[0013] 1. The utility model is provided with a feeding pipe and a valve at the bottom of the material storage box and the detection agent storage box. By opening the valve at the bottom of the material storage box, the medicine liquid inside the material storage box is injected into the extraction cup through the feeding pipe. By observing the change of the medicine liquid scale on the scale above the material storage box, the purpose of quantitative feeding is achieved. After the addition of the medicine liquid is completed, the valve on the lower side of the detection agent storage box is opened to allow the internal detection agent to slide into the extraction cup through the feeding pipe, thereby realizing rapid extraction of the medicine liquid and improving operating efficiency. The setting of the sealing rod above the box cover helps to maintain the pressure balance inside and outside the material storage box, so that the medicine liquid can flow smoothly.

[0014] 2. The utility model is provided with a cup cover and a stirring blade on the extraction cup. The stirring blade is driven by a driving motor to stir the medicinal liquid and the detection agent, thereby increasing the contact area between the medicinal liquid and the detection agent, ensuring that the medicinal liquid and the detection agent are fully mixed and the reaction is more uniform, thereby accelerating the chemical reaction or dissolution process, ensuring the uniformity of the entire solution system, helping to improve the accuracy and repeatability of the detection, shortening the experimental time, and improving work efficiency. After the reaction is completed, the diversion port provided on the extraction cup facilitates the transfer of the internal liquid, helps control the speed and direction of the water flow, and reduces liquid splashing.

[0023] Shorten the experimental time and improve work efficiency; two fixing rings 9 are provided on the top of the support frame 1, and a storage box 10 and a detection agent storage box 16 are placed on the fixing rings 9 respectively. The storage box 10 is covered with a box cover 11, and a sealing plug rod 12 is inserted and fixed on the box cover 11. The front sides of the storage box 10 and the detection agent storage box 16 are provided with a scale 15, and a feeding pipe 13 is provided at the bottom. A valve 14 is provided on the feeding pipe 13. By opening the valve 14 below the storage box 10, the liquid medicine inside the storage box 10 is injected into the extraction cup 2 through the feeding pipe 13, and the purpose of quantitative discharging is achieved by checking the scale changes of the liquid medicine on the scale 15 above the storage box 10; a moving rod 18 is inserted on the box cover 11 above the detection agent storage box 16, and a pressure plate 17 is fixed on the side where the moving rod 18 is inserted into the detection agent storage box 16.

[0024] A rubber stopper that matches the inner wall of the extraction cup 2 is provided at the bottom of the cup cover 4.

Two sets of feed channels 8 are respectively opened on the left side and the right side of the top of the cup cover 4. The stirring blade 7 is inserted into the extraction cup 2, and the feed pipe 13 is inserted into the extraction cup 2 through the feed channel 8. The medicine liquid and the detection agent inside the storage box 10 and the detection agent storage box 16 are transported to the interior of the extraction cup 2 through the feed pipe 13 below. After the medicine liquid and the detection agent are placed, the drive motor 6 is started to drive the stirring blade 7 to rotate to ensure that the medicine liquid and the detection agent are fully mixed, the reaction is more uniform, the chemical reaction or dissolution process is accelerated, and the detection efficiency is improved.

[0027] Open the valve 14 at the bottom of the storage box 10 to allow the detection agent to slide into the extraction cup 2 through the feeding pipe 13. The purpose of quantitative feeding can be achieved by changing the scale of the liquid medicine on the scale 15. After the liquid medicine is added, open the valve 14 on the lower side of the detection agent storage box 16 to allow the detection agent inside to slide into the extraction cup 2 through the feeding pipe 13.
