Automobile engine air intake filtering device

Abstract

The invention belongs to the technical field of engine air intake filtering and particularly relates to an automobile engine air intake filtering device. The automobile engine air intake filtering device comprises an air inlet end, an air outlet end and a filtering structure. According to the filtering device, after the filtering structure is used for a long time, dirt blocking can be formed on the surface of the half part, exactly facing an air inlet pipe of the air inlet end, of the filtering structure, a driving motor is controlled to work at the time and drives the filtering structure to rotate by 180 degrees, the not blocked and polluted half part of the filtering structure is rotated to the position in aligned fit with the air inlet pipe of the air inlet end to carry out filtering work, and for the half part, originally in aligned fit with the air inlet pipe, of the filtering structure, through guiding of a swing plate, air entering through the air inlet pipe is filtered by the upper half part of the filtering structure, a part of gas flows into a second semicircular channel along a first semicircular channel of the air outlet end, then the lower half part of the filtering structure is blown and cleaned through drainage of the second semicircular channel, the using times of the filtering structure is increased, and the use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of engine intake air filtration, and in particular relates to an automobile engine intake air filter device. Background technique [0002] With the development of society, cars are becoming more and more common in life, and the air conditioner filter of most vehicles is located in the filter box next to the engine. [0003] If the traditional filter works in windy and sandy weather for a long time, it will cause the surface of the filter to become dirty, reduce the filtration efficiency and increase the wind resistance of the system, thus affecting the ventilation performance of the system, and the air filter element needs to be cleaned and replaced in time. [0004] In the process of long-distance driving, for the sake of convenience and cost saving, after driving for a period of time and feeling that the ventilation performance of the filter is reduced, the filter element in the filter is generally removed...

AI Technical Summary

Problems solved by technology

[0003] If the traditional filter works in windy and sandy weather for a long time, it will cause the surface of the filter to become dirty, reduce the filtration efficiency and increase the wind resistance of the system, which will affect the ventilation performance of the system. It is necessary to clean and replace the air filter element in time

[0004] In the process of long-distance driving, for the sake of convenience and cost saving, after driving for a period of time and feeling that the ventilation performance of the filter is reduced, the filter element in the filter is generally removed, and the filter element is blown clean by a blower before use to extend the use However, the disassembly and assembly of the filter element body on the market is very inconvenient, and when cleaning and replacing the filter element, it is necessary to unscrew the screws to disassemble the filter box and other complicated processes, especially for drivers with poor hands-on ability, there are filter removal, cleaning, The defect of inconvenient installation; so it is very necessary to design an air filter that can reduce the number of replacements
