<p><P>PROBLEM TO BE SOLVED: To provide a dental stain remover where large displacement vibration is obtained by a brush holder without expanding the amplitude of vibration, and heat is not generated at the part of a brush. <P>SOLUTION: Regarding the dental stain remover, the brush 12 is implanted to the tip of the brush holder 11 mounted to one end of the diaphragm of a bimorph vibrator mounting a piezoelectric vibrator 13 respectively on both sides of the diaphragm 8. By applying vibration output to the piezoelectric vibrator, the brush holder connected to the diaphragm is vibrated in an orthogonal direction with respect to the brush by the vibration of the bimorph vibrator. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
