The present invention relates to a cigarette lighter having a fuel reservoir configured to contain a combustible fuel. The cigarette lighter includes a pre-mixing burner flame generating unit configured to mix the combustible fuel with air and contain a flame. The cigarette lighter includes a valve in fluidic communication with the fuel reservoir and the pre-mixing burner flame generating unit and configured to facilitate the combustible fuel to enter the pre-mixing burner flame generating unit when the valve is actuated. The cigarette lighter includes a bracket configured to actuate the valve when a force is applied by a user and includes a friction wheel assembly in mechanical communication with the bracket and configured to rotate about an axis. The cigarette lighter includes a flint in mechanical communication with the friction wheel assembly and configured to emit spark when the friction wheel assembly is rotated about the axis by a user.

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 flame producing assembly is provided. The flame producing assembly includes a body housing a piezoelectric ignition device, and 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 flame producing assembly includes a pocket lighter, an extended wand, a rigid support, and a helical spring. The pocket lighter extends along a longitudinal axis and defines a length. The pocket lighter includes a piezoelectric ignition device operable to produce an electric charge. The extended wand is electrically coupled to the piezoelectric ignition device. The rigid support is disposed inside the extended wand and includes a longitudinal inner opening. The helical spring extends along the longitudinal inner opening and protrudes beyond a free end of the rigid support. The free end is opposite a connecting end that is proximate to the pocket lighter.

A flame producing assembly including a pocket lighter and a sub-unit assembly. The sub-unit assembly includes an extended wand, a rigid support and a helical spring. The pocket lighter is connected to the sub-unit assembly. The pocket lighter includes a piezoelectric ignition device. The rigid support is located inside the extended wand and includes a longitudinal inner opening. The extended wand is electrically coupled to the piezoelectric ignition device, wherein the pocket lighter is connected directly to the sub-unit assembly and wherein the helical spring extends along the longitudinal inner opening.

According to some aspects a safety lock may be provided for locking a lighter switch, rendering it necessary to push a safety push button forward to separate the locking projection of the locking lever from the engaging groove of the lighter switch, and then press the lighter switch to touch the circuit board switch to operate the lighter (e.g., ignite the lighter's flame). Normally, the arc emission end is disposed in the protective cover which may protect the arc emission end and avoid dangerous situations. When the safety push button is pushed forward, the arc emission end may be pushed out from the protective cover, ready to ignite. Aspects of this disclosure may provide advantages such as simple overall structure, high levels of safety, and safe and reliable use of lighters.

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 torch device having a pivoting torch arm, including a fuel delivery system having a fuel tank and microjet burners positioned in the end of the torch arm, and an ignition system including an ignition button and a piezoelectric igniter for igniting fuel, and an interlock mechanism including a mounting tab pivotally attaching the torch arm to the body of the torch, with a guide pocket defined by a laterally-extending wall of the mounting tab, and a rocker arm having a distal arm cooperating with and confined within the guide pocket, and a proximal arm cooperating with the ignition button, and configured to prevent a user from pressing the ignition button based on the angular position of the torch arm relative to the torch body.
