Suction brush of vacuum cleaner

Abstract

A suction brush of a vacuum cleaner includes: a body configured to communicate with a dust collection device and including at least one suction port; a cover configured to cover a top of the body; and at least one rolling pin configured to be rotatably coupled at a bottom of the body.

1 . A suction brush of a vacuum cleaner, comprising: 
 a body configured to communicate with a dust collection device and including at least one suction port;    a cover configured to cover a top of the body; and    at least one rolling pin configured to be rotatably coupled at a bottom of the body.    
   
   
       2 . The suction brush of  claim 1 , wherein the at least one rolling pin includes a first rolling pin installed at a first side of the body and a second rolling pin installed a second side of the body.  
   
   
       3 . The suction brush of  claim 2 , wherein the first side is opposite the second side.  
   
   
       4 . The suction brush of  claim 2 , wherein at least one dust guide groove is configured to be formed at the bottom of the body to guide debris and air to the at least one suction port.  
   
   
       5 . The suction brush of  claim 4 , wherein the first and second rolling pins are respectively installed proximate to opposite ends of the at least one dust guide groove.  
   
   
       6 . The suction brush of  claim 1 , wherein the at least one rolling pin comprises: 
 a cylindrical portion configured to contact a surface to be cleaned, thereby spacing the bottom of the body from the surface to be cleaned; and    at least one coupling projection configured to project from opposite ends of the cylindrical portion and configured to be rotatably connected to the bottom of the body.    
   
   
       7 . The suction brush of  claim 1 , wherein the at least one rolling pin comprises a groove formed along the periphery thereof.  
   
   
       8 . The suction brush of  claim 7 , wherein the groove includes at least one spiral portion.  
   
   
       9 . A vacuum cleaner, comprising: 
 at least one suction brush;    at least one dust collector; and    means for separating the at least one suction brush from a surface to be cleaned.    
   
   
       10 . The vacuum cleaner of  claim 9 , wherein the means for separating includes at least one rolling pin.  
   
   
       11 . The vacuum cleaner of  claim 9 , further comprising at least one guide groove configured to guide dust attracted by the at least one suction brush to the at least one dust collector.  
   
   
       12 . The vacuum cleaner of  claim 11 , wherein the at least one guide groove is configured to be formed proximate to a bottom of the at least one suction brush.  
   
   
       13 . The vacuum cleaner of  claim 12 , wherein the means for separating is formed proximate to the at least one guide groove.  
   
   
       14 . The vacuum cleaner of  claim 11 , wherein the means for separating is formed proximate to the at least one guide groove.
