[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Part of the liquid in the liquid supply tank 1 flows into the measuring tube 2, and the float cotton part 13 moves up due to the rise of the liquid. At the same time, the float cotton part 13 moves down due to the drop of the liquid. The amount of liquid in the liquid supply tank 1 is known by the length of the measuring rod 12 exposed outside the measuring tube 2, so as to judge whether it is necessary to fill the liquid supply tank 1 with liquid. However, in the process of the float cotton part 13 moving up and down, the inside of the measuring tube 2 can be simply cleaned.

[0024] See also Figure 3-4A rotating rod 11 is rotated at the middle position and near the bottom of the liquid supply box 1, and a driving motor 3 for driving the rotating rod 11 to rotate is installed on one side of the liquid supply box 1. The model of the driving motor 3 can be Y90S-2, and a rectangular paddle 10 is fixed to the outer wall of the rotating rod 11, and the rectangular paddle 10 and the liquid suction pipe 9 are staggered. During the rotation of the rotating rod 11, the rectangular paddle 10 does not knock the liquid suction pipe 9. The driving motor 3 is started, and the output shaft of the driving motor 3 drives the rotating rod 11 to rotate. At this time, the rectangular paddle 10 rotates with the rotating rod 11 as the center point. The mixed liquid stored in the liquid supply box 1 can be stirred and mixed by using the rectangular paddle 10.

[0025] See also Figure 5-6 The outer wall of the liquid supply box 1 is fixedly connected with a connecting part 17, and a plug-in groove 15 is provided at one end of the connecting part 17 away from the liquid supply box 1. The bottom end of the measuring tube 2 is fixed with a plug-in part 14 plugged with the connecting part 17 through the plug-in groove 15. The size of the plug-in part 14 is equal to the size of the plug-in groove 15. After the plug-in part 14 and the connecting part 17 are plugged, the plug-in part 14 and the inner wall of the plug-in groove 15 fit tightly, thereby achieving a sealing effect; wherein, a reserved hole is embedded in the outer wall of the plug-in part 14, and the reserved hole does not penetrate the plug-in part 14. The outer wall of the connecting part 17 penetrates a T-shaped plug 16 plugged with the plug-in part 14 through the reserved hole. In addition, a spring 18 is fixed to the outside of the T-shaped plug 16 on the outer wall of the connecting part 17, and one end of the spring 18 is fixedly connected to the outer wall of the connecting part 17, and the T-shaped plug 16 forms a reset structure through the spring 18. When the measuring cylinder 2 and the connecting part 17 are docked, the plug-in part 14 is inserted into the plug-in slot 15, and the T-shaped plug-in pin 16 is loosened. The T-shaped plug-in pin 16 is inserted into the reserved hole on the outer wall of the plug-in part 14 under the action of the spring 18 to fix the plug-in part 14 and the connecting part 17, thereby facilitating the installation and removal of the measuring cylinder 2 and the liquid supply box 1. The input ends of the liquid pump 6 and the drive motor 3 are connected to the output end of the external controller by wires, and the liquid pump 6 and the drive motor 3 are reasonably controlled by the externally connected controller in the later stage.

[0026] Working principle: firstly, the measuring tube 2 and the liquid supply box 1 are connected, the plug-in part 14 is aligned with the plug-in groove 15 and squeezed against each other, and the plug-in part 14 is inserted into the plug-in groove 15. At this time, the T-shaped pin 16 is plugged into the plug-in part 14 through the action of the spring 18, and the plug-in part 14 and the connecting part 17 are fixedly connected. Then, the liquid supply box 1 is filled with liquid, and a small amount of liquid flows into the measuring tube 2. When the liquid in the measuring tube 2 moves upward, the liquid pushes the float cotton part 13 upward, and the amount of liquid in the liquid supply box 1 is judged by the height of the measuring rod 12 exposed outside the measuring tube 2. The liquid pump 6 is started, and the liquid in the liquid supply box 1 flows along the liquid suction pipe 9 to the threaded connection pipe 5 and then sprayed out through the spraying part 7. If a drug that increases the cleaning effect is added to the liquid later, the driving motor 3 can be started, and the output shaft of the driving motor 3 drives the rotating rod 11 to rotate. The rectangular paddle 10 is used to stir the liquid in the liquid supply box 1, so that the cleaning drug and the liquid are evenly mixed, thereby improving the cleaning effect of the endoscope in the later stage and the cleanliness of the endoscope surface.
