Two non-contact level sensors, standard level sensor 346 and overflow level sensor 345, are provided on the side walls of each of the rinse tank 417.

Leak detection, as shown in fig. 1, 9, 12: firstly, clean air filtered by the filter 335 enters the air pump 334 through the pipeline L20, flows through the pressure reducing valve 333 and enters the air valve 332; then flows through pressure sensor 331 and enters leak detection port 213 of suitcase 100 via line L36; when the pressure sensor 331 detects that the injected air pressure is consistent with the pressure measurement parameter read by the mirror body card reader (423) from the mirror body identification card 222, the air valve 332 is closed, and the air pump 334 stops working; the whole mirror body starts to enter a pressure maintaining state, if the pressure is reduced within a specified time during the pressure maintaining period, the damage of the mirror body is indicated, error information is fed back to the control system and is warned on the main control display screen 405, as shown in fig. 1, meanwhile, the working indicator lamp 416 alarms in red, and the subsequent working of the decontamination groove 417 is stopped; the normal endoscope is measured in the other decontamination groove 417, and the endoscope is not affected by the error of the decontamination groove 417, and the subsequent flow is continued; if the pressure does not drop within the prescribed time during the pressure maintaining period, which means that the mirror body is not damaged, the air valve 332 is opened, the pressure reducing valve 333 starts to work, the pressure is released, the pressure in the mirror body is restored to normal pressure, and the next cleaning is continued. Secondly, the leak detection function can be set for automatic leak detection for a plurality of times in different cleaning and disinfection stages through a control system, so that the safety of the cleaning and disinfecting process of the endoscope is ensured, once the phenomenon of breakage and air leakage of the endoscope is found in the middle of cleaning and disinfecting, the machine stops all cleaning and disinfecting operations with the endoscope to be detected in a pressure maintaining state, liquid in the suitcase 100 is rapidly emptied, and the phenomenon that the endoscope invades the liquid to expand the damage in the endoscope body is avoided.

Cleaning, as shown in fig. 1 and 12: firstly, the valves 302, 316, 332, 336, 339, 340, 344, 349, 350, 351, 353 are closed, the waterway valves 352, 301, 303, 307 are opened, the three-way valve 309 keeps the pipeline L22 unblocked, and the water pump 311 starts to work; the cold water pipe L16 is filled with cold water and flows through the valve 352, and at the same time, the hot water pipe L15 is filled with hot water and flows through the valve 301, the hot water and flows through the valve 303, the mixed water pipe L17, the water flow flows into the pipe L14, the water is filtered by the filter 304 and then flows through the pressure reducing valve 305 to be pressure-controlled, the water flows through the temperature sensor 306 and flows into the manifold L18, the water flows through the valve 307, the water flows through the flow sensor 308, the three-way valve 309, the pipe L22, the water pump 311 is connected to the transfer pipe L24, and the water is pumped into the main injection port 210 of the suitcase 100 through the pipe L35. When the flow sensor 308 detects that the water amount reaches the set water amount, the valve 307 is closed. The invention can also be used for injecting cold water or hot water independently according to the cleaning requirement. Next, the valves 349 and 356 are opened, the cleaning agent flows into the line L22 through the valve 356, the flow sensor 347 and the valve 349 via the line L11, the transfer line L24 enters the water pump 311, and the cleaning agent is pumped into the main injection port 210 of the suitcase 100 via the line L35, and after the flow sensor 347 detects a predetermined flow rate, the valves 349 and 356 are closed, and the water pump 311 stops working, thereby mixing the cleaning agent with the water in the suitcase 100. In order to clean the internal tube of the endoscope, the water flow and the cleaning agent which enter the tube L35 via the water pump 311 enter the three-way valve 312 via the manifold L27, turn to the tube L28, enter the pouring port 211 of the suitcase 100, and wash the tube inside the endoscope. Again, when the mixed cleaning solution in suitcase 100 reaches the set volume, pump 341 begins to operate, valve 340 opens, three-way valve 342 keeps line L27 clear, three-way valve 312 keeps line L28 clear, mixed cleaning solution in suitcase 100 enters manifold L25 through main drain 225 via line L30, flows through valve 340 into three-way valve 342, flows through line L27 into pump 341, flows through line L27 into three-way valve 312, turns over line L28 into perfusion port 211 of suitcase 100, and cyclically flushes the internal lines of the endoscope until the cleaning procedure is completed. Fourth, when the mixing pump 341 is started by the water and the cleaning agent in the suitcase 100, and simultaneously the valve 336 is opened and the valve 351 is closed; air filtered by the high-efficiency filter 322 enters the air storage chamber 320 through the air compressor 321, gas is transferred into the manifold L26 through the pressure reducing valve 319 by way of the gas pipeline L21, passes through the valve 336 and the check valve 337 and enters the air supplementing port 226, and the generated bubbles can turn the mixed cleaning liquid in the suitcase to continuously wash the outer surface of the endoscope body until the cleaning process is finished. Wherein vent 103 is always open during liquid injection into suitcase 100 and the cleaning process, maintaining a normal pressure within suitcase 100; the high pressure gas within suitcase 100 flows through relief valve 327 via vent 103, and through check valve 328, into line L19, avoiding leakage of the chemical aerosol. It should be noted that because of the various volumes of the endoscope being cleaned, the standard level sensor 346 monitors the normal operating water level within the suitcase 100 as the mixed cleaning solution is being injected into the suitcase 100 and stops pumping after reaching the standard level. For safety, the invention also provides an overflow level sensor 345, and when the liquid level reaches the overflow level, valves 316, 339, 318 will open, pass through line L30 to line L13, and drain the liquid from suitcase 100 through valve 318 by water pump 317. Further, the detergent box is provided with a non-contact lowest level liquid level sensor 325, when the liquid level change is monitored and the lowest liquid level is reached, a decontamination groove 417 which cannot be pumped by the detergent liquid is displayed on the main control display screen 405, meanwhile, the working indicator lamp 416 alarms in red and stops the work of invoking the decontamination groove of the detergent liquid, and the decontamination grooves in other works can continue to work. The cleaner box is also connected with a check valve 324 connected with a filter 323 to supplement air to ensure pressure balance in the cleaner box.

Because of the various volumes of the sterilized endoscopes, when the normal operating water level in suitcase 100 is monitored by standard level sensor 346 and reaches the standard level during the injection of the mixed cleaning solution into suitcase 100, the corresponding pumping operation is stopped, overflow level sensor 345 is provided for safety, valves 316, 339, 318 are opened after the liquid level reaches the overflow level, and the liquid is transferred through line L30 to line L13 and is drained from suitcase 100 through valve 318 by water pump 317.
