Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 2, an embodiment of the oxyhydrogen gas supply apparatus 2 according to the present invention includes a gas supply unit 3, a mixing unit 4 connected to the gas supply unit 3, and a mixing unit 5 connected to the gas supply unit 3 and the mixing unit 4. The gas supply unit 3 includes an electrolysis device 31, an oxygen supply line 32 communicating with the electrolysis device 31, a hydrogen supply line 33 communicating with the electrolysis device 31, and a back fire preventer 34 disposed between the electrolysis device 31 and the hydrogen supply line 33. The electrolysis device 31 has an electrolysis tank 311 for containing electrolyzed water, a plurality of electrode plates 312 soaked in the electrolyzed water in the electrolysis tank 311, and a power supply 313 electrically connected with the electrode plates 312 and controlled to be electrified. The electrode plate 312 can be charged by the power supply 313 to generate hydrogen and oxygen by electrolysis in the electrolyzed water. In the present embodiment, the flash back preventer 34 may be a water-sealed type or other structure, but not limited thereto.

The blending unit 4 includes a buffer tank 41 communicated with the oxygen delivery pipeline 32 of the gas supply unit 3, a flow regulating valve 42 communicated with the buffer tank 41 and capable of being controlled to regulate the output of oxygen, and a pressure relief valve 43 communicated with the buffer tank 41 and capable of regulating the pressure or detecting the pressure to discharge excessive oxygen from the buffer tank 41 to the outside. In the present embodiment, the flow regulating valve 42 is a needle valve structure, but not limited thereto. The mixing unit 5 includes a mixing tank 51 communicating with the hydrogen delivery pipe 33 of the gas supply unit 3 and the flow regulating valve 42 of the mixing unit 4, an output pipe 52 communicating with the mixing tank 51 and being controlled to output oxyhydrogen gas, and a detector 53 for detecting the oxygen ratio in the mixing tank 51 to control the flow regulating valve 42.

When the power supply 313 is turned on, the electrode plate 312 generates hydrogen and oxygen in a fixed ratio in the electrolytic cell 311 through electrolysis, then the hydrogen is delivered to the hydrogen delivery pipeline 33, and the oxygen is delivered to the oxygen delivery pipeline 32, the hydrogen delivery pipeline 33 and the oxygen delivery pipeline 32 can be connected to different heights of the electrolytic cell 311, so that the hydrogen and oxygen with different specific gravities can enter corresponding correct pipelines after being layered up and down, and certainly, the functions of respectively delivering the gases can be achieved through other devices or structural designs, and the method is not limited to the above-mentioned layered up and down manner. The hydrogen gas is fed into the mixing tank 51 after entering the hydrogen delivery pipeline 33, the oxygen gas is fed into the buffer tank 41 after entering the oxygen delivery pipeline 32, and the flow regulating valve 42 allows an appropriate flow of oxygen gas to enter the mixing tank 51 from the buffer tank 41 according to the setting, so that the hydrogen gas and the oxygen gas are mixed into the oxyhydrogen gas in a specific ratio, and finally the mixed oxyhydrogen gas is output outwards for use through the output pipeline 52. During the output process, the detector 53 will determine the oxygen ratio in the mixing tank 51 to regulate the flow regulating valve 42 in real time. The flashback arrestor 34 is used to prevent a flashback from extending into the electrolytic bath 311 and causing an explosion. The pressure relief valve 43 can detect the air pressure in the buffer tank 41, so that when the air pressure is too high, the excessive oxygen is directly discharged from the buffer tank 41 to the outside, thereby preventing the burst of the buffer tank 41 due to the too high air pressure.

The ratio of oxygen fed into the mixing tank 51 can be controlled by the flow regulating valve 42 to control the ratio of hydrogen and oxygen after mixing, so that the hydrogen and oxygen can be optimized for different purposes, for example, when the hydrogen is inhaled for health care, the hydrogen is preferably 75% to 79%, and the oxygen is preferably 25% to 21%, and the above ratio is favorable for human body absorption. When the ratio of hydrogen to oxygen is adjusted to 8:1 or other proper ratios, the tempering phenomenon can be avoided to improve the safety. When oxygen is not input (namely the proportion of hydrogen is 100 percent), the oxygen can be used for combustion supporting or air purification, and other purposes can be realized by adjusting the proportion according to industrial welding, sterilization or other purposes, so as to achieve the optimized effect. The above-mentioned ratio can be adjusted according to the actual situation, and is not limited to the above-mentioned disclosed ratio.

In summary, the present invention can control the flow rate of oxygen entering the mixing tank 51 through the flow regulating valve 42, so as to adjust the ratio between the hydrogen and the oxygen, so that the output hydrogen and oxygen can have an optimized ratio according to different applications, thereby achieving the purpose of the present invention.
