Showerhead with turbine driven shutter
View Patent ↗The present disclosure includes embodiments directed to a showerhead. In some of the embodiments, the showerhead includes a housing defining a chamber in fluid communication with a fluid inlet such as a water source, a first bank of nozzles, and a second bank of nozzles. The showerhead also includes a massage mode assembly that is at least partially received within the chamber. The massage mode assembly includes a turbine, a cam connected to or formed integrally with the turbine, and a shutter connected to the cam. With the structure of the massage mode assembly, the movement of the shutter is restricted along a single axis such that as the turbine rotates, the cam causes the shutter to alternatingly fluidly connect and disconnect the first bank of nozzles and the second bank of nozzles from the fluid inlet.
1. A showerhead comprising
a housing defining a chamber in fluid communication with a fluid inlet, a first bank of nozzles, and a second bank of nozzles; and
a massage mode assembly at least partially received within the chamber, the massage mode assembly comprising
a turbine;
a cam connected to the turbine; and
a shutter connected to the cam, wherein
movement of the shutter is restricted along a single axis; and
as the turbine rotates, the cam causes the shutter to alternatingly fluidly connect and disconnect the first bank of nozzles and the second bank of nozzles from the fluid inlet.
2. The showerhead of claim 1 , wherein
the first bank of nozzles comprises a plurality of first outlets; and
the second bank of nozzles comprises a plurality of second outlets; wherein
the first outlets are fluidly connected to the fluid inlet substantially simultaneously and are fluidly disconnected from the fluid inlet substantially simultaneously; and
the second outlets are fluidly connected to the fluid inlet substantially simultaneously and are fluidly disconnected from the fluid inlet substantially simultaneously.
3. The showerhead of claim 1 , further comprising at least one curb wall extending inward from a sidewall of the chamber, wherein the at least one curb wall interfaces with the shutter to restrict the movement of the shutter along the single axis.
4. The showerhead of claim 3 , wherein the shutter includes two curved edges and two constraining edges.
5. The showerhead of claim 4 , wherein
the at least one curb wall comprises two curb walls, and
the constraining edges of the shutter each engage a respective one of the two curb walls during movement of the shutter.
6. The showerhead of claim 1 , wherein the cam is eccentrically oriented relative to a center of the turbine.
7. The showerhead of claim 1 , wherein the cam is formed integrally with the turbine.
8. A showerhead comprising
a spray head;
an engine fluidly connected to a water source and received within the spray head, the engine comprising
a massage mode assembly comprising
a turbine; and
a shoe connected to the turbine, wherein movement of the shoe is restricted to a single axis; and
a face plate connected to the engine and configured to selectively rotate the engine, the face plate defining a plurality of nozzle apertures; wherein
fluid flow through the engine causes the turbine to rotate; and
as the turbine rotates, the shoe alternately fluidly connects and disconnects a first set of nozzle apertures and a second set of nozzle apertures from the fluid inlet.
9. The showerhead of claim 8 , wherein the massage mode assembly further comprises a cam interconnected between the turbine and the shoe.
