NOZZLE ASSEMBLY WITH AIR FLOW ACCELERATION CHANNELS

摘要

A nozzle assembly is provided for a suction cleaning device. The nozzle assembly includes a body having an edge and a bottom wall. The bottom wall includes an intake opening and a portion extending between the edge and the intake opening. At least one channel is provided within that portion. That channel extends between the edge and the intake opening and has a cross sectional area decreasing in a direction extending from the edge toward the intake opening. Air drawn through the channel is accelerated as i t approaches the intake opening in order to increase the dirt, dust and debris entraining capacity of that air and overall vacuum cleaner cleaning efficiency.
