NTC temperature sensor for curlers.Human Body Infrared Temperature Sensor

　　A curler is an electronic product for curling hair, which mainly includes a handle and a heating component. The handle is used for users to hold and contains control circuits. Under the control of the control circuit, the heating component is energized to generate a heat source for curling hair.

　　The curler is composed of a handle component, a cylindrical metal sleeve, an external clamping component of a pivot connected cylindrical metal sleeve, and a heating core component installed inside the metal sleeve and electrically connected to the handle component; The width of the cylindrical metal sleeve is smaller than that of the handle component; The handle component is internally equipped with a temperature control circuit board, and the heating core component is connected to the temperature control circuit board NTC temperature sensor and the heating mica board, a heat transfer mica board tightly connected to the surface of the heating mica board, and a heat transfer cloud motherboard heat transfer plate; The heating mica board includes a mica substrate and a heating wire wound on the mica substrate, which is electrically connected to the temperature control circuit board; The NTC temperature sensor is located between the heat transfer plate and the heat transfer cloud motherboard.
