A safety switch for use in a gas combustor is disposed on a gas combustor having a rear opening, and a press button is arranged adjacent to the rear opening; the safety switch includes a locking member and a swing arm, the locking member has a main body sleeved with a longitudinal spring, and a locking hook protruded from a location towards a latching hook arranged above the swing arm, wherein a transversal spring is disposed between an extending sheet below the swing arm and the inner wall of the gas combustor; when the locking member is not pressed, the locking hook is abutted against the latching hook, a locking bolt protruded from a bottom end of the press button is abutted against the locking hook, so that the press button is unable to be pressed, thereby forming a locked status.

A burner gun includes a case, an ignition device, a switch and a operational part. By the switch and an operation rail in the case, the ignition device can only be activated by correctly operating the switch and pulling the operational part. The ignition device cannot activated by pulling the operational part if the switch is not correctly operated, so that the ignition device is prevented from being activated unintentionally to reduce possibility of causing fire disasters.

The present invention relates to a gas burner. The gas burner is also called a gas range, a gas grill, or the like and used to cook food indoors or outdoors. To this end, a supply part and an extension part are configured to be foldable through a body hinge part such that the supply part, the extension part, and a cooking part may be folded into one piece, and support parts are also configured to be folded through hinges (pivots) such that the support parts may be adjacent to the supply part. The gas burner including the supply part and the cooking part further includes the extension part having a length, the other end of the supply part is connected to one end of the extension part by means of the bendable body hinge part, and the cooking part is configured at the other end of the extension part.

A handheld welding torch apparatus for welding in confined areas includes a gas tank having a handle portion and an extension portion. Each of the handle portion and the extension portion is cylindrical. A valve assembly is coupled to the gas tank and comprises a tank receiver, a tube stem, a valve housing, and a control valve. The tube stem is coupled to the tank receiver. The tube stem is in fluid communication with the gas tank when the tank receiver is engaged with the extension portion. The valve housing is coupled to, and in fluid communication with, the tube stem. The control valve is coupled within, and in fluid communication with, the valve housing. A tube neck is coupled to, and in fluid communication with, the control valve. A welding tip is coupled to the tube neck.

A “flame show” is responsive to an audio input signal such as music. A base unit including an analog base unit controller circuit is arranged to receive an audio input signal and generate an analog control signal that is responsive to the audio input signal. The analog control signal is distributed, by wire or wireless, to one or more flame display units such as a “tiki torch.” Each flame display unit has a fuel source, and a proportional valve for controlling an amount of fuel supplied to a burner. Preferably, the control signal controls a gate terminal of a MOSFET semiconductor device, which in turn is coupled to control current in the proportional valve each each unit. By deploying multiple flame display units, all coupled to the same base unit, all of the flame display units contribute synchronously to the overall flame show.

[Problems] A flat burner elongated in the longitudinal direction has, at an upper end thereof, a main burner port (63) and a flame retention port (64) positioned at least on laterally one side of the main burner port (63). The flat burner uses hydrogen-containing fuel as a fuel. Flash back is prevented at the flame retention port in which the gas ejection speed becomes relatively small. [Solving Means] A lean fuel-air mixture which is leaner in fuel concentration than a theoretical fuel-air ratio is ejected from the main burner port (63) and a gas containing only fuel is ejected from the flame retention port (64). In addition, the height, on the side of the main burner port (63), of the upper end of the flame retention port (64), is made lower than the height of the upper end of the main burner port (63).
