Accessory for hair treatment device

Abstract

An air deflector ( 12, 12 a ) for an electric hair dryer ( 10 ) includes a housing ( 24, 24 a ) with an air passageway therethrough, and a nozzle ( 28, 28 a ) in the air passageway. The nozzle ( 28, 28 a ) includes an air inlet ( 30 ) receiving all the air entering the housing ( 24, 24 a ) and an air outlet ( 32 ) allowing the air received by the air inlet ( 30 ) to exit. The nozzle ( 28, 28 a ) oscillates relative to the housing ( 24, 24 a ) to continuously change the direction of the air from the air outlet ( 32 ).

1 . An accessory for a hair treatment device, said accessory comprising:
 a housing with an air passageway therethrough; and   a nozzle in said air passageway;   wherein said nozzle includes an air inlet and an air outlet, said air inlet receiving at least part of air entering said housing, and said air outlet allowing exit of said air received by said air inlet; and   wherein said nozzle is oscillatable relative to said housing to continuously change the direction of the air exiting said nozzle.   
     
     
         2 . The accessory according to  claim 1  wherein said nozzle is oscillatable relative to said housing about an axis fixed relative to said housing. 
     
     
         3 . The accessory according to  claim 1  wherein the centre of gravity of said nozzle is away from a longitudinal plane containing said axis. 
     
     
         4 . The accessory according to  claim 1  wherein said nozzle is oscillatable upon passing of air from said air inlet to said air outlet. 
     
     
         5 . The accessory according to  claim 1  wherein said nozzle is freely hinged to said housing. 
     
     
         6 . The accessory according to  claim 1  wherein the area of said air outlet of said nozzle is smaller than the area of said air inlet of said nozzle. 
     
     
         7 . The accessory according to  claim 1  further comprising a locking member movable between a locking position in which oscillating movement of said nozzle relative to said housing is prevented and an unlocked position in which oscillating movement of said nozzle relative to said housing is allowed. 
     
     
         8 . The accessory according to  claim 1  further comprising at least one inwardly extending rim at or adjacent to said air outlet of said nozzle. 
     
     
         9 . The accessory according to  claim 8  further comprising a plurality of inwardly extending rims at or adjacent to said air outlet of said nozzle. 
     
     
         10 . The accessory according to  claim 1  wherein said air inlet is adapted to receive substantially all air entering said housing. 
     
     
         11 . A hair treatment device set comprising a hair treatment device and an accessory for a hair treatment device which are releasably engageable with each other, said accessory including:
 a housing with an air passageway therethrough; and   a nozzle in said air passageway;   wherein said nozzle includes an air inlet and an air outlet, said air inlet receiving at least part of air entering said housing, and said air outlet allowing exit of said air received by said air inlet; and   wherein said nozzle is oscillatable relative to said housing to continuously change the direction of the air exiting said nozzle.   
     
     
         12 . The hair treatment device set according to  claim 11  wherein said accessory is releasably engageable with said hair treatment device in at least two configurations, and wherein an axis of oscillation of said nozzle differs by substantially 90° between said two configurations. 
     
     
         13 . The hair treatment device set according to  claim 11  wherein said accessory, when engaged with said hair treatment device, is rotatable relative to said hair treatment device about an axis substantially parallel to a central longitudinal axis M-M of said accessory. 
     
     
         14 . The hair treatment device set according to  claim 11  wherein said air inlet is adapted to receive substantially all air entering said housing. 
     
     
         15 . A hair treatment device comprising:
 an air entrance and an air exit defining an air passage therebetween;   an air flow generator adapted to draw air into said device through said air entrance and to drive air out of said device through said air exit; and   a nozzle in said air passage;   wherein said nozzle includes an air inlet and an air outlet, said air inlet receiving at least part of air flowing from said air flow generator, and said air outlet allowing exit of said air received by said air inlet; and   wherein said nozzle is oscillatable relative to said passage to continuously change the direction of the air exiting said nozzle.   
     
     
         16 . The hair treatment device according to  claim 15  wherein said nozzle is positionable relative to said air passage in at least two configurations, and wherein an axis of swiveling of said air flow deflector differs by substantially 90° between said two configurations. 
     
     
         17 . The hair treatment device according to  claim 15  wherein said nozzle is rotatable relative to said passage about an axis substantially parallel to a central longitudinal axis A-A of said nozzle. 
     
     
         18 . The hair treatment device according to  claim 14  wherein said air inlet receives substantially all air flowing from said air flow generator.
