[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] See also Figure 1The embodiment of the present application provides an aerosol generating device, which includes a heating component 1000 and a power component. The heating component 1000 is used to accommodate an aerosol generating matrix 2000, and atomize the aerosol generating matrix 2000 to generate an aerosol when powered on. The power component is electrically connected to the heating component 1000 and is used to supply power to the heating component 1000.

[0039] The aerosol-generating matrix 2000 may be a solid matrix, for example, one or more of powders, particles, fragments, strips, or flakes of one or more plant leaves such as tobacco, herb leaves, tea leaves, and mint leaves; or, the solid matrix may contain additional volatile aroma compounds to be released when the matrix is ​​heated. Of course, the aerosol-generating matrix 2000 may also be a liquid matrix or a paste matrix, such as oils or liquid medicines with added aroma components.

[0040] In one embodiment, see Figure 2 The heating assembly 1000 includes a receiving component 100 for receiving an aerosol generating substrate 2000, the receiving component 100 is formed with a receiving cavity, and a supporting gas-cutting member 200 and a base 300 are arranged in the receiving cavity; in an optional embodiment, the receiving component 100 is provided with a heating member 110; in an optional embodiment, a portion of the receiving component 100 corresponding to the receiving cavity is at least partially provided with the heating member 110; or, in an optional embodiment, the receiving component 100 includes a supporting member (not shown in the figure) and a heating member 110, the receiving cavity has two ends, the base 300 is arranged at one end, and the supporting gas-cutting member 200 is arranged in the container cavity near the other end of the receiving cavity; at least one of the supporting gas-cutting member 200 and the base 300 is formed with a gas-cutting port.

[0041] Specifically, when the heating assembly 1000 is vertically arranged, the base 300 and the supporting gas-cutting member 200 are respectively arranged at the bottom and top of the accommodating cavity. The base 300 and the supporting gas-cutting member 200 are not only used to support the aerosol generating matrix 2000, but also can form an airflow channel and realize gas cutting.

[0042] After the aerosol generating substrate 2000 is inserted into the accommodating cavity, the accommodating component 100 is sleeved outside the aerosol generating substrate 2000, and a first gap 500 is formed between the accommodating component 100 and the aerosol generating substrate 2000. The heating element 110 heats the aerosol generating substrate 2000 to generate aerosol. At the same time, the external airflow enters the first gap 500 through the supporting air cut-off component 200, and enters the aerosol generating substrate 2000 from the distal lip end of the aerosol generating substrate 2000 through the base 300, thereby carrying the aerosol out for the user to inhale.

[0043] In the embodiment of the present application, the heating element 110 is provided through the accommodating component 100, so that when the aerosol generating substrate 2000 is inserted into the accommodating cavity, the airflow will flow between the accommodating component 100 provided with the heating element 110 and the aerosol generating substrate. On the one hand, the airflow can be intercepted by the accommodating component 100 to improve the airflow stability. On the other hand, the airflow can also be preheated before entering the aerosol generating substrate to improve the aerosol generating efficiency. At the same time, by providing an air interception port on at least one of the supporting air interception component 200 and the base 300, the airflow can be intercepted before and / or after flowing through the heating element 110, further improving the airflow stability and improving the inhalation taste of the aerosol generating device.

[0044] In one embodiment, see Figures 6 to 8 , a first air cut-off port 220 is formed on the support air cut-off member 200; a second air cut-off port 323 is formed on the base 300. The external airflow first passes through the first air cut-off port 220 for the first air cut-off, then passes through the first gap 500 for the second air cut-off, and finally passes through the third air cut-off port for the third air cut-off, thereby ensuring the stability of the airflow. It can be understood that in other embodiments of the present application, only the first air cut-off port 220 may be provided, and no air cut-off may be performed at the base 300; or, air cut-off may be performed only at the base 300, and no air cut-off may be performed at the support air cut-off member 200, which is not the only limitation here.

[0045] In one embodiment, the number of the first air cutoffs 220 ranges from 2 to 10; the opening cross-sectional area of ​​the first air cutoffs 220 ranges from 0.5 mm to 3.0 mm. Specifically, the number of the first air cutoffs 220 can be 2, 3, 4, 5, 6, 7, 8, 9 or 10, and the opening cross-sectional area of ​​the first air cutoffs 220 can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm. In this embodiment, the number range and the opening cross-sectional area range of the first air cutoffs 220 are limited so that the setting of the first air cutoffs 220 can achieve the purpose of flow limiting. That is, in the design process, the number of the first air cutoffs 220 can be adjusted according to actual needs, and the appropriate opening cross-sectional area can be matched to achieve the required flow rate, so that the airflow stability can be improved under the premise of ensuring smooth airflow. It is understandable that in other embodiments of the present application, the number of the first air cut-off openings 220 may be one or greater than ten, and the opening cross-sectional area of ​​the first air cut-off openings 220 may be greater than 3 mm, or even greater, so that the airflow is not blocked or restricted when passing through the supporting air cut-off member 200.

[0046] It should be noted that the opening cross-sectional area of ​​the first gas cut-off opening 220 refers to the cross-sectional area of ​​the first gas cut-off opening 220 along a radial surface parallel to the supporting gas cut-off member 200 .

[0047] In one embodiment, the number of the second air cut-off openings 323 ranges from 2 to 10; the opening cross-sectional area of ​​the second air cut-off openings 323 ranges from 0.5 mm to 3.0 mm. Specifically, the number of the second air cut-off openings 323 can be 2, 3, 4, 5, 6, 7, 8, 9 or 10, and the opening cross-sectional area of ​​the second air cut-off openings 323 can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm. In this embodiment, the number range and the opening cross-sectional area range of the second air cut-off openings 323 are limited so that the setting of the second air cut-off openings 323 can achieve the purpose of flow limiting. That is, in the design process, the number of the second air cut-off openings 323 can be adjusted according to actual needs, and the appropriate opening cross-sectional area can be matched to achieve the required flow rate, so that the airflow stability can be improved while ensuring smooth airflow. It is understandable that in other embodiments of the present application, the number of the second air cut-off openings 323 may be one or greater than ten, and the opening cross-sectional area of ​​the second air cut-off openings 323 may be greater than 3 mm, or even greater, so that the airflow is not blocked or restricted when passing through the supporting air cut-off member 200.

[0048] It should be noted that the opening cross-sectional area of ​​the second gas cut-off opening 323 refers to the cross-sectional area of ​​the second gas cut-off opening 323 along the circumferential surface parallel to the base 300 .

[0049] In one embodiment, the number of the first air cut-off openings 220 ranges from 2 to 10; the opening cross-sectional area of ​​the first air cut-off openings 220 ranges from 0.5 mm to 3.0 mm. The number of the second air cut-off openings 323 ranges from 2 to 10; the opening cross-sectional area of ​​the second air cut-off openings 323 ranges from 0.5 mm to 3.0 mm. By limiting the flow at two positions simultaneously, the airflow is regulated to improve the airflow stability.

[0050] In one embodiment, see Figure 7 and Figure 8 The first air cut-off opening 220 is formed by a concave arrangement on the inner circumference of the supporting air cut-off member 200. That is, the airflow passing through the first air cut-off opening 220 will directly contact the outer circumference of the aerosol generating substrate 2000. In other embodiments of the present application, the first air cut-off opening 220 may not be formed on the inner circumference of the supporting air cut-off member 200, but may be formed at a position between the inner circumference and the outer circumference of the supporting air cut-off member 200, which is not limited here.

[0051] In one embodiment, see Figure 7 and Figure 8 The first air cut-off port 220 is in a semicircular arc shape and has an arc-shaped surface, which is convenient for air flow.

[0052] In one embodiment, see Figure 2, the support gas-cutting member 200 is configured to be sleeved outside the aerosol generating matrix 2000; the inner circumferential surface of the support gas-cutting member 200 is configured to abut against the outer circumferential surface of the aerosol generating matrix 2000. The inner circumferential surface of the support gas-cutting member 200 refers to the inner side surface of the support gas-cutting member 200 along the circumferential direction. In this embodiment, the inner circumferential surface of the support gas-cutting member 200 is fitted and limited to the outer circumferential wall of the aerosol generating matrix 2000 in the circumferential direction, thereby ensuring the installation stability of the aerosol generating matrix 2000. It can be understood that in other embodiments of the present application, the support gas-cutting member 200 can also be composed of a plurality of limit blocks arranged outside the aerosol generating matrix 2000, which is not the only limitation here.

[0053] In one embodiment, see Figure 2 The supporting gas-cutting member 200 is set to be sleeved outside the aerosol generating matrix 2000; the inner circumference of the supporting gas-cutting member 200 is set to abut against the outer circumference of the aerosol generating matrix 2000; the supporting gas-cutting member 200 is coaxially arranged with the accommodating member 100. In this embodiment, the supporting gas-cutting member 200 and the accommodating member 100 are coaxially arranged, and the inner circumference of the supporting gas-cutting member 200 and the outer circumference of the aerosol generating matrix 2000 are arranged in contact with each other, so that after the aerosol generating matrix 2000 is inserted into the supporting gas-cutting member 200, the supporting gas-cutting member 200 and the aerosol generating matrix 2000 are also coaxially arranged, and thus the accommodating member 100 and the aerosol generating matrix 2000 are coaxially arranged. That is, by providing the supporting air-cutting member 200, the centrality of the aerosol generating substrate 2000 in the accommodating component 100 can be improved, so that the gap between the outer peripheral wall of the aerosol generating substrate 2000 and the inner peripheral wall of the accommodating component 100 is evenly distributed in the axial and circumferential directions of the aerosol generating substrate 2000, which not only ensures the airflow stability, but also makes the aerosol generating substrate 2000 heated evenly.

[0054] In one embodiment, see Figure 4 and Figure 8 The base 300 has a support surface 321 facing the support gas cut-off member 200, the support surface 321 is concave to form a groove 322, and the second gas cut-off opening 323 extends from the outer peripheral wall of the base 300 to the groove 322. When the aerosol generating substrate 2000 is inserted into the accommodating cavity, the distal lip end of the aerosol generating substrate 2000 abuts against the support surface 321 of the support gas cut-off member 200, and the airflow flowing to the bottom of the accommodating cavity enters the groove 322 through the second gas cut-off opening 323, and enters the aerosol generating substrate 2000 from the distal lip end of the aerosol generating substrate 2000.

[0055] In one embodiment, the supporting gas-cutting member 200 has a fitting surface 210, and the base 300 has a supporting surface 321; the fitting surface 210 is configured to fit and abut against the outer peripheral wall of the aerosol generating substrate 2000 to radially limit the aerosol generating substrate 2000; the supporting surface 321 is configured to abut against the axial end surface of the aerosol generating substrate 2000 to axially limit the aerosol generating substrate 2000.

[0056] It should be noted that the outer peripheral wall of the aerosol generating substrate 2000 refers to the outer side wall of the aerosol generating substrate 2000 along the circumferential direction. When the outer peripheral wall of the aerosol generating substrate 2000 is in contact with the fitting surface 210, the aerosol generating substrate 2000 cannot move in any radial direction, so that the aerosol generating substrate 2000 can be radially limited by the fitting surface 210.

[0057] In the embodiment, the aerosol generating substrate 2000 can be radially limited by the fitting surface 210, and the aerosol generating substrate 2000 can be axially limited by the supporting surface 321, so that when the aerosol generating substrate 2000 is inserted into the accommodating component 100, the aerosol generating substrate 2000 will not change position during the heating process, thereby improving the heating effect consistency of the aerosol generating substrate 2000 during the heating process, and improving the suction consistency of the aerosol generating substrate 2000. In addition, after the aerosol generating substrate 2000 is stabilized in the accommodating component 100, the gap between the aerosol generating substrate 2000 and the inner wall of the accommodating component 100 can also be kept consistent, which can improve the consistency of air intake from the bottom of the aerosol generating substrate 2000, thereby ensuring the suction effect consistency of the aerosol generating substrate 2000.

[0058] In one embodiment, see Figure 3 The aerosol generating substrate 2000 has a substrate segment 2100. The substrate segment 2100 stores an aerosol generating substrate, which is a solid substrate of plant leaves having a specific aroma and can generate aerosol under heating conditions; the form of the aerosol generating substrate is not limited to an ordered solid aerosol generating substrate, a disordered solid aerosol generating substrate, and a particle solid aerosol generating substrate. When the heating component 1000 is powered on, the aerosol generating substrate in the substrate segment 2100 of the aerosol generating substrate 2000 is heated and baked to generate aerosol.

[0059] In one embodiment, see Figure 3The aerosol generating substrate 2000 further includes a hollow section 2200, a cooling section 2300 and a filter section 2400. The hollow section 2200 and the cooling section 2300 are arranged between the substrate section 2100 and the filter section 2400, and the hollow section 2200 is located at one end of the cooling section 2300 close to the substrate section 2100. The aerosol generated by heating the aerosol generating substrate of the aerosol generating substrate 2000 gathers in the hollow section 2200, is cooled by the cooling section 2300, and finally flows through the filter section 2400 to be inhaled by the user.

[0060] It should be noted that the above-mentioned hollow section 2200 and cooling section 2300 are optional structures. The aerosol generating matrix 2000 has only the matrix section 2100 as a necessary structure, and the matrix section 2100 is used to generate aerosol for users to inhale. In other embodiments, the aerosol generating matrix 2000 may include a matrix section 2100 and a filter section 2400; or, the aerosol generating matrix 2000 may include a matrix section 2100, a hollow section 2200 and a filter section 2400; or, the aerosol generating matrix 2000 includes the matrix section 2100, the hollow section 2200, the cooling section 2300, and the filter section 2400, and also includes other structures that can improve the user experience.

[0061] In one embodiment, see Figure 2 The receiving component 100 provided with the heating element 110 is at least sheathed on the substrate segment 2100 of the aerosol generating substrate 2000 to heat the substrate segment 2100. The substrate segment 2100 of the aerosol generating substrate 2000 is completely sheathed by the receiving component 100 provided with the heating element 110, so that the substrate segment 2100 can be fully heated, ensuring that the substrate segment 2100 can generate aerosol sufficiently and stably.

[0062] In one embodiment, see Figure 2 The portion of the accommodating component 100 provided with the heating element 110 is sleeved on the substrate segment 2100 and the portion of the hollow segment 2200. The cooling segment 2300 and the filter segment 2400 of the aerosol generating substrate 2000 extend out of the accommodating component 100 to prevent the cooling effect of the cooling segment 2300 from being affected by the heat accumulation of the accommodating component 100.

[0063] In one embodiment, see Figure 2, the support gas cut-off member 200 and the base 300 are respectively located at the axial ends of the portion of the accommodating part 100 provided with the heating member 110. For the aerosol generating matrix 2000, its main heating portion is located at the matrix segment 2100, and the portion of the accommodating part 100 provided with the heating member 110 is also sleeved outside the matrix segment 2100. If the matrix segment 2100 is not stably installed in the portion of the accommodating part 100 provided with the heating member 110, it will cause the matrix segment 2100 to tilt in the accommodating part 100, which will cause some parts of the matrix segment 2100 to have too high a temperature, while other parts have too low a temperature, resulting in uneven heating, and at the same time, it will cause the gap between the matrix segment 2100 and the accommodating part 100 to be inconsistent, resulting in blockage of some positions and affecting the stability of the airflow. In this embodiment, by arranging the support and gas-cutting member 200 and the base 300 at the two axial ends of the accommodating member 100, the installation stability of the substrate segment 2100 corresponding to the accommodating member 100 is ensured, so that the gap between the substrate segment 2100 and the accommodating member 100 remains unchanged, so that the heating distribution of the substrate segment 2100 is uniform, and the airflow remains smooth, thereby ensuring the suction stability. It can be understood that in other embodiments of the present application, the support and gas-cutting member 200 and the base 300 can also be located at the same end of the accommodating member 100 where the heating member 110 is provided, for example, the support and gas-cutting member 200 and the base 300 are both arranged below the heating member 110, as long as the aerosol generating substrate 2000 can be positioned stably.

[0064] In one embodiment, see Figure 4 and Figure 5 The heating assembly 1000 further includes a positioning member 400; the positioning member 400 is detachably connected to the accommodating member 100; the positioning member 400 and the base 300 are respectively arranged at the axial ends of the portion of the accommodating member 100 provided with the heating member 110; the positioning member 400 and the base 300 are respectively used to axially and radially position the axial ends of the portion of the accommodating member 100 provided with the heating member 110. By axially and circumferentially limiting the axial ends of the portion of the accommodating member 100 provided with the heating member 110, the installation stability of the heating member 110 in the accommodating member 100 is ensured, thereby also improving the relative stability between the heating member 110 and the aerosol generating matrix 2000, ensuring the heating consistency and air intake consistency of the aerosol generating matrix 2000, thereby ensuring the consistency of the suction effect.

[0065] In one embodiment, see Figure 2 and Figure 6The bottom end of the portion of the accommodating component 100 where the heating element 110 is disposed is sleeved on the base 300, and the bottom end of the portion of the accommodating component 100 where the heating element 110 is disposed is abutted against the base 300, so that the bottom end of the portion of the accommodating component 100 where the heating element 110 is disposed is radially and axially limited by the base 300.

[0066] In one embodiment, see Figure 6 and Fig. 9 The base 300 includes a bottom plate 310 and a boss 320 protruding from the center of one side of the bottom plate 310. The bottom end of the portion of the accommodating component 100 provided with the heating element 110 is sleeved on the boss 320, and the bottom end surface of the portion of the accommodating component 100 provided with the heating element 110 abuts against the bottom plate 310, thereby preventing the heating element 110 from changing position on the base 300.

[0067] In one embodiment, see Figure 4 and Figure 5 The positioning member 400 is sleeved outside the aerosol generating matrix 2000; a limiting groove 421 is formed on the inner wall of the bottom end of the positioning member 400, and the limiting groove 421 has a first abutting surface 4211 facing the heating element 110, and the limiting groove 421 also has a second abutting surface 4212 vertically connected to the first abutting surface 4211. The second abutting surface 4212 is sleeved outside the top of the portion of the accommodating component 100 provided with the heating element 110, and the second abutting surface 4212 abuts against at least part of the outer peripheral wall of the top of the portion of the accommodating component 100 provided with the heating element 110, so that the top of the portion of the accommodating component 100 provided with the heating element 110 can be radially and axially limited.

[0068] In one embodiment, see Figure 4 and Figure 5 The positioning member 400 includes a top plate 410 and a convex ring 420 formed on the bottom side of the top plate 410. The top plate 410 is fixed to the top end surface of the accommodating component 100, and the convex ring 420 is inserted into the accommodating component 100. The convex ring 420 is sleeved outside the aerosol generating matrix 2000. A limiting groove 421 is formed on the inner side wall of the bottom end of the convex ring 420.

[0069] In one embodiment, the supporting gas cutting member 200 is mounted on the positioning member 400. The supporting gas cutting member 200 is engaged with the positioning member 400.

[0070] In one embodiment, see Fig.10, the size of the portion of the accommodating component 100 provided with the heating element 110 along the first direction X is larger than the size of the portion of the accommodating component 100 provided with the heating element 110 along the second direction Y; the size of the portion of the accommodating component 100 provided with the heating element 110 along the second direction Y is set to be smaller than the outer diameter of the aerosol generating matrix 2000; the first direction X and the second direction Y are respectively perpendicular to the axial direction of the accommodating component 100.

[0071] The size of the portion of the accommodating component 100 provided with the heating element 110 along the second direction Y is set to be smaller than the outer diameter of the aerosol generating substrate 2000. When the aerosol generating substrate 2000 is inserted into the portion of the accommodating component 100 provided with the heating element 110, the side wall of the portion of the accommodating component 100 provided with the heating element 110 along the second direction Y will squeeze the aerosol generating substrate 2000, thereby ensuring that the portion of the accommodating component 100 provided with the heating element 110 is in full contact with the aerosol generating substrate 2000, so that the heat generated by the portion of the accommodating component 100 provided with the heating element 110 can be quickly and efficiently transferred to the aerosol generating substrate 2000, thereby ensuring the heating effect of the aerosol generating substrate 2000. On the other hand, the aerosol generating substrate 2000 can also be installed and limited by the portion of the accommodating component 100 provided with the heating element 110, so as to ensure the installation stability of the aerosol generating substrate 2000 in the portion of the accommodating component 100 provided with the heating element 110.

[0072] In addition, the size of the portion of the accommodating component 100 provided with the heating element 110 along the first direction X is larger than the size of the heating element 110 along the second direction Y, so that when the portion of the accommodating component 100 provided with the heating element 110 squeezes the aerosol generating matrix 2000 along the second direction Y, although the aerosol generating matrix 2000 is deformed in the first direction X, the aerosol generating matrix 2000 and the portion of the accommodating component 100 provided with the heating element 110 can still form a first gap 500 along the first direction X for airflow to flow through.

[0073] The first direction X and the second direction Y are both directions perpendicular to the axial direction of the portion of the accommodating component 100 where the heating element 110 is disposed, and the first direction X and the second direction Y are perpendicular to each other.

[0074] In one embodiment, see Figure 2 and Figure 3, a plurality of pores 2210 are formed on the hollow section 2200 of the aerosol generating substrate 2000, and a part of the external airflow will enter the hollow section 2200 through the pores 2210 when entering the accommodating component 100. In the present application, since the part of the accommodating component 100 provided with the heating element 110 is sleeved outside the substrate section 2100 of the aerosol generating substrate 2000, the airflow will pass through the part of the accommodating component 100 provided with the heating element 110 before entering the substrate section 2100, so that the airflow temperature entering the substrate section 2100 is relatively high, and the high-temperature airflow takes away the aerosol generated by the substrate section 2100, and the cooling speed is relatively slow, which is easy to cause the phenomenon of burning the mouth, while the airflow introduced into the hollow section 2200 is a low-temperature airflow, so that the cooling of the aerosol can be heated, and the phenomenon of burning the mouth can be reduced.

[0075] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
