Description

Sprinkling can for generating disinfectant fluid by direct current electrolysis

Technical Field

The invention relates to the technical field of sanitary equipment, in particular to a watering can for generating sterilized water through direct current electrolysis.

Background

The electrolysis watering can electrolyzes water in the watering can through the electrodes to obtain electrolytic liquid (the electrolytic liquid has certain disinfection and sterilization effects), and the electrolyte in the watering can is conveyed and sprayed out through the pump body in the watering can, so that the disinfection and sterilization of a target object are realized. Taking the use of the electrode for electrolyzing the salt solution as an example, sodium hydroxide, hypochlorous acid and sodium hypochlorite can be generated in the salt solution after the electrolysis of the electrode, the manufactured chlorine-containing disinfectant solution is widely applied to the disinfection and sterilization of living goods and public environments, and can also remove pesticide remained on the surfaces of vegetables and fruits, and the chlorine-containing disinfectant solution prepared by electrolyzing the salt solution can be easily volatilized after being sprayed on the surfaces of the living goods and the ground, has no residue, and cannot cause any damage to the environment and human bodies; meanwhile, the water solution mainly containing sodium hypochlorite prepared by electrolyzing saline solution has better sterilization and disinfection effects when being applied to public places, and contributes to epidemic prevention and control.

The most important component in the electrolytic watering can is the electrolytic device, the technical core of the electrolytic salt solution generating device lies in the manufacturing technology of the electrolytic electrode, and because the diaphragm type electrolytic salt solution generates sodium hypochlorite and hypochlorous acid with strong oxidizing property, and the overpotential of the positive electrode is very high in the process of electrolyzing the salt solution, the electrode of the electrolytic salt solution must be made of a material with good conductivity, oxidation resistance, low overpotential of oxygen and no reaction with the sodium hypochlorite. At present, few materials capable of meeting the requirements of the electrodes of the electrolytic salt solution water simultaneously cause that the electrodes used at present for the electrolytic salt solution are basically coated with rare metals on the surfaces, the materials commonly used for manufacturing the positive and negative electrodes of the electrolytic salt solution mainly comprise metals such as titanium, platinum, iridium, ruthenium and the like and coatings thereof, and the commonly used titanium alloy is plated with platinum on the surface, or the titanium alloy is coated with iridium, ruthenium alloy, graphite plates and the like on the surface. Wherein, the platinum, iridium and ruthenium alloy materials belong to rare metals, and have high price, which causes the high cost of the electrode. On the other hand, the use environment, the electrolysis process, the structural design, the installation mode and the like of the electrolysis electrode have important influences on the useful function, the electrolysis efficiency and the conversion performance of the electrolysis electrode.

The problems affect the household popularization of the electrolytic watering can and need to be solved.
