Description

technical field [0001] The invention relates to an intelligent electrolyzed water machine acquisition signal processing circuit and method. Background technique [0002] Electrolyzed water is a process of electrolysis on the basis of tap water without adding any substances through the cathode and anode electrode plates under a specific constant voltage and current. Through the conversion of electric energy, the physical structure of water is changed. Due to the aggravation of water pollution and secondary pollution, there are tens of thousands of substances per milliliter of water. Electrolysis itself is also a process of purifying water quality, and then separated by ion membrane to separate minerals that are beneficial to human body absorption. , trace elements; acid radical ions are also separated to obtain beneficial daily water, such as: cleaning, astringent skin, acidic water soaking feet, sterilization and other functions. In simple terms, the electrolysis process ph...
