Traditional hair dryers are mainly composed of nozzles, heating elements, motors, fans, handles, PCBA control boards, switches, etc.
The working principle of Home Hair Dryer is that the motor drives the fan to rotate. When the fan rotates, air is drawn in from the inlet, and the resulting centrifugal airflow is blown out through the nozzle; When air passes through, the hair dryer switch is turned to the hot air mode, and the electric heating element will be powered on to heat and blow out hot air; Turn the switch to the cold air mode, the electric heating element is not powered, and cold air is blown out; Hair dryers are used to achieve rapid drying and styling of hair.
Traditional hair dryers use high temperatures and strong winds to quickly dry hair, but this method can easily disrupt the natural moisture balance of hair, leading to dryness and frizz. Therefore, negative ion hair dryers have emerged to effectively solve this problem. The negative ion hair dryer has an additional negative ion generator, which mainly consists of a high-voltage generator and a negative ion emitter.
The high-voltage generator generates a high-voltage electric field, which ionizes oxygen and water molecules in the air to produce negative ions. These negative ions are released into the air through the negative ion emitter and neutralize the positive charges on the hair, achieving the effect of reducing static electricity and smoothing hair.
How do engineers design a hair dryer? What are the commonly used electronic components or chip solutions? We have compiled a BOM table for the PCBA board of home hair dryers for reference in home hair dryer design.
