Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

An intelligent closestool power-off flushing method comprises the following specific steps:

1) when the intelligent closestool controller is powered on and started, according to the interface shown in fig. 2, the mains supply sampling circuit detects the current interface voltage, if the voltage value is lower than a certain threshold value, which indicates that the power-off and water-flushing actions are pressed by a knob at present, the pin 11 for controlling the standby battery power supply loop to be started in fig. 3 is set to be a low level so as to realize the opening actions of the standby battery interface, the standby battery is in a continuous power supply state at the moment, the power-off and water-flushing actions are executed, in the power-off and water-flushing processes, if the mains supply is powered on again, the power-off and water-flushing are stopped, then the standby battery interface is closed, namely the pin 11 for controlling the standby battery power supply;

2) if the power-on detects that the mains supply is supplied, starting to execute normal power-on action, during the power-on process, if the power is cut off, not opening the standby battery, after the power-on is finished, if a water flushing instruction exists, and during the water flushing process, the mains supply is cut off, setting a pin 11 for controlling the standby battery power supply loop to be opened in the figure 3 as a low level so as to realize the opening action of the standby battery interface, wherein the standby battery is in a continuous power supply state at the moment, and performing the power-off water flushing action; similarly, in fig. 2, the commercial power detection module continuously detects the commercial power supply state to control the interface of the standby battery to be in the open or closed state, and after the power-off flushing is completed, the controller sets the pin 11 for controlling the standby battery power supply loop in fig. 3 to be in the high level to close the interface of the standby battery; and starting a new power-on and power-on action judgment until the knob is pressed again.
