Abstract

The utility model discloses a cyclone dust extractor for vacuum cleaners which comprises a cyclone arranged inside a dust cup, a cyclone air inlet and a fallout port are arranged on the cyclone, a plurality of reflux keyholes are arranged on the lateral wall of the cyclone; the air and the fine dust inside the dust cup of the utility model can enter the cyclone by the reflux holes, therefore the influence of the dust removal effect caused by the excessive wind pressure in the dust cup can be avoided.

Description

The cyclone dust collector of dust catcher

Technical field

The utility model relates to a kind of cyclone dust collector of dust catcher.

Background technology

In traditional dust catcher filter is installed, purpose is that the dirty air that will suck filters, therefore dust granule is stayed in the dust collect plant,, this type of dust catcher is after using a period of time, the user should clear up filter or change, otherwise, after the filter opening of filter is stopped up by thin dust, can increase the resistance of vacuum motor, severe patient even can burn out motor has not only brought trouble to the user, and can influence the performance and the life-span of dust catcher.

In recent years, manufacturer substitutes filter with cyclone and filters dirt according to the principle of cyclonic separation, has obtained dust removing effects preferably, therefore is widely applied on the dust catcher.This cyclone is provided with a whirlwind tube in the dirt cup, the whirlwind tube is provided with whirlwind air inlet and air outlet, during use, after the air that has a dust enters the whirlwind tube, dust separates under the whirlwind effect with air, clean air is discharged through air outlet, dust then under action of centrifugal force the dust fall mouth by sidewall converge in the dirt cup outside the whirlwind tube.

But because the dirt cup of whirlwind tube outside seals, so in use, the blast in the dirt cup can be more and more higher, and then influence dust and enter the dirt cup from the dust fall mouth, reduced dust removing effects.

Summary of the invention

The purpose of this utility model is: a kind of cyclone dust collector of dust catcher is provided, and this device is provided with the backflow aperture on the whirlwind tube, can reduce the blast in the dirt cup, improves the dust collecting effect of dirt cup.

The technical solution of the utility model is: a kind of cyclone dust collector of dust catcher, comprise the whirlwind tube that is installed in the dirt cup, the whirlwind tube is provided with whirlwind air inlet and dust fall mouth, the sidewall of described whirlwind tube is provided with several backflow apertures, and the backflow aperture enters in the whirlwind tube along the direction of whirlwind.

The further technical scheme of the utility model is: a kind of cyclone dust collector of dust catcher, comprise the whirlwind tube that is installed in the dirt cup, and the whirlwind tube is provided with whirlwind air inlet and dust fall mouth, and the sidewall of described whirlwind tube is provided with several backflow apertures; Described backflow aperture is positioned at the offside of dust fall mouth.

The more detailed technical scheme of the utility model is: a kind of cyclone dust collector of dust catcher, comprise the whirlwind tube that is installed in the dirt cup, and the whirlwind tube is provided with whirlwind air inlet and dust fall mouth, and the sidewall of described whirlwind tube is provided with several backflow apertures; The described whirlwind tube of the offside that described backflow aperture is arranged in the dust fall mouth is horizontal at the dirt cup, and disposal box is positioned at the Lower Half of dirt cup, and dust fall mouth and backflow aperture lay respectively at two side lower parts of dirt cup, are communicated with disposal box.

The utility model has the advantages that:

1. because the utility model is provided with the backflow aperture on the whirlwind tube, therefore, air in the dirt cup and fine dust can enter into the whirlwind tube by return port, thereby can avoid because of the too high phenomenon that influences dust removing effects of the blast in the dirt cup.

2. though air in the whirlwind tube and part fine dust can be discharged by air outlet, they can not enter into the room air contaminated environment under the filtration of sea, rear portion handkerchief.

Description of drawings

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 8 is a right view of the present utility model.

Wherein: 1 dirt cup; 2 whirlwind tubes; 3 whirlwind air inlets; 4 dust fall mouths; 5 backflow apertures; 6 disposal boxes.

The specific embodiment

Embodiment: as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, a kind of cyclone dust collector of dust catcher, comprise dirt cup 1, be horizontally installed with whirlwind tube 2 in the dirt cup 1, the Lower Half of dirt cup 1 is provided with disposal box 6, the leading section of whirlwind tube 2 is provided with whirlwind air inlet 3, air outlet is arranged in the rear portion (figure does not draw) of whirlwind tube 2, the two side of whirlwind tube 2 is respectively equipped with dust fall mouth 4 and backflow aperture 5, backflow aperture 5 enters in the whirlwind tube 2 along the direction of whirlwind, and dust fall mouth 4 and backflow aperture 5 are communicated with disposal box 6 respectively.

During use, the air that contains dust enters into whirlwind tube 2 from whirlwind air inlet 3, and generation rotation in whirlwind tube 2, cinder dirt is pooled to the dirt cup 1 from dust fall mouth 4 under action of centrifugal force, air in the dirt cup 1 and can from the backflow aperture 5 of opposite side, be back in the whirlwind tube 2 by the fine dust that whirlwind is brought into, make whirlwind tube 2 and dirt cup 1 form the circulation that an air flows, therefore, can avoid because of the too high phenomenon that influences dust removing effects of the blast in the dirt cup 1, the tiny dust of a cleaned air and a part is discharged from the air outlet of whirlwind tube, and fine dust can not enter into room air under the extra large handkerchief at rear portion filters.
