Dust agitator and vacuum cleaner having the same

Abstract

A dust agitator of a vacuum cleaner is disclosed. The dust agitator of the vacuum cleaner includes a thick and a thin bristle member embedded in a single bristle member suction opening so that abrasion of a surface being vacuumed can be reduced and cleaning efficiency can be increased. The dust agitator includes a dust agitator body, a receiving hole for a bristle member being configured along the dust agitator body, and a bristle member comprising a plurality of first and second bristle members of varying thickness being embedded in the receiving hole.

1 . A dust agitator of a vacuum cleaner comprising; 
 a dust agitator body;    a receiving hole for a bristle member, configured along the dust agitator body; and    a bristle member embedded in the bristle receiving hole, and including a plurality of bristle members of varying thickness.    
   
   
       2 . The dust agitator according to  claim 1 , wherein the bristle member comprises; 
 a first bristle member embedded in the bristle receiving hole; and    a second bristle member embedded in the receiving hole together with the first bristle member, and formed thinner than the first bristle member.    
   
   
       3 . The dust agitator according to  claim 2 , wherein the first bristle member has a diameter of approximately 0.225˜0.275 mm.  
   
   
       4 . The dust agitator according to  claim 2 , wherein the second bristle member has a diameter of approximately 0.18˜0.220 mm.  
   
   
       5 . The dust agitator according to  claim 2 , wherein the first bristle member has a diameter of approximately 0.25 mm, and the second bristle member includes a diameter of approximately 0.20 mm.  
   
   
       6 . The dust agitator according to one of  claim 1 , wherein the first bristle member and the second bristle member are embedded in the bristle receiving hole at an equal ratio.  
   
   
       7 . The dust agitator according to one of  claim 2 , wherein the first bristle member and the second bristle member are embedded in the bristle receiving hole at an equal ratio.  
   
   
       8 . The dust agitator according to one of  claim 3 , wherein the first bristle member and the second bristle member are embedded in the bristle receiving hole at a equal ratio.  
   
   
       9 . The dust agitator according to one of  claim 4 , wherein the first bristle member and the second bristle member are embedded in the bristle receiving hole at a equal ratio.  
   
   
       10 . The dust agitator according to one of  claim 5 , wherein the first bristle member and the second bristle member are embedded in the bristle receiving hole at a equal ratio.  
   
   
       11 . The dust agitator according to  claim 1 , wherein the bristle receiving hole is helically configured along an outer surface of the dust agitator body.  
   
   
       12 . A vacuum cleaner comprising 
 a cleaner body;    a suction nozzle connected to the cleaner body to draw in alien substances of a surface being vacuumed;    a dust agitator body received rotatably in the suction nozzle;    a receiving hole for the bristle member, configured along the dust agitator body at a regular interval; and    a bristle member embedded in the bristle receiving hole and including a plurality of bristles of varying thickness.
