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.
Claims23
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.
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.
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.
