An apparatus for dental irrigation may be provided to project fluid onto the surfaces of, and the interproximal spaces between, a user's teeth and gum-line. The apparatus may comprise two hollow U-shaped manifolds having orifices located on their interior faces used as fluid jets. The manifolds may be connected, at a central point of reflection, by a rotating inlet joint which supplies the fluid flow. When placed in the user's mouth, the apparatus may be designed to receive the top and bottom sets of teeth in each corresponding U-shaped manifold, with orifices configured to provide fluid jets aligned towards the lingual and buccal side of the teeth. The orifices may be staggered to provide staggered fluid flow. A user's teeth may be cleaned with a controlled fluid flow by moving the apparatus in a sweeping motion between each set of rear molars.

The present invention is an oral hygiene system for providing pressurized water to a person's teeth or gums for oral hygiene. The oral hygiene system includes a main valve assembly, a filter assembly, a pressure tank assembly, a syphon assembly and a waterpik assembly. The main valve assembly is connectable to a water line, and includes a valve unit for controlling water flow. The filter assembly includes a filter cartridge, and is in fluid communication with the main valve assembly. The pressure tank assembly is in fluid communication with the filter assembly. The syphon assembly is capable of storing a liquid, and can include a syphon tube capable of dispensing the liquid into the water received from the pressure tank assembly. The waterpik assembly is in fluid communication with the syphon assembly, and is capable of allowing a user to provide pressurized water to a person's teeth or gums.

A handle of an oral irrigator is provided. The handle may include a handle housing with a first segment and a second segment configured to couple together and define a cavity there between, a first set of interior walls extending from the first segment, and a second set of interior walls extending from the second segment. A wall of the first set of interior walls and a wall of the second set of interior walls may limit movement of an oral irrigator component at least partially disposed in the cavity.

A water flosser is provided that may include a body, a reservoir, a cap coupled to the body and a tip extending through an opening in the cap. The water flosser may include a latch assembly that selectively retains the tip to the body. In one embodiment, the cap, the tip and the latch assembly are all rotatable as a unit about a defined axis relative to the body. An ejector button may be provided to actuate the latch assembly. In one embodiment, the ejector button extends through an upper surface of the cap. Actuation of the latch assembly may include displacement of the ejector button in a direction that is parallel with a rotational axis of the tip. In some embodiments, the reservoir of a water flosser includes a tapering volumetric section that concentrates a volume of fluid about an inlet of a tube coupled with a pump.

A water flosser is provided that may include a base, a reservoir positioned above the base, a lid, and a handle in fluid communication with the reservoir such as by a hose. The reservoir of the water flosser may include a recess formed in a reservoir wall for receipt of a hose support structure. An input device (e.g., a power button) may be positioned adjacent an upper portion of the water flosser, such as in or adjacent the lid. Actuation of the input device may include application of a force downward toward the base. The water flosser may include a motor having a dual output shaft, with one end of the shaft being associated with a rotary encoder or other sensing device to determine an operational characteristic of the motor. The motor may be driven by a power source such as a rechargeable battery.

An oral irrigator has a first liquid container, a nozzle outlet, a pump driven by a drive to pump liquid from the liquid container to the nozzle outlet so that a liquid jet is emitted via the nozzle outlet, a first switch arranged so that the drive is powered when the first switch is actuated once and the oral irrigator is switched into an ON state, and so that powering of the drive is stopped and the oral irrigator is switched into an OFF state when the first switch is actuated once again, and a second switch arranged so that the drive is powered only while the second switch is continuously actuated by the user and powering is stopped when the second switch is released.

An oral irrigator has a separate high pressure water system and low pressure mouth rinse system to deliver two different fluids to a pick or other accessories. The water system and mouth rinse system are combined in a handle. The pick is connected to the handle. The water system has a blocking valve located in the handle and the mouth rinse system has a hand pump located in the handle. The hand pump sits next to a valve button for closing the blocking valve. When the hand pump is pressed, it presses against the valve button of the blocking valve to shut off the source of high pressure water to the pick. The pressure in the pick drops so that the hand pump can then introduce mouth rinse into the pick. When the hand pump is released, the blocking valve opens up and high pressure water returns to the pick.

The present disclosure discloses a water flosser comprises a housing, a tooth irrigation portion, a water nozzle portion, a winding mechanism, and a water pipe configured to be bent and wound. The tooth irrigation portion is disposed in the housing and comprises a water inlet and a water outlet. The water nozzle portion is in communication with the water outlet of the tooth irrigation portion.
