A hair curling device includes a handle, a styling body connected with the handle, and a transmission mechanism disposed between the handle and the styling body. The styling body includes an outer shell for hair to be wound around. The outer shell is provided with an air outlet hole. The styling body further includes a hair clipping gap arranged on an inner side of the outer shell. Two sides of the hair clipping gap are provided with a clipping member, respectively. At least one of the clipping members is connected to the transmission mechanism. The transmission mechanism includes an inclined surface matching structure to realize expansion or reverse contraction of the hair clipping gap.

A portable curling iron device, equipped with an internal rechargeable battery, configured for the curling of hair of a user while on-the-go. The device exhibits a textured, heat resistant handle, at least one heating coil disposed within a curling head, and a USB port. Charging of the rechargeable battery is facilitated via a USB cable disposed in communication with a power source and the USB port. A heat-resistant carrying case bundled with the device enables the user to immediately store the device after use without concern for burning or damaging adjacent items. The device has a small form factor, ensuring it may easily be stored within a purse, bag, glove compartment, or similar small space.

A heater including a ceramic heater element and ceramic heat sink whereby the ceramic heater element and the ceramic heat sink are both formed from a plurality of layers of tape cast ceramic material. The ceramic heater element may be generally planar and extends within a first plane. The ceramic heat sink may extend in a second plane which is orthogonal to the first plane. The ceramic heat sink may include a plurality of fins which may be discrete. The layers of the ceramic heater element may be orientated orthogonal to the layers of the ceramic heat sink. The ceramic heater element may comprise a conductive track which may be surface mounted to a distal side of the ceramic heater element than the ceramic heat sink or embedded within the ceramic heater element.

A hairstyling apparatus is provided, the apparatus including: a barrel defining a hairstyling surface and a central longitudinal axis, wherein the barrel has a first proximal end and a second distal end; a heating element in thermal communication with the barrel; and a rotating member in rotating communication with the proximal end of the barrel which rotates around the central axis of the barrel, the rotating member including a rotating plate that surrounds the proximal end of the barrel and an axially extending tab from the rotating plate along a longitudinal length of the hairstyling surface over at least a portion of longitudinal length of the hairstyling surface; wherein the rotating member includes a comb member, extending from the rotating member (such as the rotating sleeve/collar) which is attached or assembled to the tab and comprises a plurality of comb teeth arranged along the longitudinal length of the hairstyling surface.

A hairstyling device is provided. The hairstyling device includes a heatable hair contact member having a hair-contactable surface, the hair contact member being operable to apply heat to hair via the hair-contactable surface. The hairstyling device includes an inertial measurement unit, IMU, configured to output signals dependent on movement of the hair contact member. The hairstyling device includes a controller configured to receive a signal from the IMU indicating movement of the hair contact member along a tress of hair between a first end of the tress and a second end of the tress, process the received signal to determine a speed of the hair contact member, and control heating of the hair contact member based on the determined speed.
