Background
The high-voltage power supply control mode of the air purifier on the existing market, for example, an electrostatic air purifier, is one of the control core technologies of the air purifier.
The load characteristics of the dust collecting component of the electrostatic purifier can change along with the increase of dust collection, the change of humidity and other environmental factors. For example, under the same voltage value of 7.5KV, the ozone of a brand-new dust collecting component is very low, and the sterilization and dust removal performance is very good; when the purification assembly is full of dust after one month of dust collection, a serious ignition may be generated by a voltage of 7.5KV, the ozone generation rate is greatly increased, and the dust removal performance is remarkably reduced.
Proper control of the purification components of an air purifier is necessary and critical, since ozone can be overproof if the control is too loose and optimal performance of the air purifier cannot be achieved if the control is too dead.
In view of the above problems, no effective solution has been proposed.
