Thermal Devices for Hair Moisture Management

Constant temperature hair dryer with a temperature sensor that accurately maintains a consistent temperature when blowing hair to prevent damage and discomfort. The hair dryer has a temperature sensor outside the handle that monitors the surface temperature of the hair as it blows. This feedback is used by the control board to intelligently adjust the heating and fan settings to maintain a set temperature. By measuring hair surface temperature instead of just air outlet temperature, it compensates for variations due to distance and provides more accurate control.

Hair dryer with a drying method that reduces heat damage to hair and scalp. The hair dryer has multiple drying modes with different temperature thresholds. When the user selects a mode, the dryer starts blowing air at the lowest threshold. This allows scalp drying without excessive heat. After scalp drying, the dryer switches to a higher temperature mode to dry the hair. This prevents half-drying of the scalp, which can cause damage. The scalp-first drying method reduces heat exposure to the scalp and hair.

Intelligent hair dryer that automatically adjusts airflow and temperature to prevent overheating and shutdown. The dryer has a temperature sensor at the outlet, a controller, and a heating module with multiple stages. The controller compares the outlet temperature to limits. If above max, it reduces speed and increases lower stage heating. If below min, it increases speed and lower stage heating. This allows steady temperature without shutdowns. A cooler in the outlet further regulates temp.

Intelligent temperature adjustment hair dryer that allows precise control of the outlet air temperature to prevent damage to hair. The hair dryer has a temperature sensor at the air outlet that feeds back the temperature to the main control board. A rotary resistance is used to set the temperature threshold. When the sensor detects a lower temperature, the relay closes and the heating wire works. When the sensor detects a higher temperature, the relay disconnects and the heating wire stops. This reciprocating cycle keeps the outlet temperature within a range for quick drying without damaging hair. A display shows the sensor and set temperatures.
