Negative ion module is a device that can generate negative ions to improve air quality and eliminate odors. The following is the working principle and related applications of negative ion modules:

working principle:
Generation of negative ions: Ion generators generate negative ions through physical or chemical methods. This usually involves using high-voltage diodes, capacitor rectification and filtering to raise low voltage to DC negative high voltage, and then using tip discharge to generate high corona, thereby generating negative ions.
Transport of negative ions: The generated negative ions are transported to indoor air through electric fields, wind fields, or so-called ion winds. This step is a key part of achieving purification of pollutants in the air.
Release of negative ions: After combining with particulate matter or pollutants in the air, negative ions can be released through sedimentation or captured by filters, achieving the goal of purifying the air.

Related applications:
Air purification: Negative ion modules are mainly used for air purification. They can adsorb and decompose bacteria, viruses, smoke, and other harmful substances in the air, improve indoor air quality, and act as ozone generators.
Smoke and dust removal: Negative ions can effectively eliminate smoke and dust, making the air fresher.
Strengthening the moisture retention of hair: Negative ion generators can also be used in the field of beauty, such as enhancing the moisture retention of hair, making it softer and smoother.
In summary, negative ion modules effectively improve indoor air quality by generating, transmitting, and releasing negative ions, and have a wide range of applications in daily life.
