Shower head
A shower head comprising a pair of plates, for dispensing and closing, directly facing each other relative to an axial direction. The shower head comprises a closing ring which is directly arranged between the plates and fixing and sealing means suitable for fixing the plate each other and for realizing a liquid tight seal, so as to sealingly delimit with the plates a fluid collecting chamber and dispense the liquid through holes of the delivery plate. The shower head is especially thin, inexpensive to manufacture and to assemble.
1. A shower head consisting of:
a dispensing plate having an array of holes for dispensing water,
a plurality of nozzles, each installed in a respective one of said holes,
a closing plate, directly facing the dispensing plate in an axial direction,
a closing ring directly arranged between said dispensing and closing plates, said ring having two opposite axial faces, each face engaging a respective one of said plates,
said dispensing plate, closing plate, and closing ring having the same outside diameter and being connected at their outer peripheries by welding or gluing so as to define a closed chamber for liquid between said plates,
wherein the axial spacing between the plates decreases from the center of the plates to their periphery, and further comprising
a fitting in said closing plate for admitting water from a water source into said chamber.
2. A shower head according to claim 1 , wherein the axial thickness of the welding or gluing is negligible with respect to the thickness of the plates and of the ring so that the overall axial thickness of the shower head is substantially equal to the sum of the axial thickness of the ring and of the plates.
3. A shower head according to claim 1 , wherein said nozzles comprise a dispensing portion projecting from the dispensing plate and a stopping portion for retaining the nozzles in their respective holes.
4. A shower head according to claim 3 , wherein said nozzles are formed integral with a membrane.
5. A shower head according to claim 1 , wherein the plates and the closing ring have an assembled thickness not greater than 4 mm.
6. A show head according to claim 1 , wherein said plates and said closing ring are interconnected only by welding.
