DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0041] FIGS. 1 to 4 will be described together below.

[0042] A sanitary insert part (denoted as a whole by 1) has a housing 2. The housing 2 may in this case be of – as illustrated – single-part or multi-part form.

[0043] An outlet structure 4 is formed on a downstream side 3 and, in a manner known per se, forms an exiting water jet.

[0044] An upstream screen 5 is arranged on the upstream opposite side 6 of the sanitary insert part 1.

[0045] The housing 2 delimits an interior space 7. A connecting element 8 is provided so as to run through the free interior space 7 completely and connects the outlet structure 4 to the upstream screen 5.

[0046] By way of the connecting element 8, the upstream screen 5 is snap-fitted to the outlet structure 4 in a manner to be described in more detail.

[0047] Multiple functional units 9 are arranged in the interior space 7 of the housing 2.

[0048] The connecting element 8 is inserted through each functional unit 9.

[0049] In the exemplary embodiment, it can be seen that a functional unit 9 which is arranged directly after the upstream screen 5 is in the form of a jet splitter 10.

[0050] In the exemplary embodiment, the jet splitter 10 is designed as a splitter plate. In further exemplary embodiments, the jet splitter 10 may also be designed as a diffuser with a diffuser ring.

[0051] In further exemplary embodiments, it is possible for there to be arranged upstream of the jet splitter 10 for example also at least one flow regulator for setting a pressure-independent throughflow.

[0052] In the exemplary embodiment as per FIGS. 1 to 4, there is a further functional unit 9 in the form of a diversion insert 11 downstream of the jet splitter 10.

[0053] It can be clearly seen in FIG. 2 that the diversion insert 11 is shaped inward in such a way that an exiting jet from the jet splitter 10 is diverted radial inward in order for thorough mixing to be achieved below the jet splitter 10.

[0054] In further exemplary embodiments, it is additionally or alternatively possible for screen inserts known per se also to be arranged in the interior space 7.

[0055] In the exemplary embodiment as per FIGS. 1-4, a mechanical interface 12, which produces the snap-action connection, is formed at the upstream screen 5 and the corresponding end of the connecting element 8.

[0056] The opposite end of the connecting element 8 is formed integrally on the outlet structure 4.

[0057] Consequently, for producing the snap-action connection, the upstream screen 5 is plugged onto the connecting element 8. On the connecting element 8, there is formed a thickening 13 which interacts with radial slits 14 in the upstream screen 5 so as to produce the snap-action connection.

[0058] FIG. 3 clearly shows that the housing 2 has an undercut-free, cylindrical inner contour 15.

[0059] The functional units 9 are thus supported axially against the outlet structure 4.

[0060] It can be seen that the connecting element 8 is in the form of a holding pin 16 which is arranged centrally on a longitudinal central axis 17 of the housing 2.

[0061] In the sectional illustration in FIG. 2, it can be seen that the outlet structure 4 is formed on the housing 2 and is thus connected integrally thereto.

[0062] The upstream screen 5 is supported at its outer periphery 20 against the housing 2 via an encircling sealing ring 18. The upstream screen 5 is moreover supported at its outer periphery 20 against the outlet structure 4, and thus likewise against the housing 2, via the functional units 9 and the mentioned sealing ring 18.

[0063] On the jet splitter 10, there is formed a support sleeve 19 via which the upstream screen 5 is supported centrally.

[0064] In the exemplary embodiment, the housing 2 is introduced into a screw sleeve 21.

[0065] The screw sleeve 21, as a screw-in sleeve, has, in a manner known per se, an outer thread 22, which – as FIG. 4 shows – can be screwed to a fitting outlet 23. In this case, the sealing ring 18 can affect sealing.

[0066] In further exemplary embodiments, the outer thread 22 may be formed directly on the housing 2. It is also possible for an inner thread to be formed on the housing 2 or on a screw sleeve 21 (screw-on sleeve) in order for a screw connection to a fitting outlet 23 to be produced. In further exemplary embodiments, other connections, for example snap-action and/or bayonet connections, are provided.

[0067] The housing 2 has, in a manner known per se, aeration windows 24 which lead to the outside via an aeration channel 25 between the housing 2 and the screw thread 21.

[0068] FIGS. 5 and 6 show a further exemplary embodiment according to the invention. Functional units and components which are identical or similar in terms of function and/or construction to the previous exemplary embodiment are denoted by the same reference signs and are not described separately again. The statements in relation to FIGS. 1-4 therefore apply correspondingly to FIGS. 5 and 6.

[0069] The exemplary embodiment as per FIGS. 5 and 6 differs from the preceding exemplary embodiment in that the interface 12 is formed not at the upstream screen 5, but in the connecting element 8.

[0070] One part of the connecting element 8 is consequently formed on the outlet structure 4, and a second part of the connecting element 8 is by contrast formed on the upstream screen 5.

[0071] FIG. 7 shows a further exemplary embodiment according to the invention. Again, functional units and components which are identical or similar in terms of function and/or construction to the previous exemplary embodiment are denoted by the same reference signs and are not described separately again. The statements in relation to the preceding exemplary embodiments therefore apply correspondingly to FIG. 7.

[0072] The exemplary embodiment as per FIG. 7 differs from the preceding exemplary embodiments in that the mechanical interface 12 is formed at the outlet structure 4. In this case, the connecting element 8, which may be formed integrally on the upstream screen 5, is thus snap-fitted to the outlet structure 4 via a thickening 13.

[0073] FIG. 8 shows a further exemplary embodiment according to the invention. Again, functional units and components which are identical or similar in terms of function and/or construction to the previous exemplary embodiments are denoted by the same reference signs and are not described separately again, the statements in relation to FIGS. 1 to 7 therefore applying correspondingly to FIG. 8.

[0074] The exemplary embodiment as per FIG. 8 differs from the preceding exemplary embodiments in that the connecting element 8 does not have a substantially constant diameter, but rather a shoulder 26 is formed at the height of a functional unit 9, on which shoulder the functional unit 9 – here the jet splitter 10 – is supported centrally.

[0075] For the sanitary part 1, it is thus proposed for a connecting element 8 to be arranged into an interior space 7 of a housing 2 spaced apart therefrom and to be used for snap-fitting of an inflow-side upstream screen 5 to an outflow-side outlet structure 4.
