The inner cylinder 470c includes a conical cylinder with a diameter gradually increasing from top to bottom, the extending end 413c of the first water inlet valve 4a is inserted into the inner cylinder 470c, and the top surface of the outer cylinder 470b is higher than the top surface of the inner cylinder 470 c. The inner cylinder 470c has a diameter D2 at its small end, a diameter D3 at its large end, and a cylindrical configuration at its extended end 413c with a diameter D1. In one embodiment, D2 < D1 < D3, thereby ensuring that the extended end 413c sealingly engages the second seal ring 470.
