Electric toothbrush

Abstract

The present disclosure relates to an electric toothbrush, including: a handle assembly including a measurement module; and a brush head assembly provided with a measured block to be identified. The brush head assembly is in contact with the handle assembly, and the measurement module is electrically connected to the measured block. A difference of the measured block forms a signal difference measured by the measurement module, and a type of a brush head is identified according to the signal difference. Thus, the electric toothbrush is capable of achieving the function of identifying the type of the brush head on the basis of reducing production costs and design costs.

Dependencies are inferred from the claim text.
