Abstract

A spray head is provided that includes a housing having a water inlet, at least one water guide, and a housing bottom, in which jet outlet openings are arranged, wherein the water guide is used as a connection between the water inlet and a number of jet outlet openings and a valve element for sealing a valve opening is provided for the water guide. The valve element is movably mounted on both sides and a control device having at least one control element that acts on the valve element is provided, wherein the control element defines a translational movement of the valve element by a valve stroke.

First claim

What is claimed is:

1. A spray head with a housing, the spray head comprising:
a water inlet;
at least one water guide;
a housing bottom, in which jet outlet openings are arranged, the water guide being adapted as a connection between the water inlet and the jet outlet openings;
a valve element configured to seal a valve opening for the water guide, the valve element being movably mounted on both sides;
a second valve element that supplies air and is arranged in the spray head; and
a control device having at least one control element acting on the valve element, the control device defining a displacement of the valve element,
wherein in a first position of the control device, a surface of the at least one control element physically contacts a surface of the valve element to displace the valve element to open the valve opening,
wherein in a second position of the control device, the surface of the at least one control element does not physically contact the surface of the valve element, such that the valve opening remains sealed by the valve element, and
wherein the control device further includes an air control element, wherein in a third position of the control device, the air control element contacts the second valve element to displace the second valve element.

2. The spray head according to claim 1 , wherein the valve element releases or closes the valve opening completely or partially depending on a position of the at least one control element.

3. The spray head according to claim 1 , wherein the valve element, in a closed position, is acted on by water pressure and/or a spring element.

4. The spray head according to claim 1 , wherein the valve element is controllable individually or in combination with the second valve element.

5. The spray head according to claim 1 , wherein the at least one control element is a cam, a pin, a rocker lever, or a recess.

6. The spray head according to claim 1 , wherein the at least one control element is arranged on the control device for a plurality of valve elements.

7. The spray head according to claim 1 , wherein, per valve element, more than one control element is provided on the control device.

8. The spray head according to claim 1 , wherein the at least one control element has bevels or geometric curved tracks for a continuous adjustment of the displacement of the valve element.

9. The spray head according to claim 1 , wherein a disk is provided and the at least one control element protrudes from a surface of the disk so as to be arranged substantially perpendicular to a disk plane, wherein the disk and the at least one control element are provided as the control device.

10. The spray head according to claim 9 , wherein the disk is rotatable about an axis arranged substantially perpendicular to the housing bottom or parallel to the valve element axis.

11. The spray head according to claim 1 , wherein a disk movable in a translational manner is provided as the control device.

12. The spray head according to claim 1 , wherein a circular ring or a cylindrical element with radially arranged cams is provided as the control device.

13. The spray head according to claim 1 , wherein a camshaft is provided as the control device.

14. The spray head according to claim 1 , wherein in the third position of the control device, one of the at least one control elements contacts the first valve element, such that both the first valve element and the second valve element are displaced.

15. The spray head according to claim 1 , wherein the at least one control element moves in a different direction than the valve element.

16. A spray head with a housing, the spray head comprising:
a water inlet;
a spray plate in which jet outlet openings are arranged;
a first valve opening that supplies water to the jet outlet openings;
a first valve element configured to move between open and closed positions so as to open the first valve opening and seal the first valve opening;
a second valve opening that supplies air and a second valve element configured to move between open and closed positions so as to open the second valve opening and seal the second valve opening, and
a control device having at least one first control element provided thereon,
wherein in a first position of the control device, a surface of the at least one first control element physically contacts and pushes a surface of the first valve element to the open position so as to open the first valve opening,
wherein in a second position of the control device, the surface of the at least one first control element is positioned apart from the surface of the first valve element, such that the first valve element is in the closed position so as to seal the first valve opening,
wherein the control device further includes a second control element associated with the second valve element, and
wherein in a third position of the control device, the second control element contacts and pushes the second valve element to the open position so as to open the second valve opening.

17. The spray head according to claim 16 , wherein the at least one first control element moves in a different direction than the valve element.

18. The spray head according to claim 16 , wherein in the third position of the control device, one of the at least one first control elements contacts the first valve element, such that both the first valve element and the second valve element are contacted and pushed into the open position.

19. The spray head according to claim 1 , wherein the at least one control element and the air control element protrude from a same surface of the control device.

20. The spray head according to claim 16 , wherein the at least one first control element and the second control element protrude from a same surface of the control device.

21. The spray head according to claim 16 , wherein a disk is provided and the at least one first control element protrudes from a surface of the disk so as to be arranged substantially perpendicular to a disk plane, wherein the disk and the at least one first control element are provided as the control device.

22. A spray head with a housing, the spray head comprising:
a water inlet;
at least one water guide;
a housing bottom, in which jet outlet openings are arranged, the water guide being adapted as a connection between the water inlet and the jet outlet openings;
a valve element configured to seal a valve opening for the water guide, the valve element being movably mounted on both sides;
a second valve element that supplies air and is arranged in the spray head; and
a rotatable control device having at least one control element fixed thereon that acts on the valve element, a rotational movement of the control device defining a linear displacement of the valve element,
wherein, during rotation of the rotatable control device, the at least one control element fixed thereon is rotated from a first position in which the at least one control element displaces the valve element to open the valve opening to a second position in which the at least one control element does not displace the valve element, such that the valve opening remains sealed by the valve element, and
wherein the control device further includes an air control element, wherein in a third position of the control device, the air control element contacts the second valve element to displace the second valve element.

23. The spray head according to claim 22 , wherei
