The six groups of test tanks are fixedly connected to one end face of the connecting pipe through a group of air inlet pipes. Valves are provided on the air inlet pipe and the connecting pipe. The other end of the connecting pipe is fixedly connected to the upper end face of the reaction tank, so that the gas generated inside the reaction tank can be selectively passed into one or more groups of test tanks through the valve. By placing chemical reagents inside the test tanks, the specific composition of the gas can be tested and the gas can be completely recovered. The six groups of test tanks are covered with sealed glass covers.

[0034] In this embodiment, six groups of test tanks 7 are symmetrically fixedly connected to the upper end surface of the fixing seat 8, and the upper end surfaces of the six groups of test tanks 7 are fixedly connected to a group of air inlet pipes 5. Different types of test reagents and absorption reagents are arranged inside the six groups of test tanks 7 to facilitate the detection and absorption treatment of toxic gases. The six groups of test tanks 7 are each fixedly connected to one end side surface of the connecting pipe 6 through a group of air inlet pipes 5. Valves are provided on the air inlet pipe 5 and the connecting pipe 6. The other end of the connecting pipe 6 is fixedly connected to the upper end surface of the reaction tank 3, which is convenient for controlling the gas to be tested inside different test tanks 7, thereby producing different phenomena, and the gas can also be absorbed at the same time.

[0035] Specifically, the sealed glass cover 9 covers the six groups of test tanks 7 inside. The test tanks 7 and the sealed glass cover 9 are both made of transparent glass, which makes it easy for students to observe the detection process and the phenomena generated by the gas inside the testing mechanism 1.

[0036] In this embodiment, the end of the rotating connecting column 12 facing away from the fixed disk 11 is rotatably connected to the upper end surface of the base 4. Six groups of chemical additives 10 are symmetrically arranged on the fixed disk 11. Six different chemical reaction reagents can be placed through the six groups of chemical additives 10.

[0037] Specifically, the flexible support base 17 is made of elastic material and is conical and recessed into the bottom of the medicine tube 14 . The medicine tube 14 is transparent on the outside and contains chemical reagents.

[0038] Furthermore, the piston rod 13 is slidably connected to the medicine tube 14 , and the end of the medicine adding tube 15 away from the piston rod 13 passes through the upper end surface of the sealing member 18 , and the medicine adding tube 15 is slidably connected to the sealing member 18 .

[0039] Furthermore, two groups of temporary storage tanks 16 are symmetrically opened on the side end surface of the dosing tube 15 , and the lowest points of the two groups of temporary storage tanks 16 are at different heights, so that the chemical reagents in the drug tube 14 can enter the temporary storage tanks 16 .

[0040] In this embodiment, the side end face of the protection tank 24 is transparent, and the observation baffle 22 is specifically a regular hexagonal hollow prism made by staggering three groups of transparent acrylic plates and three groups of balloon membranes. When the reaction inside the reaction tank 3 produces gas, the balloon membrane bulges outward, making it easier to determine the generation of gas.

[0041] Specifically, the size of the seal 18 is adapted to the sealing groove 20 , the diameter of the medicine inlet groove 21 is larger than the diameter of the dosing tube 15 , and the medicine inlet groove 21 is directly above the experimental cup 23 , so that the medicine enters the protective tank 24 through the dosing tube 15 and then flows into the experimental cup 23 .

[0042] Working principle: When conducting a chemical experiment, put the reagents commonly used in chemical experiments into the six groups of reagent additives 10, and put five groups of different gas detection reagents and one group of reaction gas product absorption reagents into the six groups of test tanks 7. Put the basic reactants into the experimental cup 23, and then select the appropriate reagent inside the reagent additive 10 according to the chemical reaction formula. Press the piston rod 13 to fill the temporary storage tank 16 with the reaction chemical reagent, and then press the dosing tube 15 and the temporary storage tank 16 into the medicine feed tank 21. The reagent will automatically fall into the experimental cup 23 for reaction. After the gas is generated, it will cause the balloon membrane in the observation baffle 22 to bulge outward, and then the generated gas will be passed into different test tanks 7 through the connecting pipe 6 and the air inlet pipe 5 to determine the chemical properties of the gas product. Finally, the gas generated by the reaction is absorbed by the absorption reagent inside the test tank 7.

[0043] In summary, the integrated device for preparing and testing toxic gases, first of all, the device is made of transparent materials and sealed on the outside through the reagent tube 14, the test tank 7, the sealed glass cover 9 and the protective tank 24, so that the chemical reaction process from the addition of the reagent to the end of the reaction can be clearly observed, and the gas generated by the reaction will be sent into the inspection mechanism 1 for further detection, which is more convenient for observing the chemical products.

[0044] Secondly, an observation baffle 22 is set inside the protective tank 24, wherein the observation baffle 22 is specifically a regular hexagonal hollow prism made by interlacing three groups of transparent acrylic plates and three groups of balloon membranes. An experimental cup 23 is also set inside the protective tank 24. The experimental cup 23 is framed inside by the observation baffle 22. When the reaction inside the experimental cup 23 produces gas, the air pressure inside the observation baffle 22 will increase, and the balloon membrane in the observation baffle 22 will bulge outward, making it easier for students to observe the generation of gas.

[0045] In addition, six groups of test tanks 7 are symmetrically arranged inside the testing mechanism 1, and the six groups of test tanks 7 are fixedly connected to one end side face of a group of air inlet pipes 5 and a connecting pipe 6. Valves are provided on the air inlet pipe 5 and the connecting pipe 6, and the other end of the connecting pipe 6 is fixedly connected to the upper end face of the reaction tank 3, so that the gas generated inside the reaction tank 3 can be selectively passed into one or more groups of test tanks 7 through the valve. By placing chemical reagents inside the test tanks 7, the specific composition of the gas can be tested and the gas can be completely recovered, and the sealing glass cover 9 covers the six groups of test tanks 7 inside. The test tanks 7 and the sealing glass cover 9 are both made of transparent glass, so that the entire testing process is visualized and safe and pollution-free, which is convenient for students to conduct independent chemical experimental exploration.

[0046] In addition, six groups of pharmaceutical additives 10 are evenly arranged on the upper end surface of the fixed disk 11, and the pharmaceutical adding mechanism 2 is rotatably connected to the upper end surface of the base 4 by rotating the connecting column 12, so that the six groups of pharmaceutical additives 10 rotate around the rotating connecting column 12, wherein one end of the piston rod 13 passes through the upper end surface of the pharmaceutical tube 14, and one end of the piston rod 13 passing through the pharmaceutical tube 14 is fixedly connected to the dosing tube 15, and the seal 18 is fixedly connected to the bottom of the pharmaceutical tube 14 through the flexible support bottom 17.

By adjusting the piston rod 13, the seal 18 can be pressed into the inside of the seal groove 20, and then the dosing tube 15 is inserted into the protective tank 24 through the drug inlet groove 21. At the same time, there are two groups of temporary storage grooves 16 symmetrically opened on the side end surface of the dosing tube 15, and the lowest points of the two groups of temporary storage grooves 16 are at different heights. The outside of the medicine tube 14 is transparent and filled with chemical reagents.
