Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hair dryers, and more particularly to a hair dryer with multi-stage temperature regulation. Background Art
[0002] Traditional hair dryers usually only have limited temperature settings, such as cold air, low temperature and high temperature. The adjustment of these settings often relies on mechanical switches or simple circuit control, making it difficult to achieve precise temperature adjustment. With the advancement of technology, especially the rapid development of sensor technology, control technology and heating technology, the hair dryer industry has ushered in new changes. By presetting multiple temperature settings, users can choose the appropriate temperature according to their needs, thereby avoiding overheating and damaging the hair or failing to achieve the ideal drying effect. This technology not only improves the convenience of using hair dryers, but also greatly enhances their hair care effects.
[0003] Insufficient existing technology: Hair dryers that cannot adjust the temperature can usually only provide fixed high or low temperatures. Using too high a temperature for a long time will directly cause the moisture in the hair to evaporate quickly, making the hair dry and brittle, and even causing heat damage such as split ends and rough hair. On the other hand, using too low a temperature may not effectively dry the hair, prolonging the drying time and also placing unnecessary burden on the hair. For hair dryers without a temperature display, users can only rely on preset gears (such as cold air, warm air, and hot air) to adjust the temperature. However, these gears often cannot provide precise temperature control. This may result in users being unable to accurately adjust the temperature according to their hair quality, hair volume or current needs during use, which may cause hair overheating damage or poor drying effect.

[0027] The working principle of the present invention is as follows: the user changes the resistance of the potentiometer by rotating the adjustment wheel 301, thereby controlling the size of the current in the circuit.

The greater the current, the more the heating wire 102 heats up, and the higher the temperature of the hot air generated. Conversely, the temperature is lower. The temperature sensor inside the hair dryer monitors the air outlet temperature in real time and transmits the signal to the circuit board 203. After processing, the circuit board 203 displays the current temperature in real time through the temperature display screen 202. The motor 103 drives the fan 104 to rotate and generate airflow. When the heating wire 102 is energized and heated, the airflow passes through the heating wire 102 and is heated into hot air. If the heating wire 102 is not energized, cold air is blown out. The user can adjust the temperature as needed to achieve multi-level temperature regulation.
