Embodiment 1

[0021] Such as figure 1 Shown, a kind of moving toothbrush comprises, handle and brush head, described handle interior is provided with and is used for driving the motor of described brush head, battery, and PCB board, and described PCB board comprises MCU control module and with described MCU control The motor drive module, the charging module and the regulating module are electrically connected to the module.

[0022] Among others, the circuits provided are based on sine wave or PWM driven circuits. The shown MCU control module is a single-chip microcomputer or other controllers, preferably an MCU controller.

[0023] The handle is also provided with a display light for displaying gear position and / or mode; the PCB board also includes a display module electrically connected with the MCU control module.

[0024] The handle is provided with a button, and the adjustment module is a button adjustment module. By pressing the button, the duty cycle of the motor driving module is...

Embodiment 2

[0027] Embodiment 2: As described in Embodiment 1, in this embodiment, the frequency of the motor can be replaced by adjusting the duty cycle of the motor. Adjust the vibration intensity of the motor by adjusting the frequency of the motor, so as to achieve the effect of adjusting the vibration intensity of the brush head.

Embodiment 3

[0028] Embodiment 3: As described in Embodiment 1, in this embodiment, the button in Embodiment 1 is replaced with a knob. Continuously adjust the duty cycle and frequency of the motor through the knob to adjust the vibration intensity of the motor, or adjust the resistance of the sliding rheostat through the knob to adjust the vibration intensity of the motor, or adjust the capacitance through the knob Thereby adjusting the vibration intensity of the motor.

[0029] Embodiment three has the following advantages compared with embodiment one and embodiment two:

[0030] The adjustment of the vibration intensity of the motor in Embodiment 1 and Embodiment 2 is discontinuous, while Embodiment 3 can realize the adjustment of all the intensity values ​​within the set intensity range. The user experience is better.

Abstract

The invention discloses an electric toothbrush, comprising a handle and a head. A motor to drive the head, a battery and a PCB (printed circuit board) are arranged in the handle; the PCB comprises anMCU (microcontroller unit) control module, and a motor driving module, a charging module and an adjusting module which are electrically connected with the MCU control module. The electric toothbrush has adjustable head vibrational strength, so that diverse user experience is greatly improved, and product uniformity is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric toothbrushes. Background technique [0002] Most of the toothbrush heads of electric toothbrushes in the prior art are driven by the electric motor inside the handle. The vibration intensity of the motor of the existing electric toothbrush that drives the vibration intensity of the toothbrush head by the motor is mostly not adjustable. The vibration intensity of the toothbrush head of this electric toothbrush in the prior art is single, which not only cannot meet the diversified needs of users, but also is not conducive to the control of the consistency of the vibration intensity of the brush head during mass production. Contents of the invention [0003] In view of the above technical problems, the present invention provides a motor with adjustable vibration intensity to solve the above problems. The specific plan is as follows: [0004] A kind of moving toothbrush, comprises, handle and br...
