At power-on, the main controller U1 outputs a high level through the wake-up signal output terminal CLR to control the LIN communication chip U2 to start working, and continuously outputs a low level through the first control terminal QD1 and the second control terminal QD 2. Therefore, when the third switching tube Q3 and the fourth switching tube Q4 are both in the off state, the first switching tube Q1 and the second switching tube Q2 are also in the off state, and the dc motor keeps the current state inactive. The LIN communication chip U2 receives a water valve control signal from a sixth pin, which is a communication pin, via a LIN communication bus, from the vehicle controller, where the water valve control signal may include a water valve opening signal and a water valve closing signal, and outputs the signals after conversion to a signal receiving end RXD of the main controller U1, when the main controller U1 receives the water valve opening signal, a high level signal is output via the first control end QD1, a low level signal is output via the second control end OD2, at this time, the first switching tube Q1 is turned on, the second switching tube Q2 is turned off, the first end of the dc motor M1 is grounded, at the same time, the second end of the second switching tube Q2 is also grounded via the second resistor R2, the power supply voltage V1 output from the power supply end is output to the second end of the second switching tube Q2 via the following filter circuit 50 (the filtered power supply voltage V1 is an operating voltage) and is output to the second end of the dc motor M1 via the second switching tube Q2, at this time, the controlled end of the first switching tube Q1 is turned on via the first resistor R1 to the VCC operating state, and thus the first switching tube Q1 is kept in the off state.

In this embodiment, the current limiting protection circuit 40 may be implemented by a fuse, a self-restorable fuse, or a current limiting chip. In practical application, if the current flowing through the current-limiting protection circuit 40 reaches the preset current value due to the short circuit of the circuit in the water valve device, the current-limiting protection circuit 40 can timely disconnect the electric connection path between the power end and the subsequent circuit, or limit the current flowing through the current-limiting protection circuit 40, namely, the current output by the power end, to be below the preset current value, so that the working safety of the water valve device is effectively improved. The preset current value is determined by a researcher and a developer according to the required corresponding device selection.

The cathode of the first diode D1 is connected to the first end of the first capacitor C1, the first end of the second capacitor C2 and the first end of the first switching tube Q1 through the inductor L1, respectively. When the current output by the power supply end exceeds the bearing upper limit of the fuse F1, namely exceeds a preset current value, the fuse F1 is in an off state, so that a passage between the power supply end and a rear-stage circuit is disconnected, and the water valve device is prevented from being damaged by overcurrent. The power voltage F1 output by the power end is stabilized by the zener diode D1 and then filtered by the first diode D1, the inductor L1, the first capacitor C1 and the second capacitor C2, and then the working voltage VCC is output to the input end of the first switching tube Q1 and the input end of the second switching tube Q2 in the implementation, so that the stability of the voltage output to the power end of the driving component 32 is ensured, and the stability and reliability of the operation of the driving component 32 are further ensured.

It is understood that the number of the voltage converting circuits 60 may be plural, and the second voltage of at least one voltage may be outputted to meet the power requirements of different working modules. In practical application, therefore, the water valve device can meet the working requirements of the communication assembly 20 and the main control assembly 31, and meanwhile, the water valve device can be compatible with circuit modules with different voltage requirements, and the compatibility and the expandability of the water valve device are improved.
