Diffuser for hair dryer

A diffuser device for attenuating the air flow of a hair dryer, including;

• a tubular body member having a bore therethrough, said bore having an input end for receiving air flow from the hair dryer and an output end for directing the air flow from the hair dryer;
• a diffuser plate, and means for securing said diffuser plate in said bore in rotatable fashion;
• means for pivoting said diffuser plate from an open position in which said bore is substantially unobstructed to a closed position in which said bore is substantially obstructed;
• means for venting the air flow from the dryer when said diffuser plate is disposed in said closed position, including a plurality of vent holes extending through said tubular body member to said bore, said vent holes disposed adjacent to said diffuser plate and between said diffuser plate and said input end;
• means for emitting an attenuated flow of air from said output end when said diffuser plate is disposed in said closed position, including a plurality of small holes extending through said diffuser plate and arrayed in spaced apart fashion;
• said means for securing said diffuser including a pivot shaft extending across said bore and a gear secured to said pivot shaft;
• said means for pivoting said diffuser plate including an arm extending longitudinally and generally parallel to the axis of said bore and a plurality of teeth carried on said arm and disposed to engage said gear in rack and pinion fashion;
• and,
• spring means for resiliently biasing said diffuser plate to said open position.

• a plurality of diffuser plates, and means for securing said diffuser plates in said bore in rotatable fashion;
• means for pivoting said diffuser plates through a continuously variable angle from an open position in which said bore is substantially unobstructed to a closed position in which said bore is completely obstructed;
• means for venting the air flow from the dryer when said diffuser plates are disposed in said closed position, including a plurality of vent holes extending through said tubular body member to said bore, said vent holes disposed in an annular array positioned adjacent to said diffuser plates in said closed position and between said diffuser plates and said input end;
• and,
• means for emitting an attenuated flow of air from said output end when said diffuser plate is disposed in said closed position, including a plurality of small holes extending through said diffuser plates and arrayed in spaced apart fashion.
