Abstract: A hair straightening apparatus has two arms pivotably coupled at a hinge, and a central pack disposed between the first and second arms and coupled with the hair styling apparatus at the hinge on a hinge end of hair straightening apparatus. A locking mechanism is disposed within the central pack, wherein the locking mechanism includes a symmetrical, elongate lock arm disposed lengthwise within the central pack. The locking mechanism is selectively operable to lock the first and second arms in the closed position. The central pack defines a longitudinal axis, and the elongate lock arm is movable relative to the central pack between the first and second positions in parallel with the longitudinal axis defined by the central pack.

Abstract: A haircare appliance is provided for detecting a hair moisture content. The haircare appliance includes a processing element, at least one light emitting element emitting at least two wavelengths, and a sensor element, wherein the light emitting element is adapted to irradiate a portion of hair to be treated. The sensor element is adapted to receive a sensor reading from an acquisition region of the irradiated hair and generate a sensor signal dependent on the sensor reading and includes a spectral sensor element. The processing element is adapted to determine a moisture content of at least the irradiated portion of the hair from the sensor signal.

Abstract: Disclosed herein, a haircare appliance using wireless transmission of information and/or energy between the appliance's main body and an accessory. The appliance has a main body with a processing element, a communication element, and a blower for generating an airflow. The main body has an attachment region for connecting an accessory. The accessory has a sensor element to determine a sensor reading, a processing element, and a communication element. The accessory is selectively attachable to the main body at the attachment region, and when attached to the main body, it can receive the airflow from the blower, and discharge the received airflow towards the hair of a user. The main body and accessory have a communication connection for bidirectional communication. The bidirectional communication is a wireless communication connection, and energy for operating the sensor element is provided by the wireless communication and/or a separate wireless energy transfer connection.

Abstract: A hair care appliance is provided and includes a heater having a heating element, an airflow passage extending from an airflow inlet to an airflow outlet, and an air mover for moving airflow along the passage from the inlet to the outlet. The appliance further includes a thermal barrier at least partly surrounding the airflow passage so as to restrict heat transfer from the heater to an external surface of the appliance. The thermal barrier includes an inner wall proximal to the heater, an outer wall distal from the heater, and a sealed evacuated space defined between the inner and outer walls.

Abstract: A hair styling appliance includes elements moveable relative to each other, including a first arm and a second arm coupled together for reciprocal movement towards and away from each other, the first and second arms being arranged to receive hair within a region between each other. A sensor arrangement includes at least a first sensor component mounted to at least one of the elements and is configured to sense, using the first sensor component, a change in relative position of at least two of the elements. The sensor arrangement outputs a first signal indicative of an angle and/or a distance between the first arm and the second arm based on the sensed change in relative position.

Abstract: A haircare appliance has an air inlet, an air outlet, and an airflow generator for generating an airflow from the air inlet to the air outlet. The haircare appliance has a signal generator configured to generate a signal indicative of hair contacting the haircare appliance. The airflow generator includes a first operating mode in which the airflow generator generates airflow at a first flow rate, and a second operating mode in which the airflow generator generates airflow at a second flow rate greater than the first flow rate. The airflow generator is configured to operate in the first operating mode in the absence of the signal and in the second operating mode in the presence of the signal.
