Abstract

The disclosure discloses a cyclonic separator and a cleaning appliance. The cyclonic separator includes a cyclonic separating drum and a centripetal force redirecting duct. The cyclonic separating drum has an upper side edge that communicates with a tangential air duct, through the tangential air duct, air with particles is guided to form an airflow consistent with a direction of the tangential air duct and tangentially enters the cyclonic separating drum to form a rotating airflow. The centripetal force redirecting duct is arranged in an upper portion of the cyclonic separating drum and communicating with the tangential air duct, such that after the rotating airflow enters the centripetal force redirecting duct, a direction of a centripetal force of the rotating airflow is changed to above a side of a direction of a support force of a drum wall of the cyclonic separating drum.
