technical field

The utility model relates to the technical field of air purification, in particular to an air conditioner with a photocatalyst air purification device.

Background technique

After the air conditioner is used for a period of time, a large amount of dust and dirt will accumulate on the filter screen, evaporator and air supply system, resulting in a large number of molds, bacteria, viruses and insects.
