[0025] See as Figure 1-4 As shown, this specific embodiment includes a workbench 1, a support plate 2, anti-slip pads 3, a reaction flask 10, a conduit 11, a regulating valve 12, and a first collection bottle 13. The workbench 1 is a cuboid structure with an open front side. Support plates 2 are welded to the four corners of the bottom wall of the workbench 1, and anti-slip pads 3 are glued to the bottom wall of the support plates 2 to prevent slipping and improve stability. An electrical control box 4 is welded to the right side wall of the workbench 1. The reaction flask 10 is set on the top left side wall of the workbench 1. A conduit 11 is installed through the top wall, and a regulating valve 12 is installed through the conduit 11. A filter cotton 22 is embedded and fixed in the conduit 11, and the filter cotton 22 is located to the right of the regulating valve 12 to facilitate gas filtration and prevent particles from entering the first collection bottle 13. A first collection bottle 13 is installed on the top wall of the workbench 1. The other end of the conduit 11 passes through the top wall of the first collection bottle 13 and extends into the first collection bottle 13, and the first collection bottle 13 is located to the right of the reaction bottle 10.

[0026] It also includes:

[0027] Pressure sensor 23 is glued to the inner top wall of collection bottle 13 and is electrically connected to its own battery.

[0028] The suction pump 15 is fixed to the top wall of the workbench 1 by bolts and brackets, and the suction pump 15 is located on the right side of the first collection bottle 13. The suction pump 15 is electrically connected to the electrical control box 4 by wires.

[0029] The air inlet pipe 14 is disposed through the input end of the suction pump 15, and the other end of the air inlet pipe 14 extends into the first collection bottle 13 after passing through the top wall of the first collection bottle 13.

[0030] The No. 1 air outlet pipe 16 is disposed through the output end of the suction pump 15.

[0031] There are two No. 2 collection bottles 18, and both of them are set on the top wall of the workbench 1.

[0032] The second vent pipe 17 is connected to the lower end of the first vent pipe 16. The left and right ends of the second vent pipe 17 pass through the top walls of the left and right side second collection bottles 18 and extend into the second collection bottles 18.

[0033] Two pressure sensors 24 are attached to the inner top wall of the second collection bottle 18 on the left and right sides, respectively. The pressure sensors 24 are electrically connected to their own batteries. This facilitates the collection of multiple gas samples at once, saving time and improving work efficiency.

[0034] A motor 5 is bolted to the inner top wall of the workbench 1. A rotating shaft 6 is fixed to the output end of the motor 5 via a coupling. A turntable 7 is fitted and fixed on the rotating shaft 6. A fixing rod 8 is welded to the left top wall of the turntable 7. The fixing rod 8 is movably inserted into the top wall of the workbench 1. An indicator plate 9 is welded to the top of the fixing rod 8. The indicator plate 9 is movably fitted onto the first collection bottle 13. The motor 5 is electrically connected to the electrical control box 4 via wires. This allows for easy switching of the display status of the indicator plate 9 after the first collection bottle 13 is filled, making it convenient for staff to observe.

[0035] An electric telescopic rod 19 is fixed to the inner top wall of the workbench 1 by bolts. A connecting plate 20 is fixed to the bottom end of the electric telescopic rod 19 by bolts. Insulation sleeves 21 are symmetrically glued to the top wall of the connecting plate 20. The insulation sleeves 21 are movably inserted into the top wall of the workbench 1 and are movably fitted onto the second collection bottle 18. The electric telescopic rod 19 is electrically connected to the control box 4 through wires to facilitate the insulation of the gas in the second collection bottle 18 and prevent liquefaction.

[0036] When using this invention, the reactants undergo a chemical reaction in the reaction bottle 10 to produce gas. First, the regulating valve 12 is opened, and the gas enters the conduit 11. After passing through the filter cotton 22 to filter the particles in the gas, the gas enters the first collection bottle 13, increasing the gas pressure. The first pressure sensor 23 detects the gas pressure. When the gas pressure in the first collection bottle 13 increases to the set value, the first pressure sensor 23 starts the motor 5. The motor 5 drives the rotating shaft 6 and the turntable 7 to rotate. The turntable 7 drives the fixed rod 8 to rotate, and the fixed rod 8 drives the indicator plate 9 to rotate until the indicator plate 9 is full, making it convenient for staff to observe. The first pressure sensor 23 then controls the suction pump 15 to start. The suction pump 15 draws the gas from the first collection bottle 13 through the air inlet pipe 14 and discharges it evenly into the second collection bottle 18 through the first air outlet pipe 16 and the second air outlet pipe 17. This allows for the collection of multiple gas samples at once, saving time and improving work efficiency.

[0037] After collection is completed, the electric telescopic rod 19 is opened. The electric telescopic rod 19 drives the connecting plate 20 to move upward, and the connecting plate 20 drives the insulation sleeve 21 to move upward. The insulation sleeve 21 moves and is placed on the second collection bottle 18 to keep the gas inside the second collection bottle 18 warm and prevent liquefaction.

[0038] The beneficial effects of this specific embodiment after adopting the above structure are as follows:

[0039] 1. The setup of the air inlet pipe 14, suction pump 15, first air outlet pipe 16, second air outlet pipe 17, second collection bottle 18, first pressure sensor 23 and second pressure sensor 24 facilitates the collection of multiple gas samples at one time, saving time and improving work efficiency.

[0040] 2. The anti-slip pad 3 prevents slipping and improves stability; the electric telescopic rod 19, connecting plate 20 and insulation sleeve 21 facilitate the insulation of the gas in the second collection bottle 18 to prevent liquefaction.

[0041] 3.
