The invention provides a unitary cordless dental drive apparatus in a first embodiment having a handpiece with a cantilever arm 18 extending outward and positioned to allow a dental nose cone 26 to be connected. An activating switch 20 is located at the free end of the cantilever arm 18 in a position that is convenient for manipulation by a user. In a second embodiment, a contactor 22 is mounted below the cantilever arm 18 to contact the nose cone 26 when pressed. In a third embodiment, a standard dental office foot pedal 90 is connected to a wireless transmitter 80 for sending a signal to a receiver 92 located within the handpiece 70 for activating the handpiece 70.

An oral care appliance and a method of use are disclosed. The oral care appliance includes a mouthpiece with one or more enclosed compartments between an outer surface and an inner surface of the mouthpiece. The inner surface comprises at least one flexible membrane surrounding the one or more enclosed compartments. The oral care appliance also includes a control unit configured to regulate pressure variations in the one or more enclosed compartments to deform the flexible membrane and thereby perform an oral care action.

An oral cavity washing device includes a housing, a tubular storage space formed in the housing to store a liquid, and a pump housed in the housing to discharge the liquid. The housing includes a peripheral wall section constituting at least part of a peripheral wall of the storage space and having a supply port for supplying the liquid into the storage space, and a lid disposed at one end of the storage space to be able to entirely open and close a largest opening that is larger in area than any other opening in the housing.

The charging stand for a care apparatus according to the present disclosure includes a fifth terminal connected to a first terminal, a sixth terminal aligned with the fifth terminal and electrically connected to a second terminal, a first cover having a cylindrical shape that stores the first terminal, a second cover having a cylindrical shape that stores the second terminal, a fifth cover having a cylindrical shape that stores the fifth terminal, and a sixth cover having a cylindrical shape that stores the sixth terminal. A shape of an input connecting portion formed by the fifth cover and the sixth cover is different from a shape of an output connecting portion formed by the first cover and the second cover.

The care unit according the present disclosure includes a care apparatus that includes a storage battery and a charging stand that is electrically connected to the care apparatus, and the care unit includes a first terminal, a second terminal, a third terminal, a fourth terminal, a first cover, a second cover, a third cover, and a fourth cover. When the care apparatus is held in a predetermined position of the charging stand, the third cover is not in contact with the first cover in a radial direction orthogonal to an insertion direction of the first cover, and the fourth cover is not in contact with the second cover in a radial direction orthogonal to an insertion direction of the second cover.

Disclosed is a portable teeth cleaning apparatus, which implements, through a pump in a teeth cleaner, a function of supplementing a teeth cleaning liquid from a connecting seat connected to the teeth cleaner. Therefore, it is no longer necessary to connect the teeth cleaner to a teeth cleaning liquid source through a connecting hose during teeth cleaning, and liquid leakage is avoided during liquid supplement. Further, a seating/unseating status and whether a liquid reservoir is filled up are detected automatically, and a controller controls on/off and switching of a series of valves, thereby implementing automatic liquid supplement of the teeth cleaner.

A method and apparatus which permits arbitrary, relative motions of a distal end of a toothbrush and/or flosser with respect to a handle. Said motions are selectable by a user in real time by a selection switch. The toothbrush herein includes an elongated body used as a handle, and smaller elongated member serving as the toothbrush post. A mechanism mechanically couples said handle to said toothbrush post member permitting relative translational movement of said toothbrush post with respect to said handle.

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.

Disclosed is a teeth cleaning apparatus, including a first liquid reservoir, a teeth cleaner, a connector, and a liquid conveyer. The teeth cleaner includes a teeth cleaner body and a second liquid reservoir that is fixedly connected to the teeth cleaner body and transmits a teeth cleaning liquid to the teeth cleaner body during teeth cleaning. The connector is separable from the teeth cleaner, and the liquid conveyer transmits the teeth cleaning liquid in the first liquid reservoir to the second liquid reservoir when the teeth cleaner is connected on the connector.

An oral cleaning device according to the disclosure includes a body unit including a pump configured to discharge washing liquid, a tube connected to the body unit to allow the discharged washing liquid to flow through the tube, a washing unit connected to the tube to discharge the washing liquid, a first operation part provided at the washing unit, a controller configured to control the pump in accordance with operation of the first operation part, and a communication unit configured to establish a communication connection between the first operation part and the controller.
