[0027] See also Figures 1 to 4 The heating component 100 provided in the embodiment of the present application is used for an aerosol generating device 1000. The heating component 100 includes a shell 10, a receiving tube 20 and a first sealing member 30. The shell 10 is provided with an installation cavity 11 and includes a first bracket 12 and a second bracket 13 connected to each other; the receiving tube 20 is provided with a loading cavity 21 with an opening at one end, and an end of the receiving tube 20 close to the opening of the loading cavity 21 is provided with a flange portion 22 extending outward, the first bracket 12 and the second bracket 13 are respectively located on the side where the first surface 221 and the second surface 222 of the flange portion 22 are located and clamp the flange portion 22, wherein the first surface 221 and the second surface 222 are respectively connected to the inner surface 23 and the outer surface 24 of the receiving tube 20; the first sealing member 30 is located between the first bracket 12 and the first surface 221, and the first sealing member 30 seals the gap between the first bracket 12 and the first surface 221.

[0028] Among them, the aerosol generating device is a device that generates aerosol by heating rather than burning an aerosol generating substrate. The device generally includes a heating component 100 and a support frame 200, and the heating component 100 can be installed on the support frame 200. The heating component 100 is generally arranged around the aerosol generating substrate. The heating component 100 can be used to generate heat, thereby heating the aerosol generating substrate to generate an aerosol.

[0029] Specifically, the heating component 100 is used to heat the aerosol generating substrate to generate an aerosol. The heating component 100 includes a shell 10, a accommodating tube 20 and a first sealing member 30. The shell 10 is provided with an installation cavity 11. The shell 10 also includes a first bracket 12 and a second bracket 13. The installation cavity 11 can be a space enclosed by the first bracket 12 and the second bracket 13, and the first bracket 12 and the second bracket 13 can be connected to each other by snapping or screwing. Of course, the first bracket 12 and the second bracket 13 can be connected by other elements. In this example, the first bracket 12 and the second bracket 13 are not directly connected.

[0030] The structure of the accommodation tube 20 may be a hollow cylindrical structure, such that the accommodation tube 20 includes an inner surface 23 and an outer surface 24 . The containing tube 20 can form a loading chamber 21, and an opening is formed at one end of the loading chamber 21, and the aerosol generating matrix can be inserted into the loading chamber 21 through the opening; a flange portion 22 extending outward is provided at one end of the containing tube 20 close to the opening of the loading chamber 21, and the shape of the flange portion 22 can be a circular ring or a rectangular ring, and the flange portion 22 includes a first surface 221 and a second surface 222 opposite to each other, the first surface 221 is connected to the inner surface 23 of the containing tube 20 (that is, the inner wall of the containing tube 20), and the second surface 222 is connected to the outer surface 24 of the containing tube 20 (that is, the outer wall of the containing tube 20), the first bracket 12 is located on the side where the first surface 221 of the flange portion 22 is located, and the second bracket 13 is located on the side where the second surface 222 of the flange portion 22 is located, and the flange portion 22 located between the first bracket 12 and the second bracket 13 can be clamped by the first bracket 12 and the second bracket 13.

[0031] The structure of the first seal 30 can be an annular structure. For example, the first seal 30 can be a square ring structure or a circular ring structure, and the annular structure of the first seal 30 can be a closed annular structure or a non-closed annular structure. The first seal 30 is located between the first bracket 12 and the first surface 221, so that the first seal 30 can seal the gap between the first bracket 12 and the first surface 221.

[0032] In this way, by providing an installation cavity 11 in the shell 10 of the heating component 100, and providing a first bracket 12 and a second bracket 13 connected to each other in the installation cavity 11, and then providing a loading cavity 21 with an open end on the receiving tube 20 in the heating component 100, a flange portion 22 that can extend outward along the opening is provided on the receiving tube 20 close to the end of the opening of the loading cavity 21, the first bracket 12 and the second bracket 13 are respectively located on the side where the first surface 221 and the second surface 222 of the flange portion 22 are located, the first surface 221 is connected to the inner surface 23 of the receiving tube 20, the second surface 222 of the flange portion 22 is in contact with the second bracket 13, and the second surface 222 is connected to the outer surface 24 of the receiving tube 20, so that the flange portion 22 can be clamped by the first bracket 12 and the second bracket 13. Then, by setting a first seal 30 between the first bracket 12 and the first surface 221, the gap between the first bracket 12 and the first surface 221 can be sealed, thereby preventing the aerosol in the accommodating tube 20 from leaking from the gap to outside the heating component 100 and affecting the normal operation of other components in the aerosol generating device 1000.

[0033] See also Figure 3 In some embodiments, the first bracket 12 is provided with a mounting groove 121 , and the first sealing member 30 is disposed in the mounting groove 121 .

[0034] Specifically, the first bracket 12 is provided with a mounting groove 121 on the plane where the first bracket 12 and the first surface 221 meet, and the shape and size of the mounting groove 121 can be adapted to the first sealing member 30. For example, if the first sealing member 30 is a circular ring structure, and the cross section of the first sealing member 30 of the circular ring structure cut by a plane perpendicular to the first surface 221 is circular, then the structure of the mounting groove 121 is also a circular ring structure, and the cross section of the mounting groove 121 of the plane perpendicular to the first surface 221 is circular; if the first sealing member 30 is a square ring structure, and the cross section of the first sealing member 30 of the square ring structure cut by a plane perpendicular to the first surface 221 is square, then the structure of the mounting groove 121 is also a square ring structure, and the cross section of the mounting groove 121 of the plane perpendicular to the first surface 221 is square, so that the first sealing member 30 can be arranged in the mounting groove 121.

[0035] In this way, by installing the first seal 30 in the installation groove 121 opened on the first bracket 12, the first seal 30 is prevented from shifting, and the gap between the first bracket 12 and the flange portion 22 can be better sealed to prevent aerosol from leaking into other components. In addition, during assembly, the first seal 30 can be installed in the installation groove 121 in advance, which is convenient for quickly locating the position of the first seal 30 during assembly.

[0036] See also Figure 4In some embodiments, the first surface 221 is provided with an annular groove 2211 , and the first sealing member 30 is at least partially accommodated in the annular groove 2211 .

[0037] Specifically, an annular groove 2211 adapted to the first seal 30 is opened on the first surface 221. For example, the first seal 30 is a circular ring structure, and the cross-section of the first seal 30 with a circular ring structure cut by a plane perpendicular to the first surface 221 is circular, then the structure of the annular groove 2211 is also a circular ring structure, and the cross-section of the annular groove 2211 with a plane perpendicular to the first surface 221 is circular; or, the first seal 30 is a square ring structure, and the cross-section of the first seal 30 with a square ring structure cut by a plane perpendicular to the first surface 221 is square, then the structure of the annular groove 2211 is also a square ring structure, and the cross-section of the annular groove 2211 with a plane perpendicular to the first surface 221 is square.

[0038] At least part of the structure of the first seal 30 is accommodated in the annular groove 2211. For example, the first seal 30 is a circular ring structure, and the cross-section of the first seal 30 with a circular ring structure cut by a plane perpendicular to the first surface 221 is circular, then the structure of the annular groove 2211 is also a circular ring structure, and the cross-section of the annular groove 2211 cut by a plane perpendicular to the first surface 221 is circular, so that the first seal 30 can be completely accommodated in the annular groove 2211; when the cross-section of the annular groove 2211 cut by a plane perpendicular to the first surface 221 is semicircular, the mounting groove 121 and the annular groove 2211 can form a closed circular pipe structure, so that the first seal 30 is partially accommodated in the annular groove 2211.

[0039] In this way, by at least partially accommodating the first sealing member 30 in the annular groove 2211 opened on the first surface 221, the gap between the first bracket 12 and the flange portion 22 can be better sealed to prevent aerosol from leaking into other components. In addition, during assembly, the first sealing member 30 can be pre-installed in the annular groove 2211, which facilitates quick positioning of the first sealing member 30 during assembly.

[0040] See also Figure 5 In some embodiments, the second bracket 13 includes a side wall 131 and an extension wall 132. The side wall 131 of the second bracket is arranged around and encloses a cavity 135. The extension wall 132 protrudes and extends toward the center of the cavity 135 to enclose a through hole 133. A rib 134 is provided on the side of the extension wall 132 facing the first bracket 12. The flange portion 22 is supported by the rib 134. The contact area between the flange portion 22 and the rib 134 is smaller than the area of ​​the side of the extension wall 132 facing the first bracket 12.

[0041] Specifically, the second bracket 13 includes a side wall 131 and an extension wall 132. The side wall 131 of the second bracket can be arranged around the accommodating tube 20 and can enclose a cavity 135. The side wall 131 of the second bracket includes an inner wall 1311 and an outer wall 1312. The extension wall 132 is arranged on the inner wall 1311, so that the extension wall 132 protrudes and extends toward the center of the cavity 135, and the extension wall 132 can form a through hole 133 adapted to the opening size of the accommodating tube 20, so that the accommodating tube 20 can pass through the through hole 133.

[0042] A rib 134 is provided on the side of the extension wall 132 facing the first bracket 12. The rib 134 can be used to support the flange portion 22, so that the flange portion 22 is arranged on the rib 134 without contacting the extension wall 132, thereby making the flange portion 22 clamped by the first bracket 12 and the second bracket 13, and the contact area between the rib 134 and the extension wall 132 is smaller than the area of ​​the side of the extension wall 132 facing the first bracket 12, so that the contact area between the second surface 222 of the flange portion 22 and the rib 134 is smaller than the area of ​​the side of the extension wall 132 facing the first bracket 12.

[0043] In this way, by opening a rib 134 on the extension wall 132 of the second bracket 13, the flange portion 22 is supported on the rib 134, which can reduce the contact area between the flange portion 22 and the second bracket 13, thereby reducing the heat transferred from the flange portion 22 to the second bracket 13 and achieving a heat insulation effect.

[0044] See also Figure 5 In some embodiments, the convex rib 134 is a closed annular structure, and the convex rib 134 is arranged around the through hole 133; or there are multiple convex ribs 134, and the multiple convex ribs 134 are arranged around the through hole 133 at intervals from each other.

[0045] Specifically, the structure of the convex rib 134 can be a closed annular structure, and is arranged around the through hole 133. For example, the structure of the convex rib 134 can be a closed circular ring structure, a square structure, etc. arranged around the through hole 133; or, the structure of the convex rib 134 is composed of multiple convex ribs 134 arranged around the through hole 133 at intervals from each other. For example, the structure of the convex rib 134 can be composed of multiple wedge blocks spaced apart from each other and arranged around the through hole 133.

[0046] In this way, by providing a rib 134 on the extension wall 132 of the second bracket 13 so that the flange portion 22 is supported on the rib 134, the contact area between the flange portion 22 and the second bracket 13 can be reduced, thereby reducing the heat transferred from the flange portion 22 to the second bracket 13 and achieving a heat insulation effect.

[0047] Please refer again Figure 4 and Figure 5In some embodiments, the second bracket 13 includes a side wall 131, and the first bracket 12 includes a side wall 122. One of the side wall 131 of the second bracket and the side wall 122 of the first bracket is provided with a snap-fitting member 14, and the other is provided with a snap-fitting groove 15 corresponding to the snap-fitting member 14. The snap-fitting member 14 is snap-fitted with the corresponding snap-fitting groove 15 to connect the first bracket 12 and the second bracket 13.

[0048] Specifically, the second bracket 13 includes a side wall 131, and the first bracket 12 also includes a side wall 122. One of the side wall 131 of the second bracket and the side wall 122 of the first bracket is provided with a snap-fitting piece 14, and the other is provided with a snap-fitting groove 15 corresponding to the snap-fitting piece 14. For example, the side wall 131 of the second bracket is provided with a snap-fitting piece 14, which may be a protrusion or a wedge, and the side wall 122 of the first bracket is provided with a snap-fitting groove 15 corresponding to the snap-fitting piece 14, which may be a groove or a wedge-shaped groove, or the side wall 122 of the first bracket is provided with a snap-fitting piece 14, which may be a protrusion or a wedge, and the side wall 131 of the second bracket is provided with a snap-fitting groove 15 corresponding to the snap-fitting piece 14, which may be a groove or a wedge-shaped groove. By snapping the snap-fitting piece 14 and the snap-fitting groove 15, the first bracket 12 and the second bracket 13 can be detachably connected.

[0049] Optionally, the first bracket 12 and the second bracket 13 can be connected by bolt connection. For example, screw holes are provided on the side wall 122 of the first bracket and the side wall 131 of the second bracket, and the first bracket 12 and the second bracket 13 are connected by screwing nuts into the screw holes.

[0050] In this way, by providing a snap fit 14 on one of the side walls 131 of the second bracket and the side walls 122 of the first bracket, and providing a snap fit groove 15 corresponding to the snap fit 14 on the other, and by engaging the snap fit 14 with the corresponding snap fit groove 15 to connect the first bracket 12 and the second bracket 13, the clamping force between the first seal 30 and the flange portion 22 can be increased, thereby improving the sealing effect of the flange portion 22 and the first seal 30.

[0051] Please refer again Figure 1 In some embodiments, the other end of the loading chamber 21 is a closed end 25; and / or the inner surface 23 of the containing tube 20 is coated with an anti-rust glaze layer.

[0052] Specifically, the end of the loading chamber 21 away from the opening is closed to form a closed end 25, so that the aerosol generating matrix can only extend into the containing tube 20, thereby fixing the aerosol generating matrix and guiding the generated aerosol to flow out from the opening of the loading chamber 21; and / or a layer of anti-rust glaze is coated on the inner surface 23 of the containing tube 20, so as to prevent the aerosol from corroding the inner surface 23 of the loading chamber 21, thereby improving the service life of the aerosol generating device 1000.

[0053] See also Figure 6 and Figure 7 In some embodiments, a through hole 251 is provided at the other end of the loading chamber 21 , and the heating assembly 100 further includes a second sealing member 40 , which is disposed in the through hole 251 to seal the through hole 251 .

[0054] Specifically, a through hole 251 is provided at one end of the loading chamber 21 away from the opening, and the through hole 251 can connect the loading chamber 21 and the installation chamber 11. The heating assembly 100 also includes a second seal 40, which is arranged in the through hole 251 so that the through hole 251 is sealed by the second seal 40. The structure and size of the second seal 40 are adapted to the shape and size of the through hole 251. For example, the shape of the through hole 251 is circular, and the structure of the second seal 40 is cylindrical; the shape of the through hole 251 is rectangular, and the structure of the second seal 40 is a column.

[0055] In this way, by opening a through hole 251 at the end of the loading chamber 21 away from the opening and using the second sealing member 40 to seal the through hole 251, the inner surface 23 of the containing tube 20 can be conveniently coated with an anti-rust glaze layer when the through hole 251 is opened, and the provision of the second sealing member 40 can also prevent aerosols from flowing from the through hole 251 into other components and affecting the operation of other components.

[0056] See also Figure 7 In some embodiments, the second sealing member 40 includes a first sub-portion 41, a second sub-portion 42 and a third sub-portion 43. The first sub-portion 41 and the third sub-portion 43 are respectively located at opposite ends of the second sub-portion 42. The second sub-portion 42 is penetrated by a through hole 251. The first sub-portion 41 is located inside the loading chamber 21, and the third sub-portion 43 is located outside the loading chamber 21. At least one of the first sub-portion 41, the second sub-portion 42 and the third sub-portion 43 closes the through hole 251.

[0057] Specifically, the structure of the second sealing member 40 includes a first sub-portion 41, a second sub-portion 42 and a third sub-portion 43. The materials of the first sub-portion 41, the second sub-portion 42 and the third sub-portion 43 can be sealing materials such as rubber and silicone. The first sub-portion 41 and the third sub-portion 43 are respectively located at opposite ends of the second sub-portion 42. For example, the first sub-portion 41 is located in the loading chamber 21, and the third sub-portion 43 is located outside the loading chamber 21 (that is, the third sub-portion 43 is located in the installation chamber 11), or the third sub-portion 43 is located in the loading chamber 21, and the first sub-portion 41 is located outside the loading chamber 21 (that is, the first sub-portion 41 is located in the installation chamber 11); the second sub-portion 42 is penetrated by a through hole 251, The first sub-portion 41 and the third sub-portion 43 are connected; at least one of the first sub-portion 41, the second sub-portion 42 and the third sub-portion 43 closes the through hole 251. For example, the first sub-portion 41 is connected to the closed end 25 of the accommodating tube 20, and the orthographic projection of the first sub-portion 41 at the closed end 25 covers the through hole 251, thereby closing the through hole 251; the third sub-portion 43 is connected to the closed end 25 of the accommodating tube 20, and the orthographic projection of the third sub-portion 43 at the closed end 25 covers the through hole 251, thereby closing the through hole 251; the second sub-portion 42 is penetrated by the through hole 251 and is tangent to the closed end 25 of the accommodating tube 20, thereby closing the through hole 251.

[0058] In this way, through the first sub-portion 41, the second sub-portion 42 and the third sub-portion 43 included in the second sealing member 40, and at least one of the first sub-portion 41, the second sub-portion 42 and the third sub-portion 43 closing the through hole 251, the inner surface 23 of the accommodating tube 20 can be conveniently coated with an anti-rust glaze layer when the through hole 251 is opened, and aerosol can be prevented from flowing from the through hole 251 into other components and affecting the operation of other components.

[0059] See also Figure 7 In some embodiments, the heating assembly 100 further includes a spacer 50, which is disposed on the bottom wall 26 of the accommodating tube 20, and the spacer 50 is made of a breathable material and / or has a breathable hole.
