Formaldehyde concentration in the current environment can be obtained through the formaldehyde sensor who sets up in the air purifier wind channel. The air purifier compares the formaldehyde concentration detected by the formaldehyde sensor with a preset concentration value, and when the formaldehyde concentration exceeds the preset concentration value, the discharge adsorption structure is opened, otherwise, the closing state of the discharge adsorption structure is maintained, and formaldehyde adsorption is carried out only by adopting the adsorption material coated on the discharge adsorption structure.
As an alternative embodiment, as shown in fig. 5, after the current value of the environmental parameter exceeds the preset environmental parameter value and the discharge adsorption structure is turned on, the following steps may be performed:
