The present invention relates to a portable gas burner that makes it easy to bark or cut off poles in places where kitchen facilities are not available, such as hiking, fishing, camping, and outings. Combination and separation of the butane gas cylinder and the combustor body is easy and safe, and the legs attached to the combustor body can be folded to select the installation height of the gas burner, and several combustion holes are drilled around the combustor body. The present invention relates to a portable gas burner that has a structure suitable for efficient cooling as well as easy cooling of the main body.

Portable gas, which is conventionally portable in size, is combined with a combustor body having a simple structure in a tank and separates the fuel tank and the combustor body when transporting and storing without using it, thereby simplifying handling, transport and use. Burner has been woven and sold in various structures. For example, a flammable liquefied butane gas cylinder to which the present invention is applied is regarded as a pedestal, and a nozzle and an adjustment knob are configured at a discharge port of the gas cylinder, and the outlet port is configured to be screwed or separated, and a burner is coupled to the tip of the nozzle. There was a portable gas burner configured to be separated, and another structure included a storage chamber capable of charging and removing a small diameter flammable liquefied butane gas cylinder on one side and a nozzle, burner, trivet etc. on the other side. There was a structure of a portable gas burner in which a combustor body was integrally formed.

However, in the conventional portable gas combustion device configuration, the assembly is generally easy, but there is a problem that the installation on the floor for use is very unstable, and because the structure is so simple, the nozzle is heated during combustion and the nozzle is heated. When the nozzle is made of brass, the thermal conductivity is good, so the heat of the nozzle is transferred to the gas inlet in a short time, and the heat is continuously transferred to the gas cylinder. In addition, the portable gas burner equipped with a separate gas storage compartment is stable in the installation state on the floor to combine the gas cylinder with the combustor body and combusts, but it is difficult to carry due to the large size of the body and the structure is detachable. In some cases, there is a problem in safety to use because it is incompletely coupled to. In addition, the gas combustor has a trivet for assisting the combustion action, and since the assembly thereof is performed in a normal mounting state, there are various problems such as movement by an external force applied in a defenseless state during combustion.

Therefore, in order to solve these problems, the present invention is designed to simplify the structure of the gas cylinder and the structure of the combustor, to have a high safety structure, and to make the size of the combustor body variable while using the compact size of the combustor body. This will be described in detail with the accompanying drawings. A feature of the present invention lies in the combustor body, the combustor body being divided largely as shown in FIG. 1, the bottom plate 2 having a foldable leg 6, and a nozzle 7 having a shorter length. Gas control mechanism (8) and control knob (9) is installed, the body (1) having the air vent for combustion and cooling, and the trivet (5) is inserted and fixed to the maximum area A top plate 3 to achieve the installation effect, and a grill 4 having several jaws 33, 34, 35 and broth holder 28 which securely support the bottom of the heating vessel according to the diameter; And is coupled to the nozzle (7) through the grill is made of a burner stand 40 to help the combustion efficiency by diffusing and discharging the gas.

Referring to the detailed structure of each component for the portable gas burner of the present invention configured as described above, the body (1) is provided with a nozzle (7) and a gas regulating mechanism (8) and knob (9) of a minimum length On the left, right and rear walls except for the front of the hole through the hole (11) and through the hole (12) to free the flow of air, the front of the hole (13) and the semi-circular hole (14) centered on the through hole The shaft 8a of the gas regulating mechanism 8 connected to the nozzle 7 is inserted into the through hole 13 from the inside thereof, and the tip thereof is protruded to the outer surface of the body. The gas adjustment mechanism 8 is adjusted according to the adjustment state of the knob so that the gas amount is adjusted by an operation in which the gas discharge hole is developed or closed in the nozzle 7. 8a) and the engaging portion of the adjusting knob (9) in the groove, such as hexagon, square, triangular and vandal key shape Assembly by a coupling to be be fulfilled accurately control operation of the control knob (9).

In addition, in the nozzle 7 protruding above the adjusting mechanism 9, an insulating layer 39 is formed of an insulating material having good thermal insulation property, and the heat of the burner stand 40 coupled to the nozzle 7 is cut by the gas adjusting mechanism. Block it from becoming

The pressure jaw 9a protrudes from the inner surface of the control knob 9 so that the pressure jaw 9a is fitted into the bar hole 14 of the body 1 to limit the rotation range of the control knob 9.

In addition, the pressing jaw (9a) acts to press the piezoelectric force (15) fixed at the lower position of the body semi-circle hole 14 to achieve the role of an ignition switch.

The unfired tip 15a (shown in FIG. 5) of the piezoelectric member 15 fixed to the body 1 is fixed to the grill 4 described later. The bottom plate 2 is assembled to the bottom of the body (1). The bottom plate 2 is assembled to the bottom plate 2 at the bottom of the body (1). The bottom plate 2 is formed to be extrapolated to the bottom of the body (1) to process the central portion to protrude in the upward direction in order to increase the bending strength of itself to drill the coupling hole 16 in the center.

In addition, the bottom plate 2 is formed by forging a rectangular protruding boss 17 extending from the protruding start portion to the four corners in the forging process, and punching several holes 17 'around the bottom plate 2.

In addition, the left and right bottom surfaces of the bottom plate 2 are formed by cutting and bending the support pieces 18 extending vertically to the bottom of the bottom plate at regular intervals or by separately manufacturing and fixing them by spot welding.

Thereafter, the support piece 18 of the bottom plate 2 is provided with a leg 6 corresponding to the height of the flammable liquefied butane gas cylinder 10 (see FIG. 4). It is desirable to cover the rubber ring 19 as shown in FIG. 3 in order to increase the shock absorption of the leg, and when the leg 6 is extended, the oblique angle is slightly larger than 90 with respect to the base plate 2 when the leg 6 is extended. Since the stopper 20 formed on the upper surface touches the bottom of the bottom plate 1 and should be installed so that it cannot be unfolded further, the bridge itself needs to have sufficient strength to endure the load applied from the upper part of the combustion apparatus. The support piece 18 is formed by using a wire or the like having a thickness sufficient to withstand the load, and furthermore, to withstand the load.

At this time, it is preferable to equip the upper end of the leg with a stopper 20 which can be stopped at an angle (about 100) slightly larger than 90 with respect to the bottom plate 1.

In addition, the coupling hole 16 formed in the protrusion of the bottom plate (1) is coupled to the nozzle (7) of the body (1) from the inside to the outside to the rubber packing (21) and the nozzle portion protruding outside the bottom plate (2) The thread 23 formed on the outer circumference of the discharge port 10a of the gas cylinder 10 by filling the ring nut 22 is screwed to the screw hole 7a of the nozzle 7 exposed to the bottom of the bottom plate 2. To allow separation.

In addition, the upper plate 3 is formed at a size at which the upper plate 3 is tightly assembled at the upper end of the body 1 while bending the large through hole 25 at the center thereof to bend the inner circumference of the large through hole 25 in the upward direction. Press working.

In this press operation or in another press operation, the small hole 6 for fixing the pedestal is drilled from the center to the edge.

Thereafter, the grille 4 is formed to be inserted into the large through hole 25 of the upper end 3, and the grill 4 has a diameter of a size that is extrapolated to the feather 25a of the upper plate 3 of the large through hole 25. (27) (see Fig. 3), while forming the grate receiving portion 28 to be inserted into the body (1) and the center portion of the grill (4) while the hole 29 is circumferentially raised upwards The stator of the piezoelectric body 15, which has a shape that comes in shape and forms a protrusion as shown in FIG. 3, and then drills a small through hole 30 in the bottom and the upper surface, respectively, and is drilled in the side of the soup receiving part 28. 32) to fix the spot welded clamp around the hole with a screw (38).

In addition, the upper surface of the grill 4 faces the four corners of the upper plate 3 and has several supporting jaws 33, 34, 35 to fix the pedestal 5, which is usually called a trivet, by welding to form an integrated structure. Equipped.

And the lower end of the end of the pedestal (5) protruding the insertion jaw 36 to prevent the insertion jaw 36 is inserted into the small hole 26 drilled in the upper plate (3) to prevent flow.

The supporting jaws 33, 34, 35 formed on the pedestal 5 have several shapes because the bottom diameters of the heating vessels are different. Alternatively, the jaw height of the pedestal end is exceptionally high. The bottom of the heating vessel can be fitted in 35) to fundamentally eliminate the problem of the container slipping or slipping out of the range due to a slight external shock.

The present invention having such a configuration rivets or pins the legs 6 to the bottom plate 2 or the support piece 18, and then the screw holes 7a of the nozzles 7 to the center coupling holes 16. The ring nut 22 together with the rubber packing 21 at the bottom of the bottom plate 3 and screw it into the screw hole 7a to fix it, and then assemble the body 1 to the bottom plate 2 while Screw the adjusting knob 9 to the end of the shaft 8a where the shaft 8a of the gas regulating mechanism 8 of 7 is fitted into the bottom through hole 13 of the body 1 and is exposed to the wall of the body 1. (38) and then the piezoelectric 15 is fixed to the inner surface of the lower position of the semi-circle 14 of the body (1). Then, the tip 15a of the piezo 15 is fixed to the broth portion 28 and clamped by a screw 38 to fasten the grille 4 to the large through hole 25 of the upper plate 3. When the insertion jaw 36 of the pedestal 5 is inserted into the small hole 26 of the upper plate 3 while being inserted, the tip of the nozzle 7 is exposed by the hole 29 drilled in the center of the natural grill 4. .

When the tip of the nozzle and the normal flame spreading burner stand 40 are assembled in the exposed state, the grille 4 is stable to the body 1 while the nozzle 7 and the burner stand 40 are coupled. Is fixed. Then, when the gas burner is to be used, the nozzle (7) is inserted into the screw hole (7a) exposed to the bottom surface of the bottom plate 2 by inserting the discharge port (10a) of the combustible liquefied butane gas cylinder (10) Pins in the) presses the discharge side in the gas cylinder 10, the gas comes out through the nozzle.

At this time, the adjusting shaft 8a connected to the adjusting knob 9 is in the closed state of the nozzle 7, so that gas cannot be supplied to the burner stand 40.

Therefore, only when the user wants to ignite the gas burner, when the adjusting knob 9 installed on the front of the body 1 is turned counterclockwise, the shaft 8a which closes the inside of the nozzle 7 rotates and the nozzle 7 Since the inside is gradually opened, the gas is diffused and discharged through the burner stand 40 connected to the gas.

If the adjustment knob 9 is continuously turned, the opening state of the nozzle 7 is maximized while the discharge amount of gas is maximized, and the pressure jaw 9a of the adjustment knob 9 presses the piezoelectric force 15. The piezoelectric force is generated by the piezoelectric element 15, and at the same time the pressing jaw (9a) is caught in the semi-circular hole 14 can no longer rotate.

When the piezoelectric member 15 is pressed by the knob rotation, discharge occurs at the tip 15a located in the soup receiving unit 28 to ignite the gas that is sparked and diffused and discharged.

However, at this time, since the maximum gas discharge state, the natural flame is also the maximum state, and according to the object, the knob 9 is rotated again to adjust the open / close state of the nozzle to the shaft 8a to adjust the flame size.

At this time, the support jaw 33, 34, 35 of the pedestal 5 supports the bottom of the container while some of the jaws 35 protect the outer circumference of the bottom of the container, so that the container is supported even if a slight impact is applied to the container. (5) There is no slipping on it. Especially, the legs of the bottom plate (2) form an obtuse angle larger than 90 and the gas burner is able to withstand a slight impact since the obtuse state supports the gas burner. There is no at all.

In the combustion process, the burner stand 40 is gradually heated, and the heat is transferred to the gas cylinder 10 along the nozzle 7, but in the present invention, the insulating layer 39 is formed between the nozzle 7 and the regulating mechanism 8. ), The thermal conductivity is remarkably lowered so that a very stable effect can be obtained. If you want to stop the combustion of the gas burner afterwards, turn the knob 9 in the opposite direction to ignite the knob. The shaft 8a connected to the gas block blocks the outflow of the gas to extinguish the combustion state. Then, the gas cylinder 10 in which the gas is consumed is turned out in the opposite direction of tightening, and a new cylinder is combined or cooled in the air.

In this cooling process, the air is circulated in the periphery and bottom of the body 1 and the combustor body including the burner heated to the hot hole 11 and the through hole 12 is cooled rapidly. As described above, the present invention is simple in structure, and the gas supply blocking action is assured, and the support base structure on the pedestal also has no fear of the container falling off to a slight impact, and when the size of the gas range is used, the legs are erected and stable. As it is installed, the angle of the foot is maintained enough to withstand the slightest impact from the outside, so it is not only very stable but also easy to use and separated from the gas cylinder, so it is very convenient to use and easy to carry and handle. In addition, there is a solid feature to improve the quality and performance of the product has the advantage of providing a high-safety products of gas combustion equipment.
