The oxygen gas generator 13 comprises a molecular sieve filter 131 to filter the air and generate the oxygen gas, which is called a first oxygen gas hereafter. Besides, the oxygen gas generator 13 is coupled to the gas mixing tube 15 to dilute the hydrogen gas by inputting the first oxygen gas into the gas mixing tube 15 to form a mixed gas.

[0056] In this embodiment, the mixed gas generating device combined with oxygen gas generator 1 further comprises a hydrogen concentration detector 18 coupled with the gas mixing tube 15 to detect a gas volume concentration in the gas mixing tube 15. In practice, the hydrogen concentration detector 18, the electrolytic cell 12, and the oxygen gas generator 13 can be coupled to the controller 14 of mixed gas generating device combined with oxygen gas generator 1. The controller 14 can respectively adjust the hydrogen gas generation production quantity of the electrolytic cell 12 and the oxygen gas production quantity of the oxygen generator 13, according to the hydrogen concentration detected by the hydrogen concentration detector 18, so as to dilute and adjust the hydrogen concentration of the mixed gas in the gas mixing tube 15 to be less than a predetermined value for human inhalation. In practice, the predetermined value can be 1% to 7.5%, but not limited to, the inhalation of hydrogen concentration depends on user's body.

[0057] In this embodiment, the mixed gas generating device combined with oxygen gas generator 1 further comprises the flow meter 19. The flow meter 19 coupled to the gas mixing tube 15 to detect the flow rate value of the mixed gas in the gas mixing tube 15. In practice, the flow meter 19 also can be coupled to the controller 14 as mentioned above, the controller 14 can respectively adjust the hydrogen gas generation volume of the electrolytic cell 12 and the oxygen gas generation volume of the oxygen generator 13 according to the flow rate value of the mixed gas detected by the flow meter 19. Furthermore, the mixed gas generating device combined with the oxygen gas generator 1 generates the mixed gas at the predetermined flow value for the user inhalation. In practice, the predetermined flow value of the mixed gas can be 1.0 L/min to 6.0 L/min or above 6.0 L/min. In an embodiment, the predetermined flow value of the mixed gas can be between 3.0 L/min to 6.0 L/min.

[0058] Please refer to FIG. 2 and FIG. 3. FIG. 2 illustrates a partial graph of the mixing generating device with oxygen gas generator according to another embodiment of the present invention. FIG. 3 illustrates a cross-section of a mixing generating device with oxygen gas generator in FIG. 2. Please notice that the FIG. 2 shows a partial of the mixing generating device with oxygen gas generator, and other parts are omitted for brevity, such as casing or other units within the casing. As shown in FIG. 2, the mixing generating device with oxygen gas generator 3 comprises the integrated water tank module 30, the electrolytic cell 32, the oxygen gas generator 34, and the atomization/volatile gas mixing tank 36. Furthermore, the integrated water tank module 30 comprises the sink, the gas mixing tube 35, the hydrogen port 300, the oxygen port 302, and the water port 304. Wherein, the hydrogen port 300 is coupled to the gas mixing tube 35 within the integrated water tank module 30, and the oxygen port 302 and water port 304 are coupled to the sink within the integrated water tank module 30. The hydrogen port 300, the oxygen port 302, and the water port 304 of the integrated water tank module 30 can be separately coupled to hydrogen gas output duct 320. The oxygen gas output duct 322 and the water input duct 324 of the electrolytic cell 32 are to respectively receive the hydrogen gas and the oxygen gas generated by the electrolytic cell 32 to supplement the electrolyzed water in the electrolytic cell 32. Furthermore, the second oxygen output of the electrolytic tank 32 may be mixed with little residual electrolyzed water, and the residual electrolyzed water remains in the water tank of the integrated water tank module 30 for recycling.

[0059] In this embodiment, the oxygen gas generator 34 further comprises the air conduit 340, the molecular sieve oxygen generator 342, the oxygen gas conduit 344, and the air pump 347. In practice, the molecular sieve filter unit 342 can be formed by a plurality of molecular sieves in the container, such as a molecular sieve filter to filter out oxygen gas in the air. Specifically, the molecular sieves adsorb gases other than oxygen gas into the air, and only allow oxygen gas to pass through. In this embodiment, the air conduit 3 is coupled to the air pump 347 and the molecular sieve oxygen generator 342; the oxygen gas conduit 344 is coupled to the molecular sieve oxygen generator 342 and the gas mixing tube 35 of the integrated sink module 30. The air pump 347 sucks in air from the environment and passes the air through the air conduit 340 to the molecular sieve filter unit 342. The joint position between the supplemental gas conduit 306 and the gas mixing tube 35 has an angle, and the joint position must form an arc lead angle. In practice, the angle may be a sharp angle below 90 degrees, and a better angle range in the design is between 25 and 45 degrees. When the air conduit 340 transmits the air sucked by the air pump 347 to the molecular sieve filter unit 342, the molecular sieve filter unit 342 filters out the first oxygen gas in the air, and outputs the first oxygen gas to the supplemental gas conduit 306 through the oxygen gas conduit 344. The supplemental gas conduit 306 is designed with an angle so that the first oxygen gas in the oxygen gas conduit 344 enters into the gas mixing tube 35 to dilute the hydrogen gas in the gas mixing tube 35. The oxygen gas generator can be installed outside of the hydrogen generating device or inside it.

[0060] In this embodiment, the atomization/volatile gas mixing tank 36 is coupled to the gas mixing tube 35 to receive the mixed gas including the hydrogen gas and oxygen gas. The atomization/volatile gas mixing tank 36 generates an atomizing gas to be mixed with the mixed gas to form a healthy gas, wherein the atomizing gas is one or a combination selected from a group consisting of water vapor, anatomized drops, and essential oils. In one embodiment, the atomization/volatile gas mixing tank 36 comprises an oscillator. The oscillator atomizes water, anatomized drops and essential oils in the atomization/volatile gas mixing tank 36 through oscillation to generate atomized gas, and to mix the gas with the atomized gas to form a health gas. The atomization/volatile gas mixing tank 36 can be selectively turned on or off according to users' needs to provide healthcare gas mixed with atomized gas or mixed gas (such as the hydrogen gas diluted by the second oxygen gas) for users to inhale.

[0061] Please refer to FIG. 2 and FIG. 4. FIG. 4 illustrates a cross-section of the electrolytic cell in FIG. 2. In this embodiment, the electrolytic cell 32 can be an ion membrane electrolytic cell. In practice, it is not limited to an ion membrane electrolytic cell. This present invention may also use other types of electrolytic cells.

[0062] As shown in FIG. 4. The electrolytic cell 32 comprises an ion membrane 321, a cathode chamber 325, an anode chamber 326, a first side S1, a second side S2, a hydrogen gas output duct 320, and an oxygen gas output duct 322. The ion membrane 321 is disposed between the first side S1 and the second side S2; the cathode 325 is disposed between the ion membrane 321 and the first side S1; and the anode 326 is disposed between the ion membrane 321 and the second side S2. Wherein the area of the first side S1 and the cathode 325 located is called the cathode chamber 3201, and the area of the second side S2 and the anode electrode 326 located is called the anode chamber 3202. In order to better express the corresponding positions for the cathode chamber 3201 and the anode chamber 3202, the corresponding positions are shown by a dotted line in the FIG. 3. The hydrogen gas output duct 320 extends from between the ion membrane 321 and the first side S1 to the second side S2 and penetrates the second side S2, and the oxygen gas output duct 322 extends between the ion membrane 321 and the second side S2, and penetrates the second side S2. The cathode chamber generates the hydrogen gas and the anode chamber generates the second oxygen gas when the electrolytic cell electrolyzes water. In practice, the second oxygen gas contains oxygen, and may also contain the ozone that is not conducive to human inhalation, so the second oxygen gas and hydrogen gas are outputted separately. In this embodiment, the hydrogen gas and the second oxygen gas generated by the electrolytic cell 32 electrolyzing water are outputted from the second side S2 of electrolytic cell 32 respectively through the hydrogen gas output duct 320 and oxygen gas output duct 322. Furthermore, the electrolytic cell 12 may comprise the water input duct 324 coupled to the anode chamber 3202 and penetrate the second side S2, to receive water to supplement the electrolyzed water lost after electrolysis. Therefore, the water input duct 324, the hydrogen gas output duct 320, and the oxygen gas output duct 322 are disposed on the second side S2 of the electrolytic cell 32.

[0063] In this embodiment, the hydrogen gas output duct 320, the oxygen gas output duct 322 and the water input duct 324 are disposed on one side of the anode chamber 3202 of the electrolytic cell 32 (the second side, S2), but it is not limited to this. In one embodiment, the hydrogen gas output duct 320, the oxygen gas output duct 322 and the water input duct 324 can be disposed on one side of the cathode chamber 3201 of the electrolytic cell 32 (the first side S1).

[0064] The mixing generating device with oxygen gas generator of the present invention can also include a backflow preventer device (The figure is not shown), disposed between the oxygen gas generator and the gas mixing tube, configured to prevent gas in the gas mixing tube from flowing through the oxygen generator. In practice, the backflow preventer device can be a flame arrester. The flame arrester comprises the non-return valve; therefore, the gas can pass through in one direction only. In another one of embodiment, the backflow preventer device is disposed on the gas mixing tube and is close to the oxygen generator, so that the first oxygen gas in the oxygen gas duct can flow to the gas mixing tube through the backflow preventer device, and the gas in the gas mixing tube cannot flow into the oxygen gas duct. Because the gas mixing tube may contain inflammable gas (such as hydrogen), the backflow preventer device can prevent other gas in the gas mixing tube from returning back to the oxygen gas duct, thereby preventing the gas unfortunately ignited from spreading to the oxygen generator and then improving safety. The location of the backflow preventer device is not limited to the place mentioned above. In one embodiment, the backflow preventer device can be disposed on the oxygen gas duct of the oxygen generator and close to the gas mixing tube. In another one of embodiment, the backflow preventer device is disposed between the gas mixing tube and the atomizing gas/volatile gas mixing tank, and is disposed at the entrance of the atomizing gas/volatile gas mixing tank, to prevent the gas of the atomizing gas/volatile gas mixing tank from backflowing to the gas mixing tube. In one embodiment, the flame arrester can contain at least one of a metal mesh filter and a corrugated filter. The metal mesh filter can be the stainless steel or the copper mesh with a diameter of 0.23-0.315 mm and composed of multiple layers. The corrugated filter can be stainless steel, copper-nickel alloy, aluminum, and aluminum alloy which can be used to prevent the violent flame of deflagration and withstand the corresponding thermal and mechanical effects. The flame arrestor is used to block off the fire from flowing to the flame arrestor, thereby isolating the two spaces to avoid the fire spreading from one side of the flame arrester to the other side, which can cause the fire to spread through the gas flow path and make an explosion.

[0065] In practice, the mixed gas generating device combined with an oxygen generator of the aforementioned embodiments further comprises a control panel coupled to the above-mentioned of the controller, thereby controlling the electrolytic cell and the oxygen generator and adjusting the hydrogen volume concentration and the flow rate of the mixed gas output.

[0066] The mixing generating device with the oxygen gas generator of the present invention not only can be the aforementioned embodiments, but also can be other forms. Please refer to FIG. 5. FIG. 5 illustrates a schematic diagram of a mixed gas generating device 4 according to an embodiment of the present invention. As shown in FIG. 5, the difference between this embodiment and the aforementioned embodiment is that the oxygen generator 43 is coupled to hydrogen generating device 40 from the outside of the hydrogen generating device 40. In this embodiment, the hydrogen generating device 40 comprises the casing, and the casing includes an accommodating space for the electrolytic cell, the integrated sink module, the atomization/volatile gas mixing tank, and the gas mixing tube mentioned above. The oxygen generator 43 is disposed on the outside of the hydrogen generating device 40, comprising the molecular sieve filtering unit 432, the air pump 437 and the oxygen gas conduit 44 mentioned above (the molecular sieve filtering unit 432 and the air pump 437 are represented by the dashed lines in figure). The oxygen conduit 44 passes through the casing of the hydrogen generating device 40 from the outside of the hydrogen generating device 40 and coupled to the gas mixing tube located inside the casing of the hydrogen generating device 40, and the gas mixing tube is coupled to the atomization/volatile gas mixing tank. Therefore, the oxygen generator 43, through the molecular sieve filter unit 432, inputs the first oxygen generated by the air pump 437 into the gas mixing tube to dilute the hydrogen gas to form a mixed gas.

[0067] Please refer to FIG. 6. FIG. 6 illustrates a schematic diagram of a mixed gas generating device according to another embodiment of the present invention. As shown in FIG. 6, the difference between this embodiment and the aforementioned embodiment is that the gas mixing tube 55 and the oxygen generator 53 are both coupled to the hydrogen generating device 50 from the outside of the hydrogen generating device 50. In this embodiment, the hydrogen generating device 50 comprises a casing, and the casing includes an accommodating space for the electrolytic cell, the integrated sink module, and the atomization/volatile gas mixing tank mentioned above. The atomization/volatile gas mixing tank comprises a gas port, and the gas mixing tube 55, from the outside of the casing of the hydrogen generating device 50, is coupled to the gas port of the atomization/volatile gas mixing tank, the oxygen generating device 53, and the breathing mask 59. The oxygen generator 53 is disposed on the outside of the hydrogen generating device 50, and can comprise the molecular sieve filtering unit 532, the air pump 537 mentioned above (the figure is represented by a dashed line). The electrolytic cell of the hydrogen generating device 50 generates hydrogen gas or hydrogen-containing gas and outputs the hydrogen gas or hydrogen-containing gas to the gas mixing tube 55 through the atomization/volatile gas mixing tank. The oxygen generator 53, through the molecular sieve filter unit 532, inputs the first oxygen generated by the air pump 537 into the gas mixing tube 55 to form a mixed gas, so that users can inhale the mixed gas through the breathing mask 59.

[0068] Please refer to FIG. 7 and FIG. 8. FIG. 7 illustrates an explode diagram of a hydrogen gas generating device according to embodiment of the present invention. FIG. 8. illustrates a schematic diagram with different visual angles of a hydrogen gas generating device according in FIG. 7. As shown in FIG. 7 and FIG. 8., in the embodiment, the hydrogen gas generating device 60 comprises the electrolytic cell (the figure is not shown), the water tank 602, the humidification cup 603, the integrated flow channel 604, the condensing filter devices 605, hydrogen water cup 606 and the atomization/volatile gas mixing tank 607. The electrolytic cell can be an electrolytic cell of electrode type contained in the water tank 602, and receive the electrolyzed water from the water tank 602 for being electrolyzed to generate hydrogen-containing gas. The humidification cup 603 is vertically stacked on the water tank 602; the integrated flow channel 604 is vertically stacked on the humidification cup 603; and the condensing filter devices 605 is contained in the accommodation space of the integrated flow channel 604.

[0069] The condensing filter devices 605 is used to filter the hydrogen gas and comprises the condensing flow channel 6051. In practice, the condensing filter devices 605 can be implanted to the integrated flow channel 604 and can be drawn out from the side of the integrated flow channel 604 for replacement without disassembling the entire gas generating device 60. The humidification cup 603 comprises the humidification space (the figure is not shown) and the connected space 6031. The humidification space comprises the supplemental water and can be used to humidify the hydrogen-containing gas. The connected space 6031 is coupled to the water tank 602 and the integrated flow channel 604; therefore, the hydrogen generated by the electrolytic cell disposed in the water tank 602 enters into the condensing flow channel 6051 of the condensing filter device 605. The hydrogen water cup 606 can be used to contain drinking water and input the hydrogen gas into the drinking water to form hydrogen-containing water. The integrated flow channel 604 comprises the enter gas flow channel 6041, the exit gas channel 6042, and the gas connecting flow channel 6043. Wherein the enter gas flow channel 6041 and the exit gas flow channel 6042 can be selectively coupled to the hydrogen water cup 606, and the gas connecting flow channel 6043 can be selectively coupled to the enter gas flow channel 6041 and the exit gas channel 6042. The atomization/volatile gas mixing tank 607 comprises the exit gas channel 6042 to receive the hydrogen gas, and produces the atomizing gas mixing with hydrogen gas to form a health-care gas. In additional, the humidification cup 603, the condensing filter device 605, the atomization/volatile gas mixing tank 607, and the hydrogen water cup 606 can be engaged with or coupled to the integrated flow channel device 604. Furthermore, the hydrogen gas generating device 60 also comprises the aforementioned flame arrestor (the figure is not shown), located at the entrance of the atomizing gas/volatile gas mixing tank 607.

[0070] Therefore, the hydrogen gas generated by the electrolytic cell leaves the water surface of the water tank 602 and quickly enters into the connected space 6031 of the humidification cup 603. Then the hydrogen gas flows through the connected space 6031 of the humidification bottle 603, the condensation flow channel 6051 of the condensation filter device 605, and the enter gas flow channel 6041, the exit gas flow channel 6042, and the atomization/volatile gas mixing tank 607 of the integrated flow channel 604. Wherein, the hydrogen gas can selectively flow through the hydrogen water cup 606. However, it should be understood that the above-mentioned flow direction of the hydrogen-containing gas is one of the embodiments of the hydrogen gas generator E of the present invention, those skilled in the art can adjust the order of the components according to their needs, and it is not limited to this.

[0071] In this embodiment, the hydrogen gas generating device 60 comprises the molecular sieve filter unit 632 and the air pump 673, and the molecular sieve filter unit 632 is used to filter the air sucked by the air pump 637 and generate oxygen. The gas mixing tube 65 can be connected to the exit gas channel 6042 of the integrated flow channel device 604 and receive the hydrogen output from the exit gas channel 6042, and the gas mixing tube 65 can be connected to the molecular sieve filter unit 632 and the air pump 637. The functions of the molecular sieve filter unit 632 and the air pump 637 of this embodiment are substantially the same as the functions of the molecular sieve filter unit and the air pump of the aforementioned embodiment, so that it is not repeated herein. The gas mixing tube 65 can receive the hydrogen gas output from the exit gas channel 6042, and the oxygen gas generates by the molecular sieve filter unit 632 to form a mixed gas. The atomizing/volatile gas mixing tank 607 of the hydrogen gas generating device 60 can be connected to the gas mixing tube 65 and receive the mixed gas in the gas mixing tube 65, and the atomizing/volatile gas mixing tank 607 can generate the atomizing gas and the mixed gas to form the health care gas. The oxygen generator 63 can be disposed outside the casing 601 of the hydrogen gas generating device 60, or disposed inside the casing 601.

[0072] Please refer to FIG. 9. FIG. 9 illustrates a schematic diagram of a mixed gas generating device according to another embodiment of the present invention. In this embodiment, the hydrogen gas generating device 60 comprises the casing 601; the gas mixing tube 65 is disposed in the casing 601 of the hydrogen gas generating device 60, and the oxygen generator 63 is disposed outside the hydrogen gas generating device 60. The oxygen gas generating device 63 comprises the aforementioned molecular sieve filter unit 632, the air pump 637, and an oxygen conduit 64 (the molecular sieve filter unit 632 and the air pump 637 in the figure are represented by dashed lines). The oxygen conduit 64 of the oxygen generator 63 passes through the casing 601 of the hydrogen generator 60 from the outside of hydrogen generator 60, and is coupled with the gas mixing tube 65 in the casing 601 of the hydrogen generator 60. Therefore, the oxygen generator 63, through the molecular sieve filter unit 632, inputs the first oxygen generated by the air pump 437 into the gas mixing tube 65 to dilute the hydrogen gas to form a mixed gas. In another embodiment, the gas mixing tube and the oxygen generator both are disposed outside of the hydrogen gas generating device. The atomization/volatile gas mixing tank is coupled to the exit gas channel of the integrated flow channel device, and the gas mixing tube is coupled to the atomizing/volatile gas mixing tank.

[0073] In the above-mentioned embodiments, the mixed gas generating device or system comprise the oxygen generator such as molecular sieve filter to mix the hydrogen gas generated by the electrolytic cell with the oxygen gas generated by the oxygen generator to form the mixed gas for users to inhale. However, the mixed gas generating device can also be connected to an oxygen generator or an oxygen supply which is configured outside of the mixed gas generating device, such as the oxygen supply for the patient in hospital, so as to extend the use of the mixed gas generating device or system in the present invention.

[0074] Please refer to FIG. 10. FIG. 10 is a functional block diagram illustrating a mixed gas generating device connected with breathing tube and an oxygen gas generator according to an embodiment of the present invention. As shown in FIG. 10, the mixed gas generating device connected with the breathing tube 1′ comprises an electrolytic cell 12, a gas mixing tube 15 and the breathing tube 13′. The electrolytic cell 12 is configured for electrolyzing water to generate a gas comprising hydrogen or a hydrogen gas. The gas mixing tube 15 is coupled to the electrolytic cell 12 and the atomized/volatile gas mixing tank 16 for transporting the gas comprising hydrogen or the hydrogen gas generated by the electrolytic cell 12 to the atomized/volatile gas mixing tank 16. The breathing tube 13′ is coupled to the gas mixing tube 15 and the oxygen gas generator 2, and is configured to receive the oxygen gas provided by the oxygen gas generator 2 and then inputs the oxygen to the gas mixing tube 15, so as to dilute the hydrogen gas or the gas comprising hydrogen in the gas mixing tube 15 to form the mixed gas. The oxygen gas inputted by the breathing tube 13′ is called as the first oxygen hereafter.

[0075] In this embodiment, the mixed gas generating device connected with breathing tube 1 further comprises a hydrogen concentration detector 18. The hydrogen concentration detector 18 is coupled to the gas mixing tube 15 to detect a hydrogen volume concentration in the gas mixing tube 15. In practice, the hydrogen concentration detector 18 and the electrolytic cell 12 can be coupled to a controller 14 of the mixed gas generating device connected with breathing tube 1′. The controller 14 can respectively adjust the hydrogen gas generating quantity of the electrolytic cell 12 according to the hydrogen concentration detected by the hydrogen concentration detector 18, so as to dilute and adjust the hydrogen concentration of the mixed gas in the gas mixing tube 15 to be less than a predetermined value for human inhalation. The predetermined value can be 1%, 2%, 3%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7% or 7.5%. However, the hydrogen concentration of the mixed gas is not limited to the above values but can be determined by the requirements of the user's body.

[0076] In this embodiment, the mixed gas generating device connected with breathing tube 1′ further comprises a flow meter 19. The flow meter 19 is coupled to the gas mixing tube 15 to detect the flow rate value of the mixed gas in the gas mixing tube 15. In practice, the flow meter 19 also can be coupled to the controller 14. The controller 14 can adjust the quantity of the hydrogen gas generated by the electrolytic cell 12 according to the flow rate value of the mixed gas detected by the flow meter 19, so that the mixed gas generating device connected with breathing tube 1′ generates the mixed gas with a predetermined flow value for the user to inhale. In practice, the predetermined flow value of the mixed gas can be 1.0 L/min, 2.0 L/min, 3.0 L/min, 4.0 L/min, 5.0 L/min, 6.0 L/min or above 6.0 L/min. In an embodiment, the predetermined flow value of the mixed gas can be between 3.0 L/min to 6.0 L/min.

[0077] Please refer to FIG. 11a, FIG. 11b, FIG. 12 and FIG. 13. FIG. 11a is a schematic diagram illustrating a mixed gas generating system according to an embodiment of the present invention. FIG. 11b is a schematic diagram illustrating a mixed gas generating system according to another embodiment of the present invention. FIG. 12 is a partial schematic diagram illustrating the mixed gas generating device connected with the breathing tube 30′ in FIG. 11a. FIG. 13 is a sectional diagram illustrating the mixed gas generating device 30′ in FIG. 11a. It should be noted that FIG. 12 and FIG. 13 show a part of the mixing generating device connected with the breathing tube 30′, and the other parts, such as the casing or other units within the casing, are omitted from these figures for sake of brevity. In this embodiment, the mixed gas generating device connected with breathing tube 30′ further comprises an integrated water tank module 31, the electrolytic cell 32, the breathing tube 33′, and the atomized/volatile gas mixing tank 36. The mixed gas generating device connected with breathing tube 30′ is coupled to an oxygen generating device 38. Furthermore, the integrated water tank module 31 comprises a water tank and a gas mixing tube 35. One end of the breathing tube 33′ is coupled to the gas mixing tube 35, and a part of breathing tube 33′ extends to the outside of the casing of the mixed gas generating device connected with the breathing tube 30′ to be coupled to the oxygen generating device 38, so as to input the first oxygen generated by oxygen generating device 38 through the breathing tube 33′ into the gas mixing tube 35 of the mixed gas generating device connected with breathing tube 30′ to dilute the hydrogen gas to form a mixed gas. In practice, the oxygen generating device 38 can be the equipment for hospital or medical use (as shown in FIG. 11a, the oxygen equipment 38 corresponding to the hospital bed 4), the oxygen bottle or the ventilator 38′ (as shown in FIG. 11b). The breathing tube 33′ can be the oxygen tube for hospital or medical use, or the output tube of the ventilator.

[0078] As show in FIG. 12 and FIG. 13. The integrated water tank module 31 further comprises a hydrogen gas port 310, an oxygen gas port 312, and a water port 314. The hydrogen gas port 310 coupled to the gas mixing tube 35 within the integrated water tank module 31 and the oxygen gas port 312, the water port 314 are coupled to the sink within the integrated water tank module 31. The hydrogen port 310, the oxygen port 312, and the water port 314 of the integrated water tank module 31 can be separately coupled to the hydrogen gas output duct 320, the oxygen gas output duct 322 and the water input duct 324, configured to respectively receive the hydrogen gas and the oxygen gas generating by the electrolytic cell 32, and output the water to supplement the electrolyzed water in the electrolytic cell 32. The detailed descriptions of the hydrogen gas output duct 320, the oxygen gas output duct 322 and the water input duct 324 of the electrolytic cell 32 will be made later. Furthermore, the integrated water tank module 31 comprises a supplement gas port 316 coupled to the breathing tube 33′ and the gas mixing tube 35. The joint position between the supplement gas port 316 and the gas mixing tube 35 has an angle, and the joint position must form an arc lead angle. In practice, the angle may be a sharp angle below 90 degrees, and a better angle range in the design is between 25 and 45 degrees. The supplemental gas port 316 is designed with an angle so that the first oxygen in the breathing tube 33′ enters into the gas mixing tube 35 to dilute the hydrogen in the gas mixing tube 35.

[0079] In addition, the gas mixing tube within the integrated water tank module 31 is coupled to the atomized/volatile gas mixing tank 36, so that the hydrogen gas outputted from the electrolytic cell 32 enters into the gas mixing tube within the integrated water tank module 30 and then further goes into the atomized/volatile gas mixing tank 36. In practice, the oxygen gas (called as the second oxygen in the following) generated by the electrolytic cell 32 thought the oxygen gas output duct 322 and the oxygen port 312 is directly outputted to the integrated water tank module 31, and is discharged to the atmosphere. Furthermore, the second oxygen outputted by the electrolytic tank 32 may be mixed with little residual electrolyzed water, and the residual electrolyzed water remains in the water tank of the integrated water tank module 30 for recycling.

[0080] Please refer to FIG. 10 and FIG. 13. The mixed gas generating device connected with the breathing tube 1′ of the present invention further comprises a backfire preventer 17 disposed between the gas mixing tube 15 and the breathing tube 13′. As shown in FIG. 13, in this embodiment, the backfire preventer 37 is disposed in the breathing tube 33′ and is configured to prevent gas in the gas mixing tube 15 from flowing to the breathing tube 33′. The backflow preventer 37 can be the flame arrester. The flame arrester comprises the non-return valve; therefore, the gas can pass through in one direction only. In this embodiment, the backflow preventer 37 is disposed on the side of the gas mixing tube 35 and is close to the breathing tube 33′; therefore the first oxygen in the breathing tube 33′ can flow to the gas mixing tube 35 through the backflow preventer 37, and the gas in the gas mixing tube 35 cannot flow into the breathing tube 33′. Because the gas mixing tube 30 may contain an inflammable gas (such as hydrogen), the backflow preventer 37 can prevent other gas in the gas mixing tube 35 from returning back to the breathing tube 33′, to reduce or prevent the unfortunately ignited gas from spreading to the oxygen generator, thereby improving safety.

[0081] The location of the backflow preventer in this present invention can be the location described in the aforementioned embodiment, it can also be disposed in other locations. In another one of the embodiments, the backflow preventer device is disposed between the gas mixing tube and the atomized/volatile gas mixing tank, and is disposed at the entrance of the atomized/volatile gas mixing tank, to prevent the gas in the atomized/volatile gas mixing tank from backflowing to the gas mixing tube.

[0082] In this embodiment, the atomized/volatile gas mixing tank is coupled to the gas mixing tube to receive the mixed gas comprising hydrogen gas and oxygen gas. The atomized/volatile gas mixing tank 36 generates an atomized gas mixed with the mixed gas to form a healthy gas, wherein the atomized gas is one or a combination selected from a group consist of water vapor, atomized drops, and essential oils. In one embodiment, the atomized/volatile gas mixing tank 36 comprises the oscillator; the oscillator atomizes water, anatomized drops and essential oil in the atomized/volatile gas mixing tank 36 by oscillating to generate the atomized gas, and mixes the mixed gas with the atomized gas to form a health gas. According to a user's needs, the atomized/volatile gas mixing tank 36 can be selectively turned on or off to provide healthcare gas mixed with atomized gas or mixed gas (the hydrogen gas diluted by the second oxygen gas) for users to inhale.

[0083] In practice, the mixed gas generating device connected with breathing tube in the aforementioned embodiments can further comprise a control panel coupled to the above-mentioned controller, thereby controlling the electrolytic cell and adjusting the hydrogen volume concentration and the output flow rate value of the mixed gas.

[0084] Please refer to FIG. 14. FIG. 14 is a schematic diagram illustrating a mixed gas generating system according to an embodiment of the present invention. As shown in FIG. 14, the differences between this embodiment and the aforementioned embodiment are that the gas mixing tube 55, the backfire preventer 57, and the breathing tube 53′ are coupled to the hydrogen generating device 50 from the outside of the hydrogen generating device 50, and the breathing tube 53′ is coupled to the oxygen generating device 58 corresponding to the hospital bed 4. In this embodiment, the hydrogen generating device 50 comprises a casing, and the casing comprises an accommodating space for accommodating the electrolytic cell, the integrated sink module and the atomized/volatile gas mixing tank mentioned above. The atomized/volatile gas mixing tank comprises a gas port, and the gas mixing tube 55 is coupled to the gas port of the atomized/volatile gas mixing tank disposed outside of the casing of the hydrogen generating device 50, the breathing tube 53′, and the breathing mask 59 of the hydrogen generating device 50. The breathing tube 53′ is coupled to the gas mixing tube 55 and the oxygen generating device 58, and the backfire preventer 57 is disposed in the side of the gas mixing tube 55 and close to the breathing tube 53′. The electrolytic cell of the hydrogen generating device 50 generates hydrogen or gas comprising hydrogen and outputs hydrogen or gas comprising hydrogen to the gas mixing tube 55 through the atomized/volatile gas mixing tank. The oxygen generator 58 generates the first oxygen, and the first oxygen is inputted to the gas mixing tube 55 through the breathing tube 53′ to form the mixed gas. Then, the user can inhale the mixed gas through the breathing mask 59.

[0085] Please refer to FIG. 15. FIG. 15 is a schematic diagram illustrating a mixed gas generating system 6 according to another embodiment of the present invention. The internal structure of the mixed gas generating system 6 can refer to that in FIGS. 7 and 8. However, the difference between the internal structure of the mixed gas generating system 6 with the internal structure in FIGS. 7 and 8 is that the mixed gas generating system 6 does not have the molecular sieve filtering unit and the air pump. The other portions in the mixed gas generating system 6 are substantially the same as those in FIGS. 7 and 8, and then they would not be described again.

[0086] In this embodiment, the gas mixing tube 65 can be coupled to the exit gas channel 6042 of the integrated flow channel device 604 to receive the hydrogen gas outputted by the exit gas channel 6042. The gas mixing tube 65 is further coupled to the breathing tube 63′ to receive the oxygen generated by oxygen generating device. Furthermore, the gas mixing tube 65 is configured to mix the hydrogen gas and the oxygen gas. In this embodiment, the hydrogen gas generating device 60 comprises the casing 601; the gas mixing tube 65 is disposed in the casing 601 of the hydrogen gas generating device 60; and the oxygen generating device 68 is disposed outside the hydrogen gas generating device 60. The breathing tube 63′ is coupled to the oxygen generating device 68 and the gas mixing tube 65 in the casing 601 of the hydrogen generator 60 by passing through the casing 601 of the hydrogen generator 60 from the outside of hydrogen generator 60. Therefore, the oxygen generated by the oxygen generating device 68 through the breathing tube 63′ into the gas mixing tube 65 to dilute the hydrogen gas to form a mixed gas. In addition, the atomized/volatile gas mixing tank 607 of the hydrogen generator 60 can receive hydrogen and oxygen in the gas mixing tube 65, and generate the atomized gas to mixed with hydrogen and oxygen to form the mixed gas. The functions of the atomized/volatile gas mixing tank of this embodiment are substantially the same as the functions of the atomized/volatile gas mixing tank of the aforementioned embodiment, which are not repeated herein. In another embodiment, the gas mixing tube and the oxygen generating device both are disposed outside of the hydrogen gas generating device. The atomized/volatile gas mixing tank is coupled to the exit gas channel of the integrated flow channel device, and the gas mixing tube is coupled to the atomizing/volatile gas mixing tank

[0087] In the summary, the mixing generating device with oxygen gas generator of the present invention is capable of generating oxygen gas by the oxygen gas generator and mixing the oxygen gas with the hydrogen gas produced by the electrolytic cell to dilute the hydrogen gas. The oxygen gas is mixed with the hydrogen gas to generate a mixed gas with a certain concentration of hydrogen gas for the patients with lung diseases to inhale, thus alleviating symptoms and reducing the burden on the lungs. In addition, the oxygen gas inputted by the oxygen gas generator makes the mixed gas have a higher oxygen concentration that is suitable for the patients with damaged lungs who requires high oxygen concentrations. Furthermore, the mixed gas produced by the device of the present invention may be mixed with the atomization gas with healing effects to form a healthy gas for human inhalation. Moreover, the device of the present invention can prevent the backflow of gas by backfire device, thereby improving safety. Therefore, the mixed gas generating device combined with oxygen gas generator of the present invention can provide gas with multiple effects at the same time, which improves the symptoms of patients with lung diseases and also can be used for general healthcare.
