Rapid feedback device and method for water inlet fault of intelligent closestool and intelligent closestool

The invention relates to the technical field of intelligent closestools, in particular to a rapid feedback device and method for a water inlet fault of an intelligent closestool and the intelligent closestool. The pre-filter is communicated with the water storage chamber through an ingress pipe, and an electromagnetic valve is arranged on the pre-filter; the trigger switch is used for controlling the conducting state of the electromagnetic valve; the follow-up mechanism comprises a buoyancy lifting assembly, a pushing assembly and a stopping plate, when the water amount in the water storage cavity is changed, the buoyancy lifting assembly can drive the stopping plate to move through the pushing assembly, the water pressure action mechanism is arranged in the water tank, and the water pressure action mechanism comprises a hydraulic driving assembly, a driven assembly and an abutting part; when water flows through the ingress pipe, the hydraulic driving assembly can drive the stop plate to move towards or away
