Patent ID: 7269874

Claim:
A cleaning device ( 100 ) for cleaning a generally elongated duct or pipe, comprising: a housing ( 120 ) of generally cylindrical appearance having a front end ( 124 ) and a rear end ( 126 ); an inner-drum ( 300 ) having a front end ( 340 ), a rear end ( 360 ), a sidewall ( 380 ), and a sidewall inner-surface ( 400 ), wherein said inner-drum ( 300 ) is located inside said housing ( 120 ); a drive shaft ( 320 ) protruding from said rear end ( 360 ) of said inner-drum ( 300 ) and through said rear end ( 126 ) of said housing ( 120 ); a cable ( 180 ) abutting against said inner-surface ( 400 ) of said inner-drum ( 300 ), wherein said cable ( 180 ) has opposite proximal ( 200 ) and distal ( 220 ) ends, wherein during normal operation said distal end ( 220 ) protrudes through said front end ( 340 ) of said inner-drum ( 300 ) and through said front end ( 124 ) of said housing ( 120 ); and a cleaning member ( 240 ), wherein said cleaning member ( 240 ) is attachable to said distal end ( 220 ) of said cable ( 180 ), wherein rotation of said drive shaft ( 320 ) causes rotation of said inner-drum ( 300 ), and wherein rotation of said inner-drum ( 300 ) causes said distal end ( 220 ) of said cable ( 180 ) to rotate thereby rotating said cleaning member ( 240 ) when fitted to said distal end ( 220 ) of said cable ( 180 ).
