[0002] The cultivation process of anaerobic microorganisms is an operation of strictly controlling the oxygen environment, aiming to simulate an oxygen-free or low-oxygen environment. Anaerobic culture tanks are used in the anaerobic culture of microorganisms. The culture vessels are placed in the anaerobic culture tanks, and carbon dioxide gas is continuously injected into the anaerobic culture tanks to completely squeeze out the air in the anaerobic culture tanks, or squeeze out a part of it, thereby controlling the oxygen content ratio in the anaerobic culture tanks. In addition, the tank body is opened during the process of taking and placing the culture vessels, so the intrusion of outside air will also change the oxygen content ratio in the anaerobic culture tank. After taking and placing, carbon dioxide gas needs to be re-injected into the anaerobic culture tank. During the entire process of microbial cultivation, the oxygen content ratio in the anaerobic culture tank needs to be detected multiple times.

The inner plate frame 36 fixes the support ring tube 31.

[0040] The sampler 33 includes a C-shaped spring piece 37, a plate dividing frame 38, a wind tool 39, an arcuate rack 40, a branch shaft 41 and a return spring 42. The plate dividing frame 38 is fixed on the unit frame 28. The arcuate rack 40 slides through the plate hole opened on the plate dividing frame 38. One end of the arcuate rack 40 is fixed with the C-shaped spring piece 37. One end of the branch shaft 41 is meshingly connected with the arcuate rack 40 through a fixed gear. The other end of the branch shaft 41 is transmission-connected with the wind tool 39. A return spring 42 is fixedly sleeved on the branch shaft 41, and the outer end of the return spring 42 is fixed on the plate dividing frame 38.

[0041] The wind device 39 includes a T-plate frame 43, a funnel tube 44, a fan shaft 45, a second valve spring piece 46, a fan 47 and an L-shaped plate box 48. One end of the L-shaped plate box 48 is fixedly connected to the ring tube 31. The closed end cylinder on the funnel tube 44 passes through the other end shell of the L-shaped plate box 48.

[0042] The detection head 32 includes a third valve spring 49, an isolation shell 50, an oxygen sensor 51, a fourth valve spring 52 and a second neck tube 53. The isolation shell 50 includes a cylindrical box and a short tube connected to the bottom of the cylindrical box. A second neck tube 53 runs through the box body on one side of the isolation shell 50. A suspended oxygen sensor 51 is arranged in the middle of the isolation shell 50. A fourth valve spring 52 is fixed to the inner wall of the isolation shell 50, and one end of the fourth valve spring 52 that swings is covered at the port of the second neck tube 53. An exhaust port is provided at the top of the cylindrical box on the isolation shell 50, and the third valve spring 49 is covered above the exhaust port. One end of the third valve spring 49 is fixed to the isolation shell 50. The top of the hard folded tube 15 is slidably inserted into the short tube of the isolation shell 50 by setting a barrel shell, and an exhaust hole is provided on the side of the barrel. The second neck tube 53 is fixedly connected to the ring tube 31. Fig.14The oxygen sensor 51 is a prior art device. The oxygen sensor 51 is connected to the display 4 by means of wires. In addition, the display 4 is connected to the round base 3 by means of wires. Thus, an oxygen monitoring system is formed between the oxygen sensor 51, the round base 3 and the display 4. The oxygen sensor 51 detects the oxygen content ratio inside the tank 1, transmits the data to the control chip in the round base 3, and displays the analyzed data through the display 4.

[0043] The culture vessel 7 is filled with microorganisms and culture medium. Carbon dioxide, that is, oxygen-free air, is injected into the tank tube 1 through the square tube 26, thereby squeezing out part of the air in the anaerobic culture tank, affecting the change of the oxygen content ratio in the anaerobic culture tank. The oxygen content in the anaerobic culture tank is detected by the oxygen sensor 51. Specifically, air is sampled evenly around the top of the culture vessel 7. The wind device 39 absorbs the air in the local space and then injects it into the ring tube 31. The specific process is: the main shaft 10 rotates to drive the spring 19, and then drives the L-shaped lever 30 to move around. The L-shaped lever 30 moves the samplers 33 encountered one by one, specifically pushing the C-shaped spring 37. The C-shaped spring 37 drives the arc rack 40 during movement, and the arc rack 40 moves to drive the split shaft 41 rotates, and then drives the fan 47 to rotate through the fan shaft 45, and the ambient air outside the funnel tube 44 is sucked into the funnel tube 44, and then injected into the annular tube 31 through the L-shaped plate box 48. Finally, the C-shaped spring piece 37 stops after being intercepted by the dividing plate frame 38, and the L-shaped dial column 30 and the C-shaped spring piece 37 are staggered and separated, and the air previously injected into the annular tube 31 will be further squeezed into the isolation shell 50, and then impact and lift the third valve spring piece 49 and then be discharged. The oxygen sensor 51 detects the air flowing through the isolation shell 50, so that the local air in the anaerobic culture tank is detected, and a plurality of air collection points are evenly arranged around the top of the culture vessel 7, that is, the sampler 33, so that the air environment data on the top of the culture vessel 7 detected is more uniform and accurate.

[0044] After the oxygen sensor 51 is detected, the interior of the isolation shell 50 will be refilled with carbon dioxide air, so that the oxygen sensor 51 will not come into contact with oxygen. The components in the oxygen sensor 51 that react to oxygen will only react during detection, and will be in an inoperative state at other times. In this way, the service life of the oxygen sensor 51 is longer. When it is not working, carbon dioxide is needed to isolate and protect the components. The specific process of injecting carbon dioxide air is as follows: at the end of the orbiting movement of the L-shaped lever column 30, it will push the tilted arc column 34 encountered by the top, and the tilted arc column 34 will translate to drive the L-shaped control column 35, and the inclined column on the L-shaped control column 35 will translate to push the hard folding tube 15, and after the hard folding tube 15 rises, the barrel shell at the top of the hard folding tube 15 will be inserted into the cylindrical box of the isolation shell 50, thereby isolating The cylindrical box of the shell 50 is connected to the hard fold tube 15, and at the same time, the column cap shell at the bottom end of the hard fold tube 15 will rise to lift up the first valve spring piece 24, and then the bottom end of the hard fold tube 15 is connected to the inside of the ring cover body 22, and the air in the ring cover body 22 begins to leak out, that is, the carbon dioxide gas is injected into the isolation shell 50 through the hard fold tube 15. After the L-shaped shift column 30 is separated from the tilted arc column 34, the support for the rise of the hard fold tube 15 disappears, and then the first valve spring piece 24 is reset to cover the first neck tube 25 again, and the first valve spring piece 24 presses down the hard fold tube 15, the gas in the ring cover body 22 stops leaking, and the top of the hard fold tube 15 will also be drawn out from the cylindrical box of the isolation shell 50. At this time, the sealed space where the oxygen sensor 51 is located is full of carbon dioxide gas to isolate and protect the oxygen sensor 51.
