ORAL CARE DEVICE HAVING A PUMP-FREE FLUID DELIVERY SYSTEM

摘要

A powered oral care apparatus (2) has a pump-free fluid delivery system for delivering one or more fluids to the oral cavity of a user. The oral care apparatus may employ an oral care assembly (30) that has a capsule member (38) for delivering fluid through a number of openings (31, 46) in response to movement of a head (4) of the oral care apparatus. The oral care apparatus may also employ an oral care assembly (62) having a diaphragm member (84) and a mass member (88) coupled thereto wherein, in response to motion being imparted to the brushhead, the mass member and diaphragm member generate a pumping force to cause fluid to be delivered out of the oral care assembly.
