  • Patent number: 6296475
    Abstract: A gas burner having synchronous ignition and gas supply functions includes a gas storing tank, a gas supply device, a housing, an ignition device, a retaining device, and a burning device. When a press button is pushed, the piezoelectric device is compressed so that a transverse rod is pushed by a push piece to cause a sliding piece and a driven piece to synchronously displace and a shaft spring to retract. The press button enters a wider portion of a lock-shaped hole via a narrower portion. A button spring stretches to cause the press button to be retained in the lock-shaped hole and extend from a piece hole. A gas nozzle is pulled out by a connecting groove for supply of fuel gas via the gas supply device to the burning device. Sparks generated by a lead wire ignites the fuel gas mixture.

  • Patent number: 6293782
    Abstract: A safety device for gas burner includes a securing member, a press member, a slidable member, a retaining member and a button member. By manipulating the press member downwardly to reduce the height thereof, a connecting rod of the slidable member displaces as a result of loss of support from a lap piece, with an abutting rod contacting a stop ice. The connecting rod laps an upper portion of the lap piece so that the press member cannot rebound and is positioned. At this time, when the button member is pressed, an ignition means is simultaneously actuated, and the wall hook causes a gas supply means to supply fuel gas to a burner device. The fuel gas is ignited by means of the ignition means, and a wall rod abuts against a trigger rod. By pressing the retaining member, a fastening rod fastens the gas supply means in position to maintain supply of fuel gas. After use, the button member returns to its original position and is automatically retained by the press member.

  • Patent number: 6294975
    Abstract: Disclosed is a transformer bobbin with hipot-protect structure. The bobbin is integrally formed from plastic material through injection molding and includes a central shaft portion and an outer frame portion at two ends of the central shaft portion. When the bobbin is formed during molding, the outer frame portion is extended from one or two lateral outer ends thereof for a length and therefore forms one or two extended portions on the bobbin. Upright rib or ribs may be additionally provided on top surface of the extended portion. The extended portion provide increased creepage distance between pins connected to outer end surfaces of the bobbin and the core of the transformer to effectively prevent hipot from transiting from pins at one end to pins at the other end by crossing over the core directly.
