Title:
MECHANISM FOR BRUSHES WITH ROTATING HEAD PARTS
Document Type and Number:
WIPO Patent Application WO/2010/007358
Kind Code:
A3
Abstract:
A brush, such as a toothbrush, has a brushing head (1) incorporating one or more rotatable brush inserts (2). The brushing head (1) and the inserts (2) both have a plurality of bristles (4, 32, 33, 34, 35) of various forms extending therefrom, the bristles of the inserts (2) being surrounded by the bristles of the brushing head (1). The inserts (2) are retained in sockets within the brushing head (1), within which they may both rotate and move translationally, preferably undergoing an orbital motion around the socket. The inserts (2) may move continuously or reciprocally. This motion of the inserts (2) is generated by manual movement of the brush, for example while brushing a user's teeth. The inserts (2) may be provided with toothed cogs (10) that engage with recesses (6) or gaps (6) between teeth arrayed around an interior of each socket. More complex gear arrangements are also envisaged. In one variant, the brush includes an electric motor (36) powering a mechanism to vibrate the brushing head (1) as a whole; however, this motor (36) still does not drive the inserts (2).
