Air inlet structure of waterproof air filter

Abstract

The invention discloses an air inlet structure of a waterproof air filter. The air inlet structure comprises an air inlet pipe connected with an air filter body; and an air inlet end of the air inlet pipe is mounted on an air inlet grille. The air inlet structure is characterized in that the air inlet end is sealed at a position facing to a windward face; and an air inlet is arranged on a side face which is adjacent to the windward face. The air inlet structure provided by the invention has the following advantages that the air inlet structure provided by the invention is applicable to different automobile types, and has the advantages of simple structure and convenience in installation; the air inlet is arranged on the side face of the air inlet end to prevent the air inlet from entering water, so that a filter core keeps dry; the filtering property of the filter core is ensured; and the service life of the filter core is further improved. Meanwhile, the properties of an engine can be ensured. The air inlet is arranged on the side face of the air inlet end, so that the air inlet is further prevented from being impacted by an air speed, and the noise is reduced.

Description

technical field [0001] The invention relates to an air filter, in particular to an intake structure of a waterproof air filter. Background technique [0002] The air filter is an important part of the engine. It is used to filter the dust and sand in the air, ensure the quality of the air entering the cylinder, and prolong the service life of the engine. Existing air filter (see figure 1 ) includes an air intake pipe 1, an air filter body 2, and an air outlet pipe 3. The air intake end of the air intake pipe 1 is installed on the air intake grille, and an air inlet 11 is opened at a frontal windward position. During heavy rain and car washing, water droplets easily flow into the air filter body 2 from the air inlet 11, causing the filter element inside to absorb water, thereby increasing the air intake resistance, shortening the life of the filter element, and affecting the performance of the engine. When the vehicle speed is high, because the air inlet is directly facing ...
