Abstract
The invention relates to an electric fan which aims to overcome the defects that an existing water spraying electric fan is complex in structure due to the fact that the fan comprises a water pump, and the efficiency of the water pump is low. The electric fan comprises a fan head, a supporting base and a water storage device. The fan head comprises a motor and fan blades. Radial blade water conveying pipelines are arranged on the blades. Water outlets are formed in the front faces of the blades. A shaft pipeline is arranged on a rotating shaft of the motor, and the blade water conveying pipelines are communicated with the water storage device through a hub water channel, the shaft pipeline and a water pipe. The water storage device comprises a water bag, a bucket-shaped component and a spring. A water adding opening and a water fetching opening are formed in the water bag, and the bucket-shaped component accommodates the water bag; the spring is used for exerting pressure on the water bag. According to the electric fan, the water storage device conveys water to the water outlets in the blades through potential energy accumulated by the water storage device, the water in the blade water conveying pipelines flows out from the water outlets in an accelerated mode under the centrifugal effect when the blades rotate and is blown out by wind, and the water is vaporized to absorb heat and reduce the temperature. According to the electric fan, the water pump is not needed, and the electric fan is simple in structure.
