Multiple cyclonic dust collector

Abstract

The multiple cyclonic dust collector includes one first cyclonic dust collecting device to suck air from outside and separate foreign matters from the sucked air for the first time, secondary cyclonic dust collecting devices set around and connected to the first cyclonic dust collecting device to separate fine foreign matters from the air separated in the first cyclonic dust collecting device, and one dust collecting barrel set below the secondary cyclonic dust collecting devices the to suck the separated foreign matters from the secondary cyclonic dust collecting devices. The present invention has improved dust collecting barrel structure with less rotating flow of fine dust inside the dust collecting barrel and maximized dust collecting space.

Description

technical field [0001] The invention relates to a multi-cyclone dust collecting device. Background technique [0002] Generally speaking, a cyclone dust collection device is a device that uses the principle of a cyclone to suck in dust and dust contained in the air (hereinafter referred to as "foreign matter"), and is mainly suitable for vacuum cleaners. Recently, in order to improve the dust collection performance, a multi-cyclone dust collector (Multi Cyclone Collector) composed of a plurality of cyclone parts is generally used. [0003] An embodiment of such a multi-cyclone dust collecting device is documented in Japanese Application Model Publication No. 52-14775. [0004] Combining Figure 1 and figure 2 The existing multi-cyclone dust collection device is described in detail as follows. [0005] The multiple dust collection device is composed of a primary cyclone dust collection part 1 that sucks polluted air from the outside and then sucks relatively large dust, and...

AI Technical Summary

Problems solved by technology

[0023] Certainly, in order to prevent the dust inhaled in the above-mentioned dust collecting bucket 4 from splashing again, the space intervals connected with each second cyclone dust collecting part 3 can be divided and formed respectively, which not only has the problem of manufacturing difficulty, but ...
