Description

Technical Field

[0001] This utility model relates to the field of sealing technology for alkaline batteries, and in particular to a dual-mode humidity-controlled alkaline battery sealing structure. Background Technology

[0002] Alkaline batteries are widely used in household appliances, medical equipment, and other fields due to their high energy density and low cost. However, during long-term storage, fluctuations in ambient humidity can cause electrolyte evaporation or moisture absorption, thereby accelerating the battery's self-discharge. Statistics show that traditional alkaline batteries experience an average annual capacity loss of about 5% during storage, which seriously affects the battery's lifespan and reliability. In recent years, with the increasing demands on battery performance from electronic devices, improving the long-term storage stability of alkaline batteries has become a research hotspot in the industry.

[0003] Currently, the industry mainly addresses the humidity and sealing issues of alkaline batteries through the following methods: using single-material sealing rings (such as rubber or silicone) to prevent electrolyte leakage, but these materials cannot regulate internal humidity, and electrolyte evaporation or moisture absorption will still occur after long-term storage; adding desiccants (such as silica gel particles) inside the battery, but the moisture absorption capacity of desiccants is limited and cannot dynamically regulate humidity, leading to a decline in battery performance under extreme humidity conditions.

[0004] Current alkaline battery sealing structures cannot dynamically regulate the internal humidity of the battery, and it is difficult to balance the air permeability and leakage prevention performance of the sealing structure. In addition, traditional desiccants or corrosion inhibitors cannot maintain a stable humidity environment for a long time, resulting in a high self-discharge rate of the battery under extreme humidity conditions. At the same time, there is a lack of an active compression structure to ensure the effective sealing of the gasket. Therefore, a dual-mode humidity-controlled alkaline battery sealing structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dual-mode humidity-controlled alkaline battery sealing structure, which aims to improve the problems of existing sealing structures being unable to dynamically regulate internal humidity, electrolyte evaporation or moisture absorption during long-term storage, limited long-term effects of traditional corrosion inhibitors and desiccants, and lack of necessary sealing gasket pressure structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dual-mode humidity-controlled alkaline battery sealing structure includes a steel shell, a sealing block slidably connected inside the steel shell, a disassembly and assembly mechanism provided on the outside of the steel shell, a sealing mechanism provided inside the sealing block, a current collecting needle fixedly connected to the bottom end of the sealing block, and a separation tube fixedly connected inside the steel shell.

[0008] The sealing mechanism includes a rotating screw, the external thread of which is connected to the inside of the sealing block. A rotating ring is rotatably connected to the bottom end of the rotating screw, and a pressing plate is rotatably connected to the outside of the rotating ring. A sealing gasket is provided at the bottom end of the sealing block, and a reinforcing component is provided inside the sealing gasket.

[0009] The above technical solution constructs a sealed structure for alkaline batteries with multiple components working together. The steel shell, sealing block, disassembly and assembly mechanism, sealing mechanism, current collector needle and separation tube cooperate with each other to lay the foundation for efficient sealing, convenient disassembly and assembly, and stable electrochemical reaction of the battery, thus ensuring the overall performance and use effect of the battery.

[0010] As a further description of the above technical solution:

[0011] The outside of the extrusion plate is slidably connected to the inside of the sealing block, and the outside of the sealing gasket is in contact with the outside of the separation tube;

[0012] Through the above technical solution: the extrusion plate slides inside the sealing block, which can apply uniform extrusion force to the sealing gasket under the action of the sealing mechanism. The sealing gasket is in contact with the outside of the separation tube, which ensures the effective isolation of the separation tube from the outside world, avoids direct contact between zinc paste and other substances and the external environment, enhances the sealing and stability of the internal structure of the battery, and helps to maintain the normal electrochemical reaction environment inside the battery.

[0013] As a further description of the above technical solution:

[0014] The outer side of the sealing gasket is in contact with the inner wall of the steel shell, and zinc paste is provided inside the separation tube;

[0015] Through the above technical solution, the sealing gasket is in close contact with the inner wall of the steel shell, forming a double sealing defense, which further improves the overall sealing performance of the battery and effectively prevents electrolyte leakage and external impurities from entering the battery. At the same time, zinc paste is placed inside the separator tube, allowing the zinc paste to participate in the electrochemical reaction in a stable space, thereby improving the safety and reliability of the battery.

[0016] As a further description of the above technical solution:

[0017] The reinforcing component includes a leak-proof layer, which is externally fixedly connected to the inside of the sealing gasket. An air-permeable layer is fixedly connected to the inside of the sealing gasket, and a moisture-absorbing layer is fixedly connected to the inside of the sealing gasket.

[0018] Through the above technical solution, the leak-proof layer, the breathable layer and the moisture-absorbing layer in the enhanced component work together. The leak-proof layer can prevent electrolyte leakage, the breathable layer can balance the gas exchange inside and outside the battery, and the moisture-absorbing layer can regulate the internal humidity of the battery. These three layers work together to comprehensively improve the performance of the sealing gasket, ensure that the battery can operate stably in different humidity environments, and extend the battery's service life.

[0019] As a further description of the above technical solution:

[0020] The top end of the breathable layer is fixedly connected to the bottom end of the leak-proof layer, and the top end of the moisture-absorbing layer is fixedly connected to the bottom end of the breathable layer.

[0021] The above technical solution, with its layered arrangement of a breathable layer and a moisture-absorbing layer, makes the regulation of gas and humidity more orderly. The breathable layer allows water vapor to pass through while blocking impurities, and transfers the treated gas to the moisture-absorbing layer. The moisture-absorbing layer absorbs or releases moisture according to changes in ambient humidity, precisely regulating the internal humidity of the battery and providing suitable humidity conditions for the chemical reactions inside the battery.

[0022] As a further description of the above technical solution:

[0023] The disassembly and assembly mechanism includes a fixed column, which is externally fixedly connected to the inside of the steel shell. A rotating rod is rotatably connected to the outside of the fixed column. A threaded column is internally threaded to the rotating rod. A rotating block is fixedly connected to the front end of the rotating rod, and a limiting block is fixedly connected to the top end of the rotating rod.

[0024] Through the above technical solution, the fixed column, rotating rod, threaded column, rotating block and limiting block in the disassembly and assembly mechanism cooperate to form a convenient battery disassembly and assembly procedure. The fixed column provides support and a rotation base for the rotating rod. The rotation of the rotating rod drives the threaded column to move. The rotating block is easy to operate. The limiting block is used to position and fix the sealing block, realizing the rapid assembly and disassembly of the battery, which facilitates the production, maintenance and repair of the battery.

[0025] As a further description of the above technical solution:

[0026] The external thread of the threaded column is connected to the inside of the sealing block, and the bottom end of the limiting block contacts the top end of the sealing block;

[0027] Through the above technical solution—the threaded connection between the threaded post and the sealing block, and the contact fit between the limiting block and the top of the sealing block—the position of the sealing block can be reliably fixed during battery assembly, ensuring the stability of the battery structure. When disassembly is required, the restriction on the sealing block can be easily released by operating the threaded post to remove it. The operation is simple and efficient, improving the maintainability of the battery.

[0028] As a further description of the above technical solution:

[0029] The rotating rod is externally slidably connected to the inside of the steel shell, and the current collecting needle is externally fixedly connected to the inside of the zinc paste.

[0030] Through the above technical solution: the rotating rod is slidably connected inside the steel shell, which ensures the smooth movement of the rotating rod and also enhances the structural stability between the disassembly and assembly mechanism and the steel shell. The current collecting needle is fixedly connected to the zinc paste, which can effectively collect the current generated by the zinc paste during the electrochemical reaction, realize the smooth output of electrical energy inside the battery, and ensure the stability of the battery powering external devices.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, after the battery is assembled, rotating the rotating screw drives the rotating ring, which in turn drives the extrusion plate to squeeze the sealing gasket. Under the extrusion action, the sealing gasket tightly wraps the relevant components and makes close contact with the steel shell, effectively preventing the zinc paste from contacting the manganese ring and ensuring the normal progress of the internal chemical reaction of the battery. At the same time, the leak-proof layer inside the sealing gasket is made of silicone to prevent electrolyte leakage and provide basic physical sealing for the battery. The breathable layer uses a polytetrafluoroethylene microporous membrane, which allows water vapor to pass through and blocks liquids and impurities, balancing the gas exchange inside and outside the battery. The zeolite molecular sieve in the inner layer, with a moisture absorption capacity of ≥20% of the leak-proof layer, adsorbs or releases moisture according to changes in ambient humidity, dynamically regulating the internal humidity of the battery. Through the synergistic effect of this series of structures and materials, the sealing performance of the battery is effectively improved, ensuring that the battery can operate stably in different humidity environments and extending the battery's service life.

[0033] 2. In this utility model, the sealing gasket is placed on the bottom of the sealing block, and then the sealing block is slid into the steel shell. Subsequently, the rotating rod connected to the fixed column is rotated so that the bottom of the limiting block contacts the top of the sealing block. Finally, the rotating block is rotated so that the limiting block enters the interior of the sealing block, thus completing the battery assembly. During disassembly, the rotating block is rotated in the opposite direction so that the threaded column rotates out of the sealing block, thus removing the restriction on the sealing block and completing the disassembly. This convenient disassembly and assembly process greatly improves the efficiency of battery assembly and maintenance, reduces the difficulty of operation, and allows staff to quickly complete the installation and disassembly of batteries, thereby improving the convenience of battery production and maintenance.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figure 2 , Figure 4 and Figure 5 The present invention provides an embodiment of a dual-mode humidity-controlled alkaline battery sealing structure, comprising a steel shell 1, a sealing block 2 slidably connected inside the steel shell 1, a disassembly and assembly mechanism 3 provided outside the steel shell 1, the presence of the disassembly and assembly mechanism 3 greatly improves the convenience of battery assembly and maintenance, a sealing mechanism 7 provided inside the sealing block 2, the sealing mechanism 7 is used to ensure the sealing effect of the battery, a current collecting needle 6 is fixedly connected to the bottom end of the sealing block 2, and a separation tube 4 is fixedly connected inside the steel shell 1;

[0043] Specifically, through the coordinated work of components such as the steel shell 1, sealing block 2, disassembly and assembly mechanism 3, sealing mechanism 7, current collector 6, and separation tube 4, efficient battery sealing, convenient assembly and maintenance, stable power output, and optimization of the battery's internal structure are achieved. The disassembly and assembly mechanism 3 simplifies the battery assembly and maintenance process, the sealing mechanism 7 effectively ensures battery sealing and prevents interference from internal components and the entry of external impurities, the current collector 6 ensures smooth power output, and the separation tube 4 optimizes the internal layout. The combined effect of these components improves the overall performance and lifespan of the battery.

[0044] The sealing mechanism 7 is a key component for ensuring the stability of the internal environment and battery performance. The sealing mechanism 7 includes a rotating screw 71, whose external threads are connected to the inside of the sealing block 2. This threaded connection allows the rotating screw 71 to move up and down along the internal threads of the sealing block 2 during rotation. A rotating ring 72 is rotatably connected to the bottom end of the rotating screw 71. The rotating ring 72 can rotate in a circular motion as the rotating screw 71 rotates, and can also move up and down under the influence of the rotating screw 71. A pressing plate 73 is rotatably connected to the outside of the rotating ring 72. When the rotating ring 72 moves up and down, it causes the pressing plate 73 to slide inside the sealing block 2. A sealing gasket 74 is provided at the bottom end of the sealing block 2. The sealing gasket 74 comes into contact with the steel shell 1 and the separation tube 4, serving a sealing and isolation function. After the battery is assembled, the rotating screw 71 can be rotated, which drives the rotating ring 72. The rotating ring 72 then drives the extrusion plate 73 to extrude the sealing gasket 74. During the extrusion process, the sealing gasket 74 will deform to a certain extent, thus more precisely wrapping the relevant components and making close contact with the steel shell 1. In this way, not only is the contact between the zinc paste 5 and the manganese ring effectively avoided, preventing mutual interference between different electrode materials and ensuring the normal progress of the electrochemical reaction inside the battery, but the sealing effect of the steel shell 1 is also greatly enhanced, preventing external moisture, impurities, etc. from entering the battery and affecting the battery's performance and service life.

[0045] Specifically, in the sealing mechanism 7, the rotating screw 71 is threadedly connected to the sealing block 2 and can move up and down when rotated, driving the rotating ring 72 to make circumferential motion and vertical displacement. The rotating ring 72 then drives the extrusion plate 73 to slide inside the sealing block 2. After the battery is assembled, rotating the rotating screw 71 causes the extrusion plate 73 to extrude the sealing gasket 74, causing it to deform and tightly wrap around the relevant components and fit against the steel shell 1, preventing the zinc paste 5 from contacting the manganese ring and enhancing the sealing effect of the steel shell 1.

[0046] The sealing gasket 74 contains a reinforcing component 75, which further enhances its performance. The reinforcing component 75 includes a leak-proof layer 751 made of silicone, which is tightly fixed inside the sealing gasket 74. The main function of the leak-proof layer 751 is to isolate the battery from the external environment, preventing electrolyte leakage and providing basic physical sealing protection. During battery use, the leak-proof layer 751 effectively prevents electrolyte from seeping out of the battery, avoiding corrosion and pollution of the surrounding environment. It also protects other internal components from electrolyte leakage, ensuring battery stability and safety. The battery is also fixedly connected to a breathable layer 752, which is made of polytetrafluoroethylene microporous membrane. The breathable layer 752 selectively allows water vapor to pass through while blocking liquids and impurities from entering the battery, thus balancing the exchange of gases inside and outside. When the battery is working, a certain amount of heat and gas will be generated inside. The breathable layer 752 allows water vapor and other gases to be slowly discharged under certain conditions, while preventing external liquids and dust and other impurities from entering the battery, maintaining the relative stability of the internal environment of the battery and ensuring the normal operation of the battery. The top of the moisture-absorbing layer 753 is fixedly connected to the bottom of the breathable layer 752. The moisture-absorbing layer 753 is made of zeolite molecular sieve and has a moisture absorption capacity of ≥20%. The moisture-absorbing layer 753 dynamically regulates the internal humidity of the battery by adsorbing and releasing moisture. When the ambient humidity is high, the moisture-absorbing layer 753 will actively adsorb excess moisture to prevent the battery from accelerating self-discharge due to excessive humidity. When the ambient humidity is low, the moisture-absorbing layer 753 will release the stored moisture to avoid excessive evaporation of the electrolyte, thereby maintaining the internal humidity of the battery within a suitable range (40 to 55%RH), extending the battery's lifespan, and improving the battery's performance stability. The inner wall of the positive electrode ring is coated with a cerium oxide nanoparticle layer (particle size 50nm) to catalyze the decomposition of trace amounts of H2 / O2 generated, preventing the accumulation of internal gas pressure.

[0047] Specifically, inside the sealing gasket 74, the leak-proof layer 751 is tightly fixed therein, and is made of silicone material to isolate the external environment and prevent electrolyte leakage; the breathable layer 752 is fixed below the leak-proof layer 751, and uses the characteristics of polytetrafluoroethylene microporous membrane to balance the gas exchange inside and outside the battery; the moisture-absorbing layer 753 is fixed below the breathable layer 752, and with the moisture absorption capacity of zeolite molecular sieve ≥20%, it adsorbs or releases moisture according to the ambient humidity, maintaining the internal humidity of the battery at 40 to 55%RH.

[0048] A current collector 6 is fixedly connected to the bottom of the sealing block 2. The current collector 6 is externally fixedly connected to the inside of the zinc paste 5. The current collector 6 plays an important role in collecting and conducting current during the electrochemical reaction process of the battery, ensuring that the electrical energy generated by the battery can be output smoothly and providing stable power support for external devices. A separation tube 4 is fixedly connected inside the steel shell 1. The separation tube 4 effectively separates different areas inside the battery, ensuring that components such as the zinc paste 5 exist stably in their respective spaces, avoiding mutual interference. It also helps to optimize the internal structural layout of the battery and improve the overall performance of the battery.

[0049] Specifically, the current collecting needle 6 is fixed to the bottom of the sealing block 2, and the outside of the current collecting needle 6 is fixedly connected to the zinc paste 5 so that it can collect and conduct current in the battery electrochemical reaction. The separation tube 4 is fixed inside the steel shell 1 to separate different areas inside the battery, so that components such as zinc paste 5 can exist stably in their respective spaces, thus optimizing the internal structural layout of the battery.

[0050] Reference Figure 1 , Figure 2 and Figure 3 The disassembly / assembly mechanism 3 includes a fixed column 31, which is firmly fixed inside the steel shell 1, providing a stable support point for the entire disassembly / assembly mechanism 3. A rotating rod 32 is rotatably connected to the outside of the fixed column 31, allowing the rotating rod 32 to rotate flexibly around the fixed column 31. This design enables the rotating rod 32 to adjust its position and angle at different operating stages. A threaded post 35 is threadedly connected inside the rotating rod 32, and the threaded post 35 engages with the rotating rod 32, allowing the rotating rod 32 to drive the threaded post 35 to make corresponding displacements when rotating. A rotating block 34 is fixedly connected to the front end of the rotating rod 32, providing a convenient point of force application for the operator. By rotating the rotating block 34, the operator can easily drive the rotating rod 32 and the threaded post 35 to move. The top end of the rotating rod 32 is fixed... A limiting block 33 is connected, which plays an important role in positioning and fixing during battery assembly and disassembly. When assembling the battery, the workers first inject the manganese ring, the separator tube 4 and the zinc paste 5 into the steel shell 1 in sequence. Then, the sealing gasket 74 is placed on the bottom end of the sealing block 2. Next, the bottom end of the sealing block 2 is slid into the interior of the steel shell 1. Then, the rotating rod 32 is rotated outside the fixed post 31, so that the bottom end of the limiting block 33 contacts the top end of the sealing block 2. At this time, the limiting block 33 plays a role in initially positioning the sealing block 2. Subsequently, the rotating block 34 is rotated. Due to the threaded connection between the threaded post 35 and the rotating rod 32, the rotation of the rotating block 34 will cause the threaded post 35 to gradually enter the interior of the sealing block 2, thereby firmly fixing the position of the sealing block 2 and completing the battery assembly.

[0051] Specifically, a fixing post 31 is fixed inside the steel shell 1, and a rotating rod 32 is rotatably connected to the outside of the fixing post 31. A threaded post 35 is threadedly connected inside the rotating rod 32. A rotating block 34 is fixed at the front end of the rotating rod 32, and a limiting block 33 is fixed at the top end. When assembling the battery, the manganese ring, the separator tube 4, and the zinc paste 5 are first placed into the steel shell 1. The sealing gasket 74 is placed on the bottom end of the sealing block 2 and then slid into the steel shell 1. The rotating rod 32 is rotated so that the limiting block 33 contacts and positions itself with the top end of the sealing block 2. Then the rotating block 34 is rotated so that the threaded post 35 enters the sealing block 2 and fixes its position.

[0052] Working principle: When the operator needs to disassemble or assemble the battery, firstly, the manganese ring, the separator tube 4, and the zinc paste 5 are injected into the interior of the steel shell 1 in sequence. Then, the sealing gasket 74 is placed on the bottom end of the sealing block 2, and the bottom end of the sealing block 2 is slid into the interior of the steel shell 1. Then, the rotating rod 32 is rotated outside the fixed post 31, so that the bottom end of the limiting block 33 contacts the top end of the sealing block 2. Then, the rotating block 34 is rotated, so that the outside of the limiting block 33 enters the interior of the sealing block 2, thereby fixing the position of the sealing block 2 and completing the battery assembly. When disassembly is required, the rotating block 34 is rotated in the opposite direction, so that the threaded post 35 rotates out from the interior of the sealing block 2, thereby removing the restriction on the position of the sealing block 2. At this time, the battery disassembly is completed. Through the convenient disassembly and assembly structure, the battery can be quickly disassembled and assembled, which is convenient for assembly and maintenance.

[0053] After the battery is assembled, rotating the rotating screw 71 causes the rotating ring 72 to drive the extrusion plate 73 to extrude the sealing gasket 74, thereby ensuring that the sealing gasket 74 precisely wraps around the steel shell 1 and makes tight contact with it. This prevents the zinc paste 5 from contacting the manganese ring and ensures the sealing effect of the steel shell 1. Meanwhile, the leak-proof layer 751 is made of silicone, and its main function is to isolate the external environment and prevent electrolyte leakage, providing basic physical sealing protection for the battery. The breathable layer 752 is made of polytetrafluoroethylene microporous membrane, which selectively allows water vapor to pass through while blocking liquids and impurities from entering the battery, balancing the exchange of gases inside and outside. The inner layer is made of zeolite molecular sieve, which has a moisture absorption capacity of ≥20%, and dynamically regulates the internal humidity of the battery by adsorbing and releasing moisture.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
