Description
Technical field
The utility model relates to a kind of mouth mask, particularly relates to a kind of soft collapsible mouth mask.
Background technology
In recent years, since, the air pollution problems inherent of some key areas of China and the huge public health loss caused thereof cause to be paid close attention to widely.2013, " haze " became annual keyword.In the January of this year, 4 times haze process shrouds 30 provinces (district, city), and in Beijing, only having 5 days is not haze sky.Pollute 10 the most serious cities in the world and have 7 in China.On January 4th, 2014, national mitigation is done, the haze weather of health risk is included in natural the condition of a disaster in 2013 and circulated a notice of by Ministry of Civil Affairs first.In February, 2014, point out when chairman Xi Jinping investigates in Beijing: the top priority that reply haze pollutes, improves air quality is control PM2.5.
PM2.5 refers to that its equivalent diameter is equal to or less than the suspended particulate substance of 2.5 microns, strictly says that these suspended particulate substances comprise solid, liquid and solid-liquid mixes three kinds of forms.Suspended particulate substance (SuspendedParticulate Matter, SPM) be main atmosphere pollution type, suspended particulate substance is less than according to overall suspended pellet (Total Suspended Particles, TSP), particle diameter that particle diameter can be divided into particle diameter to be less than 100 microns the fine particle PM2.5 that the coarseparticulate (PM10) of 10 microns and particle diameter be less than 2.5 microns.Coarseparticulate and PM2.5 are easily breathed by humans and animals and enter a series of pathogenic risk of lung's generation, also known as pellet.Wherein, PM2.5 due to its PM2.5 particle diameter little, containing a large amount of poisonous and harmful substances and atmospheric residence time is long, fed distance is far away, to health and Atomspheric Environmental remarkable.Correlative study shows, air PM2.5 concentration increases significantly can increase human carcinogen and non-carcinogenic risk, causes the mortalities such as such as lung cancer to rise.Such as, PM2.5 atmospheric concentration often increases by 10 μ g/m
3, lung cancer mortality will be caused to increase by 8%, and LBW infant rate increases by 10%, and the heart and lung diseases death rate increases by 6%.Another research of Green Peace shows, the premature death that current PM2.5 concentration level is often only in Beijing, people up to ten thousand just can be caused in Shanghai, Guangzhou, city, four, Xi'an.According to the World Health Organization estimation, 2008 due to air pollution cause China 470,000 people's premature death; The research of the World Bank shows, the death that 2003-2006 causes due to air pollution and the loss that disease is brought to China, be equivalent to 1.16% ~ 5% of GDP then.The research report that WHO delivers in the recent period shows, Atmospheric Particulate Matter has been the fourth-largest factor causing East Asia human mortality.
There is PM2.5 and pollute and come into effect control more than ten years in evening compared with developed countries in China, the PM2.5 air quality standard that such as U.S. promulgates for 1997 does sth. in advance 15 years than China, this can show that from another aspect China's economic development enters the similar stage, mainly refers to here consume or consume the huge stage.Also show that control PM2.5 fine particle now pollutes and passes by control TSP total suspended matter, PM10 pellet and pollute different by what have in essence simultaneously, field very widely will be related to, to economic society, there is far-reaching influence.
Premier of the State Council Li Keqiang holds Executive Meeting of the State Council on February 12nd, 2014, studies and deploys and strengthens the air contaminant treatments such as haze further.Control atmosphere pollution being mentioned the height improved People's livelihood, is the significant task advancing Ecological Civilization Construction.Since last Sep, State Council issued " prevention and control of air pollution action plan " (ten, state), each department, all departments' prompt action, set the goal, build mechanism, supervise by force, obtains extensive concern and the approval of the whole society.Central authorities make a decision and common people's " share a common fate, struggle altogether ", firm " trouble of cardiopulmonary " of eliminating the people.But atmosphere pollution is long term accumulation to be formed, and must fully realize the severe situation that preventing and controlling face, accomplish fluently the assault of fortified positions of Air Pollution prevention and control, protract war.
When so severe air pollution, haze take place frequently, carry out the protection of individual respiratory health than indispensable.Mouth mask is direct, the most the most frequently used protection methods of common people.The characteristic that ordinary populace wears mouth mask mainly contains 3 points: one be seal, two are high efficiency filters, three is that respiratory resistance is little.Mouth mask, can be divided into air filtering type mask and Gas feeding mouth mask.Gas feeding mouth mask is by air compressor machine, compressed gas cylinder device etc., and the face delivering to people through pipe and face shield is breathed for people, more common in hospital.Great majority used in everyday are the former air filtering type masks, comprise common non-woven fabric mouth mask, cotton mouth mask, medical mask, macromolecular material mouth mask etc.For varying environment, suggestion is worn dissimilar mouth mask and is protected.Here is the haze service condition of several frequently seen mouth mask:
General cotton warming mouth mask: this mouth mask protective action is nearly unavailable or effect is very low, comprises various so-called anti-PM2.5 mouth mask, is exactly almost that this type has added a plug-in type filter disc.
Medical protective mask: when going to hospital or have Influenza epidemic situation to occur, suggestion is worn qualified " medical protective mask " and is effectively protected.In anti-virus, the requirement in epidemic disease occupational exposure staff protection level secondary of Disease Control and Prevention Center of China, mouth mask filter criteria will reach FFP2 or N95 standard.
Active carbon mask: merely add the subduction effect to some peculiar smell.In protection particle performance, carbon-bearing does not have differentiated, and the active carbon mask that can reduce peculiar smell does not increase the protection to particle.
Disposable non-woven lint face mask: this type of mouth mask low price, in fact anti-haze effect is with regard to the filtration of layer of non-woven fabric, and result is self-evident, basic effectively very difficult.Usual recommendation oneself obtained flu, wore when preventing saliva from disorderly flying cross-infection.Or star is in order to hoodwink people, locally on airport etc. also calculate a good selection for blocking.
Domestic " PM2.5 " green shield mouth mask: after opening packaging, is that a common winter warming mouth mask adds and sent five so-called PM2.5 filter discs, carries out mark publicity, the non-constant of sealing property after wearing with the strainability of filter disc in mouth mask as the performance of mouth mask.The face but if mouth mask can not be fitted, stop that outside air enters, so anti-haze ability is exactly an amusement.
Singapore totobobo mouth mask: advantage: new style, the design of replaceable filter disc, can free cutting size with applicable face.Shortcoming: the same with green shield, does not perform mouth mask degree of protection standard, only by Nelson laboratory report, is without restraint known as by means of this part of report the printed words surmounting N95, and reality barrier propterty performance in consumers' association's selective examination is general.The most important thing is price unexpectedly up to 188 yuan/, filter disc about 8.5 ~ 23.6 yuan/right.
WoodyKnows rhinobyon type invisible mask: this publicity says it is that moulding meets nasal cavity natural form, airtight and comfortable, do not get any information can protecting PM2.5, just for allergic rhinitis, pollinosis, dust dust storm, animal hair etc., there is certain effect.
After the comparative analysis testing research of at home and abroad numerous mouth mask, can find, mouth mask sealing property of the prior art is bad, and is inconvenient to carry, pack and transport.
