Abstract
The invention discloses a breathing mask suitable for high-pollution weather. The breathing mask comprises a mask body covered with knitted fabric. The mask comprises a filter element connecting hole, a lens hole, an exhaust hole and a hook. A filter element is connected with the filter element connecting hole. A lens is installed in the lens hole. An exhaust unit for exhausting internal air is installed in the exhaust hole. The hook protrudes backwards. The mask is put on the face of a user so as to protect the face against disoperation by toxic substances. The filter element is sequentially provided with a first adsorption part, a catalysis part and a second adsorption part in the flowing direction of the air. According to the breathing mask, the air can be purified to the state that PM2.5 is 0, and benzene, methylbenzene, dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acraldehyde in the air are removed to be smaller than 0.01 milligram per cubic meter in concentration when the PM2.5 of haze reaches more than 1,000, and meanwhile the skin and the eyes of a wearer are protected.
Description
Technical field
The present invention relates to technical field of air purification, be specifically related to a kind of breathing mask of applicable high pollution weather.
Background technology
Haze weather is a kind of atmosphere pollution state, haze is the general statement to suspended particulate substance content overproof various in air, and especially PM2.5 (equivalent aerodynamic diameter is less than or equal to the particle of 2.5 microns) is considered to " arch-criminal " that cause haze weather.Sulfur dioxide, nitrogen oxide and pellet are the main compositions of haze.
In early or mid November, 2015, the city being representative with Shenyang and other places, its haze PM2.5 index reaches surprising 1140, belongs to serious pollution.Under this kind of environment, pollutant not only injures the respiratory system of people, and the organs such as eyes also can be caused to produce burning sensation, the health of damage eyes.
Existing safeguard procedures, be generally adopt mouth mask, mouth mask divides the medical mask only possessing filtering function, and doped with the mouth mask of active carbon.This kind of mouth mask, only play filtering function, can not filter completely the fine particle in air, pernicious gas simultaneously in air, such as sulfur and nitrogen oxides, even the organic pollution such as toluene, formaldehyde, methacrylaldehyde, still enters the respiratory system of wearer, causes very big infringement to healthy by above-mentioned mouth mask.
Meanwhile, described protection, is only placed in nose and mouth, and for other organs of face, such as eyes, without any protective effect.Also have breathing mask on sale at present on the market, its design with reference to breathing mask simplifies.But this kind of breathing mask is heavier, is generally only suitable for protecting operator to use in extreme environments, wears in daily life, comfortableness is very large problem, and meanwhile, its aesthetics is also inadequate, is not suitable for wearing in daily life.
Summary of the invention
The object of the invention is to propose a kind of breathing mask being applicable to highly polluted weather; it adopts specific expiration and air suction structure; under the prerequisite realizing filtering function; catalysis can also be carried out to air; by the harmful substance in air; such as nitrogen oxide, oxycarbide, organic odor contamination such as benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde etc.; carry out decomposing, being oxidized or/and adsorb; bactericidal purifying is carried out to air; guarantee filtered air is clean, protects the healthy of operator.
An object of the present invention is also to provide a kind of breathing mask, while the respiratory system of protection wearer, can protect eyes and the skin of face of wearer.
For reaching this object, the present invention by the following technical solutions:
Be applicable to a breathing mask for highly polluted weather, comprise the mask bodies covered by knitted fabric, described face shield comprises: filter core connecting hole, and filter core is connected with described filter core connecting hole; Lens opening, lens are arranged in described lens opening; Steam vent, the exhaust unit for discharging inner air is installed to described steam vent; And hook, be set to rearward projection, described mask is worn on the face of user to protect face not by the infringement of noxious material, and described filter core, according to the flow direction of air, is successively provided with the first adsorption element, catalytic member and the second adsorption element.
Described first adsorption element is provided with fibrous filter layer, and described fibrous filter layer is superimposed with paper fiber thing filter course and ultra-fine fibre glass thing filter course.
Described catalytic member is provided with catalyst layer, and described catalyst comprises following component,
A) copper of 6%-20%, zirconium, vanadium and tungsten composite oxides, its mol ratio is 1:(0.5-2): (0.5-2): (0.5-2);
B) silver of 3%-8% and anatase titanium dioxide, the mol ratio of Ag and Ti is 2:5;
C) the SAPO-34 molecular sieve of surplus;
Described second adsorption element is provided with adsorption layer, and described adsorption layer is made up of the nano titanium oxide of active carbon and Ag-bearing, and its mixing quality such as, than being 5:1-2:1,4.5:1,4:1,3.5:1,3:1 etc.
Breathing mask of the present invention is placed in the mouth and nose of wearer, the air sucked enters the first adsorption element, in the first adsorption element, successively through the filtration of paper fiber layer and ultra-fine fibre glass layer, the particle in air and macromolecular substances are filtered.
Air after filtering enters catalytic member subsequently, and in catalytic member, the organic pollution in air, such as formaldehyde etc., catalyzed oxidation, becomes harmless or be easy to other organic matters of absorbing.
Air after catalysis, enters the second adsorption element.In air, the organic pollution of catalyzed oxidation is absorbed by active carbon, and is distributed in the silver in active carbon, kills virus to the microorganism in air, thus reduces the content of bacterium.Thus the protection achieved wearer's respiratory system.
The breathing mask of applicable high pollution weather of the present invention adopts the mask of knitted fabric covering, mask bodies adopts rubber, silica gel, flexible PVC, TPU or PU polyurethane, TPE or TPR elastomeric material, the material of described main body is soft so and possess elasticity, compare with the face of wearer and agree with, can not produce and wear space thus the generation causing the situations such as gas leakage.Described mask bodies adopts knitted fabric to cover, and can promote the comfort level of wearer on the one hand, can increase aesthetics on the other hand.
Face shield of the present invention possesses lens, and described lens the eyes of available protecting wearer can can't affect sight line.
Filter core of the present invention is according to the flow direction of air, successively be provided with the first adsorption element, catalytic member and the second adsorption element, filter core is by choosing specific components A and B component, this catalyst is made to produce cooperative effect, can, when haze PM2.5 reaches more than 1000, this breathing mask be still made significantly to drop to 0 to haze PM2.5 in air.Simultaneously, catalyst activity of the present invention is high, catalytic action can be played under room temperature, the organic matter degradations such as the formaldehyde in air, benzene are called carbon dioxide, and be higher valence state by harmful oxysulfide, nitrogen oxide catalytic oxidation, and then with charcoal absorption, various pollutant is reduced to ppm level.The removal of benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde reaches less than 0.01 milligram/cubic metre, significantly reduces the content of microorganisms in circulating air simultaneously.
