[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Referring to Figures 1-5 , an electronic endoscope detection component includes an endoscope tip 1. An objective lens 2 is fixedly installed at the top of the endoscope tip 1. On the other side of the top of the endoscope tip 1, an air port 3 is fixedly installed. A plurality of sealing teeth 4 are fixedly installed at the top of the air port 3. A sealing plug 5 is slidably arranged inside the air port 3. The sealing teeth 4 and the sealing plug 5 are adapted to each other. A transmission mechanism is arranged inside the endoscope tip 1. The sealing plug 5 is connected to the transmission mechanism through the endoscope tip 1; after the endoscope is used, the electronic endoscope needs to be cleaned and disinfected. The air port 3 of the electronic endoscope is mainly located at the curved part of its tip and is used for functions such as water supply and air supply. During the cleaning and disinfection process, since the existing endoscope air port 3 generally does not have a blocking function, special attention needs to be paid to avoiding the condensation of proteins or other impurities from entering the inside of the air port 3, because this may cause the air port 3 to be blocked or affect the normal use of the endoscope. When the present utility model cleans the endoscope, the transmission mechanism can drive the sealing plug 5 to cooperate with the sealing teeth 4, so that the air port 3 on the endoscope tip 1 is blocked, and proteins or other impurities are prevented from entering the inside of the air port 3.

[0027] As a preferred technical solution of this embodiment, the transmission mechanism includes an adjusting screw 6. The adjusting screw 6 is fixedly installed at the bottom of the sealing plug 5. A first gear 8 is rotatably installed inside the endoscope tip 1. The lower end of the adjusting screw 6 penetrates the bottom of the air port 3 and is threadedly connected to the first gear 8. A slider 7 is fixedly installed at the bottom end of the adjusting screw 6. The slider 7 is slidably connected inside the endoscope tip 1; after the endoscope is used, the endoscope needs to be cleaned. In order to prevent the dirt generated by cleaning from entering the inside of the air port 3 and causing the air port 3 to be blocked, the first gear 8 is rotated, so that the adjusting screw 6 threadedly connected to the first gear 8 drives the sealing plug 5 to rise and engage with the sealing teeth 4 at the top of the air port 3 to seal the top of the air port 3.

[0028] As a preferred technical solution of this embodiment, a micro motor 10 is fixedly installed inside the endoscope tip 1. A second gear 9 is fixedly installed at the output end of the micro motor 10. The second gear 9 is rotatably arranged inside the endoscope tip 1. The second gear 9 meshes with the first gear 8; when the first gear 8 is rotated, the micro motor 10 controls the rotation of the second gear 9, so that the first gear 8 meshing with the second gear 9 rotates.

[0029] As a preferred technical solution of this embodiment, a support piece 13 is provided at the bottom of the slider 7. A spring 14 is fixedly installed at the bottom of the support piece 13, and the lower end of the spring 14 is fixedly connected to the inside of the endoscope tip 1. The adjusting screw 6 is supported by the support piece 13 and the spring 14, so that the pre-tightening force between the adjusting screw 6 and the first gear 8 is increased, and the stability of the sealing plug 5 inside the air port 3 is improved.

[0030] As a preferred technical solution of this embodiment, a partition piece 11 is fixedly installed inside the air port 3. The partition piece 11 is slidably connected to the top of the adjusting screw 6. A sealing ring 12 is fixedly installed at the junction of the partition piece 11 and the adjusting screw 6. An air pipe 18 is fixedly installed on the top side wall of the air port 3, and the air pipe 18 is fixedly installed inside the endoscope tip 1. The water vapor conveyed by the air pipe 18 is separated by the partition piece 11, and the sealing performance of the partition piece 11 is increased by the sealing ring 12 to prevent water vapor from leaking from the lower end of the air port 3.

[0031] As a preferred technical solution of this embodiment, a CCD image sensor 17 is provided at the bottom of the objective lens 2. The CCD image sensor 17 is fixedly installed inside the endoscope tip 1, and the CCD image sensor 17 is adapted to the objective lens 2. When observing the patient's body, in the imaging system, the objective lens 2 is responsible for focusing the external light on the photosensitive surface of the CCD image sensor 17. Specifically, the objective lens 2 forms the image of the target object on the pixel array of the CCD image sensor 17 through its optical design. In this way, the CCD image sensor 17 can capture this light and convert it into an electrical signal, and then form a digital image.

[0032] As a preferred technical solution of this embodiment, light guide beams 15 are fixedly installed on both sides of the top of the endoscope tip 1. The light guide beams 15 provide a light source for the objective lens 2.

[0033] As a preferred technical solution of this embodiment, a forceps channel outlet 16 is fixedly installed on the top of the endoscope tip 1. The forceps channel outlet 16 is a key part of the top of the endoscope tip 1, which allows doctors or operators to insert various diagnostic and therapeutic accessories (such as biopsy forceps, graspers, etc.) into the pipeline of the endoscope. These diagnostic and therapeutic accessories can extend from the outlet when passing through the forceps channel outlet 16, so as to achieve direct contact and operation on a specific area in the patient's body.
