Abstract

A shower head contains a shower head core with a connection to a water main and a cup-shaped jacket surrounding the core. The jacket only frees the jet disk connected to the core. For switching between two groups of jet exit openings a switching element is provided, which is rotatably located in the shower head core and is rotated by rotating the shower head jacket with respect to the still stationary core and jet disk.

Claims

1. Shower head having a shower head core, which has a jet disk with at least two groups of jet exit openings and in each case a water duct to each group of jet exit openings, the jet disk being fixably mounted to the shower head core, a shower head jacket, which surrounds the shower head core and is rotatably mounted with respect to the latter, as well as with a switching mechanism, which has a switching element positioned transversely to the water flow direction and rotatable with respect to the shower head core, coupled to an operating member, which is connectable to the shower head jacket.

2. Shower head according to claim 1, wherein the switching element comprises a flat disk, which engages on an end face of the shower head core having control openings.

3. Shower head according to claim 1, wherein spring action is applied beforehand to the switching element.

4. Shower head according to claim 2, wherein the disk is planar.

5. Shower head according to claim 2, wherein a circumference of the disk engages on a inner wall of a cylindrical recess.

6. Shower head according to claim 1, wherein the switching element has a lug engaging through an opening in the shower head core and which is connectable downstream of the switching element to the operating member.

7. Shower head according to claim 6, wherein the lug is located in a rotation axis of the switching element.

8. Shower head according to claim 6, wherein a seal is placed between the lug of the switching element and the opening of the shower head core.

9. Shower head according to claim 8, wherein the core comprises control openings of channels leading to the groups of jet exit openings, wherein the seal is positioned radially within the control openings.

10. Shower head according to claim 6, wherein the operating member is a radially directed lever with an opening in the vicinity of its one end and in which engages the lug of the switching element.
