[0002] The ionized water preparation devices in the prior art usually use electrolysis to separate water into alkaline and acidic water through a diaphragm. There are the following technical defects: 1) Due to the lack of real-time detection and feedback systems, these devices cannot automatically adjust the electrolysis parameters according to changes in water quality, resulting in fluctuations in water quality and affecting the use effect; 2) The water generated by traditional ionized water preparation devices is usually not directly drinkable and needs further treatment to meet drinking standards, which increases the complexity and cost of use.

[0003] Therefore, how to design an ion water preparation device that can detect water quality in real time and automatically adjust electrolysis parameters, and how to design an ion water preparation method that can adjust the voltage difference of the actual applied voltage have become urgent problems to be solved.

[0008] S2, electrolysis,

[0009] The electrolysis unit is started by the PLC controller, and the positive electrode in the anode chamber and the negative electrode in the cathode chamber electrolyze the pre-treated water respectively. The positive electrode generates acidic ion water after discharge, and the negative electrode generates alkaline ion water after discharge;

[0015] ①The PLC controller compares the detected pH value with the conductivity comparison table based on the collected water quality detection unit data to obtain the corresponding conductivity;

[0016] ②Calculate the applied voltage,

[0017] The reciprocal of resistivity is conductivity, from which we can get the relationship equation of Ohm's conductivity law G=I / U, and the formula is transformed into U=I / G.

[0018] Where I is the current passing through the conductor; U is the applied voltage; G is the conductivity of the ionic conductor;

[0019] The PLC controller calculates the actual applied voltage while keeping the current value unchanged;

[0020] ③Calculate the voltage difference to be adjusted,

[0021] The PLC controller stores the set pH value and the corresponding voltage. The difference between the stored voltage and the actual applied voltage is calculated to obtain the voltage difference;

[0022] ④Adjust the voltage of the electrolysis unit,
