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 inlet and outlet and at least one vane for directing fluid within the fluid flow path towards the fluid outlet, wherein the body includes at least two extended plates and the fluid outlet includes a slot defined by an overlap between the at least two extended plates, and wherein the at least one vane is positioned within the overlap between the at least two extended plates. The body may be elongate, may have a first end including the fluid inlet, and may extend along an axis. The fluid outlet may extend along the axis between the first end and a second end. The at least one vane may direct fluid flowing in the fluid flow path from a first direction to a second direction.

1 . An attachment for a hair care appliance comprising a body having a fluid inlet, a fluid outlet, a fluid flow path extending between the fluid inlet and the fluid outlet and at least one 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 and wherein the at least one vane is positioned within the overlap between the at least two extended plates. 
     
     
         2 . The attachment of  claim 1 , wherein the body is elongate and extends along an axis. 
     
     
         3 . The attachment of  claim 1 , wherein the elongate body has a first end and a second end and the fluid inlet is at the first end. 
     
     
         4 . The attachment of  claim 3 , wherein the fluid outlet extends along the axis between the first end and the second end. 
     
     
         5 . The attachment of  claim 1 , wherein the at least one vane is an aerofoil. 
     
     
         6 . The attachment of  claim 1 , wherein the at least one vane directs fluid flowing in the fluid flow path from a first direction to a second direction. 
     
     
         7 . The attachment of  claim 6 , wherein the first direction is parallel to the axis of the body. 
     
     
         8 . The attachment of  claim 7 , wherein the second direction is 85° to 95° from the axis. 
     
     
         9 . The attachment of  claim 1 , wherein the at least one vane comprises a plurality of vanes extending from the first end of the body towards the second end of the body. 
     
     
         10 . The attachment of  claim 9 , wherein the plurality of vanes are irregularly spaced along the body. 
     
     
         11 . The attachment of  claim 10 , wherein the plurality of vanes are progressively closer together towards the second end. 
     
     
         12 . The attachment of  claim 9 , wherein the plurality of vanes are angled to the axis of the body. 
     
     
         13 . The attachment of  claim 12 , wherein the angle of at least some of the plurality of vanes differs from adjacent vanes. 
     
     
         14 . The attachment of  claim 13 , wherein the angle of the plurality of vanes with respect to the axis increases towards the second end. 
     
     
         15 . The attachment of  claim 9 , wherein the size of the plurality of vanes varies between the first end and the second end. 
     
     
         16 . The attachment of  claim 15 , wherein the plurality of vanes are progressively smaller towards the second end of the body. 
     
     
         17 . The attachment of  claim 15 , wherein each of the plurality of vanes has the same profile. 
     
     
         18 . The attachment of  claim 1 , wherein the slot is curved with respect to the axis of the body. 
     
     
         19 . The attachment of  claim 1 , wherein the at least one vane is substantially the same length as the overlap between the at least two extended plates. 
     
     
         20 . The attachment of  claim 1 , wherein one of the at least one vanes has a structural function as well as a flow directing function. 
     
     
         21 . The attachment of  claim 1 , wherein each extended plate is formed from a strut and a plate. 
     
     
         22 . The attachment of  claim 21 , wherein the slot is formed from a strut and a plate from adjacent extended plates.
