Description

Technical Field

[0001] The present application relates to the technical field of civilian electrolyte devices, and in particular to a gas-liquid separation device and an electrolyte hydrogen production device. Background Art

[0002] In the civilian sector, hydrogen production is often done with an electrolyte. Direct current is connected to a motor and then injected into a liquid or solution, where it ionizes into a small amount of hydrogen and oxygen ions. At the cathode, the hydrogen ions receive electrons, releasing hydrogen gas. At the anode, the oxygen atoms lose electrons, releasing oxygen gas. The hydrogen generated at the cathode is collected to produce hydrogen.

[0003] However, during the hydrogen production process, some liquid mist or liquid liquid will be mixed in with the hydrogen. Since our hydrogen is relatively dry, the liquid mist or liquid liquid in the hydrogen must be separated. A common method is to directly set up a separation chamber to separate the liquid mist or liquid liquid mixed in the hydrogen, and then discharge the separated liquid liquid through a pipeline. The pipeline connection and the pipeline itself have limited pressure resistance. Therefore, under high pressure, the connection structure or pipeline will often be damaged, thus affecting the drainage effect. Summary of the Invention

[0009] Optionally, the drain valve assembly includes a closing member, a reset member and a mounting member; one end of the reset member cooperates with the closing member, and the other end cooperates with the mounting member; the mounting member is fixedly connected to the bottom of the shell, so that the closing member and the reset member are located between the mounting member and the shell, and the closing member is closed by the reset member to close the drain port.

[0010] Optionally, the drain valve assembly further includes a first flexible pad, which is provided with a avoidance hole; a drain channel is provided on at least one of the outer bottom of the shell and the surface of the mounting member facing the bottom of the shell, and the avoidance hole avoids the drain channel; the mounting member holds the first flexible pad between the mounting member and the shell.

[0011] Optionally, an inwardly protruding boss is provided at the bottom of the shell, and a mounting groove is provided in the boss; the drain port is opened on the surface of the boss and passes through the mounting groove, and the closing member is located in the mounting groove and closes the drain port.

[0012] Optionally, the gas-liquid separation device further includes a sealing gasket; the sealing gasket is held between the electrically controlled valve and the separation chamber, and the air inlet port of the electrically controlled valve is communicated with the first exhaust port or extends into the first exhaust port.

[0013] Optionally, a cooling surface is provided inside the separation chamber.

[0014] The electrolyte hydrogen production device includes: a hydrogen production component and the above-mentioned gas-liquid separation device; the gas-liquid separation device also includes a liquid storage chamber, and the separation chamber and the liquid storage chamber are respectively provided with a first air inlet and a second air inlet on the same side; the hydrogen production component includes a first air outlet and a second air outlet, and the first air outlet and the second air outlet are located on the same side; the first air inlet and the first air outlet are communicated with each other; the second air inlet and the second air outlet are communicated with each other.

[0015] Optionally, the electrolyte hydrogen production device further includes a second flexible pad, which has multiple avoidance openings, and the avoidance openings respectively avoid the first air outlet and the second air outlet; the hydrogen production component is fixedly installed at the bottom of the gas-liquid separation device, so that the second flexible pad is held between the hydrogen production component and the gas-liquid separation device.

[0016] In the embodiments of the present application,

[0017] Hydrogen generated by the electrolyte hydrogen production device enters the separation chamber through a first air inlet. Upon entering the separation chamber, the hydrogen is often mixed with liquid mist or liquid-liquid. After entering the separation chamber, the hydrogen gradually separates from the liquid mist or liquid-liquid. The liquid mist or liquid-liquid component falls to the bottom of the separation chamber due to gravity. The hydrogen is discharged to the outside through a first exhaust port, thereby achieving gas-liquid separation. An electrically controlled valve connects the first exhaust port to the outside, allowing hydrogen to continuously discharge while liquid continuously accumulates within the separation chamber. At this point, the drain valve assembly is in a first state, preventing the separation chamber from draining through the exhaust port into the drainage channel, causing the liquid to gradually accumulate and increase. When the accumulated liquid needs to be discharged, the electrically controlled valve closes the first exhaust port to the outside. Since the hydrogen production assembly continues to produce hydrogen, hydrogen continues to be generated, which accumulates within the separation chamber, causing the pressure within the separation chamber to continuously increase. This causes the drain valve assembly to enter a second state, connecting the exhaust port to the drainage channel, allowing the liquid within the separation chamber to be discharged through the exhaust port into the drainage channel. During the process of increasing the air pressure in the separation chamber, when a specific air pressure is reached, the drain valve assembly is in the second state, that is, the liquid can be squeezed out of the separation chamber by the action of air pressure. In addition, when the air pressure in the separation chamber is too high, the drain valve assembly is in the second state, which can also have a pressure-reducing effect. Moreover, in some existing practices, pipes are used for drainage; and the pipes are directly connected to the separation chamber. If the air pressure in the separation chamber is too high, the pipes will also directly bear the excessive air pressure. Long-term use can easily lead to leakage problems in the connection between the pipe and the separation chamber, or expansion and rupture problems due to the pipe being unable to withstand pressure. In this solution, after the drain valve assembly is in the second state, the drain port is connected to the drain channel, so it is only subjected to air pressure in the separation chamber, which is beneficial to improving the pressure-bearing capacity of the gas-liquid separation device. Not only that, since the use of pipes is reduced, the volume of the gas-liquid separation device can also be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application.

[0034] The embodiments of the present application provide a gas-liquid separation device and an electrolyte hydrogen production device, such as Figures 3 to 6 As shown, the gas-liquid separation device includes a separation chamber 13, a drain valve assembly 20 and an electric control valve 30; the separation chamber 13 is provided with a drain port 131, a first air inlet 132 and a first exhaust port 133, the drain valve assembly 20 is installed on the drain port 131, and a drain channel 25 is formed on the drain port 131; the electric control valve 30 is connected to the first exhaust port 133 of the separation chamber 13, and is used to control the conduction or cutoff of the separation chamber 13 with the outside; the drain valve assembly 20 includes at least a first state and a second state; the electric control valve 30 controls the conduction of the first exhaust port 133 with the outside, the drain valve assembly 20 is in the first state, and the drain channel 25 is cut off from the drain port 131; the electric control valve 30 controls the cutoff of the first exhaust port 133 with the outside, the drain valve assembly 20 is in the second state, and the drain channel 25 is conducted with the drain port 131.

[0035] The hydrogen produced by the electrolyte hydrogen production device enters the separation chamber 13 through the first air inlet 132. The newly entered hydrogen is often mixed with liquid mist or liquid liquid. After entering the separation chamber 13, the hydrogen is gradually separated from the liquid mist or liquid liquid. The liquid mist or liquid liquid component falls into the bottom of the separation chamber 13 due to gravity; and the hydrogen is discharged to the outside through the first exhaust port 133, thereby achieving gas-liquid separation. The electric control valve 30 controls the first exhaust port 133 to be connected to the outside world, hydrogen is continuously discharged to the outside, and liquid is continuously gathered in the separation chamber 13. At this time, the drain valve assembly 20 is in the first state, and the separation chamber 13 cannot drain liquid to the drain channel 25 through the drain port 131. The liquid will gradually gather and increase. When the collected liquid needs to be discharged, the electric control valve 30 controls the first exhaust port 133 to be cut off from the outside world; since the hydrogen production component 50 will continue to produce hydrogen, hydrogen is continuously produced, and the generated hydrogen is collected in the separation chamber 13, causing the air pressure in the separation chamber 13 to continue to increase; causing the drain valve component 20 to be in the second state, at this time the drain port 131 is connected to the drain channel 25, so the liquid in the separation chamber 13 is discharged to the drain channel 25 through the drain port 131. In the process of increasing air pressure in the separation chamber 13, after reaching a specific air pressure, the drain valve component 20 is in the second state, that is, the liquid can be squeezed out of the separation chamber 13 by the action of air pressure. In addition, when the air pressure in the separation chamber 13 is too high, the drain valve component 20 is in the second state, which can also have a pressure reduction effect. In some existing practices, pipes are used for drainage. These pipes are directly connected to the separation chamber 13. If the air pressure in the separation chamber 13 is too high, the pipes will also directly bear the excessive air pressure. Long-term use can easily lead to leakage between the pipes and the separation chamber 13, or the pipes cannot withstand the pressure and may expand and rupture. In this solution, after the drain valve assembly 20 is in the second state, the drain port 131 is connected to the drain channel 25. Therefore, only the separation chamber 13 is subjected to air pressure, which helps to improve the pressure-bearing capacity of the gas-liquid separation device. Furthermore, since the use of pipes is reduced, the volume of the gas-liquid separation device can also be reduced.

[0036] In this embodiment, a liquid level sensor is installed in the separation chamber 13. By sensing the liquid level height in the separation chamber, when it reaches a specific height, the liquid level sensor feeds back to the control center, and the control center controls the electric control valve 30 to be cut off, and finally completes the drainage action.

[0037] like Figure 6 as well as Figure 8 and Figure 9As shown, the gas-liquid separation device also includes a liquid storage chamber 14, which is provided with a through hole 141; when the drain valve assembly 20 is in the first state, the drain port 131 and the through hole 141 are blocked by the drain channel 25; when the drain valve assembly 20 is in the second state, the drain port 131 and the through hole 141 are connected. Specifically, the liquid storage chamber 14 is used to store liquid for hydrogen production, and the liquid separated in the separation chamber 13 can be discharged into the hydrogen production device for reuse. Here, the drain valve assembly 20 is placed in the second state by the air pressure in the separation chamber 13, thereby discharging the liquid in the separation chamber 13 and entering the liquid storage chamber 14 through the drain port 131, the drain channel 25 and the through hole 141, thereby discharging the liquid in the separation chamber 13 into the liquid storage chamber 14. The drain port 131 and the through hole 141 are connected via the drain channel 25 , avoiding the use of pipelines for communication, thereby ensuring that the gas-liquid separation device has a high pressure resistance.

[0038] like Figures 9 to 12 As shown, the gas-liquid separation device also includes a shell 10, and the separation chamber 13 and the liquid storage chamber 14 are arranged inside the shell 10, and the through hole 141 is opened at the bottom of the liquid storage chamber 14; the drain valve assembly 20 is fixedly connected to the bottom of the shell 10, and faces the drain port 131 and the liquid storage chamber 14. The separation chamber 13 and the liquid storage chamber 14 are arranged inside the shell 10 to improve the strength of the separation chamber 13 and the liquid storage chamber 14. The shell 10 of this solution itself is an integrated structure, so compared with the splicing method, the structural strength of this solution is higher. Of course, it is also feasible to make the shell 10 into separate parts, but to achieve the same strength, the manufacturing cost is relatively higher. The drain valve assembly 20 is connected to the bottom of the housing 10, and the through hole 141 is also located at the bottom of the liquid storage chamber 14, and the drain port 131 is also provided at the bottom of the separation chamber 13; therefore, the drain valve assembly 20 provided at the bottom of the housing 10 can cooperate with the drain port 131 and the through hole 141, making the coordination between the drain valve assembly 20 and the housing 10 more compact, which is conducive to reducing the volume of the gas-liquid separation device. Specifically, the drain channel 25 is formed at the bottom of the drain valve assembly 20 and the housing 10, that is, the drain channel 25 is formed by utilizing the fixed connection between the drain valve assembly 20 and the bottom of the housing 10, without the need for an additional mounting structure to form the drain channel 25. It should be noted that the drain channel 25 formed on the drain port 131 can be formed directly or indirectly; the drain channel 25 here is located outside the drain port 131, so the drain channel 25 formed on the drain port 131 is not inconsistent with the drain channel 25 described herein.

[0039] When the drain port 131 is connected to the through hole 141, if the air pressure in the separation chamber 13 is the same as the air pressure in the liquid storage chamber 14, the separation chamber 13 and the liquid storage chamber 14 will form a communicating vessel. At this time, if the liquid level in the liquid storage chamber 14 is higher than the liquid level in the separation chamber 13, the liquid in the liquid storage chamber 14 will flow into the separation chamber 13. In this embodiment, the bottoms of the separation chamber 13 and the liquid storage chamber 14 provided in the housing 10 are substantially on the same plane. Even if there is a height difference between the bottoms, the height difference does not exceed one centimeter. It can be considered that the separation chamber 13 and the liquid storage chamber 14 are flush. This arrangement can fully utilize the space in the housing 10. When the volumes of the separation chamber 13 and the liquid storage chamber 14 are the same, the volume occupied by the outer contour of the housing 10 is smaller. In actual use, the liquid level in the liquid storage chamber 14 is higher than the liquid level in the separation chamber 13; and since the air pressure in the separation chamber 13 is higher than that in the liquid storage chamber 14, when the drain valve assembly 20 is in the second state and the drain port 131 is connected to the through hole 141, the liquid in the separation chamber 13 can also be forced to enter the liquid storage chamber 14.

[0040] like Figures 7 to 9 As shown, the drain valve assembly 20 includes a closure member 21, a reset member 22, and a mounting member 23. One end of the reset member 22 cooperates with the closure member 21, and the other end cooperates with the mounting member 23. The mounting member 23 is fixedly connected to the bottom of the housing 10, so that the closure member 21 and the reset member 22 are located between the mounting member 23 and the housing 10, and the closure member 21 is acted upon by the reset member 22 to close the drain port 131. Here, the closure member 21 and the reset member 22 are mounted on the bottom of the housing 10 via the mounting member 23. Specifically, the reset member 22 is used to abut between the closure member 21 and the mounting member 23, providing power for the closure member 21 to reset. When the electric control valve 30 controls the first exhaust port 133 to be connected to the outside world, the closure member 21 is abutted against the drain port 131 by the reset member 22. When the electric control valve 30 controls the first exhaust port 133 to be cut off from the outside, the air pressure in the separation chamber 13 increases and acts on the closing member 21. The closing member 21 causes the reset member 22 to deform, and the closing member 21 leaves the drain port 131, thereby making the drain port 131 and the through hole 141 conductive. At this time, the liquid in the separation chamber 13 is discharged, and the air pressure in the separation chamber 13 also begins to decrease. The reset member 22 resumes its deformation, so that the closing member 21 is again pressed against the drain port 131, thus closing the drain port 131.

[0041] Specifically, the electric control valve 30 of this embodiment adopts a solenoid valve, and the state switching of the solenoid valve can be controlled by an electrical signal, which is conducive to switching the state control of the air pressure separation device to electrical control. In addition, the reset member 22 in this embodiment adopts a spring; when the spring is at the lowest energy storage, the closing member 21 is pressed against the drain port 131. When the pressure on the closing member 21 caused by the air pressure is greater than the pressure provided by the spring, the closing member 21 retreats, causing the spring to increase the energy storage, that is, the spring is compressed; until the pressure provided by the compressed spring is greater than the pressure provided by the air pressure, the spring releases the stored energy and then presses the closing member 21 against the drain port 131. The elastic force of the spring can be set here to control the air pressure in the separation chamber 13 to reach a specific value before the closing member 21 is pushed open. In other embodiments, the reset member 22 can also be a metal spring or a compressed gas spring.

[0042] like Figures 7 to 9 As shown, the drain valve assembly 20 further includes a first flexible pad 24, on which a avoidance hole 241 is provided; a drain channel 25 is provided on at least one of the outer bottom of the shell 10 and the surface of the mounting member 23 facing the bottom of the shell 10, and the avoidance hole 241 avoids the drain channel 25; the mounting member 23 holds the first flexible pad 24 between the mounting member 23 and the shell 10. Specifically, in this embodiment, the drain channel 25 is provided on the mounting member 23, and the mounting member 23 is attached to the bottom of the shell 10, so the drain channel 25 is located at the bottom of the shell 10. The liquid discharged from the separation chamber 13 first exits the shell 10 through the drain port 131, passes through the bottom of the shell 10, and then enters the liquid outlet chamber through the through hole 141; the flow trajectory during the drainage process is short, and the sealing requirements are relatively low. The first flexible pad 24 is positioned between the mounting member 23 and the housing 10. The mounting member 23 presses against the first flexible pad 24, deforming and sealing against the mounting member 23 and the housing 10, thereby providing a seal. The first flexible pad 24 has a clearance hole 241 positioned at the outer edge of the drainage channel 25. This allows the first flexible pad 24 to form a seal along the outer edge of the drainage channel 25 without affecting the drainage function of the drainage channel 25.

[0043] In another embodiment, the mounting member 23 does not have the drainage channel 25, but the first flexible pad 24 is further provided with an escape hole 241. In this case, the escape hole 241 forms the drainage channel 25. When the liquid in the separation chamber 13 is discharged, it is discharged into the through hole 141 through the drainage channel 25 formed by the escape hole 241.

[0044] The first flexible pad 24 is made of silicone or rubber material, and uses the flexibility of silicone and rubber to seal the gap and play a sealing role. Of course, in other embodiments, other materials can be used as long as they can seal the gap, which will not be listed here.

[0045] like Figure 8 and Figure 9 As shown, the bottom of the housing 10 is provided with an inwardly protruding boss 111, and a mounting groove 1111 is provided in the boss 111. The drain port 131 is provided on the surface of the boss 111 and extends through the mounting groove 1111. The closure member 21 is located in the mounting groove 1111 and closes the drain port 131. The reset member 22 is installed in the mounting groove 1111, which can serve as a limiter and guide. When the reset member 22 deforms, the inner wall of the mounting groove 1111 can limit the displacement of the reset member 22, thereby ensuring that the deformation of the reset member 22 is within a controllable range.

[0046] See Figure 9 As shown, the direction indicated by the dotted line and arrow is the drainage direction. The water in the separation chamber 13 first passes through the drainage port 131, then passes through the mounting groove 1111 and enters the drainage channel 25, and finally passes through the through hole 141 and is discharged into the liquid storage chamber 14.

[0047] like Figures 7 to 9 As shown, the closure member 21 includes a closed end 211 and a guide rod 212. The closed end 211 is located near the drain port 131. The guide rod 212 is located on the side of the closed end 211 facing away from the drain port 131, and the other end of the guide rod 212 is partially inserted into the guide hole 231 of the mounting member 23. The spring is mounted on the guide rod 212, so the spring expands and contracts along the axial direction of the guide rod 212. When the closed end 211 is forced away from the drain port 131, the guide rod 212 partially extends into the mounting member 23. Specifically, the guide rod 212 is configured into two sections. The diameter of the section near the closed end 211 is larger than the diameter of the section near the mounting member 23, and the diameter of the section near the closed end 211 is also larger than the diameter of the guide hole 231. When the closed end 211 is away from the liquid discharge port 131, the guide rod 212 can extend into the mounting member 23 along the guide hole 231, wherein the diameter of the section near the closed end 211 is larger than the diameter of the guide hole 231. Therefore, after the guide rod 212 extends a certain distance, it will be blocked, thereby preventing the guide rod 212 from extending too far and exceeding the elastic deformation range of the spring, thereby protecting the spring. The guide hole 231 here can pass through the mounting member 23. In this case, the diameter of the section of the guide rod 212 near the mounting member 23 is basically equal to the diameter of the mounting hole, or has a slight interference fit. This arrangement can prevent liquid from flowing out of the gap between the guide rod 212 and the guide hole 231. Because the liquid is under tension, even if there is a small gap between the section of the guide rod 212 near the mounting member 23 and the guide hole 231, it will not easily flow out.

[0048] In another embodiment, the guide hole 231 is a blind hole structure and is closed on the side of the mounting member 23 facing away from the housing 10 . In this case, there is no need to consider the outflow of liquid.

[0049] like Figures 7 to 9 As shown, a flexible pad is provided on the side of the closed end 211 close to the drain port 131. The flexible pad directly abuts against the drain port 131 and deforms under pressure to close the small gap. The flexible pad can be made of silicone, rubber, or plastic.

[0050] like Figure 11 As shown, a relief area 114 is defined at the bottom of the housing 10; the drain valve assembly 20 is mounted on the relief area 114, so that only a small portion of the drain valve assembly 20 protrudes from the bottom of the housing 10, or does not protrude at all. As a result, the bottom of the housing 10 is relatively flat, allowing the housing 10 and the drain valve assembly 20 to fit closer together, thereby reducing the size of the gas-liquid separation device.

[0051] like Figure 8 and Figure 9 As shown, the bottom of the housing 10 is provided with a plurality of inwardly protruding mounting platforms 112. These mounting platforms 112 have internally threaded holes extending inward from the outside of the bottom of the housing 10. Mounting members 23 are mounted to the bottom of the housing 10 using nails. The nails pass through the mounting members 23 and are then screwed into the internally threaded holes of the mounting platforms 112. The internally threaded holes are blind holes and do not penetrate into the separation chamber 13 and liquid storage chamber 14 within the housing 10.

[0052] like Figure 6 As shown, the gas-liquid separation device further includes a sealing gasket 40; the sealing gasket 40 is positioned between the electrically controlled valve 30 and the separation chamber 13, and the inlet port of the electrically controlled valve 30 communicates with or extends into the first exhaust port 133. When the electrically controlled valve 30 is installed, the sealing gasket 40 is compressed, thereby sealing the clearance between the electrically controlled valve 30 and the housing 10 and preventing leakage during exhaust. Furthermore, the inlet port of the electrically controlled valve 30 can be installed in two ways. One of these methods does not pass through the first exhaust port 133, but rather faces the first exhaust port 133; gas first passes through the first exhaust port 133 before entering the inlet port of the electrically controlled valve 30. In the other method, which is the installation method of this embodiment, the inlet port of the electrically controlled valve 30 extends through the first exhaust port 133 into the interior of the separation chamber 13, and the inlet port of the electrically controlled valve 30 protrudes from the inner wall of the separation chamber 13. When hydrogen enters the separation chamber 13, it readily enters the top of the separation chamber 13 due to its velocity. If exhaust were to be conducted directly from the inner wall of the top, some of the liquid mist or liquid that has not yet separated would be discharged along with the hydrogen. However, in the method of this embodiment, when the hydrogen reaches the top of the separation chamber 13, it cannot be discharged directly. The liquid mist or liquid in the hydrogen has time to separate. After further separation, the hydrogen flows downward and is discharged from the air inlet port of the electrically controlled valve 30. Therefore, the exhaust method provided in this embodiment is more conducive to gas-liquid separation.

[0053] Specifically, in this embodiment, the liquid drain port 131 and the first gas inlet 132 are both located at the bottom of the separation chamber 13, while the first gas outlet 133 is located at the top of the separation chamber 13. This arrangement allows the hydrogen gas to flow along a longer trajectory, further facilitating the separation of liquid mist or liquid from the hydrogen gas. Furthermore, the liquid drain port 131 at the bottom also facilitates the discharge of the separated liquid.

[0054] In order to enhance the gas-liquid separation effect, a cooling surface is provided inside the separation chamber 13, which facilitates the adhesion of liquid mist and liquid-liquid to the cooling surface. In other embodiments, a semiconductor refrigeration plate can also be installed, wherein the cooling side faces the separation chamber 13 and the heating side faces the liquid storage chamber 14. The hydrogen mixed with liquid mist or liquid-liquid has a lower temperature when passing through the cooling side, which is conducive to the condensation of the liquid and enhances the separation effect. In addition, since the liquid in the liquid storage chamber 14 is used for electrolytic hydrogen production, its higher temperature is more conducive to the electrolysis reaction. Therefore, the heating side of the semiconductor refrigeration plate can heat the liquid in the liquid storage chamber 14, which is conducive to accelerating the speed of the electrolysis reaction.

[0055] like Figures 4 to 6 As shown, the shell 10 includes a main body 11 and a cover body 12, and a silicone gasket or a rubber gasket is arranged between the cover body 12 and the main body 11. The cover body 12 is fixedly installed on the main body 11 by nails, and the silicone gasket is pressed against the end faces of the cover body 12 and the shell 10 to play a sealing role.

[0056] like Figure 10 As shown, an annular wall 113 is provided within the main body 11 of the housing 10. This annular wall 113 protrudes upward from the bottom of the housing 10. The interior of the annular wall 113 and the annular wall 113 and the outer wall of the main body 11 of the housing 10 enclose two spaces: the space formed within the annular wall 113 is the separation chamber 13, and the space formed between the annular wall 113 and the outer wall of the main body 11 of the housing 10 is the liquid storage chamber 14. The raised end surface of the annular wall is flush with the end of the main body 11 of the housing 10, and the cover 12 isolates the two spaces separated by the main body 11. In this case, the mating parts of the cover 12 and the main body 11 only need to be flat to isolate the two spaces separated by the main body 11, so the processing requirements for the cover 12 are relatively low. In other embodiments, the protruding height of the annular wall 113 can be set to be less than the height of the outer wall of the main body 11. In this case, the cover 12 is required to have two locations with different heights to seal the separation chamber 13 and the liquid storage chamber 14. Although the processing requirements are higher than the previous arrangement, it is also a feasible arrangement.

[0057] like Figure 10As shown, the outer end face of the main body 11 and the end face of the annular wall are both provided with protruding positioning posts 115, and corresponding positioning grooves are provided on the cover 12. When the cover 12 is placed on the main body 11, the positioning posts 115 and the positioning grooves are connected to ensure that the position between the cover 12 and the main body 11 is relatively fixed, and then the nail body is screwed in to secure it.

[0058] like Figures 1 to 3 As shown, this embodiment also provides an electrolyte hydrogen production device, including a hydrogen production component 50 and a gas-liquid separation device, wherein the separation chamber 13 and the liquid storage chamber 14 are respectively provided with a first air inlet 132 and a second air inlet 142 on the same side; the hydrogen production component 50 includes a first air outlet 51 and a second air outlet 52, and the first air outlet 51 and the second air outlet 52 are located on the same side; the first air inlet 132 and the first air outlet 51 are communicated with the second air outlet 52; the second air inlet 142 and the second air outlet 52 are communicated with each other. The first air inlet 132 and the second air inlet 142 respectively provided in the separation chamber 13 and the liquid storage chamber 14 are located on the same side and are correspondingly communicated with the first air outlet 51 and the second air outlet 52 of the hydrogen production component 50. When the hydrogen production component 50 and the housing 10 are installed, they form a whole, and there is no need to set up additional pipeline connections, thereby reducing the volume of the electrolyte hydrogen production device. During use, the liquid of the hydrogen production assembly 50 enters through the second gas outlet 52, and oxygen is also discharged through the second gas outlet 52 into the liquid storage chamber 14. The liquid storage chamber 14 is provided with a second exhaust port for discharging oxygen from the liquid storage chamber 14.

[0059] Specifically, if Figure 2 and Figure 3 As shown, the electrolyte hydrogen production device also includes a second flexible pad 60 having multiple escape openings 61 defined therein. These escape openings 61 respectively avoid the first gas outlet 51 and the second gas outlet 52. The hydrogen production assembly 50 is fixedly mounted on the bottom of the gas-liquid separation device, so that the second flexible pad 60 abuts between the hydrogen production assembly 50 and the gas-liquid separation device. There is no pipeline connection between the hydrogen production assembly 50 and the gas-liquid separation device. To ensure a good sealing effect, the second flexible pad 60 is installed between the hydrogen production assembly 50 and the gas-liquid separation device for sealing. Specifically, when the hydrogen production assembly 50 is fixedly connected to the housing 10, the second flexible pad 60 is compressed, causing it to abut against the contact surfaces of the hydrogen production assembly 50 and the gas-liquid separation device. Therefore, when the first gas outlet 51 and the first gas inlet 132 are in communication, and when the second gas outlet 52 and the second gas inlet 142 are in communication, the second flexible pad 60 prevents gas from escaping due to the sealing effect of the second flexible pad 60. The second flexible pad 60 can be made of silicone or rubber.

[0060] like Figure 1 and Figure 2As shown, the electrolyte hydrogen production device also includes an upper cover 71, a lower cover 72, and a housing 73. The hydrogen production assembly 50 and the gas-liquid separation device are both installed in the housing 73, and the upper cover 71 and the lower cover 72 are sealed at both ends of the housing 73. A hydrogen outlet hole is formed in the upper cover 71, and a movable baffle 711 is provided on the surface of the outlet hole. When hydrogen production is stopped, the baffle 711 can be moved to the outlet hole to seal it. When hydrogen production is resumed, the baffle 711 is moved out of the outlet hole to allow hydrogen to be discharged normally.

[0061] A control panel is also provided on the housing 73. The control panel can be button-type controlled or touch-type controlled. The housing 73 is cylindrical in shape and has ridges on its outer surface to increase friction for easy grip and enhance the aesthetic appeal of the lines.

[0062] It should be noted that the abutment described in this embodiment refers to the presence of extrusion and contact.

[0063] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
