带有挡片的空滤器

Air filter with blocking piece

Abstract

The invention provides an air filter with a blocking piece. The air filter comprises an air filter lower shell and the blocking piece, wherein a water leakage hole and a clamping hole are formed in the air filter lower shell; the blocking piece is fixed to the bottom surface of the air filter lower shell; the blocking piece comprises a bearing plate, a cantilever and a center plate; the bearing plate is fixedly connected with the center plate by virtue of the cantilever; a clamping column is arranged on the center plate; and a set clearance is formed between the bearing plate and the bottom surface of the air filter lower shell, the water leakage hole is shielded by the bearing plate, and the clamping column is matched with the clamping hole. According to the air filter with the blocking piece, the blocking piece is fixedly clamped on the air filter lower shell, so that when the weather is fine, the water leakage hole is shielded by the blocking piece, hot air is prevented from entering the air filter, and certain sealing performance of the air filter is guaranteed so as not to influence the noise reduction performance; when the weather is rainy, rainwater enters the air filter, and after a certain amount of water is stored in the air filter, the bearing plate is automatically opened to drain water under the action of gravity of the water, so that the problem of the prior art is solved, and the noise reduction performance of the air filter is improved.
本发明提供了一种带有挡片的空滤器,其中,包括:空滤器下壳体,其上开设有漏水孔和卡孔;挡片,固定在空滤器下壳体的底面;挡片包括承压板、悬臂和中心板;承压板通过悬臂与中心板固定连接;中心板上设置有卡接柱;承压板与空滤器下壳体的底面之间具有设定的间隙,且承压板遮挡漏水孔,卡接柱与卡孔卡接配合。本发明提供的带有挡片的空滤器,通过设置挡片卡接固定在空滤器下壳体上,天晴时,挡片遮挡漏水孔,阻止了热空气进入空滤器,也保证了空滤器一定的密封性而不影响降噪性能;下雨时,空滤器进入雨水,空滤器内部储存一定的水量后,在水的重力作用下,承压板会自动打开而排水,从而解决了现有技术中的问题,并提高了空滤器的降噪性能。
