Salt content detection method and device, electrolysis control method and device, detection circuit and sterilizer

Abstract

The invention relates to the technical field of disinfectant manufacturing, and discloses a salt content detection method and device, an electrolysis control method and device, a detection circuit and a sterilizer. The salt content detection method comprises the steps: acquiring the magnitude of current between a first electrolysis electrode and a second electrolysis electrode; based on the magnitude of current, determining the electric conductivity corresponding to the current magnitude of current; and determining the salt amount in a current electrolytic solution based on the electric conductivity and a pre-established corresponding relation between the electric conductivity and the salt amount. By implementing the methods and the devices, the salt amount in the current electrolytic solution can be accurately determined under the condition that the salt adding amount is not determined, so that the generation concentration of a sodium hypochlorite solution can be controlled.

Description

technical field [0001] The invention relates to the technical field of disinfectant production, in particular to a salt detection method, an electrolysis control method, a device, a detection circuit and a disinfection machine. Background technique [0002] The disinfection machine uses ordinary table salt as a raw material, mixes it with water to form a sodium chloride solution, and electrolyzes the sodium chloride solution through the positive and negative electrolysis electrodes to produce a sodium hypochlorite solution for disinfection. Disinfection machines currently on the market usually work in a fixed power and fixed time mode, with the amount of salt used as the only change in the preparation of sodium hypochlorite solution, and the concentration of the prepared sodium hypochlorite solution often depends on the amount of salt added. However, different concentrations of sodium hypochlorite solutions are required for different scenarios, and the above preparation meth...
