Patent Images
1. A vacuum cleaner comprising:
- a nozzle section;
a cleaner body coupled to the nozzle section and being in fluid communication with the nozzle section;
a dust collecting container operatively coupled with the cleaner body;
a primary cyclone for separating dust and dirt from a suction airflow flowing into the dust collecting container;
at least one secondary cyclone disposed along a periphery of the primary cyclone for separating dust and dirt entrained in the airflow discharged from the primary cyclone;
a discharge member being centrally arranged in the primary cyclone for filtering the airflow prior to the airflow being discharged from the primary cyclone; and
a floatation prevention member attached to an underside of the discharge member for preventing swirling airflow in the dust collecting container.

Abstract
A vacuum cleaner includes a nozzle section, a cleaner body coupled to the nozzle section and being in fluid communication with the nozzle section, a dust collecting container operatively coupled with the cleaner body, a primary cyclone, a secondary cyclone, a discharge member arranged in the primary cyclone and a floatation prevention member. The primary cyclone and at least one secondary cyclone separate dust and dirt from a suction airflow flowing into the dust collecting container. The floatation prevention member is attached to an underside of the discharge member for preventing swirling airflow in the dust collecting container.
