[0048] The water tank 2 is fixedly arranged in the shell 1, and a water inlet 4 is arranged on the upper portion of the water tank 2; a screw cap is arranged on the water inlet 4, and water can be added through the water inlet after the screw cap is opened.

[0049] The electrolytic device 9 is arranged in the shell 1, and a water inlet, an electrolytic device oxygen outlet 10 and an electrolytic device hydrogen outlet 11 are arranged on the electrolytic device 9; the water inlet of the electrolytic device 9 is connected with the water outlet of the water tank 2 through a water conveying pipeline.

[0050] The hydrogen-oxygen mixing device is connected with the hydrogen outlet and the oxygen outlet of the electrolytic device 9, respectively; a gas supply pipeline 21 adapted to discharge the mixed hydrogen and oxygen is arranged in the hydrogen-oxygen mixing device; the gas supply pipeline 21 is provided with a mixed gas conveying terminal 24 at the end thereof, and the hydrogen-oxygen mixed gas is supplied to the mouth and nasal cavity of a patient through the mixed gas conveying terminal 24.

[0051] The water quality detection device 7 is arranged on the water conveying pipeline and is used for detecting the water quality condition in the water conveying pipeline.

[0052] The drainage device is arranged on the water conveying pipeline and is used for discharging water when the water quality condition is poor.

[0053] The output end of the water quality detection device 7 is connected with the input end of the power intelligent control system 18, and the controlled ends of the drainage device and the electrolytic device 9 are connected with the output ends of the power intelligent control system 18; the power intelligent control system 18 is used for controlling whether the drainage device is operated according to the transmission information of the water quality detection device 7; the power intelligent control system 18 comprises a controller, a power supply and a touch display screen, and the information can be displayed through the touch display screen.

[0054] The water quality detection device 7 can detect the water quality in the water delivery pipeline in real time when hydrogen and oxygen are prepared, and feed the detected water quality information to the power intelligent control system 18, which compares the water quality information with the internally set water quality information value; if the power intelligent control system 18 judges that the water quality is poor at this time, the power intelligent control system 18 controls the drainage device to act, and the drainage device directly discharges the water in the water delivery pipeline; if the power intelligent control system 18 judges that the water quality at this time meets the standard, no control instruction is sent to the drainage device, and the water in the water delivery pipeline directly enters the electrolytic device 9 for electrolysis. The water entering the electrolytic device 9 is monitored and controlled, so that the quality of the water entering the electrolytic device 9 is ensured, the problem of hydrogen-oxygen mixed gas doped with impurities caused by electrolysis of poor-quality water is avoided, and the treatment of patients is more beneficial.

[0055] More specifically, the water delivery pipeline includes a first water delivery main pipeline, a second water delivery main pipeline and a water delivery branch pipeline. The first water delivery main pipeline is connected to the water outlet of the water tank 2. One end of the second water delivery main pipeline is connected to the first water delivery main pipeline, and the other end of the second water delivery main pipeline is connected to the water inlet of the electrolytic device 9.

When the equipment is not used for a long time or the water quality is poor and the water needs to be replaced, the electromagnetic drainage valve is opened to empty the water in the water tank and the pipeline.

[0057] A circulating water pump 8 is arranged on the second water delivery main pipeline, and the controlled end of the circulating water pump 8 is connected to the output end of the power intelligent control system 18. When the circulating water pump 8 is started, the water in the second water delivery main pipeline can be pumped into the electrolytic device 9.

When the water quality is poor, the power intelligent control system 18 controls the drainage valve 6 to act and perform the drainage operation; when the water quality is good, the power intelligent control system 18 controls the circulating water pump 8 to act and perform the water inlet operation of the electrolytic device.

[0058] A resin filter device 5 is arranged on the first water delivery main pipeline, which is used to filter the water discharged from the water tank 2 to increase the purification effect of the water. In this embodiment, the water discharged from the water tank is purified before the water quality is detected.

[0059] The electrolysis device 9 comprises an electrolytic cell, a positive electrode and a negative electrode, and the controlled ends of the positive electrode and the negative electrode are connected to the output end of the power intelligent control system 18, and the power intelligent control system 18 can control whether the electrolysis device 9 performs electrolysis action.

[0060] The hydrogen outlet 11 of the electrolysis device is connected to the inside of the hydrogen-oxygen mixing device through a hydrogen conveying pipe, and the hydrogen conveying pipe is provided with a hydrogen observation window 13 and / or a hydrogen gas-liquid separator 12 and / or a first one-way valve flame arrester 15.

[0061] The hydrogen observation window 13 is used for observing the condition of the prepared hydrogen, and a first groove is formed in the shell 1, and the condition of the hydrogen observation window 13 can be observed through the first groove.

[0062] In order to more conveniently observe the generation condition of the hydrogen, the hydrogen observation window 13 is provided with an indicating lamp. The hydrogen generated by the water electrolysis of the electrolysis device is displayed in the form of bubbles in the hydrogen observation window 13 through the conveying pipeline and under the light of the indicating lamp, and the working condition of the hydrogen production equipment is easy to observe.

[0063] The first one-way valve flame arrester 15 plays the role of a one-way valve, so that the hydrogen flows in the hydrogen conveying pipe in one direction, and also has a fireproofing effect.

[0064] The oxygen outlet 10 of the electrolysis device is connected to the inside of the hydrogen-oxygen mixing device through an oxygen conveying pipe, and the oxygen conveying pipe is provided with an oxygen observation window and / or an oxygen gas-liquid separator 19 and / or a second one-way valve flame arrester 16.

[0065] The oxygen observation window is used for observing the condition of the prepared oxygen, and a second groove is formed in the shell 1, and the condition of the oxygen observation window can be observed through the second groove.

[0066] In order to more conveniently observe the generation condition of the oxygen, the oxygen observation window is provided with an indicating lamp. The oxygen generated by the water electrolysis of the electrolysis device is displayed in the form of bubbles in the oxygen observation window through the conveying pipeline and under the light of the indicating lamp, and the working condition of the oxygen production equipment is easy to observe.

[0067] The hydrogen gas-liquid separator 12 in the application is arranged on the hydrogen gas conveying pipe, can separate the hydrogen liquid mixture gas into gas and liquid, ensure the dryness of the supplied hydrogen gas, and ensure the dryness of the hydrogen gas conveying pipe, so that the hydrogen gas conveying pipe will not be blocked by the accumulation of liquid in the pipe. The oxygen gas-liquid separator 19 is arranged on the oxygen gas conveying pipe, can separate the oxygen liquid mixture gas into gas and liquid, ensure the dryness of the supplied oxygen gas, and ensure the dryness of the oxygen gas conveying pipe, so that the oxygen gas conveying pipe will not be blocked by the accumulation of liquid in the pipe. The hydrogen-oxygen mixing device is used for separating the input hydrogen gas and oxygen gas into gas and liquid, to ensure the dryness of the output mixed gas. The application separates the hydrogen gas and oxygen gas into gas and liquid once when generating the hydrogen gas and oxygen gas, and separates the hydrogen gas and oxygen gas into gas and liquid once again after mixing the hydrogen gas and oxygen gas, thereby better ensuring the dryness of the output mixed gas.

[0068] The liquid discharge end of the hydrogen gas-liquid separator 12 and / or the oxygen gas-liquid separator 19 and / or the hydrogen-oxygen mixing device is connected with the water tank 2 through the backwater pipe 22, realizes the recovery of the liquid separated by the hydrogen gas-liquid separator 12 and / or the oxygen gas-liquid separator 19 and / or the hydrogen-oxygen mixing device, realizes the recycling of the liquid, and avoids the waste caused by direct discharge.

[0069] The gas supply pipe 21 is provided with a water-blocking filter membrane 20 and / or a one-way explosion-proof pressure regulating flame arrester 17.

[0070] The water-blocking filter membrane 20 is arranged on the gas supply pipe 21 of the hydrogen-oxygen mixing device, and is used for preventing the liquid in the hydrogen-oxygen mixing device from entering the gas supply pipe 21, and further ensures the dryness of the mixed gas. The water-blocking filter membrane 20 can filter the hydrogen-oxygen mixed gas, can filter water molecules, heavy metals and impurities, and improves the purity of the hydrogen-oxygen gas.

[0071] The one-way explosion-proof pressure regulating flame arrester 17 can accurately adjust the pressure of the hydrogen-oxygen mixed gas conveying, and also has the function of reducing static electricity, thereby reducing the safety hidden trouble. For example, Figure 4As shown, the one-way explosion-proof pressure-regulating flame arrester 17 specifically comprises an anti-static sensor 170, an air inlet port 171, a one-way valve bead 172, a corrugated explosion-proof flame arrester core 173, and a flow pressure regulating valve 174. The air inlet port 171 of the one-way explosion-proof pressure-regulating flame arrester is in communication with the gas supply pipeline 21, and the hydrogen-oxygen mixed gas can only pass through in one direction. The air outlet port 175 is connected to the mixed gas delivery terminal 24 for the patient to inhale. The anti-static sensor 170 is mounted on the shell of the one-way explosion-proof pressure-regulating flame arrester to prevent static electricity. The controlled end of the anti-static sensor 170 is connected to the output end of the power intelligent control system 18. The one-way valve bead 172 is arranged inside the air inlet port 171 of the one-way explosion-proof pressure-regulating flame arrester, and can only pass through the medium in one direction and be sealed in the opposite direction. The corrugated explosion-proof flame arrester core 173 is arranged inside the one-way explosion-proof pressure-regulating flame arrester 17. The corrugated explosion-proof flame arrester core 173 has many corrugated small hole channels. When the flame passes through the flame arrester core device and enters the many corrugated small hole channels, it will become several small flames in contact with the channel wall, so that the flame temperature is reduced below the ignition point, thereby preventing the flame from spreading. The flow pressure regulating valve 174 is arranged on the internal passage of the air inlet port 171. The flow pressure regulating valve 174 can measure the flow and pressure data, and has the function of adjusting the flow and pressure. The controlled end of the flow pressure regulating valve 174 is connected to the output end of the power intelligent control system 18.

[0072] The process of the filtered mixed hydrogen-oxygen gas passing through the one-way explosion-proof pressure-regulating flame arrester 17 is as follows: The filtered mixed hydrogen-oxygen gas passes through the one-way valve bead 172 from the delivery pipeline, enters the corrugated explosion-proof flame arrester core 173, and is divided into the flow pressure regulating valve pipeline after passing through the corrugated small hole. The flow pressure regulating valve 174 is controlled by the power intelligent control system, and can accurately adjust the pressure of the hydrogen-oxygen mixed gas delivery. Finally, the gas outlet port 175 flows to the mixed gas delivery terminal 24 for the patient to absorb.

[0073] The water tank 2 is internally provided with a water level detection sensor 3 for detecting the water level. The output end of the water level detection sensor 3 is connected to the input end of the power intelligent control system 18.

[0074] The shell 1 is provided with a water level observation window 23, through which the water level in the water tank 2 can be directly observed.

[0075] The shell 1 is internally further provided with intelligent sensing double fans and other electronic components. The intelligent sensing double fans can better dissipate heat from the whole device. The shell 1 is provided with a heat dissipation hole 25 corresponding to the position of the intelligent sensing double fans.

[0076] The working process of the present application is as follows:

[0077] S1. Pure water or distilled water is added into the water tank 2 through the water inlet 4, and the water level detection sensor 3 detects the amount of water added. There is an alarm function to prompt if the water is too much or too little. When the water level detection sensor 3 detects that the water is lacking or overfilled, the entire device cannot start normally. The electrolytic cell is easily damaged if the water is lacking, and the hydrogen and oxygen gas cannot be smoothly transported if the water is overfilled.

[0078] S2. The water in the water tank 2 is transported to the first water delivery main pipeline and filtered by the resin filter device 5. The filtered water is transported to the second water delivery main pipeline and the water delivery branch pipeline. The water quality detection device 7 detects the quality of the filtered water and provides a "excellent, good, poor" three-function prompt. When the water quality detection device 7 detects that the water quality is "poor", it feeds back the detection information to the power intelligent control system 18, and the circulating water pump 8 and the electrolytic device 9 do not start. At the same time, the power intelligent control system 18 controls the drain valve 6 to open and drain the water. When the water quality detection device 7 detects that the water quality is "excellent" or "good", it feeds back the detection information to the power intelligent control system 18, and the power intelligent control system 18 controls the circulating water pump 8 and the electrolytic device 9 to start normally. At this time, the drain valve 6 is in a closed state.

[0079] The "excellent, good, poor" three water quality prompts can be displayed on the power intelligent control system 18.

[0080] S3. The filtered excellent water is transported to the electrolytic cell by the circulating water pump 8.

[0081] The electrolyzed hydrogen liquid mixture gas enters the hydrogen delivery pipe through the electrolytic device hydrogen outlet 11 and is transported along the hydrogen delivery pipe. The hydrogen liquid mixture gas enters the hydrogen gas-liquid separator 12 for gas-liquid separation. The separated hydrogen gas is transported to the first one-way valve flame arrestor 15 through the pipeline, and then enters the mixed gas-liquid separator 14. The separated electrolytic water returns to the water tank 2 through the water return pipeline 22.

[0082] The electrolyzed oxygen liquid mixture gas enters the oxygen delivery pipe through the electrolytic device oxygen outlet 10 and is transported along the oxygen delivery pipe. The oxygen liquid mixture gas enters the oxygen gas-liquid separator 19 for gas-liquid separation. The separated oxygen gas is transported to the second one-way valve flame arrestor 16 through the pipeline, and then enters the mixed gas-liquid separator 14. The separated electrolytic water returns to the water tank 2 through the water return pipeline 22.

[0083] S4. The hydrogen and oxygen mixture gas is collected in the mixed gas-liquid separator 14 and is subjected to gas-liquid separation in the mixed gas-liquid separator 14. After separation, the hydrogen and oxygen mixture gas enters the gas supply pipeline 21, is filtered through the water-blocking filter membrane 20, and finally flows to the mixed gas delivery terminal 24. The mixed gas is delivered to the patient's oral cavity through the mixed gas delivery terminal 24 for the patient to absorb.

[0084] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated.
