[0016] The aluminum-air power supply provided by the present invention will be explained and described in detail below with reference to the accompanying drawings.

[0017] The aluminum-air power supply provided by this invention can seal the air inlet of the aluminum-air battery pack and extract the internal air through an air extraction structure, thereby isolating the air exchange between the inside and outside of the aluminum-air battery pack, cutting off the oxygen supply required by the aluminum-air battery pack in the working state, and also solving the problem of large self-corrosion in the no-load state after startup, which leads to shortened power generation time and low aluminum plate utilization. The invention will be described in detail below with reference to specific embodiments: This invention provides an aluminum-air power supply, particularly a low-power portable aluminum-air power supply for long-term operation. In some embodiments, such as... Figure 1 , Figure 2 As shown, the aluminum-air power supply of the present invention includes: an electrical component 1 and an aluminum-air battery pack 2. The electrical component 1 and the aluminum-air battery pack 2 are detachably connected, which facilitates disassembly for separate maintenance of the battery pack and the aluminum-air component.

[0018] In some embodiments, such as Figure 3 As shown, the electrical component 1 includes a housing, which includes a separate bottom shell 11 and a top cover 12. The bottom shell 11 and the top cover 12 are detachably connected. A waterproof sealing ring is provided on the mating surface of the bottom shell 11 and the top cover 12, which can effectively prevent dust, moisture and other impurities from entering the housing. It is suitable for complex usage scenarios such as outdoor and humid environments, and protects the internal circuit boards and electronic components from damage.

[0019] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a circuit board 13 is fixedly disposed inside the bottom shell 11. A positive terminal interface 14 and a negative terminal interface 15 are provided on the bottom wall of the bottom shell 11 for electrical connection with the aluminum-air battery pack 2. Optionally, the positive terminal interface 14 is a through hole formed on the bottom wall of the bottom shell 11, communicating with the internal cavity of the bottom shell 11. Figure 5 As shown, the negative terminal interface 15 is a cylinder extending outward from the bottom wall, with a through hole forming inside the cylinder that communicates with the internal cavity of the bottom shell 11. Figure 5 As shown, an output interface 16 is provided on the side wall of the bottom shell 11. The output interface 16 may include, for example, a USB interface, a Type-C interface, etc., and may also include a DC interface (such as 5V or 12V specifications) to meet the power supply needs of different electrical devices and adapt to various terminals such as mobile phones, tablets, small instruments, and emergency lighting equipment. Each output interface 16 is provided with a dustproof and waterproof cover. When not in use, the cover can be closed to further improve the protection performance. At the same time, the inside of the interface is provided with an anti-reverse insertion structure to prevent damage to the device or interface due to incorrect insertion.

[0020] Optionally, such as Figure 5 As shown, indicator lights 17 are also provided on the side wall to accurately reflect the working status of electrical components 1 and the aluminum-air power supply, replacing the simple prompts of a single indicator light 17 and improving ease of use. Indicator lights 17 may include power indicator lights, discharge indicator lights, fault indicator lights, etc. Different colored indicator lights are paired with corresponding status prompts, making it easy for users to quickly judge the operating status of the equipment and troubleshoot problems in a timely manner.

[0021] In some embodiments, the circuit board 13 integrates a power management module, a control module, and a protection module. The power management module is used to regulate the output voltage and current to ensure that the output power is stable and adaptable to different electrical devices. The control module is used to coordinate the status feedback of the indicator lights and the power supply switching of the output interface 16. The protection module includes overcurrent protection, overvoltage protection, short circuit protection, and reverse connection protection. When the device malfunctions, it can quickly cut off the circuit to prevent damage to the circuit board 13, the output device, and the aluminum-air battery pack 2, further improving the safety and reliability of the electrical components 1.

[0022] like Figure 3 , Figure 6 A liquid inlet 18 is provided on the upper part of the bottom shell 11. The liquid inlet 18 forms a through hole on the bottom wall of the bottom shell 11, and a guide tube is formed inside the bottom shell 11 that communicates with the through hole. The guide tube extends to the outside of the bottom shell 11, separating the liquid inlet 18 from the internal space of the bottom shell 11. This completely avoids leakage and splashing when adding electrolyte, prevents electrolyte from contacting electronic components such as the circuit board 13 and terminals inside the bottom shell 11, effectively avoids the risk of corrosion damage, and ensures the operational stability of the electrical components 1. A sealing cap 19 is also provided at the end of the guide tube for removable sealing of the guide tube, thereby achieving sealing protection of the liquid inlet 18, preventing electrolyte evaporation and leakage, and blocking dust, moisture and other impurities from entering the interior of the guide tube.

[0023] The top cover 12 is fitted onto the bottom shell 11 and makes sealing contact with the bottom shell 11. For example, it can be connected by screws or other connectors, and a sealing ring is provided at the contact position for sealing. An avoidance hole is formed on the top cover 12 at the position corresponding to the liquid inlet 18. The guide tube extends through the avoidance hole. Optionally, a sealing ring is provided between the avoidance hole and the guide tube for sealing.

[0024] Optionally, such as Figure 1 , Figure 5 As shown, a handle 121 is provided on the top cover 12. For example, handles 121 are symmetrically provided at both ends of the top cover 12 to improve the overall portability of the aluminum air power supply and facilitate users to move and transport the equipment. The handle 121 is made of high-strength engineering plastic in one piece or is fastened to the top cover 12 by bolts to ensure a firm connection, which can withstand the overall weight of the power supply and prevent breakage or loosening during transportation.

[0025] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the aluminum-air battery pack 2 includes two cells 21, which are arranged opposite each other and connected as a whole. The contact points of the two cells 21 form a sealed contact, and a closed cavity 201 is formed between the two cells 21. For example, an annular sealing groove is provided on the mating surface, and an electrolyte-resistant and aging-resistant fluororubber sealing gasket is embedded in the groove, completely covering the gap of the mating surface. Optionally, a positioning structure is provided on the contact surface of the two cells 21, such as a positioning post cooperating with a positioning hole, to ensure that the two cells 21 are accurately mated and the force is evenly distributed, avoiding misalignment that could lead to sealing failure.

[0026] like Figure 8As shown, each monomer 21 has vents 211 at both ends, which communicate with the enclosed cavity 201 to facilitate gas exchange between the enclosed cavity 201 and the outside environment. This allows for the timely removal of gases generated during the electrochemical reaction and the introduction of air to provide oxygen for the reaction, ensuring its continuous and stable progress. Optionally, the vents 211 are formed at both ends of the monomer 21, with multiple vents distributed vertically along the edges. The vents 211 at both ends of two monomers 21 are symmetrically arranged to ensure uniform gas exchange and prevent local gas accumulation from affecting reaction efficiency. In this embodiment, the two sides of the monomer 21 extend along the edges to form a connecting groove 212, and the vents 211 are formed on the bottom wall of the connecting groove 212.

[0027] like Figure 8 , Figure 9 As shown, the aluminum-air battery pack 2 also includes a first outer shell 22 and a second outer shell 23. The first outer shell 22 and the second outer shell 23 are respectively fastened to the outside of the two cells 21 and are fixedly connected to the cells 21 by a detachable connection structure to form an integral unit, which facilitates the disassembly, cleaning and maintenance of the outer shell, and at the same time protects the cells 21.

[0028] like Figure 8 As shown, airflow channels 202 are formed between the first outer shell 22 and the second outer shell 23 and the monomer 21, providing a sufficient and smooth air supply for the aluminum-air battery reaction and ensuring the continuous and stable electrochemical reaction. Optionally, a gap is formed between the first outer shell 22 and the second outer shell 23 and the outer wall of the monomer 21, which constitutes the airflow channel 202. The airflow channel 202 is connected to the closed cavity 201 between the two monomers 21 through the vent 211. Both the first outer shell 22 and the second outer shell 23 have openable and closable air inlets, through which the air required for the reaction of the two monomers 21 enters. The airflow channel 202 is connected to the closed cavity 201 between the two monomers 21 through the vent 211 at both ends of the monomer 21, forming a complete gas flow path of "air inlet - airflow channel 202 - vent 211 - closed cavity 201", realizing the orderly input of air and the smooth discharge of reaction gases.

[0029] In some embodiments, such as Figure 10 , Figure 11As shown, the openable and closable air inlet includes a first air inlet 221 formed on the first housing 22 and a second air inlet 231 formed on the second housing 23. For example, both the first air inlet 221 and the second air inlet 231 include multiple square or circular openings arranged in an array. The array arrangement can increase the air intake area and increase the air intake volume, while preventing the area of ​​a single opening from being too large. This ensures that the first housing 22 and the second housing 23 have strong structural strength. The dispersed small openings can effectively distribute the stress on the housing, ensuring that the first housing 22 and the second housing 23 have strong structural rigidity and are not easily deformed or damaged. At the same time, the small opening design also facilitates the sealing of the air inlet, adapting to the functional requirements of the openable and closable design. Optionally, the first air inlet 221 and the second air inlet 231 are symmetrically arranged to ensure that the air intake volume of the two cells 21 is uniform and consistent, avoiding differences in the reaction efficiency of the two cells 21 due to uneven air intake, which would affect the overall performance of the battery pack.

[0030] like Figure 1 , Figure 2 , Figure 8 The first outer shell 22 is provided with a first sealing curtain 241, which is used to seal the first air inlet 221. The second outer shell 23 is provided with a second sealing curtain 242, which is used to seal the second air inlet 231. Optionally, the first sealing curtain 241 and the second sealing curtain 242 are made of silicone rubber sheet or other flexible sheet, or other flexible polymer material. The flexible material has good deformation ability and fit, which makes it easy for users to lift or lower it to realize the quick opening and closing of the air inlet. When it is lowered to seal, it can also deform itself to fit tightly to the surface of the first outer shell 22 and the second outer shell 23 and the edge of the air inlet, fill the tiny gaps, and ensure the sealing reliability when sealing. Optionally, the first sealing curtain 241 is detachably connected to the first housing 22 via Velcro, and the second sealing curtain 242 is detachably connected to the second housing 23 via Velcro. The Velcro connection method is convenient and flexible, facilitating both daily opening and closing of the sealing curtains and individual removal and replacement when the curtains show wear or aging, without disassembling the entire housing, significantly improving maintenance convenience. For example, Velcro can be provided on the edges of the first and second sealing curtains 241 and 242, or only on the upper and lower edges. When the first and second sealing curtains 241 and 242 are lifted, the first air inlet 221 and the second air inlet 231 can be used for gas exchange between the fuel cell stack and the outside during power generation, meeting the needs for oxygen supply and heat dissipation. When the first and second sealing curtains 241 and 242 are lowered, they are connected to the first and second housings via Velcro, sealing the first air inlet 221 and the second air inlet 231, preventing gas exchange between the inside and outside of the fuel cell stack.

[0031] like Figure 7 , Figure 8 , Figure 9 As shown, an air extraction structure is provided on the first outer shell 22 or the second outer shell 23. The air extraction structure is used to extract air from the airflow channel 202 when the openable and closable air inlet is closed. In this embodiment, the air extraction structure is provided on the first outer shell 22. The air extraction structure includes an airbag 25. The airbag 25 is made of a flexible rubber material that is resistant to aging and has excellent sealing performance. It has good elasticity and deformation recovery ability, can be repeatedly pressed and used without being easily damaged. At the same time, its inner wall is treated with anti-corrosion to resist the erosion of electrolyte vapor and extend its service life.

[0032] like Figure 8 As shown, the airbag 25 is equipped with a one-way air intake valve 251 and a one-way air exhaust valve 252. The two valves work together to achieve one-way airflow, ensuring that the air extraction process is efficient and orderly: the one-way air intake valve 251 only allows airflow from the airflow channel 202 into the airbag 25, preventing air from flowing back into the airflow channel 202; the one-way air exhaust valve 252 only allows air from the airbag 25 to be discharged to the external space, preventing external air from entering the airbag 25 or the airflow channel 202 through the exhaust valve, thus ensuring the air extraction effect.

[0033] like Figure 8 As shown, a mounting platform 222 is provided on the first outer shell 22. A hole communicating with the airflow channel 202 is formed within the mounting platform 222. The airbag 25 is mounted on the mounting platform 222. A one-way air intake valve 251 communicates with the airflow channel 202, and an exhaust one-way valve communicates with the external space. When the airbag 25 is compressed, the internal air is discharged to the outside through the one-way exhaust valve 252. When the airbag 25 returns to its original shape, the air in the airflow channel 202 can enter the airbag 25 through the one-way air intake valve 251. With the first air intake 221 and the second air intake 231 closed, repeatedly pressing the airbag 25 can expel air, creating a near-vacuum state in the closed cavity 201 between the two cells 21. This stops the reaction of the fuel cell stack and solves the problem of severe self-corrosion of aluminum-air batteries under no-load power generation conditions.

[0034] The working process of the air extraction structure is precisely coordinated with the closing state of the sealing curtain. The specific working principle is as follows: When the aluminum-air battery pack 2 is in an unloaded or non-working state, the user first lowers the first sealing curtain 241 and the second sealing curtain 242, which are tightly sealed to the corresponding outer shells through Velcro, completely sealing the first air inlet 221 and the second air inlet 231, blocking outside air from entering the airflow channel 202; at this time, the user can perform the air extraction operation by repeatedly pressing the airbag 25—when the airbag 25 is squeezed, its internal volume decreases, the pressure increases, and the internal air will pass through the single... The air is quickly discharged to the external space through the exhaust valve 252. When the airbag 25 is released, the airbag 25 returns to its original shape under its own elasticity, and a negative pressure is formed inside. At this time, the air in the airflow channel 202 will enter the airbag 25 through the through hole of the mounting platform 222 and the one-way air intake valve 251 under the negative pressure. By repeatedly pressing the airbag 25, the air in the airflow channel 202 can be gradually extracted, and then the air in the closed cavity 201 between the two units 21 can be extracted through the vent 211, so that the closed cavity 201 is in a near-vacuum state.

[0035] The design of this venting structure fundamentally solves the problem of severe self-corrosion in aluminum-air batteries under no-load power generation conditions: With the sealed cavity 201 in a near-vacuum state, the oxygen required for the electrochemical reaction is completely blocked, thus stopping the electrochemical reaction in the aluminum-air battery. This avoids the ineffective consumption of the aluminum anode under no-load conditions, reduces self-corrosion losses, extends the service life of the aluminum-air battery pack 2, and lowers operating costs. Simultaneously, the venting structure employs a manual airbag 25 design, requiring no additional power source, making it easy to operate and suitable for outdoor scenarios without power. The airbag 25 is compact, occupying minimal space when installed on the first outer shell 22, and does not affect the overall portability and structural integrity of the battery pack.

[0036] In some embodiments, such as Figure 7 As shown, each of the two individual units 21 is provided with a conductive connector 213, which is used for electrical connection of the electrical component 1. Optionally, the conductive connector 213 has a cylindrical structure and is provided corresponding to the positive terminal interface 14 on the electrical component 1. Each conductive connector 213 on each individual unit 21 corresponds to one positive terminal interface 14. The conductive connector 213 extends into the bottom shell 11 through the positive terminal interface 14 and is electrically connected to the circuit board 13.

[0037] In some embodiments, such as Figure 7As shown, a latch 26 is provided on the cell 21, and a hook 111 is provided on the housing. The electrical component 1 and the aluminum-air battery pack 2 are detachably connected via the latch 26 and the hook 111. The detachable connection via the latch 26 requires no tools, improving assembly and disassembly efficiency and accommodating frequent anode replacements in aluminum-air batteries. A sealing gasket is provided around the mating end face of the electrical component 1 and the aluminum-air battery pack 2. When the latch 26 engages and locks with the hook 111, it simultaneously applies axial pressure to the sealing gasket, forming an annular sealed cavity to prevent alkaline electrolyte vapor and moisture from entering the interior of the electrical component 1. For example, the latch 26 can be provided on one of the cells 21, or it can be provided at the connection point of two cells 21 and connected to both cells 21 simultaneously. The hook 111 is provided on the side wall of the bottom shell 11. The latch 26 and the hook 111 are detachably connected and can press the electrical component 1 onto the aluminum-air battery pack 2.

[0038] To ensure the balance of the connection and the reliability of the locking, one latch 26 is provided on each side of the aluminum-air battery pack 2. The two latches 26 are symmetrically arranged and are detachably connected to two corresponding locking hooks 111 on the side wall of the bottom shell 11. When locking, the two latches 26 exert force simultaneously to press the electrical component 1 smoothly onto the aluminum-air battery pack 2, so that the sealing gaskets on the mating end faces are subjected to uniform force, avoiding local sealing failure. The latches 26 are made of high-strength engineering plastic material with anti-corrosion treatment to resist the erosion of electrolyte vapor and extend service life. The latches 26 are designed with a press-type structure, which can be unlocked by pressing, making operation convenient and further improving the efficiency of assembly and disassembly.
