Multiple cyclonic dust collector

Abstract

The multiple -cyclonic dust collector includes one first cyclone unit, several second cyclone units, one dust collecting tub and one casing. The first cyclone unit sucks air from outside and collects dust for the first time; the second cyclone units around the first cyclone unit and connected to the first cyclone unit collects fine dust from the air the first cyclone unit separates out; the dust collecting tub connected to the bottoms of the second cyclone units collects the fine dust the second cyclone units separates out; and the casing holds the first cyclone unit, the second cyclone units and the dust collecting tub for separating them from outside and has at least one angled part.

Description

technical field [0001] The invention relates to a multi-cyclone dust collecting device, in particular to a secondary cyclone dust collecting part distribution mechanism. Background technique [0002] In general, a cyclone dust collection device is a dust collection device that uses the principle of a cyclone to remove dust, dust, etc. (hereinafter "foreign matter") contained in the air, and is mainly suitable for vacuum cleaners. Recently, in order to improve dust collection performance, a multi-cyclone dust collector (Multi Cyclone Collector) in which a plurality of cyclone dust collectors are connected is used. [0003] Embodiment 1 of this multi-cyclone dust collecting device starts from Japanese Utility Model Publication No. 52-14775 and the like. [0004] refer to figure 1 and figure 2 , illustrate existing multi-cyclone dust collection device, as follows: [0005] The multi-cyclone dust collection device consists of a cyclone part 1 (hereinafter referred to as "pr...

AI Technical Summary

Problems solved by technology

Therefore, without increasing the size of the overall multi-cyclone dust collector, the number of secondary cyclone dust collectors 3 cannot be increased.

[0023] For this reason, the fine foreign matter that is not completely separated from the primary cyclone dust collection part 1 cannot be collected to the above-mentioned secondary cyclone dust collection part 3 to the greatest extent, thereby causing the suction fan (accompanying drawing) to have a vacuum cleaner through the discharge pipe 54 omitting) space discharge part of the problem

[0024] Moreover, when the existing multi-cyclone dust collection device is viewed on a plane, it needs to be formed into a circular shape as a whole

[0025] However, the internal space of a vacuum cleaner in which multiple cyclone dust collection devices are usually placed is probably formed into a square shape with predetermined corners. Empty corners end up wasting space
