthermore, specific compounds can be added to the fragrance-carrying section 10, allowing the generated compounds to react with the medium section 20 to produce a fragrance-enhancing effect, making the aerosol fragrance components more pleasant during inhalation. Moreover, the fragrance-carrying section 10 in this embodiment also functions as a pre-plug section 34. On one hand, during use, the fragrance-carrying section 10 effectively reduces the probability of the medium section 20 falling out of the outer packaging layer 40. On the other hand, after inhalation, the negative pressure generated during inhalation can cause aerosol backflow / recirculation in the receiving chamber. The pleated filling section has a good adsorption effect, adsorbing the aerosol during backflow / recirculation, which helps improve the problem of the receiving chamber being contaminated by aerosols and difficult to clean, and also helps improve the problem of cross-contamination of flavors when inhaling different flavored aerosol-generated products 100.

[0179] Of course, the positions of the support section 31 and the cooling section 33 can also be interchanged, that is, the cooling section 33 is connected to the end of the medium section 20 away from the fragrance section 10, and the two ends of the support section 31 are connected to the other end of the cooling section 33 and the filter section 32 respectively.

[0180] The structure of the support section 31 is not limited. For example, it can be a hollow paper tube structure or a hollow aluminum foil tube structure. Hollow paper tube structures and hollow aluminum foil tube structures have good heat resistance, are not easily deformed when heated, and can still maintain their shape after receiving heat conduction, which can increase the structural stability of the aerosol-generated product 100.

[0181] Of course, it can also be a hollow cellulose acetate structure, a hollow aluminum foil paper tube structure, a hollow silicone structure, etc.

[0182] The cooling section 33 can be, for example, a hollow paper tube, a cellulose acetate tube, or an aluminum foil tube. In one embodiment, the cooling section 33 has a porous structure. When the airflow carrying aerosols passes through the cooling section 33, a Venturi effect is formed (the Venturi effect refers to the phenomenon that the fluid velocity increases when the fluid passes through a narrowed flow cross-section, and the flow velocity is inversely proportional to the flow cross-section). The aerosols can pass through the cooling section 33 more quickly, thereby allowing for faster extraction of the aerosols. The cooling section 33 has a large specific surface area, which enables rapid cooling of the aerosols.

[0183] Of course, the cooling section 33 can also be one of hollow cellulose acetate or corrugated paper tubes.

[0184] The outer packaging layer 40 can wrap around the outer periphery of the basic structural section 30.

[0185] It should be noted that when the outer packaging layer 40 covers the entire circumferential outer surface of the filter section 32, the user can directly put the outer packaging layer 40 in their mouth to use the aerosol. When the outer packaging layer 40 covers part of the circumferential outer surface of the filter section 32, the user can directly put the part of the filter section 32 exposed outside the outer packaging layer 40 in their mouth to inhale the aerosol. Of course, the user can also attach a mouthpiece to the filter section 32 and inhale the aerosol through the mouthpiece.

[0186] It should be noted that the outer packaging layer 40 can be a single layer, that is, a single outer packaging layer 40 simultaneously wraps the medium segment 20, the fragrance segment 10, and the basic structure segment 30.

[0187] Of course, the outer packaging layer 40 can also be multi-layered. Any one of the medium segment 20, the fragrance-carrying segment 10, and the basic structure segment 30 can be wrapped by at least one outer packaging layer 40 to obtain a multi-segment structure; or, at least two of the medium segment 20, the fragrance-carrying segment 10, and the basic structure segment 30 can be wrapped by at least one outer packaging layer 40 to obtain a multi-segment structure, and the multi-segment structure can be wrapped by one or more outer packaging layers 40 to obtain the aerosol-generated product 100.

[0188] Specifically, such as Figure 3 As shown, the aerosol generating article 100 includes a front plug section 34, and the basic structure section 30 includes a cooling section 33 and a filter section 32. The front plug section 34 is disposed at the distal lip end 100a of the aerosol generating article 100. The cooling section 33 is disposed at one end of the medium section 20 axially away from the front plug section 34, the fragrance-carrying section 10 is disposed at one end of the cooling section 33 axially close to the medium section 20, and the filter section 32 is disposed at the other end of the cooling section 33. The fragrance-carrying section 10 can connect and support the cooling section 33 and the medium section 20 at both ends. That is to say, in this embodiment, the fragrance-carrying section 10, in addition to having a fragrance-carrying function, also has a supporting function. The cooling section 33 is used to reduce the temperature of the aerosol so that the temperature of the aerosol flowing out of the filter section 32 is suitable, avoiding the problem of the aerosol being "scalding hot".

[0189] Specifically, such as Figure 4 As shown, the aerosol generating article 100 includes a front plug section 34, and the basic structure section 30 includes a support section 31 and a filter section 32. The front plug section 34 is disposed at the distal lip end 100a of the aerosol generating article 100. The fragrance-carrying section 10 is disposed at one end of the medium section 20 axially away from the front plug section 34, the support section 31 is disposed at one end of the fragrance-carrying section 10 axially close to the medium section 20, and the filter section 32 is disposed at the other end of the fragrance-carrying section 10. The support section 31 can connect and support the fragrance-carrying section 10 and the medium section 20 at both ends. That is to say, in this embodiment, the fragrance-carrying section 10, in addition to having a fragrance-carrying function, also has a cooling function to reduce the temperature of the aerosol, so that the temperature of the aerosol flowing out of the fragrance-carrying section 10 is suitable and avoids the problem of the aerosol "scalding the mouth".

[0190] Please see Figure 15 Thirdly, embodiments of this application provide a method for manufacturing a fragrance-carrying segment 10. It should be noted that this manufacturing method can be applied to the manufacture of the fragrance-carrying segment 10 in any embodiment of this application.

[0191] Manufacturing methods include:

[0192] S100: Fragrance substances are loaded onto the filler.

[0193] S200: Embossing the filler loaded with fragrance substances to obtain a pleated filling part.

[0194] S300: The filling part and the wrapping layer are brought together to form a fragrance-carrying segment.

[0195] It should be noted that the manufacturing method of the fragrance-carrying segment 10 in this embodiment is applicable to... Figures 12 to 14 Production line of any embodiment.

[0196] Embossing is a processing technique that uses embossing to create specific patterns and textures on the surface of a material. Under certain pressure and temperature, embossing can deform the material, creating equidistant creases / cracks, and inducing stress / elasticity in the paper during the crease process. This stress and elasticity, generated during the later forming process, allow the filler 12 to be evenly distributed within the wrapping layer 11.

[0197] Please see Figures 12 to 14 The production line includes an embossing device 3 and a gathering device 4.

[0198] After the base layer paper material 1 is processed, it becomes the filler 12. After passing through the embossing device 3, the filler 12 produces creases and becomes a pleated filling part.

[0199] The filling part and the wrapping paper 2 enter the gathering device 4, thereby gathering and forming the fragrance-carrying section 10.

[0200] Here, the fragrance substance may be loaded onto the base paper 1 and then the base paper 1 may be processed to form the filler 12; or the base paper 1 may be processed to form the filler 12 first and then the fragrance substance may be loaded onto the filler 12.

[0201] In one embodiment, the filling portion and the wrapping layer are brought together to form a fragrance-carrying segment, specifically including:

[0202] The filling portion and the wrapping layer 11 are brought together and shaped into the desired shape, such as a cylindrical structure or a non-cylindrical structure, to obtain a filling portion with a wrinkled shape.

[0203] It should be noted that the manufacturing method of the fragrance-carrying segment 10 in this embodiment is applicable to... Figure 13 or Figure 14 The production line shown.

[0204] In other words, in this embodiment, the filler 12 is gathered into a pleated filling part, and the wrapping layer 11 then covers the outer periphery of the filling part to achieve shaping. Thus, the fragrance-carrying segment 10 has lower requirements for the structural strength of the wrapping layer 11, and the range of materials for the wrapping layer 11 is wider.

[0205] The material of filler 12 is not limited. For example, it can be various types of paper.

[0206] In related technologies, the filler 12 is made of polymer materials such as PLA (Polylactic acid), PET (Polyethylene glycol terephthalate), and CA (Cellulose acetate). During use, the fragrance-carrying section 10 is prone to melting, condensation, and collapse when in contact with the heating element. This causes blockage of the channel 10a inside the fragrance-carrying section 10, hindering the airflow from flowing through the channel 10a to the medium section 20 for aerosol extraction. As a result, the suction resistance of the aerosol-generated product 100 increases significantly during the suction process, and chemical impurities are generated, affecting the user experience.

[0207] The paper-based filler 12 can operate normally at temperatures below 420°C, while the heating temperature of a typical aerosol generating device is 200–320°C. Therefore, the filler 12 is less prone to melting or condensation when in contact with the heating element, reducing the likelihood of blockage in the channels 10a inside the fragrance-carrying section 10. This avoids a significant increase in suction resistance during the suction process. Furthermore, the paper material does not produce a chemical odor when heated. In addition, the paper-based filler 12 has good adsorption properties, and folding it into a pleated shape further enhances its adsorption effect, thereby improving its adsorption performance for aerosols during backflow / reverse flow.

[0208] In one embodiment, the filler 12 is made of fiber paper.

[0209] The filler 12, made of fiber paper, gives the fragrance-carrying section 10 better filling strength, which can improve the production qualification rate of the product during subsequent processing. At the same time, it can also improve the connection strength between the fragrance-carrying section 10 and the medium section 20, and improve the problems of bending and breakage of the aerosol-generated product 100 caused by insufficient connection strength during use.

[0210] In addition, during the heating process, the fibrous odor produced by the fiber paper can be confined inside the fiber paper, thereby improving the user experience.

[0211] In one embodiment, the basis weight of the fiber paper is in the range of 20 g / m². 2 -140g / m 2 For example, it could be 20g / m³. 2 30g / m 2 40g / m 2 50g / m 2 60g / m 2 70g / m 280g / m 2 90g / m 2 100g / m 2 110g / m 2 120g / m 2 130g / m 2 140g / m 2 etc.

[0212] It should be noted that when the basis weight of the fiber paper is low, its processing performance is low, resulting in a relatively low yield of the fragrance segment 10. When the basis weight is high, the paper impurities generated by the filler 12 are heavier during subsequent use, affecting the user's experience.

[0213] In this embodiment, the basis weight of the fiber paper is controlled at 20 g / m². 2 -140g / m 2 Within this range, it is possible to minimize the generation of paper impurities while ensuring the processing performance of the fiber paper. In other words, it is possible to ensure the yield of the fragrance-carrying segment 10 while also taking into account the user experience.

[0214] In one embodiment, the filling portion and the wrapping layer 11 are brought together to form a fragrance-carrying segment 10, specifically including:

[0215] It should be noted that the manufacturing method of the fragrance-carrying segment 10 in this embodiment is applicable to... Figures 10 to 12 Production line of any embodiment.

[0216] In other words, in this embodiment, the filling part is wrapped by the wrapping layer 11, and the filling part is constrained by the shape of the wrapping layer 11, thereby gathering under the constraint of the wrapping layer 11.

[0217] In this embodiment, a coating layer 11 with higher hardness can be selected. In this way, the probability of damage to the coating layer 11 during the aggregation and molding process is reduced.

[0218] By using the wrapping layer 11 to wrap the filling part, the shaping requirements of the filling part are reduced, and the filling part only needs to be wrapped by the wrapping layer 11 and deformed.

[0219] The fragrance-carrying segment 10 in this embodiment comprises a wrapping layer 11 and a filling portion. The filling portion is formed by embossing a layered filler 12 and has a pleated shape. The filling portion is disposed within the wrapping layer 11 to construct a channel 10a extending from one end of the fragrance-carrying segment 10 to the other end within the wrapping layer 11. Here, by setting the filling portion as a pleated structure formed by embossing a layered filler 12, the pleated filling portion has a better adsorption effect, which is beneficial to improving the fragrance-carrying capacity of the fragrance-carrying segment 10, thereby improving the fragrance richness and fragrance consistency in the aerosol, and thus improving the user's user experience. In addition, the filling part is disposed in the encapsulation layer 11 to form a channel 10a extending from one end of the fragrance segment 10 to the other end within the encapsulation layer 11. When the fragrance substance loaded on the filling member 12 is heated, it is released into the channel 10a and mixed with the air and / or aerosol in the channel 10a before being inhaled by the user. This can effectively reduce the suction resistance generated by the fragrance segment 10 on the inhaled aerosol and improve the user's user experience.

[0220] In one embodiment, a fragrance substance is loaded onto the filler 12, including:

[0221] The liquid fragrance substance is sprayed onto the filler 12.

[0222] In this embodiment, the fragrance substance is in liquid form. The liquid fragrance substance is evenly sprayed onto the filler 12 using an atomizing device, thereby loading the fragrance substance onto the filler 12. This method is simple and convenient, and it helps to improve the uniformity of the fragrance substance loaded on the filler 12.

[0223] In other embodiments, a fragrance substance is loaded onto the filler 12, including:

[0224] Spray the colloid onto filler 12;

[0225] A solid fragrance substance is disposed on the filler 12, and at least part of the fragrance substance is attached to the surface of the filler 12 by means of a colloid.

[0226] Here, the colloid can be evenly sprayed onto the filler 12 using an atomizing device.

[0227] Solid fragrance components (such as powdered fragrance, gel particles, fragrance carrier particles, etc.) are evenly distributed on the filler 12 sprayed with colloid using gravity feeding or other methods.

[0228] In this embodiment, by spraying an adhesive onto the filler 12, the solid fragrance substance can adhere to the surface of the filler 12 through the adhesive. In other words, spraying an adhesive onto the filler 12 helps to increase the loading capacity of the fragrance substance.

[0229] It should be noted that the specific type of colloid is not limited here.

[0230] In one embodiment, the colloid includes at least one of latex, aqueous latex, polysaccharide, and carboxymethyl cellulose.

[0231] In one embodiment, after covering the outer periphery of the filling portion with a wrapping layer 11 to obtain the fragrance-carrying segment 10, the manufacturing method includes:

[0232] The aromatic segment 10 is cut into pieces.

[0233] It should be noted that the manufacturing method of the fragrance-carrying segment 10 in this embodiment is applicable to... Figures 12 to 14 Production line of any embodiment.

[0234] Please see Figures 12 to 14 The fragrance-carrying segment 10 can be cut into a set length by the slitting device 5. In this way, the fragrance-carrying segment 10 of the set length can meet the usage requirements of the aerosol-generated product 100.

[0235] It is understandable that there is no limit to the specific value of the set length, and the set length can be set according to the usage requirements of the aerosol generated product 100.

[0236] The slitting device 5 generally includes a slitting tool, which slits the fragrance-carrying segment 10 through physical contact or non-physical contact.

[0237] Physical contact refers to cutting the fragrance segment 10 by direct contact between a slitting tool and the fragrance segment 10. For example, the slitting tool can be a rotary cutter, a cutting disc, a cutting line, a roller cutter, or an extruder.

[0238] Non-physical contact means that the cutting tool does not need to directly contact the fragrance-carrying segment 10 to cut it. For example, the cutting tool releases laser, plasma, air blade, or water jet to cut the fragrance-carrying segment 10.

[0239] In one embodiment, the manufacturing method includes slitting the filler 12 before loading the fragrance substance onto the filler 12.

[0240] Before loading the fragrance substance onto the filler 12, the filler 12 is slit, that is, the filler 12 is slit to the target width for use in the later processing.

[0241] In one specific embodiment, the method for manufacturing the fragrance-carrying segment 10 includes:

[0242] S01: Slitting: Provide a base layer 121, which can be made of materials such as fiber paper, non-woven fabric, PLA, etc., and slit the base layer 121. The purpose of this step is to slit the base layer 121 to the target width to obtain the filler 12 for use in the later processing.

[0243] S02: Spraying fragrance: The desired liquid fragrance components, such as fragrances, are evenly sprayed onto the filler 12 obtained in step S01 using an atomizing device to obtain a filler 12 loaded with fragrance substances.

[0244] S03: Embossing: Embossing is performed on the fragrance-loaded filler 12 obtained in step S02. Embossing is a processing technique that uses embossing dies to form specific patterns and textures on the surface of a material. Under certain pressure and temperature, embossing can deform the material, creating equidistant creases / cracks, and causing stress / elasticity in the paper during the crease process. This stress and elasticity allow the filler 12 to be evenly distributed within the wrapping layer 11 after the paper is formed in the later stages.

[0245] S04: Gathering and shaping: The embossed filler 12 obtained in step S03 is gathered, gathered, surrounded and piled up, and the filler 12 is wrapped and shaped. After the outer wrapping layer 11 is applied, the fragrance-carrying segment 10 is obtained.

[0246] S05: Slitting: Slit the fragrance-carrying segments to the target length for use in later production processes.

[0247] In another specific embodiment, the method for manufacturing the fragrance-carrying segment 10 includes:

[0248] S11: Slitting: Provide a base layer 121, which can be one or more materials such as fiber paper, non-woven fabric, PLA, etc., and slit the base layer 121. The purpose of this step is to slit the base layer 121 to the target width to obtain the filler 12 for use in the later processing.

[0249] S12: Spraying the colloid: The required colloid is evenly sprayed onto the filler 12 obtained in step S11 using an atomizing device. The purpose is to increase the loading capacity of the filler 12 for solid fragrance substances. The colloids used in the above adhesive are latex, water-based latex, polysaccharides, CMC (carboxymethyl cellulose), etc.

[0250] S13: Addition of solid fragrance substances: Solid fragrance substances (such as powdered fragrance, gel particles, fragrance-carrying particles, etc.) are evenly distributed on the filler 12 obtained in step S12 by means of gravity feeding, etc., to obtain the filler 12 loaded with fragrance substances.

[0251] S14: Embossing: Embossing is performed on the filler 12 loaded with fragrance obtained in step S13. Embossing is a processing technique that uses embossing dies to form specific patterns and textures on the surface of a material. Under certain pressure and temperature, embossing can deform the material, producing equidistant creases / cracks, and causing stress / elasticity in the paper during the crease process. This stress and elasticity allow the filler 12 to be evenly distributed within the wrapping layer 11 after the paper is formed in the later stages.

[0252] S15: Gathering and shaping: Gather the embossed filler 12 obtained in step S14, gather and surround it, and wrap and shape the filler 12. After covering it with an outer wrapping layer 11, the fragrance-carrying segment 10 is obtained.

[0253] S16: Slitting: Slit the fragrance-carrying segments to the target length for use in later production processes.

[0254] The following three specific embodiments will be used to illustrate the following:

[0255] First Embodiment

[0256] The desired fragrance and flavoring substances are evenly sprayed through an atomizing nozzle onto a 60g / m² area with a width of 5d. 2 On the surface of the base paper material 1 made of broad-leaf fiber, the fragrance and flavoring are sprayed at a mass of 45% of the weight of the base paper material 1 per unit area. After embossing and gathering, a 0.2mm wrapping layer 11 is wrapped on the outer layer to obtain the fragrance-carrying segment 10. Then the fragrance-carrying segment 10 is cut into 7mm pieces.

[0257] Please see Figure 2 In this embodiment, the fragrance-carrying section 10 is disposed at the distal lip end 100a of the aerosol generating article 100, and the aerosol generating article 100 is obtained by setting the medium section 20 and the basic structure section 30 (including at least one of the support section 31, the filter section 32 and the cooling section 33) with the same outer diameter according to the length ratio of 6:12:35.

After embossing and gathering, a 0.25mm wrapping layer 11 is wrapped around the outer layer to obtain the fragrance-loaded segment 10. The fragrance-loaded segment 10 is then cut into 12mm pieces.

[0260] Please see Figure 3In this embodiment, the aerosol generating article 100 includes a front plug section 34, and the basic structure section 30 includes a cooling section 33 and a filtering section 32.

The fragrance-carrying section 10 can connect and support the cooling section 33 and the medium section 20 at both ends. That is to say, in this embodiment, the fragrance-carrying section 10, in addition to having a fragrance-carrying function, also has a supporting function. The cooling section 33 is used to reduce the temperature of the aerosol so that the temperature of the aerosol flowing out of the filtering section 32 is suitable, avoiding the problem of the aerosol being "scalding hot".

[0261] By setting the lengths of the front plug section 34, medium section 20, fragrance-carrying section 10, cooling section 33, and filter section 32 of the same outer diameter according to the ratio of length 5:12:12:15:7, aerosol generating product 100 can be obtained.

[0262] Third Embodiment

[0263] At 70g / m² with a 13d width 2 A colloid is evenly sprayed onto the surface of a base paper material 1 made of broad-leaf fiber using an atomizing nozzle. Then, fragrance gel particles, accounting for 65% of the weight of the base paper material 1 per unit area, are evenly attached to the surface of the base paper material 1 by gravity feeding to obtain a high fragrance-loaded filler 12. After embossing and gathering, a 0.22mm wrapping layer 11 is wrapped around the outer layer to obtain the fragrance-loaded segment 10. The fragrance-loaded segment 10 is then cut into 8mm pieces.

[0264] Please see Figure 4 In this embodiment, the aerosol generating article 100 includes a front plug section 34, and the basic structure section 30 includes a support section 31 and a filter section 32. The front plug section 34 is disposed at the distal lip end 100a of the aerosol generating article 100.

The support section 31 can connect and support the fragrance-carrying section 10 and the medium section 20 at both ends. That is to say, in this embodiment, the fragrance-carrying section 10, in addition to having a fragrance-carrying function, also has a cooling function to reduce the temperature of the aerosol, so that the temperature of the aerosol flowing out of the fragrance-carrying section 10 is suitable and avoids the problem of the aerosol "scalding the mouth".

[0265] By setting the lengths of the front plug section 34, medium section 20, support section 31, fragrance-carrying section 10, and filter section 32 of the same outer diameter in a ratio of 4:13:12:8:12, aerosol-generating product 100 can be obtained.
