The embodiment of the invention provides a vehicle-mounted air filter and a self-cleaning method, the vehicle-mounted air filter comprises a shell, the shell is provided with a first air inlet pipe, a first air outlet pipe, a second air inlet pipe and a second air outlet pipe, and the inner wall of the shell is provided with a guide groove, so that clean inlet air flows along the guide groove; the filtering material is arranged in the shell; the first end of the air collecting pipe is connected with the second air inlet pipe, and the second end of the air collecting pipe is the same as the advancing direction of the vehicle. A second air inlet pipe and a second air outlet pipe are additionally arranged on a shell, meanwhile, a guide groove is formed in the shell, so that clean inlet air flows along the guide groove, a low-static-pressure area is formed on the outer side of a filter material, a first air outlet pipe is controlled to be communicated with the atmosphere, a high-static-pressure area is formed at the first air outlet pipe, and under the driving of pressure gradient, the clean inlet air can flow into the high-static-pressure area. Air in the first air outlet pipe is continuously sucked to the outer side of the filtering material and flows out from the second air outlet pipe to drive dust attached to the filtering material to flow out, so that self-cleaning of the filtering material is realized.
本说明书实施例提供一种车载空气过滤器及自清洁方法,包括:壳体,壳体上设置有第一进气管、第一出气管、第二进气管和第二出气管,壳体内壁开设有导向槽,以使得清洁进气沿着导向槽流动;过滤材料,过滤材料设置于壳体内;集风管,集风管第一端与第二进气管相连接,集风管第二端与车辆行进方向相同。通过在壳体上增设第二进气管和第二出气管,同时在壳体内部开设导向槽,以使得清洁进气沿着导向槽流动,在过滤材料外侧形成低静压区,通过控制第一出气管与大气相连通,第一出气管处形成高静压区,在压力梯度的驱使下,第一出气管中的空气不断被吸至过滤材料外侧,从第二出气管流出,带动过滤材料上附着的灰尘流出,实现对过滤材料的自清洁。
