Abstract

Disclosed is an attachment for a hair care appliance including an air inlet end for receiving an airflow from the appliance, an air outlet end for emitting the airflow from the attachment, a wall defining and extending about an airflow path between the air inlet end and the air outlet end, a plate located in the airflow path and configured to guide the airflow towards the airflow outlet end. The plate is configured to divide the airflow path into two sections and the plate includes a plurality of through holes extending between the two sections of the airflow path.

Claims

exact text as granted — not AI-modified
1 . An attachment for a hair care appliance comprising
 an air inlet end for receiving an airflow from the appliance,   an air outlet end for emitting the airflow from the attachment,   a wall defining and extending about an airflow path between the air inlet end and the air outlet end,   a plate located in the airflow path and configured to guide the airflow towards the air outlet end, wherein   the plate is configured to divide the airflow path into two sections and   the plate comprises a plurality of through holes extending between the two sections of the airflow path.   
     
     
         2 . The attachment according to  claim 1 , wherein the plate is configured to divide the airflow path into two equal sections. 
     
     
         3 . The attachment according to  claim 1 , wherein the plurality of through holes are circular through holes. 
     
     
         4 . The attachment according to  claim 1 , wherein the through holes are arranged in a plurality of rows and said plurality of rows extend orthogonal to the longitudinal axis of the attachment. 
     
     
         5 . The attachment according to  claim 4 , wherein the rows of through holes are staggered. 
     
     
         6 . The attachment according to  claim 1 , wherein the plate comprises a non-linear edge proximate to the air outlet end. 
     
     
         7 . The attachment according to  claim 6 , wherein the non-linear edge comprises a wave-shaped profile. 
     
     
         8 . The attachment according to  claim 7 , wherein the wave shaped profile is curved. 
     
     
         9 . The attachment according to  claim 6 , wherein the plate is substantially planar, and the non-linear edge of the plate extends substantially orthogonal to the central longitudinal axis of the attachment. 
     
     
         10 . The attachment according to  claim 6 , wherein non-linear edge when viewed in a plane orthogonal to the plate, has a curved profile. 
     
     
         11 . The attachment according to  claim 1 , wherein the wall is disposed about the longitudinal axis of the attachment. 
     
     
         12 . The attachment according to  claim 1 , wherein the wall comprises an annular wall extending around the longitudinal axis of the attachment, preferably located such that the centre of the annular wall lies on the longitudinal axis of the attachment. 
     
     
         13 . The attachment according to  claim 1 , wherein at least a portion of the wall is tapered. 
     
     
         14 . The attachment according to  claim 1 , wherein the wall tapers inwardly towards the air outlet end. 
     
     
         15 . The attachment according to  claim 12 , wherein the angle of taper of the wall varies between the inlet end and the outlet end. 
     
     
         16 . The attachment according to  claim 1 , wherein, the attachment comprises an external wall surrounding said wall of the attachment. 
     
     
         17 . The attachment according to  claim 1 , wherein the wall and the external wall each comprises a plurality of retention members configured to retain the wall within the external wall. 
     
     
         18 . The attachment according to  claim 1 , wherein the attachment comprises a seat configured to accommodate an RFID tag. 
     
     
         19 . The attachment according to  claim 1 , wherein the inlet end is adapted to receive part of the appliance. 
     
     
         20 . The attachment according to  claim 1 , further comprising a magnet attached to the wall for securing the attachment to the appliance.
