DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Parts that act in the same or a similar way are provided with identical reference characters, if expedient.

[0031] Individual technical features of the embodiments described in the following can also be combined in combination with the afore described embodiments as well as the features of the independent claims and dependent claims to subject matter in accordance with the invention.

[0032] FIG. 1 shows a water feature 2 according to the invention with a plug-in nozzle insert 6 inserted into a component 4. The component 4 comprises an illumination unit which is fixedly arranged in the housing 8 and is comprised of a plurality of LED (LED=light-emitting diode) groups 10, wherein the light-emitting side of the component 4 is its top side 14. As can be seen when looking at FIG. 3 also, the component 4 is penetrated centrally by a water channel 12. In a length section of the water channel 12 facing toward the top side 14, the component 4 comprises four projections 18 which are projecting toward the longitudinal center axis A of the water channel 12. In other respects, the water channel 12 comprises a round cross section wherein also the cross section of a length section with a continuous thread along the circumference is understood as round. The projections 18 that adjoin an upper end 16 of the part of the water channel 12 extending in the housing 8 form a part of a nozzle receptacle for the plug-in nozzle insert 6 that is to be inserted from the bottom side 15 of the housing 8.

[0033] FIG. 2 shows the plug-in nozzle insert 6 of the water feature 2 of FIG. 1 in detail. The plug-in nozzle insert 6 has a cylindrical basic shape and comprises four recesses 22 at its end that is facing toward the nozzle exit openings 20; the recesses 22 can be brought into form fit engagement with the projections 18 of the component 4 in the installation position illustrated in FIGS. 1 and 4. Due to the thus achieved form fit engagement, a rotation of the plug-in nozzle insert 6 about the longitudinal center axis A of the water channel 12 is prevented. At its wall surface, the plug-in nozzle insert 6 comprises furthermore a groove 24 for receiving an annular seal.

[0034] FIG. 3 shows only the core housing 8a being a part of the housing 8 of the water feature 2 according to FIG. 1. The projections 18 which are projecting toward the longitudinal center axis A of the water channel 12 are formed as one piece together with the core housing 8a and project past the round circumferential sections 12a of the water channel 12. Each projection 18 comprises an inner contour 26 which adjoins a plane E, E′ that, in at least one perspective transverse to the longitudinal center axis A, is parallel to the longitudinal center axis A. In the illustration according to FIG. 3, the projection 18 to the left of the longitudinal center axis A adjoins a first plane E while the projection 18 positioned to the right of the longitudinal center axis A adjoins the second plane E′. The first plane E as well as the second plane E′ extend in this illustration or perspective parallel to the longitudinal center axis A. The projection 18 which in this illustration is positioned centrally behind the longitudinal center axis A adjoins, on the other hand, a further plane that is extending parallel to the image plane of FIG. 3.

[0035] Each of the projections 18 comprises moreover an abutment surface 28 which is perpendicular to the longitudinal center axis A. This abutment surface 28 forms a stop for the plug-in nozzle insert 6. In the installation position, the lower shoulders 22a of the plug-in nozzle insert 6 (FIG. 2) rest against the abutment surfaces 28. In this way, the plug-in nozzle insert 6 is secured against falling out or being removed from above.

[0036] In FIG. 4, the housing 8 of the component 4 is shown which is comprised of the core housing 8a, a housing cover 8b, as well as a glazing 8c; the plug-in nozzle insert 6 is inserted into the housing 8. The plug-in nozzle insert 6 is fixed at the housing 8 by means of a bottom securing element 30, here in the form of a securing ring which can be screwed into the lower thread 31 of the water channel 12.

[0037] Moreover, FIG. 4 shows an electrical connector 32 at the bottom side 15 of the housing 8 positioned at a distance D from the water channel 12 wherein the distance D is somewhat larger than the length of the lower water channel radius R of the water channel 12.

[0038] FIG. 5 shows the core housing 8a of a further embodiment of the invention in which the projections 18 each form a part of the thread. In this context, the projections 18 are provided with thread segments. The projections 18 form in this context a further fastening possibility for indirect or direct fixation of an insertable nozzle insert 36, illustrated in FIG. 6, that is insertable from above into the component 4. The projections 18 together with their inner contour 26 remain however in place in this context so that still a plug-in nozzle insert 6 to be inserted from below can be secured against rotation and falling out or pulling out.

[0039] FIG. 6 shows a further water feature according to the invention with an insertable nozzle insert 36 inserted from above that, by means of a top securing element 38 screwed into the thread segments of the projections 18, is secured at the component, wherein the top securing element 38 is here in the form of a securing ring engaging around the insertable nozzle insert 36.

[0040] The specification incorporates by reference the entire disclosure of German priority document 20 2020 100 280.5 having a filing date of Jan. 20, 2020.

[0041] While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
