Hair dryer with rotary brush

The invention is a rotary brush-hair dryer combination. Air is heated and propelled from the handle of a grooming implement outwardly through a fixed conduit. The air exits from the conduit through a slot which extends from near the end of the conduit furthest from the handle to adjacent the handle. The slot is restricted in size so that the hot air leaves the conduit and is directed throughout a limited angle. Interchangeable tubular brushes are provided which fit over the conduit. The brushes communicate rotatably with a motor within the handle. A number of holes are provided adjacent where the bristles join the brush so that the hot air which flows from the slot in the conduit can flow out primarily through those of the openings opposite the slot. A switch on the handle allows for change of direction of rotation or for shutting off rotation completely. The implement includes an overload switch which will stop rotation of the brush when hair becomes entangled in it. An accessible reset button is also provided for the overload switch.
