Abstract
The invention discloses a dust bag for a dust collector, which at least comprises an outer filter layer and an inner filter layer. The outer filter layer is located on the outer side of the dust bag, the inner filter layer is located on the inner side of the dust bag, the outer filter layer is separated from the inner filter layer, and when the dust bag is opened, a space is formed between the outer filter layer and the inner filter layer. The dust bag is simple in structure, gaps are arranged among multiple layers of filter materials assuredly, air can flow through the gaps, accordingly, the air quantity of the total dust collector after the dust collector collects dust is increased, and dust collection ability of the dust collector is maintained and not reduced.
Description
Technical field
The present invention relates to the dirt bag that a kind of dust catcher is used.
Background technology
Existing vacuum cleaner dust bag; The filtering material of its each layer is all smooth to spread out, and sucks that the filtering material of each layer is close together behind the dust, the layer that causes the dirt bag with layer filtering material between do not have the space allowing air flow; Cause the decline of complete machine air quantity easily, and then influence the performance of dust catcher.
Summary of the invention
The present invention seeks to: provide a kind of simple in structure and improve the dirt bag that the dust catcher of air quantity is used.
Technical scheme of the present invention is: the dirt bag that a kind of dust catcher is used; It comprises the outer filter course that is positioned at the outside at least and is positioned at inboard inner filtration layer; Be separated from each other between wherein outer filter course and the inner filtration layer, when the dirt bag opens, form the space between outer filter course and the inner filtration layer.
On the basis of technique scheme, further comprise following attached technical scheme:
The volume of filter course described in the present invention is less than the volume of said outer filter course.
Distance between outer filter course described in the present invention and the inner filtration layer is greater than 1mm.
The present invention also comprise outside filter course between filter course and the inner filtration layer.
Outer described in the present invention, inner filtration layer is nonwoven or paper.
Filter course described in the present invention is the filtering material of elasticity and porous.
Filter course described in the present invention is the plastic plate with micropore.
Advantage of the present invention is:
The present invention is simple in structure, guarantees to have between the multiple filtration material space to let air flow through, thereby improves the complete machine air quantity behind the suction dust, keeps dust-absorbing strength not descend.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is a cross-sectional schematic of the present invention;
Fig. 2 is a schematic perspective view of the present invention;
Fig. 3 is installed to the cross-sectional schematic in the dust catcher for the present invention;
Wherein: 10, vacuum chamber; 12, motor room; 20, dirt bag; 22, outer filter course; 24, filter course; 26, inner filtration layer; 30, dirt bag frame; 100, motor air inlet; 200, dirt bag sidewall; 202, space; 300, opening.
The specific embodiment
Embodiment: shown in Fig. 1-2; The invention provides the specific embodiment of the dirt bag that a kind of dust catcher uses, it comprise be positioned at the outside and allow outer filter course 22 that air flows out, be positioned in the middle of and allow the filter course 24 that air flows out, the inner filtration layer 26 that is positioned at the inboard and allows air to flow out.Be separated from each other between wherein outer filter course 22 and the inner filtration layer 26, distance between the two is at least greater than 1mm, and the volume of inner filtration layer 26 is less than the volume of said outer filter course 22.When the dirt bag fully opens, form three-dimensional space 202 between outer filter course 22 and the inner filtration layer 26, and make outer filter course 22 form the three-dimensional dirt bag that constitutes by several dirt bag sidewalls 200 in the outside.During use, air communication is crossed inner filtration layer 26, gets into space 202 very swimmingly, and enters into outer filter course 22 very swimmingly through this space 202, avoids existing inside and outside filter course to fit each other and the air-out that causes has some setbacks.Also can be provided with filter course 24 with time space 202, this filter course 24 is preferably to have certain flexible plastic material or deformable material is arranged, for example sponge, have micropore and folding plastic plate, the thickness of filter course 24 is greater than 1mm simultaneously.
It is understandable that the dirt bag also can include only two-layer, and filter course is positioned at the inboard, also can realize the object of the invention.
As shown in Figure 3, dirt bag 20 of the present invention is installed in the dust catcher, this dust catcher comprises the vacuum chamber 10 and the motor room 12 of accommodating dirt bag 20, and a motor air inlet 100 that is communicated with motor room 12 is wherein arranged in the vacuum chamber 10.During use; Filter course 24 supports outer filter course 22, makes outer filter course 22 and motor air inlet 100 maintenance spacings simultaneously, and guaranteeing has the space to let air flow through between 26 3 layers of the outer filter courses 22, filter course 24, inner filtration layer; Thereby improve the complete machine air quantity behind the suction dust, improve the performance of dust catcher.Certainly be further to improve air quantity; Between vacuum chamber 10 and dirt bag 20, be provided with a dirt bag frame 30; This dirt bag frame 30 is provided with several openings 300, enter into motor air inlet 100 to guarantee the air that dirt bag 20 flows out, and the dirt bag sidewall 200 of isolated dirt bag 20 contacts with vacuum chamber 10 madial walls.
The present invention is simple in structure, guarantees to have between the multiple filtration material space to let air flow through, thereby improves the complete machine air quantity behind the suction dust, keeps dust-absorbing strength not descend.
Certainly the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.The all spirit of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
