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 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 torch includes a body, a fuel tank and a microjet burner. The torch also includes an ignition button that is movable relative to the body between an upper position and a depressed position, and a cap assembly, which includes a lower cap and a safety cap rotatably coupled with the lower cap. The safety cap includes an ignition button guard, defines a flame portal, and is rotatable between a closed position and an armed position. When the safety cap is in the closed position, the ignition button guard is aligned with the ignition button and inhibits access to the ignition button, and the safety cap covers the microjet burner. When the safety cap is in the armed position, the flame portal is aligned with the microjet burner, and the ignition button guard is misaligned with the ignition button, and access to the ignition button is unobstructed.

A safety device for a gas burner includes an ignition-gas unit and a lever is pivotably connected to the installation port. The lever extends beyond a cover on the ignition-gas unit and includes a free end to which a restriction member and a spring are connected. The spring drives the restriction member toward the cover to restrict the lever from being pushed to ignite the gas burner. When the restriction member is moved, the user can push the free end downward to activate the ignition-gas unit to ignite the gas burner.

An igniter with a safety protection device (5) and an ignition control method therefor. The igniter comprises an ignition switch (3) and an energy supply module (4). The safety protection device (5) comprises a safety switch (51), a trigger module (52) and a wireless transceiver module (53), wherein the wireless transceiver module (53) can transmit a wireless request signal, receive a wireless response signal from an external device (2) and transmit the received wireless response signal to the trigger module (52), and the trigger module (52) triggers the safety switch (51) according to the wireless response signal to enable the safety switch (51) to act, so that ignition can be realized, and the ignition cannot be realized even the ignition switch (3) is actuated when the wireless transceiver module (53) does not receive the wireless response signal. The igniter can effectively prevent children or disabled persons from accidentally using the igniter.

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.

Lighters are disclosed herein. An example lighter includes a base and a flame ignition assembly at least partially disposed in the base. The flame ignition assembly includes a nozzle. The example lighter also includes a button having an opening. The nozzle is disposed in the opening of the button. The is button to, when depressed, cause the flame ignition assembly to produce a flame at the nozzle.

A torch includes a body, a fuel tank and a microjet burner. The torch also includes an ignition button that is movable relative to the body between an upper position and a depressed position, and a cap assembly, which includes a lower cap and a safety cap rotatably coupled with the lower cap. The safety cap includes an ignition button guard, defines a flame portal, and is rotatable between a closed position and an armed position. When the safety cap is in the closed position, the ignition button guard is aligned with the ignition button and inhibits access to the ignition button, and the safety cap covers the microjet burner. When the safety cap is in the armed position, the flame portal is aligned with the microjet burner, and the ignition button guard is misaligned with the ignition button, and access to the ignition button is unobstructed.
