Abstract
The invention is directed to an interproximal brush for an electric toothbrush which is coupled to the shaft driving the bristle supporting structure in an alternating motion in a manner independent of the coupling of the bristle supporting structure to the shaft. The interproximal brush performs a pivotal motion enabling additional cleaning in particular of interproximal spaces.
Claims27
An electric toothbrush comprising:
- a brush section and a rotatably carried shaft received in said brush section, said brush section including a bristle supporting structure coupled to the shaft for motion about an axis perpendicular to an axis of rotation of the shaft, and
- an interproximal brush coupled to the shaft for motion about the axis of rotation of the shaft, wherein the coupling of the interproximal brush to the shaft is configured such that the motion of the interproximal brush follows an arc of rotation.
An electric toothbrush comprising:
- a brush section and a rotatably carried shaft received in said brush section, said brush section including a bristle supporting structure coupled to the shaft for motion about an axis perpendicular to an axis of rotation of the shaft, and
- an interproximal brush fixedly and directly secured to the shaft.
An electric toothbrush comprising:
- a brush section and a rotatably carried shaft received in said brush section, said brush section including a bristle supporting structure coupled to the shaft for motion about an axis perpendicular to an axis of rotation of the shaft, and
- an interproximal brush coupled to the shaft for motion about the axis of rotation of the shaft, said interproximal brush including a mount in which at least one bristle cluster is held, said mount being fixedly connected to the shaft.
