Abstract
Description
Technical Field
[0001] This application relates to the field of smoke-generating products, and in particular to an aerosol-generating product and an aerosol-generating system. Background Technology
[0002] Smoke-generating products include aerosol-generating products that form aerosols by heating without combustion. During the use of an aerosol-generating product, heat is transferred from a heat source to the medium section of the aerosol-generating product, causing the medium section to release volatile compounds. These volatile compounds are carried into the air containing the aerosol-generating product when the user inhales it. As the released volatile compounds cool, they condense to form aerosols.
[0003] In related technologies, the air intake ratio between the near-lip and far-lip ends of aerosol-generating products fluctuates, thus affecting the amount of aerosol generated and the inhalation experience. Utility Model Content
[0004] In view of this, the embodiments of this application aim to provide an aerosol generating article and an aerosol generating system, which are intended to help increase the amount of aerosol generated and improve the smoking experience.

[0015] In some embodiments, the front plug section is an airtight layer, the airtight layer is provided with the first air inlet hole, and the first air inlet hole on the airtight layer penetrates the distal lip end of the airtight layer.
[0016] In some embodiments, the air-impermeable layer is cross-sectioned with a plane perpendicular to the axial direction of the aerosol-generating article. On the cross-section, the sum of the flow cross-sectional areas of each of the first air inlets is the first area, and the area of the region enclosed by the outer contour of the cross-section of the air-impermeable layer is the second area. The first area accounts for 5% to 30% of the second area.
[0017] In some embodiments, the airtight layer is transversely cut by a plane perpendicular to the axial direction of the aerosol-generating article. In the cross-section, the flow cross-section of each of the first air inlets is arc-shaped, and the center of each arc-shaped flow cross-section is located on the central axis of the front plug section. At least a portion of the arc-shaped flow cross-sections are located on the same circumference.
[0018] In some embodiments, the arc-shaped flow cross sections are distributed in a radial pattern.
[0019] In some embodiments, the air inlet further includes a second air inlet disposed in the medium segment, the second air inlet extending radially along the medium segment and penetrating the peripheral sidewall of the medium segment.
[0020] In some embodiments, the maximum cross-sectional area of the second air inlet is no greater than 0.0225 mm. 2 ; and / or,
[0021] The distance between the central axis of the second air inlet and the distal lip of the medium segment in the axial direction of the aerosol generating article is a first dimension, and the dimension of the medium segment in the axial direction of the aerosol generating article is a second dimension, wherein the ratio of the first dimension to the second dimension is not less than 1 / 4.
[0022] This application also provides an aerosol generation system, including:
[0023] An aerosol generating device is provided with a receiving chamber, and the aerosol generating device includes a heating component;

The inlet of the at least one first air inlet is located at the distal lip end of the front plug section; and / or, the inlet of the at least one first air inlet is located on the peripheral sidewall between the distal lip end of the front plug section and the distal lip end of the medium section. During the aerosol extraction process, air can reach the distal lip end of the medium section through the first air inlet. The airflow entering the aerosol generating article through the first air inlet ensures the amount of airflow entering the medium section, thus helping to guarantee the amount of aerosol generated. Simultaneously, the first air inlet can also reduce the suction resistance of the aerosol generating article, thereby improving the suction experience of the aerosol generating article.

[0048] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0049] This application provides an aerosol-generating product. Please refer to [link / reference]. Figures 1 to 3 , Figure 5 The aerosol generating product 100 includes a medium section 10 and a front plug section 20 located upstream of the medium section 10.
[0050] Medium section 10 is used to generate aerosols. For details, please refer to [link / reference]. Figures 6 to 9 The aerosol generating article 100 is used in conjunction with the aerosol generating device 200, which includes a heating component 204 and a power supply component. The power supply component provides electrical energy to the heating component 204, which converts the electrical energy into other forms of energy and applies them to the medium section 10, thereby heating the medium section 10 to generate aerosols.
[0051] The heating component 204 can employ various heating methods. Exemplarily, these include peripheral heating and center heating. Peripheral heating refers to the heating component 204 being positioned around the aerosol-generating article 100 to bake and heat the medium segment 10 from the outside in. Center heating refers to the heating component 204 being inserted into the aerosol-generating article 100 to bake and heat the medium segment 10 from the inside out. These heating methods can specifically include resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc., and are not specifically limited herein.
[0052] Each structural segment of the aerosol generating article 100, as well as the aerosol generating article 100 itself, has a proximal lip end and a distal lip end. Specifically, taking the medium segment 10 as an example, the two ends of the medium segment 10 in the axial direction are the proximal lip end and the distal lip end, respectively. The proximal lip end refers to the end of the medium segment 10 that is close to the user's lips when the user uses the aerosol generating article 100, and the distal lip end refers to the end of the medium segment 10 that is far away from the user's lips when the user uses the aerosol generating article 100.
[0053] It is understandable that the front plug section 20 is the structural segment between the distal lip end of the aerosol generating product 100 and the medium section 10. In other words, the distal lip end of the front plug section 20 is the distal lip end of the aerosol generating product 100. During use, the front plug section 20 effectively reduces the probability of the medium section 10 falling off. Furthermore, the front plug section 20 effectively prevents aerosol condensation from flowing downwards and remaining in the receiving chamber 201 of the aerosol generating device 200, thus avoiding contamination and difficulty in cleaning the receiving chamber 201, and preventing cross-contamination of flavors when inhaling different flavored aerosol generating products 100. The medium section 10 and the front plug section 20 are connected axially along the aerosol generating product 100.
[0054] It should be noted that, in this embodiment, the axial direction of the aerosol generating article 100 is the first direction. The axial direction of each structural segment of the aerosol generating article 100 is parallel to the first direction. Specifically, the first direction is as follows: Figures 1 to 3 , Figure 5 The direction indicated by L. That is, the front plug section 20 is located at one end of the axial direction of the medium section 10.
[0055] The aerosol generating article 100 is provided with an air inlet 100c, which includes at least one first air inlet 100d. Specifically, at least a portion of the wall of the first air inlet 100d is a structure of the front plug section 20. Here, the first air inlet 100d may be entirely located on the front plug section 20, or the front plug section 20 and other structures (e.g., the medium section 10) may jointly define the first air inlet 100d.
[0056] Wherein, the inlet of at least one first air inlet 100d is located at the distal lip end of the front plug section 20; and / or, the inlet of at least one first air inlet 100d is located on the peripheral sidewall between the distal lip end of the front plug section 20 and the distal lip end of the medium section 10.
[0057] External air can enter the first air inlet 100d through the inlet of the first air inlet 100d.
[0058] Here are three implementation methods:
[0059] The first type: the aerosol generating article 100 is provided with at least one first air inlet 100d, the first air inlet 100d is provided in the front plug section 20, and the inlet of the first air inlet 100d is located at the distal lip end of the aerosol generating article 100.
[0060] The second type: the aerosol generating article 100 is provided with at least one first air inlet 100d, the first air inlet 100d is provided in the front plug section 20, and the inlet of the first air inlet 100d is located on the peripheral side wall of the front plug section 20.
[0061] The third type: the aerosol generating article 100 is provided with at least one first air inlet 100d, which is located between the proximal lip end of the front plug section 20 and the distal lip end of the medium section 10, and the inlet of the first air inlet 100d is formed by the peripheral sidewall between the proximal lip end of the front plug section 20 and the distal lip end of the medium section 10.
[0062] The fourth type: The aerosol generating article 100 is provided with at least two first air inlets 100d. One of the first air inlets 100d is located in the front plug section 20 and the inlet is located at the distal lip end of the front plug section 20; the other first air inlet 100d may be located in the front plug section 20, or it may be formed by the front plug section 20 and other structures of the aerosol generating article 100 (e.g., the medium section 10), but its inlet needs to be located on the peripheral sidewall between the distal lip end of the front plug section 20 and the distal lip end of the medium section 10.
[0063] It should be noted that each structural segment of the aerosol generating product 100 (such as the medium segment 10, the fore plug segment 20, etc.) can be cylindrical. Specifically, taking the fore plug segment 20 as an example, based on the cylindrical structure of the fore plug segment 20, the peripheral sidewall of the fore plug segment 20 is the cylindrical surface of the cylinder, and the two axial end faces of the fore plug segment 20 are circular.
[0064] In this way, when aerosol is drawn in, the airflow can enter the interior of the aerosol generating article 100 through the first air inlet 100d and reach the distal lip of the medium section 10. After this part of the airflow enters the interior of the aerosol generating article 100, it can flow approximately along the axial direction of the aerosol generating article 100 towards the proximal lip of the aerosol generating article 100.
[0065] The air intake ratio at the distal and proximal ends of the aerosol generating article 100 significantly affects the amount of aerosol generated and the inhalation experience. However, in related technologies, due to uneven filling material in the pre-plug section, the air intake at the distal end of the aerosol generating article is uncontrollable. For example, after the aerosol generating article rotates inside the aerosol generating device, the air intake ratio at the proximal and distal ends may fluctuate, thus affecting the amount of aerosol generated and the inhalation experience.
[0066] The aerosol generating article 100 of this application embodiment is provided with an air inlet 100c, which includes at least one first air inlet 100d. The inlet of at least one first air inlet 100d is located at the distal lip end of the front plug section 20; and / or, the inlet of at least one first air inlet 100d is located on the peripheral sidewall between the distal lip end of the front plug section 20 and the distal lip end of the medium section 10. During the aerosol extraction process, air can reach the distal lip end of the medium section 10 through the first air inlet 100d. The airflow entering the aerosol generating article 100 through the first air inlet 100d ensures a sufficient amount of airflow entering the medium section 10, thus facilitating the generation of aerosols. Simultaneously, the first air inlet 100d can also reduce the suction resistance of the aerosol generating article 100, thereby improving the suction experience of the aerosol generating article 100.
[0067] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The material of the front plug section 20 is one of thermoplastic polyester, cellulose acetate, silicone, and polylactic acid.
[0068] Cellulose acetate (CA) has a relatively low moisture regain, which helps to improve the moisture-proof performance of the aerosol-generating product 100. In addition, cellulose acetate is not easy to age or burn, which helps to improve the reliability of the front plug section 20.
[0069] Thermoplastic polyesters can be, for example, polyethylene terephthalate (PET) or polybutylene terephthalate (PBT). Thermoplastic polyesters possess certain hardness and strength, as well as certain heat resistance, which helps improve the structural stability and reliability of the foreplug section 20. Furthermore, thermoplastic polyesters have good processing properties, which facilitates the production and molding of the foreplug section 20.
[0070] Polylactic acid (PLA) is polymerized from lactic acid molecules. Its sources are relatively wide, which helps to reduce the production cost of the pre-plug section 20. At the same time, PLA is also a biodegradable material, which is more environmentally friendly.
[0071] Silica gel possesses high mechanical strength and good air permeability, which helps to improve the structural strength of the front plug section 20 and reduce its suction resistance. Furthermore, silica gel is a highly active adsorbent material, enabling it to filter or adsorb aerosols, thus improving aerosol quality and the ease of cleaning of the aerosol-generated product 100.
[0072] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 Along the first direction, the size of the front plug section 20 is 3mm to 10mm. For example, it is 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, etc.
[0073] In this embodiment, on the one hand, the front plug section 20 is not too short, which makes it easy to operate during its production process and helps to improve the production efficiency of the front plug section 20. At the same time, the dimensional tolerance accuracy of the front plug section 20 produced is more conducive to meeting the standards and improving the yield of the front plug section 20. On the other hand, the front plug section 20 is not too long, which helps to control the production cost of the front plug section 20.
[0074] Preferably, along the first direction, the size of the front plug section 20 is between 3mm and 7mm.
[0075] In some embodiments, please refer to Figures 1 to 5 In some embodiments, the number of first air inlets 100d is not less than two. For example, there are 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.
[0076] By providing at least two first air inlets 100d, there are at least two streams of airflow entering the aerosol generating product 100 through the first air inlets 100d. With at least two streams of airflow, effective turbulence is generated inside the aerosol generating product 100, which facilitates the uniform entry of airflow into the medium section 10, thereby promoting the generation of aerosols.
[0077] Preferably, the number of first air inlets 100d is not less than 4.
[0078] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5The maximum cross-sectional area of a single first air inlet 100d is 0.0064mm. 2 -0.25mm 2 .
[0079] The maximum cross-sectional area of a single first air inlet 100d can be 0.0064mm. 2 0.008mm 2 0.01mm 2 0.04mm 2 0.05mm 2 0.08mm 2 0.09mm 2 0.1mm 2 0.12mm 2 0.13mm 2 0.15mm 2 0.18mm 2 0.2mm 2 0.22mm 2 0.23mm 2 0.25mm 2 The point value of any one of them or the point value between any two.
[0080] It should be noted that the maximum cross-sectional area of a single first air inlet 100d refers to the area of the largest cross-section among all the cross-sections of the first air inlet 100d. Here, the cross-section of the first air inlet 100d is its flow section.
[0081] With a fixed intake area, the smaller the flow cross-sectional area of a single first intake hole 100d, the more first intake holes 100d need to be set; the larger the flow cross-sectional area of a single first intake hole 100d, the fewer first intake holes 100d need to be set.
[0082] In this embodiment, the maximum cross-sectional area of a single first air inlet 100d is set to 0.0064 mm. 2 -0.25mm 2 While enabling the aerosol generating product 100 to have a certain air intake efficiency, it can also enable the aerosol generating product 100 to have a certain structural strength. In addition, by controlling the number of the first air inlet 100d, the production efficiency of the aerosol generating product 100 can be improved.
[0083] Furthermore, if the cross-sectional area of a single first air inlet 100d is too small, the air intake will be insufficient; while if the cross-sectional area of a single first air inlet 100d is too large, the airflow velocity during the intake process will be too slow, which is not conducive to the aerosol's flavor absorption. In this embodiment, the maximum cross-sectional area of a single first air inlet 100d is set to be not less than 0.0064 mm.2 And not greater than 0.25mm 2 This will help improve the situation.
[0084] Preferably, the maximum cross-sectional area of a single first air inlet 100d is 0.01mm. 2 -0.09mm 2 .
[0085] While enabling the aerosol generating product 100 to have a certain air intake efficiency, it also helps to further improve the production efficiency of the aerosol generating product 100.
[0086] More preferably, the maximum cross-sectional area of a single first air inlet 100d is 0.01mm. 2 -0.04mm 2 .
[0087] While enabling the aerosol generating product 100 to have a certain air intake efficiency, it also helps to further improve the production efficiency of the aerosol generating product 100.
[0088] In some embodiments, please refer to Figure 1 The medium section 10 and the front plug section 20 define a first air inlet 100d at their junction.
[0089] For example, the end face of the distal lip of the medium section 10, except for the area used to form the inner wall of the first air inlet 100d, is a mating surface, and the front plug section 20 can completely cover the mating surface.
[0090] Thus, the area of the front plug section 20 other than that used to form the first air inlet 100d can be a solid structure. By making the front plug section 20 a solid structure, it is beneficial to improve the liquid-proof performance of the aerosol-generating product 100.
[0091] "Solid structure" means that the interior of the fore-plug section 20 has no obvious gaps or holes, and the material used to prepare the fore-plug section 20 is continuously distributed in space. It can be understood that the interior of the fore-plug section 20 may have micropores. These micropores are the pores of the material of the fore-plug section 20 itself. These micropores constitute air passages, and a portion of the airflow can also flow from one end of the fore-plug section 20 axially to the other end through these air passages.
[0092] Understandably, since the suction resistance of the front plug section 20 is generally large, the airflow has difficulty passing through the air passage holes inside the front plug section 20. When there is no first air inlet 100d at the junction of the medium section 10 and the front plug section 20, if the end face of the medium section 10 is completely covered by the front plug section 20, the airflow entering the front plug section 20 will also have difficulty entering the medium section 10.
[0093] In this embodiment, the first air inlet 100d is located at the junction of the front plug section 20 and the medium section 10. That is, the end face of the distal lip of the medium section 10 forms part of the inner wall of the first air inlet 100d. In this way, the airflow entering the first air inlet 100d can directly contact the medium section 10, thereby making it easier to enter the medium section 10. This helps to ensure the amount of aerosol generated and improve the sucking experience.
[0094] In some embodiments, please refer to Figure 2 and Figure 5 The front plug section 20 is provided with an internal air passage 20a, which extends along the axial direction of the front plug section 20 and penetrates the near lip end of the front plug section 20; at least one first air inlet 100d is provided in the front plug section 20, and one end of the first air inlet 100d provided in the front plug section 20 penetrates the peripheral sidewall of the front plug section 20, and the other end communicates with the internal air passage 20a.
[0095] It should be noted that, in the embodiments of this application, the axial direction of the front plug section 20 is the same as the axial direction of the aerosol generating article 100, which is also the first direction.
[0096] In this way, at least a portion of the airflow entering the aerosol generating article 100 through the first air inlet 100d can enter the internal air passage 20a, and flow through the internal air passage 20a before entering the medium section 10.
[0097] Flavor-adjusting ingredients can be added to the internal airway 20a. The airflow entering the internal airway 20a mixes with the flavor ingredients in the internal airway 20a and then enters the medium section 10 together. This is beneficial for the expression of flavor components.
[0098] In some embodiments, please refer to Figure 3 and Figure 4 The front plug section 20 is an airtight layer 21. The airtight layer 21 is provided with a first air inlet 100d, and the first air inlet 100d on the airtight layer 21 penetrates the distal lip end of the airtight layer 21.
[0099] The air-impermeable layer 21 can be, for example, an air-impermeable membrane, an air-impermeable paper, or an air-impermeable coating, etc.
[0100] Using an impermeable layer 21 as the fore-stop section 20 helps to further reduce the chance of condensate leakage into the containment chamber 201. However, the impermeable layer 21 has a greater suction resistance. After using the impermeable layer 21 as the fore-stop section 20, it needs to be designed reasonably to ensure the amount of aerosol generated and the suction experience.
[0101] The first air inlet 100d on the air-impermeable layer 21 extends along the axial direction of the aerosol-generating article 100 and penetrates through the opposite ends of the air-impermeable layer 21.
[0102] In this embodiment, by opening a first air inlet 100d on the air-impermeable layer 21, air can flow through the air-impermeable layer 21 through the first air inlet 100d and enter the medium section 10, thus providing air for generating aerosols for the aerosol generating article 100.
[0103] In some embodiments, please refer to Figure 3 and Figure 4 The airtight layer 21 is cross-sectioned with a plane perpendicular to the axial direction of the aerosol-generating product 100. On this cross-section, the sum of the flow cross-sectional areas of each of the first air inlets 100d is the first area, and the area enclosed by the outer contour of the airtight layer 21 is the second area. The first area accounts for 5% to 30% of the second area. For example, it can be 5%, 7%, 9%, 10%, 12%, 14%, 16%, 18%, 20%, 21%, 23%, 25%, 27%, 29%, 30%, etc.
[0104] Here, the first area can be controlled within a reasonable range. On the one hand, the first area will not be too small, which will facilitate sufficient air to pass through the impermeable layer 21 and enter the medium section 10, thereby ensuring the amount of aerosol generated; on the other hand, the first area will not be too large, which will help ensure the strength of the impermeable layer 21, and also help ensure the impermeability of the aerosol-generating product 100.
[0105] In some embodiments, please refer to Figure 3 and Figure 4 The airtight layer 21 is transversely cut by a plane perpendicular to the axial direction of the aerosol generating product 100. In the cross section, the shape of the flow section of each first air inlet 100d is arc-shaped, and the center of each arc-shaped flow section is located on the central axis of the front plug section 20. At least some of the arc-shaped flow sections are located on the same circumference.
[0106] The dimensions of each first air inlet 100d located on the same circumference can be the same, and they can be evenly distributed along the circumference. For example, please refer to... Figure 4 On the same circumference, the airtight layer 21 is provided with four first air inlets 100d.
[0107] In this embodiment, air enters through multiple first air inlets 100d on the same circumference, which helps to improve the uniformity of air intake in the aerosol-generating product 100.
[0108] In some embodiments, please refer to Figure 3 and Figure 4 Each arc-shaped flow section is distributed in a radial pattern.
[0109] Here, all the arc-shaped flow sections are centered on the same circle. All the arc-shaped flow sections are divided into multiple groups, with the arc-shaped flow sections within each group located on the same circumference, and the arc-shaped flow sections between different groups located on different circumferences.
[0110] It is understandable that the arc-shaped flow sections of each group can be evenly distributed in the radial direction of the impermeable layer 21.
[0111] In this embodiment, air intake can be achieved relatively uniformly in both the radial and circumferential directions of the airtight layer.
[0112] In some embodiments, please refer to Figure 2 The air inlet 100c also includes a second air inlet 10a provided in the medium section 10. The second air inlet 10a extends radially along the medium section 10 and penetrates the peripheral sidewall of the medium section 10.
[0113] When the medium segment 10 is in the form of a one-piece columnar structure, or is filled with sheets, tobacco shreds, granules, etc., there are certain gaps in the medium segment 10, allowing air to flow between them. Therefore, an air inlet 100c can also be provided on the medium segment 10, which is the second air inlet 10a. Preferably, when the medium segment 10 is a structure with a special shape (e.g., the medium segment 10 has macroscopic air passages running through both ends of its axial direction) obtained by a one-piece casting or extrusion process, for example, the macroscopic air passages can be constructed in the medium segment 10 to form an air path.
[0114] In this way, air can also enter the medium section 10 through the second air inlet 10a. The first air inlet 100d and the second air inlet 10a work together to better control the air intake of the aerosol generating product 100.
[0115] In some embodiments, please refer to Figure 2 The maximum cross-sectional area of the second air inlet 10a is no greater than 0.0225 mm. 2 For example, 0.01mm 2 0.012mm 2 0.013mm 2 0.014mm 2 0.015mm 2 0.016mm 2 0.017mm 2 0.018mm 2 0.019mm 2 0.02mm 2 0.021mm 2 0.022mm 2 0.0225mm 2 etc.
[0116] Here, the explanation of the maximum cross-sectional area of the second air inlet 10a can be understood by referring to the explanation of the maximum cross-sectional area of the first air inlet 100d above, and will not be repeated here.
[0117] This helps to control the air entering the aerosol generating product 100 through the second air inlet 10a within a suitable range, thereby improving the problem of uneven heating in different areas of the medium section 10 caused by the turbulence generated by the air entering through the second air inlet 10a and the air entering through the first air inlet 100d. This helps to reduce the impact on the amount of aerosol generated and the aroma expression of the aerosol.
[0118] In some embodiments, please refer to Figure 2 The distance between the central axis of the second air inlet 10a and the distal lip of the medium section 10 along the axial direction of the aerosol generating article 100 is the first dimension, and the dimension of the medium section 10 along the axial direction of the aerosol generating article 100 is the second dimension. The ratio of the first dimension to the second dimension is not less than 1 / 4. For example, it can be 1 / 4, 11 / 40, 3 / 10, 13 / 40, 1 / 3, 7 / 20, 3 / 8, 2 / 5, 17 / 40, 9 / 20, 19 / 40, 1 / 2, etc.
[0119] This helps to control the distance between the second air inlet 10a and the front plug section 20 within a suitable range, thereby improving the problem of uneven heating in different areas of the medium section 10 caused by the turbulence generated by the air entering through the second air inlet 10a and the air entering through the first air inlet 100d. This helps to reduce the impact on the amount of aerosol generated and the aroma expression of the aerosol.
[0120] This application also provides an aerosol generation system. Please refer to [link / reference]. Figures 6 to 9 The aerosol generation system includes an aerosol generation device 200 and an aerosol generation article 100 according to any embodiment of this application.
[0121] The aerosol generating device 200 is provided with a receiving chamber 201 and includes a heating component 204. The distal lip of the aerosol generating product 100 is located in the receiving chamber 201, and the medium section 10 generates aerosol under the heating action of the heating component 204.
[0122] It should be noted that when the aerosol generation system adopts the aerosol generation article 100 of any embodiment of this application, the aerosol generation system has all the advantages of the aerosol generation article 100 of that embodiment, which will not be repeated here.
[0123] In some embodiments, please refer to Figures 6 to 8The aerosol generating device 200 is also provided with an inner cavity 203, which is located on the periphery of the receiving chamber 201 and communicates with the periphery of the receiving chamber 201. One end of the air inlet 100c is connected to the inner cavity 203.
[0124] Here, air inlet 100c refers to the first air inlet 100d and the second air inlet 10a. That is, when the aerosol generating product 100 is provided with the first air inlet 100d, one end of the first air inlet 100d is connected to the inner cavity 203; when the aerosol generating product 100 is provided with the first air inlet 100d and the second air inlet 10a, both the first air inlet 100d and the second air inlet 10a are connected to the inner cavity 203.
[0125] It should be noted that the inner cavity 203 can be understood as being formed by slotting on the side wall of the receiving chamber 201. The inner cavity 203 extends circumferentially along the receiving chamber 201. After the aerosol generating article 100 is inserted into the receiving chamber 201, the inner cavity 203 surrounds the periphery of the aerosol generating article 100.
[0126] The inner cavity 203 is connected to the outside through the opening of the receiving chamber 201. The inner cavity 203 can store a certain amount of air. By setting the inner cavity 203, air can easily enter the aerosol generating product 100 through the air inlet 100c during the aerosol extraction process.
[0127] In some embodiments, please refer to Figure 6 and Figure 7 The inner cavity 203 extends circumferentially along the receiving chamber 201 and is connected end to end.
[0128] That is, the inner cavity 203 extends circumferentially around the receiving chamber 201.
[0129] In this embodiment, the air inlet 100c can communicate with the inner cavity 203 regardless of the angle at which the aerosol generating product 100 is inserted into the receiving chamber 201 along its circumference, thereby facilitating the entry of the air inlet 100c into the cavity within the inner cavity 203.
[0130] In some embodiments, please refer to Figure 8 The inner cavity 203 extends circumferentially along the receiving chamber 201 and is not connected end to end. The aerosol generating product 100 can rotate within the receiving chamber 201 along its axis, and the aerosol generating product 100 can rotate to a position where one end of the air inlet 100c communicates with the inner cavity 203.
[0131] That is, the angle at which the inner cavity 203 extends circumferentially along the receiving chamber 201 is less than 360°.
[0132] In this embodiment, by rotating the aerosol generating product 100, the air inlet 100c can be connected to or disconnected from the inner cavity 203. In this way, the user can adjust the air intake of the aerosol generating product 100 according to the actual suction situation.
[0133] In some embodiments, please refer to Figure 9 The aerosol generating device 200 is provided with a flow channel 202, one end of which is connected to the atmosphere and the other end of which penetrates the side wall of the receiving chamber 201; the aerosol generating product 100 can rotate within the receiving chamber 201 along its axis, and the aerosol generating product 100 can rotate to a position where one end of the air inlet 100c is connected to one end of the flow channel 202.
[0134] Here, the other end of the guide channel 202 can penetrate the outer wall of the aerosol generating device 200, allowing air to flow directly from one end of the guide channel 202 to the other. Air from the external environment enters the air inlet 100c directly through the guide channel 202 and then enters the interior of the aerosol generating product 100 through the air inlet 100c. That is, it does not rely on the opening of the receiving chamber 201 for air intake, thus improving the smoothness of air intake through the air inlet 100c.
[0135] In this embodiment, the air inlet 100c can be connected to or disconnected from the guide channel 202 by rotating the aerosol generating product 100. In this way, the user can adjust the air intake of the aerosol generating product 100 according to the actual suction situation.
