Description

TECHNICAL FIELD

[0001] The utility model relates to kitchen utensil technical field, concretely relates to a kind of cookers. BACKGROUND

[0002] The existing cookers can form relevant identification on them, such as brand, function and size identification information, so as to provide more convenience for users in the use process. However, these identification information is often quickly worn off in the process of using the cookers, resulting in that the relevant identification function cannot be displayed to the user persistently.

[0003] Based on the above situation, it is necessary to provide a cooker with persistent identification function. CONTENT OF UTILITY MODEL

[0004] Therefore, the purpose of the utility model is to provide a cooker to solve the problem that the relevant identification function of the existing cookers cannot be displayed to the user persistently.

[0005] According to the utility model, a cooker is provided, wherein the cooker comprises a cooker base body, a laser printing structure and a protective layer, wherein the laser printing structure is arranged on the cooker base body; and the transparent surface layer is arranged on the cooker base body and can cover the laser printing structure.

[0006] According to the cooker provided by the embodiment of the present application, the laser printing structure can display identification information (such as brand, function and size identification information, and the identification information can be in the form of pattern, two-dimensional code, symbol or text) related to the cooker. In this way, the cooker has the function of displaying relevant identification information. The transparent surface layer serves as a protective layer, is arranged on the cooker base body and can cover the laser printing structure. In this way, the laser printing structure can be prevented from being directly contacted with the external environment, so that it can be protected from wear, scratching and chemical corrosion, and the relevant identification information can be ensured to have persistent clarity and color brightness, so as to provide a relatively persistent display function for the user. In addition, the transparent surface layer can further enhance the three-dimensionality and visual effect of the laser printing structure due to its transparency, and improve the overall aesthetic appearance of the cooker.

[0007] In some embodiments, the laser printing structure comprises laser printing grooves and / or a plurality of protrusions formed by laser with predetermined patterns, symbols and / or texts as references.

[0008] In the embodiments, the laser printing structure is formed by taking the laser printing groove and / or the plurality of protrusions in the predetermined pattern, symbol and / or character as a reference, which can meet the requirement of the cookware for the identification setting. In addition, the laser printing structure is in the form of the laser printing groove, and the transparent surface layer covering the outside can fill the laser printing groove, so that the stereoscopic sense and visual effect of the laser printing structure are more obvious. In addition, the setting can also increase the adhesion of the transparent surface layer, and the transparent surface layer can also ensure the easy cleaning of the cookware, avoiding dirt and the like from being stuck in the laser printing groove.

[0009] In some embodiments, the thickness of the transparent surface layer is d1, wherein 5 microns≤d1≤10 microns. Such thickness can provide durable protection for the laser printing structure and improve the durability of the display function of the laser printing structure.

[0010] In some embodiments, the transparent surface layer has a temperature resistance of 300-400°C. In this way, the protective effect of the transparent surface layer of the cookware can be ensured not to be easily invalidated due to excessive temperature. In addition, when the transparent surface layer also serves as the non-stick layer of the cookware, the non-stick effect of the cookware can be ensured by avoiding invalidation of the non-stick layer of the cookware due to high temperature.

[0011] In some embodiments, the laser printing structure is arranged on the outer surface and / or the inner surface of the cookware base. When the laser printing structure is arranged on the outer surface of the cookware base, it can be used to display information such as the brand, function and size of the product. When the laser printing structure is arranged on the inner surface of the cookware base, it can be used to display the capacity scale, warning signs and the like.

[0012] In some embodiments, a primer coating is arranged on the cookware base, the laser printing structure is formed on the primer coating, and the transparent surface layer covers the outside of the primer coating.

[0013] In the embodiments, the primer coating is used as the substrate for laser printing, which can make the laser printing structure formed more clearly under the contrast of the subsequent transparent surface layer, thereby improving the stereoscopic sense and visual effect of the laser printing structure. In addition, it can also avoid affecting the strength of the cookware base. In addition, the primer coating can provide good adhesion, which can ensure that the laser printing structure is firmly attached to the cookware base by means of the primer coating, and can ensure the bonding force between the transparent surface layer, thereby avoiding the problem of peeling off of the layers of the cookware due to poor bonding force.

[0014] In some embodiments, the primer layer has a thickness d2, where 20 microns ≤ d2 ≤ 30 microns. If the thickness of the primer layer is too thin, a uniform film layer can not be formed, in which case a laser printing structure of sufficient thickness can not be provided, resulting in unclear or incomplete display. If the thickness of the primer layer is too thick, the bonding force between the primer layer and the cookware base can be affected due to the excessive thickness, thereby affecting the bonding performance between the layers of the cookware. In addition, an excessively thick coating layer can increase production costs and processing difficulty.

[0015] In some embodiments, the transparent surface layer and the primer layer are formed of silicone paint or fluorine paint.

[0016] In these embodiments, the primer layer is formed of silicone paint or fluorine paint, which can be burned by laser to form a laser printing structure, facilitating manufacturing. In addition, the primer layer can be tightly bonded to the cookware base, ensuring the overall bonding force of the cookware. The transparent surface layer formed of silicone paint or fluorine paint can improve the bonding force with the primer layer while ensuring the display function of the laser printing structure.

[0017] In some embodiments, the cookware further comprises a magnetic conductive layer disposed between the cookware base and the primer layer.

[0018] In these embodiments, by providing a magnetic conductive layer, the type of heat source that the cookware can be applied to can be increased, for example, a cookware with a magnetic conductive layer can not only be applied to open flames, but also be used on an induction cooker.

[0019] In some embodiments, the magnetic conductive layer comprises an iron, cobalt or nickel layer.

[0020] In these embodiments, the materials forming the magnetic conductive layer are diversified, so that a suitable magnetic conductive layer can be selected based on cost, performance requirements, application scenarios, to ensure good performance and user satisfaction of the cookware when used on electromagnetic induction heating equipment such as induction cookers.

[0021] In some embodiments, the cookware further comprises a protective layer covering the outer side of the magnetic conductive layer.

[0022] In these embodiments, the protective layer is provided on the outer side of the magnetic conductive layer, which can block the contact of corrosive media with the magnetic conductive layer, ensuring the service life of the magnetic conductive layer.

[0023] In some embodiments, the cookware base is an aluminum base, a titanium base or an iron base, the type of the base of the cookware is diversified, and various performance-tended cookware can be manufactured based on needs, for example, when lightweight is the main purpose, the aluminum base can be selected, when corrosion resistance is the main purpose, the titanium base can be selected, and when the human body beneficial elements are the main purpose, the iron base can be selected.

[0024] In some embodiments, the outer edge of the bottom wall of the cookware base is provided with a support boss protruding downward relative to the bottom wall, and the laser printing structure is arranged on the inner side of the support boss, wherein the laser printing structure can ensure the display function of the cookware, and the support boss can ensure that the electromagnetic heating function of the cookware is not easily lost in subsequent use.

[0025] In these embodiments, the specific arrangement area of the laser printing structure on the cookware base is defined, thus, the manufacturing can be facilitated, and the aesthetic appearance of the cookware can be ensured to meet the individualized needs of more user groups.

[0041] In addition, in the description of the examples, when it is considered that a detailed description of the related components or functions known will cause a vague interpretation of the present disclosure, such detailed description will be omitted.

[0042] The embodiments of the present disclosure will be described below in conjunction with Figures 1 to 3 to introduce the cookware provided by the embodiments of the present disclosure.

[0043] According to the embodiments of the present disclosure, a cookware is provided, wherein, as Figures 1 to 3 shown, the cookware includes a cookware base body 10, a laser printing structure 20 and a transparent surface layer 30, the laser printing structure 20 is arranged on the cookware base body 10 and is used to display the identification information related to the cookware, and the transparent surface layer 30 is arranged on the cookware base body 10 and can cover the laser printing structure 20.

[0044] According to the cooking utensil provided in the embodiments of the present application, the laser printing structure 20 can display the identification information (for example, brand, function, size and other identification information, which can be in the form of a pattern, a two-dimensional code, a symbol or a character) related to the cooking utensil. In this way, the cooking utensil has the function of displaying the related identification information. The transparent surface layer 30, as a protective layer, is arranged on the cooking utensil base body 10 and can cover the laser printing structure 20. In this way, the laser printing structure can be prevented from directly contacting the external environment, so that it can be protected from wear, scratches and chemical corrosion, and the related identification information can be ensured to have persistent clarity and color brightness, thereby providing the user with a more persistent display function. In addition, the transparent surface layer 30 can further enhance the three-dimensionality and visual effect of the laser printing structure 20 due to its transparency, thereby improving the overall aesthetic appearance of the cooking utensil.

[0045] According to the present application, the laser printing structure 20 can be formed with reference to the related identification information. For example, in the case where the identification is A, the laser printing structure 20 can be formed by the laser printing device based on A.

[0046] Specifically, in the case where the laser printing device identifies that the current identification is A, a laser printing template corresponding to A is generated. The template defines how the laser printing structure 20 should be printed on the cooking utensil base body 10, including parameters such as printing position, size, direction, font and color. Finally, the laser printing device forms the laser printing structure 20 corresponding to A on the cooking utensil base body 10 according to the generated template. In this process, the laser intensity, moving speed and path can be controlled to ensure the clarity and consistency of the formed laser printing structure 20.

[0047] According to the present application, the laser printing structure 20 is a structure formed by laser printing, which can be formed on the cooking utensil base body 10 or on the coating layer, for example, the primer coating layer 40, located on the cooking utensil base body 10. In some embodiments, the cooking utensil base body 10 or the primer coating layer 40 usually has a certain color. When the laser printing structure 20 is directly formed on one of them, the color difference between the laser printing structure 20 and the transparent surface layer 30 makes the display function of the laser printing structure 20 more obvious.

[0048] According to the present application, the laser printing structure 20 includes a laser printing groove or a plurality of protrusions formed by laser printing with reference to a predetermined pattern, symbol and / or character, and can display more three-dimensional, clear and persistent related identification information under the assistance and highlighting of the transparent surface layer 30 arranged outside the laser printing structure 20.

[0049] In some embodiments, the laser printing structure 20 is composed of a plurality of protrusions formed on the cookware base 10 or the primer coating 40 by laser processing and combined into a predetermined pattern, symbol or character as identification information.

[0050] Specifically, the laser printing structure 20 includes a plurality of protrusions combined to form a structure with a predetermined pattern, symbol and / or character. In the corresponding manufacturing method, the laser printing structure 20 of the present application can be formed by removing the excess part through laser printing. The transparent surface layer is arranged on the plurality of protrusions and covers the plurality of protrusions to form a substantially flush outer surface as the outer surface of the cookware.

[0051] In other embodiments, the laser printing structure 20 is formed by etching grooves on the surface of the cookware by laser. Specifically, the laser printing structure 20 includes laser printing grooves formed by laser with reference to a predetermined pattern, symbol and / or character. The predetermined pattern can be a plurality of corrugations, diagonal strips, etc., the symbol can be a brand logo, and the character can include material, application range of the cookware (e.g., whether the cookware is suitable for washing machine cleaning), and cookware size (e.g., cookware diameter), etc. In the corresponding manufacturing method, after the laser printing grooves are manufactured, the transparent surface layer 30 is formed by coating paint on the outside of the laser printing grooves, part of the paint forming the transparent surface layer 30 will fill the laser printing grooves, and the other part will form a protective layer outside the laser printing grooves.

[0052] In these embodiments, the laser printing grooves or the plurality of protrusions formed with reference to a predetermined pattern, symbol and / or character as the laser printing structure 20 of the present application can meet the needs of the cookware for identification setting. In addition, the laser printing structure 20 is in the form of laser printing grooves, and the transparent surface layer 30 covering the outside can fill the laser printing grooves, so that the three-dimensional sense and visual effect of the laser printing structure 20 are more obvious. Furthermore, such arrangement can also increase the adhesion of the transparent surface layer 30, and the transparent surface layer 30 can also ensure the easy cleaning of the cookware, avoiding dirt and the like from being stuck in the laser printing grooves.

[0053] According to the present application, the laser printing structure 20 is arranged on the outer surface and / or the inner surface of the cookware base 10. When the laser printing structure 20 is arranged on the outer surface of the cookware base 10, it can be used to display the brand, function and size information of the product. When the laser printing structure 20 is arranged on the inner surface of the cookware base 10, it can be used to display the capacity scale, warning signs, etc.

[0054] It is known that the aluminum pot suitable for the induction cooker will have the middle area of the inner bottom wall of the pot downwardly protrude when the pot is used on the electromagnetic heating heat source for a long time, which will cause the bottom center to protrude outwardly. Due to the protrusion of the bottom center outwardly, the pot will rotate on the surface of the electromagnetic plate, which will result in the failure of the magnetic induction heating function of the pot and the pot cannot be normally used on the induction cooker.

[0055] In the prior art, a boss downwardly protruding relative to the bottom wall is arranged at the outer edge of the bottom wall of the pot base, which provides a reserved space for the deformation of the pot during use. In this way, even if the pot downwardly protrudes when the pot is used on the electromagnetic heating heat source for a long time, the pot can have a certain deformation space and will not cause poor contact with the surface of the electromagnetic plate, which will not result in the failure of the electromagnetic heating function of the pot. In addition, by arranging the boss, the strength of the bottom of the pot is enhanced to a certain extent, which can avoid large deformation of the bottom wall of the pot.

[0056] The existing printing process is generally suitable for printing on a plane. For a partially formed pot, the complete plane is relatively small and is usually limited to the area of the bottom wall of the pot, which is narrow and limits the printing. Especially for the pot with a boss on the bottom wall, the squeegee plate usually also needs to avoid the boss position, so the silk printing range is narrower and only small patterns can be silk printed, so that the bottom pattern of the prepared pot is not full.

[0057] According to the present application, by means of laser, a laser printing structure 20 can be formed on the non-planar structure, which increases the optional area for setting the mark on the pot, and the operation is flexible and efficient.

[0058] In some embodiments, the laser printing structure 20 is arranged on the outer surface of the pot base 10, in which case the transparent surface layer serves as a protective layer of the laser printing structure 20. In other embodiments, the laser printing structure 20 is arranged on the inner surface of the pot base 10, in which case the transparent surface layer not only serves as a protective layer of the laser printing structure 20, but also serves as a non-stick layer of the inner surface of the pot.

[0059] Further, the laser printing structure 20 is arranged on the outer surface of the bottom wall 11 of the pot base 10, so that during the manufacturing process, the laser printing structure 20 can be formed by clamping the edge position to fix the pot base 10. In addition, the laser printing structure 20 formed on the bottom wall 11 can meet the requirement of setting the mark while ensuring the appearance of the pot. It should be noted that the present application does not limit that the laser printing structure 20 must be arranged on the bottom wall 11 of the pot base 10, and it can be understood that those skilled in the art can arrange the laser printing structure 20 on the side wall 12, the top edge and other areas of the pot base 10 according to the teaching of the present application.

[0060] Further, as shown in FIG. 2, the laser printing structure 20 is arranged on the outer surface of the bottom wall 11 of the pot base 10, so that during the manufacturing process, the laser printing structure 20 can be formed by clamping the edge position to fix the pot base 10. In addition, the laser printing structure 20 formed on the bottom wall 11 can meet the requirement of setting the mark while ensuring the appearance of the pot. It should be noted that the present application does not limit that the laser printing structure 20 must be arranged on the bottom wall 11 of the pot base 10, and it can be understood that those skilled in the art can arrange the laser printing structure 20 on the side wall 12, the top edge and other areas of the pot base 10 according to the teaching of the present application.Figure 1 As shown, the bottom wall outer edge of the cookware base 10 is provided with a support boss 13 protruding downward relative to the bottom wall, and the laser printing structure 20 is arranged on the inner side of the support boss 13, wherein the laser printing structure 20 can ensure the display function of the cookware, and the support boss 13 can ensure that the electromagnetic heating function of the cookware is not easily lost during subsequent use.

[0061] In these embodiments, the specific arrangement area of the laser printing structure 20 on the cookware base 10 is defined, thus, the manufacturing can be facilitated, and the aesthetic appearance of the cookware can be ensured to meet the individualized needs of more user groups.

[0062] According to the present application, the transparent surface layer is formed by the surface oil of the silicone coating or fluorine coating. The silicone coating or fluorine coating has excellent high temperature resistance, weather resistance and chemical corrosion resistance, and using the surface oil of the silicone coating or fluorine coating as the material for forming the transparent surface layer 30 can further improve the performance of the cookware, such as high temperature resistance, easy cleaning and corrosion resistance.

[0063] In some embodiments, when selecting the material, the temperature tolerance of the material can also be considered. As an example, the temperature tolerance of the transparent surface layer 30 is 300-400℃, thus, the protective effect of the transparent surface layer 30 of the cookware can be ensured not to be easily lost due to high temperature. In addition, when the transparent surface layer 30 also serves as the non-stick layer of the cookware, the non-stick layer of the cookware can be prevented from being lost due to high temperature, and the non-stick effect of the cookware can be ensured.

[0064] In some embodiments, the thickness of the transparent surface layer 30 is d1, wherein 5 microns≤d1≤10 microns. With such thickness, the laser printing structure 20 can be provided with durable protection, and the durability of the display function of the laser printing structure 20 can be improved.

[0065] According to the present application, the cookware base 10 is provided with a primer coating 40, the laser printing structure 20 is formed on the primer coating 40, and the transparent surface layer 30 covers the outer side of the primer coating 40.

[0066] Specifically, the primer coating 40 is processed by using laser burning technology with reference to predetermined patterns, symbols and / or characters, and the laser printing structure 20 can be formed by engraving to be clear and durable.

[0067] In the embodiments, the primer coating 40 is used as the substrate for laser printing, so that the laser printing structure 20 formed is more clear under the contrast of the subsequent transparent surface layer 30, and the stereoscopic sense and visual effect of the laser printing structure 20 are improved. In addition, the strength of the cookware substrate 10 is not affected. In addition, the primer coating 40 can provide good adhesion, so that the laser printing structure 20 is firmly attached to the cookware substrate by the primer coating 40, and the bonding force between the transparent surface layer 30 is ensured, so that the problem of peeling of the layers of the cookware due to poor bonding force is avoided.

[0068] In some embodiments, the thickness of the primer coating 40 is d2, wherein 20 microns ≤ d2 ≤ 30 microns. If the thickness of the primer coating 40 is too thin, a uniform film layer cannot be formed, and in this case, the laser printing structure 20 cannot provide sufficient thickness, which can cause unclear or incomplete display. If the thickness of the primer coating is too thick, the bonding force between the primer coating 40 and the cookware substrate 10 can be affected due to the excessive thickness, thereby affecting the bonding performance between the layers of the cookware. In addition, the thick coating can also increase the production cost and processing difficulty.

[0069] According to the present application, the transparent surface layer 30 can be formed of transparent and high-temperature resistant paint, for example, face oil of silicone paint or face oil of fluorine paint. Of course, the present application is not limited thereto, and those skilled in the art can select other transparent and high-temperature resistant paint as the material for forming the transparent surface layer 30 under the teaching of the present application. When the transparent surface layer 30 has certain non-stickiness, the primer coating can be used as a transition layer to further improve the adhesion between the transparent surface layer 30 and the cookware substrate 10.

[0070] In some embodiments, the transparent surface layer 30 and the primer coating 40 are respectively formed of silicone paint or fluorine paint. Specifically, the transparent surface layer 30 is formed of face oil of silicone paint or face oil of fluorine paint, and the primer coating 40 is formed of bottom oil of silicone paint or bottom oil of fluorine paint.

[0071] In the present application, the top coat and the base coat of the transparent top layer 30 and the base coat 40 can be formed by using commercially available silicone or fluorine coating, or the base coat and the top coat of the transparent top layer 30 and the base coat 40 can be formed by using the base coat and the top coat described in the embodiments of the present application. As an example, the materials of the transparent top layer 30 and the base coat 40 of the present application are described in detail by taking silicone coating as an example. The main component of the silicone coating is silicone resin, which has a silicon-oxygen-silicon main chain and organic groups connected to silicon atoms, and belongs to semi-inorganic polymer, which has hydrophobicity and corrosion resistance. As an example, the components of the base coat of the silicone coating include silicone resin, epoxy resin, pigment, filler, zinc phosphate and auxiliary agent. The pigment can be titanium dioxide, cadmium red, chrome yellow, cobalt blue, and the specific color is selected according to the actual needs. The filler is glass powder, ceramic powder, mica powder and asbestos powder, etc. The auxiliary agent includes anti-settling agent (which can be fumed silica), dispersant, coupling agent (such as commonly used KH570). The silicone resin is 25-40 parts by weight, the epoxy resin is 10-15 parts by weight, the pigment is 10-15 parts by weight, the filler is 25-35 parts by weight, the zinc phosphate is 1-5 parts by weight, and the auxiliary agent is 2-8 parts by weight.

[0072] It should be noted that there is usually no big difference between the top coat and the base coat of the silicone coating in terms of composition. The main difference between the base coat and the top coat of the silicone coating is the use of pigment and the specific weight of the components. In the base coat, pigment is an indispensable part, which is used to give the coating a specific color and hiding power. However, in the top coat, the use of pigment becomes flexible, and even no pigment can be used to maintain the transparency of the coating.

[0073] In these embodiments, the base coat 40 is formed by silicone coating or fluorine coating. On the one hand, the base coat can form the laser printing structure 20 by laser burning, which is convenient for manufacturing. On the other hand, the base coat can be tightly combined with the cookware body 10 to ensure the overall bonding force of the cookware. The transparent top layer 30 is formed by silicone coating or fluorine coating, which can improve the bonding force between the base coat and the transparent top layer while ensuring the display function of the laser printing structure 20.

[0074] As shown in Figure 2 The outer surface of the cookware body 10 is provided with the base coat 40, wherein the base coat 40 is located between the cookware body 10 and the transparent top layer 30, the laser printing structure 20 is formed by laser burning of the base coat 40, and the transparent top layer 30 is formed on the lower surface of the base coat 40.

[0075] In these embodiments, the laser printing structure 20 can be formed on the base coating 40 by laser marking, so that the laser printing structure 20 is located between the base coating 40 and the transparent surface layer 30, so that the laser printing structure 20 can be prevented from being directly contacted by the outside and affected, and the risk of scratching and oxidation of the laser printing structure 20 can be avoided, and the durability of the display identification function can be improved.

[0076] According to the present application, the cookware can be suitable for open fire and can also be used on an induction cooker. The cookware further comprises a magnetic conductive layer, which is arranged between the cookware base body 10 and the base coating 40.

[0077] In these embodiments, by arranging the magnetic conductive layer, the type of heat source that the cookware can be applied to can be increased. For example, the cookware with the magnetic conductive layer can not only be suitable for open fire, but also can be used on an induction cooker.

[0078] In some embodiments, the magnetic conductive layer comprises an iron layer, a cobalt layer, or a nickel layer. The iron layer can ensure that the cookware has good heating effect when used on an induction cooker, and the manufacturing cost is relatively low. The cobalt layer can provide higher heating efficiency and better durability. The nickel layer can have higher magnetic conductive stability and can reduce the performance degradation caused by oxidation or corrosion. It should be noted that the magnetic conductive layer of the present application is not limited to this, and those skilled in the art can select other magnetic conductive layers based on actual needs, for example, a composite layer comprising one of nickel, iron, or cobalt and other non-metallic elements or metallic elements.

[0079] In these embodiments, the materials forming the magnetic conductive layer are diversified, so that suitable magnetic conductive layers can be selected based on cost, performance requirements, and application scenarios to ensure good performance and user satisfaction of the cookware when used on an induction cooker or other electromagnetic induction heating devices.

[0080] In some embodiments, the thickness of the magnetic conductive layer can be 10 microns to 100 microns. For the magnetic conductive layer with these thicknesses, it can be obtained by electroplating or chemical plating, or it can be obtained by spraying.

[0081] According to the present application, the cookware further comprises a protective layer, which covers the outer side of the magnetic conductive layer. Specifically, the material forming the protective layer can be metal or ceramic, which has good temperature stability and can provide good protection for the cookware. As an example, the thickness of the protective layer can be 5 microns to 20 microns. It should be noted that the present application does not limit that the cookware must be provided with a protective layer, and those skilled in the art can select based on actual needs.

[0082] In these embodiments, the protective layer is arranged on the outer side of the magnetic conductive layer, which can block the corrosion medium from contacting the magnetic conductive layer and ensure the service life of the magnetic conductive layer.

[0083] In some embodiments, the cookware base 10 is an aluminum base, a titanium base or an iron base. The types of cookware bases are diverse, and cookware with various performance tendencies can be manufactured based on needs. For example, when lightness is the main purpose, an aluminum base can be selected; when corrosion resistance is the main purpose, a titanium base can be selected; when the main purpose is to be rich in elements beneficial to the human body, an iron base can be selected.

[0084] According to the present application, a method for manufacturing a cooker is provided, wherein the method comprises:

[0085] Step S1: Selecting a cookware base. In some embodiments, the cookware base 10 is an aluminum base, a titanium base, or an iron base. For example, the cookware base can be an aluminum alloy base. This material is lightweight and has good thermal conductivity, making it suitable for manufacturing lightweight frying pans. The thickness of the cookware base can be selected based on actual needs. For example, the thickness of the cookware base can be 2.6-3.6 mm, which ensures that the resulting cookware has sufficient structural strength and thermal stability.

[0086] Step S2: forming a magnetic conductive layer and a protective layer.

[0087] First, a high-temperature iron powder layer is sprayed on the bottom as a magnetic conductive layer, which enables the cooker to have electromagnetic heating function. Then a high-temperature aluminum layer is sprayed as a protective layer, which further improves the overall performance of the cooker and increases its aesthetics.

[0088] Next, the outer surface of the protective layer is polished with a grinding wheel to ensure smoothness, thereby improving the adhesion of subsequent coatings. Afterwards, a layer of high-temperature resistant paint primer is sprayed as a base coat to prepare for subsequent laser marking and anti-corrosion treatment.

[0089] Then, when the primer is semi-dry, use a laser marking machine to burn a pattern on the primer.

[0090] Then, after the laser marking is completed, a layer of anti-corrosion coating topcoat is sprayed on, which not only protects the pattern from external erosion but also enhances the durability of the pot.

[0091] Sintering and Curing: After the spraying process is complete, the coating is sintered in a sintering furnace at 280°C for 15-20 minutes to fully cure and ensure its stability and durability. The coatings used for the primer and topcoat are heat-resistant. Even when heated over an open flame to around 200°C, the color does not change significantly, ensuring the cookware's aesthetics and safety. Furthermore, the topcoat is easy to clean, ensuring the cookware's cleanability.

[0092] Compared with the market, the pattern is directly printed on the outermost layer of the cooker, the laser printing structure of the cooker according to the application is not easy to be scratched during use, has the function of showing the related mark for a long time, and the user experience is good.

[0093] Although the embodiments of the present application have been described in detail above, those skilled in the art can make various modifications and changes to the embodiments of the present application without departing from the spirit and scope of the present application. However, it should be understood that these modifications and changes will still fall within the spirit and scope of the embodiments of the present application defined by the claims.
