A device for directing a liquid onto a plurality of surfaces of the oral cavity, the device including a handle, a neck, and a head, where the head includes a cleaning component including a chamber for maintaining the liquid proximate the surfaces, where the chamber is defined by front and rear sealing membranes, inner side walls and a base inner wall, and where the inner side walls each include a plurality of openings, the device further including a first manifold and a second manifold, a first port and a second port for conveying liquid; and means for providing an effective seal of the device within the oral cavity.

An oral care device suitable for use in providing a beneficial effect to an oral cavity of a mammal, which device includes means for providing reciprocation of a liquid effective for providing the beneficial effect of the oral cavity when the liquid is contacted with a plurality of surfaces thereof under conditions effective to provide the beneficial effect.

The present disclosure relates to a tooth cleaning device having an internal fluid conduit 58 formed therein, and the tooth cleaning device includes: a main body 10 which has a tube T1 provided in the main body 10 and selectively connectable with a drive unit 100; and a cleaning body 50 which is assembled to one side of the main body 10, and has the internal fluid conduit 58 formed in the cleaning body 50 and connectable with the tube T1, in which at least one nozzle 65 is formed to be opened at one end of the internal fluid conduit 58. Further, when the main body 10 and the cleaning body 50 are assembled, one end of the tube T1 is connected to one end of the internal fluid conduit 58 so as to form a single continuous flow path, and through the single continuous flow path, a cleaning solution may be discharged or a fluid is sucked and then discharged to the outside. According to the present disclosure as described above, the main body 10 and the cleaning body 50, which constitute the tooth cleaning device, may be assembled and disassembled, and as a result, it is possible to repair, replace, or wash some components such as the tube T1 and the internal fluid conduit 58 by disassembling the components.

An oral irrigator includes a flexible inlet water tube that may be passed through a magnet assembly to treat the water as it passes through the tube. The magnet assembly may include a number of discs including a magnetic material which are separated by spacers of a non-magnetic material such as a plastic. The magnets and separators may have an aperture in the center to accommodate the inlet water tube. The oral irrigator may include a tip that provides a thread-like stream of water. The pressure of this stream may be due in part to the internal structure of the irrigator tip in which the diameter of an internal water channel gradual narrows until it reaches and is ejected from an orifice at a distal end of the tip. The oral irrigator may receive water from a water tank or a direct connection to a house water supply.

An oral irrigator including a reservoir, a handle in fluid communication with the reservoir, a base in fluid communication with the handle and the reservoir, and a valve assembly. The valve assembly is configured to couple the handle to the base. In a first configuration, the handle valve and base valve are closed to prevent fluid flow out of the handle and the base, respectively, and in a second configuration, the handle valve and the base valve are open to allow fluid to flow between the base and the handle.
