Abstract

The utility model relates to a vacuum cleaner dust bag arranged in body of the vacuum cleaner and comprises an inner bag core and an outer bag body wrapping the inner bag core. The outer bag body is folded to surround periphery of the inner bag core. As the outer bag body of the dust bag is folded to surround the periphery of the inner bag core, when in ventilation and filtering, the outer bag body is spread by air to be filtered, and dust filtering area acquired greatly exceeds that of prior cylinder type filter bag, thus achieving better filtration effect.

Description

The dust catcher dust settling pocket

Technical field

The utility model relates to a kind of dust arrester of dust catcher, especially a kind ofly is installed in the dust settling pocket that dust catcher inside is used for the air that has dust that sucks is carried out filtration treatment.

Background technology

The existing dust settling pocket that is installed in dust catcher inside mostly is cylindrical structure, and after the air that has dust that sucks from air inlet entered dust settling pocket, dust was intercepted by bag, falls into bag, and cleaned air passes is discharged from from air outlet again.Yet under the prerequisite of identical filter area, the cylindrical shape filter bag must occupy bigger space.Therefore the dust catcher producer just need make awkward selection between small product size increase and poor filtration effect.

Summary of the invention

The purpose of this utility model is that the area that takes up room that exists at existing cylindrical shape dust settling pocket is big, and the deficiency that efficiency of dust collection is low is provided at the novel dust removing bag that can obtain bigger filter bag area under the same space area.

The technical solution of the utility model is: a kind of dust settling pocket of dust catcher, be arranged on the internal body of dust catcher, and comprise an inner bag core and surround the outer bag of inner bag core that described outer bag is looped around inner bag core periphery for folding.

The beneficial effects of the utility model are: because the outer bag of dust settling pocket is looped around inner bag core periphery for folding, therefore when ventilating filtration, wind to be filtered struts outer bag, and the filter dirt area that is obtained just is far longer than existing drum type brake filter bag, thereby obtains better filter effect.

Description of drawings

Fig. 1 is the structural representation of the dust settling pocket of the utility model specific embodiment;

Fig. 2 is the dust settling pocket sectional structure schematic diagram of the utility model specific embodiment.

The specific embodiment

To specific embodiment of the utility model shown in Figure 2, a kind of dust catcher dust settling pocket comprises an inner bag core 1 and the outer bag 2 that surrounds the inner bag core as Fig. 1, and described outer bag 2 is looped around inner bag core 1 periphery for folding.

During use, the air that has dust is after the air inlet of dust catcher enters, in the feeding dust settling pocket, wind-force makes dust settling pocket air-blowing in certain limit, obtain bigger dedusting area, dust is attracted on the outer bag, is passed in other evolution devices through the preliminary wind that cleans further to purify again, be excluded at last, the dust in the dust settling pocket then is collected into unified processing the in the dust bucket.

Claims (1)

1. dust catcher dust settling pocket is arranged on the internal body of dust catcher, it is characterized in that: comprise an inner bag core and surround the outer bag of inner bag core, described outer bag is looped around inner bag core periphery for folding.
