[0005] The utility model aims at, for example, providing a gas supply system, which can regulate and control the flow and pressure of mixed gas, dilute the content of hydrogen and oxygen in the mixed gas, and has diversified functions and high safety.

[0006] The embodiment of the utility model can be realized as follows:

[0007] In the first aspect, the utility model provides a gas supply system, which comprises:

[0008] The hydrogen oxygen device comprises a water tank, an electrolytic cell and a humidification kettle, the water tank is communicated with the electrolytic cell, the electrolytic cell is communicated with the humidification kettle, the pressurizing device is communicated with the humidification kettle, and the humidification kettle is provided with a mixed gas outlet.

[0010] According to the above scheme, the plurality of components are integrated together through the shell, which is compact in structure, small in size and convenient to carry.

[0011] In an optional embodiment, the water tank is hung outside the shell and detachably connected with the shell.

[0012] According to the above scheme, the water tank can be separated from the shell in some scenarios where there is a limit on the storage space of the device, so that the volume of each part is reduced after being separated, and the two parts can be carried or stored independently, which is convenient and flexible to use.

[0013] In an optional embodiment, the pressurizing device comprises a compression fan and a gas conveying pipe, the air outlet of the compression fan is connected with the gas conveying pipe, and the gas conveying pipe is connected with the humidification kettle; the gas conveying pipe cooperates with the water tank to cool the gas flowing in the gas conveying pipe through the liquid in the water tank.

[0014] According to the above scheme, the gas pressurized by the compression fan is high-temperature and high-pressure gas, that is, after being pressurized by the compression fan, the gas not only increases in pressure, but also increases in temperature. When the pressurized gas is conveyed through the gas conveying pipe, the part of the gas exchanges heat with the liquid in the humidification kettle when passing through the humidification kettle, thereby reducing the temperature of the compressed gas.

[0015] In addition, when the gas pressurized by the compression fan is conveyed in the gas conveying pipe, the air inside the shell can exchange with the outside air due to the heat dissipation holes provided on the shell, so as to realize the cooling of the compressed gas in the gas conveying pipe through heat exchange with the air.

[0016] In an optional embodiment, part of the gas conveying pipe is arranged in the water tank and can directly contact the liquid in the water tank.

[0017] According to the above scheme, the gas conveying pipe is directly immersed in the liquid, the contact area between the gas conveying pipe and the liquid is large, the heat exchange area is large, the heat exchange effect is good, and the heat exchange efficiency is high.

[0018] In an optional embodiment, the pressurizing device further comprises a filter, and the filter is installed at the air inlet of the compression fan.

[0019] According to the above scheme, when the compression fan sucks in the external air for pressurization, the external air is first filtered by the filter. The filter can effectively remove dust, particulate matter and other solid impurities in the air, prevent these impurities from entering the compression fan, and reduce wear and blockage. At the same time, after the impurities in the air are filtered, the cleanliness of the external air is improved, the user is not easy to be infected when breathing, and the safety is improved.

[0020] In an optional embodiment, the hydrogen-oxygen generating device further comprises a water-gas separator, the electrolytic cell is communicated with the water-gas separator, and a liquid outlet of the water-gas separator is communicated with the water tank.

[0021] Based on the above scheme, in the process of preparing hydrogen and oxygen by the electrolytic cell, water is mixed in the hydrogen and oxygen, and before the hydrogen and oxygen are supplied to the user for breathing, the water in the hydrogen and oxygen is filtered out by the water-gas separator, so as to reduce the humidity and avoid the water level in the humidification pot rising sharply when the hydrogen and oxygen enter the humidification pot, thereby affecting the normal use of the humidification pot. Moreover, the humidity is reasonably controlled by the humidification pot, and the comfort of the user in inhaling is improved.

[0022] In an optional embodiment, the electrolytic cell has a hydrogen outlet and an oxygen outlet, the water-gas separator has a hydrogen separation chamber and an oxygen separation chamber, the hydrogen outlet is communicated with the hydrogen separation chamber, and the oxygen outlet is communicated with the oxygen separation chamber.

[0025] Based on the above scheme, the first air inlet can be communicated with the oxygen outlet of the electrolytic cell, the second air inlet can be communicated with the air outlet of the compressed air fan, and the third air inlet can be communicated with the hydrogen outlet of the electrolytic cell, and at the same time, the first air inlet and the third air inlet are immersed in the liquid in the humidifier. In this way, when the system is running, the hydrogen and oxygen generated in the electrolytic cell have relatively small flow, about 1-10L / min, which enters the two chambers in the body of the kettle from the bottom, and is humidified by the water bottom crossing humidification method. The method has good moderate water bubble rolling and low sound, the compressed air with a pressure of about 10KPA is input at the second air inlet, the flow is greater than that of oxygen and hydrogen, the airflow directly enters from the waterless space of the first chamber, and can enter the second chamber. In this process, the compressed air and the water bubbles formed by the oxygen entering the first air inlet roll together into a water-air waterfall type humidification, and then enters the second chamber, and then merges with the rolling water bubbles and water-air generated by the hydrogen input through the third air inlet and outputs from the mixed gas outlet. This humidification method is water waterfall type humidification, which saves the space of the humidification container and avoids bringing too much water to cause discomfort of breathing water droplets, so that the humidification of three types of gas and two types of humidification in two chambers in the humidifier is merged, and the hydrogen and oxygen are pressurized and diluted to meet the breathing flow demand and improve the safety.

[0026] In an optional embodiment, the gas supply system further comprises a mask or a head-mounted breathing chamber, both of which are communicated with the mixed gas outlet.

[0027] Based on the above scheme, the user can conveniently and reliably breathe by wearing the mask or the head-mounted breathing chamber.

[0029] In summary, the gas supply system provided by the present embodiment generates hydrogen and oxygen and guides them to the humidifier, mixes them with the air pressurized by the pressurizing device, and discharges the mixed gas after pressurization for the user to use. Since the air is pressurized and enters the humidifier, the pressure of the mixed gas can be adjusted, thereby adjusting the flow of the mixer to meet the flow demand of the user during breathing. At the same time, after the pressurized air enters the humidifier, it can dilute the hydrogen and oxygen, thereby reducing the content of hydrogen and oxygen, making the mixing ratio of hydrogen and oxygen outside the explosive range, and improving the safety in use.

Meanwhile, the pressurized air enters the humidifier 140, can dilute the hydrogen and oxygen, so that the content of the hydrogen and oxygen is reduced, the mixing ratio of the hydrogen and oxygen is outside the explosion range ratio, and the use safety is improved.

[0048] The following embodiments illustrate the details of the gas supply system of the application in an exemplary manner.

[0049] In the embodiment, the optional gas supply system comprises a hydrogen-oxygen generating device 100, a pressurizing device 200, a power supply device and an electric control board 500.

The power supply device provides electric energy for the whole system.

[0050] For reference Figures 1-2 In the embodiment, the optional hydrogen-oxygen generating device 100 comprises a casing 110, a water tank 120, an electrolytic cell 130, a humidifier 140 and a water-gas separator 150. The casing 110 is provided with heat dissipation holes, and can be further provided with a plurality of interfaces for connecting with various types of pipelines. An identifier can be arranged at each interface to facilitate knowing the function of each interface. For example, the interface can be used to connect with a pipeline to output the mixed gas, or the interface can directly separate a part of the pressurized gas of the pressurizing device 200 to be delivered into the face mask 300 or the head-mounted breathing chamber 400 to adjust the pressure. The water tank 120 can be hung outside the casing 110, and the water tank 120 and the casing 110 can be detachably connected. The water tank 120 can be detached from the casing 110 as needed to facilitate carrying and storing. The electrolytic cell 130 and the humidifier 140 can be installed in the casing 110. The water-gas separator 150 can be connected with the water tank 120 and installed at the top of the water tank 120. The water outlet of the water-gas separator 150 directly communicates with the water tank 120, and the water-gas separator 150 can separate the water in the hydrogen and oxygen.

[0051] It should be noted that the electrolytic cell 130 can adopt a known structure. In the embodiment, the detailed structure and working principle of the electrolytic cell 130 are not described in detail to avoid repetition. When the electrolytic cell 130 is used, water can be electrolyzed to form hydrogen and oxygen, and the hydrogen and oxygen are discharged from the hydrogen outlet and the oxygen outlet of the electrolytic cell 130 respectively and delivered into the water-gas separator 150 for separation operation without interference, thereby achieving good water-gas separation effect.

[0052] In addition, the water-gas separator 150 can adopt a known structure, and in the present embodiment, the detailed structure and working principle of the water-gas separator 150 are not described in detail to avoid repetition. When the water-gas separator 150 is used, water in the oxygen and hydrogen can be separated, the amount of water entering the humidifier 140 can be reduced, and the normal use of the humidifier 140 can be avoided. In addition, the number of water-gas separators 150 can be one or more, and the hydrogen and oxygen can be introduced into different water-gas separators 150 for separation, or the hydrogen and oxygen can be introduced into one water-gas separator 150 for separation using two independent chambers. In addition, when the hydrogen and oxygen are separated respectively, a plurality of water-gas separators 150 can be connected in series for separation to improve the water-gas separation effect.

[0053] For example, in one embodiment, when the number of water-gas separators 150 is one, the water-gas separator 150 has a hydrogen separation chamber and an oxygen separation chamber, the hydrogen outlet is communicated with the hydrogen separation chamber, and the oxygen outlet is communicated with the oxygen separation chamber.

[0054] Please refer to Figure 5 Optionally, the humidifier 140 includes a kettle body 141 and a partition plate 142, the partition plate 142 is installed in the kettle body 141 and divides the kettle body 141 into a first chamber 143 and a second chamber 144 in communication, the first chamber 143 and the second chamber 144 are arranged left and right, and the partition plate 142 can be provided with a communication hole 1421 communicating the first chamber 143 and the second chamber 144, the number of communication holes 1421 can be one or more, and when the humidifier 140 stores liquid, the liquid level is lower than the height of the communication hole 1421. At the same time, the kettle body 141 is provided with a first gas inlet 145, a second gas inlet 146 and a third gas inlet 147, and a mixed gas outlet 148 is arranged on the kettle body 141, the first gas inlet 145 and the second gas inlet 146 are communicated with the first chamber 143, and the third gas inlet 147 and the mixed gas outlet are communicated with the second chamber 144. Among them, the first gas inlet 145 and the third gas inlet 147 are located at the bottom of the kettle body 141, the first gas inlet 145 can be used to introduce oxygen, and the third gas inlet 147 can be used to introduce hydrogen. The second gas inlet 146 and the mixed gas outlet 148 are located above the liquid level, and the second gas inlet 146 can be used to introduce compressed gas.

[0055] It should be understood that, when the system is running, due to the relatively small flow of hydrogen and oxygen generated in the electrolytic cell 130, about 1-10 L / min, the water bottom crossing humidification method is used to humidify the two chambers entering the kettle body 141 from the bottom, which has moderate water bubble rolling and low sound, and the compressed air with a pressure of about 10 KPA is input at the second air inlet 146, the flow is greater than that of oxygen and hydrogen, the airflow directly enters from the waterless space of the first chamber 143, and can enter the second chamber 144, in the process, the compressed air and the water bubble rolling formed by the oxygen entering the first air inlet 145 are combined into a water-air waterfall type humidification, and then enter the second chamber 144, and then merge with the rolling water bubble water-air generated by the hydrogen input through the third air inlet 147 and output from the mixed gas outlet, this humidification method is water waterfall type humidification, which saves the humidification container space and avoids bringing out too much water to cause discomfort of breathing water droplets, so that the humidification of three types of gas and two types of humidification of two chambers in the humidification kettle 140 is merged, and the hydrogen and oxygen are pressurized and diluted to meet the breathing flow demand and improve safety.

[0056] In this embodiment, the optional pressurizing device 200 includes a compressed air fan 210, a gas conveying pipe 220 and a filter 230. The compressed air fan 210 and the filter 230 are both installed in the machine shell 110, one end of the gas conveying pipe 220 is communicated with the air outlet of the compressed air fan 210, and the other end is communicated with the second air inlet 146. The filter 230 is communicated with the air inlet of the compressed air fan 210, and the filter 230 can filter the gas entering the compressed air fan 210. Part of the pipe section of the gas conveying pipe 220 is located in the machine shell 110, and part of the pipe section is arranged in the water tank 120, and the pipe section located in the water tank 120 can be submerged in the liquid in the water tank 120. That is, during the operation of the compressed air fan 210, the temperature of the pressurized gas increases, and when the pressurized gas is conveyed through the gas conveying pipe 220, part of the gas exchanges heat with the liquid in the humidification kettle 140 when passing through the humidification kettle 140, thereby reducing the temperature of the compressed gas. Since part of the gas conveying pipe 220 is submerged in the liquid and has a large contact area with the liquid, the heat exchange efficiency is high. In addition, since the machine shell 110 is provided with heat dissipation holes, the air inside the machine shell 110 can exchange with the outside air, thereby achieving the temperature reduction of the compressed gas in the gas conveying pipe 220 through heat exchange with the air.

[0057] It should be understood that, since the pipeline is connected to the water tank for cooling the compressed air, the fan system configured in the traditional industry can be omitted, thereby saving space volume, reducing noise and reducing manufacturing cost.

[0058] Optionally, the power supply device can be one or more, and the pressurizing device 200 and the electrolytic cell 130 can be independently configured with a power supply device, which is flexible to use.

[0059] Please refer toFigure 3 、 Figure 4 and Figure 6 In this embodiment, the air supply system further comprises a mask 300 or a head-mounted breathing chamber 400, both of which are connected to the mixed gas outlet 148. The user can breathe conveniently and reliably by wearing the mask 300 or the head-mounted breathing chamber 400.

[0060] It should be understood that when the user uses the head-mounted breathing chamber 400, a branch of the outlet of the compressor fan 210 can be provided, which can be directly connected to the head-mounted breathing chamber 400 to adjust the pressure of the head-mounted breathing chamber 400. If the branch is not needed, a valve can be provided to close it.

[0061] It should be noted that the mask 300 or the head-mounted breathing chamber 400 is connected to the mixed gas outlet through a tee joint 600, and a one-way exhalation valve 700 is installed on the tee joint 600. During breathing, the exhaust gas is directly discharged from the one-way exhalation valve 700.

[0062] It should be noted that the electric control board 500 can be integrated with a Bluetooth module and a wireless communication module, etc., so that the air supply system can be connected to a smart terminal to realize intelligent control. The smart terminal can be, but is not limited to, a mobile phone, a tablet computer, etc.

[0063] The air supply system provided in this embodiment can adjust the pressure of the mixed gas, thereby adjusting the flow of the mixer, to meet the demand of the user for the flow during breathing. At the same time, after the pressurized air enters the humidification kettle 140, the hydrogen and oxygen can be diluted, thereby reducing the content of hydrogen and oxygen, so that the mixing ratio of hydrogen and oxygen is outside the explosive range, and the use safety is improved.

[0064] In addition, in the prior art, the oxygen generator, the hydrogen-oxygen generator, and part of the large civilian micro-pressure oxygen cabin are used for "diffusion inhalation method", which leads to a decrease in effective inhalation concentration, especially a low oxygen partial pressure and hydrogen partial pressure (without a closed pipeline inhalation system). The hospital hyperbaric oxygen chamber is a professional mask type closed inhalation system, which realizes high partial pressure but has a huge weight, up to 40 tons for a 30-person cabin. The air supply system provided in this embodiment combines the hydrogen-oxygen generator with the micro-pressure air, and whether it matches the eye-nose mask or the head cover cabin system, it adopts a closed inhalation method rather than a "diffusion method". In this way, the oxygen partial pressure of the micro-pressure large oxygen cabin is achieved, and the hydrogen inhalation is increased. The overall volume is small, the weight can be controlled within a few kilograms, and it is convenient to carry. At the same time, the manufacturing cost is greatly reduced, so that more people can enjoy health care, rehabilitation, and even treatment, and the use range is wide.

[0065] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
