Description

Technical Field

[0001] This application relates to the field of kitchen utensils technology, and in particular to a micro-pressure pot lid and a micro-pressure pot. Background Technology

[0002] A pressure cooker creates a slightly higher pressure environment inside the pot by locking the lid to the pot body. This accelerates water boiling and raises the temperature, shortening cooking time while preserving the food's nutrients. However, existing pressure cookers have complex lid-to-pot locking mechanisms that are not very versatile. Utility Model Content

[0003] This application provides a pressure cooker lid and a pressure cooker, which are easy to operate and have high versatility.

[0004] The first aspect of this application provides a micro-pressure cooker lid, which includes:

[0005] Cover;

[0006] The mounting base is disposed above the cover;

[0007] Two fasteners are arranged radially opposite to each other along the cover body. The fasteners are slidably connected to the mounting base and can slide radially along the cover body to achieve snap-fit or disengagement.

[0008] A control element is disposed between the two fasteners, the control element passes through the mounting base, and is capable of sliding in the vertical direction;

[0009] When the control element is moved upward, it interacts with the fastener, forcing the fastener to move outward and disengage from the latch.

[0010] The pressure cooker lid provided in this application includes a lid body, a mounting base, two fasteners, and a control component. The mounting base is located above the lid body. The fasteners are slidably connected to the mounting base and can slide radially along the lid body to achieve locking or unlocking. The control component is located between the two fasteners, passes through the mounting base, and can slide vertically. When the control component is operated to move upward, it interacts with the fasteners, forcing the fasteners to move outward and unlock. Therefore, the direction of force applied by the user to operate the control component is consistent with the direction of force applied by the user to lift the pressure cooker lid, thus enabling unlocking and opening in one step, simplifying the opening operation of the pressure cooker lid. Furthermore, the fasteners can directly lock onto the flange of the pot body, offering high versatility.

[0011] Optionally, the fastener has a first surface located at the end of the fastener facing the control member, and the control member has second surfaces on opposite sides, with the second surfaces abutting against the first surface; at least one of the first and second surfaces is a wedge-shaped surface; along a top-to-bottom direction, the wedge-shaped surface gradually tilts away from the control member, so as to convert the upward movement of the control member into the outward movement of the fastener. Through the spreading effect of the wedge-shaped surface, the two fasteners are moved away from each other, resulting in a simple structure, strong load-bearing capacity, and stable and efficient operation.

[0012] Optionally, the fastener has a first groove on its end face facing the control member, and protrusions are respectively provided on both sides of the control member, with the protrusions inserted into the first groove; the first surface is disposed on the upper wall of the first groove, and the second surface is disposed on the upper surface of the protrusion. The protrusion slides relative to the first groove, providing precise guidance and limiting, and preventing the fastener and control member from deflecting relative to each other, thus affecting the normal contact and fit between the first surface and the second surface.

[0013] Optionally, the first groove extends through the lower surface of the fastener. The control element can be inserted from bottom to top. During the upward insertion of the control element, the protrusion can naturally enter the first groove from below the fastener, eliminating the need to pry the two fasteners outward to create a large installation space, thereby simplifying the assembly operation of the micro-pressure cooker lid.

[0014] Optionally, the fastener has an end plate at one end facing the control member, and the first groove is recessed in the end plate on the side facing the control member. Second grooves are provided on both sides of the first groove, and the second grooves are recessed in the end plate on the side away from the control member. An elastic element is installed in each of the second grooves, and both ends of the elastic element elastically abut against the end plate and the mounting base, forcing the fastener to move inward to achieve a locking mechanism. On one hand, the first and second grooves are staggered, and their openings face opposite directions, which improves space utilization and makes the overall structure more compact. On the other hand, the two elastic elements are located on both sides of the control member, and both the elastic elements and the control member act on the end plate, making the overall force on the end plate more even.

[0015] Optionally, a handle is provided above the mounting base, and the control component is inserted into the handle and can slide vertically within the handle. A portion of the control component protrudes from the side wall of the handle. The user can operate the control component upwards while holding the handle, allowing the handle to bear the weight of the pressure cooker lid. The control component only drives the fastener, thus preventing excessive force on the control component and causing deformation or breakage. Furthermore, after opening the lid, the control component can be released promptly to return to its original position, shortening the actual operating time of the control component and extending the service life of the pressure cooker lid.

[0016] Optionally, the handle includes a first connecting portion and a gripping portion. The first connecting portion is connected to the mounting base, and the two opposite sides of the first connecting portion are a first side and a second side, respectively. The gripping portion is disposed on the first side, the control component is inserted into the first connecting portion, and a portion of the control component protrudes from the second side. The user can grip the gripping portion with four fingers and leave the thumb free to operate the control component upward, ensuring that the user can stably and reliably lift the pressure cooker lid while accurately and forcefully operating the control component.

[0017] Optionally, the control component has a detachably connected operating block on one side, and the handle has a through groove on its side wall. The control component is inserted into the handle from bottom to top, and the operating block passes through the through groove from the outside to the inside and is connected to the control component. Thus, when installing and removing the control component, the handle and the mounting base can remain connected, eliminating the need for repeated disassembly and reassembly operations and reducing the risk of the handle becoming loose or falling off.

[0018] Optionally, the handle and the mounting base are integrally formed. This effectively ensures the stability and reliability of the handle, preventing it from becoming loose or falling off during use, and also improves the overall integrity and appearance of the pressure cooker lid.

[0019] A second aspect of this application provides a micro-pressure cooker, comprising a pot body and any of the micro-pressure cooker lids provided in this application. The pot body has an outwardly folding flange at its opening, and the cooker lid closes to the opening of the pot body. A fastener is engaged with the flange. The direction of force applied by the user operating the control component is consistent with the direction of force applied by the user lifting the micro-pressure cooker lid, thereby enabling unlocking and opening the lid in one step, simplifying the opening operation of the micro-pressure cooker lid. Furthermore, the fastener can be directly engaged with the flange of the pot body, offering high versatility.

[0051] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also 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.

[0055] like Figures 1-5 As shown, this application provides a micro-pressure cooker lid that can cover the opening of a pot body 7 and together with the pot body 7 constitute a micro-pressure cooker. The micro-pressure cooker lid includes a lid body 1, a mounting base 2, and two fasteners 3. The lid body 1 cooperates with the opening of the pot body 7. A sealing ring 11 can be provided on the edge of the lid body 1, and a micro-pressure valve 12 can be provided on the lid body 1 to create a sealed environment inside the pot and generate the expected micro-pressure. The mounting base 2 is located above the lid body 1 and can be fixed to the lid body 1 by screws or other means. The two fasteners 3 are arranged radially opposite to each other along the lid body 1. When the micro-pressure cooker lid is closed on the opening of the pot body 7, the fasteners 3 can be snapped into the flange 71 and other fitting structures of the pot body 7 from the outside to the inside, thereby locking the lid on the pot body 7 and meeting the micro-pressure cooking requirements. In the various embodiments of this application, only the flange 71 of the pot body 7 is used as an example for detailed description.

[0056] Furthermore, the fastener 3 is slidably connected to the mounting base 2 and can slide radially along the lid 1 to achieve locking or unlocking. Specifically, when the fastener 3 moves inward (i.e., the two fasteners 3 approach each other), the fastener 3 can lock, that is, the fastener 3 can lock onto the flange 71 of the pot body 7, thereby locking the lid onto the pot body 7 to meet the needs of micro-pressure cooking. When the fastener 3 moves outward (i.e., the two fasteners 3 move away from each other), the fastener 3 can unlock, that is, the fastener 3 can disengage from the flange 71 of the pot body 7, thereby unlocking the micro-pressure lid from the pot body 7, making it convenient for the user to open or close the lid.

[0057] Furthermore, the control element 4 is positioned between the two fasteners 3, passing through the mounting base 2 and capable of sliding vertically. Operating the control element 4 upwards causes it to interact with the fasteners 3, forcing them to move outwards and disengage. Thus, the direction of force applied by the user to the control element 4 is consistent with the direction of force applied by the user to lift the pressure cooker lid, enabling simultaneous unlocking and opening, simplifying the opening operation of the pressure cooker lid. Additionally, the fasteners 3 can directly engage with the flange 71 of the pot body 7, offering high versatility.

[0058] Specifically, the control element 4 and the fastener 3 can be fitted in any way that can change the direction of linear motion, such as with mutually cooperating guide pins and guide grooves, as long as the upward movement of the control element 4 can be converted into the outward radial movement of the fastener 3 along the lid 1. An elastic element 5 can be provided between the two fasteners 3 or between the fastener 3 and the mounting base 2. The elastic element 5 forces the fastener 3 to move inward to achieve the locking mechanism. In other words, after the user releases the control element 4, the fastener 3 will automatically lock under the action of the elastic element 5, eliminating the need for manual operation of the fastener 3 and making the use of the pressure cooker more convenient.

[0059] A pad 6 can be provided between the cover 1 and the mounting base 2. A fastener 3 is clamped between the pad 6 and the mounting base 2 to prevent the fastener 3 from directly contacting the surface of the cover 1, thus preventing scratches or other damage. The fastener 3 may include a snap-fit part 3a and a push plate 3b connected to each other. The snap-fit part 3a and the push plate 3b can be connected to each other in a non-removable manner, such as by integral molding, or in a detachable manner, such as by screws. The snap-fit part 3a is located at the edge of the cover 1 to achieve snap-fit; the push plate 3b slides with the mounting base 2 to achieve guiding and limiting functions.

[0060] Furthermore, a handle 21 is provided above the mounting base 2. The control component 4 is inserted into the handle 21 and can slide vertically within the handle 21. A portion of the control component 4 protrudes from the side wall of the handle 21. While holding the handle 21, the user can operate the control component 4 to move upwards, allowing the handle 21 to bear the weight of the pressure cooker lid. The control component 4 only drives the fastener 3, thus preventing the control component 4 from being deformed or broken due to excessive force. After the lid opening operation is completed, the control component 4 can be released and returned to its original position in a timely manner, shortening the actual working time of the control component 4 and extending the service life of the pressure cooker lid.

[0061] Specifically, an operating block 43 protrudes from one side of the control component 4, and a through groove 214 is provided on the side wall of the handle 21. The operating block 43 passes through the through groove 214 and protrudes from the side wall of the handle 21. The user applies external force to the operating block 43 to make the control component 4 slide upward.

[0062] Furthermore, the operating block 43 is detachably connected to the control component 4. For example, the operating block 43 can be connected to the control component 4 by screws or clips. The control component 4 is inserted into the handle 21 from bottom to top, and the operating block 43 passes through the through slot 214 from the outside to the inside and is connected to the control component 4. Thus, when installing and removing the control component 4, the handle 21 and the mounting base 2 can remain connected, thereby eliminating the need for repeated disassembly and reassembly of the handle 21 and reducing the risk of the handle 21 becoming loose or falling off.

[0063] Furthermore, when the operating block 43 is detachably connected to the control component 4, the handle 21 and the mounting base 2 are integrally formed. This not only effectively ensures the stability and reliability of the handle 21 and prevents abnormalities such as loosening or falling off during use, but also improves the overall integrity of the pressure cooker lid and enhances its appearance.

[0064] Furthermore, the handle 21 includes a first connecting portion 211 and a gripping portion 212. The first connecting portion 211 is connected to the mounting base 2, thereby fixing the handle 21 to the mounting base 2. The two opposite sides of the first connecting portion 211 are a first side and a second side, respectively. The gripping portion 212 is disposed on the first side, and the control member 4 is inserted into the first connecting portion 211, with a portion of the control member 4 protruding from the second side. The user can grip the gripping portion 212 with four fingers and leave the thumb to operate the control member 4 to move upward, which can ensure that the user can lift the pressure cooker lid stably and reliably, and can also operate the control member 4 precisely and forcefully.

[0065] Furthermore, the handle 21 also includes a second connecting portion 213, which is located at the end of the grip portion 212 away from the first connecting portion 211, and is connected to the mounting base 2. The handle 21 is fixed to the mounting base 2 via the first connecting portion 211 and the second connecting portion 213 respectively, to increase the stability and reliability of the handle 21.

[0066] Furthermore, the fastener 3 is provided with a first surface 31, located at the end of the fastener 3 facing the control member 4. The control member 4 has second surfaces 41 on opposite sides, which abut against the first surface 31. At least one of the first surface 31 and the second surface 41 is a wedge-shaped surface. Along a downward direction, the wedge-shaped surface gradually tilts away from the control member 4, converting the upward movement of the control member 4 into the outward movement of the fastener 3. Through the spreading effect of the wedge-shaped surface, the two fasteners 3 are moved away from each other, resulting in a simple structure, strong load-bearing capacity, and stable and efficient operation.

[0067] Furthermore, both the first surface 31 and the second surface 41 are wedge-shaped surfaces, forming a accommodating space between the two first surfaces 31 that is smaller at the top and larger at the bottom, and forming a block between the two second surfaces 41 that is smaller at the top and larger at the bottom. The first surface 31 and the second surface 41 form surface contact, further increasing the load-bearing capacity and improving the stability of the operation.

[0068] Furthermore, the fastener 3 has a first groove 32 on its end face facing the control member 4, and protrusions 42 are respectively provided on both sides of the control member 4, with the protrusions 42 inserted into the first groove 32. A first surface 31 is provided on the upper wall of the first groove 32, and a second surface 41 is provided on the upper surface of the protrusions 42. The protrusions 42 slide relative to each other along the first groove 32, playing a precise guiding and limiting role, which can prevent the fastener 3 and the control member 4 from deflecting relative to each other, affecting the normal contact and cooperation between the first surface 31 and the second surface 41.

[0069] Furthermore, the end of the fastener 3 facing the control component 4 can be provided with an end plate 33. The first groove 32 is recessed in the side of the end plate 33 facing the control component 4, thereby increasing the local height of the fastener 3 to meet the movement stroke requirements of the control component 4. Second grooves 34 are provided on both sides of the first groove 32, recessed in the side of the end plate 33 away from the control component 4. Elastic members 5 are installed in the second grooves 34, with their two ends elastically abutting against the end plate 33 and the mounting base 2, respectively, to force the fastener 3 to move inward and achieve a locking mechanism. On one hand, the end plate 33 has an overall concave-convex structure, causing the first groove 32 and the second groove 34 to be staggered, and the groove openings of the first groove 32 and the second groove 34 to face opposite directions, thereby improving space utilization and making the overall structure more compact. On the other hand, the two elastic members 5 are located on both sides of the control component 4, and both the elastic members 5 and the control component 4 act on the end plate 33, making the overall force on the end plate 33 more even.

[0070] Furthermore, the first groove 32 penetrates the lower surface of the fastener 3, forming an open structure with the first groove 32 connected to the bottom of the fastener 3. The control component 4 can be inserted from bottom to top. During the upward insertion of the control component 4, the protrusion 42 can naturally enter the first groove 32 from below the fastener 3, without having to pry the two fasteners 3 outward to create a large installation space, thus simplifying the assembly operation of the micro-pressure pot lid.

[0071] In addition, this application embodiment also provides a cookware, which includes a pot body 7 and any kind of pot lid provided in this application. The pot body 7 has an outwardly folding flange 71 at the mouth. The pot lid covers the mouth of the pot body 7. When the latching part 3a latches, the latching part 3a latches onto the flange 71.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
