[0039] With reference to Figure 1 , Figure 4 , Figure 7The top cover 4 is provided with two groups, so that the two groups of top covers 4 can clamp the top end of the endoscope insertion tube through the unfolding and closing state. The inner surfaces of the two groups of top covers 4 are fixedly connected with rubber pads 17, so that the two groups of top covers 4 can be more stable when clamping the top end of the endoscope insertion tube. Not only can the rubber pads 17 prevent damage to the surface of the endoscope insertion tube, but also ensure that the cleaning barrel 7 can prevent the endoscope insertion tube from rotating when rotating and cleaning the outer surface of the endoscope insertion tube. The two groups of top covers 4 are fixedly connected through bolts, so that the two groups of top covers 4 can always clamp the top end of the endoscope insertion tube when closed. The inner surface of the inclined block 14 is provided with an inclined groove at the top end, and the inner surface of the inclined groove is in contact with a latch 15. When the latch 15 is inserted into the inner surface of the inclined block 14 at the top end, the inclined surface of the latch 15 can be pressed by the inclined surface of the inclined groove, so that the latch 15 drives the inclined block 14 to move upward, thereby releasing the fixing of the cleaning brush 10. The outer surface of the latch 15 is slidably connected with the inner surface of the top end of the cleaning barrel 7, so that the latch 15 can move horizontally along the inner surface of the top end of the cleaning barrel 7. The first gear 11 and the second gear 12 are each provided with two groups, so that the two groups of second gears 12 can simultaneously drive the top end and the bottom end of the cleaning barrel 7 to rotate when rotating, thereby balancing the rotating force, improving the stability of the system, reducing vibration, and ensuring that the equipment runs more smoothly. The two groups of second gears 12 are fixedly connected with the outer surface of the transmission rod 5, so that the transmission rod 5 can simultaneously drive the two groups of second gears 12 to rotate.

[0040] Working principle: when using the cleaning device, first release the fixing of the two groups of top covers 4, then vertically place the endoscope insertion tube inside the cleaning barrel 7, then close the two groups of top covers 4, and then fix them through bolts. When the two groups of top covers 4 are closed, they clamp and fix the top end of the endoscope insertion tube. Then continuously feed the cleaning liquid into the spray head 16 through the water inlet pipe on the top cover 4, so that the cleaning liquid flows from the top end to the bottom end of the endoscope insertion tube. Then start the motor 2 to drive the transmission rod 5 to rotate, so that the transmission rod 5 drives the two groups of second gears 12 to rotate, and the rotating drum 6 rotates due to the meshing of the second gear 12 and the first gear 11. When the rotating drum 6 rotates, it drives the cleaning barrel 7 to rotate, and the cleaning barrel 7 drives the eight groups of cleaning brushes 10 to rotate and clean the surface of the endoscope insertion tube. When the cleaning is completed, stop the motor 2 and the feeding of the cleaning liquid, then release the fixing of the two groups of top covers 4, so that the two groups of top covers 4 expand outward, and finally take out the endoscope insertion tube that has been cleaned.

[0041] When the cleaning brush 10 needs to be replaced, the two sets of top covers 4 are first unfolded to the designated position, and then the handle 8 is pulled to drive the cleaning cylinder 7 to move vertically along the inner surface of the rotating cylinder 6, and the sliding block 18 moves vertically along the inner surface of the sliding groove 13. When the sliding block 18 moves to the top end of the sliding groove 13, the cleaning cylinder 7 is counterclockwise rotated to drive the sliding block 18 to rotate along the arc-shaped groove 131, so that the cleaning cylinder 7 remains extended out of the rotating cylinder 6. Then the latch 15 is inserted into the top end of the cleaning cylinder 7, so that the inclined surface of the latch 15 presses the inclined groove of the inclined block 14, and drives the inclined block 14 to move vertically, thereby releasing the fixing of the cleaning brush 10. Then the brush holder 9 is pushed outward to drive the cleaning brush 10 to unfold outward, and then the old cleaning brush 10 is pulled outwards. Then the new cleaning brush 10 is inserted along the top end of the brush holder 9, and then the brush holder 9 is pushed upwards to drive the cleaning brush 10 to be embedded into the inner surface of the cleaning cylinder 7. When the cleaning brush 10 is embedded into the cleaning cylinder 7, the top end of the cleaning brush 10 presses the inclined surface at the bottom end of the inclined block 14, so that the inclined block 14 moves upwards. When the inclined block 14 moves to the appropriate position, the inclined block 14 moves downwards due to gravity and is clamped with the top end of the cleaning brush 10, so that the cleaning brush 10 is fixed to the inner surface of the cleaning cylinder 7. Then the cleaning cylinder 7 is clockwise rotated to drive the sliding block 18 to move to the right side of the arc-shaped groove 131. Then the cleaning cylinder 7 moves to the inside of the rotating cylinder 6 due to the downward movement of the sliding block 18 along the sliding groove 13.

[0042] When the cleaning cylinder 7 needs to be removed, the sliding block 18 is moved to the arc-shaped groove 131, and then the cleaning cylinder 7 is rotated to drive the sliding block 18 to rotate to the leftmost side of the arc-shaped groove 131. Then the cleaning cylinder 7 is pulled upwards to move upwards along the through groove 132, so that the cleaning cylinder 7 can be removed. When the cleaning cylinder 7 is installed, the two sets of sliding blocks 18 are inserted into the top end of the through groove 132, and then the cleaning cylinder 7 is clockwise rotated to drive the sliding block 18 to move into the sliding groove 13, and then the cleaning cylinder 7 is inserted into the rotating cylinder 6.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
