より口腔内の自動清掃が終了する。Before using the device (that is, before starting oral cleaning), both the water supply valve 33 and the drain valve 35 are closed, and therefore the water supply pipe 37 and the drain pipe 38 are connected to the water supply tank 2, respectively.
0 and the drainage tank 21. After the mouthpiece 1 is set in the oral cavity of the patient 30 by the operation of the movable arm 19 and the mouthpiece support arm 17, the air in the pilot pipe is made to flow by operating a push button or the like as described above, and the mouthpiece is placed in a predetermined position. When it is confirmed that the water supply valve 33 is set to 1, the water supply valve 33 is opened, the mouthpiece 1 and the water supply tank 20 are communicated via the water supply pipe 37, and the mouthpiece 1 and the water supply tank 20 are pressurized by the compressed air discharged from the compressor 25. The water in the water supply tank 20 is sent into the mouthpiece l through the water supply pipe 37, and the water is sent to the mouthpiece l through the cleaning water outlet 3 of the mouthpiece 1.
It is ejected towards the tooth surface. Further, the vibration energy is supplied to the vibrator in the mouthpiece 1 from an external vibration energy source to generate vibrations, and high-frequency vibration energy is imparted to the cleaning water. On the other hand, the drain valve 35 is also opened at the same time as the water supply valve 33, and both the mouthpiece 1 and the spittoon 18 are communicated with the drain tank 21 via the drain valve 35, and the contaminated water after washing into the mouthpiece 1 and the spittoon 18 is drained into the drain pipe. 3
7 and 39 and is discharged into the drainage tank 21. After cleaning for a predetermined period of time, when the water supply valve 33 and the drain valve 35 are closed, the movable arm 19 and the mouthpiece support arm 17
moves to pull out the mouthpiece 1 from the oral cavity, thereby completing the automatic cleaning of the oral cavity.
