Abstract: A hair iron comprising an ion generator that generates ions comprises a slotted nozzle in communication with the ion generator for generating an ion curtain projecting from at least one side of a body of the hair iron, alongside and substantially parallel to a longitudinal edge of the heating element that contacts the hair in use.

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).

Abstract: A hair straightener with a clip structure comprises electric heating elements (2), an ion generator (4), a three-dimensional control interface (1) having a button (33), a display screen (5), a linking member (6), an upper arm (7) and a lower arm (8). The upper arm (7) and the lower arm (8) are linked with each other through the linking member (6), so as to form the clip structure. The three-dimensional control interface (1) simultaneously connects with and controls other different functional elements of the hair straightener, and adjusts at least one functional element through the button (33), so as to adjust different functions of the hair straightener, including the temperature adjustment of the electric heating elements (2) and the adjustment of the ion generator (4).

Abstract: A diffuser for a handheld electric hairdryer, includes a base from which a plurality of fingers extend, each finger having a longitudinal through-passage through which hot air passes from the base. There is attached to the base a thermal-capacitance element to moderate changes in temperature of air exhausted through the diffuser.
