Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
nullAs depicted in figs. 1 and 2，The utility model includes source of the gas assembly、Oxygen concentrator and oxygen supply assembly，Source of the gas assembly includes screw compressor 6、Cooling fan 7 and filter 3，Oxygen concentrator includes control unit 2、Molecular sieve bed I 1、Molecular sieve bed II 4 and the air accumulator 11 with structure of voltage regulation，Oxygen supply assembly includes oxygen mask、Ventilation channel 9、There is anti-suffocation valve structure and the oxygenregulator 8 of the autonomous adjustment structure of oxygen flow，Molecular sieve bed I 1 and molecular sieve bed II 4 are respectively arranged with program control device I and program control device II，The gas circuit output of screw compressor 6 is connected with the gas circuit input of filter 3，The blowing mouth of cooling fan 7 is towards screw compressor 6，The gas circuit output of filter 3 is connected with the gas circuit input of program control device I and program control device II simultaneously，Molecular sieve bed I 1 connects with air accumulator 11 with the gas circuit output of molecular sieve bed II 4 simultaneously，The gas circuit output of air accumulator 11 is connected with oxygenregulator 8 by ventilation channel 9，Oxygen mask is arranged on the gas circuit output of oxygenregulator 8，Screw compressor 6、Program control device I and program control device II all electrically connect with control unit 2.Above-mentioned program control device I and program control device II are the controller that can realize telecommunication, for the conventional equipment of prior art.
nullAirborne molecular sieve oxygen system described in the utility model，Source of the gas compresses the gas of backward air pipe line output HTHP through screw compressor 6，The gas of HTHP first passes through after cooling fan 7 carries out cooling process，Flow to filter 3 again and remove oil、The solid impurities such as dust and most aqueous water，Clean pressure-air after process flows to molecular sieve bed to carry out separating air-making oxygen，Two molecular sieve bed alternations in oxygen preparation，One absorption、Another desorption，So circulate oxygen processed，The work switching of molecular sieve bed，Program control device I and program control device II are provided with the magnetic valve 10 electrically connected with control unit 2，It is controlled by magnetic valve 10 and control unit 2，The oxygen that molecular sieve bed separation air is produced is transported to air accumulator 11，Air accumulator 11 communicates with oxygen mask，Air accumulator 11 has storage finished product gas and pressure stabilization function，Too low or reduce air supply pressure fluctuation in order to prevent occupant on machine from breathing the supply gas pressure of generation simultaneously.Being provided with check valve in gas circuit between air accumulator 11 and two molecular sieve beds, the outlet of check valve is internal with air accumulator 11 to be communicated, and when preventing molecular sieve bed work from switching by check valve, the finished product gas in air accumulator reversely flows into sifting bed.Air accumulator 11 communicates with two molecular sieve beds, is that certain surge volume space is played in two molecular sieve bed work switchings.
Oxygenregulator 8 and oxygen mask all have three, and all by ventilation channel 9 with air accumulator 11 even, three oxygen masks are separately positioned on the gas circuit output of three oxygenregulators 8 to three oxygenregulators 8.Air accumulator 11 is connected with three oxygenregulators 8, and oxygenregulator 8 has anti-suffocation valve structure and the autonomous adjustment structure of oxygen flow.
As shown in Figure 3, anti-suffocation valve structure includes anti-suffocation valve epicoele 81, anti-suffocation valve cavity of resorption 86 and atmosphere inlet pipe 85, anti-suffocation valve epicoele 81 communicates with finished product oxygen pipeline B, the valve 84 for turning on or block atmosphere inlet pipe 85 and finished product oxygen pipeline B it is provided with in anti-suffocation valve cavity of resorption 86, valve 84 is provided with vertical connecting rod, spring 83 it is cased with on connecting rod, the upper end of connecting rod is provided with film 82, the upper surface of film 82 communicates with anti-suffocation valve epicoele 81, and in Fig. 2 and Fig. 3, A mouth all connects oxygen mask.
Anti-suffocation function: when product inlet operating pressure is less than 50kPa, user of service can suck environmental gas by anti-suffocation valve.When being 60L/min by the flow of anti-suffocation valve, flow resistance is not more than 100mmH2O.Mainly reach this function by the oxygenregulator structure of molecular-sieve oxygen generator, after the finished product gas of oxygen concentrator arrives separately at anti-suffocation valve epicoele after entering oxygenregulator inside, when oxygen source pressure is at more than 50kPa, gas pressure effect makes valve 84 close, and user of service smokes oxygen concentrator finished product gas；When oxygen source insufficient pressure 50kPa, oxygen source pressure can not close anti-suffocation valve 84, and user of service can be supplemented by anti-suffocation valve and suck environmental gas, to avoid oxygen source hypotony or inspissator not aerogenesis to cause apneic events.
As shown in Figure 4, the autonomous adjustment structure of oxygen flow includes steam vent 88 that bellows extensible member 89 communicates with air, for turning on or block the rubber blanket 87 of finished product oxygen pipeline B and steam vent 88, and rubber blanket 87 is fixed on the upper end of bellows extensible member 89.
The autonomous regulatory function of oxygen flow: realize oxygen flow from main regulation by oxygenregulator 8 structure in molecular sieve oxygen system, make the oxygen pressure of oxygenregulator tend to a stability range.Oxygenregulator 8 is designed with bellows extensible member 89, thus air pressure change is converted to change in displacement, by the change of position, control the cross section of oxygen channel, thus realize flow-control.When ground or use environment ＜ 2000m, ambient pressure is relatively big, and the oxygen production capacity of oxygen system is strong, the axial compressive force that bellows is subject to is bigger, bellows shrinks, i.e. rubber blanket 87 in Fig. 4 separates with the sealing surface of housing, and unnecessary oxygen is discharged from steam vent 88.Along with height above sea level raises, ambient pressure reduces, and air is the thinnest, and the oxygen production capacity of oxygen system declines, and the axial compressive force that bellows is subject to reduces, and bellows extends, and reduces oxygen discharge, or makes rubber blanket 87 compress housing seal face, stops oxygen discharge.So that oxygenregulator tends to a stationary value at the oxygen supply pressure of different altitude height (0～7000 meter).
