The main air inlet holes 2 are arranged in at least two rows on the side wall of the oil filter screen body 1, the main air inlet holes on each row are uniformly distributed at intervals, and the main air inlet holes 2 on the adjacent rows are distributed in a staggered manner in the horizontal direction. The inner cavity wall of the oil filter screen body 1 is taken as an inner wall, the bottom of the main air inlet hole 2 is provided with a main oil receiving tongue 21 protruding towards the inner cavity direction of the oil filter screen body 1, and the free end of the main oil receiving tongue 21 extends obliquely upwards.
The auxiliary air inlet holes 3 are arranged below the main air inlet holes 2, and the auxiliary air inlet holes 3 are in a strip shape and are transversely distributed at intervals at the lower part of the peripheral wall of the oil filter screen body 1. In this embodiment, the auxiliary air inlet holes 3 are divided into two rows, i.e., upper and lower, and the auxiliary air inlet holes 3 in different rows are distributed in a staggered manner in the horizontal direction. In addition, the bottom of the auxiliary air inlet 3 is provided with an auxiliary oil receiving tongue 31 protruding toward the inner wall of the oil filter screen body 1, and the free end of the auxiliary oil receiving tongue 31 extends obliquely upward.
The oil filter screen is bent upward at the bottom periphery of the oil filter screen body 1 to form an oil sump 4, and an oil drain hole (not shown) is formed in the bottom of the oil sump 4. The oil collecting groove 4 and the oil filter screen body 1 of the embodiment are integrally formed, and a special oil collecting groove is not required to be additionally arranged, so that the structure is simple, the cost is reduced, the cleaning difficulty of a user is reduced, and the user experience is improved.
