Description

Technical Field

[0001] This utility model relates to the field of kitchen cooking utensils technology, and in particular to a micro-pressure glass cover with a rubber ring. Background Technology

[0002] As a crucial component in the cooking process, the core function of a pot lid is to cover the pot to maintain its internal temperature and pressure, while preventing excessive evaporation of moisture and oil. Among the various pot lid materials, glass lids have become a common choice in modern kitchens due to their transparency, aesthetic appeal, and resistance to absorbing food odors. However, traditional glass pot lids have significant structural flaws: their rigid material makes it difficult to form an effective seal when in contact with the pot, especially in scenarios requiring low-pressure cooking. Insufficient sealing leads to rapid heat loss, not only prolonging cooking time and increasing energy consumption but also affecting the final taste of stewed dishes.

[0003] To address the sealing issue, existing technologies have employed a design involving adding a fixed silicone ring to the edge of the glass pot lid. While this approach temporarily improves the seal by utilizing the elasticity of silicone, it suffers from three fundamental drawbacks: First, the silicone ring is permanently fixed (e.g., glued or pressed in), making it impossible to remove or replace once installed. Second, prolonged exposure to high-temperature steam, grease, and other cooking environments inevitably leads to aging, hardening, cracking, or deformation of the silicone material, resulting in a continuous deterioration of the sealing performance. Third, when the silicone ring fails, users cannot replace it themselves, requiring the replacement of the entire expensive glass pot lid, wasting resources and increasing operating costs. This non-maintainable design severely impacts product lifespan and user experience, contradicting the current emphasis on sustainable consumption. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a micro-pressure glass cover with a silicone ring that allows for easy replacement of the silicone ring to extend its service life.

[0005] This utility model is achieved by the following method: a micro-pressure glass lid with a rubber ring, including a glass lid body, a steel ring is provided on the outer side of the glass lid body, a silicone ring for sealing is provided inside the steel ring, and a replacement part for limiting the silicone ring and facilitating the replacement of the silicone ring is provided on the steel ring.

[0006] Furthermore, the replacement component includes a pressing ring body, on the lower surface of the pressing ring body multiple return springs are evenly spaced, and the upper surface of the steel ring has an annular opening that cooperates with the pressing ring body.

[0007] Furthermore, mounting blocks are provided at both ends of the pressing ring, and the mounting blocks are fixed to the steel ring by bolts.

[0008] The beneficial effects of this utility model are as follows: This utility model achieves quick positioning and replacement of the silicone ring by setting a detachable replacement component structure on the steel ring, which solves the problem of the silicone ring of traditional glass pot lids being unreplaceable and causing the whole thing to be scrapped. It has the advantages of making it easy to replace the silicone ring to extend the service life and reduce the cost of use. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of this utility model.

[0010] Figure 2 This is the front view of the present invention. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] Please see Figure 1 and Figure 2 As shown, this utility model provides an embodiment: a micro-pressure glass lid with a rubber ring, including a glass lid body 1, a steel ring 2 is provided on the outer side of the glass lid body 1, a silicone ring 3 for sealing is provided inside the steel ring 2, and a replacement part 4 is provided on the steel ring 2 for limiting the silicone ring 3 and facilitating the replacement of the silicone ring 3.

[0013] The steel ring refers to the ring-shaped metal structure that surrounds the outside of the glass lid. It can be made of stainless steel or aluminum alloy. Its function is to provide fixed support for the silicone ring and enhance the mechanical strength of the glass edge.

[0014] The silicone ring refers to the annular elastic sealing element embedded inside the steel ring. It can be made of high-temperature resistant silicone material and fills the gap between the glass lid and the pot body by its own deformation to achieve a sealing effect.

[0015] The replacement part refers to the operable structure set on the steel ring. Specifically, it can be a press-type buckle or a spring reset device. It can achieve quick installation and removal of the silicone ring through limiting and releasing actions, avoiding damage to the steel ring or glass body.

[0016] Specifically, the steel ring is mechanically fixed to the outside of the glass lid, while the silicone ring is embedded in a groove inside the steel ring. The replacement part is connected to the steel ring via an elastic element. When the silicone ring needs to be replaced, the replacement part is operated to release the restriction on the silicone ring, allowing the old silicone ring to be removed and replaced with a new one. The replacement part is then re-secured using its reset function. This process does not require disassembling the steel ring or damaging the glass body; it only involves replacing the silicone ring.

[0017] Compared to existing technologies, traditional solutions integrate the silicone ring and glass lid into a single, fixed structure. This solution, however, utilizes a combination of a steel ring and a replacement component, transforming the silicone ring into an independent, replaceable module. This improvement eliminates the need to discard the entire lid when the silicone ring ages; simply replacing the silicone ring restores the seal, significantly reducing maintenance costs.

[0018] Through the above technical solution, this application realizes the function of detachable and replaceable silicone rings, effectively solving the problem of sealing failure caused by silicone aging and extending the service life of glass pot lids. At the same time, the replacement process requires no professional tools or complicated operations, allowing users to complete the maintenance themselves, thus improving the practicality and economy of the product.

[0019] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the replacement component 4 includes a pressing ring 41, a plurality of return springs 42 are evenly arranged on the lower surface of the pressing ring 41, and an annular opening 43 that cooperates with the pressing ring 41 is provided on the upper surface of the steel ring 2.

[0020] The pressing ring refers to the ring-shaped structure surrounding the outer edge of the steel ring. It can be made of metal or hard plastic and its rigid structure enables the positioning and pressing operation of the silicone ring.

[0021] The reset spring is an elastic element that is vertically installed on the lower surface of the pressing ring. It can be implemented using a stainless steel helical spring, which provides an automatic reset function after the pressing ring is pressed down through elastic deformation.

[0022] Among them, the annular opening refers to the continuous groove structure formed by machining the upper surface of the steel ring. Specifically, it can be formed by stamping or cutting processes, and the space for pressing stroke is realized through the gap fit between it and the pressing ring body.

[0023] Specifically, when the silicone ring needs to be replaced, the pressing ring is pressed down, compressing the return spring. At this time, the annular opening provides space for the pressing ring to sink, and the silicone ring can be removed from the steel ring because it is no longer constrained. After the new silicone ring is replaced, the pressing ring automatically returns to its original position under the action of the return spring, thus re-fixing the silicone ring.

[0024] Compared to existing technologies, current silicone ring replacement solutions require destructive removal or rely on adhesive fixation. This solution, however, achieves non-destructive disassembly and assembly through a movable pressing ring and an elastic reset structure, while avoiding the residue problems caused by adhesives.

[0025] Through the above technical solution, this application enables the replacement of silicone rings without tools, solving the problem of difficult replacement of silicone rings caused by the irreversible fixing method in the prior art, and extending the overall service life of the glass pot lid.

[0026] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, mounting blocks 44 are provided at both ends of the pressing ring 41, and the mounting blocks 44 are fixed to the steel ring 2 by bolts.

[0027] The mounting block refers to the fixing component set on both sides of the pressing ring body. Specifically, it can be implemented using a block structure made of metal or high-strength plastic. Its function is to provide a stable connection base for the bolt and ensure reliable fixing between the pressing ring body and the steel ring.

[0028] Bolts are threaded fasteners, which can be made of stainless steel and screwed into the pre-drilled holes of the mounting block and steel ring. Their function is to enable quick installation and removal of the pressing ring through a detachable mechanical connection, avoiding irreversible fixing problems caused by adhesive or pressing.

[0029] Specifically, the pressing ring is connected to the steel ring via mounting blocks at both ends. After aligning the screw holes on the mounting blocks with the corresponding screw holes on the steel ring, bolts are passed through and tightened, firmly fixing the pressing ring to the surface of the steel ring. When the silicone ring needs to be replaced, simply loosen the bolts to detach the pressing ring from the steel ring. The silicone ring can then be directly removed and replaced without damaging the original structure or using special tools. The cooperation between the mounting blocks and bolts ensures the structural stability of the pressing ring under pressure during cooking while also facilitating the replacement of the silicone ring.

[0030] Compared to existing technologies, current silicone rings are typically fixed directly to the edge of glass lids using adhesive or press-fit methods, making them difficult to replace after aging. This solution, however, uses a mechanical connection design with bolts and mounting blocks to change the fixing method between the pressing ring and the steel ring to a detachable one. This avoids the irreversible defects of adhesive bonding and solves the problem of difficult disassembly in traditional press-fit structures, significantly improving the feasibility of silicone ring replacement.

[0031] Through the above technical solution, this application achieves a stable connection and quick disassembly between the pressing ring and the steel ring, allowing the silicone ring to be replaced by the user after aging, avoiding the problem of the entire pot lid being scrapped due to the failure of the silicone ring, reducing the cost of use, and extending the service life of the glass pot lid.

[0032] 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.
