A foreign body prevention cover

Abstract

The invention relates to a foreign matter preventing cover, which is detachably arranged on the air port of the inflow part that sucks in external air, so as to block the inflow of foreign matter. An air pipe and a supply pipe, the air pipe constitutes an external pipe body and is provided with a vent port, the supply pipe constitutes an internal pipe body and one side of the upper part is formed with a supply port; and a connecting part, which is a double pipe body, includes a drain An air pipe and a connecting pipe, one end of the exhaust pipe is connected to the ventilation pipe, the other end is closed, and a region of the bottom surface is provided with an exhaust port, the connecting pipe constitutes an internal pipe body, and one end of the exhaust pipe is connected to the supply pipe Connect the other end to the air port.

Description

technical field [0001] The present invention relates to a preventive cover, and more particularly, to a foreign matter preventive cover provided on equipment that sucks in outside air, such as canisters for vehicles, outdoor air ducts, ventilation fans, and snorkeling etc., so that air can flow into the interior, and block foreign matter other than air such as moisture and insects from flowing into the interior. Background technique [0002] Generally, devices that suck in external air, such as tanks for vehicles, outdoor air ducts, ventilation fans, and submersible snorkels, etc., suck air through the inflow part of the suction air, and install a cover to prevent the inflow of foreign matter on the suction part. [0003] Although such a preventive cap is provided on various devices as described above, the description of a conventional preventive cap in the present invention is based on a preventive cap provided on a can. [0004] A conventional anti-corrosion cover is disc...

Problems solved by technology

[0010] Therefore, when the vehicle passes quickly on the waterlogged surface, there is a problem of water flowing through the curved pipe and into the inside of the tank through the air port

[0011] In addition, when insects (for example, spiders, etc.) invade the inside of the tank through the bent tube and through the air port and inhabit there, the space between the bent tube and the stepped protrusion is blocked and eventually the fuel tank linked with the tank may be damaged. Deformation or damage due to systolic pressure

[0012] As mentioned above, the space between the existing curved pipe and the stepped protrusion has limitations in blocking the foreign matter flowing in through the air port, and in some cases, the foreign matter flows in and not only causes a decrease in function, but also damages the vehicle due to clogging. Causing serious damage (e.g. breakage of fuel tanks, etc.)
