Problems solved by technology

[0004] However, in the above-mentioned structure, since a motor needs to be installed in the transmission rod, it is difficult to reduce the volume of the transmission rod, and the motor can only be a miniaturized, low-power motor, so it is difficult for the vibration of the toothbrush head to reach the standard required for adult toothbrushing

Abstract

The invention discloses an electric toothbrush, which comprises a handle, wherein an opening is formed in one end of the handle; a transmission rod is arranged at the opening end; the transmission rodcomprises a cavity; a pendulum bob is arranged at one end of the cavity in a rotatable manner; a first magnetic transmission wheel is integrated on the pendulum bob; the electric toothbrush further comprises a connection shaft; a second magnetic transmission wheel opposite to the first magnetic transmission wheel is arranged at one end of the connection shaft; a third magnetic transmission wheelis arranged at the other end of the rotating shaft; a motor is arranged in the handle; a fourth magnetic transmission wheel is arranged on an output shaft of the motor; and the third magnetic transmission wheel and the fourth magnetic transmission wheel are arranged in a spacing manner. The motor of the electric toothbrush is still located in the handle, so that a full space is reserved for mounting the motor; the motor is configured to be high in power, and the size of the transmission rod can be further reduced.

Description

technical field [0001] The present invention relates to the field of personal care appliances, and more specifically, relates to an electric toothbrush. Background technique [0002] Electric toothbrushes often wish to have strong vibration while reducing the volume as much as possible, and the above-mentioned vibration can be transmitted to the toothbrush head as much as possible and not transmitted to the handle part. However, in general electric toothbrushes, the vibrating motor is arranged in the handle, and the vibrating motor protrudes from the handle through a metal shaft, and the toothbrush head is inserted on the above-mentioned metal shaft, which makes it difficult to control the volume of the electric toothbrush, and is not conducive to reducing the volume to the handle. transmitted vibration. [0003] In this regard, there are also electric toothbrushes with a front motor on the market. For details, please refer to the structure disclosed in the Chinese patent a...
