DETAILED DESCRIPTION

[0062] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.

[0063] At present, with the development of technology and the improvement of people's living standards, more and more cooking utensils appear in the kitchen to meet different cooking needs and preferences. These utensils not only improve the cooking efficiency, but also enrich the taste and nutrition of food.

[0064] There are various types of cooking utensils, including electric rice cookers, pressure cookers, electric slow cookers, etc. Taking the pressure cooker as an example, the pressure cooker uses steam pressure to speed up the cooking process through sealing. The working principle of the pressure cooker is to seal the air in the pot, so that the steam cannot escape, thereby generating higher pressure in the pot than atmospheric pressure. This increased pressure can raise the boiling point of water, allowing food to be cooked at a higher temperature, thereby shortening the cooking time, while also preserving the nutritional content and flavor of the food.

[0065] However, whether it is a pressure cooker using open fire or an electric heating pressure cooker, the convenience and operability of its use are of great concern to the majority of users. In particular, the operation mode of the pressure cooker cover opening and closing directly affects the convenience of product use. The main components of the pressure cooker include the pot body and the upper cover that can be opened and closed on the pot body. The upper cover is equipped with various opening and closing structures with the pot body to meet different use requirements and safety standards, mainly divided into falling cover type, screwing type and clamp type.

[0066] In the related art, when opening the cover, the user needs to operate one driving assembly to unlock the cover body and the pot body, and also needs to operate another driving assembly to switch the pot cover from the locked position to the unlocked position, and then the upper cover can be opened. When closing the cover, the user needs to operate one driving assembly to lock the cover body and the pot body, and also needs to operate another driving assembly to switch the pot cover from the unlocked position to the locked position. This design is relatively cumbersome for the operation of the upper cover, and is not convenient for the user to use.

[0067] Based on this, the embodiment of the present application provides an upper cover, aiming to improve the problem that the operation of the cooking utensil in the related art is not simple enough.

[0068] Please refer to Figures 1-2 In the embodiment of the present application, the cooking utensil 1000 can include one of a pressure cooker, an electric rice cooker and an electric stew pot, and the embodiment does not limit the specific type of the cooking utensil 1000. In order to facilitate the description of the following content, the cooking utensil 1000 of the following embodiment is a pressure cooker, and the advantages of the cooking utensil 1000 of the present application are introduced in detail.

[0069] Taking the pressure cooker as an example, the pot body 200 usually includes an outer pot and an inner pot. The inner pot is used to directly hold food, and is detachably arranged in the outer pot, which is convenient for the user to clean and replace, and can also prevent the user from directly contacting the surface of the heated inner pot, reducing the risk of scalding. The outer pot can act as a heat preservation layer to reduce heat loss, so that the food in the inner pot can be heated more quickly and uniformly.

[0070] The upper cover 100 is openably and closably arranged on the pot body 200. The pot body 200 includes an outer shell 210, an outer pot 220 and an inner pot 230. The upper cover 100 includes a cover body 110, an unlocking assembly 120, a pot cover 130, a transmission assembly 140 and a handle 150. The cover body 110 is detachably connected with the outer shell 210. The unlocking assembly 120 is movably arranged on the cover body 110, and is used to unlock the detachable connection between the cover body 110 and the outer shell 210. The pot cover 130 is rotatably connected with the cover body 110 and is arranged in the cover body 110. The pot cover 130 has a locked position for locking with the outer pot 220 and an unlocked position for unlocking with the outer pot 220. The transmission assembly 140 is drivingly connected with the unlocking assembly 120 and the pot cover 130. The handle 150 is arranged on the transmission assembly 140 and can move upward relative to the cover body 110 to sequentially move from a locked position to a first release position and a second release position. In the two strokes of switching the handle 150 from the locked position to the first release position and from the first release position to the second release position, the handle 150 can drive the pot cover 130 to switch from the locked position to the unlocked position through the transmission assembly 140, and can unlock the cover body 110 through the transmission assembly 140 and the unlocking assembly 120.

[0071] It should be noted that there are many ways for the unlocking assembly 120 to be movably mounted on the cover 110. The unlocking assembly 120 can be mounted on the cover 110 by sliding, or by rotating, and the specific manner is not limited herein. There are many ways for the unlocking assembly 120 to unlock the cover 110. For example, when the cover 110 is connected to the shell 210 by buckling and a buckling groove, the unlocking assembly 120 drives the buckle to exit the buckling groove to unlock the cover 110. For another example, when the cover 110 is connected to the shell 210 by plug-in and a plug-in groove, the unlocking assembly 120 drives the plug-in to exit the plug-in groove to unlock the cover 110, and the specific manner is not limited herein.

[0072] There are many ways for the pot cover 130 to be locked with the outer pot 220. For example, the outer circumferential side of the pot cover 130 is provided with a thread, the inner side wall of the outer pot 220 is provided with a thread groove, the pot cover 130 is in a locked position, the pot cover 130 and the outer pot 220 are locked by thread and thread groove cooperation, the outer pot 220 is in an unlocked position, and the thread and the thread groove are arranged at intervals in the circumferential direction of the cover 110. For another example, the outer circumferential side of the pot cover 130 is provided with a buckle part, the inner side wall of the outer pot 220 is provided with a buckle groove, the pot cover 130 and the outer pot 220 are locked by buckle part and buckle groove cooperation, the outer pot 220 is in an unlocked position, and the buckle part and the buckle groove are arranged at intervals in the circumferential direction of the cover 110, and the specific manner is not limited herein.

[0073] The transmission assembly 140 is in transmission connection with the unlocking assembly 120, and the transmission assembly 140 is in transmission connection with the pot cover 130. It should be noted that the transmission assembly 140 can drive the unlocking assembly 120 and the pot cover 130 to move simultaneously, or the transmission assembly 140 can first drive the pot cover 130 to rotate, and then drive the unlocking assembly 120 to move, or the transmission assembly 140 can first drive the pot cover 130 to rotate, and then stop the pot cover 130 from rotating, and only drive the unlocking assembly 120 to move, and the specific manner is not limited herein.

[0074] The handle 150 can have various shapes. The handle 150 can be arc-shaped, "7"-shaped, or any other shape that is convenient for a user to hold. The handle 150 can be integrally formed with the transmission assembly 140, connected to the transmission assembly 140 by threads, or connected to the transmission assembly 140 by a snap-fit. Preferably, the handle 150 is detachably connected to the transmission assembly 140. When the handle 150 or the transmission assembly 140 is damaged, only the corresponding part needs to be replaced, thereby reducing the maintenance cost.

[0075] In the two strokes of the handle 150 from the locking position to the first release position and from the first release position to the second release position, the handle 150 can drive the pot cover 130 to switch from the locked position to the unlocked position by the transmission assembly 140, and can drive the unlocking assembly 120 by the transmission assembly 140 to unlock the cover body 110. It can be understood that, in the two strokes of the handle 150 from the locking position to the first release position and from the first release position to the second release position, in one case, the transmission assembly 140 first drives the pot cover 130 to rotate to the unlocked position, and then drives the unlocking assembly 120 to unlock the cover body 110; in another case, the transmission assembly 140 first drives the unlocking assembly 120 to unlock the cover body 110, and then drives the pot cover 130 to rotate to the unlocked position.

[0076] The first release position and the second release position can be located in the direction in which the handle 150 approaches the transmission assembly 140 from the locking position. It can be understood that, the cover body 110 is unlocked and the pot cover 130 is switched to the unlocked position by pressing the handle 150. The first release position and the second release position can also be located in the direction in which the handle 150 is away from the transmission assembly 140 from the locking position. It can be understood that, the cover body 110 is unlocked and the pot cover 130 is switched to the unlocked position by lifting the handle 150. Preferably, the first release position and the second release position are located in the direction in which the handle 150 is away from the transmission assembly 140 from the locking position. In this way, after the upper cover 100 is unlocked, the handle 150 can be continuously lifted to open the upper cover 100.

[0077] When a user uses the cooking utensil 1000, the user first closes the upper cover 100, and then drives the handle 150 to switch to the locking position to drive the transmission assembly 140 to move and drive the unlocking assembly 120 to move, so that the cover body 110 is locked with the pot body 200, and the pot cover 130 is driven to rotate from the unlocked position to the locked position.

[0078] When the user needs to open the upper cover 100, the user needs to drive the handle 150 to switch from the locking position to the second release position through the first release position, the handle 150 drives the transmission assembly 140 to move to drive the unlocking assembly 120 to unlock the cover body 110, and the handle 150 drives the transmission assembly 140 to drive the pot cover 130 to rotate from the locking position to the unlocking position, and then the user opens the upper cover 100.

[0079] The upper cover 100 provided by the embodiment of the present application only needs to drive the handle 150 to move in the vertical direction, and when the handle switches from the unlocking position to the second release position through the first release position, the handle drives the transmission assembly 140 to move, thereby driving the pot cover 130 to rotate to switch the pot cover 130 from the locking position to the unlocking position, and driving the unlocking assembly 120 to move to unlock the upper cover 100. In this way, the user only needs to drive the handle to move in the vertical direction to unlock the pot cover 130 and the cover body 110, thereby simplifying the opening and closing cover operation steps of the cooking utensil 1000, facilitating the user to operate the cooking utensil 1000, and reducing the structure for driving the cover body 110 and the pot cover 130 to move respectively, thereby optimizing the structure of the cooking utensil 1000.

[0080] Please refer to Figures 3-4 In some embodiments of the present application, the transmission assembly 140 includes a transmission member 141 and a driven member 142, the transmission member 141 is installed in the cover body 110 in a lifting manner, the transmission member 141 is connected with the handle 150, and the transmission member 141 is in transmission connection with the unlocking assembly 120; the driven member 142 is rotatably installed in the cover body 110, and the driven member 142 is in transmission connection with the pot cover 130; when the handle 150 switches from the locking position to the first release position, the handle 150 drives the transmission member 141 to move in the vertical direction, and drives the driven member 142 to rotate to drive the pot cover 130 to rotate; when the handle 150 switches from the first release position to the second release position, the handle 150 drives the transmission member 141 to move in the vertical direction relative to the driven member 142, and drives the unlocking assembly 120 to unlock the cover body 110.

[0081] In this way, the user can drive the handle 150 from the locking position to the second release position through the first release position, so that the handle 150 first drives the transmission member 141 to move the driven member 142 to rotate, so as to drive the pot cover 130 to rotate from the locked position to the unlocked position, and then the transmission member 141 drives the unlocking assembly 120 to unlock the cover body 110, so as to facilitate the user to use the upper cover 100. The driving force required to rotate the pot cover 130 is large, so that the upper cover 100 can be prevented from being shaken out of the locking position, so that the handle 150 can be stably located in the locking position. At the same time, when the upper cover 100 is opened, the pot cover 130 is first rotated from the locked position to the unlocked position, and then the cover body 110 is unlocked, and the cover body 110 is limited by the pot body 200, so as to limit the pot cover 130 in the vertical direction, thereby reducing the contact between the pot cover 130 and the pot body 200 in the vertical direction, and further reducing the friction between the pot cover 130 and the pot body 200, so as to facilitate the user to open the upper cover.

[0082] It should be noted that the cover body 110 is first unlocked, so that the upper cover 100 as a whole can move in the vertical direction, so that the pot cover 130 can move relative to the pot body 200 in the vertical direction. When the user continues to drive the handle 150 to move in the vertical direction to drive the pot cover 130 to rotate, the pot cover 130 and the upper cover 100 move together in the vertical direction, so that the pot cover 130 presses the pot body 200 in the vertical direction, thereby increasing the friction between the pot cover 130 and the cover body 110.

[0083] It can be understood that when the user drives the handle 150 from the locking position to the first release position, the transmission member 141 moves relative to the pot cover 130 in the vertical direction, the transmission member 141 drives the driven member 142 to rotate relative to the pot cover 130, and the driven member 142 drives the pot cover 130 to rotate from the locked position to the unlocked position. When the user drives the handle 150 from the first release position to the second release position, the driven member 142 remains stationary, and the transmission member 141 moves in the vertical direction to drive the unlocking assembly 120 to move to unlock the pot cover 130.

[0084] It should be noted that the transmission member 141 is lifted and installed on the cover body 110, and the cover body 110 needs to limit the circumferential direction of the transmission member 141, so as to avoid the rotation of the transmission member 141. For example, the circumferential direction of the transmission member 141 is provided with a limiting portion, the cover body 110 is provided with a guide groove extending in the vertical direction, the limiting portion extends into the guide groove, and the circumferential direction of the transmission member 141 is limited by the cooperation between the groove wall of the guide groove and the limiting portion. For another example, the circumferential direction of the transmission member 141 is provided with a limiting groove extending in the vertical direction, the cover body 110 is provided with a guide column extending into the limiting groove, and the circumferential direction of the transmission member 141 is limited by the cooperation between the groove wall of the limiting groove and the guide column. Here, they will not be listed one by one.

[0085] It should be noted that the transmission member 141 is lifted and installed on the cover body 110, and the cover body 110 needs to limit the circumferential direction of the transmission member 141, so as to avoid the rotation of the transmission member 141. For example, the circumferential direction of the transmission member 141 is provided with a limiting portion, the cover body 110 is provided with a guide groove extending in the vertical direction, the limiting portion extends into the guide groove, and the circumferential direction of the transmission member 141 is limited by the cooperation between the groove wall of the guide groove and the limiting portion. For another example, the circumferential direction of the transmission member 141 is provided with a limiting groove extending in the vertical direction, the cover body 110 is provided with a guide column extending into the limiting groove, and the circumferential direction of the transmission member 141 is limited by the cooperation between the groove wall of the limiting groove and the guide column. Here, they will not be listed one by one.

[0086] Please refer to Figures 3-4 In some embodiments of the present application, the first release position is located between the second release position and the locking position. When the handle 150 is switched from the locking position to the first release position, the handle 150 drives the transmission member 141 to move in the vertical direction, and drives the driven member 142 to rotate, so as to drive the pot cover 130 to rotate. When the handle 150 is switched from the first release position to the second release position, the handle 150 drives the transmission member 141 to move in the vertical direction relative to the driven member 142, and drives the unlocking assembly 120 to unlock the cover body 110.

[0087] Specifically, please refer to Figures 4-5The one of the driving member 141 and the driven member 142 is provided with a straight sliding groove 143 and an inclined sliding groove 144 which are in communication with each other, and the inclined sliding groove 144 is in communication with the side of the straight sliding groove 143 which is close to the side of the pot cover 130 which is far away from the pot cover 130; the other of the driving member 141 and the driven member 142 is provided with a driving part 145, and when the handle 150 is switched from the locking position to the first release position, the driving part 145 is matched with the inclined sliding groove 144 to drive the driven member 142 to rotate; and when the handle 150 is switched from the first release position to the second release position, the driving part 145 is matched with the straight sliding groove 143 to make the driving member 141 move relative to the driven member 142 in the vertical direction.

[0088] In this way, when the driving member 141 moves in the vertical direction by matching the driving part 145 with the inclined sliding groove 144, the driven member 142 can be driven to rotate, and when the driving member 141 moves relative to the driven member 142 in the vertical direction by matching the driving part 145 with the straight sliding groove 143, the structure of the transmission assembly 140 is simplified.

[0089] It can be understood that when the driving member 141 is provided with the straight sliding groove 143 and the inclined sliding groove 144, the driven member 142 is provided with the driving part 145; and when the driven member 142 is provided with the straight sliding groove 143 and the inclined sliding groove 144, the driven member 142 is provided with the driving part 145. The straight sliding groove 143 is arranged in the vertical direction, and the extension direction of the inclined sliding groove 144 includes a first component and a second component, the first component is the vertical direction, and the second component is the rotating direction of the driven member 142.

[0090] Further, referring to Figure 4 The bottom of the inclined sliding groove 144 is provided with a limiting protrusion 144a, and when the handle 150 is located in the locking position, the driving part 145 is in abutment with the limiting protrusion 144a to limit the driving member 141 in the direction away from the second release position. In this way, the driving member 141 can be limited by the abutment between the limiting protrusion 144a and the driving part 145, so that the driving member 141 is prevented from being separated from the driven member 142.

[0091] Referring to Figure 6 In some embodiments of the present application, the upper cover 100 further comprises a pin 160 which is mounted on the circumferential side of the driven member 142, and the driving member 141 is recessed with a limiting recess 141a, and when the handle 150 is located in the second release position, the pin 160 is inserted and matched with the limiting recess 141a. In this way, when the handle 150 is located in the second release position, the pin 160 is inserted and matched with the limiting recess 141a, so that the handle 150 can be stably located in the second release position, and the driving member 141 is prevented from moving relative to the driven member 142 when the upper cover 100 is shaken, so that the handle 150 is prevented from being separated from the second release position.

[0092] Further, referring to Figure 5 , the limiting groove 141a is arranged along the circumference of the transmission member 141. In this way, when the transmission member 141 moves in the vertical direction to the same height as the pin 160, the pin 160 can extend into the limiting groove 141a, thereby avoiding the pin 160 and the limiting groove 141a being misaligned in the circumference of the driven member 142, causing the pin 160 to be unable to extend into the limiting groove 141a, and thus facilitating user operation of the upper cover 100.

[0093] Specifically, referring to Figure 6 , the driven member 142 is provided with a mounting cavity 142a and a through hole 142b communicating with the mounting cavity 142a, and the pin 160 is partially located in the mounting cavity 142a and can extend out of the mounting cavity 142a from the through hole 142b; the upper cover 100 further comprises a first reset member 170, one end of the first reset member 170 being connected with the cavity wall of the mounting cavity 142a, and the other end of the first reset member 170 being connected with the pin 160, the first reset member 170 being used to drive the pin 160 to extend out of the mounting cavity 142a. In this way, when the transmission member 141 moves in the vertical direction, the pin 160 is pressed by the transmission member 141, so that the pin 160 compresses the first reset member 170 and extends into the mounting cavity 142a, thereby reducing the rigid contact between the transmission member 141 and the pin 160, and further reducing the wear of the transmission member 141 and the pin 160. At the same time, when the handle 150 is located at the second release position, the first reset member 170 drives the pin 160 to extend out of the through hole 142b to extend into the limiting groove 141a.

[0094] The first reset member 170 can be a spring, which drives the pin 160 to move by the elastic force of the spring, or a magnet, which drives the pin 160 to move by the repulsive force or attractive force of the magnet, and here will not be listed one by one.

[0095] Referring to Figures 3-4 and Figures 8-9In some embodiments of the present application, the unlocking assembly 120 sequentially comprises, in the direction away from the driven member 142, an abutting segment 121 extending towards the driven member 142, an extending segment 122 extending at least in the vertical direction, and an unlocking segment 123. When the handle 150 is in the locked position, the transmission member 141 is spaced apart from the abutting segment 121 in the vertical direction. When the handle 150 is in the first release position, the transmission member 141 abuts against the abutting segment 121. In this way, during the switching of the handle 150 from the locked position to the first release position, the unlocking assembly 120 is spaced apart from the transmission member 141 in the vertical direction, thereby reducing the driving force required by the user to switch the handle 150 from the locked position to the first release position, and further facilitating the user to open the upper cover 100.

[0096] It should be noted that the transmission member 141 is always spaced apart from the abutting segment 121 when the handle 150 is switched from the locked position to the first release position, and the transmission member 141 abuts against the abutting segment 121 only when the handle 150 reaches the first release position. During the switching of the handle 150 from the first release position to the second release position, the transmission member 141 drives the abutting segment 121 to move, thereby driving the unlocking segment 123 to move and unlocking the cover body 110.

[0097] In some embodiments of the present application, the outer peripheral wall of the transmission member 141 is provided with a transmission portion 141b. When the handle 150 is switched from the locked position to the second release position, the transmission portion 141b abuts against the unlocking assembly 120 and drives the unlocking assembly 120 to unlock the cover body 110. In this way, by providing the transmission portion 141b on the outer peripheral wall of the transmission member 141 to drive the unlocking assembly 120, the unlocking assembly 120 can be spaced apart from the driven member 142 in the radial direction, thereby optimizing the structural layout of the upper cover 100 and avoiding the unlocking assembly 120, the transmission member 141 and the driven member 142 being installed at the same position of the upper cover 100.

[0098] The transmission portion 141b can be integrally formed with the transmission member 141, or can be detachably connected with the transmission member 141, which is not specifically limited herein.

[0099] The driven member 142 can be sleeved on the transmission member 141, in which case the transmission member 141 needs to be provided with a mounting protrusion, and the driven member 142 is movably mounted on the mounting protrusion, thereby avoiding the transmission portion 141b interfering with the driven member 142 when the transmission member 141 moves in the vertical direction. The transmission member 141 can also be sleeved on the driven member 142, which is not specifically limited herein.

[0100] Specifically, please refer to Figure 7The transmission member 141 is provided with a mounting hole 141c, and the transmission member 141 is sleeved on the driven member 142 through the mounting hole 141c. In this way, the transmission part 141b and the driven member 142 are arranged in the radial direction of the driven member 142, so as to avoid interference between the transmission part 141b and the driven member 142 when the transmission member 141 moves in the vertical direction. At the same time, the transmission part 141b and the driven member 142 can be arranged in the axial direction of the driven member 142, so as to reduce the space occupied by the transmission assembly 140 in the vertical direction, and further reduce the volume of the upper cover 100 as a whole.

[0101] Considering that the rotation axis of the driven member 142 and the rotation axis of the pot cover 130 are arranged in the radial direction of the driven member 142, a gear set or the like needs to be arranged to drive connect the driven member 142 and the pot cover 130. In view of this, please refer to Figures 1-2 The rotation axis of the driven member 142 and the rotation axis of the pot cover 130 are collinear. In this way, the driven member 142 can be directly driven connected with the pot cover 130, so as to reduce the arrangement of the gear set or the like, and further optimize the structure of the upper cover 100 as a whole. It can be understood that the driven member 142 is fixedly connected with the pot cover 130, and the driven member 142 drives the pot cover 130 to rotate.

[0102] Further, please refer to Figures 3-4 The driven member 142 is provided with a receiving groove 142c in the rotation axis direction of the driven member 142, the pot cover 130 is provided with a pressure relief port 131, the pressure relief port 131 is in communication with the receiving groove 142c, and the pressure relief port 131 is in the rotation axis direction of the driven member 142; the upper cover 100 further comprises an exhaust valve 180, the exhaust valve 180 is movably installed in the receiving groove 142c, so as to open or close the pressure relief port 131. In this way, when the pot cover 130 and the driven member 142 rotate, the exhaust valve 180 does not interfere with the pot cover 130, and at the same time, the space in the axial direction of the driven member 142 is fully utilized, so as to reduce the volume of the upper cover 100 as a whole.

[0103] It should be noted that the exhaust valve 180 can rotate together with the driven member 142 and the pot cover 130, or the exhaust valve 180 can be stationary, which is not limited here. When the exhaust valve 180 can rotate together with the driven member 142 and the pot cover 130, the driven member 142 can be driven connected with the pot cover 130 through the exhaust valve 180.

[0104] In the case of pressure cooking, the exhaust valve 180 blocks the pressure relief port 131, and the steam in the cooking cavity 240 of the pot body 200 cannot be freely released, and the boiling point of water is increased, thereby increasing the cooking temperature and pressure, and accelerating the cooking process of the food. In the case of pressureless cooking, the exhaust valve 180 at least partially leaves the pressure relief port 131, so that the pressure relief port 131 can communicate with the outside and the cooking cavity 240 of the pot body 200, thereby balancing the air pressure in the cooking cavity 240 and the outside.

[0105] For reference Figures 1-2 In some embodiments of the present application, the upper cover 100 further comprises an elastic member 190, one end of the elastic member 190 is connected with the cover body 110, and the other end of the elastic member 190 is connected with the pot body 200, and the elastic member 190 has a tendency to move the cover body 110 away from the pot body 200. In this way, after the unlocking assembly 120 unlocks the pot body 200 and the pot cover 130 is switched to the unlocked position, the elastic member 190 drives the cover body 110 to move away from the pot body 200 to open the upper cover 100, thereby facilitating the user to open the upper cover 100.

[0106] The elastic member 190 can be a spring, which drives the cover body 110 to move by the elastic force of the spring, the elastic member 190 can be a magnet, which drives the cover body 110 to move by the repulsive force or attractive force of the magnet, and the elastic member 190 can also be a torsion spring, which drives the cover body 110 to move by the elastic force of the torsion spring, and here we will not list them one by one.

[0108] For reference Figures 8-9In some embodiments of the present application, the cover 110 is provided with a clamping groove 111, the unlocking assembly 120 comprises a movable element 124 movably mounted on the cover 110, the clamping assembly 211 comprises a clamping element 211a movably mounted on the shell 210 and having a clamping portion 211b extending out of the shell 210, the clamping portion 211b is clamped and matched with the clamping groove 111; the movable element 124 partially extends into the clamping groove 111, when the transmission assembly 140 drives the unlocking assembly 120 to unlock the cover 110, the transmission assembly 140 drives the movable element 124 to move, so that the movable element 124 drives the clamping portion 211b to exit the clamping groove 111.

[0109] In this way, the cover 110 can be unlocked by driving the clamping portion 211b to move out of the clamping groove 111 through the movable element 124. The clamping element 211a can be movably mounted on the shell 210 in many ways, for example, the clamping element 211a is movably mounted on the shell 210 by sliding, the clamping element 211a is driven to slide by the movable element 124 to drive the clamping portion to exit the clamping groove 111; for example, the clamping element 211a is movably mounted on the shell 210 by rotating, the clamping element 211a is driven to rotate by the movable element 124 to drive the clamping portion 211b to exit the clamping groove 111, which will not be listed one by one.

[0111] The clamping portion 211b can be arranged on the outer circumferential wall of the shell 210 in many ways, for example, the clamping portion 211b is arranged on the surface of the shell 210 facing the cover 100, the cover 100 is provided with a recess facing the pot body 200, the clamping groove 111 is arranged on the groove wall of the recess, when the pot cover 130 seals the cooking cavity 240, the shell 210 is partially located in the recess, and the clamping portion 211b is clamped and matched with the clamping groove 111; for example, the clamping portion 211b is arranged on the surface of the shell 210 facing the cover 100, the clamping groove 111 is arranged on the surface of the cover 100 facing the pot body 200, which will not be listed one by one.

[0112] Specifically, please refer to Figures 8-9The activity piece 124 is rotatably installed on the cover 110. When the transmission assembly 140 drives the unlocking assembly 120 to unlock the cover 110, the transmission assembly 140 drives the activity piece 124 to rotate, so that the end of the activity piece 124 away from the transmission assembly 140 drives the buckling part 211b to exit the buckling groove 111. In this way, the activity piece 124 is rotatably installed in the pot body 200, which can reduce the space occupied by the activity piece 124, thereby reducing the overall volume of the cooking utensil 1000.

[0113] Further, please refer to Figures 8-9 The buckling assembly 211 further comprises a second reset piece 211c.
