TECHNICAL FIELD
[0001] The utility model relates to the technical field of cooking utensils, and particularly relates to a non-metallic magnetic non-stick liner. BACKGROUND
[0002] In the field of cooking utensils, the design of non-stick liners has always been one of the key technologies for improving cooking experience and efficiency. With the increasing demand of consumers for healthy and convenient cooking, the material and technical implementation scheme of non-stick liners are also constantly updated and iterated. At present, the mainstream 0-coating cooking utensils on the market mainly achieve non-stick effect through two technical schemes: a protective film formed by surface micron-level texture combined with vapor deposition method, and a cooking utensil surface directly treated by bright polishing. However, both of these two technical schemes have certain limitations.
[0003] The first technical scheme, that is, the method of adopting surface micron-level texture and forming a hard protective film on the surface by vapor deposition method, although can achieve non-stick effect to some extent, has disadvantages that cannot be ignored. On the one hand, although the micron-level texture design increases the roughness of the surface, which helps to reduce the contact area between food and the liner, it also brings the problem of difficult cleaning. Once the food is embedded in these tiny textures, cleaning will become extremely tedious, not only affecting the use experience of the cooking utensil, but also possibly breeding bacteria, posing a potential threat to the health of users. On the other hand, as a high-tech process, vapor deposition method has expensive equipment, complex process, and difficult to guarantee the yield, which directly leads to a significant increase in the cost of cooking utensils, which is not conducive to the market promotion and popularization of products.
[0004] The second technical scheme, that is, directly treating the surface of the cooking utensil by bright polishing, although it is low in cost and easy to operate, its non-stick effect is greatly discounted. Since the base material of the cooking utensil itself does not have non-stick property, relying solely on bright polishing cannot effectively improve the non-stick performance of the liner surface. Therefore, this technical scheme often shows poor non-stick effect in actual application, which is difficult to meet the demand of consumers for high-quality cooking utensils. SUMMARY
[0005] In order to overcome at least one of the defects of the prior art described above, the utility model provides a non-metallic magnetic non-stick liner. The problem of poor non-stick property of the liner can be solved.
[0006] The technical scheme adopted by the utility model to solve the problem is:
[0007] A non-metallic magnetic non-stick liner, comprising a liner body, the liner body having a liner inner side and a liner outer side, the thickness direction of the liner body comprising: a first glaze layer; a substrate layer, the substrate layer being made of bamboo charcoal material or ceramic material; wherein the first glaze layer is arranged on one side of the substrate layer facing the liner inner side.
[0008] By adopting the above scheme, the substrate layer is made of environmentally friendly and high-temperature resistant non-metallic materials such as bamboo charcoal material or ceramic material, and the first glaze layer is arranged on one side of the substrate layer facing the liner inner side. Through the special properties and process treatment of glaze, good non-stick effect is achieved.
[0009] Further, a second glaze layer is arranged on one side of the substrate layer facing the liner outer side.
[0010] By adopting the above scheme, the second glaze layer can enhance the hardness and wear resistance of the liner outer side, protect the substrate layer from physical damage such as scratching and wear during daily use. It can also enhance the magnetic properties of the liner as a whole to some extent, not only improving the practicality and aesthetics of the product, but also increasing the added value and differentiation advantage of the product.
[0011] Further, the liner body comprises, from top to bottom: a liner mouth section, the upper edge of the liner mouth being outwardly folded to form a flange; a liner neck section, the upper edge of the liner neck section being connected to the lower edge of the liner mouth section; a side body section, the upper edge of the side body section being connected to the lower edge of the liner neck section; and a liner bottom section, the upper edge of the liner bottom section being connected to the lower edge of the side body section.
[0012] By adopting the above scheme, the flange only increases the strength and stability of the liner mouth, and also facilitates the user to hold and carry the liner, and also helps to prevent food or liquid from spilling during cooking; the liner neck section helps to reduce heat loss during cooking, and also prevents food from spilling from the liner mouth during stirring or pouring.
[0013] Further, the outer diameter of the liner mouth section is greater than the outer diameter of the side body section, and the outer diameter of the side body section is greater than the outer diameter of the liner neck section.
[0014] By adopting the above scheme, the outer diameter of the liner mouth section is the largest, so that the user can easily find the point of application of force when holding and carrying the liner, improving the convenience and safety of operation.
[0015] Further, a first transition surface is arranged between the liner mouth section and the liner neck section, and the first transition surface is a curved surface.
[0016] By adopting the above scheme, the stress concentration of the inner container when subjected to external force can be more effectively dispersed, thereby enhancing the overall structural strength of the inner container and prolonging the service life.
[0017] Further, a second transition surface is arranged between the neck section and the side body section, and the second transition surface is a curved surface.
[0018] By adopting the above scheme, the transition between the neck section and the side body section is smoother and more natural, effectively reducing the stress concentration phenomenon caused by shape mutation, thereby enhancing the structural stability and durability of the inner container.
[0019] Further, a third transition surface is arranged between the side body section and the bottom section, and the third transition surface is a curved surface.
[0020] By adopting the above scheme, it is helpful for heat to be more uniformly transmitted between the side body section and the bottom section, avoiding the accumulation or loss of heat in the transition area, improving the cooking efficiency and the uniform heating degree of the food materials; the curved surface design reduces the cleaning dead angle of the inner container surface, making it easier for the user to remove stains and residues when cleaning the inner container.
[0021] Further, at least one side of the turned edge is provided with a flange.
[0022] By adopting the above scheme, the design of the flange increases the strength and rigidity of the turned edge, making the inner container mouth more stable. This helps to prevent deformation or damage of the inner container due to accidental collision during handling or use. In some cases, the flange can form a tighter fit with the inner container cover or other sealing components, thereby enhancing the sealing performance of the inner container. This helps to prevent steam, heat and aroma from escaping during cooking, maintaining the closed nature of the cooking environment and the consistency of the cooking effect.
[0023] Further, the cross section of the flange is hemispherical or ellipsoidal.
[0024] By adopting the above scheme, the design of the hemispherical or ellipsoidal flange gives the inner container a more smooth and harmonious appearance, improving the overall aesthetic of the product. The cleaning dead angle of the inner container surface is reduced, making it easier for the user to remove stains and residues when cleaning the inner container.
[0025] Further, the diameter of the side body section gradually increases from top to bottom.
[0026] By adopting the above scheme, it is helpful for heat to be more uniformly distributed during cooking. This helps to ensure that the food materials can be uniformly heated during cooking, improving the cooking efficiency and the taste of the food materials.
[0027] In summary, the non-metallic magnetically conductive non-stick inner container has the following technical effects:
[0028] 1. By arranging the first glaze layer on the side of the substrate layer facing the inner side of the liner, the special properties and process treatment of the glaze are used to effectively reduce the direct contact between food and the surface of the liner, thereby achieving good non-stick effect. This solves the problem of poor non-stickness of the traditional cooking utensil liner, making the cooking process smoother, and the food is not easy to stick to the pot, and the cleaning is more convenient;
[0029] 2. The substrate layer is made of bamboo charcoal material or ceramic material, etc. Non-metallic materials such as environmental protection and high temperature resistance, which are non-toxic and harmless to human health. Compared with traditional non-stick coating materials, the non-stick liner of the utility model is safer and healthier, which meets the pursuit of modern consumers for healthy life;
[0030] 3. The bamboo charcoal material and the ceramic material both have good high temperature resistance and can withstand temperature changes during high temperature cooking process without deformation or damage. This makes the non-stick liner of the utility model more stable and reliable during cooking process, prolonging the service life;
[0031] 4. Although the substrate layer is made of non-metallic material, it still maintains good magnetic conductivity through special design and treatment. This makes the liner suitable for electromagnetic heating equipment such as induction cooker, improving the flexibility and convenience of cooking. BRIEF DESCRIPTION OF DRAWINGS
