Air purification device, control method and storage medium

The invention discloses an air purification device, a control method and a storage medium, the air purification device comprises an ion release assembly for releasing plasma, and the control method comprises the following steps: driving the ion release assembly to discharge at a single power, the power of the ion release assembly is adjusted so that the ozone concentration of the air is smaller than the preset concentration; obtaining a current sterilization rate; if the current sterilization rate is not larger than the preset sterilization rate, the average power of the ion release assembly is obtained, the average power serves as the first average power, the ion release assembly is driven to operate in a multi-power circulation mode, and the average power of the ion release assembly is made to be equal to the first average power. The technical scheme provided by the invention aims to solve the technical problems that an existing air purification device is difficult to realize that the ozone concentration does not exceed the standard and the sterilization effect is good at the same time.
