Description

Technical Field

[0001] This utility model relates to the field of kitchen cookware technology, and in particular to a high-legged, sealed glass pot lid. Background Technology

[0002] As a core component of kitchen cookware, the pot lid plays a crucial role in creating a sealed cooking space, and its performance directly affects heat retention, energy efficiency, and cooking safety. While traditional pure glass pot lids offer the advantage of allowing visibility of the cooking process, they suffer from two major technical bottlenecks: First, the inherent smoothness of glass results in insufficient sealing at the contact surface with the pot, making it impossible to maintain an ideal micro-pressure environment. This not only causes 20%-30% heat loss but also limits its application in stewing and braising. Second, the rigid glass edges lack effective fixing structures, making them prone to displacement or even slippage when subjected to steam impact or external force, posing a risk of burns.

[0003] Existing improvement solutions enhance sealing by adding a fixed silicone sealing ring to the glass edge, but this exposes a new technical defect: the fixed sealing structure cannot achieve adaptive pressure adjustment under boiling conditions, and the lid is prone to detachment when the steam pressure inside the pot exceeds 5 kPa. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a high-footed, sealed glass pot lid that can achieve adaptive pressure adjustment.

[0005] This utility model is achieved by the following method: a high-footed sealed glass pot lid, including a glass pot lid body, a steel ring is provided on the outer side of the glass pot lid body, a support ring is provided on the lower surface of the steel ring, a plurality of first vent holes are provided at both the left and right ends of the support ring, a rotating ring is rotatably connected to the outer side of the support ring via a rotating component, an extension portion extends outward from the lower surface of the rotating ring, a silicone ring is provided on the lower surface of the extension portion, and a plurality of second vent holes corresponding to the first vent holes are provided at both the left and right ends of the rotating ring.

[0006] Furthermore, the rotating component includes a rotating protrusion and an annular groove. The rotating protrusion is provided at both the upper and lower ends of the outer side of the supporting ring, and the annular groove that cooperates with the rotating protrusion is provided at both the upper and lower ends of the inner side of the rotating ring. Multiple balls are embedded at equal intervals on the rotating protrusion.

[0007] The beneficial effects of this utility model are as follows: This utility model achieves dynamic adjustment of steam pressure through the rotating connection structure between the rotating ring and the supporting ring, combined with the corresponding design of the first and second air outlets; the detachable design of the steel ring and the extension makes it easy to replace them separately after aging, and has the advantages of improving sealing performance, realizing adaptive pressure adjustment, extending service life and facilitating the replacement of the sealing structure. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model.

[0009] Figure 2 This is the front view of the present invention. Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] Please see Figure 1 and Figure 2 As shown, this utility model provides an embodiment: a high-footed sealing glass pot lid, including a glass pot lid body 1, a steel ring 2 is provided on the outer side of the glass pot lid body 1, a support ring 3 is provided on the lower surface of the steel ring 2, a plurality of first vent holes 31 are provided at both the left and right ends of the support ring 3, a rotating ring 5 is rotatably connected to the outer side of the support ring 3 via a rotating member 4, an extension portion 51 extends outward from the lower surface of the rotating ring 5, a silicone ring 52 is provided on the lower surface of the extension portion 51, and a plurality of second vent holes 53 corresponding to the first vent holes 31 are provided at both the left and right ends of the rotating ring 5.

[0012] The components are as follows: The steel ring refers to the metal reinforcement structure surrounding the outer side of the glass lid body. It can be a stainless steel ring welded and fixed to enhance the overall structural strength. The support ring is the annular base connected below the steel ring. It can be a stamped metal ring, providing a mounting base for the rotating ring. The first vent is a through hole distributed circumferentially along the support ring. It can be a round hole with a diameter of 2-5 mm, used to establish a gas flow path. The rotating ring is an annular component connected to the support ring via a rotating part. It can be a metal ring with an inner groove, allowing for rotatable connection with the support ring. The extension is a flange structure extending downwards from the rotating ring. It can be an annular boss with a width of 3-8 mm, used to fix the silicone ring. The second vent is a hole distributed circumferentially along the rotating ring. It can be a rectangular hole with the same number as the first vent, and its alignment with the first vent can be adjusted by rotation.

[0013] Specifically, when the rotating ring is in its initial position, the second vent is completely misaligned with the first vent, and the silicone ring fits tightly against the edge of the pot, creating a complete seal. When the pressure inside the pot exceeds a threshold, manually rotating the glass lid causes the second vent to partially overlap with the first vent, forming a stepped exhaust channel to release excess steam. The greater the rotation angle, the larger the overlap area between the two vents, and the higher the exhaust efficiency.

[0014] Through the above technical solution, this application achieves active pressure regulation inside the pot while maintaining basic sealing performance. During the boiling stage of the soup, the user can quickly establish an venting channel by rotating the pot, avoiding the risk of the lid bursting due to excessive pressure. In scenarios requiring pressure maintenance, such as simmering or stewing, the fully closed vent can maintain a micro-pressure environment inside the pot, improving heat utilization efficiency.

[0015] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the rotating component 4 includes a rotating protrusion 41 and an annular groove 42. The rotating protrusion 41 is provided at both the upper and lower ends of the outer side of the support ring 3. The annular groove 42 that cooperates with the rotating protrusion 41 is provided at both the upper and lower ends of the inner side of the rotating ring 5. A plurality of balls 43 are embedded at equal intervals on the rotating protrusion 41.

[0016] The rotating protrusion refers to the raised structure set at the upper and lower ends of the outer surface of the support ring. Specifically, it can be made of metal and integrally formed. Through cooperation with the annular groove, the axial positioning and radial rotation of the rotating ring are achieved.

[0017] Among them, the annular groove refers to the annular groove formed on the inner side of the rotating ring body. It can be formed by mechanical processing, and its shape is complementary to the rotating protrusion to achieve a sliding fit between the two.

[0018] Among them, the ball refers to the spherical rolling element embedded in the surface of the rotating protrusion. It can be made of stainless steel and the friction force is evenly distributed during the rotation of the rotating ring by equidistant arrangement.

[0019] Specifically, the engagement of the rotating protrusion and the annular groove forms an axial constraint structure, allowing the rotating ring to rotate only around the axis of the supporting ring. After the ball bearings are embedded in the surface of the rotating protrusion, they generate rolling friction against the inner wall of the annular groove as the rotating ring rotates, thereby reducing rotational resistance. When it is necessary to adjust the alignment of the second and first vents, the on / off relationship between them can be changed by rotating the rotating ring, thus controlling the steam emission rate inside the boiler.

[0020] In existing technologies, rotating parts often get stuck or wear due to friction, while the introduction of balls transforms sliding friction into rolling friction, significantly improving operational smoothness and extending structural life.

[0021] Through the above technical solution, this application solves the problem that fixed sealing structures cannot regulate steam discharge. The pressure dynamic balance is achieved through a rotatable rotating ring, while the ball bearing structure effectively reduces wear on rotating parts, avoids adjustment failure due to excessive friction, and extends the service life of the silicone ring under high temperature and high pressure environments.

[0022] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
