Abstract

An attachment for a cleaning appliance includes a head and a neck, the neck being adapted to be connected to the mouth of a wand or hose of the cleaning appliance. The neck has a first portion which, in use, lies alongside the mouth of the wand or hose and a second portion which, in use, is spaced away from the mouth of the wand or hose. This arrangement provides a bleed air passageway which allows atmospheric air to be bled into the hose or wand so as to reduce the suction at the main suction opening of the attachment. It also provides an advantageous storage solution for the attachments of the cleaning appliance.

Claims

exact text as granted — not AI-modified
1 . An attachment for a cleaning appliance comprising a head and a neck, the neck being configured for connection to the mouth of a wand or hose of the cleaning appliance, 
 the neck having a first portion which, in use, lies alongside the mouth of the wand or hose and forms a first air passageway, and a second portion which, in use, is spaced away from the mouth of the wand or hose so that a second air passageway separate from the first air passageway is formed between the second portion of the neck and the mouth of the wand or hose.    
   
   
       2 . The attachment of  claim 1 , wherein, in use, the attachment further comprises a suction opening and the first air passageway extends from the suction opening to the mouth of the wand or hose.  
   
   
       3 . The attachment of  claim 2 , wherein, in use, the second air passageway is open to the atmosphere at a location spaced from the suction opening.  
   
   
       4 . The attachment of  claim 1  or  2 , wherein the first portion of the neck is part-cylindrical in shape.  
   
   
       5 . The attachment of  claim 1  or  2 , wherein the second portion of the neck is part-cylindrical in shape.  
   
   
       6 . The attachment of  claim 1  or  2 , wherein the second portion of the neck projects outwardly from the first portion of the neck.  
   
   
       7 . The attachment of  claim 1  or  2 , wherein the second portion of the neck projects inwardly from the first portion of the neck.  
   
   
       8 . The attachment of  claim 7 , wherein the second portion of the neck is planar.  
   
   
       9 . The attachment of  claim 1  or  2 , wherein the head has a portion which forms a continuous surface with the second portion of the neck.

       12 . A cleaning appliance combination comprising an attachment holder for a cleaning appliance, a wand or hose, and at least one attachment comprising a head and a neck, the neck being configured for connection to the mouth of a wand or hose of the cleaning appliance, 
 the neck having a first portion which, in use, lies alongside the mouth of the wand or hose and forms a first air passageway and a second portion which, in use, is spaced away from the mouth of the wand or hose so that a second air passageway separate from the first air passageway is formed between the second portion of the neck and the mouth of the wand or hose.    
   
   
       13 . The combination of  claim 12 , wherein the attachment holder is adapted to be attached to the wand or hose of the cleaning appliance.  
   
   
       14 . The combination of  claim 12  or  13 , wherein the attachment holder has a central wall and a plurality of tongues adapted and arranged to hold the second portions of the attachments against the central wall.
