Description

Empty filter core, empty filter and vehicle

Technical Field

The utility model relates to an auto-parts technical field, concretely relates to empty filter core, empty filter and vehicle.

Background

The air filter is used as an intake air filtering system when the engine works in a combustion mode and is used for removing suspended particle impurities in fresh air sucked by the engine and providing clean fresh air for the engine. The structure of the air filter mainly comprises a dirty side of the air filter, a filter element of the air filter and a clean side of the air filter, wherein the filter element mainly has the function of filtering suspended particle impurities in fresh air.

Along with the increase of the driving mileage of an automobile, the accumulation of suspended particle impurities in the air filtered by the air filter element is increased on the dirty side of the air filter, wherein part of the filtered suspended particle impurities can be attached to the dirty side of the air filter element, so that the filtering efficiency of the air filter element is influenced, the air inflow of the air filter element is reduced, and the performance of an engine is influenced. At present, the effective improvement means is to regularly perform soot blowing maintenance on the filter element of the air filter or directly replace the filter element of the air filter in the specified maintenance period of the whole automobile, so that the maintenance cost of the whole automobile is increased, and the satisfaction degree of a customer to an automobile manufacturer is reduced.

At present, the surface area of the filter element of the air filter of the automobile is increased mainly by folding the non-woven fabric filter material into a wave shape. As disclosed in CN 204041295U an air cleaner structure for automobile engine, including the filter core, the filter core is located upper cover, the lower cover of mutual lock, and the filter core comprises non-woven fabrics folding core body and non-woven fabrics frame form limit layer, and non-woven fabrics folding core body is the folding non-woven fabrics of wave, and non-woven fabrics frame form limit layer covers in non-woven fabrics folding core body's outside periphery, and non-woven fabrics frame form limit layer and non-woven fabrics folding core body height, non-woven fabrics folding core body and non-woven fabrics frame form limit layer bonding. Through improvement, the filter element structure of the air filter maintains good weather resistance, increases effective filtering area, improves filtering performance and has good sealing performance. Obviously, the air filter element is a foldable single-layer filter material for filtration, and only maintenance measures of soot blowing and replacement can be taken in after-sale maintenance, but the soot blowing has poor improvement effect on the filter performance recovery capability of the air filter element, and the problem of high cost in replacing the whole air filter element exists.
