The first fixing section 421 may be fixed on the back surface 212 of the circuit board 210 by welding, so that a reasonable connection strength is provided between the first fixing section 421 and the circuit board 210, and the first fixing section 421 is prevented from being separated from the first surface 311 under the action of the pulling force. The second fixing section 422 may also be fixed on the second surface 321 of the negative electrode portion 320 by means of welding, so that the second fixing section 422 and the second fixing section have reasonable connection strength, and the connection strength is not too large or too small, and when the connection strength is too small, the second fixing section 422 can be separated from the second surface 321 under the action of small pulling force, and when the connection strength is too large, the second fixing section 422 still cannot be separated from the second surface 321 under the action of large pulling force.

fixed sections

Ensuring that the electronic atomizing device 10 meets the environmental requirements of the relevant country and region. On the other hand, only the battery cell 300 can be recovered, specifically, the negative electrode body 420 is pulled by force, so that the negative electrode body 420 is separated from the second surface 321 of the battery cell 300, and the welded connection relationship between the negative electrode body 420 and the battery cell 300 is released, at this time, when a tensile force is applied to the battery cell 300, the battery cell 300 does not drive the integrated module 200 to move through the negative electrode body 420, so that the battery cell 300 is taken out of the accommodating cavity 111 alone for recovery treatment, and the electrode assembly 400 and the integrated module 200 are still located in the accommodating cavity 111. Therefore, it is possible to meet the actual situation. The battery cell 300 can be recycled independently, and the battery cell 300, the electrode assembly 400 and the integrated module 200 can be recycled simultaneously.

Meanwhile, the negative electrode body 420 is an FPC flat cable, so that the negative electrode body 420 has reasonable flexibility, and can be bent and straightened freely, thereby improving convenience of the negative electrode body 420 in the installation and welding processes, and finally improving the assembly efficiency of the electronic atomization device 10.
