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.

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. The candle fixture further includes an inner cover having one or more reinforcement ribs configured to provide structural support for the one or more ignitors.

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 lighter includes a fuel casing, a gas-releasing nozzle, a supporting frame provided on the fuel casing, a fuel mounting frame, a spark wheel, a flint member and an actuator. The flint mounting frame has an upper operative frame detachably mounted on the supporting frame, and a lower mounting frame extended into the fuel casing. The spark wheel is rotatably supported on the upper operative frame of the flint mounting frame. The flint member is detachably mounted in the lower mounting frame of the flint mounting frame and extended toward the upper operative frame to communicate with the spark wheel. When the flint mounting frame is detached from the supporting frame and the fuel casing, the flint member is capable of being detached from the lower mounting frame for replacement of a new flint member.

A lighter comprises a housing having a nozzle, wherein the housing is adapted to receive a gas and/or fuel reservoir device. The lighter comprises a connecting device, wherein the connecting device is configured to couple the gas and/or fuel reservoir device to the nozzle. The connecting device is adjustable along a longitudinal axis of the lighter.

A method for igniting a refillable gas lighter comprises a rear case, a front case and a barrel. The lighter is provided with a physical phenomenon of piezo-electric effect to generate the electric spark. Inside the rear case, the pusher is pressed down to the gas tank with the pusher having a plurality of conducting strips that acts as an electrical conductor connected to the gas tank. A copper wire carrying negative charge is connected with a bridge plate that passes through the conductive hose to achieve fuel distribution and electric conduction. The conductive hose transfers the igniting gas from the gas tank to the spark plug, where the ignition initiates the flame. The housing assembly includes a rear case with a rear case neck, a front case with a front case neck, and a barrel. The housing assembly is further locked together by means of a barrel sleeve where the barrel has a flame opening to ignite.
