A portable biometric lighter device (100) generally involving a control unit (210), a biometric sensor, such as a fingerprint sensor (140), wherein the biometric sensor is configured to scan a biometric data of a user and is operably coupled to the control unit (210), and an ignition element, wherein the ignition element is activated by the control unit (210) upon a match of the scanned biometric data of the user and a biometric data of an authorized user that is stored in a memory device.

A cooking appliance muffle for a cooking appliance includes: a cooking chamber with a cooking chamber opening tightly closeable by a door of the cooking appliance, at least one cooking chamber wall bounding the cooking chamber. The cooking appliance muffle is explosion-proof. The cooking appliance muffle has, on a side of one of the at least one cooking chamber wall facing the cooking chamber, an anti-explosion device that prevents a formation of an explosive gas mixture in any operating state of the cooking appliance muffle.

A rechargeable intelligent arc igniter includes an ignition head and a handle. A front end of the handle is provided with a deformable ignition rod and an illuminating lamp. A front end of the deformable ignition rod is fixed with an ignition head. A printed circuit board is inlaid with an ignition switch and an illuminating lamp switch. A tail end of the handle is set as a flat semicircle, and is smoothly connected with the handle. A hook hole is arranged at a position concentric to the semicircle. A shell of the handle is provided with a circular ignition button and an illuminating lamp button corresponding to the ignition switch and the illuminating lamp switch. The illuminating lamp button is provided with a power indicator lamp. A side edge of the shell is provided with a USB charging interface, and a right side thereof is provided with a power switch.

A Smart Candle Platform may be configured to produce candle light using a natural wax candle as its fuel source or any other fuel source capable of producing light, including liquid fuels if so configured. The outer shell, inner cover, top cover and base provides a beautiful exterior shell which does not melt but emulates the look of a traditional pillar candle. The outer shell may be changeable/replaceable allowing for style and or seasonal changes. A Smart Candle Platform having multiple interactive systems and sensors for production of natural light via a safe, controllable device which may communicate with other similar configured devices or smart devices having application software embedded therein i.e. a smart phone having an app. is disclosed. The Smart Candle Platform may be configured to allow for auto-extinguishment. The Smart Candle Platform may be configured to allow for the addition of smells or scents.

A tool includes a barrel, a guiding wire, and an electrically conductive member. The barrel is made of electrically conductive material. The guiding wire is disposed in the barrel. The barrel and the guiding wire are directly or indirectly connected to two opposite electrodes of a power source. The electrically conductive member is connected to an outer periphery of the guiding wire and is electrically connected to the guiding wire. The electrically conductive member is disposed between the barrel and the guiding wire and is spaced from the barrel. When the power source is activated, an electric arc is generated between the electrically conductive member and the barrel.

Disclosed is a combustion chamber (10) of the carbon dioxide supplier including: a combustion chamber (10) combusting a mixture of air and fuel; an air supply unit supplying an into the combustion chamber (10); and a fuel supply unit supply in a fuel to the combustion chamber (10). Representative Figure is FIG. 6.

An example Smart Candle Platform is configured to includes a candle fixture that comprises an outer shell having an opening, a mid-frame, and a base, and a fuel bottle configured to hold a fuel material and is removably coupled to the candle fixture. The fuel bottle is positioned at least partially within a hollow interior of the mid-frame of the candle fixture and accommodated by the base. The fuel bottle further comprises a wick that extends through an opening of the outer shell, and the candle fixture includes an ignitor configured to ignite the fuel material via the wick to produce a living flame, a proximity sensor to sense a distance between an object and the living flame, a self-extinguisher, and a control system configured to, upon determining the distance between the object and the living flame is unsafe, control the self-extinguisher to extinguish the living flame.
