There is certain gap between the front face of mouth and nose chamber, face is not adjacent to mouth and nose chamber front face, avoids facial skin discomfort；It can
The opening on the outside of filter chamber is arranged in dismounting filtering module, and inside forms content cavity, and filtered air is in content cavity
Buffering accommodating.It is equipped with air inlet between filter chamber and mouth and nose chamber, is equipped with intake valve at air inlet, leads between filter chamber and mouth and nose chamber
Intake valve unilaterally connected is crossed, by intake valve by the air inspiration filter chamber outside cover when nose, by filter chamber
Removable filtering module filtering, by intake valve inlet port nasal cavity after gas filtration；Removable filtering module can be from filter chamber
It removes, realizes the purpose of replacement filtering body.
A kind of above-mentioned protective mask, filter chamber are symmetricly set on mouth and nose chamber two sides, are respectively equipped with intake valve therebetween.Mouth and nose
It is unidirectional identical as it that the filter chamber of chamber two sides passes through intake valve respectively.
A kind of above-mentioned protective mask, mouth and nose chamber front face are equipped with air conducting slot.It inlet port nasal cavity and is exhaled outside cover
Gas out passes through air conducting slot water conservancy diversion respectively.
A kind of above-mentioned protective mask, air conducting slot are arranged in the middle part of mouth and nose chamber, are extending vertically into from nasal cavity with respect to position
The air outlet valve of lower section.The gas of nasal cavity exhalation makes the gas of sucking by air conducting slot air conducting slot water conservancy diversion to air outlet valve
Do not obscure with the gas of exhalation.
A kind of above-mentioned protective mask, intake valve, air outlet valve are symmetrically arranged at air conducting slot two sides.Nasal cavity exhalation
Gas air outlet valve is arrived by air conducting slot air conducting slot water conservancy diversion, obscure the gas sucked and the gas of exhalation not.
A kind of above-mentioned protective mask, mouth and nose chamber) in be placed with cotton to moisturizing.Cotton to moisturizing is arranged between air outlet valve, in mouth
Nasal cavity lower needle adsorbs the water mist and moisture of cold and hot exchange, realizes dried and clean in covering.
A kind of above-mentioned protective mask, removable filtering module include fore-stock, after-poppet and filtering body, and filtering body button is set
Between fore-stock and after-poppet.Fore-stock is installed on cover, and after-poppet is installed on fore-stock, when replacing filtering body, only
After-poppet need to be removed from fore-stock.
A kind of above-mentioned protective mask, intake valve are air-supply check-valves, and air outlet valve is outlet air check-valves.The valve plate of intake valve
It is arranged intracavitary in mouth and nose, the valve plate of air outlet valve is arranged outside mouth and nose chamber, and when nose, the valve plate of intake valve opened, air outlet valve
Valve plate close, by the air intake filter chamber outside cover, air is after filtering body filters from intake valve inlet port nasal cavity；It exhales
When, the valve plate of intake valve is closed, the valve plate of air outlet valve is opened, and the gas of exhalation is guided to air outlet valve by air conducting slot, so
Afterwards from air outlet valve outlet nasal cavity.
A kind of above-mentioned protective mask, the flexible glue cover trailing flank of mouth and nose chamber two sides are equipped with accommodation groove, are equipped with and inhale in accommodation groove
Attached cotton.The cover trailing flank of mouth and nose chamber two sides matches with face, and adsorption cotton is adjacent to face, realizes the purpose of oil suction, absorbing sweat.
A kind of above-mentioned protective mask, cover are flexible glue cover.Intake valve, air outlet valve, removable filtering module are arranged in cover
On body, cleaning can be removed from cover, mouth and nose chamber, filter chamber can also be cleaned, and since cover is flexible glue cover, not influence cover
With the sealed connection effect of intake valve, air outlet valve.
