[0026] Specifically, the pumping mechanism and the water adding mechanism both include a guide cover 17 internally rotatably connected to a guide rack 19, the sterile water pipe 14 and the pumping pipe 15 are respectively fixedly connected to the two guide covers 17, and the two guide covers 17 respectively connected to the sterile water pipe 14 and the pumping pipe 15 are respectively provided with a sterile water adding port 20 and a water drain port 21, the driving mechanism includes a driving motor 18, the driving motor 18 and the two guide covers 17 are fixedly installed on the carbon dioxide incubator 1 through a fixing plate 16, the output shaft of the driving motor 18 is fixedly connected to the two guide racks 19, and The two guide racks 19 have opposite guiding directions. The sterile water pipe 14 can be connected through the sterile water inlet 20, and the drive motor 18 can be started to drive the two guide racks 19 in the two guide covers 17 to rotate simultaneously. Then, the sterile water sucked up through the sterile water inlet 20 is sent into the upper water tank 3 through the sterile water pipe 14 through the guide rack 19 in the guide cover 17 connected to the sterile water pipe 14. At the same time, the dirty water in the lower water tank 2 is pumped out and discharged through the drain port 21 through the guide rack 19 in the guide cover 17 connected to the water suction pipe 15.

[0027] Specifically, both sides of the sealing plate 6 are slidably matched with guide rails 8, and the two guide rails 8 are fixedly connected to the upper water tank 3. The two guide rails 8 facilitate guiding the sealing plate 6.

[0028] Specifically, the push-pull mechanism includes a pull rod 11 that is slidably matched with the guide seal of the carbon dioxide incubator 1. One end of the pull rod 11 that extends into the carbon dioxide incubator 1 is fixedly connected to the sealing plate 6 through a fixed block 10.

When the pumping and filling are completed, the driving mechanism is closed, and then the sealing plate 6 is pushed and pulled by the push-pull mechanism, so that the multiple grooves 7 on the sealing plate 6 are connected with the multiple leakage holes 4, and then the sterile water in the upper water tank 3 falls into the lower water tank 2. When pumping is needed again, the sealing plate 6 is pushed and pulled by the push-pull mechanism, so that the multiple grooves 7 are staggered with the multiple leakage holes 4, so that the multiple leakage holes 4 are sealed, and then the above operation is repeated.
