Cyclone dust collecting unit for vacuum cleaner

Abstract

A cyclone dust collecting device of a vacuum cleaner, which is mounted on a telescopic extension pipe. The cyclone dust collecting device of a vacuum cleaner, includes a cyclone body for generating a swirling flow from air and contaminants drawn thereinto, and a cyclone housing engaged with the cyclone body and for separating the contaminant from the air by guiding the swirling flow. The cyclone housing includes a cyclone housing engaged with the cyclone body, for separating the contaminant by guiding the swirling air flow, a cyclone cover formed in a cylindrical shape and engaged with the cyclone body, one end of which being a slanted end closed by a spiral line, and the other end of which being an open end, and a dust collecting container engaged with a lower portion of the slanted end of the cyclone cover, one end of which substantially being a cylinder having one closed end, and the other end of which being slant to correspond to the slanted end of the cyclone cover. Accordingly, normal cleaning can be performed regardless of position of the vacuum cleaner, and, even when discarding collected contaminant, falling of the contaminants from a grill or the breakage of the grill can be prevented.

Description

technical field [0001] The present invention relates to vacuum cleaners, and more particularly to a cyclone dust collection device mounted on a telescoping extension tube of the vacuum cleaner to filter out and collect larger particles of dirt introduced into the vacuum cleaner. Background technique [0002] Generally speaking, cyclone dust collectors use centrifugal force to separate particles from fluid. Because of its simple structure and ability to withstand high temperature and high pressure environments, cyclone dust collectors have been widely used in industrial occasions for a long time. In addition, the cyclone dust collection device is also used in the vacuum cleaner to inhale the air through the cleaning brush, filter it and then collect larger particles of dirt, such as thin paper sheets, vinyl resin, fluff, etc. The cyclone dust collection device prevents these larger dirt from being filtered out through the paper filter and allows them to settle in the dust co...
