Abstract
The utility model discloses a protective facial mask for solid particles. The protective facial mask is mainly composed of a filtering layer, a facial mask support and tying belts. The filtering layer is divided into three layers which include the outer cotton cloth layer, the electrostatic spinning fiber layer and the inner cotton cloth layer from outside to inside, the electrostatic spinning fiber layer is wrapped by the outer cotton cloth layer and the inner cotton cloth layer, the sizes of air holes of the filtering layer are slightly larger than the sizes of air holes of the facial mask support, the filtering layer is pasted on the inner surface of the facial mask support through adhesives, and the filtering layer covers the whole ventilation area accordingly. The facial mask support is manufactured in the mode that the face outline is obtained through the existing laser scanner technology, and a 3D printer and the rapid shaping technology are adopted in an assisted mode, so that uniqueness is achieved; the air holes are formed in the facial mask support, the filtering layer is placed in the air holes, and the air holes are main channels for gas exchange between the nares and the outside; the tying belts are made of cotton materials, and the cotton tying belts are pasted to the edge of the facial mask support through the adhesives. The protective facial mask solves the problem that gas is leaked from the two sides of the positions, corresponding to the nares, of the protective facial mask; contamination particles in the existing air can be effectively blocked by the electrostatic spinning fiber layer.
Description
Technical field
The utility model relates to a kind of articles for daily use, relates in particular to the mouth mask of deleterious particle in a kind of pedestrian's of preventing air amount, belongs to labour health protector technical field.
Background technology
Urban air-quality and health are closely bound up, and mouth mask, as a kind of daily protective articles, can effectively filter out harmful visible or sightless material.Along with air pollution problems inherent becomes increasingly conspicuous, the quality of mouth mask performance is also more and more important.Common air particles has grit, dust, sub-micron dust, soot, spray dust, drips, cigarette, chemical fumes, coal smoke etc.PM2.5 is the important indicator of observing and controlling air pollution degree, refers in particular to fine particle.Fine particle refers to that diameter in air is equal to or less than the particle of 2.5 μ m, can directly be sucked in human body bronchus, disturbs pulmonary gases exchange, causes the diseases such as asthma, bronchitis and cardiovascular disease.With mouth mask, stop that it is a kind of simple method that these air particles enter human body.The mouth mask of circulation roughly can be divided into air filtering type mask and Gas feeding mouth mask on the market, and wherein air filtering type mask has occupied larger market proportion.Air filtering type mask is because being used different filter materials, and the performance of mouth mask is also not quite similar.Air filtering type mask can be divided into anti-dust respirator, operation mouth mask and active carbon mask, wherein anti-dust respirator is mainly used in preventing dust, effective when stopping larger particulate, but its particle barriering effect that is less than 5 μ m for diameter is very limited, and antibacterial ability a little less than; Operation mouth mask is manufactured by three layers of nonwoven, is applicable to operating room environment, can intercept particulates more than diameter 4 μ m; Active carbon mask has added adsorbent---active carbon, the effective pernicious gas such as the benzene in absorbed air, formaldehyde, but cannot effectively intercept for PM2.5, in addition, active carbon itself is exactly a kind of particle, by wearer, is sucked also and can work the mischief to human body.
At present, the filtering holes of the air filtering type mask of circulation is generally all very thick on the market, can only intercept particle larger in air, cannot effectively filter fine particle, and protection effect there is no guarantee, and cotton cloth respirator is almost useless.In addition, mouth mask and people's face are not fitted, and cause mouth mask very large in the gas leakage of both sides, nostril, are tantamount to open up a shortcut to inhalable particles in air.
Summary of the invention
The above-mentioned defect existing in order to overcome prior art, the utility model provides a kind of can effectively take precautions against PM2.5, and can blocking diameter at the daily mouth mask of the solid particle of 0.4～0.8 μ m.
A kind of solid particle protective mask of the utility model, is mainly comprised of filter course, mouth mask support and frenulum.Wherein, filter course is divided into three layers, respectively outer cotton layer from outside to inside, electrospun fibers layer and interior cotton layer, outer cotton layer is exposed in air, embroidered personal like's pattern in the above, electrospun fibers layer adopts electrospun fibers to make, the diameter of this layer of electrospun fibers is 500～800nm, electrospun fibers is carried out to random support row, form fibre net structure, the physical methods such as employing is mechanical or hot sticky are reinforced the major part of making filter course, electrospun fibers layer can blocking diameter at the solid particle of 0.4～0.8 μ m, outer cotton layer and interior cotton layer are coated electrospun fibers layer, utilize needlework three layered sutures to be combined and to be cut into the shape of mouth mask support air-vent, the size of filter course is larger than the shaped slightly of mouth mask support air-vent, utilize adhesive that filter course is covered on mouth mask support inner surface, make filter course cover whole ventilation area, mouth mask support is to be obtained facial contour and be aided with 3D printer and rapid shaping technique is made by existing laser scanner technique, there is uniqueness, reach more than 90% with people's face laminating rate, in mouth mask support, open air-vent, be used for laying filter course, air-vent is nostril and extraneous main thoroughfare of carrying out gas exchange, frenulum adopts cotton frenulum, utilizes adhesive that cotton frenulum is covered on mouth mask bracket edge.
The beneficial effects of the utility model are: 3D printing function is produced with people's face laminating rate and reached more than 90% mouth mask support, have successfully solved the defect of both sides, mouth mask nostril gas leakage; Electrospun fibers layer can effectively stop existing airborne contamination particle; Mouth mask support is made by scanning people face, has uniqueness.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of solid particle protective mask of the utility model.
In figure, 1-filter course, 2-mouth mask support, 3-frenulum.
The specific embodiment
A kind of PM2.5 solid particle of the utility model protective mask, is mainly comprised of filter course 1, mouth mask support 2 and frenulum 3.Wherein, filter course 1 is divided into three layers, respectively outer cotton layer from outside to inside, electrospun fibers layer and interior cotton layer, outer cotton layer is exposed in air, embroidered personal like's pattern in the above, electrospun fibers layer adopts electrospun fibers to make, the diameter of this layer of electrospun fibers is 500～800nm, electrospun fibers is carried out to random support row, form fibre net structure, the physical methods such as employing is mechanical or hot sticky are reinforced the major part of making filter course 1, electrospun fibers layer can blocking diameter at the solid particle of 0.4～0.8 μ m, outer cotton layer and interior cotton layer are coated electrospun fibers layer, utilize needlework three layered sutures to be combined and to be cut into the shape of mouth mask support 2 air-vents, the size of filter course 1 is larger than the shaped slightly of mouth mask support 2 air-vents, utilize adhesive that filter course 1 is covered on mouth mask support 2 inner surfaces, make filter course 1 cover whole air-vent region, mouth mask support 2 is to be obtained facial contour and be aided with 3D printer and rapid shaping technique is made by existing laser scanner technique, reach more than 90% with people's face laminating rate, in mouth mask support 2, open air-vent, be used for laying filter course 1, air-vent is nostril and extraneous main thoroughfare of carrying out gas exchange, and mouth mask support 2 has uniqueness, frenulum 3 adopts cotton tether, utilizes adhesive that cotton frenulum 3 is covered on mouth mask support 2 edges.
