In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0037] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0038] As Figures 1 to 9 shown, the aerosol-generating article 100 includes: a housing 10 having a receiving cavity for receiving a solid aerosol matrix and an aerosol outlet 102 communicating with the receiving cavity, the receiving cavity having a plurality of heating zones 101; and heating elements 30, each heating zone 101 being respectively provided with a heating element 30 in thermal contact with the aerosol matrix, and the heating elements 30 of each heating zone 101 being capable of heating separately to heat the aerosol matrix in thermal contact therewith to generate an aerosol.

[0039] In the embodiment of the present application, since the housing 10 has a receiving cavity for receiving a solid aerosol matrix and an aerosol outlet 102 communicating with the receiving cavity, a solid aerosol matrix can be placed in the housing 10. Once the aerosol matrix is heated to generate an aerosol, the aerosol can flow out of the housing 10 through the aerosol outlet 102. Since the receiving cavity has a plurality of heating regions 101, and each heating region 101 is respectively provided with a heating element 30 in thermal contact with the aerosol matrix, and the heating element 30 in each heating region 101 can generate heat independently. Therefore, once the solid aerosol matrix is placed in the housing 10, there is aerosol matrix in each heating region 101, so that the heating element in each heating region 101 can generate heat independently, and further the heating elements in different heating regions 101 can generate heat, so that the aerosol matrix in different heating regions 101 is heated. That is to say, in the embodiment of the present application, by providing a plurality of heating regions 101 in the housing 10, each heating region 101 is respectively provided with a heating element 30 in thermal contact with the aerosol matrix, and the heating element 30 in each heating region 101 can generate heat independently. Thus, once the solid aerosol matrix is placed in the housing 10, the heating elements in the plurality of heating regions 101 can generate heat independently, which is equivalent to heating the aerosol matrix in different regions of the housing 10. Furthermore, the heating elements in the plurality of heating regions 101 can be made to generate heat in sequence according to actual needs, so that the heating duration of the aerosol matrix in the plurality of heating regions 101 is short, avoiding the problem that the aerosol matrix in the housing 10 is heated for too long to produce a burnt smell, which affects the overall sensory experience of the aerosol generating article 100 and results in a poor user experience. That is, in the embodiment of the present application, the generation of a burnt smell in the aerosol generating article 100 can be effectively avoided, and the user experience of the aerosol generating article 100 can be improved.

[0040] In the related art, the aerosol generating article 100 has a housing 10 with a receiving cavity for containing an aerosol matrix, and a heating element 30 is disposed in the receiving cavity. After the aerosol matrix is placed in the receiving cavity, the heating element heats the aerosol matrix in the receiving cavity. However, as the duration of the user using the aerosol generating article 100 increases, the heating element heats the aerosol matrix in the receiving cavity for a relatively long time, resulting in the aerosol matrix being prone to produce a burnt smell, which affects the user experience. In the embodiments of the present application, by providing a plurality of heating regions 101 in the housing 10, each heating region 101 is respectively provided with a heating element 30 in thermal contact with the aerosol matrix, and the heating element 30 in each heating region 101 can heat independently. Thus, once a solid aerosol matrix is placed in the housing 10, there is aerosol matrix in each heating region 101, which can make the heating elements in the plurality of heating regions 101 heat independently, equivalent to heating the aerosol matrix in different regions of the housing 10. Therefore, during the process of the user using the aerosol generating article 100, the heating elements in the plurality of heating regions 101 can heat sequentially, and then the aerosol matrix in each heating region 101 is heated sequentially to generate aerosol, effectively avoiding the burnt smell caused by heating all the aerosol matrix in the housing 10 for a relatively long time, thereby effectively improving the user experience of using the aerosol generating article 100.

[0041] In addition, in the embodiments of the present application, the number of the heating regions 101 can be set according to actual needs. For example, the number of the heating regions 101 is 3, and when the user uses the aerosol generating article 100, the aerosol matrix in each heating region 101 can be sucked by the user for 5 puffs; for another example, the number of the heating regions 101 is 15, and when the user uses the aerosol generating article 100, the aerosol matrix in each heating region 101 can be sucked by the user for 1 puff. The specific number of the heating regions 101 is not limited in the embodiments of the present application.

[0042] In addition, in the embodiments of the present application, the number of heating elements in each heating region 101 can be set according to actual needs. For example, the number of heating elements in each heating region 101 is 1, and for another example, the number of heating elements in each heating region 101 is multiple. At this time, the multiple heating elements in each heating region 101 can heat simultaneously. Of course, the multiple heating elements in each heating region 101 can also heat independently. The specific number of heating elements in each heating region 101 is not limited in the embodiments of the present application. Among them, in the embodiments of the present application, "multiple" means greater than or equal to 2.

[0043] In addition, in the embodiments of the present application, the aerosol matrix is tobacco or non-tobacco plants; and / or, the aerosol matrix is one or more of granular, filamentous, powdery, porous gel-like, and debris; and / or, the filling density range of the aerosol matrix is 0.4 g / cm2 -0.6g / cm 2 .

[0044] The filling density of the aerosol matrix refers to the filling density of the aerosol matrix filled in the heating area 101. By setting the filling density of the aerosol matrix to a range of 0.4 g / cm 2 -0.6g / cm 2 , which can ensure that the aerosol matrix in each heating area 101 has good looseness, so that the aerosol generated after the aerosol matrix in each heating area 101 is heated can flow smoothly to the corresponding heating area 101.

[0045] It should be noted that in the embodiment of the present application, the filling density of the aerosol matrix in each heating area 101 can be 0.4 g / cm 2 -0.6g / cm 2 For example, the packing density of the aerosol matrix in each heating area 101 is 0.4 g / cm 2 For another example, the filling density of the aerosol matrix in each heating area 101 is 0.5 g / cm 2 The filling density of the aerosol matrix in each heating area 101 is 0.6 g / cm 2 .

[0046] In addition, in some embodiments, Figure 2 As shown, the heating element 30 includes a connected heating body 31 and a heating electrode 32 , the heating body 31 is in thermal contact with the aerosol matrix in the heating area 101 where it is located, and at least a portion of the heating electrode 32 is exposed to the outside of the heating area 101 .

[0047] Since the heating body 31 is connected to the heating electrode 32, when the heating element 30 is arranged in each heating area 101, the heating body 31 can be in thermal contact with the aerosol matrix in the heating area 101 where it is located, so that the heating body 31 heats the aerosol matrix in the heating area 101 where it is located, and the heating electrode 32 transfers electrical energy to the heating body 31, so that the heating body 31 is heated. Since at least part of the heating electrode 32 is exposed to the outside of the heating area 101, in actual application, that is, the aerosol generating article 100 is applied to the heat-not-burn device, it can be convenient to contact the heating electrode 32 in the heat-not-burn device, so as to facilitate the connection of the heating electrode 32 to the electricity, so that the heating body 31 heats the aerosol matrix in the heating area 101 where it is located.

[0048] It should be noted that in the embodiments of the present application, the form of the heating electrode 32 can be a contact. Of course, the form of the heating electrode 32 can also be other forms. For example, the form of the heating electrode 32 can be an electrode rod. The specific form of the heating electrode 32 is not limited in the embodiments of the present application.

[0049] In addition, in the embodiments of the present application, the heating body 31 can be a spiral heating wire, a heating sheet or a heating film. Among them, when the heating body 31 is a spiral heating wire, the heating body 31 can be formed of a semiconductor material and can instantaneously heat up at high temperature after being energized. For example, the heating body 31 is formed of a semiconductor material such as lead-antimony alloy or lead-tin alloy into a spiral resistance wire to form a heating wire, and can heat up at high temperature within 0.2 seconds to 0.5 seconds after the heating body 31 is energized. When the heating body 31 is a heating sheet, the heating sheet can also be formed of a semiconductor material. When the heating body 31 is a heating film, the heating body 31 can be an FPC type heating body with a polyimide film or a polyester film as an insulating layer. At this time, once the heating body 31 is energized, the heating body 31 can quickly heat up.

[0050] In addition, in some embodiments, as Figure 1 shown, the housing 10 further has an air inlet 103; the air inlet 103 and the aerosol outlet 102 are respectively arranged on the opposite bottom wall and top wall of the housing 10. Through such a setting, during the process of the user using the aerosol generating article 100, air can enter the housing 10 through the air inlet 103, which is equivalent to mixing oxygen into the housing 10, so as to facilitate the aerosol matrix in the housing 10 to be heated to form an aerosol.

[0051] It should be noted that the air inlet 103 can be arranged on the bottom wall of the housing 10, and the aerosol outlet 102 can be arranged on the top wall of the housing 10. In addition, the number of the air inlets 103 can be set according to actual needs. For example, the number of the air inlets 103 is 1. For another example, the shape of the air inlet 103 is 2. The specific number of the air inlets 103 is not limited in the embodiments of the present application. In addition, the shape of the air inlet 103 can be set according to actual needs. For example, the shape of the air inlet 103 is circular. For another example, the shape of the air inlet 103 is oval. For another example, the shape of the air inlet 103 is square. The specific shape of the air inlet 103 is not limited in the embodiments of the present application.

[0052] In addition, in some embodiments, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the heating element 30 extends along the transverse direction X, the extending direction of the heating element 30 is perpendicular to the air outlet direction of the housing 10, and the two heating electrodes 32 of each heating element 30 are respectively located on one side or both sides of the housing 10.

[0053] When the heating element 30 extends along the transverse direction X, it is equivalent to arranging the heating element 30 in the transverse direction X. At this time, the extending direction of the heating element 30 is perpendicular to the air outlet direction of the housing 10. In addition, when the heating element 30 is U-shaped, at this time, the two heating electrodes 32 connected to both ends of the heating element 30 can be located on one side of the housing 10, that is, when the heating element 30 extends along the transverse direction X, the heating body 31 of the heating element 30 extends along the transverse direction X, and the two heating electrodes 32 connected to both ends of the heating body 31 are located on one side of the housing 10; when the heating element 30 is linear, at this time, the two electrodes connected to both ends of the heating element 30 can be respectively located on both sides of the housing 10, that is, when the heating element 30 extends along the transverse direction X, the heating body 31 of the heating element 30 extends along the transverse direction X, and one of the two heating electrodes 32 connected to both ends of the heating body 31 is located on one side of the housing 10, and the other heating electrode 32 is located on the other side of the housing 10.

[0054] It should be noted that the shape of the heating body 31 of the heating element 30 can be set according to actual needs, as long as it is ensured that the heating body 31 extends along the transverse direction X. For example, the heating body 31 is integrally wavy, and the heating body 31 extends along the transverse direction X as a whole.

[0055] In addition, when the air inlet 103 is located on the bottom wall of the housing 10 and the aerosol outlet 102 is located on the top wall of the housing 10, when the heating element 30 extends in the transverse direction X, the extending direction of the heating element 30 is perpendicular to the direction of the air flow in the housing 10, and the direction of the air flow in the housing 10 is the direction from the air inlet 103 to the aerosol outlet 102.

[0056] In addition, in some embodiments, such as Figure 7 、 Figure 8 and Figure 9 shown, the heating element 30 extends along the longitudinal direction Y, the extending direction of the heating element 30 is parallel to the air outlet direction of the housing 10, and the two heating electrodes 32 of each heating element 30 are both located on the air inlet side of the housing 10.

[0057] When the heating element 30 extends along the longitudinal direction Y, it is equivalent to arranging the heating element 30 in the longitudinal direction Y. At this time, the extending direction of the heating element 30 is parallel to the air outlet direction of the housing 10. In addition, when the heating element 30 is U-shaped, at this time, the two heating electrodes 32 connected to both ends of the heating element 30 can be located on one side of the housing 10, that is, on the air inlet side of the housing 10. When the heating element 30 extends along the longitudinal direction Y, the heating body 31 of the heating element 30 extends along the longitudinal direction Y, and the two heating electrodes 32 connected to both ends of the heating body 31 are located on the air inlet side of the housing 10.

[0058] It should be noted that the shape of the heating body 31 of the heating element 30 can be set according to actual needs, as long as it is ensured that the heating body 31 extends along the longitudinal direction Y. For example, the heating body 31 is integrally wavy, the heating body 31 extends along the longitudinal direction Y as a whole, and the two heating electrodes 32 connected to the heating body 31 are located on the same side.

[0059] In addition, when the air inlet 103 is located on the bottom wall of the housing 10 and the aerosol outlet 102 is located on the top wall of the housing 10, when the heating element 30 extends in the longitudinal direction Y, the extending direction of the heating element 30 is parallel to the direction of the air flow in the housing 10, and the direction of the air flow in the housing 10 is the direction from the air inlet 103 to the aerosol outlet 102. In addition, when the heating element 30 extends in the longitudinal direction Y, at least one aerosol outlet 102 is provided on a part of the top wall of the housing 10 corresponding to each heating area 101, and at least one air inlet 103 is provided on a part of the bottom wall of the housing 10 corresponding to each heating area 101.

[0060] In addition, in some embodiments, as Figure 6 shown, a barrier member 20 is provided in the housing 10, and the barrier member 20 is provided between two adjacent heating areas 101 to separate the aerosol matrices of the respective heating areas 101.

[0061] Since the barrier member 20 is provided in the housing 10, therefore, the barrier member 20 can be provided between two adjacent heating areas 101, so that the two adjacent heating areas 101 are separated by the barrier member 20, and the aerosol matrices in the two adjacent heating areas 101 are separated by the barrier member 20, ensuring that when the heating element in each heating area 101 heats the aerosol matrix in its corresponding heating area 101, only the aerosol matrix in the heating area 101 where the heating element is located is heated, and avoiding the problem that the aerosol matrices in the two adjacent heating areas 101 may be heated simultaneously due to the mixing of the aerosol matrices in the two adjacent heating areas 101. That is, by providing the barrier member 20 in the housing 10, it can be effectively ensured that when the aerosol matrix in each heating area 101 is heated, less influence is exerted on the aerosol matrix in the adjacent heating area 101.

[0062] It should be noted that in the embodiments of the present application, the barrier member 20 can be a partition board. Of course, the barrier member 20 can also be other components with a barrier function. For example, the barrier member 20 is a diaphragm. The specific form of the barrier member 20 is not limited in the embodiments of the present application.

[0063] In addition, in some embodiments, as Figure 1As shown, a plurality of through holes 201 are provided on each barrier member 20 at intervals, and the through holes 201 communicate with two adjacent heating regions 101, so that the aerosol generated in two adjacent heating regions 101 flows to the aerosol outlet 102.

[0064] Since a plurality of through holes 201 are provided on each barrier member 20 at intervals, and the barrier member 20 is arranged between two adjacent heating regions 101, two adjacent heating regions 101 can be communicated by the through holes 201 on the barrier member 20, so that the aerosol generated in one of the two adjacent heating regions 101 flows to the other heating region 101. Furthermore, the aerosol can flow in the housing 10 until it flows to the aerosol outlet 102 and flows out from the aerosol outlet 102. That is, by providing a plurality of through holes 201 on each barrier member 20, it can be effectively ensured that the aerosol generated in each heating region 101 can flow to the aerosol outlet 102.

[0065] It should be noted that the number of through holes 201 on each barrier member 20 can be set according to actual needs. For example, the number of through holes 201 on each barrier member 20 is 3, or for another example, the number of through holes 201 on each barrier member 20 is 5. The number of through holes 201 on each barrier member 20 is not limited in the embodiments of the present application. In addition, the through hole 201 can be a hole with a relatively large size. Of course, the through hole 201 can also be a hole formed by a plurality of small holes.

[0066] In addition, in the embodiments of the present application, as Figure 1 shown, when the barrier member 20 extends along the transverse direction X and the heating member extends along the transverse direction X, a plurality of through holes 201 can be provided on the barrier member 20, so that two adjacent heating regions 101 are communicated by the through holes 201 on the barrier member 20, ensuring that the aerosol generated in each heating region 101 can flow to the aerosol outlet 102. As Figure 7 shown, when the barrier member 20 extends along the longitudinal direction Y and the heating member extends along the longitudinal direction Y, a plurality of through holes 201 can be provided on the barrier member 20, or a plurality of through holes 201 may not be provided on the barrier member 20.

[0067] In addition, in some embodiments, as Figure 6 shown, a barrier member 20 and a breathable barrier net 40 are provided in the housing 10. The barrier member 20 extends along the transverse direction X, and the barrier net 40 intersects with the barrier member 20. One side of the barrier net 40 cooperates with the barrier member 20 and the housing 10 to define a plurality of accommodation spaces for the aerosol matrix; the other side of the barrier net 40 cooperates with the housing 10 to define an air flow channel 1011 communicating the air inlet 103 and the aerosol outlet 102.

[0068] Since the barrier member 20 extends along the transverse direction X and the barrier net 40 intersects the barrier member 20, after one side of the barrier net 40 cooperates with the barrier member 20 and the housing 10, a plurality of accommodation spaces for the aerosol matrix can be defined. Each accommodation space can accommodate the aerosol matrix, and adjacent two accommodation spaces are separated by the barrier member 20. The other side of the barrier net 40 cooperates with the housing 10, and an air flow channel 1011 communicating the air inlet 103 and the aerosol outlet 102 can be defined. After the aerosol matrix in each accommodation space is heated to generate aerosol, the aerosol enters the air flow channel 1011 through the barrier net 40 and flows from the air flow channel 1011 to the aerosol outlet 102. That is, by providing the barrier member 20 and the barrier net 40, it is convenient to form the accommodation space for the aerosol matrix and the air flow channel 1011 for the aerosol to flow.

[0069] In addition, when the barrier member 20 and the breathable barrier net 40 are provided in the housing 10, at this time, in the plurality of accommodation spaces defined by the cooperation of the barrier net 40 with the housing 10 and the barrier member 20, each accommodation space is provided with a heating element 30, and the length of the heating element 30 is close to the length of the accommodation space, and the length of the heating element 30 is close to the length of the accommodation space, so that the aerosol matrix in the accommodation space can be better heated to generate aerosol.

[0070] In addition, in some embodiments, the barrier net 40 has a plurality of mesh holes, and the aperture of the mesh holes is smaller than the particle size of the aerosol matrix. Through such a setting, the barrier net 40 can effectively block the aerosol matrix in the heating area 101, and avoid the problem that the aerosol matrix in the heating area 101 enters the air flow channel 1011 and affects the flow of the aerosol in the air flow channel 1011.

[0071] The embodiment of the present application provides a heat-not-burn system, as Figures 10 to 13 shown, the heat-not-burn system includes a heat-not-burn device and an aerosol generating article 100 in any one of the above embodiments. The heat-not-burn device includes a power supply component 01 and a power supply terminal 02. The power supply component 01 is used to be electrically connected to each heating element 30 through the power supply terminal 02 after the aerosol generating article 100 is loaded into the heat-not-burn device.

[0072] Wherein, the heating element 30 includes a heating main body 31 and a heating electrode 32. Once the aerosol generating article 100 is loaded into the heat-not-burn device, the heating electrode 32 of the heating element 30 contacts the power supply terminal 02, so that the power supply component 01 can supply power to the heating electrode 32 through the power supply terminal 02, and the heating electrode 32 transfers the electric energy to the heating main body 31, making the heating main body 31 generate heat.

[0073] It should be noted that the power supply component 01 is electrically connected to the power supply terminal 02, and the power supply component 01 can transfer electric energy to the power supply terminal 02.

[0074] In addition, in some embodiments, as Figure 10 shown, the heat-not-burn device includes a housing 200, an air switch 300, and a controller 400; the controller 400 and the air switch 300 are both located in the housing 200, the air switch 300 and each heating element 30 are electrically connected to the controller 400, and the air switch 300 is used to detect whether the user inhales the aerosol-generating article 100; when the air switch 300 detects that the user inhales the aerosol-generating article 100, the controller 400 controls the heating elements 30 in at least two different heating regions 101 to work alternately.

[0075] Among them, the housing 200 has a placement cavity for placing the aerosol-generating article 100. A power supply terminal 02 is provided on the cavity wall of the placement cavity. The power supply component 01 is located in the housing 200. Once the aerosol-generating article 100 is loaded into the placement cavity of the housing 200, the heating electrode 32 of the heating element 30 of the aerosol-generating article 100 contacts the power supply terminal 02.

[0076] In addition, when the user uses the heat-not-burn device, once the user inhales the aerosol-generating article 100, the air switch 300 can detect the user's inhalation, so that the air switch 300 transmits a signal to the controller 400. After receiving the signal, the controller 400 can control the power supply terminal 02 in contact with the heating element 30 in at least two different heating regions 101 to transfer electric energy to the heating electrode 32 in contact with it, so that the heating elements 30 in at least two different heating regions 101 work alternately, avoiding the aerosol matrix in each heating region 101 from being heated for too long and generating a burnt smell.

[0077] In addition, in the embodiments of the present application, the controller 400 is further configured to: when the air switch 300 detects that the user inhales the aerosol-generating article 100, control the heating elements 30 in multiple heating regions 101 to generate heat in sequence according to the arrangement order of the multiple heating regions 101. Through such a setting, it is equivalent that each heating region 101 in the aerosol-generating article 100 is heated, and the aerosol matrix in a single heating region 101 is prevented from being heated for a long time and generating a burnt smell.

[0078] In addition, in the embodiments of the present application, the controller 400 can also determine the number of times the user sucks the aerosol generating article 100 by controlling the switch. When the controller 400 determines that the number of times the user starts to suck the aerosol generating article 100 reaches the preset suction times, the controller 400 controls the heating element 30 in the heating area 101 adjacent to the heating area 101 where the currently heating heating element 30 is located to generate heat, and makes the currently heating heating element 30 stop generating heat. Through such a setting, it is possible to avoid the aerosol matrix in a single heating area 101 being heated for a long time to produce a burnt smell.

[0079] For example, the aerosol generating article 100 has 3 heating areas 101, and the preset suction times is 5 times. Once the aerosol generating article 100 is placed in the housing 200 of the heat-not-burn device, when the user uses the heat-not-burn device, the air switch 300 detects that the user sucks the aerosol generating article 100. Once the controller 400 determines through the air switch 300 that the user starts to suck the aerosol generating article 100, the controller 400 makes the heating element 30 in the first heating area 101 generate heat. After the controller 400 determines that the number of times the user sucks reaches 5 times, the controller 400 makes the heating element 30 in the second heating area 101 generate heat, and makes the heating element 30 in the first heating area 101 stop generating heat. When the controller 400 determines again that the number of times the user sucks reaches 5 times, the controller makes the heating element 30 in the third heating area 101 generate heat, and makes the heating element 30 in the second heating area 101 stop generating heat.

[0080] In addition, in the embodiments of the present application, the heating body 31 of the heating element 30 in each heating area 101 can be a heating wire, and the heating wire is made of lead-antimony alloy or lead-tin alloy, and the heating body 31 is fusible. Specifically, the fusing temperature of the heating wire made of lead-antimony alloy is 480 °C, and the fusing temperature of the heating wire made of lead-tin alloy is 90 - 240 °C. Through such a setting, the fusing of the heating wire can be realized. And the fusing time can be controlled by the thickness of the heating wire. For example, there are 3 heating areas 101, and each heating area 101 can provide 5 puffs of suction. After the user sucks 5 puffs, the heating wire in the first heating area 101 fuses. When the user sucks 5 puffs again, the heating wire in the second heating area 101 fuses. When the user sucks 5 puffs again, the heating wire in the third heating area 101 fuses.

[0081] In addition, in the embodiments of the present application, the heating body 31 of the heating element 30 in each heating area 101 is a heating wire, and the heating wire does not fuse, that is, the heating wire is made of a high-melting-point alloy and will not fuse after heating. At this time, the heating wire in different heating areas 101 can be heated by the power supply of the controller 400. For example, there are 3 heating areas 101, and each heating area 101 can provide 5 puffings. After the user takes 5 puffings, the heating wire in the first heating area 101 heats up. When the user takes another 5 puffings, the heating wire in the second heating area 101 heats up. When the user takes another 5 puffings, the heating wire in the third heating area 101 heats up.

[0082] In addition, in the embodiments of the present application, the heat-not-burn device includes an air inlet, a receiving cavity, and an air intake passage connecting the air inlet and the receiving cavity. Among them, the air inlet is located on the housing 200, and the receiving cavity and the air intake passage are located in the housing 200. Once the aerosol-generating article 100 is loaded into the receiving cavity of the housing 200, the air intake passage communicates with the air inlet 103 of the aerosol-generating article 100. When the user uses the heat-not-burn device, that is, when the user takes a puff, air can sequentially enter the outer shell 10 of the aerosol-generating article 100 from the air inlet and the air intake passage, so that air flows into the outer shell 10 of the aerosol-generating article 100. Furthermore, the aerosol matrix in the outer shell 10 of the aerosol-generating article 100 is heated to generate aerosol, and then the air and the aerosol are drawn out together.
