Abstract

The invention relates to a portable, cordless, hair dryer/blower that has an elongated hollow body portion with a mass center line and including therein a blower motor and a heating element and having a posterior end and an anterior end. A handle portion has a longitudinal axis extending substantially transversally from and along the mass center line of the elongated body portion. The handle portion includes switch controls for operating the heating element and the blower motor. A power source has a flat base and a mass center line that, when the power source is attached to the handle portion lies substantially along the longitudinal axis of the handle and the mass center line of the elongated body portion to provide power to the manual controls and to provide a flat base structure for enabling the hair dryer/blower to stand alone.
