At this time, the movable disk is no longer squeezed, the reset spring is reset, so that the movable disk is firmly against the fixed plate to prevent the limit block from detaching from the limit groove, thereby completing the connection between the waterproof mechanism and the electric heating mechanism.

[0004] However, the existing technology still has shortcomings: the process of installing the electric heating mechanism and the waterproof mechanism requires passing through the opening on the fixed disk inside the waterproof mechanism, squeezing the movable disk and compressing the return spring, and other steps, which are complicated to operate. In addition, there is also the problem of aligning the limit block with the limit groove. If the alignment is inaccurate, the limit block may be separated from the limit groove, affecting the connection effect. Therefore, it is necessary to improve the existing technology, simplify the installation process, and improve the accuracy and stability of the connection. Utility Model Content
