Therefore, based on the structure of the cross-flow fan blade, the surface of the cross-flow fan blade is wrapped with the nano titanium dioxide photocatalytic material, and in the working process of the cross-flow fan blade, visible light or ultraviolet light excites the catalytic activity of the nano titanium dioxide photocatalytic material, excites oxygen in air, generates superoxide ions, oxidizes germs and volatile organic compounds in the air, generates water of carbon dioxide, and releases pollution-free air.
Under the condition of natural light, the ultraviolet ray in the light is only about 3%, and the function of the photocatalyst cannot be fully exerted. Therefore, the light generator is arranged in the cross-flow fan blade and used for providing ultraviolet light or visible light with enough intensity to excite the photocatalytic activity of the nano titanium dioxide photocatalytic material, so that a better air purification effect is achieved.
