Problems solved by technology

[0003] However, in order to achieve sufficient filtering effect, ordinary filter elements are generally thicker and the air flow rate is relatively small.
One filter element carries the filtering function of various impurity particles, which makes the service life of the air inlet surface of the filter element significantly shorter than that of the air outlet surface and reduces the life of the air filter element. Usually, the air outlet surface can continue to be used, but the air inlet surface has reached the replacement standard, so only Can be replaced as a whole, increasing the cost of use

Abstract

The invention relates to an air filter element with multiple filtering effects. The air filter element comprises electrostatic dust collection paper, a plurality of first micropores, a fiber adsorption layer, a plurality of second micropore, fibers and an activated carbon layer. The first micropores are formed in the electrostatic dust collection paper, the fiber adsorption layer is adhered to theupper side of the electrostatic dust collection paper, the second micropores are formed in the fiber adsorption layer, the first micropores in the electrostatic dust collection paper and the second micropores in the fiber adsorption layer are staggered in position, the second micropores are filled with the fibers, and the activated carbon adsorption layer which is prepared by coating a non-wovenfabric externally with activated carbon particles is adhered to the upper side of the fiber adsorption layer. The air filter element has the advantages that the air filter element is simple in integral structure, has the multiple adsorption effects, can guarantee little difference of using states of positions of the air filter element from the bottom air inlet face to the top air outlet face, andavoids the condition that the whole air filter element is fully replaced as the air outlet face is relatively new while the air inlet face needs to be replaced, so that the air filter element plays afull adsorption role, the service life of the air filter element is prolonged, and the using cost is lowered.

Description

technical field [0001] The invention relates to a filter core, in particular to a filter core with multiple filtering effects. Background technique [0002] The car air filter can bring a cleaner interior environment to the car. Its main requirements are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. The car air filter is mainly responsible for removing particulate impurities in the air. When the piston machine (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. Automobile engines are very precise parts, and even the smallest impurities can damage the engine. Therefore, before the air enters the cylinder, it must be finely filtered by the air filter before entering the cylinder. The air filter element is the patron saint of the engine, and the condition of the air...
