Description

Technical Field

[0001] The invention relates to the technical field of non-stick pans, and in particular to a non-stick pan with micropores on its inner wall. Background Art

[0002] A pan is a common cooking utensil. In order to prevent food from sticking to the inner wall of the pan during cooking such as frying and frying, non-stick pans came into being. At present, non-stick pans on the market generally use coatings to prevent sticking, but the coatings are easy to fall off after long-term use. When the coatings fall off, the pan will lose its non-stick properties, and the fallen coatings mixed with food will cause harm to human health. Therefore, the present application provides a non-stick pan with micropores on the inner wall, and the pan has non-stick properties by setting micropores on the inner wall of the pan. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a non-stick pan with micropores on the inner wall in view of the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a non-stick pan with micropores on the inner wall, comprising a pan body, the inner wall of the pan body is provided with a plurality of micropores, the pore diameter of the micropores is 0.05-0.07 mm, the pore depth of the micropores is 0.02-0.03 mm, and the distance between adjacent micropores is 0.32 mm.

[0005] To further optimize the technical solution, the microholes are engraved by femtosecond laser.

[0006] To further optimize the technical solution, the pot body is made of titanium.

[0007] To further optimize the technical solution, the pot body is made of iron, cast iron, composite steel or stainless steel.

[0008] To further optimize the technical solution, two connecting columns are provided on the upper part of the outer wall of the pot body, and the connecting columns are provided with external threaded parts.

[0009] To further optimize the technical solution, the connecting column is welded to the pot body.

[0010] To further optimize the technical solution, the thickness of the bottom of the pot body is greater than the thickness of its side wall.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The inner wall of the pot body is densely covered with micropores, so that it has a non-stick property, so that there will be no problems caused by the coating falling off; 2. Two connecting columns are arranged on the upper part of the outer wall of the pot body, and the connecting columns are provided with external threaded parts, so there is no need to open holes on the pot body to connect the handle; 3. The thickness of the bottom of the pot body is greater than the thickness of its side wall, so it is not easy to stick to the pot, and the weight of the pot is reduced.

[0015] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0016] Specific implementation method: Combination Figure 1-2 As shown, a non-stick pan with micropores on the inner wall comprises a pan body 1, wherein the inner wall of the pan body 1 is provided with a plurality of micropores, wherein the aperture (i.e., diameter) of the micropores is 0.05-0.07 mm, the depth of the micropores is 0.02-0.03 mm, and the distance between adjacent micropores is 0.32 mm. When cooking, edible oil needs to be first added to the pan body 1, and then the pan body 1 is tilted and shaken in multiple directions so that the edible oil is coated on the inner wall of the pan body 1, and the edible oil will enter the micropores. During the cooking process, the food is difficult to enter the micropores due to the small aperture, so that the edible oil will be reliably stored in the micropores (the edible oil can separate the food from the pan body 1), and since the micropores are densely distributed on the inner wall of the pan body 1 with the above parameters, the pan body 1 has a non-stick property. Since the non-stick pan of the present application does not have a coating, there will be no problems caused by the coating falling off.

[0017] Specifically, the micro-holes are engraved by femtosecond laser, and the femtosecond laser engraving equipment is controlled by a program, which can well control the pore diameter, pore depth and pore distance of the micro-holes.

[0018] Furthermore, the material of the pot body 1 is titanium. Although titanium itself is not hydrophobic, due to the above-mentioned parameters of the micropores, the inner wall of the pot body 1 has hydrophobic properties. Therefore, when the inner wall of the pot body 1 is cleaned, sewage is not easy to remain on the inner wall of the pot body 1, thereby making it easier to rinse the pot body 1 clean.

[0019] Furthermore, the material of the pot body 1 is iron (low carbon content, good deformability, and can be made into the pot body 1 by spinning or stamping an iron plate), cast iron (cast iron has a high carbon content, and the pot body 1 is obtained by casting), composite steel (such as stainless steel-aluminum-stainless steel, three-layer brazing composite) or stainless steel, which has a low cost. In this case, the inner wall of the pot body 1 does not have hydrophobic properties, but still has good non-stick properties.

[0020] Furthermore, two connecting columns 2 are provided on the upper part of the outer wall of the pot body 1, and the connecting columns 2 are provided with external threaded parts. Two through holes can be provided at the front end of the handle. The two connecting columns 2 pass through the two through holes respectively and are connected with nuts, so that the handle can be fixed on the pot body 1. In this way, there is no need to open through holes on the pot body 1 and then connect the handle with rivets (the presence of rivets makes it difficult to clean the inner wall of the pot body where they are located).

[0021] Specifically, the connecting column 2 is welded to the pot body 1. The connecting column 2 is first processed and then welded to the outer wall of the pot body 1, so that there is no need to open a hole in the pot body 1.

[0022] Further, combined with Figure 2 As shown, the thickness of the bottom of the pot body 1 is greater than the thickness of its side wall. Since the bottom of the pot body 1 is thicker, it is not easy to get stuck, and the side wall is thinner, which reduces the weight of the pot and saves materials.

[0023] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
