  • the control unit may be configured to authorize the supply of steam, and/or to automatically supply steam to the steam outlet, by the steam supply system at least the sensor detects a magnetic field.
  • the motion sensor may comprise at least two microswitches arranged on either side of the axis of rotation and configured to be actuated when the feeler is moving, for example when it pivots about the axis of rotation by a threshold angle.
  • the threshold angle may be a function of the position of the microswitches with respect to the feeler.
  • the control unit may be configured to authorize the supply of steam, and/or to automatically supply steam to the steam outlet, by the steam supply system when at least one of the two microswitches is actuated.
  • the device may comprise a gripping detector, in particular arranged at the handle of the device, to detect the gripping by the user of the device.
  • the control unit may be configured to authorize the supply of steam, and/or to automatically supply steam to the steam outlet, by the supply system when at least two conditions are met, namely, on the one hand, the contact or proximity condition verified from information generated by the contact or proximity detector and, on the other hand, a gripping condition verified from information generated by the gripping detector.
  • the gripping detector may be an infrared, inductive, capacitive or sound detector, or a microswitch.
  • the gripping condition detected may be information on positive detection of the gripping by the user generated by the gripping detector.
  • the control unit may be configured to prevent the supply of steam by the steam supply system when the device is switched off and before the hair contact or proximity condition is met after switching on the device.
