1. A discharge head for discharge of liquid, the discharge head comprising:
a discharge channel and a discharge opening at an end of the discharge channel;
an outer shell with a discharge aperture, wherein liquid delivered through the discharge opening is discharged through the discharge aperture;
the discharge head further comprising:
an inner body, the discharge opening being disposed on the inner body, the inner body being rotatable relative to the outer shell about a switching axis, wherein the discharge opening, in an open rotational position, is arranged in alignment with the discharge aperture of the outer shell and, in a closed rotational position, the discharge opening is covered by the outer shell, or
a screen body arranged within the outer shell, the screen body being rotatable relative to the outer shell about a switching axis, wherein the screen body has a blocking section, the blocking section, in a closed rotational position, being arranged between the discharge opening and the discharge aperture in the outer shell and, in an open rotational position, the blocking section opening up the discharge aperture,
the discharge head further comprising a releasable snap-action coupling including a release surface, the outer shell being rotationally coupled to the inner body or the screen body in the closed rotational position by the releasable snap-action coupling such that the open rotational position is reachable again only after manual application of force to the release surface of the releasable snap-action coupling, the releasable snap-action coupling further including an elastically radially inwardly deflectable latching extension projecting outwardly from the inner body or from the screen body, and a corresponding retaining aperture or retaining profiling on the outer shell, the retaining aperture of the outer shell being formed by the discharge aperture.
