First Claim
1. An electric toothbrush, comprising:
- a) a main body;
b) an electric motor mounted in said main body;
c) a support member coupled to said main body, said support member having a first connection member;
d) a tuft assembly releasably attachable to said support member, said tuft assembly having a second connection member; and
, e) a transmission operatively connected to said electric motor, said transmission adapted to provide rotational motion to said tuft assembly;
wherein, one of said connection members has an elongate body with a groove on an outer surface thereof and the other of said connection members has at least one protrusion adapted to releasably engage said groove.

Abstract
The present invention is directed towards an electric toothbrush having a replaceable tuft assembly. The electric toothbrush comprises a main body, an electric motor mounted in the main body, a support member coupled to the main body, a tuft assembly which is releasably attachable to the support member and a transmission that is operatively connected to the electric motor to provide rotational motion to the tuft assembly. The support member has a first connection member and the tuft assembly has a second connection member. One of the connection members has an elongate body with a groove on its outer surface and the other connection member has at least one protrusion that is adapted to releasably engage the groove. In another aspect, the toothbrush may further comprise an adaptor that is releasably attachable to the tuft assembly.
