技术领域technical field

Among the above-mentioned types of air purifiers, the filter adsorption type has the disadvantage that the filter screen has a single structure and can only filter a small number of air impurities, and because the filter screen is too simple, the filtering effect on air impurities is not good, while other types of air purifiers , the functions are relatively single, have strong pertinence to air impurities, and will be affected by the environment, such as photocatalyst type, generally only for indoor formaldehyde, moss and other harmful gases, and will affect the indoor color wall, furniture surface paint In addition, when the photocatalyst material purifies the indoor air, it needs a certain amount of time and light. These all have restricted the development of air purifier.
