Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-6, a respirator structure that oil strain is effectual for engine, including base plate 1, interior casing 2 is installed in the inside embedding of base plate 1, interior casing 2's a lateral wall top has run through and has seted up venthole 6, interior casing 2's a lateral wall surface is close to the position embedding of last venthole 6 and has installed rivet 8, it installs shell fragment 11 and limiting plate 13 to cup joint on the rivet 8, shell fragment 11 is located between interior casing 2 and the limiting plate 13, shell fragment 11 corresponds and laminates with the outer wall surface of interior casing 2 with the position of last venthole 6, the internal surface of base plate 1 is located interior casing 2 periphery and is equipped with sealed arch 7, the one end of limiting plate 13 is equipped with perk limit 12.

In the embodiment, the four corners of the substrate 1 are all provided with mounting holes 5 in a penetrating manner; one side surface of the substrate 1 is provided with a raised edge 4.

Specifically, be equipped with mounting hole 5 on the base plate 1, the external screw mounting of accessible sets up raised edge 4 and agrees with engine crankcase one end on engine crankcase one end, sets up sealed arch 7 in 1 inside base plate, and engine crankcase link surface is equipped with the recess that agrees with sealed arch 7, compares traditional respirator leakproofness stronger, avoids oil to leak.

In this embodiment, an outer casing 3 is fixedly mounted on one side surface of a substrate 1, and an inner casing 2 is located inside the outer casing 3; an exhaust hole 9 is formed in the top of one side wall of the outer shell 3 in a penetrating manner; the elastic sheet 11 is a copper elastic sheet.

Specifically, oil gas generated in the use process of the engine passes through the upper air outlet 6 and the lower oil return opening 10, when the oil gas passes through the upper air outlet 6, the elastic sheet 11 is bent under the oil gas pressure, so that the upper air outlet 6 can spray the oil gas, the oil gas is sprayed on the inner surface of the outer shell 3, the oil can fall along the inner wall of the outer shell 3, the gas is sprayed outwards along the exhaust hole 9, the falling oil passes through the lower oil return opening 10 and returns to the inside of the engine crankcase again, when the oil gas passes through the lower oil return opening 10, the gas enters the outer shell 3 and is discharged from the exhaust hole 9, the oil can be accumulated at the bottom of the outer shell 3 and then passes through the lower oil return opening 10 again and returns again, oil-gas separation is realized, an oil filtering effect is realized, the elastic sheet 11 has a good oil filtering effect, the elastic sheet 11 has elasticity, and can cover the upper air outlet 6 after the oil gas pressure is removed, and the air is prevented from entering the inside of the base plate 1.
