Description

Technical Field

[0001] This utility model relates to kitchenware, and more particularly to a pot lid opening and closing structure that is easy to open. Background Technology

[0002] A pressure cooker, also called a pressure vessel, works on a simple principle: the boiling point of water is affected by air pressure. The higher the pressure, the higher the boiling point. When the pressure is less than one atmosphere, water boils at less than 100°C, while when the pressure is greater than one atmosphere, water boils at a temperature above 100°C. Common pressure cookers are designed based on this principle. Using a pressure cooker not only shortens cooking time but also improves the taste of cooked food, thus enhancing people's quality of life. Currently, most pressure cookers on the market rely on a rotating mechanism to overcome significant static friction when opening and closing the lid, lacking effective force-saving mechanisms and convenient operation designs, thus requiring improvement. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing pot lids, such as the inconvenience of opening or closing them, by providing a new pot lid opening and closing structure that is easy to open.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: An easy-to-open pot lid opening and closing structure includes a pot lid body, which includes a lid body, a lid shell, and a handle. The lid body and the lid shell are connected in a detachable manner by double-headed bolts, and a movable space is formed between the lid shell and the lid body. The handle is movably connected to the lid shell. The structure also includes a clamping assembly and a control assembly. The control assembly is disposed within the movable space, and the lower end of the handle is movably connected to the control assembly. The clamping assembly includes a first clamping ear and a second clamping ear, which are respectively disposed opposite to each other at the edge of the lid body and are both connected to the control assembly to form a clamping state or a relaxed state, controlling the opening or closing of the handle, thereby allowing the first clamping ear and the second clamping ear to switch between clamping and relaxed states synchronously.

[0005] This application links the clamp assembly and the control assembly, so that simply opening or closing the control handle can synchronously control the first and second clamping ears of the clamp assembly to switch between clamping and releasing states.

[0006] Preferably, in the above-described easy-to-open pot lid opening and closing structure, the control component includes a fixed plate and a movable plate located above the fixed plate. The fixed plate has fixed ears on both sides, which are respectively fixed with corresponding double-headed bolts. The fixed plate has a first sliding groove, and the movable plate has first sliders on both sides. The first sliders of the movable plate are respectively movably connected to the corresponding first sliding grooves.

[0007] The control component uses a split structure of "fixed plate + movable plate" and a fixing method of "fixed ears and double-headed bolts" to achieve a detachable connection between the control component and the pot lid body, which facilitates the maintenance or replacement of the control component in the future.

[0008] Preferably, in the above-described easy-to-open pot lid opening and closing structure, the fixed plate is provided with a second sliding groove, the movable plate is provided with a fixing hole, and the lower end of the handle is provided with a fixing post, which passes through the fixing hole and cooperates with the second sliding groove.

[0009] By using a structure in which a fixed post passes through a fixed hole in the movable plate and engages with the second groove of the fixed plate, the mechanical action of the handle, "opening or closing," is precisely converted into the linear movement of the movable plate, thus achieving effective transmission of the action, avoiding disconnection between the handle operation and the movement of the movable plate, and ensuring reliable execution of control commands.

[0010] Preferably, in the above-described easy-to-open pot lid opening and closing structure, the first clamping ear includes a first connecting part and a first clamping part, and the second clamping ear includes a second connecting part and a second clamping part. The first connecting part and the second connecting part are stacked between the cover and the fixing plate, and a third sliding groove is provided on both the first connecting part and the second connecting part, and the third sliding groove is engaged with a double-headed bolt; The first clamping part and the second clamping part respectively engage with the edge of the cover.

[0011] The clamping ear is divided into a modular structure of "connecting part + clamping part", which facilitates the individual processing and assembly of each component and reduces the difficulty of production and manufacturing. At the same time, the clamping part is specifically designed to fit the edge of the cover, and the clamping contact surface can be optimized according to the shape of the cover edge to improve the clamping sealing and stability.

[0012] Preferably, in the above-described easy-to-open pot lid opening and closing structure, the first connecting part and the second connecting part are further provided with sliding columns; The fixed plate is also provided with a fourth sliding groove, and the movable plate is provided with a fifth sliding groove at a position corresponding to the fourth sliding groove. The sliding column passes through the fourth sliding groove from bottom to top and then cooperates with the fifth sliding groove. The fifth slide is set at an angle.

[0013] The inclined fifth slide is the core transmission optimization structure: when the movable plate moves, the fifth slide generates "lateral thrust or pull" on the connection part of the clamping ear through the sliding column, which efficiently converts the linear motion of the movable plate into the opening and closing motion of the clamping ear, realizing "small stroke driving large clamping action", further reducing the operating force and improving the labor saving effect.

[0014] As a preferred embodiment, the above-described easy-to-open pot lid opening and closing structure includes a locking device on the lid body. The locking device includes a mounting base and a locking rod, and the locking rod is movably mounted on the mounting base to form a locked state and an unlocked state. Both the first connecting part and the second connecting part have locking holes at positions corresponding to the locking rod. When in the locked state, the locking rod engages with the locking hole, and when in the unlocked state, the locking rod disengages from the locking hole.

[0015] The locking device solves the risk of existing pot lids not having a safe lock and being easily opened or closed accidentally: In the locked state, the locking rod is inserted into the locking hole of the connecting part to fix the position of the clamping ear. This can prevent the pot lid from bursting open due to accidental loosening of the clamping ear when the pressure inside the pot has not been released (such as during the heating process of a pressure cooker), or from leaking air due to displacement of the clamping ear during transportation, thus greatly improving the safety of use.

[0016] Preferably, in the above-described easy-to-open pot lid opening and closing structure, the fixed plate is also provided with a slide rail, and the movable plate is provided with a sixth slide groove at a position corresponding to the slide rail, the sixth slide groove cooperating with the slide rail.

[0017] The fixed plate slide rail and the sixth slide groove of the movable plate form an additional guiding fit structure, which together with the "first slider and first slide groove" form a double guiding constraint, further restricting the degree of freedom of movement of the movable plate, completely avoiding shaking, deviation or jamming when the movable plate moves, and improving the movement stability and service life of the control components.

[0018] Preferably, in the above-described easy-to-open pot lid opening and closing structure, the lid shell has a receiving groove, the handle is disposed in the receiving groove, and the handle is provided with a toggle block.

[0019] The lid's recessed compartment can house the handle, preventing it from protruding from the lid's surface and reducing the risk of damage during transport or storage. It also makes the lid's overall appearance simpler and neater, reducing space usage.

[0020] Preferably, the aforementioned easy-to-open pot lid opening and closing structure also includes a pressure relief valve on the lid body.

[0021] The pressure relief valve can balance the air pressure inside and outside the pot lid in real time: when the pressure inside the pot is too high, the pressure relief valve will automatically release the excess pressure to avoid deformation, damage or safety accidents caused by excessive pressure, thus improving the safety of product use.

[0022] The present invention has the following advantages through the above structural improvements: Compared with conventional pot lids, this application has the advantage of being easy to open. Through the linkage structure of "handle-control component-clamping component", only the opening or closing of the handle is required to drive the first clamping ear and the second clamping ear to switch between clamping and releasing states synchronously. There is no need to operate multiple parts separately, which greatly simplifies the opening and closing steps and improves the convenience of operation. In addition, the synchronous control design avoids the problem of delayed or misaligned action of individual clamping ears, ensuring that the force on the edge of the pot lid is even, improving the sealing performance and opening and closing stability, and reducing the risk of the pot lid loosening or leaking due to uneven clamping.

[0025] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention: Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an easy-to-open pot lid opening and closing structure includes a pot lid body 1, which includes a lid body 11, a lid shell 12, and a handle 13. The lid body 11 and the lid shell 12 are connected by double-headed bolts to form a detachable connection, and a movable space is formed between the lid shell 12 and the lid body 11. The handle 13 is movably connected to the lid shell 12. The characteristic feature is that it also includes a clamping assembly 2 and a control assembly 3. The control assembly 3 is disposed in the movable space. The lower end of the handle 13 is movably connected to the control assembly 3. The clamping assembly 2 includes a first clamping ear 21 and a second clamping ear 22. The first clamping ear 21 and the second clamping ear 22 are respectively disposed opposite to each other at the edge of the lid body 11, and both are connected to the control assembly 3 to form a clamping state or a relaxed state, controlling the opening or closing of the handle 13, so that the first clamping ear 21 and the second clamping ear 22 can switch between clamping state and relaxed state synchronously.

[0027] Preferably, the control component 3 includes a fixed plate 31 and a movable plate 32 located above the fixed plate 31. The fixed plate 31 has fixed ears 311 on both sides, which are respectively fixed with corresponding double-headed bolts. The fixed plate 31 has a first sliding groove 312. The movable plate 32 has first sliders 321 on both sides, and the first sliders 321 of the movable plate 32 are respectively movably connected to the corresponding first sliding grooves 312.

[0028] Furthermore, the first slider 321 of the movable plate 32 and the first slide groove 312 of the fixed plate 31 form a precise guiding fit, which restricts the movement trajectory of the movable plate 32, avoids deviation or jamming when the movable plate 32 moves, and ensures the movement accuracy of the first slider 321 and the first slide groove 312, laying the foundation for the subsequent stable driving of the clamp assembly 2 to switch states.

[0029] Preferably, the fixed plate 31 is provided with a second sliding groove 313, the movable plate 32 is provided with a fixing hole 322, and the lower end of the handle 13 is provided with a fixing post 131. The fixing post 131 passes through the fixing hole 322 and cooperates with the second sliding groove 313.

[0030] Furthermore, the cooperation between the second slide groove 313 and the fixed column 131 can further optimize the motion constraint of the movable plate 32, prevent the movable plate 32 from shaking during movement, improve the operational stability of the control component 3, and indirectly ensure the accuracy of the clamp component 2 in switching between clamping and releasing states.

[0031] Preferably, the first clamping ear 21 includes a first connecting portion 211 and a first clamping portion 212, and the second clamping ear 22 includes a second connecting portion 221 and a second clamping portion 222; The first connecting part 211 and the second connecting part 221 are stacked between the cover 11 and the fixing plate 31, and a third sliding groove 23 is provided on both the first connecting part 211 and the second connecting part 221. The third sliding groove 23 is engaged with a double-headed bolt. The first clamping part 212 and the second clamping part 222 respectively engage with the edge of the cover 11.

[0032] Furthermore, the first connecting part 211 and the second connecting part 221 are stacked between the lid 11 and the fixing plate 31, which can effectively avoid the structure occupying extra space and ensure the overall compactness of the pot lid; Meanwhile, the cooperation between the third slide groove 23 and the double-headed bolt provides sliding guidance for the first clamping ear 21 and the second clamping ear 22, ensuring that the first clamping ear 21 and the second clamping ear 22 move smoothly and avoid jamming.

[0033] Preferably, the first connecting portion 211 and the second connecting portion 221 are further provided with sliding pins 4; The fixed plate 31 is also provided with a fourth sliding groove 315, and the movable plate 32 is provided with a fifth sliding groove 323 at a position corresponding to the fourth sliding groove 315. The sliding column 4 passes through the fourth sliding groove 315 from bottom to top and then cooperates with the fifth sliding groove 323. The fifth slide groove 323 is set at an angle.

[0034] Furthermore, the sliding column 4, together with the fourth sliding groove 315 of the fixed plate 31 and the fifth sliding groove 323 of the movable plate 32, forms a double guiding constraint to prevent the first clamping ear 21 and the second clamping ear 22 from deviating during the movement, ensuring the consistency of the synchronous movement of the first clamping ear 21 and the second clamping ear 22, and improving the stability and accuracy of the opening and closing action.

[0035] Preferably, the cover 11 is provided with a locking device 5, which includes a mounting base 51 and a locking rod 52. The locking rod 52 is movably mounted on the mounting base 51 to form a locked state and an unlocked state. Both the first connecting part 211 and the second connecting part 221 have locking holes 6 at positions corresponding to the locking rod 52. When in the locked state, the locking rod 52 engages with the locking hole 6, and when in the unlocked state, the locking rod 52 disengages from the locking hole 6.

[0036] Furthermore, due to the movable connection design between the locking rod 52 and the mounting base 51, when the pressure inside the pot is too high, the locking rod 52 will be pushed upward. At this time, the locking rod 52 will engage with the locking hole 6, and the pot lid cannot be opened. When the pressure inside the pot decreases, the locking rod 52 will automatically fall down. At this time, the locking rod 52 will disengage from the locking hole 6, and the pot lid can be opened.

[0037] Preferably, the fixed plate 31 is also provided with a slide rail 316, and the movable plate 32 is provided with a sixth slide groove 324 at a position corresponding to the slide rail 316, and the sixth slide groove 324 cooperates with the slide rail 316.

[0038] Furthermore, the dual guide design formed by the "slide rail 316 and the sixth slide groove 324" and the "first slide groove 312 and the first slider 321" ensures that the moving plate can maintain a precise movement trajectory after long-term use, avoids motion transmission failure caused by wear of a single guide structure, indirectly ensures the reliability of the clamp assembly's clamping or releasing state switching, and improves product durability.

[0039] Preferably, the cover 12 has a receiving groove 121, the handle 13 is disposed in the receiving groove 121, and the handle 13 is provided with a toggle block 133.

[0040] Furthermore, the toggle block 133 on the handle 13 provides the user with a clear point of force application, eliminating the need to directly pry off the handle 13 body. This allows the user to quickly and effortlessly drive the handle 13 to open or close, especially for users with less strength, such as the elderly and women. This significantly improves the feel and convenience of operation, solving the pain point of the existing handle 13 being difficult to operate.

[0041] Preferably, the cover 11 is also provided with a pressure relief valve 7.

[0042] Furthermore, the pressure relief valve 7 can release the residual pressure inside the pot in advance, avoiding the need to overcome air pressure resistance when opening and closing due to excessive pressure inside the pot, further reducing the force required for opening and closing, and making it easier to open the pot lid.

[0043] Specifically, when the lid of this embodiment needs to be opened, it is first necessary to confirm whether the locking rod 52 is in the unlocked state. Then, the handle 13 is pushed upward to open it. At this time, the fixing post 131 of the handle 13 will drive the movable plate 32 to move. When the movable plate 32 moves, the sliding post 4 on the first clamping ear 21 and the second clamping ear 22 of the clamping assembly 2 will also move synchronously. At this time, the first clamping ear 21 and the second clamping ear 22 will expand outward to form a relaxed state, thereby making the lid relaxed. When the lid needs to be closed, simply push the handle 13 downward to close it. Other components will move in the opposite direction, thereby making the first clamping ear 21 and the second clamping ear 22 clamp. At this time, the lid is closed and clamped, and the locking rod 52 will lock with the locking hole 6 under the pressure inside the pot.

[0044] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
