Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooking utensils, in particular to a container cover and a cooking container. BACKGROUND

[0002] The cooking utensil such as pressure cooker is a commonly used cooking container in people's daily life. Generally, the cover of the pressure cooker is provided with a clamp, and the clamp is used to control the opening and closing of the cover and the body. In use, the user needs to unlock the clamp through an unlocking button, so that the cover can be separated from the body. When the cover is closed on the body, the locking button needs to be locked again, which is relatively inconvenient to operate. CONTENT OF THE UTILITY MODEL

[0003] The present application relates to a container cover and a cooking container, which can reduce the unlocking difficulty of the clamp.

[0004] The present application provides a container cover, which comprises:

[0005] a cover body;

[0006] a clamp installed on the cover body;

[0007] a driving part installed on the cover body, used to drive the clamp to move relative to the cover body, so as to lock or unlock the cover body;

[0008] wherein the driving part comprises a moving part, a rotating part and a reset part, the clamp has a matching part, the moving part can move along the thickness direction of the container cover, is used to drive the rotating part to rotate, the matching part is matched with the rotating part, and the reset part is connected with the moving part and is used to drive the moving part to reset;

[0009] When the moving part moves in a first direction, the moving part drives the rotating part to rotate, and the rotating part can drive the clamp to unlock the cover body through the matching part;

[0010] the reset part is used to drive the moving part to move in a second direction opposite to the first direction, when the moving part moves in the second direction, the moving part drives the rotating part to rotate, and the rotating part can drive the clamp to lock the cover body through the matching part.

[0011] In the scheme provided by the present application, the clamp can be controlled through the cooperation of the rotating part and the matching part, so as to lock or unlock the cover body. In operation, the user only needs to drive the moving part to move, which is relatively simple to operate, and the overall structure of the driving part is relatively simple, which can reduce the assembly difficulty and is conducive to improving the production efficiency.

[0012] In one possible implementation, the rotating part is a gear, the mating part is a rack, the moving part is provided with a tooth structure, and the rotating part meshes with the tooth structure and the mating part.

[0013] This design allows for the formation of a rack and pinion transmission structure between the moving part and the rotating part, and between the rotating part and the mating part. Rack and pinion transmissions have advantages such as high transmission accuracy, high transmission stability, and high transmission efficiency. Moreover, through the rack and pinion connection, rotational and linear displacement can be converted, making the overall structure more compact and better suited to practical application requirements.

[0014] In one possible implementation, the rotating part includes a first gear part and at least one second gear part, the first gear part meshing with the moving part, and the second gear part meshing with the mating part;

[0015] Along the axial direction of the first gear portion, at least one end of the first gear portion is provided with a second gear portion, and the diameter of the pitch circle of the first gear portion is different from the diameter of the pitch circle of the second gear portion.

[0016] This design allows for adjustment of the transmission ratio, thereby regulating the opening and closing speed of the clamps and better meeting actual usage needs.

[0017] In one possible implementation, the container lid includes at least two clamps, each clamp having two mating parts, the number of rotating parts being the same as the number of clamps, and each rotating part including two second gear parts;

[0018] When the moving part moves in the first direction, each of the clamps can move away from each other radially along the container lid;

[0019] When the moving part moves in the second direction, each of the clamps can move closer to each other in the radial direction of the container lid.

[0020] By incorporating at least two clamps, the stability of the locking cover can be improved. Each clamp has at least two mating parts, increasing the contact area between the clamp and the rotating part, thereby enhancing the stability of the clamp's movement and better meeting practical usage requirements.

[0021] In one possible implementation, the movable part includes a body and an extension, the extension extending along the thickness direction of the container cap, at least a portion of the body being disposed circumferentially along the extension and having a gap with the extension, the reset member being a first elastic member, the reset member being sleeved with the extension, and at least a portion of the reset member being located in the gap.

[0022] This design allows the reset component to be sleeved with the moving part, thereby improving the stability of the connection between them. When an external force drives the moving part to move, the reset component can undergo elastic deformation, and the restoring force generated by the reset component can act on the moving part. When the external force applied to the moving part is removed, the restoring force of the reset component can drive the moving part to move, so that the moving part is reset.

[0023] In one possible implementation, the container lid includes a housing and a mounting portion, the housing and / or the mounting portion being connected to the lid body, and the drive portion being mounted on the housing and / or the mounting portion;

[0024] Along the thickness direction of the container lid, the clamp is located between the housing and the mounting part, and the housing is connected to the mounting part for clamping the clamp.

[0025] This design integrates the drive unit and clamps through the housing and mounting section, allowing them to form a module. During assembly, the housing, mounting section, drive unit, and clamps can be assembled into a module first, and then the module can be installed as a whole onto the lid, making installation more convenient. Furthermore, when cleaning the container lid, the module can be completely removed, cleaned, and then reinstalled.

[0026] In one possible implementation, the mounting portion is located on the side of the clamp facing the cover, and a second elastic member is provided on the side of the mounting portion facing the clamp. One end of the second elastic member is connected to the mounting portion, and the other end is connected to the clamp. The mating portion is located on the side of the clamp away from the mounting portion.

[0027] By incorporating a second elastic element, a force can be applied to the clamp, causing it to tend to move towards the side where the rotating part is located. This improves the stability of the engagement between the mating and rotating parts. Since the second elastic element can undergo elastic deformation, the force between it and the clamp can be controlled within a suitable range. This enhances the stability of the engagement between the mating and rotating parts while preventing excessive force that could affect the clamp's movement during locking and unlocking.

[0028] In one possible implementation, a rolling element is provided at one end of the second elastic member facing the clamp, and the second elastic member abuts against the clamp through the rolling element.

[0029] Since the clamp moves relative to the mounting part during locking and unlocking, the contact between the second elastic element and the clamp can be made rolling by setting a rolling element, thereby reducing the friction between the second elastic element and the clamp and reducing the interference of the second elastic element on the movement of the clamp.

[0030] In one possible implementation, the housing is provided with a first through hole, the movable part is provided with a second through hole, the first through hole and the second through hole are in communication, and the container lid includes a limiting member, part of which is located in the first through hole and part of which is located in the second through hole, for limiting the range of movement of the movable part along the thickness direction of the container lid.

[0031] Such a limiting component can limit the movement of the part, thereby restricting the possibility of the part detaching from the container lid.

[0032] This application embodiment also provides a cooking container, the cooking container comprising:

[0033] Container body;

[0034] A container lid that can be closed onto the container body;

[0035] Wherein, the container lid is any of the container lids described above.

[0036] This application provides a container lid and a cooking container. The container lid includes a lid body, clamps, and a driving part. The clamps and driving part are mounted on the lid body. The driving part drives the clamps to move relative to the lid body to lock or unlock the container lid. The driving part includes a moving part, a rotating part, and a resetting part. The clamps are provided with a mating part. The moving part can move along the thickness direction of the container lid to drive the rotating part to rotate. The mating part can engage with the rotating part. When the rotating part rotates, the rotating part can drive the mating part to move so that the clamps can lock or unlock the lid body. When the moving part moves in a first direction, the clamps unlock the lid body. The resetting part can drive the moving part to move in a second direction, driving the moving part to reset. When the moving part moves in the second direction, the rotating part drives the clamps to lock the lid body through the mating part. This design reduces the difficulty of unlocking, facilitates user operation, simplifies the structure, and improves production efficiency. Attached Figure Description

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] like Figure 1 As shown, this application embodiment provides a container lid that can cover the container body 8. As... Figure 2 As shown, the container lid includes a lid body 1, a clamp 2, and a drive unit 3. The clamp 2 and the drive unit 3 are directly or indirectly mounted on the lid body 1. The drive unit 3 drives the clamp 2 to move relative to the lid body 1, so that the clamp 2 can lock or unlock the container lid. The drive unit 3 includes a moving part 31, a rotating part 32, and a resetting part 33. The clamp 2 is provided with a mating part 21. The moving part 31 can move along the thickness direction of the container lid to drive the rotating part 32 to rotate. The mating part 21 can cooperate with the rotating part 32. When the rotating part 32 rotates, the rotating part 32 can drive the mating part 21 to move, which in turn can drive the clamp 2 to move relative to the lid body 1, so that the clamp 2 can lock or unlock the lid body 1. In use, an external force can be applied to the moving part 31 to drive the moving part 31 to move along a first direction. When the moving part 31 moves along the first direction, the moving part 31 drives the rotating part 32 to rotate, so that the mating part 21 drives the clamp 2 to unlock the lid body 1. When the external force is removed, the reset member 33 can drive the moving part 31 to move in a second direction opposite to the first direction, thereby driving the moving part 31 to reset. When the moving part 31 moves in the second direction, the moving part 31 drives the rotating part 32 to rotate. At this time, the rotation direction of the rotating part 32 is opposite to the rotation direction of the rotating part 32 when the moving part 31 moves in the first direction. Therefore, the movement direction of the mating part 21 is also opposite to that during unlocking, so that the rotating part 32 can drive the clamp 2 to lock the cover 1 through the mating part 21.

[0068] In the solution provided in this application embodiment, the clamp 2 can be controlled by the cooperation of the rotating part and the mating part 21 to lock or unlock the cover 1. During operation, the user only needs to drive the moving part 31 to move, which is relatively simple. Moreover, the overall structure of the driving part 3 is relatively simple, which can reduce the assembly difficulty and improve production efficiency.

[0069] Meanwhile, the solution provided in this application embodiment can automatically reset the clamp 2 by driving the moving part 31 through the reset member 33. Therefore, the user only needs to drive the moving part 31 during the unlocking process, and no operation is required during the reset. Compared with solutions that have unlock and lock buttons, this design can reduce the possibility of accidental touch by the user.

[0070] like Figure 3 As shown, in one possible implementation, the rotating part 32 is a gear, the mating part 21 is a rack, and the moving part 31 is provided with a gear tooth structure. The rotating part 32 can simultaneously mesh with both the gear tooth structure and the mating part 21.

[0071] This design allows for the formation of a gear and rack transmission structure between the moving part 31 and the rotating part, and between the rotating part and the mating part 21. Gear and rack transmission has advantages such as high transmission accuracy, high transmission stability, and high transmission efficiency. Moreover, through gear and rack engagement, rotational and linear displacement can be converted, making the overall structure more compact and better suited to actual usage requirements.

[0072] like Figure 2 As shown, in one possible embodiment, the rotating part 32 includes a first gear part 321 and at least one second gear part 322. The first gear part 321 is used to mesh with the moving part 31, and the second gear part 322 is used to mesh with the mating part 21. Along the axial direction of the first gear part 321, at least one end of the first gear part 321 is provided with the second gear part 322, and the pitch circle diameter of the first gear part 321 and the pitch circle diameter of the second gear part 322 are different. The rotating part 32 can be mounted via a rotating shaft.

[0073] This design allows for adjustment of the transmission ratio, thereby regulating the opening and closing speed of clamp 2, which better meets actual usage requirements.

[0074] The transmission ratio can be adjusted by adjusting the structure of the first gear section 321 and the second gear section 322, thereby adjusting the formation of the moving section 31 and the magnitude of the force required for the clamp 2 to move.

[0075] like Figure 2 As shown, in one possible implementation, the diameter of the pitch circle of the second gear portion 322 is larger than the diameter of the pitch circle of the first gear portion 321.

[0076] This design reduces the displacement distance required by the moving part 31 when the clamp 2 moves, making it easier for the rotating part 32 to drive the mating part 21 and reducing the difficulty of operation.

[0077] like Figure 2As shown, in one possible embodiment, the container lid includes at least two clamps 2 and at least two rotating parts 32, the number of rotating parts 32 being the same as the number of clamps 2. Each clamp 2 is provided with two engaging parts 21, and each rotating part 32 is provided with two second gear parts 322, with each clamp 2 engaging with its corresponding rotating part 32. When the moving part 31 moves along a first direction, each clamp 2 can move away from each other radially along the container lid to unlock the lid 1. When the moving part 31 moves along a second direction, each clamp 2 can move closer to each other radially along the container lid. The first direction can be a direction approaching the lid 1 along the thickness direction of the container lid, and the second direction can be a direction away from the lid 1 along the thickness direction of the container lid.

[0078] By providing at least two clamps 2, the stability of the locking cover 1 can be improved. Each clamp 2 is provided with at least two mating parts 21, which increases the mating area between the clamp 2 and the rotating part 32, thereby improving the stability of the clamp 2's movement and better meeting actual usage requirements.

[0079] During use, when the user needs to unlock the cover 1, they can drive the moving part 31 to move relative to the cover 1 by pressing or other means, thereby driving the clamp 2 to unlock the cover 1. After unlocking, the user can remove the external force, and the reset member 33 drives the moving part 31 to reset, thereby driving the clamp 2 to reset and put it in the locked state.

[0080] By providing second gear portions 322 on opposite sides of the first gear portion 321, the thickness of the rotating portion 32 can be increased, thereby improving the structural strength of the rotating portion 32.

[0081] like Figure 3 As shown, in one possible embodiment, the movable part 31 includes a body part 311 and an extension part 312. The extension part 312 extends along the thickness direction of the container lid. At least a portion of the body part 311 is disposed circumferentially along the extension part 312. A gap exists between the body part 311 and the extension part 312. The reset member 33 is a first elastic member, which may be a spring or the like. The reset member 33 is sleeved with the extension part 312, and at least a portion of the reset member 33 is located in the gap between the body part 311 and the extension part 312.

[0082] This design allows the reset member 33 to be sleeved with the moving part 31, thereby improving the stability of the connection between the reset member 33 and the moving part 31. When an external force drives the moving part 31 to move, the reset member 33 can undergo elastic deformation, and the restoring force generated by the reset member 33 can act on the moving part 31. When the external force applied to the moving part 31 is removed, the restoring force of the reset member 33 can drive the moving part 31 to move, so that the moving part 31 is reset.

[0083] like Figure 3As shown, in one possible embodiment, the container lid includes a housing 4 and a mounting portion 5, the housing 4 and / or the mounting portion 5 being connected to the lid body 1, and a drive portion 3 being mounted on the lid body 1 and / or the mounting portion 5. A reinforcement is located between the housing 4 and the mounting portion 5 along the thickness direction of the container lid. The housing 4 and the mounting portion 5 are connected for clamping a clamp 2 to restrict the direction of movement of the clamp 2; typically, the clamp 2 can only move radially along the container lid.

[0084] This design integrates the drive unit 3 and the clamp 2 through the housing 4 and the mounting part 5, allowing them to form a module. During assembly, the housing 4, mounting part 5, drive unit 3, and clamp 2 can be assembled into a module, which is then installed onto the cover 1 as a whole, making installation more convenient. Furthermore, when cleaning the container cover, the module can be completely removed, and after cleaning the cover 1, it can be reinstalled onto the cover 1.

[0085] like Figure 2 and Figure 3 As shown, in one possible embodiment, the mounting part 5 is located on the side of the clamp 2 facing the cover 1. A second elastic member 51 is provided on the side of the mounting part 5 facing the clamp 2. One end of the second elastic member 51 is connected to the mounting part 5, and the other end is connected to the clamp 2. The mating part 21 is located on the side of the clamp 2 away from the mounting part 5, that is, the second elastic member 51 and the mating part 21 are located on opposite sides of the clamp 2. The side of the clamp 2 away from the mounting part 5 is used to mate with the rotating part 32.

[0086] By providing the second elastic element 51, a force can be applied to the clamp 2, causing the clamp 2 to tend to move towards the side where the rotating part 32 is located. This helps to improve the stability of the engagement between the mating part 21 and the rotating part 32. Since the second elastic element 51 can undergo elastic deformation, the force between the second elastic element 51 and the clamp 2 can be controlled within a suitable range. This improves the stability of the engagement between the mating part 21 and the rotating part 32 while preventing the force between the mating part 21 and the rotating part 32 from becoming too large, which would affect the movement of the clamp 2 during locking and unlocking.

[0087] By providing a second elastic element 51, the impact of the gap caused by the assembly error of the mating part 21 and the rotating part 32 can be reduced, thereby improving the stability of the meshing.

[0088] like Figure 2 As shown, in one possible implementation, a rolling element 52 is provided at one end of the second elastic member 51 facing the clamp 2, and the second elastic member 51 abuts against the clamp 2 through the rolling element 52.

[0089] Since the clamp 2 moves relative to the mounting part 5 during locking and unlocking, the rolling element 52 can be set to make the contact between the second elastic element 51 and the clamp 2 a rolling contact, thereby reducing the friction between the second elastic element 51 and the clamp 2, and thus reducing the interference of the second elastic element 51 on the movement of the clamp 2.

[0090] like Figure 3 As shown, in one possible embodiment, the housing 4 is provided with a first through hole 41, and the moving part 31 is provided with a second through hole 313, the first through hole 41 and the second through hole 313 communicating with each other. The container lid may also include a limiting member 6, part of which is located in the first through hole 41 and part of which is located in the second through hole 313. The limiting member 6 is used to limit the range of movement of the moving part 31 along the thickness direction of the container lid.

[0091] The limiting member 6 can limit the movement of the moving part 31, thereby restricting the possibility of the moving part 31 detaching from the container lid.

[0092] like Figure 3 As shown, in one possible implementation, the housing 4 can be sleeved on the outside of the movable part 31 and has two first through holes 41 arranged radially along the container lid. The first through holes 41 are located on opposite sides of the movable part 31. The limiting member 6 can be a rod-shaped structure, with its opposite ends located in the first through holes 41 and its middle located in the second through hole 313.

[0093] like Figure 4 As shown, in one possible implementation, the container lid may include a cap 7, which may be mounted on the housing 4, and a movable part 31 is connected to the cap 7. In use, the user can drive the movable part 31 to unlock the lid 1 by using the cap 7.

[0094] like Figure 4 As shown, in one possible implementation, the container lid may include a cap 7, which can be fitted onto the housing 4, with a portion of the housing 4 extending into the interior of the cap 7. When the user needs to remove the container lid, they can first press down on the cap 7 to drive the moving part 31 to move, thereby driving the clamp 2 to unlock the lid 1. Applying pressure inward from the side of the cap 7 increases the friction between the cap 7 and the housing 4, thereby keeping the cap 7 and the housing 4 relatively stationary, thus keeping the clamp 2 in the open state, and allowing the container lid to be removed from the cooking container.

[0095] In one possible implementation, the container lid may include a cap 7, which may be mounted on the housing 4. The cap 7 may have a third through hole, and at least a portion of the movable part 31 is located in the third through hole and is movable relative to the cap 7. In use, the user can apply force to the movable part 31 with their fingers while picking up the cap 7 to drive the movable part 31 to move, thereby driving the clamp 2 to unlock the cap 7.

[0096] In the solution provided in this application embodiment, the user can unlock the clamp 2 by driving the moving part 31 to move in the direction close to the lid 1; that is, when unlocking, the moving part 31 moves downward along the direction of gravity. Compared with the solution of unlocking the clamp 2 by driving the moving part 31 upward, the downward movement of the moving part 31 can improve the stability of unlocking. When the unlocking method is to drive the moving part 31 upward, the container lid will tend to move upward during the unlocking process, which will increase the friction between the clamp 2 and the lower edge of the container body 8, affecting the movement of the clamp 2. At the same time, when driving the moving part 31 upward, it is easy for the relative displacement between the container lid and the cooking container to occur when the clamp 2 is not fully unlocked, which may cause the cooking container to tip over and burn the user, posing a significant safety hazard. Therefore, in the solution provided in this application embodiment, the clamp 2 is unlocked by driving the moving part 31 downward, which is more stable and safer during use.

[0097] The container lid may also be equipped with a check valve and fasteners, which are connected to the housing 4, and the housing 4 is installed on the lid body 1. The housing 4, the mounting part 5, the drive part 3, and the clamp 2 can form a clamp assembly. During disassembly, the check valve and fasteners can be removed from the container lid, thereby separating the clamp assembly from the lid body 1, making it convenient for the user to separate the clamp 2 from the lid body 1 for cleaning or other purposes.

[0098] Based on the container lids provided in the above embodiments, this application also provides a cooking container, which includes a container body 8 and a container lid, the container lid being able to close onto the container body 8. The container lid can be any of the container lids involved in the above embodiments. The container lid has the above-mentioned technical effects, therefore the cooking container including this container lid also has corresponding technical effects, which will not be elaborated further.
