[0034] The utility model sets the water outlet and the water inlet at the bottom of the shell, and assembles the floating seat, the valve head seat and the valve head in the shell, and cooperates with the locking structure to constrain the valve head to move upward. Thus, under the clamping action of the valve head and the shell, the floating seat and the valve head seat are fixed in the shell. It can effectively reduce the assembly connection of parts, realize rapid assembly, improve assembly production efficiency, and meet production needs.
