Description

Technical Field

[0001] This application relates to the field of smoke-generating products, and in particular to a functional segment, an aerosol-generating product, and an aerosol-generating system. Background Technology

[0002] Aerosol-generating products consist of a matrix segment and a functional segment. The matrix segment is heated by an external heat source to form an aerosol.

[0003] In related technologies, aerosol-generated products use functional segments to carry fragrance in order to improve taste, mask odors, and enhance product appeal. However, the fragrance diffusion uniformity is poor and the fragrance layering is low, making it difficult to meet the different fragrance needs of different consumers at the same time. Therefore, it is necessary to optimize the structure of the functional segments. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide a functional segment, an aerosol generating article, and an aerosol generating system to increase the uniformity of aroma diffusion and the layering of aroma, thereby enhancing the user experience.

[0005] This application provides a functional segment for use in aerosol generation products. The functional segment is an integral structure and includes multiple splicing segments. The multiple splicing segments are spliced ​​together along the circumferential direction of the functional segment. At least two of the splicing segments are made of different materials, and at least one of the splicing segments is loaded with a fragrance substance.

[0006] In some implementation schemes, any two adjacent splicing segments in a plurality of splicing segments are made of different materials.

[0007] In some implementations, the functional segment is a one-piece co-extruded structure; and / or, the outer contour of the functional segment is a columnar structure.

[0008] In some implementations, the at least one splicing segment is provided with at least one through hole that extends axially through the splicing segment.

[0009] In some embodiments, the number of through holes is multiple, including a first through hole and a second through hole. The splicing segment includes a first part and a second part that are connected to each other in the radial direction. The first through hole is disposed in the first part, and the second through hole is disposed in the second part. The first through hole and the second through hole are different in size and / or shape.

[0010] In some embodiments, the splicing segment includes an inner wall and an outer wall disposed opposite each other in a radial direction, and the outer walls of each splicing segment are spliced ​​together to form the outer contour of the functional segment;

[0011] The inner walls of each splicing segment are spaced apart to enclose a hollow channel within the functional segment;

[0012] Alternatively, the inner walls of each of the splicing segments may be spliced ​​together.

[0013] In some implementations, the number of splicing segments is two, and the ratio of the projected areas of the two splicing segments in the plane projection of the functional segment perpendicular to the axis is 1 to 4.

[0014] Alternatively, the number of splicing segments is at least three, and the projected area of ​​each splicing segment is approximately the same in the plane projection of the functional segment along the axis perpendicular to the axis.

[0015] In some implementations, the splicing segments are bonded together by non-covalent bonds.

[0016] This application provides an aerosol generating article, comprising:

[0017] A matrix segment for generating aerosols, the matrix segment comprising a distal lip end and a proximal lip end disposed opposite each other along an axial direction;

[0018] And the functional segment described in any embodiment of this application, wherein the functional segment is disposed at the proximal lip end and / or the distal lip end.

[0019] In some implementations, the number of the functional segments is multiple, with at least one functional segment disposed at the proximal lip end and at least one functional segment disposed at the distal lip end;

[0020] And / or, the aerosol-generating article includes an encapsulation layer that encapsulates the periphery of at least a portion of the structure of the matrix segment and the functional segment.

[0021] This application provides an aerosol generation system, including:

[0022] Aerosol generating apparatus, including heating components;

[0023] And the aerosol generating article described in any embodiment of this application, wherein the matrix segment generates aerosol under the heating action of the heating component.

[0024] The functional segment provided in this application embodiment is composed of multiple spliced ​​segments along the circumferential direction, with at least two spliced ​​segments made of different materials. This allows the fragrance substances to be concentrated in specific areas of the corresponding spliced ​​segments, improving the controllability of fragrance release. Furthermore, it facilitates the zoned release of different fragrance substances, eliminating the need to mix them in one area and allowing users to experience the dynamic changes in fragrance during inhalation. Simultaneously, the functional segment is integrally molded, resulting in high structural stability and reducing assembly steps. In embodiments where the heating component and the aerosol generating product rotate and cooperate, the functional segment of this application embodiment also facilitates instant inhalation and cessation of inhalation, ensuring freshness with each puff and enhancing the inhalation experience.

[0048] Please see Figures 1 to 12 This application provides a functional segment 10, which is applied to an aerosol generating product 100.

[0049] The aerosol generating article 100 includes a matrix segment 20. The matrix segment 20 is used to generate aerosols and may be composed of tobacco or herbal media. The molding method of the matrix segment 20 is not limited; exemplarily, the matrix segment 20 may be a one-piece extruded structure.

[0050] The matrix segment 20 can be heated by a heating component to generate aerosol, in which case the aerosol generating product 100 is a non-combustible aerosol generating product when heated; the matrix segment 20 can also be ignited to generate aerosol, in which case the aerosol generating product 100 is a combustible aerosol generating product.

[0051] For example, in an embodiment where the aerosol generating article 100 generates aerosol by heating without combustion, the matrix segment 20 can be used in conjunction with an aerosol generating device, which includes a heating component and a power supply component. The power supply component provides electrical energy to the heating component, and the heating component converts the electrical energy into other forms of energy and applies them to the matrix segment 20, thereby heating the matrix segment 20 to generate aerosol.

[0052] There are various heating methods for the heating components. For example, heating methods include center heating and peripheral heating. Center heating refers to the heating component being inserted into the matrix segment 20 to bake and heat the matrix segment 20 from the inside out. Peripheral heating refers to the heating component being positioned around the aerosol-generating article 100 to bake and heat the matrix segment 20 from the outside in. These heating methods can specifically include resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc., and are not limited herein.

[0053] The matrix segment 20 includes a distal lip end and a proximal lip end arranged opposite each other along the axial direction. The proximal lip end refers to the end of the matrix segment 20 that is close to the user's lips when the user uses the aerosol generating article 100, and the distal lip end refers to the end of the matrix segment 20 that is far away from the user's lips when the user uses the aerosol generating article 100.

[0054] Functional segment 10 is used to be disposed opposite to the distal lip end and / or opposite to the proximal lip end. This means that, in the embodiments of this application, functional segment 10 may be disposed only at the distal lip end of matrix segment 20, or only at the proximal lip end of matrix segment 20, or it may be disposed at both the proximal lip end and the distal lip end of matrix segment 20.

[0055] Functional segment 10 is an integral structure. Functional segment 10 includes multiple splicing segments 11. The multiple splicing segments 11 are spliced ​​together along the circumferential direction of functional segment 10. At least two splicing segments 11 are made of different materials, and at least one splicing segment 11 is loaded with a fragrance substance.

[0056] At least two splicing segments 11 are made of different materials. This could mean that all splicing segments 11 are made of different materials, or that only some splicing segments 11 are made of different materials. For example, when there are two splicing segments 11, the two splicing segments 11 are made of different materials; when there are three splicing segments 11, all three splicing segments 11 can be made of different materials, or two of the splicing segments 11 can be made of the same material, but different from the material of the other splicing segment 11.

[0057] Preferably, any two adjacent splicing segments 11 are made of different materials. For example, when there are three splicing segments 11, all three segments are made of different materials; when there are four splicing segments 11, all four segments may be made of different materials, or two adjacent segments may be made of different materials, while opposite segments may be made of the same material. This ensures that each splicing segment 11 has the same structure.

[0058] The fact that at least two splicing segments 11 are made of different materials means that at least two splicing segments 11 are manufactured using materials with different physical or chemical properties. These differences include, but are not limited to, properties such as density, hardness, elasticity, thermal stability, and chemical composition. The components of at least two splicing segments 11 may be completely different or partially different, but the final structure formed is made of different materials. That is, the functional segment 10 is a composite material structure.

[0059] It should be noted that the structural features formed by each splicing segment 11 can be the same or different, and the surface area of ​​each splicing segment 11 can be the same or different, without any restrictions.

[0060] Multiple splicing segments 11 are spliced ​​together along the circumferential direction of the functional segment 10, meaning that each splicing segment 11 is spliced ​​along the circumferential direction of the outer contour of the functional segment 10. The outer contours of each splicing segment 11 are combined to form the outer contour of the functional segment 10. That is, the outer wall of the functional segment 10 is defined by the outer walls 111 of each splicing segment 11, and the inner wall of the functional segment 10 is defined by the inner walls 112 of each splicing segment 11. The thickness of the functional segment 10 can be the thickness of a single splicing segment 11.

[0061] It should be noted that in this embodiment, the splicing segments 11 are arranged along the circumferential direction of the functional segment 10, which does not mean that the splicing segments 11 are physically connected after manufacturing. Rather, it means that during the design phase, the internal structure of the functional segment 10 is conceived as having at least two splicing segments 11 made of different materials. These splicing segments 11 are considered separately in the design and then the functional segment 10 is formed in one piece. That is, the functional segment 10 in this embodiment does not have any splicing installation marks in its structure. The connecting lines between the splicing segments 11 in the accompanying drawings of this embodiment are only for illustrative purposes to distinguish the splicing segments 11.

[0062] For example, the functional segment 10 in the embodiments of this application can be formed by two-color injection molding, die casting, or co-extrusion molding.

[0063] The number of splicing segments 11 can be two, three or more, and there is no limit here.

[0064] At least one splicing segment 11 is loaded with a fragrance substance and is integrally formed with the fragrance substance, that is, the functional segment 10 contains the fragrance substance as soon as it is formed. Here, it can be that one splicing segment 11 is loaded with a fragrance substance, or that at least two of a plurality of splicing segments 11 are loaded with a fragrance substance, or that each splicing segment 11 is loaded with a fragrance substance, and there is no limitation here.

[0065] At least one splicing segment 11 is loaded with a fragrance substance, meaning that the splicing segment 11 has been pre-loaded and integrated with a specific fragrance substance, and the fragrance substance has become an integral part of the splicing segment 11. The fragrance substances loaded on each splicing segment 11 may be the same or different, and there is no restriction on this.

[0066] For example, each splicing segment 11 is loaded with a fragrance substance. The fragrance substances loaded on each splicing segment 11 may be the same or different, and there is no limitation on this.

[0067] Specifically, during the manufacturing process, the fragrance substance is directly mixed with other materials to form a slurry, which is then molded using an integrated molding process. This results in the final splicing segment 11 containing not only the substrate as a carrier but also the aroma-emitting components. This approach ensures, on the one hand, that the fragrance substance is evenly distributed and firmly bound within the splicing segment 11, providing a stable and long-lasting aroma release effect. It reduces the complexity and unevenness of adding fragrance substances after molding through coatings or other methods, contributing to improved product quality and consistency. On the other hand, the different materials used in the splicing segment 11 facilitate compatibility with the fragrance substance, concentrating it in specific areas and increasing the uniformity of fragrance diffusion. When different fragrance substances are loaded onto each splicing segment 11, the different materials adapt to the characteristics of different fragrance substances. This allows for optimization of the aroma release rate and duration when the heating component heats the aerosol to generate the product, increasing the uniformity of aroma release and providing different fragrances in different areas, enhancing the aroma's complexity and thus improving the user experience.

[0068] In addition, in embodiments where the heating component and the aerosol generating article 100 rotate in conjunction, the heating component can rotate relative to the aerosol generating article 100, or the aerosol generating article 100 can rotate relative to the heating component. Thus, during the inhalation process of one aerosol generating article 100, the heating component can first heat the area corresponding to one splicing segment 11, then heat the area corresponding to the next splicing segment 11, and so on. When corresponding to one splicing segment 11, it will not affect another splicing segment 11. In this way, the aerosol inhaled each time is fresh. When the aroma substances loaded on each splicing segment 11 are different, the flavor of the inhaled aerosol will also be different when switching to the next splicing segment 11 for inhalation. Users can experience the dynamic changes in aroma during inhalation, increasing the fun of inhalation.

[0069] Understandably, compared to related technologies where fragrance substances are loaded through a matrix segment, in this application, fragrance substances are loaded through a functional segment 10 and integrally formed with the fragrance substances. The fragrance substances release their fragrance through heat transferred from the matrix segment 20. The longer heating time will not cause excessive release of low-boiling-point fragrance substances, thus increasing fragrance consistency. At the same time, the fragrance substances are evenly distributed in each splicing segment 11. If different fragrance substances are present, they can be evenly distributed in different splicing segments 11 without being mixed in the same splicing segment 11. This not only helps to increase fragrance diversity and enhance the fragrance base tone, but also increases the content of fragrance substances loaded in the functional segment 10.

[0070] The types of flavoring substances can include mint flavor, sweet orange flavor, tobacco flavor, etc., and there are no restrictions here.

[0071] The functional segment 10 provided in this embodiment comprises multiple spliced ​​segments 11 joined along the circumferential direction, with at least two spliced ​​segments 11 made of different materials. This allows the fragrance substances to be concentrated in specific areas of the corresponding spliced ​​segments 11, improving the controllability of fragrance release. Furthermore, it facilitates the zoned release of different fragrance substances, enhancing the overall fragrance tone without mixing different fragrance substances in one area, allowing users to experience the dynamic changes in fragrance during inhalation. Simultaneously, the functional segment 10 is integrally molded, resulting in high structural stability and reducing assembly steps. In embodiments where the heating component and the aerosol generating product rotate and cooperate, the functional segment 10 of this embodiment also facilitates immediate inhalation and cessation of inhalation, ensuring freshness with each puff and improving the inhalation experience.

[0072] For example, the aerosol generating article 100 may include at least one of a pre-plug section, a cooling section, a support section, and a filter section. The pre-plug section is located at the distal lip end of the matrix section 20. The pre-plug section reduces the likelihood of the matrix section 20 falling off after heating and also adsorbs the condensate formed by aerosol condensation, reducing the likelihood of condensate escaping from the aerosol generating article 100 and contaminating the aerosol generating device. It also increases suction resistance, resulting in a more reasonable aerosol content per unit time and improving the user experience. The cooling section, support section, and filter section are sequentially arranged along the direction from the distal lip end to the proximal lip end of the matrix section 20. The positions of the cooling section and the support section can be interchanged. The support section serves as a structural connection between the two ends. The cooling section lowers the temperature of the aerosol, ensuring that the temperature of the aerosol flowing out of the aerosol generating article 100 is suitable. The filter section filters the aerosol particles, improving their taste.

[0073] In this embodiment of the application, a functional segment 10 can replace any one or more of the foreplug segment, cooling segment, support segment, and filter segment to perform its corresponding function.

[0074] For example, when the functional segment 10 is located at the distal lip end of the matrix segment 20, the functional segment 10 can be formed as a pre-plug segment, performing its corresponding function as a pre-plug segment. When the functional segment 10 is located at the proximal lip end of the matrix segment 20, the functional segment 10 can be formed as any one of a cooling segment, a support segment, or a filtering segment, performing its corresponding function. When there are multiple functional segments 10, multiple functional segments 10 can respectively replace the pre-plug segment, cooling segment, support segment, and filtering segment. In this embodiment, each splicing segment 11 is designed only with reference to the structure to be replaced. The functions of each splicing segment 11 are the same, and the structures of each splicing segment 11 are the same. Here, "same structure" does not mean that the surface areas of each splicing segment 11 must be the same; the surface areas of each splicing segment 11 can be the same or different.

[0075] For example, when the functional segment 10 is located near the lip end of the matrix segment 20, the multiple splicing segments 11 can be designed with reference to the structure and function of any at least two of the cooling segment, support segment, and filter segment. The functions of the multiple splicing segments 11 are not the same, so that the formed functional segment 10 can simultaneously have the functions of any at least two of the cooling segment, support segment, and filter segment.

[0076] For example, please refer to Figures 1 to 8 Functional segment 10 has a mirror-symmetric structure.

[0077] Mirror symmetry refers to the phenomenon that an object or shape can perfectly overlap with itself after being reflected by a plane of symmetry.

[0078] In this embodiment, the functional segment 10 is formed with a mirror-symmetric structure, which can reduce manufacturing difficulty, simplify the production process, and improve production efficiency. Of course, the mirror-symmetric design also makes it easier for the splicing segments 11 of different materials to evenly distribute the fragrance substances they carry, providing a more balanced and consistent fragrance release effect.

[0079] Of course, in other embodiments, functional segment 10 may also be an asymmetric structure, which is not limited here.

[0080] In some embodiments, functional segment 10 is a one-piece co-extruded structure.

[0081] Co-extrusion is a technique that involves simultaneously extruding two or more different materials through the same die. These materials can have different physical or chemical properties. In co-extrusion, each material enters the extruder through a separate feeding system, and then they are combined at the die and extruded together to form a single composite structure.

[0082] In this embodiment, the functional segment 10 is formed by co-extrusion molding, where each splicing segment 11 is joined together circumferentially. All splicing segments 11 are extruded simultaneously in a single operation, resulting in a tight bond between the splicing segments 11. This reduces unevenness caused by subsequent physical connections, decreases assembly steps, and increases the structural strength of the functional segment 10. Furthermore, it increases the design flexibility of the functional segment 10 without affecting overall performance. It also reduces overall production costs and waste rate.

[0083] In some embodiments, the outer contour of functional segment 10 has a columnar structure. This reduces manufacturing difficulty.

[0084] It should be noted that the columnar structure can be cylindrical, elliptical, or rectangular. For an example, please refer to [link to relevant documentation]. Figures 1 to 12 The outer contour of functional segment 10 is cylindrical.

[0085] In some embodiments, please refer to Figures 1 to 12The splicing segment 11 is provided with at least one through hole 11a, which penetrates the splicing segment 11 axially.

[0086] In this embodiment, the through-hole 11a facilitates airflow and adjusts the suction resistance of the aerosol-generated product, thus improving the user's suction experience. When the functional section 10 serves as a filter section and / or a pre-plug section, the size of the through-hole 11a can be smaller to screen the aerosol particle size.

[0087] The number of through holes 11a can be one or more. For example, the number of through holes 11a can be multiple, and the shape and size of the through holes 11a provided on a splicing segment 11 can be the same or different. For example, please refer to... Figure 7 and Figure 8 The shape and size of the through hole 11a are consistent.

[0088] For example, in some embodiments, please refer to Figures 1 to 6 , Figures 9 to 12 The number of through holes 11a is multiple, including a first through hole 11b and a second through hole 11c. The splicing segment 11 includes a first part and a second part that are connected to each other in the radial direction. The first through hole 11b is disposed in the first part, and the second through hole 11c is disposed in the second part. The size and / or shape of the first through hole 11b and the second through hole 11c are different.

[0089] The first through hole 11b and the second through hole 11c may have different sizes and / or shapes. For example, the first through hole 11b and the second through hole 11c may have different sizes but the same shape, such as both being circular, elliptical, triangular, or square holes. See the example provided. Figures 3 to 6 Both the first through hole 11b and the second through hole 11c are circular holes, with the diameter of the first through hole 11b being larger than that of the second through hole 11c. Alternatively, the first through hole 11b and the second through hole 11c can be the same size but different in shape; for example, the first through hole 11b can be circular, and the second through hole 11c can be square. Of course, the first through hole 11b and the second through hole 11c can also have different shapes and sizes. For example, please refer to [link to example]. Figure 1 and Figure 2 The first through hole 11b is a circular hole, and the second through hole 11c is a square hole, and the two are different sizes.

[0090] The number of the first through hole 11b and the second through hole 11c can be one or more, and there is no limitation here.

[0091] The first through hole 11b is provided in the first part, and the second through hole 11c is provided in the second part. In this way, the first through holes 11b of each splicing segment 11 can be roughly distributed in the same area, and the second through holes 11c of each splicing segment 11 can be roughly distributed in the same area, thereby increasing the uniformity of airflow and aroma release.

[0092] For example, the first through hole 11b is disposed radially along the functional segment 10 in the peripheral area of ​​the functional segment 10, that is, near the outer wall 111 of the splicing segment 11, and the second through hole 11c is disposed radially along the functional segment 10 in the inner peripheral area of ​​the functional segment 10, that is, away from the outer wall 111 of the splicing segment 11.

[0093] In some embodiments, the splicing segment 11 includes an inner wall 112 and an outer wall 111 disposed opposite each other in the radial direction, and the outer walls 111 of each splicing segment 11 are spliced ​​together to form the outer contour of the functional segment 10.

[0094] For example, the outer wall 111 of each splicing segment 11 can extend in an arc shape, and the outer contour of the functional segment 10 formed after splicing the outer walls 111 of each splicing segment 11 can be roughly cylindrical.

[0095] Please see Figures 5 to 8 , Figure 11 and Figure 12 The inner walls 112 of each splicing segment 11 are spaced apart to form a hollow channel 10a within the functional segment 10. That is, after the functional segment 10 is formed, the inner walls 112 of each splicing segment 11 are not joined together and gaps are formed, thereby defining the hollow channel 10a. In this way, the functional segment 10 can be roughly formed into a hollow tubular structure.

[0096] In this embodiment, the hollow channel 10a increases the aerosol flow area, thereby slowing down the aerosol flow rate and facilitating cooling of the aerosol, resulting in a more suitable operating temperature. It also reduces the overall weight of the functional section 10. In this embodiment, the functional section 10 serves as both a support section and / or a cooling section for the aerosol-generated product.

[0097] For example, please refer to Figures 5 to 8 , Figure 11 and Figure 12 In an embodiment where the functional segment 10 has a hollow channel 10a, the functional segment 10 may also be provided with the aforementioned through hole 11a. The functional segment 10 can serve as a support segment and / or a cooling segment. The hollow channel 10a and the through hole 11a together allow airflow to pass through, increasing the release area of ​​aerosols and aromas, while reducing suction resistance.

[0098] For example, in an embodiment where the functional segment 10 has a hollow channel 10a, the functional segment 10 is not provided with the aforementioned through hole 11a. The functional segment 10 can serve as a support segment and / or a cooling segment. The through hole 11a allows airflow to pass through, appropriately increasing the suction resistance and improving the user's suction experience.

[0099] In other embodiments, please refer to Figures 1 to 4 , Figure 9 and Figure 10 The inner walls 112 of each splicing segment 11 are spliced ​​together.

[0100] That is, after the functional segment 10 is formed, the inner walls 112 of each splicing segment 11 are joined together, and there are no gaps between the inner walls 112 of each splicing segment 11. The formed functional segment 10 is a solid structure.

[0101] In this embodiment, the inner walls 112 of each splicing segment 11 are spliced ​​together, which can increase the structural strength of the functional segment 10. At the same time, it is convenient to adjust the suction resistance of the aerosol generated product and improve the user's suction experience.

[0102] In the embodiment where the inner walls 112 of each splicing segment 11 are spliced ​​together, the functional segment 10 is provided with the above-mentioned through hole 11a. The through hole 11a allows airflow to pass through. At the same time, the particle size of aerosol can be filtered and screened by adjusting the airflow size, and condensate can be adsorbed. The functional segment 10 can serve as a filter segment and / or a pre-plug segment.

[0103] In some embodiments, there are two splicing segments 11. In the projection of the functional segment 10 along a plane perpendicular to the axis, the ratio of the projected areas of the two splicing segments 11 is 1 to 4, for example, 1, 1.2, 1.5, 2, 2.4, 2.5, 3, 3.3, 3.5, 3.6, 4.

[0104] In this embodiment, the ratio of the projected areas of the two splicing segments 11 is neither too large nor too small. On the one hand, this reduces the manufacturing difficulty, and on the other hand, it facilitates the uniform release of the fragrance substances loaded on different splicing segments 11.

[0105] For example, please refer to Figures 1 to 8 Let the projected area of ​​one of the splicing segments 11 be S1, and the projected area of ​​the other splicing segment 11 be S2, with a ratio of S1:S2 of 1:1. In this way, the content of fragrance substances contained in the two splicing segments 11 is nearly the same, and the fragrance release can be more uniform, increasing the user's smoking experience.

[0106] In other embodiments, please refer to Figures 9 to 12 The number of splicing segments 11 is at least three, and the projected area of ​​each splicing segment 11 is approximately the same in the plane projection of the functional segment 10 along the plane perpendicular to the axis.

[0107] For example, in an embodiment where the outer contour of functional segment 10 is cylindrical, the projected shape of splicing segment 11 is fan-shaped, and the central angles are consistent. For example, when there are three splicing segments 11, the central angle is 120°, and when there are four splicing segments 11, the central angle is 90°.

[0108] In this embodiment, the projected areas of each splicing segment 11 are approximately the same, which facilitates the loading of different fragrance substances, increases the uniformity of fragrance release, and enhances the aroma layering.

[0109] In some embodiments, the splice segments 11 are bonded together by non-covalent bonds.

[0110] Non-covalent bonds are weak interactions between molecules or materials that do not involve electron sharing.

[0111] The segments 11 are bonded together by non-covalent bonds, which avoids the problem of chemical incompatibility between different materials, reduces material degradation or performance changes caused by chemical reactions, and achieves multi-material compatibility. At the same time, the non-covalent bonding does not require complex chemical reactions or high temperature and high pressure conditions, making the manufacturing process of functional segment 10 simpler and less costly. In addition, the non-covalent bond setting also makes it easier to adjust the release rate of fragrance substances by means of temperature.

[0112] For example, when heated, the strength of the non-covalent bonds between the segments 11 may weaken, allowing aroma compounds to be released more easily from the segments 11. At low temperatures, the bonding between the segments 11 is more compact.

[0113] Non-covalent bonds include van der Waals forces, ionic bonds, hydrophobic bonds, hydrogen bonds, etc.

[0114] Van der Waals forces are weak forces formed by instantaneous dipole interactions or polarization attraction. They typically arise between nonpolar molecules.

[0115] Ionic bonds are formed by the electrostatic attraction between ions with opposite charges, and are typically formed between metal and nonmetal atoms or between positively and negatively charged organic molecules. For example, the bond between sodium ions and chloride ions, or between positively charged chitosan and negatively charged sodium carboxymethyl cellulose, is an ionic bond.

[0116] Hydrophobic bonds are interactions formed between hydrophobic molecules in aqueous solutions due to their aggregation.

[0117] A hydrogen bond is a bond force formed between a hydrogen atom and other strongly electronegative atoms (such as oxygen, nitrogen, or fluorine).

[0118] Therefore, in this embodiment, the material selection for each splicing segment 11 can be diversified. The materials of each splicing segment 11 can have differences in hydrophilicity and hydrophobicity, or they can all be hydrophobic polymers but with different charges, or they can all be hydrophilic polymers but with different charges.

[0119] For example, the splicing segment 11 can be made of a hydrophobic material, such as polylactic acid, ethyl cellulose, cellulose acetate, polyvinyl alcohol, and polyethylene glycol.

[0120] For example, the splicing segment 11 can be made of a hydrophilic polyhydroxy substance, such as cellulose, carboxymethyl cellulose, xanthan gum, chitosan, and hyaluronic acid.

[0121] For example, the splicing segment 11 can be a positively charged polymer, such as a substance with a positive charge imparted by an amino or quaternary ammonium salt structure. The splicing segment 11 can also be a negatively charged polymer, such as a substance with a negative charge imparted by a carboxyl group, phosphate group, sulfate group, etc.

[0122] The materials used in the splicing section 11 can be determined according to the type of fragrance substances it needs to carry, and no specific restrictions are made here.

[0123] The following is a brief description of the functional segment 10 of this application in conjunction with six embodiments. The structure of each splicing segment 11 is the same.

[0124] First embodiment:

[0125] Please see Figures 1 to 2 The functional segment 10 is cylindrical and includes two splicing segments 11. The inner walls 112 of the two splicing segments 11 are spliced ​​together. The ratio of the projected areas of the two splicing segments 11 is 1:1. Each splicing segment 11 is provided with multiple first through holes 11b and multiple second through holes 11c. The first through holes 11b are circular and the second through holes 11c are square.

[0126] Second embodiment:

[0127] Please see Figure 3 and Figure 4 Unlike the first embodiment, both the first through hole 11b and the second through hole 11c are circular, and the diameter of the first through hole 11b is larger than that of the second through hole 11c.

[0128] Third embodiment:

[0129] Please see Figure 5 and Figure 6 Unlike the second embodiment, the inner walls 112 of the two splicing segments 11 are spaced apart to form a hollow channel 10a within the functional segment 10.

[0130] Fourth embodiment:

[0131] Please see Figure 7 and Figure 8 Unlike the first embodiment, the inner walls 112 of the two splicing segments 11 are spaced apart to form a hollow channel 10a in the functional segment 10. The through holes 11a on each splicing segment 11 are the same in shape and size and are formed as triangular holes.

[0132] Fifth embodiment:

[0133] Please see Figure 9 and Figure 10 The functional segment 10 is cylindrical and includes three splicing segments 11. The inner walls 112 of the three splicing segments 11 are spliced ​​together. The ratio of the projected areas of the three splicing segments 11 is 1:1:1. Each splicing segment 11 is provided with multiple first through holes 11b and multiple second through holes 11c. Both the first through holes 11b and the second through holes 11c are circular. The diameter of the first through hole 11b is larger than that of the second through hole 11c.

[0134] Sixth embodiment:

[0135] Please see Figure 11 and Figure 12 The functional segment 10 is cylindrical and includes four splicing segments 11. The inner walls 112 of the four splicing segments 11 are spaced apart to form a hollow channel 10a within the functional segment 10. The ratio of the projected areas of the four splicing segments 11 is 1:1:1:1. Each splicing segment 11 is provided with multiple first through holes 11b and multiple second through holes 11c. Both the first through holes 11b and the second through holes 11c are circular, and the diameter of the first through hole 11b is larger than that of the second through hole 11c.

[0136] Please see Figures 13 to 17 This application also provides an aerosol generating article 100, including a matrix segment 20 and a functional segment 10 in any embodiment of this application.

[0137] The matrix segment 20 is used to generate aerosols, and the matrix segment 20 includes a distal lip end and a proximal lip end disposed opposite each other along the axial direction. The functional segment 10 is disposed at the proximal lip end and / or the distal lip end.

[0138] It should be noted that the aerosol generating article 100 adopts the functional segment 10 of any embodiment of this application, and the aerosol generating article 100 has all the advantages of the functional segment 10 of that embodiment, which will not be elaborated here.

[0139] For example, the matrix segment 20 has an air passage opening that extends axially through at least one end of the matrix segment. In this way, aerosols generated by the matrix segment 20 can be released directly from the air passage opening, and the aerosols have sufficient release space, thereby improving the utilization rate of the aerosols.

[0140] It is understandable that the matrix segment 20 having an airway opening that passes through at least one end of the matrix segment 20 along the axial direction includes a variety of cases.

[0141] The first type: the airway hole only passes through the matrix segment 20 and faces the distal lip end along the axis. In other words, the airway hole is formed as a blind hole, with one end open and the other end closed. Air from the external environment can enter the airway hole and carry away the aerosol generated by atomization.

[0142] The second type: the airway opening only passes through the end of the matrix segment 20 facing the lip end. In other words, the airway opening is formed as a blind opening, with one end open and the other end closed. Air from the external environment can carry aerosols and flow directly out of the matrix segment 20 through the airway opening.

[0143] The third type: the airway pores penetrate both ends of the matrix segment 20 along the axial direction. That is to say, the airway pores penetrate both the proximal and distal lip ends, and the airway pores are open at both ends. Air from the external environment enters the airway pores, carries away the aerosols, and flows out, resulting in high aerosol utilization.

[0144] There is no limit to the number of airway openings; there can be one, two, or more.

[0145] Understandably, micropores are formed in the matrix segment 20, and these micropores are interconnected to form micro-airways. Some of the micropores communicate with the airway pores, while other micro-airways directly pass through the proximal and distal lip ends of the matrix segment 20. This allows aerosols to be expelled from the matrix segment 20 in multiple ways. For example, aerosols generated after heating the matrix segment 20 can directly enter the airway pores and be entrained and expelled by air from the external environment; alternatively, air from the external environment can directly enter the micro-airways and expel the aerosols within them; or, the aerosols can enter the airway pores from the micro-airways.

[0146] It is understood that the interconnection between micropores can be partial or non-interconnected, or all micropores can be interconnected. For example, in an embodiment where the matrix segment 20 is a particle aggregate, the gaps between the particles constitute the micropores, wherein the size of the micropores is determined by the gaps between the particles of the matrix segment 20.

[0147] It should be noted that airway pores are pores in a macroscopic sense, which can be seen with the naked eye, while micropores are pores in a microscopic sense, which cannot be seen with the naked eye.

[0148] The air pores and micropores can increase the surface area of ​​the matrix section 20, facilitating heat transfer and improving heating efficiency. When the aerosol-generating matrix within the matrix section 20 is heated, it releases aerosols, which leave the matrix section 20 under the negative pressure generated by the user's suction. The air pores and micropores can reduce the suction resistance of the user's suction, improving the user experience and reducing the adverse effects of condensed aerosol residue in the matrix section 20 on airflow.

[0149] In some embodiments, the number of functional segments 10 may be one; for example, please refer to [link to relevant documentation]. Figure 13 Functional segment 10 is located near the lip end of matrix segment 20. In this embodiment, matrix segment 20 can generate aerosol by ignition. The user can hold functional segment 10 for suction. Functional segment 10 can serve as a filter segment.

[0150] For example, please refer to Figure 14 Functional segment 10 is located near the lip end of matrix segment 20. In this embodiment, matrix segment 20 can be used in conjunction with an aerosol generating device to generate aerosols by heating without combustion. Functional segment 10 can serve as a filter segment.

[0151] In some embodiments, there are multiple functional segments 10, with at least one functional segment 10 disposed near the lip end and at least one functional segment 10 disposed at the distal lip end.

[0152] Thus, the functional segment 10 of this application embodiment can be located both near the lip end and far the lip end.

[0153] For example, there are two functional segments 10, one functional segment 10 is located at the distal lip end and the other functional segment 10 is located at the proximal lip end. The functional segment 10 located at the distal lip end can serve as a pre-plug segment, and the functional segment 10 located at the proximal lip end can serve as any one of a filtering segment, a cooling segment, or a support segment.

[0154] In this embodiment, the aerosol-generated product 100 can be a three-segment combined structure, a four-segment combined structure, or a five-segment combined structure, etc., and there is no limitation here.

[0155] For example, please refer to Figure 15 The aerosol generating product 100 has a three-section combined structure. There are two functional sections 10. One functional section 10 is located at the distal lip end of the matrix section 20 as a pre-plug section, and the other functional section 10 is located at the proximal lip end of the matrix section 20 as a filter section.

[0156] Taking the functional segment 10 located near the lip end of the matrix segment 20 as a filter segment as an example, when the aerosol generating article 100 has a three-segment combined structure, there are no other segments between the functional segment 10 located near the lip end of the matrix segment 20 and the matrix segment; when the aerosol generating article 100 has a four-segment combined structure, a support segment or a cooling segment may be provided between the functional segment 10 located near the lip end of the matrix segment 20 and the matrix segment 20, and the structure of the support segment or cooling segment is different from the structure of the functional segment 10 in the embodiment of this application; when the aerosol generating article 100 has a five-segment combined structure, a support segment and a cooling segment may be provided between the functional segment 10 located near the lip end of the matrix segment 20 and the matrix segment, and the structure of the support segment and the cooling segment is different from the structure of the functional segment 10 in the embodiment of this application, and the positions of the support segment and the cooling segment relative to the matrix segment can be interchanged.

[0157] For example, there are three functional segments 10: one functional segment 10 is located at the distal lip end of the matrix segment 20, and two functional segments 10 are located at the proximal lip end of the matrix segment 20. The functional segment 10 located at the distal lip end can serve as a pre-plug segment, and the functional segment 10 located at the proximal lip end can serve as any two of the following: a filtering segment, a cooling segment, and a support segment.

[0158] In this embodiment, the aerosol-generated product 100 can be a four-segment or five-segment combination structure, etc., and there is no limitation.

[0159] For example, please refer to Figure 16 The aerosol generating product 100 has a four-segment combined structure. There are three functional segments 10. One functional segment 10 is located at the distal lip end of the matrix segment 20 as a front plug segment. The other two functional segments 10 are located at the proximal lip end of the matrix segment 20. Along the direction from the distal lip end of the matrix segment 20 to the proximal lip end of the matrix segment 20, they serve as a cooling segment (or support segment) and a filtering segment, respectively.

[0160] For example, there are four functional segments 10, one functional segment 10 is disposed at the distal lip end of the matrix segment 20, and three functional segments 10 are disposed at the proximal lip end of the matrix segment 20. The functional segment 10 disposed at the distal lip end can serve as a pre-plug segment, and the functional segments 10 disposed at the proximal lip end can serve as a filter segment, a cooling segment, and a support segment, respectively.

[0161] For example, please refer to Figure 17 The aerosol generating product 100 has a five-segment combined structure. There are four functional segments 10. One functional segment 10 is located at the distal lip end of the matrix segment 20 as the pre-plug segment. The other three functional segments 10 are located at the proximal lip end of the matrix segment 20. Along the direction from the distal lip end of the matrix segment 20 to the proximal lip end of the matrix segment 20, they serve as the support segment, cooling segment, and filtration segment in sequence.

[0162] In some embodiments, please refer to Figure 16 and Figure 17 The aerosol-generating article 100 includes an encapsulation layer 30, which encapsulates at least a portion of the structure of the matrix segment 20 and the functional segment 10.

[0163] The wrapping layer 30 wraps around the outer periphery of at least a portion of the structure of the matrix segment 20 and the functional segment 10, meaning that the wrapping layer 30 wraps around the outer periphery of the matrix segment 20 and at least a portion of the outer periphery of the functional segment 10, which is beneficial to the reliability of the connection between the matrix segment 20 and the functional segment 10.

[0164] The coating layer 30 has a certain degree of hardness, which can protect the matrix section 20 and reduce the surface area of ​​the matrix section 20 directly exposed to the outside world. This reduces the probability of the matrix section 20 becoming damp and deteriorating due to contact with air. At the same time, it helps to reduce the probability of the matrix section 20 coming into contact with other components of the aerosol generation device and causing pollution.

[0165] The material of the wrapping layer 30 is not limited, and may be one or more of the following materials: fiber paper, metal foil, metal foil composite fiber paper, polyethylene (PE), polyethylene composite fiber paper, PBAT (Poly(butylene adipate-co-terephthalate)).

[0166] It should be noted that when at least one functional segment 10 is located near the lip and the covering layer 30 covers the entire outer wall of the functional segment 10, the user can directly hold the covering layer 30 in their mouth to inhale the aerosol. When the covering layer 30 covers only part of the outer wall of the functional segment 10, the user can directly hold the part of the functional segment 10 exposed outside the covering layer 30 in their mouth to inhale the aerosol. Of course, the user can also attach a mouthpiece to the functional segment 10 and inhale the aerosol through the mouthpiece.

[0167] It should be noted that the encapsulation layer 30 can be a single layer, that is, a single encapsulation layer 30 can simultaneously encapsulate the matrix segment and the functional segment 10.

[0168] Of course, the encapsulation layer 30 can also be multi-layered. The matrix segment 20 and the functional segment 10 can each be encapsulated by at least one encapsulation layer 30, resulting in a multi-segment structure. The multi-segment structure is then encapsulated by one or more encapsulation layers 30 to obtain the aerosol-generated product 100. In this embodiment, when there are multiple functional segments 10, the multiple functional segments 10 can each be encapsulated by at least one encapsulation layer 30, or the functional segments 10 located near the lip end can be simultaneously encapsulated together by at least one encapsulation layer 30. There are no restrictions on this.

[0169] This application provides an aerosol generation system, including an aerosol generation device and an aerosol generation article 100 according to any embodiment of this application.

[0170] The aerosol generating device includes a heating component, and the matrix section 20 generates aerosols under the heating action of the heating component.

[0171] The way the aerosol generating article is matched with the aerosol generating device is not limited. For example, the aerosol generating article 100 is plugged into the aerosol generating device.

[0172] It should be noted that when the aerosol generation system adopts the aerosol generation article 100 of any embodiment of this application, the aerosol generation system has all the advantages of the aerosol generation article 100 of that embodiment, which will not be elaborated here.
