The guide rail can be installed on the wall of a car washing room. The mounting frame is slidingly connected to the guide rail. The plurality of swing air fans are rotationally connected to the mounting frame through a plurality of hinged seats. The swing mechanism comprises a connecting frame, a swing motor, a rotating arm and a plurality of connecting arms. The connecting frame is fixed to the mounting frame. The swing motor is fixed to the connecting frame. One end of the rotating arm is fixedly connected to the output shaft of the swing motor. One end of each of the plurality of connecting arms is hinged to the arm body of the rotating arm, and the other end is hinged to the plurality of swing air fans.

[0003] In the process of implementing the technical solution of the present disclosure, it is found that at least the following problems exist in the related technology:
