The utility model is characterized by the good effect of the filter gas, the smooth breath, not impacting the sight line and the safety and comfort.
Description
Technical field
The utility model is a kind of pneumatic filter, is a kind of nasal cavity type filter protection device specifically.
Background technology
The nasal cavity type protector that uses comprises gas filtration chamber, two nasal obstructions that connect with the gas filtration chamber respectively at present, and gas filtration has filter course on the chamber.There is following shortcoming in this dust cover: setting is not exhaled owing to not having, inlet valve, and the gas that the user breathes out is residual in the filter chamber, the filtering gas weak effect, and general gas filtration chamber is arranged on face, influences sight line, is unfavorable for operation.
Summary of the invention
The utility model provides a kind of filtering gas effective, breathe smooth and easy, do not influence sight line, the nose formula filter protection device of safety and comfort
The technical solution adopted in the utility model is: comprise that inside is provided with the gas filtration chamber of air filtering core, two nasal obstructions, two nasal obstructions link to each other with a nose breathing chamber, the middle part of nose breathing chamber is provided with outlet valve, the two ends of nose breathing chamber link to each other with conduit I by inlet valve respectively, conduit I links to each other with conduit II by connector, the other end of conduit II links to each other with the gas filtration chamber, and described connector is provided with elastic frenulum.Air filtering core is a folding type filter element, and replaceable, can also adopt a kind of in dustproof filter core, protection from fumes filter core, the gas defence filter core according to the environment needs that use.
Strengthened filtration to gas because the utility model is provided with two gas filtration chambers, filter core adopts collapsible, also is the area and the number of plies in order to increase filtering gas, and gas filtration is effective, after the gas filtration chamber is arranged on ear, does not influence sight line, is convenient to operation; Be provided with exhale, inlet valve, can make the gas noresidue of exhalation, ventilation effect is good, breathes smooth and easy.

The specific embodiment
The utility model comprises that inside is provided with the gas filtration chamber 4 of air filtering core, two nasal obstructions 1, two nasal obstructions 1 link with a nose breathing chamber 2 respectively, the middle part of nose breathing chamber 2 is provided with outlet valve 3, the two ends of nose breathing chamber 2 link to each other with conduit I8 by inlet valve 5 respectively, conduit I8 links to each other with conduit II7 by connector 9, and the other end of conduit II7 links to each other with gas filtration chamber 4, and described connector 9 is provided with elastic frenulum 6.Air filtering core of the present utility model is collapsible, and replaceable, can also adopt dustproof filter core, protection from fumes filter core or gas defence filter core according to the needs of environment for use.Soft materials such as rubber, plastics or silica gel can be adopted in nose breathing of the present utility model chamber 4, place nose preceding soft comfortable.On gas filtration chamber 4, can also be provided with and it can be hung over buckling on the cap.
During use, elastic frenulum 6 is hung on the ear, before nose breathing chamber 2 placed nose, two conduit I8 were distributed in cheek place, both sides respectively, will have a stuffy nose then 1 to aim at the nostril and insert, and two gas filtration chambers 4 are placed on position behind the ear by conduit II7 respectively.If the user has the outside that cap or the helmet can be hung on gas filtration chamber 4 cap or the helmet.Can also be provided with adjustable frenulum between two gas filtration chambers 4, make certain position after two gas filtration chambers 4 are fixed on brain.When nasal cavity was air-breathing, outlet valve 3 cut out, and inlet valve 5 is opened, and gas is filtered by gas filtration chamber 4 after conduit II7, I8, nose breathing chamber 2 enter nasal cavity and finish air-breathing; During breath, inlet valve 5 cuts out, and outlet valve 3 is opened, directly 2 discharges from the nose breathing chamber of the gas of exhalation.Also can be directly during breath from mouth, breathe out or mouthful, nose breathes out together, and is convenient, flexible.
It is effective to the utlity model has filtering gas, and ventilation effect is good, breathes smooth and easyly, does not affect sight line, The characteristics of safety and comfort.
Claims (2)
1, a kind of nasal cavity type filter protection device, comprise that inside is provided with the gas filtration chamber (4) of air filtering core, two nasal obstructions (1), it is characterized in that: two nasal obstructions (1) link with a nose breathing chamber (2), the middle part of nose breathing chamber (2) is provided with outlet valve (3), the two ends of nose breathing chamber (2) link to each other with conduit I (8) by inlet valve (5) respectively, conduit I (8) links to each other with conduit II (7) by connector (9), the other end of conduit II (7) links to each other with gas filtration chamber (4), and described connector (9) is provided with elastic frenulum (6).
