Abstract

The utility model discloses a multifunctional filtering particle respirator, which is characterized in that a smokeproof filtering layer is provided in addition to a gauze layer; a nose clip is provided in the middle of upper part of the respirator to prevent side leak; a neck protector is equipped at lower part of the respirator to further improve side leak prevention performance; the filter layer can be placed on a protruding bracket; the bracket can be omitted, and a diamond-shape needle felt or a open-cell foam plastic layer can also be added in the smokeproof filtering layer to improve the ventilation performance and comfort of wearing. With almost no leak, light structure, comfortable wear and low production cost, the utility model can prevent anthrax, flu and SARS virus as well as lead fume, oil mist, natrium smoke, radon daughter, toxic chemical fog, etc. The respirator can achieve bacteria and virus particle prevention rate of 92%, dust prevention rate of 99%, total penetrating leaking coefficient of only 3-6%, respiration resistance of 2.0mmH#[2]O, dead space of approximately 100cm #+[3], lower field of vision hindrance of 4 degrees and weight of approximately 4g.

Description

A kind of multi-functional anti-particulate mouth mask

Technical field

The utility model relates to a kind of anti-particulate mouth mask, but but the multi-functional anti-particulate mouth mask of especially a kind of not only bacteriological protection, virus but also smoke and dust proof.

Background technology

The mouth mask of relevant anti-communicable disease is less both at home and abroad at present, and 16 layers of cotton cloth respirator are overweight, and the side leakage of mouth mask periphery is bigger, and the anti-particle diameter＜virom crosome of 1 μ m and big slightly anthracia bacterium particulate effect are relatively poor, and dustproof Smoke prevention effect also owes desirable; The efficient anti-dust respirator of minority can anti-virus, but sterilization, cleans difficulty, the complex structure heaviness, and inconvenience is worn, and costs an arm and a leg, is difficult to promote.

The utility model content

The purpose of this utility model is to provide that a kind of structure is light and handy, resistance is little, protection efficiency is high, cleans easily, and is cheap, but both anti-communicable diseases, the multi-functional anti-particulate mouth mask of the Smoke prevention of can preventing dust again.

The utility model comprises gauze layer, mouth mask bound edge, degree of tightness headband, it is characterized in that, also is provided with the Smoke prevention filter material layer, and the middle position, top is provided with the nose clip of anti-side leakage; The Smoke prevention filter material layer can place between the inside and outside two-layer gauze, and the internal layer gauze also can save, and perhaps available nonwoven replaces.The Smoke prevention filtrate is preferably selected modification lower resistance filtrate for use; Nose clip can select for use aluminium flake or plastic foil iron clad silk or other similar materials to make; Nose clip can place between two-layer gauze or gauze and the particulate filter.Gauze (not having anti-cloth) layer, particulate filter preferably place on the convex support, and support should or have the material of similar performance to make with flexible plastic.As without support, then should in internal layer gauze or nonwoven, fill up ventilative Nomex of last layer rhombus or open cell foamed plastic bar again, to improve permeability and comfortable wearing.Mouth mask the right and left also should be provided with the particulate filter washer, and the mouth mask bottom is preferably set up and following chin coated and its bound edge is installed with the chin that protects of the elastic cord that can lie in strength portion, with the anti-side leakage performance of further improvement.

The utility model is side leakage free almost; Structure is light and handy; Comfortable wearing; Cost is also low; Virom crosome efficient such as bacteriological protection, influenza and SARS can reach 92%, and dustproof efficient can reach 99%, and total penetrating leaking coefficient is 3-6% only, respiratory resistance 2.0mmH ₂O, the about 100cm of dead space ³, hinder the visual field, below 4 degree.Wear this kind mouth mask, can prevent virus such as anthracia bacterium, influenza, SARS and lead fume, mist of oil, sodium cigarette, radon daughter infringement.

The specific embodiment

Below in conjunction with accompanying drawing three embodiment of the present utility model are illustrated.

Embodiment 1

With reference to Fig. 1, Fig. 2, particulate filter 7 places in the double gauze 6, constitutes Smoke prevention and other particulates, aerosol, bacterium, virus layer, and particulate filter selects for use modification lower resistance Smoke prevention filtrate to make; The crown center position is provided with the nose clip of making of aluminium flake 1 between the double gauze 6; Two limits are provided with particulate filter catch 5 about mouth mask; The gauze particulate filter places soft moulding on the convex support 2, fastens the elastic cord 3 that passes bound edge 4, and mouth mask promptly becomes convex.

Embodiment 2

With reference to Fig. 3, Fig. 4, its structure is substantially the same manner as Example 1, only the lengthening of the size below the mouth mask is made it to become the half elliptic that can envelope down chin and protect chin 9, and set up one and be through the elastic cord 8 that protects chin 9 bound edges, elastic cord 8 two limits from about the mouth mask pass, and can tie up to neck, like this, the side leakage of mouth mask bottom can be more effectively prevented, particularly under the situation of speech, also side leakage can be do not produced.

Embodiment 3

With reference to Fig. 5, Fig. 6, particulate filter 7 wraps between outer gauze 6 and the internal layer nonwoven 11, internal layer nonwoven 11 is made of two nonwoven, the ventilative Nomex of rhombus places in the internal layer nonwoven 11, the crown center position is provided with the plastics cloth and coats the nose clip 1 that iron wire is made between outer gauze 6 and the internal layer nonwoven 11, mouth mask the right and left is sewed with bound edge 4, penetrates degree of tightness headband 3 in the bound edge 4, fastens elastic cord 3 and can make the mouth mask after wearing become convex.
