Multiple cyclonic dust collector

Abstract

A multi-cyclone dust collection device, including a primary cyclone dust collection part that sucks in external air and foreign matter at one time; and is connected with the primary cyclone part and sucks fine foreign matter again from the air that has separated foreign matter at one time The cyclone dust collection part is small and a plurality of second cyclone dust collection parts are formed along the outer periphery of the primary cyclone dust collection part; The dust part is composed of a dust collection bucket that sucks the separated fine foreign matter in the air. The invention improves the structure of the dust collecting barrel of the second dust collecting part to reduce the swirling flow of fine dust in the dust collecting barrel while maximizing the new structure of the 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] combine figure 1 with 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, an...

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 also only has the same effect as any one cyclone dust collecting part. The allowable dust collection capacity can only be exceeded if the space is connected to each other, so there is still a problem that the probability of the fine dust sucked into the corresponding space becoming splashed again becomes larger.
