As consumers' requirements for makeup tools tend to be portable, intelligent and multi-functional, more and more technology-based makeup tools have emerged, electric heated eyelash curler is one of them. In order to avoid consumers being scalded during use, NTC thermistor needs to be placed as temperature monitoring and temperature control components.
At present, the electric heated eyelash curlers on the market generally have two temperature options, the low temperature option is 65°C, and the high temperature option is 85°C. When the user turns on the electric heated eyelash curler, the NTC thermistor will cooperate with the internal temperature measurement module to monitor the surrounding environment temperature and the working temperature of the product, when the temperature reaches the corresponding working temperature, the information will be fed back to the microprocessor, and the user will be prompted to finish heating by changing the color of the external prompt light. Due to the skin of eyes is thin and sensitive to temperature, the use of NTC thermistor can effectively assist user to use electric heated eyelash curler in a safe temperature range. Moreover, in order to avoid overheating of the shell and power consumption caused by long-term operation, the electric heated eyelash curler will also have an intelligent safety power-off function, and the time setting is generally 2~5 minutes. Using NTC thermistor to monitor real-time temperature, combined with temperature control module and power-off switch, when the electric heated eyelash curler is not used for a long time, it will automatically turn off and cool.
Due to the small size of the electric heated eyelash curler and the limited position of the internal circuit board, the preferred NTC thermistor is the IT series miniature insulated lead NTC thermistor of EXSENSE Electronics Technology Co., Ltd., which head is small in size and the lead can be bent, it is convenient for the overall product encapsulating. On the other hand, the electric heated eyelash curler fits the human body for use, it also requires high stability and sensitivity, so the high-precision miniature insulated lead NTC thermistor meets its selection requirements.
