TOOTHBRUSH Russian patent published in 1998 - IPC

FIELD: sanitary and hygienic articles. SUBSTANCE: toothbrush has handle and head part with permanent magnet. Block with bristles is mounted in head part for reciprocation along toothbrush axis. Block is manufactured from current-conductive material. When user cleans his teeth, block intersects magnetic field lines of permanent magnet and, as a result, electromotive force is generated in block to create potential difference between head part and surface of teeth under cleaning process. Potential difference facilitates effective removal of dental deposit from teeth surface. Permanent magnet acts upon gum tissues to improve blood circulation in it. EFFECT: increased efficiency, simplified construction and convenient usage. 1 dwg
