[0060] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0061] In the description of this application, the "first direction" orientation or position relationship is based on the attached Figure 1 and Figure 2 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0062] The present application embodiment provides an aerosol generating product, please refer to Figures 1 to 6 The aerosol-generating article 1 comprises an aerosol-generating substrate 11 and a functional segment 12 .

[0063] The functional segment 12 is disposed at one end of the aerosol generating substrate 11 along the first direction, and the functional segment 12 at least includes a filtering segment 122 for filtering aerosol.

[0064] The functional segment 12 is arranged at one end of the aerosol generating matrix 11 along the first direction, that is, the aerosol generating matrix 11 and the functional segment 12 are respectively located at the two ends of the aerosol generating product 1, wherein the aerosol generating matrix 11 is the far lip end of the aerosol generating product 1, and the functional segment 12 is the near lip end of the aerosol generating product 1.

[0065] The proximal lip end refers to the end of the aerosol generating article 1 that is close to the user when the user is using the aerosol generating article 1 , and the distal lip end refers to the end of the aerosol generating article 1 that is away from the user when the user is using the aerosol generating article 1 .

[0066] The functional section 12 comprises at least a filter section 122 for filtering aerosols.

[0067] It should be noted that the filter section 122 is used to filter the aerosol. It is understandable that since the aerosol flows through the filter section 122, the filter section 122 also has the function of further cooling the aerosol.

[0068] The functional section 12 has one or more functions of filtering, adjusting suction resistance, cooling, supporting, enhancing fragrance, adsorbing, and mixing aerosol.

[0069] The functional section 12 may further include a cooling section 121 which can be used to cool the aerosol.

[0070] The cooling section 121 may be disposed between the aerosol generating substrate 11 and the filtering section 122 .

[0071] Of course, the functional segment 12 may also have the functions of supporting and / or filtering and / or adjusting the suction resistance.

[0072] The aerosol-generating article 1 relies on the aerosol-generating substrate 11 to generate aerosol, and the functional section 12 is not used to generate aerosol.

[0073] In some embodiments, see Figures 4 to 6 The aerosol generating product 1 further comprises a wrapping layer 13, which wraps around the outer peripheral side of the functional segment 12 and the aerosol generating substrate 11. The wrapping layer 13 provides installation space and protection for the aerosol generating substrate 11 and the functional segment 12, reduces the probability of damage to the aerosol generating substrate 11 and the functional segment 12, and increases the reliability of the aerosol generating product 1.

[0074] Among them, the wrapping layer 13 wrapped around the outer peripheral side of the aerosol generating matrix 11 and the functional segment 12 can be the wrapping layer 13 wrapped around the entire outer peripheral side of the aerosol generating matrix 11 and the functional segment 12, or the wrapping layer 13 wrapped around part of the outer peripheral side of the aerosol generating matrix 11 and the functional segment 12.

[0075] It is understandable that the material of the wrapping layer 13 has a certain structural strength to reduce the probability of deformation of the aerosol generating article 1 due to airflow pressure during use.

[0076] The specific material of the wrapping layer 13 is not limited, such as one or more combinations of fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, PBAT (Poly (butyleneadipate-co-terephthalate, poly (butylene adipate-co-terephthalate)) and the like.

[0077] It should be noted that, when the wrapping layer 13 wraps the entire outer circumference of the functional segment 12, the user can directly hold the wrapping layer 13 in the mouth to inhale the aerosol; when the wrapping layer 13 wraps part of the outer circumference of the functional segment 12, the user can directly hold the part of the functional segment 12 extending beyond the wrapping layer 13 in the mouth to inhale the aerosol. Of course, the user can also provide a nozzle outside the functional segment 12 to inhale the aerosol through the nozzle.

[0078] The wrapping layer 13 is not limited to one layer. For example, during the manufacturing process, each section such as the aerosol generating matrix 11, the cooling section 121 and the filtering section 122 can be first wrapped by a wrapping layer 13, and then wrapped as a whole outside the wrapping layer 13 of each section by another wrapping layer 13.

[0079] It should be noted that the aerosol generating product 1 of the embodiment of the present application can be used for inhalation by ignition or by heating without burning. In the embodiment of the present application, the aerosol generating product 1 is used for inhalation by heating without burning as an example.

[0080] The aerosol generating article 1 is used in conjunction with an aerosol generating device having a heating element. Specifically, the heating element heats and atomizes the aerosol generating substrate 11 to generate an aerosol for users to inhale or for use in medicine, beauty, etc.

[0081] There are many heating methods for the heating element. Exemplarily, the heating methods include central heating and circumferential heating. The central heating method refers to the heating element being inserted into the aerosol generating substrate 11 to bake and heat the aerosol generating substrate 11 from the inside to the outside. The circumferential heating method refers to the heating element being arranged at the periphery of the aerosol generating substrate 11 to bake and heat the aerosol generating substrate 11 from the outside to the inside. These heating methods may specifically be resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, and the like.

[0082] The present application embodiment provides an aerosol generating substrate 11, see Figures 1 to 6 The aerosol generating substrate 11 comprises at least two media segments 111 arranged in sequence along a first direction. At least some of the media segments 111 have different structures and / or materials. Each media segment 111 is an integrated structure formed by a co-extrusion process.

[0083] It should be noted that, in the present application, a plurality includes two and more than two.

[0084] The aerosol generating substrate 11 includes at least two medium segments 111 arranged in sequence along the first direction, which means that the number of the medium segments 111 is two or more.

[0085] The structure of the medium segment 111 includes the number of airway holes 11a of the medium segment 111, the shape of the airway holes 11a, the hydraulic diameter of the airway holes 11a, the cross-sectional area of ​​the airway holes 11a, the arrangement of the airway holes 11a, the shape of the medium segment 111, the cross-sectional area of ​​the medium segment 111, etc.

[0086] In some embodiments, see Figures 1 to 6 Each medium segment 111 has at least one air passage hole 11a inside. The air passage hole 11a penetrates at least one end of the medium segment 111 along the first direction.

[0087] The inside of the medium segment 111 has at least one airway hole 11 a . The inside of the medium segment 111 may have one airway hole 11 a , or the inside of the medium segment 111 may have multiple airway holes 11 a .

[0088] It should be noted that the “multiple” mentioned in the embodiments of the present application refers to a number of two or more.

[0089] In some embodiments, the airway holes 11a pass through the same end of the medium segment 111 along the first direction, and the other end is closed.

[0090] In other embodiments, a portion of the airway holes 11 a passes through one end of the medium segment 111 along the first direction, and another portion of the airway holes 11 a passes through the other end of the medium segment 111 along the first direction.

[0091] In some other embodiments, please refer to Figures 1 to 6 Each airway hole 11a passes through both ends of the medium segment 111 along the first direction, that is, the airway hole 11a extends along the first direction of the medium segment 111, and the airflow can flow from one end of the medium segment 111 through the airway hole 11a to the other end of the medium segment 111. Preferably, the airway hole 11a is parallel to the central axis of the medium segment 111.

[0092] Of course, the airway hole 11 a may also be configured to penetrate the side wall of the medium segment 111 .

[0093] In some embodiments, see Figures 2 to 3 The medium segment 111 has a through hole 11b inside, and the airway holes 11a are arranged around the through hole 11b. The through hole 11b penetrates at least one end of the medium segment 111 along the first direction.

[0094] The hole walls of the airway hole 11a and the through hole 11b constitute the inner surface of the medium segment 111. The airway hole 11a can increase the inner surface area of ​​the medium segment 111, facilitate heat transfer, and improve heating efficiency. In addition, the medium segment 111 generates aerosol after heating, and the aerosol is collected in the airway hole 11a and transported to the suction end under the action of the suction negative pressure. The airway hole 11a can reduce the suction resistance of the user and improve the user experience. It should be noted that the suction resistance is positively correlated with the flow resistance of the aerosol. The smaller the flow resistance of the aerosol in the medium segment 111, the smaller the suction resistance experienced by the user. The greater the flow resistance of the aerosol in the medium segment 111, the greater the suction resistance experienced by the user.

[0095] In the embodiment of the present application, the first direction does not specifically refer to the direction in which the outer contour of the medium segment 111 is the longest. Specifically, the direction in which the aerosol generating product 1 is inserted into the containing chamber and the direction in which the aerosol generating product 1 is taken out of the containing chamber are both parallel to the first direction. The length of the medium segment 111 along the first direction may be longer, shorter, or the same as the length in other directions.

[0096] For example, when the appearance of the medium segment 111 is cylindrical, the first direction is the axial direction of the medium segment 111. It should be noted that even when the axial length of the medium segment 111 is less than its diameter, the first direction of the medium segment 111 is still the axial direction. For another example, when the appearance of the medium segment 111 is a rectangular parallelepiped, the first direction is still the direction defined above, that is, the direction in which the aerosol generating product 1 is taken out of the containing chamber, and the first direction of the medium segment 111 can be any direction of the length, width, and height of the rectangular parallelepiped.

[0097] For example, in some embodiments, at least part of the structure and / or material of the medium segment 111 is different, which may be one of the number of airway holes 11a, the shape of the airway holes 11a, the hydraulic diameter of the airway holes 11a, the cross-sectional area of ​​the airway holes 11a, the arrangement of the airway holes 11a, the shape of the medium segment 111, the cross-sectional area of ​​the medium segment 111, and the material of the medium segment 111. For example, see Figure 1 , at least some of the media segments 111 are made of different materials, and the number of all the airway holes 11a, the shape of the airway holes 11a, the hydraulic diameter of the airway holes 11a, the cross-sectional area of ​​the airway holes 11a, the arrangement of the airway holes 11a, the shape of the media segments 111, and the cross-sectional area of ​​the media segments 111 are the same. Taking three media segments 111 as an example, two media segments 111 are made of different materials from another media segment 111, or the materials of the three media segments 111 are all different, and the number of the airway holes 11a, the shape of the airway holes 11a, the hydraulic diameter of the airway holes 11a, the cross-sectional area of ​​the airway holes 11a, the arrangement of the airway holes 11a, the shape of the media segments 111, and the cross-sectional area of ​​the media segments 111 of the three media segments 111 are the same.

[0098] In other embodiments, at least some of the media segments 111 have different structures and / or materials, which may be at least two of the number of airway holes 11a, the shape of the airway holes 11a, the hydraulic diameter of the airway holes 11a, the cross-sectional area of ​​the airway holes 11a, the arrangement of the airway holes 11a, the shape of the media segment 111, the cross-sectional area of ​​the media segment 111, and the material of the media segment 111. For example, at least some of the media segments 111 have different parameters, the number of airway holes 11a and the shape of the airway holes 11a, and the material of all the media segments 111 are the same.

[0099] The material of the dielectric segment 111 includes components and ratios of the components.

[0100] The shape of the airway hole 11a includes the cross-sectional shape of the airway hole 11a and the spatial shape of the airway hole 11a. The cross-sectional shape is a plane perpendicular to the length direction of the medium segment 111. The cross-sectional shape of the airway hole 11a refers to the shape of a single airway hole 11a cut in a cross section.

[0101] The hydraulic diameter refers to the ratio of four times the cross-sectional area of ​​the flow passage to the perimeter. The flow passage refers to the cross-section taken by the streamline cluster perpendicular to the fluid. For example, if the cross-sectional shape of the airway hole 11a is a regular quadrilateral, the hydraulic diameter is the ratio of four times the cross-sectional area of ​​the regular quadrilateral airway hole 11a to the perimeter of the regular quadrilateral deformation. For another example, if the cross-sectional shape of the airway hole 11a is a circle, the hydraulic diameter is the diameter of the circular airway hole 11a.

[0102] The arrangement of the airway holes 11 a refers to the distribution pattern of the airway holes 11 a on the medium segment 111 .

[0103] The embodiment of the present application provides an aerosol generating matrix 11, and the aerosol generating matrix 11 includes a plurality of medium segments 111 arranged in sequence along a first direction. The structure and / or material of at least some of the medium segments 111 are different. Each medium segment 111 is an integrated structure formed by a co-extrusion process. In other words, the aerosol generating matrix 11 is a multi-segment structure, that is, the aerosol generating matrix 11 includes a plurality of medium segments 111, and the medium segments 111 are arranged in sequence in the first direction, and the structure and / or material of at least some of the medium segments 111 are different. In this way, the structure and / or material of each medium segment 111 can be set as needed. By adjusting the structure of the medium segment 111, the flow velocity and / or flow rate of the airflow can be adjusted, thereby achieving the effect of adjusting the extraction rate of the aerosol. By adjusting the material of the medium segment 111, the richness of the aerosol can be improved, thereby improving the user experience.

[0104] In the related art, the smoking materials of smoking products are, for example, granular, shredded tobacco, thin sheets, etc., which are formed by integral filling, rolling or gathering. When shredded tobacco smoking products are matched with a central heat source, the central material of the smoking products tends to move upward, resulting in "shred blocking". Granular smoking products are prone to poor uniformity of filling particle shape during production and processing, and the seals are prone to fall off, moisture absorption, and sticking and agglomeration with utensils during use.

[0105] The medium segments 111 of the aerosol generating matrix 11 provided in the embodiment of the present application are an integrated structure formed by a co-extrusion process, so as to improve the uniformity of the density of the medium segment 111 and improve the stability of aerosol release and suction. In addition, the mass of the medium segment 111 of the integrated structure is relatively uniform. When the heating element heats the medium segment 111, it will not squeeze the structure around the medium segment 111, so that the medium segment 111 maintains a relatively uniform matrix density. Furthermore, the medium segment 111 of the integrated structure is not easy to stick to the aerosol generating device, agglomerate, etc.

[0106] In addition, each medium segment 111 is an integrated structure formed by a co-extrusion process, which can effectively solve the problem of compounding or splicing multiple medium segments 111, shorten the process route, and reduce the quality fluctuation of the aerosol generating matrix 11. The co-extrusion process is simple, low-cost, and does not require the use of additional adhesives, which is more conducive to ensuring the taste of the aerosol generating matrix 11.

[0107] The specific components of the medium segment 111 are not limited herein. For example, in one embodiment, the medium segment 111 may include plant components, auxiliary components, smoke-generating agent components, adhesive components, and flavor components.

[0108] The plant component is used to generate an aerosol when heated. The auxiliary component is used to provide a skeleton support for the plant component. The smoke-generating agent component is used to generate smoke when heated. The adhesive component is used to bond the various raw material components. The flavor component is used to provide a characteristic aroma. In this way, the plant component and the smoke-generating agent component can ensure the amount of aerosol generated, while the flavor component can enhance the release of aroma during the inhalation process and enhance the user experience. The auxiliary component can not only improve the fluidity of the mixed material, but also make the medium segment 111 porous to facilitate the extraction and flow of the aerosol. The adhesive component ensures that the plant component and the auxiliary component etc. constitute a stable mixture to avoid a loose structure.

[0109] Exemplarily, the plant component can be one or more combinations of powders formed after crushing tobacco raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, and flavor plants. Plant components are the core source of flavor. Endogenous substances in plant components can produce physiological satisfaction for users. Endogenous substances such as alkaloids enter the human blood and promote the pituitary gland to produce dopamine, thereby obtaining physiological satisfaction.

[0110] Exemplarily, the auxiliary agent component can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. Among them, the inorganic filler includes one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic filler can provide a skeleton support for the plant component, and the inorganic filler also has micropores, which can increase the porosity of the medium segment 111, thereby increasing the aerosol release rate. The lubricant includes one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. The lubricant can increase the fluidity 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 can also reduce the pressure required for the extrusion molding process and reduce the wear of the die. The emulsifier includes one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. The emulsifier can slow down the loss of flavor substances during storage to a certain extent, increase the stability of the flavor substances, and improve the sensory quality of the product.

[0111] Exemplarily, the smoke-generating agent component may include: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, glycerol, triethylene glycol, 1,3-butylene glycol and tetraethylene glycol); an ester of a polyhydric alcohol (such as triacetin, triethyl citrate, a mixture of diacetin esters, triethyl citrate, benzyl benzoate, glyceryl tributyrate); a monocarboxylic acid; a dicarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butylene glycol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, Triactin, meso-erythritol, a mixture of diacetin esters, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, lauryl acetate) in one or more combinations.

[0112] Exemplarily, the adhesive component is in close contact with the interface of the component raw materials by wetting, generating intermolecular attraction, thereby playing a role in bonding the component raw materials, such as powders, liquids, etc. The adhesive component can be a natural plant extract, a non-ionized modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, guar gum, and modified cellulose (such as carboxymethyl cellulose). The adhesive is used to bond the particles together, which is not easy to loosen. In addition, it improves the water resistance of the medium segment 111 and is harmless to the human body.

[0113] Exemplarily, the flavor component is used to provide a characteristic aroma, such as hay aroma, roasted sweet aroma, solid or liquid substances of nicotine. The flavor component may include one or more combinations of tobacco or other plants, flavor plant extracts, extracts, essential oils, and absolute oils; the flavor component may include monomeric flavor substances, such as one or more combinations of megastigmatriene, neophytadiene, geraniol, nerol, etc.

[0114] In some embodiments, see Figure 1 , the structures of the media segments 111 are the same, and at least some of the media segments 111 are made of different materials. That is, the number of airway holes 11a, the shape of the airway holes 11a, the hydraulic diameter of the airway holes 11a, the cross-sectional area of ​​the airway holes 11a, the arrangement of the airway holes 11a, the shape of the media segments 111, and the cross-sectional area of ​​the media segments 111 are all the same in the media segments 111, and at least some of the media segments 111 are made of different materials.

[0115] Thus, by controlling different medium segments 111 to use different materials, the richness of the aerosol can be improved. By controlling different medium segments 111 to use the same structure, the aerosol generating matrix 11 can release the aerosol more evenly and stably, and the flow rate and / or flow rate of the airflow can be adjusted, thereby improving the user experience.

[0116] Take two media segments 111 as an example, see Figure 1 The two medium segments 111 are extruded by materials of different formulations, that is, the two medium segments 111 are made of different materials, and the number of airway holes 11a, the shape of the airway holes 11a, the hydraulic diameter of the airway holes 11a, the cross-sectional area of ​​the airway holes 11a, the arrangement of the airway holes 11a, the shape of the medium segments 111, and the cross-sectional area of ​​the medium segments 111 are all the same.

[0117] Taking the three medium segments 111 as an example, the three medium segments 111 are all extruded and molded using materials of different formulations, that is, the three medium segments 111 are made of different materials, and the number of airway holes 11a, the shape of the airway holes 11a, the hydraulic diameter of the airway holes 11a, the cross-sectional area of ​​the airway holes 11a, the arrangement of the airway holes 11a, the shape of the medium segments 111, and the cross-sectional area of ​​the medium segments 111 are all the same. This further improves the richness of the aerosol and makes it more plastic.

[0118] In some embodiments, see Figures 2 to 3 , the materials of the media segments 111 are the same, and at least some of the media segments 111 have different structures. That is, the materials of the media segments 111 are the same, and at least some of the media segments 111 have different numbers of airway holes 11a, shapes of the airway holes 11a, hydraulic diameters of the airway holes 11a, cross-sectional areas of the airway holes 11a, arrangements of the airway holes 11a, shapes of the media segments 111, and cross-sectional areas of the media segments 111.

[0119] Thus, by controlling different medium segments 111 to use the same material, the consistency of the aerosol can be improved. By controlling different medium segments 111 to use different structures, the flow rate and / or flow rate of the airflow can be adjusted, the heating uniformity and heating efficiency of the aerosol generating substrate 11 can be improved, and the aerosol can be effectively cooled.

[0120] In a specific embodiment, please refer to Figure 2 , the number of the medium segments 111 is two, and the two medium segments 111 are made of the same material, which can improve the consistency of the aerosol. A through hole 11b is provided at the center of one of the medium segments 111, and the interior of the other medium segment 111 has a plurality of airway holes 11a with the same inner diameter and a circular cross section. In this way, the aerosol can be evenly divided into multiple aerosols through the through hole 11b and enter the airway hole 11a. Such a setting can increase the contact area between the aerosol and the medium segment 111, which is conducive to the precipitation and release of the effective ingredients in the medium segment 111, and is also conducive to increasing the flow rate of the aerosol, thereby improving the cooling effect of the aerosol.

[0121] In another specific embodiment, please refer to Figure 3, the number of the medium segments 111 is three, and the three medium segments 111 are made of the same material, which can improve the consistency of the aerosol. A through hole 11b is set at the center of two of the medium segments 111, and the interior of one of the medium segments 111 has multiple airway holes 11a with the same inner diameter and a circular cross-section, and the two medium segments 111 with through holes 11b are respectively arranged at the two ends of the medium segment 111 with the airway holes 11a. In this way, the aerosol can be evenly divided into multiple aerosols through the through hole 11b at one end of the aerosol generating matrix 11 and enter the airway holes 11a of the middle medium segment 111, and then collected into the through hole 11b at the other end of the aerosol generating matrix 11. Through this arrangement, a Venturi effect can be formed inside the aerosol generating matrix 11, which is more conducive to the flow of aerosol. During the heating process, when the hot aerosol generated by the lower medium segment 111 passes through the middle medium segment 111, the contact specific surface area between the aerosol and the medium segment 111 increases, so that the internal energy in the aerosol can be transferred to the medium segment 111, and the middle medium segment 111 is heated. After flowing out, the aerosol flow rate is reduced, resulting in loss of aerosol internal energy, thereby improving the heating uniformity and heating efficiency of the aerosol generating matrix 11, and can effectively reduce the temperature of the aerosol outflow medium.

[0122] Among them, the Venturi effect is manifested in that when the restricted flow passes through a reduced flow cross-section, the flow velocity of the fluid increases, and its flow velocity is inversely proportional to the flow cross-section.

[0123] In some embodiments, at least some of the media segments 111 are made of different materials, and at least some of the media segments 111 are made of different structures. That is, the materials of the media segments 111 are the same, and at least some of the media segments 111 are different in at least one of the number of airway holes 11a, the shape of the airway holes 11a, the hydraulic diameter of the airway holes 11a, the cross-sectional area of ​​the airway holes 11a, the arrangement of the airway holes 11a, the shape of the media segments 111, and the cross-sectional area of ​​the media segments 111.

[0124] Thus, by controlling different materials of different medium segments 111, the richness of aerosol can be improved. By controlling different structures of different medium segments 111, the flow rate and / or flow rate of the airflow can be adjusted, the heating uniformity and heating efficiency of the aerosol generating substrate 11 can be improved, and the aerosol can be effectively cooled. The plasticity of the aerosol generating substrate 11 is further improved.

[0125] In some embodiments, the aerosol-generating substrate 11 and the functional segment 12 are an integral structure formed by a co-extrusion process.

[0126] The integrated aerosol generating matrix 11 and functional segment 12 can reduce the number of parts, reduce assembly time, improve assembly efficiency, and improve production efficiency. In addition, the aerosol generating matrix 11 and functional segment 12 are an integrated structure formed by a co-extrusion process, which can effectively shorten the process route and reduce the quality volatility of the aerosol generating product 1. The co-extrusion process is simple and low-cost, which is more conducive to ensuring the taste of the aerosol generating product 1.

[0127] In some embodiments, the aerosol-generating substrate 11 and the functional segment 12 are made of the same material.

[0128] The materials of the aerosol generating matrix 11 and the functional segment 12 are both plant materials such as tobacco. The same material can be used to share the same slurry and the same feed port 211a. The difference between the aerosol generating matrix 11 and the functional segment 12 can be achieved by changing the diameter or deformation of the die, which can shorten the process and improve production efficiency.

[0129] In some embodiments, the materials of the aerosol-generating substrate 11 and the functional segment 12 are different.

[0130] Since the material of the aerosol generating matrix 11 generally contains plant materials such as tobacco, the aerosol generating matrix 11 and the functional segment 12 use different materials, which can reduce the use of tobacco components and quantitatively add tobacco endogenous substances (such as nicotine); in addition, the functional segment 12 can use materials such as spice plants and porous molecular sieves to achieve the effects of tobacco flavor supplementation, molecular sieve filtration of harmful substances, etc.

[0131] In some embodiments, the functional segment 12 includes a plurality of monomers sequentially arranged along the first direction, and each monomer is an integrated structure formed by a co-extrusion process.

[0132] That is to say, the functional segment 12 is a multi-segment structure, that is, the functional segment 12 includes multiple monomers, and the monomers are arranged sequentially in the first direction. The structures and / or materials of at least some of the monomers are different. In this way, the structure and / or material of each monomer can be set as needed, and the functional segment 12 has stronger plasticity. By regulating the structure and / or material of the monomer, the functional segment 12 can achieve cooling and / or support and / or filtering and / or adjustment of the suction resistance, thereby improving the user experience.

[0133] In some embodiments, see Figures 4 to 6, the wrapping layer 13 and at least one of the aerosol generating substrate 11 and the functional segment 12 are an integral structure formed by a co-extrusion process. For example, the wrapping layer 13 and the aerosol generating substrate 11 may be an integral structure formed by a co-extrusion process, the wrapping layer 13 and the functional segment 12 may be an integral structure formed by a co-extrusion process, or the wrapping layer 13 and the aerosol generating substrate 11 and the functional segment 12 may all be an integral structure formed by a co-extrusion process.

[0134] The wrapping layer 13 and at least one of the aerosol generating substrate 11 and the functional segment 12 are an integrated structure, which can reduce assembly time, improve assembly efficiency, and improve production efficiency. In addition, the wrapping layer 13 and at least one of the aerosol generating substrate 11 and the functional segment 12 are an integrated structure formed by a co-extrusion process, which can effectively shorten the process route and reduce the quality volatility of the aerosol generating product 1. The co-extrusion process is simple and low-cost, which is more conducive to ensuring the taste of the aerosol generating product 1.

[0135] That is to say, the consumable structures of the aerosol generating product 1 can all be an integrated structure formed by a co-extrusion process, and various consumable structures can also be an integrated structure formed by a co-extrusion process.

[0136] The consumable structure includes an aerosol generating matrix 11 , a functional segment 12 and a wrapping layer 13 .

[0137] In some embodiments, see Figure 6 The aerosol generating article 1 comprises an aerosol generating substrate 11 and a functional segment 12. The aerosol generating substrate 11 comprises a plurality of dielectric layers 112. The plurality of dielectric layers 112 are mounted one by one along the inner and outer directions. Each dielectric layer 112 is an integral structure formed by a co-extrusion process. The functional segment 12 is disposed at one end of the aerosol generating substrate 11 along a first direction. The functional segment 12 and the aerosol generating substrate 11 are an integral structure formed by a co-extrusion process.

[0138] In this way, the raw material combination ratios of each medium layer 112 are different, and different flavor combinations can be achieved to enrich the user experience, and the internal structures can be the same or different.

[0139] In some embodiments, the aerosol generating product 1 further comprises a wrapping layer 13, which wraps around the outer periphery of the functional segment 12 and the aerosol generating matrix 11, and the wrapping layer 13, the aerosol generating matrix 11 and the functional segment 12 are an integrated structure formed by a co-extrusion process.

[0140] The wrapping layer 13, the aerosol generating matrix 11 and the functional segment 12 are an integrated structure, which can reduce assembly time, improve assembly efficiency, and improve production efficiency. In addition, the wrapping layer 13, the aerosol generating matrix 11 and the functional segment 12 are an integrated structure formed by a co-extrusion process, which can effectively shorten the process route and reduce the quality volatility of the aerosol generating product 1. The co-extrusion process is simple and low in cost, which is more conducive to ensuring the taste of the aerosol generating product 1.

[0141] In some embodiments, see Figures 4 to 5 The functional section 12 includes a cooling section 121 and a filtering section 122 located at one end of the cooling section 121 away from the aerosol generating substrate 11. The aerosol generating substrate 11, the cooling section 121 and the filtering section 122 are an integrated structure formed by a co-extrusion process.

[0142] The aerosol generating matrix 11, the cooling section 121 and the filtering section 122 are an integrated structure, which can reduce assembly time, improve assembly efficiency, and improve production efficiency. In addition, the aerosol generating matrix 11, the cooling section 121 and the filtering section 122 are an integrated structure formed by a co-extrusion process, which can effectively shorten the process route and reduce the quality volatility of the aerosol generating product 1. The co-extrusion process is simple and low in cost, which is more conducive to ensuring the taste of the aerosol generating product 1.

[0143] A fourth aspect of the present application provides a manufacturing device 2, see Figures 7 and 8 The manufacturing equipment 2 includes an extruder 21, a common die head 22 and a first molding die head 23. The extruder 21 includes a plurality of barrels 211, each of which is provided with a feed port 211a and a discharge port 211b. The common die head 22 has a first connection port 22a and a plurality of second connection ports 22b, each of which is connected to the first connection port 22a, and each second connection port 22b corresponds to and is connected to each discharge port 211b. The first molding die head 23 is connected to the first connection port 22a.

[0144] Specifically, extrusion molding refers to a processing method in which materials are added to an extruder 21, and the materials are pushed forward by the screw through the action between the barrel 211 and the screw of the extruder 21, and continuously pass through the common die 22 and the first molding die 23 at the discharge port 211b of the extruder 21 to form various cross-sectional products or semi-finished products.

[0145] The number of barrels 211 is not limited herein, for example, it can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or 13, etc.

[0146] The common die 22 is used to connect the first molding die 23 and the extruder 21. The common die 22 is provided with a first connection port 22a and a plurality of second connection ports 22b, each second connection port 22b corresponds to and is connected to each discharge port 211b, and the first molding die 23 is connected to the first connection port 22a.

[0147] The barrel 211 is used for feeding and extrusion. The mixed material enters the barrel 211 through the feeding port 211 a and enters the common die 22 and the first molding die 23 through the discharge port 211 b of the barrel 211 .

[0148] Different materials in each barrel 211 can be sequentially extruded to the common die 22 and the first molding die 23 through a twin screw or the like to form an extruded monomer, and the extruded monomer is spliced ​​axially or radially in the first molding die 23. In this way, intermittent feeding and extrusion can be performed through each barrel 211 to achieve a co-extrusion process to extrude a plurality of different materials of the medium segment 111 and / or the functional segment 12 and / or the wrapping layer 13 to form an integrated structure. In addition, the structure of the medium segment 111 and / or the functional segment 12 and / or the wrapping layer 13 can be changed by adjusting the core of the first molding die 23.

[0149] For example, the manufacturing equipment 2 is used to manufacture Figure 1 In the case of the aerosol-generating matrix 11 having two medium segments 111, the two medium segments 111 have the same structure but different materials. Thus, the manufacturing device 2 having two barrels 211 can be used. The materials of the two medium segments 111 are added to the two barrels 211 respectively, extruded to the common die 22 through a twin screw, and formed and discharged from the same forming die 23, and then spliced. The manufacturing device 2 can intermittently extrude and splice multiple medium segments 111 by setting a certain automatic control program, and use the common die 22 and the first forming die 23 to achieve co-extrusion.

[0150] For example, when the manufacturing device 2 is used to manufacture the aerosol generating matrix 11 of the medium segment 111 and the functional segment 12, and the medium segment 111 and the functional segment 12 have the same structure but different materials, the manufacturing device 2 having two barrels 211 can be used, and the materials of the medium segment 111 and the functional segment 12 are added to the two barrels 211 respectively, and extruded to the common die 22 through a twin screw, and the materials are formed and discharged from the same molding die first molding die 23, and then spliced. The manufacturing device 2 can intermittently extrude and splice the medium segment 111 and the functional segment 12 by setting a certain automatic control program, and use the common die 22 and the first molding die 23 to achieve co-extrusion.

[0151] In some embodiments, the extruder 21 further includes a plurality of second molding dies (not shown), each of which is disposed between each discharge port 211 b and the common die 22 .

[0152] In this way, a second molding die can be set between each discharge port 211b and the common die 22 so that the medium segment 111 and / or the functional segment 12 and / or the wrapping layer 13 can be molded into a desired structure through the second molding die and then spliced ​​at the first molding die 23.

[0153] In some embodiments, at least one of the second molding dies is of a different type than the other second molding dies.

[0154] In this way, different second molding dies can be set between each discharge port 211b and the common die 22 according to the required shape, so that the medium segment 111 and / or the functional segment 12 and / or the wrapping layer 13 can be molded into the required structure through the second molding die, and then spliced ​​at the first molding die 23.

[0155] For example, when the manufacturing device 2 is used to manufacture an aerosol-generating matrix 11 having multiple medium segments 111, and the structures of the multiple medium segments 111 are different, the manufacturing device 2 having multiple barrels 211 can be used, and the materials of the medium segments 111 are added to the multiple barrels 211 respectively, and extruded to the second molding die head through a twin screw to form a desired shape, and discharged through the common die head 22 and the first molding die head 23, and spliced. The manufacturing device 2 can intermittently extrude and splice multiple sections of the medium segment 111 by setting a certain automatic control program, and use the second molding die head, the common die head 22 and the first molding die head 23 to achieve co-extrusion.

[0156] For example, when the manufacturing device 2 is used to manufacture an aerosol-generating matrix 11 having a medium segment 111 and a functional segment 12, and the structures of the medium segment 111 and the functional segment 12 are different, the manufacturing device 2 having multiple barrels 211 can be used, and the materials of the medium segment 111 and the functional segment 12 are added to the multiple barrels 211 respectively, and extruded to the second molding die head through a twin screw to form a desired shape, and discharged through the common die head 22 and the first molding die head 23, and spliced. The manufacturing device 2 can intermittently extrude and splice the medium segment 111 and the functional segment 12 by setting a certain automatic control program, and use the second molding die head, the common die head 22 and the first molding die head 23 to achieve co-extrusion.

[0157] The fifth aspect of the embodiment of the present application provides a manufacturing device (not shown), wherein the manufacturing device 2 is provided with an extruder 21. The extruder 21 includes a barrel 211 and a first molding die 23. The barrel 211 is provided with a feed port 211a and a discharge port 211b. The first molding die 23 includes an extrusion channel and a plurality of cores arranged in the extrusion channel, the extrusion channel is connected to the discharge port 211b, and the arrangement mode and / or size and / or shape of each core is adjustable.

[0158] The barrel 211 is used for feeding and extrusion. The mixed material enters the barrel 211 through the feeding port 211a, and enters the first molding die 23 through the discharge port 211b of the barrel 211 for extrusion molding.

[0159] The arrangement and / or size and / or shape of each mold core can be adjusted. For example, the arrangement and / or size and / or shape of each mold core can be automatically adjusted by an automatic control device, so that extrusion monomers with different airway hole 11a arrangements, airway hole 11a sizes and airway hole 11a shapes can be obtained.

[0160] The arrangement mode and / or size and / or shape of each mold core are adjustable, that is, the arrangement mode of each mold core in the extrusion channel can be adjusted, the size of the mold core can be adjusted, and the shape of the mold core can be adjusted, so as to obtain medium segments 111 and / or functional segments 12 and / or wrapping layers 13 of different structures. The manufacturing device 2 can be applicable to medium segments 111 and / or functional segments 12 of the same material, and only one barrel 211 is required. The difference between the medium segments 111 and / or functional segments 12 is achieved by changing the diameter or deformation of the mold core, so as to achieve the molding of medium segments 111 and functional segments 12 of different structures, and realize the co-extrusion molding of the aerosol generating matrix 11 formed by the combination of 1+1 or 1+N by sharing the first molding die head 23, which can shorten the process flow and improve the extrusion efficiency.

[0161] For example, when the manufacturing equipment 2 is used to manufacture an aerosol generating matrix 11 having multiple medium segments 111, and the multiple medium segments 111 have different structures but the same materials, the manufacturing equipment 2 can be used to add materials into the barrel 211, and the materials are extruded to the first molding die 23 through a twin-screw extruder to form and discharge the materials, and then the arrangement and / or size and / or shape of each mold core is automatically adjusted through an automatic control device to achieve the molding of medium segments 111 with different structures and to perform splicing.

[0162] For example, when the manufacturing equipment 2 is used to manufacture an aerosol generating matrix 11 having a medium segment 111 and a functional segment 12, and the medium segment 111 and the functional segment 12 have different structures but the same materials, the manufacturing equipment 2 can be used to add materials into the barrel 211, and the materials are extruded to the first molding die 23 through a twin-screw extruder to form the medium segment 111, and then the arrangement and / or size and / or shape of each mold core is automatically adjusted through an automatic control device to realize the molding of functional segments 12 with different structures and to perform splicing.

[0163] A sixth aspect of the present application provides a manufacturing method for manufacturing equipment 2, see Figure 7 and Figure 8The manufacturing device 2 is provided with an extruder 21, which includes a plurality of barrels 211, a common die head 22 and a first molding die head 23. The first molding die head 23 is connected to the plurality of barrels 211 through the common die head 22. Fig. 9 , the manufacturing method comprises:

[0164] S100: Adding material step, adding different mixed materials into each barrel respectively;

[0165] S200: conveying step, conveying, shearing and melting the mixed material through a screw;

[0166] S300: extrusion step, controlling different mixed materials to be extruded through the common die and the first molding die 23 in sequence to form different extrusion monomers;

[0167] S400: a splicing step of controlling different extrusion monomers to be spliced ​​along a first direction in a first molding die.

[0168] Specifically, extrusion molding refers to a processing method in which materials are added to an extruder 21, and the materials are pushed forward by the screw through the action between the barrel 211 and the screw of the extruder 21, and continuously pass through the common die 22 and the first molding die 23 at the discharge port 211b of the extruder 21 to form various cross-sectional products or semi-finished products.

[0169] The number of barrels 211 is not limited herein, for example, it can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or 13, etc.

[0170] The common die 22 is used to connect the first molding die 23 and the extruder 21. The common die 22 is provided with a first connection port 22a and a plurality of second connection ports 22b, each second connection port 22b corresponds to and is connected to each discharge port 211b, and the first molding die 23 is connected to the first connection port 22a.

[0171] The barrel 211 is used for feeding and extrusion. The mixed material enters the barrel 211 through the feeding port 211 a and enters the common die 22 and the first molding die 23 through the discharge port 211 b of the barrel 211 .

[0172] In step S100 , different mixed materials may be added into each barrel 211 according to the types of constituent materials of the required extruded monomer.

[0173] In step S200, the mixed material is conveyed, sheared and melted by a screw in preparation for extrusion.

[0174] In step S300 , the manufacturing device 2 can intermittently extrude multiple medium segments 111 and / or functional segments 12 by setting a certain automatic control program.

[0175] In step S400 , different extrusion units (which may be multiple medium segments 111 and / or multiple functional segments 12 and / or wrapping layers 13 ) are controlled to be spliced ​​along a first direction in the first molding die 23 .

[0176] Different materials in each barrel 211 can be sequentially extruded to the common die 22 and the first molding die 23 through a twin screw or the like to form an extruded monomer, and the extruded monomer is spliced ​​axially or radially in the first molding die 23. In this way, intermittent feeding and extrusion can be performed through each barrel 211 to achieve a co-extrusion process to extrude a plurality of different materials of the medium segment 111 and / or the functional segment 12 and / or the wrapping layer 13 to form an integrated structure. In addition, the structure of the medium segment 111 and / or the functional segment 12 and / or the wrapping layer 13 can be changed by adjusting the core of the first molding die 23.

[0177] In some embodiments, the extruder 21 further includes a plurality of second molding dies, each of which is disposed between the discharge port 211b of each barrel 211 and the common die 22, at least one of which is of a different type from the other second molding dies, and controlling different mixed materials to be extruded through the common die 22 and the first molding die 23 in sequence to form different extrusion monomers specifically includes:

[0178] The different mixed materials are controlled to be extruded through the second molding die, the common die 22 and the first molding die 23 in sequence to form different extrusion monomers.

[0179] In this way, a second molding die can be set between each discharge port 211b and the common die 22 so that the medium segment 111 and / or the functional segment 12 and / or the wrapping layer 13 can be molded into a desired structure through the second molding die and then spliced ​​at the first molding die 23.

[0180] At least one of the second molding dies is of a different type from the other second molding dies. Thus, different second molding dies can be arranged between each outlet 211b and the common die 22 according to the required shape, so that the medium segment 111 and / or the functional segment 12 and / or the wrapping layer 13 are molded into the required structure through the second molding die and then spliced ​​at the first molding die 23.

[0181] For example, when the manufacturing device 2 is used to manufacture an aerosol-generating matrix 11 having multiple medium segments 111, and the structures of the multiple medium segments 111 are different, the manufacturing device 2 having multiple barrels 211 can be used, and the materials of the medium segments 111 are added to the multiple barrels 211 respectively, and extruded to the second molding die head through a twin screw to form a desired shape, and discharged through the common die head 22 and the first molding die head 23, and spliced. The manufacturing device 2 can intermittently extrude and splice multiple sections of the medium segment 111 by setting a certain automatic control program, and use the second molding die head, the common die head 22 and the first molding die head 23 to achieve co-extrusion.

[0182] For example, when the manufacturing device 2 is used to manufacture an aerosol-generating matrix 11 having a medium segment 111 and a functional segment 12, and the structures of the medium segment 111 and the functional segment 12 are different, the manufacturing device 2 having multiple barrels 211 can be used, and the materials of the medium segment 111 and the functional segment 12 are added to the multiple barrels 211 respectively, and extruded to the second molding die head through a twin screw to form a desired shape, and discharged through the common die head 22 and the first molding die head 23, and spliced. The manufacturing device 2 can intermittently extrude and splice the medium segment 111 and the functional segment 12 by setting a certain automatic control program, and use the second molding die head, the common die head 22 and the first molding die head 23 to achieve co-extrusion.

[0183] In a specific embodiment, please refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 The entire consumable structure in this embodiment is realized by co-extrusion, and is composed of a medium section 111, a cooling section 121, and a filtering section 122 starting from the far lip end. Three extruders 21 are used to supply three different materials respectively, and three different head molds are used to extrude and mold them respectively, and then to a common die 22; by setting a certain automatic control program, multiple sections of the medium section 111 are intermittently extruded and spliced, and co-extrusion is realized using a common die 22 and displacement molding.

[0184] The seventh aspect of the embodiment of the present application provides a manufacturing method, which is applied to a manufacturing device 2, wherein the manufacturing device 2 is provided with an extruder 21, the extruder 21 includes a barrel 211 and a first molding die 23, the first molding die 23 includes an extrusion channel and a plurality of mold cores arranged in the extrusion channel, the extrusion channel is connected to the discharge port 211b of the barrel 211, and the arrangement mode and / or size and / or shape of each mold core are adjustable, see Fig.10 , the manufacturing method comprises:

[0185] S1000: Adding material step, adding mixed material into the barrel;

[0186] S2000: conveying step, conveying, shearing and melting the mixed material through the screw;

[0187] S3000: an adjustment step, adjusting the arrangement and / or size and / or shape of each mold core;

[0188] S4000: extrusion step, controlling the mixed material to be extruded through a first molding die to form an extrusion monomer;

[0189] S5000: a splicing step, repeating the adjustment step and the extrusion step until a plurality of required extrusion monomers are obtained, and splicing the extrusion monomers along a first direction in a first molding die.

[0190] The barrel 211 is used for feeding and extrusion. The mixed material enters the barrel 211 through the feeding port 211a, and enters the first molding die 23 through the discharge port 211b of the barrel 211 for extrusion molding.

[0191] The arrangement and / or size and / or shape of each mold core can be adjusted. For example, the arrangement and / or size and / or shape of each mold core can be automatically adjusted by an automatic control device, so that extrusion monomers with different airway hole 11a arrangements, airway hole 11a sizes and airway hole 11a shapes can be obtained.

[0192] The arrangement mode and / or size and / or shape of each mold core are adjustable, that is, the arrangement mode of each mold core in the extrusion channel can be adjusted, the size of the mold core can be adjusted, and the shape of the mold core can be adjusted, so as to obtain medium segments 111 and / or functional segments 12 and / or wrapping layers 13 of different structures. The manufacturing device 2 can be applicable to medium segments 111 and / or functional segments 12 of the same material, and only one barrel 211 is required. The difference between the medium segments 111 and / or functional segments 12 is achieved by reducing the diameter or deforming the mold core, so as to achieve the molding of medium segments 111 and functional segments 12 of different structures. By repeating the adjustment step and the extrusion step, the co-extrusion molding of the aerosol generating matrix 11 formed by the combination of 1+1 or 1+N by sharing the first molding die head 23 can be achieved, which can shorten the process flow and improve the extrusion efficiency.

[0193] For example, when the manufacturing equipment 2 is used to manufacture an aerosol generating matrix 11 having multiple medium segments 111, and the multiple medium segments 111 have different structures but the same materials, the manufacturing method can be used to add materials into the barrel 211, extrude the materials to the first molding die 23 through a twin-screw extruder, and then automatically adjust the arrangement and / or size and / or shape of each mold core through an automatic control device to achieve the molding of medium segments 111 with different structures and perform splicing.

[0194] For example, when the manufacturing equipment 2 is used to manufacture an aerosol generating matrix 11 having a medium segment 111 and a functional segment 12, and the medium segment 111 and the functional segment 12 have different structures but the same materials, the manufacturing method can be used to add materials into the barrel 211, and the materials are extruded through a twin-screw extruder to the first molding die 23 to form the medium segment 111, and then the arrangement and / or size and / or shape of each mold core is automatically adjusted by an automatic control device to achieve the molding of functional segments 12 with different structures and to perform splicing.

[0195] In a specific embodiment, please refer to Figure 6 The consumables have a three-component structure, which consists of a medium section 111, a hollow section, and a filter section 122 starting from the far lip end, and the outer layer is coated with a paper tube. The entire consumable is realized by a two-time co-extrusion process, wherein the medium section 111 is supplied with three different material flows by three extruders 21, which are respectively combined on a composite die to realize radial three-phase combination molding (specifically, each phase is shaped by a pre-forming mold, and then combined by a shaping mold). At the same time, one extruder 21 is used to extrude the hollow section and the filter section 122, which are respectively shaped and pre-cut, and are arranged in order by a discharge device, and then the pre-arranged medium is pushed out from the center hole of the mold through the hollow mold. At the same time, continuous feeding is used to extrude the outer layer to realize the coating of the pre-arranged medium. The outer layer coating material can be pulp flow, PLA, high temperature resistant plastic, light absorbing, thermal conductive material or other materials. The advantage of this is that the entire consumable manufacturing process is shortened, and the manufacturing cost is effectively reduced.
