[0037] There are generally two types of common pressure-bearing structures for pressure cookers: one is a rotating lock, on which a lock tooth is provided, and a corresponding pot body is provided with a pot tooth, and the pot cover and the pot body are locked or unlocked by rotating the lock. This structure is generally used in one-piece pressure cookers. Specifically, the upper cover of the one-piece pressure cooker generally includes an inner cover, and the lock is hoisted on the inner cover. The upper cover and the pot body are hinged, and the pot cover and the pot body cannot be completely separated. The inner cover needs to be able to rotate independently to lock and unlock, and the structure is relatively complex; the second is to set a radially movable clamp, and the pot cover and the pot body are clamped and locked by the clamp moving inward, and the pot cover and the pot body are unlocked by moving the clamp outward. Specifically, it is generally used in split pressure cookers, that is, the pot cover and the pot body can be disassembled and separated.

[0038] Currently, a radially movable clamp locking structure is used on a one-piece pressure cooker platform. However, there is a problem that when the upper cover is fastened with the pot body, the pot body interferes with the clamp, resulting in the upper cover and the pot body being unable to be fastened together.

[0039] In order to improve the above problems, the utility model provides a pot cover, please refer to Figures 1 to 8 , is a specific implementation of the pot cover proposed by the utility model, and the pot cover will be described in detail below in conjunction with specific drawings.

[0040] See also Figures 1 to 8The pot cover 100 includes a cover body 1, a locking structure 2 and an unlocking structure 3, wherein the cover body 1 is used to cover the pot body 200; the locking structure 2 includes a locking clamp 21 and a driving assembly 22 movably arranged on the cover body 1, wherein the locking clamp 21 has a locking position for locking the pot body 200 and a disengaging position for disengaging from the pot body 200 in its movable stroke, and the driving assembly 22 includes a driving member 221 movably arranged on the cover body 1 and a first elastic reset member 222 arranged between the driving member 221 and the cover body 1, and the driving member 2 The first elastic return member 222 is used to drive the drive member 221 to maintain the locking pliers 21 in the locked position; the unlocking structure 3 includes an unlocking member 31 which is at least partially movably extended from the cover body 1, and the drive member 221 is correspondingly provided with an unlocking portion 2211, so that when the cover body 1 is covered on the cooker body 200, the unlocking member 31 is pressed by the cooker body 200 to return to the cover body 1, and the unlocking portion 2211 is driven to drive the drive member 221 to drive the locking pliers 21 to move to the disengaged position.

[0041] In the technical solution of the utility model, the pot cover 100 includes the cover body 1 and the locking structure 2 and the corresponding unlocking structure 3 arranged on the cover body 1, the locking structure 2 mainly includes the locking pliers 21 and the driving assembly 22 that drives the locking pliers 21 to move, and the driving assembly 22 includes the driving member 221 that drives the locking pliers 21 and the first elastic reset member 222 arranged between the driving member 221 and the cover body 1, the first elastic reset member 222 is used to drive the driving member 221 to maintain the locking pliers 21 in the locked position, on the one hand, there is no need for manual locking operation, the operation is simplified and the user is prevented from closing the pot cover 100 On the other hand, the pot cover 100 can be kept locked or not locked in place, which affects the normal use. On the other hand, the locked state can be maintained to ensure the safety of use. Based on this, when the pot cover 100 is separated from the cooker body 200, the driving member 221 is still driven by the first elastic reset member 222 to maintain the locking clamp 21 in the locked position. At this time, the pot cover 100 is closed on the cooker body 200, and the locking clamp 21 will interfere with the locking structure 2 on the cooker body 200, so that the pot cover 100 cannot be normally closed on the cooker body 200. The unlocking operation of the locking clamp 21 must be completed manually before the pot cover 100 can be normally closed on the cooker body 200 and locked, which is cumbersome. Therefore, the present application further provides the unlocking structure 3 on the cover body 1, and the unlocking structure 3 includes the unlocking member 31 that can movably extend out of the cover body 1 and the unlocking portion 2211 that is provided on the driving member 221 and corresponds to the unlocking member 31. When the cover body 1 is covered on the cookware body 200, the unlocking member 31 is pressed against the cookware body 200 and is pressed back into the cover body 1 by the cookware body 200, thereby driving the unlocking portion 2211 to drive the driving member 221 to drive the locking clamp 21 to move to the disengaged position, so that the cover body 1 can be normally covered on the cookware body 200, realizing the automatic unlocking function and meeting the usage requirements.

[0042] It can be understood that in order to satisfy the function of the first elastic return member 222 in the locking structure 2 to automatically drive the driving member 221 to drive the locking clamp 21 to lock the pot cover 100 and the pot body 200 after the pot cover 100 is covered on the pot body 200, that is, to satisfy the automatic locking function of the pot cover 100 and the pot body 200 after the cover is closed, the unlocking member 31 should be able to cancel the drive of the unlocking part 2211 on the driving member 221 after the pot cover 100 is completely covered on the pot body 200. The structural setting for canceling the drive here needs to be based on the specific structural setting of the unlocking member 31 and the unlocking part 2211, and no specific limitation is made, mainly based on being able to realize the actual function. The following will specifically describe the specific structure of the unlocking member 31 and the unlocking portion 2211 proposed in the present application, and further describe a structure based on the specific structural arrangement of the unlocking member 31 and the unlocking portion 2211, which can cancel the driving of the unlocking member 31 on the unlocking portion 2211 after the pot cover 100 covers the pot body 200.

[0043] Specifically, the unlocking member 31 can abut against the unlocking portion 2211 to drive the movement, and the abutting surfaces of the two include a driving inclined surface that is at a certain angle to the movement direction of the driving member 221. When the unlocking member 31 is retracted into the cover body 1, it pushes the unlocking portion 2211 along the driving inclined surface to drive the driving member 221 to move. The unlocking member 31 is mainly used to drive the unlocking portion 2211 to move, that is, a guide structure can be set between the unlocking member 31 and the unlocking portion 2211, and the unlocking member 31 directly acts on the unlocking portion 2211 to drive the driving member 221. Alternatively, a transmission structure can be set between the unlocking member 31 and the unlocking portion 2211, and the transmission is transmitted through the transmission structure to drive the driving member 221 to move. This is not limited here, and it only needs to be able to achieve its driving function. In this embodiment, the unlocking member 31 is arranged opposite to the unlocking portion 2211, and at least one of the abutting surfaces of the unlocking member 31 and the unlocking portion 2211 is set as the driving inclined surface, so that when the unlocking member 31 is abutted against the unlocking portion 2211, the driving member 221 is guided and driven by the driving inclined surface to move, thereby meeting the above-mentioned functional requirements.

[0044] Furthermore, based on the above-mentioned driving structure setting of the unlocking member 31 and the unlocking portion 2211, the present application correspondingly proposes a structure that can cancel the driving of the unlocking portion 2211 by the unlocking member 31 after the pot cover 100 covers the pot body 200, that is, an avoidance structure 4 is also provided between the unlocking portion 2211 and the unlocking member 31 to form an avoidance area when the cover body 1 covers the pot body 200, and the unlocking member 31 moves to the avoidance area to avoid the unlocking portion 2211, so that the first elastic return member 222 drives the driving member 221 to drive the locking pliers 21 to move to the locking position. It can be understood that the main requirement is that after the pot cover 100 covers the cooker body 200, the unlocking member 31 can cancel the driving of the unlocking portion 2211, so that the driving member 221 can be driven by the first elastic return member 222 to drive the locking pliers 21 to lock the pot cover 100 and the cooker body 200. Therefore, at least one of the unlocking member 31 and the unlocking portion 2211 can be set to be movable. After the pot cover 100 covers the cooker body 200, it is manually operated to move so that the two are separated, thereby releasing the driving of the unlocking member 31 on the unlocking portion 2211. For example, the unlocking member 31 is set to be movable laterally on the cover body 1 to have a working position corresponding to the unlocking portion 2211. and away from the unlocking portion 2211, thereby achieving the above-mentioned function, but it is obvious that the method requiring manual operation is still relatively cumbersome, so in the present application, the avoidance structure 4 is provided between the unlocking portion 2211 and the unlocking member 31, so that when the pot cover 100 is covered on the cooker body 200, an avoidance area is formed at the avoidance structure 4, and the unlocking member 31 moves to the avoidance area to avoid the unlocking portion 2211, so as to release the driving of the unlocking portion 2211 by the unlocking member 31. At this time, the pot cover 100 is just covered on the cooker body 200, and the driving member 221 will be driven by the first elastic reset member 222 to drive the locking pliers 21 to lock the pot cover 100 and the cooker body 200. In this way, without manual operation, in the process of closing the pot cover 100 on the pot body 200, the unlocking member 31 gradually drives the unlocking part 2211 to drive the locking clamp 21 to move to the disengaged position, so that the locking clamp 21 will not interfere with the process of closing the pot cover 100 on the pot body 200, until the pot cover 100 is completely closed, and the unlocking member 31 moves to the avoidance area to avoid the unlocking part 2211. At this time, the unlocking part 2211 is no longer driven by the unlocking member 31, so that the driving member 221 is driven by the first elastic return member 222 to drive the locking clamp 21 to move to the locking position, so as to automatically complete the locking of the pot cover 100 and the pot body 200. The whole process does not require manual operation, the use process is smooth, and the use experience is good.

[0045] Specifically, the avoidance structure 4 includes a through hole 41 opened in the unlocking portion 2211 and an avoidance groove 42 arranged in the unlocking member 31. The unlocking member 31 passes over the through hole 41, so that the unlocking portion 2211 corresponds to the avoidance groove 42, and the first elastic return member 222 drives the driving member 221 to drive the unlocking portion 2211 to move in the avoidance groove 42. The main function of the avoidance structure 4 is that when the cover body 1 is covered on the cooker body 200, the unlocking member 31 and the unlocking portion 2211 move relatively to the avoidance area formed by the avoidance structure 4, and can avoid each other. Therefore, the avoidance structure 4 can be set as a slot located on the unlocking member 31. When the cover body 1 is covered on the cooker body 200, the unlocking member 31 moves to the end of the unlocking portion 2211 and escapes from the unlocking portion 2211. At this time, the end of the unlocking portion 2211 corresponds to the above-mentioned slot. Because the unlocking portion 2211 is no longer driven by the unlocking member 31, the first elastic reset member 222 resets and drives the driving member 221 to drive the unlocking portion 2211 to extend into the above-mentioned slot, thereby completing the locking of the cover body 1 and the cooker body 200. In this embodiment, the through hole 41 is actually provided on the unlocking portion 2211, and the avoidance groove 42 is provided on the unlocking member 31. The difference from the above method is that when the cover body 1 is covered on the cooker body 200, the unlocking member 31 does not escape from the unlocking portion 2211, but corresponds to the through hole 41 on the unlocking portion 2211 and passes through the unlocking portion 2211 through the through hole 41. At this time, the unlocking portion 2211 is no longer driven by the unlocking member 31, and is locked by the first elastic member 31. The reset member 222 drives the driving member 221 to drive the unlocking portion 2211 to move to the edge of the through hole 41 and embed into the avoidance groove 42 of the unlocking member 31, thereby completing the locking of the cover body 1 and the cooker body 200 by the locking pliers 21. That is, after the unlocking member 31 and the unlocking portion 2211 complete the avoidance, the unlocking member 31 is passed through the unlocking portion 2211 by the through hole 41 and is limited by the through hole 41 without the problem of being separated from the unlocking portion 2211. It is more reliable and stable during long-term use.

[0046] Specifically, the unlocking member 31 includes a main body 311 and a supporting portion 312 disposed at the end of the main body 311. In the driving direction of the driving member 221, the supporting portion 312 protrudes from the main body 311 to form the avoidance groove 42. The avoidance groove 42 may be a slot opened at the side of the unlocking member 31, or may be a supporting portion 312 extending laterally disposed at the end of the unlocking member 31, so that the supporting portion 312 exceeds the main body 311 of the unlocking member 31 in the driving direction of the driving member 221, so that the avoidance groove 42 is formed at the side of the main body 311. In this embodiment, the structure of disposing the supporting portion 312 at the top of the main body 311 is mainly adopted.

[0047] In addition, a second elastic reset member 32 is provided between the unlocking member 31 and the cover body 1, and the second elastic reset member 32 is used to drive the unlocking member 31 to extend out of the cover body 1. It can be understood that when the cover body 1 is unlocked from the pot body 200 and the cover body 1 is removed from the pot body 200, if the unlocking structure 3 is required to work when the cover is closed next time, the unlocking member 31 needs to be extended out of the cover body 1 again. At this time, the unlocking member 31 can be extended out of the cover body 1 by manual operation, but the operation is obviously cumbersome. Therefore, in this embodiment, the second elastic reset member 32 is further provided between the unlocking member 31 and the cover body 1, so that when the cover body 1 is detached from the pot body 200, the second elastic reset member 32 can drive the unlocking member 31 to extend out of the cover body 1, so as to unlock the locking structure 2 when the cover is closed next time, without additional manual operation, which is more practical.

[0048] Specifically, the step of separating the cover body 1 from the cookware body 200 is that the user first actively releases the locking state of the locking structure 2 on the cover body 1 and the cookware body 200, that is, drives the driving member 221 to drive the locking clamp 21 to move to the disengaged position, at which time the unlocking portion 2211 moves relative to the unlocking member 31 to escape from the avoidance groove 42, and then the user can operate the cover body 1 to separate from the cookware body 200. During the disengagement process, the unlocking member 31 is driven by the second elastic return member 32 to exit the through hole 41 on the unlocking portion 2211, and the driving member 221 is driven by the first elastic return member 222 to drive the locking clamp 21 back to the locked position to restore the relative position of the unlocking member 31 and the unlocking portion 2211, so that when the cover body 1 is covered on the cookware body 200 again, the unlocking member 31 can automatically drive the unlocking portion 2211 and drive the locking clamp 21 to move to the disengaged position. It can be understood here that the user actively operates the driving member 221 to drive the locking pliers 21 to move to the disengaged position to open the cover body 1. The method can be an electric drive method, that is, the driver is driven to move by a button to achieve the above purpose. In addition, it can also be a manual drive method, that is, the driving member 221 is also provided with an operating part 2212 extending out of the cover body 1, and the user manually operates the operating part 2212 to directly drive the driving member 221 to move. The specific method is not limited here, and the above functions can be achieved based on actual product production needs. In this embodiment, the driving member 221 is mainly unlocked by manually driving the operating part 2212, which has a simple structure, low cost, and strong stability.

[0049] In addition, the unlocking portion 2211 includes a driving connecting rod 2211a fixed on the driving member 221, and a limiting structure 223 is provided between the driving member 221 and the driving connecting rod 2211a, and the limiting structure 223 is used to limit the movement of the driving connecting rod 2211a relative to the driving member 221. The unlocking portion 2211 can be formed integrally with the driving member 221, and in this embodiment, the unlocking portion 2211 and the driving member 221 are decomposed, that is, the unlocking portion 2211 is set as the driving connecting rod 2211a fixed on the driving member 221. On the one hand, the processing is more convenient on the basis of ensuring the structural strength, and on the other hand, it is easy to disassemble, maintain and replace. In order to ensure the stability of the movement of the driving connecting rod 2211a during the movement of the driving member 221, the present application also sets the limiting structure 223 between the driving connecting rod 2211a and the driving member 221.

[0050] Specifically, the limiting structure 223 can be of various types, including but not limited to a limiting hole, so that the driving connecting rod 2211a is inserted into the limiting hole, which can limit the movement of the driving connecting rod 2211a itself and ensure that it moves synchronously with the driving member 221. In this embodiment, the limiting structure 223 includes a limiting groove 223a opened on the driving member 221, and the driving connecting rod 2211a is at least partially embedded in the limiting groove 223a.

[0051] In addition, a convex rib 11 is provided on the cover body 1 at a position corresponding to the driving link 2211a, and a guide groove 111 is provided on the convex rib 11, and the driving link 2211a is at least partially placed in the guide groove 111. The driving link 2211a is partially fixed to the driving member 221, and partially extends outward. The part fixed to the driving member 221 is limited by the limiting structure 223 to ensure the stability of the activity, while the part extending outward may have the problem of activity offset or deformation, which will also affect the stability of the activity. Therefore, the present application further provides the convex rib 11 on the cover body 1, and provides the guide groove 111 at the position corresponding to the convex rib 11, so as to support and guide the activity of the driving link 2211a, and further improve its activity stability.

[0052] In addition, the cover body 1 is extended along the first direction and the second direction, the driving member 221 can be movably arranged on the cover body 1 along the first direction, and the locking pliers 21 can be movably arranged on the cover body 1 along the second direction. One of the driving member 221 and the locking pliers 21 is provided with a guide groove 5, and the other side is protruding with a guide rod 6. The guide groove 5 is arranged at a certain angle to the first direction and the second direction. The guide rod 6 extends into the guide groove 5 so that when the driving member 221 moves along the first direction, the guide rod 6 is abutted against the groove wall of the guide groove 5 to push the guide rod 6 to move along the second direction. It can be understood that the cover body 1 is generally a disc-shaped structure, that is, it extends along the first direction and the second direction, and its thickness is generally small. Therefore, the movable direction of the driving member 221 and the locking pliers 21 will not be set to the thickness direction of the cover body 1, and the locking pliers 21 need to move along the radial direction of the cover body 1 to realize its function. When there are multiple locking pliers 21 arranged along the circumference of the cover body 1, the movable direction of each locking pliers 21 is inconsistent, and the driving member 221 needs to drive multiple locking pliers 21 accordingly, that is, the driving member 221 that moves along a single direction needs to drive the locking pliers 21 in multiple movable directions to move. Therefore, a transmission structure needs to be set between the driving member 221 and the locking pliers 21 to change the driving direction to meet the above requirements. In this embodiment, a combination of the guide groove 5 and the guide rod 6 is provided between the driving member 221 and the locking pliers 21, and the extension direction of the guide groove 5 is specifically set to be different from the moving direction of the driving member 221 and the locking pliers 21, so that when the driving member 221 moves, the guide rod 6 abuts against the side wall of the guide groove 5 to realize the transmission from the moving direction of the driving member 221 to the moving direction of the locking pliers 21, and the structure is simple and practical.

It can be understood that the pot cover 100 can be movably connected to the cookware body 200 or can be independent of the cookware body 200, both of which meet the functional requirements of the present application. In this embodiment, it is mainly configured that the pot cover 100 is hinged to the cookware body 200.

[0054] Specifically, the pot body 200 is provided with a locking structure 2, and the end of the locking structure 2 is provided with a locking portion 201 extending laterally, and the locking pliers 21 and the cover body 1 clamp the locking portion 201 to lock the pot body 200 and the pot cover 100. In the present application, the pot 1000 mainly includes a pressure cooker. As is known to all, the internal pressure of the pressure cooker is relatively high, and it is necessary to ensure that the pot cover 100 and the pot body 200 are locked to prevent the pot cover 100 from moving away from the pot body 200. Therefore, in the present application, the locking pliers 21 are set to clamp the locking structure 2 with the cover body 1 to meet the locking requirements. In addition, the cookware body 200 includes an inner pot and a base. The inner pot can be fixed to the base or detachably arranged on the base. The base is mainly used for supporting and loading other structural components. The inner pot is mainly used for carrying ingredients to be cooked. Specifically, the locking structure 2 is configured as a pot edge bent outward at the port of the inner pot, and the pot edge protrudes from the end surface of the base, so that the locking clamp 21 can extend between the pot edge and the base, and clamp and lock the pot edge with the cover body 1, thereby meeting the structural and functional requirements required by this application.
