This discipline not only embodies strong practical operability, but also shows a high degree of comprehensiveness and interdisciplinary characteristics, requiring practitioners to have cross-disciplinary knowledge integration and application capabilities.

[0003] In the current development of oral medicine, irrigators, as an innovative oral cleaning auxiliary device, have received extensive attention and application due to their unique advantage of using the impact force generated by pulsed water flow to effectively remove sticky substances or residues on the surface of teeth, deep in the teeth, and in the oral cavity that are difficult to reach. In order to further improve the cleaning effect, users usually add specially formulated medicine or mouthwash to the irrigator, using the dual effects of chemical action and physical flushing of these liquids to provide comprehensive and in-depth cleaning care for teeth and oral cavity.

[0043] From the above, we can know that:

[0044] The present invention is aimed at the technical problem that despite the wide variety of types, most irrigators are still relatively simple in structure, mainly relying on water pumps and their control systems to perform oral cleaning tasks, and lacking real-time monitoring of the oral cavity, which to a certain extent limits the improvement of their cleaning efficiency and user experience; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0045] The electrical components in this device are all existing technologies, and their models are only one of them. As long as the electrical components can achieve the purpose of this device, they can be used. All electrical components in the device are connected to their adapted power supplies through wires, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the working sequence. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and no longer explains the electrical control;

[0046] During use, a proper amount of liquid medicine or cleaning liquid is added by opening the sealing cap on the liquid filling port 3, and then the sealing cap is covered, and then the hoop is pressed, so that the hoop pushes the force-applying rotating head 29 and the central shaft 32 to move, and then the central shaft 32 drives the matching disk 27 to squeeze the reset spring 26 to contract, until the first annular teeth 28 are separated from the second annular teeth 31, and then the force-applying rotating head 29 is rotated, so that the force-applying rotating head 29 drives the hoop and the flushing nozzle 2 to rotate, and the force-applying rotating head 29 is released after the adjustment is completed. At this time, the elastic force generated by the matching disk 27 pushes the matching disk 27 and the first annular teeth 28 to move and reset, until the first annular teeth 28 are meshed with the second annular teeth 31 again, and the angle limit of the flushing nozzle 2 can be completed;

[0047] Then, the flushing body 1 is started, so that the pump in the flushing body 1 transmits the medicine or cleaning liquid to the flushing nozzle 2 through the connecting hose 25, and the liquid is sprayed out through the end of the flushing nozzle 2 to clean the patient's mouth. During the cleaning process, the micro motor 10 is started, so that the micro motor 10 drives the first bending arm 11 to rotate, and then the first bending arm 11 drives the first docking rod 12 to flip, so that the second stabilizing ring 15 drives the bracket 6 and the anti-fog camera 5 to adjust the angle and direction, so that the anti-fog camera 5 can feedback the environment in the oral cavity to the display 21, which is conducive to the operator to perform more accurate and efficient flushing work.

[0048] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0049] The present invention uses the structural design of the auxiliary display mechanism and the convenient adjustment mechanism to facilitate the device to adjust the angle and orientation of the anti-fog camera 5, so that the anti-fog camera 5 can assist the operator to provide visual feedback on the oral environment through cooperation with the display 21, so that the flushing nozzle 2 can flush the oral cavity more accurately, and at the same time, the angle of the flushing nozzle 2 can be adjusted, so as to achieve a more accurate, efficient and comfortable oral cleaning experience.
