Abstract
The invention discloses a bowl-shaped three-dimensional folding dustproof mask. The inner layer of the mask is a non-woven fabrics skeleton, and the outer layer is shell fabric, and filter cloth and grid cloth are arranged between the inner layer and the outer layer; the middle section of the grid cloth is a horizontal weld line, and a vertical weld line which is connected with the horizontal weld line extends downwards to the opening edge; the grid cloth can be folded along the horizontal weld line and the vertical weld line; the mask is stuck with silicon rubber on one surface which contacts with the bridge of the nose and the lower forehead of a human face; and an one-way expiratory valve is arranged on one side below the horizontal weld line. The invention has the advantages that the bowl-shaped three-dimensional folding dustproof mask can be folded, can keep original shape after being restored, and has small space usage and provides convenience for packaging and transporting, and a user can conveniently put the mask in the pocket.
Description
Technical field
The present invention relates to a kind of mouth mask, particularly a kind of bowl-shaped three-dimensional folding dustproof mask.
Background technology
Present existing solid type mouth mask must not push, must not bend, and it is big to take volume, has brought very big inconvenience to packed and transported.
Summary of the invention
Technical problem to be solved by this invention is will provide a kind of can fold, take the little bowl-shaped three-dimensional folding dustproof mask of volume.
In order to solve above technical problem; The invention provides a kind of bowl-shaped three-dimensional folding dustproof mask, the mouth mask nexine is the nonwoven skeleton, and skin is a face cloth; Between the layer of innner and outer filter cloth and grid cloth; There is a horizontal bonding wire in the grid cloth stage casing, is connected with this horizontal bonding wire to extend downward a mouthful limit a vertical bonding wire is arranged, and can fold with vertical bonding wire along horizontal bonding wire; The bridge of the nose of mouth mask and people's face contact-making surface is pasted with silicon rubber with following volume, and a side is provided with one-way breather valve below horizontal bonding wire.
Described nonwoven skeleton be low melt point PET process can moulding nonwoven; Grid cloth be polypropylene process can moulding nonwoven, grid cloth stereo shape has played supporting role; Face cloth is polypropylene filament face cloth.
Described one-way breather valve, this outlet valve is made up of base and loam cake, and base is that a basin moulds materials and parts, and a cylinder is protruded at the center at the bottom of the basin, and there is circular hole at the cylinder center, and the surrounding is a through hole at the bottom of the basin, and basin mouth inner peripheral is fluted; Loam cake has the groove of flange and basin mouth periphery chimeric to projecting inward around it, and there are several cross-coupled support bars at the middle part of loam cake; Supporting the loam cake periphery, is through hole between the cross support bar, and cross support bar center protrudes out a cylinder; This cylinder just in time injects in the center hole of center column at the bottom of the basin; One silica gel thin film centre drill, one aperture pierces into the cylinder of loam cake, just in time whole through holes at closed above middle part.
Said silica gel thin film diameter has at the bottom of silica gel thin film and the basin at interval less than the diameter of basin mouth.
Superior effect of the present invention is:
1) mouth mask of the present invention along horizontal bonding wire and vertical bonding wire, can carry out twice-folded, and restores the original shape of back maintenance;
2) after mouth mask of the present invention folded, it was little to take volume, to packed and transported convenience is provided, and the user can put into pocket conveniently and carry.

The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is done further to describe.
Like Fig. 1, Fig. 2 and shown in Figure 3; The invention provides a kind of bowl-shaped three-dimensional folding dustproof mask, the mouth mask nexine is a nonwoven skeleton 1, and skin is a face cloth 4; Between the layer of innner and outer filter cloth 2 and grid cloth 3; There is a horizontal bonding wire 5 in grid cloth 3 stage casings, are connected with this horizontal bonding wire 5 to extend downward a mouthful limit a vertical bonding wire 6 is arranged, and can fold with vertical bonding wire 6 along horizontal bonding wire 5; The bridge of the nose of mouth mask and people's face contact-making surface is pasted with silicon rubber with following volume, and a side is provided with one-way breather valve 7 below horizontal bonding wire 5.
Described nonwoven skeleton 1 be low melt point PET process can moulding nonwoven; Grid cloth 3 be polypropylene process can moulding nonwoven, grid cloth 3 stereo shapes have played supporting role; Face cloth 4 is polypropylene filament face cloth.
Like Fig. 4 and shown in Figure 5, described one-way breather valve 7, this outlet valve is made up of base 71 and loam cake 72; Base 71 is that a basin moulds materials and parts, and a cylinder 711 is protruded at the center at the bottom of the basin, and there is circular hole 712 at cylinder 711 centers; The surrounding is a through hole 713 at the bottom of the basin, and basin mouth inner peripheral is fluted; Loam cake 72 has the groove of flange and basin mouth periphery chimeric to projecting inward around it, and there are several cross-coupled support bars 721 at the middle part of loam cake 72; Supporting loam cake 72 peripheries, is through hole 722 between the cross support bar 721, and cross support bar 721 centers protrude out a cylinder 723; This cylinder 723 just in time injects in the center hole 712 of 72 center columns 711 at the bottom of the basin; One silica gel thin film, 73 centre drills, one aperture 731 pierces into the cylinder 723 of loam cake 72, just in time whole through holes 722 at closed above 72 middle parts.
Said silica gel thin film 73 diameters have at interval at the bottom of silica gel thin film 73 and the basin less than the diameter of basin mouth.
