| description | The water pump shell comprises a whole composed of a first shell body, a second shell body and a third shell body, the top of the first shell body is provided with a first ring edge, the upper end of the first ring edge is downwards and obliquely narrowed to form a first slope portion, the middle of the second shell body partially protrudes downwards to form a protruding portion, and the third shell body is provided with a second ring edge. A second slope part is arranged on the periphery of the protruding part, the first slope part and the second slope part abut against each other, a plurality of enough attaching areas exist between the first shell and the second shell, the good effect that water cannot permeate into the driving cavity from the pressurizing cavity is achieved, in addition, rotating water flow in the pressurizing cavity can flow back into the pressurizing cavity along the second slope part, and the rotating water flow can flow back into the driving cavity along the second slope part.
