Abstract

A spray head ( 1 ) for a water faucet ( 2 ) having a water inlet ( 3 ), and at least one first water outlet ( 4 ), one second water outlet ( 5 ) and one changeover valve ( 6 ) for selectively activating a first water-conducting connection ( 7 ) from the water inlet ( 3 ) to the first water outlet ( 4 ) or a second water-conducting connection ( 8 ) from the water inlet ( 3 ) to the second water outlet ( 5 ), wherein the changeover valve ( 6 ) is connected to a setting means ( 9 ), which has a push button ( 10 ) and which is designed such that an actuation of the push button ( 10 ) makes it possible to change from the first water-conducting connection ( 7 ) to the second water-conducting connection ( 8 ) and vice versa.

First claim

The invention claimed is:

1 . A spray head ( 1 ) for a water faucet ( 2 ) comprising:
a water inlet ( 3 ), at least one first water outlet ( 4 ), one second water outlet ( 5 ), a flow rate setting means ( 14 ), and one changeover valve ( 6 ), which is configured to selectively activate either;
a first water-conducting connection ( 7 ) from the water inlet ( 3 ) to the at least one first water outlet ( 4 ), or
a second water-conducting connection ( 8 ) from the water inlet ( 3 ) to the second water outlet ( 5 ),
wherein the changeover valve ( 6 ) is connected to a setting means ( 9 ), which comprises a push button ( 10 ) and which is designed such that an actuation of the push button ( 10 ) makes it possible to change from the first water-conducting connection ( 7 ) to the second water-conducting connection ( 8 ) and vice versa, and wherein the flow rate setting means ( 14 ) is configured to adjust a flow rate of water through a water-conducting connection ( 7 , 8 ) from the water inlet ( 3 ) to a water outlet ( 4 , 5 ) of the spray head ( 1 ).

2 . The spray head ( 1 ) according to claim 1 , comprising at least one further water outlet ( 11 ), wherein the changeover valve ( 6 ) is additionally configured to activate a further water-conducting connection ( 12 ) from the water inlet ( 3 ) to the further water outlet ( 11 ), wherein by actuating the push button ( 10 ) it is possible to change to the further water-conducting connection ( 12 ), wherein by repeated actuation of the push button ( 10 ) it is possible to cycle through all water-conducting connections ( 7 , 8 , 12 ).

3 . The spray head ( 1 ) according to claim 1 , wherein each water outlet ( 4 , 5 ) has assigned a spray pattern ( 13 ) so that the spray pattern ( 13 ) can be selected by actuating the push button ( 10 ).

4 . The spray head ( 1 ) according to claim 1 , wherein the flow rate setting means ( 14 ) is configured to infinitely adjust a flow rate.

5 . The spray head ( 1 ) according to claim 1 , wherein the changeover valve ( 6 ) has a valve body ( 15 ) and a valve chamber ( 16 ), in which the valve body ( 15 ) is moveably arranged and the first water-conducting connection ( 7 ) and the second water-conducting connection ( 8 ) extend through the valve chamber ( 16 ), wherein
the first water-conducting connection ( 7 ) is opened and the second water-conducting connection ( 8 ) is closed when the valve body ( 15 ) is in a first position ( 17 ) in the valve chamber ( 16 ) and the second water-conducting connection ( 8 ) is opened and the first water-conducting connection ( 7 ) is closed when the valve body ( 15 ) is in a second position ( 18 ) in the valve chamber ( 16 ), wherein
the first position ( 17 ) and the second position ( 18 ) are spaced apart from each other along an axis ( 19 ) of the valve chamber ( 16 ) and/or at a rotation angle ( 20 ) of the valve body ( 15 ) in the valve chamber ( 16 ) and by actuating the push button ( 10 ) the valve body ( 15 ) is moved from the first position ( 17 ) to the second position ( 18 ) and vice versa.

6 . The spray head ( 1 ) according to claim 5 , wherein a snap mechanism ( 21 ) is formed in the valve chamber ( 16 ) for the valve body ( 15 ), which snap mechanism can be used to hold the valve body ( 15 ) either in the first position ( 17 ) or in the second position ( 18 ).

7 . The spray head ( 1 ) according to claim 6 , wherein the snap mechanism ( 21 ) has a spring ( 25 ), which selectively presses the valve body ( 15 ) into a snap fixture ( 26 ) in the first position ( 17 ) or in the second position ( 18 ), wherein by actuating the push button ( 10 ) an overcoming of the spring force of the spring ( 25 ) causes a movement of the valve body ( 15 ) to the other position ( 17 , 18 ), wherein, when the push button ( 10 ) is released, the spring ( 25 ) presses the valve body ( 15 ) is by to the other position ( 17 , 18 ).

8 . The spray head ( 1 ) according to claim 5 , wherein the valve body ( 15 ) has at least one circumferential O-ring seal ( 29 ), which seals against a valve chamber wall ( 23 ) of the valve chamber ( 16 ).

9 . The spray head ( 1 ) according to claim 5 , wherein at least one first water-conducting connection ( 7 ) or one second water-conducting connection ( 8 ) opens circumferentially into the valve chamber ( 16 ).

10 . The spray head ( 1 ) according to claim 5 , wherein at least one first water-conducting connection ( 7 ) or a second water-conducting connection ( 8 ) opens on the end face into the valve chamber ( 16 ).

11 . A spray head ( 1 ) for a water faucet ( 2 ) comprising:
a water inlet ( 3 ), at least one first water outlet ( 4 ), one second water outlet ( 5 ), at least one further water outlet ( 11 ), and one changeover valve ( 6 ), which is configured to selectively activate either:
a first water-conducting connection ( 7 ) from the water inlet ( 3 ) to the at least one first water outlet ( 4 ), or
a second water-conducting connection ( 8 ) from the water inlet ( 3 ) to the second water outlet ( 5 ), or
a further water-conducting connection ( 12 ) from the water inlet ( 3 ) to the further water outlet ( 11 ),
wherein the changeover valve ( 6 ) is connected to a setting means ( 9 ), which comprises a push button ( 10 ) and which is designed such that an actuation of the push button ( 10 ) makes it possible to cycle through the first water-conducting connection ( 7 ), the second water-conducting connection ( 8 ), and the further water-conducting connection ( 12 ).

12 . The spray head ( 1 ) according to claim 11 , wherein each water outlet ( 4 , 5 , 11 ) has assigned a spray pattern ( 13 ) so that the spray pattern ( 13 ) can be selected by actuating the push button ( 10 ).

13 . The spray head ( 1 ) according to claim 11 , further comprising a flow rate setting means ( 14 ) configured to adjust a flow rate of water through a water-conducting connection ( 7 , 8 , 12 ) from the water inlet ( 3 ) to a water outlet ( 4 , 5 , 11 ) of the spray head ( 1 ).

14 . The spray head ( 1 ) according to claim 13 , wherein the flow rate setting means ( 14 ) is configured to infinitely adjust a flow rate.

15 . The spray head ( 1 ) according to claim 11 , wherein the changeover valve ( 6 ) is configured such that only one of the water-conducting connections ( 7 , 8 , 12 ) can be open at a time and the other two water-conducting connections ( 8 , 12 ), ( 7 , 12 ), or ( 7 , 8 ) are then closed.
