User hair placed atop the layer of glass is styled using heat passing from the film layer through the layer of glass. The film layer may comprise an ink film layer, a resistive ink film layer, a layer of Polymer Thick Film (PTF) ink, and/or a nano ink layer.

A hair treatment device includes a first and a second arm, movable in relation to each other, which can be opened to introduce a strand of hair between them and closed to treat the strand of hair, a first and second contact surfaces respectively supported by the first and second arms, arranged facing each other, with at least one of the contact surfaces being heated, at least the first arm having at least one first piece supporting the first contact surface, a sealing element including a central window arranged such that it extends at least partially around the first contact surface between the latter and the first supporting piece,
wherein the sealing element includes at least one opening that is distinct from the central window and the first supporting piece and the first contact surface come into contact with each other through the at least one opening.

A connecting-fixing structure, used for detachably connecting a main body of an electrical appliance with a power cord, includes a connection end, a locking member, and a rotating sleeve. The locking member includes a supporting shaft and a locking portion which rotates by the supporting shall as a fulcrum. A locking fitting portion is disposed on the tail end of the power cord and adapted to the locking portion. Furthermore, a rotating sleeve is rotatably sleeved on the connection end, an inner wall of the rotating sleeve has a driving part, and the rotating sleeve rotates to drive the driving part to further drive the locking portion to rotate, thereby locking the locking portion or unlocking the locking portion from the locking fitting portion. The power cord can be disassembled and assembled only by rotating the rotating sleeve, and the operation is convenient, and the structure is simple.

A hair styling iron with a built-in Bluetooth for using functionalities of the built-in Bluetooth while using the hair styling iron at high temperature is disclosed. The disclosed hair styling iron includes a circuit board with a built-in Bluetooth, a speaker, control button(s) and a rechargeable battery. Once the hair styling iron is paired with another Bluetooth device, the user can control certain function(s) of the connected Bluetooth device and also stream audio media from the connected Bluetooth device. The rechargeable battery provides power to the speaker and the circuit board when the hair styling iron is not connected to an alternative current (AC) power source.

The invention relates to an assembly having a refill and an appliance designed for using the refill, the appliance having an insertion guide along which the refill travels, the refill having an element that serves as a use memory and the accommodating structure having a relief that acts on said element when the refill is fitted on the appliance for the first time, so as to cause it to pass from an inactive configuration to an active configuration, the accommodating structure having a locking member disposed to as to intercept said element when the latter is in the active configuration, while the refill is being fitted in and removed from the accommodating structure, the locking member can be passed over by said element in the direction of removal of the refill and such that the locking member prevents said element from passing in the direction of insertion of the refill.

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.

The invention relates to a cosmetic product refill (20) for a hair treatment device (1), comprising an applicator member that is saturated with liquid cosmetic product, with a degree of filling less than or equal to 90%, preferably less than or equal to 80%>, more preferably less than or equal to 70%, the degree of filling being defined as the ratio of the mass of cosmetic product in the applicator member divided by the maximum mass of cosmetic product with which the applicator member can be saturated.

This invention relates to a hair styling device, a hair styling method, and a drive system suitable for use in the hair styling device. The invention relates in particular to a hair styling device (10; 210) for imparting a wave to a section of hair (36) without clamping the section of hair in the wave form. The device has a first forming member (24) and a second forming member (24) with a hair-receiving region (38) between the forming members. A driving member (20; 120) is movable relative to the first forming member and the second forming member to deform the section of hair in the hair-receiving region. The driving member (20; 120) undertakes a two-stage movement as it deforms the section of hair, the driving member in a first stage being movable in a first direction (D1) to drive the section of hair (36) into the hair-receiving region, the driving member (20; 120) in a second stage being movable in a second direction (D2), the second direction being at an angle to the first direction whereby in use to further move the section of hair in the hair-receiving region (38).
