Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, and in particular to a valve assembly, a container lid, and a cooking container. Background Technology

[0002] Pressure cookers have become an indispensable cooking appliance in our kitchens due to their numerous advantages, such as rapid cooking, high cooking temperature, and good food taste. Pressure cookers are equipped with a check valve.

[0003] When a clamp-type pressure cooker is not properly engaged, the clamps inside will prevent the check valve from rising. During the venting process, food inside the cooker may adhere to the check valve, blocking its gas flow path. Utility Model Content

[0004] This application provides a valve assembly, a container lid, and a cooking container, designed to reduce the risk of valve assembly blockage.

[0005] This application provides a valve assembly in a first aspect for a cooking container, the cooking container including a lid and a body capable of being closed, the valve assembly comprising:

[0006] Mounting base;

[0007] A valve body, which is mounted on the mounting base, and a portion of the structure of the valve body can extend from the lower end of the mounting base to the outside of the mounting base;

[0008] A protective cover is mounted on the mounting base, and the portion of the valve body extending out of the mounting base is located within the protective cover.

[0009] In this embodiment, when the container lid is closed on the container body, the portion of the valve body located inside the cooking container is housed within a protective cover. The protective cover surrounds the valve body, preventing food from overflowing and spraying onto the valve body. This reduces the risk of food and broth adhering to the gas passages of the valve body, blocking them, and causing excessive pressure buildup inside the cooking container, potentially leading to an explosion.

[0010] In one possible design, the protective cover and the mounting base are detachably connected.

[0011] In this embodiment, the protective cover and the mounting base are detachably connected, so that the protective cover can be removed and the food attached to the protective cover can be cleaned, making it convenient for users.

[0012] In one possible design, the protective cover is provided with a snap-fit ​​part, and the mounting base is provided with a mating part, wherein the snap-fit ​​part and the mating part snap-fit ​​together.

[0013] In this embodiment, the protective cover and the mounting base are connected by a snap-fit ​​mechanism, facilitating the assembly and disassembly of the protective cover and the mounting base. Furthermore, the connection between the protective cover and the mounting base is achieved through their own structures, eliminating the need for additional auxiliary parts; the structure is simple and easy to assemble and disassemble.

[0014] In one possible design, the snap-fit ​​portion is a protrusion of part of the protective cover protruding towards the mounting base, and the mating portion is a groove of the mounting base recessed inward.

[0015] Both the snap-fit ​​portion and the mating portion are provided in at least two forms, and the at least two snap-fit ​​portions and the at least two mating portions are evenly distributed along the circumference of the valve assembly.

[0016] In this embodiment of the application, by providing at least two snap-fit ​​parts and at least two mating parts to cooperate, the reliability of the connection between the protective cover and the mounting base is ensured.

[0017] In one possible design, the snap-fit ​​portion is a protrusion facing the mounting base, and at least two snap-fit ​​portions are provided, with at least two snap-fit ​​portions evenly distributed along the circumference of the valve assembly;

[0018] The mating part is an annular groove that is recessed inward along the circumference of the mounting base.

[0019] In this embodiment, the mating part is set as an annular groove structure. When installing the protective cover and the mounting base, it is not necessary to adjust the angle of the protective cover to make the snap-fit ​​part opposite to the mating part, nor is it necessary to insert the snap-fit ​​part into the corresponding mating part. This facilitates the snap-fit ​​part and the mating part to snap together and improves the user's convenience.

[0020] In one possible design, the protective cover is further provided with an opening along the axial direction of the valve assembly, the opening extending inward along the edge of the protective cover;

[0021] Along the circumference of the valve assembly, the opening is located on both sides of each of the snap-fit ​​portions.

[0022] In this embodiment, openings are provided on both sides of the snap-fit ​​portion, making the portion between the openings elastic and providing expansion space for the snap-fit ​​portion. When the protective cover mates with the mounting base, external force compresses the opening of the protective cover, increasing its opening degree and pushing the snap-fit ​​portion of the protective cover to a position opposite to the mating portion. When the snap-fit ​​portion and the mating portion are positioned opposite each other, the opening retracts due to the elasticity of the protective cover itself, allowing the snap-fit ​​portion to insert into the mating portion. A tight fit is maintained between the snap-fit ​​portion and the mating portion, ensuring the reliability of the connection between them.

[0023] In one possible design, the snap-fit ​​portion is provided with a side wall and a bottom wall, the side wall being provided with a first through hole and the bottom wall being provided with a second through hole.

[0024] In this embodiment, both the first through hole and the second through hole are connected to the accommodating space of the protective cover, so that the gas in the cooking container can flow into the accommodating space through the first through hole and the second through hole, thereby driving the valve body to move to pressurize the cooking container or discharge it outward from the gas flow channel of the valve body.

[0025] In one possible design, the valve body is a stop valve; or, the valve body is an exhaust valve.

[0026] In this embodiment of the application, taking the valve body as an example of a stop valve, a protective cover is set on the outside of the stop valve. Even if the clamps on the container lid are not properly engaged and the stop valve cannot be raised to the second position, when the cooking container is venting, the protective cover will prevent the food overflowing upwards from the cooking container from adhering to the stop valve, so as to avoid the food blocking the stop valve, ensure that the stop valve can vent outwards, reduce the risk of explosion due to excessive gas pressure in the cooking container, and thus ensure the safety of the user.

[0027] In a second aspect, this application provides a container lid, the container lid comprising:

[0028] Cover;

[0029] A valve assembly, which is mounted on the cover, is the valve assembly described above.

[0030] In this embodiment of the application, since the valve assembly has the above-mentioned technical effects, the container cover containing the valve assembly should also have the corresponding technical effects, which will not be described in detail here.

[0031] This application provides a cooking container in a third aspect, the cooking container comprising:

[0032] container body;

[0033] A container lid, which is capable of covering the container body, and the container lid is the container lid described above.

[0034] In this embodiment of the application, since the valve assembly has the above-mentioned technical effects, the cooking container containing the valve assembly should also have the corresponding technical effects, which will not be elaborated here.

[0035] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0055] 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

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0060] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described 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 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.

[0061] This embodiment provides a cooking container (not shown in the figure), which can be a pressure cooker. The cooking container includes a container body (not shown in the figure) and a container lid 2, which can be closed onto the container body.

[0062] like Figure 1 The diagram shows a container lid. The container lid 2 includes a lid body 21 and a valve assembly 1, which is installed on the lid body 21.

[0063] Figure 2 This is a cross-sectional view of the container cover along the valve assembly section. The valve assembly 1 includes a mounting base 11, a valve body 12, and a protective cover 13. The valve body 12 is mounted on the mounting base 11, and the mounting base 11 is mounted on the cover body 21. A portion of the valve body 12 extends from the lower end of the mounting base 11 to the outside of the mounting base 11 and is disposed inside the container body. The protective cover 13 is mounted on the mounting base 11 and has a receiving space. The portion of the valve body 12 extending out of the mounting base 11 is located within the receiving space of the protective cover 13, and the valve body 12 is movable within the receiving space.

[0064] In this embodiment, when the container lid 2 is closed onto the container body, the portion of the valve body 12 located inside the cooking container is housed within the protective cover 13. The protective cover 13 surrounds the valve body 12, enabling it to act as a barrier, preventing food from overflowing and spraying onto the valve body 12. This reduces the risk of food and broth adhering to the gas passage of the valve body 12, blocking the gas passage, and preventing the gas inside the cooking container from escaping. This also reduces the risk of excessive gas pressure inside the cooking container leading to an explosion, thus ensuring user safety.

[0065] In some embodiments, the protective cover 13 and the mounting base 11 may be detachably connected.

[0066] In this embodiment, the protective cover 13 and the mounting base 11 are detachably connected so that the protective cover 13 can be removed and the food attached to the protective cover 13 can be cleaned, making it convenient for users to use.

[0067] Alternatively, in some embodiments, the protective cover 13 and the mounting base 11 may be fixedly connected. The specific configuration can be determined according to actual circumstances, and this embodiment does not impose any limitations.

[0068] like Figure 3 As shown Figure 2 Enlarged schematic diagram of part A: The protective cover 13 is provided with a snap-fit ​​part 131, and the mounting base 11 is provided with a mating part 111. The snap-fit ​​part 131 and the mating part 111 snap-fit ​​together.

[0069] In this embodiment, the snap-fit ​​part 131 is located near the edge of the protective cover 13. The protective cover 13 and the mounting base 11 are connected by the snap-fit ​​part 131 and the mating part 111, which facilitates the assembly and disassembly of the protective cover 13 and the mounting base 11. Furthermore, the connection between the protective cover 13 and the mounting base 11 is achieved through their own structures, without the need for other auxiliary parts, resulting in a simple structure and convenient assembly and disassembly.

[0070] Specifically, in some embodiments, the snap-fit ​​portion 131 is a protrusion of part of the protective cover 13 that protrudes towards the mounting base 11, and the mating portion 111 is a recess of the mounting base 11 that is recessed inward. There are at least two snap-fit ​​portions 131 and at least two mating portions 111, and the at least two snap-fit ​​portions 131 and the at least two mating portions 111 are evenly distributed along the circumference of the valve assembly 1.

[0071] The number of snap-fit ​​parts 131 and mating parts 111 can be set to 2, 3, 4, etc.

[0072] For example, there can be four snap-fit ​​parts 131 and four mating parts 111, all of which are evenly distributed along the circumference of the valve assembly 1. By setting four snap-fit ​​parts 131 and four mating parts 111 for snap-fit ​​engagement, the reliability of the connection between the protective cover 13 and the mounting base 11 is ensured.

[0073] Alternatively, please refer to the following: Figure 4 and Figure 5 , Figure 4 and Figure 5 The diagram shows the structure of valve assembly 1. The snap-fit ​​portion 131 is a protrusion facing the mounting base 11. At least two snap-fit ​​portions 131 are provided, and the at least two snap-fit ​​portions 131 are evenly distributed along the circumference of valve assembly 1. The mating portion 111 is an annular groove that is recessed inward along the circumference of mounting base 11.

[0074] The number of snap-fit ​​parts 131 can be set to 2, 3, 4, etc.

[0075] In this embodiment, by setting the mating part 111 as an annular groove structure, when installing the protective cover 13 and the mounting base 11, it is not necessary to adjust the angle of the protective cover 13 so that the snap-fit ​​part 131 is opposite to the mating part 111, and it is not necessary to insert the snap-fit ​​part 131 into the corresponding mating part 111. This facilitates the snap-fit ​​of the snap-fit ​​part 131 and the mating part 111, and improves the convenience of use for users.

[0076] Alternatively, in some embodiments, the snap-fit ​​portion 131 and the mating portion 111 may be other detachable mating structures, which are not limited in this embodiment.

[0077] Furthermore, the snap-fit ​​portion 131 is provided with a guide surface, which can guide the snap-fit ​​portion 131 to extend into or disengage from the mating portion 111.

[0078] Please continue to refer to the reference. Figure 4 and Figure 5 In some embodiments, the protective cover 13 is further provided with an opening 132, which extends inward along the edge of the protective cover 13 along the axial direction of the valve assembly 1. Along the circumferential direction of the valve assembly 1, the opening 132 is located on both sides of each latching portion 131.

[0079] In this embodiment, openings 132 are provided on both sides of the snap-fit ​​portion 131, making the portion between the openings 132 elastic, providing expansion space for the snap-fit ​​portion 131. When the protective cover 13 is engaged with the mounting base 11, the external force compresses the opening 132 of the protective cover 13 to increase its opening degree, pushing the snap-fit ​​portion 131 of the protective cover 13 to a position opposite to the mating portion 111. When the snap-fit ​​portion 131 and the mating portion 111 are positioned opposite each other, the opening 132 retracts due to the elasticity of the protective cover 13 itself, allowing the snap-fit ​​portion 131 to be inserted into the mating portion 111. The snap-fit ​​portion 131 and the mating portion 111 maintain a tight fit, ensuring the reliability of the connection between them.

[0080] The protective cover 13 can be made of materials such as stainless steel or aluminum alloy.

[0081] Please refer to the reference. Figure 2 and Figure 4 The snap-fit ​​part 131 is provided with a side wall 133 and a bottom wall 134. The side wall 133 is provided with a first through hole 133a and the bottom wall 134 is provided with a second through hole 134a. Both the first through hole 133a and the second through hole 134a are connected to the receiving space of the protective cover 13, so that the gas in the cooking container can flow into the receiving space through the first through hole 133a and the second through hole 134a, thereby pushing the valve body 12 to move to pressurize the cooking container or to discharge it outward from the gas channel of the valve body 12.

[0082] In some embodiments, the valve body 12 can be a stop valve, an exhaust valve, a safety valve, etc. Alternatively, the valve body 12 can also be other valves installed on a cooking container to perform an exhaust function; this embodiment is not limited to these specific applications.

[0083] Taking the valve body 12 as an example of a check valve, the check valve is movably mounted on the mounting base 11. When there is insufficient pressure inside the cooking container, the check valve is in the first position under its own weight, at which point the user can rotate the container lid 2. When there is sufficient pressure inside the cooking container, the check valve is pushed upwards and moved to the second position. When the check valve is in the second position, it can restrict the rotation of the container lid 2, thereby preventing the user from opening the container lid 2 when there is pressure inside the cooking container, thus ensuring the user's operation and installation.

[0084] In this embodiment, by setting a protective cover 13 to cover the outside of the check valve, even if the clamps on the container lid 2 are not properly engaged and the check valve cannot be raised to the second position, when the cooking container is venting, the protective cover 13 will prevent the food overflowing upwards from the cooking container from adhering to the check valve, so as to avoid the food blocking the check valve, ensure that the check valve can vent outwards, reduce the risk of excessive gas pressure in the cooking container causing an explosion, and thus ensure the safety of the user.

[0085] In this embodiment, when the valve body 12 in the valve assembly 1 is a valve body such as an exhaust valve or a safety valve, the function of the protective cover 13 and the connection structure between the protective cover 13 and the mounting base 11 can be referred to the above, and will not be repeated here in this embodiment.

[0086] 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.
