Preferably, the surface of the gear is fixedly connected with fan blades, and the fan blades rotate to drive the gear to rotate.
Preferably, the surface of the gear is engaged with the toothed chain, and the teeth of the gear are engaged with each other.
Preferably, the fan blades and the air checking channel are located on the same horizontal line, so that the fan blades are blown better while air is conveniently fed.
Preferably, the support frame is triangular and equilateral, so that the toothed chains can move simultaneously.
Preferably, a toothed chain is arranged inside each edge of the support frame.
Preferably, the metal plate is deformed by being pressed and has a certain elastic restoring force.
Preferably, one side of the noise board, which is far away from the metal plate, is movably connected with a return spring.
