Description

technical field [0001] The invention belongs to the technical field of daily necessities detection, and in particular relates to an intelligent lunch box detection device. Background technique [0002] The pace of life of modern urbanites is relatively tense, and there are many problems with food hygiene in the society. Many urban white-collars like to use their own tableware to bring their own meals, or use their own tableware to eat. The lunch boxes in our lives are very Common, easy to carry, good sealing, can be stored at a suitable temperature for a certain period of time, to ensure that when we eat, we can ensure that we can eat warm meals, which has brought many benefits to our lives, but sometimes due to our work Too long time, forgetting and other factors cause the storage time to be too long, which will cause the food to deteriorate and cause waste, and it is not good for our body. It will cause harm to the body if it goes on for a long time. If the lunch box is w...

[0002] The pace of life of modern urbanites is relatively tense, and there are many problems with food hygiene in the society. Many urban white-collars like to use their own tableware to bring their own meals, or use their own tableware to eat. The lunch boxes in our lives are very Common, easy to carry, good sealing, can be stored at a suitable temperature for a certain period of time, to ensure that when we eat, we can ensure that we can eat warm meals, which has brought many benefits to our lives, but sometimes due to our work Too long time, forgetting and other factors cause the storage time to be too long, which will cause the food to deteriorate and cause waste, and it is not good for our body. It will cause harm to the body if it goes on for a long time. If the lunch box is washed and not dried in time, the lunch box will be wet for a long time, which will cause the growth of bacteria. When we use it next time, it will inevitably pollute the food, cause diarrhea and other phenomena, and affect our health. Food poisoning is life-threatening, and over time, I dare not use lunch boxes anymore. Therefore, a system device that can keep the lunch box environment dry for a long time and can display the temperature and time of food storage in the lunch box is needed to ensure our Late food is clean and hygienic, without pollution, has a good protection effect on our health, and has great practical value
