Description:

BACKGROUND OF THE INVENTION

(1) Field of the Invention

The present invention relates to a portable flammable gas generating device which provides flammable mixture of hydrogen and oxygen.

(2) Description of the Prior Art

A conventional way to get flammable gas is natural gas which is supplied by the natural gas company and delivered via pipes connected between the users and the natural gas tank of the company. The natural gas can be dangerous because of carbon monoxide which can be produced when the combustion of the natural gas is not completed and such carbon monoxide is harmful to people. Another potential risk is that the natural gas is delivered at a high pressure in the pipe and once the pipe leaks, the gas is flammable. FIG. 6 shows a conventional flammable gas generating device which includes a hydrogen generating device 7 which is composed of an electrolytic tank 8 in which water is filled, a mixing tank 9 and a soldering gun 91 connected with the mixing tank 9. The hydrogen and oxygen are produced by the electrolytic processes to the water and the hydrogen and the oxygen are sent to the mixing tank 9. The mixture is flammable and can be used with the soldering gun 91.

However, the conventional energy generating device occupies a lot of space and heavy which is not convenient to be carried. Besides, the electrolytic process requires a lot of electric power which increase the cost of the alternative energy.

The present invention intends to provide a portable flammable gas generating device which is in a form of a casing in which a hydrogen source and an oxygen source are received. The hydrogen and the oxygen are mixed together with a coolant and the mixture is delivered to a gas burner for use for outdoor barbecue.
