In-Vehicle Ecological Negative Ion Generator

Concept and Functions of Negative Ions

✪ Concept

In the natural environment, among the various gas molecules that make up air, oxygen and carbon dioxide molecules have a stronger ability to "capture" free electrons. Since oxygen constitutes a larger proportion of air, most free electrons generated by air ionization are "captured" by oxygen molecules, forming negative oxygen ions, abbreviated as negative ions.

✪ Functions

Negative ions are gas ions carrying a negative charge in the air. They not only facilitate the synthesis and storage of vitamins in the human body but also strengthen and activate physiological activities, exerting a significant influence on the life processes of humans and other organisms. Hence, they are often called "air vitamins." Like dietary vitamins, they play a crucial role in the life activities of humans and other living beings. Some even believe that air negative ions are associated with longevity, dubbing them "longevity elements." Air negative oxygen ions are hailed as the vitamins of the air, capable of degrading and neutralizing harmful gases. They regulate physiological functions, eliminate fatigue, improve sleep, prevent respiratory diseases, ameliorate cardiovascular and cerebrovascular diseases, lower blood pressure, enhance appetite, and improve skin elasticity.

The reason air feels fresher after a thunderstorm is that gas molecules in the air dissociate under the influence of lightning, releasing negatively charged negative ions. Negative ions move in a zigzag pattern in the air. They transfer negative charges to bacteria, dust, smoke particles, and water droplets. These charges combine with the particles, causing them to aggregate into clusters and settle, thereby purifying the air. Negative ions possess dual functions of health preservation and environmental protection, helping to alleviate mental fatigue and boost energy and spirit.

We perceive air as particularly fresh in natural environments like forests, waterfalls, and oceans because the concentration of negative ions in the air increases. The higher the concentration of negative oxygen ions, the better the air quality.

Concept and Healthcare Principles of Small Particle Size Negative Ions

✪ Concept

Small particle size negative oxygen ions are responsible for the medical and healthcare effects on the human body. This is because only small particle size negative oxygen ions can easily penetrate the blood-brain barrier to exert their biological effects.

✪ Functions

Negative oxygen ions have medical and healthcare functions, primarily due to their prominent antioxidant (reductive) and anti-aging effects. The antioxidant (reductive) property of negative oxygen ions is based on a fundamental chemical principle: chemical reactions involve the exchange of electrons in electron shells. Losing electrons is called oxidation, while gaining electrons is called reduction. Molecules (or groups) or atoms that lose electrons exhibit positive charge and are called positive ions; those that gain extra electrons exhibit negative charge and are called negative oxygen ions. Therefore, negative oxygen ions carry a negative potential, meaning they have excess electrons that can be supplied to aging cells or blood cells. This achieves antioxidant and anti-aging effects, reducing free radicals.

Negative oxygen ions are oxygen ions that have gained extra electrons. In living organisms, when lipids lose electrons, they oxidize into age spots; when proteins lose electrons, cell functions become impaired; when genes lose electrons, cancer may develop. In living organisms, substances that seize electrons are called "free radicals." From the perspective of quantum medicine, electron loss is the root cause of all diseases. Similarly, rusting iron, weathering stone, and rotting plants are all results of oxidation. Negative oxygen ions carry a negative potential, meaning they have excess electrons. When these electrons are supplied to free radicals, the free radicals are reduced and eliminated, while the negative oxygen ions themselves transform into oxygen molecules (O2).

Principle of Negative Ion Dust Removal

• When the concentration of negative oxygen ions in indoor air reaches 20,000 per cubic centimeter, airborne dust can be reduced by over 98%. It is highly effective against respirable particulate matter PM2.5.

• Negative oxygen ions can actively capture small positively charged dust particles in the air, causing them to coagulate and settle. This effectively removes particulate pollutants from the air. The air purification effect of negative oxygen ions stems from their combination with positively charged particles such as bacteria, dust, and smoke in the air, forming clusters that settle, thereby achieving air purification.

• Negative ions can coagulate and settle fine particulate matter, a fact proven by experiments conducted in the U.S. Environmental Protection Agency (EPA) laboratory.

• The statement that negative ions only coagulate and settle particulate matter without removing them, and that they can be re-suspended by activities like walking, is to some extent correct. This is similar to filter-based air purifiers that merely trap and adsorb particles on filters without completely eliminating them. However, when small particles coagulate into larger ones, their harm to the human body is significantly reduced. For example, respirable particulate matter PM2.5 is only 1/20th the thickness of a human hair and invisible to the naked eye. It can penetrate nasal hair, respiratory mucosa, and other barriers to reach the lungs, clogging alveoli and impairing lung ventilation and gas exchange. Under the influence of negative ions, these particles coagulate into larger ones and settle on the ground. Even if re-suspended by external forces, they become visible due to their increased size. These larger particles are often blocked by nasal hair, respiratory mucosa, and other barriers and expelled from the body through mucus and phlegm, thereby significantly reducing their harm.

Principle of Negative Ion Sterilization and Formaldehyde Removal

Formaldehyde is a toxic substance carrying a positive charge, i.e., a positive ion. It is inherently unstable and can damage cells upon contact with living organisms such as humans and plants, leading to weakened bodily functions, decreased immunity, and increased susceptibility to diseases.

Negative ions can remove formaldehyde. Negative ions are oxygen atoms with extra electrons, generated by water, air, sunlight, and terrestrial radiation. Research shows that negative ions have good air purification and disinfection effects. By increasing the concentration of negative ions in indoor air, air quality can be improved. In removing formaldehyde, negative ions can decompose it into carbon dioxide and water, which are then expelled outdoors with airflow.

Issues with Current Mainstream Air Purification Products

Air purifiers using technologies such as negative ions, electrostatic precipitation, photocatalysis, and ultraviolet lamps may produce ozone. These technologies are more commonly used in domestic purifiers due to lower costs and relatively lenient environmental regulations in China regarding ozone emissions from air purifiers. In contrast, environmental regulations in Europe and America are very strict. Air purifiers manufactured in these regions are not allowed to produce ozone, meaning the aforementioned ozone-generating technologies are prohibited.

As for the hazards of ozone, they certainly exist. The extent of harm depends on the amount produced and the duration of exposure to this secondary pollution. A purifier may comply with national standards for ozone emission. However, compliance is one thing; the length of time spent in an ozone-containing room is another. The Chinese Ministry of Health sets the safe ozone concentration at 0.1 ppm, and labor protection regulations allow work for no more than 10 hours at this safe concentration. Long-term exposure in such an environment can lead to cumulative harm. Therefore, in the international air purifier industry, technologies that may produce ozone are no longer used.

The mainstream technology in the international air purification industry is pure physical filtration, which does not produce ozone. The California Air Resources Board (ARB) categorizes air purifiers into two types during certification: one uses physical filtration, typically generating no ozone; the other is classified as "other" technology, which may produce ozone but is tested to be below 0.05 ppm.

The "world no-ozone certification" promoted by many air purifier brands actually falls under the "other" category. The so-called "zero ozone" claim of such products merely means that the ozone concentration during operation meets the requirements of ARB's "other" category. The issue of ozone accumulation in enclosed spaces is unavoidable. Regarding ozone hazards, authoritative recognition states that ozone concentrations exceeding 0.03 ppm are highly harmful to humans. Long-term inhalation of ozone at such concentrations can lead to "sponge lung" due to ozone's strong oxidizing effect.

Principle and Advantages of Negative Ion Honeycomb Panels

• Principle of Negative Ion Generating Materials:

In 1989, Japanese scholar Kubo discovered and proposed that tourmaline (also known as toramaline or tourmaline) possesses a permanent spontaneous polarization effect. Tourmaline crystals have a potential difference, carry permanent charges, and exhibit piezoelectric and pyroelectric properties. Without requiring any energy source, they can release high concentrations of small particle size negative oxygen ions, emit far-infrared rays, shield electromagnetic radiation, and have excellent environmental functional attributes such as deodorization, sterilization, and water treatment. They do not produce ozone, contain no radioactive substances, and have no adverse effects on humans or the environment. Their lifespan is comparable to that of permanent magnetic materials, hence scientists refer to them as ecological negative ions.

• Principle of Small Particle Size Negative Ion Generation:

Unlike ionization-type negative ion generators where negative ions are generated from a single emission point,容易聚团导致负离子粒径过大, losing biological activity, the negative ions generated by this material are small in particle size because each nano-material acts as a single emission point. Dispersed over the large surface area of the honeycomb panel, they continuously release a large number of microscopically dispersed negative charges that combine with oxygen molecules in the air. This involves atomic-level charges directly combining with individual oxygen molecules, generating small particle size negative oxygen ions.

Combined with advanced nano-material purification and processing technology, the nano-tourmaline material sintered onto the negative ion honeycomb panel is processed to the nanoscale, resulting in more electron holes and greater negative ion generation.

To date, research has not found reports of adverse reactions or side effects from high concentrations of negative ions on the human body, nor is there a definitive conclusion on "what is the suitable negative oxygen ion concentration for humans." Based on this, we believe it is most scientific and reasonable to create indoor concentrations equivalent to the most livable and longevity-conducive natural environments.
