Electric vacuum cleaner

Abstract

An electric vacuum cleaner includes an inlet port through which a suctioned air stream including dirt particles pass and a centrifugal separation member having a substantially circular space therein. The centrifugal separation member has a swirl portion to swirl the dust-laden suction air stream along an inner surface of the centrifugal separation member. By forming swirl passageway between the swirl portion and the inner surface of the centrifugal separation member, the high velocity swirling air stream can be made and consequently an efficiency of separating the dirt particles from the suction air and collecting the dirt particles can be improved.

Description

technical field [0001] The invention relates to a dust collecting structure of an electric vacuum cleaner. Background technique [0002] first pass Figure 7 The structure of a conventional electric vacuum cleaner will be described. This vacuum cleaner is provided with a dust collection chamber 31 with a bottom, and the side wall of the dust collection chamber 31 is provided with an air suction port 32 for sucking air inward along a tangential direction. A cover 34 is provided on the upper opening 33 of the dust collecting chamber 31 , and an exhaust port 35 is provided on the cover 34 . A filter screen 36 is also installed on the upper opening 33 of the dust collecting chamber 31 . When the electric fan 37 is working, the dust is inhaled from the suction head 38, sucked into the dust collection chamber 31 from the suction port 32, and is centrifugally separated in the dust collection chamber 31, and the exhaust gas is discharged from the exhaust port 35 after passing thro...

Problems solved by technology

However, in this way, the volume of the dust collection chamber 31 itself will also increase, resulting in the problem that the size of the electric vacuum cleaner will also increase.
