An oral cleansing device including a handle, a brush head removably connected to the handle at a top end of the handle, a base unit that supports a reservoir to serve as a fluid source, a fluid tube extending from the base unit, and a fluid connector connected to the fluid tube and removably connected to the handle at a bottom end of the hand to connect the handle to the fluid source. The fluid connector includes a magnetic element configured to provide a magnetic attraction to the base unit, thereby assisting in securing the fluid connector to the base unit.

Embodiments of the present invention comprise a powered toothbrush comprising a bristle head, an outer gear, and a plurality of bristles. Both the bristle head and the outer gear may comprise a distal end, a proximal end, and a center. The distal end of the bristle head may mate with the proximal end of the outer gear. The outer gear may rotate about a first axis of rotation. The mating between the bristle head and the outer gear may cause the bristle head to orbit the first axis of rotation via one or more bristle paths while simultaneously completing one or more rotary movements about a second axis of rotation, which may move along the bristle paths with the bristle head.

A drive mechanism for electric toothbrush includes a grip housing and a pivot housing mounted within the grip housing. The pivot housing has a fixed portion, a movable portion with a free end spaced from the fixed portion, and bridge that connects the fixed and movable portions and defines a fulcrum. A motor is mounted within the pivot housing, and an eccentric weight extends from the motor with the motor operable to rotate the eccentric weight. A brush shaft is attached to the pivot housing opposite the free end. A power source is adapted to activate the motor and rotate the eccentric weight, such that the free end of the pivot housing is driven to move by the movement of the eccentric weight, the pivot housing pivots at the fulcrum, and the brush end of the brush shaft oscillates about the fulcrum.

A denture brush that includes a frame having a plurality of wall pieces disposed at an outer circumferential part of a flat plate-shaped base, and first bristle tufts are arrayed on the wall pieces, and second bristle tufts 6 are arrayed in a center region of the base, and third bristle tufts are arrayed on an outer circumferential side of the second bristle tufts. When the denture brush is not housed in a holder, the wall pieces are positioned radially along the outer circumferential part of the base so as to be horizontal with respect to the base. When the denture brush is housed in the holder, the wall pieces are supported by a wall surface of a denture-brush-housing portion of the holder, and are positioned so as to stand upright with respect to the base.

A dental cleaning appliance includes a handle and a fluid delivery system. The fluid delivery system includes a nozzle for delivering a burst of working fluid to the teeth of a user, and a moveable fluid conduit which is moveable about an axis relative to the handle. The nozzle is moveable with the fluid conduit, which is biased for movement about the axis in a direction which urges the nozzle against a user's teeth during use of the appliance.

A dental cleaning appliance includes a handle and a fluid delivery system for delivering a burst of working fluid to the teeth of a user. Part of the fluid delivery system is moveable relative to the handle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of that part of the fluid delivery system relative to the handle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.

A toothbrush including a chassis assembly, an output shaft configured to connect to a brush head and extending at least in part through a portion of the chassis assembly, a power train assembly operably connect to the output shaft, where the power train assembly oscillates the output shaft. The toothbrush also includes a fluid connector operably coupled to the chassis assembly and fluidly coupled to the output shaft via the power train assembly. The fluid connector rotates 360 degrees relative to the chassis assembly.
