The utility model relates to an electronic activated water generator. The high-voltage output end of the coupling self-excited oscillation circuit of a DC high-voltage transformer is connected with electric field grids. The electric field grids are divided into annular shape and square frame shape two sorts and are composed of a rigid insulation outer frame and a plurality of conducting metal sheets. The surfaces of the metal sheets are sealed with insulation materials; the planes among the metal sheets are relative, are arranged in parallel in equidistance and are left with a space layer; the inputs of the electrode circuits of the metal sheets keep to the matched sequence of positive-negative unusual electrodes; the electrode circuit is led out from top. When working, the space layer of the electric field grid generates uniformly strong pulse high-voltage electric field to excite natural water to become activated water. The utility model has less power consumption, high efficiency and wide purposes.
