Door opening and closing device and electrical apparatus

Abstract

The door opening and closing device is used to open a door body disposed on a main body. The door opening and closing device includes: a base, a driving mechanism, a linkage gear and a door rotation mechanism. The linkage gear is rotatably disposed on the base and is in transmission connection with the driving mechanism. The door rotation mechanism is disposed between the linkage gear and the base. An end of the door rotation mechanism is connected to the linkage gear, and another end of the door rotation mechanism is connected to the door body. In a condition that the driving mechanism drives the linkage gear to rotate, the door rotation mechanism drives the door body to rotate relative to the main body to open or close the door body.
