Description

Technical Field

[0001] This utility model relates to the field of kitchen cooking utensils technology, and in particular to a double-layered pot lid for venting steam and draining water. Background Technology

[0002] Most existing pot lids rely on the gap between the lid and the pot body for venting or pouring water. Some pots have a single vent on the lid, but this cannot meet the need for rapid steam removal during vigorous boiling. A single vent is also ineffective as a drain when excess water needs to be poured out. Furthermore, existing pot lids typically lack circumferential positioning when closed, making them prone to misalignment or sliding during movement or light touches, thus affecting the user experience. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a double-layered pot lid for venting steam and draining water.

[0004] This utility model is achieved through the following technical solution: a double-layered pot lid for venting steam and draining water, installed on a pot body, including an upper lid and a lower lid. The lower lid is installed on the lower side of the upper lid and together with it forms a double-layered lid structure. The periphery of the lower lid has a radially inwardly recessed cross-section. When the double-layered pot lid is placed on the pot opening, the lower side of the lower lid is located inside the pot body below the upper edge of the pot opening, and the outer periphery of the lower lid outside the cross-section rests on the upper edge of the pot opening, forming a gap between the cross-section and the edge of the pot opening.

[0005] The double-layered lid has its lower side extending into the pot, providing reliable circumferential positioning and preventing it from shifting or sliding off. The outer periphery of the lower lid, excluding the cut surface, rests on the upper edge of the pot opening, creating a gap between the outer periphery of the lower lid facing the cut surface and the upper edge of the pot opening. This gap and notch form a stable channel for venting steam and pouring water, allowing users to pour out excess liquid from the pot without fully opening the lid.

[0006] The lower cover has an annular groove structure, with its interior recessed downwards to form a groove. The two side walls of the annular groove fold outwards to form horizontal folded portions, which are fixed to the upper cover. The outer wall of the annular groove, excluding the cut surface, is close to the inner wall of the pot body, and the outer horizontal folded portions, excluding the cut surface, rest on the upper edge of the pot opening. The groove is inserted into the interior of the pot body. The annular groove structure of the lower cover saves material, and the groove forms a circumferential positioning structure.

[0007] The lower cover and the upper cover are fixedly connected together by welding. The welding connection method has the characteristics of high strength, firmness and durability, not easy to fall off and long service life. It can effectively prevent steam from escaping from the gap between the two covers and ensure that all steam is discharged from the gap.

[0008] The cut surface can be a vertical plane, an inclined plane, or a curved surface. When the cut surface is inclined, it can serve as a guide surface, making the water flow more concentrated and less prone to splashing when pouring water; when the cut surface is curved, it matches the contour of the pot body, making the appearance more harmonious and beautiful, and optimizing the guiding effect.

[0009] The cut surface is provided at least once, which can significantly increase the efficiency of steam discharge and water pouring, and is suitable for larger cookware.

[0010] The lower cover is made of stainless steel.

[0011] The top of the upper cover is equipped with a lid handle.

[0012] When there are multiple cut surfaces, evenly distributed cut surfaces help to balance pressure and force.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: The lid has a simple structure, integrating steam venting, water pouring, and positioning functions, achieving functional integration; the double-layered lid has its lower cover extending into the pot body, providing reliable circumferential positioning and preventing the lid from shifting or sliding off; the outer periphery of the lower cover, excluding the cut surface, rests on the upper edge of the pot opening, creating a gap between the outer periphery of the lower cover facing the cut surface and the upper edge of the pot opening. This gap and notch form a stable channel for steam venting and water pouring, allowing users to pour out excess liquid without fully opening the lid, effectively preventing excessive pressure inside the pot from causing liquid overflow, keeping the stove clean, and reducing the risk of burns.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] See Figures 1 to 5 This is a double-layered pot lid for venting steam and draining water. It is installed on the pot body 1 and includes an upper lid body 2 and a lower lid body 3. The lower lid body 3 is installed on the lower side of the upper lid body 2 and together they form a double-layered lid structure. The lower lid body 3 has a radially inwardly recessed cut surface 31 around its periphery. When the double-layered pot lid is placed on the pot opening of the pot body 1, the lower side of the lower lid body 3 is located inside the pot body 1 below the upper edge of the pot opening, and the outer periphery of the lower lid body 3 other than the cut surface 31 rests on the upper edge of the pot opening. A notch 4 is formed between the cut surface 31 and the edge of the pot opening.

[0023] The double-layered lid has its lower cover 3 extending into the pot body 1, providing reliable circumferential positioning and preventing the lid from shifting or sliding off. The outer periphery of the lower cover 3, excluding the cut surface 31, rests on the upper edge of the pot opening, creating a gap 5 between the outer periphery of the lower cover 3, directly opposite the cut surface 31, and the upper edge of the pot opening. This gap 5, together with the notch 4, forms a stable channel for venting steam and pouring water, allowing users to pour out excess liquid from the pot without fully opening the lid.

[0024] The lower cover 3 has an annular groove structure, with its interior recessed downwards to form a groove 32. The two side walls of the annular groove are folded outwards to form horizontal folded portions 33, which are fixed together with the upper cover 2. The outer wall of the annular groove, excluding the cut surface 31, is close to the inner wall of the pot body 1, and the outer horizontal folded portions 33, excluding the cut surface 31, rest on the upper edge of the pot opening. The groove 32 is inserted into the interior of the pot body 1. The lower cover 3 is designed as an annular groove structure, which saves material, and the groove 32 forms a circumferential positioning structure.

[0025] The lower cover 3 and the upper cover 2 are fixedly connected together by welding. The welding connection method has the characteristics of high strength, firmness and durability, not easy to fall off and long service life. It can effectively prevent steam from escaping from the gap between the two covers and ensure that all steam is discharged from the gap 4.

[0026] The cut surface 31 can be a vertical plane, an inclined plane, or a curved surface. When the cut surface 31 is an inclined plane, it can serve as a guide surface, making the water flow more concentrated and less prone to splashing when pouring water; when it is a curved surface, it matches the contour of the pot body 1, making the appearance more harmonious and beautiful, and optimizing the guiding effect.

[0027] At least one cut surface 31 is provided, which can significantly increase the efficiency of steam discharge and water pouring, and is suitable for larger pots.

[0028] The lower cover 3 is made of stainless steel. In this embodiment, the upper cover 2 is also made of stainless steel.

[0029] The top of the upper cover 2 is equipped with a lid handle 6.

[0030] When there are multiple cut surfaces 31, the even distribution of these cut surfaces 31 helps to balance pressure and force.

[0031] Assembly in this embodiment: The upper cover 2 and the lower cover 3 are overlapped and assembled by internal and external welding.

[0032] In this embodiment, the pot body 1 can be a soup pot, a steamer, a wok, or a frying pan, and the pot lid can be adapted to any of them.
