Description
FIELD OF THE INVENTION
[0001] The present invention relates to a lighter, particularly to
a double-flame lighter.
BACKGROUND OF THE INVENTION
[0002] 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.
SUMMARY OF THE INVENTION
[0003] 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.
[0004] 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.
[0005] Advantages of the invention are as follows: as 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 simple structure with convenient
operation and safety.

DETAILED DESCRIPTION OF THE INVENTION
[0010] The present invention will be further described with
reference to the drawings and the embodiments.
[0011] 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 are communicated 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 is actuated with 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 boards 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.
[0012] 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.
[0013] 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 boards 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 boards 13, 14, and the press
board 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.
[0014] 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.
[0015] 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.
