Cleaner nozzle

Abstract

The present disclosure relates to a cleaner nozzle including: a nozzle housing in which a suction inlet that sucks dust-containing air is formed; a damper which is provided behind the suction inlet of the nozzle housing and elastically supports a cleaning object; and a cover which is provided behind the damper of the nozzle housing and covers at least a portion of the damper. As a result, the damper is prevented from being excessively deformed or damaged.

What is claimed is: 
     
         1 . A cleaner nozzle comprising:
 a nozzle housing in which a suction inlet that sucks dust-containing air is formed;   a damper which is provided behind the suction inlet of the nozzle housing and elastically supports a cleaning object; and   a cover which is provided behind the damper of the nozzle housing and covers at least a portion of the damper.   
     
     
         2 . The cleaner nozzle of  claim 1 , wherein the damper is supported by the cleaning object and elastically deformed when the nozzle housing is placed on the cleaning object. 
     
     
         3 . The cleaner nozzle of  claim 2 , wherein the cover is disposed to be spaced apart from the damper in the front-rear direction. 
     
     
         4 . The cleaner nozzle of  claim 3 , wherein, when the damper is elastically deformed, the damper protrudes rearward and becomes in contact with the cover. 
     
     
         5 . The cleaner nozzle of  claim 2 , wherein the damper is elastically deformed while being compressed in a direction perpendicular to the cleaning object and extended rearward. 
     
     
         6 . The cleaner nozzle of  claim 1 ,
 wherein the damper is provided on the nozzle housing and has an inner empty space, and
 wherein the damper comprises:
 a floor support portion which supports the cleaning object; 
 a rear inclined portion which is disposed to be inclined to be spaced from the cleaning object toward the rear from the floor support portion; and 
 a front inclined portion which is disposed to be inclined to be spaced from the cleaning object toward the front from the floor support portion. 
 
   
     
     
         7 . The cleaner nozzle of  claim 6 , further comprising an imaginary line extending from the rear inclined portion,
 wherein the cover is disposed to intersect the imaginary line.   
     
     
         8 . The cleaner nozzle of  claim 6 , wherein the damper has a non-uniform thickness. 
     
     
         9 . The cleaner nozzle of  claim 6 , wherein a thickness of the floor support portion is greater than thicknesses of the rear inclined portion and the front inclined portion. 
     
     
         10 . The cleaner nozzle of  claim 9 , wherein the floor support portion comprises a convex portion protruding toward the cleaning object. 
     
     
         11 . The cleaner nozzle of  claim 6 , wherein an inclination angle of the front inclined portion with respect to the cleaning object is smaller than an inclination angle of the rear inclined portion with respect to the cleaning object. 
     
     
         12 . The cleaner nozzle of  claim 1 , wherein the cover comprises:
 a cover body which is connected to the nozzle housing; and   a flap which is formed to protrude from the cover body toward the cleaning object, is formed to be spaced from the cleaning object by a predetermined distance,   wherein the damper becomes in contact with the flap according to the elastic deformation of the damper.   
     
     
         13 . A cleaner nozzle comprising:
 a nozzle housing in which a suction inlet that sucks dust-containing air is formed; and   a damper which is provided behind the suction inlet of the nozzle housing and elastically supports a cleaning object,   wherein the damper is provided on the nozzle housing, has an inner empty space, and has a non-uniform thickness.
