After generating high voltage, the high-voltage electrode sheet pulls the water droplets on the surface of the discharge electrode upward to the tip to form a Taylor cone and generate corona discharge, ionizing to generate active composite particles. When using a needle-shaped electrode, there is less water at the top, and it is easy to produce a large amount of ozone; it is difficult to form a Taylor cone when using a circular electrode; and the peach-shaped electrode is easier to form a Taylor cone of discharge and produces less ozone because it meets the Taylor curve.
