Hair dryer, a seemingly ordinary household appliance owned by every household, has hardly changed much in its core technology for a long time. However, it was not until a brand named Dyson appeared in recent years that it was redefined in a subversive way. Dyson supersonic hair dryer is not only a tool to dry hair, but also a profound innovation of traditional engineering and aerodynamics.

Its revolutionary core lies in its unique Dyson digital motor V9. This motor is small and light, but it has amazing speed. It can reach as high as 110,000 revolutions per minute, which is several times that of traditional motors. This high-speed operation is not simply the pursuit of speed, but to drive a brand-new wind power system. The traditional hair dryer uses a large motor, which heats the air through the propeller and blows it out, which is noisy and the wind is scattered. Dyson's motor is skillfully placed in the handle of the blower, which not only changes the center of gravity of the equipment, makes it more ergonomic, but also provides greater freedom for air duct design.

The high-speed airflow generated by the motor is inhaled and accelerated by the unique Air Multiplier™ technology, and finally ejected at high pressure and high speed. The head of the blower does not spray air directly, but sprays powerful high-pressure airflow through the annular slit. When these air streams pass through the slits, they will induce the surrounding air to be sucked in at three times the speed and ejected together, forming a strong and concentrated air stream. This airflow is not only strong, but also the temperature is precisely controlled, which is the secret of Dyson hair dryer to dry hair quickly. It does not "dry" the hair through excessive temperature, but quickly blows away the water droplets on the hair through strong airflow, thus reducing the damage of heat to the hair.

In addition to the wind system, another key innovation of Dyson hair dryer lies in its intelligent temperature control technology. It has a built-in miniature glass bead thermistor, which can monitor the air outlet temperature for more than 40 times per second. When the temperature exceeds the set safe range, it will immediately send instructions to the microprocessor to automatically adjust the power of the heating element to ensure that the blown air temperature is always at a healthy and constant level. This technology effectively avoids the problem that the traditional hair dryer damages the hair quality due to overheating, so that users can enjoy fast hair drying while protecting the luster and health of their hair.

From appearance design to internal structure, Dyson supersonic hair dryer represents a thorough rethinking of traditional products. It perfectly combines the complex principles of fluid mechanics, precise electronic control system and avant-garde industrial design, and promotes a daily necessities to a brand-new technical height. It is not only a hair dryer, but also an answer to the question "How to make products more efficient, smarter and healthier".
