Referring to fig. 2 and 3, a first oil return groove 21 and a second oil return groove 22 are formed in the bottom of the lower housing 2, the first filter structure 3 is located in the first oil return groove 21, and the second filter structure 4 is located in the second oil return groove 22.

The first filter structure 3 includes a limiting portion 11 provided on the upper case 1, and a partition plate 5 installed on the limiting portion 11. The bottom of the lower shell 2 is provided with an air inlet 23 at one side of the partition plate 5, the partition plate 5 is provided with a U-shaped part 51, a space is reserved between the U-shaped part 51 and the top of the upper shell 1, the upper shell 1 is provided with a baffle part 52 in the middle of the U-shaped part 51, the bottom of the U-shaped part 51 is obliquely arranged, an oil leakage hole 53 is arranged at the lower end, and the limiting parts 11 limit the positions of two sides of the partition plate 5. The structure of the partition 5 can be further illustrated with reference to fig. 4. The top of the partition 5 is fixed to the top of the upper case 1 by the elastic cord 7, and the stopper 11 keeps the partition 5 vibrating in the up-down position. The structure of the limiting part 11 is a plurality of bumps or raised strips protruding from the inner wall of the upper shell 1, so that the limiting part 11 can partially limit the movement of the partition board 5. In the structure of this embodiment, after the spacing portion 11 has limited the partition board 5, the partition board 5 can only move up and down, and due to the gravity of the partition board 5 itself and the function of the elastic cord 7, the partition board can float up and down under the actual working condition.

Second filtration 4 includes first filter 41 and second filter 42, and first filter 41 is vertical to be sheltered from and sets up a plurality of gas posts 411 on vertical face, and the tip of gas post 411 is provided with a plurality of nose cone bodies 421 towards the second filter 42 of vertical setting on the second filter 42, and the bottom of second oil gallery 22 sets up to stair structure 25 and sets up the oil return at the lowest and chews 26.

On the basis, as can be seen from fig. 4, the oil leakage hole 53 is provided with the filter screen 6, and the filter screen 6 is arranged to further isolate impurities.
