Pump for dental water jet
First Claim
Patent Images
1. A dental water jet device pump comprising:
- a pump chassis;
an end plate adjustably connected to the pump chassis;
a first alignment shaft;
a first gear configured to rotate around a longitudinal axis of the first alignment shaft;
a second alignment shaft rotatably mounted to the end plate; and
a second gear engaging the first gear and configured to rotate around a longitudinal axis of the second alignment shaft;
whereinselectively adjusting the end plate relative to the pump chassis selectively adjusts the location of the longitudinal axis of the second alignment shaft relative to the longitudinal axis of the first alignment shaft from a first position to a second position.

Abstract
A pump for an oral irrigator includes a pump chassis, an eccentric end plate movably connected to the pump chassis, a first alignment shaft connected to the pump chassis, a second alignment shaft connected to the eccentric end plate, a first gear rotating around a longitudinal axis of the first alignment shaft, and a second gear engaging the first gear and rotating around a longitudinal axis of the second alignment shaft. By selectively moving the eccentric end plate relative to the pump chassis selectively moves the second gear relative to the first gear.

11. A pump for an oral irrigator comprising:
-
a pump chassis; a stator supported by the pump chassis; a rotor magnetically connected to the stator, wherein when power is supplied to the stator, the stator causes the rotor to rotate; a first alignment shaft connected to the rotor; a first gear operatively connected to the first alignment shaft, wherein when the rotor rotates the first gear rotates; a second gear operatively connected to the first gear, wherein when the first gear rotates, the second gear rotates; a second alignment shaft operatively connected to the second gear; an alignment plate operatively connected to the pump chassis and operatively connected to the second alignment shaft;
wherein selectively moving the alignment plate adjusts the location of a longitudinal axis of the second alignment shaft relative to a longitudinal axis of the first alignment shaft from a first position to a second position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
