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.

SUMMARY OF THE INVENTION

The present invention relates to a flammable gas generating device that includes a mixing tank including an inner space. An output pipe, a hydrogen input pipe connected to a hydrogen source, an oxygen input pipe connected to an oxygen source and a coolant pipe connected to a coolant source are respectively connected to the mixing tank and in communication with the inner space. Hydrogen and Oxygen are mixed in the mixing tank and sent out via an output pipe to be burned.
The primary object of the present invention is to provide a flammable gas generating device that is compact in size and provides mixture of hydrogen and oxygen, the mixture can be sent to a burner.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 to 4, the flammable gas generating device of the present invention comprises a casing 2 having a top cover 28 pivotably connected to a top of the casing 2 and a handle 21 is connected to the top cover 28 so that the casing 2 can be conveniently carried. A sensor unit 22 composed of a thermometer 221 and a level gauge 222 is connected to a side of the casing 2. A receptacle 24 is connected to the casing 2 and located away from the sensor unit 22. A plurality of apertures 23 are defined through the wall of the casing 2 and located beneath the receptacle 24. A control panel 14 is connected to the casing 2 and a through hole 26 defined through the casing 2 through which an output pipe 112 as shown in FIG. 5 extends. A separation board 27 is received in the casing 2 and defines an inner space of the casing 2 into an upper space and a lower space.
A mixing tank 11 is located at the lower space and includes an inner space 111. The output pipe 112 is connected with the mixing tank 11 and extends through the through hole 26 so as to deliver the mixture of the flammable gas to a burner 3 a shown in FIG. 5.
A hydrogen source 12 is located in the upper space and has a hydrogen input pipe 121 connected thereto. An oxygen source 13 has an oxygen input pipe 131 connected thereto and a coolant pipe 15 is located in the upper space and connected to a coolant source. The hydrogen input pipe 121, the oxygen input pipe 131 and the coolant pipe 15 are respectively connected to the mixing tank 11, and the hydrogen source 12, the oxygen source 13 and the coolant source are respectively connected with the control panel 14. The user may check the conditions of mixture by lights of the control panel 14. A plurality of ventilation holes 25 are located on two sides of the casing 2 and a plurality of casters 29 are connected to an underside thereof.
A receptacle 24 is connected to the casing 2 and located away from the sensor unit 22, and the receptacle 24 is connected with the oxygen source 13 which can be driven by AC current when needed.
The mixing tank 11 has an inner space 111 and a tubular member 113 is received in the mixing tank 11 and defines the inner space 111 into a first space 114 outside of the tubular member 113 and a second space 115 within the tubular member 113. The tubular member 113 includes a filter 116 located in communication between the first and second spaces 114, 115 so that the hydrogen, the oxygen and the coolant are mixed and filtered before entering the second space 115. The mixture is pure and includes less foreign objects. The output pipe 112 communicates with the second space 115 so as to be sent the mixture to the burner 3 via the output pipe 112.
