Abstract: A hair curling device comprises a grip (6), an electric heating element (2) installed on the grip (6), an ion generator (4), a three-dimensional control interface (1) with a button (33), and a display screen (5). The three-dimensional control interface (1) simultaneously connects to and controls the electrothermal element (2), the ion generator (4) and the display screen (5), and adjusts at least one functional element through the button (33) so as to adjust different functions of the hair curling device, including temperature adjustment of the electrothermal element (2) and adjustment of the ion generator (4).
