[0002] In environmental testing experiments, different reagents usually need to be added to react with samples in order to detect the content of sample components. Currently, environmental testing is gradually adopting scientific instruments, which simplifies the tedious work of operators and improves testing efficiency. On this basis, operators basically only need to put in samples, prepare detection reagents, and monitor the amount of reagents used. Currently, there are few or no reagent placement boxes specially designed for scientific instrument testing on the market, or there is no real-time detection function for reagent volume. In environmental testing, a variety of reagents are usually required, and the reagents are usually highly corrosive. If there is no special reagent box to be placed, it is easy to cause safety accidents due to accidental contact or improper placement. At the same time, operators need to pay attention to the amount of reagents used to avoid affecting the progress / results of the experiment due to insufficient reagents.

[0003] Therefore, it is necessary to provide a monitoring device that can monitor the amount of reagent in real time and a reagent placement box containing the same, which can monitor the amount of reagent in the reagent bottle in real time. Utility Model Content

[0021] It is to be noted that the directions of "left", "right", "up", "down", "front", "back", "inside" and "outside" in the following schemes are all relative directions and are not listed here one by one.

[0022] A monitoring device that can monitor the amount of reagents in real time, reference Figure 2 , including a mounting block 1. First positioning openings 15 are provided at both ends of the mounting block 1. A cavity 2 is provided in the mounting block 1. A through opening 4 communicating with the cavity 2 is provided on the upper side of the mounting block 1. A silicone gasket 8 is provided on the inner bottom wall of the mounting block 1. A pressure sensor 3 is provided on the silicone gasket 8. The position of the pressure sensor 3 corresponds to the through opening 4. A guide shaft 5 is slidably provided on the through opening 4. A silicone pressing sheet 7 is provided at the lower end of the guide shaft 5. The silicone pressing sheet 7 abuts against the pressure sensor 3. A placement cover 6 is provided at the upper end of the guide shaft 5. The reagent bottle 18 is placed on the placement cover 6, and the pressure is transmitted to the pressure sensor 3 through the guide shaft 5 and the silicone pressing sheet 7. The specific reagent remaining amount in the reagent bottle 18 is converted according to the pressure obtained by the pressure sensor 3, thereby realizing real-time monitoring of the reagent bottle 18.

[0023] A reagent placement box that can monitor the amount of reagent in real time, referring to Figure 1 , including a shell 12 with a hollow interior. A plurality of reagent placement positions 13 are provided on the shell 12. A monitoring device is provided in the shell 12 and is located directly below the reagent placement position 13. A second positioning opening 15 is provided on the shell 12, which matches the position, quantity and size of the first positioning opening 14. The bolt passes through the first positioning opening 14 and the second positioning opening 15, so that the monitoring device is installed in the shell 12.

When a reagent bottle is removed, friction between the guide shaft 5, the storage cover 6, the reagent storage area 13, and the housing 12 prevents the pressure sensor 3 from returning to its original position. The push rods 16 extend to push the storage cover 6 upward, restoring the pressure sensor 3.
