Abstract
The utility model provides a protective respirator, comprising a nose cup which is stitched with a medical gauze lamination, ties arranged at the four corners of the nose cup and a filtering layer made of filter materials are stitched between the interlayers of the nose cup, wherein the filtering layer comprises a rough filtering layer and a fine filtering layer. Eye protection glasses 5 are arranged stitched on the upper edge of the nose cup to protect the eyes of wears. The protective respirator of the utility model is provided with the fine filtering layer, the filter efficiency, therefore, reaches more than 99.8 percent and the protective respirator has high filtering performance which is more than 17 times of that of the common medical gauze respirator, with an oil and mist filtering efficiency of more than 95 percent and fine ventilation property.
Description
Technical field
The utility model relates to mouth mask, is specially a kind of protective mask with filtration efficiency.This protective mask is applicable to that general population and medical personnel wear, and is used to intercept airborne dust, virus and the harmful organism factor.
Background technology
The frenulum that mouth mask electricity oronasal mask and oronasal mask are four jiaos constitutes.Existing mouth mask comprises the mouth mask that latest national standards limits, and its oronasal mask all is by the folded system of hospital gauze, makes and form.The filter efficiency of mouth mask is by the number of plies decision of hospital gauze, and the few filter efficiency of the number of plies is poor, and the number of plies causes oronasal mask thick stupid more.
Summary of the invention
The utility model solves the contradictory problems that exists between the existing mask filtration efficiency and the gauze number of plies, and a kind of have new structure and the high mouth mask of filter efficiency are provided.
The utility model is to adopt following technical scheme to realize: a kind of protective mask, and comprise by the folded system of hospital gauze, make the frenulum of four jiaos of the oronasal mask that forms and oronasal mask, can be sewed with the filter course of making by filtering material at the hospital gauze interlayer of oronasal mask.The filter efficiency of the filter course that the special filtering material is made is far above the multilayer hospital gauze, therefore, the filter efficiency of mouth mask described in the utility model is far above having the mouth mask of being made by the multilayer hospital gauze now and having overcome many, the thick stupid defectives of the existing mouth mask gauze number of plies again.
The filter course of making between the hospital gauze interlayer of the oronasal mask of mouth mask described in the utility model is made of coarse filtration layer and filter bed of essence.Adopt the filter course of thick, smart two-layer formation not only can guarantee that mouth mask had high filter efficiency but also can satisfy the requirement of the required air flow resistance of mouth mask.At present, multiple known filtering material is arranged, can be used to make above-mentioned filter course.Can select the third human relations filter cloth (can be divided into models such as NR1, NR2, F1 again), nonwoven, the glass fiber filter paper (as 6902 models etc.) of superfine fibre for use by its filtration coefficient as filter bed of essence; The coarse filtration layer can be used normal air filter material (MD96K air filter material as is well known), asbestos cloth etc. earlier.
The filter efficiency of the filter bed of essence that protective mask described in the utility model is set up in it is up to more than 99.8%, therefore this protective mask has high strainability, its filtration result is more than 17 times of common hospital gauze mouth mask (18 layers), the mist of oil filter efficiency is more than 95%, and has air permeability and good.This protective mask has also overcome common hospital gauze mouth mask and has satisfied many, the thick stupid deficiencies of the number of plies under certain strainability situation.
Description of drawings
Fig. 1 shows figure for structure of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
The specific embodiment
A kind of protective mask comprises by the folded system of hospital gauze, makes the frenulum 2 of four jiaos of the oronasal mask 1 that forms and oronasal mask, is sewed with the filter course of being made by filtering material between the hospital gauze interlayer of oronasal mask.
The filter course of making between the hospital gauze interlayer of oronasal mask 1 is made of coarse filtration layer 3 and filter bed of essence 4.Coarse filtration layer 3 selects for use normal air filter material (MD96K) to make, and filter bed of essence 4 selects for use the third human relations filter cloth of NR2 model to make.
Top edge in oronasal mask is seamed with screening glass 5.Make this protective mask can also protect the personnel's of wearing eye.Screening glass 5 usefulness bag is along the cloth bound edge.
Dual-side symmetry in oronasal mask is sewed with goffering 6.When assurance was worn, human body face contacted with the closely connected of mouth mask, thereby further strengthened the strainability of this protective mask.30 millimeters of the gofferings of dual-side apart from left and right edge, about 10 millimeters of goffering width.Goffering requires symmetrically.
In the interlayer of oronasal mask middle and upper part, be seamed with soft foil metal 7.After mouth mask is worn, with hand push this soft foil metal make mouth mask easily and the human body nose fit tightly.
Claims (7)
1, a kind of protective mask comprises by the folded system of hospital gauze, makes the frenulum (2) of four jiaos of the oronasal mask (1) that forms and oronasal mask, it is characterized by: be sewed with the filter course made from filtering material between the hospital gauze interlayer of oronasal mask.
