Abstract
There is provided a smart hair straightener including a pair of heating plates, a cylinder, a light sensor, a pressure sensor and a processor. The light sensor is used to detect rotation of the cylinder and to output a light detection signal. The pressure sensor is used to detect a pressure thereto from the cylinder and to output a pressure detection signal. The processor is used to control heating of the pair of heating plates according to the light detection signal and the pressure detection signal to adaptively adjust a temperature of the pair of heating plates corresponding to an amount of hair and a moving speed of hair.
Claims20
A hair straightener, comprising:
- a first pair of heating plates, configured to grasp hair therebetween;
- a heater;
- a first cylinder, arranged adjacent to the first pair of heating plates, and configured to be rotated by outer hair sliding over a first cylinder surface thereof upon the hair moving between the first pair of heating plates;
- a first pressure sensor, arranged opposite to the first cylinder, and configured to detect a pressure from the outer hair to the first cylinder and output a first pressure detection signal;
- and
- a processor, configured to control the heater to heat the first pair of heating plates according to the first pressure detection signal.
