Abstract

A spray nozzle ( 1 ) for a sanitary article ( 2 ), in particular for a urinal, includes a nozzle head ( 3 ) which comprises a nozzle channel ( 4 ) which extends along a center axis (M) and has a nozzle inlet ( 5 ) and a nozzle outlet ( 6 ), and a pipe section ( 7 ) which comprises an interior ( 8 ) with an inlet ( 9 ), to which a water pipe ( 10 ) is connectable, and an outlet ( 11 ). The nozzle head ( 3 ) is mounted in the interior ( 8 ), wherein the nozzle inlet ( 5 ) is accessible from the interior ( 8 ) such that flushing water is able to enter into the nozzle channel ( 4 ) from the interior ( 8 ) and the nozzle outlet ( 6 ) projects out of the interior ( 8 ), and wherein the nozzle head ( 3 ) is secured with reference to the interior ( 8 ) of the pipe section ( 7 ) by means of a securing element ( 12 ).

First claim

The invention claimed is:

1. A spray nozzle for a sanitary article, in particular for a urinal, said spray nozzle comprising:
a nozzle head which comprises a nozzle channel which extends along a center axis and has a nozzle inlet and a nozzle outlet,
a pipe section which comprises an interior with an inlet, to which a water pipe is connectable, and an outlet, and
a cover which covers the nozzle head at its front side and which is in connection with the pipe section, wherein, in the connected state, in the region of the nozzle outlet, the cover maintains an interspace through which the water is suppliable from the nozzle outlet to the sanitary article,
wherein the nozzle head is mounted in the interior,
wherein the nozzle inlet is accessible from the interior such that flushing water is able to enter into the nozzle channel from the interior and the nozzle outlet projects out of the interior,
wherein the nozzle head is secured with reference to the interior of the pipe section by means of a securing element,
wherein the securing element is a groove and tongue connection between the nozzle head and the interior;
wherein said groove and tongue connection comprises at least one part portion which, with reference to the center axis, is formed at least in part circumferential and extending along the center axis in such a manner that a rotation of the nozzle head in the fixed interior results in an axial displacement along the center axis;
wherein the nozzle head and the pipe section include alignment elements such that, in its installation position, the nozzle head is mounted in the interior so as to be non-rotatable with reference to a movement about the center axis; and
wherein said groove and tongue connection provides the alignment element.

2. The spray nozzle according to claim 1 , wherein the nozzle head is insertable into the interior by means of the outlet of the pipe section.

3. The spray nozzle according to claim 1 , wherein a spring element, which presses the nozzle head in the direction of the cover in such a manner that the position of the nozzle head inside the pipe section when viewed along the center axis is determined, is arranged between the inlet of the pipe section and the nozzle head.

4. The spray nozzle according to claim 3 , wherein the spring element is a compression spring, or wherein the spring element includes a compression spring with a front end and a rear end as well as a guide part which is in connection with the front end and a guide part which is in connection with the rear end.

5. The spray nozzle according to claim 1 , wherein the securing element is a cover which is connectable to the pipe section and projects in such a manner over the outlet that, as a result of the cover, the nozzle head is opposed by a stop with reference to a movement out of the interior.

6. The spray nozzle according to claim 5 , wherein a spring element, which presses the nozzle head in the direction of the cover in such a manner that the position of the nozzle head inside the pipe section when viewed along the center axis (M) is determined, is arranged between the inlet of the pipe section and the nozzle head.

7. The spray nozzle according to claim 6 , wherein the spring element is a compression spring, or wherein the spring element includes a compression spring with a front end and a rear end as well as a guide part which is in connection with the front end and a guide part which is in connection with the rear end.

8. The spray nozzle according claim 5 , wherein the cover comprises a guide surface, which is formed inclined at an angle with respect to the center axis and pushes the nozzle head into the interior when the cover is assembled.

9. The spray nozzle according to claim 1 , wherein on the outside the pipe section comprises orientation elements which are formed in such a manner that they allow an alignment between the pipe section and the sanitary article with reference to a rotation about the centre axis.

10. The spray nozzle according to claim 1 , wherein a seal, which seals the gap with respect to water, is arranged in the gap between the outside surface of the nozzle head and the interior.

11. The spray nozzle according to claim 1 , wherein the nozzle head is formed in one-piece.

12. The spray nozzle according to claim 1 , wherein the nozzle head is formed in multiple parts with a nozzle part with the nozzle outlet and a bearing part with the nozzle inlet, wherein the nozzle channel extends through the nozzle part and the bearing part and wherein the two parts are fixedly connected with each other.

13. The spray nozzle according to claim 1 , wherein the pipe section is connectable to a water pipe in the region of the inlet.

14. The spray nozzle according to claim 13 , wherein the nozzle head comprises a lateral surface which extends around the center axis and a front surface, wherein the nozzle inlet is arranged opposite the front surface and wherein the nozzle outlet penetrates the lateral surface in the region of the front surface.

15. The spray nozzle according to claim 14 , wherein the nozzle outlet only extends in part around the center axis and comprises an opening angle of a maximum of 180, in particular of a maximum of 160, in a particularly preferred manner of between 90 and 180.

16. The spray nozzle according to claim 14 wherein the cross section of the nozzle outlet when viewed in the direction of the center axis varies over the circumference, wherein the cross section is preferably minimal in the region of the center of the nozzle outlet.

17. The spray nozzle according to claim 14 , wherein the nozzle outlet only extends in part around the center axis and comprises an opening angle of a maximum of 180°, in particular of a maximum of 160°, in a particularly preferred manner of between 90° and 180°, and wherein the cross section of the nozzle outlet when viewed in the direction of the center axis varies over the circumference, wherein the cross section is preferably minimal in the region of the centre of the nozzle outlet.

18. A sanitary article arrangement including a sanitary article, in particular a urinal, having a collecting basin and an outlet as well as a spray nozzle according to claim 1 , wherein the nozzle outlet is aligned in such a manner that the collecting basin is wetted and the nozzle outlet is directed toward the outlet.
