  • Patent number: 11432847
    Abstract: A personal care appliance includes a housing, a drive assembly provided in the housing, and a workpiece member. The drive assembly includes a stator and an armature adjacent the stator, wherein the stator, when energized, is structured to cause the armature to oscillate back and forth. The personal care appliance further includes a mounting assembly having a pivot arm having a shaft member and first and second mounting members. The workpiece member is coupled to the first end portion of the shaft member such that oscillation of the armature causes the workpiece member to oscillate relative to the housing.
    Type: Grant

  • Patent number: 11266228
    Abstract: A makeup brush includes a housing having a longitudinal axis, and a drive assembly provided within the housing. The drive assembly includes a stator assembly and an armature assembly adjacent the stator assembly, the armature assembly including a mounting member held by the housing and a pivot arm member pivotably coupled to the mounting member, the pivot arm member being structured to pivot with respect to the mounting member about an axis that is parallel to the longitudinal axis, wherein the stator, when energized, is structured to cause the pivot arm member to pivot with respect to the mounting member. The makeup brush also includes a brush head member having a plurality of bristles and being coupled to the pivot arm member such that pivoting movement of the pivot member causes the brush head member to oscillate relative to the housing.
