First Claim
Patent Images
1. A toothbrush comprising:
- a handle containing an electric drive motor and having an engagement socket for a head section;
a replaceable head section being an elongate structure having a driveable toothbrush head at one end and having a plug part which is engageable with the socket at its opposite end;
the plug part having an end surface which when the plug part is engaged with the socket faces generally in the direction of the handle, and the socket having an end surface which faces generally in the direction of the head;
wherein;
the end surface of the plug part is resiliently deformable in the handle-head direction under the influence of pressure applied longitudinally to the end surface;
one of either the end surface of the plug part or the end surface of the socket has a convexity thereon projecting along the head-handle direction, and the other has a concavity therein which receives the projection when the plug part is engaged with the socket.

Abstract
An electrically driven toothbrush having a replaceable head section with a plug part which is engageable with a socket in its handle to connect its driveable head to its motor in the handle. The head section has a resiliently deformable end surface, and there is an engaging concavity and convexity in the respective meeting end surfaces of the plug part and the socket. The concavity and convexity engage to facilitate locking together of the head and handle. A separate replaceable head section for such a toothbrush is also provided.
