In this embodiment, a photocatalytic layer is coated on the inner wall of the chamber of the photoplasm module, the broad-wave-width photon tube is disposed on one side of the photocatalytic net, or the photocatalytic layer is disposed inside the broad-wave-width photon tube, the photocatalytic layer is made of nano-scale noble metal catalytic materials, and under the catalysis of specific nano-scale noble metal mediums, the broad-wave-width photon tube irradiates air to generate a large amount of hydroxide ions, super-oxygen ions, hydrogen peroxide and pure negative oxygen ions, thereby forming photo-hydrogen ions, and being capable of rapidly and effectively killing more than 99% of bacteria, viruses and mold in the air, and resolving the peculiar smell in the air, thereby achieving the effect of purifying the air.
In this embodiment, the broad-spectrum photon tube may be a broadband ultraviolet light tube, and compared with an ultraviolet light tube having UVC ultraviolet and/or UVD ultraviolet wavelength bands, the broad-spectrum ultraviolet light tube irradiates air under the catalysis of a specific nanoscale noble metal medium, so that a large amount of hydroxide ions, super oxygen ions, hydrogen peroxide and pure negative oxygen ions can be generated, and the sterilization effect is improved.
The foregoing description is only illustrative of the preferred embodiment of the present invention, and is not to be construed as limiting the invention, but is to be construed as limiting the invention to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the invention, may be made by those skilled in the art without departing from the scope of the invention.
