(C) a reverse control step: when the stuck state determining step determines that the flow passage of the water control valve 20 is stuck, the electric control processing unit 60 commands the driving motor 30 to perform a reverse rotation motion, so that the water control valve 20 synchronously generates a reverse rotation motion;
(D) a reverse state sensing step: the detection operation module 61 detects and senses whether the water control valve 20 is smoothly reversed and returns to the opening mode or the closing mode again, if so, the clamping state is determined to be released, and if not, the clamping state is determined not to be released;
(E) a repeated inversion step: when the reverse rotation state sensing step determines that the water control valve 20 is not released from the stuck state, repeating the steps (C) to (D) to a predetermined number of times (for example, 3 to 5 times is a preferred range of times);
(F) an automatic shutdown step: when the water control valve 20 in the step (E) is repeatedly rotated for the predetermined number of times and the detection operation module 61 still determines that the water control valve 20 is in the stuck state, the electronic control processing unit 60 turns off the watering timer 100 to stop operation.
The on/off state sensing step is implemented by providing a sensor to detect the mode of the water control valve 20 (the specific structure is described in detail later).
