[0030] The embodiments of this application first provide an aerosol generating article for use in heated non-combustible appliances, see reference. Figure 1 The aerosol generating product 1 includes a carrier 11 and an aerosol generating matrix 12, which are stacked together with the carrier 11.

[0031] The support 11 specifically refers to the structure used to support the aerosol generating matrix 12, thereby providing structural strength for the aerosol generating article 1. The specific structural form of the support 11 is not limited. As an example, the support 11 can be configured as a sheet structure, and the aerosol generating matrix 12 can be disposed on one or both outer surfaces of the support 11 along its thickness direction. As another example, the support 11 can be configured as a columnar structure, and the aerosol generating matrix 12 can be disposed on the circumferential outer surface of the support 11.

[0032] The specific material of the support body 11 is not limited. As an example, the support body 11 can be made of metal, thus giving it high structural strength and good thermal conductivity. Of course, the support body 11 can also be made of plastic, ceramic, etc., as long as it has the desired structural strength and can withstand the heating temperature of the heated non-combustible appliance 2.

[0033] The specific composition of the aerosol generating matrix 12 is not limited, as long as it can generate aerosols when heated.

[0034] The specific method of fixing the aerosol generating matrix 12 and the carrier 11 is not limited. As an example, the aerosol generating matrix 12 can be fixed to the carrier 11 by a colloid, the specific composition of which is not limited. Alternatively, the aerosol generating matrix 12 and the carrier 11 can be fixed together by co-extrusion or other methods.

[0035] In the aerosol generating product of this application embodiment, the aerosol generating matrix 12 is disposed on the carrier 11, thereby allowing the user to insert the aerosol generating product 1 into the heated non-combustible appliance 2 for use according to actual needs, realizing the reuse of the heated non-combustible appliance 2 and increasing the number of suction ports of a single heated non-combustible appliance 2. In addition, the aerosol generating matrix 12 is disposed on the outer surface of the carrier 11, so that the aerosol generating matrix 12 can have a large contact area with the heating structure of the heated non-combustible appliance 2 during actual use, which helps the aerosol generating matrix 12 to be heated evenly, thereby improving the matrix utilization rate and thus increasing the number of suction ports of a single aerosol generating product.

[0036] In some embodiments, the aerosol generating matrix 12 is configured as a porous structure.

[0037] The aerosol generating matrix 12 is configured as a porous structure, specifically meaning that the aerosol generating matrix 12 is configured as a structure with multiple micropores. Here, micropores specifically refer to pores at the micrometer level. The specific number, pore size and distribution mode of the pores (such as ordered distribution or disordered distribution) are not limited.

[0038] As an example, the aerosol generating matrix 12 may include a framework component prepared from a porous material, thereby forming the aerosol generating matrix 12 into a structure with multiple micropores. Here, the porous material may be a natural porous material, a material obtained by artificially processing a natural porous material, or a synthetically produced porous material. In some embodiments, the porous material includes, but is not limited to, cellulose, microcrystalline cellulose, etc.

[0039] In some embodiments, the porosity of the aerosol generating matrix 12 is 50%-70%, such as any value among 50%, 52%, 54%, 56%, 58%, 60%, 62%, 64%, 68%, 70%, or any value between both. Here, porosity specifically refers to the volume percentage of pores in a single aerosol generating matrix 12.

[0040] In some embodiments, the pore size of the aerosol generating matrix 12 ranges from 50 to 300 μm, and more specifically, from 100 to 200 μm.

[0041] In this embodiment, the aerosol generating matrix 12 is configured with a porous structure, providing a large contact area between the aerosol generating matrix 12 and the airflow. This improves matrix utilization, thereby enhancing suction. Furthermore, the aerosol generating matrix 12 can release aerosols more stably and uniformly, improving the uniformity of taste and concentration in each suction.

[0042] In some embodiments, refer to Figure 1 The carrier 11 has multiple vent holes 11a, which penetrate the carrier 11 along the distribution direction of the carrier 11 and the aerosol generating matrix 12.

[0043] Taking the carrier 11 as a sheet structure as an example, the distribution direction of the carrier 11 and the aerosol generating matrix 12 is the thickness direction of the carrier 11, and the air pores 11a penetrate the carrier 11 along the thickness direction of the carrier 11.

[0044] Taking the carrier 11 as a columnar structure as an example, the distribution direction of the carrier 11 and the aerosol generating matrix 12 is the radial direction of the carrier 11, and the vent holes 11a penetrate the carrier 11 along the radial direction of the carrier 11. In this embodiment, the extension directions of the multiple vent holes 11a can be the same or different.

[0045] The aforementioned venting holes 11a can be formed on the carrier 11 by means such as laser etching, or the carrier 11 can be made of a porous material, thereby forming the aforementioned venting holes 11a on the carrier 11.

[0046] As mentioned above, in some embodiments, the aerosol generating matrix 12 is configured as a porous structure. It can be understood that the pores on the aerosol generating matrix 12 are microstructures, while the pores 11a on the carrier 11 are macrostructures.

[0047] The specific shape of the vent 11a is not limited. For example, the cross-sectional shape of the vent 11a can be circular, rectangular, triangular, irregular, etc.

[0048] In some embodiments, the hydraulic diameter of the vent 11a (the ratio of four times the cross-sectional area of ​​the flow passage to the wetted perimeter) is 0.5-1 mm, such as any value among 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, or any value between two of them.

[0049] In some embodiments, the ratio between the hydraulic diameter of the vent 11a and the pore diameter (e.g., the average pore diameter or the maximum pore diameter) of the aerosol generating matrix 12 is 2.5-10. It can be any value from 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, or any value between both.

[0050] The specific number and distribution of the vent holes 11a are not limited. The vent holes 11a can be distributed in an ordered manner or in a disordered manner.

[0051] In embodiments where the aerosol generating matrix 12 is configured as a porous structure, in the orthographic projection along the distribution direction of the aerosol generating matrix 12 and the carrier 11, the projections of at least some of the vent holes 11a can overlap with the projection of the aerosol generating matrix 12, thereby allowing at least some of the vent holes 11a to communicate with the pores of the aerosol generating matrix 12. And / or, the projections of at least some of the vent holes 11a can be offset from the projection of the aerosol generating matrix 12, thereby allowing at least some of the vent holes 11a to communicate with both sides of the carrier 11, thus improving airflow.

[0052] In some embodiments, the vent holes 11a may be arranged in an array, such as a rectangular array, a ring array, etc.

[0053] In some embodiments, the vent holes 11a are evenly distributed on the outer surface of the carrier 11.

[0054] In this embodiment, by providing vent holes 11a in the carrier 11, it is helpful to ensure that the aerosol generating matrix 12 is in full contact with the airflow (if the vent holes 11a are not provided, the surface of the aerosol generating matrix 12 facing the carrier 11 may not be able to make full contact with the airflow), thereby further increasing the contact area between the aerosol generating matrix 12 and the airflow, and thus improving the matrix utilization rate.

[0055] Of course, in some other embodiments, the carrier 11 may not be provided with the above-mentioned vent holes 11a.

[0056] In some embodiments, refer to Figure 1 The carrier 11 is configured as a sheet structure, and the aerosol generating matrix 12 is disposed on at least one side surface of the carrier 11 along the thickness direction.

[0057] Here, the carrier 11 may have an aerosol generating matrix 12 on only one side of its thickness direction, or it may have an aerosol generating matrix 12 on both opposite sides; there is no limitation on this.

[0058] In related technologies, aerosol-generating products are usually designed as columnar structures and heated by peripheral or central heating during actual use. This heating method can easily lead to uneven heating of the aerosol-generating matrix, which in turn reduces the matrix utilization and release uniformity, affecting the number of puffs and the consistency of taste per puff.

[0059] In this embodiment, during actual use, the aerosol generating matrix 12 can be heated in a planar heating manner, which will help improve the heating uniformity of the aerosol generating matrix 12, thereby further improving the matrix utilization rate and further improving the consistency of taste and concentration of each inhalation.

[0060] In some embodiments, refer to Figure 1 Specifically, one side surface of the support 11 along the thickness direction is formed as a heat-conducting surface, and the aerosol generating matrix 12 is disposed on the other side surface of the support 11 along the thickness direction.

[0061] Here, the heat-conducting surface is specifically used to face the heating structure of the heating non-combustible appliance 2 during actual use, and the heat of the heating structure will be conducted to the aerosol generating matrix 12 via the carrier 11.

[0062] In this embodiment, the heat from the heating structure is transferred to the aerosol generating matrix 12 via the carrier rather than directly to the aerosol generating matrix 12. This will make the heat distribution more uniform, thereby making the heating of the aerosol generating matrix 12 more uniform and further improving the matrix utilization rate.

[0063] Of course, in some other embodiments, the aerosol generating matrix 12 can also be provided on both sides of the support body 11 along the thickness direction. In this embodiment, the heating non-combustible appliance 2 can be provided with two sets of heating structures, which are respectively provided on both sides of the support body 11 along the thickness direction.

[0064] In some other embodiments, the carrier 11 may also be configured to generate heat when energized, and the heating non-combustible appliance 2 is used to energize the carrier 11 so that the carrier 11 generates heat.

[0065] In some embodiments, refer to Figure 1 There are multiple aerosol generating matrices 12, and the multiple aerosol generating matrices 12 are distributed at least at intervals along a first direction, which is perpendicular to the distribution direction of the aerosol generating matrices 12 and the carrier 11.

[0066] Taking the support body 11 as a sheet structure as an example, the first direction can be any direction perpendicular to the thickness direction of the support body 11.

[0067] Taking the support body 11 as a columnar structure as an example, the first direction can be the axial direction of the support body 11.

[0068] The multiple aerosol generating matrices 12 are at least spaced apart along the first direction. Specifically, each aerosol generating matrix 12 can be spaced apart along the first direction, or only a portion of them can be spaced apart along the first direction, while the other portion can be spaced apart along other directions.

[0069] In this embodiment, multiple aerosol generating matrices 12 are spaced apart. During use, only a portion of the aerosol generating matrices 12 can be heated at a time. After this portion of the aerosol generating matrices 12 has been completely or substantially released, another portion of the aerosol generating matrices 12 is then heated. This further improves the matrix utilization rate and the consistency of taste and concentration for each puff. Furthermore, since the multiple aerosol generating matrices 12 are spaced apart rather than continuously distributed, thermal crosstalk between the multiple aerosol generating matrices 12 can be blocked to a certain extent, reducing the loss of another portion of the aerosol generating matrices 12 when one portion is heated, thereby further improving the consistency of taste and concentration for each puff.

[0070] In some embodiments, the carrier 11 has a sheet-like structure, and the aerosol generating article 1 includes a plurality of aerosol generating matrix groups spaced apart along a first direction, each aerosol generating matrix group including a plurality of aerosol generating matrices 12 spaced apart along a second direction.

[0071] In this embodiment, during the actual heating process, only one aerosol generating matrix group can be heated at a time. The multiple aerosol generating matrices 12 in the aerosol generating matrix group are spaced apart, which helps to further increase the contact area between each aerosol generating matrix 12 and the airflow, thereby further improving the matrix utilization rate.

[0072] Specifically, each aerosol generating matrix group includes two aerosol generating matrices 12 spaced apart along the second direction, and the aerosol generating product 1 includes 4-6 aerosol generating matrix groups, that is, the aerosol generating product 1 includes a total of 8-12 aerosol generating matrices 12.

[0073] Compared with aerosol generating articles 1 containing the same amount of aerosol generating matrix 12 in related technologies, the aerosol generating articles 1 with the above-described structure in the embodiments of this application can improve the suction capacity by 100%-200%.

[0074] Embodiments of this application also provide a heated non-combustible appliance 2, which is used to heat the aerosol-generating article 1 as described in any of the above embodiments, referring to... Figure 2The heated non-combustible appliance 2 includes a housing 21 and a heating element 22. The housing 21 has a receiving cavity 211, and a suction port 21a and a mounting port 21c communicating with the receiving cavity 211. The mounting port 21c is configured to allow the aerosol generating article 1 to pass through. The heating element 22 is disposed in the receiving cavity 211.

[0075] Here, the specific structural form of the housing 21 is not limited, as long as it can form the aforementioned receiving cavity 211, suction port 21a, air inlet 21b and mounting port 21c.

[0076] The receiving cavity 211 is specifically used to receive the aforementioned aerosol generating article 1. The specific shape of the receiving cavity 211 can be determined according to the specific shape of the aerosol generating article 1, and is not limited thereto. It is understood that in addition to receiving the aerosol generating article 1, the receiving cavity 211 also needs to provide space for gas flow. Therefore, the volume of the receiving cavity 211 is usually larger than the volume of the aerosol generating article 1. Therefore, in some embodiments, a limiting structure can be provided in the receiving cavity 211. The limiting structure is used to constrain the position of the aerosol generating article 1 in the receiving cavity 211, for example, to constrain the aerosol generating article 1 to a position close to or in contact with the heating element 22. The specific structural form of the limiting structure can be specifically determined by those skilled in the art according to the actual desired limiting effect, and will not be elaborated here.

[0077] The air inlet 21b and the suction port 21a are connected to the receiving cavity 211. In actual use, as the user inhales from the suction port 21a, air will enter the receiving cavity 211 through the air inlet 21b and flow toward the suction port 21a. The aerosol generating matrix 12 is heated and comes into contact with the airflow to generate aerosol.

[0078] The mounting port 21c is configured to allow the aerosol generating article 1 to pass through. In this way, the user can insert the aerosol generating article 1 into the receiving cavity 211 for use through the mounting port 21c, or pull out the aerosol generating article 1 that has been released from the receiving cavity 211 and replace it with another aerosol generating article 1.

[0079] The heating element 22 is disposed in the receiving cavity 211. The heating element 22 is used to heat the aerosol-generated product 1. The specific structural form of the heating element 22 is not limited.

[0080] Taking the carrier of the aerosol generating product 1 as a sheet structure as an example, the heating element 22 can be disposed on one or both sides of the carrier in the thickness direction. Taking the carrier of the aerosol generating product 1 as a columnar structure as an example, the heating element 22 can be disposed along the circumference of the carrier, or the carrier can have an insertion hole that penetrates the carrier axially, and the heating element 22 is disposed as a rod structure and passes through the insertion hole.

[0081] The heated non-combustible appliance 2 of this embodiment has all the advantages of the aerosol generating product 1 described in any of the above embodiments. At the same time, the heated non-combustible appliance 2 of this application embodiment is also provided with an installation port 21c that allows the aerosol generating product 1 to pass through. In this way, it is possible to replace the aerosol generating product 1 for heating, thereby further increasing the total number of times the heated non-combustible appliance 2 can be pumped and reducing the user's usage cost.

[0082] In some embodiments, specifically, the heating element 22 has a heating plane disposed toward the aerosol generating article 1.

[0083] As an example, the heating element 22 is configured as a sheet structure, with one surface along its own thickness direction being configured as a heating plane.

[0084] Taking the carrier 11 as a sheet structure, with an aerosol generating matrix 12 on one side of the carrier along the thickness direction and a heat-conducting surface on the other side, in actual use, the heating plane of the heating element 22 is in contact with the heat-conducting surface of the carrier.

[0085] Taking the carrier 11 as a sheet structure, with aerosol generating matrix 12 provided on both sides of the carrier along the thickness direction, the number of heating elements 22 can be multiple, respectively provided on both sides of the carrier along the thickness direction.

[0086] In this embodiment, the heating element 22 is configured to have a heating plane, which enables uniform heating of the sheet-like aerosol generating product 1, thereby helping to improve the utilization rate of the matrix and thus improve the suction.

[0087] In some embodiments, refer to Figure 2 There are multiple heating elements 22, and the multiple heating elements 22 are configured to heat independently.

[0088] Here, the configuration of multiple heating elements 22 to be able to heat independently specifically means that any one heating element 22 can heat even when the other heating elements 22 are not heated.

[0089] In this embodiment, by setting multiple heating elements 22 that can be heated independently, the aerosol generating matrix 12 in the aerosol generating product 1 can be heated in sections, thereby further improving the matrix utilization rate and further improving the consistency of taste and concentration of each puff.

[0090] As an example, the heating element 22 can be set one-to-one with the aerosol generating matrix 12 or aerosol generating matrix group of the aerosol generating article 1.

[0091] Of course, the correspondence between the heating element 22 and the aerosol generating matrix 12 is not limited to this. For example, one heating element 22 can also correspond to multiple aerosol generating matrix groups. Or, for example, the number of aerosol generating matrix 12 can be one, and the heating element 22 can correspond to one region of the aerosol generating matrix 12.

[0092] In some embodiments, refer to Figure 2 Multiple heating elements 22 are distributed along the first direction, and the suction port 21a and the air inlet 21b are located on opposite sides of the heating elements 22 along the second direction, with the first direction intersecting the second direction.

[0093] Taking the support component as a sheet structure as an example, both the first direction and the second direction are perpendicular to the thickness direction of the support component.

[0094] In this embodiment, multiple heating elements 22 are distributed along a first direction. That is, during zone heating, each heating zone is distributed along the first direction. The suction port 21a and the air inlet 21b are located on opposite sides of the heating elements 22 along a second direction. That is, the airflow in the receiving cavity 211 flows along the second direction. Since the first and second directions intersect, the airflow will not flow across each heating zone, which helps to reduce thermal crosstalk between heating zones and further improve the consistency of taste and concentration for each suction. In addition, this arrangement also helps to extend the contact time between the aerosol generating matrix 12 and the hot airflow (especially in the embodiment mentioned above where the aerosol generating matrix group includes multiple aerosol generating matrices 12 spaced apart along the second direction), thereby further improving the matrix utilization rate.

[0095] In some embodiments, refer to Figure 2 The heated non-combustible appliance 2 includes a sealing element 23, which is disposed at the mounting port 21c.

[0096] Here, the seal 23 is mainly used to achieve a seal between the aerosol generating product 1 and the mounting port 21c, thereby reducing the probability of aerosol leakage from the mounting port 21c. The specific structural form of the seal 23 is not limited, as long as it can achieve the seal between the above structures. As an example, the seal 23 is set as a sealing ring, which extends along the periphery of the mounting port 21c to form a ring-shaped closed structure.

[0097] In some embodiments, refer to Figure 2 The heated non-combustible appliance 2 includes a pusher 24 connected to the housing 21. The pusher 24 is disposed opposite to the mounting port 21c and is used to push the aerosol generating article 1 toward the mounting port 21c.

[0098] Here, the relative arrangement of the pusher 24 and the mounting port 21c specifically means that the pusher 24 and the mounting port 21c are projected onto the same projection plane along the distribution direction of the pusher 24 and the mounting port 21c, and the projection of the pusher 24 and the mounting port 21c at least partially overlap. As an example, the mounting port 21c is located on one side of the housing 21 along the first direction, and the pusher 24 is connected to the other side of the housing 21 along the first direction. In actual use, the user can insert the aerosol-generated product 1 into the receiving cavity 211 or pull it out of the receiving cavity 211 along the first direction.

[0099] Here, the specific structure of the pusher 24 is not limited, as long as it can push the aerosol generating product 1 toward the mounting port 21c. In this way, when it is necessary to disassemble the aerosol generating product 1, the user can operate the pusher 24 to push at least a part of the aerosol generating product 1 out of the receiving cavity 211 through the mounting port 21c, thereby improving the convenience of replacing the aerosol generating product 1.

[0100] As an example, the pusher 24 can be configured as a press-type pop-up structure, allowing the user to pop up and retract the aerosol-generating product 1 by pressing the end face of the aerosol-generating product 1 facing the mounting port 21c. Specifically, the pusher includes a spring and a ratchet. When the spring is compressed, the ratchet switches between a locked state and an unlocked state. In the locked state, the spring is compressed and accumulates elastic potential energy; in the unlocked state, the spring extends and releases elastic potential energy.

[0101] As another example, the pusher 24 may include a push block and a handle. The push block is disposed in the receiving cavity 211, and the handle extends out of the housing 21. The user can operate the handle to move the push block toward or away from the mounting port 21c, thereby pushing out the aerosol-generated article 1.

[0102] Of course, in some other embodiments, the heating non-combustible appliance 2 may not include the pusher 24. In this embodiment, the aerosol generating product 1 may be configured such that after being inserted into the receiving cavity 211, a portion of it still extends out of the receiving cavity 211 from the mounting port 21c. The user can hold this portion and pull the aerosol generating product 1 out of the receiving cavity 211.

[0103] Embodiments of this application also provide an aerosol generation system, which includes an aerosol generation article 1 as described in any of the above embodiments, and a heated non-combustible appliance 2 as described in any of the above embodiments.

[0104] The aerosol generation system of this application embodiment has all the advantages of the aerosol generation article 1 and the heated non-combustible appliance 2 as described in any of the above embodiments, and will not be repeated here.

[0105] The following will provide a more detailed and specific description of the aerosol generating product 1, the heated non-combustible appliance 2, and the aerosol generating system mentioned above, using a specific embodiment as an example.

[0106] Reference Figure 1 and Figure 2 The aerosol generation system includes an aerosol generation product 1 and a heated non-combustible appliance 2.

[0107] The aerosol generating article 1 includes a carrier and an aerosol generating matrix 12 disposed on the outer surface of the carrier. The aerosol generating matrix 12 has a porous structure.

[0108] The carrier is a sheet-like structure. One surface of the carrier sheet along its thickness direction is set as a heat-conducting surface, and the other surface is provided with 4-6 aerosol generating matrix groups distributed along a first direction. Each aerosol generating matrix group includes two aerosol generating matrices 12 distributed along a second direction. The first direction, the second direction, and the thickness direction of the carrier are perpendicular to each other. The carrier sheet has multiple vent holes 11a penetrating the carrier sheet along its thickness direction, and the multiple vent holes 11a are evenly distributed on the surface of the carrier sheet along its thickness direction.

[0109] The heated non-combustible appliance 2 includes a housing 21 and a heating element 22 disposed within the housing 21. The housing 21 has a receiving cavity 211. An installation port 21c is formed on one side of the housing 21 along a first direction. An air inlet 21b and a suction port 21a are formed at opposite ends of the housing 21 along a second direction, respectively. The installation port 21c, the air inlet 21b, and the suction port 21a are all connected to the receiving cavity 211.

[0110] The heated non-combustible appliance 2 includes multiple heating elements 22 that are arranged one-to-one with the aerosol generating matrix group. The multiple heating elements 22 are distributed along a first direction and are configured to generate heat independently. In actual use, the multiple heating elements 22 generate heat sequentially.

[0111] The heating element 22 has a heating plane facing the aerosol generating article 1. In the same projection plane perpendicular to the thickness direction of the carrier, the projection of each heating plane covers the projection of two aerosol generating matrices 12 in an aerosol generating matrix group. When the aerosol generating article 1 is inserted into the receiving cavity 211, the heating plane is in contact with the heat-conducting surface of the carrier. There is a certain gap between the surface of the aerosol generating matrix 12 and the shell 21 to allow airflow.

[0112] In this embodiment of the application, each aerosol generating product 1 is drawn 20-40 times. Considering factors such as appliance wear and tear, each heated non-combustible appliance 2 can replace 10-15 pieces of aerosol generating product 1. Thus, the total number of draws for the heated non-combustible appliance 2 can reach 200-600 times.
