[0041] Based on Embodiment 1, the following technical features are added: The cleaning mechanism 200 includes a driving component 201 disposed on the outside of the detection shell 100, an annular component 202 disposed on the inside of the detection shell 100, a cleaning component 203 disposed inside the detection shell 100, and a moving component 204 disposed on the inside of the detection shell 100. The annular component 202 and the moving component 204 cooperate to effectively scrape away the mucus on the outer wall of the gastroscopy catheter, avoiding the residue of mucus on the gastroscopy catheter, thereby reducing the risk of cross-infection. The driving component 201 includes a motor 201a detachably mounted on the outside of the detection shell 100. A gear 201b is fixedly connected to one end of the rotor shaft of the motor 201a through the detection shell 100. A cleaning ring 201c is rotatably connected to the center position of the slot 105. A gear 201d is fixedly connected to the outside of the cleaning ring 201c. The gear 201b meshes with the gear 201d.

[0042] Depend on Figures 3 to 9 It is known that the motor 201a is installed on the outside of the detection shell 100. The motor 201a is regulated by an external controller. The motor 201a drives the gear 1 201b to rotate. Since the gear 1 201b meshes with the gear 2 201d, it drives the cleaning ring 201c inside the gear 2 201d to rotate synchronously. The cleaning ring 201c is made of metal at the position of the gear 2 201d and of rubber at the position of the cleaning plate 203a. Multiple cleaning holes are evenly distributed on the outside of the cleaning plate 203a. The disinfectant falls from the cleaning holes onto the outside of the endoscope tube.

The gear ring 202b meshes with a gear 201b. An arc-shaped part 202c is circumferentially fixedly connected to the annular plate 202a above the gear ring 202b. As can be seen from the above, its external controller drives the gear 201b on the motor 201a to rotate. Since the gear ring 202b meshes with the gear 201b, it drives the annular plate 202a outside the gear ring 202b to rotate. At the same time as the annular plate 202a rotates, it drives the arc-shaped part 202c to rotate synchronously.

[0044] The cleaning component 203 includes a cleaning plate 203a fixedly connected to the outside of the detection housing 100. A central hole 203b is formed in the cleaning plate 203a. A cleaning ring 201c is disposed in the central hole 203b. Multiple sets of first water outlet holes 203c are arranged circumferentially in the horizontal direction on the inner side of the cleaning plate 203a.
