Description

Technical Field

[0001] This utility model relates to the field of pot lid technology, and in particular to a pot lid that is less likely to overflow. Background Technology

[0002] When cooking porridge in a pot, after the water boils, you should turn the heat down to a simmer. However, the heat shouldn't be too low, otherwise the porridge will be essentially soaked, lacking consistency and flavor. At this heat, if the lid is completely sealed, the temperature above the water surface will remain high. The bubbles in the porridge will not burst or burst less frequently, leading to an accumulation of bubbles that eventually cause the porridge to overflow. Therefore, after boiling and turning the heat down, you should lift the lid and tilt it over the pot, securing it at the top rim with one side above the rim and the other below. This creates a gap between the lid and the sides of the pot, lowering the temperature above the water surface and preventing overflow. However, the friction between the lid and the pot is low, and at some point during cooking, the tilted lid may tip over due to gravity, reducing or eliminating the gap and causing the porridge to overflow. If the lid is completely removed, the pot cannot maintain the required boiling level over a low flame, requiring a higher heat and wasting gas. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pot lid that is less prone to overflowing, addressing the aforementioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pot lid that is not easy to overflow, including a lid body, the lid body is provided with at least one hollow part, the lid body is provided with a through hole in the center, the liner is provided with a connecting post in the center, the liner is provided with at least one cover plate on the side, the cover plate is located below the lid body, the connecting post passes through the through hole from bottom to top and is connected to a handle, and a spring is provided between the handle and the lid body.

[0005] To further optimize this technical solution, the number of the hollowed-out parts is four and they are symmetrically distributed about the axis of the cover, and the number of the cover plates is four and they are symmetrically distributed about the axis of the lining.

[0006] To further optimize this technical solution, the projection of the hollowed-out portion onto the horizontal plane is fan-shaped.

[0007] To further optimize this technical solution, the top of the connecting column is provided with a threaded part, and the gripper is provided with a threaded hole that mates with the threaded part.

[0008] To further optimize this technical solution, the lower part of the connecting column is a frustum, the diameter of the lower bottom surface of the frustum is larger than the diameter of its upper bottom surface, and the lower part of the through hole is provided with a tapered part that mates with the frustum.

[0009] To further optimize this technical solution, the middle part of the connecting column is a guide column, and the diameter of the guide column is smaller than the diameter of the through hole.

[0010] Compared with the prior art, the present invention has the following advantages: the cover is provided with a hollow part, and a through hole is provided in the center of the cover. The connecting post on the liner passes through the through hole and is connected to a handle. A spring is provided between the handle and the cover. The liner can be easily rotated after pressing down the handle, so as to adjust the degree of obstruction of the hollow part by the cover plate on the liner as needed. The liner will not rotate on its own after releasing the handle, thus preventing overflow. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0017] Detailed implementation method: combined with Figure 1-4As shown, a pot lid that prevents overflow includes a lid body 1 with at least one hollowed-out portion 11 and a through hole 12 in the center. A connecting post 42 is located in the center of a liner 4, and at least one cover plate 41 is provided on the side of the liner 4. The cover plate 41 is located below the lid body 1 and can fit against the bottom surface of the lid body 1, completely covering the hollowed-out portion 11. The connecting post 42 passes through the through hole 12 from bottom to top and is connected to a handle 2. A spring 3 is provided between the handle 2 and the lid body 1. When the spring 3 is in a compressed state, it can push the handle 2 upward to make the cover plate 41 fit against the bottom surface of the lid body 1. Rotating the handle 2 can rotate the liner 4, thereby adjusting the degree of coverage of the hollowed-out portion 11 by the cover plate 41.

[0018] Preferably, the number of the perforated portions 11 is four and they are symmetrically distributed about the axis of the cover 1, and the number of the cover plates 41 is four and they are symmetrically distributed about the axis of the liner 4.

[0019] Preferably, the projection of the hollow portion 11 onto the horizontal plane is fan-shaped, making the side of the hollow portion 11 away from the through hole 12 wider.

[0020] Specifically, the top of the connecting column 42 is provided with a threaded part 423, and the gripper 2 is provided with a threaded hole that mates with the threaded part 423, which facilitates the installation of the gripper 2.

[0021] Furthermore, the lower part of the connecting column 42 is a frustum 421, the diameter of the lower bottom surface of the frustum 421 is larger than the diameter of its upper bottom surface, and the lower part of the through hole 12 is provided with a conical part that cooperates with the frustum 421. When the gripper 2 is pressed down, the side surface of the frustum 421 will separate from the inner side surface of the conical part, thereby reducing the friction.

[0022] Furthermore, the middle part of the connecting post 42 is a guide post 422, the diameter of which is smaller than the diameter of the through hole 12, and the friction between the two is very small or even almost non-existent.

[0023] When in use, the lid is placed on the pot and the cover plate 41 completely covers the hollow part 11. After boiling, the gas stove is turned to low heat. Then, the handle 2 is pressed down, and the cover plate 41 separates from the lid 1. The side of the truncated cone part 421 separates from the inner side of the conical part. Then, the handle 2 is rotated to adjust the degree to which the hollow part 11 is covered by the cover plate 41, so that it will not overflow and save gas. Then, the handle 2 is released. The cover plate 41 and the lid 1 come into contact and there is a certain friction between them. The liner 4 will not rotate on its own.

[0024] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
