Description
Technical field
The utility model is related to personal safety protective device more particularly to masks.
Background technology
In recent years, problem of environmental pollution getting worse, the Yangtze River Delta and Pearl River Delta etc. are economically developed with the development of economy
There is the haze weather of low visibility often in the main cities in area, have seriously affected people's lives and health.The master of haze
It is that grain size is less than 2.5 μm of particulate matters to want pollutant.So-called PM2.5 refer in surrounding air aerodynamics equivalent diameter be less than etc.
In 2.5 μm of particulate matter, also known as fine particle.Research shows that：10 μm are less than for aerodynamic size, especially grain size is small
In particle be not only not easy to capture, but also can float, can be sucked in lung by people for a long time in an atmosphere, in addition can by alveolar into
Enter blood, human airway, angiocarpy and central nervous system are caused to seriously endanger.Early in 2013, the World Health Organization
By PM2.5 regard as can carcinogenic substance, lung cancer can be led to, and aggravate the diseases such as cardiovascular system.
According to investigations, people account for about 13% in outdoor residence time, and protective mask is as resisting extraneous germ, virus, thin
Particulate matter etc. invades the last line of defense of respiratory system, and increasingly important role is played to people's health. GB2626-
Protective mask is divided into two classes by 2006：Prevent non-oily particulate matter (KN classes) and grease proofness particulate matter (KP classes).It is, in general, that KN
Class protective mask can only filter non-oily particulate matter, and KP classes mask can not only filter oiliness particulate matter, can also filter non-
Oiliness particulate matter.With the raising of industrialization degree, oiliness particulate matter (such as glance coal, mist of oil, coke oven cigarette, diesel oil in air
Tail gas etc.) proportion it is also increasing, at this point, KN classes protective mask can not provide efficient rejection rate.
Modern medicine study shows：Incidence and the death of the concentration level and respiratory system, heart and lung diseases etc. of particulate matter
There are positive correlations for rate, especially to children, old man and easy infection crowd.The concentration of PM2.5 does not increase by 10 μ g/m3, thus draws
The chronic obstructive pulmonary disease risen increases by 3%, and the pneumonia death rate increases by 4%, and ischemic heart disease increases by 2%.Therefore, exploitation is efficient
The KP class protective masks that low-resistance, comfort are good, skin-friendly is excellent are extremely urgent.
One good protective mask should have following four condition：First, filter efficiency height；Second is that respiratory resistance is small；Third,
There is excellent adaptation with user's face；Fourth, user is comfortable on, no constriction will not cause unhappy, uncomfortable in chest.It is existing
Some protective masks are generally divided into flat and collapsible two major classes by shape, and mouth is adjusted by tether or adjusting elasticity length
It is elastic when cover is worn.Above-mentioned protective mask has the following defects：1, the adaptation of face and protective mask is ignored, it is different
Face type is multifarious, only adjusts protective mask and face tether or adjusting elasticity length or by way of adding pressure nose bar
Stickiness, when use, are easy to leak out because of mask and face, to make mask lose protective action.2, flat and collapsible anti-
Retaining cover is close to face, and effective filtration area is too small, when using Airflow through filtrate near mouth and nose, breathing can be caused to hinder
Power increases suddenly, to reduce the comfort of product.
Invention content
Have and face adaptation is excellent, effective filtration area is big, pro-skin the purpose of this utility model is to provide one kind
Property it is good and at the same time filtering oiliness and non-oily particulate matter PM2.5 protective masks.
Realizing the technical solution of above-mentioned purpose is：
A kind of pro-skin type PM2.5 protective masks, including：
It is domed, and along the symmetrical mask body in center；
Arc-shaped netted, edge is fixed with the mask body edge, the holder being used to support on the inside of the mask body；
Integrated cricoid sealing fabric is formed with mask body edge heat pressure adhesive；
Symmetrically it is bonded in two buckles at both ends on the outside of the mask body；And
Elastic band in the embedded buckle.
Preferably, the mask body includes the suction of outer layer PP (polypropylene) non-woven fabrics, internal layer PP non-woven fabrics and middle layer
Attached barrier layer；
Together with the outer layer PP non-woven fabrics, absorption barrier layer and the respective edge heat pressure adhesive of internal layer PP non-woven fabrics；
It is fixed on the outside of the mask body through the outer layer PP non-woven fabrics, absorption barrier layer and internal layer PP non-woven fabrics
Breather valve.
Preferably, the absorption barrier layer includes：
PP melt-blown nonwoven felts；And
It is close to the active carbon fiber felt and/or Static Spinning film of setting with the PP melt-blown nonwovens felt.
Preferably, the holder is plastic stent, and material is PE (polyethylene), PLA (polylactic acid), PBS (polybutadienes
Sour butanediol ester), one kind in PP (polypropylene) and PCL (polycaprolactone).
Preferably, it is equipped with nose clip on the inside of the holder.
Preferably, the sealing fabric is by knitted fabric and PTFE (polytetrafluoroethylene (PTFE)) films and/or PU (poly- ammonia containing spandex
Carbamate) film is combined, or is combined with PE films by the knitted fabric containing spandex.
Preferably, the sealing fabric is combined by the woven fabric containing spandex with PTFE film and/or PU films, or by containing
The woven fabric of spandex is combined with PE films.
Preferably, the width of the sealing fabric is 2.0-4.0cm.
Preferably, the shape of the buckle is goat's horn shape, and cylindrical protrusion, height of projection 1-3mm are arranged at bottom.
The utility model has the beneficial effects that：The utility model can be closely fixed at mouth and nose, will not because bowing, turn
Head, the actions such as walk about, jump loosen, and do not interfere with the sight of wearer.Meanwhile the characteristic with pro-skin softness,
Comfort is good when use.By being arch by the cavity design of protective mask, effective filtration area is increased, breathing resistance is reduced
Power, comfort enhancing, can filter oiliness and non-oily particulate matter simultaneously.When air-breathing, carbon dioxide in gas content is sucked<
1%, wearer is not in the malaise symptoms such as breathing sexual dysfunction.
