the control system determines whether the number of stopping days N of the air handling system 100 reaches a preset number of days N0, and if the number of stopping days N of the air handling system 100 reaches a preset number of days N0, the ionizer 1 operates in the strong self-cleaning mode at least once.

The ion generator 1 can operate a strong self-cleaning mode for many times to realize the multiple cleaning of dust on the carbon brush electrode 12, thereby achieving a better cleaning effect.

Specifically, the control system controls the fan to change the rotating speed so as to increase or decrease the air outlet speed, when the rotating speed of the fan is high, the air outlet speed is high, and when the rotating speed of the fan is low, the air outlet speed is low. When the ionizer 1 operates in the strong self-cleaning mode, the variation range of the rotating speed of the fan is larger, so that the variation range of the wind speed is larger, the vibration range of the carbon brush fibers can be larger, and a large amount of dust attached to the carbon brush fibers can be separated from the carbon brush fibers more quickly and thoroughly.

Specifically, after the strong self-cleaning mode is turned off, the dust collecting electrodes 13 are not powered and the dust which cannot be attached to the dust collecting electrodes 13 is adsorbed, and the dust can be blown by the wind in the wind outlet channel, so that the dust can be blown away by the wind.
