<P>PROBLEM TO BE SOLVED: To prevent trouble by the invasion of water inward from a switch part in an interdental brush, and also to perform changeover among weak, middle and strong even during using the electric interdental brush. <P>SOLUTION: An electric interdental brush is constituted by including in a cylindrical holder 1, a battery 9, a motor 10 to be rotated with the battery 9 as a power source, and a vibration axis 6 whose distal end is finely vibrated in a perpendicular direction when receiving the rotating movement of the motor 10. Besides, a brush 4 is removably attached to the distal end of the vibration axis 6. The electric interdental brush also includes a rotary switch mechanism which is arranged on the bottom of the holder 1 to change over the power source of the motor 10 among weak, middle and strong. The electric interdental brush is used by switching the rotary switch mechanism by a tab 22, and also waterproofness is obtained by assembling an O-ring 24 with an interlock axis 23. <P>COPYRIGHT: (C)2012,JPO&INPIT |
