[0029] The cross-sectional shape of the accommodating channel in the shell is circular, and the accommodating channel has a central axis 7 corresponding to the central position of the circle. The aerosol generating device includes a positioning member 21, an atomizing cylinder 30, a connecting cylinder 41 and an air inlet member 42 arranged in the extension direction of the central axis 7. The entire shell is arranged in the extension direction of the central channel. The shell has an air inlet 14. The air inlet member 42 is positioned and installed on the frame 12, and the air inlet channel of the air inlet member 42 is connected to the air inlet 14. The air inlet member 42 is sealed and connected to the connecting cylinder 41 through an air inlet joint 43, and the air inlet channel in the air inlet member 42 is connected to the internal space of the connecting cylinder 41 through the internal channel of the air inlet joint 43. The connecting cylinder 41 is positioned and installed on the frame 12, and the connecting cylinder 41 is sealed and matched with one end of the atomizing cylinder 30 facing away from the positioning member 21.

[0030] A heating cylinder 33 is provided in the atomizing cylinder 30. The heating cylinder 33 is arranged in the extension direction of the central axis 7. One end of the heating cylinder 33 facing away from the positioning member 21 is sealed with the connecting cylinder 41, and one end of the heating cylinder 33 facing the positioning member 21 is also sealed with the atomizing cylinder 30, so that the heating cylinder 33 encloses a heating channel 34, or the heating cylinder 33 and part of the atomizing cylinder 30 enclose a heating channel 34.

[0031] In one embodiment, please refer to Figures 2 to 4 The positioning member 21 is installed at the opening 13 of the shell member. Since the connecting cylinder 41 is positioned and installed on the frame 12, the atomizing cylinder 30 is clamped and fixed between the positioning member 21 and the connecting cylinder 41 in the extension direction of the central axis 7, and can ensure the sealing of the atomizing cylinder 30 and the connecting cylinder 41; the positioning member 21 has a positioning structure, which cooperates with the end of the atomizing cylinder 30 facing the positioning member 21 to limit the position of the atomizing cylinder 30 in a plane perpendicular to the extension direction of the central axis 7.

[0032] Specifically, please refer to Figure 2 and Figure 4 The positioning member 21 includes a positioning ring, which is arranged around the central axis 7. The positioning ring encloses a socket channel 25 connected to the opening 13. The radial single-side cross-section of the positioning ring is L-shaped. The positioning ring includes a sleeve portion 22 and an end ring portion 23 connected to the sleeve portion 22. The extension direction of the sleeve portion 22 is the same as the extension direction of the central axis 7, and the end ring portion 23 is perpendicular to the extension direction of the central axis 7. At least part of the sleeve portion 22 is located in the opening 13 of the shell member, so as to achieve the fixing of the position of the positioning ring in a plane perpendicular to the central axis 7.

Through the cooperation between the end ring portion 23 and the atomizer barrel 30, the position of the atomizer barrel 30 in the plane perpendicular to the extension direction of the central axis 7 is fixed.

[0033] In one embodiment, please continue to refer to Figures 2 to 4 The positioning structure includes a protrusion 24 arranged on the end ring portion 23, and the corresponding end of the atomizer cylinder 30 has a groove 311. There are multiple protrusions 24, and the multiple protrusions 24 are arranged at intervals around the central axis 7. The number of corresponding grooves 311 corresponds to the number of protrusions 24. The protrusions 24 cooperate with the grooves 311 to fix the position of the atomizer cylinder 30 in a plane perpendicular to the extension direction of the central axis 7 through the end ring portion 23.

[0034] Of course, in some other embodiments, the positioning structure may also include a groove 311 , and the corresponding end of the atomizer cylinder 30 has a protrusion 24 , which cooperates with the groove 311 to limit the fixation of the position of the atomizer cylinder 30 in a plane perpendicular to the extension direction of the central axis 7 .

[0035] In some other embodiments, the aerosol generating device may not be provided with the positioning piece 21, and the shell 11 and the frame 12 may enclose a socket channel 25 on one side of the opening 13, or the frame 12 or the shell 11 may separately enclose a socket channel 25; the positioning structure is located on the frame 12 and close to the opening 13, and the position of the atomizer cylinder 30 may be limited by the cooperation between the atomizer cylinder 30 and the positioning structure.

[0036] In one embodiment, please continue to refer to Figure 2 and Figure 3 The positioning member 21 has a first side surface facing the atomizing cylinder 30 in the extension direction of the central channel, and the first side surface is located on the end ring portion 23. The atomizing cylinder 30 includes a cylinder portion 31 and a protruding portion 32. The protruding portion 32 is arranged on the inner cylinder wall of the cylinder portion 31. The protruding portion 32 can be a cantilever structure. The protruding portion 32 is arranged around the central axis 7, and the protruding portion 32 also extends toward the central axis 7. The atomizing cylinder 30 is sealed with the end of the heating cylinder 33 through the protruding portion 32. The protruding portion 32 is close to the end of the cylinder portion 31 that cooperates with the positioning member 21. The protruding portion 32 has a second side surface facing the positioning member 21 in the extension direction of the central axis 7. The first side surface, the second side surface and the inner wall surface of the cylinder portion 31 enclose a recess 35.

[0037] In the embodiment where the heating channel 34 is formed by only the heating cylinder 33, the recess 35 is located between the heating channel 34 and the socket channel 25; in the embodiment where the heating channel 34 is formed by partially enclosing the heating cylinder 33 and the atomizing cylinder 30, the recess 35 is located at the heating channel 34. The mounting portion 51 of the clamping member 50 is located in the recess 35 to achieve the mounting of the clamping member 50 on the channel wall of the accommodating channel.

[0038] Of course, in other embodiments, the recess 35 can also be formed by the atomizer cylinder 30, or can also be formed by the positioning member 21; in the embodiment where the recess 35 is only formed by the positioning member 21, the portion of the positioning member 21 close to the opening 13 encloses the socket channel 25, and the recess 35 is located between the socket channel 25 and the heating channel 34.

[0039] In one embodiment, please continue to refer to Figure 2 , Figure 3 and Figure 5 For the clamping member 50, the mounting portion 51 in the clamping member 50 is arranged around the central axis 7, the mounting portion 51 is an annular structure, and the mounting portion 51 is embedded in the recess 35 of the accommodating channel; there are multiple elastic clamping portions 52, and the multiple elastic clamping portions 52 are all connected to the radial inner side of the mounting portion 51, and the multiple elastic clamping portions 52 extend toward the direction of the central axis 7.

[0040] Of course, in other embodiments, the mounting portion 51 may also be composed of a plurality of arc segments arranged at intervals in the circumferential direction around the central axis 7 , and each arc segment is provided with an elastic clamping portion 52 .

[0041] Alternatively, in an embodiment where the mounting portion 51 is an annular structure, the elastic clamping portion 52 may also be an annular structure continuously arranged around the central axis 7 .

[0042] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The mounting portion 51 has an outer circumferential surface away from the central axis 7 and an inner circumferential surface close to the central axis 7. The elastic clamping portion 52 is connected to the inner circumferential surface of the mounting portion 51. The outer circumferential surface of the mounting portion 51 is in contact with the channel wall of the accommodating channel. In order to facilitate the installation of the mounting portion 51 in the recess 35, the outer circumferential surface of the mounting portion 51 is provided with an annular groove 511 arranged around the central axis 7. The mounting portion 51 has a first end close to the positioning member 21 and a second end away from the positioning member 21 in the arrangement direction of the central axis 7. The annular groove 511 is located between the first end and the second end. During the installation of the mounting portion 51, the first end and the second end of the mounting portion 51 can be deformed in the direction away from the central axis 7 to reduce the size of the mounting portion 51 in the extension direction of the central axis 7, so as to facilitate the installation of the mounting portion 51 in the recess 35.

[0043] The annular groove 511 provided on the outer circumferential surface of the mounting portion 51 facilitates the deformation of the first end and the second end of the mounting portion 51 , that is, facilitates the positioning and installation of the mounting portion 51 on the channel wall of the accommodating channel.

[0044] Of course, in some other embodiments, the mounting portion 51 is made of a rubber material with relatively low hardness, so that even if the annular groove 511 is not provided on the outer peripheral surface of the mounting portion 51 , the positioning installation of the mounting portion 51 can be easily achieved.

[0045] In one embodiment, please continue to refer to Figure 2 , Figure 3 and Figure 5 The groove wall surface of the annular groove 511 on the mounting portion 51 is an arc-shaped surface, so that the structural strength of the mounting portion 51 can be avoided from being affected by setting an angle in the annular groove 511 .

[0046] Of course, if the deformation of the first end and the second end of the mounting portion 51 is not large, the structural shape of the wall of the annular groove 511 may not be limited. For example, the cross-sectional shape of the annular groove 511 may be rectangular, triangular or trapezoidal.

[0047] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The elastic clamping portion 52 in the clamping member 50 is connected to the inner circumferential surface of the mounting portion 51, and the elastic clamping portion 52 is connected to the first end of the mounting portion 51, so that the elastic clamping portion 52 is close to the opening 13 of the shell member to improve the clamping stability of the aerosol generating product 6.

[0048] Alternatively, in some other embodiments, the elastic clamping portion 52 may also be located between the first end and the second end of the mounting portion 51 , or may also be provided at the second end of the mounting portion 51 .

[0049] In one embodiment, please refer to Figure 2 and Figure 5 The clamping member 50 is an integrally formed structure, and the clamping member 50 is made of an elastic rubber material. The elastic clamping portion 52 includes a connecting arm 521 and a cantilever 522. One end of the connecting arm 521 is connected to the mounting portion 51, and the other end is connected to the cantilever 522. The connecting arm 521 extends toward the central axis 7, and the extending direction of the connecting arm 521 is perpendicular to the extending direction of the central axis 7. Of course, the extending direction of the connecting arm 521 can also be less than 90° or greater than 90° with the extending direction of the central axis 7.

[0050] In one embodiment, please continue to refer to Figure 2 and Figure 5 One end of the cantilever 522 is connected to one end of the connecting arm 521, and the other end of the cantilever 522 is a cantilevered end, that is, a free end. The extension direction of the cantilever 522 and the extension direction of the connecting arm 521 have a non-zero angle, that is, the extension direction of the cantilever 522 and the extension direction of the connecting arm 521 do not coincide with each other. The cantilever 522 extends toward the central axis 7, and the distance between the cantilever 522 and the central axis 7 gradually decreases in the direction away from the opening 13. In this way, the elastic clamping portion 52 can be formed as a whole into a barb shape with the opening facing away from the socket channel 25. This arrangement facilitates the insertion of the aerosol generating product 6 into the heating channel 34 along the opening 13 and the socket channel 25, which helps to facilitate the insertion of the aerosol generating product 6 into the accommodating channel.

[0051] Alternatively, in some other embodiments, the cantilever 522 is connected to the end of the connecting arm 521 at the middle of its extension direction, and the distance between the cantilever 522 and the central axis 7 gradually decreases in the direction away from the opening 13, which also facilitates the insertion of the aerosol generating product 6 into the accommodating channel.

[0052] The cantilever 522 is used to be elastically clamped on the outer peripheral surface of the aerosol generating product 6. When the elastic clamping part 52 is in a free state, the minimum distance between the two cantilevers 522 in the two elastic clamping parts 52 arranged opposite to each other in the radial direction is smaller than the diameter of the aerosol generating product 6, and the maximum distance between the two cantilevers 522 is larger than the diameter of the aerosol generating product 6, so that after the aerosol generating product 6 is inserted into the accommodating channel, the end of the cantilever 522 away from the opening 13 can be deformed so that at least part of the cantilever 522 is pressed against the outer peripheral surface of the aerosol generating product 6; after the aerosol generating product 6 with a larger radial dimension is inserted into the accommodating channel, the connecting arm 521 may also be elastically deformed, so that the connecting arm 521 and the cantilever 522 are elastically deformed so that the cantilever 522 is pressed against the outer peripheral surface of the aerosol generating product 6, which can prevent the aerosol generating product 6 from escaping from the accommodating channel, and facilitate the normal use of the aerosol generating product 6.

[0053] In one embodiment, please refer to Figure 2 and Figure 5 For the cantilever 522, the cross-sectional shape of the cantilever 522 is a square, and the cantilever 522 has four side surfaces arranged around its length direction, and the cantilever 522 also has an end surface located at its free end. Among the four side surfaces of the cantilever 522, the side surface facing the central axis 7 is inclined relative to the central axis 7 to form a clamping surface, and the clamping surface is in contact with the outer peripheral surface of the aerosol generating product 6. When the elastic clamping portion 52 is in a free state, the distance between the clamping surface and the central axis 7 gradually decreases in the direction away from the socket channel 25, so that after the aerosol generating product 6 is inserted into the accommodating channel, as the cantilever 522 is deformed, the clamping surface is completely pressed against the outer peripheral surface of the aerosol generating product 6, which can increase the contact area between the cantilever 522 and the aerosol generating product 6, so that the clamping force of the clamping member 50 on the aerosol generating product 6 can be further improved to prevent the aerosol generating product 6 from escaping from the accommodating channel.

[0054] Of course, in some other embodiments, the free end of the cantilever 522 is a pointed tip, no end surface is provided on the cantilever 522 , and the cantilever 522 only has four side surfaces, one of which is used to be pressed against the outer peripheral surface of the aerosol generating product 6 .

[0055] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
