Water removal car air filter

Abstract

The invention discloses a water-removing automobile air filter, which comprises an annular support plate, an inner cylinder, a filter paper, a pressing ring, a casing, a one-way valve and an upper cover. The air in the air inlet flows from bottom to top through the pressure ring, so that the air entering the air inlet passes through the filter element from bottom to top under the action of the pressure ring, and the dust and sand mixed in the air are blocked by the filter paper outside the inner cylinder, and The water droplets contained in the air accumulate on the outside of the filter paper, and when they accumulate to a certain extent, they slide off the filter paper, and the water droplets that fall enter the lower part of the housing from the water removal port at the bottom of the support plate, and flow out from the one-way valve, effectively reducing the amount of water entering the engine. The moisture content of the air ensures the normal operation of the engine and prolongs the service life.

Description

technical field [0001] The invention relates to the technical field of automobile air filter devices, in particular to a dewatering type automobile air filter. Background technique [0002] The engine takes in a large amount of air during operation. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder, and larger particles will enter between the piston and the cylinder. It will cause a serious "squeeze" phenomenon, which is especially serious in a dry and sandy working environment. The air filter is installed in front of the intake pipe to filter out dust and sand particles in the air to ensure sufficient and clean air entering the cylinder. [0003] During the working process of the air filter, the piston of the engine returns to inhale, forming a negative pressure at the air inlet of the air filter, and the air enters the filter element under the action of atmospheri...

AI Technical Summary

Problems solved by technology

[0003] During the working process of the air filter, the piston of the engine returns to inhale, forming a negative pressure at the air inlet of the air filter, and the air enters the filter element under the action of atmospheric pressure to be filtered. Sand particles can be directly filtered by the filter element, but when the air humidity is high, or in rainy and snowy weather, water droplets and air are directly sucked into the air filter during the engine suction process, and the existing air filter can only filter dust Or sand, and water droplets will directly enter the engine cylinder with the air. The engine cylinder is in a high temperature state during operation. The water droplets that enter are easy to rust the cylinder block and directly shorten the service life of the engine.
