Abstract
The present disclosure belongs to the technical field of mechanical spraying, and a color change block with detection feedback as well as spraying equipment are provided. The color change block with detection feedback comprises 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 the control module and used for monitoring the turbidity of a medium flowing through the common channel in real time so as to determine whether the medium in the common channel meets a cleaning requirement or not and feed a determination result back to the control module, and then the control module switches other media to form a closed-loop control.
