Title:
ELECTRIC MASSAGER AND PWM-BASED SKELETON IDENTIFICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/217995
Kind Code:
A1
Abstract:
An electric massager and a PWM-based skeleton identification method therefor, the method comprising: acquiring a no-load PWM pulse width value of an electric motor at the current gear when an electric massager is not in contact with a human body (S1); collecting a real-time PWM pulse width value of the electric motor of the electric massager according to a preset period (S2); and according to the real-time PWM pulse width value and the no-load PWM pulse width value, determining whether the part being currently massaged is a skeleton (S3). By means of the skeleton identification method, production and assembly difficulties and costs are reduced, the service life of an electric massager is prolonged, and the accuracy of skeleton identification is improved. The method is particularly applicable to a fascia gun.
