1. A cleaning device for dispensing a gaseous medium and/or a medium mixture that consists of the gaseous medium and a liquid medium, the cleaning device comprising:
a mixing element having:
a first feed connection, in a main medium feed line, configured to feed the gaseous medium for passage through the mixing element,
a second feed connection, in a medium feed branch line, configured to feed the liquid medium transversely to the passage into the mixing element, and
a dispensing connection configured to dispense the gaseous medium and/or the medium mixture;
a pressure chamber on the main medium feed line;
a switching valve arranged in the main medium feed line, downstream of or at the pressure chamber, and configured to prevent passage of the gaseous medium through the mixing element in a first switching state and to allow passage of the gaseous medium in a second switching state, the switching valve being formed as a 3/2-way valve or as a double check valve; and
wherein the switching valve is configured as a bridging valve, the bridging valve having a bridging connection for bypassing the mixing element, wherein the bridging connection is connected directly to the dispensing connection.
