The invention relates to a hair styling appliance (100, 100′, 100″) comprising at least one heater (103, 104) having a plurality of heating zones (Z1-Z5). The heating zones are independently operable arranged along the length of the heater. The sequential arrangement of the independently operable heating zones helps to improve the thermal control of the hair styling appliance. The hair styling appliance may be a hair straightener, curling tong, curling wand or a crimping iron.

A hair straightener and its integrated switch for control and display are disclosed. The hair straightener comprises first and second clamping plate parts and the integrated switch for control and display arranged on an inner side of the second clamping plate part. The integrated switch for control and display comprises a temperature control knob assembly for regulating and controlling temperature, a display button assembly for displaying the temperature and turning on or off a power supply, and a control motherboard for digital display and electrical control. The temperature control knob assembly and the display button assembly are installed on the control motherboard. The temperature display, control and regulation functions, and the power supply switching on and off functions are centralized on the same switch key, such that the temperature can be controlled and regulated conveniently when operated by one hand and the visual information can be obtained without obstacles.

A hair styling appliance for dual supply voltage operation is described comprising a body having at least one arm bearing a hair styling heater (560), wherein the hair styling heater comprises one or more heater electrodes (630,632,634,636) for heating the hair styling heater. A first power input is connectable to a battery power source (564) and a second power input is connectable to a mains powered source (561). The first power input and the second power input are each coupled to at least one of the one or more heater electrodes. Such a hair styling appliance is useable for styling when coupled to the mains powered source and when coupled to the battery power source increasing the versatility of the appliance.

A rechargeable hair styling tool may be plugged into an electrical outlet to enable charging of each battery and operation of the hair styling tool. Electronics of the hair styling tool may enable it to alternately operate under power from the battery or batteries (i.e., stored power) while the hair styling tool is unplugged from an electrical outlet (e.g., a wall socket, etc.) and under power of an external source of electricity while the hair styling tool is plugged into the electrical outlet. Each heating element of such a rechargeable hair styling tool may be heated when the hair styling tool is plugged in and, once each heating element has been heated to a sufficient temperature, continue to function under power supplied by the battery or batteries of the rechargeable hair styling tool.

The present invention relates to a multi-functional hair-styling thermal treatment beauty device, which continuously rotates, in a clockwise or counterclockwise direction, a hair-styling part for holding hair while holding body part is held or can open an upper rotary body of the hair-styling part so as to enable hair styling to be easily performed. according to circumstances, and forms continuous grounding structure so as to enable power to be continuously supplied to a heating plate mounted inside the hair-styling part capable of continuously rotating, so that the heated state of the heating plate, caused by the heating of a current, is continuously maintained even during continuous rotation, and thus various hair styles can be more effectively created by the hair-styling part, so that hair styling is easily performed according to circumstances, and operation fatigue is reduced so that use convenience can. be improved.

A hair styling iron includes a housing, a mandrel extending longitudinally from the housing, the mandrel having a proximal end adjacent to the housing, and a distal end opposite the proximal end, and a plurality of light emitting elements within the mandrel. The plurality of light emitting elements are light emitting diodes that emit light having a wavelength between about 620 to about 750 nm. A cross-sectional area of the mandrel at the proximal end is greater than the cross-sectional area of the mandrel at the distal end.
