ERGONOMIC SEMI-AUTOMATIC ROTATABLE TOOTHBRUSH APPARATUS

摘要

Embodiments include a toothbrush apparatus including an ergonomic handle portion having an axis. The apparatus also includes semi-automatic rotatable bristles disposed in a removable brush block. The apparatus further includes a brush block disposed at a proximal end of a brush block arm and a rotatable brush block arm disposed in a proximal end of a coupling joint. An axis of the brush block arm is angled between 90° to 120° with respect to the axis of the ergonomic handle portion. The coupling joint is coupled at a distal end to a rotor portion configured for rotation about the axis of the ergonomic handle portion. The coupling joint is configured as a double Cardan joint.
