In the interlayer that once filters web, be provided with the filter pulp support.
Exhaust membrane is closed when air-breathing, and filtered fresh air backs down breathing film and enters nasal cavity from the suction hole of both sides; During expiration, breathing film is closed, and the gas of breathing out from nasal cavity backs down the expiration film and discharges from exhalation passages.Reach the gas that to suck with breathing out and separate, increase the oxygen content of gas, reduce the purpose that peculiar smell produces.
Also have " v " opening at the top of anti-dust respirator, anti-dust respirator edge and bridge of the nose external form are matched, make the air intake passage sealing effectiveness better.
The advantage of the utility model anti-dust respirator is in particular in:
1, inhales separately.The mixed gases that the oxygen that makes suction is not breathed out with carbon dioxide of breathing out and oral cavity can be not few because of the oxygen content that sucks, and causes dizziness, symptom such as weak, and this mouth mask can change above-mentioned symptom.
2, twice filtration.Filtering for the first time under the halfway situation and sticking to the online dust of outside filter pulp for a long time sucking for a long time with under breathing energetically, may enter the lung health risk, there has been secondary filter more thorough.
3, two air bleeding valves.Air bleeding valve links to each other, middle non-resistance, and the gas that is more conducive to breathe out is discharged rapidly, has reduced the stop chance, so sense of smell is still less.
4, the generation of spacer separates the gas of exhaling and inhaling.
5, non junctions in the middle of two ropes are up and down given the person's of wearing comfort, can regulate degree of tightness.
6, at the middle part of last bungee one parcel is arranged, there is polybag the lining, and oral area has sealing strip, like this when not wearing on bungee and dust cover all encase, can guarantee the clean of mouth mask like this and prevent bungee when work hook, hang other thing assurance safety.
