Suction apparatus for a vacuum cleaner

Abstract

A suction apparatus for a vacuum cleaner particularly designed for removing mites and dust from textile materials by suction. The apparatus comprises a cylindrical suction tube, which removably connects with a connecting tube for removable connection to an extension pipe of a vacuum cleaner. Movement guidance rollers installed bilaterally on the circumference of the suction tube provide free movement on a fibrous surface for the removal of mites and dust by suction during the use of a vacuum cleaner.

1 . A suction apparatus for a vacuum cleaner, comprising: 
 a hollow cylindrical suction tube;    at least one suction aperture formed in the lower part of the suction tube; and    at least one roller mounted for rotation on the suction tube and having a plurality of suction apertures on its surface.    
   
   
       2 . The apparatus of  claim 1  further comprising a friction member disposed at an outer circumference of the roller.  
   
   
       3 . The apparatus of  claim 2  wherein the friction member comprises a plurality of protrusions spaced about the circumference of at least one end of the roller.  
   
   
       4 . The apparatus of  claim 2  wherein the friction member comprises a plurality of protrusions spaced about the circumference of each of the inner and outer end portions of the roller.  
   
   
       5 . The apparatus of  claim 1  further comprising a rotating dust generating bar.  
   
   
       6 . The apparatus of  claim 5  wherein two rollers are disposed on either side of the center of the suction tube and the rotating dust generating bar is disposed in the suction tube between the rollers.  
   
   
       7 . The apparatus of  claim 1  wherein the rollers are removable from the suction tube.  
   
   
       8 . A suction assembly for a vacuum cleaner comprising: 
 a housing having a suction duct for the passage of dust;    a pair of rotation members rotatably disposed on either side of the housing;    at least one suction aperture in the housing;    a plurality of suction apertures in the surface of the rotation members; and    connection means for connecting the housing to a vacuum cleaner.    
   
   
       9 . The apparatus of  claim 8  further comprising a friction member disposed at an outer circumference of the roller.  
   
   
       10 . The apparatus of  claim 9  wherein the friction member comprises a plurality of protrusions spaced about the circumference of at least one end of each rotation member.  
   
   
       11 . The apparatus of  claim 9  wherein the friction member comprises a plurality of protrusions spaced about the circumference of each of the inner and outer end portions of each rotation member.  
   
   
       12 . The apparatus of  claim 8  further comprising a rotating dust generating bar.  
   
   
       13 . The apparatus of  claim 12  wherein the rotating dust generating bar is disposed in the housing between the rotation members and protrudes from the housing so as to contact a surface to be cleaned.  
   
   
       14 . The apparatus of  claim 12  wherein the rotating dust generating bar comprises a plurality of protrusions spaced about its circumference.  
   
   
       15 . The apparatus of  claim 8  wherein the rotation members are removable from the housing.  
   
   
       16 . The apparatus of  claim 8  wherein the rotation members are rollers.  
   
   
       17 . The apparatus of  claim 8  further comprising a connecting tube for connecting the suction tube to an extension pipe of a vacuum cleaner, the upper end of the connecting tube having an exterior slope with a fixed ratio so as to be capable of connecting with extension pipes of varying diameters.
