Abstract
Description
Technical Field
[0001] This utility model belongs to the field of kitchenware manufacturing technology, specifically relating to an anti-friction non-stick pan. Background Technology
[0002] Non-stick pans are cookware that prevent food from sticking during cooking by adding a special coating to the surface of the pan. The core principle is to use the physical properties of the non-stick coating (such as Teflon or ceramic) to reduce the contact area and adhesion between food and the bottom of the pan, making the pan walls easier to clean and keep clean. However, during daily use, the non-stick coating is prone to damage, peeling, or sticking due to physical scratches, chemical corrosion, and other reasons.
[0003] Current non-stick pans often focus on the main cooking areas on the bottom and sides of the pan because these areas are in direct contact with the tools and are used frequently. The edge of the pan is often neglected, but its environment is more complex, with both physical factors (such as collisions when stirring) and chemical corrosion (accumulation of food residue). The combination of these factors is very likely to cause the coating edge to peel off prematurely and fail. Utility Model Content
[0004] The purpose of this invention is to provide an anti-friction non-stick pan. By setting a truncated cone-shaped inclined wall and a first coating at the pan opening, a gradient protection is formed, which effectively decomposes the vertical pressure of the spatula on the coating surface and guides the flow of soup and oil to avoid local immersion and corrosion. The outward folded lip can also protect the edge of the pan body and prevent the coating edge from falling off due to bumps and friction.
[0005] The specific technical solution adopted by this utility model is as follows: A non-stick, abrasion-resistant pan includes a pan body and an inclined wall. The inner wall of the inclined wall is provided with a first coating, and the inclined wall is inclined outward relative to the axial direction of the pan body.
[0006] The inclined wall has vertically extending vertical walls and outwardly folded lips integrally formed on both sides of its circumferential direction.
[0007] The vertical wall is integrally formed and connected to the periphery of the arc-shaped wall of the pot body.
[0008] The pot body and the inner wall of the vertical wall are provided with a second coating, and the thickness of the first coating is greater than that of the second coating.
[0009] The inclined wall has an inclination angle of 35° to 55° and a radial thickness of 3 to 5 mm.
[0010] The inclined wall is an alloy particle layer, which is anchored to the first coating through a supersonic cold spraying process.
[0011] The first coating is made of titanium ceramic coating.
[0012] The lip is made of uncoated stainless steel, and its free end is folded outward to form a folded edge structure with a folding angle of 5° to 10°.
[0013] The technical effects achieved by this utility model are as follows: by setting a truncated cone-shaped inclined wall and a first coating at the pot opening, a gradient protection is formed, which effectively decomposes the vertical pressure of the spatula on the coating surface and guides the flow of soup and oil, avoiding local immersion corrosion. The outward folded lip can also protect the edge of the pot body, preventing the coating edge from falling off due to bumps and friction. Attached Figure Description

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0017] like Figures 1-3 As shown, an anti-friction non-stick pan includes a pan body 1 and an inclined wall 102. The inclined wall 102 has vertically extending vertical walls 101 and outwardly folded lips 103 integrally formed on both sides of its circumferential direction. The vertical walls 101 are integrally formed and connected to the arc-shaped periphery of the pan body 1. The inner wall of the inclined wall 102 is provided with a first coating 104, and the inner walls of the pan body 1 and the vertical wall 101 are provided with a second coating 105. The thickness of the first coating 104 is greater than that of the second coating 105. The inclined wall 102 is inclined outward relative to the axial direction of the pan body 1. The inclination angle of the inclined wall 102 is 35° to 55°, and its radial thickness is 3 to 5 mm. The inclined wall 102 is an alloy particle layer and is anchored and bonded to the first coating 104 by a supersonic cold spraying process. The first coating 104 is made of titanium ceramic coating. The lip 103 is made of stainless steel without coating, and its free end is folded outward to form a folded edge structure with a folding angle of 5° to 10°.
[0018] According to the above structure, the vertical wall 101 is located above the original pot opening of the pot body 1, and is coated with the second coating 105 as a basic anti-splash layer, effectively absorbing splashed oil and soup. The top of the wall extends into a 35° to 55° inclined wall 102, forming a smooth inclined slope. Tungsten carbide / zirconia particles are pre-placed using supersonic cold spray technology to form a hard base, and then covered with a thickened first coating 104. The inclined surface converts the vertical pressure into a parallel component force to reduce wear, while guiding the soup and oil stains to flow along the inclined surface to the bottom of the pot. The outer lip 103 adopts an uncoated stainless steel micro-raised design, which prioritizes the bearing of tool friction and transfers the impact that originally acted on the edge of the coating to the more robust lip 103. The overall structure achieves all-round protection of the coating through material composite, angle optimization and functional zoning.
[0019] The working principle of this utility model is as follows: the vertical wall 101 is located above the original pot opening of the pot body 1, maintaining the original cooking space depth, and both it and the pot body 1 are covered with a second coating 105, which serves as a basic anti-splashing layer to absorb most of the splashed oil and soup. Furthermore, the inclined wall 102 extends at the top of the vertical wall 101, forming a smooth inclined slope. Submicron-sized tungsten carbide / zirconia ceramic particles can be directly sprayed onto its surface to form a hard base through a supersonic cold spraying process. Then, a first coating layer 104 is thickly applied. When the spatula touches the edge of the pan, the 35° to 55° inclined surface will decompose the vertically downward pressure into a component force parallel to the inclined surface. Compared with an ordinary flat surface, this inclined surface can significantly reduce the amount of wear. Furthermore, the double-layer structure of the first coating 104 and the inclined wall 102 particles also makes the most vulnerable corner the most resilient part. All the splashed vegetable juice and oil will flow down the inclined surface and into the bottom of the pot, and will not remain on the surface to corrode the coating. Furthermore, the outermost edge 103 is slightly raised outwards and is made of uncoated stainless steel, so it is not afraid of scratches. For example, when wiping with a spatula handle or a wet cloth, the first thing that comes into contact with is this metal edge, which can transfer the impact / friction that originally occurred at the edge of the coating to the more durable edge 103.
[0020] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
