The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a fully automatic water filter with a floating scraper, including a water filter tank 1, a connecting mechanism 4, and a floating scraping mechanism 5. A tank cover 2 is fixedly installed on one side of the water filter tank 1. The connecting mechanism 4 is located inside the water filter tank 1 and includes a rotating block 401 and a polygonal block 403. The inner wall of the rotating block 401 is in contact with but not connected to the outer wall of the polygonal block 403. The floating scraping mechanism 5 is located inside the water filter tank 1 and includes a mounting rod 501, a hollow sleeve rod 502, a movable rod 503, and a cleaning brush 505. The outer wall of the mounting rod 501 is fixedly connected to one end of multiple sets of hollow sleeve rods 502. The inner wall of the filter tank 2 is slidably connected to the outer wall of a set of movable rods 503. One end of the movable rod 503 extends to the outside of the hollow sleeve rod 502 and is fixedly installed with a cleaning brush 505. A reduction motor 3 is fixedly installed on one side of the tank cover 2. The output shaft of the reduction motor 3 is fixedly connected to the rotating block 401. Two sets of annular baffles 6 are fixedly installed on the inner wall of the filter tank 1. A cylindrical filter screen 7 is fixedly installed on the adjacent side of the two sets of annular baffles 6. A water pipe 8 is fixedly installed on the outer wall of the filter tank 1. A drain pipe 9 is fixedly installed on the outer wall of the filter tank 1. The drain pipe 9 is located between the two sets of annular baffles 6. A sewage pipe 10 is fixedly installed on the outer wall of the filter tank 1. The sewage pipe 10 is located on one side of the two sets of annular baffles 6.

[0023] Secondly, the connecting mechanism 4 also includes a threaded rod 402 and a positioning hole 404. A rotating block 401 is rotatably installed on one side of the inner wall of the can cover 2. The outer wall of the rotating block 401 is threadedly connected to the threaded rod 402. A positioning hole 404 is opened on the front side of the polygonal block 403. One end of the threaded rod 402 passes through the interior of the positioning hole 404, which enables the floating scraping mechanism 5 to be quickly disassembled and installed. This makes it easy for staff to remove and replace the damaged cleaning brush 505. The operation is simple and easy to use, which improves the usability and practicality of the device.

[0024] Furthermore, the floating scraping mechanism 5 also includes a spring 504. One side of the polygonal block 403 is fixedly connected to one end of the mounting rod 501. A set of springs 504 are fixedly installed on the other end of the hollow sleeve rod 502. One end of the spring 504 is fixedly connected to the adjacent side of the cleaning brush 505. The movable rod 503 passes through the interior of the spring 504 but is not connected. Through the elastic support of the spring 504, the cleaning brush 505 is always in contact with the curved surface or uneven parts of the cylindrical filter screen 7 to perform floating brushing on the cylindrical filter screen 7, so as to avoid cleaning dead corners as much as possible, making the brushing force of the cleaning brush 505 more uniform, ensuring the cleaning effect of the cylindrical filter screen 7, and reducing the probability of damage to the cylindrical filter screen 7.

[0025] Working principle: When using this device, connect the external water pipe to the water pipe 8, and pour the water to be filtered into the water filter tank 1 from below. The water passes through the cylindrical filter screen 7, filtering out impurities. The filtered water is then discharged through the drain pipe 9, while wastewater is discharged through the sewage pipe 10. After a period of use, turn on the reduction motor 3 to drive the rotating block 401 to rotate, which in turn drives the mounting rod 501 to rotate. Under the elastic action of the spring 504, the movable rod 503 automatically extends and retracts within the hollow sleeve rod 502, allowing... The cleaning brush 505 floats and brushes the inner wall of the cylindrical filter screen 7 to remove the impurities adhering to the cylindrical filter screen 7. The impurities are discharged through the water pipe 8. When the cleaning brush 505 needs to be replaced, remove the can cover 2 from the water filter tank 1, take the cleaning brush 505 out of the water filter tank 1, rotate the threaded rod 402 to move it on the rotating block 401, move the threaded rod 402 out of the positioning hole 404, remove the limit on the polygonal block 403, and then remove the polygonal block 403 from the rotating block 401. The same method is used for installation.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
