Problems solved by technology

Existing air filter elements for vacuum pumps have the disadvantages of poor filtering effect and short service life. After a period of use, the accumulation of dust will greatly increase the air flow resistance, which will cause failure of the vacuum booster system, which not only increases maintenance costs, but also threatens Driver and Passenger Safety

Abstract

The invention discloses a vacuum pump air filter for an electric passenger car, and relates to the technical field of filters. The vacuum pump air filter for the electric passenger car mainly consistsof a shell, a filter element, a filter upper cover, a filter lower cover, a dust sucker, a first sealing piece, a second sealing piece and the like. The air filter is provided with a pre-filter device, so that the filter effect is greatly improved, solid particles in air entering the filter are greatly reduced, the dust accumulating speed on the outer surface of the filter element is greatly reduced, and smooth circulation of the air is guaranteed; a dust sucking device is mounted at the external of the filter element, so that the air circulation of the filter element is guaranteed, the lifeof the filter element is greatly prolonged, and the filter element is hardly replaced; and the first sealing piece and the second sealing piece are mounted among the upper cover, the shell and the filter element, so that the tightness between the upper cover and the shell and between the upper cover and the filter element is greatly improved, and the filter effect of the filter is guaranteed.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a vacuum pump air filter for electric passenger cars. Background technique [0002] An air filter is a device used to remove particulate impurities from the air. The air filter consists of two parts, the filter element and the housing. The main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. The vacuum pump is the main component of the vacuum booster system. The vacuum pump needs to filter the air entering the vacuum pump when it is in use. Existing air filter elements for vacuum pumps have the disadvantages of poor filtering effect and short service life. After a period of use, the accumulation of dust will greatly increase the air flow resistance, which will cause the failure of the vacuum booster system, which not only increases maintenance costs, but also threatens Driver and Passen...
