Air filter assembly

Abstract

The invention relates to an air filter assembly. The air filter assembly comprises a shell (1), a first impeller (22), a second impeller (23), a first rotating shaft (24), a first impeller cover (25),a second impeller cover (26), a filter element (2), a scraping blade (4) and a connecting pipe (27). The filter element (2) is rotatably connected with the shell (1), one end of the scraping blade (4) is connected with the shell (1), the other end of the scraping blade (4) is tightly attached to the peripheral wall of the filter element (2), a driving mechanism capable of driving the filter element (2) to rotate is arranged in the filter element (2), and a first air outlet (31) and a second air inlet (9) are communicated through a connecting pipe (27). The air filter assembly has the beneficial effects that on the basis of saving energy and protecting environment, in the use process, dust, sand dust and other dirt on the surface of the filter element can be cleaned and absorbed, the filter element is not prone to being stained, the air inlet amount of an engine is ensured, the engine can stably and normally work, and the service life of the filter element is greatly prolonged.

Description

technical field [0001] The invention relates to a filter, in particular to an air filter assembly. Background technique [0002] The air filter is mainly set in the engine intake system. It is an assembly composed of one or several clean air filter components. Its main function is to filter out harmful impurities in the air that will enter the cylinder to reduce the air intake of the cylinder. , Early wear of pistons, piston rings, valves and valve seats. At present, in order to ensure that the engine has sufficient air intake, existing vehicles such as automobiles generally communicate with the air inlet between the air filter and the air intake grille at the front end of the engine room of the vehicle, so that when the vehicle is running In this process, the air outside the vehicle can quickly enter the engine. However, due to the poor air quality in some parts of the country, especially in northern China, the air contains a large amount of dust and sand, so when the air...

AI Technical Summary

Problems solved by technology

Although the engine air filter with the above-mentioned structure can use the outside air of the vehicle to drive the second impeller to rotate while the vehicle is running, the second impeller drives the first impeller to rotate through the rotating shaft, so that the first impeller can filter the filter element. The air is quickly delivered to the engine, so that the air intake of the engine can still be guaranteed even when the filter element is dirty, so that the engine can work stably and normally without the need for the vehicle to provide additional power, which has the effect of energy saving and environmental protection, and to a certain extent The service life of the filter element has been shortened, but the actual extended service life of the filter element is very limited, and the problem of the filter element becoming dirty in a short period of time has not been fundamentally solved
