Ion generator and hairbrush using the same
First Claim
Patent Images
1. A hairbrush which comprises;
- an ion generator for emitting ions; and
a brush head having a brush base formed with a multiplicity of bristles, said brush base having an opening defined therein for passage of the ions from the ion generator to an outside of the hairbrush;
wherein some of the bristles around the opening in the brush base are removed to provide a plain surface area where no bristle exist, wherein the ion generator includes a discharge electrode and wherein a surface area encompassed by a cone having its apex occupied by the discharge electrode and flaring outwardly away from the discharge electrode and passing in touch with a peripheral lip region defining the opening in the brush base has no bristle.

Abstract
An ion generator includes a needle electrode and a ground electrode cooperable with the needle electrode to generate a corona discharge in the air to produce ions. The ground electrode is disposed so as to surround an imaginary extension of a longitudinal axis of the needle electrode and has a portion thereof depleted to provide a split region defined therein. A hairbrush utilizing the ion generator is also disclosed.
