Sterilizing and virus destroying air filter for automobile

Abstract

The invention relates to the technical field of air filters for automobiles, in particular to a sterilizing and virus destroying air filter for an automobile. The sterilizing and virus destroying air filter comprises a filter element and a frame. A filter material comprises a first sterilizing and virus destroying layer capable of killing bacteria and viruses, a second activated carbon adsorption layer capable of eliminating peculiar smell and adsorbing harmful gas, a third electrostatic fiber layer capable of adsorbing PM2.5, and a fourth electrostatic fiber protection supporting layer. When the sterilizing and virus destroying air filter is used, the sterilizing and virus destroying layer can kill bacteria and viruses in the air, the activated carbon adsorption layer can eliminate peculiar smell and adsorb volatile organic compound (VOC) gas and other harmful gas, the electrostatic fiber layer can catch fine particles through static electricity and adsorb PM2.5, and the filtering efficiency for PM2.5 can reach 99% or above. Meanwhile, the sterilizing and virus destroying air filter is convenient to install and stable.

Description

Technical field: [0001] The invention relates to the technical field of vehicle air filters, in particular to a vehicle air filter capable of sterilizing bacteria and viruses. Background technique: [0002] Car air filter (also known as car air conditioner filter or car air conditioner filter) is mainly used to filter the air in the car compartment and the air circulation inside and outside the car compartment, remove the air in the compartment or enter the air in the compartment Dust, impurities, smoke odor, pollen, etc., to ensure the health of the driver and passengers and remove the peculiar smell in the compartment. [0003] A general vehicle air filter mainly includes a filter element and a frame, and the filter element is installed in the frame. Among them, the filter element includes a filter material folded into a wave shape to increase the specific surface area of ​​the filter, and is the main body of the filter. The PM2.5 (particulate matter with an aerodynamic ...

AI Technical Summary

Problems solved by technology

The prior art PM2.5 (particulate matter with an aerodynamic equivalent diameter of less than or equal to 2.5 microns in the ambient air) vehicle air filter mainly includes a support layer of the first layer, an activated carbon layer of the second layer, and a third layer of activated carbon. The electrostatic fiber layer of the first layer and the protective layer of the fourth layer, although the filtration efficiency of PM2.5 is high, they cannot sterilize and kill viruses, and the installation is inconvenient
