Description

Self-priming nasal cavity filter protection device
Technical field
The utility model is a kind of pneumatic filter, is a kind of self-priming nasal cavity filter protection device specifically.
Background technology
At present the nasal cavity type filter that uses is made up of gas filtration chamber, two nasal obstructions connecting with the gas filtration chamber respectively, and gas filtration is indoor air filtering core.There is following shortcoming in this filter: setting is not exhaled owing to not having, inlet valve, and the gas that the user breathes out is residual in the filter chamber, and breathing has some setbacks, the filtering gas weak effect.
Summary of the invention
The utility model provides a kind of filtering gas effective, breathes nasal cavity filter protection devices smooth and easy, safety and comfort.
The technical solution adopted in the utility model is: comprise gas filtration chamber, connect with the gas filtration chamber respectively two nasal obstructions and air filtering core, this filter chamber of gas is a tubular, air filtering core is separately positioned on the two ends of gas filtration chamber interior, be provided with inlet valve two air filtering core inboards, outlet valve is arranged on the middle part of gas filtration chamber; The outside, two ends of gas filtration chamber is respectively arranged with frenulum; Air filtering core can adopt collapsible resistance dirt filter cloth; Two ends, gas filtration chamber can also be provided with capping with holes, and air filtering core is fixed on the inside of gas filtration chamber by capping.Air filtering core of the present utility model can also adopt dustproof filter core, protection from fumes filter core or gas defence filter core according to the needs of environment for use.
Because the utility model is provided with and exhales, inlet valve, the gas that makes exhalation basic noresidue so ventilation effect in cover body is good, breathe smooth and easy, air filtering core adopts collapsible resistance dirt filter cloth, it is little not only to take volume, and gently, can also increase the area and the number of plies of filtered air, improved the gas filtration effect.At two ends, gas filtration chamber capping with holes is set, is convenient to dismounting, renew cartridge more.

The specific embodiment
The technical solution adopted in the utility model is: comprise gas filtration chamber (2), two nasal obstructions (1) that connect with gas filtration chamber (2) respectively and air filtering core (4), gas filtration chamber (2) is a tubular, air filtering core (4) is separately positioned on inner two ends, gas filtration chamber (2), be provided with inlet valve (5) in two air filtering cores (4) inboard, outlet valve (3) is arranged on the middle part of gas filtration chamber (2); The outside, two ends of gas filtration chamber (2) is respectively arranged with frenulum (6), and frenulum (6) can be the rubber-like material; Air filtering core (4) is collapsible resistance dirt filter cloth; The two ends of gas filtration chamber (2) can also be provided with capping with holes, and air filtering core (4) is contained in the inside of gas filtration chamber (2) by capping, also can come air filtering core (4) is dismantled, changed by opening capping.
During use frenulum (6) is hung on the ear, before gas filtration chamber (2) placed nose, will have a stuffy nose simultaneously (1) was aimed at nasal cavity and is inserted.When nasal cavity was air-breathing, the inlet valve (5) that is arranged on air filtering core (4) both sides was opened, and outlet valve (3) cuts out, gas enters nasal cavity after air filtering core (4) filters, when exhaling, inlet valve (5) cuts out, outlet valve (5) is opened, and the gas of exhalation is directly breathed out from outlet valve (5).
The utlity model has simple in structure, smooth and easy, the gas filtration good effectiveness of breathing.
