The display component can be used for displaying various process states (such as an opening state, an activation state, an exhaust state, an inflation state, a cleaning completion state and the like) and various process data (such as the measurement value of the air pressure sensor 4, the detection result of the detector 9, the remaining time of various time lengths and the like) in the cleaning process, and can also be used for sending out an air leakage warning and prompting which cleaning positions have air leakage problems when air leakage is found; in particular, the display component may include, but is not limited to, a display screen and/or status indicator lights. In addition, when the main inlet valve 2 adopts a mass flow controller, the total inflation flow rate can be accurately controlled under the control of the central controller.
And the system is further optimized, and also comprises an operation keyboard which is in communication connection with the central controller in order to conveniently realize the purpose of man-machine interaction operation.
