Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a pot lid and a pot. Background Technology

[0002] A cookware clamp assembly is a mechanical device used to lock the lid to the pot body. Its core function is to ensure the cookware's airtightness and safety during cooking by clamping or releasing the edge of the pot. The clamps on the lid can move relative to the pot body to achieve a clamped or open state. However, existing clamps involve complex operation steps when switching between clamped and open states, resulting in a poor user experience. Utility Model Content

[0003] This application provides a pot lid and cookware that facilitates the switching of the clamping assembly between a clamping state and an open state, thereby improving the user experience.

[0004] This application provides a pot lid, which includes a lid body and a clamp assembly. The clamp assembly includes a drive member, a linkage mechanism, and at least two clamps, which are movable relative to the lid body. The linkage mechanism is connected to the at least two clamps and is also connected to the drive member.

[0005] The driving member can move relative to the lid along the height direction of the pot lid, so as to drive the clamps to move closer or further apart along the first direction X through the linkage mechanism, so that the clamp assembly is in a clamped state or an open state.

[0006] In this solution, on the one hand, the user only needs to press the drive component to open or close the clamp assembly, which has the advantage of convenient operation. On the other hand, the linkage mechanism can convert the vertical movement of the drive component into the radial reciprocating motion of the clamp, which can increase the movement stroke of the clamp in a small space. Moreover, the linkage mechanism that realizes this conversion of movement direction not only has the advantage of simple structure, but also facilitates the control of movement trajectory, thereby improving the reliability of clamp movement.

[0007] On the other hand, when the clamping assembly is in the clamping or open state, the position of the linkage mechanism is relatively stable, which improves the smoothness of the clamping movement, reduces the impact damage caused by sudden changes in the position of the clamp, and improves the stability of the fit between the lid and the pot body, thereby reducing the risk of the lid falling off and increasing the service life of the lid.

[0008] Optionally, the linkage mechanism includes at least two links, one end of each of the at least two links is rotatably connected to the drive member, and the other end of each of the at least two links is rotatably connected to at least two clamps.

[0009] In this design, the connecting rod is rotatably connected to the drive unit and the clamp, which can reduce mechanical vibration and noise during the movement, improve the smoothness of the clamp assembly movement, reduce friction loss during the transmission of the clamp assembly, improve the transmission efficiency between the drive unit and the clamp, reduce the risk of fatigue fracture of the connecting rod, and increase the service life of the pot lid.

[0010] Optionally, the linkage mechanism further includes at least two moving parts, one end of which is connected to the clamp, and the other end of which is rotatably connected to the linkage.

[0011] In this design, a linkage drives the moving parts, thereby achieving an indirect rotational connection between the linkage and the clamp. When the linkage and clamp are indirectly connected via the moving parts, there is no need to increase the volume of the linkage and clamp, thus reducing the space occupied by them and consequently decreasing the size of the clamp assembly and the lid.

[0012] Optionally, the clamp assembly further includes an elastic element, the two ends of which are respectively connected to the two moving parts, and the elastic element is used to maintain the clamp assembly in the clamped state or the open state.

[0013] In this solution, when the clamp assembly is in the clamping state, it can automatically return to the clamping state, thereby preventing the user from accidentally touching the drive component and causing the drive component to drive the clamp to open accidentally through the linkage mechanism, thus improving the reliability and stability of the clamp assembly in the clamping state. When the clamp assembly is in the open state, the forces on the two linkages are balanced, thereby preventing the user from accidentally touching the drive component and causing the drive component to drive the clamps to move closer to each other through the linkage mechanism, thus improving the reliability and stability of the clamp assembly in the open state.

[0014] Optionally, in the open state, the inclination angle of the two links relative to the horizontal plane is α, where 1°≤α≤10°.

[0015] In this design, when 1°≤α≤10° is satisfied, the downward tilt angle α of the two connecting rods relative to the horizontal surface of the pot lid is moderate, which can improve the stability of the clamp assembly when it is open, while also improving the user's ease of operation and the space utilization of the pot lid.

[0016] Optionally, the drive member has a first connecting portion extending along the height direction of the pot lid, and the connecting rod is rotatably connected to the first connecting portion.

[0017] In this design, when the user presses the drive component, the first connecting part moves downward, thereby causing the linkage mechanism to rotate. Furthermore, the first connecting part protects the linkage structure, reducing impact damage to the linkage from other components during transportation or accidental collisions.

[0018] Optionally, the linkage mechanism includes a first link, a second link, a first moving member, and a second moving member. The first link is rotatably connected to the first moving member and the driving member, and the second link is rotatably connected to the second moving member and the driving member. The first moving member and the second moving member are respectively connected to the two clamps.

[0019] The clamp assembly includes two elastic elements, the two ends of which are respectively connected to the first moving element and the second moving element. Along the second direction Y, the first connecting rod and the second connecting rod are located between the two elastic elements.

[0020] In this design, the elastic elements are arranged along the second direction Y on the outside of the two connecting rods, providing ample space for the movement of the connecting rods. Furthermore, the two elastic elements distributed along the second direction Y can ensure high stability and reliability of the effect of the elastic elements on the moving parts.

[0021] Optionally, the clamp assembly further includes a base having a guide groove extending along the height direction of the lid, and the drive member having a guide portion extending radially outward therefrom, the guide portion being slidable along the guide groove.

[0022] In this design, a base is provided to protect the structure of the driving component, reducing the risk of damage. The base also facilitates the user's handling of the pot lid. Furthermore, the sliding fit between the guide and the guide groove improves the stability and reliability of the driving component's movement along the height direction, thereby enhancing the stability and reliability of the linkage mechanism's rotation. This, in turn, improves the reliability of the clamps moving closer and further apart along the first direction X.

[0023] Optionally, the clamp assembly further includes a cover plate for connection with the cover body, the linkage mechanism being mounted between the cover plate and the cover body, and the cover plate having a through hole through which a portion of the linkage mechanism and the first connecting portion can pass.

[0024] In this design, the cover plate protects the linkage mechanism, and the through holes in the cover plate provide ample space for the drive components and linkage mechanism to move.

[0025] Optionally, the clamp assembly further includes a fixing member connected to the moving member and the cover plate by a fastener, the moving member having a clearance hole for avoiding the fastener.

[0026] In this design, the clamp assembly is fixedly connected to the cover plate using fasteners, thus mounting the entire clamp assembly onto the lid. Mounting the entire clamp assembly onto the lid offers the advantage of easy installation and reduces the decrease in installation accuracy caused by the accumulation of tolerances when individual components are mounted separately. Furthermore, the clearance hole provided on the moving part allows the fastener to be cleared when the moving part moves along the first direction X, preventing the fastener from obstructing the movement of the moving part along the first direction X, and enabling the clamp assembly to be in either a clamped or open state.

[0027] This application also provides a cookware, which includes a pot body and a pot lid, the pot lid being closed onto the opening of the pot body.

[0070] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0071] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0072] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0073] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0074] This application provides a cookware, which includes a pot body and a lid, the lid of which can be closed onto the opening of the pot body. The lid has clamps that can clamp the lid and the pot body tightly when the lid is attached to the pot body.

[0075] In some embodiments, the specific type of cookware may be a rice cooker, a multi-functional cooker, a pressure cooker, etc. This application does not limit the specific type of cookware.

[0076] The following description uses a pressure cooker as an example.

[0077] like Figures 1-3As shown, this application embodiment provides a pot lid that can be applied to a pot body. The pot lid includes a lid body 1 and a clamp assembly 2. The clamp assembly 2 includes a driving member 21, a linkage mechanism 22, and at least two clamps 23. The clamps 23 are movably connected to the lid body 1, and the linkage mechanism 22 is connected to the at least two clamps 23 and the driving member 21. The driving member 21 can move relative to the lid body 1 along the height direction of the pot lid, so as to drive the clamps 23 to move closer or further apart along a first direction X via the linkage mechanism 22, so that the clamp assembly 2 is in a clamped state or an open state. The first direction X can be the radial direction of the pot lid, that is, the at least two clamps 23 are distributed radially along the lid.

[0078] like Figure 1 As shown, the lid 1 is used to cover the opening of the pot body. The lid 1 is provided with a sealing ring, which can form a seal between the lid and the pot body. The clamp assembly 2 includes at least two clamps 23, which are movably connected to the lid 1 along the first direction X, and the at least two clamps 23 are spaced apart circumferentially along the lid 1. Figure 5 As shown, when at least two clamps 23 approach each other along the first direction X, at least two clamps 23 approach the lid 1, and the clamp assembly 2 is in a clamping state, that is, the clamps 23 clamp the lid and the pot body, restricting the lid from separating from the pot body, so that the cooking space of the pot is sealed, allowing the pressure inside the pot to increase and improving cooking efficiency. Figure 6 As shown, when at least two clamps 23 move away from each other along the first direction X, at least two clamps 23 move away from the lid 1, and the clamp assembly 2 is in the open state, that is, the lid and the pot body can be separated from each other, and the user can open the lid.

[0079] like Figure 2 and Figure 3 As shown, the clamp assembly 2 also includes a drive member 21 and a linkage mechanism 22, with the linkage mechanism 22 connected to both the drive member 21 and the clamp 23. Figure 5 As shown, when the driving component 21 moves upward along the height direction of the lid 1, it drives the linkage mechanism 22 to drive the clamps 23 to move closer to each other along the first direction X. Each clamp 23 approaches the lid 1, and the clamp assembly 2 is in a clamping state, that is, the clamps 23 clamp the lid and the pot body; Figure 6 As shown, when the driving component 21 moves downward along the height direction of the lid 1, it drives the linkage mechanism 22 to drive the clamps 23 to move away from each other along the first direction X. Each clamp 23 moves away from the lid 1, and the clamp assembly 2 is in the open state, that is, the lid and the pot body can be separated from each other.

[0080] In this embodiment, the movement of the driving member 21 relative to the lid 1 along the height direction of the lid drives the linkage mechanism 22 to drive the clamps 23 to move closer or further apart in the radial direction X of the lid 1. This means the user only needs to press the driving member 21 to open or close the clamp assembly 2, offering the advantage of convenient operation. Furthermore, the movement of the driving member 21 along the height direction is transmitted to the clamps 23 through the linkage mechanism 22, causing the clamps 23 to move radially. In other words, the linkage mechanism 22 can convert the movement of the driving member 21 along the height direction into the radial reciprocating motion of the clamps 23. This increases the stroke of the clamps 23 within a smaller space. Moreover, the linkage mechanism 22, which realizes this conversion of movement direction, not only has the advantage of simple structure but also facilitates control of the movement trajectory, thereby improving the reliability of the clamps 23's movement.

[0081] When the clamp assembly 2 is in the clamping or open state, the position of the linkage mechanism 22 is relatively stable, which improves the smoothness of the movement of the clamp 23, reduces the impact damage caused by sudden changes in position of the clamp 23, and improves the stability of the fit between the lid and the pot body, thereby reducing the risk of the lid falling off and increasing the service life of the lid.

[0082] The specific structure of the driving component 21 can be a button structure, which enables the driving component 21 to move along the height direction of the pot lid.

[0083] In other embodiments, the specific structure of the driving member 21 may also be a sliding member, a rotating member, etc. This application does not limit the specific structure of the driving member 21.

[0084] In some embodiments, such as Figure 2 As shown, the linkage mechanism 22 includes at least two links 221, one end of each of the at least two links 221 is rotatably connected to the drive member 21, and the other end of each of the at least two links 221 is rotatably connected to at least two clamps 23.

[0085] When the drive component 21 moves along the height direction, it drives the two connecting rods 221 to rotate in the vertical plane, thereby changing the angle between the connecting rods 221 and the horizontal plane, and further driving the clamps 23 to move along the first direction X, so that the clamps 23 can move closer to or further away from each other. The connecting rods 221 are rotatably connected to the drive component 21 and the clamps 23 respectively, which can reduce mechanical vibration and noise during the movement, improve the smoothness of the movement of the clamp assembly 2, reduce friction loss during the transmission process of the clamp assembly 2, improve the transmission efficiency between the drive component 21 and the clamps 23, reduce the risk of fatigue fracture of the connecting rods 221, and improve the service life of the pot lid.

[0086] Specifically, one end of at least two connecting rods 221 is rotatably connected to the drive member 21 via a pivot, and the other end of at least two connecting rods 221 is rotatably connected to at least two clamps 23 via pivots respectively. In some other embodiments, the connection method between the connecting rods 221 and the drive member 21 and / or the clamps 23 may also be ball bearings, bolt connections, etc. This application does not limit the specific connection method between the connecting rods 221 and the drive member 21 and / or the clamps 23.

[0087] In one specific embodiment, the connecting rod 221 and the clamp 23 can be directly connected or indirectly connected. For example, when the connecting rod 221 and the clamp 23 are directly connected, the number of components in the clamp assembly 2 can be reduced, making the movement of the clamp 23 more accurate. In this case, the size of the connecting rod 221 or the clamp 23 is relatively large. When the connecting rod 221 and the clamp 23 are indirectly connected, a moving member 222 is provided between the connecting rod 221 and the clamp 23. That is, both ends of the moving member 222 are connected to the connecting rod 221 and the clamp 23 respectively. One end of the moving member 222 is rotatably connected to the connecting rod 221, and the other end of the moving member 222 is fixedly or detachably connected to the clamp 23. When the connecting rod 221 rotates under the drive of the driving member 21, it can drive the moving member 222 to move along the first direction X, and then drive the clamp 23 to move along the first direction X through the moving member 222.

[0088] This embodiment will be described using the example of setting a moving part 222 between the connecting rod 221 and the clamp 23 to achieve an indirect rotational connection between the connecting rod 221 and the clamp 23.

[0089] In the above embodiments, as Figure 2 and Figure 3 As shown, the linkage mechanism 22 also includes at least two moving parts 222, one end of which is connected to the clamp 23, and the other end of which is rotatably connected to the linkage 221.

[0090] like Figure 2 and Figure 3 As shown, at least two moving parts 222 are distributed along the first direction X of the pot lid, and the movement direction of the moving parts 222 is consistent with the movement direction of the clamps 23. The moving parts 222 are driven by the connecting rod 221, thereby realizing the indirect rotational connection between the connecting rod 221 and the clamps 23. In this embodiment, when the connecting rod 221 and the clamps 23 are indirectly rotated through the moving parts 222, it is not necessary to increase the volume of the connecting rod 221 and the clamps 23, so that the connecting rod 221 and the clamps 23 do not occupy too much space, thereby reducing the volume of the clamp assembly 2 and the pot lid.

[0091] Specifically, the moving part 222 can be a plate structure. In other embodiments, the moving part 222 can also be a columnar structure, a strip structure, etc. This application does not limit the specific structure of the moving part 222.

[0092] In some embodiments, such as Figure 2 and Figure 3 As shown, the clamp assembly 2 may further include an elastic element 24, with both ends of the elastic element 24 connected to two moving parts 222 respectively, meaning the elastic deformation direction of the elastic element 24 is the first direction X. Figure 5 and Figure 6 As shown, the elastic element 24 is used to limit the rotation of the linkage 221 so that the clamp assembly 2 can be maintained in the clamped or open state.

[0093] like Figure 5 and Figure 6 As shown, each elastic element 24 is connected between two moving elements 222. The two connecting rods 221 and the elastic elements 24 form an approximately triangular structure, that is, the ends of the two connecting rods 221 near the driving element 21 form the apex angle of the triangle, and the other ends of the two connecting rods 221 and the elastic elements 24 form the base angle of the triangle. Figure 5 As shown, when the clamp assembly 2 is in the clamping state, the two moving parts 222 approach each other. At this time, under the action of the elastic element 24, the connection position of the two connecting rods 221 is subjected to an upward force along the height direction, thereby restricting the downward movement of the connecting rods 221. When the user accidentally touches the drive element 21, the connecting rods 221 rotate downward but do not reach the desired position. Figure 6 When in the position shown (the open position), under the action of the elastic element 24, the connecting rod 221 can automatically rotate to... Figure 5 As shown, the clamp assembly 2 can automatically return to the clamping state, thereby preventing the user from accidentally touching the drive component 21, which would cause the drive component 21 to drive the clamp 23 to open accidentally through the linkage mechanism 22, thus improving the reliability and stability of the clamp assembly 2 in the clamping state.

[0094] like Figure 6 As shown, when the clamp assembly 2 is in the open state, the two moving parts 222 are far apart from each other. At this time, the elastic element 24 remains in the stretched state. Under the action of the elastic element 24, the position where the two connecting rods 221 are connected is subjected to a downward force along the height direction, thereby restricting the upward movement of the connecting rods 221. At this time, the forces on the two connecting rods 221 are balanced, thereby preventing accidental contact with the drive element 21 from causing the drive element 21 to drive the clamps 23 to move closer to each other through the linkage mechanism 22, thus improving the reliability and stability of the clamp assembly 2 in the open state.

[0095] The elastic element 24 can be a tension spring. In other embodiments, the elastic element 24 can also have other structures. This application does not limit the specific structure of the elastic element 24.

[0096] In some embodiments, such as Figure 7As shown, when the clamp assembly 2 is in the open state, the inclination angle of the two connecting rods 221 relative to the horizontal surface of the pot lid is α, 1°≤α≤10°, for example, α can be 1°, 3°, 4°, 5°, 7°, 8°, 10°, etc.

[0097] When the downward tilt angle α of the two connecting rods 221 relative to the horizontal surface of the pot lid is too small, the connecting rods 221 and the driving member 21 tend to move upward along the height direction of the pot lid, affecting the limiting of the moving member 222 by the elastic member 24, making it impossible for the clamp assembly 2 to be stably maintained in the open state. When the downward tilt angle α of the two connecting rods 221 relative to the horizontal surface of the pot lid is too large, the user needs to apply more force to overcome the elastic force of the elastic member 24 to drive the driving member 21 to move upward until the clamp assembly 2 is in the clamping state. Moreover, when the tilt angle α is too large, the space occupied by the clamp assembly 2 in the height direction is too large, which can easily lead to the pot lid being too thick, resulting in a waste of space utilization. In the embodiment of this application, when 1°≤α≤10° is satisfied, the downward tilt angle α of the two connecting rods 221 relative to the horizontal surface of the pot lid is moderate, which can improve the stability of the clamp assembly 2 in the open state, while improving the user's operating convenience and the space utilization of the pot lid.

[0098] Preferably, the effect is better when the inclination angle α of the two connecting rods 221 relative to the horizontal plane is 1°≤α≤5°.

[0099] In one specific embodiment, such as Figures 8-10 As shown, the linkage mechanism 22 includes a first link 221a, a second link 221b, a first moving member 222a, and a second moving member 222b. The first link 221a is rotatably connected to the first moving member 222a and the driving member 21, and the second link 221b is rotatably connected to the second moving member 222b and the driving member 21.

[0100] In addition, such as Figure 8 As shown, the clamp assembly 2 includes two elastic members 24. The two ends of the elastic members 24 are connected to the first moving member 222a and the second moving member 222b respectively. Along the second direction Y, the first link 221a and the second link 221b are located between the two elastic members 24.

[0101] It should be noted that the first direction X and the second direction Y are both radial directions of the pot lid, and the first direction X and the second direction Y are perpendicular to each other.

[0102] In this embodiment, the elastic element 24 is disposed on the outside of the two connecting rods 221 along the second direction Y, providing sufficient movement space for the movement of the connecting rods 221. Furthermore, the two elastic elements 24 distributed along the second direction Y can also make the action of the elastic element 24 on the moving element 222 more stable and reliable.

[0103] In the above embodiments, as Figure 10 As shown, the drive member 21 has a first connecting part 212 extending along the height direction of the pot lid, and the connecting rod 221 is rotatably connected to the first connecting part 212.

[0104] In this embodiment, the first connecting portion 212 extends toward the linkage mechanism 22, thereby facilitating the rotational connection between the driving member 21 and the linkage mechanism 22. When the user presses the driving member 21, the first connecting portion 212 moves downward, thereby driving the linkage mechanism 22 to rotate. In addition, the first connecting portion 212 can protect the structure of the linkage 221, reducing impact damage to the linkage 221 from other components in the transportation environment or under accidental impact.

[0105] In the above embodiments, such as Figure 1 , Figures 10-12 As shown, the clamp assembly 2 may also include a base 25 having a guide groove 251 extending along the height direction of the pot lid, and a drive member 21 having a guide portion 211 extending radially outward therefrom, the guide portion 211 being slidable along the guide groove 251.

[0106] In this design, the base 25 provides structural protection for the drive component 21, reducing the risk of damage. The base 25 also facilitates the user's handling of the pot lid. Furthermore, the sliding fit between the guide portion 211 and the guide groove 251 improves the stability and reliability of the drive component 21's movement along the height direction, thereby enhancing the stability and reliability of the linkage mechanism 22's rotation. This, in turn, improves the reliability of the clamps 23 moving closer and further apart along the first direction X.

[0107] like Figures 5-6 As shown, the base 25 is detachably connected to the clamp assembly 2, meaning the base 25 is fixed relative to the lid 1, and the base 25 and the drive component 21 are located at the center of the lid. Figure 11 As shown, the base 25 has a base hole at its bottom that allows the drive member 21 to pass through. The drive member 21 can pass downward through the base hole along the height direction of the lid and connect to the connecting rod 221. In a specific embodiment, as... Figure 4 As shown, part of the base 25 is detachable, allowing the user to remove part of the base 25 to maintain and replace the drive component 21.

[0108] In other embodiments, such as Figure 2 As shown, the base 25 and guide 211 can also be omitted, and the user can directly switch the state of the clamp assembly 2 by operating the exposed drive component 21.

[0109] In the above embodiments, such as Figure 6 As shown, the clamp assembly 2 may further include a cover plate 26 for connection with the cover body 1, and a linkage mechanism 22 is installed between the cover plate 26 and the cover body 1. Figure 10and Figure 13 As shown, the cover plate 26 has a through hole 261 through which a portion of the linkage mechanism 22 and the first connecting portion 212 can pass. The cover plate 26 covers the linkage mechanism 22 and can be detachably connected to the base 25.

[0110] In this embodiment, the cover plate 26 protects the linkage mechanism 22, and the cover plate 26 has a through hole 261 to provide sufficient movement space for the drive member 21 and the linkage mechanism 22. When the clamp assembly 2 is in such a position... Figure 5 In the clamping state shown, the through hole 261 of the cover plate 26 allows the end of the connecting rod 221 connected to the drive member 21 to pass through, allowing a portion of the connecting rod 221 to extend above the cover plate 26, thereby reducing the overall thickness of the lid. When the clamping assembly 2 is in the position shown... Figure 6 When in the open state, the through hole 261 of the cover plate 26 allows the first connecting part 212 of the drive member 21 to pass through, so that the first connecting part 212 can extend between the cover plate 26 and the cover body 1, thereby driving the linkage mechanism 22 to move.

[0111] In the above embodiments, such as Figure 14 As shown, the clamp assembly 2 may also include a retainer 27. (As shown) Figure 3 As shown, the fixing member 27 is connected to the moving member 222 and the cover plate 26 by fasteners 3. Figure 8 or Figure 9 The moving part 222 shown has a clearance hole 2221 for avoiding the fastener 3.

[0112] In this embodiment, the fixing member 27 and the cover plate 26 are fixedly connected by the fastener 3, and the moving member 222 is clamped between the fixing member 27 and the cover plate 26. This connects the clamp 23, the moving member 222, the connecting rod 221, the elastic member 24, the fixing member 27, and the cover plate 26 into a clamp assembly 2. The clamp assembly 2 can be installed as a whole on the lid body 1 of the pot lid. During installation, the cover plate 26 and the lid body 1 can be connected by the fastener 3. Installing the clamp assembly 2 as a whole on the lid body 1 has the advantage of convenient installation and can reduce the decrease in installation accuracy caused by the accumulation of tolerances when each component is installed separately on the lid body 1. Furthermore, the clearance hole 2221 provided in the moving member 222 can avoid the fastener 3 when the moving member 222 moves along the first direction X, preventing the fastener 3 from obstructing the movement of the moving member 222 along the first direction X, allowing the clamp assembly 2 to be in a clamped or open state.

[0113] In the above embodiments, such as Figure 8 and Figure 9As shown, the moving part 222 includes a main body 2222 and a second connecting part 2223. Along the first direction X, the second connecting part 2223 is connected to the clamp 23, and the main body 2222 is used to connect to the linkage mechanism 22. The second connecting part 2223 is inclined downward relative to the main body 2222.

[0114] In this embodiment, as Figure 5 and Figure 6 As shown, the downwardly inclined second connecting part 2223 enables the moving part 222 to connect with the clamp 23, allowing the clamp 23 to extend downward, thereby providing space for the clamp 23 to clamp the pot body, which is beneficial for the pot lid to better cover the pot body.

[0115] In the above embodiments, such as Figure 3 and Figure 13 As shown, the cover plate 26 also includes a first limiting part 262, which improves the connection stability between the moving part 222 and the cover plate 26 and the fixing part 27.

[0116] like Figure 2 and Figure 14 As shown, the fixing member 27 includes a second limiting part 271, which is used to improve the connection stability between the moving member 222 and the fixing member 27.

[0117] like Figure 3 As shown, the moving part 222 is also provided with a groove at one end near the driving part 21 to avoid the movement of the connecting rod 221, providing sufficient movement space for the connecting rod 221.

[0118] In this embodiment, when the cookware is specifically a pressure cooker, a pressure limiting valve can be installed on the mounting cover 1, or a check valve can be installed on the clamp assembly 2.

[0119] The above descriptions are merely specific implementations of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
