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...

AI Technical Summary

Problems solved by technology

[0020] The 1st, in the multi-cyclone dust collecting device according to the prior art, the air flowing into the first main body 12 of the above-mentioned primary cyclone dust collecting part 1 will drop to the bottom of the first outflow part 14, so the dust has been collected The dust in the bottom space in the first main body 12 may be scattered again

[0021] Second, the air that has flowed into the first body 12 through the first inflow portion 11 will drop to the lower portion of the first outflow portion 14 and rise, and then be discharged to the outside of the first body 12 through the first inflow portion 11, Therefore, the problem of pressure loss will arise

This will reduce the suction efficiency

[0022] The 3rd, in the multi-cyclone dust collecting device according to the prior art, when the filter 16 that is arranged on the 1st outflow part 11 of primary cyclone dust collecting part 1 is clogged, will produce serious pressure loss phenomenon, therefore induce The reduction of suction force and the decline of dust collection performance
