The upper and lower ends of the fixing frame 415 are internally provided with a tightening spring 416, and the upper and lower sides of the fixing frame 415 are internally slidably connected with a limiting disc 417, and the side of the limiting disc 417 away from the tightening spring 416 is fixedly connected with a sliding rod 418, and a cleaning brush 419 is fixedly connected between the two sliding rods 418 away from the side of the mounting sleeve 414.

One end of the tightening spring 416 is fixedly connected to the inside of the fixing frame 415, and the other end of the tightening spring 416 is fixedly connected to the side of the limiting disc 417 away from the cleaning brush 419.

Since the rotation of the impeller 402 can drive the hexagonal column 403 to rotate, it can drive the filter element 405 to rotate. After the filter element 405 rotates, it can drive the installation sleeve 414 to rotate. After the installation sleeve 414 rotates, it can drive the fixing frame 415 to rotate. After the fixing frame 415 rotates, it can drive the cleaning brush 419 to rotate through the sliding rod 418, and then the inner wall of the coarse filter barrel body 3 can be cleaned. When the coarse filter barrel body 3 and the filter element 405 are not to be cleaned, the automatic valve 1 407, the solenoid valve 12 and the solenoid valve 2 15 are opened, and the electric valve 411 is closed. At this time, after the water flow is connected to the connecting pipe 16, the water flow enters the automatic valve 1 407 and the interior of the rotating sleeve 404 through the splicing pipe 408, and then enters the interior of the filter element 405 through the rotating sleeve 404, and then can be filtered. At the same time, the water pump 10 is started, and the water flow enters the interior of the pre-filter 7 through the water pipe 11, and enters the interior of the water suction pipe 13 through the pre-filter 7, and then enters the interior of the high-pressure filter 9 through the liquid outlet pipe 14. When the pipeline is connected to the interior of the water outlet mechanism 6, the water flow in the high-pressure filter 9 can be discharged through the water outlet mechanism 6.

[0031] The splicing mechanism 5 includes a plurality of fixed blocks 501, which provide installation positions. The plurality of fixed blocks 501 are fixedly connected to the outside of the installation box 401. The top of the fixed block 501 is fixedly connected to a limiting column 502, which provides limiting conditions and installation positions. The outside of the fixed block 501 is rotatably connected to a trigger frame 503, and sliding grooves 504 are provided inside the two sides of the trigger frame 503.

The outer sleeve of the limiting column 502 is provided with a tension spring 506. The outer sliding connection of the limiting column 502 is a sliding sleeve 507, which can provide an installation position. The outer A hanging bracket 508 is rotatably connected, and the hanging bracket 508 slides inside the sliding groove 504, thereby preventing movement interference between the hanging bracket 508 and the trigger bracket 503. A plurality of hanging blocks 509 are fixedly connected to the top of the outer periphery of the coarse filter barrel body 3, and the hanging blocks 509 are engaged with the hanging bracket 508. The engagement of the hanging bracket 508 and the hanging blocks 509 can install the installation box 401 on the top of the coarse filter barrel body 3. One end of the tension spring 506 is fixedly connected to the bottom of the stabilizing block 505, and the other end of the tension spring 506 is fixedly connected to the top of the sliding sleeve 507. The two sides of the hanging bracket 508 are respectively slidably connected to the inside of the two sliding grooves 504, and the outside of the stabilizing block 505 is fixedly connected to the outside of the installation box 401 to install the fixed valve 401. When removing, the pulling frame 503 is first rotated downward, so that the hanging frame 508 and the sliding sleeve 507 can be driven to move downward, and then the tension spring 506 is stretched. When the hanging frame 508 is engaged with the bottom of the hanging block 509, the pulling frame 503 is released. At this time, the hanging frame 508 can be tightly engaged with the bottom of the hanging block 509 under the tension of the tension spring 506, so that the installation box 401 can be installed. When disassembling, the pulling frame 503 is pulled downward again, and then the hanging frame 508 can be disengaged from the hanging block 509, and the hanging frame 508 is rotated out of the range of the hanging block 509. At this time, the pulling frame 503 is released. Under the action of the tension spring 506, the sliding sleeve 507 can be pulled back to its original position, and then the installation box 401 can be removed from the top of the coarse filter barrel body 3.

[0032] The water outlet mechanism 6 includes a water outlet pipe 601, which can provide an installation position. One end of the water outlet pipe 601 is fixedly connected to the bottom of the high-pressure filter 9. A sealing ring 602 is fixedly connected inside the water outlet pipe 601. A sliding water-passing tray 603 is slidably connected inside the water outlet pipe 601. The sliding water-passing tray 603 can provide an installation position. A fixed column 604 is fixedly connected to the side of the sliding water-passing tray 603 close to the high-pressure filter 9. The fixed column 604 plays a connecting role. A sealing plug 605 is fixedly connected to the side of the fixed column 604 away from the sliding water-passing tray 603. The sealing plug 605 can be plugged into the inside of the sealing ring 602, thereby preventing the water flow inside the high-pressure filter 9 from flowing out of the inside of the high-pressure filter 9. A return spring 606 is arranged inside the water outlet pipe 601. The sealing plug 605 is arranged inside the sealing ring 602. One end of the return spring 606 is fixedly connected to the sliding water-passing tray 6 03, the other end of the return spring 606 is fixedly connected to the side of the sealing plug 605 close to the sliding water-passing disk 603, and the outer bottom end of the coarse filter barrel body 3 is fixedly connected with a drain pipe 17. When the pipeline is inserted into the water outlet pipe 601, it can drive the sliding water-passing disk 603 to move toward the inside of the water outlet pipe 601, and then drive the fixed column 604 and the sealing plug 605 to move toward the inside of the water outlet pipe 601, and then enable the sealing plug 605 to move away from the inside of the sealing ring 602, so that the water flow inside the high-pressure filter 9 can flow out of the inside of the water outlet pipe 601. When the pipeline leaves the inside of the water outlet pipe 601, the sliding water-passing disk 603 is reset under the action of the return spring 606, and then the fixed column 604 and the sealing plug 605 are reset, so that the sealing plug 605 can be blocked in the inside of the sealing ring 602 again, and then the water inside the high-pressure filter 9 can be prevented from flowing out.

[0033] Working principle: When in use, start the water pump 10, close the solenoid valve 12, the solenoid valve 2 15 and the automatic valve 1 407, and then connect the water source to the connecting pipe 16. After the water pump 10 is started, it can drive the water to flow quickly, thereby driving the impeller 402 to rotate, and at the same time open the electric valve 411, and then the water can enter the interior of the high-pressure water spray head 413 through the connecting pipe 412, and spray out through the high-pressure water spray head 413, and the water flow flushes the filter element 405. Since the rotation of the impeller 402 can drive the hexagonal column 403 to rotate, it can drive the filter element 405 to rotate. After the filter element 405 rotates, it can drive the installation sleeve 414 to rotate. After the installation sleeve 414 rotates, it can drive the fixing frame 415 to rotate. After the fixing frame 415 rotates, it can drive the cleaning through the sliding rod 418 The brush 419 rotates, and then the inner wall of the coarse filter barrel body 3 can be cleaned. When the coarse filter barrel body 3 and the filter element 405 are not to be cleaned, the automatic valve 1 407, the solenoid valve 12 and the solenoid valve 2 15 are opened, and the electric valve 411 is closed. At this time, after the water flow is connected to the connecting pipe 16, the water flow enters the automatic valve 1 407 and the interior of the rotating sleeve 404 through the splicing pipe 408, and then enters the interior of the filter element 405 through the rotating sleeve 404, and then can be filtered. At the same time, the water pump 10 is started, and the water flow enters the interior of the pre-filter 7 through the water pipe 11, and enters the interior of the water suction pipe 13 through the pre-filter 7, and then enters the interior of the high-pressure filter 9 through the liquid outlet pipe 14. When the pipeline is connected to the interior of the water outlet mechanism 6, the water flow in the high-pressure filter 9 can be discharged through the water outlet mechanism 6;

[0034] When installing the fixed valve 401, first rotate the trigger frame 503 downward, so as to drive the hanging frame 508 and the sliding sleeve 507 to move downward, and then stretch the tension spring 506. When the hanging frame 508 is engaged with the bottom of the hanging block 509, release the trigger frame 503. At this time, the hanging frame 508 can be tightly engaged with the bottom of the hanging block 509 under the tension of the tension spring 506, so that the installation box 401 can be installed. When removing, the trigger frame 503 is pulled downward again, so that the hanging frame 508 and the hanging block 509 can be disengaged, and the hanging frame 508 is rotated out of the range of the hanging block 509. At this time, release the trigger frame 503. Under the action of the tension spring 506, the sliding sleeve 507 can be pulled back to its original position, and then the installation box 401 can be removed from the top of the coarse filter barrel body 3;

[0035] When the pipe is inserted into the outlet pipe 601, it can drive the sliding water-passing plate 603 to move into the outlet pipe 601, and then drive the fixed column 604 and the sealing plug 605 to move into the outlet pipe 601, and then the sealing plug 605 can move away from the inside of the sealing ring 602, so that the water flow inside the high-pressure filter 9 can flow out of the outlet pipe 601. When the pipe leaves the outlet pipe 601, the sliding water-passing plate 603 is reset under the action of the reset spring 606, and then the fixed column 604 and the sealing plug 605 are reset, so that the sealing plug 605 can be blocked in the inside of the sealing ring 602 again, and then the water inside the high-pressure filter 9 can be prevented from flowing out.
