Branching method for negative ions and negative electrons, and application

The invention discloses a method for separating ecological negative ions from a negative electron ground bypass in artificial negative ions by utilizing physical characteristics of an electronic proximity loop, so as to obtain the ''high-concentration, high-safety, ozone-free and static-free'' ecological negative ions. The branching method comprises the steps of: changing a classical relative grounding electrode into annular shape, adopting a grounding electrode (1) such as a screen frame and a pipeline, forming a high-density electron network to carry contaminants in the air to the grounding electrode (1) while negative electrons (6) return to the ground via a grounding electrode proximity loop (8), so that negative electrons (7) being free from any obstruction cover the environmental space in a large area at high concentration. A branching device for the negative ions and negative electrons comprises exposed one-beam or multi-beam conductive fiber emitting electrodes (2), wherein the emitting electrodes (2)
