<p><P>PROBLEM TO BE SOLVED: To provide an ultrasonic oral care article capable of improving the degree of freedom in terms of the design of an ultrasonic oscillation part, preventing an unpleasant feeling due to temperature rise and efficiently cleaning the mouth by supplying less liquid enough to maintain transmission efficiency without generating an air layer in the liquid inside a liquid pool part and the supply path of the liquid in a neck part, with excellent handleability and the high degree of freedom in terms of the design. <P>SOLUTION: For this ultrasonic oral care article, a supply path 52 of the liquid from a handle body 10 to the discharge part 2 of a head body 11 through the inside of a neck part 12 is provided, an ultrasonic oscillation part 4 for irradiating the liquid with ultrasonic energy is provided inside the handle body 10, and ultrasonic waves transmitted with the liquid as a vibration transmission medium are transmitted to the discharge part 2 while being reflected inside the supply path 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
