A hose 525 is rotatably connected to one end of the spray pipe 52 through a bearing and is fixedly connected to the other end of the spray pipe 52 through a bearing.

[0050] The driving member 53 comprises an outer gear 531 and a toothed plate 532. The outer gear 531 is fixedly installed on the spray pipe 52, and the toothed plate 532 is fixedly installed in the purification bin 2. The outer gear 531 is in meshing connection with the toothed plate 532. A reciprocating screw rod 533 is rotatably connected in the guide rail groove 522 through a bearing. A sliding block 534 is fixedly connected to the bottom of the guide rail block 523 and is threadedly assembled on the reciprocating screw rod 533.

[0052] Example three:

[0053] The difference from the above-mentioned example two is that, referring to Figures 1-11 For the above-mentioned sundry filtering area 61, the sundry filtering area 61 is fixedly installed outside the purification bin 2. A passageway 11 is arranged between the sundry filtering area 61 and the purification bin 2. A carrying member 12 is arranged in the passageway 11. An activity filter plate 13 is arranged between the purification bin 2 and the filtering bin 3. The filter hole of the activity filter plate 13 is located at the top of the oil mist collecting area 62. One end of the activity filter plate 13 is hingedly connected with the inner wall of the purification bin 2. A torsional spring 14 is arranged at the hinge connection between the activity filter plate 13 and the inner wall of the purification bin 2.

When the liquid passes through the filter hole, the solid impurities in the liquid are filtered and left near the movable filter plate 13 and the channel opening 11. The arrangement that the top ends of the two movable rotating plates 121 in the carrying piece 12 are in contact with the top and bottom surfaces of the channel opening 11 prevents a large amount of liquid from flowing into the garbage filtering area 61. The second motor 129 drives the rotating roller 122 to rotate, thereby driving the movable rotating plate 121 to rotate. The arrangement of the movable rotating plate 121 carries the solid garbage near the channel opening 11 into the garbage filtering area 61. When the movable rotating plate 121 rotates, it is in contact with the movable filter plate 13. The arrangement that the movable filter plate 13 is hinged to the inner wall of the purification bin 2 and the torsional spring 14 drives the movable filter plate 13 to vibrate during the rotation of the movable rotating plate 121, thereby carrying the solid impurities on the top of the movable filter plate 13 to the vicinity of the channel opening 11 and then carrying the solid garbage into the garbage filtering area 61 through the movable rotating plate 121. During the rotation of the movable rotating plate 121, part of the liquid flows into the garbage filtering area 61. The arrangement that the garbage filtering area 61 is in communication with the oil mist collecting area 62 and the communication part is provided with the filter screen 16 and the inclined arrangement of the filtering channel 15 cause the liquid in the garbage filtering area 61 to flow into the oil mist collecting area 62.
