<p>A hydraulic pressure driven toothbrush includes a hollow handle (1), a brush head (2) with brush bristles (3), a hydraulic pressure driven mechanism (4) in the handle (1), a transmission mechanism connecting the hydraulic pressure driven mechanism (4) to the brush bristles (3). The transmission mechanism includes an eccentric rotating assembly (5) which is provided under the brush bristles (3), and links with the hydraulic pressure driven mechanism (4), thereby driving the brush bristles (3) to move in up-down and left-right directions.</p> |
