发明名称 BALANCED FLOW VACUUM CLEANER CONDUITS
摘要 An apparatus and method for transporting a flow of air and particulates through a vacuum cleaner. The apparatus can include an airflow propulsion (200) device that draws the flow through an intake aperture (111) and propels the flow through two upwardly-extending conduits (30) toward a filter element (80) housed in a filter housing (70). The conduits (30) can have generally smooth internal walls and a combined flow area less than the flow area of the intake aperture (111) to accelerate the flow upwardly toward the filter element (80).
