[0002] This application claims priority to Chinese Patent Application No. 2024115785569, filed on November 6, 2024, entitled “Aerosol Generating Article, Aerosol Generating System and Method for Manufacturing Smoke Section”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of aerosol generation technology, specifically relating to an aerosol generation product, an aerosol generation system, and a method for manufacturing a smoke-generating section. Background Technology

[0004] With increasing consumer health awareness, the tobacco industry is constantly responding to evolving consumer demands and accelerating the research and development and promotion of new tobacco products. Among these, heated non-combustible aerosol generation technology is widely regarded as a hope and direction for the sustainable development of the tobacco industry. In this technology, the aerosol-generating product is placed in an aerosol-generating device, where it is heated to produce aerosols. However, in these technologies, the amount of aerosol generated is often insufficient and unstable. Furthermore, limitations in processing intensity restrict the amount of smoke-generating agents and flavorings that can be added, leading to insufficient aroma and short-lasting fragrance. Summary of the Invention

[0007] In one embodiment, the channel extends through both ends of the smoke-generating section along the aerosol flow direction within the aerosol-generating article.

[0008] In one embodiment, a plurality of channels are provided throughout the smoke-generating matrix; at least one of the channels is not filled with aroma-generating filler, and / or the smoke-generating matrix is ​​a loose porous body.

[0009] In one embodiment, the fragrance filler includes a fragrance carrier portion and a first fragrance compounded to the fragrance carrier portion.

[0010] In one embodiment, the fragrance carrier includes one or more of activated carbon, diatomaceous earth, molecular sieve, and porous polymer, and / or the first fragrance includes one or more of furanone, menthol, and ethyl maltol.

[0011] In one embodiment, the aroma-generating filler accounts for 10-20% of the mass percentage of the smoke-generating section.

[0012] In one embodiment, the smoke-generating section is tubular, ellipsoidal, or spherical.

[0013] In one embodiment, the smoking matrix is ​​formed by mixing and pressing tobacco powder, a second flavoring agent, a smoking agent, a filler, and a binder, wherein the moisture content of the mixture of tobacco powder, flavoring agent, smoking agent, filler, and binder is not greater than 5%.

[0014] In one embodiment, the second fragrance and smoke-generating agent account for 30-50% of the mass percentage of the smoke-generating section.

[0015] In one embodiment, the filler includes at least one of anhydrous lactose and microcrystalline cellulose.

[0016] Secondly, embodiments of this application provide an aerosol generation system, including the aerosol generation article and aerosol generation device as described in any one of the first aspects above;

[0017] The aerosol-generating article is installed inside the receiving cavity of the aerosol generating device and is completely contained within the receiving cavity, and is heated by the aerosol generating device.

[0018] Thirdly, embodiments of this application provide a method for manufacturing a smoke-generating section, comprising:

[0019] Tobacco powder, second flavoring agent, smoke-generating agent, filler and binder are mixed to obtain smoke-generating matrix;

[0020] The smoke-generating matrix is ​​stamped into a smoke-generating matrix with channels;

[0021] Aromatic filler is filled into at least one of the channels to obtain a smoke-generating section.

[0022] In one embodiment, the stamping pressure during the stamping of the smoke-generating matrix is ​​10kN to 40kN.

[0023] In one embodiment, tobacco powder, tobacco flavoring substances, smoke-generating agents, fillers, and binders are mixed evenly, including:

[0024] Mix tobacco powder, tobacco flavoring substances, smoke-generating agents, fillers and binders in a mass ratio of (20-30):(10-20):(20-30):(10-20):(10-20).

[0025] In one embodiment, the particle size of the tobacco powder, filler, and binder is 30 mesh to 100 mesh, and the moisture content of the smoking matrix is ​​0 to 5%.

In other words, in this embodiment of the application, by providing a through-hole in the smoke-generating section of the aerosol-generating product and filling it with aroma filler, once the aerosol-generating product is placed in the receiving cavity of the aerosol-generating device, the through-hole can simultaneously communicate with the receiving cavity and the suction end of the aerosol-generating product. This allows the fragrance and aroma filler in the smoke-generating section and the aroma filler in the through-hole to be released slowly and evenly while maintaining the structural strength of the smoke-generating matrix. This results in a longer and more stable smoke and aroma output, thereby improving the smoking quality. Attached Figure Description

[0050] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] This application provides an aerosol generating article, which includes an integral smoke-generating section, as shown in Figures 1 to 14. The smoke-generating section 10 includes a smoke-generating substrate 11, which is the main body of the smoke-generating section 10. It can be heated by an aerosol generating device to form aerosol. The smoke-generating substrate 11 is provided with a channel 12 that penetrates at least one end face along the aerosol flow direction in the aerosol generating article. That is, the smoke-generating substrate 11 is provided with a channel 12, and at least one of the channels 12 is filled with an aroma-generating filler 13.

[0052] The aerosol generating product provided in this application embodiment can be placed in the receiving cavity of the aerosol generating device. The smoke generating section 10 can be placed in the receiving cavity, and then the smoke generating section 10 can be heated by hot airflow or circumferential heating through the receiving cavity to generate aerosol and achieve the smoke generating effect.

[0053] In this embodiment, the smoke-generating section 10 is solid, and the smoke-generating substrate 11, as the main body of the smoke-generating section 10, has a moisture content of 0-5%. It can directly generate a fragrant aerosol under heating conditions, avoiding the problem of a burnt smell in the aerosol caused by direct heating on the package in the circumferential heating method.

[0054] In this embodiment, the smoking matrix 11 is formed by pressing together a mixture of tobacco powder, a second flavoring agent, a smoking agent, a filler, and a binder. The moisture content of the mixture of tobacco powder, second flavoring agent, smoking agent, filler, and binder is no more than 5%, which effectively ensures the processing strength of the smoking matrix. The appropriate moisture content in the mixture also reduces the molding difficulty, ensures that the smoking section 10 has a certain degree of fluffiness and breathability, and also ensures a certain amount of smoke.

[0055] In some embodiments, the second fragrance and the smoke-generating agent account for 30-50% of the mass of the smoke-generating section, which can ensure the amount of smoke and the amount of aroma while ensuring the processing strength.

[0056] In addition, in some embodiments, by weight, the smoking matrix 11 includes 20-30 parts of tobacco powder, 10-20 parts of second flavoring agent, 20-30 parts of smoking agent, 10-20 parts of filler and 10-20 parts of binder, which can ensure the amount of smoke and flavor while ensuring the processing strength.

[0057] In addition, in some embodiments, the particle size of the tobacco powder, filler and binder is 30 mesh to 100 mesh, for example, a range of one or any two of 30 mesh, 40 mesh, 50 mesh, 80 mesh and 100 mesh.

[0058] In addition, in some embodiments, the second fragrance includes at least one of monomeric synthetic fragrance, natural fragrance raw material, fragrance base and fragrance essence.

[0059] In addition, in some embodiments, the smoke-generating agent includes at least one of propylene glycol and glycerin.

[0060] In some embodiments, the filler includes at least one of anhydrous lactose and microcrystalline cellulose. The weight and volume of the smoking section 10 are adjusted to a suitable amount, making the smoking matrix 11 easy to mold.

[0061] In addition, in some embodiments, the adhesive includes at least one of carboxymethyl cellulose and dextrin, which can bind the powder raw materials into a solid and increase stability, preventing oxidation or decomposition. Furthermore, the combined effect of the filler and the adhesive gives the smoke-generating section 10 a better moisture-proof effect.

[0062] In this embodiment, by providing a through-hole 12 in the smoke-generating section 10 of the aerosol-generating product, when the aerosol-generating product is placed in the receiving cavity of the aerosol-generating device, the through-hole 12 can simultaneously communicate with the receiving cavity and the suction end of the aerosol-generating product. This allows the fragrance and flavoring in the smoke-generating section 10 and the through-hole 12 to be released slowly and evenly while maintaining the structural strength of the smoke-generating matrix 11. This results in a sustained and stable amount of smoke and aroma, effectively solving the problem that the existing solid smoke-generating section 10 suffers from insufficient aroma and short-lasting aroma due to the limitation of the amount of smoke-generating agent and fragrance added caused by the processing intensity.

[0063] When a user inhales the aerosol-generated product, a negative pressure is created in the pore 12, causing the aerosol generated by the smoke-generating section 10 to penetrate into the pore 12, thereby ensuring the stability of the smoke output and aroma. At the same time, the negative pressure formed in the pore 12 also causes gas to flow into the pore 12, and the gas comes into contact with the smoke-generating section 10, increasing the oxygen content in the aerosol-generated product and helping to increase the smoke output rate of the aerosol-generated product.

[0064] In addition, in this embodiment, the extension direction of the channel 12 is consistent with the suction direction of the aerosol generated by the smoke-generating section 10, so as to form a negative pressure in the channel 12, thereby making the suction aerosol air passage unobstructed, and thus smoothly sucking the aerosol to the suction end.

[0065] In the aerosol generating product provided in this application embodiment, one of the aforementioned channels 12 can be provided in the smoke-generating substrate 11, as shown in Figures 1-3, 7-8, and 11-12; or multiple channels 12 can be provided in parallel in the smoke-generating substrate 11, for example, two, three, four, five, or six, as shown in Figures 4-6, 9-10, and 13-14, so that the gas can have more sufficient contact with the smoke-generating section 10, which helps to improve the smoke generation rate of the aerosol generating product.

[0066] In addition, in some embodiments, multiple channels 12 are provided through the smoke-generating substrate 11, and the diameter of each channel 12 is the same, so that the airflow intensity of each channel is consistent, thereby making the aerosol generated by the smoke-generating section 10 more uniform and stable.

[0067] In addition, in some embodiments, the plurality of the above-mentioned channels 12 are uniformly distributed along the cross-section of the smoke-generating section 10 perpendicular to the aerosol flow direction, and the airflow intensity in each region of the cross-section of the smoke-generating section 10 perpendicular to the aerosol flow direction tends to be consistent, which can better improve the uniformity and stability of the aerosol generated by the smoke-generating section 10.

[0068] In addition, in some embodiments, the plurality of the above-mentioned channels 12 are centrally symmetrically distributed along the cross-section of the smoke-generating section perpendicular to the aerosol flow direction, which can further improve the uniformity and stability of the aerosol generated by the smoke-generating section 10.

[0069] In addition, in some embodiments, the cross-section of the aforementioned channel can be a regular or irregular polygon, specifically a circle, triangle, quadrilateral, pentagon or pentagram, etc.

[0070] In addition, in some embodiments, the distance between the edge of the aforementioned channel and the edge of the smoke-generating section substrate is greater than or equal to 1 mm, and the distance between adjacent channels is greater than or equal to 0.5 mm, to ensure that the smoke-generating section substrate has sufficient structural strength.

[0071] In addition, in some embodiments, multiple channels 12 are provided through the smoke-generating matrix 11, and at least one channel 12 is not filled with aroma-generating filler 13. That is, in the embodiments of this application, among the multiple channels 12 provided through the smoke-generating matrix 11, at least one channel 12 is not filled with aroma-generating filler 13, and at least one channel 12 is reserved as a ventilation channel. Under the premise of ensuring normal airflow, the aroma-generating filler 13 filled in the channel 12 can continuously release fragrance, thereby effectively solving the problem that the existing solid smoke-generating section 10 has insufficient fragrance and short-lasting fragrance due to the limitation of the amount of smoke-generating agent and fragrance added caused by the processing intensity.

[0072] In some embodiments, the suction resistance of the pore 12 filled with the aroma-generating filler 13 is less than or equal to 4000 Pa, for example, it can be one or any two of the following values: 500 Pa, 1000 Pa, 1500 Pa, 1800 Pa, 2000 Pa, 3000 Pa, 4000 Pa. This not only ensures the normal flow of air and the amount of smoke generated by the aerosol product, but also allows the aroma-generating filler 13 filled in the pore 12 to continuously release fragrance, thereby effectively solving the problem that the existing solid smoke-generating section 10 has insufficient fragrance and short-lasting fragrance due to the limitation of the amount of smoke-generating agent and fragrance added caused by the processing intensity.

[0073] In addition, in some embodiments, multiple channels 12 are provided through the smoke-generating matrix 11, and at least one of the channels 12 is hollow, while the remaining channels 12 are filled with aroma-generating fillers 13. That is, in the embodiments of this application, at least one of the multiple channels 12 provided through the smoke-generating matrix 11 remains hollow or in a cavity state to serve as an airflow channel, while the other channels 12 are filled with aroma-generating fillers 13. This not only ensures the normal flow of air and the amount of smoke generated by the aerosol product, but also allows the aroma-generating fillers 13 filled in the channels 12 to continuously release fragrance, thereby effectively solving the problem that the existing solid smoke-generating section 10 suffers from insufficient fragrance and short-lasting fragrance due to the limitation of the amount of smoke-generating agent and fragrance added caused by the processing intensity.

[0074] In addition, in some embodiments, multiple channels 12 are provided through the smoke-generating substrate 11, and the smoke-generating substrate 11 is a loose porous body. That is, in the embodiments of this application, the smoke-generating substrate 11 itself is a loose porous body, which can serve as an airflow channel to ensure the normal flow of air and the amount of smoke generated by the aerosol product. The multiple channels 12 provided through the smoke-generating substrate 11 are filled with aroma-generating filler 13, which can continuously release fragrance, thereby effectively solving the problem that the existing solid smoke-generating section 10 has insufficient fragrance and short-lasting fragrance due to the limitation of the amount of smoke-generating agent and fragrance added caused by the processing intensity.

[0075] In some embodiments, the fragrance filler 13 includes a fragrance carrier portion and a first fragrance bonded to the fragrance carrier portion.

[0076] In addition, in some embodiments, the fragrance-carrying part 13 includes, but is not limited to, one or more of activated carbon, diatomaceous earth, molecular sieves, and porous polymers, which can absorb fragrance and release it slowly and evenly, especially for low-ester fragrance substances such as furanone, menthol, and ethyl maltol.

[0077] The first flavoring mentioned above includes one or more of furanone, menthol, and ethyl maltol.

[0078] In addition, in some embodiments, the aroma filler 13 filling each of the above-mentioned channels 12 accounts for 10 to 20% of the mass percentage of the smoke-generating matrix 11, for example, one or any two of the values ​​of 10%, 12%, 15%, 18%, and 20%, which can increase the loading of fragrance and flavoring while ensuring the overall structural strength of the smoke-generating section 10, thereby improving the aroma quantity and aroma persistence.

[0079] In this embodiment of the application, the shape of the smoke-generating section 10 can match the cavity of the aerosol generating device that contains the aerosol generating product. Its overall shape can be tubular as shown in Figures 1 to 6, ellipsoidal as shown in Figures 7 to 10, or spherical as shown in Figures 11 to 14.

[0080] This application embodiment also provides a method for manufacturing a smoke-generating section, as shown in Figure 15, including steps 101 to 103:

[0081] Step 101: Mix tobacco powder, tobacco flavoring substances, smoke-generating agents, fillers and binders evenly to obtain a smoke-generating matrix;

[0082] Step 102: The smoke-generating matrix is ​​stamped into a smoke-generating matrix having one or more channels;

[0083] Step 103: Fill at least one of the channels with aroma-generating filler to obtain a smoke-generating section.

[0084] In this embodiment, tobacco powder, tobacco flavoring substances, smoking agents, fillers and binders are mixed evenly, and a smoking matrix with one or more channels is prepared directly by compression molding. Then, flavoring fillers are filled into at least one channel to obtain a smoking section.

[0085] [Correction 17.11.2025 according to Rule 91] The use of compression molding method allows for diverse forms of the smoke-generating section, low loss during manufacturing, and simple manufacturing method, which is suitable for enterprises to develop differentiated products. The shape of the smoke-generating section can be matched with the receiving cavity of the aerosol generating device that contains the aerosol generating product. For example, the overall shape of the smoke-generating section can be tubular as shown in Figures 1 to 6, ellipsoidal as shown in Figures 7 to 10, or spherical as shown in Figures 11 to 14.

[0086] Meanwhile, the aforementioned channels are formed by compression molding, eliminating the need for mechanical drilling or grooving on the smoke-generating section. The channels, which penetrate the smoke-generating section, are filled with aroma-enhancing fillers. This allows the channels to simultaneously communicate with both the cavity and the suction end of the aerosol-generating product when the aerosol-generating product is placed in the receiving cavity of the aerosol-generating device. This not only enables the slow and uniform release of fragrances from the smoke-generating section, stabilizing the amount of smoke and aroma, thus improving the smoking quality, but also allows for the continuous release of aroma using the aroma-enhancing fillers. This effectively solves the problem of insufficient aroma and short-lasting fragrance in existing solid smoke-generating sections due to limitations in processing intensity and the amount of smoke-generating agents and fragrances added.

[0087] In some embodiments, when a user inhales the aerosol-generated product, a negative pressure is created in the pores, causing the aerosol generated by the smoke-generating section to penetrate into the pores, thereby ensuring the stability of the smoke output and aroma output. At the same time, the negative pressure formed in the pores also causes gas to flow into the pores, and the gas comes into contact with the smoke-generating section, increasing the oxygen content in the aerosol-generated product and helping to increase the smoke output rate of the aerosol-generated product.

[0088] In addition, in the embodiments of this application, the extension direction of the channel is consistent with the suction direction of the aerosol generated by the smoke-generating section, so as to form a negative pressure in the channel, thereby making the suction aerosol air passage unobstructed, and thus smoothly sucking the aerosol to the suction end.

[0089] In addition, the solid smoke-generating segment provided in this application does not require baking after tableting, which avoids severe volatilization of added fragrances and smoke-generating agents and minimizes the loss of volatile components.

[0090] In the aerosol generating product provided in this application embodiment, the above-mentioned channel can be provided in one smoke generating matrix or in multiple parallel arrangements within the smoke generating matrix, such as two, three, four, five or six, so that the gas can have more sufficient contact with the smoke generating section, which helps to improve the smoke generation rate of the aerosol generating product.

[0091] In addition, in some embodiments, multiple channels are provided through the smoke-generating matrix, and the diameter of each channel is the same, so that the airflow intensity of each channel is consistent, thereby making the aerosol generated by the smoke-generating section more uniform and stable.

[0092] In addition, in some embodiments, the plurality of the above-mentioned channels are uniformly distributed along the cross-section of the smoke-generating section perpendicular to the aerosol flow direction, and the airflow intensity in each region of the cross-section of the smoke-generating section perpendicular to the aerosol flow direction tends to be consistent, which can better improve the uniformity and stability of the aerosol generated by the smoke-generating section.

[0093] In addition, in some embodiments, the multiple channels described above are centrally symmetrically distributed along the cross-section of the smoke-generating section perpendicular to the aerosol flow direction, which can further improve the uniformity and stability of the aerosol generated in the smoke-generating section.

[0094] In the manufacturing method provided in this application embodiment, the amount of smoke-generating agent and fragrance added is not limited. Under the same weight, the total amount of smoke-generating agent and fragrance added to the prepared smoke-generating section can be increased to more than twice that of the smoke-generating section prepared by the prior art. This can effectively solve the problem of insufficient addition of smoke-generating agent and fragrance caused by the limitation of processing intensity in the existing smoke-generating section.

[0095] In some embodiments, step 101 above includes:

[0096] Mix tobacco powder, second flavoring, smoking agent, filler and binder in a mass ratio of (20-30):(10-20):(20-30):(10-20):(10-20).

[0097] By mixing tobacco powder, second flavoring, smoking agent, filler and binder in a mass ratio of (20-30):(10-20):(20-30):(10-20):(10-20) and controlling the moisture content to 0-5%, the obtained smoking section matrix material is not only easy to directly mold, but also ensures the amount of smoke and flavor while ensuring processing strength.

[0098] In some embodiments, the particle size of the tobacco powder, filler, and binder is 30 to 100 mesh, for example, a range of one or both of 30, 40, 50, 80, and 100 mesh. Grading the tobacco powder, filler, and binder within this particle size range ensures that the resulting smoking section matrix is ​​not only suitable for compression molding but also effectively balances processing strength and smoking rate.

[0099] In this embodiment, tobacco powder, second flavoring agent, smoke-generating agent, filler, and binder can be directly mixed evenly according to the above-mentioned mass ratio, or the tobacco powder, filler, and binder can be mixed evenly according to the above-mentioned mass ratio first, and then the tobacco flavoring substance and smoke-generating agent can be added.

[0100] In addition, in some embodiments, the pressure of the above-mentioned stamping process is 10kN to 40kN, for example, one or any two of 10kN, 15kN, 20kN, 30kN, and 40kN, which makes the prepared smoke-generating section have advantages such as loose texture, low relative density, light weight, and good adsorption effect.

[0101] In addition, in some embodiments, the second fragrance includes at least one of monomeric synthetic fragrance, natural fragrance raw material, fragrance base and fragrance essence;

[0102] In addition, in some embodiments, the smoke-generating agent includes at least one of propylene glycol and glycerin.

[0103] In some embodiments, the filler includes at least one of anhydrous lactose and microcrystalline cellulose. This ensures that the weight and volume of the smoking section are appropriate, making the smoking matrix easy to mold.

[0104] In addition, in some embodiments, the adhesive includes at least one of carboxymethyl cellulose and dextrin, which can bind the powdered raw materials into a solid and increase stability, preventing oxidation or decomposition. Furthermore, the combined effect of the filler and the adhesive gives the smoke-generating section a better moisture-proof effect.

[0105] In some embodiments, the fragrance filler includes a fragrance carrier portion and a first fragrance compounded to the fragrance carrier portion.

[0106] In addition, in some embodiments, the fragrance-carrying part 13 includes, but is not limited to, one or more of activated carbon, diatomaceous earth, molecular sieves, and porous polymers, which can absorb fragrance and release it slowly and evenly, especially for low-ester fragrance substances such as furanone, menthol, and ethyl maltol.

[0107] The first flavoring mentioned above includes one or more of furanone, menthol, and ethyl maltol.

[0108] In addition, in some embodiments, the aroma filler 13 filling each of the aforementioned channels 12 accounts for 10-20% of the mass percentage of the smoke-generating matrix 11, for example, a range of 10%, 12%, 15%, 18%, 20%, or any two of these values. This can increase the loading of fragrance and flavorings while ensuring the overall structural strength of the smoke-generating section, thereby improving the aroma quantity and aroma persistence.

[0109] In addition, in some embodiments, the aroma filler filling in all the above-mentioned channels accounts for 10-20% of the mass of the smoke-generating section, for example, one or any two of the values ​​of 10%, 12%, 15%, 18%, and 20%, which can increase the loading of fragrance and flavoring while ensuring the overall structural strength of the smoke-generating section, thereby improving the aroma quantity and aroma persistence.

[0110] The present application will be described in detail below through embodiments.

[0111] Performance testing methods

[0112] (1) The draw resistance and puff smoke concentration of the e-liquid cartridges at different smoke-generating stages were measured using an HNB draw resistance and smoke concentration tester. The test data can be read directly from the instrument. The standard deviation between the puff smoke concentration data is used to characterize the smoke generation stability. The average value of the data results is taken and summarized in Table 1. The puffing program of the HNB tester is set as follows:

[0141] Table 1

[0142] E-cigarette cartridges with a draw resistance in the range of 1000–1200 Pa provide a better overall vaping experience, and a smaller standard deviation between the individual puff smoke concentration data indicates a more stable smoke production process. In Example 2 above, the e-cigarette cartridge offers a better overall vaping experience.

[0143] This application provides an aerosol generation system 100, as shown in FIG16, including an aerosol generation device 20 and an aerosol generation article 10 in any of the above embodiments;

[0144] The aforementioned aerosol generating article 10 is installed inside the receiving cavity 21 of the aerosol generating device 20 and is completely contained within the receiving cavity 21, and is heated by the aerosol generating device 20.

[0145] In this embodiment, the aerosol-generating product includes a bare smoke-generating section without a filter or cigarette paper wrapping. The aerosol-generating device 20 includes a mouthpiece 30 connected to the outlet of the receiving cavity 21. The user can inhale the aerosol flowing out of the receiving cavity 21 through the mouthpiece 30. Since the smoke-generating section is located inside the receiving cavity, when the aerosol-generating product is heated, only the smoke-generating section is heated, thus eliminating the papery taste. Because the smoke-generating section has a channel penetrating at least one end face along the aerosol flow direction within the aerosol-generating product, once the aerosol-generating product is placed in the receiving cavity of the aerosol-generating device, the channel can simultaneously communicate with both the receiving cavity and the inhalation end of the aerosol-generating product. This allows the flavorings and fragrances in the smoke-generating section to be released slowly and evenly, stabilizing the amount of smoke and aroma, thereby improving the smoking quality.

[0146] In other embodiments, the aerosol generating article may also include a filter section connected to the smoke generating section.

[0147] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
