Energy-efficient hair dryers supplier.Principle of negative ion hair dryer

　　The positive and negative ions of air can be divided into large, medium and small ions according to their mobility. Ionic 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. Groups of charged atoms, or molecules, close to the size of molecules, are small air ions. These small air ions have high velocities, collide with each other in the atmosphere, and continue to gather to form large ions or medium ions. Only small ions, or clumps of ions, can enter the organism. The small negative oxygen ion, or small negative oxygen ion group, has good biological activity.

　　The moving speed of ions under the action of electric field with unit strength (V/m) is called ionic mobility, which is an important parameter to distinguish the diameter of the measured ions. The smaller the diameter of air ions, the faster their migration rate. Ionic mobility is an important parameter to express the size of the measured ion. The velocity of ion motion is inversely proportional to the diameter of ion, and the mobility of ion is proportional to the velocity of ion motion, so the mobility of ion is negative proportional to the diameter of ion
