[0037] like Figures 2 to 5As shown, in some embodiments, the electronic atomization device may include a housing 10, a structural member 20 and a sealing member 30. The housing 10, the structural member 20 and the sealing member 30 are assembled to form a partial power supply assembly 100, which can be assembled with an atomizer to supply power to the atomizer, and the atomizer can be used to atomize the liquid atomization medium to produce an aerosol. In some other embodiments, the housing 10, the structural member 20 and the sealing member 30 may also form a partial atomizer. In some embodiments, the housing 10 can accommodate at least part of the structural member 20, and the structural member 20 can be installed from one end of the housing 10. In some embodiments, the structural member 20 can be a bottom cover. It can be understood that in some other embodiments, the structural member 20 is not limited to a bottom cover, but can also be a bracket. In some embodiments, the structural member 20 can also be an atomization seat, that is, the structural member 20 can be at least partially installed in the housing 10 and any component that needs to be sealed and assembled between the housing 10. The sealing member 30 is sleeved on the structural member 20 to seal the gap between the structural member 20 and the housing 10. In some other embodiments, the seal 30 is not limited to being used in the power supply assembly 100, but can also be used in an atomizer.

[0038] In some embodiments, the housing 10 may be a cylindrical structure, and a hollow structure with openings 11 at both ends. A receiving cavity 12 may be formed inside the housing 10. The receiving cavity 12 may be used to receive components such as batteries and structural members 20.

[0039] like Figure 6 and Figure 7As shown, in some embodiments, the structural member 20 may be arranged at one of the openings 11 of the housing 10, specifically, the structural member 20 may be arranged at the opening 11 of the housing 10 away from the side where the atomizer is assembled. In some embodiments, the structural member 20 may be cylindrical, and the structural member 20 may include a barrel 21, and the barrel 21 may be a hollow structure with one end open. The barrel 21 may include a first part 211, a second part 212, and a third part 213, wherein the first part 211 is arranged between the second part 212 and the third part 213, and the third part 213 is located on the side of the first part 211 away from the second part 212. The first part 211, the second part 212, and the third part 213 may be integrally formed. When the structural member 20 is assembled with the housing 10, the first part 211 and the third part 213 may be arranged in the housing 10, and the outer wall thereof may be interference fit or clearance fit with the inner wall of the housing 10. The second portion 212 may be located at the opening 11, and may support the housing 10, so as to facilitate the assembly of the structural member 20 with the housing 10. The dimension of the second portion 212 in the transverse direction may be greater than the dimension of the housing 10 in the transverse direction, and an anti-slip structure 2121 may be provided on the outer wall of the second portion 212. In some embodiments, the cross-section of the housing 10 and the structural member 20 may be substantially circular, that is, the outer diameter of the second portion 212 may be greater than the inner diameter of the housing 10.

[0040] In some embodiments, the structural member 20 is further provided with a receiving groove 22, which is located between the first portion 211 and the third portion 213, and can be used to receive the sealing member 30. The receiving groove 22 can be extended along the circumference of the structural member 20. In some embodiments, the distance D1 between the notch on one side of the receiving groove 22 and the notch on the other side opposite to it can be 10mm to 20mm, and further, in some embodiments, the distance D1 can be 15.36mm. That is, the outer diameter of the third portion 213 can be 10mm to 20mm, and further can be selected as 15.36mm. In some embodiments, the distance D2 between the bottom wall on one side of the receiving groove 22 and the bottom wall on the other side opposite to it is 8mm to 15mm, and further, in some embodiments, the distance D2 can be selected as 13.68mm. In some embodiments, the height h1 of the receiving groove 22 can be 2mm to 3mm, and further, in some embodiments, the height h1 of the receiving groove 22 can be 2.8mm.

[0041] In some embodiments, the structural member 20 is further provided with a receiving groove 23, which can be arranged at one end of the receiving groove 22, and in some embodiments, the receiving groove 23 can also be arranged at both ends of the receiving groove 22. Specifically, the receiving groove 23 can be located at one end of the first portion 211, and is arranged side by side with the receiving groove 22 along the axial direction of the structural member 20, and is connected with the receiving groove 22. The receiving groove can be used to accommodate the portion of the seal 30 that is extruded along the axial direction when it is squeezed, thereby reducing the scraping glue step and avoiding the sealing failure of the seal 30. In some embodiments, the height h2 of the receiving groove 23 is greater than 0 and less than or equal to 1mm, and in some embodiments, the height h2 of the receiving groove 23 can be 0.6mm. In some embodiments, the depth h3 of the receiving groove 23 is greater than 0 and less than or equal to 0.8mm, and in some embodiments, the depth h3 of the receiving groove 23 can be 0.46mm.

[0042] In some embodiments, the structural member 20 further includes an air intake structure 24, which is disposed on the bottom wall of the cylinder 21 and protrudes toward the inner side of the cylinder 21. The air intake structure 24 may be an air intake column, and an air intake channel 241 communicating with the outside and the inner side of the cylinder 21 is formed on the inner side thereof. In some embodiments, the air intake structure 24 may be omitted.

[0043] As 3, Figure 5 , Figure 8 and Fig. 9 As shown, in some embodiments, the seal 30 may be a silicone member. Of course, it can be understood that in other embodiments, the seal 30 is not limited to being a silicone member, but may also be rubber, latex or plastic. The seal 30 includes a body 31 and a sealing portion 32. In some embodiments, the body 31 is a columnar structure as a whole, and the cross section is annular; it should be noted that the cross section may be a section in the radial direction of the body 31. In other embodiments, the body 31 is not limited to being annular, but may be cylindrical or block-shaped. In some embodiments, the sealing portion 32 is protrudingly arranged on the outer side wall of the body 31, and may be integrally formed with the body 31. In some embodiments, the sealing portion 32 may be integrally formed with the body 31 by injection molding. The sealing portion 32 may be arranged to extend along the circumference of the body 31, and may be formed by providing protruding ribs on the outer side wall of the body 31.

[0044] In some embodiments, the cross section of the body 31 is generally annular, specifically, it may be annular. In some embodiments, the body 31 may include a first end 31a and a second end 31b; the first end 31a and the second end 31b may be disposed opposite to each other and connected to each other.

[0045] In some embodiments, the sealing parts 32 may be three, and the three sealing parts 32 may be arranged at intervals along the axial direction of the body 31. In some embodiments, the three sealing parts 32 may also be arranged continuously along the axial direction of the body 31. Of course, it can be understood that in other embodiments, the sealing parts 32 are not limited to three, and may be one, two or more than three. The more the number of sealing parts 32, the better the sealing performance. When the sealing part 32 is one, it can be applied to occasions where the sealing requirements are not high. Among the three sealing parts 32, one sealing part 32 is arranged near the first end 31a, one sealing part 32 is arranged near the second end 31b, and the other sealing part 32 is arranged at the middle of the body 31 in the axial direction. In other embodiments, when the sealing part 32 is one, the sealing part 32 may be located at the middle of the body 31 in the axial direction; when the sealing part 32 is two, one of them is arranged near the first end 31a, and the other is arranged near the second end 31b; or one of them is located at the middle of the body 31 in the axial direction, and the other is arranged near the first end 31a or the second end 31b.

[0046] In some embodiments, each sealing portion 32 includes a pointed structure 321, which is protruded toward the side opposite to the body, that is, it is protruded along the assembly direction. When the seal 30 is assembled with the housing 10, the pointed structure 321 can be protruded toward the inner wall of the housing 10 to abut against the inner wall of the housing 10. In some embodiments, the longitudinal section of the sealing portion 32 can be triangular. Of course, it can be understood that in some other embodiments, the longitudinal section of the sealing portion 32 is not limited to being triangular. In some embodiments, the longitudinal section of the sealing portion 32 can also be rhombus, trapezoidal, etc. It should be noted that the longitudinal section can be a section in the axial direction when the sealing portion 30 is columnar. By setting the pointed structure 321, the sealing portion 32 can reduce the amount of glue squeezed, reduce the difficulty of assembly, and avoid problems such as difficulty in assembly and sealing failure due to scraping glue on the basis of interference assembly with the housing 10 and the structural member 20 and ensuring sealing. It should be noted that since the sealing feature of the sealing part 32 is mainly the side of the sealing part 32 that is arranged opposite to the inner wall of the housing 10, and the sharp angle structure 321 is provided, the problem of scraping glue can be better avoided compared with the semicircular volume of the sealing part of the conventional B-type ring due to the smaller volume of the sharp angle structure 321. It is easy to understand that during the assembly process, the protruding area of ​​the sharp angle structure 321 is smaller than the protruding area of ​​the sealing part of the conventional B-type ring, and thus the amount of glue squeezed is inevitably smaller than the amount of glue squeezed by the conventional B-type ring.

[0047] In some embodiments, the tips of the pointed structures 321 of at least two of the three sealing parts 32 are arranged non-aligned in the axial direction. The pointed structure 321 of the sealing part 32 arranged near the first end 31a can be arranged biased toward the second end 31b, and the pointed structure 321 of the sealing part 32 arranged near the second end 31b can be arranged biased toward the first end 31a, that is, the pointed structures 321 of the sealing parts 32 arranged near the two ends are all biased toward the middle. The pointed structure 321 of the sealing part 32 located in the middle is not biased, and the sealing part 32 located in the middle can mainly perform its sealing function. It can be understood that in some other embodiments, the pointed structure 321 of the sealing part 32 arranged near the first end 31a can also be arranged without bias, and / or the pointed structure 321 of the sealing part 32 arranged near the second end 31b can also be arranged without bias.

[0048] In some embodiments, the sealing portion 32 disposed near the first end portion 31a may include a first guide slope 322, which is formed by deflecting the pointed structure 321 toward the middle. The first guide slope 322 may extend from the first end portion 31a to the tip of the pointed structure 321, and be inclined toward the tip of the pointed structure 321. The first guide slope 322 may be formed to facilitate assembly of the sealing portion 32. In some other embodiments, the first guide slope 322 is not limited to extending from the first end portion 31a. In some embodiments, the first guide slope 322 may be a portion of the sealing portion 32 extending toward the tip of the pointed structure 321.

[0049] In some embodiments, the sealing portion 32 disposed near the second end portion 31b may include a second guide slope 323, and the second guide slope 323 may be formed by deflecting the pointed structure 321 toward the middle. The second guide slope 323 may extend from the second end portion 31b to the tip of the pointed structure 321, and be inclined toward the tip of the pointed structure 3221. The second guide slope 323 may be formed to facilitate assembly of the sealing portion 32. In some embodiments, the second guide slope 321 is not limited to extending from the second end portion 31b, and in some embodiments, the second guide slope 321 may extend from a portion of the sealing portion 32 to the tip of the pointed structure 321.

[0050] like Figure 4 and Fig. 9As shown, in some embodiments, the inner diameter D3 of the seal 30 can be 10mm to 15mm, and further, the inner diameter D3 of the seal 30 can be 13.45mm. In some embodiments, the height H of the seal 30 is 2mm to 3mm; further, the height H of the seal 30 can be selected to be 2.6mm. The maximum thickness T1 of the seal 30 can be 1mm to 1.5mm; further, in some embodiments, the maximum thickness T1 of the seal 30 can be 1.05mm. In some embodiments, the thickness T2 of the body 31 can be 0.5mm to 0.9mm; in some embodiments, the thickness T2 of the body 31 can be 0.7mm. When the sealing member 30 is assembled with the structural member 20 and the shell 10, when the main body 31 and the structural member 20 are interference fit, the thickness d1 of the portion of the main body 31 extruded toward the structural member 20 can be 0.1 mm to 0.15 mm. Specifically, in some embodiments, the thickness d1 of the extruded portion can be 0.12 mm. When the sealing member 32 is interference fit with the inner wall of the shell 10, the thickness d2 of the portion extruded toward the inner wall of the shell 10 can be 0.01 mm to 0.05 mm. Furthermore, in some embodiments, the thickness d2 of the extruded portion can be 0.03 mm.
