Air intake filter device for automobile engine

Abstract

The invention belongs to the technical field of engine air intake filtration, and particularly relates to an automobile engine air intake filter device, which includes an air intake end, an air outlet end, and a filter structure. The surface of the half of the filter structure corresponding to the intake pipe will form a dirty blockage. At this time, the drive motor is controlled to work, and the drive motor drives the filter structure to rotate 180 degrees, so that the half of the filter structure that is not blocked and polluted is rotated to align with the intake pipe at the intake end The filtering work is carried out at the matching position, and the half filter structure originally located in alignment with the intake pipe is guided by the swing plate, so that after the gas entering through the intake pipe is filtered by the upper part of the filter structure, some of the gas flows smoothly. The first semi-circular channel at the air outlet flows into the second semi-circular channel, and then the drainage of the second semi-circular channel blows and cleans the lower half of the filter structure, which increases the number of uses of the filter structure and reduces the cost of use.

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
