Abstract

The present invention discloses a motor vibration intensity control method and device, and belongs to the technical field of electric toothbrushes. The method comprises the following steps: an electric toothbrush obtains first instruction information of a user and starts according to the first instruction information; a brush head receives a load force applied by the user; a control chip collectsa current change value delta-I of a driving chip, wherein the control chip has a load threshold; a load value of the load force is obtained according to the current change value delta-I; according tothe load value and the load threshold, whether the load value meets a first preset condition is judged; and when the load value meets the first preset condition, the control chip sends adjustment signals and adjusts driving pressures of a motor according to the adjustment signals. Therefore, the motor vibration intensity control method does not require assistance of sensing devices, is high in degree of intelligence, can automatically adjust vibration intensity of the motor and protects dental enamel.

Description

technical field [0001] The invention relates to the technical field of electric toothbrushes, in particular to a method and device for controlling vibration force of a motor. Background technique [0002] The vibration intensity (or vibration amplitude, vibration intensity) of the electric toothbrush head is determined by the vibration intensity of the motor of the electric toothbrush. The adjustment of the vibration intensity is realized by changing the driving voltage of the motor or adjusting the duty cycle of the PWM driving voltage. At present, this way of adjusting the vibration intensity of the motor is mostly through the preset gears (strong vibration gear, weak vibration gear) of the electric toothbrush, and artificially select gears of different intensities to adjust. No matter how much the pressure of the brush head against the teeth is, the vibration intensity of the brush head is determined by the vibration intensity of the selected preset gear; a small part is ...
