Description

Technical Field

[0001] This application relates to the field of kitchen utensil technology, and in particular to a pressure relief valve and a cooking container. Background Technology

[0002] When using a pressure cooker, users need to remove the valve body of the plug-in pressure relief valve to release the pressure inside the pot. Since high-temperature steam will be released when releasing the pressure, removing the valve body can easily cause burns to users, posing a safety hazard. Utility Model Content

[0003] This application provides a pressure relief valve and a cooking container to improve the safety of the pressure relief valve.

[0004] This application provides a pressure relief valve, the pressure relief valve comprising:

[0005] The base has an exhaust structure;

[0006] A valve body, which is mounted on the base;

[0007] A drive assembly, mounted on the base, is used to drive the valve body to open or close the exhaust structure;

[0008] The drive assembly includes a first drive member and a second drive member. The base includes a first mounting portion and a second mounting portion. The first drive member is mounted on the first mounting portion and is rotatable relative to the first mounting portion. The second drive member includes a first main body portion, a second main body portion, and a rotating portion. The rotating portion connects the first main body portion and the second main body portion. The first main body portion is used to connect with the first drive member, the second main body portion is used to connect with the valve body, and the rotating portion is connected to the second mounting portion. The second drive member is rotatable relative to the base.

[0009] When the first driving member rotates in the first direction, the first driving member can move in the direction close to the base. The first driving member drives the second driving member to rotate in the third direction, which is used to drive the valve body to move to the first position to open the exhaust structure.

[0010] When the first drive member rotates in the second direction, the first drive member can move in a direction away from the base. The valve body drives the second drive member to rotate in the fourth direction, and the valve body can move to the second position to close the exhaust structure.

[0011] In this design, the first and second driving components are linked, with the second driving component approximating a lever structure. Rotation of the first driving component generates displacement along the height of the pressure-limiting valve, which in turn drives the second driving component to rotate via the first main body. This leverage principle then drives the valve body at the other end of the second driving component to move, opening the pressure-limiting valve and releasing gas. This allows the user to release gas without needing to unplug or replug the pressure-limiting valve. This design utilizes both the first and second driving components to drive the valve body, preventing direct contact with the user and reducing the risk of burns during use, thus improving safety.

[0012] In one possible implementation, the first drive member and the first mounting part are threadedly connected.

[0013] In this design, the threaded connection improves the stability of the relative movement between the first driving component and the first mounting part, while converting rotation into axial movement, facilitating the first driving component's drive of the second driving component. The threaded connection is convenient to install, allowing users to install and remove the first driving component themselves. When replacing the first driving component, it can be removed and installed by rotation, making the operation relatively simple. Furthermore, the thread has a self-locking effect; after the user rotates it a certain angle, the first driving component remains in the corresponding position. Therefore, during venting, the user does not need to continuously drive the first driving component, reducing the possibility of burns and improving the safety of the cooking container. During the venting process, the displacement of the valve body can be controlled by adjusting the rotation angle of the first driving component, thereby controlling the opening of the pressure relief valve and the venting rate, reducing the possibility of splashing from the pressure relief valve and further enhancing the safety of the cooking container.

[0014] In one possible implementation, the valve body is movable between a first position and a second position, and the first drive member is rotatable between a third position and a fourth position. When the valve body is in the first position, the first drive member is in the third position, and when the valve body is in the second position, the first drive member is in the fourth position. When the first drive member switches between the third position and the fourth position, the rotation angle of the first drive member is α, and 30°≤α≤90°.

[0015] In this design, the rotation angle α is appropriate. Furthermore, the threaded connection length between the first driving component and the first mounting part is appropriate, which can reduce material costs and improve the user experience while ensuring the driving force of the first driving component.

[0016] In one possible implementation, the length of the first main body portion is less than the length of the second main body portion, and / or the cross-sectional area of ​​the first main body portion is less than the cross-sectional area of ​​the second main body portion.

[0017] Furthermore, in this solution, the weight of the first main body is less than that of the second main body, ensuring that when the exhaust valve is in the closed state, i.e., when the valve body is in the second position and the first drive member is in the fourth position, the second main body can fall away from the valve body by gravity, ensuring that when the exhaust valve is required to be in the closed state, the second drive member will not accidentally touch the valve body and affect the use of the cooking container.

[0018] In one possible implementation, the length of the first main body is A, the length of the second main body is B, and the following condition is met: 2A≤B≤5A.

[0019] Furthermore, in this design, the weight difference between the first main body and the second main body is moderate. This allows the second main body to fall away from the valve body under gravity, while reducing the difficulty of operation for the user and better meeting actual usage needs.

[0020] In one possible implementation, the second main body portion includes a first body portion and a second body portion, the first body portion connecting the second body portion and the rotating portion, and at least a portion of the second body portion bending toward the valve body.

[0021] In this design, a second body portion that bends toward the valve body is provided in the second main body portion, which facilitates contact between the second driving component and the valve body, reduces the possibility of interference between the edge of the valve body and the second driving component, and helps to improve the stability of the second driving component in driving the valve body.

[0022] In one possible implementation, the rotating part is an arc-shaped structure, which is sleeved on the second mounting part, and the arc-shaped structure has an opening.

[0023] In this solution, the installation method of the second drive component being connected to the second mounting part through the opening is more convenient, and when the second drive component is damaged, the parts can be easily replaced, ensuring the functionality of the cooking container in a timely manner, reducing maintenance difficulty, improving the user experience, and increasing the service life of the cooking container.

[0024] In one possible implementation, the pressure relief valve includes an elastic element sleeved on the outside of the exhaust structure, and the valve body sleeved on the outside of the elastic element, wherein the elastic element is used to prevent the valve body from detaching from the exhaust structure.

[0025] In this solution, the elastic element can be a retaining ring. Compared with the plug-in type pressure relief valve, the pressure relief valve can be vented without disassembling the valve body, which can reduce the impact of disassembly and assembly on the retaining ring and help extend the service life of the retaining ring.

[0026] In one possible implementation, the base has a cavity, at least a portion of the valve body is located in the cavity, the bottom wall of the cavity is provided with an exhaust hole, the exhaust structure is disposed in the exhaust hole, and the cross-sectional area of ​​the cavity gradually increases in the direction away from the bottom wall.

[0027] This design creates an inclined sidewall in the cavity, which helps guide the exhaust gas upward, reducing the possibility of gas accumulation in the base cavity. At the same time, in this solution, the gas can be drawn upward through the cavity of the base, which is safer than the solution of exhausting gas in all directions, and can reduce the possibility of steam scalding users.

[0028] This application embodiment also provides a cooking container, the cooking container comprising:

[0029] Container body;

[0030] A container lid that fits over the container body;

[0031] The container lid is provided with a pressure limiting valve, which is any of the pressure limiting valves described above.

[0032] 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

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] In one specific embodiment, this application provides a cooking container, which includes a container lid and a container body 4. The container lid can be closed onto the container body 4 to ensure the sealing of the container body 4. The container lid is provided with a pressure limiting valve, which is used to regulate the pressure inside the cooking container. By controlling the amount of steam discharged, the pressure inside the pot is maintained at a preset value, which raises the boiling point of the liquid in the cooking container, thereby significantly shortening the cooking time. When the pressure inside the cooking container rises abnormally, the pressure limiting valve will automatically release pressure to prevent the cooking container from rupturing due to overpressure and ensure the safety of the user during use.

[0064] refer to Figure 1 and Figure 2 As shown, the pressure relief valve includes a base 1 with an exhaust structure 11, a valve body 2 mounted on the base 1, and a drive assembly 3. The drive assembly 3 is used to drive the valve body 2 to open or close the exhaust structure 11.

[0065] refer to Figure 3 As shown, the base 1 has a first mounting portion 12 and a second mounting portion 13. The drive assembly 3 includes a first drive member 31 and a second drive member 32. The first drive member 31 is mounted on the first mounting portion 12 and is rotatable relative to the first mounting portion 12. The second drive member 32 includes a first main body portion 321, a second main body portion 322, and a rotating portion 323. The rotating portion 323 connects the first main body portion 321 and the second main body portion 322. The first main body portion 321 is used to connect with the first drive member 31, and the connection method can be a relatively fixed connection such as a hinge, or a connection method such as an abutment. The second main body portion 322 is used to connect with the valve body 2, and the connection method can be a relatively fixed connection such as a hinge, or a connection method such as an abutment. The rotating portion 323 is connected to the second mounting portion 13, and the second drive member 32 is rotatable relative to the base 1.

[0066] refer to Figure 4As shown, when the first driving member 31 rotates along the first direction a, the first driving member 31 can move along the direction close to the base 1. The first driving member 31 drives the second driving member 32 to rotate along the third direction c, which is used to drive the valve body 2 to move to the first position to open the exhaust structure 11. At this time, the pressure relief valve can perform exhaust work.

[0067] refer to Figure 5 As shown, when the first driving member 31 rotates along the second direction b, the first driving member 31 can move in a direction away from the base 1. The valve body 2 drives the second driving member 32 to rotate along the fourth direction d. The valve body 2 can move to the second position to close the exhaust structure 11. At this time, the exhaust operation of the pressure relief valve is closed.

[0068] By linking the first driving component 31 with the second driving component 32, the second driving component 32 can be approximated as a lever structure. After the first driving component 31 rotates, it generates displacement along the height direction of the pressure-limiting valve, which drives the second driving component 32 to rotate via the first main body 321. Utilizing the lever principle, this drives the valve body 2 at the other end of the second driving component 32 to move, thereby opening the pressure-limiting valve and venting air. This allows the user to achieve the purpose of venting the pressure-limiting valve without needing to unplug or replug it. This design utilizes the first driving component 31 and the second driving component 32 to drive the valve body 2, preventing the user from directly contacting the valve body 2, thus reducing the possibility of burns during use and improving safety.

[0069] In one specific embodiment, reference is made to... Figure 4 or Figure 5 As shown, the first driving component 31 and the first mounting part 12 are connected by threads.

[0070] Threaded connections offer advantages such as high load-bearing capacity and reliability. A well-designed threaded connection can distribute stress and prevent localized overload. In this embodiment, it improves the stability of the relative movement between the first driving component 31 and the first mounting part 12, while also converting rotation into axial movement, facilitating the first driving component 31's drive of the second driving component 32. Threaded connections are convenient to install; users can install and remove the first driving component 31 themselves. When replacing the first driving component 31, it can be disassembled and installed by rotation, making the operation relatively simple. Furthermore, the threaded connection has a self-locking effect; after the user rotates it a certain angle, the first driving component 31 remains in the corresponding position. Therefore, during the venting process, the user does not need to continuously drive the first driving component 31, reducing the possibility of burns and improving safety. During opening, the displacement of the valve body 2 can be controlled by controlling the rotation angle of the first driving component 31, thereby controlling the opening degree of the pressure relief valve and the venting rate, reducing the possibility of splashing from the pressure relief valve and further improving safety.

[0071] In one specific embodiment, reference is made to... Figure 4 and Figure 5 As shown, valve body 2 can move between a first position and a second position; Reference Figure 6 and Figure 7 As shown, the first drive member is capable of rotating between the third and fourth positions. (Reference) Figure 5 As shown, when valve body 2 is in the first position, the first drive member 31 is in the third position, and the exhaust valve is in the open state; Reference Figure 5 As shown, when valve body 2 is in the second position, the first drive member 31 is in the fourth position, and the exhaust valve is in the closed state. (Reference) Figure 6 and Figure 7 As shown, when the first driving member 31 switches between the third position and the fourth position, the rotation angle of the first driving member 31 is α, and 30°≤α≤90°. For example, the rotation angle α can be 30°, 35°, 40°, 45°, 50°, 52°, 60°, 80°, 90°, etc.

[0072] When the rotation angle α is too small, the threaded connection length between the first driving component 31 and the first mounting part 12 is too short, resulting in unstable engagement between them. Furthermore, the driving force transmitted from the first driving component 31 to the second driving component 32 is insufficient, and accidental activation is likely, leading to the pressure relief valve opening or closing incorrectly. When the rotation angle α is too large, the threaded connection length between the first driving component 31 and the first mounting part 12 is too long, increasing material manufacturing costs. Moreover, the excessive stroke of the first driving component 31 during opening and closing of the pressure relief valve can lead to delays in opening and closing, negatively impacting the user experience. In this embodiment, the rotation angle α is moderate, and furthermore, the threaded connection length between the first driving component 31 and the first mounting part 12 is moderate, ensuring the driving force of the first driving component 31 while reducing material costs and improving the user experience.

[0073] In one specific embodiment, the length of the first main body portion 321 is less than the length of the second main body portion 322, and / or the cross-sectional area of ​​the first main body portion 321 is less than the cross-sectional area of ​​the second main body portion 322.

[0074] With this design, the weight of the first main body 321 is less than that of the second main body 322, ensuring that when the exhaust valve is closed, i.e., when the valve body 2 is in the second position and the first drive member 31 is in the fourth position, the second main body 322 can fall away from the valve body 2 by gravity. This ensures that when the exhaust valve is required to be closed, the second drive member 32 will not accidentally touch the valve body 2 and affect the use of the cooking container.

[0075] In one specific embodiment, reference is made to... Figure 4 or Figure 5 As shown, the length of the first main body 321 is set to A, and the length of the second main body 322 is set to B, and the following conditions are met: 2A≤B≤5A. For example, the length B of the second main body 322 can be 2A, 2.5A, 3A, 3.5A, 4A, 4.5A, 5A, etc.

[0076] In this embodiment, when the length B of the second main body 322 is less than 2A, the weight difference between the first main body 321 and the second main body 322 is not significant. This cannot guarantee that the second main body 322 will fall away from the valve body 2 under gravity, potentially causing the second drive member 32 to accidentally contact the valve body 2, affecting the use of the cooking container. Furthermore, if the second main body 322 is too short, the contact area with the valve body 2 is small, leading to unstable contact. During movement, the valve body 2 may easily detach from the second main body 322, affecting the normal use of the pressure relief valve. When the length B of the second main body 322 is greater than 5A, the weight of the second main body 322 is too large relative to the first main body 321, requiring a greater driving force to drive the second main body 322 towards the valve body 2. This may also exacerbate fatigue damage to the second drive member 32. Moreover, an excessively large size of the second main body 322 will increase the overall size of the pressure relief valve. In this embodiment, the weight difference between the first main body 321 and the second main body 322 is moderate. While enabling the second main body 322 to fall away from the valve body 2 by gravity, it reduces the difficulty of operation for the user and is more in line with actual usage needs.

[0077] In one specific embodiment, reference is made to... Figure 4 or Figure 5 As shown, the second main body 322 includes a first body part 322a and a second body part 322b. The first body part 322a connects the second body part 322b and the rotating part 323. At least a portion of the second body part 322b is bent toward the valve body 2.

[0078] By providing a second body portion 322b that bends toward the valve body 2 through the second main body portion 322, it is easier for the second driving member 32 to contact the valve body 2, reducing the possibility of interference between the edge of the valve body 2 and the second driving member 32, and improving the stability of the second driving member 32 in driving the valve body 2.

[0079] In one specific embodiment, the rotating part 323 has an arc-shaped structure and is sleeved on the second mounting part 13. The arc-shaped structure has an opening.

[0080] Compared to the inlay fixing method, the installation method of the second driving component 32 being sleeved onto the second mounting part 13 through the opening is more convenient. During installation and disassembly, the second mounting part 13 can simply enter or disengage from the rotating part 323 along the opening. When the second driving component 32 is damaged, the part can be easily replaced, ensuring the functionality of the cooking container in a timely manner, reducing maintenance difficulty, improving the user experience, and increasing the service life of the cooking container.

[0081] In one specific embodiment, reference is made to... Figure 3 As shown, the pressure relief valve includes an elastic element 21, which is sleeved on the outside of the exhaust structure 11. The valve body 2 is sleeved on the outside of the elastic element 21. The elastic element 21 is used to restrict the valve body 2 from detaching from the exhaust structure 11.

[0082] By setting the elastic element 21, the relative position between the pressure relief valve and the venting structure 11 can be limited, preventing the valve body 2 from detaching from the venting structure 11 when the container lid is inverted or the internal pressure of the cooking container is too high. This not only prevents the valve body 2 from being lost, but also avoids the valve body 2 from injuring the user if it detaches from the container lid. In this embodiment, the elastic element 21 can be a retaining spring, etc. Compared with a plug-in type pressure relief valve, the solution provided in this application embodiment can realize the venting function of the pressure relief valve without disassembling the valve body 2, thereby reducing the impact of the disassembly and assembly process on the retaining spring and helping to extend the service life of the retaining spring.

[0083] In one specific embodiment, reference is made to... Figure 3 As shown, the base 1 has a cavity 14, at least a portion of the valve body 2 is located in the cavity 14, the bottom wall of the cavity 14 is provided with an exhaust hole, the exhaust structure 11 is provided in the exhaust hole, and the cross-sectional area of ​​the cavity 14 gradually increases in the direction away from the bottom wall.

[0084] This design allows for the formation of inclined sidewalls in the cavity 14, which helps guide the exhaust gas upwards, thereby reducing the possibility of gas accumulation in the cavity 14 of the base 1. Furthermore, the solution provided in this application embodiment allows the gas to be drawn upwards through the cavity 14 of the base 1, which is safer than the solution of exhausting gas to the surroundings, reducing the possibility of steam scalding the user.

[0085] In one specific embodiment, the first driving member 31 can be a knob. The first driving member 31 is sleeved on the first mounting portion 12. To facilitate user operation, a protrusion 311 can be provided on the first driving member 31, which the user can drive through. (See reference) Figure 6 and Figure 7 As shown, during the process of the first driving member 31 rotating from the third position to the fourth position, the rotation angle during the movement is the rotation angle α.

[0086] In addition to the cylindrical structure in this embodiment, the first driving component 31 can also be configured as other shapes, such as rectangles, triangles, etc. The second driving component 32 can be a one-piece molded structure. The one-piece molding process improves the fatigue strength of the part, reduces the risk of damage, and helps to extend the service life of the part. The rotating part 323 of the second driving component 32 is connected to the second mounting part 13 and is fixed in a ring around the rotating shaft of the second mounting base. It also connects the first main body part 321 and the second main body part 322. Its main function is to connect the first main body part 321 and the second main body part 322 to ensure that the force on the second driving component 32 is uniform and to fix the position of the second driving component 32, ensuring the feasibility of the rotation movement of the second driving component 32. The first main body part 321 of the second driving component 32 is used to connect with the first driving component 31 and transmit the driving force of the first driving component 31 to the second main body part 322. The second main body part 322 of the second driving component 32 is used to connect with the valve body 2. When the second main body part 322 receives the driving force transmitted from the first main body part 321, the second driving component 32 can be fixed along the rotating shaft of the second mounting part 13 and rotate relative to the base 1.

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.
