Abstract
Description
Technical Field
[0001] This utility model relates to the field of non-stick pan technology, specifically a novel micro-dot non-stick pan. Background Technology
[0002] Woks are common cooking utensils, and non-stick pans are particularly popular because they prevent food from sticking to the bottom during cooking, making them easy to use. Current non-stick pans often use coating technology to enhance their non-stick properties, while some products employ physical non-stick methods by introducing a dotted structure to improve physical suspension. However, most dotted designs have the following problems: firstly, the depth and irregular arrangement of the dots make it difficult to clean food residue; secondly, the coating cannot adhere stably to the dots, causing them to easily peel off during use, affecting the lifespan and health and safety. Utility Model Content
[0003] In view of the problems existing in the prior art, this utility model discloses a novel micro-dot non-stick pan. The technical solution adopted is to uniformly process concave dots on the bottom of the pan body through an etching process. The diameter of the concave dots is 0.4 mm and the depth is 0.03-0.04 mm. The distance between two adjacent concave dots is 0.2 mm. The inner and outer surfaces of the pan body are uniformly coated with a coating.
[0004] In a preferred embodiment of this invention, the coating is made of silicon dioxide. The surface of the pot is cleaned ultrasonically and then dried at high temperature. The areas with recessed spots are then cleaned using a laser to ensure the surface is clean and free of oil, dust, etc. A nano-scale silicon dioxide coating is then sprayed onto the pot surface to form a uniform coverage, thus obtaining the coating.
[0005] The beneficial effects of this utility model are as follows: This utility model arranges the concave dots densely, thereby reducing the contact area between the pan surface and the food, achieving physical non-sticking. The concave dots are reasonably sized to prevent dirt from accumulating and make cleaning easy. Together with the coating, they improve the lifespan and non-stick effect of the non-stick pan and ensure safe use. Attached Figure Description

[0009] Example 1
[0010] like Figures 1 to 2As shown, this utility model discloses a novel micro-dot non-stick pan. Dimples 2 are uniformly etched into the bottom of the pan body 1 using an etching process. The diameter of each dimple 2 is 0.4 mm, the depth is 0.03 mm, and the distance between two adjacent dimples 2 is 0.2 mm. A coating 3 is uniformly sprayed onto the inner and outer surfaces of the pan body 1; the coating 3 is made of silicon dioxide. After ultrasonic cleaning and high-temperature drying of the pan body 1, the area where the dimples 2 are distributed is laser-cleaned to ensure the surface is clean and free of oil, dust, etc. A nano-scale silicon dioxide coating is then sprayed onto the surface of the pan body 1, forming a uniform coverage, resulting in coating 3. The dimples 2 create a physical non-stick surface, which, combined with coating 3, effectively enhances the non-stick effect and extends the service life of the pan body 1.

A coating 3 is uniformly sprayed onto the inner and outer surfaces of the pan body 1; the coating 3 is made of silicon dioxide. After ultrasonic cleaning and high-temperature drying of the pan body 1, the area where the dimples 2 are distributed is laser-cleaned to ensure the surface is clean and free of oil, dust, etc. A nano-scale silicon dioxide coating is then sprayed onto the surface of the pan body 1, forming a uniform coverage, resulting in coating 3. The dimples 2 create a physical non-stick surface, which, combined with coating 3, effectively enhances the non-stick effect and extends the service life of the pan body 1.
[0013] Example 3
[0014] like Figures 1 to 2 As shown, this utility model discloses a novel micro-dot non-stick pan. Dimples 2 are uniformly etched into the bottom of the pan body 1 using an etching process.

A coating 3 is uniformly sprayed onto the inner and outer surfaces of the pan body 1; the coating 3 is made of silicon dioxide. After ultrasonic cleaning and high-temperature drying of the pan body 1, the area where the dimples 2 are distributed is laser-cleaned to ensure the surface is clean and free of oil, dust, etc. A nano-scale silicon dioxide coating is then sprayed onto the surface of the pan body 1, forming a uniform coverage, resulting in coating 3. The dimples 2 create a physical non-stick surface, which, combined with coating 3, effectively enhances the non-stick effect and extends the service life of the pan body 1.
