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 and production, and seriously affects the production efficiency of the solenoid valve.

[0028] Reference Figure 1-3 , a solenoid valve for steering, which can be used in small household appliances, comprises a valve body 1, a static iron core 2, a moving iron core 3, a steering seat 4 and an elastic member 5, wherein:

[0029] A valve outlet channel 101 is provided inside the valve body 1. The valve outlet channel 101 can be an independent pipe structure. A coil frame 103 is also provided inside the valve body 1. A chamber for accommodating the valve outlet channel 101 is opened at the middle position of the coil frame 103. 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 8 is provided on the outside of the valve body 1. The rubber coating layer 8 can prevent water from entering the electromagnetic valve, for example, so that the electromagnetic valve can be used in a working environment with water vapor.

[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 provided with a top of the valve body 1, and a steering space 401 is provided inside the steering seat 4. An inlet pipe 402 and a steering channel 1 403 are provided on the steering seat 4. The inlet pipe 402 is connected to the steering space 401, and the steering channel 1 403 is connected to the steering space 401. A steering channel 2 201 connected to the valve outlet channel 101 is provided inside the static iron core 2. The steering channel 2 201 can be connected to the inlet pipe 402 and the steering channel 1 403 through the valve outlet channel 101.

[0034] Since the steering seat 4 is mounted on the top surface of the valve body 1, the moving iron core 3 is inserted into the interior of the steering seat 4. Figure 3 As shown, the top of the moving iron core 3 is inserted into the turning space 401, and 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 turning channel 1 403 (the top of the moving iron core 3 is sealed to the entrance of the turning channel 1 403);

[0035] In this embodiment, referring to Figure 3 As shown, when the solenoid valve is used, because the moving iron core 3 always has the tendency to seal the entrance of the steering channel 1 403, the liquid entering the steering space 401 from the inlet pipe 402 may also be gas, and cannot be transmitted along the steering channel 1 403. The liquid inside the steering space 401 can only enter the steering channel 2 201 along the valve outlet channel 101, and finally be transported along the steering channel 201.

[0036] When it is necessary to transfer and divert 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 bottom of the moving iron core 3 seals the diverting channel 201, so that the liquid entering the diverting space 401 along the inlet pipe 402 cannot be transferred along the diverting channel 201, and can only be transferred along the diverting space 401 and the diverting channel 1 403;

[0037] By controlling the energization of the electromagnetic coil 102, the lifting of the moving iron core 3 can be controlled. The lifting of the moving iron core 3 can control the opening and closing of the steering channel 1 403 and the steering channel 2 201, and can realize the switching function of the electromagnetic valve. The overall structure is simple, which can reduce the complexity of the production process, facilitate automated assembly and production, improve production efficiency, and reduce operating costs.

[0038] In one possible embodiment, Figure 3 As shown, in order to ensure that the top of the moving iron core 3 has good sealing performance, a sealing rubber head 301 is installed on the top of the moving iron core 3, and the sealing rubber head 301 can effectively seal the bottom entrance of the steering channel 403. In addition, in order to facilitate the moving iron core 3 to seal the bottom entrance of the steering channel 403 when it is in a vertical moving state, the entrance of the steering channel 403 is on the same center line as the moving iron core 3;

[0039] In order to ensure that the bottom end of the moving iron core 3 has good sealing performance, a sealing rubber head 2 302 is installed at the bottom end of the moving iron core 3. A mounting groove can be opened on the bottom end surface of the moving iron core 3. The sealing rubber head 2 302 is embedded in the mounting groove. When the electromagnetic coil 102 is energized and the moving iron core 3 moves toward the direction of the static iron core 2, the sealing rubber head 2 302 located at the bottom of the moving iron core 3 can effectively seal the steering channel 2 201.

[0040] In one possible embodiment, Figure 1 or Figure 3 As shown, the bottom of the steering seat 4 can be detachably mounted on the top surface of the valve body 1, and the bottom end of the steering seat 4 can be mounted to the top of the valve body 1 by screws, that is, the bottom of the steering seat 4 is provided with a threaded hole 1, and the top of the valve body 1 is provided with a threaded hole 2, and the screws are installed into the threaded hole 1 and the threaded hole 2 to complete the installation of the steering seat 4 and the valve body 1;

[0041] In this embodiment, the detachable setting between the steering seat 4 and the valve body 1 facilitates the assembly and installation of the steering seat 4, avoids the complicated process of integrated setting, and facilitates improving production efficiency. In addition, when the internal components of the steering seat 4 are damaged, the steering seat 4 and the valve body 1 can also be disassembled for maintenance;

[0042] In one possible embodiment, Figure 3 As shown, in order to achieve that the steering seat 4 can be sealed and installed to the top end of the valve body 1, the bottom end of the steering seat 4 and the top end of the valve body 1 are sealed by a sealing ring 6.

[0043] In one possible embodiment, Figure 3 As shown, in order to enable the static iron core 2 to be sealed and installed to the bottom of the valve outlet channel 101, an installation groove is opened on the outer circumferential surface of the static iron core 2, and a sealing ring 7 is installed in the installation groove. The static iron core 2 is sealed and installed to the bottom of the valve outlet channel 101 through the sealing ring 7.
