Abstract
A showerhead is described, the showerhead comprising: a top plate, comprising at least one water inlet; a bottom plate, comprising a plurality of holes through which the water is delivered; a membrane, comprising a disc of predefined thickness and a plurality of nozzles extending perpendicularly from the disc and inserted inside the holes of the bottom plate. The showerhead is characterized in that the membrane comprises a peripheral portion with thickness greater than the thickness of the disk, suitable for defining a water flow passage from the inlet to the plurality of nozzles between the top plate and the disc, and in that the peripheral portion includes a flexible tongue extending into the water flow passage and forming a seal against the top plate.

A showerhead, comprising:
- a top plate including at least one water inlet;
- a bottom plate including a plurality of holes through which the water is delivered;
- a membrane including a disc of a predefined thickness;
- and
- a plurality of nozzles extending from the disc and inserted inside the holes of the bottom plate;
- wherein:
- the membrane includes a peripheral portion with a thickness greater than the predefined thickness of the disc suitable for defining a water flow passage from the inlet to the plurality of nozzles between the top plate and the disc;
- the peripheral portion includes a flexible tongue extending into the water flow passage and forming a seal against the top plate;
- the flexible tongue includes a tip in contact with the top plate, and a first surface between the tip and the disc configured to remain in contact with the water, during delivery, to compress the tip against the top plate;
- the first surface of the tongue includes a curved portion connected to the disc;
- the curved portion of the first surface of the tongue is concave;
- and
- the first surface includes a second convex curved portion at the tip of the tongue.
A membrane for a showerhead, the membrane comprising:
- a disc of predefined thickness;
- and
- a plurality of nozzles extending perpendicularly from the disc;
- a peripheral portion with a thickness greater than the thickness of the disc, suitable for defining a water flow passage from an inlet of the showerhead to the plurality of nozzles between a top plate of the showerhead and the disc;
- wherein:
- the peripheral portion includes a flexible tongue extending radially from the peripheral portion inwards and upwards;
- the flexible tongue includes a tip, and a first surface between the tip and the disc;
- the first surface of the tongue includes a curved portion connected to the disc;
- the curved portion of the first surface of the tongue is concave;
- and
- the first surface includes a second convex curved portion at the tip of the tongue.
