Strange land breath method and device thereof

Technical field

The present invention relates to a kind of strange land breath method and device thereof.

Background technology

In the prior art, in workshop working environment around, air quality is poor, and there are a large amount of trickle grits, serious harm people's is healthy, in the face of these rugged environments, conventionally gas mask or mouth mask are put in the measure of taking exactly, gas mask or mouth mask can be isolated some toxic gases and grit to a certain extent, but poor effect, and unsmooth breath, difficulty when exhalation, air-flow mass rate of emission is slow, evacuation time is long, difficulty when suction, power that will be larger is air-breathing and the duration is long, go down for a long time, people just feel like a hen on a hot girdle.

Summary of the invention

The present invention aims to provide a kind of strange land breath method and device thereof, changes the operation principle of respirator in prior art, overcomes the defect of existing respirator, can breathe the fresh air in strange land in the contaminated air of place of working.

The invention provides a kind of strange land breath method, pure air be transported in contaminated air with appendix, do not mix with contaminated air, have an interface with contaminated air, form air bolus, breathe for people as place of working air,

S1: before breathing, appendix starts to input pure air, and air bolus molecular number increases, when interface area, air bolus volume all reach after the maximum of setting, the pure air of input is by blast pipe, and respiratory siphon enters in contaminated air from air bolus;

S2: when air-breathing, air-breathing by being connected to respiratory siphon in air bolus, air bolus molecular number tails off, if interface maintains static, the words of constancy of volume, air bolus air pressure must diminish, be less than after atmospheric pressure, in interface must bear, the difference of outer surface pressure is indeformable, do not change volume, contaminated air just can enter air bolus from air bolus blast pipe, and in fact, when the air of air bolus is inhaled into, stressed difference between interface outer surface and inner surface is greater than 0, forming distance between interfacial point shortens, forming interfacial point shortens to the distance of the respiratory siphon mouth of pipe, the volume of air bolus diminishes along with the tailing off of molecular number of air bolus, stressed difference between interface outer surface and inner surface equals 0, the volume of air bolus is not in variation, in this process, contaminated air can not enter in air bolus by blast pipe, move and occupy but promote interface the space that the part air bolus that is inhaled into nostril occupies before not sucking to the respiratory siphon mouth of pipe, in breathing process, contaminated air, interface and air bolus three flow to the respiratory siphon mouth of pipe with the sectional area queuing that is several times as much as respiratory siphon, until air bolus volume is 0, now interface arrives the respiratory siphon mouth of pipe,

S3: when expiration, exhale by the respiratory siphon being connected in air bolus, air bolus molecular number increases, when interface reaches after the maximum of setting, when air bolus volume reaches the maximum of setting, the gas of exhalation, the gas of input pipe input is discharged air bolus in time by blast pipe.

The present invention also provides a kind of device for above-mentioned strange land breath method, comprises air bag, respiratory siphon, appendix, gas outlet and five parts of blast pipe,

A. air handbag is drawn together skeleton and bag film, and the difference of air bag maximum volume and minimum volume has been not less than the poor of gas flow that aspiratory action sucks and input of same time gas flow;

B. respiratory siphon, appendix, blast pipe are fixed on skeleton and are connected with bag film;

C. be provided with gas outlet with the same source of the gas of appendix, regulate the gas transmission speed of appendix by the caliber size of the outlet of gas outlet;

D. the length of respiratory siphon is the shortest is 0, i.e. the direct breathe air in nostril group;

E. blast pipe is the pipeline of one-way flow air.

The strange land breath method and the device thereof that adopt the embodiment of the present invention to provide, good dustproof effect, serviceability is good, the gas transmission speed of appendix is controlled by the size of the exhaust diameter that regulates gas outlet, easy to use, and control the air pressure of air bolus inside by the harmomegathus of bag film, thereby reach simple to operate, lower-cost technique effect.
