Description
Technical field
It the utility model is related to mouth mask, anti-the PM2.5 mouth masks and its filter core of especially a kind of replaceable cartridge.
Background technology
Haze weather is increasingly becoming the principal element for influenceing China's most area air quality, and particulate matter is the big of haze
Gas pollutant.Wherein, the particulate matter of equivalent aerodynamic diameter≤2.5 μm, we term it PM2.5, because its particle diameter is small, ratio
Surface area is big, the poisonous and harmful substance being easy in enriched air, and can enter with the breathing of people in vivo, even into human body
Alveolar or blood circulation system, the diseases such as cardiovascular-respiratory system are directly resulted in, be to damage human body in urban atmospheric pollution thing to be good for
The most important arch-criminal of health.
At present, in the market has a many anti-PM2.5 mouth mask, and its technology is divided into two major classes more, and one kind is charcoal absorption, and one
Class is electrostatic capture.Itself it is also one of source of particulate because activated carbon can be carried compared with multiparticulates in itself, therefore as
The filtrate of anti-PM2.5 mouth masks can not be really achieved the purpose of prevention diameter≤2.5 μm particulate matter.Electrostatic capture technology can be by directly
Footpath≤2.5 μm particulate matter is adsorbed onto on filter membrane by electrostatic interaction makes it cannot be introduced into respiratory tract, but its drawback is no specific aim,
Also there is suction-operated to the particulate more than 2.5 μm, a large amount of particulate absorption reduce the service efficiency of filter membrane on filter membrane.Meanwhile
High efficiency PM2.5 mouth mask prices are higher, and it is larger frequently to change consumer's burden.How a kind of safety and sanitation, repeatable profit are manufactured
The mouth mask filtered for diameter≤2.5 μm particle, is that those skilled in the art wish solve the problems, such as.
Utility model content
Technical problem to be solved in the utility model be for above-mentioned the shortcomings of the prior art and one kind is provided can
Anti- the PM2.5 mouth masks and its filter core of filter core are changed, effectively realizes the purpose that barrier PM2.5 particles enter human body, filter core is easy to
Change, convenient environmental protection, improve the service life of mouth mask, it is economic, practical.
The utility model is to solve the problems, such as that used technical scheme set forth above is：
A kind of anti-PM2.5 mouth masks of replaceable cartridge, it includes mask body and is arranged at the ear of mask body both sides
Hang, be provided with filter core in the mask body, the edge of mask body is provided with slide fastener opening structure, for changing filter core；Institute
State filter cartridge construction from outside to inside successively by the first nonwoven layer, (i.e. PVC is micro- for the PVC microporous film layers coated on the first nonwoven layer
Pore membrane polyvinyl chloride microporous barrier), activated carbon non-woven layer of cloth and the second nonwoven layer stacking setting form.
By such scheme, the mask body includes and the nexine of skin contact, the top layer with contacting external air, filter core
It is installed in the centre on nexine and top layer.Preferably, the first nonwoven layer of the filter cartridge construction is close to the top layer of mask body, and
Nexine of two nonwoven layers close to mask body.
By such scheme, the marginal texture that nexine and the top layer of the mask body contact with each other is circumferentially disposed into closing knot
Structure, so as to form a mezzanine space that can install filter core.Preferably, the nexine of the mask body contacts with each other with top layer
Marginal texture be circumferentially stitched into enclosed construction.
By such scheme, the slide fastener is arranged on the top layer of mask body.
By such scheme, for the PVC micropores film thickness between 30~50 μm, 30 μm are optimal, and porosity is 85%~
99%, the pore size of micropore is 1~3 μm, can filter out the particulate matter that diameter is less than 2.5 μm.In filter cartridge construction, first layer
Non-woven fabrics mainly plays first layer filtration, and it is small that the PVC microporous barriers coated on first layer non-woven fabrics can filter out diameter
In 2.5 μm of particulate matter, and activated carbon nonwoven layer then using its strong suction-operated further adsorb fines thing with
And go to eliminate the unusual smell, second layer nonwoven layer further can cross air filtering.Preferably, each layer of the filter core passes through suture
It is fixed.
By such scheme, the material on the top layer of mask body selection terylene, acrylic fibers, polypropylene fibre, polyamide fibre etc. it is single or
The chemical fibre of mixing；The ventilative fabric of the pro-skins such as the preferred full-cotton fabric of nexine of the mask body.
Compared with prior art, the beneficial effects of the utility model are as follows：
The anti-PM2.5 mouth masks of replaceable cartridge provided by the utility model use the structure design of replaceable cartridge, convenient
Environmental protection, improve the service life of mouth mask；Filter core is laminated using multiple layers of filters, and PM2.5 filter effect is reached
99% or so, solve common gauze, non-woven fabrics gauze mask at present and plastic net cloth mouth mask gap is relatively excessive can not stop PM2.5
Particulate matter, the purpose that barrier PM2.5 particles enter human body is effectively realized, toxic gas in air can be adsorbed, go to eliminate the unusual smell, allowed
Air of people's breathing to high quality.
