The working principle of hair dryer negative ions
The negative ion hair dryer is mainly equipped with a negative ion generator and a semiconductor refrigeration device, so that
when the hair dryer works, it can produce negatively charged ion particles (produced by the negative ion generator) and water
vapor particles (produced by the semiconductor refrigeration device). It neutralizes the positive charge that often exists in the
hair, so as to smooth out the messy hair, make it fit and smooth, and can also eliminate static electricity.
Make hair smoother and easier to comb, and the styling effect is more ideal.
The negative ion generator is a device that generates negative ions in the air. The device processes the input DC or AC power by
the EMI processing circuit and the lightning protection circuit, and then through the pulse circuit, overvoltage and current limit;
high and low voltage isolation lines are upgraded to AC high voltage , And then get pure DC negative high voltage after
rectification and filtering through special grade electronic materials, connect the DC negative high voltage to the release tip made
of metal or carbon element, and use the tip DC.
High voltage produces high corona and emits a large number of electrons (e-) at a high speed, and electrons cannot exist in the
air for a long time (the life of electrons is onlynS level), and they are immediately captured by oxygen molecules (O2) in the air,
thereby generating Air anions. It is reported that there are more advanced anion release tips:
nanofullerene anion release tips, which can generate pure anions.
Air negative ions can be divided into light, medium and heavy ions according to their volume. The diameter of light ions is
about 0.000001cm, and they move faster in the electric field, which is 1～2 cm2/VS. In nature or ordinary environment, the
mobility is greater than 0.4 cm2/(V.s), which are small particle size negative ions. The diameter of heavy negative ions is about
0.0001cm, and it moves slowly in the electric field, only 0.0005 cm2/VS. In nature or in ordinary environments, the size and activity
of medium-
sized negative ions are between light and heavy ions. Among them, the small particle size negative ions have good biological
activity and are easy to penetrate the human blood-brain barrier and enter the human body to exert their biological effects.
The traditional negative ion generation technology cannot generate small particle size negative ions. Only the use of negative
ion converter technology and nanofullerene negative ion release technology can produce small particle size negative ions.
What is the role of negative ion hair dryer
Negative ions have health effects. In different regions, the number of negative ions in the air is quite large. Some people have
measured it. According to the number of negative ions contained in the air per cubic centimeter, there are about 1,000 in rural
areas, 4,000 on the beach, and near fountains and waterfalls. Above 5000. Because of the high content of negative ions in the air
in these places, people feel energetic. However, in some densely populated cities, the concentration of negative ions is relatively
low due to serious air pollution.
Some environmental departments have also tested it. In cities, there are hundreds of negative ions per cubic centimeter outdoors,
and there are even fewer indoors, no more than 1,000! Especially there are few negative ions next to TVs and computers. Studying
and working in this environment are often fatigued, which is not conducive to health.
Why do negative ions have health effects? Medical experts believe that there are the following three reasons through research.
First of all, in a living body, every cell is like a miniature battery with a potential difference of 50 to 90 millivolts inside and outside
of its membrane. It is the continuous charging and discharging of these "batteries". The body's nervous system can transmit visual
and auditory signals to the brain, or transmit instructions from the brain to various organs of the body.
The electrical activity of the body's tissues needs to be maintained by the continuous supplement of negative ions. Once the organism
is not supplemented with negative ions, it will affect normal physiological activities, causing chest tightness, dizziness, and even illness.
Secondly, since viruses that attack human cells are usually negatively charged, if human cells are also negatively charged, they will repel
each other due to the same sex. The virus loses its ability to attack living cells.
Finally, negative ions can enter the lungs through breathing, and directly stimulate various tissues of the human body, as well as the
interaction of nerve reflexes and body fluids, which have a neutralizing physiological health care effect on the human body.
