2. A control method of a compact household water purifier complete machine device, which is characterized in that the compact household water purifier complete machine device of claim 1 is used for implementing control operation, and the method comprises the following steps:
the controller circuit detects whether the reverse osmosis membrane filter is electrified currently or not in real time, controls the water inlet electromagnetic valve to be opened when the controller circuit detects that the reverse osmosis membrane filter is electrified for the first time, and controls the booster pump to be started to perform water injection pressurization operation on the reverse osmosis membrane filter;
when water is taken normally, when the water purifying faucet is opened, the high-voltage switch senses that the pressure of a water path is reduced and sends a low-voltage signal to the controller circuit, and the controller circuit controls the booster pump to start and the water inlet electromagnetic valve to open to implement water purifying action after being electrified;
when the water purifying faucet is closed, the high-voltage switch senses the increase of the pressure of the water path and sends a high-voltage signal to the controller circuit, and the controller circuit controls the power supply device to perform power-off operation;
and executing water leakage detection operation:
the water leakage detection chip monitors whether the device leaks water or not, and sends a water leakage alarm signal to the controller circuit if the device leaks water;
the controller circuit controls the power supply device to power off after receiving the water leakage alarm signal;
performing real-time overheat monitoring and overheat protection operations:
the thermal protection module monitors whether the continuous operation of the booster pump exceeds a standard time threshold or a standard temperature threshold, and sends an overheating alarm signal to the controller circuit if the continuous operation of the booster pump exceeds the standard time threshold or the standard temperature threshold;
the controller circuit controls the power supply device to power off after receiving the overheating alarm signal;
performing a periodic high pressure flush operation:
the controller circuit presets a washing period and a washing duration after the power is switched on for the first time;
the controller circuit sends a flushing instruction to the high-pressure flushing solenoid valve when a flushing period is reached after the power supply is switched on for the first time;
the high-pressure flushing electromagnetic valve is used for receiving a flushing instruction and carrying out high-pressure flushing operation on the reverse osmosis membrane filter according to the specified flushing time.
