[0018]To better achieve the objectives of this invention, the adjustable inlet water assembly of the water outlet component is connected to the evaporator of the chiller, and the adjustable reflux assembly is also connected to the evaporator. The liquid dispensing assembly adds citric acid solution to the evaporator of the chiller through a water injection pipe. A water pump draws water from the evaporator through the adjustable inlet water assembly into the adjustable reflux assembly, and then back into the evaporator, facilitating thorough mixing of the citric acid solution with the water. Next, the adjustable reflux assembly is connected to the adjustable drain assembly, which in turn connects to the cooling pipes of the medical laser equipment. The water pump draws water from the evaporator through the adjustable inlet water assembly into the adjustable reflux assembly, then into the adjustable drain assembly, and finally into the cooling pipes of the medical laser equipment. The water then returns to the evaporator through a return water pipe, circulating for 30-90 minutes to facilitate the use of the medical laser equipment. The cooling pipes are descaled; after descaling, the regulating reflux assembly and the chiller's evaporator remain connected. The liquid distribution assembly adds sodium bicarbonate solution to the chiller's evaporator. The water pump draws water from the chiller's evaporator into the regulating reflux assembly through the regulating inlet assembly, and then into the chiller's evaporator. The sodium bicarbonate solution and the water in the chiller's evaporator are fully mixed and neutralized until the pH value of the water in the chiller's evaporator is between 6 and 9 as monitored by the pH monitor. Then, the regulating reflux assembly is connected to the regulating drain assembly, which in turn is connected to the waste liquid collection tank. The water pump draws water from the chiller's evaporator into the regulating drain assembly through the regulating inlet assembly, and then into the regulating reflux assembly through the regulating drain assembly, before finally discharging the water into the waste liquid collection tank through the regulating drain assembly, facilitating the direct discharge of the neutralized water after descaling.When water is discharged from the evaporator of the chiller, the water level monitoring component detects the water level in the evaporator. When the water level in the evaporator reaches its lowest point, the regulating inlet component connects to the deionized water source, and the regulating reflux component connects to the evaporator. The water pump draws deionized water through the regulating inlet component into the regulating reflux component, and then into the evaporator until the water level monitoring component detects that the water level has reached its highest point. At this point, the regulating inlet component connects to the evaporator. The system connects the regulating reflux assembly to the regulating drainage assembly, which in turn connects to the medical laser equipment. Water is pumped from the chiller's evaporator through the regulating inlet assembly into the regulating reflux assembly, then into the regulating drainage assembly, and finally into the cooling pipes of the medical laser equipment. The water then returns to the chiller's evaporator via the return pipe, circulating for approximately 10-15 minutes to flush the cooling pipes of the medical laser equipment. Finally, the regulating drainage assembly connects to the hospital's dedicated wastewater network. The pump draws water from the chiller's evaporator through the adjustable inlet assembly into the adjustable drain assembly, and then discharges it into the hospital's dedicated wastewater network. This process is repeated three times to flush the cooling pipes of the medical laser equipment. While the water is being discharged from the chiller's evaporator, the water level monitoring assembly detects the water level. When the water level reaches its lowest point, the adjustable inlet assembly connects to the deionized water source, and the adjustable reflux assembly connects to the chiller's evaporator. The pump then draws deionized water through the adjustable inlet assembly into the adjustable reflux assembly, and then into the chiller's evaporator until the water level monitoring assembly detects the highest point. This allows for the addition of a set amount of water to the chiller's evaporator. The adjustable inlet assembly and the chiller's evaporator remain connected, the adjustable reflux assembly connects to the adjustable drain assembly, and the adjustable drain assembly connects to the medical laser equipment. The medical laser cooling device is then adjusted to a state ready for cooling the medical laser equipment. In summary, this method enables automated descaling of medical laser cooling devices, eliminating the need for manual supervision during extended descaling processes, which is beneficial for practical use.

The water pump 58 then operates through the water supply pipe 55 and the second control valve 510 of the regulating water inlet component. 6. Deionized water is pumped into the second connecting pipe 59 and the fourth connecting pipe 512 of the regulating reflux assembly, and then into the evaporator of the chiller 1, until the water level monitoring assembly detects that the water level has reached the highest point. At this point, the second control valve 56 of the regulating inlet assembly connects to the first connecting pipe 57, which in turn connects to the evaporator of the chiller 1. The third control valve 510 of the regulating reflux assembly connects to the third connecting pipe 511 of the regulating drain assembly, which then connects to the outlet pipe 5. 1. The outlet pipe 51 connects to the medical laser equipment. The water pump 58 draws water from the evaporator of the chiller 1 through the second control valve 56 and the first connecting pipe 57 of the regulating inlet assembly. The water then enters the second connecting pipe 59 of the regulating reflux assembly, then the third connecting pipe 511 and the outlet pipe 51 of the regulating drain assembly, and finally the cooling pipe of the medical laser equipment. The water then returns to the evaporator of the chiller 1 through the return pipe 2. The self-circulating electric heater circulates the cooling pipe of the medical laser equipment for 10-15 minutes. The process involves rinsing, then the first control valve 53 of the adjustable drainage assembly is connected to the drain pipe 54, which in turn is connected to the hospital's dedicated wastewater network. The water pump 58 draws water from the evaporator of the chiller 1 through the second control valve 56 and the first connecting pipe 57 of the adjustable inlet assembly into the second connecting pipe 59 of the adjustable drainage assembly, and then discharges it into the hospital's dedicated wastewater network through the third connecting pipe 511 and the drain pipe 54 of the adjustable drainage assembly. This process is repeated three times to achieve the rinsing treatment of the cooling pipes of the medical laser equipment. When water is discharged from the evaporator of chiller 1, the water level monitoring component detects the water level in the evaporator. When the water level in the evaporator reaches its lowest point, the second control valve 56 of the regulating inlet water component connects to the water supply pipe 55, which in turn connects to the deionized water source. The third control valve 510 of the regulating reflux component connects to the fourth connecting pipe 512, which is connected to the evaporator of chiller 1. The water pump 58 then draws deionized water into the regulating reflux component through the water supply pipe 55 and the second control valve 56. The fourth connecting pipe 512 then enters the evaporator of the chiller 1 until the water level monitoring component detects that the water level has reached the highest point, so that the evaporator of the chiller 1 can be filled with a set amount of water. Then, the second control valve 56 of the regulating water inlet component is connected to the first connecting pipe 57, and the first connecting pipe 57 is connected to the evaporator of the chiller 1. The third connecting pipe 511 of the regulating reflux component is connected to the outlet pipe 51 of the regulating drain component, and the outlet pipe 51 of the regulating drain component is connected to the medical laser equipment. The medical laser cooling device is adjusted to the state of being ready to cool the medical laser equipment.
