    摘要: A hair care device comprises a body having an output to supply heated air, and at least two different attachments that can be attached to the output of the body. In accordance with the invention, the body comprises a detector for detecting whether one of the attachments is attached to the body, and if so, which attachment is attached to the body, to provide a detection result, and a controller for controlling the supply of heated air in dependence on the detection result. According to the invention, each attachment has at least one magnet at predefined positions at an attachment contact area of the attachment for contacting the body, the at least two attachments having mutually different magnet configurations, and the detector comprises a plurality of Hall effect sensors at predefined positions (▪) at a body contact area for contacting a selected one of the attachments.

    摘要: A hair straightener (HS) comprises a heating unit (HU) for heating hair while exercising a pressure on the hair, a temperature sensor (TS) for measuring a temperature of the heated hair to obtain a measured temperature, and a pressure adjustment unit (PAU) for adjusting the pressure exercised by the heating unit (HU) on the hair, in dependence on the measured temperature. The heating unit (HU) may comprise a pair of heating plates (HP1, HP2) between which hair is clamped, and the pressure adjustment unit (PAU) may be arranged for changing a distance between the heating plates (HP1, HP2). The pressure adjustment unit (PAU) may comprise a motor-operated push tool (W, C) for increasing the distance between the heating plates (HP1, HP2) when the measured temperature exceeds a first threshold temperature. The hair straightener (HS) may comprise a pair of hinged arms (A1, A2) each provided with a respective one of the heating plates (HP1, HP2). The pressure adjustment unit (PAU) may comprise a motor-operated pull tool (W, S), for decreasing a distance between the hinged arms (A1, A2) when the measured temperature falls below a second threshold temperature, whereby the distance between the heating plates (HP1, HP2) is reduced.
