ABSTRACT:
A hair dryer is provided which reduces static electricity in hair being dried. A point source for electron release, such as a needle, is positioned in a reflector in the air stream of the dryer. The point source is electrically connected to an electron source, such as a piezoelectric crystal, located in the handle of the hair dryer. The piezoelectric crystal is wired to produce an electric charge, the charge being initially a negative electric charge. The crystal is connected to the point source and thus provides electrons to the point source. These enter the air, ionizing air molecules, and the resulting ions are carried to the hair, neutralizing the static charge in the hair. The piezoelectric crystal, a supporting frame, a lever arm, and an arm lever cover are mounted in the dryer handle. The lever arm cover can be pivoted, resulting in the lever arm being moved when the handle is squeezed or released. Release of the lever arm results in it returning to its original position.
