When the filter is used, a person skilled in the art flows the oil filtering liquid into the partition plate 34 through the oil filling hole 12, after the oil filtering liquid flows into the inner wall of the bottom end of the filter box 1 through the conveying structure 17, the oil filtering liquid I23 is formed after the oil filtering liquid I23 flows into the inner wall of the bottom end of the filter box 1, the oil filtering liquid is left on the partition plate 34 through the conveying structure 17, the amount of the oil filtering liquid I23 and the oil filtering liquid II 33 is not required to be determined, after the oil filtering liquid I23 and the oil filtering liquid II 33 are formed, the reciprocating lead screw II 4311 and the screw II 4321 are rotated through the driving structure 41, after the rotation, the reciprocating lead screw II 4321 drives the reciprocating lead screw I4211 and the screw I4221 to rotate through the transmission structure 44, the first reflection plate 22 is lifted through the first sliding block 4212 until the bottom end of the first reflection plate 22 is positioned on the inner wall of the top end of the oil filtering liquid I23, after that, the first reciprocating lead screw 4211 and the first screw 4221 are not rotated through the transmission structure 44, and then the second rotating reciprocating lead screw 4311 can lift the second reflection plate 32 through the second sliding block 4312 until the bottom end of the second reflection plate 32 is positioned on the inner wall of the top end of the second oil filtering liquid 33;

when the oil filter needs to be used, gas flows into the first hollow pipe 21 through the gas inlet pipe 111 through external equipment, after the gas flows into the first hollow pipe 21, the gas flows into the first reflecting plate 22 through the first hollow pipe 21, after the gas flows into the first oil filtering liquid 23 through the first reflecting plate 22, the gas flowing into the first oil filtering liquid 23 can flow upwards, the gas flowing upwards can flow into the second reflecting plate 32 through the second hollow pipe 31, after the gas flows into the first reflecting plate 32, the gas can flow into the second oil filtering liquid 33 through the second reflecting plate 32, the gas can be filtered for the second time, the filtered gas can be exhausted through the exhaust pipe 15, and the gas can be filtered;

after filtration, the first screw 4221 and the second screw 4321 are rotated forwardly and reversely by the driving structure 41 and the transmission structure 44, the first screw 4221 and the second screw 4321 respectively drive the first circular plate 4222 and the second circular plate 4322 to lift through the first nut 4225 and the second nut 4325, the first lifted circular plate 4222 and the second circular plate 4322 respectively clean the first hollow pipe 21 and the second hollow pipe 31 through the first brush wire 4223 and the second brush wire 4324, wherein when gas passes through the first hollow pipe 21 and the second hollow pipe 31, part of impurities in the gas can remain in the first hollow pipe 21 and the second hollow pipe 31.

While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the various features of the disclosed embodiments of the invention may be used in any combination, provided that no structural conflict exists, and the combinations are not exhaustively described in this specification merely for the sake of brevity and resource conservation.
