Embodiment 1
A kind of protective face mask comprises cover body 1, also comprises the frame unit 2 that is arranged on the cover body 1, is provided with inlet valve 3 and outlet valve 4 on the frame unit 2, is provided with the applying mouth 5 of fitting with people's face on the cover body 1.
A kind of protective face mask also comprises for the nose pad spare 6 that is communicated with nostril and cover body 1.
Nose pad spare 6 comprises the first built-in nose pad 601 and the second built-in nose pad 602, the first built-in nose pad 601 and the second built-in nose pad 602 are both ends open and are hollow, the first built-in nose pad 601 1 ends are communicated with the nostril and the other end is communicated with cover body 1, the second built-in nose pad 602 1 ends are communicated with the nostril and the other end is communicated with cover body 1, the first built-in nose pad 601 and cover body 1 are for removably connecting, and the second built-in nose pad 602 and cover body 1 are for removably connecting.。
The mouth 5 of fitting is provided with Double-layer cushion.
Between the second housing 401 and the protective cover 406 for removably connecting, between described cover body 1 and the frame unit 2 for removably connecting.
Be provided with the silver infiltration adsorption layer for sterilization on the filter core 306.
Silver is a kind of Fungicidal substance of natural brute force, can kill the virus, bacterium and the microorganism that touch, and silver-colored corrosion resistance is high.The filter core that is provided with silver infiltration adsorption layer is capable of washing, and can not affect sterilization anti-microbial property and the filterability of filter core.
The first built-in nose pad 601 and the second built-in nose pad 602: by soft and have the material of opposing bacterium, virus and microorganism to make.The first-selection of material is other silica gel of medical grade.It is strong that material also needs to possess elasticity simultaneously, the characteristic of high temperature resistant and resist chemical.This built-in nose pad has solved the problem that there is Leakage Gas in most face shields.Even in the situation that wearer's aggravating activities, the leakage that also can not produce gas.This design makes face shield be fit to the shape of face of different shaped shape and size.The wearer sucks by the nose pad and breathes out.The nose pad inserted facial cushion and from facial cushion, take out all comparatively easy, the convenient cleaning.
Cover body 1: can and have the material of opposing bacterium, virus and microorganism to make by softness.The first-selection of material is other silica gel of medical grade.It is strong that material also needs to possess elasticity simultaneously, the characteristic of high temperature resistant and resist chemical.Face shield 1 can be real look, Transparent color or translucent.The particular design of Double-layer cushion has been guaranteed the sealing of junction between people's face and the face shield 1.
Frame unit 2: the material of frame unit 2 is hard, guarantees the good seal of being combined with soft facial cushion.The range of choice of the making material of frame unit 2 is wider.Any resist chemical, high temperature resistant and impact resistance, impact (being difficult for crashing or producing slight crack), anti-naked light, non-friable material can use.Frame unit 2 is look really, transparent or edematus.Frame unit 2 is provided with inlet valve and outlet valve.Again the first hole clipping 305 interior reciprocating motions of the first elastic chuck 304, when air-breathing, air pressure in the face shield is lower than atmospheric gas pressure, promote the first valve block 303 and the second valve block 403 toward the motion of people's face direction, thereby the first valve block 303 separates with the first housing 301 and the second valve block 403 and the second housing 401 gluing, sealings, and air enters in the face shield 1 by the filter core 306 that is arranged on inlet valve 3 outsides; When exhaling, air pressure in the face shield is greater than atmospheric gas pressure, promoting the first valve block 303 and the second valve block 403 moves away from people's face direction, thereby the first valve block 303 separates with the second housing 401 with the first housing 301 gluing, sealings and the second valve block 403, and air is discharged by the space between the second valve block 403 and the second housing 401.During expiration, the humid air of discharging in the body so that filter core 306 keeps dry, prolongs its service life without filter core 306.Pass in and out face shield 1 with exhaling from different passages owing to air-breathing simultaneously, so gas is smooth and easy in face shield 1 interior circulation, the resistance of breathing is little.
The selection of filter core can be different and different according to the purpose of using.The filtering element (cartridge) that preferred a kind of special silver particles operation was processed, its sterilizing rate is up to 99%.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
