Abstract: The present disclosure relates to a hair iron, the hair iron including a first body and a second body, a first cover, a second cover, a first heater, a second heater, and a cartridge, whereby damage to user hair and a safety accident can be prevented by styling the user hair at a relatively lower temperature, and insufficient hair styling caused by low temperature can be effectively complemented by coating hair treatment material on the user hair through evaporation of the hair treatment material.

Abstract: The invention provides a hydrocarbon-fueled device for heating and dispensing a volatile substance, such as an insect repellent. The device provides a long-lasting 48-hour fuel system, multiple fuel canisters that can be exchanged without interrupting the operation of the device, an illuminated indicator that provides a visible indication of the operating state of the device from any viewing angle, and a flame-extinguishing safety lid. During the warm-up phase, the indicator indicates this state by pulsing. Once the device reaches operating temperature, the indicator emits a steady light, indicating proper operation. In the event that the device cools below the operating temperature, the light will pulse, alerting the user to check the flame and/or fuel supply. The user can initiate complete, properly-controlled operation of all functions of the device via the operation of a single on-off switch.

Abstract: A system and method for an intelligent hair drying/styling apparatus with user information transmission and storage capabilities is herein provided. The hair drying/styling apparatus houses a control circuit board and an infrared or temperature sensor (or camera) in order detect an individual's hair condition moisture level to determine a user specific, customizable dryer setting. The information detected by the sensor is stored locally, on a proximal Internet-enabled device, or on a remote or cloud-based server and accessed by the hair drying/styling apparatus through a wireless local area network connectivity function. Accordingly, a user's hair temperature-drying profile may be stored and later recalled to provide optimal hair styling setting customized for that user. This innovation will enable any number of hair professionals and or end consumers to improve styling and dry time.

Abstract: A dual gas and AC electric hair styler comprises: a heater, a housing, and a control member movably disposed in the housing. One end of the control member is exposed out of the housing and another end of the control member is inserted in the housing to connect a linkage device of the heater. The linkage device includes a guiding member. A gas supply and an electric power supply are selectively inserted in the housing to the heater and each have a valve which is pressed to achieve connection. The axial movement of the control member causes axial movements of the linkage device and the guiding member to affect connection of the gas and the electric power supply to the heater. The hair styler can be powered by gas or electric power, and the switching of gas and electric power supplies can be done by the control member.

Abstract: A hair styling device includes a styling rod and a handle connected with the styling rod, which features a holding device and a pivoting cap connected to the holding device. The cap can be pivoted between an opening and closing position and serves to close the housing for the gas cartridge. The inside of the cap features in the area of its free end contact parts, which are designed to exert, upon closure of the cap, a displacement force on the gas cartridge in axial direction of the device. As a result, by closing the cap, the gas cartridge is moved directly into operating position during which a needle valve is inserted in a valve of the gas cartridge by displacing the gas cartridge. In addition, in the area of its linkage to the holding device, the cap features a clamp which, upon opening of the cap, exerts an axial displacement force on the gas cartridge in longitudinal direction of the device toward the handle's end of the hair styling device and thus brings it into a position of removal.

Abstract: A portable catalytically heatable appliance is provided. The appliance includes a catalyst support structure to flamelessly combust liquid or gaseous fuel and thereby provide a lower temperature heat source than a heat source that combusts fuel via flame. The fuel is ignited inside the catalytic support structure by a spark electrode. The ignition of the fuel inside the structure obviates the need for separate flame arresters. The ignition system includes a piezoelectric device that causes a voltage potential to form between the electrode and the catalytic support structure. A spark jumps from the electrode to an interior surface of the structure and ignites the fuel inside the structure, causing a flame to propagate. The flame heats the catalytic structure to an activation temperature, after which the fuel is combusted flamelessly on the surface of the catalytic structure.

Abstract: A cordless, hydrocarbon fuel powered hairdryer. The invention incorporates a novel electronic control system which evaluates the thermal and electrical conditions within the hairdryer during its operation. Two fuel flow valves are provided. The first fuel flow valve is mechanically actuated and opens and closes the valve in the hydrocarbon fuel cartridge. The second fuel flow valve is a solenoid valve that cannot open without a predetermined voltage being supplied. Application of the predetermined voltage will allow gas to flow through this second valve and into the area where the fuel is ignited. Only when both valves (the mechanical and the solenoid) are open, can fuel flow. A microcontroller monitors the temperature conditions in the combustion area, and controls system conditions such as power to the solenoid valve and to the fan motor to prevent uncombusted gas from building up and presenting a safety hazard.

Abstract: A moldable central body for use in a catalytic burner has a generally rotational symmetry about a longitudinal axis. It provides a cover retaining surface for the cover of the unit; furnishes the bayonet pin for receiving the cover; carries spacers positioning itself within the outer casing; holds the wave member in position; holds the stem support in position, which, in turn, holds the valve seat; provides a pivot hole for the spoon pivot for a curling iron; is a seat and shoulder for the diaphragm; provides an inner surface to hold alignment members for the control stem; holds the seat for the spring for the control stem; and provides a barrel retaining surface for a curling iron barrel. The control stem of a regulation element moves axially within the central body.The central body can be molded of plastic as a single integral piece. Since this central body serves so many functions and, yet, can be molded as a single integral piece, it reduces the cost of manufacture of the burner of this invention.

Abstract: A butane burner for personal care appliances includes a receptacle at one end for a gas canister. Upon insertion of a canister, a probe presses against the canister valve, opening it; and it thereafter remains open. Gas then flows to the input end of the control stem and, depending upon the longitudinal positioning of the control stem, flows into the stem through a gas inlet orifice in one side of the stem and travels in a channel within the stem to an outlet orifice at the other end. There it enters a Venturi, is mixed with air, passes from there through a mixing chamber and to a burning chamber within the barrel of the curling iron. The catalytic burner is located in the burning chamber. The control stem is spring-pressed in a direction to keep the gas inlet orifice normally in the open position. Movement of the control stem a slight distance in a direction away from the canister and toward the Venturi blocks the gas inlet orifice and stops gas flow.
