The high-pressure water pump 60 is connected to the annular closed cavity 513 on the second swirl seat 51 through a second pipe 602. The first pipe 601 is set as a soft pipe. In order to facilitate the insertion part 82 of the gastroenteroscope to pass through the circular hole 512 of the first swirl seat 35 smoothly and to facilitate the operation end 83 to pass through the circular hole 512 of the second swirl seat 51 smoothly, it is set so that the diameter of the circular hole 512 on the first swirl seat 35 is larger than the outer diameter of the insertion part 82 of the gastroenteroscope, and the diameter of the circular hole 512 on the second swirl seat 51 is larger than the radial maximum outer body size of the operation end 83 of the gastroenteroscope.

[0033] The negative pressure flushing part is used to perform negative pressure flushing on the internal channels of the insertion part 82 of the gastroenteroscope; specifically, the negative pressure flushing part includes a sealing box 61 arranged in the cleaning tank 10 and a vacuum pumping device (not shown) for evacuating the inner cavity of the sealing box 61, the sealing box 61 is fixedly connected to the inner wall of the cleaning tank 10, the vacuum pumping device is sealed and connected with the inner cavity of the sealing box 61 through a first air pipe 62, the inner cavity of the collet chuck 21 is sealed and connected with the inner cavity of the sealing box 61, an elastic rubber sheet is fixedly attached to the inner wall of the collet chuck 21 along the circumference, the elastic rubber sheet prevents external gas from entering the inner cavity of the collet chuck 21 while ensuring that the collet chuck 21 can open and close normally to clamp the probe end 81 of the gastroenteroscope, and a drain valve is provided on the lower side wall of the sealing box 61.

[0034] In this embodiment, an air pump (not shown) is further provided outside the cleaning tank 10, and the annular closed cavity 513 on the first swirl seat 35 is connected to the air pump through a flexible air pipe 71, and the annular closed cavity 513 on the second swirl seat 51 is connected to the air pump through an air pipe 72, and both the air pipe 1 71 and the air pipe 2 72 are provided with air valve switches to control the on / off of the air pipe 1 71 and the air pipe 2 72.

[0035] When the present scheme is used, the operating end 83 of the insertion part 82 of the gastroenteroscope to be cleaned is clamped with the second collet chuck 22, the lock 344 on the wiping seat 34 is opened, the upper seat 341 is flipped open, the probe end 81 of the insertion part 82 of the gastroenteroscope is passed through the circular hole 512 on the first swirl seat 35 and the lower semicircular hole 3421 on the lower seat 342 in sequence, and then the probe end 81 of the gastroenteroscope is clamped with the first collet chuck 21, and the upper seat 341 is buckled on the lower seat 342. At this time, the elastic sponge embraces and presses against the outer wall of the insertion part 82, the water outlet valves on the cleaning tank 10 and the sealing box are closed, the air valve switches on the air pipe 1 71 and the second air pipe 72 are closed, there is no water in the sealing box, and cleaning liquid is added into the cleaning tank 10 to immerse the first swirl seat 35 and the second swirl seat 51.

[0036] The driving motor 33, the high-pressure water pump 60 and the vacuum pump are operated. The driving motor 33 drives the slider 32 to move back and forth along the slide rail 31. The high-pressure water pump 60 injects high-pressure water into the annular closed cavity 513 on the first swirl seat 35 and the second swirl seat 51. When the slider 32 drives the first swirl seat 35 to move, the elastic sponge wipes off the residue on the outer wall of the insertion part 82. The high-pressure water injected into the annular closed cavity 513 flows out quickly through the water outlet 514, so that a swirl is formed at the circular hole 512 of the first swirl seat 35 and the second swirl seat 51, and the residue on the outer wall of the insertion part 82 and the surface of the operating end 83 are washed away respectively. The vacuum pump puts the sealing box in a negative pressure state, so that the cleaning liquid quickly flows through the various channels in the insertion part 82 and enters the sealing box, so as to achieve the purpose of flushing the various channels in the insertion part 82.

[0037] After cleaning, stop running the drive motor 33, the high-pressure water pump 60 and the vacuum machine, open the water outlet valves on the cleaning tank 10 and the sealing box 61 to drain the water in the cleaning tank 10 and the sealing box, then close the water outlet valve on the sealing box, open the air valve switches on the air pipe 1 71 and the air pipe 2 72, flip open the upper seat 341, run the drive motor 33, the air pump and the vacuum machine, the slider 32 drives the first swirl seat 35 to move, and the operation of the vacuum machine forces the air flow to enter the sealing box 61 through the channels in the insertion part 82 at high speed, and takes away the residual water in the channels in the insertion part 82. The operation of the air pump causes the air flow to be ejected from the water outlets on the first swirl seat 35 and the second swirl seat 51 to blow dry the water stains on the outer wall of the insertion part and the surface of the operating end 83. After drying, stop running the drive motor 33, the air pump and the vacuum machine, loosen the collet chuck 1 21 and the collet chuck 22, remove the gastroenteroscope, and manually clean the extremely small area of ​​the surface where the two ends of the gastroenteroscope are clamped.
