Combined air filter

Abstract

The invention discloses a combined air filter comprising a shell and an electrostatic dust suction device, wherein a filter screen cylinder is arranged in the shell; a corona electrode with a raised structure and a dust collecting electrode are arranged at the periphery of the shell; and air is effectively filtered through roughly filtering dust-containing air by using the filter screen cylinder and finely filtering the dust-containing air by using the electrostatic dust suction device in the air suction process. The combined air filter is compact and reasonable in structural design; the filter screen cylinder can be used for roughly filtering air and repeatedly cleaning and using the air; and due to the arrangement of the electrostatic dust suction device, the dust collecting effect is improved, meanwhile, the air inlet resistance is reduced, the performance of an engine is improved, the service life of the filter is prolonged, and the filtering efficiency is increased.

Description

technical field [0001] The invention relates to the field of automotive filters, in particular to a combined air filter. Background technique [0002] When the car is running, the surrounding air contains a lot of dust, most of which are small particles with high hardness such as silicon oxide, iron oxide and aluminum oxide. If the particles enter the engine cylinder, valve and piston, etc., these parts will be damaged quickly. Wear and tear, or even scrapped, so an air filter is needed to filter the air entering the cylinder. Conventional air filters generally use multi-stage filter elements to filter the air. On the one hand, this increases the air intake resistance of the engine and affects the normal operation of the engine. On the other hand, the filter holes in the dusty working environment It can easily become clogged and cause engine failure or damage. Therefore, the conventional air filter has the disadvantages of short service life, frequent dismantling and clean...

Problems solved by technology

Conventional air filters generally use multi-stage filter elements to filter the air. On the one hand, this increases the intake resistance of the engine and affects the normal operation of the engine. On the other hand, the filter holes in the dusty working environment Can easily get clogged and can cause engine failure or damage

Therefore, the conventional air filter has the disadvantages of short service life, frequent dismantling and cleaning or replacement of the filter element, and low filtering effect.
