The invention discloses a toothbrush. The toothbrush comprises a toothbrush handle and a toothbrush head arranged on the toothbrush handle, and further comprises a spring device and an energy storageoperation part, wherein the spring device is connected with the toothbrush head through a second transmission mechanism, so that the toothbrush head is driven to move by virtue of the stored energy released from the spring device; the energy storage operation part is connected with the spring device through a first transmission mechanism, so that the spring device stores energy by virtue of the movement of the energy storage operation part. For the toothbrush, the spring is adopted as the energy storage and release part, the toothbrush belongs to the rotation toothbrush which does not need driving of a power supply, a mechanical mechanism composed of two unilateral bearings is used, while energy storage power is input to the spring, the power output to the toothbrush head by the spring cannot be stopped.
