[0008] As a further embodiment of this utility model: a sealing ring is fixedly connected to the top of the inner barrel, the sealing ring is made of silicone material, and a second groove is provided on the outer side of the isolation barrel to cooperate with the sealing ring.

[0009] As a further embodiment of this utility model: the top of the support block is provided with a first slot for use with the inner barrel, and the support block is made of plastic.

[0010] As a further embodiment of this utility model: multiple sets of reinforcing rods are fixedly connected to the outer side of the outer barrel, and a top cover is snapped to the outer side of the outer barrel, with an exhaust hole provided on the top cover.

[0011] As a further embodiment of this utility model: the top of the isolation bucket is snapped with a sealing cap, and the top of the isolation bucket is provided with a second slot for use with the sealing cap.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-5 As shown, this utility model provides a high-temperature resistant layered lunch box technical solution:

[0023] The device includes an outer tub 1, with multiple sets of support blocks 4 fixedly installed on the inner side of the outer tub 1. The support blocks 4 are fixedly connected to the inner wall of the outer tub 1. The support blocks 4 have an L-shaped structure. An inner tub 8 is snapped into the support blocks 4. An isolation tub 10 is snapped into the inner tub 8. Protrusions 14 are fixedly connected to both sides of the isolation tub 10 in a symmetrical structure. A first slot 15 is opened on the top of the inner tub 8 to cooperate with the protrusions 14. An isolation ring 5 is fixedly connected to the bottom of the outer tub 1. The isolation ring 5 is located at the center of the outer tub 1. A heat insulation layer is provided between the support blocks 4. The heat insulation layer is made of aerogel felt. A heat insulation ring 6 is fixedly connected to the bottom of the outer tub 1. The outer tub 1, the support blocks 4, and the heat insulation ring 6 are all made of heat-insulating plastic material.

[0024] Specifically, users can open the lunchbox and place different foods into the inner container 8 and the isolation container 10 as needed. Due to the layered design of the inner container 8 and the isolation container 10, and the snap-fit ​​connection between the isolation container 10 and the inner container 8 via the protrusion 14 and the first slot 15, cross-contamination of flavors is effectively prevented. When hot food is placed inside, the heat-insulating plastic material of the outer container 1, the support block 4, and the heat-insulating ring 6 initially blocks heat from being transferred outwards. Furthermore, the aerogel felt insulation layer between the support blocks 4 further prevents heat from being conducted through the gaps between the support blocks 4, maintaining a high-temperature environment inside the lunchbox and achieving good heat transfer. The insulation effect is excellent; even when cold food is placed inside, it can still block external heat from entering and maintain a low temperature. The heat-insulating plastic material of the outer bucket 1, support block 4, and heat insulation ring 6 ensures that the lunchbox is not easily damaged by collisions or friction during transport. Furthermore, due to the lightweight nature of the heat-insulating plastic, it is convenient for users to carry. After use, because the surface of the heat-insulating plastic material is smooth, the outer bucket 1, support block 4, and heat insulation ring 6 can be easily cleaned with water or ordinary detergent. The inner bucket 8 and the isolation bucket 10 can also be cleaned separately. The aerogel felt is wrapped between the support blocks 4, making it less susceptible to contamination and requiring no further cleaning. Special maintenance is provided. The heat-insulating plastic has a certain strength, which can ensure that the outer bucket 1, support block 4 and heat insulation ring 6 maintain structural stability during long-term use. The L-shaped design of the support block 4, combined with the heat-insulating plastic material, can effectively support the inner bucket 8 and is firmly connected to the outer bucket 1, ensuring that the components are not easily loosened or damaged during daily use and carrying. At the same time, compared with materials such as metal, the heat-insulating plastic is lighter, making the entire lunch box easy to carry and reducing the burden on users. It is more convenient whether going to the office, traveling or going to school. The outer bucket 1, support block 4 and heat insulation ring 6 are made of heat-insulating plastic, which has a certain heat insulation capacity and can initially prevent heat from being transferred to the external environment. The aerogel felt filling between the support blocks 4 has an extremely low thermal conductivity, which can greatly reduce the heat conduction through the gaps between the support blocks 4. When facing hot food, it will not deform or release harmful substances like some heat-sensitive materials, allowing users to use it with peace of mind. The aerogel felt is also chemically stable and will not react adversely with the heat-insulating plastic or the food in the lunch box, further ensuring the safety of the lunch box during use.

[0025] A sealing ring 12 is fixedly connected to the top of the inner tub 8. The sealing ring 12 is made of silicone material. A second slot 16 is opened on the outside of the isolation tub 10 to cooperate with the sealing ring 12. A first slot 9 is opened on the top of the support block 4 to cooperate with the inner tub 8. The support block 4 is made of plastic material.

[0026] Specifically, the silicone material has good flexibility and elasticity. The silicone sealing ring 12 fixed on the top of the inner bucket 8 fits tightly with the second slot 16 on the outside of the isolation bucket 10, which can form an excellent sealing effect. When holding food, especially food with soup, it can effectively prevent soup from leaking from the connection between the inner bucket 8 and the isolation bucket 10, avoid food odor mixing, and keep the inside of the lunch box clean, preventing liquid from seeping out and soiling the user's items. Silicone can withstand high temperatures without deformation or performance degradation, which is crucial for lunch boxes that hold hot food. Even if the lunch box is filled with freshly cooked hot food, the silicone sealing ring 12 can still maintain a good seal. When assembling the lunch box, the inner bucket 8 can be easily and accurately inserted into the first slot 9, ensuring that the inner bucket 8 will not shake or shift during use, ensuring the stability of the overall structure of the lunch box. Whether in daily carrying or placement, it can effectively prevent food from spilling due to the displacement of the inner bucket 8.

[0027] Multiple sets of reinforcing rods 7 are fixedly connected to the outer side of the outer barrel 1. A top cover 2 is snapped to the outer side of the outer barrel 1. An exhaust hole 3 is provided on the top cover 2. A sealing cover 11 is snapped to the top of the isolation barrel 10. A second slot 13 is provided on the top of the isolation barrel 10 to cooperate with the sealing cover 11.

[0028] Specifically, since the reinforcing rod 7 uses the same heat-insulating plastic material as the outer bucket 1, it not only strengthens the structure but also further enhances the heat insulation performance of the lunch box. When heat is transferred outward, the reinforcing rod 7 can block the heat conduction path and reduce the heat loss to the external environment through the outer bucket 1 wall, thus better maintaining the temperature of the food inside the lunch box. It can play a positive role in keeping hot food warm or cold drinks cold, improving the heat insulation effect of the lunch box. The snap-on connection makes the connection between the top cover 2 and the outer bucket 1 tight and easy to operate. Users can easily open and close the top cover 2 for easy filling and taking out of food. At the same time, the snap-on design can ensure the airtightness of the lunch box during carrying, preventing food from spilling out and odors from entering. The presence of the vent 3 solves the pressure problem when holding hot food. When the food inside the box is hot and produces steam, the steam can be discharged through the vent 3, preventing the top cover 2 from being blown open or the lunch box from being damaged due to excessive internal pressure.

[0029] The working principle of this utility model is as follows:

[0030] First, the L-shaped support block 4 fixed inside the outer bucket 1 is connected to the inner bucket 8 by the first slot 9 at the top, providing stable support for the inner bucket 8 and ensuring that the inner bucket 8 will not shake or shift during use, thus ensuring the stability of the overall structure of the lunch box and preventing food from spilling. Inside the inner bucket 8, the isolation bucket 10 is placed by the snap-fit ​​connection of the protrusion 14 and the first slot 15, so that food can be placed in layers, effectively preventing food from mixing flavors. At the same time, the silicone sealing ring 12 at the top of the inner bucket 8 fits tightly with the second slot 16 on the outside of the isolation bucket 10, further enhancing the sealing between the inner bucket 8 and the isolation bucket 10 and preventing soup leakage.

[0031] Secondly, the outer bucket 1, support block 4, heat insulation ring 6, and reinforcing rod 7 are all made of heat-insulating plastic. This material itself has a certain strength, which can ensure that the lunch box can withstand collisions and frictions without being easily damaged during long-term use and daily carrying. At the same time, its heat insulation performance can initially block heat transfer, and can play a certain role in maintaining the temperature, whether it is hot food or cold drinks. The aerogel felt filled between the support blocks 4 has an extremely low thermal conductivity, which greatly reduces the heat conduction through the gaps between the support blocks 4. Working together with the heat-insulating plastic, it enhances the overall heat insulation effect of the lunch box. The sealing ring 12 is made of silicone material, which has good flexibility, elasticity and high temperature resistance. While ensuring the sealing effect, it can also maintain stable performance when facing hot food, and will not deform or react adversely with food.

[0032] It is worth mentioning that the reinforcing rod 7 on the outside of the outer bucket 1 not only enhances the structural strength of the lunchbox and disperses external forces to prevent deformation of the outer bucket 1, but also further improves the heat insulation performance due to its heat-insulating plastic material. The top cover 2 is connected to the outer bucket 1 by a snap-fit, which is convenient to operate and has good sealing performance, making it convenient for users to put in and take out food, while preventing food from spilling and odors from entering. The vent 3 on the top cover 2 solves the problem of pressure generated by steam inside the box when holding hot food, preventing the top cover 2 from being blown open or the lunchbox from being damaged due to excessive pressure, thus ensuring safe use. The sealing cover 11 on the top of the isolation bucket 10 cooperates with the second slot 13 to provide an independent sealed space for the isolation bucket 10, effectively preventing the odor of special-smelling foods from escaping and maintaining the original flavor of the food; finally, use When using the lunchbox, users can place different foods into the inner container 8 and the isolation container 10 according to their needs. When hot food is placed in the lunchbox, the heat insulation structure and material work together to prevent heat from being transferred outward, achieving good heat preservation. When cold food is placed in the lunchbox, it can also prevent external heat from entering, keeping it at a low temperature. The lunchbox has a stable overall structure and is lightweight, making it easy to carry. It is very convenient for going to the office, traveling or going to school. After use, each part is easy to clean due to the material properties. The outer container 1, support block 4, and heat insulation ring 6 have smooth surfaces and can be rinsed with water or ordinary detergent. The inner container 8 and the isolation container 10 can be washed separately. The aerogel felt is not easily contaminated because it is wrapped between the support blocks 4 and requires no special maintenance, providing great convenience for users.

[0033] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
