The nozzle head 3 is mounted in the interior 8 of the pipe section 7 and can be inserted into the interior 8 via the outlet 11. The nozzle inlet 5 is accessible from the interior 8 of the pipe section 7 ago, so that rinse water from the interior 8 in the nozzle channel 4 of the nozzle head 3 can occur. The nozzle head 3 is arranged in the interior 8 so that the nozzle outlet 6 from the interior 8, in particular from the output 11, also protrudes. The nozzle exit 6 is thus not in the interior 8, but is correspondingly free, so that rinse water can exit from the nozzle exit 6. The nozzle head 3 is secured or fixed via a securing element 12 in the interior 8 of the line piece 7.

The fuse element 12 according to the first embodiment according to the FIGS. 1 to 9 is groove and comb connection 14, 15 and the securing element 12 according to the second embodiment according to the FIGS. 10 to 18 is a cover 17. These two embodiments are then explained in detail below.

The power piece 7 has here on the outside in the region of the output 11 a circumferential flange 34. The flange 34 serves as a stop element when installed in The sanitary article 2. Furthermore, the spray nozzle 1 here comprises a union nut 35, which is connectable to the pipe section 7, so that it can be clamped together with the flange 34 to the sanitary article 2. Between the union nut 35 and the flange 34 is a gap which serves to receive parts of the sanitary article. In the assembled state, the pipe section 7 is in communication with the sanitary article. In the embodiment shown, it protrudes through an opening in the sanitary article 2.

The water pipe 10 protrudes into the interior 8 via the inlet 9 and is fastened to the pipe section 7 with another union nut 36. The threads for the union nut 35, 36 are arranged on the outer circumference of the line piece 7.

Next, the nozzle head 3 and the line piece 7 in the embodiment shown alignment elements 13, so that the nozzle head 3 is rotatably mounted in its installed position with respect to a movement about the central axis M in the interior 8 of the pipe section 7. This ensures that the nozzle outlet 6 is always in the correct orientation, so that the sanitary article can be wetted or rinsed as intended. The correct orientation is shown in the sectional view of Figures 3 and 13 shown. The nozzle exit 6 is directed against the catch basin 33 of the sanitary article 2. Depending on the embodiment, the alignment elements 13 may be formed differently.

The securing element 12 according to the first embodiment of the spray nozzle 1 according to the FIGS. 1 to 9 has the shape of a groove and comb connection 14, 15 between the nozzle head 3 and the interior 8. This compound can be particularly well in the context of Figures 2 and 3 be recognized. In the FIG. 2 the groove 14 is shown on the outside of the nozzle head 3. The comb 15 can in the FIG. 3 be well recognized. The comb 15 protrudes into the interior 8 of the pipe section 7. Via the groove and comb connection 14, 15 a stop for the nozzle head 3 in the interior 8 is provided against movement in the direction of the central axis M.

The groove and comb connection 14, 15 is preferably formed such that it has a partial section 16, which is formed with respect to the central axis M at least partially circumferential and along the central axis M extending in a longitudinal direction. The formation of the groove and comb connection 14, 15 is therefore such that a rotation of the nozzle head 3 in the stationary interior 8 results in an axial displacement A along the central axis M.

This function of the groove and comb connection 14, 15 will now be described with reference to FIGS. 4a to 9 explained in more detail. In the FIG. 4a and the associated section 4b is the nozzle head 3 in its mounted position in the interior 8. In the FIGS. 5a and 5b is a cover 17, which covers the nozzle head 3 front, removed and the nozzle head 3 is accessible to the installer. Accessibility is in the FIG. 6 shown in more detail.
