[0029] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0030] In the embodiments of this application, "first direction" refers to the direction shown in the accompanying drawings. It should be understood that these directional terms are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please see Figure 7 First, we will introduce the basic structure of the matrix strip 2, the aerosol generating product, and the aerosol generating system provided in the embodiments of this application.

[0032] Please see Figures 1 to 7 This application provides an aerosol generating article, including a matrix strip 2 and a nozzle 1 as described in any embodiment of this application.

[0033] The aerosol generation system provided in this application includes the aerosol generation article in any embodiment of this application. The aerosol generation system also includes an aerosol generation device with a heating element, which is used to heat the matrix strip 2.

[0034] The heating element is used to heat the matrix strip 2 to generate an aerosol.

[0035] The heating element can convert electrical energy into heat energy, which acts on the matrix strip 2. After being heated, the matrix strip 2 can generate aerosol for user use.

[0036] For example, the aerosol generating device further includes a housing and a power supply component disposed within the housing. The housing has a receiving chamber, and the power output section of the power supply component is disposed within the receiving chamber or around the side wall of the receiving chamber. When the matrix strip 2 or the aerosol generating article is inserted into the receiving chamber at the part corresponding to the matrix strip 2, the power output section transmits electrical energy to the heating element in a contact or non-contact manner. The heating element receives the electrical energy and generates heat, thereby heating the matrix strip 2 and generating aerosol.

[0037] The heating element can generate heat through methods including, but not limited to, resistance heating, electromagnetic heating, infrared heating, ceramic heating, microwave heating, or laser heating. The heat generated by the heating element can be transferred to the substrate strip 2 through heat convection, heat conduction, or heat radiation. For example, resistance and electromagnetic heating primarily transfer heat to the substrate strip 2 through heat conduction or heat convection. Infrared heating, microwave heating, or laser heating primarily transfer heat to the substrate strip 2 through heat radiation. The heating element can heat the substrate strip 2 through one or more of these three methods: heat conduction, heat convection, and heat radiation.

[0038] In this embodiment, the direction in which the aerosol-generated article is inserted into the receiving chamber and the direction in which the aerosol-generated article is taken out of the receiving chamber are both parallel to the first direction.

[0039] For ease of description, the two ends of the first direction are defined as the proximal lip end and the distal lip end. The proximal lip end refers to the end of the aerosol-generating product that is closer to the user when using it, while the distal lip end refers to the end of the aerosol-generating product that is farther away from the user. During use, the aerosol generated by the matrix strip 2 flows through the nozzle 1 under the suction negative pressure and is supplied to the user. In other words, the nozzle 1 is downstream of the matrix strip 2 along the first direction, i.e., the proximal lip end.

[0040] In this embodiment, the matrix strip 2 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.

[0041] It should be noted that, unless otherwise stated, in the embodiments of this application, the cross-section is a plane perpendicular to the first direction.

[0042] In some embodiments, the matrix strip 2 is a one-piece structure. For example, the matrix strip 2 can be formed into a one-piece structure by processes such as extrusion, injection molding, and compression molding, and is preferably manufactured by extrusion molding.

[0043] Extrusion molding is a processing method in which materials are fed into an extruder, and the materials are heated and plasticized by the action between the extruder barrel and the screw, and pushed forward by the screw, and continuously passed through the die head to form products or semi-finished products with various cross-sections.

[0044] The extruded matrix strip 2 is strip-shaped. Thus, the matrix strip 2 remains a single medium after being heated and drawn in or after heating stops, making it less prone to disintegration and falling off. This solves the problems of thin sheet, dispersed granular, and filamentous aerosol generating matrices in the prior art, which are prone to issues such as thin sheet detachment, filamentous component shedding, and difficulty in cleaning.

[0045] In some embodiments, the matrix strip 2 has an air passage 2a that can pass through at least one end face of the matrix strip 2 along a first direction.

[0046] The number of airway orifices 2a is unlimited; there can be one or more airway orifices 2a.

[0047] In some embodiments, the matrix strip 2 has micropores. The micropores not only increase the surface area of ​​the matrix strip 2, facilitating heat transfer and improving heating efficiency, but also allow aerosols generated by the medium far from the airway pores 2a to be gradually released into the airway pores 2a through the micropores, thereby improving the extraction efficiency of the active ingredients of the matrix strip 2.

[0048] Micropores refer to pores with a hydraulic diameter of no more than 100 μm in the flow cross-section. The flow cross-section refers to the cross-section perpendicular to the streamline cluster, i.e., the airflow.

[0049] In some embodiments, there are multiple micropores, and at least some of the micropores are connected to form a microchannel. When the matrix strip 2 is heated, it releases aerosols, which are collected into the airway pores 2a through the microchannels. Aerosols released by the medium exposed to the airway pores 2a (i.e., the material located on the pore surface of the airway pores 2a) can be directly released into the airway pores 2a. Aerosols between adjacent airway pores 2a can also flow between each other through the microchannels and be transported downstream, i.e., to the end where the nozzle 1 is located, under the action of suction negative pressure.

[0050] In some embodiments, the matrix strip 2 is a particle aggregate, with micropores between the particles. For example, the cross-sectional area and length of the micropores are naturally formed by the material components, and the expansion of the material components can form the micropores. Aerosols can flow through the microchannels.

[0051] It should be noted that the micropores described in this application are different from the air passage holes 2a. Micropores are disordered, meaning they are difficult to generate in an orderly manner according to the design; that is, micropores are generated randomly. Air passage holes 2a are ordered, meaning they are mainly formed by design and are predictable. The air passage holes 2a described in this application are pores in a macroscopic sense, while micropores are pores in a microscopic sense. The cross-sectional area and length of the air passage holes 2a are much larger than those of micropores. Air passage holes 2a are mainly formed by design and processing. For example, air passage holes 2a are formed by mold processing. Therefore, the cross-sectional area and length of the air passage holes 2a can be changed according to design requirements. The size of micropores, on the other hand, is determined by the gap between particles. For example, if the material is granular, the matrix strip 2 formed by extruding the material has micropores. The cross-sectional area and length of the micropores are naturally formed through the extrusion process and the material composition. The expansion of the material after flowing out of the die can form micropores.

[0052] In some embodiments, the matrix strip 2 includes plant materials, auxiliary materials, smoke-generating materials, adhesive materials, and fragrance materials.

[0053] Plant-based ingredients are used to generate aerosols upon heating. Additive ingredients provide skeletal support for the plant-based ingredients. Smoke-generating ingredients produce a large amount of smoke upon heating. Binder ingredients bind the component ingredients together. Fragrance ingredients provide characteristic aromas. Thus, the plant-based and smoke-generating ingredients ensure sufficient aerosol generation, while the fragrance 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 matrix strip 2, facilitating aerosol extraction and flow. Binder ingredients ensure a stable mixture of plant-based powder and additives, preventing a loose structure.

[0054] In some embodiments, the plant-based raw materials are one or more combinations of tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants, which are powdered after being crushed. The plant-based raw materials are the core source of the aroma, and the endogenous substances in them can provide users with physiological satisfaction. Endogenous substances, such as alkaloids, enter the bloodstream and promote the pituitary gland to produce dopamine, thereby achieving physiological satisfaction.

[0055] In some embodiments, the auxiliary raw materials 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. The inorganic fillers can provide skeletal support for the plant materials, and their micropores can increase the porosity of matrix strip 2, thereby improving the aerosol release rate.

[0056] Lubricants include one or more of the following: candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase the flowability of plant-based powders, reduce friction between powder particles, resulting in a more uniform overall density of the powder. They can also reduce the pressure required during extrusion molding and decrease die wear.

[0057] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can, to some extent, slow down the loss of aroma compounds during storage, increase their stability, and improve the sensory quality of the product.

[0058] In some embodiments, the smoke-generating agent raw material 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, a mixture of diacetins, triethyl citrate, methyl 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 lauryl carbonate, triacetin, mesoerythritol, a mixture of diacetins, diethyl octanoate, triethyl citrate, methyl benzoate, phenylacetic acid, ethyl vanillate, triglyceride, and lauryl acetate).

[0059] In some embodiments, the binder material achieves close contact with the component material through interfacial wetting, generating intermolecular attraction and thus binding the component material, such as powder or liquid. The binder material can be one or more combinations of natural plant extracts or non-ionic modified viscous polysaccharides, including tamarind polysaccharide, guar gum, and modified cellulose (such as carboxymethyl cellulose). The binder is used to bond particles together, preventing them from easily falling apart. Furthermore, it improves the water resistance of matrix strip 2 and is harmless to the human body.

[0060] In some embodiments, the flavoring ingredient is used to provide characteristic aromas, such as hay, roasted sweetness, or solid or liquid substances of nicotine. The flavoring ingredient may include one or more combinations of tobacco, aromatic plant extracts, extracts, essential oils, and absolutes; the flavoring ingredient may include one or more monomeric aroma compounds, such as megastigmatrienone, neophytadiene, geraniol, nerol, etc.

[0061] Please see Figures 1 to 7The nozzle 1 provided in this application embodiment includes a wrapping structure 13 and at least one functional segment 11. The wrapping structure 13 wraps the functional segment 11. One end of the wrapping structure 13 has an interface 12 for connecting a matrix strip 2. The matrix strip 2 is used to generate aerosol when heated.

[0062] As an example, functional segment 11 can provide functions such as filtration, adsorption, aroma enhancement, dilution, cooling, or resistance adjustment.

[0063] Filtration function refers to the function of filtering out at least some of the particulate matter in aerosols.

[0064] Adsorption function refers to the ability to adsorb at least some impurities in aerosols. It can be understood that these impurities are substances that remove the active ingredients from the aerosol; the active ingredients are those that need to be provided to the user.

[0065] The aroma-enhancing function refers to the function of adding aroma-producing components to aerosols.

[0066] The dilution function refers to the function of reducing the concentration of active ingredients in aerosols.

[0067] Cooling function refers to the function of reducing the temperature of aerosols.

[0068] The suction resistance adjustment function refers to the ability to reduce or increase suction resistance, thereby controlling the flow rate and distribution of the aerosol and optimizing suction resistance and aerosol uniformity. During use, the matrix strip 2 is connected to the nozzle 1, and the user can use the nozzle 1 to draw in the aerosol generated by the matrix strip 2.

[0069] The active ingredients in aerosols include, but are not limited to, at least one of nicotine, flavoring substances, glycerin, propylene glycol, and plant polysaccharides.

[0070] Impurities include, but are not limited to, substances harmful to the human body, such as polycyclic aromatic hydrocarbons and nitrosamines.

[0071] The substrate strip 2 can be sold separately. Each substrate strip 2 can only be used once. The nozzle 1 can be used once or reused multiple times according to user needs.

[0072] The suction nozzle 1 provided in this application embodiment can be manufactured and sold separately. That is, the suction nozzle 1 and the matrix strip 2 can be manufactured separately. According to the user's needs, the separate matrix strip 2 can be assembled to the interface 12 of the suction nozzle 1. In this way, the user can freely combine the suction nozzle 1 and the matrix strip 2 according to the user's needs, which improves convenience.

[0073] The number of functional segments 11 can be one or more.

[0074] In the embodiments of this application, "multiple" includes two or more.

[0075] The number of functional segments 11 can be two, three, or four, etc.

[0076] In some embodiments, please refer to Figures 1 to 6 There are multiple functional segments 11, and the multiple functional segments 11 are arranged sequentially in the wrapping structure 13 along the first direction. The interface 12 is located at one end of the wrapping structure 13 along the first direction.

[0077] Interface 12 is located at one end of the wrapping structure 13 along the first direction. Specifically, the distal lip end of the nozzle 1 along the first direction has interface 12.

[0078] In this embodiment, the aerosol generated by the matrix strip 2 enters the nozzle 1 and flows sequentially through multiple functional sections 11 along the first direction. These multiple functional sections 11 can provide multi-stage filtration or other functions, allowing the nozzle 1 to offer a wider range of applications. At least two functional sections 11 have different functions; that is, the nozzle 1 can provide two or more functions. For example, the nozzle 1 can provide both filtration and aroma enhancement; it can provide both filtration and cooling; it can provide three functions: filtration, aroma enhancement, and cooling; it can provide three functions: filtration, adsorption, and cooling. The nozzle 1 can also provide four functions: filtration, adsorption, aroma enhancement, and cooling, and so on.

[0079] In some embodiments, please refer to Figures 1 to 6 Functional segment 11 is a single integrated structure. This results in good structural strength for functional segment 11, reducing the risk of partial structural detachment leading to overall structural collapse.

[0080] An integral structure refers to a structure manufactured through a single processing or integral molding process.

[0081] In related technologies, multiple functional segments are assembled onto a matrix strip. These functional segments are manufactured separately and then assembled one by one. This involves many assembly steps and requires additional fixing devices between the functional segments, resulting in high production costs and the functional segments being easily damaged during the assembly process.

[0082] In some embodiments, all functional segments 11 are a single integrated structure. In other words, all functional segments 11 are manufactured through a single processing or integral molding process, integrating them into a whole. This eliminates the need for secondary assembly, reduces assembly steps, and improves production efficiency. Multiple functional segments 11 can provide richer functionality, improve taste, and enhance the user experience.

[0083] In this embodiment, the functional segment 11 is generally cylindrical. The cylindrical shape can be a cylinder (i.e., the cross-sectional shape is circular), a prism (i.e., the cross-sectional shape is polygonal), an elliptical cylinder (i.e., the cross-sectional shape is elliptical), etc., and is not limited here.

[0084] The cross-sectional shape of each functional segment 11 can be the same or different. Taking the case where all functional segments 11 have the same cross-sectional shape as an example, this facilitates production.

[0085] In some embodiments, functional segment 11 is formed into an integral structure using injection molding, extrusion, or casting processes.

[0086] The use of injection molding to form a single structure for functional segment 11 means that the material of functional segment 11 is cooled and solidified in the injection mold. The injection molding process can be carried out under high pressure.

[0087] The use of extrusion process to form an integral structure for functional segment 11 refers to the interaction between the material of functional segment 11 and the extrusion screw of the extrusion device. All the material of functional segment 11 is heated and plasticized and pushed to the discharge port by the extrusion screw, and formed by the extrusion die.

[0088] The use of casting to form an integral structure for functional segment 11 means that the material of functional segment 11 is cooled and solidified in a casting mold. The casting process does not require pressure.

[0089] For example, all functional segments 11 are integrally formed using injection molding, extrusion, or casting processes.

[0090] All functional sections 11 are integrally molded using injection molding, meaning that the material of all functional sections 11 is cooled and solidified within the injection mold. The injection molding process can be performed under high pressure.

[0091] The integrated molding of all functional segments 11 by extrusion process refers to a processing method in which the materials of all functional segments 11 are heat-plasticized and pushed towards the discharge port by the extrusion screw through the interaction between the barrel and the extrusion screw of the extrusion device, and formed by the extrusion die.

[0092] The use of casting to form all functional sections 11 in one piece means that the material of all functional sections 11 is cooled and solidified in a casting mold. The casting process does not require pressure.

[0093] In this embodiment, all functional segments 11 are integrally formed using injection molding, extrusion, or casting processes. The manufacturing process is simple, and the bonding strength of the interfaces between the functional segments 11 can be improved. It also features a relatively short production cycle and a high yield rate.

[0094] In some embodiments, please refer to Figure 3 At least one functional segment 11 is an adsorption segment 111, which is used to adsorb volatile organic compounds in aerosols.

[0095] As an example, there can be one functional segment 11 as an adsorption segment 111, or there can be two or more functional segments 11 as adsorption segments 111.

[0096] Volatile organic compounds (VOCs) include, but are not limited to, formaldehyde and acrolein.

[0097] The adsorption section 111 fixes volatile organic compounds to the surface through physical adsorption (van der Waals forces) and / or chemical adsorption (surface functional group interaction).

[0098] In this embodiment, the adsorption section 111 is used to adsorb volatile organic compounds in the aerosol, which can reduce the risk of users inhaling volatile organic compounds and also improve the taste of the aerosol.

[0099] In some embodiments, the adsorption section 111 includes at least one of activated carbon, zeolite molecular sieve, metal-organic framework, activated alumina, and polymer adsorption resin.

[0100] The material of adsorption section 111 includes one of activated carbon, zeolite molecular sieve, metal-organic framework, activated alumina, and polymer adsorption resin. Alternatively, the material of adsorption section 111 includes multiple of activated carbon, zeolite molecular sieve, metal-organic framework, activated alumina, and polymer adsorption resin.

[0101] Activated carbon is formed by carbonization and activation of organic raw materials (coal, fruit shells or wood). Its surface has a large number of micropores (the diameter of the micropores can be 2nm-50nm). Activated carbon has a strong adsorption capacity for non-polar organic compounds (such as benzene series and toluene) and some polar molecules (such as aldehydes) by means of physical adsorption and chemical adsorption.

[0102] Zeolite molecular sieves are crystalline aluminosilicate materials that preferentially adsorb small molecules (such as water and carbon dioxide) and polar substances based on the molecular size sieving effect.

[0103] Metal-organic frameworks (MOFs) are porous crystalline materials formed by the self-assembly of metal ions and organic ligands. The pore size of MOFs can be precisely controlled between 1 nm and 10 nm.

[0104] Activated alumina is a porous γ-alumina particle with a surface rich in hydroxyl groups. Activated alumina is a polar adsorbent with strong thermal stability.

[0105] Polymer adsorption resins are highly cross-linked polystyrene or polyacrylate microspheres that can achieve selective adsorption through hydrophobic interactions (such as adsorption of benzene compounds) or ion exchange (such as heavy metal ions).

[0106] In some embodiments, please refer to Figure 3At least one functional segment 11 is a filter segment 112, which is used to filter PM2.5 particles in aerosols.

[0107] PM2.5 (Particulate Matter 2.5) refers to particulate matter in the air with an aerodynamic diameter of ≤2.5μm. It belongs to the category of fine particulate matter and is also known as respirable particulate matter or fine particulate matter.

[0108] In this embodiment, the filter section 112 is used to filter out PM2.5 particles, which not only improves safety but also improves the taste, making it more delicate and pure.

[0109] It should be noted that the unit "nm" stands for nanometer, and the unit "μm" stands for micrometer.

[0110] In some embodiments, the filter section 112 includes at least one of HEPA, ultrafine polypropylene fiber, activated carbon composite material, nanofiber, and organometallic framework.

[0111] The material of filter section 112 includes one of HEPA, ultrafine polypropylene fiber, activated carbon composite material, nanofiber, and organometallic framework. Alternatively, the material of filter section 112 includes multiple of HEPA, ultrafine polypropylene fiber, activated carbon composite material, nanofiber, and organometallic framework.

[0112] HEPA, or High Efficiency Particulate Air Filter, is composed of randomly arranged polypropylene fibers with a diameter of approximately 0.5μm-2μm. It intercepts particulate matter through a complex three-dimensional mesh structure.

[0113] Ultrafine polypropylene fibers are made from polypropylene using a melt-blown process, with fiber diameters ranging from 0.5μm to 5μm. After the polypropylene is melted at high temperatures, it is stretched into ultrafine fibers by a high-speed airflow to form a nonwoven fabric.

[0114] Activated carbon composite materials can be activated carbon particles combined with polymers (such as polyurethane), fibers (such as non-woven fabrics) or foams.

[0115] Nanofibers are fibers with a diameter of 1nm-100nm that can capture PM0.1 particles and have a highly efficient filtration effect.

[0116] In some embodiments, please refer to Figure 3 At least one functional segment 11 is a cooling segment 113, which is used to reduce the temperature of the aerosol.

[0117] As an example, it can be that one functional segment 11 is a cooling segment 113, or multiple functional segments 11 are cooling segments 113.

[0118] In this embodiment, the cooling section 113 reduces the temperature of the aerosol, which can, to some extent, avoid the risk of the aerosol being too hot and burning your mouth.

[0119] In some embodiments, the cooling section 113 includes at least one of ceramic, silicone, paper, polylactic acid, polybutylene adipate terephthalate, and cellulose acetate.

[0120] The cooling section 113 may be made of one of the following materials: ceramic, silica gel, paper, polylactic acid, polybutylene adipate terephthalate, and cellulose acetate. Alternatively, the cooling section 113 may be made of multiple materials including ceramic, silica gel, paper, polylactic acid, polybutylene adipate terephthalate, and cellulose acetate.

[0121] Silicone includes bio-silicone and medical-grade silicone, etc.

[0122] Paper can be made from plant fibers (wood pulp, bamboo pulp, cotton pulp) through pulping, papermaking and drying, and is friendly to human health and the environment.

[0123] Polylactic acid (PLA) can be produced by fermenting starchy plants such as corn and sugarcane to produce lactic acid, which is then polymerized into a high molecular weight. It is biodegradable and human-friendly.

[0124] Polybutylene adipate terephthalate (PBAT) is a copolymer of adipic acid, terephthalic acid, and butanediol, and is biodegradable.

[0125] Cellulose acetate (CA) is made from wood pulp or cotton pulp through an acetylation reaction (acetic anhydride treatment). It is biodegradable and human-friendly.

[0126] In this embodiment, ceramics, silicone, paper, polylactic acid, polybutylene adipate terephthalate, and cellulose acetate are all human-friendly, and ceramics and silicone have high temperature resistance properties.

[0127] In some embodiments, please refer to Figures 1 to 3The system comprises multiple functional sections 11, including an adsorption section 111 and a filtration section 112. The adsorption section 111, filtration section 112, and cooling section 113 are arranged sequentially along a first direction, with the adsorption section 111 located on the side of the filtration section 112 closest to the matrix strip 2. In other words, the adsorption section 111, filtration section 112, and cooling section 113 are arranged sequentially from the distal lip end to the proximal lip end. The adsorption section 111 and filtration section 112 can reduce PM2.5 particles and volatile organic compounds, achieving the purpose of harm reduction, while the cooling section 113 can lower the inhalation temperature of the aerosol, improving the inhalation experience.

[0128] In some embodiments, please refer to Figure 6 At least one functional segment 11 is a quality improvement segment 114, which is used to filter PM10 particles in aerosols.

[0129] As an example, it can be one functional segment 11 as the quality improvement segment 114, or it can be multiple functional segments 11 as the quality improvement segment 114.

[0130] PM10 (Particulate Matter 10) refers to particulate matter in the air with an aerodynamic diameter of no more than 10 micrometers, also known as inhalable particulate matter or dust.

[0131] In this embodiment, the filter section 112 is used to filter out PM10 particles, which can not only improve safety but also improve taste.

[0132] In some embodiments, the upgrading section 114 includes at least one of polypropylene fiber, polyester fiber, HEPA, porous ceramic and activated carbon.

[0133] The material of the upgrading section 114 includes one of polypropylene fiber, polyester fiber, HEPA, porous ceramic, and activated carbon. Alternatively, the material of the upgrading section 114 includes multiple of polypropylene fiber, polyester fiber, HEPA, porous ceramic, and activated carbon.

[0134] Polypropylene fiber (PP) is made from isotactic polypropylene, which is produced by the polymerization of propylene, through melt spinning. The fiber filament fineness is ≤2.2dtex.

[0135] Polyester fiber (PET) is made by polycondensation of organic dicarboxylic acids (such as terephthalic acid) and diols (such as ethylene glycol).

[0136] Porous ceramics are ceramics with micropores.

[0137] In this embodiment, the pore sizes of polypropylene fiber, polyester fiber, HEPA, porous ceramic and activated carbon are moderate, which can provide the function of filtering PM10 level particulate matter.

[0138] In some embodiments, please refer to Figure 6 At least one functional segment 11 is a flavoring segment 115, which is used to provide flavoring components.

[0139] For example, one functional segment 11 may be a flavor-enhancing segment 115, or multiple functional segments 11 may be flavor-enhancing segments 115.

[0140] As an example, a fragrance ingredient can be added to the fragrance-enhancing section 115, and the fragrance ingredient releases the fragrance-generating components into the aerosol.

[0141] In this embodiment, the aroma-enhancing component can provide fragrance, making the aerosol taste richer.

[0142] In some embodiments, the flavoring segment 115 includes at least one of polyethylene glycol, polycaprolactone, microcrystalline cellulose, plant powder, carboxymethyl cellulose, sodium alginate, cellulose acetate, and polylactic acid.

[0143] The flavoring segment 115 may be made of one of the following: polyethylene glycol, polycaprolactone, microcrystalline cellulose, plant powder, carboxymethyl cellulose, sodium alginate, cellulose acetate, and polylactic acid. Alternatively, the flavoring segment 115 may be made of multiple of the following: polyethylene glycol, polycaprolactone, microcrystalline cellulose, plant powder, carboxymethyl cellulose, sodium alginate, cellulose acetate, and polylactic acid.

[0144] Polyethylene glycol (PEG) is a polymer compound formed by the polymerization of ethylene glycol monomers through ether bonds (-O-CH2-CH2-O-). It is human-friendly and water-soluble.

[0145] Polycaprolactone (PCL) is an aliphatic polyester formed by the ring-opening polymerization of ε-caprolactone. It is biodegradable and human-friendly.

[0146] Microcrystalline cellulose is produced by mechanically pulverizing α-cellulose after acid hydrolysis, and it is human-friendly.

[0147] Plant powder is a natural powder made from plant tissues (such as roots, stems, and leaves) through drying and pulverization. Its components include cellulose, lignin, and polysaccharides, and it is friendly to the human body.

[0148] Carboxymethyl cellulose is a product of cellulose modified by carboxymethylation, and it is human-friendly.

[0149] Sodium alginate is a natural polysaccharide extracted from brown algae, composed of β-D-mannuronic acid (M) and α-L-guluronic acid (G) units.

[0150] In this embodiment, polyethylene glycol, polycaprolactone, microcrystalline cellulose, plant powder, carboxymethyl cellulose, sodium alginate, cellulose acetate, and polylactic acid are all human-friendly and most are biodegradable. The plant powder can be used to provide aroma components.

[0151] In some embodiments, please refer to Figure 6 At least one functional segment 11 is a mixing segment 116, which is used to mix aerosols and aroma-enhancing components from the aroma-enhancing segment 115.

[0152] In this embodiment, the mixing section 116 can provide a mixing space for aerosols and aroma components, extending the path of aerosols into the mouth, so that the aerosols and aroma components are mixed more evenly.

[0153] In some embodiments, the mixing segment 116 includes at least one of ceramic, silicone, paper, polylactic acid, polybutylene adipate, and cellulose acetate.

[0154] The material of the mixed segment 116 may include one of ceramics, silicone, paper, polylactic acid, polybutylene adipate, and cellulose acetate. Alternatively, the material of the mixed segment 116 may include multiple of ceramics, silicone, paper, polylactic acid, polybutylene adipate, and cellulose acetate.

[0155] In this embodiment, ceramics, silicone, paper, polylactic acid, polybutylene adipate terephthalate, and cellulose acetate are all human-friendly and produce virtually no harmful substances. Ceramics and silicone also have good temperature resistance and can be used to maintain the structural shape of the mixing section 116.

[0156] In some embodiments, please refer to Figures 4 to 6 The multiple functional sections 11 include an enhancing section 114, an aroma-enhancing section 115, and a mixing section 116 arranged sequentially along a first direction, with the enhancing section 114 located on the side of the aroma-enhancing section 115 closer to the matrix strip 2. In other words, the enhancing section 114, aroma-enhancing section 115, and mixing section 116 are arranged sequentially from the distal lip end to the proximal lip end. The enhancing section 114 can reduce PM10 particles, achieving filtration and harm reduction, while the aroma-enhancing section 115 and mixing section 116 can enrich the flavor of the aerosol and enhance the vaping experience.

[0157] In related technologies, the substrate strips and functional segments are fixed by means of bonding, which makes it difficult to flexibly adapt to substrate strips of different diameters. In addition, problems such as air leakage or installation difficulties are also likely to occur.

[0158] Interface 12 is detachably connected to substrate strip 2.

[0159] In some embodiments, please refer to Figures 1 to 7Interface 12 is used to insert substrate strip 2. Specifically, substrate strip 2 and interface 12 are interference-fitted.

[0160] The wall of interface 12 is elastic, and interface 12 can increase or decrease its cross-sectional area through elastic deformation. In this way, interface 12 can be used to adapt to substrate strips 2 of different diameters.

[0161] Here, the cross-sectional area of ​​interface 12 refers to the area of ​​the cross-sectional shape of interface 12 with a plane perpendicular to the first direction as the cross-section.

[0162] In some embodiments, the diameter of the substrate strip 2 is 5mm-8mm. Exemplarily, the diameter of the substrate strip 2 is 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, or 8mm, etc. Substrate strips 2 within this diameter range can be plugged into the interface 12.

[0163] In this embodiment, the connection between the nozzle 1 and the substrate strip 2 can be completed simply by inserting the substrate strip 2 into the interface 12, achieving "plug and play" without the need for additional fixing devices, making operation simple. The nozzle 1 and the substrate strip 2 are detachably connected, and the nozzle 1 can be reused. Of course, the nozzle 1 can also be a disposable structure, meaning it is not reused after use.

[0164] In some embodiments, please refer to Figures 1 to 7 The wrapping structure 13 wraps around the periphery of all functional segments 11, and a portion of the wrapping structure 13 protrudes at one end in a first direction to form an interface 12. Specifically, a portion of the wrapping structure 13 protrudes at the distal lip end to form an interface 12.

[0165] In this embodiment, the wrapping structure 13 wraps around the outer periphery of all functional segments 11, which not only protects the functional segments 11 and reduces the risk of other objects contacting the functions, but also strengthens the connection between the functional segments 11, reducing the risk of the functional segments 11 falling off, and enhances the aesthetics of the nozzle 1. A portion of the wrapping structure 13 protrudes at one end in the first direction to form an interface 12. That is, the interface 12 is formed by the wrapping structure 13, which constitutes the sidewall of the interface 12. The forming method of the interface 12 is simple.

[0166] In some embodiments, the wrapping structure 13 is a single piece. This reduces the assembly steps required for the wrapping structure 13.

[0167] In some embodiments, all functional segments 11 and the enclosure structure 13 can be integrally molded. This can further reduce assembly steps.

[0168] In some embodiments, the wrapping structure 13 and the functional segment 11 are separate structures. That is, the wrapping structure 13 and the functional segment 11 are manufactured separately and then assembled together. As an example, the wrapping structure 13 can be bonded to the outer peripheral surface of the functional segment 11.

[0169] In some embodiments, an elastic clip is provided within the interface 12 to elastically engage with the substrate strip 2. This elastic clip provides a more secure hold on the substrate strip 2, reducing the risk of it detaching.

[0170] The shape of the elastic buckle is not limited. For example, the sidewall of the wrapping structure 13 forming the interface 12 protrudes inward to form the elastic buckle.

[0171] In some embodiments, the elastic limit of the wrapping structure 13 is greater than 5 MPa.

[0172] For example, the elastic limit of the wrapping structure 13 can be 5.1 MPa, 6 MPa, 10 MPa or more than 10 MPa.

[0173] The elastic limit refers to the maximum stress a material can withstand without permanent deformation (i.e., without plastic deformation) when subjected to external forces.

[0174] In this embodiment, the elastic limit of the wrapping structure 13 is greater than 5 MPa. The wrapping structure 13 is easy to recover its original shape after being deformed by force, that is, it has good reversible deformation ability and strong resistance to permanent deformation. It not only makes it easy for users to assemble the matrix strip 2 to the interface 12, reducing the risk of the interface 12 being easily damaged by small assembly forces, but the nozzle 1 can also meet the needs of repeated use.

[0175] In some embodiments, the permanent deformation rate of the wrapping structure 13 is less than 20%.

[0176] For example, the permanent deformation rate of the wrapping structure 13 can be 19%, 10%, 5%, or less than 5%.

[0177] The permanent deformation rate is the percentage of the irreversible deformation remaining in a material after the external force has been completely unloaded, relative to its original size.

[0178] In this embodiment, the permanent deformation rate of the wrapping structure 13 is less than 20%. The wrapping structure 13 is easy to recover its original shape after being deformed by force, that is, it has good reversible deformation ability and strong resistance to permanent deformation. It not only makes it easy for users to assemble the matrix strip 2 to the interface 12, reducing the risk of the interface 12 being easily damaged by small assembly forces, but also allows the nozzle 1 to meet the needs of repeated use.

[0179] In some embodiments, the encapsulation structure 13 includes at least one of silicone, polyamide, polyimide, ceramic, polyphenylene sulfide, polybutylene terephthalate, polylactic acid, polyethylene, and polyethylene terephthalate.

[0180] The material of the encapsulation structure 13 includes one of silicone, polyamide, polyimide, ceramic, polyphenylene sulfide, polybutylene terephthalate, polylactic acid, polyethylene, and polyethylene terephthalate. Alternatively, the material of the encapsulation structure 13 includes multiple materials selected from silicone, polyamide, polyimide, ceramic, polyphenylene sulfide, polybutylene terephthalate, polylactic acid, polyethylene, and polyethylene terephthalate.

[0181] Polyamide (PA) is a polymer material whose main chain contains repeating amide groups (-NH-CO-). It has the characteristics of high strength, good wear resistance, and good heat resistance.

[0182] Polyimide (PI) is an aromatic polymer containing an imine ring (-CO-NR-CO-) and has good heat resistance.

[0183] Polyphenylene sulfide (PPS) is a high-performance plastic whose main chain contains benzene rings and thioether bonds. It has the characteristics of chemical corrosion resistance and high temperature resistance.

[0184] Polyethylene (PE) has good flexibility, chemical resistance, and strong puncture resistance.

[0185] In this embodiment, silicone, polyamide, polyimide, ceramic, polyphenylene sulfide, polybutylene terephthalate, polylactic acid, polyethylene, and polyethylene terephthalate all have a certain degree of flexibility and can be bent to wrap the functional segment 11.

[0186] In some embodiments, the length of interface 12 is 2mm to 9mm.

[0187] For example, the length of interface 12 is any one value among 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm and 9mm or a point value between any two points.

[0188] In this embodiment, when the length of the interface 12 is less than 2mm, the connection strength between the substrate strip 2 and the interface 12 is low, and the substrate strip 2 is easy to fall off; when the length of the interface 12 is greater than 9mm, the length of the interface 12 is too long, and the resistance during the insertion of the substrate strip 2 into the interface 12 is greater, making the operation more difficult. Therefore, the length of the interface 12 is 2mm to 9mm, which can balance the connection strength between the substrate strip 2 and the nozzle 1 as well as the ease of operation.

[0189] It should be noted that in the embodiments of this application, the unit "mm" refers to millimeters.

[0190] In some embodiments, the length of the suction nozzle 1 is 10 mm to 60 mm.

[0191] For example, the length of the nozzle 1 is any value or any two of 10mm, 12mm, 15mm, 18mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm and 60mm.

[0192] In this embodiment, when the length of the nozzle 1 is less than 10mm, the length of the functional segment 11 is too short, resulting in a shorter path for the aerosol within the nozzle 1. This can easily reduce the effectiveness of each functional segment 11, such as filtration and aroma enhancement. When the length of the nozzle 1 is greater than 10mm, the overall length after connecting the matrix strip 2 or the aerosol generating device is too long, affecting the user experience. A nozzle 1 with a length between 10mm and 60mm provides a suitable overall length after connecting the matrix strip 2 or the aerosol generating device, making it easy for the user to hold and use, while also accommodating the required length of the functional segments 11, achieving good filtration and aroma enhancement effects.

[0193] The following describes the suction nozzle 1 provided in the embodiments of this application in further detail with reference to specific examples: Specific Implementation Example 1

[0195] Please see Figures 1 to 3 The nozzle 1 has three functional sections 11, which are the adsorption section 111, the filtration section 112, and the cooling section 113 arranged sequentially from the distal lip end to the proximal lip end. The three functional sections 11 are an integral structure.

[0196] The nozzle 1 has a length of 33mm along the first direction, wherein the adsorption section 111 has a length of 6mm along the first direction, the filtration section 112 has a length of 12mm along the first direction, the cooling section 113 has a length of 12mm along the first direction, and the interface 12 has a length of 3mm along the first direction.

[0197] The adsorption section 111 includes activated carbon and zeolite, wherein the mass ratio of activated carbon to zeolite is 7:3.

[0198] Filtering section 112 uses MOFS.

[0199] The cooling section 113 uses zirconium oxide.

[0200] Encapsulation structure 13 is made of bio-silicone.

[0201] The forming process of nozzle 1: After the adsorption section 111, the filtration section 112 and the cooling section 113 are cast and formed, the outer periphery of the above three functional sections 11 is covered by bio-silicone casting to form a wrapping structure 13.

[0202] The adsorption section 111 has a cylindrical profile and a first hole with a regular hexagonal cross-section, which passes through the two end faces of the adsorption section 111 along a first direction. The first hole can increase the flow rate of the aerosol. After the aerosol enters the adsorption section 111, the change in cross-section causes the aerosol to collide at the first hole, and larger particles in the aerosol settle. The first hole can also provide a large airflow contact area while ensuring good adsorption resistance, so that the material of the adsorption section 111 can adsorb VOCs and carbon monoxide in the aerosol.

[0203] The filter section 112 has a cylindrical outline and a second hole with a four-pointed star cross-section. The second hole passes through the two end faces of the filter section 112 along the first direction. The total volume of the second hole accounts for 65% of the total volume of the filter section 112. MOFS material is used to adsorb PM2.5 in the aerosol generated by the front adsorption section 111, thereby increasing the flow rate of the aerosol in the second hole.

[0204] The cooling section 113 has a cylindrical shape and is made of zirconium oxide material. It has micropores and a porosity of 0.78. During the suction process of the nozzle 1, the aerosol flows from the distal lip end to the proximal lip end. The cooling section 113 can increase the flow distance and reduce the temperature of the aerosol through the micropores.

[0205] In this embodiment, both the adsorption section 111 and the filtration section 112 can provide filtration functions. The nozzle 1 contains multi-stage filtration, and the tar rejection rate can be ≥90%, and carbon monoxide is reduced by 70%. The nozzle 1 can achieve the purpose of harm reduction filtration. Moreover, the temperature of the aerosol is reduced by more than 5°C compared with the direct use of the matrix strip 2. Specific Implementation Example 2

[0207] Please see Figures 4 to 6 The mouthpiece 1 has three functional sections 11, which are the quality-enhancing section 114, the aroma-enhancing section 115, and the cooling section 113 arranged sequentially from the distal lip end to the proximal lip end. The three functional sections 11 are an integral structure.

[0208] The nozzle 1 has a length of 36mm along the first direction, wherein the quality-enhancing section 114 has a length of 10mm along the first direction, the aroma-enhancing section 115 has a length of 12mm along the first direction, the cooling section 113 has a length of 14mm along the first direction, and the interface 12 has a length of 3mm along the first direction.

[0209] The upgrading section 114 includes 30% HEPA and 70% porous ceramic.

[0210] Flavoring component 115 comprises 10% microcrystalline cellulose, 80% plant powder, and 10% flavoring.

[0211] The cooling section 113 uses PBAT.

[0212] The encapsulation structure 13 is made of PE.

[0213] The forming process of nozzle 1: The quality improvement section 114, the aroma enhancement section 115, the cooling section 113, and the encapsulation structure 13 are all formed by step-by-step co-extrusion molding. That is to say, the three functional sections 11 and the encapsulation structure 13 are integrated into one structure.

[0214] The upgrading section 114 has a cylindrical outline and a hollow channel with an outer spiral channel around its outer periphery. Both the hollow channel and the outer spiral channel pass through the two end faces of the upgrading section 114 along the first direction. The hollow channel can increase the airflow velocity, causing the tar components in the aerosol to form larger particles and settle, and can also adsorb PM10 particles in the aerosol, improving the texture and smoothness of the aerosol.

[0215] The aroma-enhancing section 115 has a cylindrical outline and features a third and a fourth hole. Both the third and fourth holes have circular cross-sectional shapes and pass through the two end faces of the aroma-enhancing section 115 along a first direction. The diameter of the fourth hole is larger than that of the third hole. Multiple third holes are arranged in a circular pattern, and multiple fourth holes form concentric circles surrounding the outer periphery of the circle formed by the third holes. This design increases the proportion of airflow in the outer ring while simultaneously slowing down the airflow velocity, increasing the residence time of the airflow within the fourth holes, and enhancing the contact area during the flow through the fourth holes, thereby improving the overall aroma loading effect.

[0216] The cooling section 113 has a cylindrical outline and a fifth hole with a circular cross-section. Multiple fifth holes are arranged in a two-dimensional matrix, and multiple spiral grooves are formed on the outer circumference of the cooling section 113. This improves the uniformity of the aerosol and the airflow contact area, reducing the aerosol temperature. Furthermore, the spiral grooves increase the airflow velocity, allowing the aerosol flowing in the spiral grooves to coat the aerosol in the fifth hole during suction, improving aerosol agglomeration and a smooth, warm feel.

[0217] In this embodiment, the nozzle 1 can improve the smoothness of the aerosol, reduce wet tar by about 20%, and improve the consistency of aerosol and aroma release by about 30%.
