Preferably, the upper end of the inner blocking column is fixedly connected with a dustproof net cover. The dust-proof net cover allows the external air to be filtered before entering the fuel tank, reducing the possibility of the external air directly entering the fuel tank and thus polluting the lubricating oil in the fuel tank.

Preferably, a circle of inner flanges is horizontally fixed inwardly at the opening of the upper end of the inner blocking column. The inner flanging can further prevent the lubricating oil in the oil tank from splashing out, effectively reducing the use loss of lubricating oil.

Preferably, the outer cover body is provided with a ring of outer baffles extending downwards along the opening, and the height of the outer baffles is smaller than the length of the lower end of the inner blocking column protruding from the outer cover. The outer baffle can further prevent dust and debris from entering the fuel tank from the outside. The height of the outer baffle is less than the length of the lower end of the inner baffle protruding from the outer cover, so as to ensure that the air passage through which external air enters the fuel tank will not be blocked by the outer baffle.

Preferably, the outer surface of the outer cover is provided with several anti-slip indentations. The anti-skid concave makes it more convenient to remove the exhaust device when maintaining and maintaining the lubricating oil tank in the future without slipping.

Preferably, the anti-slip indentations are strip-shaped, the direction of the anti-slip indentations is the same as the axial direction of the outer cover, and the anti-slip indentations are linearly distributed along the circumferential direction of the outer cover. The shape is long and the direction is the same as the axial direction of the outer cover, which is convenient to adapt to the shape of human fingers and further facilitates the disassembly process of the exhaust device.

Preferably, the exhaust device is made of stainless steel. The exhaust device made of stainless steel is relatively strong and durable, and has good corrosion resistance and waterproof ability.

The utility model has the advantages that it can automatically balance the pressure difference inside and outside the oil tank, and is not easy to pollute the lubricating oil in the oil tank.
