Air filter for automobile

Abstract

The invention belongs to the technical field of air filters, and particularly relates to an air filter for an automobile. The air filter comprises an upper cover, a lower shell, a main air inlet, a main air outlet, a sealing ring and a filter element; the upper cover and the lower shell are combined with each other; the lower end of one side of the lower shell is communicated with the main air inlet, and the upper end of the other side is communicated with the main air outlet; the sealing ring and the filter element are placed in the lower shell; one end of a driving motor is fixedly connected with the lower shell, and the other end of the driving motor is rotationally connected with a screw rod; the other end of the screw rod is rotationally connected with the lower shell; the screw rod and the driving motor are positioned on one side of the filter element; a polished rod is located on the other side of the filter element; the screw rod is sleeved with a first sliding block; the polished rod is sleeved with a second sliding block; the two ends of a connecting block are fixedly connected with the first sliding block and the second sliding block correspondingly; the two sides of the lower shell are each provided with a first sliding groove; and a dust accumulation box is in sliding connection with the lower shell through the first sliding groove. According to the air filter, the problem that too much dust is accumulated on the filter element and is forgotten to be removed, so that the work of the air filter is affected is solved.

Description

technical field [0001] The invention belongs to the technical field of air filters, in particular to an air filter for automobiles. Background technique [0002] Generally, vehicles generate power by mixing fuel and air and burning the mixture of fuel and air, that is, fuel stored in the fuel tank of the vehicle passes through various types of fuel supply devices, is mixed with air introduced from the outside, and then injected into the cylinders of the engine while the engine operates through repeated intake, compression, combustion and exhaust strokes, whereby the vehicle gains power. [0003] The air filter is an important component of the car, which is used to filter the dust and impurities contained in the air sucked by the engine, so as to reduce the early wear and tear of the cylinder, piston, piston ring, valve and valve seat; the existing air filter is usually composed of upper and lower shells body and a filter element located inside the shell; the upper and lower...
