Problems solved by technology
[0004] Existing nano-titanium dioxide disinfection devices generally include a housing in which an air inlet, an air outlet, and a fan are arranged, and a base material coated with a titanium dioxide sterilizing material is arranged between the air inlet and the air outlet. However, the air volume of the fan is large and the wind speed is relatively fast. , the base material is in a static state, so in many cases the toxic and harmful gases in the air have not been cleaned up, and they have already gone out from the air outlet. Small, not conducive to effective air purification and disinfection, so the bactericidal effect needs to be strengthened

Description
technical field [0001] The invention relates to the technical field of air purification and disinfection, more specifically, it relates to a titanium dioxide air purification and disinfection device. Background technique [0002] At present, the air has been regarded as one of the main media of disease transmission. Indoor air pollution refers to the substances contained in the air in the closed space where people live that are harmful to human health and whose concentration exceeds the national standard, thus causing harm to human health. The air is full of various physical, chemical and microbial pollutants that endanger human health. Due to the relatively closed indoor environment, moisture will also breed various microorganisms, resulting in biological pollution. At present, there are more than 400 kinds of pollutants that have been confirmed, which have far exceeded people's estimates. [0003] The quality of indoor air directly affects the life and health of the hum...
