Negative oxygen ions, known as "air vitamins", are beneficial to the body's physical and mental health. It mainly affects the human body's physiological activities through the human nervous system and blood circulation. Negative oxygen ions can strengthen the cerebral cortex inhibition process and regulate the function of the cerebral cortex, so it can play a role in sedation, hypnosis and blood pressure reduction; after the negative oxygen ions enter the human respiratory tract, the bronchial smooth muscle relaxes and relieves its phlegm; When ions enter the human blood, the red blood cell sedimentation rate can be slowed down, the clotting time is prolonged, the red blood cell and blood calcium content can be increased, the white blood cells, blood calcium and blood sugar are decreased, and the lactic acid content in the fatigue muscle is also reduced. Negative oxygen ions can strengthen the oxidation process of the kidney, liver, brain and other tissues of the human body, and the brain tissue is most sensitive to negative oxygen ions.
Eco-grade anion is an air negative ion equivalent to nature and has good biological activity. Moderate increase of negative oxygen ions in the air in areas where people are relatively concentrated helps employees to concentrate, improve work efficiency and reduce errors, and at the same time, it can play a role in health care, prevention and treatment of diseases.
The negative ion generator provided by Shengjie Company generates negative electrons by simulating the high-voltage ionized air of natural lightning, and ionizes the air through the negative pole of the needle tip to generate a high concentration of negative oxygen ions, and the release concentration is more than 20 million/cm3. The newly developed high-voltage conversion technology can produce ecological-grade small-size negative ions, which are farther away and more easily absorbed by the human body.

A negative oxygen ion generating device is usually installed and used in combination with an air purifying device in order to exert its optimum effect;
Usually, the equipment is installed at the indoor air supply vent (the distance from the air vent is not less than 100mm), the equipment is controlled by air and linked with the air supply system; when the concentration of particulate matter in the indoor air is high, the negative oxygen ions will mainly act as sediment particles. Therefore, the indoor air cleanliness needs to be fully considered before installing the equipment.
