The tap water in the municipal city is the water source of our machine. Firstly filtering tap water through four filters and absorbing and other processions and then decomposing by Electrolysis Chamber, due to the influence of hydrogen bond, the ordinary tap water is composed of 13 to 15 small molecular clusters, when the water enter into the electrolysis chamber, the hydrogen bond of water molecule is opened with the influence of electric field and produces the small molecular cluster water with 5 to 6 water molecules. At the same time, the positive ions such as Ca2+,Mg2+,K+,H+ and so on in solution move toward the negative pole with the influence of electric field. According to the strength of electro negativity’ capability, H ion has a reduction then the electro negativity becomes hydrogen. Due to the fact that the density of H ion decreases, the hydroxide root ion is thicker and then water become weak alkaline with the PH up to 7, the water produced in this pole is alkaline water. At the time , in the positive pole some of negative ions such as Cl-,SO42-,NO3-,NO2-,OH- etc move to positive pole. Among plenty of negative ions, the hydroxide root ion loses electrodes easterly and then has an oxidative reaction and produce oxygen and water with the loss of electrodes. At the same, the density of H ions rises because density of the hydroxide root ion decreases so the water becomes weak acid with PH down to 7 so the water produced is acid ionic water.  The chemistry formulas in two poles are as follows:

In negative pole: 2H2O+2e=2OH-+H2

In positive pole: 2H2O-4e=4H++O2
