NOVELTY - A system for producing hydrogen and oxygen mixture gases, comprises an electrode unit (20) which is formed of negative electrodes (25) and positive electrodes (26) and further includes first and second lines (21, 22); a mixture gas separation filter (50) which is installed in the interior of the electrolyte storage tank (10); and a first filter unit (70) which stores water for preventing the hydrogen and oxygen mixture gas.    USE - The system is used for producing hydrogen and oxygen mixture gases (claimed).    ADVANTAGE - The system can obtain economical advantages by increasing the amount of a mixture of hydrogen and oxygen gases as compared to an electric energy and at the same time combustion can be performed without an auxiliary gas such as propane. The system can secure a stable structure by eliminating a reverse combustion flame possibility. Nano particles are divided into negative electrodes and positive electrodes which produce hydrogen and oxygen bubbles, and water having very low vibrations is supplied for thus more effectively producing hydrogen and oxygen bubbles from electrodes, and effectively detach the produced bubbles. So, it is possible to enhance electrolyte efficiency, which can increase the amount of a mixture of hydrogen and oxygen gases as compared to the electric energy inputted, for thus obtaining economical advantages, and combustion can be performed without using an auxiliary fuel. Reverse burning of combustion flame can be prevented by adapting the first and second filter units, and a high purity gas mixture can be produced for thus implementing a more stable hydrogen and oxygen gas mixture production system.    DETAILED DESCRIPTION - A system for producing hydrogen and oxygen mixture gases, comprises an electrode unit (20) which is formed of negative electrodes (25) and positive electrodes (26) and further includes first and second lines (21, 22) connected with a lower side of the electrolyte storage tank (10), and a third line (23) for supplying the produced hydrogen and oxygen mixture gases to the electrolyte storage tank (10); a mixture gas separation filter (50) which is installed in the interior of the electrolyte storage tank (10) for separating the hydrogen and oxygen mixture gases from the electrolyte; a collection part (60) which is formed in an upper side of the mixture gas separation filter (50) for collecting the hydrogen and oxygen mixture gases which are separated by means of the mixture gas separation filter (50); a first filter unit (70) which stores water for preventing the hydrogen and oxygen mixture gas, which is inputted from the collection part (60), reverse-flow into the collection part (60); and a first gas line (75) for connecting the collection part (60) and the first filter unit (70).
