Abstract

The present invention relates to a dust separating device for vacuum cleaners, which comprises a first separator 17 and a cyclone separator 14, wherein the first separator 17 comprises an upstream dust chamber 7 and an airflow distribution chamber 18; the upstream dust chamber 7 is provided with a dust air inlet 2; the airflow distribution chamber 18 is provided with a first airflow outlet 13 and a second airflow outlet 16; the second airflow outlet 16 is provided with a first filter 5; the cyclone separator 14 is provided with a cyclone inlet 12 and a cyclone outlet 4; the first airflow outlet 13 is communicated with the cyclone inlet 12. After large dust is separated by the first separator from parts of airflow, the airflow directly flows out from the second airflow outlet, and thereby, the present invention decreases the flow quantity of the airflow which enters the cyclone separator, enhances the cyclone separating effect of the cyclone separator, and increases the flow quantity of the airflow in the whole separating device.

Description

Dust-separating appliance on the dust catcher

Technical field

The present invention relates to the dust-separating appliance on a kind of dust catcher.

Background technology

Dust-separating appliance on the existing dust catcher generally includes first separator and downstream separator, wherein, downstream separator is a cyclone separator, band dirt air-flow carries out crude separation in first separator, make big ash be separated, the air-flow that enters in the downstream separator carries out high efficiency separation, make thin dirt be separated, because the separative efficiency of first separator is lower, so the separation of downstream separator burden is heavier, and because the air-flow that separates in first separator behind the big ash all enters in the downstream separator, so it is bigger to enter the flow of the air-flow in the downstream separator, this makes that the effect of cyclonic separation is relatively poor in the downstream separator, causes the efficiency of dust filtration of whole dust-separating appliance lower.

Summary of the invention

The object of the invention provides the dust-separating appliance on a kind of dust catcher, and it can reduce the flow that enters the air-flow in the downstream separator, the burden that alleviates downstream separator.

Technical scheme of the present invention is: the dust-separating appliance on a kind of dust catcher, it comprises first separator, be positioned at the cyclone separator of the described first separator sidepiece, described first separator comprises dirt chamber, upstream and gas distribution chamber, separate mutually with the mesh plate that has a plurality of mesh between dirt chamber, described upstream and the gas distribution chamber, dirt chamber, described upstream has dirt wind inlet, described gas distribution chamber has and first air stream outlet and second air stream outlet, described second air flow outlet is provided with first filter, have whirlwind inlet and whirlwind outlet on the described cyclone separator, described first air stream outlet is connected with the whirlwind inlet, and the air-out passage is directly led in described second air stream outlet and whirlwind outlet.

Described air-out passage is provided with second filter.

Between described first separator, the cyclone separator with dividing plate separately, the below of described cyclone separator has dirt chamber, downstream, dirt chamber, described downstream and dirt chamber, described upstream are also with dividing plate separately, the below of described dividing plate is provided with bottom, and described dividing plate and described bottom be sealed engagement mutually.

The present invention compared with prior art, has following advantage: on first separator, establish second air stream outlet in addition, make the air-flow of a part after first separator is isolated big ash directly to flow out from second air flow outlet, and through the filtration of first filter, and make the air-flow of discharging from second air flow outlet and the air-flow of discharging be all clean gas flow from the whirlwind exit of the cyclone separator in downstream, so just, can reduce to enter the air flow rate in the cyclone separator, improve its cyclonic separation effect, and because air-flow is discharged from two exits, so can increase the air-flow total flow in the whole separator, therefore the setting of second air stream outlet can improve the efficiency of dust filtration of this dust-separating appliance, strengthen its dust removal ability.
