Description

Technical Field

[0001] This application relates to the field of kitchen utensils technology, and in particular to a pot lid and a micro-pressure cooker. 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 increases temperature, shortening cooking time while preserving nutrients in the food. However, existing pressure cookers have complex lid-to-pot locking mechanisms that are not very versatile. Utility Model Content

[0003] This application provides a pot lid and a micro-pressure cooker, which provides a micro-pressure pot lid that is easy to operate and has high versatility.

[0004] The first aspect of this application provides a pot lid, which includes:

[0005] Cover;

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

[0007] At least one snap-fit ​​assembly, the snap-fit ​​assembly including a connector and a fastener, the connector being hinged to the mounting base and capable of rotating in a direction toward or away from the axis of the cover, the fastener being hinged to the end of the connector away from the mounting base, and the end of the fastener away from the axis of the cover having a snap-fit ​​portion;

[0008] When the connector rotates towards the axis of the cover, and the fastener and the connector move closer to each other, the latching part can achieve latching.

[0009] The pot lid provided in this application includes a lid body, a mounting base, and at least one snap-fit ​​assembly. The mounting base is disposed above the lid body. The snap-fit ​​assembly includes a connector and a fastener that are hinged to each other. The connector is hinged to the mounting base and can rotate towards or away from the axis of the lid body. The fastener is hinged to the end of the connector away from the mounting base. The hinge axes at both ends of the connector are parallel to each other. The end of the fastener away from the axis of the lid body is provided with a snap-fit ​​portion. When the connector rotates towards the axis of the lid body and the fastener and connector move closer to each other, the snap-fit ​​portion can snap together, thereby locking the pot lid onto the pot body to meet the requirements of micro-pressure cooking. When the connector rotates away from the axis of the lid body, or when the fastener and connector move away from each other, the snap-fit ​​portion can disengage, thereby unlocking the pot lid from the pot body, making it convenient for the user to open or close the lid. Therefore, the lid and the pot body are locked together by the snap-fit ​​assembly. The user can directly operate the snap-fit ​​assembly to lock and unlock the lid and the pot body. The operation is simple. In addition, the snap-fit ​​part can be directly snapped onto the flange of the pot body, making it highly versatile.

[0010] Optionally, the fastener includes a main body hinged to the end of the connector away from the mounting base, and a latching portion disposed at the end of the main body away from the axis of the lid. When the latching portion engages, the main body abuts against the upper surface of the mounting base. The connector and the main body abut against each other on the upper surface of the mounting base, thereby allowing the main body to directly provide a downward force to the mounting base, and the latching portion to directly provide an upward force to the flange of the pot body, increasing the stability and reliability of the connection between the lid and the pot body.

[0011] Optionally, the middle part of the main body is hinged to the end of the connector away from the mounting base, and the section of the main body near the axis of the cover is the operating section. Because a large distance is formed between the operating section and the rotation center of the connector, and between the operating section and the fulcrum of the fastener, a force-saving lever is formed, making the operation of the buckle assembly more effortless.

[0012] Optionally, the main body includes a top wall and two opposing first side walls. The first side walls are located on the side of the top wall facing the mounting base. The connector is disposed between the two first side walls, with its two sides respectively hinged to the two first side walls. When the latching part is engaged, the first side walls abut against the upper surface of the mounting base, and the connector is housed between the main body and the mounting base. This design allows both the main body and the connector to form a continuous plate-like structure, ensuring the structural strength of both. Furthermore, it allows the connector to be concealed, reducing exposed parts and simplifying the external shape of the lid.

[0013] Optionally, the latching part is disposed on the side of the top wall facing the mounting base. The latching part connects the top wall and the two first side walls, and extends beyond the height range of the first side walls. This ensures both the connection strength between the latching part and the main body and allows the latching part to form a cantilever structure below the main body, thereby maintaining a certain degree of elasticity and ensuring that the latching assembly can move normally.

[0014] Optionally, the edge of the lid is provided with a sealing ring, and the downward-facing side of the sealing ring is provided with a sealing surface. The axial deformation of the sealing ring provides a flexible floating space between the lid and the pot body, which not only keeps the latching part in contact with the flange of the pot body, increasing the stability of the latching, but also increases the axial adaptation range of the latching part, allowing it to latch with flanges of different thicknesses.

[0015] Optionally, the sealing ring includes a first annular portion that fits against the upper surface of the lid, and the mounting base elastically abuts against the side of the first annular portion opposite to the lid. The axial deformation of the first annular portion provides a flexible floating space for the lid itself, which not only keeps the latching part in contact with the flange of the pot body, increasing the stability of the latching, but also increases the axial adaptation range of the latching part, allowing it to latch with flanges of different thicknesses.

[0016] Optionally, the mounting base has a receiving groove recessed into its upper surface, extending through one end of the mounting base away from the axis of the lid. The connecting member is disposed within the receiving groove. When the latching part is engaged, the connecting member is close to the bottom of the receiving groove, a portion of the fastener is housed within the receiving groove, and the latching part protrudes from the end of the receiving groove away from the axis of the lid. On one hand, the receiving groove surrounding the fastener provides protection, reducing or preventing accidental operation of the fastener during cooking, thereby lowering the risk of accidental unlocking of the lid from the pot body. On the other hand, the fastener being housed within the receiving groove reduces the overall volume of the lid and makes its appearance more regular and neat.

[0017] Optionally, the mounting base is located at the center of the lid and extends radially along the lid. There are two latching components, each located at one end of the mounting base. On one hand, the two latching components latch on opposite sides of the pot body, increasing the stability and reliability of the connection between the lid and the pot body. On the other hand, the user can operate one latching component with each hand, locking or unlocking the lid and pot body in a single operation.

[0018] A second aspect of this application provides a micro-pressure cooker, comprising a pot body and any type of lid provided in this application. The pot body has an outwardly folding flange at its opening, and the lid closes to the opening of the pot body. When the latching part is engaged, it engages with the flange. The lid and pot body are locked together via the latching assembly. The user can directly operate the latching assembly to lock and unlock the lid and pot body, making operation simple. Furthermore, the latching part can directly engage with the flange of the pot body, offering high versatility.

[0047] 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

[0048] 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.

[0049] 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.

[0050] 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.

[0051] like Figures 1-5 As shown, this application provides a pot lid that can cover the opening of a pot body 5 and together with the pot body 5 constitute a micro-pressure cooker. The pot lid includes a lid body 1, a mounting base 2, and at least one snap-fit ​​component 3. The lid body 1 cooperates with the opening of the pot body 5. The mounting base 2 is disposed above the lid body 1 and can be fixed to the lid body 1 by means of screws or other methods. The mounting base 2 can be connected to a handle 21 to facilitate the user to hold and lift the pot lid. The snap-fit ​​component 3 is connected to the mounting base 2. When the pot lid is closed on the opening of the pot body 5, the snap-fit ​​component 3 can snap onto the flange 51 or other structures of the pot body 5, thereby locking the pot lid onto the pot body 5 and meeting the requirements of micro-pressure cooking. In the various embodiments of this application, only the snap-fit ​​component 3 snapping onto the flange 51 of the pot body 5 is described in detail.

[0052] Furthermore, the latching assembly 3 includes a connector 31 and a fastener 32 that are hinged to each other. The connector 31 is hinged to the mounting base 2 and can rotate in a direction closer to or away from the axis of the cover 1; that is, the connector 31 rotates in a vertical plane. The fastener 32 is hinged to the end of the connector 31 away from the mounting base 2. The hinge axes at both ends of the connector 31 are parallel to each other, and the end of the fastener 32 away from the axis of the cover 1 is provided with a latching portion 321. When the connector 31 rotates in a direction closer to the axis of the cover 1, and the fastener 32 and the connector 31 move closer to each other, the latching portion 321 can achieve latching (see reference). Figure 2 Point A in the middle and Figure 3 In other words, the latching part 321 can latch onto the flange 51 of the pot body 5, thereby locking the lid onto the pot body 5 to meet the requirements of micro-pressure cooking; when the connecting piece 31 rotates away from the axis of the lid body 1, or when the fastener 32 moves away from the connecting piece 31, the latching part 321 can disengage (see reference). Figure 2 At point B in the middle and Figure 5 In other words, the latching part 321 can disengage from the latch on the flange 51 of the pot body 5, thereby unlocking the pot lid from the pot body 5, making it convenient for the user to open or close the lid. Thus, the latching assembly 3 achieves a locking connection between the pot lid and the pot body 5. The user can directly operate the latching assembly 3 to lock and unlock the pot lid from the pot body 5, making the operation simple. Furthermore, the latching part 321 can directly latch onto the flange 51 of the pot body 5, offering high versatility.

[0053] Specifically, when the latching is required, the user operates the latching assembly 3, causing the latching part 321 to abut against the lower surface of the flange 51. Then, the user applies a force to the connector 31 or the fastener 32, causing the connector 31 to rotate towards the axis of the cover 1, and the fastener 32 to rotate towards the connector 31 with the flange 51 as the fulcrum, thereby latching the latching part 321. When the latching is required to disengage, the user applies a reverse force to the connector 31 or the fastener 32, causing the connector 31 to rotate away from the axis of the cover 1, and the fastener 32 to rotate away from the connector 31 with the flange 51 as the fulcrum, thereby disengaging the latching part 321.

[0054] Furthermore, the mounting base 2 is located in the center of the lid 1 and extends radially along the lid 1. There are two latching components 3, each located at one end of the mounting base 2. On one hand, the two latching components 3 latch onto both sides of the pot body 5, increasing the stability and reliability of the connection between the lid and the pot body 5. On the other hand, the user can operate one latching component 3 with each hand, locking or unlocking the lid and pot body 5 in a single operation.

[0055] Furthermore, the mounting base 2 is provided with a receiving groove 22, which corresponds one-to-one with the buckle assembly 3. The receiving groove 22 is recessed into the upper surface of the mounting base 2 and extends through one end of the mounting base 2 away from the axis of the lid 1. The connector 31 is disposed within the receiving groove 22. When the folding buckle is folded above the mounting base 2, the connector 31 is close to the bottom of the receiving groove 22, a part of the buckle 32 is housed within the receiving groove 22, and the buckle portion 321 is exposed at the end of the receiving groove 22 away from the axis of the lid 1. On the one hand, the receiving groove 22 surrounds the buckle 32 to provide protection, reducing or avoiding the possibility of accidental operation of the buckle 32 during cooking, thereby reducing the risk of accidental unlocking of the lid and the pot body 5 during cooking; on the other hand, the buckle 32 being housed within the receiving groove 22 can reduce the overall volume of the lid and make the appearance of the lid more regular and neat.

[0056] Furthermore, the edge of the lid 1 is provided with a sealing ring 4, and the downward-facing side of the sealing ring 4 is provided with a sealing surface 41. That is, when the lid 1 is closed on the opening of the pot body 5, the downward-facing side of the sealing ring 4 elastically abuts against the opening of the pot body 5, and the sealing ring 4 is deformed by compression along the axial direction of the pot body 5. Through the axial deformation of the sealing ring 4, a flexible floating space is provided between the lid and the pot body 5, which can keep the buckle part 321 in contact with the flange 51 of the pot body 5, increasing the stability of the buckle fixation, and can also increase the axial adaptation range of the buckle part 321, so that the buckle part 321 can be buckled with flanges 51 of different thicknesses. In addition, it can also form a flexible contact between the lid and the pot body 5, preventing noise or damage caused by collision between the lid and the pot body 5.

[0057] Furthermore, the sealing ring 4 includes a first annular portion 42, which fits against the upper surface of the lid 1. The mounting base 2 elastically abuts against the side of the first annular portion 42 opposite to the lid 1. The axial deformation of the first annular portion 42 provides a flexible floating space for the lid itself, allowing the latching portion 321 to maintain contact with the flange 51 of the pot body 5, increasing the stability of the latching fixation, and also increasing the axial adaptation range of the latching portion 321, enabling it to latch with flanges 51 of different thicknesses. In addition, it allows for flexible contact between the mounting base 2 and the lid 1, preventing collisions or scratches between them.

[0058] Furthermore, the fastener 32 includes a main body 322, which is hinged to the end of the connector 31 away from the mounting base 2, and a latching part 321 is located at the end of the main body 322 away from the axis of the lid 1. When the latching part 321 latches, the main body 322 abuts against the upper surface of the mounting base 2. That is, the connector 31 and the main body 322 avoid each other on the upper surface of the mounting base 2, so that the main body 322 directly provides a downward force on the mounting base 2, and the latching part 321 directly provides an upward force on the flange 51 of the pot body 5, increasing the stability and reliability of the connection between the lid and the pot body 5.

[0059] Furthermore, the middle part of the main body 322 is hinged to the end of the connector 31 away from the mounting base 2, and the section of the main body 322 near the axis of the cover 1 is the operating section 3221. That is, a part of the main body 322 extends to the side of the connector 31 near the axis of the cover 1 and forms the operating section 3221. The user moves the buckle assembly 3 by applying external force to the operating member. Since a large distance is formed between the rotation center of the operating section 3221 and the connector 31, and between the operating section 3221 and the fulcrum of the fastener 32, a force-saving lever is formed, making the operation of the buckle assembly 3 more effortless.

[0060] Furthermore, the main body 322 includes a top wall 322a and two opposing first side walls 322b. The first side walls 322b are located on the side of the top wall 322a facing the mounting base 2, and the connector 31 is located between the two first side walls 322b, with both sides of the connector 31 hinged to the two first side walls 322b respectively. This allows both the main body 322 and the connector 31 to form a continuous plate-like structure, thereby ensuring the structural strength of both the main body 322 and the connector 31.

[0061] Furthermore, when the latching part 321 engages, the first side wall 322b abuts against the upper surface of the mounting base 2, and the connector 31 is housed between the main body 322 and the mounting base 2. This allows the connector 31 to be concealed, reducing exposed parts and simplifying the external shape of the lid.

[0062] Specifically, the upper surface of the mounting base 2 includes two opposing protrusions 23, which are located inside the first sidewall 322b. That is, the gap between the two protrusions 23 is smaller than the gap between the two first sidewalls 322b. The connector 31 includes a first segment 311 and a second segment 312 arranged in sequence. The width of the first segment 311 is greater than the width of the second segment 312. The two sides of the first segment 311 are respectively hinged to the two first sidewalls 322b, and the two sides of the second segment 312 are respectively hinged to the two protrusions 23.

[0063] Furthermore, the main body 322 also includes a second side wall 322c, which is disposed on the side of the main body 322 facing the mounting base 2. The second side wall 322c connects the top wall 322a and the two first side walls 322b, thereby supporting and reinforcing the first side walls 322b and preventing abnormalities such as lateral tilting deformation of the side walls.

[0064] Furthermore, the latching part 321 is disposed on the side of the top wall 322a facing the mounting base 2. The latching part 321 connects the top wall 322a and the two first side walls 322b, which not only increases the connection strength between the latching part 321 and the main body 322, but also supports and strengthens the first side walls 322b, preventing abnormalities such as lateral tilting deformation of the first side walls 322b. The latching part 321 extends beyond the height range of the first side walls 322b, that is, the latching part 321 forms a cantilever structure below the main body 322, thereby maintaining a certain degree of elasticity and ensuring that the latching assembly 3 can move normally.

[0065] In addition, this application embodiment also provides a cookware, which includes a pot body 5 and any kind of pot lid provided in this application. The pot body 5 has an outwardly folding flange 51 at the mouth. The pot lid covers the mouth of the pot body 5. When the latching part 321 latches, the latching part 321 latches onto the flange 51.

[0066] 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.
