People have more than one hundred years of history of finding the health relationship between negative ions and people. The negative ions are a natural factor, are commonly found in forests, waterfalls, rocks and weather after thunderstorms in the nature, and have good health care effect on human bodies. Clinical trials show that: the air negative ions reduce the level of 5-HT (5-hydroxytryptamine) in brain and tissues by promoting the oxidative deamination of monoamine oxidase (MAO), cause obvious physiological changes of endocrine and nervous system, and have good regulating effect on autonomic nerve higher center and vegetative nervous system, thereby improving the function of cerebral cortex, revivifying, eliminating fatigue, improving work efficiency, improving sleep and increasing appetite.

The research shows that: the health care function of the human body can be realized only in the environment of high-concentration small-diameter particle air negative ions. However, most of the negative ion generators on the market currently adopt a negative high-voltage direct-current discharge technology to generate negative ions. Because of the limitation of the material releasing negative ions, the realization process of the technology releasing high-concentration small-diameter negative ions in the nature is difficult to be completely simulated, and the technology is easy to generate derivatives such as ozone and the like, thereby having great disadvantages.
Therefore, a negative ion generation method capable of generating ecological-grade air negative ions with small particle size and high activity is yet to be developed.
