[0019] The cleaning component includes a driving plate 7 sleeved on the surface of the filter element metal mesh 10, a threaded rod 13 passes through the interior of the driving plate 7 and is threadedly connected to the threaded rod 13, and when the threaded rod 13 rotates, it drives the threaded driving plate 7 to move, and the limiting column 12 passes through the interior of the driving plate 7 and is slidably connected to the driving plate 7. The limiting column 12 cooperates with the threaded rod 13 to limit the position of the driving plate 7 to prevent the driving plate 7 from rotating and tilting when moving, thereby improving the stability of the driving plate 7 when moving, and rotating the annular brush plate 8 installed inside the driving plate 7 through the bearing. The inner side of the annular brush plate 8 is tightly attached to the surface of the filter element metal mesh 10, and when the driving plate 7 moves, it drives the rotating connected annular brush plate 8 to move. When the annular brush plate 8 moves, it brushes the surface of the filter element metal mesh 10 through one side that is tightly attached to the surface of the filter element metal mesh 10, thereby brushing particulate matter and debris off the surface of the filter element metal mesh 10, and the annular brush plate A guide hole is provided inside 8, and two groups of guide holes are symmetrically provided inside the annular brush plate 8, and are fixed to the guide column 9 inside the pre-filter 2.

Two groups of guide columns 9 are symmetrically fixed inside the pre-filter 2, and both groups of guide columns 9 are slidably connected with the annular brush plate 8 through the guide holes. When the driving plate 7 drives the annular brush plate 8 to move, the guide holes provided inside the annular brush plate 8 will slide along the surface of the guide column 9, so that the guide holes drive the annular brush plate 8 to move, so that when the driving plate 7 drives the annular brush plate 8 to move, the annular brush plate 8 itself can rotate through the guide column 9 and the guide hole, so that the annular brush plate 8 can improve the efficiency of brushing the surface of the filter element metal mesh 10 by rotating while brushing the surface of the filter element metal mesh 10 while moving, thereby improving the effect of the annular brush plate 8 on the surface of the filter element metal mesh 10.

[0020] Working principle: when it is necessary to treat the wastewater of the washing machine 1, the water pump 4 can generate negative pressure to pump out the sewage inside the washing machine 1, and make the sewage flow through the pre-filter 2 and the filter device 3, and the water filtered by the pre-filter 2 and the filter device 3 is pumped into the water storage tank 5 for storage, so as to complete the purification and recycling of the wastewater of the washing machine 1, and reduce the waste of water resources. At the same time, when the filter element metal mesh 10 inside the pre-filter 2 is blocked by particles and debris in the wastewater after long-term use, resulting in a decrease in water purification efficiency, the threaded rod 13 can be driven by the driving motor 6 to rotate, so that the threaded rod 13 drives the driving plate 7 to move, and the driving plate 7 moves When the annular brush plate 8 is moved, the annular brush plate 8 can brush the surface of the filter element metal mesh 10 when it moves. At the same time, the annular brush plate 8 can rotate itself through the guide column 9 when it moves to rotate and brush the surface of the filter element metal mesh 10, so that the surface of the filter element metal mesh 10 is cleaned by the annular brush plate 8, reducing or avoiding the filter element metal mesh 10 being blocked by particles and debris in the wastewater during use, resulting in a decrease in water purification efficiency. It is relatively convenient to use. After brushing is completed, the large particles and debris brushed inside the pre-filter 2 can be discharged through the drain outlet 11. There is no need for manual cleaning by personnel, which reduces personnel labor and is relatively convenient to use.
