There are many types of adapters, such as commonly used power adapters, network adapters, and display adapters. At present, in order to prevent the adapter from being damaged by excessive temperature when in use and the electronic equipment connected to it, a heat dissipation port is usually opened on the adapter shell for ventilation and heat dissipation. However, since dust can easily enter the inside of the adapter shell from the heat dissipation port of the adapter, causing the power adapter to accumulate a lot of dust, people usually adopt a structure described in a Chinese utility model patent with application number 202223088554.0 and patent name as a power adapter heat dissipation structure. A dustproof structure is set on the inner wall of the adapter shell and located at the heat dissipation port. The dustproof structure includes a stepper motor and a baffle.
