It receives.Collapsible easy storage, it is specious, but breathing space is smaller.
The hog snout button of above example can be replaced tri-glide.
As shown in figure 3, the mask for another embodiment, which is clamshell, and there is provided hog snouts equally on ear-hang band 7 to buckle
10, with the embodiment of Fig. 1, i.e. mask body includes the PP non-woven fabrics being sequentially stacked from the inside to the outside for the interlayer structure of mask body
The compound PP layers 103 of internal layer 101, PET hot winds layer of cloth 102, graphene, meltblown fabric layer 104 and PP non-woven fabrics outer layer 105, this five layers
It is linked into an integrated entity by multiple ultrasonic fusing points separately.
The region segmentation of face is placed in from mask body, mask body includes the nose bridge 4 being sequentially distributed from top to bottom, mouth
Nose 3 and chin portion 2, by eight between the nose bridge 4 and the snout 3 and the snout 3 and the chin portion 2
Font folding line 5 is kept apart.
The structure of this clamshell is simple, is an integral structure, and is easily worked.The mode of its folding storage is：According to clamshell
Left and right sides doubling, then along splayed folding line 5 by the first half and lower half doubling.
The mask is additionally provided with one-way breather valve 6, and as shown in Figures 4 and 5, one-way breather valve 6 includes flap 602,601 and of valve deck
Valve seat 603, valve deck 603 are rectangular, and one end of the flap 602 is fixed on the valve seat 603, and the other end is freely covered in
On the valve seat 603；The valve deck 601 is equipped with venthole for covering the flap 602；The free end of flap 602
605 edge is shaped form, to reduce dead angle, convenient for 602 smooth folding of flap.Fixing end 604 of the flap 602 on valve seat
Edge is linear, to increase fixed stability.
Wherein, valve deck may be designed as the other shapes such as circle, and flap 602 is using elastic materials such as silica gel.Fig. 3's is unidirectional
Outlet valve 6 is arranged on the left side of mask body, can also be positioned on the center line of mask body, is breathed out with quick discharge
Gas, reduce residence time of the carbon dioxide in mask, but consider that the center of mask after wearing is curved surface, one-way breather valve
6 use elastic material.
Ear-hang band set by the embodiment buckles the rope of adjustment length using hog snout, long according to the different adjustment of face
Degree increases comfort and leakproofness.To realize said function, it can also use and hog snout button is replaced with into tri-glide.
Outer edge at the bridge of the nose of the mask body is equipped with deformable press strip 9, the inner edge at the bridge of the nose of the mask body
Edge is equipped with polyurethane foam pad.
Certainly, in order to further increase comfort and leakproofness, can also poly- ammonia be all set in a circle of mask inward flange
Foam pad is replaced with silicagel pad, but the former gas permeability is more preferable by ester foam pad.
The mask of the embodiment is when actually promoting, and generally one-size-fits-all formula, can be in mask sheet in order to improve its adaptability
The edge setting bungee of body, can be automatically adjustable to by elastic in different facial contours in this way.
Fig. 6 is the mask of another embodiment, is equipped with equally on ear-hang band 7 and buckles 10 for the hog snout of adjustment length.And
And it is another foldable structure, mask body 1 includes the nose bridge 4, snout 3 and the chin portion 2 that are sequentially distributed from top to bottom,
The left and right sides close with ear of the nose bridge 4 with 3 overlapping suture of snout, it is described chin portion 2 and ear
The close left and right sides with 3 overlapping suture of snout.
At the left side of the mask body 1, the overlapping suture of the nose bridge 4 and the snout 3 with the chin
On the center line that the mask body 1 is coincided at the overlapping suture of portion 2 and the snout 3；On the right side of the mask body 1
Side, at the overlapping suture of the nose bridge 4 and the snout 3 at the overlapping suture of the chin portion 2 and the snout 3
On the center line for coinciding with the mask body 1.
The overlapping suture is that hot melt presses, and the outer edge at the bridge of the nose of the mask body 1 is equipped with deformable press strip
9, inward flange is equipped with foam pad 8.
Mask body 1 is designed to that upper and lower two parts to the folding mode of intermediate inner surface inner surface, subtract by the embodiment
The small contaminated probability of mask extends mask service life.It will be arranged on ear position at folding, i.e. mask body 1
At the center of left and right sides edge, the center for the adhesive force that this folding mode can be by mask body 1 at the bridge of the nose and chin is drawn
In ear, mask body 1 is avoided excessively to disperse in the adhesive force of face, so as to improve the tight ness rating of mask and face.It will be upper
Half part and lower half portion are overlapped on the center line of mask body 1, it is ensured that and inner surface is wrapped completely when mask folds,
It is not exposed to outer.
In addition, in order to expand the space in mask, it can also be horizontal between the nose bridge 4 of mask body 1 and snout 3
To setting pleated portions, equally, pleated portions are laterally set between the snout 3 of mask body 1 and chin portion 2.
Figure 3 above and Fig. 6 provide two kinds of folding masks, and the utility model can also use another collapsible：
Mask body is mutually transverse to be folded to be formed with multiple pleated portions.The main purpose of this foldable structure is to expand breathing space,
And the inner surface of non-protected mask.
Finally it should be noted that：The above various embodiments is only to illustrate the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, those of ordinary skill in the art should
Understand：It can still modify to the technical solution recorded in foregoing embodiments either to which part or whole
Technical characteristic carries out equivalent replacement；And these modifications or replacement, this practicality that it does not separate the essence of the corresponding technical solution are new
