Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a cooking utensil. Background Art

[0002] In related technologies, the lid of a pressure cooking appliance is generally provided with cover teeth, which can achieve pressure bearing during cooking by aligning the cover teeth with the pot teeth on the pot body assembly, and can achieve opening and closing of the lid assembly by staggering the cover teeth with the pot teeth on the pot body assembly.

[0003] To switch the position of the cover teeth on the lid assembly, a lid opening handle is typically provided on the lid assembly. The user rotates the lid opening handle to switch the position of the cover teeth. However, since the lid opening handle occupies a significant amount of space above the lid assembly, the user interface can only be placed on the pot body in order to accommodate a larger interface. This makes it difficult for the user to view and operate the interface. Utility Model Content

[0004] The main purpose of the present invention is to provide a cooking utensil to solve the problem in the related art that the interactive interface is set on the pot body, which makes it inconvenient for users to view and operate.

[0005] To achieve the above-mentioned object, the present invention provides a cooking utensil, comprising: a pot body assembly having pot teeth; a cover assembly openably and closably disposed on the pot body assembly, the cover assembly including a movably disposed locking member, the locking member being provided with a cover tooth, the locking member having a locking position in which the cover tooth is opposite to the pot teeth and a staggered position in which the cover tooth is staggered with the pot teeth; an operating portion movably disposed on the pot body assembly, the operating portion having a first operating position corresponding to the locking position and a second operating position corresponding to the staggered position; a transmission portion disposed between the operating portion and the locking member, the operating portion being capable of driving the locking member to switch between the staggered position and the locking position via the transmission portion; and a reset member disposed on the pot body assembly, wherein the reset member is capable of applying a reset force to the operating portion or the transmission member so that the operating portion remains in the second operating position when the cover assembly is not disposed on the pot body assembly; the reset force of the reset member being less than a switching force of the locking member from the locking position to the staggered position, so that the operating portion can remain in the first operating position when the cover assembly is disposed on the pot body assembly.

[0006] According to the technical solution of the present invention, the pot body assembly has pot teeth, and the lid body assembly includes a locking member, on which the lid teeth are provided. When the locking member moves, the lid teeth are driven to switch between a position opposite to the pot teeth and a position offset from the pot teeth. The cooking utensil also includes an operating portion and a transmission portion provided between the operating portion and the locking member. The user can operate the operating portion provided on the pot body assembly and drive the locking member to switch positions via the transmission portion. In other words, the operating portion for the user to operate to drive the locking member to switch positions is provided on the pot body assembly, thereby allowing the entire area above the lid body assembly to be freed up for the provision of a larger interactive interface, making it easier for the user to view and operate. Therefore, the technical solution of the present application can effectively solve the problem in the related art of providing the interactive interface on the pot body, which makes it inconvenient for the user to view and operate.

[0007] Furthermore, the pot body assembly is provided with a mounting opening, the cooking appliance further includes a mounting seat disposed at the mounting opening, the operating portion is mounted on the mounting seat, and a reset member is disposed between the operating portion and the mounting seat. The reset member is disposed between the operating portion and the mounting seat and directly applies a reset force to the operating portion, thereby preventing the operating portion from moving out of the second operating position when the lid is open due to user error.

[0008] Furthermore, a mounting cavity is provided between the mounting seat and the operating portion, and the reset member is arranged in the mounting cavity. The reset member is arranged in the mounting cavity between the mounting seat and the operating portion, which can protect the reset member.

[0009] Furthermore, the operating unit includes an operating knob and a drive seat that are interconnected and can rotate synchronously. The operating knob is located outside the mounting seat, and the drive seat is located inside the mounting seat and cooperates with the transmission unit. The operating knob is located outside the mounting seat, making it convenient for the user to hold the operating knob for operation. The drive seat is located inside the mounting seat and can cooperate with the portion of the transmission unit located inside the pot body assembly.

[0010] Furthermore, a first mating rib is provided on the side of the drive base facing the mounting base, and a second mating rib is provided on the side of the mounting base facing the drive base. The reset member is located between the first and second mating ribs and applies a reset force to the first mating rib. When the operating portion is accidentally triggered and moves toward the first operating position, the reset member is compressed and accumulates a reset force. When the force of the accidental trigger disappears, the reset force acts on the first mating rib and drives the drive base and the operating knob to rotate, causing the operating portion to return to the second operating position.

[0011] Furthermore, the operating portion includes a connecting structure disposed between the operating knob and the drive seat and extending through the mounting seat. The reset element is a curved spring wound around the outside of the connecting structure. Using a curved spring as the reset element simplifies the reset element structure while allowing for efficient use of the space surrounding the connecting structure.

[0012] Furthermore, the drive base includes a drive disc and a drive rod. The drive rod is disposed on a side of the drive disc away from the mounting base and offset from the rotation axis of the drive disc. The transmission portion includes a transmission slide. The transmission slide is provided with a first drive slot. The drive rod extends through the first drive slot. When the operating knob and the drive base are rotated, the transmission slide is driven to move. Through the cooperation between the drive rod and the first drive slot, the rotation of the operating knob and the drive base is converted into the movement of the transmission slide.

[0013] Furthermore, the transmission unit includes a first rotating coupler, a second rotating coupler, and a transmission rocker. The first rotating coupler is disposed on the pot body assembly and engages with the transmission slide for driving. When the transmission slide moves, it drives the first rotating coupler to rotate. The second rotating coupler is disposed on the lid assembly and engages with the first rotating coupler for locking. Rotation of the first rotating coupler drives synchronous rotation of the second rotating coupler. The transmission rocker is disposed on the lid assembly and connected between the second rotating coupler and the locking element. Rotation of the second rotating coupler drives the transmission rocker to swing, thereby driving the locking element to switch between a locked position and a misaligned position. The arrangement of the transmission slide, first rotating coupler, second rotating coupler, and transmission rocker allows the driving force applied by a user to an operating portion on the pot body assembly to be transmitted to the locking element on the lid assembly. This allows the user-operated operating portion to be located on the pot body assembly to drive the locking element to switch positions. This leaves the entire upper portion of the lid assembly free for a larger interactive interface, making it easier for the user to view and operate the interface.

[0014] Furthermore, the lock assembly includes a lock cover and a lock post disposed on the lock cover, the cover teeth being disposed on the lock cover, a second drive slot being disposed on the transmission rocker arm, the lock post being inserted into the second drive slot, and the lock cover being driven to rotate by the lock post when the transmission rocker arm swings. The swinging of the transmission rocker arm can drive the lock cover to rotate by the lock post, thereby switching the lock assembly between the engaging position and the disengaging position.

[0015] Furthermore, the cooking utensil further includes a first hook disposed on the lid assembly and a second hook disposed on the pot assembly. The second hook is swingably disposed and has a locked position in which it engages with the first hook and an unlocked position in which it is separated from the first hook. The operating portion further has a third operating position, the second operating position being located between the first and third operating positions. When the operating portion moves from the second operating position to the third operating position, the second hook is driven to switch from the locked position to the unlocked position. By driving the second hook from the locked position to the unlocked position by the operating portion, the operating portion can both drive the lid teeth and the pot teeth to disengage and drive the second hook to disengage from the first hook. In other words, the user can switch between the two locking structures by simply operating the operating portion located on the pot assembly. The user does not need to operate different operating members on the lid assembly and the pot assembly to switch between the two structures, thereby facilitating user use.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0043] like Figures 1 to 3 As shown, the present application provides a cooking utensil. The embodiment of the cooking utensil of the present application includes: a pot body assembly 10, a cover body assembly 20, an operating part 30, a transmission part 40 and a reset part 50. The pot body assembly 10 has a pot tooth 11; the cover body assembly 20 is openably arranged on the pot body assembly 10, and the cover body assembly 20 includes a movably arranged locking part 21, and a cover tooth 211 is arranged on the locking part 21. The locking part 21 has a locking position where the cover tooth 211 is arranged relative to the pot tooth 11 and a staggered position where the cover tooth 211 is staggered with the pot tooth 11; the operating part 30 is movably arranged on the pot body assembly 10, and the operating part 30 has a first operating position corresponding to the locking position and a second operating position corresponding to the staggered position; the transmission part 40 is arranged between the operating part 30 and the locking part 211. 1, the operating part 30 can drive the locking part 21 to switch between the misaligned position and the locked position through the transmission part 40; the reset part 50 is provided on the pot body assembly 10, wherein the reset part 50 can apply a reset force to the operating part 30 or the transmission part 40, so that when the cover body assembly 20 is not covered on the pot body assembly 10, the operating part 30 remains in the second operating position; the reset force of the reset part 50 is less than the switching force of the locking part 21 from the locked position to the misaligned position, so that when the cover body assembly 20 is covered on the pot body assembly 10, the operating part 30 can remain in the first operating position.

[0044] Using the technical solution of this embodiment, the pot body assembly 10 includes a pot teeth 11, and the lid assembly 20 includes a locking member 21, which is provided with a cover tooth 211. When the locking member 21 moves, the cover tooth 211 switches between a position opposite the pot teeth 11 and a position offset from the pot teeth 11. The cooking appliance also includes an operating portion 30 and a transmission portion 40 disposed between the operating portion 30 and the locking member 21. A user operates the operating portion 30 disposed on the pot body assembly 10, and the transmission portion 40 drives the lock member 21 to switch positions. This achieves the placement of the operating portion 30, which is used by the user to switch the position of the lock member 21, on the pot body assembly 10. This leaves the entire upper portion of the lid assembly 20 free for a larger interactive interface, making it easier for the user to view and operate the appliance. Therefore, the technical solution of this embodiment effectively solves the problem of placing the interactive interface on the pot itself, which inconveniences the user in viewing and operating the appliance.

[0045] In addition, since the transmission part 40 is arranged between the locking part 21 located on the cover assembly 20 and the operating part 30 located on the pot body assembly 10, the transmission part 40 has a part located on the pot body assembly 10 (specifically, the transmission slide 41 and the first rotating coupling part 42 mentioned later) and a part located on the cover assembly 20 (specifically, the second rotating coupling part 43 and the transmission rocker 44 mentioned later). When the cover assembly 20 is covered on the pot body assembly 10, the two parts of the transmission part 40 are coupled to realize transmission. The two parts of the transmission part 40 may not be coupled or coupled incorrectly, resulting in the problem that the pot teeth 11 and the cover teeth 211 are not completely aligned after the user operates the operating part 30 to move the preset amount.

[0046] To solve this problem, a reset member 50 is provided on the pot body assembly 10, which can apply a reset force to the operating part 30 or the transmission part 40, so that the operating part 30 is maintained in the second operating position corresponding to the misaligned position of the locking member 21. Even if the user accidentally touches the operating part 30 and the state of the operating part 30 changes, when the force of the user's accidental triggering disappears, the operating part 30 will be reset and maintained in the second operating position under the action of the reset member 50, thereby ensuring the correct coupling between the two parts of the transmission part 40 when the lid is closed; the operating part 30 also has a first operating position corresponding to the engaging position of the locking member 21. The reset force of the reset member 50 is less than the switching force that drives the locking member 21 to switch from the engaging position to the misaligned position. Therefore, when the lid assembly 20 is closed on the pot body assembly 10 and the operating part 30 switches to the first operating position and drives the locking member 21 to switch to the engaging position, the operating part 30 will not move away from the first operating position under the action of the reset member 50, thereby allowing the locking member 21 to remain in the engaging position, so that the pressure cooking process can proceed smoothly.

[0047] like Figure 1 、 Figure 3 and Figure 8 As shown, the pot body assembly 10 is provided with a mounting opening 121. The cooking appliance further includes a mounting base 60 disposed at the mounting opening 121. The operating portion 30 is mounted on the mounting base 60, and a reset member 50 is disposed between the operating portion 30 and the mounting base 60. The operating portion 30 is mounted on the pot body assembly 10 via the mounting base 60. The reset member 50 is disposed between the operating portion 30 and the mounting base 60 and directly applies a reset force to the operating portion 30, thereby preventing the operating portion 30 from moving out of the second operating position when the lid is open due to user error.

[0048] like Figure 1 As shown, the pot body assembly 10 includes an outer shell 12, a bottom shell 13 arranged below the outer shell 12, a middle plate 14 arranged above the outer shell 12, and a pot body 15 arranged in the outer shell 12, the mounting port 121 is arranged on the outer shell 12, and the pot teeth 11 are arranged at the upper end of the pot body 15.

[0049] like Figures 3 to 5 as well as Figure 8 As shown, there is a mounting cavity 1 between the mounting seat 60 and the operating portion 30, and the reset member 50 is arranged in the mounting cavity 1. The reset member 50 is arranged in the mounting cavity 1 between the mounting seat 60 and the operating portion 30 to protect the reset member 50.

[0050] like Figure 1 、 Figures 3 to 5 as well as Figure 8 As shown, the operating unit 30 includes an operating knob 31 and a drive seat 32 that are interconnected and can rotate synchronously. The operating knob 31 is located outside the mounting seat 60, while the drive seat 32 is located inside the mounting seat 60 and cooperates with the transmission unit 40. The operating knob 31 is located outside the mounting seat 60, making it convenient for the user to grasp the operating knob 31 for operation. The drive seat 32 is located inside the mounting seat 60 and can cooperate with the portion of the transmission unit 40 located inside the pot body assembly 10. The installation cavity 1 is located between the mounting seat 60 and the drive seat 32 to fully utilize the space inside the pot body assembly 10.

[0051] Specifically, if Figure 4 、 Figure 5 and Figure 8 As shown, the mounting cavity 1 includes a first half cavity 101 arranged on the side of the drive seat 32 facing the mounting seat 60 and a second half cavity 102 on the side of the mounting seat 60 facing the drive seat 32. When the drive seat 32 is installed on the mounting seat 60, the first half cavity 101 and the second half cavity 102 are connected to form the mounting cavity 1.

[0052] like Figure 3 、 Figure 4 、 Figure 5 and Figure 8As shown, a first mating rib 321 is provided on the side of the drive seat 32 facing the mounting seat 60, and a second mating rib 61 is provided on the side of the mounting seat 60 facing the drive seat 32. The reset member 50 is located between the first mating rib 321 and the second mating rib 61 and applies a reset force to the first mating rib 321. The reset member 50 is located between the first mating rib 321 and the second mating rib 61 and abuts against both the first mating rib 321 and the second mating rib 61. When the operating portion 30 is accidentally triggered and moves toward the first operating position, the reset member 50 is compressed and accumulates a reset force. When the force of the accidental trigger disappears, the reset force acts on the first mating rib 321 and drives the drive seat 32 and the operating knob 31 to rotate, causing the operating portion 30 to return to the second operating position.

[0053] like Figures 3 to 8 As shown, the operating portion 30 further includes a connecting structure 33 disposed between the operating knob 31 and the drive seat 32 and extending through the mounting seat 60. The reset member 50 is an arc spring wound around the outside of the connecting structure 33. The connecting structure 33 extends through the mounting seat 60 and connects the operating knob 31 and the drive seat 32, allowing them to rotate synchronously. The use of an arc spring as the reset member 50 not only simplifies the structure of the reset member 50 but also effectively utilizes the space around the connecting structure 33.

[0054] like Figure 5 、 Figure 7 and Figure 8 As shown, the connection structure 33 includes an inserting tube 331 provided on the operating knob 31 and an inserting block 332 provided on the drive seat 32. The inserting tube 331 has an inserting groove 333 formed on its inner side. The inserting block 332 is inserted into the inserting groove 333 and engages with the inserting tube 331 to prevent rotation. A mounting tube 62 is provided in the middle of the mounting seat 60 for the connection structure 33 to pass through. The first half cavity 101 is an annular groove structure formed between the outer periphery of the inserting block 332 and the circumferential wall of the drive seat 32. The second half cavity 102 is an annular groove structure formed between the outer periphery of the installment tube 62 and the circumferential wall of the mounting seat 60. When the drive seat 32 is installed on the mounting seat 60, the first half cavity 101 and the second half cavity 102 are connected to form an annular mounting cavity 1. An arc spring is provided in the annular mounting cavity 1, and the two ends of the arc spring respectively abut the first mating rib 321 and the second mating rib 61.

[0055] Of course, in an embodiment not shown in the figures, the reset member is not limited to an arc spring, and a torsion spring or other structure may also be used as the reset member, as long as it can apply a reset force to the first mating rib.

[0056] like Figure 1 、 Figure 5 、 Figure 6 and Figure 9As shown, the drive base 32 includes a drive rotary disk 322 and a drive rod 323. The drive rod 323 is disposed on a side of the drive rotary disk 322 away from the mounting base 60 and offset from the rotation axis of the drive rotary disk 322. The transmission portion 40 includes a transmission slide 41. The transmission slide 41 is provided with a first drive slot 411. The drive rod 323 is inserted into the first drive slot 411. When the operating knob 31 and the drive base 32 rotate, the drive slide 41 is driven to move. The drive rod 323 is offset from the rotation axis of the drive rotary disk 322. When the drive rotary disk 322 rotates, the drive rod 323 is driven to move in an arc or circular trajectory. The drive rod 323 is inserted into the first drive slot 411. When the drive rod 323 moves in an arc or circular trajectory, it abuts against the groove wall of the first drive slot 411, thereby driving the transmission slide 41 to move in translation, thereby converting the rotational motion of the drive base 32 into the translational motion of the transmission slide 41.

[0057] like Figure 1 、 Figure 4 as well as Figures 9 to 12 As shown, the transmission part 40 also includes a first rotating coupling 42, a second rotating coupling 43 and a transmission rocker 44. The first rotating coupling 42 is arranged on the pot body assembly 10 and is driven by the transmission slide 41. When the transmission slide 41 moves, it drives the first rotating coupling 42 to rotate. The second rotating coupling 43 is arranged on the cover body assembly 20 and is stopped by the first rotating coupling 42. When the first rotating coupling 42 rotates, it drives the second rotating coupling 43 to rotate synchronously. The transmission rocker 44 is arranged on the cover body assembly 20 and is connected between the second rotating coupling 43 and the locking member 21. When the second rotating coupling 43 rotates, it drives the transmission rocker 44 to swing and thereby drives the locking member 21 to switch between the locking position and the misaligned position. The arrangement of the transmission slide 41, the first rotating coupling member 42, the second rotating coupling member 43 and the transmission rocker arm 44 enables the driving force applied by the user to the operating portion 30 located on the pot body assembly 10 to be transmitted to the locking member 21 on the cover body assembly 20, thereby realizing that the operating portion 30 for user operation is arranged on the pot body assembly 10 to drive the locking member 21 to switch positions, so that the upper part of the cover body assembly 20 can be completely left empty to set up a larger interactive interface, which is convenient for the user to view and operate.

[0058] like Figure 1 、 Figure 2 and Figure 12As shown, the lock component 21 includes a lock cover 212 and a lock post 213 disposed on the lock cover 212. The cover tooth 211 is disposed on the lock cover 212. The transmission rocker 44 is provided with a second drive slot 441. The lock post 213 is disposed in the second drive slot 441. When the transmission rocker 44 swings, the lock cover 212 is driven to rotate via the lock post 213. The lock cover 212 is rotatably disposed. The lock post 213 is disposed in the second drive slot 441 of the transmission rocker 44. When the transmission rocker 44 swings, the lock cover 212 is driven to rotate via the lock post 213, thereby switching the lock component 211 between the engaging position and the disengaging position.

[0059] like Figure 1 As shown, the cover assembly 20 further includes a face cover 22 and a lining cover 23 disposed below the face cover 22. The locking member 21 is disposed below the lining cover 23. A second rotary coupling member 43 is disposed through the lining cover 23. A transmission rocker 44 is disposed between the lining cover 23 and the face cover 22. The locking post 213 extends upward through the lining cover 23 into the second driving slot 441 to engage with the transmission rocker 44.

[0060] In this embodiment, the locking member 21 is rotatably arranged on the locking cover; of course, in an embodiment not shown in the figure, the locking member can also be a caliper structure that performs translational motion to switch between the locking position and the misaligned position.

[0061] like Figure 9 and Figure 10 As shown, the upper end of the transmission slide 41 is provided with a driving spur tooth 412. The first rotating coupling member 42 includes a first coupling post 421 and a first gear 422 that are connected in a non-rotatable manner. The first gear 422 meshes with the driving spur tooth 412. Through the cooperation between the first gear 422 and the driving spur tooth 412, the first gear 422 and the first coupling post 421 are driven to rotate when the transmission slide 41 moves. The transmission slide 41 is also provided with a guide groove 413. The guide post 144 provided on the middle plate 14 is inserted into the guide groove 413 to guide the movement of the transmission slide 41.

[0062] like Figure 1 、 Figure 4 、 Figure 10 and Figure 14As shown, the first rotating coupling member 42 includes a first coupling post 421 disposed above the middle plate 14 and engaging with a stopper of the middle plate 14, and a first gear 422 disposed below the middle plate 14 and engaging with a stopper of the middle plate 14. The second rotating coupling member 43 includes a second coupling post 431 disposed below the lining cover 23 and engaging with a stopper of the lining cover 23, and a second gear 432 disposed above the lining cover 23 and engaging with a stopper of the lining cover 23. The first coupling post 421 and the second coupling post 431 can be rotationally coupled to achieve synchronous rotation of the first rotating coupling member 42 and the second rotating coupling member 43. Specifically, the first coupling post 421 is provided with a coupling slot with an open upper end, and the lower end of the second coupling post 431 is provided with a coupling block that plugs into and engages with the coupling slot.

[0063] like Figure 1 、 Figure 4 and Figure 14 As shown, a first mounting hole 141 is provided on the middle plate 14 , and the first rotating coupling member 42 is passed through the first mounting hole 141 .

[0064] The coupling groove on the first coupling post 421 and the coupling block at the lower end of the second coupling post 431 have a unique mating state. Specifically, within a 360° range, when the first coupling post 421 is in a certain position, the second coupling post 431 can only mate with the first coupling post 421 at a specific angle within that range. When the second coupling post 431 is rotated to another position, it cannot be plugged into the first coupling post 421. In this embodiment, the operating portion 30 is maintained in the second operating position by the reset member 50. The operating portion 30, the transmission slide 41, and the first rotating coupling member 42 are sequentially driven and engaged, maintaining the first rotating coupling member 42 in a specific position, thereby defining the position of the first coupling post 421. When the cover assembly 20 is pressed down to close, the second coupling post 431 can only couple with the first coupling post 421 when it is in a specific position. The second rotating coupling member 43, the transmission rocker 44, and the locking member 21 sequentially drive and engage, further defining the position of the locking member 21.

[0065] like Figure 1 、 Figure 11 and Figure 12 As shown, the second rotating coupling 43 includes a second gear 432, and the transmission rocker 44 is provided with a driven arc tooth 442 that meshes with the second gear 432. A rotating hole 443 is provided at one end of the transmission rocker 44 away from the driven arc tooth 442. The mounting post on the lining cover 23 is passed through the rotating hole 443. Through the cooperation between the driven arc tooth 442 and the second gear 432, the second rotating coupling 43 is driven to drive the transmission rocker 44 to swing around the central axis of the rotating hole 443 when it rotates.

[0066] like Figure 2 and Figure 12 As shown, a second driving groove 441 is further provided on the transmission rocker arm 44, and the lock column 213 on the locking member 21 is inserted into the second driving groove 441. When the transmission rocker arm 44 swings, it drives the locking member 21 to rotate, thereby realizing the position switching of the locking member 21.

[0067] like Figure 1 、 Figure 3 and Figure 13 As shown, the cooking utensil further includes a first hook provided on the cover assembly 20 and a second hook 70 provided on the pot body assembly 10. The second hook 70 is swingably provided and has a locked position engaged with the first hook and an unlocked position separated from the first hook. The operating portion 30 also has a third operating position, which is located between the first operating position and the third operating position. When the operating portion 30 moves from the second operating position to the third operating position, it drives the second hook 70 to switch from the locked position to the unlocked position. The second hook 70 is capable of engaging with the first hook on the lid assembly 20. When closing the lid, the first and second hooks 70 are first engaged to overcome the force of the lid-opening torsion spring between the lid assembly 20 and the pot body assembly 10, and then the lid teeth 211 are aligned with the pot teeth 11. When opening the lid, the lid teeth 211 and pot teeth 11 are first offset, and then the first hook 70 is separated from the second hook 70. This effectively ensures smooth position switching of the lid teeth 211 during the lid opening and closing process. Furthermore, the operating portion 30 drives the second hook 70 from the locked position to the unlocked position, enabling the operating portion 30 to both disengage the lid teeth 211 from the pot teeth 11 and disengage the second hook 70 from the first hook. This allows the user to switch between the two locking mechanisms simply by operating the operating portion 30 on the pot body assembly 10, eliminating the need to operate separate operating elements on the lid assembly and the pot body assembly to switch between the two mechanisms, thus facilitating user convenience.

[0068] like Figure 4 and Figure 13 As shown, the second hook 70 includes a locking plate 71, a locking hook 72 disposed at the upper end of the locking plate 71, and two rotating shafts 73 disposed on either side of the locking plate 71. The two rotating shafts 73 are respectively disposed in two second mounting holes 143 on two mounting plates 142 on the middle plate 14, so that the locking plate 71 is swingably mounted on the middle plate 14. A driving inclined surface 711 is provided on the locking plate 71. When the driving rod 323 swings in an arc or circular trajectory, it abuts against the driving inclined surface 711, causing the locking plate 71 to swing, thereby switching the second hook 70 from a locked position to an unlocked position.

[0069] like Figure 1 、 Figure 9 and Figure 13As shown, an avoidance recess 712 is also provided on the snap-fit ​​plate 71, which is adjacent to and above the driving inclined surface 711; the first driving groove 411 on the transmission slide 41 includes a vertically extending driving groove section 4111 and an avoidance groove section 4112 located below the driving groove section 4111, wherein the driving groove section 4111 is provided corresponding to the avoidance recess 712 on the snap-fit ​​plate 71, and the avoidance groove section 4112 is provided corresponding to the driving inclined surface 711 on the snap-fit ​​plate 71. When the drive rod 323 is located in the drive slot section 4111 and rotates, the drive rod 323 abuts against the side wall of the drive slot section 4111 and drives the transmission slide 41 to move. The avoidance recess 712 avoids the drive rod 323, so that the drive rod 323 cannot drive the locking plate 71 to swing. When the drive rod 323 is located in the avoidance slot section 4112 and rotates, the avoidance slot section 4112 avoids the drive rod 323, so that the drive rod 323 cannot drive the transmission slide 41 to move. The drive rod 323 cooperates with the driving inclined surface 711 and pushes against the driving inclined surface 711, causing the locking plate 71 to swing around the axis of the rotating shaft 73, thereby achieving disengagement. The above arrangement enables the drive rod 323 to respectively drive the transmission slide 41 and the locking plate 71 to make corresponding movements.

[0070] like Figure 6 As shown, a pushing ball head 3231 is provided at the end of the driving rod 323 to reduce the friction between the driving rod 323 and the driving inclined surface 711 when the driving rod 323 pushes the driving inclined surface 711, so that the user can rotate the operating part 30 more smoothly.

[0071] Specifically, when the operating part 30 rotates between the first operating position and the second operating position, the operating part 30 can drive the transmission slide 41 to move, but cannot drive the locking plate 71 to swing; when the operating part 30 is in the second operating position, the driving rod 323 is arranged corresponding to the intersection position of the avoidance recess 712 and the driving inclined surface 711; when the operating part 30 rotates from the second operating position to the third operating position, the operating part 30 can drive the locking plate 71 to swing and thereby switch the second hook 70 from the locked position to the unlocked position, but cannot drive the transmission slide 41 to move.

[0072] In this embodiment, the second hook 70 also includes an elastic reset member (such as a torsion spring) arranged in the shell 12. The elastic reset member can apply a resisting force to the snap plate 71 to keep the second hook 70 in the locked position, so that the second hook 70 can automatically reset after the user no longer operates the operating part 30, and at the same time drive the operating part 30 to reset to the second operating position.

[0073] like Figure 13As shown, a guiding slope is provided on the locking hook 72. In the process of closing the cover body assembly 20 to the pot body assembly 10, the first hook on the cover body assembly 20 cooperates with the guiding slope and pushes the locking hook 72 outward to drive the locking plate 71 to swing, so that the second hook 70 switches from the locked position to the unlocked position. After the first hook passes over the locking hook 72, the second hook 70 switches from the unlocked position to the locked position under the action of the elastic reset member. The above structure realizes the automatic fastening between the first hook and the second hook 70 during the closing process. The user does not need to perform any operations other than pressing down the cover body assembly 20, which is convenient for the user.

[0074] When the cover assembly 20 is not mounted on the pot body assembly 10, the operating portion 30 is maintained in the second operating position by the combined action of the reset member 50 disposed between the mounting base 60 and the operating portion 30 and the elastic reset member of the second hook 70. If the user accidentally triggers the operating portion 30, causing it to move from the second operating position to the first operating position, once the force of the accidental triggering disappears, the reset member 50 will apply a reset force to the operating portion 30, causing it to return to the second operating position. If the user accidentally triggers the operating portion 30, causing it to move from the second operating position to the third operating position, once the force of the accidental triggering disappears, the elastic reset member will apply a reset force to the locking plate 71, and the locking plate 71 will drive the operating portion 30 back to the second operating position.

[0075] Specifically, if Figure 1 、 Figure 3 、 Figure 9 and Figure 13 As shown, the operating portion 30 rotates in a non-full circle, and the first operating position is when the operating portion 30 rotates along Figure 3 The third operating position is the limit position of the clockwise rotation of the operating portion 30. Figure 3The second operating position is the extreme position of counterclockwise rotation in the middle, and the second operating position is located between the first operating position and the second operating position. When the operating part 30 rotates from the first operating position to the second operating position, the operating part 30 drives the locking member 21 to switch from the locking position to the misaligned position through the transmission part 40, and the second hook 70 remains in the locked position; when the operating part 30 rotates from the second operating position to the third operating position, the operating part 30 drives the second hook 70 to switch from the locked position to the unlocked position, and the locking member 21 remains in the misaligned position. When the second hook 70 is completely disengaged from the first hook, the cover assembly 20 will automatically open under the action of the cover opening torsion spring, that is, the process of the operating part 30 rotating from the first operating position to the second operating position to the third operating position. The unlocking process of opening the cover by first disengaging the teeth and then releasing the buckle is realized; when the user completes the cover opening operation, the operating part 30 will be reset to the second operating position under the action of the elastic reset part and the locking plate 71; when closing the cover, the first hook and the second hook 70 can be automatically engaged in the process of pressing the cover body assembly 20 downward, and then the user rotates the operating part 30 to make the operating part 30 rotate from the second operating position to the first operating position, and the operating part 30 drives the locking part 21 to switch from the misaligned tooth position to the locking tooth position through the transmission part 40, and the second hook 70 remains in the locked position, thereby realizing the cover closing locking process of first engaging the second hook 70 and then aligning the teeth.
