Description

Technical Field

[0001] This invention relates to the field of small household appliance technology, and more specifically, to a cooking appliance. Background Technology

[0002] In related technologies, the fastening structure between the pot body assembly and the lid assembly is an important component of the cooking appliance, enabling the lid assembly to stably close onto the pot body assembly. Especially for pressure cooking appliances, the fastening structure and the locking structure between the pot teeth and the lid teeth can form a double lock, ensuring safety during the cooking process.

[0003] Specifically, the fastening structure may include a fixed fastener on the pot body assembly and a movable hook on the lid assembly. The movable hook can switch from a position engaged with the fixed fastener to a position disengaged from the fixed fastener under the action of the release drive structure. To ensure the reliability of the drive, the release drive structure is generally also located on the lid assembly, but this will occupy a large amount of space on the lid assembly and affect the arrangement of other structures on the lid assembly. Summary of the Invention

[0004] The main objective of this invention is to provide a cooking appliance that solves the problem that the unlocking drive structure in related technologies affects the arrangement of other structures on the lid assembly.

[0005] To achieve the above objectives, the present invention provides a cooking appliance, including a pot body assembly and a lid assembly closable on the pot body assembly, wherein the lid assembly includes: a lid body; a movable hook portion movably disposed on the lid body and having a hook-on position and an unhooked position; the pot body assembly includes: a shell; a fixed hook portion disposed on the shell, wherein when the movable hook portion is in the hook-on position, the movable hook portion hooks into the fixed hook portion, and when the movable hook portion is in the unhooked position, the movable hook portion is separated from the fixed hook portion; an operating member movably disposed on the shell and protruding outward from the shell; and a transmission swing member including a pivot portion pivotally connected to the shell and a drive portion drivingly engaged with the movable hook portion, the drive portion being capable of driving the movable hook portion to switch from the hook-on position to the unhooked position, the operating member drivingly engaged with the transmission swing member to drive the transmission swing member to swing, and the operating member being located between the pivot portion and the drive portion.

[0006] According to the technical solution of this invention, the lid assembly includes a movable hook portion movably disposed on the lid body, and the pot body assembly includes a fixed hook portion fixedly disposed on the shell. The movable hook portion can switch between a latching position and an unlatching position, so that the lid assembly can stably close to the pot body assembly or the lid assembly can open relative to the pot body assembly. The pot body assembly also includes an operating component and a transmission swing component. The transmission swing component is pivotally connected to the shell via a pivot portion. The operating component can drive the transmission swing component to swing. When the transmission swing component swings, the driving part makes an arc-shaped movement and can drive the movable hook portion to switch from the latching position to the unlatching position. By placing the transmission swing component used to drive the movable hook portion on the pot body assembly, this application reduces the space occupied inside the lid assembly, allowing other components to be better arranged on the lid assembly. Furthermore, the operating component for user operation is located between the pivot and the drive unit. The drive unit is positioned close to the cover assembly, and the operating component is positioned relative to the pivot unit and close to the cover assembly, making the operating position relatively close to the upper end of the pot body assembly, facilitating user operation. Moreover, the aforementioned positional relationship between the operating component, the pivot unit, and the drive unit amplifies the driving stroke applied by the user to the operating component; that is, a small movement of the operating component by the user can drive a larger movement of the drive unit, further facilitating user operation. Therefore, the technical solution of this application effectively solves the problem in related technologies where the unlocking drive structure affects the arrangement of other structures on the cover assembly.

[0007] Furthermore, the cooker body assembly also includes a first reset member disposed within the housing. The first reset member applies a first reset force to the transmission rocker to keep the transmission rocker in a state of disengagement from the driving engagement of the movable hook. The first reset member ensures that the transmission rocker resets itself to a position where it does not drive the movable hook when no external force is applied, allowing the movable hook to smoothly reach the hook position.

[0008] Furthermore, the lower end of the movable hook is provided with a downwardly extending mating part. When the transmission swing member swings, the drive part pushes against the mating part to switch the movable hook from the hook position to the unhooked position. The mating part extends downward and has a certain vertical dimension, so that the drive part can always maintain the state of abutting against the mating part when it makes an arc-shaped movement, ensuring the reliability of the drive part driving the movable hook.

[0009] Furthermore, a pushing convex arc surface is provided on the side of the drive unit facing the mating part. The provision of the pushing convex arc surface can reduce the friction between the drive unit and the mating part, reduce the wear of the drive unit and the mating part, and at the same time make their relative movement smoother.

[0010] Furthermore, the operating component includes a button portion movably disposed within the housing and a second reset component disposed between the housing and the button portion. The second reset component applies a second reset force to the button portion to keep the button portion in a state of disengagement from the drive mechanism. The operating component is a press-type structure for user convenience; the second reset component allows the button portion to return to its initial position when the user stops pressing it, facilitating the user's next pressing operation.

[0011] Furthermore, a fixed hook is located at the upper end of the housing, and the housing has a corresponding communication port. The driving part extends upward through the communication port to engage with the movable hook. The communication port allows the driving part to extend through the housing and engage with the movable hook, thereby driving the movable hook.

[0012] Furthermore, the fixed hook includes a connecting plate and a hook body disposed above the connecting plate. The hook body is connected to the outer end plate of the connecting plate and extends inward. The connecting plate has an inner opening for the movable hook to extend into. The connecting plate surrounds the lower part of the hook body and connects between the hook body and the housing. This serves two purposes: firstly, it prevents the user from seeing the communication opening, and secondly, it prevents soup, food residue, etc., from flowing into the communication opening and entering the interior of the housing through it. The inner opening allows the movable hook to extend under the hook body to engage with it.

[0013] Furthermore, the movable hook is movably mounted on the cover body to switch between a hooked position and an unhooked position. Designating the movable hook as a moving part offers advantages such as simple structure and ease of movement control.

[0014] Furthermore, the cover assembly also includes a guide seat disposed on the cover body, with the movable hook engaging with the guide seat. The guide seat guides the movement of the movable hook, enabling it to move in a preset direction and ensuring the reliability of the hook's movement.

[0015] Furthermore, the cover assembly also includes a third resetting member disposed between the guide seat and the movable hook. The third resetting member applies a third resetting force to the movable hook to keep it in the hook position. The third resetting member ensures that the movable hook can be stably held in the hook position when no external force is applied, thereby ensuring that the cover assembly is stably placed on the pot body assembly.

[0016] Furthermore, the guide seat is movably mounted on the lid body, and the guide seat also includes a first hook portion extending downward from the lid body. The lid assembly also includes an inner pot lid detachably mounted below the lid body, and the inner pot lid is provided with a second hook portion that engages with the first hook portion. That is, the guide seat can be used to guide the movement of the movable hook portion and to fix and install the inner pot lid, realizing functional integration and simplifying the internal structure of the lid assembly.

[0017] Furthermore, the cookware body assembly also includes a first locking member disposed within the shell, and the lid assembly includes a second locking member and a drive plate disposed on the lid body. The second locking member is movably disposed and has a locking position that engages with the first locking member and an unlocking position that engages with the first locking member. The drive plate is movably disposed and can drive the second locking member to switch between the locking and unlocking positions. The movable hook engages with the drive plate. During the process of the movable hook switching from the hook position to the unlocking position, the movable hook drives the drive plate to move, thereby driving the second locking member to switch from the locking position to the unlocking position. The above configuration achieves simultaneous unlocking of the movable hook and the second locking member, and the user only needs to press the button during this process, making it convenient for the user to open the lid.

[0050] like Figure 1 , Figure 6 and Figure 7 As shown, this application provides a cooking appliance. An embodiment of the cooking appliance includes a pot body assembly 1 and a lid assembly 2 that is openable and closable on the pot body assembly 1. The lid assembly 2 includes a lid body 10 and a movable hook 20, which is movably disposed on the lid body 10 and has a hook-on position and an unhooked position. The pot body assembly 1 includes a housing 30, a fixed hook 40, an operating member 50, and a transmission swing member 60. The fixed hook 40 is disposed on the housing 30. When the movable hook 20 is in the hook-on position, the movable hook 20 engages with the fixed hook 40. The hook and latch engagement is such that when the movable hook 20 is in the unhooked position, the movable hook 20 separates from the fixed hook 40; the operating member 50 is movably mounted on the housing 30 and protrudes outward from the housing 30; the transmission swing member 60 includes a pivot part 61 pivotally connected to the housing 30 and a drive part 62 drivingly engaged with the movable hook 20. The drive part 62 can drive the movable hook 20 to switch from the hook and latch position to the unhooked position. The operating member 50 drives the transmission swing member 60 to swing. The operating member 50 is located between the pivot part 61 and the drive part 62.

[0051] Applying the technical solution of this embodiment, the lid assembly 2 includes a movable hook 20 movably disposed on the lid body 10, and the pot body assembly 1 includes a fixed hook 40 fixedly disposed on the housing 30. The movable hook 20 can switch between a hooked position and an unhooked position, so that the lid assembly 2 can stably close to the pot body assembly 1 or the lid assembly 2 can open relative to the pot body assembly 1. The pot body assembly 1 also includes an operating member 50 and a transmission swing member 60. The transmission swing member 60 is pivotally connected to the housing 30 via a pivot part 61. The operating member 50 can drive the transmission swing member 60 to swing. When the transmission swing member 60 swings, the driving part 62 makes an arc-shaped movement and can drive the movable hook 20 to switch from the hooked position to the unhooked position. By setting the transmission swing member 60 used to drive the movable hook 20 on the pot body assembly 1, this embodiment reduces the space occupied inside the lid assembly 2, allowing other components (such as a large operating panel on the lid assembly 2) to be better arranged. Furthermore, the operating component 50, which allows the user to operate the device, is located between the pivot portion 61 and the driving portion 62. The driving portion 62 is positioned close to the cover assembly 2, and the operating component 50 is positioned relative to the pivot portion 61 and close to the cover assembly 2. This arrangement ensures that the operating position is relatively close to the upper end of the pot body assembly 1, facilitating user operation. Moreover, the aforementioned positional relationship between the operating component 50, the pivot portion 61, and the driving portion 62 amplifies the driving stroke applied by the user to the operating component 50. In other words, a small movement of the operating component 50 by the user can drive a larger movement of the driving portion 62, further facilitating user operation. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where the unfastening driving structure affects the arrangement of other structures on the cover assembly.

[0052] Furthermore, in this embodiment, the movable hook 20 is driven by the swinging transmission component 60 to switch states, which has the advantages of simple structure and easy control, and can achieve reliable driving of the movable hook 20.

[0053] like Figure 1 and Figure 6 As shown, the cooker body assembly 1 also includes a first reset member 70 disposed within the housing 30. The first reset member 70 applies a first reset force to the transmission swing member 60 to keep the transmission swing member 60 in a state of disengagement from the movable hook 20. Here, "disengagement of the transmission swing member 60 from the movable hook 20" means that the transmission swing member 60 is not in contact with the movable hook 20 or is only in contact with the movable hook 20 but does not apply any force to it. The first reset member 70 allows the transmission swing member 60 to reset itself to a position where it does not drive the movable hook 20 when no external force is applied, allowing the movable hook 20 to smoothly reach the hook position.

[0054] like Figure 6 and Figure 7As shown, the transmission swing member 60 is provided with a first mounting recess 64, and the first reset member 70 is a spring structure with one end set in the first mounting recess 64 and the other end abutting against the middle plate 33 of the housing 30.

[0055] like Figure 1 , Figure 6 and Figure 10 As shown, the lower end of the movable hook 20 is provided with a downwardly extending mating part 21. When the transmission swing member 60 swings, the drive part 62 pushes against the mating part 21 to switch the movable hook 20 from the hook position to the unhooked position. The mating part 21 extends downward and has a certain vertical dimension. When the drive part 62 makes an arc-shaped movement (at this time, the drive part 62 will have displacement in the vertical direction), it can always maintain the state of abutting against the mating part 21, ensuring the reliability of the drive part 62 driving the movable hook 20.

[0056] Preferably, the driving part 62 is provided with a pushing convex arc surface 621 on the side facing the mating part 21. The provision of the pushing convex arc surface 621 can reduce the friction between the driving part 62 and the mating part 21, reduce the wear of the driving part 62 and the mating part 21, and at the same time make their relative movement smoother.

[0057] like Figure 7 As shown, the pivot portion 61 of the transmission swing member 60 includes two pivot shafts located at the bottom end of the transmission swing member 60 and on both sides of the transmission swing member 60. The housing 30 includes a middle plate 33 and a mounting bracket 36 located below the middle plate 33. A connecting post 331 is provided below the middle plate 33. The mounting bracket 36 is connected to the lower part of the middle plate 33 by fasteners passing through the mounting bracket 36 and the connecting post 331. The mounting bracket 36 is provided with mounting holes 361. The transmission swing member 60 is located in the mounting bracket 36, and the two pivot shafts are respectively inserted into the two mounting holes 361, so that the transmission swing member 60 can be swingably mounted on the mounting bracket 36.

[0058] like Figure 1 and Figure 6 As shown, the operating member 50 includes a button portion 51 movably disposed within the housing 30 and a second reset member 52 disposed between the housing 30 and the button portion 51. The second reset member 52 applies a second reset force to the button portion 51 to keep the button portion 51 in a state of disengagement from the transmission swing member 60. It should be noted that the above-mentioned "disengagement of the button portion 51 from the transmission swing member 60" means that the button portion 51 is not in contact with the transmission swing member 60 or that the button portion 51 is in contact with the transmission swing member 60 but does not apply force to the transmission swing member 60. The operating member 50 is a press-type structure for user convenience; the second reset member 52 enables the button portion 51 to return to its initial position when the user stops pressing it, facilitating the user's next pressing operation.

[0059] like Figure 1 As shown, the housing 30 also includes an outer shell 32 and a bottom shell 34. A middle plate 33 is connected above the outer shell 32, and the bottom shell 34 is connected below the outer shell 32. The outer shell 32 has a mounting opening 321, and the operating member 50 is mounted on the outer shell 32 via a mounting seat 35 located at the mounting opening 321. The button portion 51 is movably mounted on the mounting seat 35, and the second reset member 52 is a spring structure located between the mounting seat 35 and the button portion 51.

[0060] like Figure 2 , Figure 6 and Figure 9 As shown, the fixed hook 40 is disposed at the upper end of the housing 30, and the housing 30 is provided with a communication port 31 corresponding to the fixed hook 40. The driving part 62 extends upward through the communication port 31 to drive and cooperate with the movable hook 20. The provision of the communication port 31 allows the driving part 62 to extend through the housing 30 and cooperate with the movable hook 20, thereby realizing the driving of the movable hook 20.

[0061] like Figure 1 , Figure 2 and Figure 6 As shown, the fixed hook 40 includes a connecting plate 41 and a hook body 42 disposed above the connecting plate 41. The hook body 42 is connected to the outer end plate 411 of the connecting plate 41 and extends inward. The connecting plate 41 has an inner opening 412 for the movable hook 20 to extend into. The connecting plate 41 surrounds the lower part of the hook body 42 and connects between the hook body 42 and the housing 30. It can cover the communication port 31 located below the hook body 42, preventing the user from seeing the communication port 31 and preventing soup, food residue, etc. from flowing into the communication port 31 and entering the interior of the housing 30 through the communication port 31. The inner opening 412 allows the movable hook 20 to extend into the lower part of the hook body 42 to hook and engage with the hook body 42. The inner opening 412 is located inside the connecting plate 41. During use, the user will not easily see the inner opening 412, the drive unit 62, and the connecting port 31, ensuring the overall aesthetics of the pot body assembly and improving the user experience.

[0062] like Figure 6 and Figure 7 As shown, the transmission swing member 60 is also provided with a baffle plate 63 extending in the lateral direction. The baffle plate 63 is located below the communication port 31 and is used to shield the internal structure of the housing 30 to prevent food residues and other substances from entering the interior of the housing 30.

[0063] It should be noted that, as Figure 6 As shown, in this embodiment, the term "outer" refers to the side furthest from the vertical centerline of the cooking appliance (i.e., the side away from the cooking appliance's centerline). Figure 6The term "inside" (referring to the right side of the cooking utensil) refers to the side closest to the vertical center line of the cooking utensil (i.e., the side closest to the center line of the cooking utensil). Figure 6 (Left side of the middle).

[0064] like Figure 1 as well as Figures 4 to 6 As shown, the movable hook 20 is movably disposed on the cover body 10 to switch between a hooked position and an unhooked position. Designating the movable hook 20 as a movable component offers the advantages of simple structure and easy control of its movement.

[0065] like Figure 1 , Figure 4 , Figure 10 and Figure 11 As shown, the cover assembly 2 also includes a guide seat 80 disposed on the cover body 10, and the movable hook 20 is guided and engaged with the guide seat 80. The guide seat 80 can guide the movement of the movable hook 20, so that the movable hook 20 can move in a preset direction, ensuring the reliability of the movement of the movable hook 20.

[0066] like Figure 1 and Figure 6 As shown, the cover assembly 2 also includes a third reset member 90 disposed between the guide seat 80 and the movable hook 20. The third reset member 90 applies a third reset force to the movable hook 20 to keep the movable hook 20 in the hook position. The third reset member 90 ensures that the movable hook 20 can be stably held in the hook position when no external force is applied, thereby ensuring that the cover assembly 2 is stably placed on the pot body assembly 1.

[0067] like Figure 10 and Figure 11 As shown, the movable hook 20 includes a sliding plate portion 23 and a hook body portion 24 disposed at one end of the sliding plate portion 23. The hook body portion 24 extends downward from the cover body 10 to engage with the fixed hook portion 40. A mating portion 21 is disposed at the lower end of the hook body portion 24. The sliding plate portion 23 is slidably disposed on the guide seat 80. Specifically, the guide seat 80 includes a seat portion, on which a first groove 83 is provided. A guide protrusion 84 is provided within the first groove 83. The sliding plate portion 23 of the movable hook 20 is provided with a second groove 231. The sliding plate portion 23 is disposed within the first groove 83, and the guide protrusion 84 passes through the second groove 231, thereby achieving dual guidance between the guide seat 80 and the movable hook 20 and ensuring the reliability of the guidance.

[0068] like Figure 5 , Figure 10 and Figure 11As shown, the guide seat 80 is provided with a second mounting recess 85, the movable hook 20 is provided with a third mounting recess 22 opposite to the second mounting recess 85, and the third reset member 90 is a spring structure with its two ends respectively located in the second mounting recess 85 and the third mounting recess 22.

[0069] like Figure 1 , Figure 3 , Figure 6 and Figure 11 As shown, the guide seat 80 is movably mounted on the lid body 10. The guide seat 80 also includes a first hook portion 81 extending downward from the lid body 10. The lid assembly 2 also includes an inner pot lid 100 detachably mounted below the lid body 10. The inner pot lid 100 is provided with a second hook portion 101 that engages with the first hook portion 81. That is, the guide seat 80 can both guide the movement of the movable hook portion 20 and fix the inner pot lid 100, achieving functional integration and simplifying the internal structure of the lid assembly 2.

[0070] Specifically, such as Figure 6 and Figure 11 As shown, the guide seat 80 also includes a push top 82 extending downward and extending into the lid body 10. A first hook portion 81 is disposed on the inner side of the push top 82. When it is necessary to remove the inner pot lid 100, the user can move the push top 82 outward (i.e., towards the inner pot lid 100). Figure 6 (Move to the right) so that the guide seat 80 moves outward as a whole, and the first hook part 81 is no longer engaged with the second hook part 101. At this time, the inner pot lid 100 can be removed.

[0071] The movable hook 20 and the guide seat 80 guide each other. Specifically, when the lid assembly 2 and the pot body assembly 1 are unfastened, the guide seat 80 remains stationary under the action of the third reset member 90, and the movable hook 20 moves towards the pot body 1 under the driving action of the transmission swing member 60. Figure 6 The guide seat 80 guides the movement of the movable hook 20 when the inner pot lid 100 is moved to the left. When the inner pot lid 100 is disassembled, the movable hook 20 remains stationary under the action of the third reset member 90. The user pushes the top 82 to move the guide seat towards the left. Figure 6 The right side moves, and the movable hook 20 guides the movement of the guide seat 80.

[0072] like Figure 3 , Figure 6 and Figure 8As shown, at least one of the first hook portion 81 and the second hook portion 101 is provided with a guide slope, so that when installing the inner pot lid 100, simply pushing the inner pot lid 100 upwards will automatically engage the first hook portion 81 and the second hook portion 101, making it convenient for the user. Of course, the user can also manually push the top 82 to move the first hook portion 81 to a position that avoids the second hook portion 101. After the inner pot lid 100 is installed in place, the user can release the top 82, and the guide seat 80 will automatically move to the position where the first hook portion 81 and the second hook portion 101 are engaged under the action of the third reset member 90.

[0073] like Figure 1 and Figure 4 As shown, the cover body 10 includes a face cover 11 and a liner 12 disposed below the face cover 11. The main body of the movable hook 20, the main body of the guide seat 80, the third reset member 90, and the drive plate 130 are all disposed between the face cover 11 and the liner 12. The liner 12 has a clearance opening 121. The hook body 24 of the movable hook 20 and the push head 82 of the guide seat 80 extend downwards from the liner 12 through the clearance opening 121, and the hook body 24 and the push head 82 can move in the front-back direction (i.e.,...) within the clearance opening 121. Figure 6 The movement (left and right directions) within the text.

[0074] like Figure 12 As shown, the cover 12 also includes two first guide posts 122 disposed on both sides of the clearance opening 121. After the movable hook 20, guide seat 80 and third reset member 90 are assembled, they are installed together between the two first guide posts 122, and the movement of the movable hook 20 and guide seat 80 is guided by the two first guide posts 122. In addition, the cover 12 is also provided with a second guide post 123, which can pass through the groove on the guide protrusion 84 to guide the movement of the guide seat 80 and limit its extreme position.

[0075] The pot body assembly 1 also includes a first locking member 110 disposed within the housing 30, and the lid assembly 2 includes a second locking member 120 and a drive plate 130 disposed on the lid body 10. The second locking member 120 is movably disposed and has a locking position that engages with the first locking member 110 and an unlocking position that engages with the first locking member 110. The drive plate 130 is movably disposed and can drive the second locking member 120 to switch between the locking position and the unlocking position. The movable hook 20 engages with the drive plate 130. During the process of the movable hook 20 switching from the hook position to the unlock position, the movable hook 20 drives the drive plate 130 to move, thereby driving the second locking member 120 to switch from the locking position to the unlocking position. Through the locking engagement between the first locking member 110 and the second locking member 120 and the hook engagement between the movable hook 20 and the fixed hook 40, a double locking between the lid assembly 2 and the pot body assembly 1 can be achieved, ensuring that the lid assembly 2 is stably covered on the pot body assembly 1 during cooking. The movable hook 20 is driven to cooperate with the second locking member 120 through the drive plate 130. During the process of the movable hook 20 switching from the hook position to the unlock position, the movable hook 20 drives the drive plate 130 to move, thereby driving the second locking member 120 to switch from the locked position to the unlock position. This achieves the simultaneous unlocking of the movable hook 20 and the unlocking of the second locking member 120. During this process, the user only needs to press the button 51, which is convenient for the user to open the cover.

[0076] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the first locking member 110 is a pot tooth provided on the pot body, and the second locking member 120 is a cover tooth provided on the locking ring. The locking ring is rotatably installed below the liner 12. When the locking ring rotates, it drives the cover tooth to switch between a position aligned with the pot tooth (i.e., the locked position) and a position misaligned with the pot tooth (i.e., the unlocked position). Specifically, the drive plate 130 is movably disposed on the liner 12. The cover assembly 2 also includes a transmission swing arm 140 that drives and cooperates with the drive plate 130. The first end of the transmission swing arm 140 is provided with a transmission gear 141, and the side of the drive plate 130 is provided with a transmission rack that meshes with the transmission gear 141. The movement of the drive plate 130 causes the transmission swing arm 140 to swing through the meshing between the transmission rack and the transmission gear 141. The second end of the transmission swing arm 140 is provided with a linkage groove, and the lock ring is provided with a linkage column that extends upward through the liner and is inserted into the linkage groove. When the transmission swing arm 140 swings, the linkage column swings in an arc shape, thereby driving the lock ring to rotate.

[0077] When the lid is opened, the user presses the button 51, which drives the transmission swing member 60 along... Figure 6 The rotor swings counterclockwise, and the drive unit 62 on the transmission rotor 60 moves towards... Figure 6The left side of the movable hook 20 pushes upwards, and the movable hook 20 moves towards... Figure 4 and Figure 5 When the moving hook 20 moves to the left, it pushes the drive plate 130 towards the center. Figure 5 The left side moves, thereby driving the transmission swing arm 140 along... Figure 5 The transmission swing arm 140 rotates counterclockwise, and the locking ring rotates through the cooperation between the linkage groove and the linkage column, thereby moving the cover tooth from the position directly opposite the pot tooth to the position misaligned with the pot tooth.

[0078] When closing the lid, the user can directly press down on the lid assembly 2 to achieve automatic engagement between the movable hook 20 and the fixed hook 40 (at least one of the movable hook 20 and the fixed hook 40 is provided with a guide slope); after the hook engagement of the movable hook 20 and the fixed hook 40 is completed, the drive plate 130 moves under the action of the drive component (e.g., electric push rod or electromagnet, etc.) towards... Figure 5 The right side of the movement causes the transmission swing arm 140 to move along the path. Figure 5 The clockwise swing of the transmission arm 140 causes the locking ring to rotate through the cooperation between the linkage groove and the linkage column, thereby moving the cover tooth from a position misaligned with the pot tooth to a position directly opposite the pot tooth.

[0079] In this embodiment, the positions of the operating member 50, the pivot part 61, and the driving part 62 are such that the driving part 62 has sufficient driving stroke to drive the second locking member 120 to switch positions.

[0080] Furthermore, to avoid the teeth from being knocked out (if the latch is not completely disengaged, the cover assembly 2 will collide with the lid teeth under the action of the opening torsion spring), the first travel of the drive plate 130 driving the second locking member 120 from the locked position to the unlocked position is less than the travel of the movable hook 20 from the locked position to the unlocked position. This ensures that during the opening process, the lid teeth and the pot teeth can be misaligned first, and then the latch between the movable hook 20 and the fixed hook 40 can be unlocked.

[0081] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0082] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0083] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0084] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
