[0018] S4: Prevent dust from entering the neutralizing solution.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention provides a microenvironment detection device for biological toxicology research. During the rotation of the double-threaded rod, a plurality of driving plates are driven to rotate. During the rotation, the driving plates contact the L-shaped transmission plate. The L-shaped transmission plate moves toward the detection box under the action of its inclined surface. At this time, the pressure relief spring is compressed and deformed. The L-shaped transmission plate drives the push plate to move. The push plate drives the pressure relief plate to move. After the pressure relief plate passes through the air inlet groove, the mixed gas in the detection box enters the pressure relief box. After the driving plate leaves the L-shaped transmission plate, the pressure relief plate pushes the mixed gas in the pressure relief box from the air pipe to the neutralization solution in the neutralization box under the action of the elastic force of the pressure relief spring, thereby maintaining a stable air pressure and avoiding the continuous input of air causing the air pressure in the detection box to increase, thereby affecting the accuracy of the experiment.

[0021] (2) The present invention provides a microenvironment detection device for biological toxicology research. After placing a sealed box in a designated slot in the detection box, the sealing plate is closed. When the sealing plate contacts the two trapezoidal plates, it moves away from the sealing plate. At this time, the limit spring is compressed and deformed. After the sealing plate is closed, the trapezoidal plate will drive the trapezoidal plate to reset under the elastic force of the limit spring. At this time, the back of the trapezoidal plate will be close to the front of the sealing plate to ensure the sealing of the detection box, thereby preventing the poisonous gas in the detection box from leaking out of the detection box and affecting the health of the staff. Then, the driving motor is started, and the driving motor drives the double-threaded rod to rotate. The double-threaded rod drives a plurality of fan blades to rotate. The fan blades generate a suction force. The suction force will suck the outside air into the detection box through the air intake L-shaped pipe and the hemispherical filter plate, thereby ensuring the normal supply of oxygen in the detection box, thereby preventing the organisms in the detection box from dying due to lack of oxygen and affecting the experimental results due to long-term experiments. The hemispherical filter plate can effectively prevent external dust and impurities from entering the detection box;

[0022] (3) The present invention provides a microenvironment detection device for biological toxicology research. During the rotation of the double-threaded rod, the two internal thread blocks are driven to approach each other, and the internal thread blocks drive the connecting plate to move. The connecting plate drives the T-shaped slide plate to descend. During the descent, the T-shaped slide plate contacts the limiting rectangular plate 1 and pushes the limiting rectangular plate 1 to descend. The limiting rectangular plate 1 drives the rectangular slide plate to descend. At this time, the closing spring is compressed and deformed. At this time, the rectangular slide plate descends and opens a plurality of ventilation slots. At this time, the poison volatilizes and emits the poison gas to conduct experiments. When the laboratory is finished, the T-shaped slide plate is separated from the limiting rectangular plate 1. Under the elastic force of the closing spring, the sealing box can be sealed again to prevent the leakage of the poison gas, thereby improving the flexibility of the device.

[0023] (4) The present invention provides a microenvironment detection device for biological toxicology research. The mixed gas input into the neutralization box contains poisonous gas. If the poisonous gas is alkaline, the neutralization solution is acidic. If the poisonous gas is acidic, the neutralization solution is alkaline. After the poisonous gas reacts with the solution, water and some harmless gases will be produced. As the gas in the neutralization box increases, the gas will enter the grooved cylinder through the holes on the grooved cylinder. The gas will push the T-shaped hollow circular plate to move away from the detection box. At this time, the sealing spring will be stretched and deformed. When the air outlet on the T-shaped hollow circular plate leaves the grooved cylinder, the gas will be discharged from the sealing spring. When the air pressure in the neutralization box is low, At the same time, the elastic force of the sealing spring will ensure the sealing of the grooved cylinder to prevent external dust and gas from entering the neutralization box and affecting the reaction between the neutralization solution and the poison gas. After a long period of experiment, the temperature sensor can be used to detect the change of the organism's body temperature, which is of great significance for studying the effect of poisons on the metabolism of organisms, because changes in metabolic rate often lead to fluctuations in body temperature. The heart rate sensor can be used to measure the heart rate of animals to understand whether the poison affects the function of the cardiovascular system. The respiratory sensor can also be used to monitor the breathing frequency and depth of the organism to reflect the effect of the poison on the respiratory system.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The gas will enter the grooved cylinder 601 through the holes on the grooved cylinder 601, and the gas will push the T-shaped hollow circular plate 602 to move away from the detection box 1. At this time, the sealing spring 603 is stretched and deformed. When the air outlet 604 on the T-shaped hollow circular plate 602 leaves the grooved cylinder 601, the gas will be discharged from the sealing spring 603. When the air pressure in the neutralization box 508 is low, the elastic force of the sealing spring 603 will ensure the sealing of the grooved cylinder 601, thereby preventing external dust and gas from entering the neutralization box 508 and affecting the reaction of the neutralization solution and the poisonous gas.

At this time, the limit spring 607 is compressed and deformed. After the sealing plate 609 is closed, the trapezoidal plate 608 will be driven to reset under the elastic force of the limit spring 607. At this time, the back of the trapezoidal plate 608 will be close to the front of the sealing plate 609 to ensure the sealing of the detection box 1, so as to prevent the poisonous gas in the detection box 1 from leaking from the detection box 1 and affecting the health of the staff.

The T-shaped slide plate 806 will contact the limiting rectangular plate 906 during the descent process and push the limiting rectangular plate 906 to descend, and the limiting rectangular plate 906 will drive the rectangular slide plate 904 to descend. At this time, the closing spring 908 will be compressed and deformed. At this time, the descent of the rectangular slide plate 904 will open several ventilation slots 905. The poison 902 will volatilize and emit poison gas for experiment. When the experiment is over, the T-shaped slide plate 806 will leave the limiting rectangular plate 906. Under the elastic force of the closing spring 908, the sealed box 901 can be sealed again to prevent the leakage of poison gas, thereby improving the flexibility of the device. The mixed gas input into the neutralization box 508 contains poison gas. If the poison gas is alkaline, the neutralization solution is acidic. If the poison gas is acidic, the neutralization solution is alkaline. After the poison gas reacts with the solution, water and some harmless gases will be produced. As the neutralization box 508 is closed, the neutralization solution will be filled with water and some harmless gases. 08, the gas will enter the grooved cylinder 601 through the holes on the grooved cylinder 601, and the gas will push the T-shaped hollow circular plate 602 to move away from the detection box 1. At this time, the sealing spring 603 is stretched and deformed. When the air outlet 604 on the T-shaped hollow circular plate 602 leaves the grooved cylinder 601, the gas will be discharged from the sealing spring 603. When the air pressure in the neutralization box 508 is low, the elastic force of the sealing spring 603 will ensure the sealing of the grooved cylinder 601, and prevent external dust and gas from entering the neutralization box 508 to affect the reaction between the neutralization solution and the poisonous gas. After a long period of experiment, the temperature sensor can be used to detect the change of the body temperature of the organism, which is of great significance for studying the effect of poisons on the metabolism of organisms, because changes in metabolic rate often lead to fluctuations in body temperature. The heart rate sensor can be used to measure the heart rate of animals to understand whether the poison affects the function of the cardiovascular system. The respiratory sensor can also be used to monitor the respiratory frequency and depth of the organism to reflect the effect of the poison on the respiratory system.
