Particle-oriented negative ion generator has the functions of promoting, restoring, maintaining health and purifying air. The following is what the particle-oriented negative ion generator can learn from: (1) office, especially suitable for white-collar workers who work in the office most of the day. Long-term absorption of healthy negative ions released by particles directed to the negative ion generator is helpful to eliminate fatigue, refresh the mind and reduce the harm of air conditioning disease. (2) At home, the position of particle-oriented negative ion generator can be adjusted according to different needs of life, such as dust suppression, sleep improvement and daily health maintenance. (3) In beauty salons/health centers, the healthy negative ions released by particle-oriented negative ion generators can resist oxidation, promote microcirculation and tissue nutrient absorption, and double the beauty and health care effects. (4) Hospitals/sanatoriums, under the action of healthy negative ions, can accelerate epithelial regeneration, have antibacterial effect and promote wound healing; At the same time, it is good for the sleep, spirit and mood of the elderly, and can prevent and treat some senile diseases, thus delaying aging and prolonging life. (5) In class, healthy negative ions will have a beneficial effect on teenagers' brain release, personality, mood and behavior, improve the function of cerebral cortex, and cheer up students who have studied for a long time and eliminate fatigue.
