The invention discloses an intelligent closestool solenoid valve water stop control method. A direct current demagnetization method is adopted; and firstly, a forward current is provided for a solenoid valve for the time t1, and then, a reverse current is provided for the solenoid valve for the time t2. The invention further discloses an intelligent closestool solenoid valve water stop control circuit. The intelligent closestool solenoid valve water stop control circuit comprises a control module and a signal generation module. The output end of the control module is connected with the input end of the signal generation module, and the output end of the signal generation module is connected with the solenoid valve. The signal generation module is controlled by the control module to generate the forward current and the reverse current, and thus, water outlet, water stop and demagnetization of the solenoid valve are achieved. By means of the intelligent closestool solenoid valve water stop control method and circuit, the problem that water stop cannot be achieved after a solenoid valve is used for a long time can be solved through simple refitting.
Description
technical field [0001] The invention relates to a circuit structure of an intelligent toilet, in particular to a method for controlling water stop of an electromagnetic valve and a corresponding control circuit structure. Background technique [0002] After the water outlet solenoid valve of the intelligent toilet is used for many times, the soft magnetic water stop valve core of the normally closed solenoid valve will have residual magnetism due to frequent opening and closing. There is a magnetic force, which causes the valve core to be adsorbed on the fixed iron core and the water cannot be stopped. [0003] In order to solve the above problems, the existing method is to demagnetize the water stop valve core. According to factors such as the use environment, the demagnetization methods used include high-temperature heating, vibration, and providing a reverse external magnetic field. Among them, designing a reverse external magnetic field has become the most commonly u...
