Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and in particular to a container lid and a cooking utensil. Background Technology

[0002] A pressure cooker is a common cooking appliance. Its main function is to increase the heating temperature by increasing the pressure inside the pot, thereby increasing the heating speed. A pressure cooker generally consists of a lid, a container body, a drive assembly, and clamps. The drive assembly is used to move the clamps relative to the container body, so that the clamps can be used to engage or disengage the lid from the container body. However, during the movement of the clamps, there is a risk that the clamps may stop at an intermediate position, causing the lid to not engage properly with the container body. Utility Model Content

[0003] This application provides a container lid and a cooking appliance to solve the problem that the clamping motion of existing pressure cookers can stop at the middle stroke position, resulting in the container lid not being able to be properly engaged with the container body.

[0004] The first aspect of this application provides a container lid, the container lid including a lid body, a clamp assembly, a drive assembly and a first elastic element, the lid body including a fixing part, the clamp assembly including at least two clamps movably connected to the lid body, the drive assembly being movably connected to the clamp assembly to drive the at least two clamps to move closer to or further away from each other, so that the clamp assembly is in a clamped state or an open state.

[0005] The first elastic element has a movable end and a fixed end. The fixed end is connected to the fixing part, and the movable end is connected to the clamp assembly. Along the radial direction of the container cap, the fixed end is located outside the movable end.

[0006] During the process of switching the clamp assembly to the open state, the first elastic element is elastically compressed. During the process of switching the clamp assembly to the clamping state, the first elastic element can drive the clamp assembly to be in the clamping state.

[0007] When the clamp assembly is in the open state, the fixing part and the clamp assembly clamp the first elastic element, that is, the fixing part and the clamp assembly restrict the fixed end and the movable end from moving away from each other, so that the first elastic element is compressed. When it is necessary to switch from the open state to the clamping state, the drive assembly is driven to move, so as to drive the clamp assembly to move away from the first elastic element along the radial direction of the container lid, so that the clamp assembly releases the restriction on the movable end to move away from the fixed end along the radial direction of the container lid, thereby allowing the first elastic element to achieve elastic rebound. That is, at this time, the movable end can push the clamp assembly to move away from the fixed end along the radial direction of the container lid, so that the two clamps automatically move closer to each other under the action of the rebound force of the first elastic element, so that the clamp assembly can automatically and quickly switch to the clamping state.

[0008] In this design, the fixed end is fixed relative to the lid, and the movable end is connected to the clamp assembly. The fixed end is located outside the movable end. When the user just drives the drive assembly to move, the rebound force of the first elastic element can make the movable end automatically drive the clamp assembly to move radially toward the center of the container lid. This allows the clamp assembly to automatically move to the clamping state, preventing the clamp from staying in the middle stroke position and causing the clamp assembly to fail to switch to the clamping state. This improves the reliability and convenience of the clamp assembly to switch smoothly to the clamping state, thereby preventing the hidden danger of the container body and container lid not being able to close properly. It also makes it easier for the user to close the container body and improves the user experience of using cooking utensils.

[0009] In this solution, the clamp assembly includes a movable component fixedly connected to the clamp, the movable end is connected to the movable component, the driving assembly includes a rotating component capable of rotating relative to the cover, the rotating component includes a driving column, the movable component is provided with a sliding groove, and during the rotation of the rotating component, the driving column can slide along the sliding groove.

[0010] In this solution, the drive assembly is equipped with a rotating component that can rotate relative to the lid. After the user drives the rotating component to rotate slightly in the first direction, the movable end of the first elastic component can provide the clamp with an acceleration that moves radially toward the center of the container lid. Without continuously applying driving force to the rotating component, the clamp assembly can automatically move to the clamping state, enabling the user to drive with less effort and improving the user experience.

[0011] In this solution, the driving component also includes a cover, which is fixedly connected to the rotating component and used to drive the rotating component to rotate. The cover facilitates the user to drive the rotating component to rotate, improving the convenience of switching the clamp component's state.

[0012] In this solution, the clamp assembly includes two clamps and two moving parts. There are two first elastic elements, and the deformation direction of the two first elastic elements is on the same straight line as the movement direction of the clamps. This reduces the risk of loss of some of the rebound force, so that the rebound force of the first elastic elements can be used to drive the clamps to move radially toward the center of the container cap. This improves the reliability and speed of the clamp assembly moving to the clamping state by the rebound force of the first elastic elements.

[0013] In this solution, the rotating component includes two driving columns, which are radially spaced along the container cover, and the two driving columns can slide along the two sliding grooves respectively.

[0014] When the line connecting the axes of the two drive columns rotates to be in the same straight line as the deformation direction of the first elastic element, the clamp assembly switches to the open state. When the line connecting the axes of the two drive columns rotates to have an angle with the deformation direction of the first elastic element, the first elastic element can drive the clamp assembly to switch to the clamping state.

[0015] In this scheme, when the line connecting the axes of the two drive columns rotates to be in the same straight line as the deformation direction of the first elastic element, the directions of the forces interacting between the fixed part, the moving part and the first elastic element are all in the same straight line and can cancel each other out and balance each other, thereby enabling the clamp assembly to be maintained in the open state and improving the reliability and stability of the clamp assembly in the open state.

[0016] When the line connecting the axes of the two drive columns rotates to form an angle with the deformation direction of the first elastic element, the movable end can drive the clamp assembly to move radially toward the center of the container lid, thereby enabling the clamp assembly to move to the clamping state on its own.

[0017] In this solution, the container lid includes a housing, the housing is fixedly connected to the lid body, the clamp assembly can be accommodated between the housing and the lid body, the movable member includes a first connecting part, the fixed part is disposed on the housing, the movable end is sleeved on the first connecting part, and the fixed end is sleeved on the fixed part.

[0018] In this design, the fixing part is set on the shell, which improves the structural tightness of the container lid and helps to reduce the volume of the container lid. At the same time, the movable end is sleeved on the first connecting part and the fixed end is sleeved on the fixing part, which improves the reliability and firmness of the connection between the first elastic element and the shell and the clamp assembly, thereby improving the reliability of the clamp assembly to smoothly switch to the open state and the clamping state.

[0019] In this design, the first connecting part includes a relatively bent connecting section and an abutting section. The movable end is sleeved on the connecting section, and the movable end can abut against the abutting section along the radial direction of the container lid.

[0020] In this design, the movable end can abut against the abutting section along the radial direction of the container lid, which helps to increase the abutting area between the first connecting part and the movable end, so that the movable end can apply a thrust to the first connecting part, so that the first elastic element can smoothly drive the clamp assembly to move toward the center of the container lid.

[0021] In this solution, the cover includes a mounting groove, the mounting groove is provided with a positioning element, and the housing includes a first mating groove and a second mating groove that are spaced apart circumferentially along the container cover.

[0022] In the open state, the positioning member is limited to the first mating groove; in the clamping state, the positioning member is limited to the second mating groove.

[0023] In this design, the positioning element engages with the first or second mating groove to limit the clamping assembly, ensuring that the clamping assembly remains stably in the open or clamped state, thus preventing the risk of accidental closing or opening due to accidental contact.

[0024] In this solution, the container lid further includes a second elastic element, and the positioning element includes a positioning part and a limiting part. The limiting part is elastically connected to the second elastic element. During the rotation of the lid, the second elastic element elastically deforms so that the positioning part can extend out of the mounting groove and engage with the first mating groove or the second mating groove.

[0025] In this design, the second elastic element can drive the positioning part to collide with the side wall and / or bottom wall of the first or second mating groove, producing a clicking sound to indicate that the clamp assembly has moved into place, thus improving the user experience.

[0026] A second aspect of this application provides a cooking utensil, the cooking utensil comprising a container body and a container lid, the container lid being used to cover the container body;

[0027] The container lid is the container lid described above.

[0028] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0082] This application provides a cooking appliance, which includes a container body and a container lid 1. The container lid 1 is used to cover the container body. The container lid 1 has a clamp 121, which can clamp the container lid 1 and the container body when the container lid 1 is connected to the container body.

[0083] In some embodiments, the specific type of cooking appliance may be a rice cooker, a multi-functional cooker, a pressure cooker, etc. This application does not limit the specific type of cooking appliance.

[0084] This application provides a container lid 1 for covering a container body, such as... Figures 1-4As shown, the container lid 1 includes a lid body 11, a clamp assembly 12, a drive assembly 13, and a first elastic member 14. The lid body 11 includes a fixing part 151. The clamp assembly 12 includes at least two clamps 121 that are movably connected to the lid body 11. The drive assembly 13 is movably connected to the clamp assembly 12 to drive the at least two clamps 121 to move closer to or further away from each other, so that the clamp assembly 12 is in a clamped state or an open state.

[0085] The first elastic element 14 has a movable end 141 and a fixed end 142. The fixed end 142 is connected to the fixing part 151, and the movable end 141 is connected to the clamp assembly 12. Along the radial direction of the container cap 1, the fixed end 142 is located outside the movable end 141.

[0086] During the process of switching the clamp assembly 12 to the open state, the first elastic element 14 is elastically compressed. During the process of switching the clamp assembly 12 to the clamping state, the first elastic element 14 can drive the clamp assembly 12 to be in the clamping state.

[0087] Specifically, when the clamp assembly 12 is in such a position Figure 5 In the open state shown, the fixing part 151 and the clamping assembly 12 are used to clamp the first elastic member 14, that is, the fixing part 151 and the clamping assembly 12 restrict the fixed end 142 and the movable end 141 from moving away from each other, so that the first elastic member 14 is compressed. When it is necessary to remove... Figure 5 The on / off state is switched to as shown. Figure 7 When the clamping state is shown, the drive assembly 13 moves to drive the clamp assembly 12 to move radially away from the first elastic member 14 along the container cover 1, so that the clamp assembly 12 releases the restriction on the movement of the movable end 141 radially away from the fixed end 142 along the container cover 1, thereby enabling the first elastic member 14 to achieve elastic rebound. That is, at this time, the movable end 141 can push the clamp assembly 12 to move radially away from the fixed end 142 along the container cover 1, so that the two clamps 121 automatically move closer to each other under the action of the rebound force of the first elastic member 14, so that the clamp assembly 12 can automatically and quickly switch to the clamping state.

[0088] Therefore, the fixed end 142 is fixed relative to the cover 11, the movable end 141 is connected to the clamp assembly 12, and the fixed end 142 is located outside the movable end 141, such as... Figure 6As shown, when the user just drives the drive assembly 13 to move, the rebound force of the first elastic element 14 can cause the movable end 141 to automatically drive the clamp assembly 12 to move radially toward the center of the container lid 1, thereby enabling the clamp assembly 12 to automatically move to the clamping state. This prevents the clamp 121 from staying in the middle stroke position, which could cause the clamp assembly 12 to fail to switch to the clamping state. This improves the reliability and convenience of the clamp assembly 12 being able to switch to the clamping state smoothly, thereby preventing the hidden danger of the container body and the container lid 1 not being properly closed, making it easier for the user to close the container body, and improving the user's experience of using cooking utensils.

[0089] Meanwhile, in the clamped state, the first elastic element 14 can still have a restoring force, that is, at this time the movable end 141 can still provide a thrust to the clamping assembly 12 to move radially toward the center of the container lid 1, reducing the risk of the clamping assemblies 12 moving away from each other due to accidental contact, and improving the reliability and stability of the clamping assembly 12 in the clamped state.

[0090] In one possible implementation, such as Figures 4-7 As shown, the clamp assembly 12 includes a movable member 122 fixedly connected to the clamp 121, and a movable end 141 connected to the movable member 122. The drive assembly 13 includes a rotating member 131 that can rotate relative to the cover 11. The rotating member 131 includes a drive column 131a. The movable member 122 is provided with a sliding groove 122a. During the rotation of the rotating member 131, the drive column 131a can slide along the sliding groove 122a.

[0091] In this embodiment, when it is necessary to extract from Figure 5 The on / off state is switched to as shown. Figure 7 In the clamping state shown, the drive rotating member 131 rotates slightly in the first direction X, so that the drive column 131a rotates in the direction away from the movable end 141. Then the movable column can drive the moving member 122 to move radially toward the center of the container cover 1. Then the first elastic member 14 elastically rebounds. At this time, the user can cancel the driving force applied to the rotating member 131. Under the pushing action of the rebound force of the movable end 141, the moving member 122 moves radially toward the center of the container cover 1, thereby moving the clamp assembly 12 to the clamping state.

[0092] Therefore, the drive assembly 13 is provided with a rotating member 131 that can rotate relative to the cover 11, so that after the user drives the rotating member 131 to rotate slightly in the first direction X, the movable end 141 of the first elastic member 14 can provide the clamp 121 with an acceleration that moves radially toward the center of the container cover 1. Without continuously applying driving force to the rotating member 131, the clamp assembly 12 can be automatically moved to the clamping state, realizing labor-saving drive for the user and improving the user experience.

[0093] In other possible implementations, the drive assembly 13 can be a drive structure capable of radial movement along the container lid 1. The drive structure is connected to the movable member 122 so that the drive structure drives the clamp 121 to move radially along the container lid 1. When the drive structure drives the clamp assembly 12 to move radially toward the center of the container lid 1, the first elastic member 14 can elastically rebound, and the movable end 141 can push the movable member 122 to drive the clamp 121 to continue moving toward the center of the container lid 1, so as to achieve automatic clamping.

[0094] In one possible implementation, such as Figure 2 and Figure 10 As shown, the drive assembly 13 also includes a cover 132, which is fixedly connected to the rotating member 131 and is used to drive the rotating member 131 to rotate.

[0095] In this embodiment, the drive assembly 13 also includes a rotating shaft 18, which can rotate relative to the cover 11. The outer wall of the cover 132 is provided with a plurality of protrusions, which are used to increase the friction force for the user to drive the cover 132 to rotate. Therefore, the cover 132 is convenient for the user to drive the rotating part 131 to rotate, thereby improving the convenience of switching states of the clamp assembly 12.

[0096] In one possible implementation, such as Figures 5-7 As shown, the clamp assembly 12 includes two clamps 121 and two moving parts 122. There are two first elastic elements 14, and the deformation direction of the two first elastic elements 14 is on the same straight line as the movement direction of the clamps 121. This ensures that the direction of the rebound force applied by the first elastic elements 14 to the clamp assembly 12 is the same as the movement direction of the clamps 121, reducing the risk of loss of some rebound force. This allows all the rebound force of the first elastic elements 14 to be used to drive the clamps 121 to move radially towards the center of the container lid 1, improving the reliability and speed of the first elastic elements 14 driving the clamp assembly 12 to the clamping state. Simultaneously, it improves the smoothness of the movement of the clamp assembly 12 radially along the container lid 1 by the first elastic elements 14.

[0097] In one possible implementation, such as Figures 5-7 As shown, the rotating component 131 includes two drive columns 131a, which are radially spaced along the container cover 1 and can slide along two slide grooves 122a respectively.

[0098] During the process of switching the clamp assembly 12 to the open state, the drive rotating member 131 rotates along the second direction Y, so that the drive column 131a rotates toward the movable end 141. The drive column 131a can abut against the side wall of the slide groove 122a, thereby driving the moving member 122 to move radially toward the fixed part 151 along the container cover 1. When the line connecting the axes of the two drive columns 131a (e.g., Figure 5 (As shown by the red dashed line) rotate to the direction of deformation of the first elastic element 14 (e.g., Figure 5 When the axes of the two drive columns 131a and the axis of the fixed part 151 are aligned on the same straight line, the clamp assembly 12 switches to the open state. That is, when the axis of the two drive columns 131a is aligned on the same straight line, the pushing force of the drive column 131a on the moving part 122 is opposite to the direction of the rebound force generated by the first elastic member 14. This push force is then applied to the movable end 141 via the moving part 122. In other words, the drive column 131a can be used to limit the elastic rebound of the first elastic member 14. This causes the pushing force and the rebound force generated by the first elastic member 14 to cancel each other out, so that the directions of the forces interacting between the fixed part 151, the moving part 122 and the first elastic member 14 are all along the same straight line and can cancel each other out and balance each other. This allows the clamp assembly 12 to be maintained in the open state, improving the reliability and stability of the clamp assembly 12 in the open state.

[0099] When the axis connecting the two drive columns 131a (e.g.) Figure 6 and Figure 7 (As shown by the red dashed line) rotate to the direction of deformation of the first elastic element 14 (e.g., Figure 6 and Figure 7 When there is an angle between the two (as shown by the light blue dashed line), the first elastic element 14 can drive the clamp assembly 12 to switch to the clamping state.

[0100] During the process of switching the clamp assembly 12 to the clamping state, the drive rotating member 131 rotates along the first direction X, so that the drive column 131a rotates away from the movable end 141. The drive column 131a can abut against the side wall of the slide groove 122a, thereby driving the moving member 122 to move radially away from the fixed part 151 along the container cover 1, that is, as Figure 6 As shown, when the line connecting the axes of the two drive columns 131a rotates to form an angle with the deformation direction of the first elastic member 14, the pushing force of the drive column 131a on the moving member 122 is in the same direction as the rebound force generated by the first elastic member 14. This allows the rebound force of the first elastic member 14 to assist the rotating member 131 in continuing to move towards the first direction X until the clamp assembly 12 is in the position shown. Figure 7 The clamping state is shown. Therefore, when the line connecting the axes of the two drive columns 131a rotates to form an angle with the deformation direction of the first elastic member 14, the movable end 141 can drive the clamp assembly 12 to move radially toward the center of the container cover 1, thereby enabling the clamp assembly 12 to move to the clamping state on its own.

[0101] It should be noted that the first direction X and the second direction Y mentioned in this article can be referenced. Figure 5 and Figure 7In one specific embodiment of the shown example, the first direction X can be clockwise and the second direction Y can be counterclockwise.

[0102] In one possible implementation, such as Figure 2 , Figure 4 and Figure 10 As shown, the container lid 1 includes a housing 15, which is fixedly connected to the lid body 11. The clamp assembly 12 can be accommodated between the housing 15 and the lid body 11. The movable part 122 includes a first connecting part 122b, a fixed part 151 disposed on the housing 15, a movable end 141 sleeved on the first connecting part 122b, and a fixed end 142 sleeved on the fixed part 151.

[0103] In this embodiment, the fixing part 151 is disposed on the housing 15, which improves the structural tightness of the container lid 1 and helps to reduce the volume of the container lid 1. At the same time, the movable end 141 is sleeved on the first connecting part 122b, and the fixed end 142 is sleeved on the fixing part 151, which improves the reliability and firmness of the connection between the first elastic member 14 and the housing 15 and the clamp assembly 12, thereby improving the reliability of the clamp assembly 12 in smoothly switching to the open state and the clamping state.

[0104] In one possible implementation, such as Figure 4 As shown, the first connecting part 122b includes a connecting section 122b1 and an abutting section 122b2 that are relatively bent. The movable end 141 is sleeved on the connecting section 122b1, and the movable end 141 can abut against the abutting section 122b2 in the radial direction of the container cover 1.

[0105] In this embodiment, the movable end 141 can abut against the abutting section 122b2 along the radial direction of the container cover 1, which helps to increase the abutting area between the first connecting part 122b and the movable end 141, so that the movable end 141 can apply a thrust to the first connecting part 122b, so that the first elastic member 14 can smoothly drive the clamp assembly 12 to move toward the center of the container cover 1.

[0106] In one possible implementation, such as Figure 8 , Figure 9 and Figure 11 As shown, the cover 132 includes a mounting groove 132a, and the mounting groove 132a is provided with a positioning element 16. The housing 15 includes a first mating groove 152 and a second mating groove 153 distributed circumferentially along the container cover 1.

[0107] In the open state, the positioning element 16 is engaged with the first mating groove 152; in the clamped state, the positioning element 16 is engaged with the second mating groove 153.

[0108] In this embodiment, the positioning member 16 engages with the first mating groove 152 or the second mating groove 153 to limit the clamping assembly 12, ensuring that it remains stably in the open or clamped state and preventing the risk of accidental closing or opening due to accidental contact. Simultaneously, the switching engagement of the positioning member 16 between the first and second mating grooves 152 and 153 improves the user's tactile feedback when switching the clamping assembly 12 to different states.

[0109] In one possible implementation, such as Figure 9 As shown, the container lid 1 also includes a second elastic member 17, and the positioning member 16 includes a positioning part 161 and a limiting part 162. The limiting part 162 is elastically connected to the second elastic member 17. During the rotation of the lid 132, the second elastic member 17 elastically deforms so that the positioning part 161 can extend out of the mounting groove 132a and be limited and engaged with the first mating groove 152 or the second mating groove 153.

[0110] In this embodiment, the second elastic element 17 can drive the positioning part 161 to collide with the side wall and / or bottom wall of the first mating groove 152 or the second mating groove 153, making a clicking sound to indicate that the clamp assembly 12 has moved into place, thus improving the user experience.

[0111] In one possible implementation, such as Figure 9 As shown, along the thickness direction of the container lid 1, the outer wall of the end of the positioning part 161 facing the housing 15 is an arc surface, which improves the smoothness of the user driving the lid head 132 to rotate, and at the same time reduces the risk of wear caused by the positioning part 161 colliding with the side wall and / or bottom wall of the first mating groove 152 or the second mating groove 153, thus improving its service life.

[0112] In one possible implementation, such as Figure 8 and Figure 11 As shown, the housing 15 includes a guide groove 154, and the cover 132 includes a sliding part 132b. The sliding part 132b can slide along the guide groove 154, and the sliding part 132b is provided with an avoidance notch 132b1.

[0113] In this embodiment, the sliding part 132b passes through the guide groove 154. During the rotation of the cover 132, the sliding part 132b can slide along the guide groove 154, thereby guiding the sliding part 132b and increasing the stability of the movement of the rotating member 131. In addition, when the clamp assembly 12 is in the clamping state, the clearance notch 132b1 is used to avoid the moving member 122, preventing the moving member 122 from obstructing the movement of the sliding member and improving the feasibility of switching the clamp assembly 12 to the clamping state.

[0114] In one possible implementation, such as Figure 3As shown, the cover 11 is provided with a protruding post 111, and the movable part 122 is provided with a sliding hole 122e. The protruding post 111 is located in the sliding hole 122e and can slide along the sliding hole 122e.

[0115] When the clamp assembly 12 switches between the clamping state and the open state, the moving part 122 drives the clamp 121 to move radially along the container cover 1. During this process, the protruding post 111 can slide in the sliding hole 122e, thereby guiding the moving part 122 through the protruding post 111 and improving the reliability of the clamp 121 moving radially along the container cover 1.

[0116] like Figures 2-7 As shown, the specific working process of container lid 1 in this embodiment is as follows:

[0117] When switching to the open state, the drive cap 132 drives the rotating member 131 to rotate in the second direction Y, so that the drive column 131a rotates toward the movable end 141. The drive column 131a can abut against the side wall of the slide groove 122a, thereby driving the moving member 122 to move radially toward the fixed part 151 along the container cap 1. When the line connecting the axes of the two drive columns 131a (e.g., Figure 5 (As shown by the red dashed line) rotate to the direction of deformation of the first elastic element 14 (e.g., Figure 5 When the two halves (shown by the light blue dashed line) are on the same straight line, and the first elastic element 14 is compressed, the clamp assembly 12 switches to the position shown by the light blue dashed line. Figure 5 As shown in the open state, under the action of the positioning member 16 and the first mating groove 152, the clamp assembly 12 can remain in the open state.

[0118] When switching to the clamping state is required, the drive cap head 132 drives the rotating member 131 to rotate along the first direction X, so that the drive column 131a rotates away from the movable end 141. When the line connecting the axes of the two drive columns 131a rotates to form an angle with the deformation direction of the first elastic member 14, the drive column 131a can abut against the side wall of the slide groove 122a, thereby driving the moving member 122 to move radially away from the fixed part 151 of the container cap 1. This allows the rebound force of the first elastic member 14 to push the moving member 122 to continue moving radially toward the center of the container cap 1, while the movement drives the rotating member 131 to continue moving toward the first direction X until the clamping assembly 12 is in the clamping position. Figure 7 As shown in the clamping state, under the action of the positioning member 16 and the second mating groove 153, the clamping assembly 12 can further maintain the clamping state.

[0119] In one possible implementation, such as Figure 2 and Figure 7As shown, the container cover 1 is also provided with a stop valve 19, and the moving part 122 is provided with an interconnected clearance hole 122c and a limiting hole 122d. The diameter of the clearance hole 122c is larger than that of the limiting hole 122d, and the clearance hole 122c is further away from the center of the container cover 1 than the limiting hole 122d.

[0120] In the clamped state, the check valve 19 is located in the clearance hole 122c, allowing the check valve 19 to move along the height direction of the container lid 1 to release pressure, which helps improve the safety of using the cooking appliance. In the open state, the check valve 19 is located in the limiting hole 122d, restricting the movement of the check valve 19 along the height direction of the container lid 1.
