[0041] In the description of the embodiments of the present application, it should be noted that the orientation or position relationship indicated by the term "first direction" or the like is based on the attached Figure 2 The orientation or positional relationship shown, these orientation terms are only for the convenience of describing the embodiments of 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 cannot be understood as a limitation on the embodiments of the present application.

[0042] The present application embodiment provides an aerosol generating product, please refer to Figures 1 to 5 , Figure 6 and Figure 7 , Fig. 9 The aerosol generating article comprises an aerosol generating substrate segment 10 and a functional segment 20.

[0043] The functional segment 20 is disposed at one end of the aerosol generating substrate segment 10 along the first direction, and the functional segment 20 at least includes a porous molecular sieve structure segment 21 having pores 21 a.

[0044] The aerosol generating product is used in conjunction with an aerosol generating device having a heating component. Specifically, the heating component heats and atomizes the aerosol generating substrate segment 10 in the aerosol generating product to generate an aerosol for users to inhale or for use in medicine, beauty, etc.

[0045] There are many heating methods for the heating component. Exemplarily, the heating methods include central heating and peripheral heating. The central heating method refers to the heating component being inserted into the interior of the aerosol generating product to bake and heat the aerosol generating product from the inside out. The peripheral heating method refers to the heating component being arranged at the periphery of the aerosol generating product to bake and heat the aerosol generating product from the outside in. These heating methods may specifically be resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc.

[0046] The specific structure of the aerosol generating matrix segment 10 is not limited here. For example, in one embodiment, the aerosol generating matrix segment 10 can be made of the atomizing medium itself, for example, made of the smoke flavoring medium. In other embodiments, the aerosol generating matrix segment 10 can also include a matrix and an atomizing medium disposed on the matrix. The matrix can be, for example, high temperature resistant carbon fiber. In this way, by providing the matrix, the strength of the aerosol generating matrix segment 10 can be improved, and it can also withstand a certain degree of high temperature without generating odor.

[0047] The specific components of the aerosol generating substrate segment 10 are not limited herein. For example, in one embodiment, the aerosol generating substrate segment 10 may include plant components, auxiliary components, smoke generating agent components, adhesive components, and the like.

[0048] In one embodiment, the plant component is one or more combinations of powders formed by crushing tobacco raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, and aromatic plants. The plant component is the core source of the flavor of the product. Endogenous substances in the plant component, such as nicotine, enter the human blood through atomization, promote the pituitary gland to produce dopamine, and thus obtain physiological satisfaction.

[0049] In one embodiment, 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 wall material after the plant component is formed, thereby improving the aerosol release rate.

[0050] 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 particles, reduce the friction between the particles, make the overall density of the particle distribution more uniform, and also reduce the pressure required for mold molding and reduce the wear of the mold.

[0051] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can slow down the loss of flavor substances during storage to a certain extent, increase the stability of flavor substances, and improve the sensory quality of products. Emulsifiers (also known as surfactants) can reduce the interfacial tension of water-soluble and water-insoluble components in the mixed system, and form a relatively strong film on the surface of the droplets or form a double electric layer on the surface of the droplets due to the charge given by the emulsifier, preventing the droplets from aggregating with each other and maintaining a uniform emulsion. Emulsifying and homogenizing two immiscible components can improve the consistency of product quality.

[0052] The function of the smoke-generating agent component is to generate a large amount of steam when heated, thereby increasing the amount of smoke of the smoking product. In one embodiment, the smoke-generating agent may include, for example: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butylene glycol and glycerol); an ester of a polyhydric alcohol (such as monoacetin, diacetin or triacetin); a monocarboxylic 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, diacetin mixture, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, lauryl acetate) or one or more combinations thereof.

[0053] In one embodiment, the adhesive component is a natural plant extract, a non-ionized modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive is in close contact with the interface of the product component material by wetting, generating an intermolecular attraction, thereby playing the role of bonding the powder, liquid, etc. of the component material. At the same time, the use of natural plant extracts and non-ionic adhesives can avoid the release of harmful substances such as methanol, formaldehyde, and acrolein caused by colloid modification, thereby improving the safety of the product.

[0054] Exemplarily, the aerosol generating matrix section 10 can be a particle combination, which is a reconstituted tobacco medium, for example, a reconstituted tobacco medium containing components such as smoke-generating agent and tobacco. The aerosol generating matrix section 10 is an integrated structure, for example, an integrated structure that can be formed by injection molding, compression molding or extrusion technology. Wherein extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the material is pushed forward by the screw through the action between the extruder barrel and the screw, and is continuously made into various cross-section products or semi-finished products through the die head. The aerosol matrix formed by extrusion molding is in strip shape.

[0055] Since the aerosol generating matrix segment 10 is a particle combination, it is an integrated medium when the aerosol generating matrix segment 10 is heated and sucked or stops being heated, and is not prone to disintegration and falling off. This solves the problems in the prior art of the thin sheet, filamentary or loose particle aerosol generating matrix segment 10, such as loose sheets, falling of filamentary components and particle components, and difficulty in cleaning.

[0056] In addition, the shape of the aerosol generating substrate segment 10 is not limited. For example, see Figure 2The aerosol generating matrix segment 10 can be columnar, and the cross-section of the columnar aerosol generating matrix segment 10 can be circular or in other shapes, such as polygonal (including but not limited to triangle, square, prism, etc.), elliptical, runway-shaped, etc., wherein the “special shape” refers to other symmetrical or asymmetrical shapes other than the shapes listed above.

[0057] The first direction is the arrangement direction of the aerosol generating matrix segment 10 and the functional segment 20. The aerosol generating product is inserted into the aerosol generating device along the first direction, and the aerosol generating product is also taken out of the aerosol generating device along the first direction. The length of the aerosol generating matrix segment 10 along the first direction can be longer, shorter, or the same as the length in other directions.

[0058] For example, when the aerosol generating substrate segment 10 has a cylindrical appearance, the first direction is the axial direction of the aerosol generating substrate segment 10. It should be noted that the axial length of the aerosol generating substrate segment 10 may be smaller than its diameter.

[0059] For another example, when the appearance of the aerosol generating matrix segment 10 is a rectangular parallelepiped, the first direction is still the direction defined above, that is, the arrangement direction of the aerosol generating matrix segment 10 and the functional segment 20, or the direction of taking and placing the aerosol generating product on the aerosol generating device. The first direction of the aerosol generating matrix segment 10 can be any direction of the length, width, and height of the rectangular parallelepiped.

[0060] For example, see Figure 2 The aerosol generating matrix segment 10 and the functional segment 20 may be cylinders with the same outer diameter and coaxially arranged, and the first direction is the axial direction of the aerosol generating matrix segment 10 and the functional segment 20 .

[0061] The functional segment 20 is disposed at one end of the aerosol generating substrate segment 10 along the first direction, and the aerosol released by the aerosol generating substrate segment 10 when heated flows toward the functional segment 20 .

[0062] It should be noted that the aerosol generating product generates aerosol by the aerosol generating substrate segment 10, and the functional segment 20 does not generate aerosol. It is understandable that if the functional segment 20 is heated, some gas may also be released, but it is not the aerosol that the user expects to inhale. The function of the functional segment 20 is to achieve the functions of cooling or filtering the aerosol generated when the aerosol generating substrate segment 10 is heated.

[0063] The functional section 20 can be divided into at least two sections, one of which is a porous molecular sieve structure section 21, for example, see Figures 3 to 5 The functional segment 20 may also be provided with a filtering segment 22 at one end of the porous molecular sieve structure segment 21 away from the aerosol generating matrix segment 10 .

[0064] Exemplarily, the filter segment 22 may adopt a fiber structure, for example, the filter segment 22 may be an acetate fiber structure.

[0065] The functional section 20 may also not be segmented, that is, the entire functional section 20 may be a porous molecular sieve structure section 21 .

[0066] See also Figure 1 and Figure 3 The aerosol generating product may further be provided with an outer wrapping layer 30 , which is coated on the outer peripheral side of the aerosol generating substrate segment 10 and the functional segment 20 .

[0067] The material of the outer wrapping layer 30 is not limited. For example, the outer wrapping layer 30 includes but is not limited to one or more combinations of fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE (polyethylene), PBAT (butylene adipate-co-terephthalate) and other materials.

[0068] Exemplarily, the outer wrapping layer 30 can be a one-layer or two-layer structure. For example, when the outer wrapping layer 30 is a one-layer structure, the aerosol generating matrix segment 10, the porous molecular sieve structure segment 21 and the filter segment 22 can be wrapped at the same time. When the outer wrapping layer 30 is a two-layer structure, the porous molecular sieve structure segment 21 and the filter segment 22 can be first wrapped by one outer wrapping layer 30, and then wrapped by another outer wrapping layer 30. Alternatively, the outer wrapping layer 30 can also be wrapped in other ways.

[0069] The material of the porous molecular sieve structure segment 21 is a porous molecular sieve, which is a porous crystal having a large number of naturally formed pores 21a. The pore sizes of the pores 21a are relatively uniform, and these pores 21a generally only allow molecules smaller than their pore sizes to enter. Therefore, the porous molecular sieve can be used to screen molecules in a substance by size.

[0070] Exemplarily, the pore size of the pore 21a in the porous molecular sieve structure segment 21 can be 50nm to 1000nm (including endpoint values). For example, the pore size of the pore 21a can be 50nm, 80nm, 120nm, 150nm, 300nm, 500nm, 800nm, 1000nm, etc.

[0071] Illustratively, the porosity of the porous molecular sieve structure segment 21 may be greater than or equal to 65%. For example, the porosity of the porous molecular sieve structure segment 21 may be 65%, 75%, 80%, 90%, 95%, etc.

[0072] For example, the specific surface area of ​​the porous molecular sieve structure segment 21 may be 19 m 2 / g~60m 2 / g (including endpoint values), for example, the specific surface area of ​​the porous molecular sieve structure segment 21 can be 19m 2 / g, 25m 2 / g, 35m 2 / g, 40m 2 / g, 50m 2 / g, 60m 2 / g, etc.

[0073] In the related art, the main reason why aerosol-generating products have a poor taste during the smoking process is that the aerosol particle size distribution is uneven, resulting in large particles remaining on the tongue surface, making the user feel residual and unclean. At the same time, the nicotine absorption rate is also low, so the user's physiological satisfaction is also low.

[0074] The aerosol generating product of the embodiment of the present application is provided with a porous molecular sieve structure segment 21 at one end of the aerosol generating matrix segment 10 along the first direction. When the aerosol passes through the pores 21a in the porous molecular sieve, its particle size can be homogenized and shaped, thereby reducing or even eliminating the residual and unclean feeling caused by the large particulate matter 21c remaining on the tongue surface. At the same time, the homogenized and shaped aerosol can improve the nicotine absorption rate, thereby also improving the physiological satisfaction of the user. In other words, by providing the porous molecular sieve structure segment 21, the user's smoking experience can be improved.

[0075] In addition, the temperature of the aerosol released by the aerosol generating matrix section 10 when heated is relatively high, and the porous molecular sieve structure section 21 can also cool the aerosol to avoid the situation of "burning the mouth" during the inhalation process.

[0076] In one embodiment, please refer to Figure 3 The porous molecular sieve structure segment 21 can be a natural plant colloid, such as konjac gum and other natural plant colloids.

[0077] In addition to being able to homogenize and shape the particle size of aerosols, natural plant colloids also have good moisturizing functions. Specifically, after the polyol smoke agent is atomized into microparticles, it expands in volume and absorbs moisture in the oral mucosa, causing the user to experience dry mouth and tongue. Natural plant colloids can not only increase the content of water molecules, but also have super hydrophilic ability. For example, one colloid molecule can include 10 to 20 water molecules. During the user's inhalation process, the aerosol released by the aerosol generating matrix segment 10 due to heat enters the pores 21a of the natural plant colloid for homogenization and shaping. At the same time, under the influence of the heat and flow of the aerosol, the water molecules included in the colloid molecules of the natural plant colloid can be taken out and pass through the filter segment 22 into the user's mouth together with the aerosol to replenish the water molecule content in the mouth and keep the mouth moist. Therefore, the dry mouth and tongue can be reduced, giving the user a better inhalation experience.

[0078] In addition, natural plant colloids can soften smoke and achieve biodegradability.

[0079] See also Figure 3 and Figure 4 At least two adjacent pores 21a in the natural plant colloid can be interconnected, that is, the two pores 21a can be directly connected, thereby increasing the contact area of ​​the aerosol in the flow of the pores 21a, so as to achieve a better cooling and rectifying effect.

[0080] In addition, the natural plant colloid also has micropores, which are holes with a pore size significantly smaller than that of the pores 21a. In some embodiments, at least two adjacent pores 21a may be connected through micropores, that is, two pores 21a may be connected through one or more micropores, thereby increasing the contact area of ​​the aerosol in the flow of the pores 21a, so as to achieve better cooling and rectification effects.

[0081] In one embodiment, please refer to Figure 5 and Figure 6 The porous molecular sieve structure segment 21 may also be a granular composition, in which at least part of the granular material 21c has pores 21a. In other words, the porous molecular sieve structure segment 21 may be composed of granular materials 21c, in which part of the granular materials 21c may have pores 21a, or all of the granular materials 21c may have pores 21a.

[0082] Illustratively, the particulate material 21c in the granular composition may be zeolite and diatomaceous earth.

[0083] A gap 21d is formed between two adjacent particulate materials 21c. During the user's inhalation process, a part of the aerosol released by the aerosol generating matrix segment 10 due to heat passes through the pores 21a for homogenization and shaping, and another part of the aerosol passes through the gap 21d, which can also be homogenized and shaped. In other words, the aerosol is filtered through the pores 21a on the particulate material 21c and the gap 21d between the particulate material 21c. After the aerosol passes through the pores 21a and the gap 21d respectively, it enters the user's mouth through the filter segment 22.

[0084] Exemplarily, the pitch of the gap 21d may be 10 μm to 50 μm (including end points), for example, the pitch of the gap 21d may be 10 μm, 20 μm, 30 μm, 40 μm, or 50 μm.

[0085] This size range can increase the flow path by 30% to 50%.

[0086] In addition, when the aerosol passes through the gap 21d, it flows along the side wall curved surface of the particulate matter 21c, and the temperature of the aerosol can be reduced from about 210°C to about 45°C, thereby better improving the cooling effect.

[0087] Furthermore, the particulate matter 21c in the granular composition may also be a flavor inclusion particle, that is, a flavor substance may be added to the granular composition, and the flavor substance may be adsorbed on the particulate matter 21c.

[0088] For example, the granular composition may be composited from a variety of materials such as flavoring substances, zeolite and diatomaceous earth.

[0089] Under the action of molecular gravity, a kind of "surface force" will be generated on the surface of the pore 21a. When the aerosol flows through the pore 21a, the aerosol particles collide with the surface of the pore 21a due to irregular movement. The hydroxyl groups (-OH) in the aerosol particles can produce molecular concentration on the surface of the pore 21a and combine with the polar aroma molecules in the aroma substance. Finally, the aerosol can carry the aroma substance out of the porous molecular sieve structure segment 21 to compensate for the smoke aroma and enhance the smoking taste.

[0090] In one embodiment, the porous molecular sieve structure segment 21 can be an integrally formed structure, for example, the porous molecular sieve structure segment 21 can be a thermoplastic formed structure, that is, the porous molecular sieve structure segment 21 can be formed into an integrally formed structure by thermoplastic forming. The porous molecular sieve structure segment 21 can also be a cast structure, that is, the porous molecular sieve structure segment 21 can also be formed into an integrally formed structure by casting.

[0091] For example, the natural plant colloid can be formed into an integrally formed structure by dissolving-thermoplastic molding-expanding into holes.

[0092] For example, the granular composition can be formed into an integrally formed structure by casting.

[0093] In addition, for the porous molecular sieve structure segment 21 using a granular composition, the porous molecular sieve structure segment 21 can also be a discrete granular structure. The discrete granular structure refers to a structure composed of separable granular substances 21c. The discrete granular structure is mainly combined together by wrapping and the like. After removing the wrapping, the granular substances 21c in the discrete granular structure can be separated from each other.

[0094] In one embodiment, please refer to Figures 6 to 11 At least a portion of the porous molecular sieve structure segment 21 may be spaced apart from the aerosol generating substrate segment 10 so that a cavity 10b is formed at the spaced apart location.

[0095] The cavity 10b has the function of aerosol accumulation and buffering, that is, during the user's inhalation process, part of the aerosol released by the aerosol generating matrix segment 10 due to heat can be temporarily stored in the cavity 10b to balance the flow rate, and the other part of the aerosol directly passes through the porous molecular sieve structure segment 21 and the filter segment 22 to enter the user's oral cavity. The aerosol temporarily stored in the cavity 10b gradually passes through the porous molecular sieve structure segment 21 and the filter segment 22 to enter the user's oral cavity during the subsequent inhalation process.

[0096] For example, see Figure 6 The porous molecular sieve structure segment 21 can be completely separated from the aerosol generating matrix segment 10, that is, the porous molecular sieve structure segment 21 is not in contact with the aerosol generating matrix segment 10, and a cavity 10b is formed between the two.

[0097] For example, the porous molecular sieve structure segment 21 may also be spaced apart from the aerosol generating matrix segment 10 in a partial region, for example, see Figures 7 to 11 The porous molecular sieve structure segment 21 can be provided with a first sub-segment 211 and a second sub-segment 212. The first sub-segment 211 is located between the aerosol generating matrix segment 10 and the second sub-segment 212. The outer dimensions of the first sub-segment 211 are smaller than those of the second sub-segment 212. A cavity 10b is formed on the outer peripheral side of the first sub-segment 211.

[0098] While forming the cavity 10b, the first sub-segment 211 and the second sub-segment 212 can also enable the porous molecular sieve structure segment 21 to have different cross-sectional sizes in the first sub-segment 211 and the second sub-segment 212, respectively. In other words, the first sub-segment 211 and the second sub-segment 212 form a step-by-step design, thereby increasing the filtration area of ​​the porous molecular sieve structure segment 21 as much as possible.

[0099] Also, see Figure 7 , Fig. 9 and Fig.11 A plurality of protrusions 211a protruding outwards may also be formed on the side wall of the first sub-segment 211. Figure 7 , Fig. 9 and Fig.11 The protrusion 211a in the embodiment extends along the first direction. In other embodiments, the protrusion 211a may also extend along other directions.

[0100] The raised portion 211a can increase the outer surface area of ​​the second sub-segment 212, thereby increasing the contact area between the aerosol in the cavity 10b and the outer surface of the second sub-segment 212, and further during the inhalation process, the aerosol in the cavity 10b can enter the second sub-segment 212 more quickly.

[0101] In one embodiment, please refer to Fig.10 One side of the molecular sieve structure segment along the first direction may be recessed toward the other opposite side to form a groove 21b.

[0102] Fig.10 The groove 21b is recessed from the side of the molecular sieve structure segment away from the aerosol generating matrix segment 10 toward the side close to the aerosol generating matrix segment 10. In another embodiment, the groove 21b may also be recessed from the side of the molecular sieve structure segment close to the aerosol generating matrix segment 10 toward the side away from the aerosol generating matrix segment 10.

[0103] In addition to having a similar accumulation and buffering function as the cavity 10b, the groove 21b can also prevent the aerosol from being repeatedly heated, thereby not only improving the aerosol extraction efficiency but also improving the smoking experience.

[0104] In one embodiment, please refer to Figures 3 to 6 , Figure 8 and Fig.10 The interior of the aerosol generating substrate segment 10 may further include at least one air channel 10a, and the air channel 10a runs through at least one of the two opposite ends of the aerosol generating substrate segment 10 along the first direction.

[0105] Figures 3 to 6 , Figure 8 and Fig.10 The air channel 10a passes through the opposite ends of the aerosol generating substrate segment 10 along the first direction. In some embodiments, the air channel 10a may also only pass through one end of the aerosol generating substrate segment 10 close to the functional segment 20, while the other end is a closed end. Alternatively, the air channel 10a may also only pass through one end of the aerosol generating substrate segment 10 away from the functional segment 20, while the other end is a closed end.

[0106] Compared with the air passage 10a penetrating one end of the aerosol generating substrate segment 10 along the first direction, the air passage 10a penetrating both ends of the aerosol generating substrate segment 10 along the first direction is more conducive to reducing the inhalation resistance of the user.

[0107] It should be noted that the air channel 10a is different from the pores 21a and micropores described in the embodiments of the present application. The air channel 10a is a hole in the macroscopic sense, while the pores 21a and micropores are both holes in the microscopic sense. The cross-sectional area and length of the air channel 10a are much larger than those of the pores 21a and micropores. The air channel 10a is mainly formed by processing, so the cross-sectional area and length of the air channel 10a can be changed according to the design requirements, while the cross-sectional area and length of the pores 21a and micropores are mainly formed naturally during the processing.

[0108] The number of the air passage 10a may be one or more.

[0109] The airway 10a may be as follows Figure 4 The straight airway 10a shown is an airway 10a extending along a straight line, or in other words, the extending direction of the straight airway 10a is a straight line.

[0110] The airway 10a may also be a spiral airway 10a. The spiral airway 10a is an airway 10a whose curvature is not zero in at least a part of the area along the extension direction. For example, along the extension direction of the spiral airway 10a, the spiral airway 10a may have a structure with both a curve segment with a curvature not zero and a straight line segment with a curvature of zero, or may have only a curve segment with a curvature not zero and no straight line segment with a curvature of zero. In other words, from the starting point to the end point of the spiral airway 10a along the extension direction, the spiral airway 10a does not need to extend in a straight line.

[0111] When there are multiple air passages 10 a , some of the air passages 10 a may be straight air passages 10 a , and other air passages 10 a may be spiral air passages 10 a .

[0112] The shape of the cross section of the airway 10a is not limited. For example, the cross section may be circular, polygonal (including but not limited to triangle, square, prism, etc.), elliptical, racetrack-shaped or irregular-shaped.

[0113] by Figure 3Taking the aerosol generating product shown as an example, when the aerosol generating matrix segment 10 is heated, the aerosol generating matrix segment 10 releases aerosol. Since at least some of the micropores or gaps in the wall material of the aerosol generating matrix segment 10 are connected to the airway 10a, the aerosol released by the aerosol generating matrix segment 10 when heated can enter the airway 10a through the micropores or gaps connected to the airway 10a. At the same time, external airflow such as air can enter the airway 10a of the aerosol generating matrix segment 10 from the end of the aerosol generating matrix segment 10 away from the functional segment 20. In this way, during the inhalation process, the airflow gathered in the airway 10a can carry the aerosol to the functional segment 20, and after being homogenized and shaped by the porous molecular sieve structure segment 21, it enters the user's mouth.

[0114] The airway 10a can extend the airflow path and increase the flow speed of the airflow in the aerosol generating matrix segment 10, thereby increasing the impact force of the airflow and allowing the aerosol to be evenly mixed, thereby improving the extraction efficiency and uniformity of the aerosol in the aerosol generating matrix segment 10 and enhancing the user's inhalation experience.
