Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric pressure cooker technology, specifically to an electric pressure cooker with a safety locking lid protection device. Background Technology
[0002] Currently, electric pressure cookers are a common appliance in modern kitchens, and their safety and ease of use are core concerns for users. Traditional electric pressure cookers often feature an embedded or handleless inner pot design. Users must directly contact the high-temperature area inside the pot or use tools to remove or place the inner pot, making the process cumbersome and posing a risk of burns. Even in products with inner pot handles, their placement often leads to uneven force application, causing the inner pot to slip or food to spill, severely impacting the user experience and safety.
[0003] Regarding anti-scalding design, existing products often only insulate the surface of the pot, neglecting high-temperature protection for critical components such as the inner pot handle. When users move the electric pressure cooker, they are very likely to accidentally touch the hot inner pot handle, leading to burns, especially when the pot is still hot after cooking, making the safety hazard even more prominent. In addition, most electric pressure cookers rely on a single pressure relief valve for their pressure relief system, which cannot accurately respond to pressure changes, posing a risk of pressure runaway and failing to meet users' higher requirements for cooking stability and safety.
[0004] In summary, existing electric pressure cookers suffer from structural design flaws such as inconvenient inner pot placement, insufficient anti-scalding measures, and crude pressure control. There is an urgent need for an innovative solution that balances convenient operation, efficient protection, and precise pressure control to address the shortcomings of existing technologies and improve the overall performance and user experience of the product. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an electric pressure cooker with a safety locking lid protection device, which solves the problems mentioned in the background art.
[0006] The solution to the above-mentioned technical problems provided by this utility model is as follows:
[0007] An electric pressure cooker with a safety locking lid protection device includes a pot body, an inner pot installed inside the pot body, and a lid installed on the pot body above the inner pot.
[0008] A control panel is provided on one side of the pot body, a power interface is provided on the side of the pot body away from the control panel, and a third handle is provided on both sides of the pot body, with a latch at both ends of the third handle.
[0009] The pot lid is provided with a reinforcing plate, and a first handle is installed on the reinforcing plate. The reinforcing plate is X-shaped, and a connecting plate is installed at the end of the reinforcing plate. A locking tongue is installed on the connecting plate. The pot lid push rod locking tongue and the lock buckle cooperate to lock and fix it to the pot body. A pressure relief valve is installed on the reinforcing plate near the connecting plate.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the top of the third handle is provided with a guard plate, which is located below the second handle. The guard plate is used to prevent the user from accidentally touching the second handle and being burned when moving the pot.
[0012] The beneficial effects of adopting the above-mentioned further solutions are:
[0013] By installing a protective plate at the top of the third handle, a physical heat insulation barrier is created. When moving the pot after cooking, even if the inner pot is still hot, the protective plate effectively blocks heat transfer from the second handle, preventing burns from accidental hand contact. This design fully considers user safety and scenario requirements, significantly improving product safety performance with simple structural optimization, reducing potential risks during use, and enhancing user trust in the product.
[0014] Furthermore, a second handle is provided at the edge of the inner pot, and the second handle is located on the outside of the lid and the pot body.
[0015] The beneficial effects of adopting the above-mentioned further solutions are:
[0016] The external design of the second handle greatly enhances the convenience of placing and removing the inner pot. Users can directly grasp the second handle on the outside when placing the inner pot before cooking or removing it after cooking, without needing to reach inside the pot or find other leverage points, reducing operational difficulty and time costs. At the same time, this layout avoids the risk of burns caused by frequent contact with the high-temperature areas inside the pot, and the position of the second handle makes it easier for users to apply force, allowing for more stable handling of the inner pot and preventing food spillage or slippage, thus balancing practicality and safety.
[0017] Furthermore, the first handle is located at the center of the reinforcing plate.
[0018] The beneficial effects of adopting the above-mentioned further solutions are:
[0019] The user experience of the pot lid has been optimized based on ergonomic principles. The first handle is positioned at the center of the reinforcing plate, ensuring that the user's hand pressure point coincides with the lid's center of gravity when opening and closing the lid. This effectively reduces lid wobbling or tilting caused by uneven force distribution, ensuring smooth and effortless operation. Simultaneously, the reinforcing plate's stable support for the first handle, combined with the centrally symmetrical force-bearing structure, disperses pressure during opening and closing, reduces wear at the handle-reinforcing plate connection, extends component lifespan, and further enhances product durability and user comfort.
[0020] Furthermore, the pot lid is equipped with several pressure relief valves, and the trigger pressure of the pressure relief valves increases sequentially.
[0021] The beneficial effects of adopting the above-mentioned further solutions are:
[0022] This system achieves precise and intelligent control of the pressure inside the pot. Multiple pressure relief valves with progressively increasing trigger pressures work in tandem to release steam in stages based on changes in pressure. When the pressure rises slightly, the valves with lower trigger pressures open first, releasing a small amount of steam promptly. If the pressure continues to rise, the valves with higher trigger pressures activate sequentially, increasing the steam release and preventing a single valve from failing due to pressure overload. This tiered pressure relief mechanism not only precisely maintains stable pressure inside the pot, ensuring safety during cooking, but also reduces the impact of sudden pressure changes on the cooking results, ensuring even heating and better taste. It also lowers the risk of safety accidents caused by uncontrolled pressure, significantly improving product reliability and cooking performance.
[0023] This utility model provides an electric pressure cooker with a safety locking lid protection device. It has the following beneficial effects:
[0024] Featuring a locking tongue and latch design, the lid precisely aligns and locks shut when lowered, forming a stable mechanical locking structure. This design effectively prevents the lid from accidentally popping open due to pressure fluctuations during cooking. Compared to traditional simple latch structures, it significantly reduces safety hazards and provides users with reliable safety assurance.
[0025] The pot lid is equipped with multiple pressure relief valves that open sequentially according to their pressure levels as the pressure inside the pot rises. This tiered pressure relief method allows for more precise regulation of the pressure inside the pot, preventing the risk of explosion due to excessive pressure, while ensuring that the cooking process is carried out within a safe pressure range, thus improving the overall safety of the product.
[0026] The protective plate at the top of the third handle on the pot body is located below the second handle on the inner pot. When moving the pot, it effectively blocks the heat transmitted from the second handle, preventing users from being burned by accidental contact. This design fully considers user operating scenarios and improves safety in the details.
[0027] The X-shaped reinforcing plate on the lid not only provides a stable mounting base for the handle but also enhances the overall structural strength of the lid. During opening and closing, the reinforcing plate effectively distributes the force, preventing deformation due to uneven stress, extending the lid's lifespan, and ensuring operational stability.

[0035] 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.
[0036] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:
[0037] Example 1
[0038] An electric pressure cooker with a safety locking cover protection device includes a pot body 3, an inner pot 2 installed inside the pot body 3, a pot cover 1 installed on the pot body 3 above the inner pot 2, a control board 301 on one side of the pot body 3, a power interface 305 on the side of the pot body 3 away from the control board 301, and a third handle 303 on both sides of the pot body 3, with a latch 302 at both ends of the third handle 303.
[0039] The pot lid 1 is equipped with a reinforcing plate 104, on which a first handle 101 is mounted. The first handle 101 is located at the center of the reinforcing plate 104, optimizing the user experience of the pot lid 1 based on ergonomic principles. By placing the first handle 101 at the center of the reinforcing plate 104, the user's hand application point is basically aligned with the center of gravity of the pot lid 1 when opening and closing the lid, effectively reducing the shaking or tilting of the pot lid 1 caused by uneven force, and ensuring a smooth and effortless operation. Meanwhile, the reinforcing plate 104 provides stable support for the first handle 101. Combined with the centrally symmetrical force-bearing structure, this disperses pressure during opening and closing, reduces wear at the connection between the handle and the reinforcing plate 104, extends component lifespan, and further enhances product durability and user comfort. The reinforcing plate 104 is X-shaped, and a connecting plate 102 is installed at its end. A locking tongue 103 is installed on the connecting plate 102. The locking tongue 103 and the latch 302 of the lid 1 are sequentially engaged and locked onto the pot body 3. A pressure relief valve 4 is installed on the reinforcing plate 104 near the connecting plate 102. Several pressure relief valves 4 are installed on the lid 1, with their trigger pressures increasing sequentially, achieving precise and intelligent control of the pressure inside the pot. Multiple pressure relief valves 4 with increasing trigger pressures work together to release steam in stages according to changes in the pressure inside the pot. When the pressure rises slightly, the pressure relief valve 4 with the low trigger pressure opens first, releasing a small amount of steam in a timely manner. If the pressure continues to rise, the pressure relief valves 4 with the high trigger pressure activate sequentially, increasing the steam release and preventing a single pressure relief valve 4 from failing due to pressure overload. This tiered pressure relief mechanism not only precisely maintains stable pressure inside the pot, ensuring safety during cooking, but also reduces the impact of sudden pressure changes on the cooking effect, ensuring even heating and better taste. It also reduces the risk of safety accidents caused by uncontrolled pressure, significantly improving product reliability and cooking performance.
[0040] Example 2
[0041] To improve the ease of removing and placing the inner liner, enhance safety, and optimize the user experience, for example, such as Figures 1 to 3As shown, this utility model also includes: a second handle 201 is provided at the edge of the inner pot 2, and the second handle 201 is located on the outside of the lid 1 and the pot body 3. The external design of the second handle 201 greatly improves the convenience of placing and removing the inner pot 2. When placing the inner pot 2 before cooking or removing the inner pot 2 after cooking, the user can directly hold the second handle 201 located on the outside without having to reach into the pot body 3 or find other points of leverage, reducing the difficulty of operation and time cost. At the same time, this layout avoids the risk of burns caused by frequent contact with the high-temperature area inside the pot body 3, and the position of the second handle 201 makes it easy for the user to apply force, enabling more stable handling of the inner pot 2 and preventing food spillage or slippage of the inner pot 2, thus balancing practicality and safety. The top of the third handle 303 is provided with a protective plate 304, and the protective plate 304 is located below the second handle 201. The protective plate 304 is used to prevent the user from accidentally touching the second handle 201 and being burned when moving the pot body 3. By setting the protective plate 304 at the top of the third handle 303, a physical heat insulation protection barrier is constructed. When the electric pressure cooker finishes cooking and the pot body 3 is moved, even if the inner pot 2 is still at a high temperature, the protective plate 304 can effectively block the heat transmitted by the second handle 201, preventing users from being burned due to accidental contact with the second handle 201. This design fully considers the safety of user operation and the needs of different scenarios, significantly improving the product's safety performance with simple structural optimization, reducing potential risks during use, and enhancing users' trust in the product.
[0042] Working principle:
[0043] Place the inner pot 2 inside the pot body 3, ensuring it is stably positioned. At this point, the second handle 201 on the edge of the inner pot 2 is exposed on the outside of the lid 1 and the pot body 3, facilitating the subsequent removal and placement of the inner pot 2. Simultaneously, the tops of the third handles 303 on both sides of the pot body 3 are equipped with protective plates 304, positioned precisely below the second handles 201, providing anti-scalding protection when moving the pot body 3 and preventing users from accidentally touching the second handles 201 and being burned.
[0044] The user holds the first handle 101 at the center of the reinforcing plate 104 on the lid 1, and smoothly places the lid 1 onto the pot body 3. The reinforcing plate 104 has an X-shaped structure, providing stable support for the lid 1 and facilitating the installation of other components. As the lid 1 falls, the locking tongue 103 installed on the connecting plate 102 at the end of the reinforcing plate 104 gradually aligns with the latches 302 at both ends of the third handle 303 on the pot body 3. When the lid 1 is fully in place, the locking tongue 103 and the latches 302 engage and lock, achieving a mechanical lock between the lid 1 and the pot body 3. This design, through the precise alignment and engagement of the locking tongue 103 and the latches 302, ensures that the lid 1 is tightly fixed to the pot body 3, preventing the lid 1 from accidentally opening during cooking.
[0045] Turn on the electric pressure cooker and set the cooking program via the control panel 301 on one side of the pot body 3. The power interface 305 supplies power to the device. During cooking, the pressure inside the pot gradually increases. When the pressure reaches the trigger pressure of the first pressure relief valve 4, this valve 4 opens first, releasing some steam to prevent excessive pressure rise. If the pressure continues to rise, multiple subsequent pressure relief valves 4 with progressively increasing trigger pressures will open in sequence to further regulate the pressure inside the pot, ensuring that the pressure is always maintained within a safe range. This multi-stage pressure relief valve design allows for more precise control of the pressure inside the pot, improving cooking safety and stability.
