摘要

PURPOSE: A separation plate for a dust collecting casing of a vacuum cleaner and the dust collecting casing using the same are provided to improve the efficiency of dust collection by preventing foreign bodies in the dust collecting casing from flowing upward. CONSTITUTION: Air including foreign bodies is introduced into a casing unit(110), and the casing unit has an inlet forming swirl. A cover(130) has a cylindrical filter(132) in the lower center, and is installed at the top of the casing unit. A separation plate(120) has an air hole(126) connected to the lower end of the filter, a guiding hole, and a back flow preventing unit(124) in the lower part of the guiding hole. An outlet(118) discharges the air passing through the filter and the air hole.
