When different samples are needed to be pumped, the water inlet end of the water pumping mechanism 3 is placed at other sampling water areas, and then the above steps are operated to pump different samples into different container assemblies 5. With the rotation of the barrel 21, the container assemblies 5 storing the samples can be discharged from the corresponding discharge ports 12 in sequence, and the staff only needs to take away the discharged container assemblies 5 and detect them at the detector.

In addition, the motor 43 is provided with a controller and a timer. The staff can select different times and then control the motor 43 to start and stop at the corresponding time by the controller.

[0022] In a specific implementation, the motor 43 drives the rotating shaft 44 to rotate after being started. At this time, the incomplete bevel gear 45 and the incomplete gear 46 rotate synchronously. First, the toothed side of the incomplete gear 46 is in meshing cooperation with the rack 47, thereby driving the rack 47 to rise, so that the water guide platform 34 and the water injection head 35 rise together to the position that the water injection head 35 is away from the corresponding placement cavity 22. Subsequently, the toothed side of the incomplete bevel gear 45 rotates to be in meshing cooperation with the gear teeth on the adjusting ring 41, thereby driving the adjusting ring 41 to rotate the barrel 21 to the position that the corresponding placement cavity 22 moves to the bottom of the output end of the water pumping mechanism 3. After the rotation is completed, the toothless side of the incomplete bevel gear 45 rotates to face the adjusting ring 41. Therefore, the adjusting ring 41 does not rotate in this time period.
