Description

technical field [0001] The invention relates to the technical field of self-service vending machines, in particular to a grain self-service vending machine based on the Internet of Things. Background technique [0002] Rice, soybeans, mung beans, etc. are the necessary grains for people's daily diet. When people need to eat these grains, they usually need to go to supermarkets, farmers' markets, convenience stores, etc. to purchase, whether purchasing large bags or small quantities of bulk weighing, all need It takes a lot of time to travel back and forth between homes and shopping malls; moreover, grains are inconvenient to be stored for a long time, and people prefer the mode of purchasing in small quantities and buying them after they are used up. In this way, there is bound to be a waste of time, energy and even transportation costs; and it is difficult to purchase in a quantitative or fixed amount, which is inconvenient. Self-service vending machines have become a very...

AI Technical Summary

Problems solved by technology

When the grain is piled up for a long time, it usually produces a lot of heat and moisture with respiration, and the vending machine is placed in an outdoor environment, which is also easily affected by the environment, resulting in high internal humidity, which will cause mold or rot of the grain.

This technology adopts a sealed environment packaging method. Although it can reduce the adverse effects of the external environment on the grain to a certain extent, it also hinders the internal heat and moisture from dissipating. It only proposes to install a detection device without giving specific details. Solution, there are technical deficiencies

[0004]At the same time, since the sealing cover is fastened on each storage box, the top of the cabinet body is fastened with a top cover, and the cabinet body is usually high, when a certain When different types of grain need to be added, the adding personnel need to stand at a high place with the help of a ladder and other tools to open the top cover, and then remove the sealing cover on the corresponding storage box, and then pour a certain weight (such as 10KG) of grain into the storage material In the storage box, the adding process is inconvenient and dangerous, and because the amount of grains contained in the storage box is usually not very large, there are situations where frequent additions are required, which adds a lot of workload to the adding personnel
