Venthole 6 is located the recess and keeps away from one side of kerve, RFIDelectronic tags 3 is locatedapron 4 one side that is close to the kerve,apron 4's relative both sides are equipped with the holding tank, the holding tank is located RFIDelectronic tags 3 relative both sides, the holding tank is equipped with gasbag 7,apron 4 is inside to be equipped with cavity 8, cavity 8 is located betweenflexure strip 5 and the RFIDelectronic tags 3, cavity 8 relative both sides are equipped with thepassageway 9 with the 7 intercommunication of gasbag that corresponds, be equipped withfirst film 10 in thepassageway 9, be equipped with water in the cavity 8,first film 10 is used for preventing that the water in the cavity 8 from getting into gasbag 7, be equipped with a plurality ofmating holes 11 onapron 4,mating holes 11 and 6 positions of venthole are external to be answered, be equipped withsecond film 12 in themating holes 11.

The bottom surface of thebox body 1 is square.

Thecover plate 4 and theelastic sheet 5 are of an integrally formed structure.

Theair outlets 6 are distributed in a matrix.

The RFIDelectronic label 3 is arranged in the middle of thecover plate 4.

Principle of embodiment:

at present, the requirement for the meal eaten by students is higher and higher, the meal is packed by lunch boxes in a kitchen and then is transported to a school for distribution, the school needs to check the time of packing the meal into a box and the temperature of the meal during receiving when receiving the meal, and the qualified meal needs to meet certain requirements, namely: the time from the boxing to the receiving of the meal cannot exceed a certain time (generally not more than 2 hours), and the temperature of the meal at the receiving time cannot be lower than a certain temperature (generally not lower than 40 ℃). The existing checking method is that lunch boxes with a certain proportion need to be taken out, and the lunch boxes are opened to measure the temperature of the food inside, which is very troublesome.

When the lunch box is used, food is placed in thebox body 1, thecover 2 is covered and fixed by the connecting mechanism, the connecting mechanism adopts the design of the existing happy button cup, the RFIDelectronic tag 3 records the boxing time, then the RFIDelectronic tag 3 tries to measure the temperature of the food, when a school receives the lunch boxes, a certain number of lunch boxes are directly taken out, then the RFIDelectronic tag 3 is scanned by the code scanning gun, the boxing time and the current temperature of the food can be directly output on a computer, and whether the food meets the eating requirements of students or not can be conveniently known without opening the lunch boxes;

when the box is packed, the temperature of the meal is high, the temperature in thebox body 1 rises, the air pressure in thebox body 1 becomes high, thecover plate 4 is tightly pressed on theair outlet hole 6, hot air is prevented from flowing out of theair outlet hole 6, and the heat preservation effect is good;

in the invention, the RFIDelectronic tag 3 and thecover plate 4 are integrated, when the cover plate needs to be replaced, theelastic sheet 5 is directly pulled out from the side groove, and then a new cover plate is arranged on the side groove and is connected with the replacement of the RFIDelectronic tag 3;

the microwave oven can be used for heating, the cover plate is taken down from the side groove during heating, then the cover is covered again, high-pressure and high-temperature steam flows out from theair outlet 6 during heating, the pressure relief effect is realized, the box body is prevented from exploding, and the cover is covered to prevent that the water loss is too fast during heating, so that the taste of the meal is influenced; see fig. 3;

when refrigeration is needed, the air pressure in the box body is reduced, when the traditional lunch box is opened, the cover is sucked on the box body, the traditional lunch box is difficult to open due to small force of students, in the invention, when the air pressure in the box body is reduced, external air enters the box body through theair outlet holes 6, theelastic sheets 5 deform, a certain gap is formed between the cover plate and the groove bottom of the groove, and the pressure difference between the inside and the outside of the box body is reduced; see fig. 4;

sometimes, students are not sensible, the lunch box is directly placed in a microwave oven for heating, and the traditional lunch box is exploded and dangerous; when the microwave oven is directly used for heating, thesecond film 12 is firstly crushed after the pressure in the box body is increased, and then high-pressure gas in the box body flows out of the matchinghole 11 and thegas outlet 6, so that the pressure relief effect is realized, and the explosion is prevented, as shown in figure 5; meanwhile, water in the cavity 8 is rapidly heated and boiled, thefirst film 10 is crushed by high-pressure steam, the steam enters the air bag, the air bag is enlarged, after the air bag is enlarged, the cover plate rotates by taking theelastic sheet 5 as a fulcrum, the cover plate is separated from theair outlet 6, the air outlet speed of theair outlet 6 is accelerated, meanwhile, a large amount of steam exists on the two opposite sides of the RFIDelectronic tag 3, and the steam absorbs energy of a part of the microwave oven to protect the RFIDelectronic tag 3.
