The mouthpiece 11 comprises a shell 113 and a mouthpiece air outlet pipe 112 connected to the inner side of the shell 113, and a mouthpiece cavity 111 is formed between the shell 113 and the mouthpiece air outlet pipe 112. The sealing piece 12 comprises a first air outlet hole 121 penetrating through the thickness direction thereof, the first air outlet hole 121 is in air communication with the mouthpiece air outlet pipe 112, and the sealing piece 12 seals the mouthpiece cavity 111 so that the mouthpiece air outlet pipe 112 is isolated from the mouthpiece cavity 111. The liquid storage container 14 forms an atomization cavity 131 therein, the atomization cavity 131 is used for collecting aerosol, and the atomization cavity 131 is in air communication with the first air outlet hole 121.

[0033] The first air outlet hole 121 of the sealing piece 12 is in air communication with the mouthpiece air outlet pipe 112, and the sealing piece 12 seals the mouthpiece cavity 111, so that the problem of air leakage of the atomizer mouthpiece can be solved, even if air enters the mouthpiece 11 from outside the liquid storage container 14, it will not enter the mouthpiece cavity 111, so the user does not need to suck air to fill the mouthpiece cavity 111, and a specific negative pressure can be achieved by taking a small puff, which can greatly improve the starting speed of the product.

[0034] At the same time, the aerosol in the atomization cavity 131 cannot enter the mouthpiece cavity 111, and the aerosol will not enter the mouthpiece cavity 111 to produce condensation, and the aerosol will not mix with the air in the mouthpiece cavity 111, so as to improve the saturation degree.

[0035] In some embodiments, the sealing piece 12 is an elastomer, that is, a sealing body made of an elastic material, for example, the elastic material is silica gel or TPU, etc. Here, silica gel and TPU are only examples and do not limit the present application, and other materials can also be used.

[0036] In some embodiments, as shown in Figure 5As shown, the mouthpiece air outlet tube 112 includes an inlet end 1121 and an outlet end 1122, the outlet end 1122 of the mouthpiece air outlet tube 112 is used for the user to suck with the mouth, and the inlet end 1121 of the mouthpiece air outlet tube 112 is annularly abutted to the edge of the first air outlet hole 121.

[0037] In some other embodiments, the outer periphery of the mouthpiece air outlet tube 112 is embedded in the first air outlet hole 121 with an interference fit.

[0038] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 5 , in order to further improve the sealing effect, a first protruding structure 123 is arranged between the outer wall of the mouthpiece air outlet tube 112 and the inner wall of the first air outlet hole 121, for example, the first protruding structure 123 is an annular protrusion arranged on the inner wall of the first air outlet hole 121. Here, the annular protrusion is only an example and does not limit the present application, and other forms are also possible. In some other embodiments, when the flange 122 is inserted into the mouthpiece air outlet tube 112, a first protruding structure 123 is arranged between the inner wall of the mouthpiece air outlet tube 112 and the outer wall of the flange 122.

[0039] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 5 , the outer periphery of the sealing platform 124 is in contact with the inner wall of the shell 113. Similarly, in order to improve the sealing effect, a second protruding structure 126 is arranged between the outer wall of the sealing platform 124 and the inner wall of the shell 113, for example, the second protruding structure 126 is an annular protrusion arranged on the outer wall of the sealing platform 124.

[0041] In some embodiments, the shell 113 of the mouthpiece 11 is at least partially transparent or translucent. Since the aerosol in the atomization cavity 131 cannot enter the mouthpiece cavity 111, there is no condensation of aerosol entering the mouthpiece cavity 111, so as not to affect the appearance of the transparent or translucent mouthpiece 11. It can be understood that at least part of it can be part or all.

[0044] The conventional liquid storage container 14 is sealed by the upper and lower sections, and the sealing area is large. However, in the present embodiment, the liquid injection hole 142 is small, so the sealing area is reduced by several tens of times. The smaller the area, the better the sealing.

[0045] In some embodiments, as shown in Figure 5 , the liquid storage container 14 further comprises a cover 143, a liquid storage member 144 and a seat 145, and the cover 143 is detachably connected with the seat 145.
