Water pump installation structure of mop cleaning barrel

Abstract

A water pump installation structure of a mop cleaning barrel comprises a barrel body, a transmission shaft, a wheel cover and a pump wheel, the pump wheel is covered with the wheel cover, and the transmission shaft penetrates through a penetrating hole in the wheel cover and then is connected with the pump wheel. The installation structure is characterized in that a step-shaped concave cavity is formed in the bottom of the barrel body, the pump wheel and the wheel cover are both arranged in the concave cavity, the opening end of the concave cavity is covered with a pump cover so that the concave cavity can form a clear water cavity, the transmission shaft upwards penetrates out of the pump cover, and a water spraying channel and a water supplementing channel which are communicated with the clear water cavity and the outside are formed in the pump cover. An inner cavity of the wheel cover is communicated with the water spraying channel in an inserted mode through a water outlet channel in the wheel cover, and the inner cavity of the wheel cover is communicated with the clean water cavity so that water can enter the inner cavity. The concave cavity is formed in the barrel body to serve as a lower shell in a traditional pump shell, one part is omitted, consumables are reduced, a pair of molds is omitted, and cost is effectively reduced.
