AI Technical Summary
In current cold chain transportation, it is difficult to maintain a constant internal temperature in insulated boxes, resulting in poor temperature control, and the lid is inconvenient to assemble and disassemble from the insulated box.
A temperature-controlled bag device for cold chain transportation was designed, comprising a cover plate, an air inlet pipe, a solenoid valve, a thermocouple, an exhaust port, and a shielding mechanism. The solenoid valve controls the entry of cold air, the thermocouple monitors the temperature, and the shielding mechanism regulates gas replacement to achieve a constant temperature state in the insulated box. The cover plate can be easily installed and removed through an insertion mechanism.
It achieves constant temperature control inside the insulated box, improves the temperature control effect, and simplifies the installation and disassembly process of the cover and the insulated box.
