1. An oral irrigator pump comprising:
- a motor;
a pump body;
a connecting rod at least partially received within the pump body and movably connected to the motor, wherein the motor moves the connecting rod between a first position and a second position within the pump body; and
a diaphragm seal sealing connected to the connecting rod and to the pump body, wherein the diaphragm seal deforms from a first orientation to a second orientation as the connecting rod moves from the first position to the second position.

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.

8. An oral irrigator comprising:
-
a reservoir; a tip fluidly connected to the reservoir; a motor having a drive shaft; a pump fluidly connected to the reservoir and the tip, the pump comprising a pump body including a pump inlet fluidly connected to the reservoir and a pump outlet fluidly connected to the tip; a pinion gear placed on the drive shaft and including a plurality of pinion gear teeth that curve along their length; a driven gear including a plurality of driven gear teeth that mesh with the pinion gear teeth, wherein the pinion gear teeth and the driven gear teeth are spiral gears with beveled edges; a connecting rod eccentrically connected to the driven gear; and a piston connected to a first end of the connecting rod and received within the pump body, wherein movement of the drive shaft of the motor causes the pinion gear to rotate, which causes 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.

9. An oral irrigator comprising:
-
a handle fluidly connected to a reservoir; and a tip latch assembly connected to the handle comprising a latch with an integrally formed biasing structure and at least one prong selectively movable from an engaged position to a disengaged position; and a tip release button engaging at least one surface of the latch;
whereina force on the tip release button causes the tip release button to exert a force against the at least one surface of the latch, overcoming a biasing force exerted by the biasing structure and causing the at least one prong to move from the engaged position to the disengaged position; and when the force is removed from the tip release button, the biasing structure exerts the biasing force on the tip release button as the at least one prong moves from the disengaged position back to the engaged position. - View Dependent Claims (10, 11)
