Electric toothbrush

The utility model belongs to the technical field of nursing devices, and particularly relates to an electric toothbrush which comprises a handle part and a head part connected to the handle part. The driving module is connected with the head part and is used for generating oscillating motion; the support module comprises a support assembly and a vibration reduction piece, the power module and the driving module are sequentially installed on the support assembly in the first direction and electrically connected through the vibration reduction piece, and the two ends of the vibration reduction piece are connected to the driving module and the power module respectively. Therefore, the vibration transmitted from the driving module to the power supply module is weakened. According to the electric toothbrush provided by the invention, the vibration attenuation piece is connected with the power supply module of the driving module, the vibration conducted to the power supply module by the driving module can be weaken
