As early as 2007, james dyson, the founder of Dyson, applied for the patent of bladeless fan all over the world and named it AirAmplifier? Air multiplication technology, ultrasonic brushless motor sucks air into the bottom of the handle through the filter screen, and then the temperature can be raised to the required temperature through the heating coil, and finally it is pushed to the hollow circular tube, similar to the technical principle in jet engine and automobile turbocharging. The Kangda effect is said to be able to eject three times the powerful airflow.
Sensory disorder? Blowers provide powerful and stable wind power. You should know that the engine speed of a jet plane is usually around 17000 rpm, the turbocharger speed of a six-cylinder car is around 80000 rpm, and Dyson's V9 digital motor has a high-speed 1 13 impeller, which is said to be only 27mm wide.
Dyson hair dryer adopts ultrasonic digital motor. In order to reduce the vibration of the handle, the V9 brushless DC motor is installed in a rubber sleeve. In order to reduce noise, the fuselage handle also uses four pieces of high-density flame-retardant noise-reducing cotton.
The 13 impeller installed on the motor shaft is completed by a five-axis milling machine, which may be one of the most expensive parts in the whole assembly.
The electric heating wire of the hair dryer is covered with mica insulation sleeve, which can prevent the plastic shell from overheating and scalding the user's hands. You can also see the black sliding power switch and the key switch of "one-button air conditioning".
