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.
