Abstract

Disclosed is a portable no-pump multi-fuel stove that may use gasoline and butane together. Butane gas is injected above gasoline in the fuel tank so that the butane gas is combusted at an initial ignition stage, thereby eliminating the need of preheating resulting from incomplete combustion of gasoline at an initial ignition stage in a conventional gasoline stove. Once a certain amount of butane is combusted, though butane is not supplied, gasoline is continuously inhaled, vaporized and injected by means of vapor pressure in the fuel tank and osmotic pressure of the inhaling member without any gasoline pressuring work. The nozzle is not easily separated but easily exchanged. The gas discharge hole is formed downward at one side of the fuel injection hole. The inhaling member is filled to a middle portion of the entire length of the preheating tube so that the stove has small and light structure.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a portable no-pump multi-fuel stove in which a gasoline injection hole is devised to have multi functions so as to enable injection of butane as well as gasoline and also to act as a check valve and a safety valve in combination.

[0003] In addition, a preheating tube installed to traverse an upper portion of a burner bowl has a dual structure so that a gas tube with small diameter is inserted into the preheating tube as a gas passage and an inhaling member is put into a space out of the preheating tube.

[0004] Thus, gas is injected into the preheating tube and fuel in a liquid state is injected out of the preheating tube. Multiple heat sinks are provided to an inner upper end of a fuel tank at intervals so that conductive heat of the burner bowl may directly heat the inner upper end of the fuel tank.

[0005] Thus, a pressure of the expanded gas allows fuel to be continuously injected ...
