Further, as shown in fig. 2, 6 and 7, the driving assembly further includes a first limit switch 45 and a second limit switch 46, and the first limit switch 45 and the second limit switch 46 are electrically connected to the driving motor 41. After the second cooling fin 22 moves up to the upper dead point relative to the inner container 12, the first limit switch 45 is used for controlling the driving motor 41 to stop working, and after the second cooling fin 22 moves down to the lower dead point relative to the inner container 12, the second limit switch 46 is used for controlling the driving motor 41 to stop working.

Illustratively, the first limit switch 45 is described as shown in fig. 6 and 8, and the first limit switch 45 includes a mounting base 451, a jack 452, a compression spring 453, and a trigger 454. Specifically, mount pad 451 fixed mounting is in the diapire of inner bag 12, trigger 454 installs in the one end of mount pad 451, trigger 454 and driving motor 41 electricity are connected, trigger 454 has trigger terminal 4541, when trigger terminal 4541 is compressed, trigger 454 can control driving motor 41 stop work, the one end that mount pad 451 kept away from trigger 454 is provided with two spaced apart splint 455, the through-hole has all been seted up to two splint 455, two through-holes are worn to establish by ejector pin 452, the one end and the trigger terminal 4541 butt of ejector pin 452, the other end and the bulge 481 butt of planet carrier 48 of ejector pin 452, ejector pin 452 still has the round platform 4521 that an organic whole is connected, compression spring 453 cover is located ejector pin 452, the one end and the one end butt of compression spring 453 of round platform 4521, the other end and the splint 455 butt of keeping away from trigger 454 one side of round platform 4521, the other end and the splint 455 butt of being close to trigger 454 side of compression spring 453.

In detail, as shown in fig. 2, 6, 7 and 8, when the second heat sink 22 is driven to move upwards, the driving plate 3 and the driving gear 43 rotate counterclockwise, the planet carrier 48 is driven to rotate by the clockwise force, the planet carrier 48 abuts against the push rod 452 and drives the push rod 452 to press the compression spring 453, and at this time, the elasticity of the compression spring 453 is far greater than the force applied by the planet carrier 48 so as to avoid the rotation of the planet carrier 48; when the second cooling fin 22 moves to the upper dead point, the second cooling fin 22 will not move any more, and accordingly, the driving piece 3 will not rotate any more, at this time, the driving motor 41 is still in a working state, the driving motor 41 continues to drive the transmission gear 43 to rotate, so that the transmission gear 43 drives the planet carrier 48 to rotate clockwise, the planet carrier 48 continues to push the push rod 452 to press the compression spring 453 through the protruding portion 481, at this time, the acting force of the planet carrier 48 is greater than the elastic force of the compression spring 453, so that the compression spring 453 is compressed, and therefore the other end of the push rod 452 can drive the trigger end of the trigger 454 to compress, so as to control the driving motor 41 to stop working. After the driving motor 41 stops working, since the driving motor 41 and the worm 44 have self-locking characteristics, at this time, the first driving gear 42, the second driving gear 47, the transmission gear 43 and the planet carrier 48 can be regarded as a whole, and the compression spring 453 can continuously abut against the planet carrier 48, so that the condition that the driving piece 3 is loosened due to rotation of the planet carrier 48 is avoided, and the heat dissipation effect of the heat insulation container is ensured. So that the second heat sink 22 can be always in a bonded heat dissipation state with the first heat sink 21. In addition, in the heat dissipation process of the heat preservation container, the first heat dissipation sheet 21 and/or the second heat dissipation sheet 22 may be expanded by heating, so that the second heat dissipation sheet 22 slightly moves downwards, and the driving sheet 3 rotates by a certain angle, but because the driving motor 41 and the worm 44 have self-locking characteristics, the planet carrier 48 is finally rotated, so that the ejector rod 452 is pushed to extrude the compression spring 453, that is, the compression spring 453 can absorb the deformation of the first heat dissipation sheet 21 and/or the second heat dissipation sheet 22 caused by expansion and contraction, so that the phenomenon that the driving assembly and the driving sheet 3 are blocked due to deformation is ensured, and the normal operation of the heat dissipation function of the heat preservation container is ensured, so that the heat dissipation structure for the heat preservation container has strong stability and high reliability.

Similarly, when the second cooling fin 22 moves to the bottom dead center, the driving fin 3 does not move any more, and accordingly, the driving motor 41 still operates normally, the planet carrier 48 will be forced to rotate counterclockwise and trigger the second limit switch 46 through the other side protruding portion 481, so as to control the driving motor 41 to stop working.

Of course, in other embodiments, the trigger 454 may not be provided, and the operation time of the driving motor 41 may be set, or the current level of the driving motor 41 may be detected to control whether the driving motor 41 is turned on.

Specifically, as shown in fig. 1 and 9, the thermal container further includes a base 54, a display screen 51, a temperature sensor 52, a controller 53, and a switch button 55.
