After the fluid pressure is reduced, the spray head 1 is aligned to teeth or slits between teeth to be cleaned, and under the condition of direct vision, the adjusting switch 61 is adjusted to adjust the flow and speed of water flow sprayed out of the spray head 1 to the degree of good cleaning effect and comfort, and then the teeth and the oral cavity are cleaned under the condition of direct vision.

In this embodiment, the nozzle 1 of the spray gun 2 can observe the size and the speed of the fluid sprayed out of the nozzle 1 in real time under the direct-view condition in the visual field of the observation system 24 of the oral cavity observation instrument 200, so as to adjust the water volume, clean teeth and oral cavity under the direct-view condition, and take pictures and record the pictures of the cleaning process, thereby being safer and more reliable in use.

It should be noted that the structures disclosed and described herein may be replaced by other structures having the same effect, and the embodiments described herein are not the only structures for implementing the present invention. Although preferred embodiments of the present invention have been shown and described herein, it will be apparent to those skilled in the art that these embodiments are merely illustrative and that numerous changes, modifications and substitutions can be made without departing from the invention herein, and it is intended that the scope of the invention be defined by the spirit and scope of the appended claims.
