Claim 20:
21. A sanitary insert unit (1, 6, 12), comprising:
an insert housing (2) which is mountable on or in a water outlet (3) of a sanitary outlet fitting, the insert housing including a housing interior through which a liquid path is provided that is adapted to direct a water flow through the housing interior,
a jet splitter (9, 10) located in the liquid path and includes a plurality of splitter openings (11, 13) which are adapted to divide water flowing therethrough into a plurality of individual jets,
at least one lattice or mesh structure (14, 15) following the jet splitter (9, 10) in the liquid path,
a bypass duct (16) that partially bypasses the liquid path such that water is adapted to simultaneously flow in the liquid path and the bypass duct (16), the bypass duct (16) comprises a nozzle with a narrowing clear duct cross section which includes a first tapered section that transitions from a widest open clear duct cross-section and a second tapered section downstream of the first tapered section that is adapted to create at least one accelerated liquid jet that is configured to be separately discharged from an outflow end of the insert housing (2) from the water flow through the at least one lattice or mesh structure,
wherein the bypass duct (16) narrows or tapers in a direction toward an outflow-side duct opening in order to form the nozzle that has a smallest clear cross-section proximate to an outlet of the bypass duct, and
the at least one lattice or mesh structure (14, 15) extends from the first tapered section to the outflow end.
