The rack 18 is meshed with the gear 17, a waste port 14 is provided at the bottom center of the cylinder bottom 2, a valve body 15 is provided at the waste port 14 of the cylinder bottom 2, a one-way valve and a solenoid valve are provided in each water inlet hole 7 and water outlet hole 8, the solenoid valves in all water inlet holes 7 are connected in series through wires and are electrically connected to an external power supply, the solenoid valves in all water outlet holes 8 are connected in series through wires and are electrically connected to an external power supply, the solenoid valves are opened when power is on and closed when power is off, the one-way valve at the water inlet hole 7 only allows water to flow into the annular cavity 3, and the one-way valve at the water outlet hole 8 only allows water to flow out of the annular cavity 3.

[0025] Reference Figure 3-7 The auxiliary cleaning mechanism includes an L-shaped bracket 19, which is fixed on the base 9. The upper end of the rotating sleeve 4 is fixedly connected to two symmetrically distributed fixed plates 20, and the upper ends of the two fixed plates 20 are fixedly connected to the bottom surface of the upper end of the bracket 19. The inner wall of the rotating sleeve 4 is slidably connected to a lifting plate 22, and a filter screen 23 is fixedly connected to the lifting plate 22. The rotating sleeve 4 is provided with two symmetrically distributed slide grooves 21, and each of the two ends of the lifting plate 22 is fixedly connected to a slider 24, and the two sliders 24 are slidably connected to the two slide grooves 21 respectively.

[0026] A guide groove 26 is provided on the inner wall of the cleaning cylinder 1. A sliding ball 25 is fixedly connected to each side of the two sliders 24 away from the lifting plate 22. The two sliding balls 25 are slidably connected to the guide groove 26 on the cleaning cylinder 1. The shape of the guide groove 26 is as follows: Figure 6 As shown, the two sliding balls 25 are connected end to end and symmetrically distributed, so that the two sliding balls 25 are always at the same height in the guide groove 26, a magnetic plate is embedded in the lifting plate 22, and a magnetic annular plate 27 is sealed and slidably connected in the annular cavity 3. The magnetism of the annular plate 27 is attracted to the magnetism of the magnetic plate embedded in the lifting plate 22, and a plurality of liquid flow holes 28 are opened on the annular plate 27 at equal intervals. A plurality of air inlet holes 29 are opened on the top of the cleaning cylinder 1 to communicate with the annular cavity 3, and a one-way valve is arranged in each liquid flow hole 28 and the air inlet hole 29. The one-way valve in the liquid flow hole 28 only allows liquid or gas to flow from the top of the annular plate 27 to the bottom, and the one-way valve in the air inlet hole 29 only allows gas to flow from the outside to the annular cavity 3.

[0027] When the device is in use, the electromagnetic valve of the water inlet 7 is first closed, and the electromagnetic valve of the water outlet 8 is powered on and opened, and then water is injected into the cleaning cylinder 1, and then the material to be cleaned is put into the cleaning cylinder 1, and then the motor 16 is turned on, and the motor 16 drives the gear 17 to rotate. Through the meshing transmission of the gear 17 and the annular rack 18, the entire cleaning cylinder 1 rotates around the annular groove 11 on the base 9. The rotation of the cleaning cylinder 1 causes the water inside to generate a vortex to wash the material. Since the rotating sleeve 4 is in a fixed state, when the cleaning cylinder 1 rotates, the two sliding balls 2 5 will slide along the guide groove 26 on the inner cylinder wall, thereby driving the entire lifting plate 22 to move up and down, stirring the materials in the cleaning cylinder 1, and improving the cleaning efficiency of the materials. At the same time, the magnetic plate embedded in the lifting plate 22 will drive the annular plate 27 in the annular cavity 3 to slide together through the magnetic attraction when moving. Under the action of the one-way valve, the outside air will be sucked into the annular cavity 3 through the air inlet 29, and then the compressed air of the annular plate 27 will be ejected from the multiple water outlets 8 and emerge at the bottom of the cleaning cylinder 1 in the form of bubbles, thereby increasing the turning of the materials and improving the cleaning effect.

[0028] After the cleaning is completed, when the control motor 16 stops, the two sliding balls 25 are just at the highest position of the guide groove 26, so that the lifting plate 22 rises to the highest position to filter and fish out the cleaned materials from the cleaning cylinder 1, which is convenient for the staff to pick up. After the materials are fished out, the solenoid valve of the water outlet 8 is closed, and the solenoid valve at the water inlet 7 is opened. The motor 16 is turned on again to drive the water in the cleaning cylinder 1 to rotate, and a vortex is formed under the action of centrifugal force. At this time, the reverse osmosis membrane 6 on the rotating sleeve 4 will separate the water from other substances in the water under the action of centrifugal force and water pressure. The water will pass through the reverse osmosis membrane 6 to the side of the inner cylinder wall, and enter from multiple water inlet holes 7 as the cleaning cylinder 1 rotates. In the annular cavity 3, after the cleaning cylinder 1 rotates for several circles, the clean water in the cleaning cylinder 1 will be separated and stored in the annular cavity 3, and the small amount of sewage remaining at the bottom of the cleaning cylinder 1 can be discharged by opening the valve body 15 at the bottom of the cylinder bottom 2, and then the valve body 15 is closed to open the solenoid valve at the water outlet 8, and the water in the annular cavity 3 enters the cleaning cylinder 1 for recycling, avoiding the waste of water resources and reducing production costs. The staff can also inject disinfectant into the annular cavity 3 through the air inlet 29, which can be used for cleaning of special objects and disinfection in the annular cavity 3. After multiple water circulations, the disinfectant in the annular cavity 3 will be flushed clean and will not affect subsequent use.
