Portable power pipe cleaning brush with plastic housing and improved durability

Abstract

The present invention relates to a portable power-driven pipe cleaning device designed for cleaning cylindrical materials, such as pipe ends, in preparation for soldering or brazing. The device comprises a cylindrical brush housed within a plastic housing, a shaft configured for attachment to a power drill, and a metal torque plate positioned inside or outside the housing. The torque plate features locking mechanisms that prevent relative rotation between the shaft and housing, ensuring reliable torque transfer. The torque plate's locking points are positioned at least 6.1 millimeters from the shaft axis, distributing stress and improving the housing's durability. The modular design allows for replaceable brushes and torque plates, accommodating various cleaning tasks. Optional features include protective coatings, gaskets, and venting to enhance performance and longevity. Combining durability, cost efficiency, and versatility, this invention overcomes the limitations of conventional designs, providing an effective and reliable solution for industrial and consumer applications.
