Abstract

A showerhead is disclosed including a first nozzle, a second nozzle, and a massage mode assembly in fluid communication with a fluid inlet, the first nozzle and the second nozzle. The massage mode assembly includes a turbine, a cam coupled to the turbine defining a dwell edge that extends between a leading corner and a follower corner, and a shutter movably coupled to the cam, where movement of the turbine causes the cam to drive shutter between a first position covering the first nozzle and opening the second nozzle and a second position opening the first nozzle and covering the second nozzle.

First claim

What is claimed is:

1. A showerhead comprising:
a first nozzle;
a second nozzle; and
a massage mode assembly in fluid communication with a fluid inlet, the first nozzle, and the second nozzle, the massage mode assembly comprising:
a turbine;
a cam coupled to the turbine defining a dwell edge that extends between a leading corner and a follower corner; and
a shutter movably coupled to the cam, wherein movement of the turbine causes the cam to drive the shutter between a first position covering the first nozzle and opening the second nozzle and a second position opening the first nozzle and covering the second nozzle.

2. The showerhead of claim 1 , wherein a length of the dwell edge determines a time period that the shutter remains in the first position and the second position.

3. The showerhead of claim 1 , wherein the cam further comprises a leading edge extending from a first side of the leading corner, wherein the dwell edge extends from a second side of the leading corner, wherein to transition from the first position to the second position the leading edge engages the shutter to initiate movement from the first position to the second position and the leading corner completes the movement from the first position to the second position.

4. The showerhead of claim 3 , wherein the dwell edge maintains the shutter in the first position until the leading edge initiates movement to the second position.

5. The showerhead of claim 3 , wherein the dwell edge and the leading edge have a convex curvature.

6. The showerhead of claim 1 , wherein the shutter comprises a cam aperture defined by an interior wall, wherein the wall comprises a first edge, a second edge perpendicular to the first edge, a third edge parallel to the first edge, and a fourth edge parallel to the second edge, wherein the cam contacts the first edge and the third edge to transition the shutter from the first position to the second position and does not contact the second edge or the fourth edge.

7. The showerhead of claim 1 , wherein the massage mode assembly further comprises a massage chamber wherein the shutter is positioned within and moves relative to the massage chamber.

8. The showerhead of claim 7 , wherein the massage chamber defines the first nozzle and the second nozzle and comprises a first curb wall and a second curb wall, wherein the first and second curb walls are parallel to one another and restrict movement of the shutter within the massage chamber.
