ABSTRACT:
A diffusion device is provided within or as an attachment to the nozzle of a hair dryer which provides a nearly constant air volume at varying velocities. A hair dryer improvement for varying the air flow output from the hair dryer nozzle. The improvement is a diffusion device which consists of a pair of vanes pivotally mounted downstream of the nozzle. Placement of the vanes in varying positions causes the output air flow to be either concentrated along the nozzle axis or diffused by causing varying portions of the air flow to be directed through the peripheral side wall of the diffusion device. Since the diffusion device offers very little obstruction to the air flow, the volume of air remains nearly constant for the varying diffuser vane positions.
