The three axes are x, y and z axes, in the initial state, the y axis is vertical and parallel to the axis of the brush holder of the electric toothbrush, the x axis is parallel to the end face of the brush head contacting with the teeth, and correspondingly, the z axis is vertical to the end face of the brush head contacting with the teeth. In the process of brushing teeth, the direction of the gravity acceleration is continuously changed because the electric toothbrush needs to be attached to teeth at different positions, so that the posture detection device can generate a real-time posture detection signal to reflect the posture of the electric toothbrush. In the embodiment of the invention, the low-cost three-axis motion sensor is selected as the attitude detection device, so that the overall cost of the electric toothbrush is reduced on the premise of ensuring the design purpose of the invention. The controller acquires the attitude detection signal of the attitude detection device, and processes calculation analysis, statistics and the like to obtain accurate attitude information of the electric toothbrush. The controller in this embodiment may be a single chip microcomputer or other control chip capable of achieving the purpose of this embodiment, and may be selected by those skilled in the art.
Specifically, on the basis of the above embodiment, the position between the posture detection device and the housing in the embodiment of the present invention is fixed. In order to ensure that the posture detection device can accurately measure the posture of the electric toothbrush, the posture detection device and the shell are fixed into a whole, so that the posture detection device can detect the posture presented by the shell under the condition that the electric toothbrush has different angles in use, and the posture presented by the whole electric toothbrush is represented.
Specifically, electric actuator includes motor, drive circuit and rechargeable battery, is equipped with the interface that charges on the shell, and the interface that charges is connected with rechargeable battery electricity, and rechargeable battery passes through drive circuit drive motor vibration.
