Abstract: An oral irrigator may include a body, a reservoir connected to the body, a tip connected to the body, a motor positioned within the body and including a drive shaft, a pinion gear connected to the drive shaft, a driven gear engaged with the pinion gear, a pump body positioned within the body and defining a pump chamber for receiving fluid from the reservoir, a piston positioned within the pump body, wherein the piston slidably engages an interior surface of the pump body to form a fluid-tight seal, and a connecting rod including a first end connected to the piston, a second end eccentrically connected to the driven gear, and a shaft extending from the first end to the second end. The shaft includes a first rib and a second rib spaced apart from the first rib along a length of the shaft.

Abstract: An oral irrigator has a base unit housing a motor and a pump, a removable reservoir defining a reservoir cavity configured to mechanically couple to a top surface of the base unit and fluidly couple the reservoir cavity to the pump, and a belt drive assembly connecting the motor to the pump. The belt drive assembly includes a drive pulley connected to an output shaft of the motor, a driven pulley spaced apart from the drive pulley and mechanically connected to a piston that drives the pump, and a continuous belt connecting the drive pulley to the driven pulley. A handle for the oral irrigator may include a housing defining a slot formed in an outer wall of the housing.

Abstract: An oral irrigator has a removable reservoir defining a reservoir cavity, a base unit housing a motor and a pump, and a handle for directing fluid flow from the pump removably connected to the base unit and fluidly coupled to the pump by a hose. The handle has a housing defining a slot formed in an outer wall of the housing. The slot is bounded by two opposing walls spaced apart from each other and a transverse wall at a terminal interior end of the opposing walls. The outer wall of the housing is open to the slot at lateral sides of the two opposing walls and at a base end of the opposing walls opposite the transverse wall.

Abstract: In one embodiment, an oral irrigator including a reservoir, a tip fluidly connected to the reservoir, a motor having a drive shaft, and a pump. The pump includes a pump body including a pump inlet fluidly connected to the reservoir and a pump outlet fluidly connected to the tip, a spiral pinion gear including a plurality of pinion gear teeth that curve along their length, and a spiral driven gear including a plurality of driven gear teeth that mesh with the pinion gear teeth. The pump also may include a connecting rod eccentrically connected to the driven gear and a piston and received within the pump body. Movement of the drive shaft causes the pinion gear to rotate, causing the driven gear to rotate, translating the connecting rod and moving the piston laterally within the pump body to pull fluid from the reservoir and push the fluid to the tip.

Abstract: 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.
