[0031] The lower end of the hollow iron core 17 abuts against the return spring 16, and the lower end of the return spring 16 abuts against the valve body shell 21;

[0032] The solenoid valve body 2 comprises a valve body shell 21, in which a first water inlet 22, a first water through hole 221, a second water inlet 25 and a second water through hole 251 are provided, wherein the first water inlet 22 is connected to the first water through hole 221 for allowing water of one temperature to enter the valve body, and the second water inlet 25 is connected to the second water through hole 251 for injecting water of another temperature into the valve body. In this embodiment, hot water is injected into the first water inlet 22, and cold water is injected into the second water inlet 25;

[0033] The upper ends of the first water hole 221 and the second water hole 251 are connected to the fusion cavity, and the plug 15 is movably arranged in the fusion cavity.
