Cyclone collector for vacuum cleaner

Abstract

A cyclone dust collector for a vacuum cleaner, comprising a cyclone dust collector body (1, 11, 31), for sucking pollutants and air into the polluted air in the cyclone dust collector body (1, 11, 31) Inlet (2, 12, 32), air outlet (4, 13, 33) for discharging the air purified in the cyclone dust collector body (1, 11, 31), and for connecting with the cyclone dust collector The pollutant outlet (5, 14, 34) from which the pollutants separated by the body (1, 11, 31) are discharged, is characterized in that the cyclone dust collector body (1, 11, 31) includes a flow guiding device (7, 17, 37; 8, 18, 38), the device is arranged relative to the air outlet (4, 13, 33), thereby improving the vortex force in the cyclone dust collector body (1, 11, 31) and preventing the vortex The airflow and exhaust airflow interfere with each other.

Description

technical field [0001] The present invention relates to a cyclone dust collector, more particularly, to a cyclone dust collector suitable for vacuum cleaners. Background technique [0002] Generally, a cyclone dust collector is a device that collects pollutants such as dust, fluff, and paper scraps contained in the air by using the principle of a cyclone, and the cyclone dust collector is used in various fields, and is mainly used in household vacuum cleaners. [0003] Various types of cyclone dust collectors are proposed in documents such as US Patent 4643748, US Patent 4353008, US Patent 5078761, US Patent 145499 and the like. [0004] There are two types of cyclones: a forward direction cyclone in which the air containing pollutants (polluted air) is introduced in approximately the same direction as the purified air is discharged; and a A reverse cyclone dust collector, wherein the directions are different. [0005] A prior art unidirectional c...

AI Technical Summary

Problems solved by technology

[0022] First of all, because the polluted air sucked into the cyclone dust collector cannot get enough centrifugal force, the pollutants will not be collected effectively, but will be discharged to the outside of the cyclone dust collector together with the exhaust air, thus reducing the collection efficiency. dust efficiency

[0023] Secondly, the vortex airflow and exhaust airflow formed in the cyclone dust collector interfere with each other and generate flow resistance, thereby increasing the pressure loss and noise

This problem is especially serious in reverse cyclone dust collectors
