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.

A lighter has a safety button and an ignition trigger arranged on the lighter housing such that an activation force required to move the safety button to an activate position and an ignition force required to move the ignition trigger in an ignition direction are directed opposite to one another. The safety button is arranged on the housing for contact by the purlicue of the user's hand and the trigger is arranged on the housing for contact by a finger of the hand. Consequently, operation of the safety button is concealed during use, and the lighter is operable using only one hand.

A flame producing assembly includes a body housing a piezoelectric ignition device, an extended wand extending longitudinally from the body and electrically coupled to the piezoelectric ignition device, and a helical spring extending longitudinally within the extended wand. The piezoelectric ignition device is operable to produce an electric charge. The helical spring includes a first end portion and a second end portion. The second end portion is a diffuser.

A device including a device body for storing fuel; a spark wheel that may be used as a first fidget device is configured to rotate against a flint to produce igniting sparks; a flame setting indicator for indicating low flame (LO), high flame (HI), and flame off (OFF); a tab portion for pointing to at least one of the flame setting settings; a flame-height adjuster for decreasing or increasing a flame ignited by said sparks, or turning off a supply of fuel; a rotating disc implement that may be used as a second fidget device, wherein the rotating disc implement is configured to significantly flush-mount against the device body and to customarily rotate freely against the device body; a circular indentation implement disposed on a proximate center portion of said lighter body section is configured to generally secure said rotating disc implement.

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 (1) has a container (16) of gas, a first gas circuit (26) intended to produce a first type of flame (2) and a second gas circuit (24) intended to produce a second type of flame (3). The lighter (1) further has a driver (6) associated with a mechanism (14, 15) for producing sparks, activation in rotation of said driver (6) generating sparks. The driver (6) is mounted in the lighter (1) to be mobile in translation between a nominal first position in which it holds the first circuit (26) open in order to allow the gas from the container (26) to pass through the first circuit (26) and thus to obtain the first type of flame (2). A second position is provided in which it blocks the first circuit (26) in order to allow the gas from the container (16) to pass through the second circuit (24) and thus to obtain the second type of flame (3).

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.
