Hereinafter, an operation and a working principle of the gas lantern for a portable gas stove according to an embodiment of the present invention will be described.

When the gas fuel in the gas container C is injected into the venturi 30 through the valve casing 10 and the nozzle 20, the air pressure around the venturi 30 falls. At this time, Outside air is naturally introduced into the venturi 13 through the air hole 26 and mixed into the chamber 61 while passing through the venturi 13 together with the gaseous fuel.

The mixed gas of air and gas in the mixed chamber 61 is uniformly dispersed and diffused by the distribution plate 66. The mixed gas is dispersed and diffused even more uniformly while passing through the flame formation plate 70 .

Thereafter, the mixed gas is ignited by an igniting mechanism such as a lighter, and is burned in all directions along the entire surface of the flame forming plate 70, so that the flame can steadily and steadily bake to heat the object to be heated.

In this process, even if the flame suddenly reverses the flow of the mixed gas, the distribution plate 66 safely blocks the flame, thereby preventing an accident or a failure due to backflushing.

That is, since air and gas are mixed, dispersed and diffused, and even flame blooms, combustion efficiency and heat generation performance can be greatly improved.

The amount of the external air introduced into the venturi 30 through the air hole 26 can be controlled by rotating the air control ring 40 while adjusting and maintaining the gas ejection amount and the pressure of the gas container C to a predetermined range The first mounting bracket 80 for a lantern and the second mounting bracket 90 for a burner can be selectively attached to and detached from the head 60. [

That is, when the air control ring 40 is screwed to the lower portion of the venturi 30 and the air hole 26 is opened by the rotation operation, a flame for the burner is generated, , A lantern flame is formed which looks like a candle.

Accordingly, the gas stove or the gas lantern can be easily changed and used according to the user's need or selection. Therefore, the gas stove and the gas lantern can be separately provided to solve the inconvenience of the user having to carry or store separately.

In addition, since the valve casing 10 and the venturi 30 are indirectly connected to each other by a predetermined space without being directly connected to the sleeve 25, heat transmitted to the gas container C can be minimized, The heat generated in the combustion process can be naturally cooled by the air in the state where the air hole 26 of the sleeve 25 is opened, so that the effect of minimizing the heat conducted to the gas container C can be obtained.

8, another embodiment of the present invention is that the heat of the flame forming plate 70 is applied to the venturi 30 and the valve casing 10 on the contact surface between the sleeve 25 and the venturi 30. [ (Bad conductors) having a small thermal conductivity may be interposed between the heat exchanger 27 and the gas container C to block and minimize the transfer of the gas to the gas container C.

That is, the sleeve 25 and the heat shield ring 27 are configured to minimize the contact area so that the installation space between the valve casing 10 and the venturi 30 is maintained at a constant space. Therefore, during the combustion process, It is possible to more effectively block and minimize the heat transfer to the gas container C.

Therefore, it is possible to enhance the safety of preventing the phenomenon that the gas container C is physically deteriorated because it can not withstand the internal pressure due to the decrease in strength due to overheating.

Herein, the components having the same or similar operational effects as those of the above-described embodiment among the components related to the portable gas stove and the gas lantern according to another embodiment of the present invention are denoted by the same reference numerals, Is omitted.

On the other hand, in order to control the flame emitted from the flame forming plate 70 to be smoothly and stably raised when using as a gas lantern, a vent hole 82 for inducing air flow must be provided. However, When the wind comes in through the vent hole (82) from outside when it is blooming, it can easily shake, and the light can bloom freely or can be scattered.

9 and 10, when the flame emitted from the flame forming plate 70 enters the vent hole 82 of the first mounting bracket 80 as shown in FIG. 9 and FIG. 10, (Not shown).

The first mounting bracket 80 is provided at its upper outer periphery with a support protrusion 88 protruding from the upper end of the first mounting bracket 80. The wind shield 96 is formed in a tubular shape so as to surround the first mounting bracket 80 with a clearance therebetween, And a hooking jaw 97 is formed on the upper circumferential surface of the hollow so as to maintain a state of being laid on the receiving jaw 88 of the first mounting bracket 80. [

Thus, when the gas lantern is used as a gas lantern, the external wind can flow into the vent hole 82 naturally in a state where the wind speed is weakened while entering through the lower gap between the first mounting bracket 80 and the windshield 96.

Accordingly, the flame emitted through the flame-forming plate 70 prevents the wind directly entering the vent hole 82 from directly fitting, thereby effectively preventing the light from being shaken by the external direct wind.

Herein, the components having the same or similar operational effects as those of the above-described embodiment among the components related to the portable gas stove and the gas lantern according to still another embodiment of the present invention are denoted by the same reference numerals, The description is omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments or constructions. Various changes and substitutions may be made without departing from the spirit and scope of the invention. It will be obvious to those skilled in the art that the present invention can be widely applied to other embodiments.

Therefore, it is to be understood that modifications and variations of the features of the present invention are intended to be included within the spirit and scope of the present invention.
