[0001] The present application relates to the technical field of kitchen utensils, and particularly relates to a pressure cooker lid and a pressure cooker. Background Art

[0002] A pressure cooker is a common cooking utensil, and its main function is to increase the heating temperature by increasing the air pressure inside the pot, thereby improving the heating speed. A pressure cooker mainly consists of a pressure cooker lid and a pot body. A clamp is formed between the pressure cooker lid and the pot body, and the clamp can move relative to the pot body to simultaneously clamp or unclamp the pressure cooker lid and the pot body. However, the existing clamp device has a complex structure, resulting in a relatively large weight of the pressure cooker lid and affecting the use experience of the pressure cooker. Utility Model Content

[0003] The present application provides a pressure cooker lid and a pressure cooker to simplify the overall structure of the clamp device, reduce the overall weight of the pressure cooker lid, and improve the use experience of the pressure cooker.

[0004] In a first aspect of the present application, a pressure cooker lid is provided, which includes a lid body and a clamp device that are detachably connected. The clamp device includes:

[0005] A support member stacked above the lid body, and a connecting post is provided at the edge of the support member;

[0006] At least two clamps are provided at the edge of the support member and can slide radially along the lid body. The clamp is provided with a connecting groove, and the extending direction of the connecting groove is parallel to the moving direction of the clamp. The connecting post passes through the connecting groove and stops at the side of the clamp facing away from the support member;

[0007] A driving assembly connects the support member and the clamp to drive the clamp to move radially along the lid body.

[0008] The pressure cooker lid provided by the present application includes a lid body and a clamp device that are detachably connected. The clamp device includes a support member, at least two clamps, and a driving assembly. The support member is stacked above the lid body. The clamps are provided at the edge of the support member and can slide radially along the lid body to achieve clamping and unclamping. The driving assembly connects the support member and the clamp to drive the clamp to move radially along the lid body, so as to change the position of the clamp and switch the state of the clamp as needed. A connecting post is provided at the edge of the support member, and the clamp is provided with a connecting groove. The extending direction of the connecting groove is parallel to the moving direction of the clamp. The connecting post passes through the connecting groove and stops at the side of the clamp facing away from the support member. The same connecting post simultaneously plays a guiding role and a connecting role for the clamp, which can simplify the overall structure of the clamp device, reduce the overall weight of the pressure cooker lid, and improve the use experience of the pressure cooker.

[0009] Optionally, the driving assembly includes: a connecting rod connected to the clamp and extending in a direction close to the axis of the cover body, with a first transmission part provided at one end of the connecting rod close to the axis of the cover body; a driving member rotatably connected to the support member, the driving member being provided with a second transmission part corresponding to each connecting rod, and the second transmission part cooperating with the first transmission part to convert the rotational movement of the driving member into the radial movement of the connecting rod and the clamp. By providing the connecting rod, the radial dimension requirements of the pot lid can be met. When the user rotates the driving member, the radial movement of the clamp can be realized, which can avoid the accidental loosening of the clamp due to external force impact and other factors during use, and improve the safety of using the pressure cooker.

[0010] Optionally, an extension part is provided at the edge of the clamp, and the extension part extends along the axial direction of the cover body, and the connecting rod is connected to the extension part. The connecting rod and the extension part are arranged substantially perpendicular to each other, so that the connecting rod can only generate a radial force on the clamp, but not an axial force, which improves the smoothness of the movement of the clamp and prevents accidents such as jamming of the clamp.

[0011] Optionally, the extension part is provided with a first through hole, and a threaded section is provided at one end of the connecting rod far from the axis of the cover body. Two threaded fasteners are connected to the threaded section; the threaded section passes through the first through hole, and the two threaded fasteners are clamped on both sides of the extension part. On the one hand, the two threaded fasteners are clamped on both sides of the extension part, which can ensure that the connecting rod is stably and reliably fixed to the clamp; on the other hand, the two threaded fasteners move synchronously along the axial direction of the cover body, which can adjust the effective length of the connecting rod, so that the clamp device can be applicable to lids of various different diameters, and improve the versatility of the clamp device.

[0012] Optionally, the pressure cooker lid further includes a pressure relief valve, which passes through the cover body and can rise or fall along the cover body; the pressure relief valve is located below the driving member, and a limiting part is convexly provided at the bottom of the driving member, and a relief space is formed on one side of the limiting part along the circumference of the driving member; when the clamp is tightened, the relief space is located above the pressure relief valve, and the pressure relief valve can freely rise to form a sealed state, so that the pressure in the pot can rise to meet the normal cooking requirements; when the clamp is released, the limiting part stops above the pressure relief valve, and the pressure relief valve cannot rise and remains in a pressure relief state to prevent the pressure in the pot from rising when the pressure cooker lid is not tightly closed, ensuring the safety of using the pressure cooker.

[0013] Optionally, the first transmission part is a convex pin, and the second transmission part is a chute; along the direction away from the axis of the driving member, the chute includes a first end point, a separation point, and a second end point; when the convex pin moves between the first end point and the separation point, the clamp can be clamped or unclamped, ensuring that the edge of the cover body is within the clamping space of the clamp, preventing the clamp from being damaged by external forces, and ensuring the safe use of the clamp; when the convex pin moves between the second end point and the separation point, the clamp device can be installed and disassembled, ensuring that the edge of the cover body is completely outside the clamping space of the clamp, avoiding interference or collision between the clamp and the edge of the cover body during the disassembly process, and ensuring the smooth installation and disassembly of the clamp device.

[0014] Optionally, the pressure cooker lid further includes: a support sleeve, the support sleeve axially passes through the support member along the cover body, one end of the support sleeve abuts against the cover body, and the other end extends into the interior of the driving member; a bolt, the bolt sequentially passes through the cover body and the support sleeve and is connected to the driving member. On the one hand, the driving member is directly connected to the cover body. When the user lifts the pressure cooker lid through the driving member, the support member is not stressed, preventing the support member from being deformed or damaged; on the other hand, the support sleeve plays an axial limiting role, leaving a gap between the driving member and the support member, so that the driving member can rotate freely.

[0015] Optionally, the connecting column is threadedly connected to the support member. On the one hand, the connecting column and the support member form a detachable connection, which can facilitate the disassembly, repair or cleaning of the clamp, improving the convenience of using the clamp device; on the other hand, the connecting column can be installed axially through the connecting groove by itself, without setting a special installation port at the end of the connecting groove, keeping the connecting groove in a complete structure with a circumferentially closed and uniform width, improving the reliability of the clamp connection.

[0016] Optionally, the clamp is provided with two connecting grooves, the two connecting grooves are symmetrically arranged, and the connecting columns and the connecting grooves are arranged in one-to-one correspondence. The support member is provided with two connecting columns corresponding to each clamp, so that each clamp forms two sets of parallel guiding fits, making the force on the clamp more uniform, increasing the smoothness of the clamp movement, and preventing the clamp from swinging abnormally from side to side.

[0017] In the second aspect of the present application, a pressure cooker is provided, which includes a pot body and any pressure cooker lid provided by the present application. When the pressure cooker lid is connected to the pot body, the clamp device can simultaneously clamp the pressure cooker lid and the pot body. The present application simplifies the overall structure of the clamp device, reduces the overall weight of the pressure cooker lid, and improves the user experience of the pressure cooker by using the same connecting column to guide and connect the clamp at the same time.

[0018] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The accompanying drawings here are incorporated into the specification and form a part of this specification, showing embodiments in line with this application, and are used together with the specification to explain the principles of this application. Detailed implementation manners

[0052] In order to make the purpose, technical solutions and advantages of this application clearer and more understandable, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0053] In the description of this application, unless otherwise clearly specified and defined, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" means two or more; terms such as "connection" and "fixation" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0054] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of this application are described from the angles shown in the drawings, and should not be construed as limitations on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0055] As Figures 1 - 8 shown, the embodiments of this application provide a pressure cooker lid that can be closed on a pot body and form a pressure cooker together with the pot body. The pressure cooker lid includes a detachable cover body 1 and a clamp device 2. For example, the clamp device 2 can be connected to the cover body 1 by means of screws or buckles. The clamp device 2 includes a support member 21, at least two clamps 22, and a drive assembly 23. The support member 21 is stacked above the cover body 1. The support member 21 forms the main body part of the clamp device 2, and other components of the clamp device 2 are all installed on the support member 21, so that the clamp device 2 can be used as a whole and is detachably connected to the cover body 1. Thus, disassembly, assembly, cleaning, and maintenance are facilitated. The clamps 22 are arranged at the edge of the support member 21 and can slide radially along the cover body 1 to achieve clamping and releasing of clamping. The drive assembly 23 connects the support member 21 and the clamps 22 to drive the clamps 22 to move radially along the cover body 1, so as to change the position of the clamps 22 as needed and switch the state of the clamps 22.

[0056] Furthermore, connection posts 211 are provided at the edge of the support member 21, and connection grooves 221 are provided on the clamps 22. The extending direction of the connection grooves 221 is parallel to the movement direction of the clamps 22. The connection posts 211 pass through the connection grooves 221, and the connection posts 211 are in sliding fit with the connection grooves 221, thereby guiding the clamps 22 and ensuring that the clamps 22 can slide radially along the cover body 1. The connection posts 211 stop on the side of the clamps 22 facing away from the support member 21. The connection posts 211 play a role of axial support and limitation for the clamps 22, so that the clamps 22 and the support member 21 are connected to form a whole, preventing the clamps 22 from separating from the support member 21. By using the same connection posts 211 to play a guiding role and a connecting role at the same time, the overall structure of the clamp device 2 can be simplified, the overall weight of the pressure cooker lid can be reduced, and the use experience of the pressure cooker can be improved.

[0057] Specifically, the support member 21 is arranged in a shell-like structure with an opening downward, and the connection posts 211 protrude from the bottom of the support member 21. The clamps 22 are stacked below the support member 21, which can not only make a part of the clamps 22 be received inside the support member 21 to improve the appearance of the clamp device 2, but also make the clamps 22 be clamped between the cover body 1 and the support member 21 to improve the stability of the movement of the clamps 22 and the reliability of clamping.

[0058] Among them, the connecting column 211 includes a guiding section and a stopping section. The cross-section of the stopping section is larger than that of the guiding section, and the stopping section is farther from the support member 21 relative to the guiding section. The guiding section passes through the connecting groove 221 and is slidably matched with the connecting groove 221, so as to guide the movement of the clamp 22; the stopping section stops on the side of the clamp 22 away from the support member 21, so that the clamp 22 is clamped between the support member 21 and the stopping section.

[0059] Furthermore, the connecting column 211 is threadedly connected to the support member 21. On the one hand, the connecting column 211 and the support member 21 form a detachable connection, which can facilitate the disassembly, repair or cleaning of the clamp 22 and improve the convenience of using the clamp device 2; on the other hand, the connecting column 211 can be installed through the connecting groove 221 along its own axis, without setting a special installation opening at the end of the connecting groove 221, so that the connecting groove 221 maintains a circumferentially closed and uniformly wide complete structure, improving the reliability of the connection of the clamp 22. It can be understood that in other embodiments, the connecting column 211 can also be connected to the support member 21 by non-detachable means such as welding or integral molding.

[0060] Furthermore, the clamp 22 is provided with two connecting grooves 221, and the two connecting grooves 221 are arranged at intervals along the extending direction of the clamp 22, and the two connecting grooves 221 are symmetrically arranged with each other. The connecting column 211 and the connecting groove 221 are arranged in one-to-one correspondence. That is to say, the support member 21 is provided with two connecting columns 211 corresponding to each clamp 22, so that each clamp 22 forms two groups of parallel guiding fits, so that the force on the clamp 22 is more uniform, increasing the smoothness of the movement of the clamp 22 and preventing abnormal conditions such as left and right swinging of the clamp 22. It can be understood that in other embodiments, only one connecting groove 221 can be provided, or multiple connecting grooves 221 can be provided.

[0061] Further, the driving assembly 23 includes a connecting rod 231 and a driving member 232. The connecting rod 231 is connected to the clamp 22 and extends in a direction close to the axis of the cover body 1 to meet the radial dimension requirements of the pot lid. A first transmission portion 2311 is provided at one end of the connecting rod 231 close to the axis of the cover body 1. The driving member 232 can be used as the cover head of the pressure cooker lid. The driving member 232 is stacked above the support member 21 and is rotatably connected to the support member 21 to facilitate the user to hold and rotate the driving member 232. The driving member 232 is provided with a second transmission portion 2321 corresponding to each connecting rod 231. The second transmission portion 2321 extends below the support member 21, and the second transmission portion 2321 cooperates with the first transmission portion 2311 to convert the rotational movement of the driving member 232 into the radial movement of the connecting rod 231 and the clamp 22; the cooperation between the first transmission portion 2311 and the second transmission portion 2321 can, for example, adopt a gear-rack mechanism, a pulley or a crank-connecting rod 231 mechanism, etc., any mechanism that can convert rotational movement into linear movement. When the user rotates the driving member 232 to achieve the radial movement of the clamp 22, it can avoid accidental loosening of the clamp 22 due to external force impact and other factors during use, improving the safety of using the pressure cooker.

[0062] Further, an extension portion 222 is provided at the inner edge of the clamp 22. The extension portion 222 extends along the axial direction of the cover body 1. The connecting rod 231 is connected to the extension portion 222, and the connecting rod 231 is disposed substantially perpendicular to the extension portion 222, so that the connecting rod 231 can only generate a radial force on the clamp 22 and does not generate an axial force, improving the smoothness of the movement of the clamp 22 and preventing accidents such as jamming of the clamp 22.

[0063] Further, the extension portion 222 is provided with a first through hole. A threaded section 2312 is provided at one end of the connecting rod 231 away from the axis of the cover body 1. Two threaded fasteners 2313 are connected to the threaded section 2312. The threaded section 2312 passes through the first through hole, and the two threaded fasteners 2313 are clamped on both sides of the extension portion 222. On the one hand, the two threaded fasteners 2313 are clamped on both sides of the extension portion 222, which can ensure that the connecting rod 231 is stably and reliably fixed to the clamp 22; on the other hand, the two threaded fasteners 2313 move synchronously along the axial direction of the cover body 1, which can adjust the effective length of the connecting rod 231, so that the clamp device 2 can be applicable to cover bodies 1 of various different diameters, improving the versatility of the clamp device 2.

[0064] Further, the support member 21 is provided with a convex block 212. The convex block 212 is provided with a second through hole. The connecting rod 231 passes through the second through hole. The connecting rod 231 is supported and guided through the second through hole to ensure that the connecting rod 231 can only move radially along the cover body 1, preventing the connecting rod 231 from shaking or swinging during the movement process.

[0065] Further, the pressure cooker lid further includes a support sleeve 4 and a bolt 5. The support sleeve 4 axially penetrates the support member 21 along the axis of the lid body 1. One end of the support sleeve 4 abuts against the lid body 1, and the other end extends into the interior of the driving member 232. The bolt 5 sequentially penetrates the lid body 1 and the support sleeve 4 and is connected to the driving member 232. On the one hand, the driving member 232 is directly connected to the lid body 1. When the user lifts the pressure cooker lid through the driving member 232, the support member 21 is not stressed, preventing the support member 21 from being deformed or damaged. On the other hand, the support sleeve 4 plays an axial limiting role, leaving a gap between the driving member 232 and the support member 21, so that the driving member 232 can rotate freely.

[0066] Further, the pressure cooker lid further includes a pressure relief valve 3. The pressure relief valve 3 penetrates the lid body 1 and can move up and down along the lid body 1. The pressure relief valve 3 is located below the driving member 232. A limiting portion 2322 is convexly provided at the bottom of the driving member 232. An avoidance space 2323 is formed on one side of the limiting portion 2322 along the circumference of the driving member 232. When the clamp 22 is clamped, the avoidance space 2323 is located above the pressure relief valve 3, and the pressure relief valve 3 can rise freely to form a sealed state, so that the pressure in the pot can rise to meet the normal cooking requirements. When the clamping of the clamp 22 is cancelled, the limiting portion 2322 stops above the pressure relief valve 3, and the pressure relief valve 3 cannot rise and remains in a pressure relief state to prevent the pressure in the pot from rising when the pressure cooker lid is not tightly closed, ensuring the safe use of the pressure cooker.

[0067] In one embodiment, the first transmission portion 2311 is a convex pin, and the second transmission portion 2321 is a sliding groove. The convex pin is slidably engaged with the sliding groove to convert the rotational motion of the driving member 232 into the radial movement of the connecting rod 231 and the clamp 22, enabling the clamp 22 to clamp or cancel the clamping. Setting the convex pin on the connecting rod 231 can keep the force-bearing position of the connecting rod 231 basically unchanged, increasing the smoothness of the operation of the connecting rod 231. It can be understood that in other embodiments, the first transmission portion 2311 can be a sliding groove, and the second transmission portion 2321 can be a convex pin.

[0068] Further, the sliding groove is provided at the edge of the driving member 232 and extends toward one side along the tangential direction of the driving member 232. This can not only simplify the structure of the sliding groove and the production process but also increase the actual rotation angle of the driving member 232 as much as possible to achieve labor-saving operation.

[0069] Further, the driving member 232 has a first rotation stroke and a second rotation stroke. The first rotation stroke is the use stroke, and the second rotation stroke is the disassembly stroke. Along the direction away from the driving member 232, the sliding groove includes a first end point 2321a, a separation point 2321b, and a second end point 2321c. During the first rotation stroke (refer to Figure 6 and Figure 7), the convex pin is located between the first end point 2321a and the separation point 2321b. The clamp 22 can be clamped or unclamped. That is to say, in the section where the clamp 22 is close to the axis of the cover body 1, the edge of the cover body 1 is located within the clamping space of the clamp 22, preventing the clamp 22 from being damaged by external forces and ensuring the safe use of the clamp 22. In the second rotation stroke (refer to Figure 7 and Figure 8 ), the convex pin is located between the second end point 2321c and the separation point 2321b. The clamp device 2 can be installed and disassembled. That is to say, in the section where the clamp 22 is far from the axis of the cover body 1, the edge of the cover body 1 is completely located outside the clamping space of the clamp 22, avoiding interference or collision between the clamp 22 and the edge of the cover body 1 during the disassembly process and ensuring the smooth installation and disassembly of the clamp device 2.

[0070] Furthermore, the driving member 232 is provided with an elastic locking member (not shown in the figure), and the support member 21 is provided with a locking groove. The elastic locking member is engaged with or disengaged from the locking groove to lock or release the driving member 232, so that the clamp 22 can be stably stopped at the expected position. For example, the clamp 22 can be stably stopped at the clamping position, the unclamping position or the disassembly position, etc., preventing the clamp 22 from moving freely and causing the clamp 22 to fail to achieve the expected function.

[0071] In addition, the embodiment of the present application also provides a pressure cooker, which includes a pressure cooker lid and a pot body, and the pressure cooker lid is detachably connected to the pot body. When the pressure cooker lid is connected to the pot body, the clamp device 2 can simultaneously clamp the pressure cooker lid and the pot body, thereby realizing the reliable connection between the pressure cooker lid and the pot body.

[0072] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
