Patent ID: 7011515

Claim:
A gas lighter with a device for preventing flame from being extinguished by wind, the gas lighter comprising: a housing including a gas fuel reservoir disposed in a rear part thereof, a valve disposed on one side of the gas fuel reservoir, and an arc generator disposed on another side of the gas fuel reservoir, the arc generator including a first conductor and a second conductor extended therefrom; a trigger partially projected from an opening of the housing, the trigger being configured and arranged to activate both the valve for discharging gas fuel from the gas fuel reservoir and the arc generator for generating an arc; a barrel extending forwardly from the housing and including a nozzle disposed at one end of the barrel, a ceramic sleeve member disposed in the barrel adjacent the nozzle, an auxiliary ceramic sleeve member disposed at a first end of the sleeve member distal from the housing, the auxiliary ceramic sleeve member having a first end distal from the sleeve member disposed at a forward end of the nozzle, a guide sleeve disposed at a second end of the sleeve member, a burning member disposed at a second end of the auxiliary ceramic sleeve, and a gas pipe disposed on the guide sleeve wherein the first conductor of the arc generator is disposed on the guide sleeve, a first end of the gas pipe is coupled to the valve of the gas fuel reservoir and a second end of the gas pipe is coupled to the burning member such that gas fuel in the gas fuel reservoir is adapted to flow to the burning member via the gas pipe for ignition, the first conductor being electrically connected to the burning member, and the second conductor of the arc generator being electrically connected to the barrel; and a safety assembly including a metal ring disposed at one end of the auxiliary ceramic sleeve member distal from the sleeve member, a radial metal filament disposed in the metal ring, and a metal block disposed in a center of the metal filament; wherein the safety assembly has a metal sleeve disposed on the metal ring, the metal sleeve having a lower part with a forward end of the auxiliary ceramic sleeve member received therein, and a plurality of equally spaced apart longitudinal channels disposed in and around the concentric, cylindrical nozzle so as to provide a flexibility at a forward end of the nozzle, wherein an inner diameter of the forward end of the nozzle is slightly smaller than an outer diameter of a bottom flange of the metal sleeve such that the forward end of the nozzle will be enlarged by the metal sleeve when the metal sleeve is installed therein for causing the forward end of the nozzle to clamp the metal sleeve for fastening both the metal ring and the forward end of the auxiliary ceramic sleeve member by the flexibility; wherein the arc generator is adapted to ignite flame at the forward end of the nozzle and heat the metal block to be hot enough to ignite gas fuel, and in a case of flame extinguished suddenly by wind, the metal block is adapted to ignite a flame again within one second.
