[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the utility model provides a cover assembly.

[0005] A second aspect of the present invention provides a cooking utensil.

[0006] In view of this, the first aspect of the utility model provides a cover assembly, which is used for a cooking utensil. The cooking utensil includes a pot body assembly. The cover assembly can be covered on the pot body assembly. The cover assembly includes: a cover body, a locking component, a transmission component, a drive component and a push rod component. The locking component is connected to the cover body and can rotate relative to the cover body. The locking component has a locked state and an unlocked state relative to the pot body assembly. The transmission component is connected to the locking component. The transmission component includes a first rack, and the first rack is provided with a first limiting portion. The drive component is connected to the first rack to drive the locking component to lock or unlock relative to the pot body assembly through the first rack. The push rod component is provided on the cover body, wherein when the cover assembly is separated from the pot body assembly, the locking component is in an unlocked state, the push rod component contacts the first limiting portion, and can prevent the locking component from switching to a locked state. When the cover assembly is covered on the pot body assembly, the push rod component is separated from the first limiting portion, and the locking component can switch to a locked state or an unlocked state.

[0007] The present application provides a cover assembly, which is used for a cooking utensil. The cooking utensil includes a pot body assembly, and the cover assembly can be covered on the pot body assembly. The cover assembly includes a cover body, a locking component, a transmission component, a drive component and a push rod component. The locking component is connected to the cover body and can rotate relative to the cover body. The locking component has a locked state and an unlocked state relative to the pot body assembly. The transmission component is connected to the locking component, and the transmission component can drive the locking component to switch between the locked state and the unlocked state, thereby improving the transmission efficiency. The transmission component includes a first rack, and the first rack is provided with a first limiting portion. The drive component is connected to the first rack to drive the locking component to lock or unlock relative to the pot body assembly through the first rack. Through the cooperation of the drive component, the locking component and the transmission component, the locking and unlocking actions of the locking component can be realized, reducing the difficulty of locking and unlocking operations and improving the working efficiency of the cooking utensil. By arranging the push rod assembly on the cover body, and when the cover assembly is separated from the pot body assembly, the locking component is in an unlocked state, the push rod assembly can contact the first limiting portion, and can prevent the locking component from switching to a locked state. When the user opens the cover assembly, the push rod assembly can limit the transmission assembly, and can further complete the limiting of the locking component, and lock the working state of the locking component, so that the locking component is fixed in an unlocked state. In the process of opening the cover, the locking component can be prevented from sliding to a non-unlocked state, which is convenient for subsequent closing operations, and prevents collisions between the locking component and the pot body assembly when closing the cover assembly. At the same time, it can also prevent the user from accidentally sliding the locking component to a locked state when cleaning or operating the cover assembly, and thus prevent the locking component from sliding to a locked state when the cover assembly is separated, which affects the rotation of the cover assembly and the pot body assembly, thereby improving the convenience and safety of the operation of the cooking utensil. Because when the cover assembly is covered on the pot body assembly, the push rod assembly is separated from the first limiting portion, and the locking component can be switched to a locked state or an unlocked state. In the process of closing the lid, the push rod assembly is separated from the first limiting part, allowing the locking component to switch freely to the locked or unlocked state according to the operation requirements, and removing the restriction of the push rod assembly on the locked state or unlocked state of the locking component, which can ensure the smooth progress of the closing process and avoid damage or failure of closing the lid caused by unnecessary collision between the locking component and the pot body assembly. At the same time, when the user buckles the lid assembly, there is no need to check the state of the locking component, thereby simplifying the operation steps when using the cooking utensil, facilitating the user's operation, improving the automation degree of the cooking utensil, reducing the user's operation time, and improving the practicality of the cooking utensil. Furthermore, due to the limit of the push rod assembly on the transmission assembly, the limit of the locking component can be further completed, the locking of the working state of the locking component can be achieved, and the locking component is fixed in the unlocked state, thereby preventing the user from accidentally touching the drive assembly and the transmission assembly of the cooking utensil to cause wear, thereby extending the service life of the drive assembly and the transmission assembly, and improving the durability of the cooking utensil.

[0008] Furthermore, the first limit portion provided on the first rack cooperates with the push rod assembly to form a mechanical limit device. When the lid assembly is in the open state, the push rod assembly contacts the first limit portion, limiting the further movement of the first rack, thereby preventing the locking component from being accidentally locked. When the lid assembly begins to close the lid, the push rod assembly separates from the first limit portion, unlocking the movement restriction of the first rack, so that the locking component can switch states freely as needed.

[0011] In this technical solution, the cover body is provided with a mounting hole, and the mounting hole can facilitate the movement of the push rod assembly in the cover assembly, thereby facilitating the push rod assembly to limit the locking component. The push rod assembly includes a push rod, a pressure plate and an elastic member, the push rod is arranged in the mounting hole, the pressure plate is connected to the cover body and pressed on the push rod, the first end of the elastic member is connected to the side of the pressure plate close to the pot body assembly, and the second end of the elastic member is connected to the push rod, and the elastic member can drive the push rod through its own expansion and contraction, which can improve the working stability of the push rod assembly, realize the automatic displacement of the push rod assembly, and improve the automation degree of the cover assembly. Among them, when the lid assembly is covered on the pot body assembly, the elastic member is in a compressed state, and the elastic member is deformed at this time. When the user opens the lid assembly again, the lid assembly is separated from the pot body assembly, and the elastic member releases elastic potential energy to achieve the resetting of the elastic member. Since the elastic member abuts against the pressure plate, the elastic member can drive the push rod assembly, so that the push rod assembly can abut against the first limiting portion, and the push rod assembly can limit the transmission assembly, further complete the limiting of the locking component, and achieve the locking of the working state of the locking component, so that the locking component is fixed in the unlocked state, which can prevent the user from accidentally sliding the locking component to the locked state when cleaning or operating the lid assembly, and further prevent the locking component from sliding to the locked state when the lid assembly is separated, which affects the screwing of the lid assembly and the pot body assembly, thereby improving the convenience and safety of the operation of the cooking appliance.

[0012] In some technical solutions of the present utility model, optionally, the push rod includes a mounting portion and a rod body, the mounting portion is arranged in the mounting hole and connected to the second end of the elastic member, the rod body is connected to the mounting portion and extends toward the first limiting portion.

[0016] In the technical solution, the push rod also includes a second limiting portion, which is arranged at one end of the rod body away from the mounting portion; when the cover assembly is separated from the pot body assembly, the second limiting portion contacts the first limiting portion, and the contact area between the push rod assembly and the first limiting portion can be reduced by the abutment between the second limiting portion and the first limiting portion, so as to avoid the rod body and the first limiting portion from getting stuck while achieving the limiting. Further, the push rod may not be additionally provided with a second limiting portion, and when the cover assembly is separated from the pot body assembly, the first limiting portion is limited by the cooperation between the rod body and the first limiting portion, and then the transmission assembly is limited, so that the locking component can be fixed in the unlocked state, so as to avoid the user accidentally touching the locking component to slide to the locked state when cleaning or operating the cover assembly, and then avoid the locking component sliding to the locked state when the cover assembly is separated, which affects the screwing of the cover assembly and the pot body assembly, thereby improving the convenience and safety of the operation of the cooking utensil.

[0017] In some technical solutions of the present invention, optionally, when the locking component switches from an unlocked state to a locked state, the locking component rotates along a first direction; when the lid assembly is separated from the pot body assembly, the second limiting portion is located to the side of the first limiting portion in the first direction.

[0018] In this technical solution, when the locking component switches from the unlocked state to the locked state, the locking component rotates along the first direction; when the lid assembly is separated from the pot body assembly, the second limiting portion is located on the side of the first limiting portion in the first direction, and when the lid assembly of the cooking utensil is buckled on the pot body assembly, the second limiting portion on the push rod assembly and the first limiting portion are staggered in the first direction, so the second limiting portion at this time will not affect the movement of the first limiting portion in the first direction. At this time, the user can operate the lid assembly to screw on or open. At the same time, after the use of the cooking utensil is finished, when the user operates the locking component to be in the unlocked state, the second limiting portion can abut against the first limiting portion, thereby completing the limiting of the transmission assembly and limiting the locking component to be in the unlocked state, avoiding the locking component from being in the locked state due to accidental touch, and further preventing the locking component from sliding to the locked state when the lid assembly is separated and affecting the screwing of the lid assembly and the pot body assembly, thereby improving the convenience and safety of the operation of the cooking utensil.

At the same time, after the use of the cooking utensil is finished, when the user operates the locking component to be in the unlocked state, the elastic member can realize that the second limiting portion automatically abuts against the first limiting portion, thereby completing the limiting of the transmission component, and limiting the locking component to be in the unlocked state, thereby improving the stability of the operation of the cover assembly.

[0021] In some technical solutions of the present invention, optionally, when the cover assembly is separated from the pot body assembly, the push rod protrudes from a side of the cover body close to the pot body assembly; when the cover assembly is covered on the pot body assembly, the push rod abuts against the pot body assembly.

[0022] In this technical solution, when the cover assembly is separated from the pot body assembly, the push rod protrudes from the side of the cover body close to the pot body assembly; when the cover assembly is placed on the pot body assembly, the push rod abuts against the pot body assembly, and through the limitation of one end of the push rod assembly by the pot body assembly, the push rod assembly can be displaced relative to the cover assembly, and then through the abutment between the push rod assembly and the pot body assembly, the push rod assembly can be driven to release the limitation on the first rack.

The sleeve is sleeved on the first mounting column and is located in the first sliding groove. When the driving assembly drives the locking component through the transmission assembly, the first rack moves relative to the first mounting column through the first sliding groove. Since the sleeve is sleeved on the first mounting column, the first rack contacts the sleeve during the sliding process of the transmission assembly. At the same time, since the sleeve is sleeved on the first mounting column, the sleeve can rotate on the first mounting column. Therefore, the setting of the sleeve enables the first rack to slide and rub against the first mounting column through the sleeve, thereby reducing the friction resistance of the first rack during the sliding process, improving the flexibility of the transmission assembly, and at the same time, reducing the friction resistance of the transmission assembly during the transmission process, and extending the service life of the transmission assembly.

The locking component 120 is connected to the cover body 110 and can rotate relative to the cover body 110. The locking component 120 has a locked state and an unlocked state relative to the pot body assembly 220. The transmission component 130 is connected to the locking component 120. The transmission component 130 includes a first rack 132. The first rack 132 is provided A first limiting portion 128 is provided, and the driving assembly 140 is connected to the first rack 132 to drive the locking component 120 to lock or unlock relative to the pot body assembly 220 through the first rack 132. The push rod assembly 150 is arranged on the cover body 110, wherein, when the cover assembly 100 is separated from the pot body assembly 220, the locking component 120 is in an unlocked state, and the push rod assembly 150 contacts the first limiting portion 128, which can prevent the locking component 120 from switching to a locked state. When the cover assembly 100 is covered on the pot body assembly 220, the push rod assembly 150 is separated from the first limiting portion 128, and the locking component 120 can switch to a locked state or an unlocked state.

[0056] A cover assembly 100 is provided in the present application. The cover assembly 100 is used for a cooking utensil 200. The cooking utensil 200 includes a pot body assembly 220. The cover assembly 100 can be covered on the pot body assembly 220. The cover assembly 100 includes a cover body 110, a locking component 120, a transmission assembly 130, a drive assembly 140 and a push rod assembly 150. The locking component 120 is connected to the cover body 110 and can rotate relative to the cover body 110. The locking component 120 has a locked state and an unlocked state relative to the pot body assembly 220. The transmission assembly 130 is connected to the locking component 120. The transmission assembly 130 can drive the locking component 120 to switch between the locked state and the unlocked state, thereby improving the transmission efficiency. The transmission assembly 130 includes a first rack 132, and the first rack 132 is provided with a first limiting portion 128. The driving assembly 140 is connected to the first rack 132 to drive the locking component 120 to lock or unlock relative to the pot body assembly 220 through the first rack 132. Through the cooperation of the driving assembly 140, the locking component 120 and the transmission assembly 130, the locking and unlocking actions of the locking component 120 can be realized, thereby reducing the difficulty of locking and unlocking operations and improving the working efficiency of the cooking appliance 200.

Since the push rod assembly 150 is separated from the first limiting portion 128 when the lid assembly 100 is covered on the pot body assembly 220, the locking component 120 can be switched to a locked state or an unlocked state. In the process of closing the lid, the push rod assembly 150 is separated from the first limiting portion 128, allowing the locking component 120 to freely switch to a locked state or an unlocked state according to the operation requirements, and the restriction of the push rod assembly 150 on the locking state or the unlocking state of the locking component 120 can be released, so that the closing process can be smoothly carried out, and damage or closing failure caused by unnecessary collision between the locking component 120 and the pot body assembly 220 can be avoided.

[0057] At the same time, when the user snaps on the cover assembly 100, there is no need to additionally check the status of the locking component 120, thereby simplifying the operating steps when using the cooking utensil 200, facilitating user operation, improving the automation level of the cooking utensil 200, reducing the user's operating time, and improving the practicality of the cooking utensil 200.

[0058] Specifically, when the user is cleaning the cooking utensil 200, the user may easily touch the locking component 120 on the cover assembly 100, causing the locking component 120 to rotate, or touch the control button of the driving component 140, thereby driving the driving component 140 to move and drive the locking component 120 to rotate. By setting the push rod assembly 150 to contact the first limiting portion 128 after the cover is opened, the locking component 120 can be blocked from switching to a locked state. When the user opens the cover assembly 100, the push rod assembly 150 can limit the transmission assembly 130, thereby limiting the locking component 120 to be in an unlocked state, reducing the risk of damage, and facilitating subsequent cover closing operations.

[0059] Furthermore, if Figure 1 , Figure 3 and Figure 4 As shown, due to the limitation of the transmission assembly 130 by the push rod assembly 150, the locking component 120 can be further limited, and the working state of the locking component 120 can be locked, so that the locking component 120 is fixed in an unlocked state, which can prevent the user from accidentally touching the transmission structure of the cooking utensil 200 and causing wear.

[0060] Furthermore, the first limiting portion 128 provided on the first rack 132 cooperates with the push rod assembly 150 to form a mechanical limiting device. When the lid assembly 100 is in the open state, the push rod assembly 150 contacts the first limiting portion 128, limiting the further movement of the first rack 132, thereby preventing the locking component 120 from being accidentally locked. When the lid assembly 100 begins to close the lid, the push rod assembly 150 separates from the first limiting portion 128, unlocking the movement restriction of the first rack 132, so that the locking component 120 can switch states freely as needed.

[0061] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0062] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the cover body 110 is provided with a mounting hole 112, and the push rod assembly 150 includes a push rod 160, a pressure plate 170 and an elastic member 180, the push rod 160 is arranged in the mounting hole 112, the pressure plate 170 is connected to the cover body 110, and is pressed on the push rod 160, the first end of the elastic member 180 is connected to a side of the pressure plate 170 close to the pot body assembly 220, and the second end of the elastic member 180 is connected to the push rod 160; wherein, when the cover assembly 100 is separated from the pot body assembly 220, the elastic member 180 is in a compressed state.

[0063] In this embodiment, the cover body 110 is provided with a mounting hole 112, and the mounting hole 112 can facilitate the movement of the push rod assembly 150 in the cover assembly 100, thereby facilitating the push rod assembly 150 to limit the locking component 120.

When the lid assembly 100 is covered on the pot body assembly 220, the elastic member 180 is in a compressed state. At this time, the elastic member 180 is deformed. When the user opens the lid assembly 100 again, the lid assembly 100 is separated from the pot body assembly 220, and the elastic member 180 releases elastic potential energy to achieve the reset of the elastic member 180. Since the elastic member 180 abuts against the pressure plate 170, the elastic member 180 can drive the push rod assembly 150, so that the push rod assembly 150 can abut against the first limit portion 128, and the push rod assembly Component 150 can limit the transmission component 130, further complete the limitation of the locking component 120, and realize the locking of the working state of the locking component 120, so that the locking component 120 is fixed in the unlocked state, which can prevent the user from accidentally sliding the locking component 120 to the locked state when cleaning or operating the cover assembly 100, and further prevent the locking component 120 from sliding to the locked state when the cover assembly 100 is separated and affecting the screwing of the cover assembly 100 and the pot body assembly 220, thereby improving the convenience and safety of operating the cooking appliance 200.

[0094] In this embodiment, the locking component 120 includes a third body 122 and a second mounting column 124. The second mounting column 124 is penetrated by the cover body 110. The first end of the second mounting column 124 is connected to the first rack 132, and the second end of the second mounting column 124 is connected to the third body 122. When the cover assembly 100 is rotated to open and close, the driving component 140 can drive the transmission component 130 to slide relative to the first mounting column 116. Since the first end of the second mounting column 124 is connected to the first rack 132, when the transmission component 130 slides, the second mounting column 124 is driven by the first rack 132. Since the second mounting column 124 is connected to the third body 122, the driving component 140 can drive the locking component 120 through the transmission component 130 to realize the rotation opening and closing of the cover assembly 100.

[0095] like Figure 1 and Figure 7 As shown, in an embodiment of the present invention, a cooking utensil 200 is provided, comprising a lid assembly 100 as in any one of the above embodiments. The locking component 120 comprises a plurality of first lock buckles 126, which are arranged at intervals along the circumference of the third body 122 of the locking component 120; the pot body assembly 220 is provided with a second lock buckle 260; wherein, when the locking component 120 is in the first position, the plurality of first lock buckles 126 are engaged with the plurality of second lock buckles 260; when the locking component 120 is in the second position, the plurality of first lock buckles 126 are staggered with the plurality of second lock buckles 260.

[0096] The present application provides a cooking utensil 200, comprising a lid assembly 100 as in any one of the above embodiments. Therefore, the cooking utensil 200 has all the beneficial effects of the lid assembly 100 as in any one of the above embodiments. The locking component 120 comprises a plurality of first lock buckles 126, which are arranged at intervals along the circumference of the third body 122 of the locking component 120; the pot body assembly 220 is provided with a second lock buckle 260; wherein, when the locking component 120 is in the first position, the plurality of first lock buckles 126 are engaged with the plurality of second lock buckles 260; when the locking component 120 is in the second position, the plurality of first lock buckles 126 are staggered with the plurality of second lock buckles 260. The first lock buckle 126 and the second lock buckle 260 can be used to achieve the engagement and separation between the pot assembly 220 and the locking member 120. When the cooking utensil 200 is working, the locking member 120 can be adjusted to the first position, and the first lock buckle 126 and the second lock buckle 260 can be engaged with each other to complete the closure of the pot assembly 220 of the cooking utensil 200, which is convenient for cooking. After the cooking utensil 200 is finished, the locking member 120 can be adjusted to the second position, and the first lock buckle 126 and the second lock buckle 260 can be staggered with each other, and then no longer abut each other, so as to achieve the separation of the lid assembly 100 and the pot assembly 220, and the user can freely close and open the lid assembly 100. The structure of the engagement of the first lock buckle 126 and the second lock buckle 260 can ensure the free switching of the engagement and separation state between the pot assembly 220 and the locking member 120, and can also simplify the internal structure of the cooking utensil 200 and optimize the installation space.

[0097] When the user opens the lid assembly 100, the first lock buckle 126 and the second lock buckle 260 are in a mutually staggered state. By setting the push rod assembly 150 to limit the transmission assembly 130, the locking component 120 can be fixed to prevent the first lock buckle 126 from shifting due to the user's contact with the locking component 120, thereby ensuring that the first lock buckle 126 and the second lock buckle 260 are in a mutually staggered state, facilitating subsequent lid closing operations and preventing collisions between the first lock buckle 126 and the second lock buckle 260 when closing the lid assembly 100, thereby reducing the user's operating difficulty and improving the safety of the cooking utensil 200.

[0098] Furthermore, when the user uses the cooking utensil 200, since the push rod assembly 150 in the cooking utensil 200 is disposed on the cover body 110, and when the cover assembly 100 is separated from the pot body assembly 220, the locking component 120 is in the unlocked state, the push rod assembly 150 can contact the first limiting portion 128, which can prevent the locking component 120 from switching to the locked state. When the user opens the cover assembly 100 of the cooking utensil 200, the push rod assembly 150 on the cover assembly 100 can limit the transmission component 130. , the locking member 120 can be further limited, the working state of the locking member 120 can be locked, and the locking member 120 can be fixed in the unlocked state, which can prevent the user from accidentally sliding the locking member 120 to the locked state when cleaning or operating the lid assembly 100, thereby preventing the lid assembly 100 and the pot body assembly 220 from being affected by the locking member 120 sliding to the locked state when the lid assembly 100 is separated after use, thereby improving the convenience and safety of the operation of the cooking utensil 200. Since the push rod assembly 150 is separated from the first limiting portion 128 when the lid assembly 100 is covered on the pot body assembly 220, the locking member 120 can be switched to the locked state or the unlocked state. During the process of closing the lid, the push rod assembly 150 is separated from the first limit portion 128, allowing the locking component 120 to freely switch to a locked or unlocked state according to operational requirements, thereby releasing the restriction of the push rod assembly 150 on the locked state or unlocked state of the locking component 120, thereby ensuring the smooth progress of the lid closing process and avoiding damage or lid closing failure caused by unnecessary collisions between the locking component 120 and the pot body assembly 220.

Specifically, the pot assembly 220 can be provided with only the pot body 230, that is, the inner pot 240 and the pot body 230 are an integrated structure, which can reduce costs and improve internal stability.

[0103] Furthermore, the second lock 260 can be provided on the inner pot 240, and the inner pot 240 and the pot body 230 can be separated from each other. When the cooking utensil 200 is working, the user can place the inner pot 240 in the pot body 230, and then snap the lid assembly 100 to drive the locking component 120 to the first position, so that the first lock 126 and the second lock 260 on the inner pot 240 are mutually engaged, thereby completing the snapping of the lid assembly 100. Since the second lock 260 is provided on the inner pot 240, when the inner pot 240 is not provided in the pot body 230, even if the lid assembly 100 is covered on the pot body assembly 220, the user cannot snap the lid assembly 100 and the pot body assembly 220 together, which can prevent the user from operating the cooking utensil 200 without placing the inner pot 240, and can remind the user to improve the safety of the cooking utensil 200 and facilitate use.

[0104] Specifically, when the cover assembly 100 is buckled, the circumferential direction of the inner pot 240 is in the same direction as the circumferential direction of the third body 122 , that is, the direction indicated by the arrow Z.

[0105] Specifically, the circumferential direction of the third body 122 is the direction indicated by the arrow Z.

[0106] Specifically, the number of the first locks 126 can be set according to actual needs of the cooking appliance 200 .

[0107] Specifically, the cooking appliance 200 may be an electric pressure cooker, a micro-pressure rice cooker, or the like.

[0108] Specifically, Figure 1 , Figure 3 and Fig. 9 As shown, a second body may also be provided on the shaft sleeve 190, and a through hole may be provided on the second body, so that the first mounting post 116 is penetrated in the through hole. The through hole is provided to facilitate the installation of the shaft sleeve 190 on the first mounting post 116. By providing the first mounting post 116 with the through hole, the first rack 132 may slide and rub against the first mounting post 116 through the shaft sleeve 190 through the cooperation between the first mounting post 116 and the through hole, thereby reducing the friction resistance of the first rack 132 during the sliding process, improving the flexibility of the transmission assembly 130, and at the same time, due to reducing the friction resistance of the transmission assembly 130 during the transmission process, the service life of the transmission assembly 130 may also be extended.

[0109] Specifically, the first rack 132 can be fastened to the cover 110 by a screw and sleeve structure, and the first rack 132 can also rotate freely in the rack movable groove provided on the cover 110. The driving assembly 140 can be a motor, which is fixed to the cover 110, and the motor is coaxial with the first gear 144, and the first gear 144 is meshed with the first rack 132, so as to drive the first rack 132 to rotate on the cover 110. The push rod assembly 150 is composed of a push rod 160, a push rod 160 pressure plate 170 and an elastic member 180, and the elastic member 180 can be a push plate spring, and the push rod assembly 150 is fixed to the cover 110 by screws. The rotation of the first rack 132 drives the locking component 120 to rotate, so that the locking component 120 is screwed or unscrewed with the second lock buckle 260 on the inner pot 240. The first limiting portion 128 on the first rack 132 can be a top rib or a convex rib. The push rod 160 has a second stopper 165 that coincides with the rotation direction of the first stopper 128 of the first rack 132. The second stopper 165 may be a convex rib. The second stopper 165 may clamp the first stopper 128 of the first rack 132 to prevent the first rack 132 from rotating. When the lid assembly 100 is engaged with the pot body assembly 220, the bottom of the push rod assembly 150 contacts the heat insulating ring 250, the compression spring on the push rod assembly 150 moves upward, the second stopper 165 on the push rod assembly 150 is misaligned with the top rib of the first rack 132, and the first rack 132 can rotate freely, driving the locking component 120 to rotate or unscrew the inner pot 240.

[0110] Specifically, Figure 7 , Figure 8 and Fig. 9As shown, when the lid assembly 100 and the pot body assembly 220 are opened, the bottom of the push rod assembly 150 is suspended in the air, and under the action of the compression spring in the push rod assembly 150, the push rod 160 will be pressed to the bottom. At this time, the second limiting portion 165 of the push rod assembly 150 coincides with the first limiting portion 128 of the first rack 132, and the first rack 132 cannot rotate freely, which can effectively prevent the lock from rotating after the lid is opened.

[0111] Specifically, by providing the push rod assembly 150, the motor control program of the inner cover assembly 100 of the cooking utensil 200 can be simplified, and the user experience can also be improved. To prevent the locking component 120 from rotating freely after the cover is opened, after the automatic unlocking cooking utensil 200 is powered on, it is no longer necessary to first detect the position of the first rack 132, and it is no longer necessary to reset the first rack 132 to the unlocking position of the locking component 120 before closing the cover. The control process will reduce the complexity of the program and reduce the waiting time for users.
