CYCLONE-TYPE DUST-COLLECTING APPARATUS FOR VACUUM CLEANER

摘要

A cyclone-type dust collecting apparatus having a dust removing portion for removing from the grill portion the dust and foreign substances that become attached to the grill portion of the grill member while the grill portion is rotated by the vortex air of the cyclone body. The dust removing portion includes rotating means disposed at a lower portio n of the grill member for rotation by an air current passing therethrough; a rotary member rotatably connected to the rotating means, and disposed separate from an end of the grill member by a predetermined distance; and a brush member having one side connected to the rotary member and the other side being disposed in contact with the grill portion of the grill member for removing the dust and foreign substances from the grill portion. As the cleaning operation starts, the brush member inside of the cyclone-type dust collecting apparatu s is rotated by the vortex current generated therein, to remove dust or contaminants from the grill portion of the grill member. Accordingly, clogging of the gull portion of the grill member is prevented, and as a result, deterioration of the suction force and overload of the motor ca n be inhibited.
