Problems solved by technology

Such a high negative pressure is not only costly, but also tends to generate static electricity on the negative ion release head and the metal around it, reducing the safety of the negative ion generator, bringing fear to the user, and even threatening the personal safety of the user
In addition, due to the low strength of carbon fiber, the external environment is easy to affect the performance of the release head, and the surface of cellulose is easy to absorb dust, requiring frequent cleaning, so its maintenance cycle is short and its service life is also affected

Abstract

The invention discloses a composite material negative ion release head. The composite material negative ion release head comprises a conductive metal wire, a carbon nanotube array and a fullerene layer. The carbon nanotube array comprises a plurality of carbon nanotubes, the plurality of carbon nanotubes are formed on the conductive metal wire, and the fullerene layer is formed on a part, which isnot covered by the carbon nanotube array, of the conductive metal wire and the carbon nanotube array. The invention also discloses a method for preparing the composite material negative ion release head and a negative ion generation electrode. The composite material negative ion release head can release more negative ions under lower negative pressure, almost no ozone, nitric oxide and other byproducts are generated, and the service life is long.

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 carbon fiber negative ion release head ejects electrons at high speed into the surrounding space, and the electrons are quickly captured by air ions to form air negative ions. A relatively pure negative ion field. At present, the carbon fiber material used in the more advanced negative ion release heads on t...
