The plug-in J1 is connected to a 220-volt power supply. After the circuit is powered on, the resistor R1 and the capacitor C1 generate super-audio frequency oscillation with a frequency of about 20kHz.

Small particle size negative ions are also called light ions or small ions. They are a kind of air negative ions that are equivalent to nature. Some sources also call them ecological grade negative ions. It has the characteristics of long migration distance and high activity. Air negative ions are divided into three types according to their migration distance and particle size: large, medium and small ions. What is beneficial to humans is small ions, also known as light ions, which have good biological activity. Only small ions or small ion clusters can enter the organism.

Medical research shows that it is negative ions with small particle size that have health care effects on the human body. Because only negative ions with small particle sizes can easily pass through the blood-brain barrier of the human body and exert their biological effects. The reason why air negative ions in nature have created many longevity villages is because the proportion of small particle size negative ions is high. Due to the high activity and long migration distance of small particle size negative ions, they form a negative ion bath environment over longevity areas. The reason why many negative ion home appliances The effect is not good, because it is difficult to generate ecological negative ions with small particle size by using traditional negative ion generation technology. The health care effect on the human body is general, only the effect of dust removal and dust reduction, and it is generally used in the field of air purification.

The book "Environmental Health and Negative Oxygen Ions" written by Professor Lin Jinming, a doctoral supervisor of Tsinghua University and an expert from the Chinese Academy of Sciences, defines as follows: Positive and negative ions in the air can be divided into large, medium and small ions according to their mobility. What is beneficial to the human body are small ions, also known as light ions, which have good biological activity. Only small ions or clusters of ions can enter the organism.

Positive and negative ions in the air can be divided into large, medium and small ions according to their mobility. Ion mobility greater than 0.4c㎡/(V`s) is a small ion, less than 0.04/(V`s) is a large ion, and between the two is a medium ion. Charged atomic groups or molecular groups close to the molecular size belong to small air ions. These small air ions have a high speed of movement, collide with each other in the atmosphere, and continue to gather to form large or medium ions. Only small ions, or clusters of small ions, can enter the organism. The small negative oxygen ions, or clusters of small negative oxygen ions, have good biological activity.

The moving speed of ions under the action of unit intensity (V/m) electric field is called ion mobility, which is an important parameter to distinguish the diameter of the measured ion. The smaller the diameter of air ions, the faster their migration speed. Ion mobility is an important parameter to express the size of the ion to be measured. The ion velocity is inversely proportional to the ion diameter, and the ion mobility is directly proportional to the ion velocity, so the ion mobility is negatively proportional to the ion diameter.
