A dental treatment appliance includes a treatment system which transmits a pulsed signal towards the oral cavity and receives a signal returned from the oral cavity. A controller actuates the treatment of the oral cavity of the user depending on the received signal.

A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system. A motorised drive unit drives movement of a bristle carrier relative to the handle. At least part of an inlet conduit of the fluid delivery system lies adjacent to the external surface of the motor, and at least part of an outlet conduit of the fluid delivery system extends through the motor.

A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the reservoir, and for delivering working fluid from a nozzle to the oral cavity of a user. The fluid reservoir includes a fluid port from which fluid is dispensed from the fluid reservoir, and through which the fluid reservoir is replenished. The fluid reservoir is moveable between first and second positions to expose the fluid port. A stem extending between the handle and the nozzle includes a stop member for inhibiting movement of the fluid reservoir beyond the second position.

A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the reservoir, and for delivering working fluid to the oral cavity of a user. The fluid reservoir includes a fluid port from which fluid is dispensed from the fluid reservoir, and through which the fluid reservoir is replenished. The fluid reservoir is moveable along the handle between a first position in which the fluid port is connected to the fluid delivery system, and a second position in which the fluid port is exposed to allow the fluid reservoir to be replenished.

A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the reservoir, and for delivering working fluid to the oral cavity of a user. A drive unit drives movement of a bristle carrier relative to the handle. The fluid reservoir extends about at least part of the drive unit.

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. A contact member for engaging the teeth of the user is moveable relative to the nozzle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of contact member relative to the nozzle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.

A suction assembly, toothbrush, and method are provided that suction fluids and debris resulting from brushing. The suction assembly includes a housing configured to couple to the toothbrush so that a portion extends around sides and a back of the toothbrush head and is spaced from the toothbrush head by a gap. The suction assembly further includes a vacuum pump, a collection reservoir, and one or more conduits that couple the vacuum pump, suction head portion, and collection reservoir to apply a suction around the toothbrush head through the gap and deposit suctioned material in the collection reservoir.

A pump assembly for a dental cleaning appliance includes a fluid chamber, a piston, and a drive. The drive rotates a coupling member having two angularly opposed pins. An arm pivotably connected to the piston has a seat for receiving one of the pins to couple the piston to the drive. Through continued rotation of the coupling member, the piston moves within the fluid chamber to draw fluid into the fluid chamber until the second detent contacts the arm to push it away from the first detent to decouple the drive from the piston. This allows a compressed spring to actuate the piston to urge a burst of fluid from the fluid chamber.

An electric toothbrush relates to personal care products, oral care products, namely, toothbrushes. The technical problem to be solved by this technical solution is the lack of functional portable electric toothbrushes that are easy to transport and couple bristles for cleaning with a cleaning agent. Similar toothbrush currently on the market do not provide adequate hygiene, namely, cleaning agent is discharged from the bore directly through the bristles, which results in the ingress of catalase, bacteria into the internal container with cleaning agent. This technical problem is solved by achieving such a technical result as improving the quality of brushing teeth, by ensuring the hygiene of the portable electric toothbrush that couples a bristle for cleaning with a cleaning agent. The technical result is achieved due to the fact that the electric toothbrush consists of a bottle body containing the cleaning agent, a neck with a bristle attachment, a push dispenser for feeding the cleaning agent, while the bottle body and the neck with the bristle attachment are connected by a fixing device and move in the longitudinal plane relative to each other, wherein the neck housing comprises an insert-type electric actuator tightly fixed therein, a compartment for at least one battery, an insulating cover of the compartment, and a button for activating the device, wherein the bristle attachment performs a vibration movement, and wherein the spout outlet of the pressure head does not come into contact with the bristle attachment when in the folded position.

An oral care implement for dispensing an oral care agent includes a housing, reservoir therein containing an oral care fluid, and an electrical circuit comprising first and second electrodes connected to an onboard power source. Each electrode is in contact with the oral care fluid in the housing. An actuator, operably coupled to the power source, is configured to both selectively energize the circuit and activate dispensing of the oral care fluid. An electrical charge is applied to the oral care fluid by activating the actuator when dispensing the oral care fluid. When the fluid comprises a peroxide based tooth whitening agent, the dispensed fluid pH is increased by the electrical charge which improves the efficacy of the whitener. In one embodiment, the implement is a modular system including a powered base unit and one or more interchangeable cartridges each having a reservoir containing an oral care fluid.
