Abstract
The utility model discloses a kind of mask increasing self-filtering area, including filter layer, the filter layer is formed with fold, and fold forms the cavity for increasing filter layer forced area;Fold forming is fluted, is interconnected by groove between cavity.The technical solution of the utility model keeps appearance constant by way of increasing the filter area of mask inner filtration layer but not changing mask shape, reduces respiratory resistance, improves the comfort of mask, and mask inner face can be prevented contaminated.
Description
Technical field
The utility model belongs to machinery field, and in particular to a kind of mask increasing self-filtering area.
Background technology
Existing mask production method is multilayer material tiling superposition, and filter layer is clipped among other materials, is then carried out
Machine-shaping.The effective filtration area of interlayer of mask filter layer is restricted by mask shape area.So mask is wanted preferably thoroughly
Gas can only select expensive filtering layered material excessively.It cannot achieve in the case where not changing filtering layered material type, reduce
Respiratory resistance improves gas permeability.
Utility model content
The purpose of this utility model is to provide a kind of masks increasing self-filtering area.The technical side of the utility model
Case keeps appearance constant, reduction is exhaled by way of increasing the filter area of mask inner filtration layer but not changing mask shape
Suction drag improves the comfort of mask, and mask inner face can be prevented contaminated.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of mask increasing self-filtering area, the filter layer are formed with fold, fold formed increase filter layer by
The cavity of power area;It is fluted to face forming in fold, it is interconnected by groove between the interior cavity to face.
Further to improve, the periphery of the filter layer is formed with the flange for keeping mask leakproofness.
Further to improve, the fold is V-arrangement.
Further to improve, the fold is S-shaped.
It is further to improve, between the filter layer is wrapped in outside mask inner face and mask;The two of the mask inner face
Side, which is provided with, pastes fixed structure.
Further to improve, the fixed structure of pasting is velcro, and the side of mask inner face is fixed with the first velcro
The other side of hair side, mask inner face is fixed with Velcro hook side.
Further to improve, towards the face of people, described Velcro hook side one end is connected to the first velcro hair side
Face on mask inner face and backwards to people, the other end is free end.
It is further to improve, it is provided with the second velcro hair side below the Velcro hook side
Further to improve, the mask both sides are respectively fixed with lanyard.
Description of the drawings
The partition structural schematic diagram of Fig. 1 the utility model;
Fig. 2 the utility model Structure of cross section schematic diagrames.
Specific implementation mode
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment 1
In conjunction with Fig. 1, Fig. 2, a kind of mask of increase self-filtering area of the present embodiment, including filter layer 1, the filtering
Layer 1 is formed with fold 2, and fold 2 forms the cavity 3 for increasing by 1 forced area of filter layer;It is recessed to face forming fluted 4 in fold 2
Slot 4 is so that interior be interconnected between the cavity 3 in face.
The principles of the present invention are as follows:According to pressure P=pressure F/ area S, in the case where F is constant, increasing S can be with
In the numerical value for reducing P, in the case where penetration resistance F is constant, increase filter area S, it is possible to reduce the numerical value of pressure P.Therefore
Fold 2 increase air by filter area, to reduce pressure.If mutually isolated between the cavity 3 that fold 2 is formed
And the filter layer near only mouth and nose is caused to be used, then so that respiratory pressure or larger, and the filter layer near mouth and nose
It can be quickly invalidated, to reduce the service life of mask.Therefore in order to overcome disadvantages described above, the bending formation groove on fold 2
4, each cavity 3 is connected to, so that air can be flowed from entire mask towards mouth and nose breathing place so that entire filter layer is equal
It is used effectively, not only substantially reduces pressure, also greatly increase the service efficiency of mask.
The process that fold is formed is as follows:By giving a discount to filter layer, bending, sizing and etc., increase filter layer
Surface area but not repeatedly stacking.It is superimposed again with other materials, then is processed molding.
And then in mask shape not fold, under the premise of keeping beautiful, fold processing is carried out to mask inside, to improve mouth
The gas permeability of cover reduces respiratory resistance, improves comfort and widely applicable property.
In order to prevent since fold makes mask surrounding air-tightness decline, the periphery of filter layer 1, which is formed with, keeps mask close
The flange 10 of envelope property.Flange 10 can also use flexible gas impermeable material, such as rubber making.
Fold 2 can be as shown in Figure 1 V-arrangement, S-shaped that also can be as shown in Figure 2.
When not used, mask inner face 6 is contaminated, cannot be used so as to cause mask, filter layer 1 is wrapped in for mask in order to prevent
Between 5 outside mask inner face 6 and mask;The both sides of the mask inner face 6, which are provided with, pastes fixed structure.By mouth after not having in this way
Cover doubling is fixed by pasting fixed structure so that mask inner face 6 is folded to inside, dirty in mask inner face 6 to prevent
Dye.Groove 4 is in the side for closing on mask inner face 6.
It is preferred that it is velcro to paste fixed structure, specifically:The side of mask inner face 6 is fixed with the first velcro hair side 7,
The other side of mask inner face 6 is fixed with Velcro hook side 8.
It is preferred that face of the first velcro hair side 7 towards people, 8 one end of the Velcro hook side are connected on mask inner face 6
And backwards to the face of people, the other end is free end.So that the soft-surface at 8 back of Velcro hook side keeps face towards face
Comfort.
Usually cause face uncomfortable in use, Velcro hook side 8 turns in order to prevent, 8 lower section setting of Velcro hook side
There is the second velcro hair side 11, such mask in the open state, by the second velcro hair side 11 pasted by Velcro hook side 8,
To prevent its turnup.
Mask both sides are respectively fixed with lanyard 9.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
