Below in conjunction with the drawings and specific embodiments, the invention will be further described:

The present invention is as shown in Fig. 1,2,3,4,5,6, and a kind of quantitatively breathing equipment, comprises apparatus for temporary storage 1, and apparatus for temporary storage one side lower part is by the interface access source of the gas of normally closed solenoid valve 3, and opposite side bottom connects respirator 14 by only inhaling valve 11.In the present embodiment, apparatus for temporary storage 1 comprises housing 9, housing 9 tops have passage 8, air bag 10 is housed in housing 9, same level position, bottom three faces of housing 9 have fixing hole, be fixed with respectively normally closed solenoid valve 3, aeration valve 2 and only inhale valve 11, in aeration valve 2, be provided with lower position switch 6, in aeration valve 2 upper shell 9, be connected with upper limit position switch 7, upper limit position switch slides up and down and is connected with housing, in normally closed solenoid valve 3 one sides of housing 9, normally opened relay 4 is installed, normally closed relay 5, normally closed solenoid valve 3 is by lower position switch 6, upper limit position switch 7, normally opened relay 4, the automatic control circuit control of normally closed relay 5 opens or closes gas and enters in air bag 10, automatic control circuit positive pole is parallel with respectively lower position switch 6 inlet wires, the normally-closed contact inlet wire of normally closed relay 5 and upper limit position switch 7 inlet wires, the line parallel that goes out of lower position switch 6 two normally opened contacts of normally opened relay 4 and the inlet wire of coil, the connecting inlet wire of normally closed relay 5 coils of the outlet of upper limit position switch 7, the normally-closed contact outlet of normally closed relay 5 is connected with a normally opened contact outlet of normally opened relay 4, another normally opened contact outlet of normally opened relay 4 is connected with the inlet wire of normally closed solenoid valve 3, the coil outlet of normally closed relay 5, the coil outlet of normally opened relay 4 and the outlet of normally closed solenoid valve 3 are parallel on circuit negative pole.In the present embodiment, only inhale valve 11 and comprise plug sleeve 21, plug sleeve 21 is hollow circular cylinders, piston boit 20 is housed in plug sleeve 21, piston boit 20 is also hollow circular cylinder, the upper and lower two ends of plug sleeve sidewall have gas off-take 24 and air intake duct 28 vertically, gas off-take 24 lower ends have plug sleeve gas outlet 25 to plug sleeve wall inner side, air intake duct 28 upper ends have plug sleeve air inlet 27 to plug sleeve wall inner side, plug sleeve 21 upper ends have air entry 22, between air entry 22 belows and piston boit 20, stage clip 23 is housed, plug sleeve 21 lower ends have decompression air flue 18, decompression air flue 18 extends upwardly to plug sleeve top in the middle of plug sleeve wall, then eight goes out to be opened on plug sleeve outer wall, piston boit 20 lower sides have stick harness air inlet 19, piston boit 20 top sidewalls on the lower side have stick harness gas outlet 26, in the time that stage clip 23 extends, on stick harness air inlet 19, between edge and 27 times edges of plug sleeve air inlet, there is the interval of 5mm, on stick harness gas outlet 26, between edge and edge, 25 times, plug sleeve gas outlet, also there is the interval of 5mm, when stage clip 23 is compressed to the most in short-term, corresponding perforation completely between stick harness air inlet 19 and plug sleeve air inlet 27, also corresponding perforation completely between stick harness gas outlet 26 and plug sleeve gas outlet 25.In the present embodiment, respirator 14 comprises cover body 13, is fixed with sealed colloid 15 in cover body, and cover body bottom is connected with suction nozzle 17 by outlet valve 12, and the upper and lower both sides of cover body are fixed with respectively fixing band 16.

Before use, first the interface of normally closed solenoid valve 3 and source of the gas are connected, again the automatic control circuit of normally closed solenoid valve 3 is switched on power, then mobile upper limit position switch 7 sets object gas use amount, finally with fixing band 16, respirator 14 is worn on head, cover body 13 covers face and nose, sealed colloid 15 is adjacent to skin of face, make to form airtight space between cover body 13 and people's face, when air-breathing, in confined space between cover body 13 and people's face, form negative pressure, by suction nozzle 17, negative pressure is put on and only inhaled on valve 11, make piston boit 20 compression press springs 23 of only inhaling valve 11 to suction nozzle 17 direction motions, the air of outside along relief passage 18 enter plug sleeve 21 with piston boit 20 because of in the mobile space forming, to subdue piston boit 20 negative pressure being formed of moving, in the time that piston boit 20 is moved beyond 5mm, stick harness air inlet 19 is communicated with plug sleeve air inlet 27, stick harness gas outlet 26 is communicated with plug sleeve gas outlet 25, gas in air bag 10 passes through plug sleeve air inlet 27 along air intake duct 28, stick harness air inlet 19 enters in the cavity of piston boit 20, via stick harness gas outlet 26, plug sleeve gas outlet 25 enters suction nozzle 17 along gas off-take 24, enter the cover body 13 of respirator 14 along suction nozzle 17, in the confined space forming between sealed colloid 15 and people's face, enter human body by mouth or snuffing, air bag 10 declines because losing gas, air is entered and in housing 9, is subdued because of air bag 10 the formed negative pressure that declines by passage 8, when air bag 10 be down on aeration valve 2 along time, air bag 10 no longer declines, continue air-breathing, the interior formation negative pressure of air bag 10, aeration valve 2 is opened, the air of outside enters in air bag 10 and once sucks to supply human body the tolerance needing, when air-breathing end, device point two parts are worked simultaneously, a part is that aeration valve 2 is closed and touches lower position switch 6, lower position switch 6 conductings, make the coil electricity of the normally opened relay 4 that lower position switch 6 controls, thereby make two normally opened contact conductings of normally opened relay 4, the normally closed solenoid valve 3 energising work of one of them contact series connection, open the passage between source of the gas and air bag 10, object gas enters in air bag 10, connect with the normally-closed contact of normally closed relay 5 and form latching circuit in another contact, in the time that lower position switch 6 disconnects, still give the coil electricity of normally opened relay 4, make normally closed solenoid valve 3 continuous firings, keep the inflation to air bag 10, in the time that air bag 10 reaches specified altitude assignment, touch upper limit position switch 7, upper limit position switch 7 conductings, make the coil electricity of the normally closed relay 5 that upper limit position switch 7 controls, thereby the normally-closed contact of normally closed relay 5 is disconnected, latching circuit disconnects, the coil losing electricity of normally opened relay 4, two normally opened contacts are opened, normally closed solenoid valve 3 quits work, passage between source of the gas and air bag 10 disconnects, air bag stops inflation, simultaneously, another part is only to inhale valve 11 because there is no the effect of negative pressure, promote the direction motion of lower piston post 20 to air bag 10 at the pressure of stage clip 23, decompression air flue 18 outside aerofluxus is to subdue piston boit 20 malleation being formed of moving, stick harness air inlet 19 staggers with plug sleeve air inlet 27, stagger with plug sleeve gas outlet 25 in stick harness gas outlet 26, gas off-take 24 disconnects with air intake duct 28, make the gas in air bag 10 can not enter suction nozzle 17, the user waste gas of can breathing out at any time, waste gas is thrown in air from outlet valve 12.

Normal person's inspiration capacity is once 500ml left and right, oxygen consuming amount in general curative is 30% left and right, oxygen content in pure air is 21%, by calculating the amount of oxygen that also needs 57ml, before using, upper limit position switch 7 is adjusted to the position of 57ml, when air-breathing, first suck the oxygen of 57ml, remaining tolerance is compensated automatically by breathing equipment from air, do not need artificial to have participated in just can sucking accurately 30% oxygen, the work process of whole breathing equipment is freely controlled by the breathing of user, simple, convenient, practical.
