PROBLEM TO BE SOLVED: To provide a cleaning device capable of cleaning an oral cavity and a tooth surface at the same time only by holding equipment between teeth by a user, allowing consolidation of a polishing process and a rinsing process when cleaning the oral cavity by using a liquid in which, for example, air bubbles such as fine bubbles are generated in a plurality of numbers.SOLUTION: A cleaning device 1 which cleans an oral cavity includes a fine bubble generating part 7 which generates a plurality of fine bubbles in a hot water, a water pump 5 which delivers a hot water containing fine bubbles, and a cleaning device 9 that is housed in the oral cavity. In the cleaning device 9, a plurality of spouting openings 9c are formed in which a hot water containing fine bubbles is made to pass a passage formed inside a hollow part for spouting in the oral cavity. It has a tooth row formation part 9a following a tooth row between teeth of an upper jaw and teeth of a lower jaw. The plurality of spouting openings 9c are formed at the tooth row formation part 9c along at least one tooth row among the tooth row of the upper jaw teeth and the tooth row of the lower jaw teeth.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 例えばファインバブルのような気泡を複数発生させた液体を用いて口腔内の洗浄を行う際に、磨く工程と漱ぎの工程の一体化が可能で、使用者が器具をくわえて使用するだけで、口腔内の洗浄と歯牙表面の洗浄を一斉に行える洗浄装置を提供する。【解決手段】 口腔内を洗浄する洗浄装置1は、温水内に複数のファインバブルを発生するファインバブル発生部7と、ファインバブルを有する温水を送り出すウォーターポンプ5と、口腔内に収容される洗浄器具9を備える。洗浄器具9は、ファインバブルを有する温水を内部の中空により形成した通路内を通過させて、口腔内で噴出させる複数の噴出口9cが形成されており、上顎の歯と下顎の歯との間で歯列に沿う歯列形状部分9aを有し、複数の噴出口9cが上顎の歯の歯列及び下顎の歯の歯列の少なくとも一方の歯列に沿って歯列形状部分9cに形成されている。【選択図】 図1
