Problems solved by technology

[0002] Existing electric toothbrushes, the brush head is either a rotating brush head, and the bristles rotate forward and backward around the toothbrush handle. Although it can effectively remove the dirt on the surface of the teeth, it is difficult to remove the dirt in the gaps between the teeth, and its trajectory is an arc. , does not meet the recommended vertical tooth brushing method along the tooth growth direction; or it is a swinging brush head, the bristles swing back and forth perpendicular to the direction of the toothbrush handle, which can effectively remove the dirt in the teeth, but it needs to be fully cleaned. It takes more time and the efficiency of brushing teeth is not high
