The invention relates to an electric fan, and discloses an electric fan with a water spraying function. The electric fan with the water spraying function aims to overcome the defects that an existing electric fan with a water spraying function comprises a water pump, so that the structure is complex and the efficiency of the water pump is low. The electric fan comprises an electric fan head, a supporting device supporting the electric fan head and a water storage device. A radial blade water pipe is arranged on each blade. A water outlet communicated with the corresponding water pipe is formed in the front face of each blade. An axial shaft pipe is arranged on a motor rotation shaft. The blade water pipes are communicated with the shaft pipes through a water channel arranged in a hub. The shaft pipes are communicated with the water storage device through a water pipe. According to the watering electric fan, water in the radial blade water pipes on the blades flow out from the water outlets under the centrifugal effect of the water when the blades rotate, is blown by air to be vaporized to absorb heat and lower the temperature. After the water in the blade water pipes is thrown out, water is sucked from the water storage device, so that water continues to be sprayed out. According to the electric fan, a water pump does not need to be arranged, and the structure of the watering electric fan is simple.
