Multiple cyclonic dust collector

Abstract

The multiple cyclonic dust collector includes one primary cyclonic dust collecting device with first air inflow unit, the first main body to separate out foreign matters from the inflow air, one dust collecting tub set in the side bottom of the first main body to collect the foreign matters the first main body separates out, one extending unit extending from the bottom of the first main body and set inside the dust collecting tub, and the first air outflow unit for air to flow out of the first main body; and one secondary cyclonic dust collecting device installed outside the primary cyclonic dust collecting device to suck air from the primary cyclonic dust collecting device for secondary dust collection.

Description

technical field [0001] The invention relates to a cyclone dust collecting device. More specifically, the present invention relates to the invention of a multi-cyclone dust collector that connects a plurality of cyclone dust collectors. Background technique [0002] Generally speaking, a cyclone dust collector is a device that uses the principle of cyclone separation to separate and collect dust (hereinafter referred to as "foreign matter") contained in the air. Here, the above-mentioned cyclone dust collecting device is mainly applied to a vacuum cleaner. [0003] Recently, in order to further improve the dust collection performance, a multi-cyclone dust collector (Multi Cyclone Collector) that connects multiple cyclone dust collectors has appeared on the market. [0004] Here, the above-mentioned multi-cyclone dust collector is composed of the following components: an upstream cyclone dust collector (upstream cyclone) that collects dust with a large dust volume after inha...
