Description

Technical Field

[0001] The present application relates to the field of aerosol generation technology, and in particular to an aerosol generating product and an aerosol generating system. Background Art

[0002] Fragrances can be added to aerosol-generating products. After the fragrance evaporates, it mixes into the aerosol, which can enrich the fragrance of the aerosol. In the related art, fragrances are mostly in the form of essential oils. After the aerosol-generating product is opened, the fragrance is easy to volatilize. If the aerosol-generating product is used after a long time after opening the box, the fragrance may have completely evaporated or there is less left, resulting in the aerosol generated by the aerosol-generating product in the early stage of opening the box and the aerosol generated in the later stage of opening the box being inconsistent in taste. In addition, when the aerosol-generating product is heated to generate aerosol, since the fragrance in the form of essential oil evaporates quickly when heated, during the entire time period of aerosol generation, the fragrance content in the aerosol-generating product in the early stage is higher and the fragrance is stronger; while in the later stage, due to the volatilization of the fragrance, the fragrance content in the aerosol-generating product is lower, or even completely evaporated in the early stage, so the fragrance is lighter, resulting in poor taste consistency of the aerosol during the entire use process.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0036] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] This application provides an aerosol generating article. Figure 1The aerosol-generating article 100 may include a smoke-generating section 10, a flavor-carrying section 20, a cooling section 30, and a filter section 40. The aerosol-generating article 100 may be cylindrical, with a cross-section that may be circular, elliptical, or polygonal. The aerosol-generating article 100 has a lengthwise direction. It has a proximal lip end and a distal lip end that are oppositely disposed, wherein the proximal lip end is the end that is closer to the user's lips during use, and the distal lip end is the end that is farther from the user's lips during use. The smoke-generating section 10 is used to generate an aerosol when heated. The material of the smoke-generating section 10 may be granular, shredded tobacco, block, or reconstituted tobacco leaf, among others. The flavor-carrying section 20 and the smoke-generating section 10 are disposed at the distal lip end. The flavor-carrying section 20 generates aroma, which may be in the form of mist or aerosol. The aroma is mixed into the aerosol to enrich or improve the mouthfeel of the aerosol. The cooling section 30 and the filter section 40 are disposed at the proximal lip end. The cooling unit 30 can cool the aerosol flowing through the filter unit 40 so that the temperature is not too high. The filter unit 40 is used to filter the aerosol to reduce harmful substances in the aerosol.

[0038] See also Figure 1 The aroma carrier 20 is positioned adjacent to the smoke generating section 10. For example, the aroma carrier 20 and the smoke generating section 10 may be positioned adjacent to each other in the longitudinal direction; alternatively, the aroma carrier 20 and the smoke generating section 10 may be nested in the vertical direction, or other arrangements may be made such that the aroma carrier 20 is positioned adjacent to the smoke generating section 10. Generally, the smoke generating section 10 needs to be positioned adjacent to the heating element when in use. The heating element heats the smoke generating section 10 to generate aerosol. Since the heating element reaches a higher temperature during heating, the area adjacent to the smoke generating section 10 has a higher temperature. Furthermore, the temperature drop of the aerosol generated by the smoke generating section 10 is smaller in the area adjacent to the smoke generating section 10, which also maintains a higher temperature in the area adjacent to the smoke generating section 10. Placing the aroma carrier 20 adjacent to the smoke generating section 10 allows the flavoring substances to volatilize and release fragrance under the influence of the heat energy in the area adjacent to the smoke generating section 10. Compared to aroma release at room temperature, the aroma release rate of the flavoring substances 22 is more controllable and more stable.

[0039] See also Figure 2The aroma carrier 20 includes a flavoring agent 22 and a carrier 21. The flavoring agent 22 is in powder form and generates an aroma when heated. This aroma mixes with the aerosol, improving the aerosol's taste. For example, the aroma carrier 20 may generate aroma when heated by the aerosol flowing through it. Alternatively, the aroma carrier 20 may generate aroma when heated by the aerosol and an external auxiliary heating element. Illustratively, during use, the aerosol-generating article 100 is inserted into the receiving chamber of the aerosol-generating device. The aerosol-generating device includes a heating element disposed upstream of the receiving chamber. The heating element heats the airflow entering the receiving chamber. The airflow can heat the smoke-generating section 10 and the fragrance-carrying section 20 as it flows through the smoke-generating section 10 and the fragrance-carrying section 20, allowing the fragrance-carrying section 20 to generate aroma under the action of the thermal energy of the aerosol flowing through the fragrance-carrying section 20. Alternatively, the aerosol-generating device also includes an auxiliary heating element disposed around the fragrance-carrying section 20 and the smoke-generating section 10. The auxiliary heating element heats the fragrance-carrying section 20 and the smoke-generating section 10 from the surrounding sides, allowing the fragrance-carrying section 20 to generate aroma under the action of the thermal energy of the aerosol and the heating of the external auxiliary heating element. The carrier 21 is used to carry the flavoring substance 22, and the flavoring substance 22 is attached to the carrier 21. For example, the flavoring substance 22 may be adsorbed on the carrier 21 or dispersed and fixed on the carrier 21, so that the flavoring substance 22 is not easily lost during production or use.

[0040] In the aerosol generating product 100 provided in the present application, the flavoring substance 22 of the flavor-carrying portion 20 is in powder form, and the flavoring substance 22 is set to be solid, so that the flavoring substance 22 has better stability and is not easy to volatilize at room temperature. During the heating process, it evaporates more slowly than essential oil-like spices, thereby delaying the attenuation of the aerosol taste and improving the taste consistency of the aerosol; and the flavor-carrying portion 20 is arranged adjacent to the smoke-generating portion 10. Since the adjacent area of ​​the smoke-generating portion 10 has a sufficient temperature to make the flavoring substance evaporate and emit fragrance, the flavoring substance 22 can continuously and stably release fragrance under the action of heat energy, further improving the taste consistency of the aerosol.

[0041] In addition, the packaging of aerosol-generating products is mostly made of paper. Compared with essential oil-like fragrances, the flavoring substance 22 is set to a solid powder form, so that the flavoring substance 22 is not easy to soak the packaging, and the user will not get their hands dirty when using it, which can improve the user experience.

[0042] The smoke generating unit 10 and the fragrance carrying unit 20 can be assembled into the device separately, or can be connected as a whole by bonding or snapping, so as to facilitate use. Figure 1As shown, the aerosol-generating article 100 further includes a wrapping member 50, which is hollow and cylindrical and encases the smoke-generating portion 10 and the flavor-carrying portion 20. Encasing the smoke-generating portion 10 and the flavor-carrying portion 20 within the wrapping member 50 forms a single unit, facilitating convenient use. If the aerosol-generating article 100 includes a cooling portion 30 and a filter portion 40, the wrapping member 50 may further encase the cooling portion 30 and the filter portion 40.

[0043] The following describes some configuration methods of the carrier 21. In one embodiment, Figure 1 As shown, carrier 21 is a porous medium, and flavoring material 22 is dispersed and adsorbed within the pores of carrier 21. Carrier 21 can be roughly cylindrical or hollow in shape, facilitating wrapping of aroma carrier 20 by wrapping member 50. Flavoring material 22 is evenly dispersed within the pores of carrier 21, allowing aroma carrier 20 to continuously and stably release aroma in all directions. Carrier 21 is a porous medium, which has a strong adsorption effect on powdered flavoring material 22, enhancing the adsorption force between flavoring material 22 and carrier 21, making it less likely for flavoring material 22 to fall off during production or use.

[0044] In one embodiment, the carrier 21 includes one of cotton, fiber, activated carbon, silicon dioxide, or polymer resin. The porous medium of the above materials can generate a strong adsorption force for the flavoring substance 22, making the flavoring substance 22 less likely to fall off during production or use.

[0045] In one embodiment, if Figure 4-Figure 7 As shown, carrier 21 is a gel in the form of a film or sheet, with flavoring material 22 dispersed and fixed on the gel. The gel has a certain viscosity, allowing it to adhere and fix the flavoring material 22. Flavoring material 22 can be adhered and fixed to the surface of the gel or embedded within the gel, preventing it from falling off during production or use. Furthermore, the film or sheet-like gel possesses a certain degree of flexibility, allowing the aroma carrier 20 to be easily processed into a predetermined shape, such as a column or hollow tube.

[0046] In one embodiment, the gel is rolled into a stick, such as Figure 4-Figure 5 As shown; or the gel folds and gathers into a rod, as Figure 6-Figure 7 Processing the gel into a stick shape can facilitate the wrapping member 50 to wrap the fragrance carrying portion 20, thereby enhancing the adaptability of the fragrance carrying portion 20.

[0047] In one embodiment, if Figure 5 、 Figure 7As shown, there is a gap in the fragrance carrying portion 20, which runs through the fragrance carrying portion 20 along the direction of the airflow during use. The gap in the fragrance carrying portion 20 is provided so that the aerosol can flow in the gap, thereby increasing the contact area between the aerosol and the carrier 21, so as to carry the fragrance and then output it.

[0048] The following describes several configuration options for flavoring material 22. Flavoring material 22 can be a powdered flavoring made by grinding and mixing, such as a blend of multiple spices. Alternatively, flavoring material 22 can be a powdered flavoring made by absorbing a single flavor onto a solid adsorbent. All of these flavoring materials 22 are in a solid state, resulting in better stability and resistance to volatilization at room temperature, thereby improving the taste consistency of the aerosol.

[0049] In one embodiment, the flavoring substance 22 is a microcapsule essence. Configuring the flavoring substance 22 as a microcapsule essence allows the flavoring substance 22 to form a nested structure, making the flavoring substance 22 less volatile at room temperature, thereby improving the stability of the flavoring substance 22.

[0050] like Figure 3 As shown, in one embodiment, the microcapsule flavoring comprises a capsule wall 221 and a flavoring core 222 embedded within the capsule wall 221. The capsule wall 221 is a heat-sensitive material that decomposes under the action of heat, allowing the flavoring core 222 to generate aroma upon heating. Encapsulating the flavoring core 222 within the capsule wall 221 prevents the flavoring core 222 from volatilizing, thereby enhancing the stability of the flavoring substance 22.

[0051] In one embodiment, the capsule wall 221 has micropores, and the fragrance core material 222 embedded in the capsule wall 221 can be solid, liquid, or a solid-liquid mixture. The fragrance generated by the fragrance core material 222 under the action of heat energy can be released from the micropores to the outside of the capsule wall 221.

[0052] In one embodiment, the particle size of the microcapsule flavor is 1-1000 μm. If the particle size of the microcapsule flavor is less than 1 μm, the particle size of the microcapsule flavor is small, the amount of flavor core material 222 embedded in the capsule wall 221 is small, and the aroma generated by the flavor core material 222 after the capsule wall 221 decomposes is small, which does not improve the taste of the aerosol; if the particle size of the microcapsule flavor is greater than 1000 μm, the particle size of the microcapsule flavor is large, which will reduce the interaction force between the microcapsule flavor and the carrier 21, causing the microcapsule flavor to easily fall off during production or use. Exemplarily, the particle size of the microcapsule flavor is 1 μm, 100 μm, 200 μm, 300 μm, 400 μm, 500 μm, 600 μm, 700 μm, 800 μm, 900 μm or 1000 μm, which is not specifically limited here.

[0053] In one embodiment, the capsule wall 221 comprises one of a chitosan capsule wall, a fruit capsule wall, a lecithin capsule wall, or a cyclodextrin capsule wall. Each of these capsule walls 221 can effectively encapsulate the flavor core material 222, thereby ensuring greater stability of the flavoring substance 22. The flavor core material 222 can be in a liquid, solid, or solid-liquid mixed state. For example, the flavor core material 222 can be a water-soluble flavoring, which can be one or more of lychee extract, blueberry extract, green tea extract, tangerine peel extract, and Yunnan olive extract. After the capsule wall 221 decomposes, the flavor core material 222 can generate an aroma that is mixed into the aerosol, thereby improving the mouthfeel of the aerosol.

[0054] As previously mentioned, the aroma carrier 20 is disposed adjacent to the smoke-generating section 10, and is located in an adjacent area of ​​the smoke-generating section 10, so that the aroma carrier 20 is close to the smoke-generating section 10. In one embodiment, the aroma carrier 20 is located on the lower side or upper side of the smoke-generating section 10. Placing the aroma carrier 20 on the lower side or upper side of the smoke-generating section 10 allows the aroma carrier 20 and the smoke-generating section 10 to be adjacent in the longitudinal direction, thereby utilizing the higher temperature in the adjacent area of ​​the smoke-generating section 10 to continuously and stably release aroma. Furthermore, arranging the aroma carrier 20 at one end of the smoke-generating section 10 allows the aroma carrier 20 and the smoke-generating section 10 to extend in the same direction, forming a rod-like structure with the smoke-generating section 10, which facilitates the wrapping of the aroma carrier 20 and the smoke-generating section 10 by the wrapping member 50.

[0055] In one embodiment, the aerosol-generating article 100 further includes a barrier 60, which blocks the end of the fragrance-carrying portion 20 away from the proximal lip end. The barrier 60 may be a sealing paper. If microcapsule fragrance drops from the fragrance-carrying portion 20, the sealing paper confines the microcapsule fragrance within the fragrance-carrying portion 20, thereby preventing the fragrance-carrying portion 20 from falling. It will be appreciated that the barrier 60 is breathable, allowing aerosol to pass through. When the carrier 21 is a gel, the flavoring material 22 is dispersed and fixed on the gel. The barrier 223 may be a mesh or porous structure, supporting and preventing the carrier 21 from falling.

[0056] This application provides a method for preparing an aerosol-generating product. Figure 8 , the preparation method 300 may include steps S310-S320:

[0057] S310. A flavoring substance 22 is attached to a carrier 21 to form a fragrance carrier 20, wherein the flavoring substance 22 is in powder form. Attaching the flavoring substance 22 to the carrier 21 prevents the flavoring substance 22 from falling off during production or use. The flavoring substance 22 can generate an aroma under the action of thermal energy, and the aroma mixes with the aerosol to improve the taste of the aerosol. For example, the fragrance carrier 20 can generate an aroma under the action of thermal energy from the aerosol flowing through the fragrance carrier 20; in another example, the fragrance carrier 20 can generate an aroma under the action of heating from an external auxiliary heating element. The flavoring substance 22 in the fragrance carrier 20 is in powder form. Setting the flavoring substance 22 in a solid state provides greater stability, making it less volatile at room temperature. During heating, the flavoring substance 22 evaporates more slowly than essential oil-like fragrances, thereby slowing the decay of the aerosol's taste and improving the consistency of the aerosol's taste.

[0058] S320: Provide a smoke generating unit 10 and place a flavor carrier 20 adjacent to the smoke generating unit 10 to produce an aerosol generating product 100. The flavor carrier 20 is positioned adjacent to the smoke generating unit 10. Because the area adjacent to the smoke generating unit 10 has a sufficient temperature to volatilize the flavoring material, the flavoring material 22 can be continuously and stably released under the action of thermal energy, further improving the taste consistency of the aerosol.

[0059] The following describes some methods for preparing the aroma carrier 20. In one embodiment, attaching the flavoring material 22 to the carrier 21 to form the aroma carrier 20 includes using a porous medium as the carrier 21 and spraying the flavoring material 22 onto the carrier 21 so that the flavoring material 22 is dispersed and adsorbed within the pores of the carrier 21. Spraying the flavoring material 22 onto the carrier 21 allows the flavoring material 22 to be more evenly dispersed within the pores of the carrier 21.

[0060] See also Figure 9 In one embodiment, attaching the flavoring substance 22 to the carrier 21 to form the aroma carrying portion 20 includes steps S311-S312:

[0061] S311, using gel as carrier 21, adds flavoring material 22 to the gel and stirs to disperse the flavoring material 22 in the gel. Stirring allows the flavoring material 22 to be more evenly dispersed in the gel, and the gel can adhere and fix the flavoring material 22, thereby preventing the flavoring material 22 from falling off during production or use.

[0062] S312: The gel containing the flavoring substance 22 is formed into a film or sheet and solidified. The gel can be applied to the film or sheet or formed into the film or sheet using a mold. Forming the carrier 21 into a film or sheet facilitates subsequent spatial processing of the flavor carrier 20 into a predetermined shape, such as a columnar or hollow cylindrical shape.

[0063] See also Figure 10-12 In one embodiment, attaching the flavor material 22 to the carrier 21 to form the aroma carrying portion 20 further includes step S313:

[0064] S313: Roll the solidified gel into a rod shape, or fold and gather the solidified gel into a rod shape. Processing the gel into a rod shape can facilitate the wrapping member 50 to wrap the fragrance carrying portion 20, thereby enhancing the adaptability of the fragrance carrying portion 20.

[0065] In one embodiment, a gap is left within the fragrance carrier 20, extending through the fragrance carrier 20 in the direction of airflow during use. When the gel is processed into a stick shape, the gap is left within the fragrance carrier 20, allowing the aerosol to flow through the gap, thereby increasing the contact area between the aerosol and the carrier 21, facilitating the transport of the fragrance.

[0066] The following describes several methods for preparing flavoring material 22. Flavoring material 22 can be a powdered flavoring blend of multiple spices, for example, prepared by grinding and mixing multiple spices. Alternatively, flavoring material 22 can be a powdered flavoring blend of monomeric flavors, for example, by adsorbing monomeric flavors onto a solid adsorbent. Flavoring material 22 prepared by these methods is in a solid state, resulting in greater stability and resistance to volatility at room temperature, thereby improving the taste consistency of the aerosol.

[0067] In one embodiment, the flavoring substance 22 is a microcapsule essence. Configuring the flavoring substance 22 as a microcapsule essence allows the flavoring substance 22 to form a nested structure, making the flavoring substance 22 less volatile at room temperature, thereby improving the stability of the flavoring substance 22.

[0068] Preparation methods for microencapsulated flavors can include physical, chemical, or physicochemical methods. Physical methods utilize physical and mechanical principles to prepare microcapsules, and can include spray drying, air suspension, or inclusion complexation. Chemical methods primarily utilize small monomer molecules to undergo polymerization reactions to generate polymers or membrane materials, which then encapsulate the core material. These methods can include interfacial polymerization or in-situ polymerization. Physicochemical methods involve modifying conditions (such as temperature and pH) to cause dissolved membrane materials to precipitate from the solution and encapsulate the core material to form microencapsulated flavors. These methods can include coacervation, oil phase separation, drying bath, or melt-dispersion condensation.

[0069] See also Figure 13 In one embodiment, the microcapsule flavor is prepared by the inclusion complexation method in the physical method. The preparation method of the microcapsule flavor includes steps S3111-S3113:

[0070] S3111, adding capsule wall materials and water into a container, stirring and heating. In one embodiment, the capsule wall material is at least one of chitosan, pectin, gelatin or cyclodextrin.

[0071] S3112: Add a flavor core material to the container and stir the mixture for a predetermined period of time to ensure that the capsule wall material and the flavor core material are fully contacted and encapsulated. In one embodiment, the flavor core material is in a liquid, solid, or solid-liquid mixed state. By encapsulating the flavor core material in the capsule wall, the microencapsulated fragrance has a sustained release property, thereby extending the release time of the fragrance.

[0072] S3113, refrigerating and allowing the mixture to stand to obtain a precipitate, filtering, washing and drying the precipitate to obtain the flavor substance in the form of microcapsules.

[0073] A brief description of the preparation method for microencapsulated flavors using leaf alcohol as the core material and β-cyclodextrin as the wall material is provided. The container is cleaned and heated in a water bath set to 38°C. After heating, the container is placed in a water bath and heated. 10 parts β-cyclodextrin and 100 parts deionized water are added to the container. A stirring device is installed and set to 350 rpm. The β-cyclodextrin is stirred and heated. The molecular weight of β-cyclodextrin is 1134.984, and the molecular weight of leaf alcohol is 100.16. A molar ratio of leaf alcohol to β-cyclodextrin is set to 2:1. The appropriate amount of leaf alcohol is weighed and added to the stirred β-cyclodextrin. The mixture is placed in a pre-heated water bath at 38°C. The mechanical stirrer is set to 580 rpm and stirred for 3 hours to ensure full contact between the β-cyclodextrin and the leaf alcohol. Once the leaf alcohol is encapsulated in the β-cyclodextrin, the container is refrigerated for 24 hours to allow the mixture to separate into layers, yielding a white solid inclusion complex as the lower layer. The mixture was filtered using a suction filtration apparatus, washed three times with 90% ethanol, and dried in a freeze dryer to obtain a powdered microcapsule essence.

[0074] Infrared testing was performed on leaf alcohol, β-cyclodextrin and microencapsulated flavors. The test results are shown in Figure 14 As can be seen from the figure, in the infrared spectrum of leaf alcohol, there is a carbon-hydrogen vibration peak between 500-1000cm-1 in the fingerprint area, a hydroxyl stretching vibration peak at about 3000cm-1, and a carbon-carbon double bond stretching vibration peak at 1500cm-1. Comparing the infrared spectrum curves of β-cyclodextrin, microencapsulated flavor, and leaf alcohol, it can be found that some vibration peaks of leaf alcohol disappear after embedding β-cyclodextrin. At the same time, the vibration intensity of other vibration peaks also changes. The vibration peaks of microencapsulated flavor and β-cyclodextrin are basically consistent. This shows that β-cyclodextrin has successfully embedded leaf alcohol.

[0075] Based on the above microcapsule flavor prepared with leaf alcohol and β-cyclodextrin, a flavor carrier was further prepared. The flavor carrier and blank β-cyclodextrin (i.e., β-cyclodextrin raw material without leaf alcohol) were subjected to thermogravimetric analysis. The thermogravimetric curve is shown as follows: Figure 15 As shown in the figure, the weight of the blank β-cyclodextrin begins to drop rapidly at 300°C, indicating that β-cyclodextrin undergoes substantial decomposition at 300°C. The thermogravimetric curve of the aroma carrier shows a gentle decrease between approximately 100°C and 280°C, while the thermogravimetric curve of the blank β-cyclodextrin is parallel to the temperature axis, indicating that the leaf alcohol in the aroma carrier is slowly released between 100°C and 280°C, and that the microencapsulated flavor in the aroma carrier has good stability. The figure further shows that after 280°C, the weight drops rapidly due to the release of fragrance from the substantial decomposition of the wall material. This allows the aroma carrier to generate a long-lasting, stable aroma under the action of thermal energy, improving the taste consistency of the aerosol.

[0076] In one embodiment, the aerosol generating product 100 is obtained by placing the fragrance carrier 20 in an adjacent area of ​​the smoke generating portion 10, including:

[0077] A barrier 60 is provided, sealing one end of the fragrance carrier 20. The barrier 60 may be a sealing paper. If the flavoring material 22 falls from the fragrance carrier 20, the sealing paper confines the flavoring material 22 within the fragrance carrier 20, thereby preventing the flavoring material 22 from falling. It is understood that the barrier 60 may be air-permeable, allowing aerosols to pass through. When the carrier 21 is a gel, the flavoring material 22 is dispersed and fixed on the gel. The barrier 223 may be a mesh or porous structure, supporting and preventing the carrier 21 from falling.

[0078] In one embodiment, the aerosol generating product 100 is obtained by placing the fragrance carrier 20 in an adjacent area of ​​the smoke generating portion 10, including:

[0079] A wrapping member 50 is provided, and the fragrance carrier 20 is placed on a side close to the smoke generating unit 10, and the wrapping member 50 is wrapped around the outer periphery of the fragrance carrier 20 and the smoke generating unit 10. Wrapping the fragrance carrier 20 and the smoke generating unit 10 in the wrapping member 50 forms the fragrance carrier 20 and the smoke generating unit 10 as a whole, which is convenient for use.

[0080] In one embodiment, the aerosol generating product 100 obtained by placing the fragrance carrying portion 20 in an adjacent area of ​​the smoke generating portion 10 further comprises:

[0081] The aroma carrier 20 is disposed on the downstream side of the smoke generating section 10, or on the upstream side of the smoke generating section 10. Placing the aroma carrier 20 on the downstream side or the upstream side of the smoke generating section 10 allows the aroma carrier 20 to be adjacent to the smoke generating section 10 in the longitudinal direction, allowing the higher temperature in the vicinity of the smoke generating section 10 to be utilized for continuous and stable aroma release. Furthermore, locating the aroma carrier 20 at one end of the smoke generating section 10 allows the aroma carrier 20 and the smoke generating section 10 to extend in the same direction, forming a rod-like structure with the smoke generating section 10, making it easier for the wrapping member 50 to wrap around the aroma carrier 20 and the smoke generating section 10.

[0082] In one embodiment, the aerosol generating product 100 obtained by placing the fragrance carrying portion 20 in an adjacent area of ​​the smoke generating portion 10 further comprises:

[0083] A filter unit 40 is provided and disposed downstream of the smoke generating unit 10 and the fragrance carrying unit 20. Disposing the filter unit 40 downstream of the smoke generating unit 10 and the fragrance carrying unit 20 allows the filter unit 40 to filter harmful substances from the aerosol as it flows through the filter unit 40, thereby reducing the harmful substances in the aerosol.

[0084] In one embodiment, the aerosol-generating article 100 further includes a cooling portion 30 and a filtering portion 40 . The smoke-generating portion 10 , the fragrance-carrying portion 20 , the cooling portion 30 , and the filtering portion 40 are placed in a hollow package 50 , thereby forming the aerosol-generating article 100 .

Figure 16 The aerosol generating system 400 includes an aerosol generating device 200 and the aerosol generating product 100 as described above. The aerosol generating device 200 is provided with a accommodating chamber 230, and the accommodating chamber 230 is used to insert the aerosol generating product 100. The aerosol generating device 200 includes a heating element 220 and an auxiliary heating element 210. The heating element 220 and the auxiliary heating element 210 can be resistance wires, and the heating element 220 and the auxiliary heating element 210 can generate heat when connected to a power source. The heating element 220 is arranged upstream of the accommodating chamber 230, and the heating element 220 is used to heat the airflow entering the accommodating chamber 230. When the user inhales, the heated airflow flows to the smoking portion 10 and the fragrance carrying portion 20, and the airflow can heat the smoking portion 10 and the fragrance carrying portion 20 when flowing through the smoking portion 10 and the fragrance carrying portion 20. The auxiliary heating element 210 is disposed around the fragrance carrier 20 and the smoke-generating section 10. The auxiliary heating element 210 is used to heat the fragrance carrier 20 and the smoke-generating section 10 from their surroundings. A heating element 220 is provided to generate a hot air flow to heat the fragrance carrier 20 and the smoke-generating section 10. Simultaneously, the auxiliary heating element 210 heats the fragrance carrier 20 and the smoke-generating section 10 from their surroundings. This increases the heating temperature of the fragrance carrier 20 and the smoke-generating section 10, ensuring stable aerosol generation from the smoke-generating section 10 and continuous aroma release from the fragrance carrier 20, thereby improving the taste consistency of the aerosol. The specific internal structure of the aerosol generating device 200 is not further described.
