Sanitary functional unit

Sanitary functional unit (1, 2, 3, 4, 5, 40, 41, 42), comprising:

• a housing (6), which can be releasably fastened to a water outlet of a sanitary outlet fitting, the housing (6) having an outflow-side housing end face (9) with outflow openings (10), the outflow-side housing end face (9) has at least one slot (19), opposing longitudinal sides (20) of the slot form turning engagement surfaces or tool engagement surfaces for a turning tool adapted to be releasably inserted into the at least one slot, and the housing (6) of the functional unit (1, 2, 3, 4, 5, 40, 41, 42) is rotatably held on the water outlet of the outlet fitting or the housing end face (9) is mounted rotatably in relation to the housing (6) on said housing, wherein the housing end face (9) is at least one of rotatably guided in an outflow-side end plane of the functional unit or mounted pivotably about a pivot axis oriented transversely in relation to a longitudinal axis of the housing.

Sanitary functional unit (1, 2, 3, 4, 5, 40, 41, 42), comprising:

• a housing (6), which can be releasably fastened to a water outlet of a sanitary outlet fitting, the housing (6) having an outflow-side housing end face (9) with outflow openings (10), the outflow-side housing end face (9) has at least one slot (19), opposing longitudinal sides (20) of the slot form turning engagement surfaces or tool engagement surfaces for a turning tool adapted to be releasably inserted into the at least one slot, and the housing (6) of the functional unit (1, 2, 3, 4, 5, 40, 41, 42) is rotatably held on the water outlet of the outlet fitting or the housing end face (9) is mounted rotatably in relation to the housing (6) on said housing, wherein the housing end face (9) has a convex or outwardly protruding shape, and said convex or outwardly protruding shape is centered in relation to a midpoint of the housing end face.
