Problems solved by technology

Existing air cleaning technology mostly uses physical filtration, such as Hepa (High efficiency particulate air) high-efficiency particulate air filter, which blocks dust on the filter screen. The disadvantage is that after a certain period of operation, a large amount of dust and microorganisms are attached to the filter screen. , seriously affecting the quality of indoor air
However, the current air purification system made of titanium dioxide photocatalytic technology has the following problems: 1. The surface of titanium dioxide contains hydroxyl groups, which are hydrophilic, which greatly reduces the photocatalytic reaction rate; 2. The band gap of titanium dioxide is about 3.2eV (387.5 nm), its light absorption is limited in the near ultraviolet region, so the utilization rate of sunlight is very low (about 1%); 3, for the air purification system of multi-layer filter screen constructed of different materials, the removal steps of the filter screen are cumbersome , because the complex structure is not conducive to cleaning, long-term use will lead to a large number of bacteria breeding; 4, the air purification system with enhanced filter adsorption function, the method of tilting the filter or energizing the filter can achieve enhanced adsorption, but the former effect Not ideal, the latter creates safety hazards and wastes energy
