Problems solved by technology

[0002] Car air conditioning filter is also called air conditioning filter, its function is to filter the air entering the air conditioning box for the driver and passengers to breathe. The filter material mainly includes small particles, pollen, industrial waste gas and dust in the air; the original car air conditioner The filter element only filters PM2.5 particles, that is, 2.5 micron particles, and the filtering effect on smaller particles is poor. For example, the filtration efficiency of 0.3 micron particles is about 75%, and the high efficiency is only about 90%. Cannot meet the health needs of the occupants, especially under the new coronavirus epidemic

Abstract

The invention relates to an air conditioner filter element which comprises at least two filter layers, namely a filter layer and an antibacterial layer. The filter layer and the antibacterial layer are compounded into one layer through materials, filtered gas firstly enters the filter layer and then enters the antibacterial layer, and at least part of the filter layer is made of melt-blown fibers.The air conditioner filter element further comprises a pre-filter layer, the pre-filter layer is placed on the filter layer, and filtered gas firstly passes through the pre-filter layer. The pre-filter layer is at least partially made of electrostatic fibers. And metal bactericidal ions are arranged in the antibacterial layer. The metal bactericidal ions are at least one of copper ions and silverions. And the filter layer comprises an N95 filter layer or a composite activated carbon layer and an N95 filter layer. The invention further provides an automobile air conditioner filter which comprises the air conditioner filter element. The invention further provides a method for manufacturing the air conditioner filter element.

Description

Technical field[0001]The present invention relates to the technical field of air purification, in particular to an automobile air-conditioning filter, an air-conditioning filter element and a manufacturing method thereof.Background technique[0002]Automobile air-conditioning filter is also called air-conditioning filter. Its function is to filter the air entering the air-conditioning box for the driver and passengers to breathe. The filter material mainly contains small particles in the air, pollen, industrial exhaust gas and dust; the original automobile air-conditioning The filter element only filters for PM2.5 particles, that is, 2.5 micron particles, but has a poor filtering effect for smaller particles. For example, the filtration efficiency for 0.3 micron particles is about 75%, and the efficiency is only about 90%. Can not meet the health needs of the occupants, especially the health needs of the new coronavirus epidemic.Summary of the invention[0003]In view of this, the purpo...
