[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0025] See also Figure 1-Figure 3 .

[0026] The utility model discloses an anti-clogging solenoid valve, comprising:

[0027] The valve body 1 is provided with a partition plate 11 near the water outlet for separating the fluid medium, and the top of the partition plate 11 is provided with an inclined surface;

[0028] The control component 2 includes a control unit 24 arranged on the top surface of the valve body 1, a coil 25 is provided in the control unit 24, and the coil 25 is connected to the control unit 24 by signal. A moving iron core 21 is provided at one end of the control unit 24, and the moving iron core 21 is vertically slidably inserted in the valve body 1. A piston block 22 is provided below the moving iron core 21, and the bottom surface of the piston block 22 is provided with another inclined surface corresponding to the inclined surface of the partition plate 11. A first elastic unit 23 is further provided between the piston block 22 and the top surface of the valve body 1. The first elastic unit 23 is used to apply vertical downward pressure to the piston block 22. A first flow channel 221 is provided in the piston block 22, and a water inlet of the first flow channel 221 is provided on the bottom surface of the piston block 22;

[0029] The cleaning component 3 is provided in the piston block 22 and is used to clean the impurities blocked between the partition plate 11 and the piston block 22;

[0030] The pushing component 4 is arranged in the piston block 22. One end of the pushing component 4 is connected to the first flow channel 221, and the other end is connected to the cleaning component 3. When blockage occurs between the partition plate 11 and the piston block 22, the pushing component 4 is used to drive the cleaning component 3 to clean impurities.

[0031] In a specific implementation, when the solenoid valve is working, the coil 25 is energized and sends a signal to the control unit 24. The control unit 24 drives the piston block 22 to move upward through the moving iron core 21, and the first elastic unit 23 is compressed. At this time, there is a space between the piston block 22 and the partition plate 11 for the fluid medium to pass through. When impurities in the fluid medium are blocked between the piston block 22 and the partition plate 11, the fluid medium at one end of the partition plate 11 close to the water inlet of the valve body 1 is difficult to flow and accumulates. At this time, the pressure in the fluid medium increases and the liquid level rises. As the liquid level of the fluid medium continues to rise, the fluid medium contacts the bottom surface of the piston block 22 and enters the first flow channel 221. The fluid medium passes through the first flow channel 221. The channel 221 squeezes the pushing component 4, and the pushing component 4 is subjected to the pressure of the fluid medium and drives the cleaning component 3 to apply a thrust in the direction away from the partition plate 11 to the impurities blocked between the piston block 22 and the partition plate 11, thereby pushing the impurities out to make the flow channel in the valve body 1 pass. At this time, the pressure in the fluid medium decreases and the liquid level gradually drops to a predetermined value. The fluid medium in the first flow channel 221 is discharged, and the blockage cleaning is completed. When the solenoid valve is not working, the coil 25 is powered off, the first elastic unit 23 loses its constraint and drives the piston block 22 to move downward and applies downward pressure on the piston block 22. At this time, the inclined surface of the piston block 22 contacts the inclined surface of the partition plate 11, and the flow channel of the valve body 1 is closed.

[0032] According to the utility model, when a blockage occurs in the valve body 1, the pushing component 4 cooperates with the cleaning component 3 so that the fluid medium exerts force on the pushing component 4 and provides kinetic energy for the cleaning component 3 to push away impurities blocked between the piston block 22 and the partition plate 11, so that the solenoid valve has a self-cleaning function when blocked, reduces the frequency of manual maintenance, and reduces the cleaning difficulty for the staff.

[0033] Preferably, the first elastic unit 23 can be a spring in the prior art.

[0034] It should be noted that the control component 2 is common knowledge to those skilled in the art, so its structure will not be described in detail here.

[0035] In one embodiment, a chamber 222 is defined in the piston block 22 , a pressure transmission medium is present in the chamber 222 , and the chamber 222 is in communication with the water outlet of the first flow channel 221 ;

[0036] The pushing component 4 includes a push plate 41 slidingly arranged in the chamber 222, and the push plate 41 is dynamically sealed with the chamber 222. A second elastic unit 42 is also provided between the push plate 41 and the end of the chamber 222 away from the first flow channel 221. The second elastic unit 42 provides the push plate 41 with a thrust in the direction close to the first flow channel 221. A second flow channel 223 is also provided in the piston block 22, and the water inlet of the second flow channel 223 is connected to the side of the chamber 222 away from the first flow channel 221. The above-mentioned cleaning component 3 is arranged in the second flow channel 223. When the push plate 41 moves toward the second flow channel 223, the push plate 41 pushes the pressure transmission medium into the second flow channel 223 and applies pressure to the cleaning component 3.

[0037] With this design, when the valve body 1 is blocked, the fluid medium enters the chamber 222 through the first flow channel 221. As the fluid medium continues to be input, the fluid medium drives the push plate 41 to move in the chamber 222 away from the first flow channel 221. At this time, the second elastic unit 42 is compressed, and the pressure transmission medium is squeezed by the push plate 41 into the second flow channel 223 and applies pressure to the cleaning component 3, so that the cleaning component 3 cleans the impurities blocked between the partition plate 11 and the piston block 22. When the impurities are cleaned, the flow channel in the valve body 1, the pressure of the fluid medium and the liquid level all begin to decrease. At this time, the second elastic unit 42 stretches and drives the push plate 41 to move toward the first flow channel 221. The fluid medium in the chamber 222 is pushed out of the chamber 222 and returns to the valve body 1 through the first flow channel 221, and the pressure transmission medium flows back to the chamber 222.

[0038] Preferably, the pressure transmission medium can be water, hydraulic oil, etc.

[0039] Preferably, the second elastic unit 42 can be a spring in the prior art.

[0040] In one embodiment, the second flow channel 223 is divided into a main channel 2231, a first branch channel 2232, and a second branch channel 2233. The first branch channel 2232 is opened in the direction aligned with the space between the partition plate 11 and the piston block 22, and the second branch channel 2233 is opened in the direction aligned with the side of the piston block 22 close to the water outlet of the valve body 1.

[0041] The cleaning component 3 includes a first cleaning plate 31 slidably arranged in the first branch channel 2232 and a second cleaning plate 32 vertically slidably arranged in the second branch channel 2233. The first cleaning plate 31 is composed of a first pushing end 311 dynamically sealed in the first branch channel 2232 and a first cleaning end 312 connected to the first pushing end 311. The first cleaning end 312 is arranged in the valve body 1 along the length direction of the partition plate 11. The second cleaning plate 32 is composed of a second pushing end 321 dynamically sealed in the second branch channel 2233 and a second cleaning end 322 connected to the second pushing end 321. The second cleaning end 322 is arranged in the valve body 1 along the length direction of the partition plate 11. The longitudinal section of the second cleaning end 322 is triangular and aligned with the side of the piston block 22 close to the water outlet of the valve body 1. It also includes a reset component 33 arranged in the second flow channel 223. The reset component 33 is used to drive the first cleaning plate 31 and the second cleaning plate 32 to move away from the partition plate 11.

[0042] With this design, when the valve body 1 is blocked, the pressure transmission medium is squeezed by the push plate 41 into the main channel 2231 of the second flow channel 223 and is divided into the first branch channel 2232 and the second branch channel 2233. As the fluid medium continues to apply a thrust to the push plate 41 away from the first flow channel 221, the pressure transmission medium squeezes the first pushing end 311 to move toward the direction close to the partition plate 11, the first cleaning end 312 contacts the impurities and applies a thrust toward the direction close to the partition plate 11, the pressure transmission medium also squeezes the second pushing end 321 to move downward, the second cleaning end 322 contacts the corresponding impurities and applies a vertical downward thrust until the impurities blocked between the partition plate 11 and the piston block 22 are pushed out, the pressure of the fluid medium decreases along the passage of the flow channel of the valve body 1, and the reset member 33 drives the first cleaning plate 31 and the second cleaning plate 32 to move away from the partition plate 11 and squeeze the pressure transmission medium in the second flow channel 223, thereby causing the pressure transmission medium to flow back to the chamber 222.

[0043] In one embodiment, the reset member 33 includes a third elastic unit 331 arranged in the first branch channel 2232 and a fourth elastic unit 332 arranged in the second branch channel 2233, and one end of the third elastic unit 331 is connected to the outlet of the first branch channel 2232, and the other end is connected to the first cleaning end 312, and one end of the fourth elastic unit 332 is connected to the outlet of the second branch channel 2233, and the other end is connected to the second cleaning end 322. The third elastic unit 331 and the fourth elastic unit 332 are respectively used to drive the first cleaning plate 31 and the second cleaning plate 32 to move away from the partition plate 11.

[0044] With this design, when the pressure transmission medium enters the second flow channel 223 and squeezes the first cleaning plate 31 and the second cleaning plate 32, the third elastic unit 331 and the fourth elastic unit 332 are compressed. When the impurities blocked between the partition plate 11 and the piston block 22 are pushed out, the pressure of the fluid medium in the chamber 222 drops, and the third elastic unit 331 and the fourth elastic unit 332 respectively drive the first cleaning plate 31 and the second cleaning plate 32 to move away from the partition plate 11. The first cleaning plate 31 and the second cleaning plate 32 squeeze the pressure transmission medium from the second flow channel 223 back into the chamber 222.

[0045] Preferably, the third elastic unit 331 and the fourth elastic unit 332 can be springs in the prior art.

[0046] In one embodiment, a groove 224 is formed on the bottom surface of the piston block 22;

[0047] A scraping component 5 is also provided in the valve body 1, which includes a scraping plate 51 rotatably arranged at the top of the partition plate 11 close to the water inlet of the valve body 1, and the top of the scraping plate 51 extends out of the inclined surface of the partition plate 11 and is arranged below the groove 224. A torsion spring (not shown in the figure) is provided at the rotating connection between the scraping plate 51 and the partition plate 11. The torsion spring provides a torsional force for the scraping plate 51 to rotate upward. When the first cleaning plate 31 contracts, the first cleaning end 312 contacts the top surface of the scraping plate 51.

[0048] With this design, when the first cleaning plate 31 pushes the impurities toward the scraping plate 51, the impurities come into contact with the scraping plate 51 and cause the scraping plate 51 to rotate downward toward the water inlet of the valve body 1. The first cleaning plate 31 continues to exert thrust on the impurities until the impurities leave the partition plate 11. At this time, the impurities no longer contact the scraping plate 51, the torsion spring loses its constraint and drives the scraping plate 51 to rotate upward until the top surface of the scraping plate 51 contacts the first cleaning end 312. The first cleaning plate 31 contracts along the flow path of the valve body 1, and the first cleaning plate 31 contracts. During the contraction of the first cleaning plate 31, the top surface of the scraper plate 51 contacts the first cleaning end 312 and scrapes away impurities attached to the end of the first cleaning end 312, preventing the impurities attached to the end of the first cleaning end 312 from moving with the first cleaning end 312, thereby preventing the first cleaning plate 31 from carrying impurities to block the valve body 1 again when it contracts. When the flow channel of the valve body 1 is closed, the piston block 22 descends and contacts the partition plate 11. At this time, the top end of the scraper plate 51 is inserted in the groove 224 and will not affect the closing of the flow channel of the valve body 1.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
