The core differences among the three types of temperature sensors
1. Basic Protection Type (Suitable for most traditional hair dryers)
Main technical/sensor types: NTC thermistor, temperature control fuse
Core functions and purposes: Prevent overheating of the body or the outlet, ensuring basic safety.
Temperature measurement objects: Internal heating elements or air from the outlet.
Features: Low cost, basic safety feature.
2. Precise Temperature Control Type (for mid-range/advanced hair dryers)
Main technical/sensor types: Glass bead temperature and humidity sensor, dual NTC sensors
Core functions and purposes: Maintain a constant airflow temperature, enhance the comfort of drying hair.
Temperature measurement targets: Outflow temperature, or simultaneously monitor outflow temperature and ambient temperature.
Features: Achieve multi-level constant temperature blowing, providing a better experience.
3. Hair Temperature Tracking Type (for high-end/ flagship products)
Main Technologies/Sensor Types: Infrared temperature sensor, multi-sensor fusion module
Core Functions and Purposes: Directly monitor hair temperature and dynamically adjust air temperature to achieve intelligent hair care.
Temperature Measurement Object: Surface temperature of the hair.
Features: Cutting-edge technology, can prevent hair heat damage, and has high dry hair efficiency.
Key Functions and Technological Trends
Regardless of the type of sensor, the core function is to strike a balance between dry hair efficiency and prevention of heat damage.
Preventing overheating damage: When hair is exposed to temperatures above 60℃ for a long time, the proteins will denature, causing damage to the hair scales and making the hair dry and prone to breakage.
Enhancing dry hair efficiency: Intelligent hair dryers (such as Tanque Mowman 2.0) can quickly dry the hair in the initial stage using a higher temperature (still below 60℃), and then reduce the temperature to enter the hair care stage later.
The future technological trend is the deep integration of “sensors + algorithms”. For instance, existing solutions have integrated infrared temperature-sensing sensors andToF ranging sensors into a single module. This not only enables real-time monitoring of hair temperature but also allows for sensing the distance between a hair dryer and the hair. Through algorithms, it achieves more precise “dynamic following” style hair-drying.
