Abstract

A water stop control method and circuit for a solenoid valve of an intelligent toilet. The water stop control method comprises: by using a direct current demagnetization method, first providing a forward current at time t1 for a solenoid valve, and then providing a reverse current at time t2 for the solenoid valve. The control circuit comprises a control module and a signal generation module, wherein an output end of the control module is connected to an input end of the signal generation module, and an output end of the signal generation module is connected to the solenoid valve; under the control of the control module, the signal generation module generates a forward / reverse current, so that water outlet, water stop, and demagnetization of the solenoid valve are implemented. The technical solution can resolve, by means of a simple modification, the problem that a solenoid valve is unable to stop water after being used for a long time.

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 use...
