Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] like Figures 1 to 5 As shown, the embodiment of the utility model provides a solenoid valve, which includes a coil component 10, a valve seat component 20, a clamping portion 30 and a connecting portion 40. Among them, the coil component 10 includes a coil body 11 and a magnetic frame 12, and the magnetic frame 12 includes a first mounting plate 121 and a second mounting plate 122 arranged oppositely. The coil body 11 is arranged between the first mounting plate 121 and the second mounting plate 122, and a avoidance hole 1221 is arranged on the second mounting plate 122. One end of the valve seat component 20 passes through the avoidance hole 1221 and is connected to the coil component 10. The clamping portion 30 is located on the side of the second mounting plate 122 away from the first mounting plate 121, and is located on the outer periphery of the valve seat component 20. The clamping portion 30 includes a connecting section 31 and a clamping section 32. The clamping section 32 is spaced apart from the second mounting plate 122. The two ends of the connecting section 31 are respectively connected to the second mounting plate 122 and the clamping section 32, and a clamping space is formed between the clamping section 32 and the second mounting plate 122. One end of the connecting portion 40 is arranged on the valve seat component 20, and the other end of the connecting portion 40 is arranged in the clamping space. Among them, one of the clamping groove 321 and the clamping protrusion 401 is arranged on the side of the clamping section 32 close to the second mounting plate 122, and the other of the clamping groove 321 and the clamping protrusion 401 is arranged on the end of the connecting portion 40 that penetrates the clamping space. The clamping protrusion 401 and the clamping groove 321 are clamped and matched, and the valve seat component 20 is connected to the magnetic guide frame 12 through the clamping portion 30 and the connecting portion 40.

[0044] By applying the technical solution of the utility model, the clamping part 30 is arranged on the second mounting plate 122, and the connecting part 40 is arranged on the valve seat component 20, and the magnetic frame 12 and the valve seat component 20 are connected by the mutual clamping cooperation of the clamping part 30 and the connecting part 40. The above setting has a simple structure and is convenient for connecting and assembling the valve seat component 20 and the magnetic frame 12. In the traditional technical solution, the magnetic frame and the valve seat component are connected by fasteners. Such a setting is cumbersome to operate and has low assembly efficiency. Compared with the traditional technical solution, the setting of this solution is more convenient to operate and has higher assembly efficiency.

[0047] Furthermore, there is an angle between the clamping section 32 and the connecting section 31, and the clamping section 32 is bent toward the valve seat component 20. Specifically, the clamping section 32 and the connecting section 31 form a bent structure, and the clamping section 32 and the second mounting plate 122 are parallel to each other. The clamping section 32 and the second mounting plate 122 cooperate to clamp one end of the connecting portion 40 that is inserted into the clamping space. In this way, the clamping section 32 and the second mounting plate 122 are respectively abutted against one end of the connecting portion 40 that is inserted into the clamping space, which can limit the relative position of the connecting portion 40 and the second mounting plate 122 in the axial direction, further improve the stability of the connecting portion 40, and avoid the possibility of the connecting portion 40 moving in the axial direction.

[0048] like Figure 3 and Figure 6 As shown, in this embodiment, the connecting portion 40 is sleeved and fixed on the valve seat component 20, and the outer periphery of the connecting portion 40 is inserted into the clamping space. Such an arrangement facilitates the mutual connection between the connecting portion 40 and the valve seat component 20.

[0049] like Figure 3 , Figures 7 to 12 As shown, the valve seat component 20 is provided with a mounting cavity 201 and a valve port 202 which are interconnected, and one end of the valve seat component 20 away from the valve port 202 passes through the avoidance hole 1221 and is connected to the coil component 10. An avoidance notch 402 is provided on the outer periphery of the connecting portion 40, and the avoidance notch 402 is used to avoid the clamping portion 30.

[0050] In this embodiment, the extending direction of the clamping section 32 is the same as the radial direction of the connecting portion 40, the extending direction of the avoidance notch 402 is the same as the radial direction of the connecting portion 40, and one end of the avoidance notch 402 extends to the outer peripheral surface of the connecting portion 40. During the assembly process, the connecting portion 40 is sleeved on the valve seat component 20, and then the end of the valve seat component 20 away from the valve port 202 is passed through the avoidance hole 1221, and the connecting portion 40 is rotated so that the avoidance notch 402 is arranged opposite to the clamping portion 30; the connecting portion 40 is moved in the direction close to the first mounting plate 121 so that the connecting portion 40 is abutted against the second mounting plate 122; the connecting portion 40 is rotated until the outer peripheral edge of the connecting portion 40 is inserted into the clamping space, and the connecting portion 40 is rotated so that the clamping protrusion 401 is clamped with the clamping groove 321.

[0051] Among them, this scheme does not limit the specific number of the clamping parts 30. In this embodiment, two clamping parts 30 are provided, and the two clamping parts 30 are spaced apart along the circumference of the valve seat component 20, and two avoidance notches 402 are provided, and the avoidance notches 402 are arranged corresponding to the clamping parts 30. Such an arrangement can improve the stability of the clamping parts 30 clamping the connecting part 40, and improve the stability of fixing the connecting part 40.

[0052] like Figures 2 to 6 As shown, in this embodiment, the connecting portion 40 includes a connecting tube 41 and a connecting ring 42 that are connected to each other.

The connecting tube 41 is arranged in this way, which can increase the contact area between the connecting tube 41 and the valve seat component 20 and improve the stability of the welding of the connecting tube 41 and the valve seat component 20.

[0053] like Fig.10 As shown, in this embodiment, one end of the connecting tube 41 is folded outward to form a connecting ring 42. This arrangement has a simple structure and is convenient for processing the connecting portion 40.

[0054] like Fig.11 and Fig.12 As shown, further, a plurality of the clamping protrusions 401 are provided, and the plurality of clamping protrusions 401 are spaced apart along the circumference of the connecting portion 40. Specifically, the clamping protrusions 401 are spaced apart along the circumference of the connecting ring 42 on the connecting ring 42.

After the stamping is completed, a notch structure is formed on the second mounting plate 122, and the notch structure is interconnected with the avoidance hole 1221. This solution does not limit the forming method of the clamping groove 321. In this embodiment, the clamping groove 321 is formed by a stamping process.

[0056] Furthermore, the solution of this embodiment is to stamp the connection ring 42 to form a clamping protrusion 401 protruding toward the connection tube 41. Such a configuration has a simple structure and facilitates the processing of the clamping protrusion 401.

[0057] like Figures 2 to 6As shown, specifically, the coil body 11 is provided with a mounting hole 101, and the mounting hole 101 is arranged opposite to the avoidance hole 1221. The valve seat component 20 includes a valve seat body 21 and a sleeve 22 connected to each other, one end of the sleeve 22 away from the valve seat body 21 is inserted into the mounting hole 101 and has an interference fit with the mounting hole 101, and the valve port 202 is provided on the valve seat body 21, and the valve seat body 21 is provided with a valve cavity, and the valve cavity is connected with the sleeve 22 to form the mounting cavity 201.

[0058] In this solution, the valve seat body 21 and the sleeve 22 can be configured as a separate structure or as an integrally formed structure.

[0059] In this embodiment, the valve seat body 21 and the sleeve 22 are integrally formed. Such an arrangement can improve the structural stability of the valve seat component 20.

[0060] like Figure 2 and Figure 4 As shown, the solenoid valve further includes an attractor 50, a valve needle component 60 and a core iron 70.
