when the water molecules move to the outer side of the waterproof gasket 17, the water molecules are ejected out of the space by the annular bulge part on the outer side of the waterproof gasket 17;
when the water molecules enter the gap between the waterproof gasket 17 and the casing body 111 through the outside of the waterproof gasket 17, on one hand, the water molecules are thrown out of the gap again due to the rotation of the waterproof gasket 17, and on the other hand, the waterproof gasket 17 comprises a plurality of annular protrusions and recesses which are matched with the plurality of annular protrusions and recesses of the casing body 111 to form a concave-convex structure, and the concave-convex structure blocks the water molecules layer by layer, so that the water molecules are prevented from entering the gap between the bearing 13 and the movable impeller 14. Further, the axial heights of the plurality of annular protrusions of the waterproof gasket 17 are different, so that the path of the water molecules moving toward the bearing 13 is more complicated, and the water molecules are further prevented from approaching the bearing 13, thereby further improving the waterproof effect. The term "plurality" as referred to in this embodiment includes at least one and two or more. It should be understood by those skilled in the art that the numbers recited in the present examples are for illustrative purposes only and should not be construed as limiting the present invention in any way.
