A smart nozzle system for a hair dryer includes a proximity detection circuit, a temperature sensing circuit, a speed detection circuit, and a rotating nozzle vane, among other features. The nozzle includes a microcontroller and a wireless communication module to interface with an external computing device via an application. Also included is a camera, a timer, a fluid dispenser, and a therapeutic UV light. The power supply can be a dynamo powered by air flowing through the nozzle. The nozzle can be an add-on to existing hair dryers or can be integral with a hair dryer system.

A wireless negative ion hair care cap comprises an air permeable pliable cover body, at an opening thereof is disposed an elastic band for the wireless negative ion hair care cap to fit tightly around a human head, on the inner periphery thereof are disposed electric heating elements and at least a negative ion generator, and on the outer periphery thereof are disposed a controller having an electric circuit and a holding for a battery to be placed therein. The controller is to set up a time and temperature and to control the electric heating elements and negative ion generator for releasing heat and negative ions. The generated heat and negative ions are transferred to an inside of the pliable cover body and are evenly distributed therein to apply heat to the hair on the human head.

In a hair styling device (20) having a two-dimensional array (21) of elements to bring hair at a styling temperature, the elements produce optical radiation energy. The elements may include one or more LEDs, and preferably a plurality of LEDs, in which case the LEDS are driven in clusters that may be of mutually different shapes and sizes. The hair styling device (20) further comprises sensors to obtain an areal light absorption measurement opposed to the two-dimensional array of elements, and a control unit for individually controlling the elements in dependence of the measurement. The sensors may be arranged for measuring an areal light density profile of a whole treatment area. The hair styling device may radiate hair from two sides, both of which includes an areal light absorption measurement. The sensors may include LEDs that do not produce light.

A hair dryer and dryer system mountable between a pair of wall panels includes a hollow cylindrical housing having open inlet and outlet ends and a passageway extending therebetween, a group of co-operative components supported by the housing in communication with its passageway and co-operable to induce an inflow of unheated air into the housing open inlet end and an outflow of heated air from the housing open outlet end, a threadably adjustable annular coupler at the housing open inlet end, and an annular flange at the housing open outlet end. The annular coupler and annular flange together enable the housing to be disposed between and clamped respectively to the wall panels with the open inlet and outlet ends of the housing respectively occupying the first and second openings of the wall panels.

A hair iron according to the present disclosure is configured to hold hair in a state in which a first hair holding surface and a second hair holding surface face each other. A first hair holder includes ion outlets configured to release ions generated by a discharge device. The discharge device includes a first electrode having a plurality of discharge electrodes. The first electrode includes an electrode body having a plate shape. The discharge electrodes are disposed on a side portion e end of the electrode body as the electrode body is viewed in a thickness direction thereof. The discharge electrodes include two types of discharge electrodes of which shapes are different from each other.

A dryer includes a plurality of first electronic parts including a fan and a heater, a first battery to supply power to the first electronic parts, and a first controller to control power of the first battery. The first controller detects a charging ratio of the first battery, enters a first power saving mode if the charging ratio is a threshold charging ratio or less, and limits power supplied to at least one of the plurality of first electronic parts. A holder for holding the dryer includes a plurality of second electronic parts including a plurality of contact terminals, a second battery to supply power to the second electronic parts, and a second controller to detect a charging ratio of the second battery and enter a second power saving mode to limit power supplied to at least one of the plurality of second electronic parts.
