Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a container lid and a cooking container. Background Technology
[0002] With the increasing popularity and development of cooking containers, users have raised demands for ease of opening the lids. Currently, cooking containers such as pressure cookers require the lid to be rotated and then lifted before it can be opened, which is a complicated process and affects the user experience. Utility Model Content
[0003] This application provides a container lid and a cooking container to simplify the opening process of the cooking container.
[0004] A first aspect of this application provides a container lid, the container lid comprising:
[0005] Cover;
[0006] The main body is mounted on the cover.
[0007] A driving member, which is capable of moving relative to the body along the height direction of the container lid, and the driving member has a first mating surface;
[0008] At least two pushers, at least one of which is movably mounted to the body, and the pusher has a second mating surface;
[0009] At least two locking elements are connected to the corresponding pushing element;
[0010] During the movement of the driving member along the height direction of the container lid, the first mating surface and the second mating surface can slide together to drive the pushing member to move the locking member along the radial direction of the container lid, so that the locking member is in the locked position or the unlocked position.
[0011] In this solution, the container lid can switch the movement of the driving component along the height direction to the radial movement of the pushing and locking components. This allows the locking component to be switched between the locked and unlocked positions using only the driving and pushing components, simplifying the container lid's structure. Furthermore, the container lid of this embodiment improves the convenience of using the cooking container, thereby enhancing the user experience.
[0012] In one possible implementation, the first mating surface includes a first arc surface, and the second mating surface includes a second arc surface. During the movement of the driving member along the height direction of the container lid, the first arc surface and the second arc surface slide together.
[0013] In this design, the stress distribution of the arc-shaped structure is more uniform when under stress, resulting in stronger structural stability and resistance to deformation. Furthermore, when the driving component moves along the height direction, the sliding fit between the first and second mating surfaces, being arc-shaped, reduces wear during relative sliding, thereby increasing the service life of the driving and pushing components.
[0014] In addition, in the high-temperature environment of cooking containers, the arc-shaped structure can better adapt to the heat accumulation environment, disperse the load in multiple directions, and extend the service life of the cooking container.
[0015] In one possible implementation, the first mating surface further includes a first limiting surface connected to the first arc surface, and the second mating surface further includes a second limiting surface connected to the second arc surface. When the locking member is in the locking position, the first limiting surface abuts against the second limiting surface.
[0016] In this solution, the contact between the first limiting surface and the second limiting surface can limit the driving member in the radial direction of the container lid, preventing the driving member from moving radially along the container lid, so that the driving member can move stably in the height direction of the container lid. This allows the movement of the driving member in the height direction to be converted into the movement of the pushing member in the radial direction, thereby improving the reliability of the locking member's movement between the locked and unlocked positions.
[0017] In one possible implementation, the drive member has mating protrusions at both ends along the radial direction of the container lid, a first mating surface is disposed on the mating protrusion, the push member has a mating groove at one end along the radial direction of the container lid near the drive member, a second mating surface is disposed on the mating groove, and at least a portion of the mating protrusion can be located within the mating groove.
[0018] In this design, a convex-concave interlocking structure is used to mate the protrusion and the groove, allowing the protrusion to occupy the space within the groove, thus helping to reduce the overall size of the container lid. Furthermore, the sliding of the protrusion along the groove restricts the direction of movement, thereby achieving precise guidance and motion control transmission between the driving and pushing components.
[0019] In one possible implementation, the container lid further includes an elastic element, one end of which abuts against the pusher and the other end of which abuts against the body.
[0020] In this solution, by setting up an elastic element, the locking element can be automatically locked without manual operation, simplifying the operation and further improving the user experience.
[0021] In one possible implementation, the pusher further includes a receiving cavity, the body having an extension extending into the receiving cavity, the elastic member being located within the receiving cavity, with one end of the elastic member connected to the extension and the other end connected to the sidewall of the receiving cavity.
[0022] In this design, the extension provides stable support for the compression and rebound of the elastic element. The receiving cavity provides space for the elastic element and eliminates the need for the elastic element to occupy space other than the pushing element, further reducing the volume of the container lid.
[0023] In one possible implementation, the body includes a base and a top plate detachably connected by a first connector, and a pusher is located between the base and the top plate, the pusher having a through hole extending radially along the container lid, the through hole being used to avoid the first connector.
[0024] In addition, the locking member and the pushing member are detachably connected via a second connector, and the base has a clearance portion on the side away from the driving member, which is used to avoid the second connector.
[0025] In this design, the base and top plate are detachably connected by the first connector, which encloses the pusher inside the main body, avoiding the risk of wear and tear on the exposed pusher material and the entry of dust and other dirt, thus ensuring normal cooperation between the pusher, the drive, and the locking components.
[0026] Furthermore, during the radial movement of the pusher along the container lid, a through hole is provided to avoid interference with the movement of the first connecting member, which is fixedly connected to the main body. The base has a clearance portion to avoid the second connecting member, ensuring a stable connection between the pusher and the locking member.
[0027] In one possible implementation, one of the main body and the driving member is provided with a limiting protrusion, and the other is provided with a limiting slot. When the locking member is in the locked position, the limiting protrusion engages with the limiting slot to restrict the radial movement of the driving member along the container lid.
[0028] In this design, the cooperation of the limiting protrusion and the limiting slot can limit the drive component in the radial direction of the container lid, so that the drive component can move stably along the height direction of the container lid.
[0029] In one possible implementation, the body further includes a first handle, and the drive member has a second handle located within the space enclosed by the first handle.
[0030] In this design, the second handle is located within the space enclosed by the first handle, thereby protecting the second handle through the first handle and preventing the locking mechanism from being mis-locked due to accidental contact with the second handle.
[0031] In addition, when a user needs to lift the container lid using the first handle, while grasping the first handle, a driving force can be applied to the second handle, causing the driving component to move along the height direction of the container lid. This, in turn, drives the pushing component and the locking component to move radially along the container lid, thereby causing the locking component 5 to engage and lock the container body, thus achieving one-click opening, reducing the number of steps required to open the lid, and improving the user experience.
[0032] A second aspect of this application provides a cooking container, comprising a container body and a container lid, the container lid being fitted onto the container body. The container lid is any of the container lids described above.
[0033] When the locking member is in the locked position, it can cooperate with the container body; when the locking member is in the unlocked position, it can release its cooperation with the container body.
[0034] In this solution, the opening and closing of the lid of the cooking container is controlled by switching the locking and unlocking positions of the locking component. This ensures the sealing of the cooking container during use, simplifies the opening process, and improves the user experience.
[0035] 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

[0075] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0076] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0077] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0078] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0079] In one specific embodiment, this application provides a cooking container, which includes a container body and a container lid. The container lid is fitted onto the container body to ensure the airtightness of the container body. The cooking container can be a pressure cooker, a micro-pressure cooker, or other similar cookware; this application does not specifically limit the type of cooking container.
[0080] The following description uses a pressure cooker as an example of a cooking container.
[0081] In one specific embodiment, such as Figure 1 and Figure 6As shown, the container lid includes a lid body 1, a main body 2, a driving member 3, at least two pushing members 4, and at least two locking members 5. The lid body 1 is used to close onto the opening of the container main body, and the main body 2 is mounted on the lid body 1. The driving member 3 is movable relative to the main body 2 along the height direction of the container lid, and the driving member 3 has a first mating surface 311. At least one pushing member 4 is movably mounted on the main body 2, and the driving member 3 also has a first mating surface 311. At least two locking members 5 are correspondingly connected to the pushing members 4.
[0082] like Figure 5 and Figure 6 As shown, during the movement of the driving member 3 along the height direction of the container lid, the first mating surface 311 and the second mating surface 411 can slide together to drive the pushing member 4 to move the locking member 5 along the radial direction of the container lid, so that the locking member 5 is in the locked position or the unlocked position.
[0083] refer to Figure 6 As shown, the driving component 3 is mounted on the main body 2. The driving component 3 can move relative to the main body 2 along the height direction of the container lid. Specifically, the driving component 3 can move closer to or further away from the main body 2, that is, with... Figure 2 and Figure 6 From the perspective shown, the drive member 3 can move upward or downward. The push member 4 is movably mounted on the main body 2, and the push member 4 can move radially relative to the main body 2, so as to... Figure 6 From the perspective shown, the pusher 4 can move to the left or to the right.
[0084] During the movement of the driving member 3 along the height direction of the container lid, the first mating surface 311 of the driving member 3 and the second mating surface 411 of the pushing member 4 can slide together. Specifically, as the driving member 3 moves closer to or further away from the main body 2, the pushing member 4 can move radially relative to the main body 2 along the container lid, and the pushing member 4 can drive the locking member 5 connected to it to move radially along the container lid, so that the locking member 5 is in the locked position or the unlocked position.
[0085] In this embodiment, the container lid can switch the movement of the driving member 3 along the height direction to the movement of the pushing member 4 and the locking member 5 along the radial direction. Thus, the locking member 5 can be switched between the locked and unlocked positions simply by using the driving member 3 and the pushing member 4, making the structure of the container lid simple.
[0086] When the container lid is closed onto the container body, the locking member 5 moves inward towards the inside of the container lid under the action of the pushing member 4, thus locking the locking member 5 in the locked position. The locking member 5 approaches and connects to the container body, locking the container body and the container lid together, thereby sealing the cooking cavity formed by the container body and the container lid, improving cooking efficiency. When the locking member 5 moves outward towards the outside of the container lid under the action of the pushing member 3, it moves into the unlocked position, releasing the connection between the locking member 5 and the container body, allowing the user to open the lid. Therefore, the container lid of this embodiment improves the convenience of using the cooking container, thereby enhancing the user experience.
[0087] In some embodiments, such as Figure 2 and Figure 3 As shown, the locking member 5 can be connected to the container body by snapping the locking member into the container body to restrict the relative movement of the container body and the container lid along the height direction. In other embodiments, the locking member 5 and the cooking body can also be locked in other ways. This application does not limit the specific locking method between the locking member 5 and the cooking body.
[0088] In one specific embodiment, reference is made to... Figure 7 As shown, the first mating surface 311 includes a first arc surface 311a, and the second mating surface 411 includes a second arc surface 411a. During the movement of the driving member 3 along the height direction of the container lid, the first arc surface 311a and the second arc surface 411a slide together.
[0089] In this embodiment, reference Figure 7 As shown, the first mating surface 311 and the second mating surface 411 slide together via an arc-shaped contact. Under stress, the arc-shaped structure provides a more uniform stress distribution, resulting in stronger structural stability and resistance to deformation. Furthermore, when the driving component 3 moves along the height direction, the arc-shaped sliding contact between the first mating surface 311 and the second mating surface 411 reduces wear during relative sliding, thus extending the service life of both the driving component 3 and the pushing component 4. Additionally, in the high-temperature environment of cooking containers, the arc-shaped structure better adapts to heat accumulation, disperses multi-directional loads, and extends the service life of the cooking container.
[0090] In one specific embodiment, reference is made to... Figure 7 As shown, the first mating surface 311 may also include a first limiting surface 311b connected to the first arc surface 311a, and the second mating surface 411 may also include a second limiting surface 411b connected to the second arc surface 411a. When the locking member 5 is in the locked position, the first limiting surface 311b abuts against the second limiting surface 411b.
[0091] In this embodiment, the contact between the first limiting surface 311b and the second limiting surface 411b can limit the drive member 3 in the radial direction of the container lid, preventing the drive member 3 from moving radially along the container lid, so that the drive member 3 can move stably in the height direction of the container lid. This allows the movement of the drive member 3 in the height direction to be converted into the movement of the push member 4 in the radial direction, thereby improving the reliability of the movement of the locking member 5 between the locked position and the unlocked position.
[0092] Specifically, the first limiting surface 311b and the second limiting surface 411b extend along the height direction of the container lid, respectively.
[0093] In other embodiments, the first mating surface 311 and the second mating surface 411 may also be inclined surfaces that can abut against each other. The inclined surfaces can convert the movement of the drive member along the height direction into the movement of the push member along the radial direction, and the inclined surfaces have the advantage of being easy to process.
[0094] In one specific embodiment, reference is made to... Figure 7 As shown, the drive member 3 has mating protrusions 31 at both ends along the radial direction of the container lid, and a first mating surface 311 is disposed on the mating protrusions 31. (Reference) Figure 9 As shown, the pusher 4 has a mating groove 41 at one end of the container lid that is radially close to the drive member 3, and a second mating surface 411 is disposed in the mating groove 41. At least a portion of the mating protrusion 31 can be located within the mating groove 41.
[0095] In this embodiment, reference Figure 7 and Figure 9 As shown, the first mating surface 311 of the driving member 3 and the second mating surface 411 of the pushing member 4 are located within the mating protrusion 31 and the mating groove 41, respectively, so that at least a portion of the mating protrusion 31 can mate with the mating groove 41. By providing a concave-convex interlocking structure in which the mating protrusion 31 and the mating groove 41 mate, the mating protrusion 31 can occupy the space within the mating groove 41, thereby helping to reduce the overall size of the container lid. On the other hand, the sliding of the mating protrusion 31 along the mating groove 41 can limit the direction of movement, thereby achieving precise guidance and motion control transmission between the driving member 3 and the pushing member 4.
[0096] In one specific embodiment, reference is made to... Figure 6 As shown, the container lid may also include an elastic element 6, one end of which abuts against the pusher 4 along the radial direction of the container lid, and the other end of which abuts against the body 2. Specifically, the elastic element 6 may be a spring.
[0097] In this embodiment, reference Figure 6 and Figure 8As shown, when the user drives the driving component 3 to move along the height direction of the container lid, the driving component 3 can drive the pushing component 4 to move radially outward. The pushing component 4 and the main body 2 can compress the elastic element. When the pushing component 4 drives the locking component 5 to the unlocked position, the compression of the elastic element 6 is at its maximum. When the driving force acting on the driving component 3 is released, under the action of the elastic force of the elastic element 6, the pushing component 4 and the locking component 5 connected to the pushing component 4 can be pushed radially inward, so that the pushing component 4 drives the locking component 5 to automatically return to the locked position. Therefore, in this embodiment, by setting the elastic element 6, the locking component 5 can be automatically in the locked position without the need for manual driving of the locking component 5 to the locked position, simplifying the operation steps and further improving the user experience.
[0098] In one specific embodiment, reference is made to... Figure 9 As shown, the pusher 4 may also include a receiving cavity 42. (Reference) Figure 11 As shown, the main body 2 has an extension 211 extending into the receiving cavity 42. (Reference) Figure 6 and Figure 8 As shown, the elastic member 6 is located inside the receiving cavity 42, and one end of the elastic member 6 is connected to the extension 211, while the other end is connected to the side wall of the receiving cavity 42.
[0099] In this embodiment, reference Figure 8 and Figure 11 As shown, the base 21 of the main body 2 has an extension 211 extending into the receiving cavity 42, which provides stable support for the compression and rebound of the elastic member 6. (Reference) Figure 6 and Figure 9 As shown, the pusher 4 is provided with a receiving cavity 42, which provides a place for the elastic member 6 and eliminates the need for the elastic member 6 to occupy space outside the pusher 4, further reducing the volume of the container lid.
[0100] refer to Figure 6 As shown, the elastic element 6 is located within the receiving cavity 42 of the pusher 4. One end of the elastic element 6 is connected to the extension 211, and the other end is connected to the side wall of the receiving cavity 42. During the radial movement of the pusher 4 along the container lid, the extension 211 remains fixed relative to the container lid. The side wall of the receiving cavity 42 moves outward in the radial direction of the container lid as the drive 3 moves. The movement of the side wall of the receiving cavity 42 exerts radial pressure on the elastic element 6, providing stored force for the reset of the elastic element 6.
[0101] In one specific embodiment, reference is made to... Figure 6 As shown, the main body 2 includes a base 21 and a top plate 22, which are detachably connected by a first connector 7, and a pusher 4 is located between the base 21 and the top plate 22. (Reference) Figure 10As shown, the pusher 4 has a through hole 43 extending radially along the container lid, the through hole 43 for circumventing the first connector 7, and the locking member 5 is detachably connected to the pusher 4 via a second connector 8. (Reference) Figure 11 As shown, the base 21 has a clearance portion 212 on the side away from the drive member 3, which is used to clear the second connector 8.
[0102] In this embodiment, reference Figure 6 As shown, the base 21 and the top plate 22 are detachably connected by the first connector 7, and the pusher 4 is located within the space enclosed between the base 21 and the top plate 22. The detachable connection between the base 21 and the top plate 22 by the first connector 7 encloses the pusher 4 inside the main body 2, avoiding the risk of wear and tear on the exposed material of the pusher 4 and the entry of dust and other dirt, thus ensuring normal cooperation between the pusher 4, the drive member 3, and the locking member 5.
[0103] refer to Figure 8 and Figure 10 As shown, the pusher 4 has a through hole 43 extending radially along the container lid, which is used to avoid the first connecting member 7. During the radial movement of the pusher 4 along the container lid, the through hole 43 avoids the first connecting member 7, which is fixedly connected to the main body 2, thus preventing interference with the movement of the pusher 4. (Reference) Figure 11 As shown, the base 21 has a clearance portion 212 for avoiding the second connector 8, which ensures a stable connection between the pusher 4 and the locking member 5.
[0104] In this embodiment, the through hole 43 can be a long strip hole, and the clearance part 212 can be an open groove along the movement direction of the pusher 4.
[0105] Specifically, the first connector 7 and the second connector 8 can be screws. In other embodiments, the first connector 7 and the second connector 8 can also be other types of connections. This application does not limit the specific structure of the first connector 7 and the second connector 8.
[0106] In other embodiments, the clearance portion 212 may also be other shapes, such as an inverted trapezoid, a V-shape, etc. This application does not limit the specific shape of the clearance portion 212.
[0107] In one specific embodiment, reference is made to... Figure 6 As shown, one of the main body 2 and the driving component 3 is provided with a limiting protrusion 213 and the other is provided with a limiting groove 32. When the locking component 5 is in the locking position, the limiting protrusion 213 and the limiting groove 32 are engaged to restrict the driving component 3 from moving radially along the container lid.
[0108] In this embodiment, reference Figure 6 and Figure 11As shown, the base 21 of the main body 2 is provided with a limiting protrusion 213, and the driving component 3 is provided with a limiting slot 32. The cooperation of the limiting protrusion 213 and the limiting slot 32 can limit the driving component 3 in the radial direction of the container lid, so that the driving component 3 can move stably along the height direction of the container lid.
[0109] In other embodiments, a limiting slot 32 may be provided on the base 21 of the main body 2, and a limiting protrusion 213 may be provided on the driving component 3. This application does not limit the specific positions of the limiting slot 32 and the limiting protrusion 213.
[0110] In one specific embodiment, reference is made to... Figure 6 As shown, the main body 2 also includes a first handle 23, and the driving component 3 has a second handle 33, which is located within the space enclosed by the first handle 23.
[0111] In this embodiment, reference Figure 6 As shown, the first handle 23 and the second handle 33 have the same shape, and the second handle 33 is located within the space enclosed by the first handle 23. This allows the first handle 23 to protect the second handle 33 and prevent accidental activation of the locking element 5. Furthermore, when the user needs to lift the container lid using the first handle 23, a driving force can be applied to the second handle 33 while gripping the first handle 23. This causes the driving element 3 to move along the height direction of the container lid, which in turn drives the pushing element 4 and the locking element 5 to move radially along the container lid. This causes the locking element 5 to engage and lock the container body, enabling one-button opening, reducing the number of steps required to open the lid, and improving the user experience.

Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application.
