Attachment for a hand held appliance

Abstract

An attachment for a hair care appliance includes a body having a fluid inlet, a fluid outlet, a fluid flow path extending between the fluid inlet and the fluid outlet, a first vane and a second vane for directing fluid within the fluid flow path towards the fluid outlet wherein the body comprises at least two extended plates and the fluid outlet comprises a slot defined by an overlap between the at least two extended plates wherein the first vane and the second vane are curved and positioned within the overlap between the at least two extended plates wherein the first vane and the second vanes curve in opposite directions. The fluid inlet may have a first cross sectional area, the body includes an outer wall that has a second cross sectional area, and wherein the second cross sectional area is greater than the first cross sectional area.

         5 . The attachment of  claim 4 , wherein the body has a first end and a second end and the fluid inlet is at the first end. 
     
     
         6 . The attachment of  claim 1 , wherein the first vane is adjacent the fluid inlet. 
     
     
         7 . The attachment of  claim 1 , wherein the first vane has a convex surface and the convex surface faces the fluid inlet. 
     
     
         8 . The attachment of  claim 7 , wherein the second vane has a concave surface and the concave surface faces the fluid inlet. 
     
     
         9 . The attachment of  claim 1 , wherein the first vane and the second vane are aerofoil in shape. 
     
     
         10 . The attachment of  claim 1 , wherein the fluid outlet extends along an axis between the first end and the second end. 
     
     
         11 . The attachment of  claim 10 , wherein the second vane comprises a plurality of vanes spaced along the extended plates. 
     
     
         12 . The attachment of  claim 11 , wherein the plurality of vanes are irregularly spaced along the extended plates. 
     
     
         13 . The attachment of  claim 11 , wherein the plurality of vanes are angled to the axis of the body. 
     
     
         14 . The attachment of  claim 13 , wherein angles of at least some of the vanes of the plurality of vanes differ from angles of respective adjacent vanes. 
     
     
         15 . The attachment of  claim 14 , wherein angles of the vanes of the plurality of vanes with respect to the axis increases towards the second end. 
     
     
         16 . The attachment of  claim 11 , wherein the size of the plurality of vanes varies along the extended plate. 
     
     
         17 . The attachment of  claim 16 , wherein each of the plurality of vanes has the same profile. 
     
     
         18 . The attachment of  claim 11 , wherein the at least one vane is substantially the same length as the overlap between the at least two extended plates. 
     
     
         19 . The attachment of  claim 1 , wherein the slot is curved with respect to an axis of the body. 
     
     
         20 . The attachment of  claim 19 , wherein each extended plate is formed from a strut and a plate.
