Abstract

The invention discloses an electrolysis control circuit, a disinfectant manufacturing device and an electrolysis control method. The electrolysis control circuit comprises a control chip, an electrolysis assembly, a first resistor, a second resistor and a diode. According to the arrangement, electrolysis is started with the maximum current in the electrolysis process after starting, and the voltage of the first resistor is higher than that of the second resistor, so that the diode is conducted. At the moment, the electrolysis efficiency is high. Along with the proceeding of electrolysis, the current is gradually reduced, the voltage is gradually increased, the diode is cut off at the moment, and when the current flowing through the electrode plate is smaller than the preset current and thevoltage at the two ends of the electrode plate is equal to the preset voltage, the electrolyte is electrolyzed at the preset maximum voltage until electrolysis is finished. Therefore, the electrolytic current can be well controlled, the electromagnetic noise is eliminated, and the electrolytic efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electrolysis control circuit, a disinfectant manufacturing device and an electrolysis control method. Background technique [0002] With the improvement of people's living standards, many smart appliances have entered people's lives, and the disinfectant manufacturing device is one of the daily use of people. The working principle of the disinfectant manufacturing device is: use electrolysis of sodium chloride aqueous solution to generate sodium hypochlorite solution. Sodium hypochlorite is further decomposed by hydrolysis to form new ecological oxygen, which has strong oxidizing properties and can denature proteins on bacteria and viruses. [0003] The electrolysis of sodium chloride generally uses inert materials such as ruthenium, iridium and titanium as electrodes, and it can be electrolyzed by connecting a direct current of 3V to 10V. Due to the strong cond...
