[0002] With the gradual improvement and popularization of automation control, the application field of solenoid valves is also expanding, especially in the field of small household appliances, where the application and popularization are relatively extensive. At present, no matter how the structure of the solenoid valve changes, its principle is to generate a magnetic field through the electromagnetic coil, and then the static iron core generates electromagnetic suction, thereby sucking the moving iron core up to open the solenoid valve. This principle is similar to the process of positive and negative magnets attracting each other. Although the working principles are basically the same, the structure of the solenoid valve itself can affect the efficiency of the solenoid valve. However, most of the current solenoid valves have complex structures, resulting in cumbersome production processes, which is not conducive to automated assembly production, and seriously affects the production efficiency of the solenoid valve.

At this time, the valve outlet channel 101 is installed at the center position of the coil frame 103. An electromagnetic coil 102 is provided on the side of the valve outlet channel 101, and the electromagnetic coil 102 can be wound on the coil frame 103. A rubber coating layer 11 is provided on the outside of the valve body 1.

[0030] Both the static iron core 2 and the moving iron core 3 are provided with an inner portion of the valve outlet passage 101, and the cooperation between the two can complete the position movement of the moving iron core 3;

[0031] The static iron core 2 can be installed at the bottom of the valve outlet channel 101, the moving iron core 3 is arranged inside the valve outlet channel 101 and located at the top of the static iron core 2, an elastic member 5 is arranged between the moving iron core 3 and the static iron core 2, the elastic member 5 can be a spring, a step lower edge 1 is provided at the bottom end of the moving iron core 3, a step lower edge 2 is provided at the top end of the static iron core 2, the top end of the elastic member 5 is sleeved on the step lower edge 1, and the bottom end of the elastic member 5 is sleeved on the step lower edge 2, and the elastic member 5 is used to drive the moving iron core 3 to always have a tendency to stay away from the static iron core 2;

[0032] During use, after the electromagnetic coil 102 is energized, the moving iron core 3 uses the electromagnetic force between the moving iron core 3 and the static iron core 2 to realize the movement of the moving iron core 3. At this time, the moving iron core 3 can move toward the position of the static iron core 2 and be adsorbed onto the top of the static iron core 2, thereby achieving the purpose of controlling the moving iron core 3 to move in the valve outlet channel 101.

[0033] The steering seat 4 is disposed at the top of the valve body 1. A space 1 401 and a space 2 402 are disposed inside the steering seat 4.

Specifically, the top of the moving iron core 3 is inserted into the space 1 401 along the through opening 406. At this time, the elastic member 5 located between the moving iron core 3 and the static iron core 2 can be used to drive the moving iron core 3 to always have a tendency to seal the steering tube 1 404 (the top of the moving iron core 3 is sealed to the entrance of the steering tube 1 404).

[0037] When it is necessary to transfer and redirect the liquid, the electromagnetic coil 102 is energized, and the moving iron core 3 uses the electromagnetic force between the moving iron core 3 and the static iron core 2 to move toward the static iron core 2, so that the top of the moving iron core 3 seals the opening 406, so that the liquid that enters the space 1 401 along the inlet pipe 403 cannot enter the space 2 402 along the opening 406, and can only be transported along the space 1 401 and the steering pipe 1 404;
