[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] See also Figure 1-Figure 5 A quick-assembled solenoid valve structure includes a shell 10, a water-stop component 30, a valve head seat 40 and a valve head 50, characterized in that the water-stop component 30, the valve head seat 40 and the valve head 50 are assembled in the shell 10 from bottom to top in sequence, a water inlet 110 is provided on the lower surface of the shell 10, and a water outlet 120 is provided on the side wall of the shell 10 around the water-stop component 30, a floating cavity 300 is formed between the water-stop component 30 and the valve head seat 40, an elastic element 60 is provided in the floating cavity 300, and the elastic element 60 is used to apply a downward force to the water-stop component 30 so that the water-stop component 30 blocks the water inlet 110 downward, and the valve head 50 and the shell 10 are connected to each other by a detachable connection structure.

[0028] The utility model arranges the water inlet and the water outlet on the shell, and then assembles the water stop assembly, the valve head seat and the valve head in the shell from bottom to top in sequence, and under the action of the clamping structure, it can constrain the valve head to move upward, so as to constrain the installation position of the water stop assembly and the valve head seat by constraining the position of the valve head, thereby achieving rapid assembly and reducing the assembly connections between components, thereby optimizing the assembly process and improving assembly efficiency.

[0029] See also Figure 1 and Figure 2 The water-stop assembly 30 includes an annular diaphragm 310 connected to the valve head seat 40 in an arc shape, the lower end of the annular diaphragm 310 is connected to a sealing portion 320, and the sealing portion 320 is provided with a floating seat 20; the floating seat 20 is provided with a water inlet channel 210 interconnected with the water inlet 110 and the floating cavity 300; a water-stop cavity 410 is provided between the valve head seat 40 and the valve head 50, a connecting channel 420 is provided between the water-stop cavity 410 and the floating cavity 300, and a drainage channel 430 is connected between the water-stop cavity 410 and the water outlet 120; the valve head 50 is used to control the plug 500 to block the water inlet end of the drainage channel 430.

[0030] In the utility model, a mounting hole penetrating from top to bottom is arranged in the middle of the blocking portion 320, and the floating seat 20 is fixedly arranged in the mounting hole.

[0031] Closed state: the valve head 50 controls the plug 500 to block the water inlet end of the drainage channel 430. In this state, water is input from the water inlet 110 through the water inlet channel 210 into the floating chamber 300. Since the drainage channel 430 is blocked, water is blocked in the floating chamber 300 and the water stop chamber 410 and cannot be discharged. The water pressure prevents the sealing part 320 and the floating seat 20 from moving upward, thereby cutting off the connection between the water inlet 110 and the water outlet 120.

[0032] Open state: the valve head 50 controls the plug 500 to move upward, so that the water inlet end of the drainage channel 430 is blocked. In this state, water flows from the water inlet 110, then sequentially through the water inlet channel 210, the floating chamber 300, the connecting channel 420 and the water stop chamber 410, and finally is discharged from the water stop chamber 410 through the drainage channel 430. In this state, due to the absence of water pressure, the blocking part 320 and the floating seat 20 float upward under the deformation of the annular diaphragm 310. When the blocking part 320 and the floating seat 20 float upward, the water inlet 110 and the water outlet 120 are connected to each other.

[0033] See also Figure 1 and Figure 2 The water inlet channel 210 is a channel that runs through from top to bottom. The elastic element 60 is connected to a needle 610 . The needle 610 is movably inserted into the water inlet channel 210 . There is a water inlet gap between the water inlet channel 210 and the needle 610 .

[0034] See also Figure 1 and Figure 5The first limiting boss 100 is arranged around the water inlet 110. When the solenoid valve is in a closed state, the lower surface of the floating seat 20 fits with the upper surface of the first limiting boss 100. The first limiting boss 100 not only fits with the blocking portion 320 to close the valve body, but also can constrain the assembly position of the blocking portion 320, that is, when the plug-in assembly is performed from top to bottom, the blocking portion 320 is plugged downward into the inside of the housing 10 until the blocking portion 320 fits with the first limiting boss 100, indicating that the assembly is in place.

[0035] See also Figure 1 and Figure 5 A second limiting boss 101 is provided in the middle of the housing 10, and an annular limiting portion 301 is provided on the upper portion of the annular diaphragm 310; the annular limiting portion 301 is arranged between the second limiting boss 101 and the valve head seat 40, and is clamped and fixed by the two.

[0036] The second limiting boss 101 has the function of constraining the installation position of the annular diaphragm 310 , and can cooperate with the valve head seat 40 to clamp and fix the annular limiting portion 301 to fix the annular diaphragm 310 .

[0037] See also Figure 2 , Figure 4 and Figure 5 A plurality of limit blocks 140 are arranged on the peripheral wall of the valve head 50, and a plurality of limit spring sheets 130 are arranged on the peripheral wall of the housing 10; the lower surface of the limit spring sheet 130 abuts against the upper surface of the limit block 140 to form a clamping fixation.

[0038] See also Figure 4 and Figure 5 The inner wall of the housing 10 is provided with a guide groove 150 with an upper opening, the limiting spring piece 130 extends into the guide groove 150, and the limiting clamping block 140 is movably inserted into the guide groove 150 and fixedly engaged with the limiting spring piece 130. The cooperation between the guide groove 150 and the limiting clamping block 140 is used to restrict the valve head 50 from rotating relative to the housing 10, and facilitates plug-in assembly.

[0039] In the present invention, the annular diaphragm 310 and the blocking portion 320 are connected to form an integrated structure.

[0040] See also Figure 2 The housing 10 is provided with an output channel 160 which is interconnected with the drainage channel 430 , and the output channel 160 is interconnected with the water outlet 120 .

[0041] See also Figure 1 and Figure 2 A filter element 70 is connected to the bottom of the housing 10 .

[0042] See also Figure 1 and Figure 2 The filter element 70 includes a filter body 720 and a connecting ring 710 , and the connecting ring 710 is detachably connected to the housing 10 .
