Abstract
A cleaning assembly for a pipe. The assembly comprises a sleeve, at least one magnet, and at least one moveable hollow member. The sleeve is moveably disposed on the outer wall of the pipe. The at least one magnet is disposed on the inner surface of the sleeve. The at least one moveable hollow member conforms to the profile of the pipe's interior and is disposed in the interior of the pipe and is metal. When an external force acts on the sleeve along the longitudinal axis of the pipe, the at least one moveable hollow member moves with the sleeve by means of magnetic attraction to clean condensed powder from the pipe.
