[0003] In related technologies, hydrogen-oxygen generators are mainly controlled by manually opening and closing the valve at the outlet. This causes the internal pressure of the hydrogen-oxygen generator to fluctuate significantly, and manual operation is cumbersome and prone to errors. Utility Model Content

[0004] The embodiments of this application provide a hydrogen-oxygen generator that can improve the technical problems of large fluctuations in the internal pressure of the hydrogen-oxygen generator and the cumbersome and error-prone manual operation.

[0011] The controller is connected to the pressure detection device, the connecting valve, and the power module. The controller is used to control the opening and closing of the connecting valve according to the detection data of the pressure detection device. The controller is also used to control the voltage and / or current output by the power module to the electrolytic cell.

[0016] In one embodiment, the pressure detection element includes a pressure sensor connected to the gas-liquid separator and electrically connected to the controller.

[0021] The beneficial effects of the embodiments of this application are as follows:

[0022] In the embodiments of this application, a pressure detection device can detect the pressure inside the gas-liquid separator. The pressure detection device can transmit the detection data to the controller, allowing the controller to control the opening and closing of the connecting valve based on the detection data. When the pressure inside the gas-liquid separator is determined to be greater than a preset value, the controller can control the connecting valve to open, allowing the gas inside the gas-liquid separator to be discharged through the connecting valve. When the pressure inside the gas-liquid separator is not greater than the preset value, indicating that the pressure inside the gas-liquid separator is insufficient, the control valve controls the connecting valve to close, ensuring that the gas-liquid separator will only discharge gas when the pressure inside the gas-liquid separator is greater than the preset value. This prevents large fluctuations in the internal pressure of the hydrogen-oxygen generator. Furthermore, it achieves automatic control of the opening and closing of the connecting valve, eliminating the need for manual operation, simplifying the operation of the hydrogen-oxygen generator, and helping to reduce the error rate.

[0023] Meanwhile, the controller can control the voltage and / or current output from the power module to the electrolyzer.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application.

[0030] The following is combined Figures 1 to 4 Describe the hydrogen-oxygen generator of this application.

[0031] According to embodiments of this application, such as Figure 1As shown, the hydrogen-oxygen generator includes an electrolytic cell 1, a gas-liquid separator 2, a connecting valve 3, a power module 4, a pressure sensor 5, and a controller 6. The gas inlet of the gas-liquid separator 2 is connected to the gas outlet of the electrolytic cell 1. The gas inlet of the connecting valve 3 is connected to the gas outlet of the gas-liquid separator 2 and is connected to the electrolytic cell 1. The power module 4 is used to supply power to the electrolytic cell 1 and is connected to the gas-liquid separator 2. The pressure sensor 5 is used to detect the pressure inside the gas-liquid separator 2. The pressure sensor 5, the connecting valve 3, and the power module 4 are all connected to the controller 6. The controller 6 is used to control the opening and closing of the connecting valve 3 according to the detection data of the pressure sensor 5. The controller 6 is used to control the voltage and / or current output from the power module 4 to the electrolytic cell 1.

[0032] According to the hydrogen-oxygen generator of this application embodiment, water is stored in the electrolytic cell 1, and the power module 4 can supply power to the electrolytic cell 1, enabling the electrolytic cell 1 to electrolyze water to produce hydrogen and oxygen. The gas generated in the electrolytic cell 1 enters the gas-liquid separator 2 after passing through the gas outlet of the electrolytic cell 1 and the gas inlet of the gas-liquid separator 2 in sequence. The gas-liquid separator 2 can store the gas. When the connecting valve 3 is in the open state, the gas in the gas-liquid separator 2 can flow out of the gas-liquid separator 2 through the connecting valve 3. When the connecting valve 3 is in the closed state, the gas in the gas-liquid separator 2 cannot flow out of the gas-liquid separator 2 through the connecting valve 3.

[0033] The pressure inside the gas-liquid separator 2 can be detected by the pressure detection device 5. The pressure detection device 5 can transmit the detection data to the controller 6, so that the controller 6 can control the opening and closing of the connecting valve 3 according to the detection data of the pressure detection device 5. When it is determined that the pressure inside the gas-liquid separator 2 is greater than the preset value, the controller 6 can control the connecting valve 3 to open, so that the gas inside the gas-liquid separator 2 can be discharged through the connecting valve 3. When the pressure inside the gas-liquid separator 2 is not greater than the preset value, it means that the pressure inside the gas-liquid separator 2 is insufficient, and the control valve controls the connecting valve 3 to close. This ensures that the gas-liquid separator 2 will only discharge gas when the pressure inside the gas-liquid separator 2 is greater than the preset value, which can prevent large fluctuations in the internal pressure of the hydrogen-oxygen generator. Moreover, it realizes automatic control of the opening and closing of the connecting valve 3, eliminating the need for manual operation, simplifying the operation of the hydrogen-oxygen generator, and helping to reduce the error rate.

[0034] Meanwhile, the controller 6 can control the voltage and / or current output from the power module 4 to the electrolytic cell 1. That is, the controller 6 can control the gas production of the electrolytic cell 1 by controlling the power module 4. It can adjust the gas production and gas production rate of the hydrogen-oxygen generator according to actual needs, thereby improving the intelligence level of the hydrogen-oxygen generator.

[0035] It is understandable that controlling the opening and closing of the connecting valve 3 can refer to switching the connecting valve 3 between two states: fully open and fully closed. Controlling the opening and closing of the connecting valve 3 can also refer to controlling the degree of opening of the connecting valve 3. In other words, the controller 6 can adjust the opening of the connecting valve 3 through negative feedback based on changes in the internal pressure of the gas-liquid separator 2, so that the pressure value of the gas-liquid separator 2 remains within the set range and is more stable.

[0036] In some examples, the air inlet of the gas-liquid separator 2 is located at the bottom of the gas-liquid separator 2, and the air outlet of the gas-liquid separator 2 is located at the top of the gas-liquid separator 2.

[0037] Understandably, by electrically connecting the power module 4 and the controller 6, the controller 6 can control the output of the power module 4. This allows users to set the required hydrogen-oxygen flow rate and volume based on different usage scenarios and needs, according to the actual gas consumption. Furthermore, by controlling the opening and closing of the connecting valve 3 based on the detection data from the pressure sensor 5, and adjusting the parameters of the controller 6, the preset value can be changed, achieving automatic adjustment of the set pressure. This reduces cumbersome manual operation, maximizes equipment utilization, and lowers power consumption.

[0038] Understandably, by detecting the pressure inside the gas-liquid separator 2 through the pressure detection device 5, the controller 6 can control the connecting valve 3 to close when the pressure inside the gas-liquid separator 2 is not greater than the preset value. This prevents the pressure inside the gas-liquid separator 2 from being too low, ensuring the pressure balance of the hydrogen-oxygen generator and avoiding accidents such as damage to the membrane of the electrolyzer 1 due to pressure imbalance, thereby improving the stability of the system.

[0039] In some embodiments, such as Figure 2 As shown, the hydrogen-oxygen generator also includes a control component 7, which is electrically connected to the controller 6, allowing the user to control the hydrogen-oxygen generator through the control component 7.

[0040] It is understood that the user can input corresponding control commands to the controller 6 through the control component 7, and the controller 6 will control the operation of components such as the connecting valve 3 and / or the power module 4 according to the control commands, so that the user can control the hydrogen-oxygen generator through the control component 7. The user can set the opening conditions of the connecting valve 3 and the gas production of the electrolyzer 1 and other system parameters according to actual needs and actual conditions.

[0041] Specifically, such as Figure 3 As shown, the control unit 7 includes a touch screen 71, which is electrically connected to the controller 6.

[0042] Understandably, users can input commands via touchscreen 71, which can then transmit the commands to controller 6, enabling controller 6 to control the operation of the hydrogen-oxygen generator according to the commands.

[0043] It should be noted that the control component 7 is only used as an example here and is not specifically limited. That is, the control component 7 can also be any other suitable component, such as buttons, voice input modules, etc.

[0044] In some embodiments, such as Figure 3 As shown, the hydrogen-oxygen generator also includes a safety valve 8, which is connected to the gas-liquid separator 2. The safety valve 8 is used to depressurize the gas-liquid separator 2 when the internal pressure of the gas-liquid separator 2 is greater than a preset value.

[0045] Understandably, the pressure detection device 5 will monitor the internal pressure of the gas-liquid separator 2 in real time and transmit the detection data to the controller 6. When the controller 6 determines that the internal pressure of the gas-liquid separator 2 exceeds the preset pressure value based on the detection data of the pressure detection device 5, the controller 6 will control the hydrogen-oxygen generator to stop producing gas, that is, control the power module 4 to stop supplying power to the electrolysis cell 1, so as to avoid the internal pressure in the gas-liquid separator 2 being too high.

[0046] When abnormal situations occur, such as the controller 6 failing to control the hydrogen-oxygen generator to stop producing gas or the connecting valve 3 malfunctioning, causing the internal pressure of the gas-liquid separator 2 to continue to rise after exceeding the preset pressure value, the safety valve 8 can automatically release pressure when the internal pressure of the gas-liquid separator 2 exceeds a certain level. This can prevent the internal pressure of the gas-liquid separator from increasing and ensure the safety of the hydrogen-oxygen generator.

[0047] In some embodiments, at least one of the controller 6, the control component 7, and the connecting valve 3 is electrically connected to the power module 4, which supplies power to at least one of the controller 6, the control component 7, and the connecting valve 3.

[0048] Understandably, power module 4 can supply power to at least one of controller 6, control component 7, and connecting valve 3, enabling them to function properly. In other words, power module 4 can supply power not only to electrolyzer 1 but also to at least one of controller 6, control component 7, and connecting valve 3, achieving power module 4 reuse and simplifying the structure of the hydrogen-oxygen generator.

[0049] In some examples, the power module 4 can supply power to the controller 6, which then converts the voltage and outputs it to the connecting valve 3, thereby supplying power to the connecting valve 3.

[0050] In some embodiments, such as Figure 4As shown, the pressure detection component 5 includes a pressure sensor 51, which is connected to the gas-liquid separator 2 and electrically connected to the controller 6.

[0051] It is understandable that the pressure sensor 51 can detect the pressure inside the gas-liquid separator 2 in real time and transmit the detection data to the controller 6, so that the controller 6 can determine the pressure inside the gas-liquid separator 2, and thus control the operation of the connecting valve 3 according to the pressure inside the gas-liquid separator 2.

[0052] In some examples, the gas-liquid separator 2 has a connection hole. The detection end of the pressure sensor 51 passes through the connection hole and is located inside the gas-liquid separator 2, allowing the pressure sensor 51 to effectively detect the internal pressure of the gas-liquid separator. The connection end of the pressure sensor 51 is located outside the internal space of the gas-liquid separator 2, meaning the connection end protrudes from the gas-liquid separator 2, facilitating electrical connection between the pressure sensor 51 and the controller 6. The pressure sensor 51 is sealed to the wall of the connection hole, improving the sealing performance at the connection between the pressure sensor 51 and the gas-liquid separator 2, preventing gas leakage from the gas-liquid separator 2 through this connection.

[0053] In some embodiments, pressure sensor 51 and controller 6 are located on the same side of gas-liquid separator 2.

[0054] It is understandable that placing the pressure sensor 51 and the controller 6 on the same side of the gas-liquid separator 2 helps to shorten the distance between the pressure sensor 51 and the controller 6, and reduces obstacles between the pressure sensor 51 and the controller 6, making the connection between the pressure sensor 51 and the controller 6 more convenient.

[0055] In some embodiments, such as Figure 1 and Figure 4 As shown, the hydrogen-oxygen generator also includes a first pipeline 9, the first end of which is connected to the outlet of the electrolytic cell 1, and the second end of which is connected to the inlet of the gas-liquid separator 2.

[0056] It is understandable that the gas generated by the electrolytic cell 1 can flow into the gas-liquid separator 2 through the first pipeline 9, thereby realizing gas transfer between the electrolytic cell 1 and the gas-liquid separator 2.

[0057] In some examples, the first pipeline 9 is provided with a unidirectional flow structure, which allows the first pipeline 9 to flow unidirectionally from the electrolytic cell 1 to the gas-liquid separator 2, thereby preventing the gas in the gas-liquid separator 2 from flowing back to the electrolytic cell 1.

[0058] In some embodiments, such as Figure 1 and Figure 4As shown, the hydrogen-oxygen generator also includes a second pipeline 10, the first end of which is connected to the outlet of the gas-liquid separator 2, and the second pipeline 10 is connected to the inlet of the connecting valve 3.

[0059] Understandably, the gas outlet of the gas-liquid separator 2 and the inlet of the connecting valve 3 are connected via the second pipeline 10, allowing the gas inside the gas-liquid separator 2 to be transported to the connecting valve 3 via the second pipeline 10, and then discharged to the outside via the connecting valve 3. The connecting valve 3 can control the gas discharge from the gas-liquid separator 2. When the connecting valve 3 is closed, the gas inside the gas-liquid separator 2 can only be transported to the inlet of the connecting valve 3 and cannot pass through the connecting valve 3. When the connecting valve 3 is open, the gas inside the gas-liquid separator 2 can be discharged sequentially through the second pipeline 10 and the connecting valve 3.

[0060] In some embodiments, such as Figure 1 and Figure 4 As shown, the hydrogen-oxygen generator also includes a third pipeline 11 and a one-way valve 12. The third pipeline 11 is connected to the outlet of the connecting valve 3, and the one-way valve 12 is connected to the third pipeline 11. The one-way valve 12 is used to make the gas in the third pipeline 11 flow unidirectionally along the direction from the connecting valve 3 to the third pipeline 11.

[0061] It is understandable that the third pipeline 11 is connected to the outlet of the connecting valve 3, meaning that the gas in the gas-liquid separator 2 can be discharged by flowing sequentially along the connecting valve 3 and the third pipeline 11. By installing a one-way valve 12 at the third pipeline 11, the one-way valve 12 allows the third pipeline 11 to be unidirectionally open in the direction from the connecting valve 3 to the third pipeline 11, allowing the gas in the gas-liquid separator 2 to be discharged through the third pipeline 11, while preventing external gas from entering the gas-liquid separator 2 through the third pipeline 11.

[0062] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
