Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cooking utensils, and particularly relates to a pressure cooker cover and a pressure cooker. BACKGROUND

[0002] In the field of kitchen utensils, as a commonly used cooking utensil, the connection mode of the cover and the body of the pressure cooker is crucial for the use experience and safety. The pressure cooker cover in the prior art has some deficiencies:

[0003] On the one hand, the locking mode of many pressure cooker covers in the prior art is relatively complex and inconvenient. For example, some covers adopt a rotary lock, which requires the user to accurately rotate the cover to a specific position when locking, so that the lock is fully aligned with the corresponding structure on the body to achieve locking. This process often needs to be tried several times, and especially for users with less strength (such as the elderly or children), the operation is difficult. Moreover, during cooking, the cover may be subjected to a certain impact force due to the pressure in the pot, and the traditional locking mode may loosen after long-term use, affecting the sealing performance between the cover and the body, and thus reducing the safety and cooking effect of the pressure cooker.

[0004] On the other hand, the traditional pressure cooker cover also has problems when placed. Most covers can only be placed flat on the table or other placement surface after being removed from the body, which requires a large flat space. In the case of limited kitchen space, especially when multiple kitchen utensils need to be used simultaneously during cooking, the flatly placed cover will make the kitchen countertop more cluttered, causing inconvenience to the user's operation, and even may cause the cover to slip and damage or cause other safety hazards due to improper placement.

[0005] In addition, after unlocking, if the user needs to place the cover again for a period of time (such as waiting for the food in the pot to cool down before proceeding to the next step), due to the lack of a suitable placement method, the user can only hold the cover or place it randomly, which not only makes it inconvenient for the user to perform other operations, but also may cause the user to be scalded by the cover due to its high temperature, further highlighting the deficiencies of the traditional pressure cooker cover design in terms of use convenience.

[0006] In summary, the traditional pressure cooker cover has many inconveniences in terms of locking, unlocking operation and placement, and cannot meet the growing demand of users for the convenience of kitchen utensil operation and efficient use of space, so it is necessary to improve the pressure cooker cover to solve these practical problems. SUMMARY

[0007] The utility model aims at solving one of the technical problems in the related art to some extent. Therefore, the utility model provides a pressure cooker cover which has the functions of convenient locking and unlocking and can be vertically placed in the unlocking state to save the placing space.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0009] A pressure cooker cover comprises a cover body, a locking mechanism arranged on the cover body, a handle, a transmission assembly and a locking piece.

[0010] The pressure cooker cover comprises a locking state and an unlocking state. In the locking state, the locking piece locks the cover body and a pot body matched with the cover body, so that the two are kept buckled. When the handle is rotated, the handle makes the locking piece unlock the buckled cover body and pot body through the transmission assembly, and the pressure cooker cover enters the unlocking state. In the unlocking state, the pressure cooker cover can be vertically placed on a placing surface with the help of the handle.

[0011] The locking mechanism composed of the handle, the transmission assembly and the locking piece can realize the locking and unlocking of the cover body and the pot body by only rotating the handle. The handle drives the locking piece through the transmission assembly, which simplifies the operation process and reduces the operation difficulty. Compared with the traditional locking mode which needs accurate rotation or complex operation, the user can more easily complete the locking and unlocking actions of the cover body, improving the convenience and efficiency of the operation.

[0012] The locking mechanism can ensure that the cover body and the pot body are tightly buckled in the locking state. Through reasonable structural design, the locking piece can effectively withstand the action of the pressure in the pot when locking, reducing the possibility of loosening caused by pressure impact, thereby improving the sealing performance between the cover body and the pot body and enhancing the safety and stability of the cooking effect of the pressure cooker during use.

[0013] The pressure cooker cover in the patent can be vertically placed on the placing surface with the help of the handle in the unlocking state. This design changes the traditional mode in which the cover body can only be placed horizontally, greatly saving the placing space. In the case of limited kitchen space, the vertically placed cover body can effectively reduce the occupation of the countertop space, making the kitchen countertop more tidy and orderly, and also avoiding the problems such as sliding and damage caused by random placement of the cover body. This design provides great convenience for the user during use of the pressure cooker, whether the cover body is frequently used during cooking operation or placed after cooking is completed, which is more in line with the ergonomics and user's usage habits, improving the overall user experience.

[0014] Since the pressure cooker cover can be placed vertically after being unlocked, the user does not need to hold the cover when placing the cover to wait for the food in the pot to cool down or to perform other operations, thereby avoiding the risk of being scalded by the cover due to its high temperature. Meanwhile, the vertical placement provides a stable placement state for the cover, which is convenient for the user to take at any time, solves the inconvenience caused by improper placement of the cover after being unlocked, and improves the safety and convenience of the user during the use of the pressure cooker.

[0015] Optionally, the transmission assembly comprises a driving rack, a transmission gear and a driven rack, the handle drives the driving rack, the driving rack drives the driven rack through the transmission gear, and the driving rack and the driven rack are connected to the locking member respectively. Rotating the handle makes the driving rack and the driven rack produce opposite movements, and the driving rack and the driven rack drive the locking member to switch the pressure cooker cover between the locked state and the unlocked state.

[0016] In the patent, the transmission assembly adopts the structural design of a driving rack, a transmission gear and a driven rack, which further optimizes the locking and unlocking functions of the pressure cooker cover. The handle drives the driving rack, the driving rack drives the driven rack through the transmission gear, and both produce opposite movements to drive the locking member. This gear and rack transmission mode has the characteristic of high accuracy, which can ensure that the locking member moves accurately during locking and unlocking, making the cover and the pot body fit more tightly and stably, effectively preventing the situation of safety hazards caused by insecure locking during cooking. At the same time, the accurate transmission also makes the unlocking process smoother, and the user needs less force when operating, further improving the operation convenience of the pressure cooker cover, especially for users with less strength, making it easier to use.

[0017] Optionally, the driving rack comprises a rack part and a driving part, the driving part has a driving groove, the handle has a driving block, the driving block extends into the driving groove, and the handle rotates to drive the driving block to rotate, and the driving block drives the driving rack in the driving groove.

[0018] In the patent, the driving part of the driving rack is provided with a driving groove, and the driving block of the handle extends into the driving groove, which enhances the connection reliability and transmission stability between the handle and the driving rack. When the handle is rotated, the driving block drives the driving rack in the driving groove, which makes the rotation of the handle more effectively converted into the linear motion of the driving rack, ensuring stable power transmission. Compared with the traditional connection method, this design reduces the risk of transmission failure caused by loose or slippery connection, thereby improving the service life and reliability of the entire locking mechanism. In addition, the matching structure of the driving groove and the driving block is relatively simple, easy to process and manufacture, reduces the production cost, and is conducive to large-scale production and popularization and application of the product.

[0019] Optionally, the driving rack and the driven rack are respectively provided with a slot, and the locking member is provided with a plug pin which extends into the slot to drive the locking member.

[0020] In the patent, the driving rack and the driven rack are respectively provided with a slot, and the locking member is provided with a plug pin which extends into the slot, so that the connection between the locking member and the transmission assembly is more stable and easy to implement. This plug-in connection method not only facilitates installation and assembly during production, improving production efficiency, but also ensures accurate locking and unlocking actions of the locking member under the drive of the transmission assembly during use. The cooperation of the plug pin and the slot can effectively transmit power, avoiding power loss or deviation during transmission, ensuring reliable locking of the locking member to the pot cover body and the pot body, and further improving the safety and stability of the pressure cooker. At the same time, this connection structure is relatively compact and does not occupy too much space, which is conducive to the optimal design of the overall structure of the pressure cooker cover.

[0021] Optionally, the transmission assembly further comprises a limiting frame, and the driving rack and the driven rack move in opposite directions within the limiting frame.

[0022] In the patent, the limiting frame provides guidance and limitation for the movement of the driving rack and the driven rack, ensuring the accuracy and stability of their direction during movement. During the locking and unlocking of the pressure cooker cover, the driving rack and the driven rack need to move in a predetermined direction, and the presence of the limiting frame can prevent them from deviating, shaking or jamming during movement. This not only improves the working efficiency of the transmission assembly, making the locking and unlocking operation more rapid and smooth, but also reduces wear and damage caused by abnormal movement of the components, prolonging the service life of the transmission assembly. In addition, the limiting frame can also enhance the integrity and stability of the internal structure of the pressure cooker cover, and when subjected to external impact (such as accidental falling of the cover), it can protect the transmission assembly from damage and ensure normal use of the pressure cooker cover, thereby improving the overall reliability and safety of the pressure cooker.

[0023] Optionally, the locking mechanism comprises a cover shell, the cover shell is arranged on the pot cover body, the transmission assembly is located in the space formed by the cover shell and the pot cover body, and the handle is rotationally connected with the cover shell, and in the locked state, the handle is attached to the cover shell.

[0024] The locking mechanism in the patent is provided with a cover shell, the transmission assembly is located in the space formed by the cover shell and the pot cover body, the handle is rotationally connected with the cover shell and is in close contact with the cover shell in the locked state, which has many beneficial effects. First, the cover shell can protect the transmission assembly, prevent impurities such as dust and oil stains from entering the inside of the transmission assembly, affect its normal work, and thus ensure the reliability and service life of the locking mechanism. Second, this structure makes the appearance of the pressure cooker cover more neat and beautiful, and improves the overall quality of the product. Third, in the locked state, the handle is in close contact with the cover shell, which not only makes the pressure cooker cover more compact in appearance, but also avoids accidental unlocking caused by accidental touch of the handle during use, thereby improving the safety of the pressure cooker. In addition, the rotational connection between the handle and the cover shell makes the user operate the handle more smoothly and better in hand feeling, further optimizing the user experience.

[0025] Optionally, the cover shell is provided with a positioning protrusion, the handle is provided with a positioning block movable slot, the positioning block movable slot is provided with a positioning block, a spring is arranged between the positioning block movable slot and the positioning block, the positioning protrusion is provided with an abutting surface, and the positioning block is provided with a first positioning surface and a second positioning surface. In the locked state, the first positioning surface of the positioning block is abutted with the abutting surface of the positioning protrusion by the spring, and in the unlocked state, the second positioning surface of the positioning block is abutted with the abutting surface of the positioning protrusions by the spring.

[0026] The cooperation of the positioning protrusion of the cover shell, the positioning block, the positioning block movable slot and the spring of the handle in the patent provides clear positioning of the handle in the locked and unlocked states. In the locked state, the first positioning surface of the positioning block is abutted with an abutting surface of the positioning protrusion by the spring, ensuring that the handle is in close contact with the cover shell, preventing accidental rotation of the handle, and further enhancing the stability and safety of the locking. In the unlocked state, the second positioning surface of the positioning block is abutted with the abutment surface of the positioning protrusion by the spring, so that the handle can be stably kept in the unlocked position, facilitating the user to perform subsequent operations such as standing the pot cover. This positioning method improves the accuracy and reliability of the operation of the pressure cooker cover, and the user can clearly feel the positioning feedback of the handle in different states during use, reducing the operation errors caused by uncertain position of the handle, and improving the use quality and humanized design level of the product.

[0049] Embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numbers represent the same or similar elements or elements having the same or similar functions throughout. Based on the embodiments in the embodiments, it is intended to explain the present application, and cannot be understood as a limitation of the present application.

[0050] In this specification, "one embodiment" or "an embodiment" or "example" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the patent disclosure. The appearance of the phrase "in one embodiment" at various locations in the specification is not necessarily all referring to the same embodiment.

[0051] Embodiment one:

[0052] As Figure 1 shown, the present embodiment provides a pressure cooker cover, which comprises a pot cover body 1, further comprising a locking mechanism arranged on the pot cover body 1, the locking mechanism comprising a handle 21, a transmission assembly and a locking piece 23, the handle 21 being in transmission connection with the locking piece 23 through the transmission assembly. Specifically, as Figure 2 and Figure 3 shown, the transmission assembly comprises a driving rack 221, a transmission gear 222 and a driven rack 223. As Figure 4 shown, the driving rack 221 comprises a rack portion 2211 and a driving portion 2212. As the name implies, the rack portion 2211 is the position where the meshing teeth are arranged, and the driving portion 2212 is a cube shape and has a driving slot 2213. In the present embodiment, the opening direction of the driving slot 2213 is opposite to the direction of the meshing teeth, so as to facilitate processing and assembly. At the same time, the driving rack 221 is also provided with a first insertion slot 2214, in the present embodiment, the first insertion slot 2214 is located in the driving portion 2212, and the driving portion 2212 and the rack portion 2211 are integrally formed, so as to facilitate mold opening and save cost. As Figure 7As shown, the handle 21 has a drive block 211, which is integrally formed with the handle 21. The drive block 211 extends into the drive groove 2213. When the handle 21 rotates, it drives the drive block 211 to rotate, and the drive block 211 actuates the active rack 221 in the drive groove 2213. In this embodiment, the drive part 2212 of the active rack 221 is provided with a drive groove 2213. The design of the drive block 211 of the handle 21 extending into the drive groove 2213 enhances the connection reliability and transmission stability between the handle 21 and the active rack 221. When the handle 21 is rotated, the drive block 211 actuates the active rack 221 in the drive groove 2213. This structure allows the rotation of the handle 21 to be more effectively converted into the linear motion of the active rack 221, ensuring stable power transmission. Compared with traditional connection methods, this design reduces the risk of transmission failure due to loose connection or slippage, thereby improving the service life and reliability of the entire locking mechanism. Furthermore, the mating structure of the drive groove 2213 and the drive block 211 is relatively simple, easy to process and manufacture, reduces production costs, and is conducive to large-scale production and widespread application of the product. Meanwhile, the locking component 23 is equipped with a pin 232. Specifically, as... Figure 6 As shown, the locking member 23 includes a locking hook portion 233 and a first connecting arm 231. In this embodiment, the locking hook portion 233 and the first connecting arm 231 are integrally formed. The first connecting arm 231 is provided with a clearance groove 234 to avoid pressure relief holes, pressure relief valves, and other mechanisms. A pin 232 is provided on the first connecting arm 231. The first connecting arm 231 and the drive rack 221 of the transmission assembly are connected via the pin 232 and the first slot 2214, so that the drive rack 221 of the transmission assembly pushes the locking hook portion 233 through the first connecting arm 231 to drive the locking member 23.

[0053] In this embodiment, the transmission gear 222 can rotate about its own axis of rotation. The handle 21 drives the driving rack 221 to move linearly, the driving rack 221 drives the transmission gear 222 to rotate, and the rotation of the transmission gear 222 drives the driven rack 223 to move linearly in the opposite direction to the movement of the driving rack 221. For example... Figure 5As shown, the driven rack 223 also has a second slot 2231 connected, and the locking piece 23 connected with the driven rack 223 of the transmission assembly is also provided with a plug 232, which is arranged on a first connecting arm 231, and the first connecting arm 231 and the driven rack 223 of the transmission assembly are connected through the plug 232 and the second slot 2231, so that the driven rack 223 of the transmission assembly drives the locking piece 23 by pushing the hook part 233 through the first connecting arm 231. The gear and rack transmission mode has the characteristics of high accuracy, and in the technical field of cooking utensils, it can ensure that the locking piece 23 moves accurately during the movement, so that the buckling between the pot cover and the pot body 3 is more tightly and stably, and effectively prevents the situation that safety hidden danger occurs in the cooking process due to the locking is not firm. At the same time, the accurate transmission also makes the unlocking process more smooth, and the user needs less strength when operating, which further improves the operation convenience of the pressure cooker cover, especially for users with less strength, it is more easy and comfortable to use. In the embodiment, the driving rack 221 and the driven rack 223 are connected through the plug 232 extending into the second slot 2231 of the locking piece 23, so that the connection between the locking piece 23 and the transmission assembly is more stable and easy to realize. This plug-in connection mode not only has convenient installation, is convenient for assembling in the production process, improves the production efficiency, and can ensure that the locking piece 23 accurately moves under the drive of the transmission assembly during use. The cooperation of the plug 232 and the second slot 2231 can effectively transmit power, avoid the situation that the power is lost or deviated during transmission, and ensure the reliable locking of the locking piece 23 to the pot cover body 1 and the pot body 3, which further improves the safety and stability of the pressure cooker. At the same time, this connection structure is relatively compact and does not occupy too much space, which is conducive to the optimal design of the overall structure of the pressure cooker cover.

[0054] As Figure 2 and Figure 3As shown, in the embodiment, the transmission assembly further comprises a limiting frame 224 fixedly arranged on the pot cover body 1. The specific fixing manner can be screw connection, riveting or other conventional manner in the field, which is not limited here. The driving rack 221 and the driven rack 223 move in opposite directions within the limiting frame 224. In the embodiment, the width of the inner side of the limiting frame 224 is the distance between the rack planes of the driving rack 221 and the driven rack 223 after the engagement of the driving rack 221, the transmission gear 222 and the driven rack 223, and the length of the limiting frame 224 is the farthest movement distance of the driving rack 221 or the driven rack 223. The limiting frame 224 provides guidance and limitation for the movement of the driving rack 221 and the driven rack 223, ensuring the direction accuracy and stability of the two during movement. During the movement of the transmission assembly, the driving rack 221 and the driven rack 223 need to move in a predetermined direction, and the presence of the limiting frame 224 can prevent them from deviating, shaking or jamming during movement. This not only improves the working efficiency of the transmission assembly, making the movement of the transmission assembly more rapid and smooth, but also reduces wear and damage caused by abnormal movement of the components, prolonging the service life of the transmission assembly. In addition, the limiting frame 224 can also enhance the integrity and stability of the internal structure of the pressure cooker cover, and when subjected to external impact (such as accidental falling of the pot cover), it can protect the transmission assembly from damage and ensure the normal use of the pressure cooker cover, thereby improving the overall reliability and safety of the pressure cooker.

[0055] As shown in Figure 1 and Figure 8 、 Figure 11 As shown, the locking mechanism of the embodiment further comprises a cover 24 arranged on the pot cover body 1, and the transmission assembly is located in the space formed by the cover 24 and the pot cover body 1. The cover 24 can protect the transmission assembly, prevent dust, oil stains and other impurities from entering the inside of the transmission assembly, affect its normal work, and thus ensure the reliability and service life of the locking mechanism. The handle 21 is rotationally connected with the cover 24. Specifically, as shown in Figure 8 、 Figure 9 、 Figure 10As shown, the cover 24 is provided with mounting ears 241, the handle 21 is provided with a avoiding hole, the mounting ears 241 extend into the avoiding hole to enter the inside of the handle 21, the corresponding positions of the mounting ears 241 and the handle 21 are provided with rotating shaft mounting holes, the mounting shaft 25 is inserted into the rotating shaft mounting holes, that is, the rotating connection of the handle 21 and the cover 24 is completed. The rotating connection mode provided by the embodiment is only one of various rotating connection modes in the prior art, and there are various rotating connection modes of the handle 21 and the cover 24 in the prior art, which are not limited here. The rotating connection mode of the handle 21 and the cover 24 makes the user operate the handle 21 more smoothly, and the hand feeling is better, which further optimizes the user's experience. The cover 24 is provided with a positioning protrusion 242, the handle 21 is provided with a positioning block movable slot 212, the positioning block movable slot 212 is provided with a positioning block 26, a spring 27 is arranged between the positioning block movable slot 212 and the positioning block 26, and in the embodiment, a blind hole 213 is arranged in the positioning block movable slot 212, and the spring 27 is arranged in the blind hole 213. The positioning protrusion 242 is provided with an abutting surface, and the positioning block 26 is provided with a first positioning surface and a second positioning surface.

[0056] The pressure cooker cover provided by the embodiment includes a locked state and an unlocked state. The locking hook portion 233 is formed with a first locking groove, and the pot body 3 has a pot rim extending outward. In the locked state, as shown in Figure 1 、 Figure 2 and Figure 3 , the driving rack 221 and the driven rack 223 are in the first limit position in the limiting frame 224, the edge of the pot cover body 1 and the pot rim extend into the first locking groove, so that the locking piece 23 locks the pot cover body 1 and the pot body 3 cooperating with the pot cover body 1, and then keeps the two in buckling. This structure can provide a larger locking force, ensure the tight connection between the pot cover and the pot body 3, effectively prevent the leakage of high-pressure gas in the pot, and improve the safety of the pressure cooker. Moreover, the locking piece 23 can effectively withstand the pressure in the pot when locked, reducing the possibility of loosening caused by pressure impact, thereby improving the sealing performance between the pot cover and the pot body 3, and enhancing the safety and stability of the cooking effect of the pressure cooker during use. At the same time, the handle 21 is attached to the cover 24, making the appearance of the pressure cooker cover more neat and beautiful, and improving the overall quality of the product. Furthermore, in the locked state, the handle 21 is attached to the cover 24, which not only makes the pressure cooker cover more compact in appearance, but also avoids accidental unlocking caused by accidental touch of the handle 21 during use, thereby improving the safety of the pressure cooker. At the same time, the spring 27 pushes the first positioning surface of the positioning block 26 to abut against the abutting surface of the positioning protrusion 242, providing a clear positioning for the handle 21 in the locked state. In the locked state, the spring 27 pushes the first positioning surface of the positioning block 26 to abut the abutting surface of the positioning protrusion 242, ensuring that the handle 21 is tightly attached to the cover 24, preventing accidental rotation of the handle 21, and further enhancing the stability and safety of the locking.

[0057] When the handle 21 is rotated, the handle 21 drives the driving block 211 to rotate, the driving block 211 drives the driving rack 221 to move linearly in the driving slot 2213, the driving rack 221 drives the transmission gear 222 to rotate, the transmission gear 222 drives the driven rack 223 to move linearly in the opposite direction of the driving rack 221. The driving rack 221 and the driven rack 223 move linearly in opposite directions, thereby driving the first connecting arm 231 to move, and the first connecting arm 231 drives the locking hook part 233 to move, so as to switch the pressure cooker cover between the locked state and the unlocked state. In this embodiment, the transmission assembly adopts the structure design of the driving rack 221, the transmission gear 222 and the driven rack 223, which further optimizes the locking and unlocking functions of the pressure cooker cover. Only by rotating the handle 21, the locking and unlocking of the cover and the pot body 3 can be realized. The handle 21 drives the locking piece 23 through the transmission assembly, and drives the first connecting arm 231 to drive the locking hook part 233 to act through the transmission assembly, so as to realize the locking and unlocking of the cover. The operation is convenient and fast, the operation process is simplified, and the operation difficulty is reduced. Compared with the traditional locking mode which needs to be rotated accurately or operated complicatedly, the user can more easily complete the locking and unlocking action of the cover, improves the convenience and efficiency of the operation. At the same time, the structure of the locking hook is relatively stable and reliable, and is not easy to deform or damage in the long-term use process, which ensures the service life of the pressure cooker cover and reduces the use cost of the user.

[0058] In the unlocked state, as shown in FIG. 6, the handle 21 is rotated to the unlocking position, the first connecting arm 231 is driven to move, and the locking hook part 233 is driven to move to the unlocking position, so as to realize the unlocking of the cover. In this embodiment, the handle 21 is rotated to the unlocking position, and the first connecting arm 231 is driven to move, thereby driving the locking hook part 233 to move to the unlocking position. The handle 21 is rotated to the unlocking position, and the first connecting arm 231 is driven to move, thereby driving the locking hook part 233 to move to the unlocking position. The handle 21 is rotated to the unlocking position, and the first connecting arm 231 is driven to move, thereby driving the locking hook part 233 to move to the unlocking position. The handle 21 is rotated to the unlocking position, and the first connecting arm 231 is driven to move, thereby driving the locking hook part 233 to move to the unlocking position. The handle 21 is rotated to the unlocking position, and the first connecting arm 231 is driven to move, thereby driving the locking hook part 233 to move to the unlocking position. Figure 11 , Figure 12 and Figure 13As shown, the driving rack 221 and the driven rack 223 are in the second limit position within the limit frame 224, the edge of the lid body 1 is disengaged from the first locking groove, so that the lid body 1 can be separated from the pot body 3, and the pressure cooker lid can be placed vertically on the placement surface by means of the handle 21. Specifically, the spring 27 pushes the second positioning surface of the positioning block 26 to abut against the abutting surface of the positioning protrusion 242, so that the handle 21 can be stably kept in the unlocked position, facilitating the user to perform subsequent operations such as vertical placement of the lid.

[0059] Since the pressure cooker lid can be placed vertically after being unlocked, the user does not need to hold the lid when placing it to wait for the food in the pot to cool down or to perform other operations, thereby avoiding the risk of being scalded by the excessively high temperature of the lid. At the same time, the vertical placement provides a stable placement state for the lid, facilitating the user to take it at any time, solving the inconvenience caused by improper placement of the lid after being unlocked, and improving the safety and convenience of the user during the use of the pressure cooker.

[0060] In addition, the embodiment also provides a pressure cooker, which comprises a pot body 3 and the aforementioned pressure cooker lid, as shown in Figure 1 、 Figure 2 、 Figure 8 、 Figure 11 and Figure 12 As shown, the pressure cooker lid can be buckled with the pot body 3.

[0061] Embodiment Two:

[0062] The difference between the embodiment and the first embodiment is that the locking member comprises a locking tongue part and a second connecting arm, the second connecting arm has the same structure as the first connecting arm of the first embodiment, and details are not repeated here. The second connecting arm is connected with the transmission assembly, and the connection mode is the same as that of the first embodiment, and details are not repeated here. The transmission assembly pushes the locking tongue part through the second connecting arm. The pot body is provided with an inwardly extending locking guide. In the locked state, the locking tongue part extends below the locking guide, and the locking guide is located between the pot cover body and the locking tongue part, so that the pressure cooker cover and the pot body remain in the buckling state. Turn the handle, the handle drives the second connecting arm to move through the transmission assembly, and the connection and driving mode is the same as that of the first embodiment, and details are not repeated here. The second connecting arm pulls the locking tongue part to retract, so that the locking tongue part is withdrawn below the locking guide, and the locking tongue part is misaligned with the locking guide, so that the pot cover body can be separated from the pot body.

[0063] The structure provided by the embodiment can realize the locking of the pot cover by using the structural characteristics of the pot body itself, without the need for additional complex locking structures, so that the overall structure of the pressure cooker cover is more simple and compact. When locked, the locking tongue part can effectively block the separation of the pot cover and the pot body, ensuring the stability of the pressure in the pot. When unlocked, the second connecting arm is driven by the transmission assembly to misalign the locking tongue part with the locking guide, so that the pot cover is easily unlocked. In addition, the locking member of this structure is relatively easy to manufacture during the manufacturing process, reducing production costs, and is also easy to maintain and repair during use, improving the practicality and economy of the product.
