Air purifier is one of the common household appliances in modern people's lives, and its role is to provide a clean and healthy indoor air environment.
One of the important technologies is the release of negative oxygen ions.
Negative oxygen ions are a special type of oxygen molecule that has a charge of negative ions.
Their ** can be thunder and lightning, wind, waterfalls, etc. in nature, or they can be electrical equipment and air purifiers made by humans.
The principle of air purifier releasing negative oxygen ions is mainly as follows:1Photolysis method: The ultraviolet lamp inside the air purifier can produce ultraviolet rays, and when the ultraviolet rays irradiate the oxygen molecules in the air, it will make it ** two oxygen atoms with a charge, forming negative oxygen ions.
2.Electrolysis: Inside the air purifier, the oxygen molecules in the air are ionized by a high-voltage electric field acceleration between the two electrodes, forming charged oxygen ions and corresponding negative ions.
3.Corona discharge method: This is a negative ion generator based on the principle of electric field discharge, which generates high voltage through the electrode, so that the ions in the air collide with the electrode, thus forming a large number of negative ions.
Regardless of the principle of releasing negative oxygen ions, they are able to ionize oxygen molecules in the air to produce negative ions.
When these negative ions react with other pollutants in the air, they can neutralize and settle to the ground to purify the indoor air.
In addition to the release of negative oxygen ions, air purifiers are often equipped with other purification technologies, such as HEPA high-efficiency filtration technology, activated carbon adsorption, etc., to enhance the purification effect.
Among them, HEPA high-efficiency filtration technology mainly filters fine particles such as particles, dust, and pollen in the air through mesh filters;
Activated carbon adsorption can remove odors, formaldehyde and other harmful substances in the air.
However, there are still some controversies about the effectiveness and benefits of negative oxygen ion purifiers.
Some studies believe that negative oxygen ions have a positive effect on inhibiting the growth of bacteria and reducing harmful substances in the air, which can help improve indoor air quality.
However, some studies have shown that the number of negative oxygen ions is not the decisive factor, and too many negative oxygen ions may have inflammatory effects and pose potential risks to human health.
When buying and using air purifiers, consumers need to look at the function of negative oxygen ions rationally.
You should also choose the right purifier and choose the right product according to your own needs and environmental conditions.
Air purifiers purify indoor air by releasing negative oxygen ions, and their principles are varied.
Air purifiers often use other purification technologies to improve the purification effect.
Consumers should rationally look at the role of negative oxygen ions when purchasing and using air purifiers, and choose the right products.
