Description
Technical field:
The utility model relates to a kind of mouth mask, more specifically refers to the multifunctional protection mouth masks such as a kind of collection waterproof and breathable, antistatic, anti-ultraviolet, anti-PM2.5, anti-mite, antibiotic, comfort health-care, good airproof performance.
Background technology:
Issue along with State Council's new " ambient air quality ", can enter lung particle (PM2.5) and more and more cause people's extensive concern.PM2.5 refers to that in atmosphere, diameter is less than or equal to the particle of 2.5 microns, also referred to as entering the lung particle.Its diameter be less than the people the hairline thickness 1/20.PM2.5 is mainly derived from the residue that discharges through burning in the processes such as daily generating, industrial production, motor vehicle exhaust emission, mostly contains the noxious materials such as heavy metal.Weather scientist and medical expert think, the haze weather that is caused by fine particle is even larger than sandstorm to the harm of health.The particle of particle diameter more than 10 microns, can be blocked in outside people's nose; The particle of particle diameter between 2.5 microns to 10 microns, can enter the upper respiratory tract, but part can excrete by sputum etc., also can be stopped by the fine hair of nasal cavity inside in addition, to the human health damage less; And particle diameter is at the fine particle below 2.5 microns, and diameter is equivalent to human hair's 1/20 size, is difficult for being blocked.Can directly enter bronchus after being inhaled into human body, disturb the gas exchange of lung, cause the disease that comprises the aspects such as asthma, bronchitis and cardiovascular disease.How to avoid sucking the problem that this tiny particle has become everybody to pay close attention to.
The materials such as common gauze, nonwoven can't stop PM2.5 at all, because their space all too is large.
In addition, physical characteristic from dust, dust is solid impurity, how irregular shape is, has water imbibition, a large amount of dusts are arranged in air, and when relative humidity acquires a certain degree, steam namely forms water droplet, so dust is easily moistening by water, and also easy adsorption moisture, add friction because of object in environment, electrical equipment etc. and produce static, cause the particle such as current airborne dust mostly with electric charge, at present general processing mode is by the mouth mask filtrate being done processing in the level, utilizes the electrostatic attraction deposition principle to improve filter effect.But the shortcoming of this kind method is to have increased the electret technological process, has extended the process time, has improved cost.
And airborne dust granules flies upward everywhere with many bacterial viruses and worm's ovum mostly, spreads disease, as some positive serious harm mankind's of respiratory tract infection virus such as influenza health.Influenza because the variation of its cause of disease is fast, spread speed is fast, the general susceptible of crowd, control the reasons such as difficulty is large worldwide being very popular easily occur.The SARS of 2003, believe that a lot of people remember clearly, and the H1N1 influenza virus is very popular in the world now, and infection population quantity is constantly increasing.The main pharmacology measure of flu-prevention is exactly vaccine inoculation, yet when facing a kind of new influenza virus and being very popular, utilize prior art to put into production in enormous quantities and take at least the time of 6 months from the isolated strain to the vaccine, therefore, the diffusion velocity that mouth mask is influenza virus in people reduce is during this period of time worn in trip, blocking-up is with viral dust granules to enter respiratory tract, takes one of self-protection first-selected articles for use used.
At present, the major product of protectiveness mouth mask comprises the N95 mouth mask on the market.The N95 mouth mask is used for protecting the workman to resist dust, therefore pay attention to airborne particulate is leached.But this type of mouth mask absorbs water mostly.Report according to the microbiologist, virus is the droplet transmission when by patient, speaking, sneezing and/or coughing, for example on mouth mask the time when the spittle arrives a surface through air, if the top layer of this mouth mask is hydrophilic will absorption by mouth mask, because capillary effect penetrates this mouth mask, simultaneously because nexine directly contacts skin, if mouth mask nexine material very easily absorbs water, it is wet that the nexine material easily becomes, and of long duration also can multiply bacterium; Mouth mask has just become viral collector like this, is also extremely dangerous.
Equally,, if Respirator structure design is unreasonable, can cause sealing poor, also give the chance that in atmosphere, dust and bacterial virus are invaded, both uncomfortable also health risk.Therefore, when the design mouth mask, the structure of mouth mask and the function of layers of material and selection have following some requirement:
Comfortable ventilating while 1, considering to wear, the mouth mask number of plies is too much unsuitable, is designed to three-decker, is respectively skin, filtering layer and internal layer;
2, consider the sealing property of mouth mask, the structural design of mouth mask will meet Chinese/Asian's shape of face;
3, by guaranteeing that the spittle can not be absorbed by mouth mask while arriving surface or the spittle can not penetrate/be spread in this mouth mask while arriving surface, cladding material should have the waterproof and breathable function;
4, for guaranteeing that dust granules electric charge when arriving surface is removed, cladding material should have anti-static function;
5, for intercepting and kill the germ in the spittle, cladding material should have antibacterial functions;
6, for guaranteeing that mouth mask has anti-PM2.5 function, filtering layer material gap is less than 2.5 microns;
7, but the filtering layer material should have respiratory and Moisture absorbing ﹠ quick drying property;
8, the filtering layer material generally all absorbs water, and therefore should have anti-acarid function;
9, for guaranteeing that moisture can only be passed to skin by internal layer, the moisture of outside can not enter internal layer, and inner layer material should be selected hydrophobic material and have better wicking wet effect thoroughly;
10, consider that internal layer directly contacts skin, and will intercept and kill outside bacterium, inner layer material should have health care and antibacterial functions concurrently, simultaneously certain comfortableness will be arranged;
Many researchs about anti-PM2.5 or anti-dust respirator are arranged at present, but large multipotency meets wherein or two above demands, as patent 200820047556.6-" gray haze and ozone-air protective mask " design five-layer structure, wherein filter course is nonwoven cloth material, and adopt relevant scavenging material to arrange fabric, mouth mask only has the function of anti-PM2.5 and purification, and selection is more; It is the filtering layer material that patent 201210061581.0-" preventing entering lung particle mouth mask " adopts fluorine plastic film or sponge electret, and mouth mask only has adsorption electrostatic and antibacterial effect; The three-decker that patent 201220026054.1-" a kind of three-dimensional mask that can effectively filter PM2.5 " adopts polypropylene spunbond or melt spraying non-woven fabrics to form is the filtering layer material, only the filtering layer material has anti-PM2.5 and antibiotic effect, patent 201210004904.2-" a kind of Novel material mask ": use a kind of Novel ultralong superfine fibre nonwoven cloth material to make, only lay particular emphasis on anti-PM2.5, function singleness.In the situation that gray haze is serious, brainstrust is also advised with the N95 or the N99 medical protective mask that are shaped, although the effect that stops bacterial virus, PM2.5 is arranged, but this mouth mask is hydrophilic mostly, larger on breathing impact, have the patient of breathing problem not wear, and the N95 level is close and shape mouth mask size is bigger than normal, is not suitable for the Chinese shape of face.In addition, domestic physical dimension to anti-PM2.5 or anti-dust respirator mostly is not high with facial stickiness attention degree, be designed to plane more, this mouth mask does not have the nose seal approach or seals tight not, the imported product of the close and type mouth mask of part use according to the design of westerner's shape of face arranged, though domestic have design or spinning but size also seldom has in conjunction with Chinese's shape of face and distributes and go to consider, do not cause and suck from bridge of the nose both sides through filtered air, protection effect reduces.
