1. A color change block with detection feedback, comprising a cleaning agent valve module, a color change micro valve module, a mixing pipe module and a turbidity detection module which are connected in sequence; a complete collinear common channel is formed among these modules, and the wall surface of the common channel is a complete plane;
the turbidity detection module is further connected to a control module and used for monitoring the turbidity of a medium flowing through the common channel in real time, thus determining whether a medium in the common channel meets a cleaning requirement or not and feeding a determination result to the control module, and the control module switches other media to form a closed-loop control.
