AI Technical Summary
Existing air filters are difficult to clean effectively in dusty environments, as they accumulate dust and impurities at the bottom, making cleaning challenging.
A self-cleaning air filter was designed. By starting a motor to drive a rotating mechanism, the impact mechanism repeatedly impacts the hollow cylinder, reducing the adhesion of dust and causing it to detach from the inner wall for easy cleaning.
This allows dust to be effectively removed from the inner wall and bottom of the hollow cylinder, simplifying the cleaning process and improving the maintenance efficiency of the air filter.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of air filtration technology, and in particular to a self-cleaning air filter. Background Technology
[0002] Air filters play a crucial role in car engines, filtering air, engine oil, and fuel to ensure proper engine operation and extend engine life. The primary function of the air filter is to remove solid impurities such as dust and sand, as well as gaseous pollutants like water, soot, smoke, ozone, odors, and carbon oxides, ensuring that the air entering the engine is sufficient and clean. This helps reduce wear on cylinders, pistons, piston rings, valves, and valve seats, extending engine life and increasing engine power. When compressed air enters the air filter through the inlet, impurities and air are separated within the filter. Heavier impurities such as dust, moisture, and oil accumulate at the bottom of the air filter, while lighter air passes through the filter element and exits through the outlet. After several filtrations, the bottom of the air filter becomes clogged with impurities, which are then expelled through the outlet at the bottom of the air filter. Currently, when a car is in a dusty environment, a large amount of dust and a small amount of water accumulate at the bottom of the air filter, making it difficult to clean properly. Therefore, improvements are urgently needed. Utility Model Content

The third rotating rod drives the U-shaped block to reciprocate on the fixed block, which in turn drives the impact rod to reciprocate. The impact rod then drives the impact cylindrical plate to reciprocate, repeatedly impacting the hollow cylinder. This repeated impact of the impact cylindrical plate on the hollow cylinder reduces the adhesion of dust to the hollow cylinder, allowing dust to detach from the inner wall and bottom of the hollow cylinder, facilitating subsequent cleaning.
