[0049] In addition, in order to better describe the cooperation between the bottom cover 3 and the shell 1, it is assumed that the bottom cover 3 includes a first part located at the top and a second part located at the bottom. Of course, the first part and the second part are integrally formed; in order to make the bottom cover 3 better cooperate with the shell 1, the second part has an extension structure toward the circumferential side compared with the first part, so that after the first part is inserted into the shell 1, the extension section of the second part is just stuck at the bottom of the outer side of the shell 1, so that the shell 1 and the bottom cover 3 are installed. At the same time, the outer surface of the first part has a bottom cover clamping position and a bottom cover protrusion set for detection, and correspondingly, the inner surface of the shell 1 has a shell protrusion and a shell clamping position set at intervals, so that the bottom cover protrusion cooperates with the shell clamping position, and the bottom cover clamping position cooperates with the shell protrusion, so that the bottom cover 3 and the shell 1 are fixed.

The first oil-absorbing cotton 5 has a shape that is compatible with the first clamping position and the air inlet pipe so that it can fill the bottom cover 3.

[0062] In addition, two ends of the first oil-absorbing cotton 5 are in contact with the bottom of the atomizing core 2 and the bottom cover 3 respectively, so as to prevent the first oil-absorbing cotton 5 from moving and affecting the air path and the liquid absorption effect.

[0063] In addition, in one of the embodiments, the bottom of the bottom cover 3 has a depression, and a second oil-absorbing cotton 8 is arranged in the depression, and the upper end of the second oil-absorbing cotton 8 is in contact with the first oil-absorbing cotton 5 .

[0064] In a specific embodiment, the atomizer further includes a sealing seat 6, which is disposed in the housing 1, and whose outer side is connected to the inner surface of the bottom of the housing 1, whose bottom is connected to the bottom cover 3, and whose inner side cooperates with the outer periphery of the atomizer core 2.
