Abstract
A selectively adjustable air deflecting damper is provided in the air exhaust barrel of an electrically heated hand-held hair drier for adjusting the area of the air discharge orifice and concomitantly the air velocity of the heated air discharge. The damper is pivoted in the barrel downstream of the air heating element and is selectively movable between first and second positions providing maximum and minimum effective orifice openings for producing a dispersed and a concentrated air flow, respectively. The damper is spring biased to its first position and operated by a trigger arranged for actuation by a digit of the hand holding the hair drier during use.
