Abstract
A filtering device for killing pathogenic microorganisms using deep ultraviolet laser is provided, including a main body and a deep ultraviolet laser module, the main body is configured for accommodating gas having pathogenic microorganisms; the deep ultraviolet laser module is connected to the main body and configured for totally reflecting the deep ultraviolet laser for multiple times to form a dense and regular deep ultraviolet laser net, such that the gas is filtered in the dense and regular deep ultraviolet laser net to achieve the killing of the pathogenic microorganisms in the gas. The deep ultraviolet laser module includes a deep ultraviolet laser apparatus and a reflection adjusting assembly, the deep ultraviolet laser apparatus is connected to the main body, and the reflection adjusting assembly is configured for adjusting the density of the deep ultraviolet laser net.
