Abstract
An embodiment of a brush head assembly for a powered toothbrush includes a housing, a first brush head supported by the housing, and a second brush head supported by the housing. In addition, the brush head assembly includes a driveshaft positioned in the housing and coupled to the first brush head and the second brush head, the driveshaft having a longitudinal axis. A rotation of the driveshaft about a longitudinal axis is configured to pivot the first brush head and translate the second brush head relative to the housing.

A brush head assembly for a powered toothbrush, the brush head assembly comprising:
- a housing;
- a first brush head supported by the housing;
- a second brush head supported by the housing;
- and
- a driveshaft positioned in the housing and coupled to the first brush head and the second brush head, the driveshaft having a longitudinal axis, wherein a rotation of the driveshaft about a longitudinal axis is configured to pivot the first brush head and translate the second brush head relative to the housing.

- a first brush head supported by the housing;
- a second brush head supported by the housing;
- and
- a transmission assembly positioned within the housing, the transmission assembly comprising:
- a driveshaft having a longitudinal axis;
- a first cam assembly configured to convert a rotation of the driveshaft about the longitudinal axis into a pivot of the first brush head about an axis of rotation that is different from the longitudinal axis;
- and
- a second cam assembly configured to convert the rotation of the driveshaft about the longitudinal axis into an axial translation of the second brush head along the longitudinal axis.
