Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, and more specifically to a lid assembly and cooking equipment. Background Technology

[0002] When using cooking appliances such as pressure cookers, it is necessary to ensure that even if the user presses the lid opening button, the lid cannot be opened to prevent the porridge or water inside the pot from splashing out due to excessive pressure and causing injury.

[0003] In related technologies, some cooking functions of a pressure cooker are equipped with an anti-opening lid feature, while others are not. For example, the rice cooking function has an anti-opening lid feature, but the porridge cooking function does not. Normally, the anti-opening lid feature is only included when the cooker is in pressure cooking mode. However, if the steam channel of the pressure cooker becomes clogged due to lack of cleaning, even non-pressure cooking modes like porridge cooking may experience high pressure. Since the non-pressure cooking mode does not have an anti-opening lid feature, users are easily scalded by splashing soup when opening the lid.

[0004] To address the aforementioned issues, one type of rice cooker incorporates a stop slider and a pressure relief slider to control the opening of the lid. The stop slider's movement is controlled by a float valve, enabling a lid-opening prevention function during pressureless cooking. However, the stop slider and pressure relief slider occupy a significant amount of space, and their dispersed arrangement results in a cluttered overall layout of the cooker's lid assembly. Summary of the Invention

[0005] The present invention provides a cover assembly and a cooking device to solve the problem that the stop slider and pressure relief slider occupy a large space and the various structures are scattered, resulting in a messy overall layout of the cover assembly of the cooking device.

[0006] This invention provides a cooking device, comprising: Inner cover; The cover latch is movably connected to the inner cover and has a locking position for locking the cover assembly and an unlocking position for unlocking the cover assembly. The first push block is movably disposed on the inner cover along the first direction, and has a limiting position that cooperates with the cover opening buckle to limit the cover opening buckle to the locking position, and a separating position that separates from the cover opening buckle. A driving component, connected to the first pusher, is used to drive the first pusher to reciprocate between the limit position and the separation position; The second push block is movably disposed on the inner cover along the first direction, and has a fixed state in which it cooperates with the cover opening buckle to limit the cover opening buckle to the locked position, and an active state in which it cooperates with the cover opening buckle to move. A buoyancy element is movably disposed on the inner cover, having an upward floating position to limit the second push block in the fixed state, and an initial position to separate from the second push block; A limiting cover plate is disposed on the inner cover and forms a limiting space with the inner cover. The second push block is movably disposed within the limiting space, and at least a portion of the first push block is movably disposed within the limiting space.

[0007] Beneficial effects: By configuring the first push block, drive component, second push block, and buoyancy component, when the cooking device performs pressure cooking modes such as rice cooking, the first push block is in the limiting position that limits the lid opening latch to the locked position before pressure is released, so the user cannot open the inner lid; during the pressure release process, the buoyancy component is pushed up by the pressure inside the pot and floats to the upper position that limits the second push block, and the second push block limits the lid opening latch to the locked position, so the user cannot open the inner lid of the cooking device until the pressure inside the pot of the cooking device drops completely to atmospheric pressure level, so as to avoid the user being scalded by the soup splashed from the pot. When the cooking equipment is performing pressureless cooking modes such as porridge making, if the steam passage of the cooking equipment becomes blocked due to lack of cleaning over a long period of time, causing the pressure inside the pot to exceed atmospheric pressure during cooking, the buoyancy component is lifted by the pressure inside the pot and floats to the upper position of the limiting second push block. The second push block then limits the lid opening latch to the locked position, preventing the user from opening the inner lid of the cooking equipment until the pressure inside the pot completely drops to atmospheric pressure. This prevents the user from being scalded by splashing soup. The limiting cover plate and the inner lid form a limiting space, which limits and guides the movement of the second push block, ensuring its smooth and accurate movement and preventing it from shifting, tilting, or getting stuck. It also limits and guides the movement of the first push block, ensuring its smooth and accurate movement and preventing it from shifting, tilting, or getting stuck. Meanwhile, since the limiting cover can simultaneously limit and guide the first push block and the second push block, the first push block and the second push block, as well as the structures related to them, can be clearly and orderly distributed, saving space and resulting in a more compact, clear and orderly overall layout of the cover assembly of the cooking equipment.

[0008] In one optional embodiment, the limiting cover plate has a protruding limiting rib, the limiting rib is disposed in the limiting space and divides the limiting space into a first space and a second space, the second push block is movably disposed in the first space, and at least a portion of the first push block is movably disposed in the second space.

[0009] By setting the limiting ribs, the limiting space can be divided into a first space and a second space to limit and guide the second push block and the first push block respectively. The movement of the second push block and the first push block can be limited and guided in the moving direction, ensuring the smoothness and accuracy of the movement of the second push block and the first push block, preventing the second push block and the first push block from deviating, tilting or jamming, and also avoiding movement interference between the second push block and the first push block.

[0010] In one optional embodiment, the limiting ribs are two that are spaced apart along the second direction, and the two limiting ribs, together with the limiting cover and the inner cover, form the first space, wherein the first space is provided on at least one side of the second direction; wherein the first direction is perpendicular to the second direction.

[0011] Limiting ribs are provided on both sides of the second push block to better limit its movement and achieve better limiting and guiding effects. The limiting ribs, together with the limiting cover plate and the inner cover, form a first space, which can limit the movement of the second push block in any direction other than the direction of movement of the second push block. At least one side of the first space in the second direction has a second space. The setting of the second space is more flexible. The second space can limit and guide the movement of the first push block, ensuring the smoothness and accuracy of the movement of the first push block and preventing the first push block from deviating, tilting, or getting stuck.

[0012] In one optional embodiment, a positioning post protrudes from the side of the limiting rib facing away from the limiting cover plate, and a positioning hole is provided on the inner cover, with the positioning post being inserted into the positioning hole.

[0013] Beneficial effects: The positioning of the limiting cover and the inner cover can be achieved by inserting the positioning pin and the positioning hole, which facilitates the connection between the limiting cover and the inner cover.

[0014] In one alternative embodiment, the cooking device further includes an elastic element connected between the second push block and the inner cover, or the elastic element connected between the second push block and the limiting cover plate.

[0015] Beneficial effects: The elastic element is connected between the second push block and the inner cover, or between the second push block and the limiting cover plate. It applies an elastic force to the second push block to move and reset in the direction of the opening latch. This allows the second push block, which is in the active state, to move along with the opening latch. When the opening latch resets from the unlocked position to the locked position, it can follow the opening latch to reset to the position before the second push block moved under the action of the elastic force of the elastic element. This keeps the second push block in the position that cooperates with the opening latch.

[0016] In one optional embodiment, the limiting cover plate has a protruding connecting post, and the limiting cover plate is connected to the inner cover through the connecting post.

[0017] The connecting posts facilitate the support of the space between the inner cover and the limiting cover, thus forming a limiting space.

[0018] In one optional embodiment, the connecting post is provided with a first connecting hole, and the inner cover is provided with a corresponding second connecting hole, the first connecting hole and the second connecting hole being connected by fasteners.

[0019] Beneficial effects: The connecting post facilitates the connection between the inner cover and the limiting cover through the first connecting hole, the second connecting hole and the fastener, and also facilitates the support of the gap space in the inner cover and the limiting cover to form a limiting space.

[0020] In one optional embodiment, the first push block is provided with a limiting hole, which is a strip-shaped hole extending along the first direction, and the limiting hole is movably fitted around the outer periphery of the connecting post.

[0021] Beneficial effects: The limiting hole is movably sleeved on the outer periphery of the connecting post, and the first push block can be limited and guided by the limiting hole and the connecting post to ensure the smooth and accurate movement of the first push block; and to prevent the first push block from deviating, tilting or getting stuck.

[0022] Secondly, the present invention also provides a cooking device, including the aforementioned lid assembly and pot assembly, wherein the lid latch has a locking position for locking the lid assembly and the pot assembly, and an unlocking position for unlocking the lid assembly and the pot assembly.

[0023] In one alternative implementation, the cooking device is a rice cooker or a pressure cooker. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The following is combined Figures 1 to 15 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, in one aspect, the present invention provides a cooking device, including an inner lid 1, a lid-opening latch 2, a first push block 3, a driving assembly 4, a second push block 5, and a buoyancy member 6; the lid-opening latch 2 is movably connected to the inner lid 1, having a locking position for locking the lid assembly and an unlocking position for unlocking the lid assembly; the first push block 3 is movably disposed on the inner lid 1 along a first direction, having a limiting position for cooperating with the lid-opening latch 2 to limit the lid-opening latch 2 to the locking position, and a separating position for separating from the lid-opening latch 2; the driving assembly 4 is connected to the first push block 3, for driving the first push block 3 in the limiting position and the separating position. The second pusher 5 is movably disposed on the inner cover 1 along the first direction, having a fixed state in which it cooperates with the cover opening latch 2 to limit the cover opening latch 2 to the locked position, and an active state in which it cooperates with the cover opening latch 2 to move; the buoyancy member 6 is movably disposed on the inner cover 1, having an upward floating position in which it floats to limit the second pusher 5 to the fixed state, and an initial position in which it separates from the second pusher 5; the limiting cover plate 11 is disposed on the inner cover 1 and forms a limiting space with the inner cover 1, the second pusher 5 is movably disposed in the limiting space, and at least part of the first pusher 3 is movably disposed in the limiting space.

[0030] With the arrangement of the first push block 3, drive component 4, second push block 5, and buoyancy component 6, when the cooking device performs pressure cooking modes such as rice cooking, the first push block 3 is in the limiting position that limits the lid opening buckle 2 to the locked position before the pressure is released, so the user cannot open the lid assembly; during the pressure release process, the buoyancy component 6 is pushed up by the pressure inside the pot and floats to the floating position that limits the second push block 5, and the second push block 5 limits the lid opening buckle 2 to the locked position, so the user cannot open the lid assembly of the cooking device at this time, until the pressure inside the pot of the cooking device is completely reduced to atmospheric pressure level before the lid assembly can be opened, so as to avoid the user being scalded by the soup splashed from the pot. When the cooking equipment is performing pressureless cooking modes such as porridge making, if the steam channel 9 of the cooking equipment becomes blocked due to lack of cleaning, causing the pressure inside the pot to exceed atmospheric pressure during cooking, the buoyancy component 6 is lifted by the pressure inside the pot and floats to the upper position of the limiting second push block 5. The second push block 5 then limits the lid latch 2 to the locked position, preventing the user from opening the cooking equipment until the pressure inside the pot completely drops to atmospheric pressure, thus avoiding burns from splashed soup. The limiting cover plate 11 and the inner cover 1 form a limiting space, which limits and guides the movement of the second push block 5, ensuring its smooth and accurate movement and preventing it from shifting, tilting, or getting stuck. The limiting space also limits and guides the movement of the first push block 3, ensuring its smooth and accurate movement and preventing it from shifting, tilting, or getting stuck. Meanwhile, since the limiting cover plate 11 can simultaneously limit and guide the first push block 3 and the second push block 5, the first push block 3 and the second push block 5, as well as the structures related to them, can be clearly and orderly distributed, saving space and resulting in a more compact, clear and orderly overall layout of the cover assembly of the cooking equipment.

[0031] In one specific embodiment, when the cooking device is performing a pressure cooking mode such as rice cooking, the drive component 4 drives the first push block 3 to move to the limit position and closes the steam channel 9 on the lid assembly. At this time, the lid opening latch 2 is limited by the first push block 3 and cannot move. The lid opening latch 2 is in the locked position, and the user cannot open the lid assembly of the cooking device. When the pressure cooking mode of the cooking device is nearing the end of cooking and pressure needs to be released, the drive component 4 drives the first push block 3 to move to the separation position and opens the steam channel 9 on the inner lid 1 to release pressure. At this time, the first push block 3 separates from the lid opening latch 2 and reaches the separation position. The first push block 3 will no longer limit the lid opening latch 2. Since pressure release requires a certain amount of time... It can be completed when the pressure inside the pot of the cooking device has not completely dropped to atmospheric pressure. The buoyancy component 6 will be lifted up by the pressure inside the pot to the upper position of the second push block 5, thus limiting the second push block 5 to a fixed state. At this time, the lid opening latch 2 is limited by the second push block 5 and cannot move. The lid opening latch 2 is in the locked position, and the user cannot open the lid assembly of the cooking device. When the pressure inside the pot of the cooking device has completely dropped to atmospheric pressure, the buoyancy component 6 will move to the initial position under its own gravity. The buoyancy component 6 will separate from the second push block 5, and the second push block 5 will be in an active state, no longer limiting the lid opening latch 2. The lid opening latch 2 is in the unlocked position. At this time, pressing the lid opening latch 2 can open the lid assembly.

[0032] In another specific embodiment, when the cooking device performs a pressureless cooking mode such as porridge cooking, the drive component 4 drives the first push block 3 to move to the separation position to ensure that the steam channel 9 is open. At this time, the first push block 3 separates from the lid opening latch 2 and reaches the separation position, and the first push block 3 will no longer limit the lid opening latch 2. If the steam channel 9 of the cooking device is blocked due to long-term lack of cleaning, the pressure inside the pot in the pressureless cooking mode will be higher than atmospheric pressure, and the buoyancy component 6 will be pushed up by the pressure inside the pot and float to the limit of the second push block 5. When the second push block 5 is in the upper position, it is limited to a fixed state. At this time, the lid opening latch 2 is limited by the second push block 5 and cannot move. The lid opening latch 2 is in the locked position, and the user cannot open the lid assembly of the cooking device. When the pressure inside the pot of the cooking device drops completely to the atmospheric pressure level, the buoyancy component 6 will move to the initial position under its own gravity. The buoyancy component 6 separates from the second push block 5, and the second push block 5 is in the active state and no longer limits the lid opening latch 2. The lid opening latch 2 is in the unlocked position. At this time, pressing the lid opening latch 2 can open the lid assembly.

[0033] In one embodiment, the cooking device further includes an elastic element 7 connected between the second push block 5 and the inner cover 1.

[0034] The elastic element 7 is connected between the second push block 5 and the inner cover 1. It applies an elastic force to the second push block 5 to move and reset in the direction of the cover opening latch 2. This causes the second push block 5, which is in an active state, to move along with the cover opening latch 2. When the cover opening latch 2 resets from the unlocked position to the locked position, it can be reset to the position before the second push block 5 moved under the action of the elastic force of the elastic element 7. This keeps the second push block 5 in the position that cooperates with the cover opening latch 2.

[0035] In one embodiment, the cover assembly further includes an elastic element 7 connected between the second push block 5 and the limiting cover plate 11.

[0036] The elastic element 7 is connected between the second push block 5 and the limiting cover plate 11. It applies an elastic force to the second push block 5 to move and reset in the direction of the opening latch 2. After the second push block 5 moves with the opening latch 2, when the opening latch 2 resets from the unlocked position to the locked position, it can follow the opening latch 2 to reset to the position before the second push block 5 moved under the action of the elastic force of the elastic element 7. This keeps the second push block 5 in the position that cooperates with the opening latch 2.

[0037] In one embodiment, the limiting cover plate 11 has a protruding limiting rib 12, the limiting rib 12 is disposed in the limiting space and divides the limiting space into a first space and a second space, the second push block 5 is movably disposed in the first space, and at least part of the first push block 3 is movably disposed in the second space.

[0038] By setting the limiting rib 12, the limiting space can be divided into a first space and a second space to limit and guide the second push block 5 and the first push block 3 respectively. The movement of the second push block 5 and the first push block 3 can be limited and guided in the moving direction, ensuring the smoothness and accuracy of the movement of the second push block 5 and the first push block 3, preventing the second push block 5 and the first push block 3 from deviating, tilting or jamming, and also avoiding the second push block 5 and the first push block 3 from interfering with each other in movement.

[0039] In one specific embodiment, the limiting rib 12 is a plate-shaped structure extending along the moving direction of the second push block 5, and the second push block 5 slides in conjunction with the limiting rib 12.

[0040] By sliding the limiting rib 12 with the second push block 5, the movement of the second push block 5 can be limited and guided in the direction of movement, ensuring the smoothness and accuracy of the movement of the second push block 5; and preventing the second push block 5 from deviating, tilting or getting stuck.

[0041] In one embodiment, the limiting rib 12 has two spaced apart along the second direction, and the two limiting ribs 12 together with the limiting cover plate 11 and the inner cover 1 form the first space, and the first space is provided on at least one side of the second direction; wherein, the first direction is perpendicular to the second direction.

[0042] Two limiting ribs 12 are respectively disposed on both sides of the second push block 5 to better limit the movement of the second push block 5. Preferably, the two limiting ribs 12 slide and engage with the two sides of the second push block 5 to achieve better limiting and guiding effects. The limiting ribs 12, together with the limiting cover plate 11 and the inner cover 1, form a first space, which can limit the movement of the second push block 5 in any direction other than the direction of movement of the second push block 5. The first space has a second space on at least one side in the second direction. The setting of the second space is more flexible. The second space can limit and guide the movement of the first push block 3, ensuring the smoothness and accuracy of the movement of the first push block 3, and preventing the first push block 3 from deviating, tilting or jamming.

[0043] In a specific implementation, a second space is provided on either side of the first space in the second direction, allowing for flexible arrangement of the first push block 3 and the second push block 5. Alternatively, second spaces are provided on both sides of the first space in the second direction, enabling better guidance and positioning of more positions of the first push block 3.

[0044] In a further embodiment, a positioning post protrudes from the side of the limiting rib 12 facing away from the limiting cover plate 11, and a positioning hole is provided on the inner cover, with the positioning post being inserted into the positioning hole.

[0045] By inserting the positioning pin and positioning hole, the positioning of the limiting cover 11 and the inner cover 1 can be realized, which facilitates the connection between the limiting cover 11 and the inner cover 1.

[0046] In one embodiment, a connecting plate 13 protrudes from the limiting cover plate 11 and is disposed within the limiting space; the second push block 5 is provided with an installation groove 51, the connecting plate 13 extends into the installation groove 51, and the elastic element is connected between the connecting plate 13 and the groove wall of the installation groove 51.

[0047] The protruding connecting plate 13 can be positioned opposite to the groove wall of the mounting groove 51 to facilitate the connection of the elastic element. Through the connecting plate 13 and the groove wall of the mounting groove 51, the axial directions of both ends of the elastic element 7 can be limited and fixed respectively, so as to better limit and fix the elastic element 7.

[0048] In a specific embodiment, the mounting groove 51 has a first protrusion 52 on its groove wall, the connecting plate 13 extends into the mounting groove 51, and the connecting plate 13 has a second protrusion 131; one end of the elastic member 7 is sleeved with the first protrusion 52, and the other end is sleeved with the second protrusion 131.

[0049] The protruding connecting plate 13 can be arranged opposite to the groove wall of the mounting groove 51 so that the first protrusion 52 protrudes towards the groove wall of the mounting groove 51, and the groove wall of the mounting groove 51 protrudes towards the connecting plate 13 with the second protrusion 131. The first protrusion 52 and the second protrusion 131 can limit and fix the two ends of the elastic member 7 in the circumferential direction and the axial direction respectively, so as to better limit and fix the elastic member 7.

[0050] In a further embodiment, one end of the elastic member 7 is sleeved on the outer periphery of the first protrusion 52 and abuts against the groove wall of the mounting groove 51, and the other end is sleeved on the outer periphery of the second protrusion 131 and abuts against the connecting plate 13.

[0051] The protruding connecting plate 13 can be arranged opposite to the groove wall of the mounting groove 51, so that the first protrusion 52 protrudes towards the groove wall of the mounting groove 51, and the groove wall of the mounting groove 51 protrudes towards the connecting plate 13 with a second protrusion 131. The first protrusion 52 and the second protrusion 131 can limit and fix the two ends of the elastic member 7 in the circumferential direction, respectively. The connecting plate 13 and the groove wall of the mounting groove 51 can limit and fix the two ends of the elastic member 7 in the axial direction, respectively, so as to better limit and fix the elastic member 7.

[0052] In a specific implementation, the elastic element 7 is a spring.

[0053] In another embodiment, the first protrusion 52 is a rib with a cross-shaped cross section. Alternatively, the first protrusion 52 may also be a cylindrical structure, a frustum-shaped structure, or a rectangular strip structure. The shape of the first protrusion 52 is not explicitly limited here.

[0054] In another further embodiment, the second protrusion 131 is a rib with a cross-shaped cross section. Alternatively, the second protrusion 131 may be a cylindrical structure, a frustum-shaped structure, or a rectangular strip structure. The shape of the second protrusion 131 is not explicitly limited here.

[0055] In one embodiment, the limiting cover plate 11 is provided with a connecting post 14 protruding from it, and the limiting cover plate 11 is connected to the inner cover 1 through the connecting post 14.

[0056] By setting the connecting column 14, it is easy to support the space between the inner cover 1 and the limiting cover 11, so as to form a limiting space.

[0057] In one embodiment, the limiting cover plate 11 is provided with a connecting post 14 protruding from it, and the limiting cover plate 11 is connected to the inner cover 1 through the connecting post 14.

[0058] By setting the connecting column 14, it is easy to support the space between the inner cover 1 and the limiting cover 11, so as to form a limiting space.

[0059] In a specific embodiment, the connecting post 14 is provided with a first connecting hole 15, and the inner cover 1 is provided with a corresponding second connecting hole 16. The first connecting hole 15 and the second connecting hole 16 are connected by fasteners.

[0060] By setting the connecting post 14, it is easy for the inner cover 1 and the limiting cover 11 to be connected through the first connecting hole 15, the second connecting hole 16 and the fastener, and it is also easy to support the gap space in the inner cover 1 and the limiting cover 11 so as to form a limiting space.

[0061] In one embodiment, the first push block 3 is provided with a limiting hole 31, which is a strip-shaped hole extending along the first direction, that is, the moving direction of the first push block 3, and the limiting hole 31 is movably sleeved on the outer periphery of the connecting post 14.

[0062] The limiting hole 31 is movably sleeved on the outer periphery of the connecting post 14. The limiting hole 31 and the connecting post 14 can limit and guide the first push block 3, ensuring the smooth and accurate movement of the first push block 3 and preventing the first push block 3 from deviating, tilting or getting stuck.

[0063] In one embodiment, the first push block 3 is provided with a clearance space 34; the second push block 5 is movably disposed on the inner cover 1 and located within the clearance space 34.

[0064] Because the first push block 3 has an avoidance space 34, it can ensure that the first push block 3 and the second push block 5 will not interfere with each other when they move. It can also save space by setting them in a nested manner. Furthermore, it allows the first push block 3, the second push block 5, and the related structures to be clearly and orderly distributed, resulting in a more compact, clear, and orderly overall layout of the lid assembly of the cooking device.

[0065] In one embodiment, the first push block 3 includes a connecting part 32 and a limiting part 33; the connecting part 32 is connected to the driving component 4; one end of the limiting part 33 is connected to the connecting part 32, and the other end has the limiting position and the separation position; the limiting part 33 and the connecting part 32 form the avoidance space 34.

[0066] By setting the connecting part 32 and the limiting part 33, it is not only easy to connect with the driving component 4, but also easy to open the cover buckle 2. Furthermore, by setting the two separately, the overall structure of the first push block 3 can be simplified, and an avoidance space 34 can be formed to avoid movement interference with the second push block 5. At the same time, it can save the space occupied by the first push block 3 and the second push block 5 as a whole, and ensure the compactness of the cover assembly.

[0067] In one embodiment, there are two limiting parts 33, which are respectively disposed at both ends of the connecting part 32 and together with the connecting part 32 form an avoidance space 34, and the second push block 5 is movably disposed within the avoidance space 34.

[0068] The connecting part 32 of the first push block 3 and the two limiting parts 33 form an avoidance space 34, which can not only ensure that the first push block 3 and the second push block 5 will not interfere with each other when they move, but also save the space occupied by the first push block 3 and the second push block 5 as a whole, and ensure the compactness of the cover assembly structure; it can also limit and guide the first push block 3 from both sides of the second push block 5 to ensure the smooth movement of the second push block 5.

[0069] In one embodiment, the connecting part 32 is provided with a snap-fit ​​groove, and the connecting part 32 is detachably snapped into the driving component 4 through the snap-fit ​​groove.

[0070] The snap-fit ​​slot facilitates a detachable snap-fit ​​connection with the drive assembly 4, simplifying the connection process between the drive assembly 4 and the connecting part 32.

[0071] In a further embodiment, the limiting part 33 is provided with the limiting hole 31.

[0072] The limiting hole 31 is provided on the limiting part 33, which can not only limit and guide the first push block 3, but also increase the strength of the limiting part 33.

[0073] In a preferred embodiment, there are two limiting ribs 12, which are respectively disposed on both sides of the second push block 5 and preferably slide in cooperation with both sides of the second push block 5; two limiting parts 33 are respectively disposed on both sides of the two limiting ribs 12, so that the limiting ribs 12 can limit and guide the second push block 5 and also limit and guide the first push block 3.

[0074] In one embodiment, the second push block 5 has a driving inclined surface 53 at one end facing the cover opening buckle 2, and the driving inclined surface 53 cooperates with the cover opening buckle 2.

[0075] Due to the driving inclined surface 53, the forces applied to the second push block 5 from the cover latch 2 can be decomposed into a first component force in the direction of movement and a second component force perpendicular to the direction of movement. The second push block 5, in the active state, moves with the cover latch 2 under the action of the first component force. The second component force is limited by the limiting cover plate 11 and the inner cover 1 and will not drive the second push block 5 to move. Therefore, by setting the driving inclined surface 53, the forces applied by the cover latch 2 in various directions can be received and converted into forces that drive the second push block 5 to move.

[0076] In one embodiment, the cover-opening buckle 2 is provided with an elastic buckle 21, which cooperates with the driving inclined surface 53.

[0077] By setting the elastic buckle 21, the elastic force of the elastic buckle 21 can play a buffering role when it cooperates with the drive inclined surface 53, reducing the damage caused to each other when the cover opening buckle 2 and the second push block 5 cooperate.

[0078] In a further embodiment, the cover buckle 2 is provided with a groove, and an elastic buckle 21 is connected to the bottom of the groove. The two sides of the elastic buckle 21 are spaced apart from the two sides of the groove wall to ensure that the elastic buckle 21 has good elastic deformation capability.

[0079] In a preferred embodiment, the elastic buckle 21 is formed by bending the spring sheet upwards, with a smooth transition at the bend. The bend of the elastic buckle 21 slides in cooperation with the driving inclined surface 53 of the second push block 5, thus avoiding damage to the driving inclined surface 53.

[0080] In a further embodiment, the cover opening buckle 2 is rotatably connected to the inner cover 1.

[0081] In one embodiment, the second push block 5 is provided with a limiting groove 54 on the side facing the inner cover 1, the inner cover 1 is provided with a through hole 17, the buoyancy member 6 is movably disposed at the through hole 17, the buoyancy member 6 has the floating position where it floats and is inserted into the limiting groove 54, and the initial position where it is separated from the limiting groove 54.

[0082] When the buoyancy component 6 is inserted into the limiting groove 54, it is fixed at the through hole 17 by the buoyancy component 6, so that the second push block 5 cannot move due to the limiting effect of the buoyancy component 6, and is thus in a fixed state. The second push block 5 cannot move under the drive of the opening latch 2. When the buoyancy component 6 is separated from the limiting groove 54, the buoyancy component 6 will no longer limit the second push block 5, and the second push block 5 is in an active state and can move under the drive of the opening latch 2.

[0083] Meanwhile, the through hole 17 also limits and guides the buoyancy component 6.

[0084] In one embodiment, the cooking device further includes a seal 8, which is connected to the inner cover 1, fitted around the outer periphery of the buoyancy member 6, and covers the through hole 17.

[0085] By setting the sealing element 8, the through hole 17 can be sealed to prevent gas from escaping from the through hole 17.

[0086] In a specific embodiment, the outer periphery of the end of the buoyancy member 6 facing away from the second push block 5 is provided with an installation groove 51. The installation groove 51 is an annular groove. The sealing member 8 is a ring structure and is sleeved on the outer periphery of the buoyancy member 6. The inner ring of the sealing member 8 is inserted into the installation groove 51, and the outer ring of the sealing member 8 abuts against the side of the inner cover 1 facing away from the second push block 5.

[0087] In one embodiment, the cooking device further includes a steam channel 9 and a sealing element 10. The sealing element 10 is movably disposed on the inner cover 1 and has a sealing position for sealing the steam channel 9 and a connecting position for opening the steam channel 9. One end of the driving component 4 cooperates with the sealing element 10, and the other end is connected to the first push block 3.

[0088] The sealing component 10 has a sealing position for blocking the steam passage 9 and a connecting position for opening the steam passage 9. The driving component 4 synchronously drives the sealing component 10 and the first push block 3. When the first push block 3 reaches the limit position under the drive of the driving component 4, the sealing component 10 is in the sealing position for blocking the steam passage 9, and the cooking device is in pressure cooking mode. When the first push block 3 reaches the separation position under the drive of the driving component 4, the sealing component 10 is in the connecting position, and the cooking device begins to depressurize.

[0089] In a specific implementation, the sealing element 10 may be a steel ball.

[0090] In one embodiment, the drive assembly 4 includes a connecting rod 41 and a drive valve 42; the connecting rod 41 is movably disposed on the inner cover 1, one end of which cooperates with the sealing member 10, and the other end is connected to the first push block 3; the drive valve 42 is connected to the connecting rod 41 and is used to drive the connecting rod 41 to move along the moving direction of the first push block 3.

[0091] The connecting rod 41 moves under the drive of the drive valve 42, and drives the first push block 3 and the sealing component 10 to move.

[0092] In a specific implementation, the drive valve 42 can be a solenoid valve, and the connecting rod 41 is a solenoid valve connecting rod 41.

[0094] In one embodiment, the cooking device is a rice cooker or a pressure cooker.

[0095] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by this application.
