Abstract
The utility model discloses a dust bag for a dust collector, at least comprising an outer filer layer located at outside and an inner filter layer located at inside, wherein the outer and inner filter layers are mutually separated, thus when the dust bag is opened, a space is formed between the outer and inner filter layers. The dust bag for dust collector is simple in structure and ensures that gaps are kept between the multilayer filter materials for letting air to flow through; therefore, whole blowing rate after collecting dust is enhanced and the dust absorbing force is kept without falling.
Description
Technical field
The utility model 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 utility model purpose is: provide a kind of simple in structure and improve the dirt bag that the dust catcher of air quantity is used.
The technical solution of the utility model 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 its China and foreign countries' 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 utility model is less than the volume of described outer filter course.
Distance between outer filter course described in the utility model and the inner filtration layer is greater than 1mm.
The utility model also comprise outside filter course between filter course and the inner filtration layer.
Outer described in the utility model, inner filtration layer is nonwoven or paper.
Filter course described in the utility model is the filtering material of elasticity and porous.
Filter course described in the utility model is the plastic plate with micropore.
The utility model advantage is:
The utility model is simple in structure, guarantees to have between the multiple filtration material space to allow 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 drawings and Examples the utility model is further described:
Fig. 1 is a cross-sectional schematic of the present utility model;
Fig. 2 is a schematic perspective view of the present utility model;
Fig. 3 is installed to cross-sectional schematic in the dust catcher for the utility model;
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 utility model provides the specific embodiment of the dirt bag that a kind of dust catcher uses, and it comprises and is positioned at the outside and allows the outer filter course 22 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 its China and foreign countries' filter course 22 and the inner filtration layer 26, distance between it is at least greater than 1mm, 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, enters space 202 very swimmingly, and enters into outer filter course 22 very swimmingly by this space 202, avoids existing inside and outside filter course to fit mutually 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.
Be understandable that the dirt bag also can include only two-layer, and filter course is positioned at the inboard, also can realize the utility model purpose.
As shown in Figure 3, dirt bag 20 of the present utility model 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 allow 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 utility model is simple in structure, guarantees to have between the multiple filtration material space to allow 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 utility model and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the spiritual essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
