Cyclone type dust collecting apparatus of vacuum cleaner

Abstract

The device has a lower body (40) to centrifuge and collect large size foreign substances contained in air sucked from outside. An upper body (30) is arranged in an upper part of the body (40) and has an inlet hole (31). The body (30) centrifuges and collects small size foreign substances contained in the air blown back from the body (40), in the order of sizes of the substances.

Description

technical field [0001] The present invention generally relates to a cyclone-type dust collection device for a vacuum cleaner, and more particularly to a dust collection device with two cyclones, wherein dust-containing impurities in the airflow are collected by multiple centrifugation processes. Background technique [0002] Such as figure 1 As shown, the traditional cyclone dust collecting device 100 includes a cyclone body 110 and a filter 130 disposed in the cyclone body 110 . Reference numeral 3 indicates the main body of the vacuum cleaner ( figure 2 ). The cyclone dust collecting device 100 is provided in the receiving portion 10 of the main body 3 . The main body 3 is provided with an inlet connection pipe 13 ( figure 2 ) and the outlet connecting pipe 14 to introduce the air containing impurities into the cyclone dust collecting device 100. Outlet connecting pipe 14 ( figure 2 ) to discharge the purified air, wherein the impurities in the purified air have b...

AI Technical Summary

Problems solved by technology

Therefore, the smooth flow of the airflow is disrupted and noise is generated

In case the airflow contains many impurities, it is difficult to fully utilize the filtering function of a single filter installed in a conventional cyclone dust collector

Also, it is inconvenient since the filter needs to be changed frequently
