Description

technical field [0001] The invention relates to negative ion generating technology, in particular to a composite material negative ion releasing head, a preparation method thereof and a negative ion generating electrode. Background technique [0002] At present, the most advanced negative ion generation technology at home and abroad basically uses a negative high voltage source, and carbon fiber is made into a discharge electrode, that is, the negative ion release head. The anion releasing head is fixed on the metal rod to form the anion generating electrode. When in application, the negative ion generating electrode is connected to a high-voltage power supply, and the negative ion release head ejects carriers at high speed into the surrounding space. The carriers are quickly captured by air ions to form negative air ions, and at the same time, the positive ions are neutralized by the potential induction of the negative electric field. Reduction, a relatively pure negative ...
