[0002] Due to their large surface area and outstanding catalytic ability, metal nanoparticles play a unique catalytic role in various fields. In the field of electrochemistry, metal nanoparticles can be used as common modification materials. They have attracted much attention because of their excellent catalytic effects, relatively simple preparation and modification methods, and wonderful synergistic cooperation with other materials. They are often used on the surface of the working electrode to directly contact the substance to be measured to accelerate the reaction speed, thereby improving the detection performance of electrochemical sensors.

[0003] Chinese Patent CN217561394U discloses a sensor for rapidly detecting nitrite in water environment. Through the cooperation of a liquid supply mechanism and a transparent test tube, this technical solution can automatically add NO2- solution into the transparent test tube as needed. At the same time, aeration is carried out into the mixed solution through the air holes, so that the solution is evenly mixed to form a test solution. Compared with manual measurement and stirring one by one, the efficiency is higher, thus making the detection efficiency higher.

[0004] During the use of this nitrite sensor device, the bottom end of the liquid delivery pipe extends into the transparent test tube to inject the NO2- solution into the water body. However, this nitrite sensor device does not have a lifting function, resulting in the liquid delivery pipe hindering the staff from loading and unloading the transparent test tube, which is not conducive to the use of nitrite detection.

A plurality of aeration holes 11 are opened at the bottom end of the surface of the aeration pipe 9. A flow meter 13 is arranged on the liquid injection pipe 12, and a valve 10 is arranged on the aeration pipe 9.

[0025] The injection pipe 12 injects the NO2- solution into the water in the inner cavity of the transparent test tube 8, and then aerates the water through the aeration pipe 9 and the aeration holes 11, so that the water and the NO2- solution are mixed.

[0026] The bottom end of the transparent test tube 8 is connected to a plug-in needle 17, and the top of the workbench 2 is provided with a plurality of plug-in liquid delivery seats 18 adapted to the plug-in needle 17. The plug-in liquid delivery seats 18 are prior art and will not be described in detail here.
