Abstract

The invention belongs to the technical field of air purifiers, and particularly relates to an air purifier and a control method thereof. According to the control method of the air purifier, the concentration of bacteria entering the air purifier is detected through a first biosensor, and when it is detected that the concentration of the bacteria entering the air exceeds a limit value, a controllerstarts a first sterilization device to work to sterilize the air entering the air purifier; when the air enters a filtering device, a second biosensor detects the concentration of bacteria on the filtering device, and when it is detected that the concentration of the bacteria on the filtering device exceeds the limit value, the controller starts a second sterilization device to sterilize the airfiltered by the filtering device. The bacterial concentration of the air and the filtering device is monitored in real time, the concentration of bacteria in the air is monitored through the biosensors, and one or two sterilization devices are automatically started, so that the sterilization effect is more thorough; the air obtained after sterilization treatment is further subjected to ozone treatment, so that the air is fresher.

Description

Technical field [0001] The invention belongs to the technical field of air purifiers, and specifically relates to an air purifier and a control method thereof. Background technique [0002] Most of people's production and life are in an indoor environment, and the quality of indoor air is of vital importance to human health. Studies have shown that there are various particle pollutants of various particle sizes such as coarse particles, inhalable particles, fine particles, ultrafine particles, radon, formaldehyde, benzene, ammonia, and esters, trichloroethylene and other volatile organic compounds in indoor spaces, and Pollen, bacteria, molds and other biological pollutants. The above-mentioned indoor air pollutants are extremely harmful to human health. Therefore, it is very important to effectively eliminate air pollutants. [0003] For example, the patent number CN105814436A discloses a biosensor and an air purifier with the biosensor. The biosensor can detect the concentration...
