Background technique

The spray fan is a device that uses the rotation of the electric fan to cooperate with the spray device to cool down and relieve the heat. It can increase the air humidity evenly while accelerating the air circulation. The structure of a conventional spray fan is not much different from that of an ordinary floor fan. Both use a chassis as the center of gravity at the bottom of the fan to fix the entire upper structure of the fan. The spray fan is only provided with a water tank that can store water on the chassis. The water is transported to the mesh cover of the fan through the peripheral conduit, and the water mist is blown out by the rotation of the fan blades.

However, the structure of the existing spray fan has many defects in actual use.
