the present embodiment also provides a toothbrush head 10, which toothbrush head 10 can be used in the floating power toothbrush 100 of any of the above embodiments.

Referring to figures 7 and 8, a toothbrush head 10 of the present application will now be described. The toothbrush head 10 includes a head 11 and a handle 12, the head 11 being mounted on the handle 12, the head 11 being supported by the handle 12. The brush head 11 includes a brush holder 111 and a floating brush 112, the brush holder 12 is connected to the brush holder 111, and the brush holder 111 supports the floating brush 112. The floating brush 112 is rotatably installed on the brush holder 111 so that the floating brush 112 can rotate on the brush holder 111. The floating brush 112 includes first bristles 1122 and a floating brush holder 1121, and the first bristles 1122 are mounted on the floating brush holder 1121 to support the first bristles 1122 through the floating brush holder 1121. The floating brush holder 1121 is rotatably mounted on the brush holder 111 by a pivot 113, so that the floating brush holder 1121 can rotate in the brush holder 111 to drive the first bristles 1122 to rotate on the floating brush holder 1121, and thus the first bristles 1122 can better fit the surface of teeth during brushing teeth. The axis 1131 of the pivot 113 is inclined or deviated from the central plane 120 of the brush handle 12 in the width direction, i.e. the axis 1131 of the pivot 113 is not located on the central plane 120 of the brush handle 12 in the width direction, so that when the brush handle 12 oscillates, the pivot 113 is pushed to oscillate, and the floating brush base 1121 and the first bristles 1122 are driven to oscillate for cleaning.
