Supercharged air filter auxiliary device for vehicle engine

Abstract

The invention discloses a supercharged air filter auxiliary device for a vehicle engine, which includes an air pipe communicating with an intake end of the vehicle engine, wherein an inner wall of theair pipe is rotationally connected with a filter screen; the filter screen is provided with a blower at a side close to the engine; the two sides of the filter screen are provided with an air returnpipe and an air guide pipe respectively that are abutted against the two sides; the air return pipe and the air guide pipe are fixed to the inner wall of the air pipe; the air guide pipe is a straightpipe having two communicating ends; the air return pipe is a bent pipe having one end in contact with the filter screen; the end of the air return pipe away from the filter screen is in communicationwith a side pipe; the side pipe communicates with the air pipe; the communication position of the side pipe and the air pipe is located on the air outlet side of the blower; and the air return pipe is opposite to the corresponding air guide pipe. The supercharged air filter auxiliary device has advantages that when the blower pumps air, the filter screen produces a preliminary filtering effect onthe pumped air, making the air entering the air filter body relatively cleaner, reducing the working load of the air filter body and extending its service life.

Description

technical field [0001] The invention relates to the technical field of vehicle engine air intake, in particular to a vehicle engine supercharged air filter aid. Background technique [0002] The car air filter is mainly responsible for removing particulate impurities in the air. When the piston machine is in motion, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter is composed of a filter element and a housing. The air filter will inevitably accumulate a large amount of impurities during long-term continuous use. However, in the prior art, it is difficult to disassemble and clean the air filter after it is installed inside the vehicle. Therefore, it can only be replaced in time after the air filter has been used for a period of time, and the economy is poor. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art, and ...
