Description
Technical field
It is to be related to a kind of haze protective mask more specifically the present invention relates to mouth mask technical field.
Background technology
Haze is the general statement to various suspended particulate substance content overproofs in air, especially PM2.5 (aerodynamics
Equivalent diameter is less than or equal to 2.5 microns of particulate matter) it is considered as " arch-criminal " for causing haze weather.With the evil of air quality
Change, thick weather phenomenon occurs increasing, endangering exacerbation, how to obstruct being drawn into for particulate matter and be concerned about the most for people's go off daily
The problem of.
Mouth mask has obtained the concern of more and more people and used as article the simplest in respiratory protection.At present, respectively
Plant haze-proof mask, PM2.5 mouth masks, fine particle mouth mask layer and go out not group, these mouth masks are largely by way of directly obstructing
To filter finely ground particles, or by way of charcoal absorption obstruct particulate matter, therefore, these mouth masks in structure
The filter layer to particulate matter with iris action is provided with, to reach the purpose of protection.But, these mouth masks after use,
Grain thing can be enriched with the filter layer of mouth mask, and the accumulation of long period can block the mesh of filtering layer machinery barrier, cause exhaling for people
Suction drag rises, while will also result in secondary pollution, in this case, mouth mask needs to be changed.
At present, haze-proof mask of the prior art does not have clear and definite useful life, or according to Kaifeng time or the when of use
Between carry out useful life regulation.But, if be not used behind Kaifeng, being changed to the time limit can cause to waste；And use and use
The restriction of time is also indefinite, because the respiratory rate of different crowd is different, even if the time for wearing mouth mask is identical, particulate matter
Enriching quantity may also be different, therefore the restriction not science of this useful life.
