The present invention relates to a lighter, particularly to a double-flame lighter.

At present, a double-flame lighter mainly includes two kinds of structures. One has a double-flame nozzle assembly. Conversion between naked flame and windproof flame is achieved in one flame nozzle assembly (windproof flame assembly) by a flame converting mechanism and a gas supply controlling mechanism, e.g., the Chinese patent with patent number of 92100999.2, grant announcement number of CN1055336C, entitled with "Double-Flame Lighter with High Ignition Efficiency", and the Chinese patent application with application number of 92109388.8, publication number of CN1082692A, entitled with "Double-Flame Lighter", are of the structure mentioned above. The other has two separate flame assemblies, both of which may be naked flame assemblies or windproof flame assemblies, or one of which is naked flame assembly and the other of which is windproof flame assembly, or other forms of flame assemblies, e.g., jet flame assemblies, e.g., the Chinese patent of utility model with patent number of 01210364.0, grant announcement number of CN2465069Y, entitled with "Multi-flame Lighter". Said multi-flame lighter comprises more than two flame assemblies, a housing, an igniter, a gas outlet valve, a gas tank, an ignition switch, and a spring board which is interlocked with the ignition switch and activates the gas outlet valve to exhaust. The key point of the multi-flame lighter lies in that conversion of the flames is achieved by a rotatable conversion wheel. Disadvantage of the lighter is that the conversion wheel has to be turned first to obtain a flame of the other form, which is inconvenient. Moreover, the conversion wheel tends to be damaged and cause leakage under frequent turn.

The problem to be solved by the present invention is to overcome shortcomings of the prior art, and provide a double-flame lighter of simple structure with convenient operation and safety.

The technical solution adopted in the present invention to solve the technical problem mentioned above is as follows: a double flame lighter comprises two flame assemblies, i.e., a first flame assembly and a second flame assembly, disposed on a housing, igniters, a tank provided with a gas outlet valve, and an ignition button. There are two igniters, and a gas nozzle of the gas outlet valve is a double-headed gas nozzle whose two gas outlet pipes are communicated with the first flame assembly and the second flame assembly respectively. A two-way spring board is disposed on the gas outlet valve, and a two-way movable ignition button that is actuated with the igniters and the two-way spring board is disposed on the housing. There is a switch mechanism disposed between the ignition button and the gas outlet pipe for controlling closing or opening of the gas outlet pipe.

Advantages of the invention are as follows: only the two-way movable ignition button and the two-way spring board are used in the present invention and the double-flame ignition is achieved by the switch mechanism of the gas outlet pipe. So the invention has advantages of a simple structure with convenient operation and safety.

The present invention will be further described with reference to the drawings and the embodiments.

As shown in Fig. 1, which is a structural schematic view of the first embodiment of the invention, a double-flame lighter comprises two flame assemblies, i.e., a first flame assembly 2 and a second flame assembly 3, disposed on a housing 1, igniters 4, a gas tank 6 provided with a gas outlet valve 5, and an ignition button 7. There are two igniters, and a gas nozzle of the gas outlet valve is a double-headed gas nozzle whose two gas outlet pipes 8, 9 communicate with the first flame assembly 2 and the second flame assembly 3 respectively. A two-way spring board 10 is disposed on the gas outlet valve 5, and a two-way movable ignition button 7 that actuates the igniters 4 and the two-way spring board 10, with which it is matched, is disposed on the housing. Two fulcrums 15, 16 of the spring board are disposed on the gas tank 6, and two press pieces 17, 18 are disposed on the ignition button 7. A switch mechanism 11 for controlling closing or opening of the gas outlet pipes 8, 9 is also provided on the ignition button 7 and the housing 1. Said igniters 4 are movably disposed in an igniter groove 12, which is fixedly connected to the housing 1. The gas outlet pipes 8, 9 pass between the igniters 4 and the bottom surface of the igniter groove 12. When the ignition button 7 is pressed, the igniters 4 will move in company with the ignition button 7, oppress the gas pipes, and then close the gas path. When the ignition button 7 is released, the igniters 4 will restitute under the resilience of the gas pipes 8 or 9, and then the gas path is opened. Thereby, the switch mechanism 11 for closing or opening the gas path is formed. Said two igniters 4 are disposed in rectilinear direction in the housing 1.

The second embodiment of the invention, whose structural schematic view is shown in Fig. 2, differs from the first embodiment only in that said igniters 4 are disposed in parallel in the housing 1.

The difference between the third embodiment of the invention, whose structural schematic view is shown in Fig. 3, and the first embodiment lies in the switch mechanism 11. In this embodiment, said igniters 4 are fixedly disposed in the housing 1, and the press pieces 13, 14 of the gas pipes are disposed on the ignition button 7 and the housing 1 respectively. The gas outlet pipes 8, 9 pass between the two press pieces 13, 14, and the press piece 13 on the ignition button 7 moves in company with it and oppresses the gas outlet pipes. Thus, the switch mechanism 11 for closing or opening the gas path is formed.

The fourth embodiment of the invention, whose structural schematic view is shown in Fig. 4, differs from the third embodiment only in that said igniters 4 are disposed in parallel in the housing 1.

It is to be noted that the two-way action of the ignition button 7 may be a linear reciprocating motion or a swaying motion, both of which will fall into the scope of the invention.
