Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a wide-edged drain cover with a groove. Background Technology

[0002] Glass pot lids are popular with consumers because of their aesthetic appeal and ease of observation of the food cooking inside. Currently, glass pot lids on the market are typically reinforced with metal edging and have a silicone sealing ring on the inside of the edging to ensure a tight seal with the pot, preventing excessive steam leakage during cooking and maintaining a slightly pressurized environment inside the pot.

[0003] However, existing glass pot lids of this type still have some obvious drawbacks in practical use:

[0004] Sealing performance is prone to degradation: Traditional silicone sealing rings are usually fixed to the metal edging using adhesive or clips. After prolonged exposure to high temperatures, moisture corrosion, and frequent cleaning, the silicone rings are prone to aging, deformation, or loosening from their fixing points, leading to a decline in sealing performance and resulting in water and air leaks. This not only affects cooking results but may also cause energy waste and safety risks.

[0005] Poor adaptability: Due to manufacturing tolerances or deformation of the pot body caused by long-term use, there may be slight uneven gaps between the edge of the pot body and the lid. Traditional fixed sealing rings are difficult to compensate for these gap variations and cannot ensure uniform compression and sealing across the entire circumference of the lid, easily leading to localized leaks.

[0006] Poor condensation management: During cooking, a large amount of condensation will form on the inner wall of the pot lid. Some designs use grooves on the edge of the lid to guide the water flow, but if the seal is not tight or the drainage structure is not designed properly, condensation may still leak from the joint between the lid and the pot body, making the stovetop dirty. In addition, the connection structure between the curved steel ring and the glass lid body in existing technology has insufficient stability, and it is prone to loosening during frequent opening and closing, affecting the sealing effect and service life. Summary of the Invention

[0007] In view of this, the purpose of this utility model is to provide a wide-edge grooved drain cover that can achieve stable sealing performance and effectively prevent condensate leakage.

[0008] This utility model is achieved by the following method: a wide-edged, grooved, leak-proof lid, comprising a glass lid body, and a first arc-shaped steel ring and a second arc-shaped steel ring. The first arc-shaped steel ring and the second arc-shaped steel ring are fitted onto the edge of the glass lid body. A limiting member is provided at the connection between the first arc-shaped steel ring and the second arc-shaped steel ring. The limiting member includes a connecting plate. A fixing block is provided on the connecting plate. A screw is spirally embedded on the fixing block. A movable block is provided at the end of the screw. The movable block is connected to a leak-proof block via a connecting member. The leak-proof block is located below the connecting plate. An elastic rubber block is provided on the inner side of the leak-proof block. A rubber pressure block for contacting the edge of the pot body is provided on the inner side of the elastic rubber block.

[0009] Furthermore, the connector includes a connecting rod, and both ends of the connecting plate are provided with strip-shaped guide openings. The moving block and the leak-proof block are connected by the connecting rod, which passes through the strip-shaped guide openings.

[0010] Furthermore, the upper surface of the glass pot lid body is provided with an exhaust hole, and the first arc-shaped steel ring and the second arc-shaped steel ring extend inward with an arc-shaped limiting groove, and a sealing ring is provided in the arc-shaped limiting groove.

[0011] The beneficial effects of this utility model are as follows: the adjustable screw in the limiting component drives the leak-proof block to press the edge of the pot body, and the elastic rubber block adaptively compensates for the gap change. At the same time, the arc-shaped steel ring and the sealing ring work together to effectively solve the problems of easy aging and loosening and poor adaptability of traditional sealing structures. It has the advantages of stable sealing performance, strong adaptability, easy adjustment and maintenance, and effective prevention of condensate leakage. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please see Figures 1 to 4As shown, this utility model provides an embodiment: a wide-edged, grooved, leak-proof lid, including a glass lid body 1, and a first arc-shaped steel ring 2 and a second arc-shaped steel ring 3. The first arc-shaped steel ring 2 and the second arc-shaped steel ring 3 are fitted onto the edge of the glass lid body 1. A limiting member 4 is provided at the connection between the first arc-shaped steel ring 2 and the second arc-shaped steel ring 3. The limiting member 4 includes a connecting plate 41. A fixing block 42 is provided on the connecting plate 41. A screw 43 is spirally embedded on the fixing block 42. A moving block 44 is provided at the end of the screw 43. A leak-proof block 46 is connected to the moving block 44 via a connecting member 5. The leak-proof block 46 is located below the connecting plate 41. An elastic rubber block 47 is provided on the inner side of the leak-proof block 46. A rubber pressure block 48 for contacting the edge of the pot body is provided on the inner side of the elastic rubber block 47.

[0018] Among them, the first arc-shaped steel ring and the second arc-shaped steel ring refer to the metal reinforcing components distributed along the circumference of the pot lid. Specifically, they can be made of stainless steel stamping parts to enhance the structural strength of the pot lid edge.

[0019] The limiting component refers to the positioning assembly that connects the two steel rings. Specifically, it can be made of a stamped steel plate with a strip-shaped guide opening, which is used to constrain the movement trajectory of the leak-proof block.

[0020] A screw is an adjusting component with threads, which can be made of stainless steel hexagonal bolts. It converts rotational motion into linear displacement of a moving block.

[0021] Leak-proof blocks refer to sealing components with flow guide grooves. They can be injection molded from polytetrafluoroethylene (PTFE) material, and the elastic rubber blocks on their inner side can deform to compensate for the gaps in the pot body.

[0022] Specifically, when the screw is rotated, the movable block connected to the end is displaced along the strip guide opening, which drives the leak-proof block towards the edge of the pot body via the connecting rod. The elastic rubber block undergoes radial deformation under pressure, causing the rubber block to fit tightly against the edge of the pot body. This structure allows for individual adjustment of gap differences in different areas. For example, when a dent appears in a certain part of the pot body, the screw at the corresponding position can be adjusted individually to locally press down the leak-proof block to compensate for the gap.

[0023] Compared to existing technologies, traditional sealing rings, which use a fixed, integral method, cannot provide localized pressure adjustment. This solution, however, dynamically adapts to uneven gaps caused by pot deformation by independently controlling the positions of multiple leak-proof blocks. In existing technologies, replacing the sealing ring requires disassembling the entire steel ring, while this solution only requires loosening the screws to remove the leak-proof blocks for maintenance.

[0024] Through the above technical solution, this application achieves independent adjustment of sealing pressure in different sections, effectively compensating for uneven gaps caused by local deformation of the pot body. The detachable leak-proof block structure simplifies the replacement process of the sealing components, and the deformation characteristics of the elastic rubber block reduce the requirements for manufacturing precision while maintaining the sealing effect.

[0025] Please continue reading. Figures 1 to 3 As shown, in one embodiment of the present invention, the connector 5 includes a connecting rod 51, and both ends of the connecting plate 41 are provided with strip-shaped guide openings 52. The moving block 44 and the leak-proof block 56 are connected by the connecting rod 51, and the connecting rod 51 passes through the strip-shaped guide openings 52.

[0026] The connecting rod is a rigid rod-shaped component used to transmit the force between the moving block and the leak-proof block. It can be made of stainless steel cylindrical rod and is detachably connected to the moving block and the leak-proof block by threads at both ends of the rod. The strip guide port is a straight through groove opened on both sides of the connecting plate. It can be formed by laser cutting and extends parallel to the edge of the connecting plate in the length direction to limit the movement trajectory of the connecting rod.

[0027] Specifically, after passing through the strip-shaped guide opening, the connecting rod is fixedly connected at both ends to the moving block and the leak-proof block, respectively. When the screw drives the moving block to rotate and shift, the connecting rod moves horizontally along the extension direction of the strip-shaped guide opening, thereby driving the leak-proof block to move synchronously closer to or away from the edge of the pot. The strip-shaped guide opening constrains the movement path of the connecting rod, ensuring that the leak-proof block always moves in a predetermined direction, avoiding uneven distribution of sealing pressure due to force deviation.

[0028] Compared to existing technologies, traditional sealing structures use fixed connecting rods, which cannot compensate for positional changes based on pot deformation or manufacturing tolerances. This solution, through the sliding engagement of a strip-shaped guide opening and the connecting rod, enables the leak-proof block to have horizontal adjustment capabilities. It automatically adapts to localized gap changes at the pot's edge when the lid is closed, ensuring a uniform distribution of sealing pressure.

[0029] Through the above technical solution, this application achieves dynamic adjustment of the contact pressure between the leak-proof block and the edge of the pot body, solving the problem of local sealing failure caused by pot body deformation or installation errors. The matching structure of the connecting rod and the strip guide port enables the sealing component to be self-adaptive, while simplifying the disassembly process and making it convenient for users to clean or replace the leak-proof block.

[0030] Please continue reading. Figures 1 to 4 As shown, in one embodiment of the present invention, an exhaust hole 11 is provided on the upper surface of the glass pot lid body 1, and the first arc-shaped steel ring 2 and the second arc-shaped steel ring 3 extend inwardly to form an arc-shaped limiting groove 12, and a sealing ring 13 is provided in the arc-shaped limiting groove 12.

[0031] The vent is a through-hole that penetrates the upper surface of the glass lid. Specifically, it can be implemented using circular holes with a diameter of 3 to 5 millimeters, arranged in a ring array along the center of the lid. This structure is used to balance the pressure inside the pot and guide the condensate backflow.

[0032] The arc-shaped limiting groove refers to the groove formed by the inward extension of the inner walls of the first and second arc-shaped steel rings. It can be manufactured using a stamping process, with a groove depth of 2 to 4 millimeters. This structure is used to fix the sealing ring and limit its radial displacement.

[0033] The sealing ring is an elastic sealing component embedded in an arc-shaped limiting groove. It can be made of silicone or fluororubber and has a rectangular or trapezoidal cross-sectional shape. This structure is used to fill the gap between the lid and the pot body to achieve a seal.

[0034] Specifically, vent holes are made on the upper surface of the glass lid, allowing excess steam generated during cooking to escape through the holes and preventing excessive pressure inside the pot from causing seal failure. The first and second arc-shaped steel rings form an arc-shaped limiting groove by inward indentation, precisely confining the sealing ring within the groove and preventing displacement due to thermal expansion or mechanical vibration. When the lid is closed, the sealing ring is deformed under pressure and fits tightly against the edge of the pot, compensating for localized gap differences caused by manufacturing tolerances or pot deformation.

[0035] Compared to existing technologies, traditional glass pot lids rely on simple snap-fit ​​or adhesive fixing of the sealing ring, which is prone to detachment or deformation under high temperatures. This solution, however, uses an arc-shaped limiting groove to provide three-dimensional constraint on the sealing ring, significantly improving its fixing reliability. Furthermore, existing technologies lack an active venting structure, allowing condensate to leak along the lid's edge. This solution guides steam out in a directional manner through vent holes, while simultaneously promoting the return of condensate into the pot.

[0036] Through the above technical solution, this application solves the water leakage problem caused by the loose sealing ring of traditional glass pot lids, improves the sealing failure caused by pressure fluctuations inside the pot, and reduces the risk of condensate overflow through the synergistic effect of the vent and the sealing ring.

[0037] 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.
