Abstract
A hair brush includes a self-contained ion generator that subjects the hair and scalp being brushed to an outflow of ionized air containing safe amounts of ozone. The ion generator includes a high voltage pulse generator whose output pulses are coupled between first and second electrode arrays. Preferably the first array comprises at least one metal pin spaced coaxially-apart from a metal ring-like structure. Alternatively, the first array may comprise one or more wire electrodes spaced staggeringly apart from a second array comprising hollow "U"-shaped electrodes. Preferably a ratio between effective area of an electrode in the second array compared to effective area of an electrode in the first array exceeds about 15:1 and preferably is about 20:1. An electric field produced by the high voltage pulses between the arrays produces an electrostatic flow of ionized air containing safe amounts of ozone. The outflow of ionized air and ozone is directed between the brush bristles onto the hair and scalp being groomed.
