7. The oil-gas separation device of claim 6, wherein the fuel return port is provided in a bottom wall of the housing;
the free end of the first separation plate or the second separation plate extends towards the bottom wall of the oil-gas separation piece.
8. The oil-gas separation device according to claim 6, wherein the check valve is an electric check valve, and the oil-gas separation member further comprises a liquid level detector disposed in the filter chamber and electrically connected to the check valve.
9. The oil-gas separation device according to claim 6, wherein the check valve is a pneumatic check valve, and the pneumatic check valve is turned on when the air pressure in the engine is lower than the air pressure in the filter.
10. A vehicle, characterized by comprising an oil-gas separation device according to any one of claims 1-9.
