The shell 1 is designed into an upper shell 1a and a lower shell 1b in a split mode, and processing and forming of each cavity, each channel and each hole-shaped structure in the shell 1 are facilitated.

Secondly, the inner wall of the water inlet 121 is provided with a shrinkage opening 1211, the size of the shrinkage opening 1211 is smaller than the radius of the piston member 2, so that the piston member 2 can be prevented from falling out of the housing 1 from the water inlet 121 under the condition of shaking (such as shaking caused in the process of transporting the product).
