    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: The present disclosure relates to an oral irrigator. In one embodiment, the oral irrigator includes a motor, a pump body, a connecting rod, and a diaphragm seal. The connecting rod is at least partially received within the pump body and is movably connected to the motor such that the motor moves the connecting rod between a first position and a second position within the pump body. The diaphragm seal is connected to the connecting rod and the pump body and deforms from a first orientation to a second orientation as the connecting rod moves from the first position to the second position.

    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 including a reservoir, a handle, and a tip connected to the handle and in fluid communication with the reservoir. The oral irrigator also includes a base unit including an operating assembly configured to selectively provide a first fluid from the reservoir to the tip. The operating may include, an some examples, a motor and a pump. The oral irrigator further includes a fluid pressure trigger connected to the handle and including a second fluid. Based on a pressure of the second fluid, the fluid pressure trigger closes an electrical contact to the operating assembly causing the operating assembly to selectively vary at least one characteristic of the first fluid flow from the reservoir to the tip.
