Description

Technical Field

[0001] The utility model relates to the technical field of plant high-fiber pulp self-heating and leak-proof lunch boxes, and more specifically, to a plant high-fiber pulp self-heating and leak-proof lunch box. Background Art

[0002] In the current technological development of environmentally friendly tableware, plant high-fiber pulp self-heating and leak-proof lunch boxes have attracted market attention due to their convenience and environmental protection characteristics. This lunch box integrates a self-heating function, which can provide heating for food without relying on an external heat source. However, while this self-heating function brings convenience, it also brings certain safety challenges. During use, a lot of steam will be generated inside the lunch box. If this steam cannot be discharged in time in the sealed lunch box, it will cause the internal pressure to increase, which may cause safety accidents and pose a potential safety threat to users.

[0003] In order to ensure safety during use, leak-proof lunch boxes are usually required to have good sealing performance to prevent food leakage. However, this sealing performance is in conflict with the need for steam discharge. If the seal is too strict, the steam cannot be discharged in time, which may cause the lunch box to deform or even explode, causing harm to the user. Utility Model Content

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a self-heating and leak-proof lunch box made of plant high-fiber pulp, which has the following beneficial effects:

[0017] 1. The design of the deflation mechanism ensures that the plant high-fiber pulp self-heating leak-proof lunch box can effectively discharge the steam generated inside during use, thereby avoiding safety hazards caused by excessive pressure. Through the linkage mechanism of the telescopic rod and the synchronous disk, when the internal pressure increases, the telescopic rod slides to drive the synchronous disk to move, and then pulls the pull rod to compress the spring, so that the seal between the one-way disk and the fitting groove can be released, and the steam can be discharged smoothly. This design enables the lunch box to automatically adjust the internal pressure while maintaining a seal, greatly improving safety during use.

[0018] 2. The one-way mechanism realizes one-way control of steam discharge through the cooperation of the one-way plate and the fitting groove, ensuring that the steam can only be discharged in one direction without reverse leakage. This design enables the spring to automatically return to its original state after the pressure is released and reseal the fitting groove, effectively preventing foreign matter from entering the lunch box and maintaining the sealing performance of the lunch box. The existence of the one-way mechanism enables the lunch box to achieve an automatic balance between pressure relief and maintaining sealing, thereby improving the overall safety and reliability of the lunch box.

[0019] 3. The sealing mechanism plays a key role in ensuring the leak-proof performance of the lunch box. Through the cooperation of the sealing cover and the clamping sleeve, as well as the setting of the partition and the through hole, the lunch box can maintain a good sealing state during the heating process to prevent food leakage. At the same time, the design of the sealing mechanism also takes into account the need for steam discharge, so that the steam will not destroy the sealing performance of the lunch box when it is discharged. This design not only ensures the hygiene and safety of food, but also improves the convenience of using the lunch box, providing consumers with a safe, reliable and easy-to-operate catering solution.
