发明名称 Floor cleaning tool for vacuum cleaner
摘要 A plastic floor cleaning tool for a vacuum cleaner is characterized by two injection molded plastic pieces that are joined to form an integral structure. By using two plastic pieces to form the floor tool, each may be injection molded to a configuration such that, when they are joined, the floor tool has an aerodynamically shaped interior air flow chamber. The aerodynamically shaped chamber improves the air flow through the floor tool, so that a powerful vortex action is generated at floor level, suction is intensified and debris is aerodynamically airswept through smooth, contoured channels in the floor tool at full force and without encountering acute bends in the air flow path.
