Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] As Figure 1 - Figure 5 As shown, the present invention provides a technical solution: an anti-blocking valve, including a pipeline 1, the outer side of the middle end of the pipeline 1 is fixedly connected with a valve body 11, and the outer side of one end of the pipeline 1 is fixedly connected with a water outlet 12. One end of the pipeline 1 far from the water outlet 12 is fixedly connected with a filter box 13, and the middle end of the side of the filter box 13 far from the pipeline 1 is fixedly connected with a water inlet 14. A sealing component is inserted in the middle end of the filter box 13, and a filtering component is fixedly connected to the middle end of the sealing component. A striking component is fixedly connected to the inner side of one end of the filter box 13 close to the pipeline 1, and plug pin components are rotatably connected to both sides of the upper end of the sealing component. A clamping position component is arranged on the outer side of one end of the plug pin component far from the sealing component. During use, after the sealing component drives the filtering component to be inserted into the filter box 13 for clamping, the plug pin component is inserted into the clamping position component for installation. During the use process, when filtering through the filtering component, the filtering component can also be intermittently struck by the striking component, so as to slow down the blocking frequency of the filtering component, effectively extend the blocking duration, thereby reducing the cleaning frequency, and at the same time improving the convenience of cleaning and disassembly.

[0022] As Figure 2 As shown, the sealing component includes a cover plate 2 inserted in the inner side of the upper end of the filter box 13, and a sealing gasket 21 is fixedly connected to the lower side of the cover plate 2. A frame 22 is fixedly connected to the lower end of the sealing gasket 21, and first plug boards 23 are fixedly connected to both ends of the frame 22. One end of the first plug board 23 far from the frame 22 is inserted into the filter box 13, and the upper end of the filter box 13 is sealed by the cover plate 2 and the sealing gasket 21.

[0023] As Figure 4As shown, the filter assembly includes a filter screen 3 inserted on the inner side of the middle end of the frame 22, and the two ends of the filter screen 3 are fixedly connected to a limit plate 31, the end of the limit plate 31 away from the filter screen 3 is inserted in the frame 22, and a first spring 32 is fixedly connected to the outer side of the middle end of the limit plate 31, and the end of the first spring 32 away from the limit plate 31 is fixedly connected to the frame 22. Water flows into the filter box 13 from the water inlet 14 and is filtered by the filter screen 3. When the water flow impacts the filter screen 3, the filter screen 3 drives the limit plate 31 to move and compress the first spring 32, so as to filter impurities in the water flow.

[0024] like Figure 3 As shown, the striking assembly includes an electric telescopic rod 4 fixedly connected to the inner side of one end of the filter box 13 near the pipe 1, and the output shaft of the electric telescopic rod 4 is fixedly connected to a striking block 41. The electric telescopic rod 4 is started, and the electric telescopic rod 4 is driven to drive the striking block 41 to push and strike the filter 3, thereby vibrating the filter 3, and the impurities filtered out from the upper end of the filter 3 fall to the lower end of the filter box 13 for storage, so that the impurities attached to the outer side of the filter 3 can be shaken off by the operation of the electric telescopic rod 4.

[0025] like Figure 5 As shown, the latch assembly includes a rotating plate 5 rotatably connected to the outer sides of the two ends of the cover plate 2, and a second plug plate 51 is fixedly connected to the end of the rotating plate 5 away from the cover plate 2. The rotating plates 5 at both ends are rotated to allow the rotating plates 5 to drive the second plug plate 51 to be inserted into the locking assembly, so as to facilitate the fixing of the cover plate 2.

[0026] like Figure 5 As shown, the locking assembly includes a shell 6 which is sleeved on the outer side of one end of the second plug plate 51 away from the rotating plate 5, and one end of the shell 6 close to the filter box 13 is fixedly connected to the filter box 13, a locking plate 61 is inserted inside the lower end of the shell 6, and the upper end of the locking plate 61 is inserted in the second plug plate 51, a second spring 62 is fixedly connected to the lower end of the locking plate 61, and one end of the second spring 62 away from the locking plate 61 is fixedly connected to the shell 6, a slider 63 is fixedly connected to the outer side of the lower end of the locking plate 61, and the end of the slider 63 away from the locking plate 61 is inserted and slides in the shell 6, and one end of the locking plate 61 away from the slider 63 is fixedly connected to a push plate 64, push the push plate 64, let the push plate 64 pull the locking plate 61 to move and compress the second spring 62 with the assistance of the slider 63, so that the locking plate 61 is pulled out of the second plug plate 51, and then the rotating plate 5 is toggled to drive the second plug plate 51 to be pulled out of the shell 6, so as to facilitate the locking of the second plug plate 51 and the subsequent quick removal.

[0027] Working principle: when the valve is installed and used, first the cover plate 2 drives the sealing gasket 21 and the frame 22 to be inserted into the filter box 13, and then the rotating plates 5 at both ends are rotated to allow the rotating plates 5 to drive the second plug plate 51 to be inserted into the shell 6. When the second plug plate 51 is inserted, the card plate 61 is squeezed, and the card plate 61 is moved and compressed with the assistance of the slider 63 to compress the second spring 62. Then the second plug plate 51 continues to be inserted. When the second plug plate 51 is inserted, the second spring 62 pushes the card plate 61 to pop out, and the card plate 61 is inserted into the second plug plate 51 for fixing. When the valve body 11 is opened, water flows into the filter box 13 from the water inlet 14 and is filtered by the filter screen 3. The filtered water enters the pipe 1 and is discharged from the water outlet 12, while the filtered impurities remain on the outside of the filter screen 3. When the water flows impact the filter screen 3, the filter screen 3 drives the limit plate 31 to move and compress the first spring 32. When the filter screen 3 has filtered the water flow for a period of time, the electric telescopic rod 4 can be started, and the electric telescopic rod 4 can be operated to drive the striking block 41 to push and strike the filter screen 3, thereby causing the filter screen 3 to vibrate and the impurities filtered out from the upper end of the filter screen 3 to fall to the lower end of the filter box 13 for storage. When the filter screen 3 needs to be taken out for cleaning later, the push plate 64 is pushed, and the push plate 64 pulls the card plate 61 to move and compress the second spring 62 with the assistance of the slider 63, so that the card plate 61 is pulled out of the second plug plate 51, and then the rotating plate 5 is toggled to drive the second plug plate 51 to be pulled out of the shell 6, and then the push plate 64 is released, and the rotating plate 5 is pulled, and the rotating plate 5 is pulled to pull the cover plate 2 to move, so that the cover plate 2 drives the sealing gasket 21 and the frame 22 to drive the filter screen 3 to be pulled out of the filter box 13 for cleaning, and then the impurities stored in the filter box 13 are cleaned, and the cleaned filter screen 3 is inserted into the filter box 13 for installation.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
