Electrolysis control circuit, control method and disinfectant manufacturing device

The invention discloses an electrolysis control circuit, a control method and a disinfectant manufacturing device. The electrolysis control circuit comprises a first electrode, a second electrode, a first switching circuit and a comparison circuit. Thus, in the embodiment, when the comparison signal received by the control module is switched from the low level to the high level, the conduction time of the first switch circuit is determined, and the conduction time of the first switch circuit is the charging time required for charging the electrolysis assembly to the voltage of the reference signal. The longer the charging time is, the higher the capacitance is, namely, the higher the salt solution concentration is; the shorter the charging time is, the smaller the capacitance is, namely the lower the salt solution concentration is. Therefore, a proper amount of salt can be added by a user in the using process, the concentration of the salt solution is matched with the electrolysis voltage provided by the powe
