The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
The empty oxygen mixer 100 of the embodiment of the present invention is described below with reference to Fig. 1-Fig. 2.
A kind of empty oxygen mixer 100 according to an embodiment of the present invention, as shown in Figure 2, comprising: shell 1, blower 2, check valve
3, proportioning valve 4, first flow sensor 142 and oxygen concentration sensor 143.
Wherein, mixed oxygen storehouse 13 is equipped in shell 1, air inputs storehouse 11, oxygen inputs storehouse 12, empty oxygen exports storehouse 14, air
Input storehouse 11 and oxygen input storehouse 12 are separately connected the air inlet in mixed oxygen storehouse 13, and empty oxygen output storehouse 14 connects the outlet in mixed oxygen storehouse 13
Mouthful, empty oxygen output storehouse 14 has empty oxygen delivery outlet 141.Empty oxygen delivery outlet 141 is used to export the mixing with certain oxygen concentration
Good empty oxygen gas mixture.Empty oxygen gas mixture herein refers to the gas of air, oxygen according to a certain percentage after mixing
Body.
Blower 2 is located at air input Cang11Chu, and blower 2 is used to that the air in air input storehouse 11 to be driven to flow towards oxygen storehouse 13 is mixed
It is dynamic.Blower 2 herein can be connected to the air input storehouse 11 of outside air and inside.
Check valve 3 be arranged in series in air input storehouse 11 and mixed oxygen storehouse 13 between with control air from air input storehouse 11 to
Mixed 13 one-way flow of oxygen storehouse.Check valve 3 can prevent gas from inputting adverse current in storehouse 11 from mixed oxygen storehouse 13 to air.
As shown in Figure 1, proportioning valve 4 (being not shown in Fig. 2) is located at oxygen input Cang12Chu, proportioning valve 4 is for adjusting oxygen
Input the air flow rate that oxygen in storehouse 12 flows to mixed oxygen storehouse 13.
First flow sensor 142 is arranged in series between mixed oxygen storehouse 13 and empty oxygen output storehouse 14 defeated into empty oxygen with detection
The flow of export 14.
Oxygen concentration sensor 143 is located at sky oxygen output Cang14Chu, and oxygen concentration sensor 143 is electrically connected with proportioning valve 4.
The setting of blower 2 is inputted Cang11Chu in air by the empty oxygen mixer 100 of the embodiment of the present invention, and the rotation of blower 2 will be empty
Aspiration enters in air input storehouse 11, provides required air-source for empty oxygen mixer 100, this air-source can be external sky
Gas.Blower 2 rotate when, within and around will form negative pressure cavity, make air be quickly drawn into air input storehouse 11 in.Wind
When machine 2 stalls, stop input air.
The setting of check valve 3 inputs between storehouse 11 and mixed oxygen storehouse 13 in air, and the air in air input storehouse 11 can pass through list
The air that can smoothly enter into mixed oxygen storehouse 13 to valve 3, and enter in mixed oxygen storehouse 13 will not reversely flow back towards in air input storehouse 11, that is, avoid oxygen
Gas enters air input storehouse 11.In addition, check valve 3 provides inceptive direction when entering mixed oxygen storehouse 13 for air.
By adjusting proportioning valve 4, oxygen then with certain air flow rate, forms certain positive pressure and is filled into oxygen input storehouse
In 12, progress into later from the air inlet that oxygen inputs between storehouse 12 and mixed oxygen storehouse 13 into mixed oxygen storehouse 13, oxygen at this time
With certain initial flow rate, oxygen can be mixed in mixed oxygen storehouse with air, can when control incorporation time is more abundant
Mix with air oxygen uniformly.Air with certain initial flow rate and with certain initial flow direction, to a certain extent plus
Preliminary in mixed oxygen storehouse 13 of fast air and oxygen mixes.
Enter the oxygen in mixed oxygen storehouse 13, also can because check valve 3 setting without enter air input storehouse 11 in,
It effectively prevents oxygen to be leaked in outside air, avoid keeps oxygen proportion inaccurate because of leakage, saves oxygen
The effect of air, oxygen mix is effectively guaranteed in input quantity.
First flow sensor 142 can carry out traffic monitoring to the empty oxygen gas mixture of mixing, to monitor empty oxygen mixer
100 working condition shows 100 stable working state of sky oxygen mixer when flow keeps stablizing, and mixes the gas in oxygen storehouse 13
Without leakage.First flow sensor 142 can also be aided with the atmospheric pressure state judged in empty oxygen output storehouse 14.
After oxygen concentration sensor 143 is electrically connected with proportioning valve 4, when oxygen concentration sensor 143 detects sky oxygen gas mixture
In oxygen concentration be not up to preset value, proportioning valve 4 can be fed back, make proportioning valve 4 adjust aperture and input oxygen gas
Flow is flowed, to regulate and control the ratio of empty oxygen mixing, until oxygen concentration sensor 143 reaches preset value, in this way, making the regulation of oxygen
More accurate, the concentration of controllable oxygen is continuously adjusted by 21% to 100%.
It is understood that the empty oxygen Mixed Design structure in compared with the prior art, empty oxygen mixer 100 of the invention
Required electrical part is relatively fewer.Air, oxygen mix are abundant, and oxygen is not easy to reveal, save the cost.Empty oxygen gas mixture outlet
Stablize, it can be achieved that oxygen concentration 21%~100% is continuously adjustable, the empty oxygen that can supply a variety of oxygen concentrations as needed mixes
