[0002] Aerosol generating products generally produce aerosols through heating without combustion. Specifically, aerosol generating products use an external heat source to heat the aerosol generating matrix in the product to produce aerosols.

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0050] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0051] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0052] One embodiment of this application provides an aerosol generating article 1, please refer to... Figure 1 and Figure 2 The aerosol-generating product 1 includes a filter section 15, a cooling section 14, a support section 13, a matrix section 12, and a front plug section 11 arranged sequentially along a first direction.

[0053] It should be noted that the first direction refers to Figure 1 The direction indicated by the middle arrow.

[0054] The matrix segment 12 is used to be heated by the heating element to generate an aerosol. The matrix segment 12 releases the aerosol when heated.

[0055] The aerosol generated by the matrix section 12 flows through the support section 13, the cooling section 14 and the filtration section 15 in sequence before entering the user's mouth. The multi-segment structure can extend the flow path of the aerosol and gradually reduce the temperature of the aerosol, which can reduce the problem of "burning the mouth" for the user during the inhalation process.

[0056] The support section 13 provides support and improves the structural strength of the aerosol-generated product 1.

[0057] The support section 13 and the front plug section 11 are located at both ends of the matrix section 12 along the first direction. The front plug section 11 can stop the matrix section 12, effectively reducing the possibility of the matrix section 12 shrinking and deforming and falling off after heating. In addition, the front plug section 11 can also adsorb aerosols that flow back during the process when the user is not performing suction, reducing the possibility of backflowing aerosols overflowing from the aerosol-generated product 1. Furthermore, the front plug section 11 can also absorb the condensate formed in the matrix section 12, reducing the possibility of condensate flowing out of the aerosol-generated product 1.

[0058] The cooling section 14 can cool the air. During the suction process, the airflow from the external environment can enter the cooling section 14 and mix with the aerosol, thus reducing the temperature of the aerosol.

[0059] Filter section 15 can intercept large particles carried in aerosols, improving the user's suction experience.

[0060] The support section 13, matrix section 12, and foreplug section 11 are all integrally molded structures. That is, the support section 13 is an integrally molded structure, the matrix section 12 is an integrally molded structure, and the foreplug section 11 is an integrally molded structure. The support section 13, matrix section 12, and foreplug section 11 are also separate structures, each manufactured independently.

[0061] Understandably, the one-piece molded structure has better stability and is less prone to collapse, which can improve the suction resistance consistency of the aerosol-generated product 1, thereby improving the user's suction experience.

[0062] It should be noted that there are no restrictions on the specific processing method for one-piece molding, such as extrusion molding, casting molding, roll forming, freeze forming, spray drying molding, gel forming, injection molding, die casting, and one-piece molding of composite materials.

[0063] The aerosol generating article 1 provided in this application embodiment has a one-piece molded structure for the support section 13, matrix section 12 and front plug section 11. The one-piece molded structure has good stability and the support section 13, matrix section 12 and front plug section 11 are not easy to collapse, which helps to improve the consistency of the suction resistance of the aerosol generating article 1, improve the user's suction experience, and at the same time, improve the manufacturing efficiency of the aerosol generating article 1.

[0064] One embodiment of this application provides an aerosol generation system; please refer to... Figure 13 The aerosol generation system includes an aerosol generation device 2 and an aerosol generation article 1 according to any embodiment.

[0065] The aerosol generating apparatus 2 has a receiving cavity 2a, in which at least a portion of the aerosol generating article 1 is contained. It is understood that the receiving cavity 2a provides space for the aerosol generating article 1, which may be entirely contained within the receiving cavity 2a, or partially contained within the receiving cavity 2a while the other part is located outside the receiving cavity 2a.

[0066] The aerosol generating device 2 provided in this application embodiment allows external gas to enter the receiving cavity 2a. The gas can enter the aerosol generating product 1 through the front plug section 11, which can improve the suction resistance when the user inhales and improve the user's inhalation experience.

[0067] For example, the aerosol generating device 2 includes a housing 20, which can form the appearance of the aerosol generating device 2 and can also form a receiving cavity 2a. In addition, the housing 20 can also protect the internal components of the aerosol generating device 2.

[0068] The aerosol generating device 2 includes a heating element 21, which heats the matrix segment 12 housed in the receiving cavity 2a to generate an aerosol. It is understood that the heat generated by the heating element 21 can heat and atomize the matrix segment 12, thereby generating an aerosol that can be inhaled by a user or used in medicine, beauty, etc.

[0069] The heating element 21 can be heated in various ways. For example, the heating methods include center heating and peripheral heating. Center heating refers to the heating element 21 being inserted into the aerosol-generating product 1 to bake and heat the aerosol-generating product 1 from the inside out. Peripheral heating refers to the heating element 21 being positioned around the aerosol-generating product 1 to bake and heat the aerosol-generating product 1 from the outside in. These heating methods can specifically include resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc.

[0070] It should be noted that, in this embodiment, the first direction does not specifically refer to the direction in which the aerosol generating article 1 has the longest external outline. Specifically, the arrangement direction of the filter section 15, cooling section 14, support section 13, matrix section 12, and front plug section 11 is consistent with the first direction; the direction in which the aerosol generating article 1 is inserted into the aerosol generating device 2 and the direction in which the aerosol generating article 1 is removed from the aerosol generating device 2 are both parallel to the first direction. The length of the aerosol generating article 1 along the first direction can be longer, shorter, or the same as the length in other directions.

[0071] For example, when the aerosol generating article 1 has a cylindrical outline, the first direction is the axial direction of the aerosol generating article 1. It should be noted that even when the axial length of the aerosol generating article 1 is less than its diameter, the first direction of the aerosol generating article 1 is still the axial direction. As another example, when the aerosol generating article 1 has a cuboid outline, the first direction is still the direction defined above, that is, the arrangement direction of the filter section 15, the cooling section 14, the support section 13, the matrix section 12, and the front plug section 11, or the direction in which the receiving cavity 2a takes in and places the aerosol generating article 1. The first direction of the aerosol generating article 1 can be any of the length, width, or height of the cuboid.

[0072] For example, the aerosol generating device 2 also includes a battery 22, which provides power to the aerosol generating device 2.

[0073] It should be noted that the specific structure of the matrix segment 12 is not limited here. Exemplarily, in one embodiment, the matrix segment 12 may be made of the atomizing medium itself, such as a smoky flavoring medium. In other embodiments, the matrix segment 12 may also include a matrix and an atomizing medium disposed on the matrix. The matrix may be, for example, high-temperature resistant carbon fiber. Thus, by providing a matrix, the strength of the matrix segment 12 can be improved, and it can withstand a certain degree of high temperature without producing odor.

[0074] The specific composition of the matrix segment 12 is not limited here. For example, in one embodiment, the matrix segment 12 may include plant components, smoke-generating agent components, etc.

[0075] The function of the smoke-generating agent is to produce a large amount of vapor upon heating, thereby increasing the amount of smoke in the smoke-generating product. In one embodiment, the smoke-generating agent may include, for example, one or more combinations of: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol); an ester of a polyhydric alcohol (such as glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl lauryl acetate, triacetin, meso-erythritol, a mixture of diacetins, diethyl caprylate, triethyl citrate, methyl benzoate, phenylacetic acid methyl ester, ethyl vanillate, glyceryl tributate, and lauryl acetate).

[0076] For example, the weight of the smoke-generating agent component in the matrix segment 12 accounts for no less than 10% of the total weight of the matrix segment 12. This ensures that the aerosol generated by the matrix segment 12 has a reasonable amount of smoke.

[0077] For example, the aerosol generating article 1 further includes a coating layer covering the outer periphery of the filter section 15, the cooling section 14, the support section 13, the matrix section 12, and the front plug section 11. It is understood that the coating layer can connect the filter section 15, the cooling section 14, the support section 13, the matrix section 12, and the front plug section 11, thereby improving the overall stability of the aerosol generating article 1.

[0078] The material of the wrapping layer is not limited. For example, the wrapping layer includes, but is not limited to, one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE (polyethylene), and PBAT (butylene adipate-co-terephthalate).

[0079] For example, the support segment 13, the matrix segment 12, and the foreplug segment 11 are interconnected to form a ternary composite segment. It is understood that after the support segment 13, the matrix segment 12, and the foreplug segment 11 are interconnected to form the ternary composite segment, they are then encapsulated together with the foreplug segment 11 and the filter segment 15 by an encapsulation layer to form the aerosol generating article 1. This improves the connection strength between the support segment 13, the matrix segment 12, and the foreplug segment 11, thereby increasing the structural strength of the aerosol generating article 1.

[0080] It should be noted that the specific method of connecting the support section 13, the matrix section 12, and the front plug section 11 is not limited. For example, it can be achieved by riveting, connecting with an outer covering material, or connecting with adhesive.

[0081] It should be noted that the specific shape of the aerosol-generated product 1 is not limited.

[0082] In some embodiments, please refer to Figure 1 The aerosol generating article 1 is shaped like a frustum, with its outer diameter decreasing from the front plug section 11 towards the filter section 15. This gradual reduction in diameter from the front plug section 11 to the filter section 15 allows for faster airflow through the narrower filter section 15 during suction, improving the user's suction experience. Conversely, the larger diameter of the matrix section 12 generates more aerosol, satisfying the user's need for large-volume aerosol suction. In this embodiment, the front plug section 11, matrix section 12, support section 13, cooling section 14, and filter section 15 are all frustum-shaped, and their axial directions coincide.

[0083] It should be noted that the specific diameter of the frustum is not limited. For example, the diameter of the near-lip end is 4mm to 6mm (unit of length, representing millimeters), such as 4mm, 5mm, 5.4mm, or 6mm; the diameter of the far-lip end is 6.5mm to 8mm, such as 6.5mm, 7mm, 7.2mm, or 8mm, etc. The near-lip end refers to the end of the filter section 15 that is away from the cooling section 14 along the first direction, and the far-lip end refers to the end of the front plug section 11 that is away from the matrix section 12.

[0084] In other embodiments, please refer to Figure 2 The aerosol-generating article 1 is cylindrical. This improves the uniformity of the contour of the aerosol-generating article 1 along the first direction, which on the one hand improves the cleanliness of the appearance of the aerosol-generating article 1, and on the other hand facilitates the coating layer to better cover the front plug section 11, matrix section 12, support section 13, cooling section 14 and filter section 15, thereby reducing the manufacturing difficulty of the aerosol-generating article 1.

[0085] It should be noted that, in this embodiment, the first direction is the axial direction of the front plug section 11, the matrix section 12, the support section 13, the cooling section 14, and the filter section 15. The front plug section 11, the matrix section 12, the support section 13, the cooling section 14, and the filter section 15 are all cylindrical, and their axial directions coincide.

[0086] It should be noted that the diameter of the cylinder is not limited, for example, the diameter is 4mm to 8mm, such as 4mm, 5mm, 5.4mm, 6mm or 8mm, etc.

[0087] It should be noted that the front plug section 11, the matrix section 12, the support section 13, the cooling section 14, and the filter section 15 can all be passed through by airflow. For example, during the suction process, the external airflow passes through the front plug section 11 and enters the matrix section 12. After the airflow extracts the aerosol generated by the matrix section 12, it flows out from the filter section 15 through the support section 13 and the cooling section 14.

[0088] It should be noted that the specific size of the aerosol-generated product 1 is not limited.

[0089] In some embodiments, please refer to Figure 1 and Figure 2 The dimension (hereinafter referred to as H) of the aerosol generating article 1 along the first direction is 25mm to 100mm. That is, 25mm ≤ H ≤ 100mm. For example, H can be 25mm, 35mm, 40mm, 45mm, 48mm, 54mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, or 100mm, etc. It is understandable that a reasonable length of the aerosol generating article 1 ensures that the user can smoothly draw in the aerosol while providing sufficient path for cooling, thereby improving the user's drawing experience.

[0090] For example, please refer to Figure 1 and Figure 2 The ratio of the dimension of the cooling section 14 along the first direction (hereinafter referred to as H1) to the dimension of the aerosol generating article 1 along the first direction is 5% to 60%, that is, 5% ≤ H1 / H ≤ 60%. For example, H1 / H is 5%, 15%, 20%, 25%, 30%, 35%, 40%, 50%, 55%, or 60%, etc. This makes the length of the cooling section 14 reasonable, ensuring that the cooling section 14 can effectively cool the aerosol while reducing the probability of the aerosol being condensed and trapped in the cooling section 14 in advance, improving the transmission efficiency of the cooling section 14 for the aerosol, and improving the user's suction experience.

[0091] For example, the cooling section 14 is a one-piece molded structure. It is understood that a one-piece molded structure offers better stability, ensuring the structural strength of the cooling section 14 and its ability to cool the aerosol, thereby improving the user's suction experience. Furthermore, it facilitates the manufacturing of the cooling section 14 on a factory production line, improving the manufacturing efficiency of the aerosol-generated product 1.

[0092] For example, the ring compressive strength (hereinafter referred to as P1) of the cooling section 14 along the first direction is 280 N / m to 830 N / m (N / m, representing Newtons per meter), that is, 280 N / m ≤ P1 ≤ 830 N / m. For example, P1 can be 280 N / m, 300 N / m, 350 N / m, 400 N / m, 450 N / m, 500 N / m, 600 N / m, 700 N / m, 800 N / m, or 830 N / m, etc. This makes the material density of the cooling section 14 reasonable, makes the cooling section 14 less prone to deformation during use, and reduces the manufacturing cost of the cooling section 14, making it easy to manufacture.

[0093] It should be noted that the ring pressure strength of the cooling section 14 along the first direction mentioned above refers to the maximum pressure that the cooling section 14 can withstand when subjected to pressure in the first direction until it is crushed (hereinafter referred to as F1), divided by the dimension H1 of the cooling section 14 along the first direction, i.e., P1 = F1 / H1.

[0094] In some embodiments, please refer to Figure 1 and Figure 2 The aerosol-generating product 1 is equipped with multiple airflow channels.

[0095] It should be noted that there are no restrictions on the specific type of airflow channel.

[0096] For example, all airflow channels include at least one straight channel, and / or, all airflow channels include at least one spiral channel, the spiral channel extending spirally on the outer peripheral surface of the aerosol generating article 1 or inside the aerosol generating article 1.

[0097] The above technical solutions include the following types: First, all airflow channels are straight channels; second, all airflow channels are spiral channels; third, some airflow channels are straight channels and others are spiral channels.

[0098] A straight passage refers to a passage that extends along a straight line. A straight passage can be parallel to the first direction or it can be set at an angle to the first direction.

[0099] Straight channels facilitate processing and manufacturing. Spiral channels can extend the airflow path.

[0100] For example, please refer to Figure 1 and Figure 2 The cooling section 14, the support section 13, the matrix section 12, and the front plug section 11 are each provided with an airflow channel, and the airflow channel of the upstream one is connected to the airflow channel of the downstream one among adjacent ones.

[0101] Understandably, during the user's suction process, the airflow flows from the pre-plug section 11 into the matrix section 12. After extracting aerosols in the matrix section 12, the airflow then flows sequentially through the support section 13 and the cooling section 14. In other words, the airflow sequentially flows through the pre-plug section 11, matrix section 12, support section 13, and cooling section 14. Specifically, the airflow channel of the pre-plug section 11 connects to the airflow channel of the matrix section 12, the airflow channel of the matrix section 12 connects to the airflow channel of the support section 13, and the airflow channel of the support section 13 connects to the airflow channel of the cooling section 14. This not only helps ensure consistent suction for the user but also allows external airflow to flow smoothly from the pre-plug section 11 into the matrix section 12, improving the aerosol extraction efficiency and generating more aerosols. It also allows the aerosols generated in the matrix section 12 to flow smoothly into the support section 13 and the cooling section 14 for cooling, thus improving the user's suction experience.

[0102] For example, please refer to Figure 1 , Figure 2 , Figure 9 and Figure 10 The aforementioned multiple airflow channels (i.e., all airflow channels) include a first airflow channel 141 formed in the cooling section 14. The first airflow channel 141 penetrates the end faces of both ends of the cooling section 14 along the first direction, and the first airflow channel 141 has the largest flow area among the aforementioned multiple airflow channels. It can be understood that the flow area of ​​the first airflow channel 141 (hereinafter referred to as S1) is the maximum value among all airflow channels, allowing the first airflow channel 141 to accommodate a larger amount of aerosol, enabling a larger amount of aerosol to be cooled within the first airflow channel 141, thereby improving the user's suction experience.

[0103] It should be noted that the flow area S1 of the first airflow channel 141 mentioned above refers to the area enclosed by the outer contour of the largest cross-section of the first airflow channel 141. The flow area of ​​the multiple airflow channels mentioned above refers to the area enclosed by the outer contour of the largest cross-section of each airflow channel.

[0104] In this embodiment, the cooling section 14 is provided with a side airflow channel, and the wrapping layer is provided with a first through hole. The side airflow channel connects the first through hole and the first airflow channel 141, and is used to guide the airflow from the first through hole to the first airflow channel 141. It can be understood that the external airflow entering through the first through hole can flow into the first airflow channel 141 through the side airflow channel. The external airflow can cool the aerosol in the first airflow channel 141, improve the cooling capacity of the cooling section 14, and reduce the problem of "burning the mouth" for the user during suction.

[0105] In some embodiments, please refer to Figure 1 and Figure 9The aforementioned multiple airflow channels include at least one sub-airflow channel 141a formed in the cooling section 14. The sub-airflow channel 141a penetrates the end faces of both ends of the cooling along the first direction. The ratio of the flow area of ​​any sub-airflow channel 141a (hereinafter referred to as S2) to the flow area S1 of the first airflow channel 141 is less than 33%, i.e., S2 / S1 ≤ 33%. For example, S2 / S1 is 10%, 12%, 14%, 16%, 20%, 25%, 28%, 30%, or 33%, etc.

[0106] It should be noted that the flow area S2 of the sub-airflow channel 141a mentioned above refers to the area enclosed by the outer contour at the maximum cross-section of the sub-airflow channel 141a.

[0107] In this embodiment, at least one sub-airflow channel 141a surrounds the first airflow channel 141. On the projection of the end face of the support section 13 near the cooling section 14, a portion of the support section 13 is located outside the first airflow channel 141. Aerosols extracted by the airflow through this portion of the support section 13 can enter the cooling section 14 via the sub-airflow channel 141a for user inhalation, thus improving the efficiency of aerosol extraction. Furthermore, the ratio of the flow area of ​​the sub-airflow channel 141a to the flow area S1 of the first airflow channel 141 is reasonable, ensuring that the flow rate of aerosols entering the cooling section 14 via the sub-airflow channel 141a is not excessive. This helps guarantee the cooling effect of the cooling section 14 on the aerosols and reduces the possibility of the user burning their mouth.

[0108] It should be noted that the specific number of sub-airflow channels 141a is not limited; for example, the number of sub-airflow channels 141a can be 3 to 24.

[0109] For example, please refer to Figure 1 and Figure 2 The ratio of the dimension of the support section 13 along the first direction (hereinafter referred to as H2) to the dimension of the aerosol generating article 1 along the first direction is 5% to 32%, that is, 5% ≤ H2 / H ≤ 32%. For example, H2 / H is 5%, 8%, 10%, 11%, 15%, 20%, 25%, 30%, or 32%, etc. This makes the length of the support section 13 reasonable. When the aerosol extracted from the matrix section 12 flows through the support section 13, it can not only accumulate at the support section 13, but also is less likely to cause aerosol stagnation, preventing premature condensation and interception of aerosols, thus improving the aerosol transfer efficiency of the support section 13.

[0110] For example, the support segment 13 includes a functional component. Thus, the length of the support segment 13 is reasonable, providing ample space to hold the functional component, which facilitates its continuous and slow release during inhalation, improving the user's inhalation experience. It should be noted that the functional component can be an aroma substance.

[0111] For example, the ring compression strength (hereinafter referred to as P2) of the support segment 13 along the first direction is 240 N / m to 810 N / m, that is, 240 N / m ≤ P2 ≤ 810 N / m. For example, P2 can be 240 N / m, 300 N / m, 350 N / m, 400 N / m, 450 N / m, 500 N / m, 600 N / m, 700 N / m, 800 N / m, or 810 N / m, etc. This makes the material density of the support segment 13 reasonable, making it less prone to deformation during use and providing good support for the aerosol-generated product 1. In addition, it also makes the manufacturing cost of the cooling segment 14 lower and facilitates its production.

[0112] It should be noted that the ring compression strength of the support segment 13 along the first direction mentioned above refers to the maximum pressure that the support segment 13 can withstand when it is subjected to pressure in the first direction until it is crushed (hereinafter referred to as F2), divided by the dimension H2 of the support segment 13 along the first direction, i.e., P2 = F2 / H2.

[0113] For example, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 The aforementioned multiple airflow channels include at least one second airflow channel 131 formed in the support section 13. The second airflow channel 131 penetrates the end faces of both ends of the support section 13 along the first direction. The ratio of the flow area of ​​any second airflow channel 131 (hereinafter referred to as S3) to the flow area S1 of the first airflow channel 141 is 0.6% to 85%, that is, 0.6% ≤ S3 / S1 ≤ 85%. For example, S3 / S2 is 0.6%, 5%, 10%, 12%, 14%, 16%, 20%, 25%, 28%, 30%, 35%, 40%, 50%, 51%, 54%, 60%, 70%, 76%, or 85%, etc.

[0114] Understandably, the second airflow channel 131, penetrating the end faces of the support section 13 at both ends along the first direction, helps improve the air permeability of the support section 13 and enhance the user's suction experience. The ratio of the flow area S3 of the second airflow channel 131 to the flow area S1 of the first airflow channel 141 is reasonable, ensuring a suitable flow area for the second airflow channel 131. This improves the air permeability of the support section 13 while maintaining its structural strength. It also allows the aerosol generated by the matrix section 12 to flow through the support section 13 at a reasonable flow rate, reducing the possibility of aerosol accumulation in the support section 13 and preventing excessive flow of aerosol through the support section 13. This facilitates a stable supply of aerosol generated by the matrix section 12 to the user's suction, improving suction consistency.

[0115] It should be noted that the flow area S3 of the second airflow channel 131 mentioned above refers to the area enclosed by the outer contour at the maximum cross-section of the second airflow channel 131.

[0116] It should be noted that the specific number of the second airflow channels 131 is not limited; for example, the number of the second airflow channels 131 can be 1 to 157.

[0117] For example, please refer to Figure 1 and Figure 2 The ratio of the dimension of the matrix segment 12 along the first direction (hereinafter referred to as H3) to the dimension of the aerosol generating article 1 along the first direction is 15% to 55%, that is, 15% ≤ H3 / H ≤ 55%. For example, H3 / H can be 15%, 20%, 25%, 30%, 35%, 40%, 50%, 51%, or 55%, etc. This ensures that the length of the matrix segment 12 is reasonable, allowing the aerosol generating article 1 to have sufficient matrix segment 12 to generate sufficient aerosol. In addition, it also ensures that the suction resistance of the matrix segment 12 is reasonable, which is beneficial for users to extract aerosols during the suction process.

[0118] For example, the ring crush strength (hereinafter referred to as P3) of the matrix segment 12 along the first direction is 80 N / m to 810 N / m, that is, 80 N / m ≤ P3 ≤ 810 N / m. For example, P3 can be 80 N / m, 100 N / m, 150 N / m, 200 N / m, 250 N / m, 300 N / m, 350 N / m, 400 N / m, 450 N / m, 500 N / m, 600 N / m, 700 N / m, 800 N / m, or 810 N / m, etc. This makes the material density of the matrix segment 12 reasonable, making the matrix segment 12 less prone to deformation during heating and able to stably produce aerosol. In addition, it also makes the air permeability of the matrix segment 12 reasonable, which facilitates the extraction of aerosol by airflow.

[0119] It should be noted that the ring compression strength of the matrix segment 12 along the first direction mentioned above refers to the maximum pressure that the matrix segment 12 can withstand when subjected to pressure in the first direction until it collapses (hereinafter referred to as F3), divided by the dimension H3 of the support segment 13 along the first direction, i.e., P3 = F3 / H3.

[0120] For example, please refer to Figure 1 and Figure 2 The aforementioned multiple airflow channels include at least one third airflow channel 121 formed in the matrix segment 12. The third airflow channel 121 penetrates the end faces of both ends of the matrix segment 12 along the first direction. The ratio of the flow area of ​​any third airflow channel 121 (hereinafter referred to as S4) to the flow area S1 of the first airflow channel 141 is 0.3% to 33%, that is, 0.3% ≤ S4 / S1 ≤ 33%. For example, S4 / S1 is 0.3%, 3%, 10%, 12%, 14%, 16%, 20%, 25%, 28%, 30%, or 33%, etc.

[0121] It should be noted that the flow area S4 of the third airflow channel 121 mentioned above refers to the area enclosed by the outer contour at the maximum cross-section of the third airflow channel 121.

[0122] It should be noted that the specific number of the third airflow channels 121 is not limited; for example, the number of the third airflow channels 121 can be 3 to 256.

[0123] In some embodiments, please refer to Figure 1 and Figure 2 The ratio of the dimension of the front plug section 11 along the first direction (hereinafter referred to as H4) to the dimension of the aerosol generating product 1 along the first direction is 5% to 32%, that is, 5% ≤ H4 / H ≤ 32%. For example, H4 / H is 5%, 8%, 10%, 11%, 15%, 20%, 25%, 30%, or 32%, etc. This ensures that the length of the front plug section 11 is reasonable and the structural strength of the front plug section 11 is appropriate, which can ensure that the aerosols that flow back during non-vacuuming processes can be adsorbed by the front plug section 11 as much as possible, reducing the possibility of condensate accumulation in the containment cavity of the aerosol generating device caused by the backflowing aerosols, and maintaining the cleanliness of the containment cavity of the aerosol generating device.

[0124] In some embodiments, the ring compression strength (hereinafter referred to as P4) of the fore-plug section 11 along the first direction is 80 N / m to 680 N / m, that is, 80 N / m ≤ P4 ≤ 680 N / m. For example, P4 can be 80 N / m, 100 N / m, 150 N / m, 200 N / m, 250 N / m, 300 N / m, 350 N / m, 400 N / m, 450 N / m, 500 N / m, 600 N / m, or 680 N / m, etc. This ensures that the material density and structural strength of the fore-plug section 11 are reasonable, thereby preventing deformation during use and improving the stability of the fore-plug section 11.

[0125] It should be noted that the ring pressure strength of the front plug section 11 along the first direction mentioned above refers to the maximum pressure that the front plug section 11 can withstand when subjected to pressure in the first direction until it is crushed (hereinafter referred to as F4), excluding the dimension H4 of the front plug section 11 along the first direction, i.e., P4 = F4 / H4.

[0126] For example, please refer to Figure 1 and Figure 2 The aforementioned multiple airflow channels include at least one fourth airflow channel 111 formed in the front plug section 11. The fourth airflow channel 111 penetrates the end faces of both ends of the front plug section 11 along the first direction. The ratio of the flow area of ​​any fourth airflow channel 111 (hereinafter referred to as S5) to the flow area S1 of the first airflow channel 141 is 0.6% to 66.6%, that is, 0.6% ≤ S5 / S1 ≤ 66%. For example, S5 / S1 can be 0.6%, 3%, 10%, 12%, 14%, 16%, 20%, 25%, 28%, 30%, 35%, 40%, 50%, 51%, 54%, 60%, or 66%, etc.

[0127] Understandably, the fourth airflow channel 111 improves the permeability of the front plug section 11, facilitating the flow of air from the external environment into the matrix section 12 to extract aerosols, thus facilitating user suction. Furthermore, the ratio of the flow area S5 of the fourth airflow channel 111 to the flow area of ​​the first airflow channel 141 is reasonable, ensuring that the fourth airflow channel 111 has a suitable flow area. This improves the permeability of the front plug section 11 while maintaining its structural strength, thereby increasing aerosol extraction efficiency and enhancing the user's suction experience.

[0128] It should be noted that the flow area S4 of the fourth airflow channel 111 mentioned above refers to the area enclosed by the outer contour at the maximum cross-section of the fourth airflow channel 111.

[0129] It should be noted that the specific number of the fourth airflow channels 111 is not limited; for example, the number of the fourth airflow channels 111 can be 1 to 157.

[0130] For example, please refer to Figure 1 and Figure 2 The ratio of the dimension of the filter section 15 along the first direction (hereinafter referred to as H5) to the dimension of the aerosol generating article 1 along the first direction is 10% to 60%, that is, 10% ≤ H5 / H ≤ 60%. For example, H5 / H is 10%, 15%, 20%, 25%, 30%, 35%, 40%, 50%, 55%, or 60%, etc. This makes the length of the filter section 15 reasonable, ensuring that the filter section 15 can effectively screen large molecules in the aerosol while maintaining the permeability of the aerosol, reducing the possibility of aerosol being trapped in the filter section 15, improving the aerosol transmission efficiency of the filter section 15, and improving the user's suction experience.

[0131] In some embodiments, the filter section 15 is a one-piece molded structure. It is understood that a one-piece molded structure has better stability, which can ensure the structural strength of the filter section 15 and its filtration capacity for aerosols, thereby improving the user's suction experience and increasing the manufacturing efficiency of the aerosol-generating product 1.

[0132] For example, the ring compression strength (hereinafter referred to as P5) of the filter section 15 along the first direction is 170 N / m to 640 N / m, that is, 170 N / m ≤ P5 ≤ 640 N / m. For example, P4 can be 170 N / m, 200 N / m, 250 N / m, 300 N / m, 350 N / m, 400 N / m, 450 N / m, 500 N / m, 600 N / m, or 640 N / m, etc. This makes the material density of the filter section 15 reasonable, and the structural strength of the filter section 15 reasonable, so as to ensure that the filter section 15 is not easily deformed during use and improve the stability of the filter section 15.

[0133] It should be noted that the ring pressure strength of the filter section 15 along the first direction mentioned above refers to the maximum pressure that the filter section 15 can withstand when subjected to pressure in the first direction until it is crushed (hereinafter referred to as F5), divided by the dimension H5 of the filter section 15 along the first direction, i.e., P5 = F5 / H5.

[0134] For example, please refer to Figure 1 and Figure 11 The aforementioned plurality of airflow channels include at least one fifth airflow channel 151 formed in the filter section 15, the fifth airflow channel 151 penetrating the end faces of both ends of the filter section 15 along the first direction.

[0135] Understandably, the fifth airflow channel 151 passing through the end faces of the filter section 15 at opposite ends along the first direction helps to reduce the suction resistance of the filter section 15 and improve the user's suction experience.

[0136] It should be noted that the specific number of the fifth airflow channels 151 is unlimited.

[0137] In some specific embodiments, please refer to Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 10 and Figure 11 The aerosol-generating product 1 is a frustum, with a diameter of 5.4 mm near the lip and 7.2 mm at the distal lip.

The front plug section 11 has 7 sub-airflow channels 111, 4 of which are circular straight channels with a diameter of 2.0 mm and 3 are circular spiral channels with a diameter of 0.5 mm. The filter section 15 has 12 sub-airflow channels 151 with a diameter of 0.3 mm and a diameter of 0.3 mm.

[0138] In other specific embodiments, please refer to Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 and Figure 12The aerosol-generated product 1 is cylindrical with a diameter of 5.4 mm and a dimension of 82 mm along the first direction.

The cooling section 14, support section 13, matrix section 12, and front plug section 11 are sequentially formed by extrusion molding, injection molding, extrusion molding, and casting molding. The ring compression strengths of the filter section 15, cooling section 14, support section 13, matrix section 12, and front plug section 11 are 320 N / m, 447 N / m, 516 N / m, 432 N / m, and 347 N / m, respectively.
