Detailed description of the embodiments

[0046] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this 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 this application and should not be regarded as an improper restriction on this application.

[0047] In the embodiment of the present application, the “first direction” is based on the Figure 2 , Attachment Figure 4 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Figure 10 And attached Figure 12 It should be understood that these directional terms are only used to facilitate the description of this application and simplify the description, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting this application. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] like Figures 1 to 12 As shown, an embodiment of the present application provides an aerosol generating product on one hand, the aerosol generating product 100 includes a medium segment 10 and a functional segment 20, the medium segment 10 extends along a first direction and is used to generate an aerosol; the number of the functional segments 20 is one or more, one or more functional segments 20 and the medium segment 10 are arranged along the first direction, and at least one functional segment 20 is a special-shaped segment 21, and each special-shaped segment 21 includes at least two different functional units 211.

[0049] On the other hand, an embodiment of the present application provides an aerosol generating system, which includes an aerosol generating device and an aerosol generating article 100 according to any embodiment of the present application. The aerosol generating device includes a heating element, which is used to heat the medium segment 10 to generate an aerosol.

[0050] The heating element is used to convert electrical energy into thermal energy. The thermal energy acts on the medium segment 10. After being heated, the medium segment 10 can generate aerosol for users to use.

[0051] Specifically, the aerosol generating device includes a shell and a power supply assembly arranged in the shell. The shell has a storage chamber. The power output part of the power supply assembly is arranged in the storage chamber or around the side wall of the storage chamber. When the aerosol generating product 100 is inserted into the storage chamber at a position corresponding to the first direction range where the medium segment 10 is located, the power output part transmits power to the heating element in a contact or non-contact manner. The heating element receives energy from the outside and generates heat, thereby heating the medium segment 10 and generating an aerosol.

[0052] In the embodiments of the present application, the first direction does not specifically refer to the direction in which the outer contour of the media segment 10 is longest. Specifically, the direction in which the aerosol-generating article 100 is inserted into the storage chamber and the direction in which the aerosol-generating article 100 is removed from the storage chamber are both parallel to the first direction. The length of the media segment 10 along the first direction may be longer, shorter, or the same as the length in other directions.

[0053] For example, when the media segment 10 has a cylindrical profile, the first direction is the axial direction of the media segment 10. It should be noted that even when the axial length of the media segment 10 is less than its diameter, the first direction of the media segment 10 is still the axial direction. For another example, when the media segment 10 has a rectangular profile, the first direction is still the direction defined above, i.e., the direction for placing the aerosol-generating article 100 in and out of the receiving chamber. The first direction of the media segment 10 can be any of the length, width, or height of the rectangular parallelepiped.

[0054] In the embodiment of the present application, the dielectric segment 10 is generally cylindrical, which may be a cylindrical shape (i.e., a circular cross-section), a prismatic shape (i.e., a polygonal cross-section), an elliptical cylinder (i.e., an elliptical cross-section), etc., without limitation.

[0055] The two ends in the first direction are the proximal lip end and the distal lip end.

[0056] The lip-proximal end refers to the end of the aerosol-generating article 100 that is close to the user when the user uses the aerosol-generating article 100 , and the lip-distal end refers to the end of the aerosol-generating article 100 that is away from the user when the user uses the aerosol-generating article 100 .

[0057] In some embodiments, the media segment 10 can be a one-piece structure, that is, the media segment 10 is integrally formed. Exemplarily, the media segment 10 is a particle combination, also known as a powder combination, and is a reconstituted tobacco medium, such as a reconstituted tobacco medium containing a smoke-generating agent, tobacco, and other ingredients. The media segment 10 is a one-piece structure, for example, and can be formed into a one-piece structure through extrusion, injection molding, or die-casting processes. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the material is pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passes through the mold at the extruder outlet to form various cross-sectional products or semi-finished products. The media structure formed by extrusion molding is strip-shaped. In this way, the media segment 10 remains an integral medium even after being heated and pumped or after the heating stops, and is less likely to disintegrate and fall off. This solves the problems of thin-sheet, filamentous, or loose granular media segments 10 in the prior art, such as loose flakes, shedding of filamentous and granular components, difficulty in cleaning, and uneven composition.

[0058] In other embodiments, the medium section 10 may not adopt an integrally formed structure. For example, it may be in the form of disordered shredded tobacco (formed by directly shredding plant leaves), or ordered thin sheets (formed by the papermaking method using plant leaf materials and other materials), or granular (formed by the granulation method using plant leaf materials and other materials).

[0059] The number of the functional sections 20 is one or more, and at least one functional section 20 is a special-shaped section 21. That is to say, when the aerosol-generating article 100 includes only one functional section 20, the only functional section 20 of the aerosol-generating article 100 is the special-shaped section 21.

[0060] When the number of the functional sections 20 is multiple, some of the functional sections 20 may be special-shaped sections 21, or all of the functional sections 20 may be special-shaped sections 21. The multiple functional sections 20 can be divided into two parts, and the two parts are respectively located at both ends of the medium section 10 along the first direction; of course, all of the functional sections 20 may also be located at one end of the medium section 10 along the first direction.

[0061] Each special-shaped section 21 includes at least two different functional units 211, and different functional units 211 are used to perform different functions.

[0062] In the related art, no matter what kind of multi-structural design is adopted for the structure of the aerosol-generating article, its aerosol product can only be transported along the axial center of the aerosol-generating article, with a short transport stroke and a delivery trend that the transport speed and delivery amount are the highest at the axial center, which brings problems such as the stable delivery of the aerosol product and the control of temperature, etc. This prompts that the aerosol-generating article must consider problems such as filtration, pressure drop, and temperature reduction in the design, thus invisibly increasing the production cost of the aerosol-generating article.

[0063] In the aerosol-generating article of the embodiment of the present application, the aerosol-generating article 100 includes a medium section 10 and a functional section 20. The medium section 10 can generate aerosol when heated and atomized; the number of the functional sections 20 is one or more, at least one functional section 20 is a special-shaped section 21, and each special-shaped section 21 includes at least two different functional units 211, and different functional units 211 can perform different functions, that is, the special-shaped section 21 integrates multiple functions. In this way, the aerosol-generating article 100 can achieve the stable delivery of the aerosol and the reasonable control of the temperature by using fewer functional sections 20, thereby reducing the production cost of the aerosol-generating article 100.

[0064] As Figure 1 and Figure 2 shown, in some embodiments, both the medium section 10 and the functional section 20 are cylindrical structures and are coaxially arranged, and the first direction is the axial direction of both of them.

[0065] The special-shaped segment 21 is also a type of the functional segment 20 , and therefore, the special-shaped segment 21 is also a cylindrical structure.

[0066] The aerosol-generating article 100, formed by the cylindrical medium segment 10 and the functional segment 20, has a circular cross-section along the axial direction. When inserted into the receiving chamber of the aerosol-generating device, the aerosol-generating article 100 can be inserted into the receiving chamber without having to rotate the aerosol-generating article 100 axially to an angle that matches the receiving chamber. This facilitates user use and enhances the user experience.

[0067] At the same time, the medium segment 10 and the functional segments 20 are coaxially arranged, and the structure of the aerosol generating article 100 is also more compact.

[0068] It should be noted that the cross-sectional areas of the dielectric segment 10 and each functional segment 20 may be all equal, partially equal, partially unequal, or of course, all unequal. Figure 1 、 Figure 2 、 Figure 4 、 Figures 6 to 8 、 Figure 10 as well as Figure 12 In the illustrated aerosol-generating article 100 , the cross-sectional areas of the media segment 10 and the functional segments 20 are all equal.

[0069] In some embodiments, such as Figure 2 、 Figure 4 、 Figures 6 to 8 、 Figure 10 as well as Figure 12 As shown, the interior of the medium segment 10 has at least one airway hole 10a, and the airway hole 10a passes through at least one end of the medium segment 10 along the first direction.

[0070] The interior of the medium section 10 has at least one airway hole 10a, see Figure 2 、 Figure 4 、 Figures 6 to 8 、 Figure 10 as well as Figure 12 , the airway hole 10a passes through at least one end of the medium segment 10 along the first direction.

[0071] In this way, the aerosol generated by the heated atomization of the medium segment 10 can be released directly from the airway hole 10a, and the aerosol has sufficient release space, thereby improving the utilization rate of the aerosol.

[0072] It can be understood that micropores are formed in the medium section 10, and the micropores communicate with each other to form micro-air channels. Some of the micropores communicate with the airway holes 10a, and some of the micro-air channels directly pass through the air inlet end and the air outlet end of the medium section 10. In this way, the aerosol can be discharged from the medium section 10 in various ways. For example, the aerosol generated after the medium section 10 is heated can directly enter the airway holes 10a and be carried away by the air in the external environment; or, the air in the external environment directly enters the micro-air channels and carries away the aerosol in the micro-air channels; or, the aerosol enters the airway holes 10a from the micro-air channels.

[0073] It can be understood that the communication between the micropores can be that some of the micropores communicate and some do not; or all of the micropores communicate with each other. For example, in an embodiment where the medium section 10 is a particle aggregate, the gaps between the particles constitute the micropores, and the size of the micropores is determined by the gaps between the particles in the medium section 10.

[0074] It should be noted that the airway holes 10a are holes in the macroscopic sense and can be identified by the naked eye, while the micropores are holes in the microscopic sense and cannot be identified by the naked eye.

[0075] The airway holes 10a and the micropores can increase the surface area of the medium section 10, facilitate heat transfer, and improve the heating efficiency. The pore walls of the airway holes 10a constitute the inner surface of the medium section 10. The airway holes 10a can increase the inner surface area of the medium section 10, facilitate heat transfer, and improve the heating efficiency. In addition, the medium section 10 generates aerosol after heating, and the aerosol is collected in the airway holes 10a and is transported to the suction end under the action of the suction negative pressure. The airway holes 10a can reduce the suction resistance of the user's suction 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 section 10, the smaller the suction resistance experienced by the user, and the larger the flow resistance of the aerosol in the medium section 10, the larger the suction resistance experienced by the user.

[0076] It should be noted that the airway holes 10a are holes in the macroscopic sense and can be identified by the naked eye.

[0077] There is at least one airway hole 10a inside the medium section 10. It can be that there is one airway hole 10a inside the medium section 10, or there are multiple airway holes 10a inside the medium section 10.

[0078] It should be noted that the term "multiple" as used in the embodiments of the present application refers to a quantity of two or more.

[0079] Specifically, an example will be given below with multiple airway holes 10a.

[0080] In some embodiments, the airway holes 10a pass through the same end of the medium section 10 in the first direction, and the other ends are all closed.

[0081] In other embodiments, a part of the airway holes 10a pass through one end of the medium section 10 in the first direction, and another part of the airway holes 10a pass through the other end of the medium section 10 in the first direction.

[0082] In still other embodiments, please refer to Figure 2 , Figure 4 , Figures 6 to 8 , Figure 10 and Figure 12 , each airway hole 10a passes through both ends of the medium section 10 in the first direction, that is, the airway hole 10a extends along the first direction of the medium section 10, and the air flow can flow from one end of the medium section 10 to the other end through the airway hole 10a. Preferably, the airway hole 10a is parallel to the central axis of the medium section 10.

[0083] It should be noted that the shape of the airway hole 10a is not limited herein. Exemplarily, in a plane perpendicular to the first direction of the medium section 10, the cross-sectional shape of the airway hole 10a includes but is not limited to being circular, elliptical, racetrack-shaped or polygonal, where the polygon includes regular or irregular polygons.

[0084] Among them, the racetrack shape refers to: a shape similar to an athletics track, formed by alternately connecting two semi-circles with the same radius and two parallel straight sides.

[0085] Among them, the cross-sectional shape of the airway hole 10a refers to the cross-sectional shape of the airway hole 10a obtained by cutting along a plane perpendicular to the first direction of the medium section 10.

[0086] In addition, the cross-sectional shapes of the respective airway holes 10a may be exactly the same, or the cross-sectional shapes of at least two of the airway holes 10a may be different. For example, at least one of the airway holes 10a may have a circular cross-sectional shape, and at least one of the airway holes 10a may have a polygonal cross-sectional shape.

[0087] It should be noted that the specific composition of the medium section 10 is not limited herein. Exemplarily, in some embodiments, the medium section 10 may include plant components, auxiliary components, smoke agent components, adhesive components, fragrance components, etc.

[0088] 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, thereby improving the user experience. The auxiliary component can not only improve the fluidity of the mixed material, but also make the medium segment 10 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.

[0089] For example, the plant ingredients can be one or more combinations of powders formed from crushed tobacco leaves, tobacco leaf fragments, tobacco stems, tobacco dust, and flavorful plants. Plant ingredients are the core source of flavor, and endogenous substances in plant ingredients can produce a physiological sense of satisfaction in users. Endogenous substances, such as alkaloids, enter the human bloodstream and stimulate the pituitary gland to produce dopamine, thereby achieving a physiological sense of satisfaction.

[0090] Illustratively, the auxiliary ingredient may be one or more combinations of inorganic fillers, lubricants, and emulsifiers. Inorganic fillers include one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. Inorganic fillers can provide skeletal support for the plant ingredients and also have micropores, which can increase the porosity of the medium segment 10, thereby improving the aerosol release rate. Lubricants include one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase the fluidity of the plant ingredient powder, reduce friction between the plant ingredient powders, and achieve a more uniform overall density distribution. They can also reduce the pressure required during the extrusion molding process, reducing die wear. Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can, to a certain extent, slow the loss of flavoring substances during storage, increase the stability of flavoring substances, and enhance the sensory quality of the product.

[0091] 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, tributyrin); 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, tributyrin, lauryl acetate). One or more combinations thereof.

[0092] Illustratively, the binder component wets the interface of the component materials, creating close contact and intermolecular attraction, thereby bonding the component materials, such as powders and liquids. The binder component can be a natural plant extract, a non-ionically modified viscous polysaccharide, or a combination thereof, including tamarind polysaccharide, guar gum, and modified cellulose (e.g., carboxymethyl cellulose). The binder serves to bond the particles together, preventing them from loosening. Furthermore, it improves the water resistance of the media segment 10 and is harmless to the human body.

[0093] For example, flavoring ingredients are used to provide characteristic aromas, such as hay, roasted sweet, or solid or liquid substances containing nicotine. Flavoring ingredients can include one or more combinations of tobacco or other plant, aromatic plant extracts, extracts, essential oils, and absolutes. Flavoring ingredients can also include monomeric flavoring substances, such as one or more combinations of megastigmatrienone, neophytadiene, geraniol, and nerol.

[0094] In some embodiments, the aerosol generating product 100 further includes a wrapping layer, which wraps around the periphery of the medium segment 10 and the functional segment 20. The wrapping layer has a certain hardness and can provide a certain degree of protection for the medium segment 10 and the functional segment 20, thereby reducing the surface area of the medium segment 10 directly exposed to the outside world, thereby reducing the chance of the medium segment 10 becoming damp and deteriorating due to contact with the air. At the same time, it also reduces the chance of the medium segment 10 being contaminated by contact with other components in the aerosol generating device.

[0095] It should be noted that the medium section 10, the functional section 20, and the wrapping layer can be an integral structure. That is to say, the medium section 10, the functional section 20, and the wrapping layer are different parts of an integral structure. In this way, on the one hand, the relative positions of the medium section 10, the functional section 20, and the wrapping layer are fixed, which can reduce the probability of detachment of the medium section 10, the functional section 20, and the wrapping layer during the use of the aerosol generating article 100 due to factors such as temperature change and vibration; on the other hand, the medium section 10, the functional section 20, and the wrapping layer can be prepared synchronously, thereby reducing the manufacturing steps and improving the production efficiency.

[0096] For example, the integral structure of the medium part, the functional section 20, and the wrapping layer is formed by a co-extrusion process.

[0097] Of course, the medium section 10, the functional section 20, and the wrapping layer can also be a split structure.

[0098] The specific material of the wrapping layer is not limited. For example, it can be one or a combination of materials such as fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, PBAT (Poly(butylene adipate-co-terephthalate)), etc.

[0099] In some embodiments, as Figure 1 、 Figure 3 、 Figure 5 、 Figure 9 and Figure 11 shown, different functional units 211 can have different shapes, and different functional units 211 adopt different shapes to perform different functions.

[0100] It should be noted that in the embodiments of the present application, two functional units 211 with similar appearances but the same size should also be understood as two functional units 211 with different shapes. For example, Figure 9 and Figure 11 shown in the two special-shaped sections 21.

[0101] In other embodiments, as Figure 5 shown, different functional units 211 can also be made of different materials. Exemplarily, as Figure 5 shown in the special-shaped section 21, the special-shaped section 21 includes three functional units 211, and two of the functional units 211 have the same shape but use different materials, and can also achieve different functions.

[0102] In some embodiments, the functional unit 211 is at least one of the filtration unit 212, the phase change unit 213, the aroma enhancement unit 214, the adsorption unit 215, the cooling unit 216, and the support unit 217. Thus, one functional unit 211 can perform at least one function.

[0103] The filter unit 212 can filter harmful components from the aerosol and adjust the inhalation resistance.

[0104] The fragrance enhancing unit 214 has the effect of adding fragrance to the aerosol and providing sustained release.

[0105] The phase change unit 213 melts or partially vaporizes due to heat and overflows into the aerosol flow channel, which is beneficial to the extraction and transmission of the aerosol.

[0106] The adsorption unit 215 is used to adsorb condensed liquid generated by the aerosol.

[0107] The cooling unit 216 has a large specific surface area and can quickly reduce the temperature of the aerosol, thereby achieving temperature control of the aerosol.

[0108] The support unit 217 has supporting and temperature-resistant effects, ensuring that the aerosol generating article 100 maintains a stable shape during the inhalation process and ensuring the stability of aerosol delivery.

[0109] In some embodiments, the special-shaped segment 21 may be an integral structure. By adopting the special-shaped segment 21 with an integral structure, the special-shaped segment 21 can be manufactured synchronously, thereby reducing the manufacturing steps and improving production efficiency.

[0110] In some other embodiments, the special-shaped segment 21 may also be a modular structure, wherein each functional unit 211 of the modular special-shaped segment 21 is formed separately.

[0111] In some embodiments, the shaped segment 21 is a spliced, extruded, or injection-molded structure. In other words, the shaped segment 21 is an integrally molded structure, which provides a more stable overall structure. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, where the material is pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passes through a mold at the extruder outlet to form finished products or semi-finished products of various cross-sections.

[0112] In some embodiments, such as Figure 1 、 Figure 2 、 Figure 4 、 Figures 6 to 8 、 Figure 10 as well as Figure 12 As shown, the number of the functional segments 20 is greater than or equal to 1 and less than or equal to 4, and each functional segment 20 is one of the front plug segment 22 , the support segment 23 , the cooling segment, and the filtering segment 24 .

[0113] The front plug section 22 is located at the distal lip end of the aerosol-generating article 100 relative to the media section 10. When the aerosol-generating article 100 further includes a wrapper layer, the front plug section 22 can effectively reduce the probability of the media section 10 falling out of the wrapper layer, and can also adjust the draw resistance of the aerosol.

[0114] In addition, when the media section 10 has a porous structure, the front plug section 22 can effectively prevent the problem that after the aerosol condenses, it flows downward and remains in the receiving chamber of the aerosol-generating device, causing internal pollution of the receiving chamber and being difficult to clean, and the problem of flavor mixing that may occur when sucking aerosol-generating articles 100 of different flavors.

[0115] In some embodiments, as Figure 8 shown, the front plug section 22 has a through hole 22a that penetrates both ends of the front plug section 22 along the first direction. The heating element can pass through the through hole 22a to heat the media section 10 so that the media section 10 generates aerosol.

[0116] The heating element and the hole wall of the through hole 22a can be in contact or not in contact. For example, for heating elements using resistance, electromagnetic, or light wave heating, the heating element itself has a large amount of heat, and adhesives will be generated after heating the media section 10. The hole wall of the through hole 22a is in contact with the heating element, and the front plug section 22 can scrape the heating element. For heating elements using microwave needle center heating, the heating element itself does not generate heat but is heated by the heat of the media section 10. Therefore, the heat of the heating element is small, and the possibility of bonding with the heat generated by the media section 10 is small. The hole wall of the through hole 22a can be not in contact with the cleaning section.

[0117] It should be noted that the material of the front plug section 22 is not limited. Exemplarily, in some embodiments, the material of the front plug section 22 includes at least one of CA (Cellulose acetate), PET (Polyethylene glycol terephthalate), PLA (Polylactic acid), PC (Polycarbonate), and PA (polyamide fiber or nylon).

[0118] It can be understood that the front plug section 22 can be made of any of the above materials, or a mixture of several of the above materials, and this application does not limit this here.

[0119] Of course, the material of the front plug section 22 is not limited to only the several materials mentioned above. For example, it can also be silicone, plant materials, etc., which can be selected according to the actual situation.

[0120] The support section 23 can perform the function of the support unit 217 in the above embodiment, and supports the aerosol-generating article 100 to ensure the stability of the aerosol-generating article 100 during use.

[0121] The structure of the support section 23 is not limited. For example, it can be a hollow paper tube structure or a hollow aluminum foil tube structure. Hollow paper tube structures and hollow aluminum foil tube structures have excellent heat resistance, are not easily deformed by heat, and can maintain their shape after heat conduction, thereby improving the structural stability of the aerosol generating article 100.

[0122] Of course, it can also be a hollow acetate fiber structure, a hollow aluminum foil paper tube structure, a hollow silicone structure, etc.

[0123] The cooling section can perform the function of the cooling unit 216 in the above embodiment, which can quickly reduce the temperature of the aerosol to avoid the problem of the aerosol being "hot in the mouth".

[0124] The cooling section can be, for example, a hollow paper tube, an acetate tube, or an aluminum foil tube. Specifically, the cooling section has a porous interior. When the airflow, carrying the aerosol, passes through the cooling section, a Venturi effect is created (the Venturi effect refers to the phenomenon in which a fluid increases in velocity as it passes through a reduced flow area, with the velocity being inversely proportional to the flow area). This allows the aerosol to pass through the cooling section more quickly, allowing for faster extraction. The cooling section has a large specific surface area, enabling rapid cooling of the aerosol.

[0125] Of course, the cooling section can also be one of a hollow paper tube, a hollow acetate fiber or a corrugated paper tube.

[0126] The filter segment 24 can perform the function of the filter unit 212 in the above embodiment, filtering harmful substances in the aerosol and adjusting the inhalation resistance.

[0127] The filter section 24 may be a hollow acetate fiber structure or a solid acetate fiber structure, etc.

[0128] It should be noted that when the aerosol generating product 100 includes a wrapping layer, and the wrapping layer wraps the entire circumferential outer surface of the filter segment 24, the user can directly hold the wrapping layer in the mouth to use the aerosol. When the wrapping layer wraps part of the circumferential outer surface of the filter segment 24, the user can directly hold the filter segment 24 exposed outside the wrapping layer in the mouth to inhale the aerosol. Of course, the user can also install a suction nozzle on the outer surface of the filter segment 24 and inhale the aerosol through the suction nozzle.

[0129] In some embodiments, such as Figure 1 、 Figure 3 and Figure 5As shown, each functional unit 211 of each shaped section 21 is spliced one by one along the circumferential direction of the shaped section 21. For part of the aerosol flowing along the axial center of the aerosol generating article 100, each functional unit 211 can perform its respective function synchronously, and can reasonably control the temperature of the aerosol at the axial center of the aerosol generating article 100, as well as regulate the delivery amount and delivery rate. In this way, the aerosol can be delivered more smoothly along the axis of the aerosol generating article 100.

[0130] In some embodiments, such as Figure 1 and Figure 2 As shown, the number of functional units 211 of each shaped section 21 is two. The two functional units 211 are respectively a hollow structure and a solid structure, and the functional unit 211 with the solid structure is a filtering unit 212.

[0131] In the circumferential direction of the shaped section 21, the two functional units 211 can have equal volumes or unequal volumes.

[0132] The functional unit 211 with the solid structure constitutes the filtering unit 212, so that harmful components of the aerosol can be filtered and the draw resistance can be adjusted.

[0133] The functional unit 211 with the hollow structure is beneficial to the orderly transfer of the aerosol, reduces the entrapment effect of the aerosol, and improves the overall release efficiency of the aerosol.

[0134] In some embodiments, such as Figure 3 As shown, the two functional units 211 are respectively a hollow structure and a corrugated structure, and the functional unit 211 with the corrugated structure is a cooling unit 216.

[0135] The corrugated structure specifically has an inner wall and an outer wall. The inner wall encloses a hollow space. There are grooves between the inner wall and the outer wall, and the cross-section of the region between the inner wall and the outer wall is generally wavy.

[0136] The cooling unit 216 formed by the functional unit 211 with the corrugated structure, because of the groove structure arranged therein, increases the flow path of the aerosol, and can achieve a cooling effect of the aerosol from 45 to 150 °C.

[0137] In some embodiments, the functional unit 211 with the corrugated structure can also carry liquid or solid fragrances, etc., that is, the functional unit 211 with the corrugated structure can also achieve fragrance enhancement of the aerosol, etc.

[0138] The functional unit 211 with the hollow structure is beneficial to the orderly transfer of the aerosol, reduces the entrapment effect of the aerosol, and improves the overall release efficiency of the aerosol.

[0139] In some embodiments, the functional unit 211 with the solid structure is a solid acetate fiber structure formed by arranging tow in parallel and bundling them.

[0140] Specifically, the solid cellulose acetate structure generally forms a semi-cylindrical shape. In this way, when the aerosol flows through the functional unit 211 composed of the solid cellulose acetate structure, on the one hand, it can filter harmful substances in the aerosol; on the other hand, it can increase the suction resistance and reduce the probability of the "emptying" phenomenon occurring when inhaling the aerosol.

[0141] Cellulose acetate is a very easily obtainable artificial fiber with low cost. In this way, the production cost of the aerosol generating article 100 is further reduced. At the same time, cellulose acetate has good weaving properties, which also facilitates the processing of the functional unit 211.

[0142] In some embodiments, the functional unit 211 with a hollow structure is a hollow tubular structure or a hollow cellulose acetate structure.

[0143] The functional unit 211 with a hollow structure can reduce the overall weight of the aerosol generating article 100, and can utilize its hollow area to enable the aerosol to be transmitted orderly, and reduce the entrapment effect of the aerosol, thereby improving the aerosol release efficiency of the aerosol generating article 100.

[0144] The functional unit 211 with a hollow cellulose acetate structure can also reduce the production cost of the aerosol generating article 100 and is also convenient for processing.

[0145] In some embodiments, as Figure 1 and Figure 2 shown, the number of the functional segments 20 is one, and the functional segment 20 is a special-shaped segment 21. The two functional units 211 of the special-shaped segment 21 are a hollow structure and a solid structure respectively, and the functional unit 211 with a solid structure is a filtering unit 212.

[0146] That is to say, the aerosol generating article 100 of this embodiment is a two-stage type, one of which is a medium segment 10, and the other is a functional segment 20 presented as a special-shaped segment 21.

[0147] The two functional units 211 of the special-shaped segment 21 are spliced one by one along the circumferential direction. The functional unit 211 with a solid structure is the filtering unit 212, which can specifically be a solid cellulose acetate structure, and can realize the filtration of harmful components and the suction resistance adjustment of the aerosol. The suction resistance adjustment brought by it is 100 - 450 Pa.

[0148] The functional unit 211 with a hollow structure can specifically be a hollow cellulose acetate structure, which is beneficial to the orderly transmission of the aerosol, and reduces the entrapment effect of the aerosol, thereby improving the aerosol release efficiency of the aerosol generating article 100.

[0149] In some embodiments, as Figure 3 and Figure 4As shown, the functional section 20 includes a filtering section 24 and a shaped section 21. The medium section 10, the shaped section 21, and the filtering section 24 are arranged in sequence along the first direction. The two functional units 211 of the shaped section 21 are a hollow structure and a corrugated structure respectively, and the functional unit 211 with the corrugated structure is the cooling unit 216.

[0150] That is to say, the aerosol generating article 100 of this embodiment is a three-section type, where one section is the medium section 10, and the other two sections are both functional sections 20. One of the functional sections 20 is presented as the shaped section 21, and the other functional section 20 is the filtering section 24.

[0151] Specifically, the end where the medium section 10 is located is equivalent to the distal lip end of the aerosol generating article 100, and the end where the filtering section 24 is located is equivalent to the proximal lip end of the aerosol generating article 100.

[0152] The two functional units 211 of the shaped section 21 are spliced one by one along the circumferential direction. The functional unit 211 with the corrugated structure is the cooling unit 216, which can specifically be a corrugated groove rod. It has the function of carrying liquid or solid fragrances, etc. With the groove structure of the corrugated groove rod, it can increase the aerosol flow path and achieve an aerosol cooling effect of 45 - 150 °C.

[0153] The functional unit 211 with the hollow structure can specifically be a hollow acetate fiber structure, which is beneficial to the orderly transmission of the aerosol, reduces the aerosol interception effect, and improves the aerosol release efficiency of the aerosol generating article 100.

[0154] After passing through the shaped section 21, the aerosol flows to the filtering section 24. The filtering section 24 can specifically be a solid acetate fiber structure with a characteristic of parallel arrangement of tow, which can filter harmful components of the aerosol and adjust the draw resistance. The draw resistance adjustment brought by it is 100 - 450 Pa.

[0155] In some embodiments, as Figure 5 shown, the number of functional units 211 of each shaped section 21 is three. The three functional units 211 are respectively a flavor enhancing unit 214, a cooling unit 216, and an adsorption unit 215. The interior of the adsorption unit 215 has at least one flow channel.

[0156] The three functional units 211 can be equally divided along the circumferential direction of the shaped section 21, that is, the volumes of the three functional units 211 are equal.

[0157] Of course, the three functional units 211 can also be combined in other forms to form the shaped section 21.

[0158] When the aerosol flows through the flow channel inside the adsorption unit 215, the condensate formed by condensation can be adsorbed by the adsorption unit 215. In this way, the problem of the condensate flowing back and remaining in the accommodation chamber inside the aerosol generating device, causing pollution of the accommodation chamber, is avoided.

[0159] Specifically, the adsorption unit 215 has a porous structure, and its material is not limited. For example, it can be a porous powder with an adsorption effect, such as calcium carbonate, microcrystalline cellulose, carbon powder, etc., which are formed by extrusion molding.

[0160] The flavor enhancing unit 214 can be a solid, porous and loose flavor material, which has the effects of flavor supplement and slow release.

[0161] The temperature reducing unit 216 is used to reduce the temperature of the aerosol. Its material can be porous silica gel, PET (Polyethyleneglycol terephthalate), etc.

[0162] In this embodiment, the special-shaped section 21 integrates the flavor enhancing unit 214, the adsorption unit 215 and the temperature reducing unit 216. The special-shaped section 21 has at least three functions, and the special-shaped section 21 has a higher integration degree, further simplifying the overall structure of the aerosol generating article 100 and reducing the production cost of the aerosol generating article 100.

[0163] Based on the special-shaped section 21 of this embodiment, the aerosol generating article 100 of three specific embodiments will be used as examples for illustration below.

[0164] The first type: As Figure 6 shown, the functional section 20 includes a special-shaped section 21 and a filtering section 24, and the medium section 10, the special-shaped section 21 and the filtering section 24 are arranged in sequence along the first direction.

[0165] Specifically, one end where the medium section 10 is located is the far lip end of the aerosol generating article 100, and one end where the filtering section 24 is located is the near lip end of the aerosol generating article 100.

[0166] In this embodiment, the aerosol-generating product 100 has a three-section structure. The medium section 10 is used to generate the aerosol, and the shaped section 21 has three functional units 211, namely a flavoring unit 214, an adsorption unit 215, and a cooling unit 216. The flavoring unit 214 has the effect of adding fragrance to the aerosol and providing a sustained release. The adsorption unit 215 can adsorb the condensate formed by the condensation of the aerosol. The cooling unit 216 is used to control the temperature of the aerosol. After passing through the shaped section 21, the aerosol flows to the filter section 24. The filter section 24 is a solid or hollow acetate fiber structure with a side-by-side arrangement of filaments. It can filter harmful components from the aerosol and adjust the flow rate and draw resistance of the aerosol. The draw resistance is adjusted between 100-450 Pa, achieving a desired user experience.

[0167] The second type: Figure 7 As shown, the functional segment 20 includes a special-shaped segment 21, a filtering segment 24 and a supporting segment 23. The medium segment 10, the supporting segment 23, the special-shaped segment 21 and the filtering segment 24 are arranged in sequence along a first direction.

[0168] Specifically, the end where the media segment 10 is located is the distal lip end of the aerosol-generating article 100 , and the end where the filter segment 24 is located is the proximal lip end of the aerosol-generating article 100 .

[0169] In this embodiment, the aerosol-generating article 100 has a four-section structure. The medium section 10 is used to generate the aerosol, which then passes through the support section 23, the shaped section 21, and the filter section 24 before being inhaled by the user. The support section 23 enhances the atomization effect of the aerosol-generating article 100 and provides good support. The shaped section 21 has three functional units 211: a flavoring unit 214, an adsorption unit 215, and a cooling unit 216. The flavoring unit 214 provides a sustained release of the aerosol. The adsorption unit 215 adsorbs condensate formed by the condensation of the aerosol. The cooling unit 216 controls the temperature of the aerosol. After passing through the special-shaped section 21, the aerosol flows to the filter section 24. The filter section 24 is a solid or hollow acetate fiber structure with the characteristic of side-by-side arrangement of filament bundles. It can filter harmful components of the aerosol and adjust the flow rate and suction resistance of the aerosol. The suction resistance is adjusted between 100-450 Pa, which meets the user's suction experience.

[0170] The third type: the functional segment 20 includes a front plug segment 22, a support segment 23, a special-shaped segment 21 and a filter segment 24. The front plug segment 22, the medium segment 10, the support segment 23, the special-shaped segment 21 and the filter segment 24 are arranged in sequence along the first direction.

[0171] Specifically, one end where the front plug section 22 is located is the far lip end of the aerosol generating article 100, and one end where the filter section 24 is located is the near lip end of the aerosol generating article 100.

[0172] In this embodiment, the aerosol generating article 100 has a five-section structure. The front plug section 22 is used to reduce the probability of the medium section 10 falling off and can absorb the condensate formed after aerosol condensation. The medium section 10 is used to generate aerosol, and the aerosol passes through the support section 23, the special-shaped section 21, and the filter section 24 in sequence for the user to inhale. The support section 23 can improve the atomization effect of the aerosol generating article 100 and play a good supporting role. The special-shaped section 21 has three functional units 211, and the three functional units 211 are respectively a flavor enhancing unit 214, an adsorption unit 215, and a temperature reducing unit 216. The flavor enhancing unit 214 has the effects of flavor supplementing and slow release for the aerosol. The adsorption unit 215 can adsorb the condensate formed by aerosol condensation. The temperature reducing unit 216 is used to control the temperature of the aerosol. After passing through the special-shaped section 21, the aerosol flows to the filter section 24. The filter section 24 is a solid or hollow cellulose acetate structure with the characteristic of parallel arrangement of tow, which can filter harmful components of the aerosol and adjust the flow rate and suction resistance of the aerosol. The suction resistance adjustment brought by it is 100 - 450 Pa, meeting the user's suction experience.

[0173] In some embodiments, the functional units 211 of each special-shaped section 21 are sleeved one by one along the inner and outer directions. Thus, based on the aerosol flowing in different regions of the cross-section of the special-shaped section 21, the functional units 211 of the special-shaped section 21 can be controlled in stages, making the overall taste of the aerosol more uniform.

[0174] Specifically, the special-shaped section 21 of two specific embodiments will be exemplified below.

[0175] First: As Figure 9 and Figure 10 shown, the number of functional units 211 of each special-shaped section 21 is two. The functional unit 211 located inside is the flavor enhancing unit 214, and the functional unit 211 located outside is the support unit 217.

[0176] Second: As Figure 11 and Figure 12 shown, the number of functional units 211 of each special-shaped section 21 is three. The three functional units 211 are respectively a flavor enhancing unit 214, a support unit 217, and a phase change unit 213. The phase change unit 213, the flavor enhancing unit 214, and the support unit 217 are sleeved in sequence from the inside to the outside along the radial direction of the special-shaped section 21.

[0177] Based on the special-shaped segments 21 of the above two embodiments, the functional segments 20 of the aerosol generating article 100 may include a special-shaped segment 21 and a filter segment 24, and the medium segment 10, the special-shaped segment 21 and the filter segment 24 are arranged in sequence along the first direction.

[0178] That is, the aerosol generating articles 100 all have a three-section structure, and the only difference between them is the functional section 20 .

[0179] The following briefly introduces seven specific embodiments of the aerosol generating article 100 with reference to the accompanying drawings.

[0180] First embodiment

[0181] like Figure 1 and Figure 2 As shown, the aerosol generating article 100 is a two-section structure, one section is a medium section 10 , and the other section is a functional section 20 in the form of a special-shaped section 21 .

[0182] The medium segment 10 is a porous structure. An airway hole 10a is provided inside the porous medium segment 10 along a first direction and passes through at least one end. The airway hole 10a extends in the length direction of the medium segment 10 and generates an aerosol for inhalation under the action of a specific heat source.

[0183] The shaped segment 21 includes two functional units 211, which are arranged circumferentially along the shaped segment 21 and formed by a splicing process. One functional unit 211 is a solid acetate fiber structure characterized by a side-by-side arrangement of filaments. This solid acetate fiber structure constitutes a filter unit 212, which can filter harmful components from the aerosol and adjust the draw resistance, which is adjusted to 100-450 Pa. The other functional unit 211 is a hollow acetate fiber structure, which facilitates the orderly transfer of aerosols, reduces aerosol entrapment, and improves the aerosol release efficiency of the aerosol generating article 100.

[0184] Second embodiment

[0185] like Figure 3 and Figure 4 As shown, the aerosol generating product 100 has a three-section structure, one section is a medium section 10, and the other two sections are functional sections 20, wherein one functional section 20 is a special-shaped section 21, and the other functional section 20 is a filter section 24. The medium section 10, the special-shaped section 21 and the filter section 24 are arranged along a first direction, the medium section 10 is located at the far lip end, and the filter section 24 is located at the near lip end.

[0186] The medium segment 10 is a porous structure. An airway hole 10a is provided inside the porous medium segment 10 along a first direction and passes through at least one end. The airway hole 10a extends in the length direction of the medium segment 10 and generates an aerosol for inhalation under the action of a specific heat source.

[0187] The special-shaped segment 21 includes two functional units 211, which are arranged along the circumference of the special-shaped segment 21 and formed by a splicing process. One of the functional units 211 is a corrugated structure formed by corrugated groove rods, which has the function of carrying liquid or solid fragrances, etc. Because it is provided with a groove structure, it can increase the flow path of the aerosol and can achieve a cooling effect of 45-150°C for the aerosol. The other functional unit 211 is a hollow acetate fiber structure, which is conducive to the orderly transmission of the aerosol, reduces the interception effect of the aerosol, and improves the aerosol release efficiency of the aerosol generating product 100.

[0188] The filter section 24 is a solid acetate fiber structure with the characteristic of side-by-side arrangement of filament bundles, which can achieve the filtration of harmful components in aerosol and the adjustment of suction resistance, and the suction resistance brought about by it is adjusted to 100-450Pa.

[0189] Third embodiment

[0190] like Figure 5 and Figure 6 As shown, in this embodiment, the structure of the aerosol generating product 100 is substantially the same as that of the second embodiment, with the main differences including: the special-shaped segment 21 includes three functional units 211, which are an adsorption unit 215, a fragrance enhancement unit 214 and a cooling unit 216.

[0191] The three functional units 211 are in a circularly equally divided structure, i.e. the adsorption unit 215, the flavoring unit 214 and the cooling unit 216 are equally divided into three parts along the circumference and spliced together, wherein the adsorption unit 215 is formed by extrusion of a porous powder with adsorption effect, such as calcium carbonate, microcrystalline cellulose, carbon powder, etc.; the flavoring unit 214 can be a solid loose porous flavor material, which has the effects of replenishing fragrance and sustained release; the cooling unit 216 can be made of porous silica gel, PET, etc. When the aerosol flows through, its temperature entering the filter section 24 is reduced. After passing through the special-shaped section 21, the flue gas temperature is 70-120°C.

[0192] Fourth embodiment

[0193] like Figure 5 and Figure 7 As shown, in this embodiment, the structure of the aerosol generating product 100 is substantially the same as that of the third embodiment, and the main differences include: the aerosol generating product 100 is a four-section structure, and the functional section 20 includes a support section 23 in addition to the filter section 24 and the special-shaped section 21, and the support section 23 is arranged between the medium section 10 and the special-shaped section 21.

[0194] The support section 23 is a hollow porous structure, and is composed of glycerin, propylene glycol, tangerine peel powder, and calcium carbonate in a mass ratio of 10:10:30:50.

[0195] Glycerin and propylene glycol generate smoke when heated to a smoke temperature of 180-280° C., thereby improving the smoke emission effect of the aerosol generating product 100 ; and tangerine peel powder serves as a characteristic fragrance, which can be carried along with the smoke to produce fragrance.

[0196] Calcium carbonate is not easy to collapse when heated, has a good supporting effect, and has a porous shape, which is conducive to aerosol transport.

[0197] Fifth embodiment

[0198] like Figure 5 and Figure 8 As shown, in this embodiment, the structure of the aerosol generating product 100 is substantially the same as that of the fourth embodiment, and the main differences include: the aerosol generating product 100 is a five-segment structure, and the functional segment 20 includes a front plug segment 22 in addition to the filter segment 24, the special-shaped segment 21, and the support segment 23. The front plug segment 22 is arranged at one end of the medium segment 10 away from the support segment 23 along the first direction.
