Abstract

The invention discloses a concentration detection circuit, a disinfectant manufacturing machine and a control method of the disinfectant manufacturing machine. The control method comprises the steps that the initial concentration of an electrolyte is obtained; according to a preset relation between electrolyte concentration and electrolytic current, a preset current change rule matched with the initial concentration is determined, and electrolysis is started according to preset current in the preset current change rule. Through the arrangement, the electrolytic current matched with the initialconcentration of the electrolyte can be determined according to the initial concentration of the electrolyte so that the disinfectant manufacturing machine can be prevented from conducting electrolysis at fixed electrolytic power all the time; when the concentration of the electrolyte is relatively high, the electrolysis can be conducted at relatively high electrolytic current, so that the electrolytic efficiency is improved; and when the concentration of the electrolyte is relatively low, low current is kept for electrolysis so that the electrolyte can be completely electrolyzed, and an optimal disinfectant preparation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a concentration detection circuit, a disinfectant manufacturing machine and a control method thereof. Background technique [0002] With the improvement of people's living standards, many smart appliances have entered people's lives, and the disinfectant making machine is one of the people's daily use. The working principle of the disinfectant making machine 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] In the process of sterilizing and killing viruses, hypochlorous acid can not only act on the cell wall and virus shell, but also penetrate into the body of bacteria (viruses), and oxidize with organic polymers such as bacteria (virus...
