[0022] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail.

[0023] Laboratory waste liquid collection device, refer to Figure 1 - Figure 6 The apparatus includes an experimental table 1, a cleaning water tank 2 installed on the top of the experimental table 1, a cavity 101 opened on the wider side of the outer surface of the experimental table 1, a slide groove 102 opened on the outer surface of the experimental table 1 and above the cavity 101, a slide rod 3 installed between the narrower side walls of the inner surface of the cavity 101 and close to the slide groove 102, a slider 4 installed on the outer surface of the slide rod 3, a support frame 5 installed on the outer side of the slider 4, a drain head 6 installed at the bottom of the support frame 5, a hose 7 installed at the top of the support frame 5, and three sets of bases 8 installed at equal intervals at the bottom of the cavity 101, each base 8 having a waste liquid tank 9 on its top.

[0024] Reference Figure 1 - Figure 4The outer ring surface of the slide rod 3 is slidably connected to the inside of the slider 4. A cylindrical block 10 is installed on the outer side of the slider 4 and inside the slide groove 102. A handle 11 is installed at the end of the cylindrical block 10 away from the slider 4. The cylindrical block 10 is driven to slide inside the slide groove 102 by the handle 11. The cylindrical block 10 drives the slider 4 to slide outside the slide rod 3, which in turn drives the support frame 5 to move. This causes the drain head 6 to move above different waste liquid tanks 9. An indicator 12 is installed at the bottom of the handle 11. When the handle 11 moves, the indicator 12 is driven to point to one of the waste liquid tanks 9, so that the staff can more intuitively know to discharge into the required waste liquid tank 9. The top end of the drain head 6 passes through the support frame 5 and is connected to the hose 7. The top end of the hose 7 is connected to the cleaning water tank 2. The waste liquid passes through the cleaning water tank 2, the hose 7, and the drain head 6 into the inside of the filter frame 21.

[0025] Reference Figure 3 A vertical plate 13 is installed on the top of the handle 11. A movable block 14 is installed on the outer side of the vertical plate 13. A movable rod 15 is installed at the end of the vertical plate 13 away from the movable block 14. A return spring 16 is installed on the outer ring surface of the movable rod 15. A limit plate 17 is installed on the outside of the movable rod 15 and close to the return spring 16. By pulling the movable block 14 outward, the movable block 14 synchronously drives the movable rod 15 and the limit plate 17 to move and compress the return spring 16. Three sets of circular plates 18 are equally spaced on the outside of the experimental table 1 and above the slide 102. Limit holes 1801 are opened on the outer side of each circular plate 18. After moving the handle 11 to the desired position of the waste liquid tank 9, and ensuring that the movable rod 15 can overlap with the limit hole 1801, the movable block 14 is released. The restriction of the return spring 16 is released, and the movable rod 15 is driven into the interior of the limit hole 1801, and the limit plate 17 and the circular plate 18 are in contact.

[0026] Reference Figure 2 and Figure 5 The bottom of the waste liquid tank 9 has symmetrically opened limit grooves 901 at both ends, and the top of the base 8 has symmetrically installed limit blocks 19 at both ends. The inner wall size of the limit groove 901 is adapted to the outer ring size of the limit block 19. When the waste liquid tank 9 is taken out from the inside of the cavity 101, the limit groove 901 at its bottom slides synchronously along the limit block 19, which makes it easy to install the waste liquid tank 9 inside the cavity 101.

[0027] Reference Figure 6The waste liquid tank 9 has baffles 20 symmetrically installed on its narrow inner side walls. A filter frame 21 is installed inside the waste liquid tank 9 and on top of the two baffles 20. A handle 22 is installed at the top of each of the narrow inner side walls of the filter frame 21. The filter frame 21 is designed to filter out particulate matter in the waste liquid, making it easy to collect the waste liquid. The two handles 22 also make it easy to remove the filter frame 21 from the inside of the waste liquid tank 9 for cleaning. A label holder 23 is installed on the narrow outer side of the waste liquid tank 9. The label holder 23 allows staff to place labels inside, making it easy for staff to clearly identify the type of waste liquid tank 9.

[0028] The implementation principle of the laboratory waste liquid collection device in this application embodiment is as follows: During the process of collecting waste liquid in the laboratory, firstly, by pulling the movable block 14 outward, the movable block 14 simultaneously drives the movable rod 15 and the limiting plate 17 to move and compress the return spring 16. At this time, the movable rod 15 moves away from the circular plate 18, and the handle 11 drives the cylindrical block 10 to slide inside the slide groove 102. The cylindrical block 10 drives the slider 4 to slide outside the slide rod 3, simultaneously driving the support frame 5 to move, thereby driving the drain head 6 to move above different waste liquid tanks 9. When the handle 11 moves, it simultaneously drives the indicator 12 to point to one of the waste liquid tanks 9, making it easier for staff to intuitively know where to discharge the waste liquid into the required waste liquid tank 9. After the handle 11 is moved to the position of the required waste liquid tank 9, and the movable rod 15 is aligned with the limiting hole 1801, the movable block 14 and the limiting spring 16 are released. The disengaged movable rod 15 is inserted into the limiting hole 1801, and the limiting plate 17 and the circular plate 18 are attached, thereby fixing the drain head 6 to the top of one of the waste liquid tanks 9 that need to be collected. Then, the waste liquid flows through the cleaning water tank 2, the hose 7, and the drain head 6 into the interior of the filter frame 21. The filter frame 21 is set to facilitate the filtration of particulate matter in the waste liquid, making it easy to collect the waste liquid. The filtered waste liquid flows into the interior of the waste liquid tank 9. The two handles 22 make it easy to remove the filter frame 21 from the interior of the waste liquid tank 9 for cleaning. When the waste liquid tank 9 is removed from the interior of the cavity 101, the limiting groove 901 at its bottom slides along the limiting block 19, making it easy to install the waste liquid tank 9 inside the cavity 101. The label holder 23 is set to make it easy for the staff to place the label inside, so that the staff can clearly know the type of waste liquid tank 9, making the operation more intuitive and convenient.
