Spray head with covers
Embodiments of the invention provide a spray head including a housing having a facetted front face with a plurality of intersecting surfaces. The spray head can include a nozzle in each one of the plurality of intersecting surfaces. The nozzle can be positioned within a first recess of the housing so that an outer end of the nozzle does not extend past an outer surface of the housing. The nozzle can generate and dispense a fog-like mist. The spray head can include a cover that substantially prevents an orifice of the nozzle from becoming blocked with debris. The cover can be installed within a second recess of the nozzle so that the cover is substantially flush with the outer surface of the housing.
1. A spray head comprising:
a housing having a facetted front face including a plurality of intersecting surfaces;
a plurality of nozzles, one of the plurality of nozzles included in each one of the plurality of intersecting surfaces, the one of the plurality of nozzles being positioned within a first recess of the housing so that an outer end of the one of the plurality of nozzles does not extend past an outer surface of the housing, each one of the plurality of nozzles generating and dispensing a fog-like mist; and
a cover that substantially prevents a discharge orifice of each one of the plurality of nozzles from becoming blocked with debris, the cover installed within a second recess of each one of the plurality of nozzles so that the cover is substantially flush with the outer surface of the housing.
2. The spray head of claim 1 and further comprising a fogging head body with a plurality of channels, each one of the plurality of channels leading to nail one of the plurality of nozzles.
3. The spray head of claim 1 and further comprising a strainer to filter liquid entering the spray head.
4. The spray head of claim 1 wherein the housing is constructed of stainless steel and the cover is constructed of polytetrafluoroethylene.
5. The spray head of claim 1 wherein the cover is constructed of polytetrafluoroethylene and stainless steel.
6. The spray head of claim 1 wherein the cover is press-fit in the second recess to provide sealed resistance against release until a set level of water pressure is reached.
7. The spray head of claim 1 wherein each one of the plurality of nozzles includes at least one of an energizing ring, a gasket, and an o-ring.
8. The spray head of claim 7 wherein the gasket is constructed of, copper.
9. The spray head of claim 1 wherein each one of the plurality of nozzles includes a nozzle body, the nozzle body includes a first chamber, and the first chamber is positioned upstream of a swirl insert that generates the fog-like mist.
10. The spray head of claim 9 wherein each one of the plurality of nozzles includes a second chamber downstream of the swirl insert and the discharge orifice which is downstream of the second chamber.
11. The spray head of claim 1 wherein the first recess includes an undercut, tapered joining faces, and a spring positioned between the housing and the cover.
12. The spray head of claim 11 wherein the cover expands with respect to the second recess when a temperature increases and the spring allows the cover to slide down the tapered joining face.
