PURPOSE:To surely remove hard deposits, if any, in a pipeline by attaching hard terminal means to the front end of a flexible outside pipe and cleaning the pipeline and to efficiently remove the soft deposits in the pipeline by projecting many expanded wires from an outside pipe and cleaning the pipeline if there are no hard deposits. CONSTITUTION:This cleaning means includes the flexible outside pipe 2 and an inside cord 3 slidably inserted therein. The terminal means 2b, 2c consisting of hard materials are mounted at one end of the outside pipe 2. The inside cord 2 is made of a twisted wire formed by doubling and twisting plural strands and is connected with a handle 4 at its one end. The other end is expanded to an approximately circular conical shape by unraveling the twisted wire. The expanded part of the inside cord 3 is retreated into the terminal means 2b, 2c when the inside cord 3 is retreated by operating the handle 4. The hard deposits are surely removed by the hard terminal means 2b, 2c when the terminal means come into contact with the hard deposits. The soft deposits are efficiently the end of the inside cord in case of the soft deposits. |
