Inner core acceleration type cyclone separator

Abstract

The invention discloses an inner core accelerated cyclone separating device used for a vacuum cleaner. The inner core accelerated cyclone separating device comprises an external cyclone chamber used for separating dust from air with dust, a first dust collection chamber which is encircled by the external cyclone chamber, a central cone-shaped accelerator having the same axis with the external cyclone chamber, a second collection chamber collected with the output of the central cone-shaped accelerator, a water droplet-shaped deflector in the cyclone separating device used for enhancing the efficiencies of the pumping and dust collection, a dust ring and a reflective screen. The air flow with dust entering the cyclone separating device is rotated only once, and the thick ash is separated by the external cyclone chamber into the first dust collection chamber, the core of the cyclone region has air flow with small dust particles; after being further accelerated by the droplet-shaped deflector and the central cone-shaped accelerator, the thin dust is separated and is stored into the second collection chamber, therefore, compared with a twin dust collector, the inner core accelerated cyclone separating device reduces the energy loss of air flow with dust, achieves greater air volume and obtains better pumping and dust collection efficiencies.

Description

technical field [0001] The invention relates to a cyclone separator and a vacuum cleaner having said cyclone separator. Background technique [0002] Typically, a cyclone separator creates a vortex in the cyclone chamber to separate dust and dirt by centrifugal force. Examples of such cyclone separators for vacuum cleaners are disclosed in US Patent Nos. 3,425,192 and 4,373,228 and 4,571,772 and 4,593,429; [0003] In the aforementioned patent, a conventional cyclone separator and dust collector is used, which utilizes a two-stage cyclone separator to separate dust from dust-laden air. In the above structure, most of the large dust particles or dirt and part of the fine dust are separated at the first cyclone, and the air from which the dust is separated flows into the second stage cyclone or the auxiliary cyclone to separate the fine dust Dust particles or dirt, however, conventional vacuum cleaners have the following disadvantages: [0004] First of all, the two-stage c...

AI Technical Summary

Problems solved by technology

[0009] In order to achieve the above-mentioned purpose of the present invention, aiming at the problem of low cyclone angular velocity, high turbulence intensity, and poor filtering effect of fine particle dust in the first-stage cyclone vacuum cleaner, the core area of ​​the cyclone is continuously accelerated to improve the separation effect of fine dust particles, while avoiding In the two-stage cyclone filter structure of the existing vacuum cleaner, it is necessary to consume a lot of energy for the dust-laden airflow to perform two rotation accelerations, so that ordinary vacuum cleaners can save 10-20% of power
