Described screen pack be HEPA high efficiency particulate air and or activated charcoal strainer.HEPA (High efficiencyparticulate air Filter), the Chinese meaning is high efficiency particle air filter, reach the screen pack of HEPA standard, 99.7% is reached for the efficient of 0.1 micron and 0.3 micron, the feature of HEPA high efficiency particulate air is that air can pass through, but tiny particulate cannot pass through.It can reach more than 99.97% to the particle removal efficiency that diameter is more than 0.3 micron (1/200 of hair diameter), is the most effective filtering mediums of pollutant such as smog, dust and bacterium.Activated charcoal strainer has excellent aerodynamics performance, and bulk density is little, and specific area is large, adsorption efficiency is high, and air resistance coefficient is little.Can deodorizing under certain air quantity, eliminate the unusual smell, environment purification, has good clean-up effect.HEPA high efficiency particulate air and activated charcoal strainer can be used alone, and also can use simultaneously or use other composite filter net.
Adopt above structure, purifier 1 combines with filter mask 2 by the utility model, by the air extraction structure 131 in purifier 1, the gas in the external world is sucked in container cavity 13 by the first air inlet 111 on shell 11, after being purified by treatment facilities 132 pairs of gases, filter mask 2 is entered, for people's incoming call again by the second air inlet 121; Due to the setting of air extraction structure 131, gas for the external world provides the half-duplex channel of the only import but no export entering purifier 1, extraneous gas major part is purified by treatment facilities 132, not only also can remove other particles except PM2.5, improve gas cleaning efficiency, also breathing can be made smooth and easy simultaneously, there will not be the sensation of feeling suffocated.And the gas of breathing out, then discharged by filter mask 2.Therefore air inlet is different from the position of giving vent to anger, and breath can not be caused by the problem again sucked.In addition, due to compact of the present utility model, be easy to carry.And purifier 1 and filter mask 2 removably connect, filter mask 2 can regularly replace or clean, and increases the cleanliness factor of filter mask 2, and that avoids due to filter mask 2 is dirty, and causes the secondary pollution of gas.
In addition, the two ends of described filter mask 2 are respectively equipped with fixture.Described fixture is the fixed band removably connected with described filter mask 2, described fixed band comprise bandage and magic strap.Fixed band can be one, and the two ends of fixed band are connected with one end of filter mask respectively, when use, directly can be set to head; Fixed band also can be two, and every bar fixed band is connected with one end of filter mask respectively, during use, is connected by the free end of two or fixed band.
Fixture can increase other parts of mouth mask and the stationarity of head, wears conveniently, also avoids the landing of electronic gauze mask.
In order to can for need in the utility model power device electric energy is provided, described mouth mask comprises supply unit, described supply unit be built-in power 4 and or external power supply.When arranging separately built-in power or external power supply, built-in power 4 is convenient for carrying, and not by the impact in time and geographical position, but there is the defect of electricity deficiency, and external power supply can continued power, but there is the defect of not Portable belt; When built-in power 4 and external power supply are arranged simultaneously, can be complementary not enough.
Described built-in power 4 is installed in described container cavity 13; Described built-in power 4 is by switch control rule, and described switch 5 is fixed on described shell 11, and one end of described switch 5 is positioned at the inner side of described container cavity 13, and the other end of described switch 5 is positioned at the outside of described container cavity 13.Built-in power 4 is installed in container cavity 13, directly with human body or extraneous contact, safe attractive in appearance again; By the control of switch 5, can increase whether use selective, the position of switch 5, can handled easily.
Preferably, the quantity of described second air inlet 121 is multiple, and the corresponding described air extraction structure 131 of multiple described second air inlet 121 is circumferentially uniformly distributed.Quantity due to the second air inlet 121 is multiple, comparing quantity is one, can reduce the size of each second air inlet 121, and the gas entered in described container cavity 13 is uniformly distributed, too large gas shock can not be caused to face, thus cause the discomfort of face.
Preferably, the quantity of described gas outlet is two, is symmetrically set in the both sides described filter mask 2 being positioned at face; Each described gas outlet is equipped with check valve.The quantity of residing gas outlet is set to two, and be symmetrically set in the both sides described filter mask 2 being positioned at face, be position according to the nose of human body and arrange, making the gas of characteristics of contaminated respiratory droplets have the structure of discharge in the both sides of described filter mask 2, improving the speed that gas is discharged.And by the setting of check valve, can make the gas of exhalation can only one-way flow, namely can only outflow filter face shield 2, and the gas in the external world does not enter filter mask 2 by described gas outlet, therefore, it is possible to ensure the gas of human body incoming call, to greatest extent through the filtration for the treatment of facilities 132.
Preferably, described air extraction structure 131 is one or more the combination in fan, blower fan and aspiration pump.As long as extraneous gas can be made by air extraction structure 131, described container cavity 13 is entered from described first air inlet 111 of described shell 11, after described treatment facilities 132, enter described filter mask for people's incoming call by the second air inlet 121 of described base plate 12; Air extraction structure 131 is not limited to the use of fan, blower fan and aspiration pump.Fan is preferably aerofoil fan.Flow direction due to the gas of employing aerofoil fan is the axis of axial flow air extraction structure, therefore, it is possible to make to enter the gas in described container cavity, maximum is filtered by treatment facilities 132, improves the filter effect for the treatment of facilities 132.
Preferably, described treatment facilities 132 be screen pack and or clarifier.The effect of described treatment facilities 132, after gas to external world processes, can provide quality good gas for people breathes, by filter screen filtration, also purify by clarifier, filter and clarifier can also be used simultaneously.
Wherein said filter mask 2, for having the forming materials of filtering function, is preferably nonwoven cloth material shaping; Built-in power 4 can be dry cell or rechargeable lithium battary; It is shaping that shell 11 and base plate 12 can be plastic material, is that plasticity is good because the cost of plastic material is low, be convenient to shaping, in addition plastic material is relative to iron, stainless steel and other metal materials poor thermal conductivity, under the environment that temperature is lower or higher, user can not be made to produce sense of discomfort.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
