US 5,055,034 A · Windproof cigarette lighter with double flames

Abstract

This invention relates to a windproof cigarette lighter with double flames, producing not only windproof type, but also a visible flame. It comprises: a housing, a gas reservoir, a gas charging valve, a gas discharging valve with discharging amount adjustable and valve opening member. A nozzle of the gas discharging valve is connected to the inlet of a burner through a first conduit. A piezoelectric igniting device is activated upon the opening of the gas discharging valve. The burner consists of a jet pump, a combustion chamber and a flame stabilizer which is composed of a central hub and at least a channel between the central hub and the wall of the combustion chamber. An igniting element is arranged on the downstream portion of the combustion chamber. A second conduit is connected to a nozzle which is located on the top center of the central hub and has its opening vertically upward. The central region of cross section of the combustion chamber is empty so that the combustible gas can be ejected upwardly without interruption. The windproof cigarette lighter with double flames of the present invention possesses not only the capability of resisting the wind, but also overcomes the shortcomings of the existing windproof lighter, i.e., when it is used in a bright environment, the user can hardly see the position of the flame. It can be used as either a general lighter with visible flame or a windproof lighter.

A windproof cigarette lighter with double flames comprising:

a housing;
a reservoir to store the gaseous fuel;
a gas charging valve mounted on said reservoir;
a gas discharging valve whose gas discharging amount is adjustable and a valve opening member;
a nozzle of said gas discharging valve being connected to the inlet of a burner through a gaseous fuel conduit;
a piezoelectric igniting device which is activated upon the opening of said gas discharging valve;
said burner including a jet pump, a flame stabilizer and a combustion chamber;
said jet pump having a fuel ejecting orifice at its inlet portion and a plurality of air intake holes on the wall of a downstream passage extending from said fuel ejecting orifice;
said combustion chamber coaxial with said jet pump unit being on the other end of said burner;
said flame stabilizer forming a channel with the wall of the lower part of the combustion chamber;
an igniting element being arranged on the downstream portion of said combustion chamber for reigniting the gaseous air/fuel mixture;
wherein the improvement comprises:
a second gas conduit being connected to a gaseous fuel nozzle which is located on the top center of said flame stabilizer and has an opening directed vertically upward for producing visible flame;
and
said igniting element being arranged in the vicinity of the wall of said combustion chamber, the central region of cross section of said combustion chamber being empty, so that the combustible gas can be ejected upwardly without interruption.
