## Abstract

Disclosed is a portable gas stove including a body including a nozzle configured to spray a gas supplied through an inlet, a Venturi tube configured to change a pressure of the gas sprayed from the nozzle, and a chamber into which the gas discharged from the Venturi tube is introduced, a first distribution plate mounted at one side in the chamber and including a plurality of flow paths, a second distribution plate mounted on the chamber to be spaced a predetermined distance from the first distribution plate, a flame forming plate mounted on the second distribution plate and configured to disperse, diffuse, and discharge a mixture of the air and gas discharged from the slot through a plurality of tiny holes, and a mesh mounted on the flame forming plate and configured to diffuse combustion heat of the mixture discharged through the tiny holes is disclosed.

## Claims

### Claim 1

A portable gas stove comprising:
a body (10) including a nozzle (12) configured to spray a gas supplied through an inlet (11), a Venturi tube (13) configured to change a pressure of the gas sprayed from the nozzle (12), and a chamber (14) into which the gas discharged from the Venturi tube (13) is introduced;
a first distribution plate (20) mounted at one side in the chamber (14) and including a plurality of flow paths (21) configured to mix, disperse, and diffuse air and the gas;
a second distribution plate (30) mounted on the chamber (14) to be spaced a predetermined distance from the first distribution plate (20) to prevent a backfire phenomenon, and including a slot (31) configured to mix, disperse, diffuse, and discharge air and the gas in an inward direction of an edge thereof;
a flame forming plate (40) mounted on the second distribution plate (30) and configured to disperse, diffuse, and discharge a mixture of the air and gas discharged from the slot (31) through a plurality of tiny holes; and
a mesh (50) mounted on the flame forming plate (40) and configured to diffuse combustion heat of the mixture discharged through the tiny holes.

### Claim 2 (depends on 1)

The portable gas stove of claim 1, further comprising a bracket (60) mounted between the body (10) and the chamber (14) and configured to block and minimize heat of the chamber (14) from being transferred to the body (10).

### Claim 3 (depends on 2)

The portable gas stove of claim 2, further comprising a gas pressure regulator (80) connected to a nozzle of a gas container (C) to maintain a pressure of a gas in a predetermined range and including an injection port (81) connected to the inlet (11) so that the gas flows and a spindle (82) configured to adjust a discharge rate of the gas to be in a predetermined range.

### Claim 4 (depends on 3)

The portable gas stove of claim 3, further comprising a holding clip (63) provided under the bracket (60), elastically deformed by elasticity, and configured to fix the gas pressure regulator (80) to a lower side of the body.

### Claim 5 (depends on 1)

The portable gas stove of claim 1, further comprising a protective cover (70) mounted between the body (10) and the mesh (50) to cover the chamber (14) and including a plurality of air holes (71) which are formed along a perimeter of the chamber (14) and through which air flows.

### Claim 6 (depends on 2)

The portable gas stove of claim 2, further comprising a protective cover (70) mounted between the body (10) and the mesh (50) to cover the chamber (14) and including a plurality of air holes (71) which are formed along a perimeter of the chamber (14) and through which air flows.
