Description

Technical Field

[0001] The utility model belongs to the technical field of gasoline engines, and particularly relates to a gasoline engine housing vent cover installation structure. Background Art

[0002] The vents on the casing of a gasoline engine are all connected to ventilating covers, which not only provide ventilation but also help prevent dust. Currently, the vent covers on the market are all flat structures, which causes them to be too close to the heating part of the engine. The vent covers are usually made of plastic, and high heat can easily cause the vent covers to soften, affecting their service life. In addition, the vent covers need to be frequently disassembled for cleaning or internal inspection. Currently, most vent covers use a snap-on structure, and multiple disassembly can easily cause the snaps to be damaged. Utility Model Content

[0003] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a gasoline engine housing vent cover installation structure to solve the problems raised by the above background technology.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A gasoline engine housing vent cover installation structure includes a window arranged on the gasoline engine housing and a breathable cover. The breathable cover and the window are detachably connected to the window via a magnetic connection structure. After the breathable cover is installed, the outer wall of the breathable cover bulges outward to form a convex surface higher than the surface of the gasoline engine housing.

[0006] Preferably, the bottom of the breathable cover is snap-connected to the bottom edge of the window, a strong magnet is fixed on the inner side of the top of the breathable cover, and correspondingly, a magnetic attraction portion is provided near the top edge of the window. During installation, the bottom of the breathable cover is snap-connected to the window, and the strong magnet on the top of the breathable cover is magnetically connected to the magnetic attraction portion.

[0007] Preferably, a buckle is integrally formed at the bottom of the ventilating cover, and a slot is provided near the bottom edge of the window. When snapping, the buckle is snapped into the slot.

[0008] Preferably, a strong magnet is connected to the inner side of the top of the breathable cover by ultrasonic welding, and the magnetic attraction part is a screw fixedly connected to the edge of the window.

[0009] Preferably, a ventilation groove is provided on the outer wall of the ventilation cover.

[0010] In summary, the utility model mainly has the following beneficial effects:

[0011] The present application has a window clip connection at the bottom of the vent cover, combined with a magnetic connection structure at the top, which is more convenient for disassembly. In addition, the vent cover protrudes from the surface of the gasoline engine casing, which is farther away from the heat source, thereby increasing the service life of the vent cover.
