Packaging device for food transportation and with humidity change real-time showing function

Abstract

The invention discloses a packaging device for food transportation and with the humidity change real-time showing function, and relates to the technical field of packaging devices. The device capablecomprises a shell, wherein a diffusion port is formed in the left side of the shell. According to the packaging device for food transportation and with the humidity change real-time showing function,because electrochromic glass and a moisture absorption block are used in cooperation, in the initial state, the moisture absorption block is dry and located at the upper end of a guide column, at themoment, the resistance of a resistor is minimum, and the current passing through the electrochromic glass is maximum, and the transparency of the electrochromic glass is maximum; when the humidity inthe shell is increased, the moisture absorption block absorbs moisture in air and thereby becoming heavier and moves downwards to drive an electric slip ring to move downwards, so that the resistanceof the resistor is increased, the current passing through the electrochromic glass is decreased, the transparency of the electrochromic glass is decreased, and the higher the humidity is, the less thetransparency is; and the effect of knowing the humidity change in real time is achieved, the humidity changes in the shell can be visually known, and the food quality can be known indirectly.

Description

technical field [0001] The invention relates to the technical field of packaging devices, in particular to a packaging device for food transportation that can detect humidity changes in real time. Background technique [0002] The packaging device for food transportation is to package the food uniformly, and to ensure that the air index in the package is kept at a constant level, effectively ensuring the quality of the food, without affecting the normal consumption of the food, thereby reducing the difficulty of food transportation. [0003] Most of the current packaging devices for food transportation are carton packaging. The cartons are cheap and the quality of the cartons is light and the drying capacity is strong. The inside of the carton is dehumidified and dried, which seriously damages the quality of food, wastes food, and increases transportation costs. [0004] Therefore, we propose a packaging device for food transportation that can detect humidity changes in rea...
