[0050] When cleaning the surface of the filter plate 103, the hook spring 301 can be clamped with the handle 4. Since the other end of the hook spring 301 is fixedly connected to the movable rod 3, rotating the handle 4 can drive the movable rod 3 to slide on the inner wall of the sleeve 201. During the sliding process, the movable rod 3 drives the scraper bar 105 to move. When the scraper bar 105 moves to a position close to the limit block 110, the scraper bar 105 rotates around the limit block 110 as the center to scrape. During the rotation of the scraper bar 105, the pull rope 106 connected thereto is stretched. When the pull rope 106 is stretched, the movable plate 107 fixedly connected to the pull rope 106 rotates. When the scraper bar 105 is close to the discharge port 109, the movable plate 107 rotates downward to discharge the filtered impurities outward. When the scraper bar 105 is reset, the movable plate 107 rotates upward and abuts against the baffle 108, which can slow down the overflow of raw water.

The sleeve 201 connected to the outer surface of the feed barrel 102 allows the limiting rod 2 to slide with the piston rod.

[0053] The end of the limit rod 2 away from the filter plate 103 is fixedly connected to the movable rod 3, which is slidably connected to the inner wall of the sleeve 201, and the other end is fixedly connected to the hook spring 301. The other end of the hook spring 301 is fixedly connected to the handle 1 4, and the other end of the handle 1 4 is hinged to the fixed rod 401. The outer surface of the fixed rod 401 is fixedly connected to the handle 2 402, and the other end of the handle 2 402 abuts against the purification barrel 1.

[0054] The hook spring 301 is used to connect the handle 4 and the movable rod 3. When the handle 4 and the movable rod 3 are connected through the hook spring 301, the handle 4 is rotated. The handle 4 drives the hook spring 301 to stretch during the rotation. The hook spring 301 drives the movable rod 3 to slide on the inner wall of the sleeve 201 during the stretching process. The sliding of the movable rod 3 drives the cleaning device to clean the surface of the filter plate 103.

[0055] The outer surface of the fixed rod 401 is slidably connected with a slider 5, and the slider 5 is fixedly connected with a clamping block 501 near the fixed rod 401. The clamping block 501 is clamped with a clamping groove 502, and the clamping groove 502 is set on the handle 1 4 near the slider 5.

[0056] The slider 5 slidably connected to the outer surface of the fixed rod 401 can slide on the fixed rod 401. When the slider 5 slides, the block 501 fixedly connected to its side engages with the groove 502 on the handle 1 4. After the engagement is completed, the handle 1 4 is fixedly connected to the handle 2 402. Then, the handle 2 402 can be rotated by pulling the handle 1 4, thereby achieving purification of the device.

[0057] The other end of the handle 2 402 is fixedly connected with a filter head 6, the lower surface of the filter head 6 is fixedly connected with a membrane filter 601, and the outer surface of the membrane filter 601 is sleeved with a filter tube 602. A hinge 7 is provided between the filter head 6 and the handle 2 402, the lower end of the hinge 7 is fixedly connected with a piston 1 701 and a piston 2 702, and the side of the handle 2 402 is fixedly connected with an anti-collision pad 703. There are two filter heads 6, namely, filter head A8 and filter head B801. The inner surface of the filter head A8 is provided with a valve plate 1 802 and a valve plate 2 803, and the inner surface of the filter head B801 is provided with a valve plate 3 804 and a valve plate 4 805. The inner surface of the filter head A8 is provided with a cavity 1 9, and the inner surface of the filter head B801 is provided with a cavity 2 901. The upper surfaces of the filter head A8 and the filter head B801 are slidably connected with piston 1 701 and piston 2 702 respectively.

Since the other end of the hook spring 301 is fixedly connected to the movable rod 3, the handle 4 can be turned to drive the movable rod 3 to slide on the inner wall of the sleeve 201. During the sliding process, the movable rod 3 drives the scraper bar 105 to move. When the scraper bar 105 moves to a position close to the limit block 110, the scraper bar 105 rotates with the limit block 110 as the center to scrape. During the rotation of the scraper bar 105, the pull rope 106 connected thereto is stretched. When the pull rope 106 is stretched, the movable plate 107 fixedly connected to the pull rope 106 rotates. When the scraper bar 105 is close to the discharge port 109, the movable plate 107 rotates downward to discharge the filtered impurities outward.
