The photocatalyst material is usually attached to a hard honeycomb ceramic substrate or other hard substrates, but the structural shape cannot be changed at will, so that the miniaturization design of products is limited. In addition, the excitation light source is usually a fluorescent ultraviolet lamp, and the energy efficiency ratio is low because the light source has useless heat energy loss. And the purple light lamp tube is embedded in the air duct of the purifier, so that the miniaturization design of the product is limited by the structural form, and the wind resistance is increased.
