PROBLEM TO BE SOLVED: To provide oral cavity cleaning equipment 1 capable of effectively performing both removal of dirt and dental plaque adhering to teeth, and decomposition (sterilization) of causative bacteria of a decayed tooth and a periodontal disease present in an oral cavity only by a very simple operation.SOLUTION: Oral cavity cleaning equipment (1) includes: a mouthpiece part (10) that a user puts into the oral cavity together with liquid (L) a vibrator (11) for vibrating the mouthpiece part (10) a vibration generation part (31) for generating an electric signal to cause the vibrator (11) to generate vibration by an ultrasonic wave control means (33) for controlling the vibration generation part (31) an electric power supply part (35) for supplying electric power for driving the vibration generation part (31) and the control means (33) and an operation part (37) that the user operates. The oral cavity is cleaned when ultrasonic vibration of the mouthpiece part (10) propagates to the entire oral cavity through the liquid (L) put into the mouth.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2017,JPO&INPIT【課題】非常に簡単な動作のみで、歯に付着した汚れや歯垢の除去と口腔内に存在する虫歯や歯周病の原因菌の分解(殺菌)との両方を効果的に行うことができる口腔内洗浄装置1を提供する。【解決手段】使用者が液体(L)と共に口腔内に含むためのマウスピース部(10)と、マウスピース部(10)を振動させる振動子(11)と、振動子(11)に超音波による振動を発生させるための電気信号を生成する振動発生部(31)と、振動発生部(31)を制御するための制御手段(33)と、振動発生部(31)び制御手段(33)を駆動するための電源を供給する電源供給部(35)と、使用者が操作する操作部(37)とを備える口腔内洗浄装置(1)である。マウスピース部(10)の超音波振動が口に含んだ液体(L)を介して口腔内の全体に伝播することで該口腔内の洗浄が行われる。【選択図】図5
