Description

Technical Field

[0001] This utility model relates to the field of cooking utensils technology, and in particular to a pot lid and a pot. Background Technology

[0002] Pressure cookers typically have a vent pipe on the lid to release steam and prevent excessive pressure inside the pot, which could lead to safety hazards. However, during cooking, food may enter the vent pipe with the steam, causing blockage. A blocked vent pipe reduces the efficiency of the pressure relief valve and can even lead to a pressure cooker explosion. While anti-blocking covers are usually installed on the vent pipe to reduce the risk of blockage, existing anti-blocking covers are not very effective. Utility Model Content

[0003] This application provides a pot lid and a pot, the pot lid including an anti-clogging cover, which can improve the anti-clogging effect of the anti-clogging cover.

[0004] This application provides a pot lid and a pot, the pot lid including a lid body and an exhaust valve assembly, the exhaust valve assembly being mounted on the lid body;

[0005] The exhaust valve assembly includes a detachably connected exhaust pipe and an anti-clogging cover. The anti-clogging cover includes a body having a first cavity and a plurality of through holes communicating with the first cavity.

[0006] The length of the body is L, where 20mm ≤ L ≤ 40mm.

[0007] In this solution, during the exhaust process, a large amount of steam will carry the food upward. When the food rises to the body of the anti-clogging cover, larger food particles cannot pass through the through holes, while smaller food particles can enter the first chamber of the anti-clogging cover through the through holes and settle in the first chamber, thereby preventing the food from overflowing through the exhaust pipe.

[0008] In this embodiment, when 20mm≤L≤40mm, the length of the body is moderate, which achieves a good anti-clogging effect without causing inconvenience due to the excessive size of the anti-clogging cover.

[0009] In one possible implementation, the anti-blocking cover is a stamped part, and the thickness of the body is δ, 0.3mm≤δ≤0.4mm.

[0010] In this embodiment of the application, when 0.3mm≤δ≤0.4mm, while achieving a good anti-clogging effect of the anti-clogging cover, it can also reduce the risk of food residue clogging the through hole and reduce the manufacturing cost.

[0011] In one possible implementation, the minimum size of the through hole is D, where 0.8 mm ≤ D ≤ 2 mm.

[0012] In this embodiment of the application, when 0.8mm≤D≤2mm, the anti-clogging cover will not reduce the venting effect of the pot lid, and the anti-clogging performance is good.

[0013] In one possible implementation, the exhaust pipe has an inlet end and an exhaust end, which are located on opposite sides of the lid along its thickness direction. In this embodiment, during use, the liquid inside the pot boils during cooking, and steam enters the first cavity through the through hole and then enters the inlet end of the exhaust pipe, and is subsequently discharged into the air outside the lid through the exhaust end of the exhaust pipe, ensuring the normal operation of the pressure cooker.

[0014] The anti-clogging cover also includes a connecting part connected to the main body, and the connecting part is threadedly connected to the air inlet end.

[0015] In this embodiment, the anti-clogging cover is threadedly connected to the intake end of the exhaust pipe via a connecting part, allowing the anti-clogging cover to be easily removed for cleaning. Furthermore, compared to traditional spring clip or silicone gasket fastening, the threaded connection between the anti-clogging cover and the exhaust pipe avoids the technical problems of spring clip aging, failure, and damage, reducing the frequency of component replacement, lowering manufacturing and maintenance costs, and providing a reliable, easily disassembled, and less prone to damage structure.

[0016] In one possible implementation, the exhaust valve assembly further includes a nut, the intake end being threadedly connected to the nut, and the exhaust pipe being threadedly connected to the nut.

[0017] In this embodiment, when the anti-clogging cover needs cleaning, removing it from the nut prevents the exhaust pipe from falling off the cover because the nut is threadedly connected to the exhaust pipe, allowing the user to remove the anti-clogging cover separately for cleaning. Furthermore, when removing or installing the anti-clogging cover, the connecting part of the cover is threadedly connected to the nut, thus avoiding wear on the exhaust pipe from repeated removal and installation of the anti-clogging cover.

[0018] In one possible implementation, along the thickness direction of the cover, one end of the nut abuts against the cover and the other end abuts against the anti-blocking cover.

[0019] In this embodiment, the nut can restrict the anti-clogging cover from continuing to move along the thickness direction of the pot lid. Furthermore, without changing the length of the existing anti-clogging cover, the nut between the lid and the anti-clogging cover can increase the length of the anti-clogging cover extending into the pot, thereby enhancing the anti-clogging effect.

[0020] In one possible implementation, the thickness W of the nut satisfies: 2mm ≤ W ≤ 4mm. In this embodiment, when the thickness of the nut is 2mm ≤ W ≤ 4mm, it can ensure the limiting and supporting functions without occupying the length of the anti-blocking cover body, thus further ensuring the anti-blocking effect of the anti-blocking cover.

[0021] In one possible implementation, the outer wall of the connecting portion is provided with an anti-slip part. In this embodiment, when installing or removing the anti-clogging cover, the user can rotate the anti-clogging cover via the anti-slip part. The anti-slip part increases the friction, thereby facilitating the detachable design of the exhaust pipe and the anti-clogging cover and improving user convenience.

[0022] In one possible implementation, the exhaust pipe is connected to a stepped portion extending radially outward, the stepped portion abutting against the upper end face of the cover.

[0023] In this embodiment, the exhaust pipe is provided with a stepped portion that abuts against the upper end face of the lid, which can restrict the downward movement of the exhaust pipe. At the same time, the lower end of the lid abuts against the nut, which can restrict the upward movement of the exhaust pipe. Therefore, the stepped portion and the nut can restrict the movement of the exhaust pipe relative to the lid along the thickness direction of the lid, thereby preventing the exhaust pipe from detaching from the lid.

[0024] In one possible implementation, the cookware includes a pot body and a lid, wherein the lid is capable of closing onto the pot body. Specifically, the lid can be a pressure cooker lid, and the cookware can be a pressure cooker.

[0025] 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

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] In one specific embodiment, this application provides a pot lid and a cookware, the cookware including a pot body and a pot lid, the pot lid being able to close onto the opening of the pot body, thereby sealing the inner cavity of the pot body. (Reference) Figure 1 As shown, the pot lid includes a lid body 1 and an exhaust valve assembly 2, which is mounted on the lid body 1. Specifically, this pot lid can be a pressure cooker lid, and the cookware can be a pressure cooker.

[0050] refer to Figure 3As shown, the exhaust valve assembly 2 includes a detachably connected exhaust pipe 21 and an anti-clogging cover 22. The anti-clogging cover 22 includes a body 221, which has a first cavity 221a and multiple through holes 221b communicating with the first cavity 221a. The first cavity 221a is also connected to the exhaust pipe 21. During use, as the temperature rises, the liquid in the pot boils. The boiling generates a large amount of steam, increasing the pressure inside the pot. This steam can be discharged through the anti-clogging cover 22 and the exhaust pipe 21, preventing safety issues caused by excessive pressure inside the pot. During the venting process, a large amount of steam carries food upwards. When the food rises to the body 221 of the anti-clogging cover 22, larger food particles cannot pass through the through holes 221b, while smaller food particles enter the first cavity 221a of the anti-clogging cover 22 through the through holes 221b and can deposit there, preventing the food from overflowing through the exhaust pipe 21.

[0051] The length of the body 221 of the anti-blocking cover 22 with through hole 221b is L, 20mm≤L≤40mm. For example, the length L can be 20mm, 25mm, 30mm, 40mm, etc.

[0052] In this embodiment, when the length L of the anti-clogging cover 22 body 221 is too small, the size of the part of the anti-clogging cover 22 used to set the through hole 221b is too small, the contact area with the food is too small, and the volume of the first cavity 221a of the anti-clogging cover 22 is also relatively small. This causes the first cavity 221a inside the anti-clogging cover 22 to be filled very quickly, posing a risk that food may enter the exhaust pipe 21 from the first cavity 221a and overflow. As a result, the anti-clogging effect of the anti-clogging cover 22 is poor, affecting the use of the cookware and even causing discomfort to the user. This presents a safety hazard. When the length L of the anti-clogging cover 22 body 221 is too large, the end of the body 221 extending into the pot is too large, making it easy for it to come into direct contact with the food being cooked in the pot. This makes it easier for food residue to enter the first cavity 221a through the through hole 221b, thus affecting the anti-clogging effect of the anti-clogging cover 22. Furthermore, when the anti-clogging cover 22 is too large, the body 221 of the anti-clogging cover 22 is easily bumped and damaged during transportation or storage of the pot lid, and it also results in a larger storage space required for the pot lid. In the embodiment of this application, when 20mm≤L≤40mm, the length of the body 221 is moderate, achieving a good anti-clogging effect of the anti-clogging cover 22 without causing inconvenience due to the excessive size of the anti-clogging cover 22.

[0053] In one specific embodiment, reference is made to... Figure 3As shown, the exhaust pipe 21 has an air inlet end 211 and an exhaust end 212. The air inlet end 211 and the exhaust end 212 are located on both sides of the lid 1 along the thickness direction. When the cooker is in use, the liquid in the pot boils during the cooking process. The steam enters the first cavity 221a through the through hole and then enters the air inlet end 211 of the exhaust pipe 21. It is then discharged to the air outside the lid 1 through the exhaust end 212 of the exhaust pipe 21, thus ensuring the normal operation of the pressure cooker.

[0054] In this embodiment, the anti-clogging cover 22 also includes a connecting part 222 connected to the main body 221. The connecting part 222 is threadedly connected to the air intake end 211, that is, the anti-clogging cover 22 is threadedly connected to the air intake end 211 of the exhaust pipe 21 through the connecting part 222, so that the anti-clogging cover 22 can be easily removed for cleaning. In addition, when the anti-clogging cover 22 is threadedly connected to the exhaust pipe 21, compared with the traditional spring clip fastening or silicone gasket fastening, it avoids the technical problems of spring clips being prone to aging or even failure and damage, reduces the frequency of parts replacement, lowers manufacturing and maintenance costs, and has a reliable structure that is easy to disassemble and not easily damaged.

[0055] In other embodiments, the anti-clogging cover 22 and the exhaust pipe 21 can also be detachably connected in other ways, such as by snap-fit. Specifically, the anti-clogging cover 22 may be provided with a first snap-fit ​​portion, and the exhaust pipe 21 may be provided with a second snap-fit ​​portion. When the anti-clogging cover 22 needs to be used, the anti-clogging cover 22 and the exhaust pipe 21 are snapped together by the first snap-fit ​​portion and the second snap-fit ​​portion. When the anti-clogging cover 22 needs to be cleaned, the first snap-fit ​​portion and the second snap-fit ​​portion are released, and the anti-clogging cover 22 is removed.

[0056] In one specific embodiment, reference is made to... Figure 3 As shown, the outer wall of the connecting portion 222 of the anti-clogging cover 22 is provided with an anti-slip part. When installing or removing the anti-clogging cover 22, the user can rotate the anti-clogging cover 22 through the anti-slip part. The anti-slip part can increase the friction, thereby helping to realize the detachable design of the exhaust pipe 21 and the anti-clogging cover 22, which helps the user to operate conveniently.

[0057] The design of the anti-slip part includes, but is not limited to, setting external thread shapes, raised ribs, raised dots, etc.

[0058] In one specific embodiment, reference is made to... Figure 4As shown, the exhaust valve assembly may also include a nut 23, with the air inlet end 211 of the exhaust pipe 21 threadedly connected to the nut 23, and the exhaust pipe 21 threadedly connected to the nut 23. Therefore, the exhaust pipe 21 and the anti-clogging cover 22 are detachably connected via the nut 23, and the exhaust pipe 21 is mounted on the cover 1 via the nut 23. When the anti-clogging cover 22 needs cleaning, removing it from the nut 23 prevents the exhaust pipe 21 from falling off the cover 1, allowing the user to remove the anti-clogging cover 22 separately for cleaning. Furthermore, when removing or installing the anti-clogging cover 22, the connecting part 222 of the anti-clogging cover 22 is threadedly connected to the nut 23, thereby preventing wear on the exhaust pipe 21 from repeated removal and installation of the anti-clogging cover 22.

[0059] In other embodiments, the exhaust pipe 21 and the anti-clogging cover 22 can also be directly threaded together. For example, the air inlet end 211 of the exhaust pipe 21 can be provided with external threads, and the connecting part 222 of the anti-clogging cover 22 can be provided with internal threads, so that the air inlet end 211 of the exhaust pipe 21 and the connecting part 222 of the anti-clogging cover 22 can be directly threaded together.

[0060] In one specific embodiment, reference is made to... Figure 4 As shown, along the thickness direction of the lid, one end of the nut 23 abuts against the lid body 1, and the other end abuts against the anti-blocking cover 22. At this time, the nut 23 can restrict the anti-blocking cover 22 from continuing to move along the thickness direction of the lid. Moreover, without changing the existing length of the anti-blocking cover 22, the nut 23 between the lid body 1 and the anti-blocking cover 22 can increase the length of the anti-blocking cover 22 extending into the pot body, thereby enhancing the anti-blocking effect.

[0061] In one specific embodiment, reference is made to... Figure 4 As shown, the exhaust pipe 21 is connected to a stepped portion 211a that extends radially outward, and the stepped portion 211a abuts against the upper end surface of the cover 1.

[0062] In this embodiment, the exhaust pipe 21 is provided with a stepped portion 211a that abuts against the upper end surface of the cover 1, which can restrict the exhaust pipe 21 from moving downward. At the same time, the lower end of the cover 1 abuts against the nut 23, which can restrict the exhaust pipe 21 from moving upward. Therefore, the stepped portion 211a and the nut 23 can restrict the exhaust pipe 21 from moving relative to the cover 1 along the thickness direction of the lid, thereby preventing the exhaust pipe 21 from detaching from the cover 1.

[0063] In one specific embodiment, reference is made to... Figure 4 As shown, the thickness W of nut 23 satisfies: 2mm ≤ W ≤ 4mm. For example, W can be 2mm, 2.4mm, 2.8mm, 3.2mm, 4mm, etc. That is, nut 23 is a thin nut.

[0064] When the thickness of nut 23 is too large, it will affect the length of the anti-clogging cover 22, occupying the length of the anti-clogging cover 22 body 221 and affecting the anti-clogging effect. When the thickness of nut 23 is too small, its strength is insufficient, and it is prone to deformation, reducing its support and limiting effect. In this embodiment, when the thickness of nut 23 is 2mm≤W≤4mm, it can ensure the limiting and supporting functions without occupying the length of the anti-clogging cover 22 body 221, further ensuring the anti-clogging effect of the anti-clogging cover 22.

[0065] In the above embodiments, the anti-clogging cover 22 is a stamped part. When the anti-clogging cover is formed by stamping, the thickness of the body 221 of the anti-clogging cover 22 can be reduced. In one specific embodiment, the thickness of the body 221 of the anti-clogging cover 22 is δ, 0.3mm≤δ≤0.4mm. For example, the thickness δ can be 0.3mm, 0.32mm, 0.356mm, 0.388mm, 0.4mm, etc.

[0066] In this embodiment, when the thickness δ of the anti-clogging cover 22 body 221 is too small, the strength of the anti-clogging cover 22 body 221 will be insufficient, resulting in a thin and brittle anti-clogging cover 22, leading to a shorter service life. Furthermore, when a through hole 221b is provided on the anti-clogging cover 22 body 221, it is prone to damage, causing material waste and increasing manufacturing costs. When the thickness δ of the anti-clogging cover 22 body 221 is too large, it will also cause material waste and result in an excessively deep through hole 221b, making it easy for food residue to clog the through hole 221b and difficult to clean. However, in this embodiment, when 0.3mm≤δ≤0.4mm, while achieving a good anti-clogging effect, it can also reduce the risk of food residue clogging the through hole 221b and lower manufacturing costs.

[0067] In this embodiment, the anti-blocking cover 22 is manufactured by stamping, which is simpler and more efficient than machining.

[0068] In one specific embodiment, reference is made to... Figure 2 As shown, the minimum dimension of through hole 221b is D, where 0.8mm ≤ D ≤ 2mm. For example, D can be 0.8mm, 1.2mm, 1.5mm, 2mm, etc. (Reference) Figure 2 and Figure 4 As shown, when the through hole 221b is a circular hole, the minimum dimension D refers to the diameter of the circular hole; when the through hole 221b is an oblong hole, the minimum dimension D refers to the width of the oblong hole. In other embodiments, the shape of the through hole 221b includes, but is not limited to, closed shapes such as circles, ellipses, and rectangles, i.e., D refers to the minimum dimension of the through hole 221b in its specific embodiment.

[0069] In this embodiment, when the minimum size D of the through hole 221b of the anti-clogging cover 22 is too small, steam cannot quickly enter the first cavity 221a and be discharged from the exhaust pipe 21, affecting the exhaust effect and easily causing excessive pressure inside the pot, thus affecting safety. Furthermore, if the through hole 221b is too small, the drill bit is prone to breakage during processing, increasing processing difficulty. When the minimum size D of the through hole 221b of the anti-clogging cover 22 is too large, larger food particles can pass through, thus affecting the anti-clogging effect of the anti-clogging cover 22. However, in this embodiment, when 0.8mm ≤ D ≤ 2mm, the anti-clogging cover 22 does not reduce the exhaust effect of the pot lid and has good anti-clogging performance.

[0070] Furthermore, in related technologies, the through holes 221b of the anti-clogging cover 22 are typically manufactured by machining. However, machining the through holes 221b of the anti-clogging cover 22 requires machining them one pair at a time, and the minimum size for machining is generally not less than 2 mm, resulting in poor anti-clogging effect of the anti-clogging cover 22. In the embodiment of this application, the through holes 221b of the anti-clogging cover 22 are formed in one step by stamping, which allows for the machining of smaller through holes 221b, thereby improving the anti-clogging effect of the anti-clogging cover 22.

[0071] The above descriptions are merely specific implementations of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. 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. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
