Abstract: A magnetically driven electric toothbrush head includes a brush body, a movable board and a screw cap with a cavity. A fixed frame is arranged in the cavity. Two spaced twisting plates are connected between the fixed frame and the movable board. The movable board is connected with a driving shaft extending through the fixed frame and the elastic cover is fixedly connected with the brush body. The bottom of the movable board is provided with permanent magnets. When the screw cap is connected to the brush handle, under the magnetic effect between the electromagnet and the permanent magnets and the distortion restriction of the twisting plates, the movable board drives the driving shaft and the brush body to rotate reciprocatingly and synchronously. The lower part of the twisting plate is exposed to form a twisting section which is connected to the driving shaft via a rubber strip.
