Description

Technical Field

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

[0002] In the related art, pressure cooking appliances generally meet the pressure requirements during the cooking process by interlocking the pot teeth and the cover teeth.

[0003] The cover teeth can be aligned with the pot teeth to achieve pressure-bearing cooking; the cover teeth can also be offset from the pot teeth to enable opening and closing of the cover assembly. To enable the position of the cover teeth to be switched, the cooking appliance is generally equipped with an operating member that the user can operate to drive the cover teeth to switch positions.

[0004] When the lid is open, the cover teeth generally remain offset from the pot teeth, allowing the lid assembly to smoothly move downward to complete the lid closing operation. However, when the lid is open, the user may accidentally touch the operating member, causing the cover teeth to move to a position where they at least partially overlap with the pot teeth. This will hinder the downward movement of the lid assembly when the user subsequently closes the lid, affecting user experience. Utility Model Content

[0005] The main purpose of the present invention is to provide a driving assembly and a cooking utensil having the same, so as to solve the problem in the related art that the user may mistakenly operate the operating member for driving the cover teeth to switch positions when the cover is open.

[0006] To achieve the above-mentioned objectives, according to one aspect of the present invention, a drive assembly is provided for cooperating with a pot body assembly and / or a cover body assembly, the drive assembly being capable of driving a locking member on the cover body assembly to switch between a locked position and an unlocked position, the drive assembly comprising: an operating member; a transmission member disposed between the operating member and the locking member, wherein when the operating member moves or rotates, the locking member is driven to switch between the locked position and the unlocked position via the transmission member; a self-locking member being movably disposed on the pot body assembly or on the cover body assembly in a vertical direction and having a limit position and a release position, the self-locking member comprising a locking portion and a trigger portion, when the cover body assembly is not covered on the pot body assembly, the self-locking member remains in the limit position, the trigger portion extends upward from the pot body assembly or downward from the cover body assembly, the locking portion locks the transmission member to restrict the movement of the transmission member, and when the cover body assembly is covered on the pot body assembly, the self-locking member remains in the release position, the trigger portion is pressed to retract the self-locking member, and the locking portion unlocks the transmission member, allowing the transmission member to move.

[0007] According to the technical solution of the present invention, the drive assembly includes an operating member and a transmission member. By operating the operating member, the user can drive the transmission member to move, and the transmission member can then drive the locking member to move between a locked position and an unlocked position. The drive assembly also includes a self-locking member capable of locking the transmission member. The self-locking member has a limit position and a release position. When the cover assembly is not placed on the pot assembly, the locking portion of the self-locking member locks the transmission member and restricts its movement. Because the operating member and the transmission member are driven together, when the transmission member is locked, the operating member is also locked, thereby preventing the user from accidentally touching the operating member. When the cover assembly is placed on the pot assembly, the locking portion of the self-locking member unlocks the transmission member, allowing both the transmission member and the operating member to move. The user can then drive the locking member to switch positions by operating the operating member. Therefore, the technical solution of the present application can effectively solve the problem in the related art that when the cover is open, the user may accidentally operate the operating member used to switch the cover teeth.

[0008] Furthermore, the drive assembly includes a retaining member that applies a resisting force to the self-locking member to maintain the self-locking member in the restricted position. When the lid assembly is opened, the self-locking member automatically switches from the released position to the restricted position under the resisting force of the retaining member, thereby ensuring that the opening and closing states of the lid assembly correspond to the position of the self-locking member, eliminating the need for additional user operation and facilitating user use.

[0009] Furthermore, the drive assembly further comprises a mounting member, the retaining member comprises a compression spring, the compression spring being arranged between the mounting member and the self-locking member and applying a resisting force to the self-locking member. The arrangement of the mounting member provides an installation basis for the self-locking member and the retaining member.

[0010] Furthermore, the operating member is disposed on the pot body assembly, and the transmission member includes a first transmission member disposed on the pot body assembly and a second transmission member disposed on the lid assembly. A self-locking member is disposed on the pot body assembly. When the self-locking member is in a limited position, a locking portion locks the first transmission member to restrict the movement of the first transmission member. Placing the operating member on the pot body assembly frees up space above the lid assembly for a larger operating panel or other structure, facilitating user use. The first transmission member and the second transmission member are disposed within the pot body assembly and the lid assembly, respectively, to transmit a driving force applied by the user to the pot body assembly to the lid assembly, thereby driving the locking member to switch positions.

[0011] Furthermore, the first transmission member includes a first transmission slide, which is provided with a lock post. The locking portion includes a lock hook, which has a lock slot opening upward. When the self-locking member is in the release position, the lock slot is located below the lock post. When the self-locking member is in the limit position, the lock post is located within the lock slot. The first transmission slide is limited or released by the cooperation between the lock hook and the lock post, which can move up and down, and has the advantage of a simple structure.

[0012] Furthermore, the operating member includes a first knob and a transmission rod. The first knob is exposed externally from the pot body assembly. The transmission rod is arranged offset from the centerline of the first knob and extends toward the interior of the pot body assembly. The first transmission slide is provided with a matching slot, and the transmission rod is inserted into the matching slot. The matching slot can avoid the movement component of the transmission rod along the extension direction of the matching slot. The movement component of the transmission rod along the width direction of the matching slot drives the first transmission slide to move with the transmission rod, thereby converting the rotation of the operating member into the movement of the first transmission slide.

[0013] Furthermore, the first transmission member further includes a first rotating coupling post extending vertically, projecting upward from the pot body assembly. A first lower driven tooth is disposed on the first rotating coupling post, and a first lower driving tooth is disposed on the first transmission slide, meshing with the first lower driven tooth. When the first transmission slide moves in the transverse direction, the first rotating coupling post is driven to rotate. And / or, the second transmission member includes a second rotating coupling post extending vertically and a first transmission rocker disposed above the second rotating coupling post. The second rotating coupling post extends downward from the lid body assembly. An upper driving tooth is disposed on the second rotating coupling post, and an upper driven tooth is disposed on the first transmission rocker, meshing with the upper driving tooth. When the second rotating coupling post rotates, the first transmission rocker is driven to swing, thereby switching the locking member between a locked position and an unlocked position. The movement of the first transmission slide is converted into rotation of the first rotating coupling post through the engagement between the first lower driving tooth and the first lower driven tooth. This arrangement has the advantages of a simple structure and reliable transmission. The second rotating coupling post can couple with the first rotating coupling post, achieving synchronous rotation of the second and first rotating coupling posts. The second rotating coupling column and the first transmission rocker are respectively provided with meshing upper driving teeth and upper driven teeth, so that the first transmission rocker is driven to swing by the second rotating coupling column, which has the advantages of simple structure and reliable transmission.

[0014] Furthermore, the first transmission member includes a second transmission slide, which is located above the pot body assembly. A locking hole is provided on the lower surface of the second transmission slide. The locking portion includes an upwardly extending locking rod. When the self-locking member is in the release position, the locking rod is located below the locking hole. When the self-locking member is in the limit position, the locking rod is inserted into the locking hole. The locking rod and the lock hole cooperate to limit or release the second transmission slide, thereby achieving the advantage of a simple structure.

[0015] Furthermore, the first transmission member includes a connecting plate disposed within the pot body assembly and connected to the second transmission slide, the connecting plate being provided with a second lower driven tooth, and the operating member includes a second knob, the second knob being provided with a second lower driving tooth that meshes with the second lower driven tooth. Rotation of the second knob drives the connecting plate and the second transmission slide to move. Alternatively, the second transmission member includes a third transmission slide disposed on the lid assembly and a second transmission rocker disposed above the third transmission slide. The third transmission slide extends downwardly from the lid assembly and moves synchronously with the second transmission slide. Movement of the third transmission slide drives the second transmission rocker to swing, thereby switching the locking member between a locked position and an unlocked position. The engagement between the second lower driving tooth and the second lower driven tooth converts rotation of the second knob into lateral movement of the connecting plate and the second transmission slide. Position switching of the locking member is achieved by the second transmission rocker being driven in connection with the third transmission slide and the locking member, thereby providing the advantage of a simple structure.

[0016] According to another aspect of the present invention, a cooking appliance is provided, comprising a pot assembly, a lid assembly that is openably and closably disposed over the pot assembly, and a drive assembly disposed between the pot assembly and the lid assembly. The drive assembly is the aforementioned drive assembly. The aforementioned drive assembly effectively addresses the related art issue of a user misoperating an operating member for shifting the cover teeth when the lid is open. Cooking appliances incorporating the aforementioned drive assembly also possess the aforementioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0044] The present application provides a driving assembly for cooperating with the pot body assembly 2 and / or the cover body assembly 1, the driving assembly being capable of driving the locking member 101 on the cover body assembly 1 to switch between a locked position and an unlocked position, wherein: Figures 1 to 4 shows a schematic structural diagram of a first embodiment of a drive assembly according to the present application; Figures 5 and 6 shows a structural schematic diagram of a second embodiment of a drive assembly according to the present application; Figures 7 to 10 A structural schematic diagram of a third embodiment of a drive assembly according to the present application is shown.

[0045] like Figures 1 to 4 As shown, the first embodiment of the drive assembly of the present application includes: an operating member 10 , a transmission member 20 and a self-locking member 30 . Among them, the transmission member 20 is arranged between the operating member 10 and the locking member 101. When the operating member 10 moves or rotates, the locking member 101 is driven by the transmission member 20 to switch between the locked position and the unlocked position; the self-locking member 30 is movably arranged on the pot body assembly 2 or on the cover body assembly 1 in the vertical direction and has a limit position and a release position. The self-locking member 30 includes a locking part 31 and a trigger part 32. When the cover body assembly 1 is not covered on the pot body assembly 2, the self-locking member 30 remains in the limit position, the trigger part 32 extends upward from the pot body assembly 2 or downward from the cover body assembly 1, and the locking part 31 locks the transmission member 20 to limit the movement of the transmission member 20. When the cover body assembly 1 is covered on the pot body assembly 2, the self-locking member 30 remains in the release position, the trigger part 32 is pressed to cause the self-locking member 30 to retract, and the locking part 31 unlocks the transmission member 20, so that the transmission member 20 can move.

[0046] Using the technical solution of this embodiment, the drive assembly includes an operating member 10 and a transmission member 20. By operating the operating member 10, a user can activate the transmission member 20, thereby driving the locking member 101 between a locked and unlocked position. The drive assembly also includes a self-locking member 30 capable of locking the transmission member 20. The self-locking member 30 has a limit position and a release position. When the cover assembly 1 is not placed on the pot assembly 2, the locking portion 31 of the self-locking member 30 locks the transmission member 20 and restricts its movement. Because the operating member 10 and the transmission member 20 are in driving engagement, when the transmission member 20 is locked, the operating member 10 is also locked, thereby preventing the user from accidentally touching the operating member. When the cover assembly 1 is placed on the pot assembly 2, the locking portion 31 of the self-locking member 30 unlocks the transmission member 20, allowing both the transmission member 20 and the operating member 10 to move. The user can then operate the operating member 10 to switch the locking member 101 between positions. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that the user may mistakenly operate the operating member for driving the cover teeth to switch positions when the cover is in the open state.

[0047] Specifically, in this embodiment, a cover tooth is provided on the locking member 101. The above-mentioned "locked position" refers to the position of the locking member 101 when the cover tooth is aligned with the pot tooth on the pot body assembly 2; the above-mentioned "unlocked position" refers to the position of the locking member 101 when the cover tooth is misaligned with the pot tooth on the pot body assembly 2.

[0048] Specifically, the operating member 10 can be disposed on the pot body assembly 2 or on the cover assembly 1. When the operating member 10 is disposed on the cover assembly 1, the transmission member 20 is also located within the cover assembly 1, and in this case, the self-locking member 30 is also disposed within the cover assembly 1. When the operating member 10 is disposed on the pot body assembly 2, part of the transmission member 20 is located within the pot body assembly 2, and another part of the transmission member 20 is located within the cover assembly 1, so that the driving force of the operating member 10 is transmitted from the pot body assembly 2 to the cover assembly 1 to drive the locking member 101 to switch positions. In this case, the self-locking member 30 can be disposed in either the cover assembly 1 or the pot body assembly 2, or the self-locking member 30 can be disposed in both the pot body assembly 2 and the cover assembly 1.

[0049] When the self-locking member 30 is arranged in the cover assembly 1, the trigger part 32 cooperates with the pot body assembly 2. When the cover assembly 1 is covered on the pot body assembly 2, the pot body assembly 2 presses upward against the trigger part 32, causing the self-locking member 30 to move upward as a whole and move from the limited position to the release position; when the self-locking member 30 is arranged on the pot body assembly 2, the trigger part 32 cooperates with the cover assembly 1. When the cover assembly 1 is covered on the pot body assembly 2, the cover assembly 1 presses downward against the trigger part 32, causing the self-locking member 30 to move downward as a whole and move from the limited position to the release position.

[0050] In this embodiment, the drive assembly further includes a retaining member 40, which applies a resisting force to the self-locking member 30 to maintain the self-locking member 30 in the restricted position. The retaining member 40 applies a resisting force to the self-locking member 30 to maintain the self-locking member 30 in the restricted position, so that when the cover assembly 1 is opened, the self-locking member 30 automatically switches from the released position to the restricted position under the action of the resisting force of the retaining member 40, thereby achieving a correspondence between the open and closed state of the cover assembly and the position of the self-locking member 30, without requiring the user to perform additional operations, and facilitating user use.

[0051] In this embodiment, the drive assembly further includes a mounting member 50, and the retaining member 40 includes a compression spring, which is disposed between the mounting member 50 and the self-locking member 30 and applies a resisting force to the self-locking member 30. The arrangement of the mounting member 50 provides a mounting base for the self-locking member 30 and the retaining member 40.

[0052] In this embodiment, the mounting member 50 extends to the bottom of the self-locking member 30 , and the two ends of the compression spring respectively press against the portion of the mounting member 50 below the self-locking member 30 and the self-locking member 30 to apply an upward pressing force to the self-locking member 30 .

[0053] like Figure 1 、 Figure 11 and Figure 12 As shown, in this embodiment, the operating member 10 is disposed on the pot body assembly 2. The transmission member 20 includes a first transmission member 21 disposed on the pot body assembly 2 and a second transmission member 22 disposed on the cover assembly 1. A self-locking member 30 is disposed on the pot body assembly 2. When the self-locking member 30 is in the limit position, the locking portion 31 locks the first transmission member 21 to restrict the movement of the first transmission member 21. Placing the operating member 10 on the pot body assembly 2 frees up space above the cover assembly 1 for a larger operating panel or other structure, making it more convenient for the user. The first transmission member 21 and the second transmission member 22 are disposed in the pot body assembly 2 and the cover assembly 1, respectively, to transmit the driving force applied by the user to the pot body assembly 2 to the cover assembly 1, thereby driving the locking member 101 to switch positions.

[0054] like Figure 1 and Figure 3As shown, the first transmission member 21 includes a first transmission slide 211, a lock column 2111 is provided on the first transmission slide 211, and the locking portion 31 includes a lock hook 311, and the lock hook 311 has a lock groove 312 opening upward. When the self-locking member 30 is in the release position, the lock groove 312 is located below the lock column 2111, and when the self-locking member 30 is in the limit position, the lock column 2111 is located in the lock groove 312. The lock hook 311 has a lock slot 312 opening upward, and the lock column 2111 is located in the lock slot 312 when the self-locking member 30 is in the limit position. The side wall of the lock slot 312 stops the lock column 2111, thereby limiting the movement of the first transmission slide 211 in the lateral direction. When the self-locking member 30 moves from the limit position to the release position, the self-locking member 30 moves downward as a whole, so that the lock hook 311 and the lock slot 312 also move downward, and the side wall of the lock slot 312 no longer stops the lock column 2111, so that the first transmission slide 211 can move in the lateral direction. The locking hook 311 and the lock column 2111 that can move up and down are cooperated to achieve the limitation or release of the first transmission slide 211, which has the advantage of simple structure.

[0055] like Figure 1 and Figure 2 As shown, the operating member 10 includes a first knob 11 and a transmission rod 12. The first knob 11 is exposed outward from the pot body assembly 2. The transmission rod 12 is offset from the centerline of the first knob 11 and extends toward the interior of the pot body assembly 2. A first transmission slide 211 is provided with a matching slot 2112, and the transmission rod 12 is inserted into the matching slot 2112. The transmission rod 12 is offset from the centerline of the first knob 11. When the user rotates the first knob 11, the transmission rod 12 moves in an arc or circular trajectory. The matching slot 2112 is provided on the first transmission slide 211. The matching slot 2112 can avoid the movement component of the transmission rod 12 along the extension direction of the matching slot 2112. The movement component of the transmission rod 12 along the width direction of the matching slot 2112 drives the first transmission slide 211 to move with the transmission rod 12, thereby converting the rotation of the operating member 10 into movement of the first transmission slide 211.

[0056] In this embodiment, the first knob 11 protrudes outward from the pot body assembly 2. Of course, the arrangement of the first knob 11 is not limited to this. For example, the first knob may not protrude outward from the pot body assembly, and an operating recess may be provided on the pot body assembly for the user to insert his hand to operate the first knob.

[0057] Specifically, in this embodiment, the matching long slot 2112 extends in the vertical direction, and when the first knob 11 rotates, the transmission rod 12 drives the first transmission slide plate 211 to move in the lateral direction.

[0058] like Figures 1 to 3As shown, the first transmission member 21 also includes a first rotating coupling post 212 extending vertically. The first rotating coupling post 212 extends upward from the pot body assembly 2. A first lower driven tooth 2121 is provided on the first rotating coupling post 212, and a first lower driving tooth 2113 is provided on the first transmission slide 211, which meshes with the first lower driven tooth 2121. When the first transmission slide 211 moves horizontally, it drives the first rotating coupling post 212 to rotate. The first lower driven tooth 2121 is a gear-like tooth structure, while the first lower driving tooth 2113 is a spur tooth structure. The cooperation between the first lower driving tooth 2113 and the first lower driven tooth 2121 converts the movement of the first transmission slide 211 into the rotation of the first rotating coupling post 212, resulting in a simple structure and reliable transmission. The first rotating coupling post 212 extends upward from the pot body assembly 2, facilitating the coupling between the first rotating coupling post 212 and the second transmission member 22 on the lid assembly 1.

[0059] like Figure 1 、 Figure 3 and Figure 4 As shown, the second transmission member 22 includes a second rotating coupling post 221 extending vertically and a first transmission rocker 222 disposed above the second rotating coupling post 221. The second rotating coupling post 221 extends downward from the cover assembly 1. The second rotating coupling post 221 is provided with an upper driving tooth 2211, and the first transmission rocker 222 is provided with an upper driven tooth 2221 that engages with the upper driving tooth 2211. When the second rotating coupling post 221 rotates, it causes the first transmission rocker 222 to swing, thereby driving the locking member 101 to switch between the locked and unlocked positions. The locking member 101 is driven by the first transmission rocker 222 to switch positions, which has the advantage of a simple structure. Specifically, the second rotating coupling post 221 can be coupled to the first rotating coupling post 212, achieving synchronous rotation of the second rotating coupling post 221 and the first rotating coupling post 212. The second rotating coupling column 221 and the first transmission rocker 222 are respectively provided with meshing upper driving teeth 2211 and upper driven teeth 2221, so that the first transmission rocker 222 can be driven to swing by the second rotating coupling column 221, which has the advantages of simple structure and reliable transmission.

[0060] Specifically, if Figure 3As shown, the first rotating coupling column 212 includes a lower gear 2122 and a lower coupling 2123 arranged above the lower gear 2122, the first lower driven tooth 2121 is arranged on the lower gear 2122, and the lower coupling 2123 is provided with a coupling groove; the second rotating coupling column 221 includes an upper gear 2212 and an upper coupling 2213 arranged below the upper gear 2212, the upper driving tooth 2211 is arranged on the upper gear 2212, and a coupling column is provided below the upper coupling 2213, and the coupling column can be inserted into the coupling groove to realize a non-rotating connection between the first rotating coupling column 212 and the second rotating coupling column 221, so that the second rotating coupling column 221 can rotate synchronously with the first rotating coupling column 212.

[0061] like Figure 4 As shown, the first transmission rocker 222 is also provided with a first rotating hole 2222 and a first transmission hole 2223, wherein when the second rotating coupling column 221 rotates, it drives the first transmission rocker 222 to swing about the axis of the first rotating hole 2222, and the transmission column 1012 on the locking component 101 is inserted into the first transmission hole 2223. When the first transmission rocker 222 swings, it drives the transmission column 1012 to swing through the first transmission hole 2223, thereby driving the locking component 101 to switch between the locked position and the unlocked position.

[0062] Specifically, in this embodiment, the locking member 101 is a locking cover, which includes a cover body 1011 and a transmission post 1012 disposed on the cover body 1011. When the first transmission rocker 222 swings, it drives the locking cover to rotate, thereby driving the cover teeth on the locking cover to switch between a position directly aligned with the pot teeth and a position offset from the pot teeth.

[0063] Of course, in an embodiment not shown in the figures, the locking member may also be a caliper structure.

[0064] Figure 5 and Figure 6 A structural diagram of a second embodiment of the drive assembly of the present application is shown. The following mainly describes the parts of the second embodiment that are different from the first embodiment, and the same parts of the two embodiments are not repeated.

[0065] The main difference between the two embodiments lies in the setting position and specific structure of the self-locking member 30. Specifically, in the first embodiment, the self-locking member 30 is set on the pot body assembly 2; in the second embodiment, the self-locking member 30 is set on the cover assembly 1.

[0066] In the first embodiment, the trigger portion 32 is located at the upper part and can extend upward from the pot body assembly 2 to cooperate with the cover body assembly 1, the locking portion 31 is located at the lower part and cooperates with the first transmission slide 211, and the retaining member is a compression spring arranged below the self-locking member 30 and presses upward against the self-locking member 30.

[0067] In the second embodiment, the trigger portion 32 is located at the lower part and can extend downward from the cover assembly 1 to cooperate with the pot body assembly 2, the locking portion 31 is located at the upper part and cooperates with the first transmission rocker 222, and the retaining member 40 is a compression spring arranged above the self-locking member 30 and presses downward against the self-locking member 30.

[0068] Specifically, if Figure 4 and Figure 6 As shown, the first transmission rocker 222 is provided with a locking hole 2224, and the locking portion 31 includes a locking block extending from top to bottom. When the cover assembly 1 is not placed on the pot assembly 2, the retaining member 40 presses downward against the self-locking member 30, causing the locking block to extend into the locking hole 2224, thereby restricting the first transmission rocker 222 from swinging. When the cover assembly 1 is placed on the pot assembly 2, the pot assembly 2 presses upward against the triggering portion 32, causing the self-locking member 30 to move upward as a whole, and the locking block to disengage the locking hole 2224 upward, allowing the first transmission rocker 222 to swing.

[0069] By setting the self-locking member 30 on the cover body assembly 1, the first transmission rocker 222 is locked in the open state, and then the locking member 101 is locked, so that the locking member 101 always maintains the position where the cover teeth and the pot teeth are offset, so that the cover teeth will not interfere with the pot teeth when the cover is closed next time, so that the cover body assembly 1 can move down smoothly.

[0070] like Figure 5 and Figure 6 As shown, the self-locking member 30 is provided with a mounting cylinder with an opening facing upward, and the retaining member 40 is provided in the mounting cylinder. The two ends of the retaining member 40 respectively abut the bottom wall of the mounting cylinder and the surface cover 103 to apply a downward abutting force to the self-locking member 30.

[0071] It should be noted that the self-locking member 30 in the first embodiment and the self-locking member 30 in the second embodiment can be used simultaneously, that is, the self-locking member 30 in the first embodiment can be set on the pot body assembly 2 and the self-locking member 30 in the second embodiment can be set on the cover assembly 1 at the same time.

[0072] Figures 7 to 10 A structural schematic diagram of a third embodiment of the drive assembly of the present application is shown. The operating member 10, the transmission member 20 and the self-locking member 30 in this embodiment are all different from those in the first embodiment.

[0073] Specifically, if Figure 7 and Figure 14As shown, the first transmission member 21 includes a second transmission slide 213, which is located above the pot body assembly 2. A locking hole 2131 is provided on the lower surface of the second transmission slide 213, and the locking portion 31 includes an upwardly extending locking rod 313. When the self-locking member 30 is in the release position, the locking rod 313 is located below the locking hole 2131. When the self-locking member 30 is in the limit position, the locking rod 313 is inserted into the locking hole 2131. Specifically, a locking hole 2131 is provided on the lower surface of the second transmission slide 213. When the self-locking member 30 is in the limit position, the locking rod 313 is inserted into the locking hole 2131, and the locking rod 313 cooperates with the side wall stop of the locking hole 2131, thereby limiting the second transmission slide 213 from moving in the lateral direction; when the self-locking member 30 moves from the limit position to the release position, the self-locking member 30 moves downward as a whole, so that the locking rod 313 also moves downward and disengages from the locking hole 2131, so that the second transmission slide 213 can move in the lateral direction. The limitation or release of the second transmission slide 213 is achieved through the cooperation between the locking rod 313 that can be moved up and down and the locking hole 2131, which has the advantage of simple structure.

[0074] like Figure 8 As shown, the trigger portion 32 is also a rod-shaped structure extending upward. The self-locking member 30 also includes a third guide post 34 extending downward. The portion of the mounting member 50 extending below the self-locking member 30 is provided with a mounting hole 51. The third guide post 34 is inserted into the mounting hole 51. The retaining member is a compression spring mounted on the third guide post 34. The two ends of the compression spring respectively abut the mounting member 50 and the self-locking member 30 to apply an upward force to the self-locking member 30.

[0075] like Figure 7 and Figure 14 As shown, the first transmission member 21 also includes a connecting plate 214 disposed within the pot body assembly 2 and connected to the second transmission slide 213. The connecting plate 214 is provided with second lower driven teeth 2141. The operating member 10 includes a second knob 13, which is provided with second lower driving teeth 131 that mesh with the second lower driven teeth 2141. Rotation of the second knob 13 drives the connecting plate 214 and the second transmission slide 213 to move. The provision of the connecting plate 214 between the second transmission slide 213 and the second knob 13 enables power transmission. Specifically, the second lower driving teeth 131 are gear teeth, while the second lower driven teeth 2141 are spur teeth disposed on the connecting plate 214. The meshing between the second lower driving teeth 131 and the second lower driven teeth 2141 converts rotation of the second knob 13 into lateral movement of the connecting plate 214 and the second transmission slide 213, resulting in a simple structure and reliable transmission.

[0076] Specifically, if Figure 7 and Figure 9As shown, a connecting column 2132 is provided below the second transmission slide 213 , and the connecting column 2132 can be inserted into the connecting cylinder on the connecting plate 214 to achieve a fixed connection between the second transmission slide 213 and the connecting plate 214 .

[0077] like Figure 7 、 Figure 10 and Figure 14 As shown, the second transmission member 22 includes a third transmission slide 223 disposed on the cover assembly 1 and a second transmission rocker 224 disposed above the third transmission slide 223. The third transmission slide 223 extends downward from the cover assembly 1 and moves synchronously with the second transmission slide 213. When the third transmission slide 223 moves, it causes the second transmission rocker 224 to swing, thereby driving the locking member 101 to switch between the locked position and the unlocked position. Specifically, the third transmission slide 223 can be coupled to the second transmission slide 213 to achieve synchronous movement of the third transmission slide 223 and the second transmission slide 213. A transmission rod is provided on the third transmission slide 223, which can cause the second transmission rocker 224 to swing.

[0078] Specifically, in this embodiment, a coupling groove is provided on the second transmission slide 213, and a coupling column extending downward is provided on the third transmission slide 223. The coupling column can be inserted into the coupling groove to enable the second transmission slide 213 and the third transmission slide 223 to move synchronously.

[0079] like Figure 7 and Figure 10 As shown, the second transmission rocker arm 224 is provided with a second rotating hole 2241, a second transmission hole 2242 and a third transmission hole 2243, wherein the transmission rod on the third transmission slide 223 can be extended into the second transmission hole 2242, and when the third transmission slide 223 moves, it drives the second transmission rocker arm 224 to swing along the axis of the second rotating hole 2241, and the transmission column 1012 on the locking component 101 is penetrated into the third transmission hole 2243. When the second transmission rocker arm 224 swings, it drives the transmission column 1012 to swing through the third transmission hole 2243, thereby driving the locking component 101 to switch between the locked position and the unlocked position.

[0080] like Figures 11 to 14 As shown, the present application also provides a cooking appliance comprising a pot assembly 2, a lid assembly 1 that is openably and closably mounted on the pot assembly 2, and a drive assembly disposed between the pot assembly 2 and the lid assembly 1, wherein the drive assembly is the aforementioned drive assembly.

The second guide post 2022 extends downwardly through the guide hole 33. The retaining member is a compression spring sleeved on the second guide post 2022. The lower end of the compression spring abuts against the portion of the mounting member extending below the self-locking member 30, and the upper end of the compression spring abuts against the self-locking member 30 to apply an upward force to the self-locking member 30.

[0085] like Figure 2 and Figure 13 As shown, a guide groove 2114 is provided on the first transmission slide 211 , and a first guide column 2021 is provided below the middle plate 202 .

The arcuate groove 2041 can guide the transmission rod 12 and limit its position. The middle plate 202 is provided with a coupling hole 2024, into which the first rotating coupling post 212 is inserted.

[0087] like Figure 11 and Figure 13 As shown, the cooking appliance further includes a locking hook 60 disposed within the pot body assembly 2. The locking hook 60 is a swinging structure capable of engaging with a fixed hook on the lid assembly 1. When no external force is applied, the locking hook 60 remains in the engaged position with the fixed hook. When the user turns the first knob, the transmission rod 12 can also push the locking hook 60 to disengage the locking hook 60 from the fixed hook.

[0088] like Figure 11 and Figure 13 As shown, two mounting plates 2025 are provided below the middle plate 202, and mounting holes are respectively provided on the two mounting plates 2025. Rotating shafts are provided on both sides of the locking hook 60, and the two rotating shafts are respectively installed in the two mounting holes, so that the locking hook 60 can be swingably installed on the middle plate 202.
