Car air filter

Abstract

The invention discloses a car air filter which comprises an upper end cover, a lower end cover and a filter element. The lower end cover and the upper end cover are connected in a clamping mode. The filter element is placed between the upper end cover and the lower end cover. A circular boss, a water draining plate and a dust discharging valve are arranged on the lower end cover. The edge of the circular boss and the edge of the dust discharging valve are connected. The water draining plate comprises a first water draining plate, a second water draining plate and a third water draining plate. The bottom end of the filter element is connected with the top ends of the first water draining plate, the second water draining plate and the third water draining plate. According to the car air filter, the first water draining plate, the second water draining plate and the third water draining plate are added on the lower end cover, the filter element and the lower end cover are separated through the water draining plate, a certain space is formed, and accordingly accumulated water in the filter element can be drained smoothly. Through the improved structure, convenience of filter element replacing and air filter maintaining can be guaranteed, the service life of the filter element can be prolonged, and the filtering performance of the air filter is improved.

Description

technical field [0001] The invention relates to the technical field of automobile engine auxiliary parts, in particular to an automobile air filter. Background technique [0002] The automobile engine needs to inhale a large amount of air during the working process. 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. Larger particles enter between the piston and the cylinder, which will cause serious "squeeze the cylinder", which is especially serious in the dry and sandy working environment. The air filter is installed in front of the carburetor or the intake pipe to filter out dust and sand particles in the air to ensure sufficient and clean air entering the cylinder. [0003] In actual use, the air filter has a great impact on the service life of the car engine. On the one hand, if there is no filtering effect of the air filter, the engine will inhale a large amo...

Problems solved by technology

like figure 1 As shown, when installed vertically, the filter element 101 in the air filter is compressed by the upper end cover 102 and the lower end cover 103 of the air filter, and the bottom of the filter element 101 is in direct contact with the lower end cover 103. When the rainwater and moisture in the air enter the air filter to produce waste water, due to the surface tension of the water, the water at the contact between the bottom of the filter element 101 and the lower end cover 103 cannot be completely discharged, causing the filter element 101 to be in a wet state from time to time. Thereby reducing the service life of the filter element 101, affecting the filtering performance of the air filter, and in extreme cases, the engine will be damaged due to untimely filtering
