In this way, the front cover 200 can smoothly open the opening of the evaporator thermal insulation box 100 while preventing the front cover 200 from rapidly jumping out of the evaporator thermal insulation box 100 due to the air pressure, thereby improving the safety of the pressure release process, and after the front cover 200 is opened, the opening can have a large pressure release area to improve the pressure release efficiency, and of course, it is preferable that a plurality of protective strings 400 be uniformly disposed between the bottom of the evaporator thermal insulation box 100 and the bottom of the front cover 200 in order to enhance the connection strength and stability between the evaporator thermal insulation box 100 and the front cover 200 and prevent the front cover 200 from jumping out due to the breakage of the protective string 400.

As shown in fig. 6, optionally, a receiving cavity 401 is provided on the evaporator thermal insulation box 100 or the front cover 200, and the protection rope 400 is rolled and contracted in the receiving cavity 401 under the condition that the front cover 200 covers the opening of the evaporator thermal insulation box 100. Therefore, the influence of the protective rope 400 on the carrying or moving process of the evaporator thermal insulation box body 100 can be reduced, and the situation that the protective rope 400 is wound to influence the use of the evaporator thermal insulation box body 100 is avoided, so that the protective rope 400 can be better and more regularly connected between the evaporator thermal insulation box body 100 and the front cover 200.

The embodiment also provides an active temperature control container, which comprises the emergency pressure relief mechanism.

By adopting the active temperature control container provided by the embodiment of the disclosure, the evaporator thermal insulation box body 100 with an opening is arranged, the detachable front cover 200 is arranged on the opening, the movable connecting assembly 300 is arranged between the evaporator thermal insulation box body 100 and the front cover 200, the movable connecting assembly 300 fixedly connects the front cover 200 and the evaporator thermal insulation box body 100 under the condition that the pressure of an aircraft cabin is stable, at the moment, the front cover 200 is in a state of sealing the evaporator thermal insulation box body 100, the front cover 200 can block the connection between the internal environment and the external environment of the evaporator thermal insulation box body 100, thereby not only avoiding the air leakage of the evaporator thermal insulation box body, but also enabling the evaporator thermal insulation box body 100 to have better thermal insulation performance, and when the aircraft cabin is in a pressure loss state and needs emergency pressure relief, because the internal pressure of the evaporator thermal insulation box body 100 is higher than the external pressure thereof, the front cover 200 receives the outside pressure of inside atmospheric pressure this moment, thereby make the separation of movable connection subassembly 300 under the effect of the inside pressure of evaporimeter insulation box 100, front cover 200 is opened, the inside gas of evaporimeter insulation box 100 is discharged by the opening, accomplish the pressure release, and then utilize the pressure release mode that the front cover 200 of evaporimeter insulation box 100 can be opened, for setting up the pressure release hole that runs through the box alone, make its inside gas discharge by the opening fast through the front cover 200 of opening evaporimeter insulation box 100, and the opening can increase the pressure release area, make evaporimeter insulation box 100 can accomplish pressure release in the twinkling of an eye, the pressure release is more rapid, the pressure release efficiency is improved, and front cover 200 covers and blocks the opening of evaporimeter insulation box 100, the leakproofness of evaporimeter insulation box 100 has been strengthened, the thermal insulation performance of evaporimeter insulation box 100 has been guaranteed effectively.
