An air disinfection device includes a shell having entry and exhaust ports, a power supply installed above the shell, and a dust collecting cylinder installed on the shell, connected to a negative electrode of the power supply, and having air inlet and outlet. The air inlet and the air outlet are communicated with the entry port and the exhaust port, respectively. The conductive rod has one end installed above the shell and connected to a positive electrode of the power supply, and the other end located in the dust collecting cylinder and close to the air inlet. An arrangement direction of the conductive rod is consistent with an axis direction of the dust collecting cylinder. The power supply provides high-voltage current to the conductive rod to form a symmetrically distributed high-voltage electrostatic field inside the dust collecting cylinder to sterilize and disinfect air passing through the dust collecting cylinder.

A first imaging unit obtains an image of at least one of a jet flow, droplets or satellite drops. Based on a feature value of the at least one of the jet flow, the droplets or the satellite drops in the image, a controller controls a timing of starting to supply charges from a charge supply unit to a final jet flow droplet in one period of vibrations of a vibration element or an amplitude of a drive voltage applied to the vibration element so as to cause variation of a side stream to fall within a reference range.
