Suction brush for a vacuum cleaner

Abstract

A suction brush for a vacuum cleaner including a body, the bottom side of which is formed with a suction port; a cover for covering the top side of the body; and an air jetting path for absorbing ambient air from the bottom side of the body and jetting the air toward a surface to be cleaned, to space the bottom side from the surface to be cleaned.

1 . A suction brush for a vacuum cleaner comprising: 
 a body including a bottom side with a suction port disposed therein;    a cover for covering a top side of the body; and    an air jetting path configured to absorb ambient air from the bottom side of the body and jet the air toward a surface to be cleaned, to space the bottom side from the surface to be cleaned.    
   
   
       2 . A suction brush as claimed in  claim 1 , wherein the body comprises an inflow opening formed remote from the suction port, and at least one jetting hole formed around the suction port, and the air is introduced into the air jetting path through the inflow opening and discharged through the at least one jetting hole.  
   
   
       3 . A suction brush as claimed in  claim 2 , wherein the body is formed with a dust guide groove in the bottom side thereof to guide air from the front and lateral sides of the body to the suction port, and plural jetting holes are formed along the dust guide groove.  
   
   
       4 . A suction brush as claimed in  claim 1 , wherein the body comprises a bottom panel having a dust guide groove to guide dust-laden air from the front and lateral sides of the body to the suction port, and a top panel interposed between the bottom panel and the cover, and 
 wherein the top and bottom panels are spaced from each other, thereby forming an air suction gap for introducing air from a lower side of the suction brush, and the bottom panel having plural jetting holes formed along side portions of the dust guide groove.    
   
   
       5 . A suction brush as claimed in  claim 4 , wherein the air jetting path is an air path for discharging the air introduced through the air suction gap through the plural jetting holes via a space formed between the top and bottom panels.  
   
   
       6 . A suction brush as claimed in  claim 4 , wherein the air suction gap is located at a position higher than that of the bottom side of the bottom panel.  
   
   
       7 . A suction brush for a vacuum cleaner, comprising: 
 a body, including:    a suction port providing access to an air suction path,    an inflow opening remote from the suction port,    a plurality of jetting holes, and    an air jetting path defined between the inflow opening and the plurality of jetting holes, whereby the air jetting path is separate from the air suction path.    
   
   
       8 . A suction brush as claimed in  claim 7 , wherein air flowing through the air jetting path travels in a direction generally opposite to the air traveling in the air suction path.  
   
   
       9 . A suction brush as claimed in  claim 7 , wherein the body includes a dust guide groove in a bottom side thereof to guide air from sides of the body to the suction port.  
   
   
       10 . A suction brush as claimed in  claim 7 , wherein the body includes first and second panels, one of the first and second panels being wider than the other thereby defining an air suction gap therebetween.  
   
   
       11 . A suction brush as claimed in  claim 10 , wherein the air jetting path discharges air introduced through the air suction gap through the jetting holes.
