Description

TECHNICAL FIELD

BACKGROUND

In recent years, with the development of industrialization, the rising number of automobiles, and the low quality of fuel, the air quality has declined and the environment has been seriously polluted. Even though ventilation brings fresh air, it brings a lot of outdoor haze into rooms, which will harm people's respiratory systems and affect their health. Therefore, a variety of novel multi-functional composite air purification devices are developed to purify dust, haze, formaldehyde, and other harmful substances in the air.

Most existing indoor air purification devices adopt large air purifiers, which not only have large volumes, occupy indoor space, but also are difficult to maintain after being damaged, and have high maintenance costs.
