Abstract
The present disclosure is directed to a low-cost toothbrush with a simple-to-manufacture design that provides a tapping motion of the brush head. In an embodiment, a dental cleaning device includes an eccentric rotating mass motor and a drive shaft mechanically coupled to the motor. A spring element is mounted to the drive shaft in a configuration in which it acts in a direction perpendicular to the axis of the drive shaft. The spring element and drive shaft form an assembly having a resonant frequency. A power source supplies to the motor power sufficient to cause the motor to operate near the resonant frequency of the assembly.
