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] On one hand, embodiments of this application provide a pot lid, which includes a lid body, a clamp assembly, and a drive assembly.

[0005] The clamp assembly includes a linkage mechanism and at least two clamps, the clamps being movable relative to the cover, and the linkage mechanism being connected to at least two of the clamps.

[0006] The drive assembly includes a pressing member and a pushing member. The pressing member is used to connect with the linkage mechanism. The pressing member is capable of moving along a first direction, and the pushing member is capable of moving along a second direction. The first direction is perpendicular to the second direction.

[0007] During the movement of the pressing member along the first direction, the linkage mechanism can drive the clamps to move away from each other, so that the clamp assembly is in the open state. During the movement of the pushing member along the second direction, the pressing member can drive the pressing member to move along a third direction opposite to the first direction, so that the linkage mechanism can drive the clamps to move closer to each other, so that the clamp assembly is in the clamping state.

[0008] In this solution, the movement of the pressing component relative to the lid along a first direction drives the linkage mechanism to move the clamps away from each other, thus opening the clamp assembly. Conversely, the movement of the pushing component relative to the lid along a second direction drives the pressing component relative to the lid along a third direction, which in turn drives the linkage mechanism to move the clamps closer together, thus clamping the clamp assembly. Therefore, the user only needs to drive either the pressing component or the pushing component to open or close the clamp assembly, offering the advantage of convenient operation. Furthermore, since different structures (the pressing component and the pushing component) are operated separately during the opening or closing process, the risk of interference between components during opening or closing is reduced. The pressing component, after being directly or indirectly driven, moves along the first or third direction, transmitting the motion to the clamps through the linkage mechanism, causing the clamps to move radially along the lid. In other words, the linkage mechanism converts the vertical movement of the pressing component into radial reciprocating motion of the clamps, increasing the clamp's stroke within a smaller space. Moreover, the linkage mechanism that achieves this direction conversion not only has the advantage of simple structure but also facilitates control of the movement trajectory, thereby improving the reliability of the clamp's movement.

[0009] Optionally, the pushing member has a first guide surface, and the pressing member has a second guide surface. During the movement of the pushing member in the second direction, the first guide surface abuts against the second guide surface, so that the pressing member moves in the third direction.

[0010] Optionally, the first guide surface and the second guide surface are inclined surfaces or curved surfaces.

[0011] Optionally, the pressing member is provided with a first through hole, the pushing member can move along the second direction through the first through hole, and the second guide surface is provided on both sides of the first through hole.

[0012] Optionally, the clamp assembly includes a cover plate, and the drive assembly further includes a first elastic element, one end of which is connected to the pusher and the other end of which is connected to the cover plate.

[0013] Optionally, the pressing member further includes a connecting part, and the linkage mechanism includes at least two rods, one end of each of the at least two rods is rotatably connected to the connecting part, and the other end of each of the at least two rods is rotatably connected to at least two clamps respectively.

[0014] Optionally, the linkage mechanism further includes at least two moving parts, one end of which is fixedly connected to the clamp, and the other end of which is rotatably connected to the rod.

[0015] Optionally, the clamp assembly further includes a second elastic element, the two ends of which are respectively connected to the two moving elements, and the second elastic element is used to maintain the clamp assembly in the clamped state or the open state.

[0016] Optionally, the drive assembly further includes a timer, the pressing member having a receiving groove, at least a portion of the timer being located within the receiving groove, the timer having a first protrusion, and the sidewall of the receiving groove having a limiting groove, the first protrusion being located within the limiting groove.

[0017] On the other hand, this application provides a cookware, which includes a pot body and a pot lid, with the pot lid covering the opening of the pot body.

[0018] The pot lid is the pot lid described above.

[0019] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] This application provides a cookware, which includes a pot body and a lid, the lid of which can be closed to the opening of the pot body. The lid has clamps 22, which can clamp the lid and the pot body tightly when the lid is connected to the pot body.

[0068] 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.

[0069] The following description uses a pressure cooker as an example.

[0070] 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, a clamping assembly 2, and a driving assembly 3. The clamping assembly 2 includes a linkage mechanism 21 and at least two clamps 22, which are movable relative to the lid body 1. The linkage mechanism 21 is connected to the at least two clamps 22. The driving assembly 3 includes a pressing member 31 and a pushing member 32. The pressing member 31 is connected to the linkage mechanism 21 and is movable along a first direction 101. The pushing member 32 is movable along a second direction 102, where the first direction 101 and the second direction 102 are perpendicular.

[0071] During the movement of the pressing member 31 along the first direction 101, the linkage mechanism 21 can drive the clamps 22 to move away from each other, so that the clamp assembly 2 is in the open state. During the movement of the pushing member 32 along the second direction 102, the pressing member 31 can be driven to move along the third direction 103 opposite to the first direction 101, so that the linkage mechanism 21 can drive the clamps 22 to move closer to each other, so that the clamp assembly 2 is in the clamping state.

[0072] like Figure 1 As shown, the lid 1 is used to cover the opening of the pot body. The lid 1 is equipped with a sealing ring, which can form a seal between the lid and the pot body.

[0073] like Figure 4 As shown, when the pressing member 31 moves along the first direction 101, the pressing member 31 drives the linkage mechanism 21 to drive the clamps 22 to move away from each other. Each clamp 22 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; as shown Figure 5 and Figure 6 As shown, when the pusher 32 moves in the second direction 102, the pusher 32 drives the pressing member 31 to move in the third direction 103. The pressing member 31 drives the linkage mechanism 21 to drive the clamps 22 to move closer to each other. Each clamp 22 moves closer to the lid 1, and the clamp assembly 2 is in a clamping state, that is, the clamps 22 clamp the lid and the pot body, restricting the lid and the pot body from separating, so that the cooking space of the pot is sealed, and the pressure inside the pot can be increased, thereby improving the cooking efficiency.

[0074] Among them, such as Figure 4 and Figure 5 As shown, the first direction 101 and the third direction 103 are the height directions of the pot lid, as... Figure 2 and Figure 6 In the illustrated embodiment, the second direction 102 can be the radial direction of the pot lid. In other embodiments, the second direction 102 can also be any direction in a plane perpendicular to the height direction of the pot lid.

[0075] In this embodiment, the movement of the pressing member 31 relative to the cover 1 along the first direction 101 drives the linkage mechanism 21 to drive the clamps 22 away from each other, thus putting the clamp assembly 2 in the open state. The movement of the pushing member 32 relative to the cover 1 along the second direction 102 drives the pressing member 31 relative to the cover 1 along the third direction 103, thus driving the linkage mechanism 21 to drive the clamps 22 closer together, thus putting the clamp assembly 2 in the clamping state. Therefore, the user only needs to drive the pressing member 31 or the pushing member 32 to open or close the clamp assembly 2, which has the advantage of convenient operation. Moreover, since different structures (the pressing member 31 and the pushing member 32) are operated separately during the opening or closing of the clamp assembly 2, the risk of interference between the components during the opening or closing process can be reduced. Furthermore, after the pressing member 31 is directly or indirectly driven, it moves along the first direction 101 or the third direction 103, and is transmitted to the clamp 22 through the linkage mechanism 21, causing the clamp 22 to move radially along the pot lid. That is, the linkage mechanism 21 can convert the movement of the pressing member 31 along the height direction into the reciprocating movement of the clamp 22 along the radial direction. It can increase the movement stroke of the clamp 22 in a small space. Moreover, the linkage mechanism 21 that realizes the conversion of the movement direction not only has the advantage of simple structure, but also facilitates the control of the movement trajectory, thereby improving the reliability of the movement of the clamp 22.

[0076] In some embodiments, such as Figures 6 to 8 As shown, the pusher 32 has a first guide surface 321 and the pressing member 31 has a second guide surface 311. During the movement of the pusher 32 along the second direction 102, the first guide surface 321 abuts against the second guide surface 311 so that the pressing member 31 moves along the third direction 103.

[0077] When the user wants to move the pot lid from Figure 4 Switching from on state to Figure 5 When the lid is in the clamped state, the pusher 32 is driven along the second direction 102, so that the first guide surface 321 and the second guide surface 311 come into contact. The pusher 32 drives the pressing member 31 to move along the third direction 103, thereby driving the clamps 22 to move closer to each other, so as to realize the change of the lid from the open state to the clamped state.

[0078] In this embodiment, the movement of the pusher 32 along the second direction 102 is converted into the movement of the presser 31 along the third direction 103 by the contact between the first guide surface 321 of the pusher 32 and the second guide surface 311 of the presser 31. That is, the power transmission is achieved through the relative sliding of the first guide surface 321 and the second guide surface 311, which simplifies the structure of the pot lid and makes it easy and convenient for users to operate. On the one hand, it improves the transmission accuracy and motion stability of the drive assembly 3. On the other hand, the cooperation between the first guide surface 321 and the second guide surface 311 can adapt to the needs of narrow spaces, reduce the volume of the pot lid, and facilitate cleaning and storage for users.

[0079] In some embodiments, such as Figure 7 and Figure 8 As shown, the first guide surface 321 and the second guide surface 311 are inclined surfaces or curved surfaces.

[0080] In this embodiment, the first guide surface 321 and the second guide surface 311 are set as inclined surfaces, which can optimize the mechanical performance of the transmission between the pusher 32 and the pressing member 31, buffer the impact force when they collide to achieve the effect of saving effort, and improve the guiding accuracy and stability of the motion transmission between the pusher 32 and the pressing member 31.

[0081] In some other embodiments, at least one of the first guide surface 321 and the second guide surface 311 may also be an arc surface.

[0082] In some embodiments, such as Figure 7 As shown, the pressing member 31 is provided with a first through hole 312, and the pushing member 32 can move along the second direction 102 through the first through hole 312. The second guide surface 311 is provided on both sides of the first through hole 312.

[0083] In this embodiment, the first through hole 312 provides movement space for the pusher 32 to move along the second direction 102, so that the pusher 32 can pass through the first through hole 312.

[0084] like Figure 7 As shown, the second guide surface 311 is located on both sides of the first through hole 312, which enables the first guide surface 321 and the second guide surface 311 to accurately and stably abut against each other during the movement of the pusher 32 along the second direction 102, simplifying the structure of the pressing member 31.

[0085] In the above embodiments, such as Figure 6 , Figure 8 and Figure 10 As shown, the clamp assembly 2 includes a cover plate 23, and the drive assembly 3 also includes a first elastic member 33. One end of the first elastic member 33 is connected to the pusher 32, and the other end is connected to the cover plate 23.

[0086] Specifically, the cover plate 23 is slidably connected to the pusher 32, and the cover plate 23 and the cover body 1 remain relatively stationary. The cover plate 23 has a groove 231 for accommodating the movement of the pusher 32, and the end of the groove 231 has a limiting part 232 for abutting against the first elastic member 33.

[0087] The pusher 32 can also move along the fourth direction 104, which is the opposite direction to the second direction 102.

[0088] refer to Figure 6As shown, when the user applies a certain force to the pusher 32 in its initial state and moves it along the second direction 102, the pusher 32 moves along the slide groove 231 and approaches the limiting part 232 of the cover plate 23. The pusher 32 and the limiting part 232 compress the first elastic member 33. At the same time, the pusher 32 drives the pressing member 31 to move along the third direction 103. The pressing member 31 drives the rods 211 to move closer to each other, causing at least two clamps 22 to move closer to each other. This causes the pot lid to... Figure 4 Switching to the on state Figure 5 The clamping state is achieved when the user releases the force applied to the pusher 32. Under the rebound force of the first elastic member 33, the pusher 32 is driven to move along the fourth direction 104. The pusher 32 moves along the slide groove 231 and away from the limiting part 232 of the cover plate 23. At the same time, during the movement of the pusher 32 along the fourth direction 104, the first guide surface 321 and the second guide surface 311 no longer come into contact, and the pressing member 31 remains in a fixed position under the support of the rod 211, so that the clamping assembly 2 can be stably maintained in the clamping state.

[0089] In this embodiment, the cover plate 23 is used to protect the clamp assembly 2 and the drive assembly 3. The first elastic member 33 enables the push member 32 to automatically reset, simplifying the operation steps and further improving the user experience.

[0090] In some embodiments, a second protrusion 233 is fixedly connected to the bottom wall of the slide groove 231, and the pusher 32 has a limiting hole 322 for accommodating the second protrusion 233. The second protrusion 233 can slide along the limiting hole 322. When the pusher 32 moves along the fourth direction 104 under the action of the rebound force of the first elastic member 33, it can abut against the second protrusion 233 to limit the continued movement of the pusher 32 along the fourth direction 104 and prevent the pusher 32 from disengaging from the slide groove 231.

[0091] In the above embodiments, such as Figure 5 and Figure 7 As shown, the pressing member 31 also includes a connecting part 313, and the linkage mechanism 21 includes at least two rods 211. One end of each of the at least two rods 211 is rotatably connected to the connecting part 313, and the other end of each of the at least two rods 211 is rotatably connected to at least two clamps 22.

[0092] The connecting part 313 of the pressing member 31 is rotatably connected to the two rods 211. When the pressing member 31 moves along the first direction 101 or the third direction 103, it can drive the two rods 211 to rotate in the vertical plane, thereby driving the clamps 22 to move away from or closer to each other. The rods 211 are rotatably connected to the pressing member 31 and the clamps 22 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 pressing member 31 and the clamps 22, reduce the risk of fatigue fracture of the rods 211, and improve the service life of the pot lid.

[0093] At least one end of each of the two rods 211 can be rotatably connected to the connecting part 313 of the pressing member 31 via a pivot, and the other end of each of the two rods 211 can be rotatably connected to at least two clamps 22 via a pivot.

[0094] In other embodiments, the connection between the rod 211 and the pressing member 31 and / or the clamp 22 can also be a ball bearing, bolt connection, etc. This application does not limit the specific connection method between the rod 211 and the pressing member 31 and / or the clamp 22.

[0095] In the above embodiments, such as Figure 2 As shown, the linkage mechanism 21 also includes at least two moving parts 212. One end of the moving part 212 is fixedly connected to the clamp 22, and the other end of the moving part 212 is rotatably connected to the rod body 211.

[0096] At least two moving parts 212 are distributed along the movement direction of the clamp 22, and the movement direction of the moving parts 212 is consistent with the movement direction of the clamp 22. The moving parts 212 are driven by the rod 211, thereby realizing the indirect rotational connection between the rod 211 and the clamp 22. In this embodiment, when the rod 211 and the clamp 22 are indirectly rotatedly connected through the moving parts 212, it is not necessary to increase the volume of the rod 211 and the clamp 22, so that the rod 211 and the clamp 22 do not occupy too much space, thereby reducing the volume of the clamp assembly 2 and the pot lid.

[0097] Specifically, the moving part 212 can be a plate structure. In other embodiments, the moving part 212 can also be a columnar structure, a strip structure, etc. This application does not limit the specific structure of the moving part 212.

[0098] In the above embodiments, such as Figure 2 As shown, the clamp assembly 2 also includes a second elastic member 24, the two ends of which are respectively connected to two moving members 212. The second elastic member 24 is used to maintain the clamp assembly 2 in a clamped state or an open state.

[0099] like Figure 4 and Figure 5As shown, at least two second elastic elements 24 are connected between two moving elements 212. The two rods 211 and the second elastic elements 24 form an approximately triangular structure, that is, the ends of the two rods 211 near the pressing element 31 form the apex of the triangle, and the other ends of the two rods 211 and the second elastic elements 24 form the base of the triangle.

[0100] When the clamp assembly 2 switches from the clamping state to the open state, the pressing member 31 drives the rod 211 along the first direction 101, and the two moving parts 212 move away from each other. At this time, the second elastic member 24 remains in the stretched state. Under the action of the second elastic member 24, the two rods 211 and the connecting part 313 are subjected to a force along the first direction 101, thereby restricting the upward movement of the rods 211. At this time, the forces on the two rods 211 are balanced, and the clamp 22 remains in the open state, which improves the reliability and stability of the clamp assembly 2 in the open state.

[0101] When the clamp assembly 2 switches from the open state to the clamping state, the pressing member 31 drives the rod 211 along the third direction 103. At this time, the pressure on the second elastic member 24 disappears, and the two rods 211 and the connecting part 313 are subjected to the force along the third direction 103. Under the action of the rebound force of the second elastic member 24, the rod 211 rotates back to the position when it is clamped, the two moving parts 212 move closer to each other, and the clamp assembly 2 automatically returns to the clamping state. Moreover, the second elastic member 24 can automatically reset if the push member 32 is accidentally touched by a small amount. That is, the second elastic member 24 can prevent the pressing member 31 from accidentally opening the clamp 22 through the linkage mechanism 21 due to the user accidentally touching the push member 32, thereby improving the reliability and stability of the clamp assembly 2 in the clamping state.

[0102] Specifically, the second elastic element 24 can be a tension spring. In other embodiments, the second elastic element 24 can also be other structures. This application does not limit the specific structure of the second elastic element 24.

[0103] In some embodiments, such as Figure 4 and Figure 5 As shown, the drive assembly 3 may further include a timer 34, the pressing member 31 having a receiving groove 314, at least a portion of the timer 34 being located within the receiving groove 314, and the timer 34 having a first protrusion 341, such as Figure 7 As shown, the side wall of the receiving groove 314 has a limiting groove 315, and the first protrusion 341 is located in the limiting groove 315.

[0104] In this embodiment, when the user presses the timer 34, the first protrusion 341 of the timer 34 abuts against the bottom wall of the receiving groove 314, thereby driving the pressing member 31 to move along the first direction 101 through the timer 34. The limiting groove 315 and the first protrusion 341 can improve the connection stability between the timer 34 and the pressing member 31. Setting the timer 34 can remind the user of timed events, ignition shutdown, and overpressure alarm functions.

[0105] In some embodiments, such as Figure 2 As shown, the clamp assembly 2 also includes a fixing member 25, which is used to fix the moving member 212 between the cover plate 23 and the fixing member 25. The cover plate 23 and the fixing member 25 are connected by fasteners, which improves the connection reliability of the clamp assembly 2.

[0106] In addition, such as Figure 10 As shown, the cover plate 23 also includes a guide groove 234 and a second through hole 235. The guide groove 234 is used to accommodate the pressing member 31 and the timer 34. The pressing member 31 can move within the guide groove 234 along a first direction 101 or a third direction 103. The second through hole 235 provides sufficient space for the connection between the rod 211 and the pressing member 31. A portion of the rod 211 and the connecting portion 313 can pass through the second through hole 235.

[0107] like Figures 4 to 6 As shown, the specific working principle of the pot lid in this embodiment is as follows:

[0108] When the pot lid is Figure 4 Switching to the on state Figure 5 When the lid is clamped, the user applies a certain force to the pusher 32, causing it to move along the second direction 102 within the slide groove 231. The first elastic member 33 is compressed, and the first guide surface 321 abuts against the second guide surface 311. The pusher 32 drives the pressing member 31 to move along the third direction 103. The connecting part 313 drives the rod 211 to move upward along the height direction of the lid. The pressure on the first elastic member 33 disappears, and under the action of the rebound force of the first elastic member 33, the two moving parts 212 move closer to each other, causing the clamps 22 to move closer to each other until the clamping state is achieved, and the lid can be maintained in the clamping state. When the user withdraws the force on the pusher 32, the pusher 32 automatically resets along the fourth direction 104 under the action of the rebound force of the first elastic member 33. The sliding fit between the second protrusion 233 and the limiting hole 322 can prevent the pusher 32 from disengaging from the slide groove 231 when it moves along the fourth direction 104.

[0109] When the pot lid is Figure 5 Switching to clamping state Figure 4When the device is in the open state, the user applies a certain force to the timer 34 along the first direction 101, causing the timer 34 to drive the pressing member 31 to move along the first direction 101. The connecting part 313 drives the rod 211 to move along the first direction 101. The ends of the rods 211 away from the connecting part 313 move away from each other, and the two moving parts 212 move away from each other, causing the clamps 22 to move away from each other. The clamp assembly 2 is in the open state. At this time, the second elastic member 24 is in the stretched state, and the forces between the two rods 211 are balanced. The clamp assembly 2 can stably maintain the open state.
