Abstract

The invention belongs to the technical field of electric massage equipment, discloses an electric massager and a human body contact state judgment method and a noise reduction control method thereof, and solves the problems of hardware cost increase and high production and assembly difficulty in a mode of judging whether the electric massager is in contact with a human body or not in a segmented noise reduction scheme in the traditional technology. The method comprises the following steps: comparing a real-time PWM pulse width value T of the electric massager with a PWM pulse width value Tn of the electric massager in a no-load state when the electric massager runs at a set gear rotating speed under the same gear; if the absolute value of the difference value of T and Tn is between N1 and N2, determining that the electric massager does not make contact with the human body at present, and reducing the rotating speed of the motor to the idling operation state by adjusting the PWM pulse width value; in the idling state, if it is detected that the rotating speed of the motor is continuously reduced by a certain rotating speed, determining that the electric massager makes contact with the human body, and then restoring the rotating speed of the motor to the set gear rotating speed by adjusting the PWM pulse width. The judgment method and the noise reduction control method are suitable for various electric massagers such as fascia guns.

Description

technical field [0001] The invention belongs to the technical field of electric massage equipment, and in particular relates to an electric massager, a method for judging its contact state with a human body, and a noise reduction control method. Background technique [0002] The electric massager is mainly composed of a battery, a motor and a control circuit board. The motor is driven by the eccentric wheel to drive the massage head to do reciprocating motion to achieve the massage effect of hitting back and forth on the human body. The control circuit board is provided with buttons for controlling different gears, and the motor has different speeds corresponding to different gears; after adjusting the gear, the motor keeps moving at the speed of the gear, that is, whether it touches the human body or not, the motor Keep the speed movement of this gear all the time. [0003] Since the motor will generate noise during motion, and the higher the speed, the greater the noise,...
