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.

An oral irrigator is provided. The oral irrigator may include a base unit defining a recess, a reservoir supported by the base unit, a handle support attached to the base unit above the recess, an oral irrigator handle supported by the handle support, and a tube attached to the handle and in fluid communication with the reservoir and the handle such that fluid from the reservoir flows through the tube into the handle. The tube may include a coiled portion that is received in the recess defined by the base unit when the handle is supported by the handle support.

An aligner case includes a body having a floor and a sidewall and an inner cavity, the body having at least one inlet in at least one of the floor and the sidewall, and the body having at least one outlet in at least one of the floor and the sidewall, at least one door coupleable to the sidewall and transitionable between an open condition where the inner cavity is revealed, and a closed condition where the inner cavity is covered, and an actuator configured to allow transitioning of the at least one door between the open condition and the closed condition.

An oral irrigator including a base, a reservoir supported by the base, a tip coupled to the base and the reservoir, and multiple control actuators. A first control actuator is configured to selectively power the oral irrigator. Second, third, and fourth control actuators are configured to vary the fluid pressure of the oral irrigator.

An oral irrigator including a handle housing defining a cavity, a tip removably connected to the handle housing, and a tip release assembly connected to the handle housing. The tip release assembly includes a tip eject button slidably connected to the handle housing and movable between a first position and a second position and a latch connected to the handle housing and positioned within the cavity. Movement of the tip eject button from the first position to the second position moves the latch laterally across the cavity from an engage position to a disengage position.

A dental irrigator water tank and a dental irrigator are disclosed. The dental irrigator water tank is detachably attached to a side of a dental irrigator body, and the dental irrigator water tank extends below a lower surface of the dental irrigator body when the dental irrigator water tank is attached to the dental irrigator body. The dental irrigator includes the dental irrigator water tank and a dental irrigator body. The water tank of the dental irrigator reasonably uses the structure of the body of the dental irrigator, and increases a capacity of an inner cavity of the water tank. Further, the dental irrigator water tank is provided with a water pressure stabilizing unit to ensure that when the water level in the water tank changes, the dental irrigator can also ensure that the water output is uniform.

A multi-purpose molar lift oral insertion and double level panorama form designed bristle brush tilter provides a thorough oral cleaning for dental and gums. Described is a small mechanism apparatus designed to assist with brushing teeth and other oral operations, and works especially well for persons that have difficulty with brushing their teeth. The device includes a molar gap tilt lift platform set between the upper molars and the lower molars to cause a gap or space between to upper and bottom jaw. The oral insertion can be enclosed in the mouth. A pivot axle attached to a double level bristle brush can swivels on a shaft pin allowing a user to oscillate or maneuver in left or right directions and up and down with just a touch of the fingertip.

An oral irrigator includes a base, a reservoir supported by the base and including a bottom wall and a port defined in the bottom wall, and a valve received in the port. The valve is movable between a first position in which the port is open to allow fluid flow from the reservoir to the base and a second position in which the port is closed by the valve. The valve includes a body, a cap extending from a first end of the body, a flange extending from a second end of the body opposite the first end, a sealing member positioned around the body adjacent the cap, and a spring positioned around the body adjacent the flange.

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.

An oral irrigator including a reservoir, a tip in fluid communication with the reservoir, a pump in fluid communication with the tip and the reservoir, where the motor drives the pump. The oral irrigator also includes a control module electrically coupled to the motor to vary an output of the motor. During a normal mode, the control module drives the motor to output a normal pulse rate, a normal flow rate, and a normal fluid pressure as the fluid exits the tip and during a massage mode, the control module drives the motor to output a massage pulse rate, a massage flow rate, and a massage fluid pressure as the fluid exits the tip. The massage pulse rate is lower than the normal pulse rate, the massage fluid pressure is lower than the normal fluid pressure, and the massage fluid pressure is lower than the normal fluid pressure.
