A vacuum layer is formed between the first heat preservation layer and the second heat preservation layer, and a heat preservation cavity is formed between the second heat preservation layer and the third heat preservation layer.

[0006] In some embodiments, the first heat preservation layer, the second heat preservation layer and the third heat preservation layer are all stainless steel layers.

[0007] In some embodiments, the appliance heat preservation structure further includes an extension body, the extension body is located outside the heat preservation cavity and the vacuum layer, and the extension body encloses to form an auxiliary heat preservation space located outside the heat preservation cavity and the vacuum layer.

[0008] In some embodiments, the extension body is arranged along the side wall direction and extends in a direction away from the heat preservation cavity and the vacuum layer.

[0009] In some embodiments, the auxiliary heat preservation space is located on the back side of the bottom wall, and the cross-sectional shape of the auxiliary heat preservation space is circular.

[0010] In some embodiments, the extension body is a structure on the first heat-insulating layer, or the extension body is a structure on the second heat-insulating layer, or the extension body is a structure on the third heat-insulating layer.

[0011] In some embodiments, the third heat-insulating layer is provided with a sunken part, the sunken part has an upper edge, a lower edge and an inclined edge connecting the upper edge and the lower edge, and there is a height difference between the upper edge and the lower edge.

[0012] The present application also provides a heat-insulating appliance, including an appliance main body, and the appliance main body is provided with the above-mentioned appliance heat-insulating structure.

[0013] In some embodiments, the appliance main body has a heat-insulating cavity and a device cavity, the appliance heat-insulating structure is provided with an extension body extending into the device cavity, and the extension body encloses to form an auxiliary heat-insulating space located in the device cavity.

The handle is connected to the appliance main body, the electric heating device and the first battery assembly are installed in the appliance main body, the second battery assembly is installed in the handle, and the first battery assembly and the second battery assembly are used to supply power to the electric heating device.

[0015] Compared with the above background art, the appliance heat-insulating structure provided by the present application mainly includes a first heat-insulating layer, a second heat-insulating layer and a third heat-insulating layer. The first heat-insulating layer and the second heat-insulating layer are located on the side wall of the appliance, the third heat-insulating layer is located on the bottom wall of the appliance, the first heat-insulating layer, the second heat-insulating layer and the third heat-insulating layer are fixedly connected at the intersection position of the side wall and the bottom wall, a vacuum layer is formed between the first heat-insulating layer and the second heat-insulating layer, and a heat-insulating cavity is formed between the second heat-insulating layer and the third heat-insulating layer.

[0016] The appliance heat-insulating structure provided by the present application is an innovative heat-insulating technology, and its design mainly includes three heat-insulating layers, namely a first heat-insulating layer, a second heat-insulating layer and a third heat-insulating layer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0026] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0027] Please refer to Figure 1 and Figure 2 , where Figure 1 is the structural diagram of the appliance heat preservation structure and the heat preservation appliance provided by the embodiment of the present application, Figure 2 is Figure 1 the enlarged view of the appliance heat preservation structure in

[0028] In the first specific implementation manner, the appliance heat preservation structure 100 provided by the embodiment of the present application mainly includes a first heat preservation layer 11, a second heat preservation layer 12, and a third heat preservation layer 13. The first heat preservation layer 11 and the second heat preservation layer 12 are located on the side wall 201 of the heat preservation appliance 200, while the third heat preservation layer 13 is located on the bottom wall 202 of the heat preservation appliance 200. These heat preservation layers are integrally formed by fixed connection at the intersection position of the side wall 201 and the bottom wall 202. A vacuum layer 2101 is formed between the first heat preservation layer 11 and the second heat preservation layer 12, and a heat preservation cavity 2102 is formed between the second heat preservation layer 12 and the third heat preservation layer 13.

[0029] The appliance heat preservation structure 100 provided by the present application is an innovative heat preservation technology. Its design mainly includes three heat preservation layers, namely the first heat preservation layer 11, the second heat preservation layer 12, and the third heat preservation layer 13. The purpose of this structure design is to optimize the heat preservation performance and reduce the production cost. In this structure, the first heat preservation layer 11 and the second heat preservation layer 12 are arranged on the side wall 201 of the heat preservation appliance 200, while the third heat preservation layer 13 is located on the bottom wall 202. These three heat preservation layers are tightly combined by fixed connection at the junction of the side wall 201 and the bottom wall 202 to form a seamless heat preservation system.

[0030] Specifically, a vacuum layer 2101 is formed between the first heat-insulating layer 11 and the second heat-insulating layer 12, while a heat-insulating cavity 2102 is formed between the second heat-insulating layer 12 and the third heat-insulating layer 13. Since the vacuum layer 2101 lacks air, which is a good conductor of heat, it can effectively insulate heat and reduce heat transfer. The heat-insulating cavity 2102 is a space for storing liquids or foods that need to be kept warm, and its design helps to maintain a stable internal temperature. A remarkable feature of the appliance heat-insulating structure 100 of the present application is that it abandons the traditional indirect connecting piece, which is usually used to connect the side wall 201 and the bottom wall 202. Removing the indirect connecting piece not only simplifies the production process and reduces the manufacturing cost, but also maintains the continuity of the heat-insulating structure, avoiding additional heat loss that may be brought by the connecting piece, thereby improving the overall heat-insulating effect. This design not only improves the performance of the heat-insulating appliance 200, but also meets the market demand for energy-efficient products.

[0031] Combined with the above structure and process description, it can be seen that the appliance heat-insulating structure 100 has at least the following beneficial effects: the appliance heat-insulating structure 100 abandons the indirect connecting piece between the side wall 201 and the bottom wall 202, achieving the purpose of reducing the material cost, and also ensuring the continuity of the heat-insulating structure outside the heat-insulating cavity 2102, thereby improving the overall heat-insulating effect.

[0032] Optionally, the first heat-insulating layer 11, the second heat-insulating layer 12, and the third heat-insulating layer 13 are all stainless steel layers; at the intersection of the side wall 201 and the bottom wall 202, the first heat-insulating layer 11 and the second heat-insulating layer 12 are welded and fixed and then welded and fixed to the third heat-insulating layer 13.

[0033] In this embodiment, the constituent materials of the appliance heat-insulating structure 100 have specific selections: the first heat-insulating layer 11, the second heat-insulating layer 12, and the third heat-insulating layer 13 are all made of stainless steel. This material selection is not only due to its durability and easy cleaning characteristics, but also because stainless steel has good heat-insulating performance and structural strength.

[0034] At the junction of the side wall 201 and the bottom wall 202 of the heat-insulating appliance 200, these three heat-insulating layers are fixedly connected by welding. Specifically, first, the first heat-insulating layer 11 and the second heat-insulating layer 12 are welded together to ensure a tight combination between them, and then this combination is welded and fixed to the third heat-insulating layer 13. Such a welding process not only ensures the stability and sealing of the overall structure, but also further reduces the production cost and improves the heat-insulating effect by eliminating the use of indirect connecting pieces.

[0035] In some embodiments, the design of the appliance insulation structure 100 further includes an extension body 14. This extension body 14 is designed outside the insulation cavity 2102 and the vacuum layer 2101, and its function is to create an additional auxiliary insulation space, thereby enhancing the overall insulation effect.

[0036] Although the extension body 14 is a structure outside the insulation cavity 2102, the extension body 14 indirectly improves the insulation performance of the insulation cavity 2102. Specifically, the extension body 14 encloses to form a space outside the insulation cavity 2102 and the vacuum layer 2101. The extension body 14 and its auxiliary insulation space can block the heat dissipation in the space outside the insulation cavity 2102, thereby indirectly reducing the heat dissipation in the insulation cavity 2102, so as to improve the overall insulation performance.

[0037] It should be noted that the extension body 14 can be a structure on the first insulation layer 11, or the extension body 14 can be a structure on the second insulation layer 12, or the extension body 14 can also be a structure on the third insulation layer 13. Therefore, the extension body 14 can be extended from any one of the first stainless steel layer, the second stainless steel layer, and the third stainless steel layer, and all should fall within the scope of the description of this application.

[0038] In some embodiments, the design of the extension body 14 has a specific direction and position. The extension body 14 is arranged along the direction of the side wall 201, and its extending direction is away from the insulation cavity 2102 and the vacuum layer 2101. Figure 2 For example, the extension body 14 is arranged vertically downward.

[0039] In addition, the auxiliary insulation space is arranged on the back side of the bottom wall 202, and the cross-sectional shape of this space is designed as a circle. The circular design is not only more structurally robust but also helps to evenly distribute heat, making the insulation effect more comprehensive and consistent. The circular cross-section of the auxiliary insulation space also helps to simplify the manufacturing process because circular structures are usually easier to form and process during production.

[0040] In some embodiments, the third insulation layer 13 is provided with a sinking portion 13. The sinking portion 13 has an upper edge, a lower edge, and an inclined edge connecting the upper edge and the lower edge, and there is a height difference between the upper edge and the lower edge.

[0041] In this embodiment, the sinking portion 13 is a special design on the third insulation layer 13, and the sinking portion 13 is located on the side of the third insulation layer 13 facing the insulation cavity 2102. The design details of this sinking portion 13 include having an upper edge, a lower edge, and an inclined edge connecting the upper edge and the lower edge. Such a structure forms a height difference between the upper edge and the lower edge, and this height difference provides additional structural features and functional advantages for the insulation appliance 200.

[0042] First, the existence of the height difference can provide more space for the thermal insulation appliance 200 to store the contents to be thermally insulated, while keeping the external dimensions of the appliance unchanged. Secondly, the sunken part 13 may help to improve the thermal insulation effect because its structure can reduce the heat loss through the bottom. In addition, by providing the sunken part 13, the problem of deformation of the third thermal insulation layer 13 caused by welding the electric heating device 23 to the third thermal insulation layer 13 can be avoided.

[0043] This application also provides a thermal insulation appliance 200, including an appliance main body 21, and the appliance main body 21 is provided with the above-mentioned appliance thermal insulation structure 100.

[0044] The thermal insulation appliance 200 can be in the form of a thermos cup, a thermal insulation pot, etc., which is not limited in this embodiment. The thermal insulation appliance 200 is provided with the above-mentioned appliance thermal insulation structure 100 and should have all the beneficial effects of the above-mentioned appliance thermal insulation structure 100, which will not be elaborated here.

[0045] In some embodiments of the thermal insulation appliance 200, the design of the appliance main body 21 includes two main chambers: a thermal insulation chamber 2102 and a device chamber 2103. The thermal insulation chamber 2102 is used to store items to be thermally insulated, such as beverages or foods, while the device chamber 2103 may be used to store other components or devices, such as heating elements or electronic devices.

[0046] One feature of the appliance thermal insulation structure 100 is that it is provided with an extension body 14, and this extension body 14 is designed to be able to extend into the device chamber 2103. The extension body 14 encloses a space in the device chamber 2103. Although this space is outside the thermal insulation chamber 2102, the extension body 14 and its auxiliary thermal insulation space can block the heat loss in the space outside the thermal insulation chamber 2102, that is, in the device chamber 2103, thereby indirectly reducing the heat loss in the thermal insulation chamber 2102, so as to improve the overall thermal insulation performance.

[0047] In some embodiments, the thermal insulation appliance 200 further includes a handle 22, an electric heating device 23, a first battery assembly 24 and a second battery assembly 25. The handle 22 is connected to the appliance main body 21, the electric heating device 23 and the first battery assembly 24 are installed in the appliance main body 21, the second battery assembly 25 is installed in the handle 22, and the first battery assembly 24 and the second battery assembly 25 are used to supply power to the electric heating device 23.

[0048] Among them, both the electric heating device 23 and the first battery assembly 24 are located in the device chamber 2103, and the extension body 14 is arranged around the outer periphery of the electric heating device 23. The length dimension of the extension body 14 is not limited here.

[0049] In this embodiment, the thermal insulation appliance 200 also has an electric heating function. An electric heating device 23 is installed inside the appliance main body 21, enabling the thermal insulation appliance 200 to not only keep warm but also heat the beverages or foods stored inside.

[0050] In terms of power supply, the thermal insulation appliance 200 is powered by two sets of battery components: the first battery component 24 and the second battery component 25. The first battery component 24 is installed inside the appliance main body 21, while the second battery component 25 is ingeniously installed inside the handle 22. Such a layout design makes the installation of the battery components more reasonable and at the same time provides the necessary power source for the electric heating device 23.

[0051] Generally speaking, through this integrated design, the thermal insulation appliance 200 realizes the combination of heat preservation, heating, and portability.

[0052] It should be noted that many components mentioned in this application are all common standard components or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods.

[0053] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0054] The above has introduced in detail the appliance thermal insulation structure and the thermal insulation appliance provided in this application. Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of this application, several improvements and modifications can still be made to this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
