Description

Technical Field

[0001] This utility model relates to the field of pot holders, and more particularly to a magnetic cork pot holder. Background Technology

[0002] Cookware is an indispensable tool in the kitchen. To protect the countertop from the high temperature of the pot's bottom and to improve the stability of the cookware, trivets are widely used as an auxiliary tool. However, traditional trivets have many shortcomings in design and function.

[0003] 1. On the one hand, the magnetic adsorption components of traditional pot holders typically use a simple sandwich structure for installation. This structure is prone to cracking and magnet detachment during long-term use, significantly reducing the pot holder's durability and safety. Magnet detachment not only affects the pot holder's magnetic attraction function but also poses safety hazards.

[0004] 2. Furthermore, traditional pot holders have poor anti-slip properties. Cookware is prone to tipping over due to slippage, which can cause food spills and potentially lead to burns and other safety hazards. Therefore, improving the anti-slip properties of pot holders is crucial for ensuring cooking safety.

[0005] 3. At the same time, the gaps in the seams of traditional pot holders can easily lead to the penetration of oil and water stains, further affecting the cleanliness and lifespan of the pot holders. Summary of the Invention

[0006] To address the aforementioned issues, this utility model provides a magnetic cork pot holder, aiming to solve the problems of traditional pot holders in terms of durability, anti-slip performance, and cleanability through innovative design and technical means, and to provide a safer, more convenient, and more efficient auxiliary product.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a magnetic cork pot holder, comprising a cork substrate body and a magnetic adsorption component, wherein the magnetic adsorption component is completely embedded inside the cork substrate body and forms an integral structure therewith; the cork substrate body is an integral structure formed by hot pressing after mixing powdered cork particles with adhesive, and the magnetic adsorption component is directly embedded between the powder layers during the forming process; a heat insulation and reinforcement structure is provided on the lower surface of the cork substrate body.

[0008] Furthermore, the thickness of the cork substrate body is 10-50mm, and the heat insulation enhancement structure is a convex ridge array disposed on the lower surface. The convex ridge array is composed of multiple concentric ring convex ridges, the spacing between adjacent convex ridges is 5-8mm, and the height of the convex ridges is 2-4mm.

[0009] Furthermore, the magnetic adsorption component includes at least three permanent magnets, which are neodymium iron boron magnets or ferrite magnets, and are distributed in a ring array within the cork substrate.

[0010] Furthermore, the permanent magnet is embedded in the center of the cork substrate body, with a single magnet having a diameter of 5-30mm and a spacing of 8-80mm between adjacent magnets.

[0011] Furthermore, the surface of the magnetic adsorption component is coated with a high-temperature resistant and rust-proof layer, which is an organosilicon resin coating or a ceramic coating, with a coating thickness of 20-50μm and completely covering the outer surface of the magnet.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model's magnetic cork pot holder, through its innovative integrated structural design, achieves a tight bond between the magnetic adsorption component and the cork substrate, completely eliminating the risks of cracking and magnet detachment inherent in traditional sandwich structures, significantly improving product durability. Simultaneously, the thickened substrate design, combined with the heat-insulating reinforcement structure on the lower surface, creates a double thermal barrier, effectively preventing heat transfer from the bottom of the pot to the countertop, protecting the countertop from high-temperature damage. The embedded design of the magnetic component not only ensures efficient magnetic field penetration but also creates a heat-insulating safety distance, preventing magnetic attenuation caused by direct contact with high-temperature areas, achieving a balance between adsorption force and heat insulation performance.

[0014] 2. Furthermore, the anti-slip design of the raised ridge array significantly enhances the stability of the cookware, preventing the risk of slipping and tipping. The integrated sealing structure effectively prevents the penetration of oil and water stains, while the fully embedded design of the magnetic components avoids the attraction of foreign objects to the magnet surface, making daily cleaning simple and convenient.

[0015] 3. This utility model's magnetic cork pot mat is easy to operate and highly adaptable, able to firmly adhere to the bottom of pots of various sizes, achieving a "one-mat-multiple-use" function and improving the product's versatility and stability. In summary, this utility model's magnetic cork pot mat has achieved significant beneficial effects in terms of durability, heat insulation performance, anti-slip performance, ease of cleaning, ease of operation, and adaptability.

[0020] The following are the symbols and their meanings: 1. Cork substrate body; 2. Magnetic adsorption component; 3. Raised edge. Detailed Implementation

[0021] Please see Figure 1-4 As shown, this utility model relates to a magnetic cork pot holder, characterized in that: it is composed of a cork substrate body 1 and a magnetic adsorption component 2, wherein the magnetic adsorption component 2 is completely embedded inside the cork substrate body 1 and forms an integral structure therewith; the cork substrate body 1 is an integral structure formed by hot pressing after mixing powdered cork particles with adhesive; the magnetic adsorption component 2 is directly embedded in the cork substrate body 1 during the forming process; and a heat insulation and reinforcement structure is provided on the lower surface of the cork substrate body 1.

[0022] Through a powder mixing and hot-pressing integrated molding process, the magnetic adsorption component 2 and the cork substrate body 1 form a molecular-level bond, completely eliminating the risks of cracking and magnet detachment in traditional sandwich structures, significantly improving product durability. Furthermore, the substrate body features a thickened design (10-50mm) combined with a lower surface heat-insulating reinforcement structure, creating a double thermal barrier. This structure effectively prevents heat transfer from the bottom of the cookware to the countertop by extending the heat conduction path and forming a static air insulation layer.

[0023] The magnetic components are embedded within the substrate, ensuring efficient magnetic field penetration while maintaining a ≥4mm thermal insulation safety distance. This prevents magnetic attenuation caused by direct contact with high-temperature areas, achieving a balance between adsorption force and thermal insulation performance. The lower surface's thermal insulation enhancement structure employs a 3-array design with raised ridges, improving insulation while significantly enhancing the stability of the cookware by increasing the coefficient of friction on the contact surface, preventing slippage and tipping. The integrated sealing structure eliminates seams found in traditional products, effectively preventing oil and water penetration. The fully embedded magnetic components prevent foreign matter from adhering to the magnet surface, allowing for simple wiping for daily cleaning.

[0024] The cork substrate body 1 has a thickness of 10-50mm, combined with the lower surface ridge array 3 design to form a double heat insulation structure, effectively reducing heat transfer to the countertop. The ridge array 3 consists of multiple concentric ring ridges 3, with an adjacent ridge spacing of 5-8mm and a ridge height of 2-4mm. This structure increases the air layer, reduces heat conduction, and improves the heat insulation effect.

[0025] The design of the substrate thickness and the height of the ridge 3 enhances structural strength while ensuring heat insulation performance. The concentric ring layout of the ridge 3 array ensures more uniform stress distribution, improving product durability. The optimized anti-slip performance is achieved through the three-dimensional structure of the ridge 3 array, increasing friction with the countertop and preventing cookware from sliding during use. The concentric ring layout naturally adapts to the curvature of the cookware's bottom, further enhancing anti-slip performance. The reasonable spacing and height of the ridge 3 prevent continuous oil buildup in the grooves while ensuring effective contact with cleaning tools, facilitating daily cleaning and maintenance. These technical features are compatible with cork hot-pressing molding processes, allowing the substrate and ridge 3 structure to be molded in one step without secondary processing, improving production efficiency.

[0026] Furthermore, the magnetic adsorption component 2 includes at least three permanent magnets, which are neodymium iron boron magnets or ferrite magnets, and are arranged in a ring array within the cork substrate body 1.

[0027] This invention significantly improves the ease of use and adaptability of the magnetic cork pot mat through the optimized layout of the magnetic adsorption component 2. Utilizing a ring-shaped array of neodymium iron boron permanent magnets, a closed magnetic circuit is formed, allowing the pot mat to adhere tightly to the bottom of the cookware. When using the pot, the user can directly place it on the surface of the pot mat, which automatically fixes itself to the bottom due to magnetic attraction. The cookware and pot mat can then be placed together on the table, eliminating the need for pre-positioning the pot mat and simplifying the process.

[0028] Furthermore, the multi-ring magnet layout, with its ring array of varying diameters, allows it to accommodate cookware of various sizes. For example, the outer ring of magnets is suitable for woks with a diameter of 28-32cm, while the inner ring is suitable for soup pots with a diameter of 16-20cm, achieving a "one-piece, multi-purpose" function. This design not only improves the versatility of the pot holder but also ensures stability when using cookware of different sizes.

[0029] Furthermore, the permanent magnet is embedded at a depth of 40%-60% of the thickness of the cork substrate body 1, the diameter of a single magnet is 5-10mm, and the spacing between adjacent magnets is 8-15mm.

[0030] In another embodiment of this application, ferrite magnets with a diameter of 30mm x thickness of 4mm can be selected, and three magnets can be placed with a distance of 75-80mm between each magnet, arranged in a triangle.

[0031] In another specific embodiment, the magnet embedding depth is set to 40%-60% of the substrate thickness. This ensures effective penetration of magnetic lines of force while enhancing the bond strength between the magnet and the cork substrate through deep embedding, effectively preventing the risk of magnet detachment during use. A combination of 5-10mm magnet diameter and 8-15mm spacing creates a uniform magnetic field distribution, eliminating magnetic blind spots common in traditional layouts and improving the uniformity and stability of the magnetic attraction effect. A design with a ≥4mm gap between the lower surface of the magnet and the lower surface of the substrate constructs a physical heat insulation layer, effectively blocking heat from the bottom of the cookware, preventing the magnet from directly contacting high-temperature areas, avoiding magnetic attenuation due to excessive temperature, and extending product lifespan.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
