Suction Head For Use In A Vacuum Cleaning Appliance, And A Vacuum Cleaning Appliance Comprising Thereof

Abstract

A suction head for use in a vacuum cleaning appliance. The suction head comprises a body adapted to engage a surface to be cleaned, the body comprises an inlet for receiving dust from the surface under suction, and an outlet attachable with a suction tube of the vacuum cleaning appliance; an air passageway adapted to direct air flow from the inlet to the outlet, the air passageway comprises an air channel connecting with the inlet at one end, and a hollow connecting means connecting with the outlet at another end; wherein the connecting means is rotatable to pivot about an axis along a direction of the air flow, such that opening of the air passageway remains substantially constant regardless of the pivotal movement of the connecting means.

What is claimed is: 
     
         1 . A suction head for use in a vacuum cleaning appliance, comprising:
 a body adapted to engage a surface to be cleaned, the body comprises an inlet for receiving dust from the surface under suction, and an outlet attachable with a suction tube of the vacuum cleaning appliance;   an air passageway adapted to direct air flow from the inlet to the outlet, the air passageway comprises an air channel connecting with the inlet at one end, and a hollow connecting means connecting with the outlet at another end;   wherein the connecting means is rotatable to pivot about an axis along a direction of the air flow, such that opening of the air passageway remains substantially constant regardless of the pivotal movement of the connecting means.   
     
     
         2 . The suction head according to  claim 1 , wherein the air channel comprises a non-linear air channel arranged on a plane substantially parallel to the surface. 
     
     
         3 . The suction head according to  claim 2 , wherein the non-linear air channel comprises a U-shaped air channel connecting the inlet with the connecting means. 
     
     
         4 . The suction head according to  claim 1 , wherein the connecting means defines an L-shaped air passage connecting the air channel with the outlet. 
     
     
         5 . The suction head according to  claim 4 , wherein the connecting means is arranged in a T-shaped configuration defining the L-shaped air passage at two adjacent arms substantially perpendicularly arranged. 
     
     
         6 . The suction head according to  claim 1 , wherein the connecting means is rotatable to pivot the outlet between a lower position and a raised position, with a pivot angle between about zero degrees to about 90 degrees, respectively, in respect of the surface. 
     
     
         7 . The suction head according to  claim 1 , wherein the connecting means comprises a substantially cylindrical body rotatable about a central, longitudinal axis. 
     
     
         8 . The suction head according to  claim 1 , wherein the air channel and the connecting means are connected via one or more sealing means. 
     
     
         9 . The suction head according to  claim 1 , wherein the inlet comprises a forward-facing opening arranged at a front portion of the body. 
     
     
         10 . The suction head according to  claim 9 , wherein the forward-facing opening  24  is configured to extend further downwardly and inwardly to allow for a forward suction and a downward suction from the surface to be cleaned. 
     
     
         11 . The suction head according to  claim 9 , wherein the body further comprises a front suction chamber at the front portion of the body, the front suction chamber being arranged to be in fluid communication with the forward-facing opening. 
     
     
         12 . The suction head according to  claim 11 , wherein the front suction chamber defines a forward-facing nozzle at a front edge the body. 
     
     
         13 . The suction head according to  claim 12 , wherein the forward-facing nozzle comprises an elongated nozzle extending along at least partially the front edge of the body. 
     
     
         14 . The suction head according to  claim 11 , wherein the front suction chamber comprises a cover. 
     
     
         15 . The suction head according to  claim 14 , wherein the cover is movable to adjust size of the forward-facing opening. 
     
     
         16 . The suction head according to  claim 14 , wherein the cover is substantially transparent. 
     
     
         17 . The suction head according to  claim 1 , wherein the body further comprises a substantially planar base portion for positioning the body on the surface. 
     
     
         18 . The suction head according to  claim 1 , wherein the outlet comprises an attaching means for attaching the body with the suction tube of a vacuum cleaning appliance. 
     
     
         19 . A vacuum cleaning appliance, comprising a suction head according to  claim 1 . 
     
     
         20 . A method of manufacturing a suction head according to  claim 1 , comprising the steps of:
 providing a body for engaging a surface to be cleaned, the body comprises an inlet for receiving dust from the surface under suction, and an outlet attachable with a suction tube of the vacuum cleaning appliance;   providing an air passageway adapted to direct air flow from the inlet to the outlet, the air passageway comprises an air channel connecting with the inlet at one end, and a hollow connecting means connecting with the outlet at another end;   wherein the connecting means is rotatable to pivot about an axis along a direction of the air flow, such that opening of the air passageway remains substantially constant regardless of the pivotal movement of the connecting means.
