[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.

[0023] Example: Reference Figure 1-5 The automatic proportioning device of cleaning agent with endoscope auxiliary water supply and flushing function shown in the figure comprises a shell 1, an upper sterile cup holder 2, and a lower sterile cup holder 3. The upper sterile cup holder 2 is fixedly mounted on the side of the shell 1, and the lower sterile cup holder 3 is arranged at the bottom of the shell 1 through a lifting component. The side of the shell 1 is provided with an upper liquid outlet 15 and a lower liquid outlet 16. The bottoms of the upper liquid outlet 15 and the lower liquid outlet 16 are respectively provided with an upper nozzle 17 and a lower nozzle 18. The shell 1 is provided with A liquid extraction and delivery pump 19, an upper liquid distribution solenoid valve 20, a lower liquid distribution solenoid valve 21, and an auxiliary water supply valve 22 are provided. The liquid extraction and delivery pump 19 is connected to the upper liquid distribution solenoid valve 20, the lower liquid distribution solenoid valve 21, and the auxiliary water supply valve 22 through a four-plug pagoda connector 23. The side of the shell 1 is provided with an auxiliary water supply channel output quick-plug connector 26, a CPC quick-plug interface 27, and a power signal input interface 28. The CPC quick-plug interface 27 is connected to the liquid extraction and delivery pump 19.

[0024] With the above structure, when in use, through the setting of the liquid pump 19 and the upper liquid dispensing solenoid valve 20 and the lower liquid dispensing solenoid valve 21, the cleaning agent can be transmitted to the sterile cups placed on the upper sterile cup holder 2 and the lower sterile cup holder 3 through the upper nozzle 17 and the lower nozzle 18 respectively through the control program, so as to realize quantitative liquid dispensing, and through the auxiliary water supply valve 22 connected to the auxiliary water supply channel output quick plug connector 26, the auxiliary water supply pipeline of the endoscope can be perfused and cleaned. When endoscopes of different lengths need to be cleaned, the lower sterile cup holder 3 can be driven downward by the lifting assembly to adapt to the cleaning operation of endoscopes of different lengths.

[0025] like Figure 2As shown, the lifting assembly includes a fixed adapter plate 4, which is fixedly installed on the side inner wall of the shell 1 by multiple bolts, and a guide rail slider module 5 is fixedly installed on the side of the fixed adapter plate 4. A trapezoidal screw 9 is rotatably installed on the bottom inner wall of the guide rail slider module 5. The top of the trapezoidal screw 9 extends to the outside of the guide rail slider module 5 and is provided with a driving unit. A translation slider 6 is threadedly installed on the trapezoidal screw 9, and the translation slider 6 is slidably installed on the guide rail slider module 5. A telescopic shaft fixing seat 12 is fixedly installed on the side of the translation slider 6, and a telescopic shaft 13 is fixedly installed on the bottom of the telescopic shaft fixing seat 12. The lower sterile cup holder 3 is fixedly sleeved on the bottom end of the telescopic shaft 13. In this way, the rotation of the trapezoidal screw 9 can drive the telescopic shaft fixing seat 12 and the telescopic shaft 13 to realize lifting and lowering movement, thereby driving the lower sterile cup holder 3 to lift and lower movement synchronously.

[0026] Specifically, when the height of the sterile cup holder 3 needs to be adjusted, the trapezoidal screw 9 is driven to rotate by the driving unit, thereby driving the translation slider 6 to achieve lifting movement under the action of the thread and the limiting action of the guide rail slider module 5, thereby driving the telescopic shaft fixing seat 12 and the telescopic shaft 13 to rise and fall synchronously.

[0027] like Figure 2 As shown, the driving unit includes a stepper motor 8, a motor fixing plate 7 is fixedly installed on the side of the guide rail slider module 5, the stepper motor 8 is fixedly installed on the bottom of the motor fixing plate 7, and a synchronous pulley 10 is fixedly sleeved on the stepper motor 8 and the trapezoidal screw 9. A synchronous belt 11 is tensioned and installed on the two synchronous pulleys 10. The advantage of this arrangement is that through the setting of the stepper motor 8, the trapezoidal screw 9 can be driven to rotate under the action of the two synchronous pulleys 10 and the synchronous belt 11.

[0028] Specifically, when the trapezoidal screw 9 needs to be rotated, the stepper motor 8 is started to drive one of the synchronous pulleys 10 to rotate, thereby driving the other synchronous pulley 10 and the trapezoidal screw 9 to realize the rotation function through the transmission action of the synchronous belt 11, and the rotation effect is stable.

[0029] like Figure 2 As shown, a travel limit switch 14 is fixedly installed on the side of the motor fixing plate 7, and the travel limit switch 14 is adapted to the translation slider 6. Such an arrangement can detect the position of the translation slider 6 after sliding.

[0030] Specifically, by setting the travel limit switch 14 , the position of the translation slider 6 after sliding can be monitored, thereby realizing synchronous detection of the height of the lower sterile cup holder 3 .

[0031] like Figure 1As shown, an upper photoelectric sensor 24 and a lower photoelectric sensor 25 are arranged on the side of the shell 1, and the upper photoelectric sensor 24 and the lower photoelectric sensor 25 are respectively matched with the upper sterile cup holder 2 and the lower sterile cup holder 3. The advantage of such arrangement is that through the arrangement of the upper photoelectric sensor 24 and the lower photoelectric sensor 25, it is possible to detect whether the sterile cup is placed in place, thereby avoiding waste of the sterile cup due to alignment.

[0032] Specifically, after the sterile cups are placed on the upper sterile cup holder 2 and the lower sterile cup holder 3, their positions can be detected by the upper photoelectric sensor 24 and the lower photoelectric sensor 25. The rehydration instruction will be executed only after confirming that the sterile cups are in place.

[0033] like Figure 5 As shown, a cleaning agent bottle fixing seat 29 is provided on the side of the housing 1, a cleaning agent bottle 30 is provided in the cleaning agent bottle fixing seat 29, the cleaning agent bottle 30 is connected to the CPC quick-insert interface 27, and a liquid level switch is provided in the cleaning agent bottle 30. With this arrangement, the cleaning agent bottle 30 can be fixed, and the internal residual amount can be observed through the liquid level switch.

[0034] Specifically, the detergent bottle 30 can be placed and fixed by the detergent bottle fixing seat 29 to avoid tipping, and the remaining amount in the detergent bottle 30 can be quickly observed by the liquid level switch, so as to add detergent in time.

[0035] like Figure 4 As shown, a circuit board control system 31 is provided in the housing 1, and the circuit board control system 31 is electrically connected to the stepping motor 8, the travel limit switch 14, the liquid pumping and delivery pump 19, the upper liquid distribution solenoid valve 20, the lower liquid distribution solenoid valve 21, the auxiliary water supply valve 22, the upper photoelectric sensor 24, and the lower photoelectric sensor 25. The advantage of such a configuration is that the internal components can be conveniently controlled through the configuration of the circuit board control system 31.

[0036] Specifically, by arranging the circuit board control system 31 inside the housing 1, the internal components can be centrally controlled, which is convenient for the staff to use in practice.
