Abstract

A descaling brush has a handle; a plurality of bristles formed on the handle; and fine particles fixed at distal ends of the bristles. The fine particles are made of high hardness and rigidity material such as diamond, CBN, Aluminum Oxide, or Silicon carbide.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A descaling brush, comprising: 
 a handle ( 10 );    a plurality of bristles ( 11 ) formed on the handle ( 10 ); and    fine particles ( 12 ) of high hardness and rigidity fixed at distal ends of the bristles ( 11 ).    
     
     
         2 . The descaling brush as claimed in  claim 1 , wherein the fine particles ( 12 ) are made of diamond.  
     
     
         3 . The descaling brush as claimed in  claim 1 , wherein the fine particles ( 12 ) are made of Cubic Boron Nitride.  
     
     
         4 . The descaling brush as claimed in  claim 1 , wherein the fine particles ( 12 ) are made of Aluminum Oxide.  
     
     
         5 . The descaling brush as claimed in  claim 1 , wherein the fine particles ( 12 ) are made of Silicon Carbide.  
     
     
         6 . The descaling brush as claimed in  claim 1 , wherein the sizes of the particles are between 20 to 400 meshes per square inch.  
     
     
         7 . A method for manufacturing a descaling brush, comprising steps of: 
 fixing the particles ( 12 ) on distal ends of the bristles ( 11 ); and embedding the bristles ( 11 ) in the handle ( 10 ).    
     
     
         8 . The method for manufacturing the descaling brush as claimed in  claim 7 , wherein the particles ( 12 ) are fixed on the bristles ( 11 ) by solder.  
     
     
         9 . The method for manufacturing the descaling brush as claimed in  claim 7 , wherein the particles ( 12 ) are fixed on the bristles ( 11 ) by means of electroplating.  
     
     
         10 . The method for manufacturing the descaling brush as claimed in  claim 7 , wherein the particles ( 12 ) are fixed on the bristles ( 11 ) by resin.
