The inner left side of the operating frame 2 is rotatably connected to a rotating plate 6, and the outer side of the fixed column 4 is fixedly connected to a gear 1 7. The fixed column 4 will drive the gear 1 7 to rotate while rotating, and one side of the rotating plate 6 is rotatably connected to a gear 2 8. The external teeth of the gear 1 7 are meshed with the external teeth of the gear 2 8. When the gear 1 7 rotates, the external teeth will drive the gear 2 8 to rotate, and the external teeth of the gear 2 8 are meshed with the internal teeth of the rotating plate 6. At the same time, as the gear 2 8 rotates, the rotating plate 6 will be driven to rotate, thereby realizing the rotation adjustment of the brush 5. Since the diameters of the fixed column 4 and the gear 2 8 are different, the rotation speeds are different, and the steel mesh can be cleaned more comprehensively.

[0028] Reference Figure 4-5The upper and lower sides of the interior of the box body 1 are fixedly connected with sliding rods 9, and the outer side of the sliding rod 9 is slidably connected with a fixing frame 10. When the fixing frame 10 is pulled outward, the fixing frame 10 will extend outward along the trajectory of the sliding rod 9, and the steel mesh will be stuffed into the interior of the fixing frame 10. The fixing frame 10 is provided with limiting components on both sides of the front, back, upper and lower sides. The limiting components include limiting grooves 11, springs 12, limiting plates 13 and connecting columns 14. When in contact, the connecting columns 14 will be squeezed to both sides. The limiting grooves 11 are opened in the interior of the fixing frame 10, and the springs 12 are arranged in the interior of the limiting grooves 11. The outer side of the limiting plate 13 is slidably connected to the interior of the limiting grooves 11, so that the limiting plate 13 slides in the interior of the limiting grooves 11, and the springs 12 are arranged in the interior of the limiting grooves 11. The spring 12 is compressed under force, and due to its own elastic characteristics, it absorbs external force and generates a reaction force on the limit plate 13 when compressed. One end of the spring 12 is fixedly connected to one side of the limit groove 11, and the other end of the spring 12 is fixedly connected to the other side of the limit plate 13.

[0029] Reference Figure 5-6 The front end of the box body 1 is rotatably connected with a box door 16, and a sliding groove 17 is provided on the right side of the interior of the box door 16. The interior of the sliding groove 17 is slidably connected with a card column 18. As the connecting plate 19 rotates, the card column 18 will be driven to slide outward in the interior of the sliding groove 17. The front end of the card column 18 is rotatably connected with the connecting plate 19. When the connecting plate 19 is rotated outward, a spring 20 is sleeved on the outside of the card column 18. While the card column 18 slides, the spring 20 is squeezed so that the spring 20 is compressed. One end of the spring 20 is fixedly connected to the outside of the card column 18, and the other end of the spring 20 is fixedly connected to the inside of the sliding groove 17. A card slot 21 is provided at the front end of the box body 1, and the rear end of the card column 18 is engaged with the inner wall of the card slot 21. At this time, the card column 18 is separated from the card slot 21, and the box door 16 can be opened, thereby fixing the box door 16, ensuring the sealing effect, and facilitating subsequent drying.

[0030] Working principle: First, rotate the connecting plate 19 outward. As the connecting plate 19 rotates, the card column 18 will slide outward inside the sliding groove 17. While the card column 18 slides, it squeezes the spring 20, so that the spring 20 is compressed. At this time, the card column 18 is separated from the card groove 21, and the box door 16 can be opened. Then, pull the fixing frame 10 outward, and the fixing frame 10 will extend outward along the trajectory of the slide rod 9, and the steel mesh will be inserted into the inside of the fixing frame 10. The steel mesh contacts the rubber ball 15, and while contacting, it will squeeze the connecting column 14 on both sides, so that the limit plate 13 slides inside the limit groove 11. At the same time, the spring 12 is compressed. Due to its own elastic characteristics, it absorbs external force when compressed and 3 generates a reaction force, and then pushes the fixing frame 10 into the interior of the box body 1, and then closes the box door 16 again, turns on the water pump, draws water from the water tank through the water pump, and then uses the nozzle to spray the water onto the steel mesh, and then starts the motor 3 at the same time. The fixing column 4 rotates under the drive of the motor 3. At this time, the brush 5 will clean the steel mesh with the rotation of the fixing column 4. The fixing column 4 will drive the gear 1 7 to rotate while rotating. The external teeth of the gear 1 7 will drive the gear 2 8 to rotate while rotating. At the same time, the rotation of the gear 2 8 will drive the rotating plate 6 to rotate. Since the diameters of the gear 1 7 and the gear 2 8 are different, the rotation speeds are different, so the steel mesh can be cleaned more comprehensively.
