Further, the inlet end of the accommodating cavity 11 is used for communicating with the oil, the filter element 20 is rotatably arranged in the accommodating cavity 11, so that the oil can enter the filter device 100 through the inlet end of the accommodating cavity 11, and then the oil entering the filter device 100 from the inlet end of the accommodating cavity 11 flows to the filter element 20, so that the filtering reliability of the filter element 20 on the oil entering the accommodating cavity 11 is ensured. The filter element 20 is rotatable in the accommodating cavity 11, and can separate oil in the accommodating cavity 11 from impurities under the action of centrifugal force so as to remove impurities in the oil. The filter element 20 extends axially within the receiving chamber 11 and may be used to direct filtered oil to an oil inlet of the oil pump 201 so that the oil pump 201 pumps the filtered oil into the engine.

Further, the cleaning blade 12 is disposed on the inner wall of the supporting member 10, so that the cleaning blade 12 can be stably and reliably positioned in the accommodating cavity 11, the cleaning blade 12 extends towards the filter member 20, and not only can the contact between the cleaning blade 12 and the surface of the filter member 20 be ensured, but also the contact between the cleaning blade 12 and the impurities on the surface of the filter member 20 can be ensured, under the rotation of the filter member 20, the dirt on the surface of the filter member 20 can be scraped by the blade, so that the dirt accumulated on the surface of the filter member 20 is prevented from blocking the dirt scraped on the filter member 20, and the fluid flowing in the accommodating cavity 11 can be prevented from bringing the scraped dirt back to the accommodating cavity 11 again, so as to reduce the filtering pressure of the filtering device 100.
