[0005] Furthermore, the controller is a PLC controller.

[0006] Furthermore, the distance measuring sensor is an infrared distance measuring sensor with its own power supply.

[0007] Furthermore, the drug injection port includes an upper section, a lower section, a central column and a liquid outlet, and the upper section is fixedly connected to the lower section.

[0008] There is a central column at the center of the upper end, and liquid outlet holes are evenly distributed around the central column. The lower section is a tapered pipe that runs through the upper and lower parts.
