POWERED ORAL CARE IMPLEMENT
First Claim
1. A powered toothbrush comprising:
- a handle;
a power source;
a head including a cavity and disposed at a distal end of the handle;
an electrically conducting element disposed in the cavity and electrically connected to the power source, wherein application of an electrical current from the power source to the electrically conducting element generates a magnetic field; and
a movable cleaning element connected to the head and movable relative to the cavity, the movable cleaning element comprising a bristle support member disposed at least partially over the cavity, a plurality of bristles extending from the bristle support member in a direction away from the cavity, and a ferromagnetic member,wherein the magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.

Abstract
A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.

7. A powered oral care implement comprising:
-
a housing including a cavity; one or more electrically conducting elements disposed in the cavity; a power source electrically connected to each of the one or more electrically conducting elements, wherein applying a current to individual of the one or more electrically conducting elements generates a field at the individual of the electrically conducting elements; and a cleaning element disposed on the housing to at least partially cover the cavity. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
