Pneumatic flapping and air exhausting spraying self-cleaning type air filter

Abstract

The invention discloses a pneumatic flapping and air exhausting spraying self-cleaning type air filter applicable to an automobile engine. The pneumatic flapping and air exhausting spraying self-cleaning type air filter comprises a filter element, a control device and a spraying and flapping dedusting device, wherein the spraying and flapping dedusting device is arranged on the filter element in a matched mode and connected between a pre-filter / an upper-level filtering unit and an engine body / a lower-level filtering unit of the automobile engine; and the control device is connected to the spraying and flapping dedusting device and used for controlling the spraying and flapping dedusting device. According to the scheme, the defects that the dedusting difficulty is large, time and labor are wasted, and the maintenance cost is high in the prior art can be overcome, and the beneficial effects that dust is convenient to remove, time and labor are saved and the maintenance cost is low are achieved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a self-cleaning air filter of a pneumatic flapping and diffused air injection, in particular to a pneumatic flapping and diffused air injection self-cleaning air filter. Background technique [0002] At present, most of the air filters of automobile engines use paper filters. There are many ways to maintain and remove paper filter elements, such as holding high-pressure gas at a 45-degree angle to remove dust in the paper filter. In this method, the filter element of the paper filter must be removed from the car, and the dust particles embedded in the depth of the filter medium cannot be cleaned out. It is inevitable that the filter element will fail early due to dust embedding, which will increase the fuel consumption of the engine. Thereby, the work of the engine is time-consuming and laborious, and the replacement cycle of the filter element is shortened, requi...

Problems solved by technology

In this method, the filter element of the paper filter must be removed from the car, and the dust particles embedded in the depth of the filter medium cannot be cleaned out. It is inevitable that the filter element will fail early due to dust embedding, which will increase the fuel consumption of the engine.

As a result, the work of the engine is time-consuming and laborious, and the replacement cycle of the filter element is shortened, requiring frequent replacement of new filter elements

[0003] In the prior art, there are defects such as difficult dust removal, time-consuming and labor-intensive, and high maintenance costs
