Further, as shown in fig. 21, 22, 26, and 27, the first safe edge 912 has a height higher than that of the second safe edge 913.

As shown in fig. 26 and 27, the first side panel 93 is operatively folded inwardly of the inner case 920 and, when folded, abuts the first bottom panel 911. The first side panel 92 is operatively folded inwardly of the inner carton 920 and positioned above the first side panel 93. That is, when folding, the first side plate 93 is folded and put down, and then the first side plate 92 is folded and put down. Since the height of the first protective edge 912 is higher than that of the second protective edge 913, the first side plate 92 can be directly placed on the first side plate 93 after being folded, and cannot be interfered by the first side plate 3 and cannot be folded.

Further, as shown in fig. 21, 25, 26 and 27, the first side plate 2 has a pair of bending portions 923, the bending portions 923 are bent and extended from the edge of the first side plate 92 in the length direction toward the first side plate 3, an engaging portion 9202 is provided on the bending portions 923, the engaging portion 9202 is a plurality of bosses facing the inside of the inner box 920, an embedded groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the inner box 920. Similarly, the engaging portion 9302 is a plurality of bosses facing the outside of the inner case 920, an insertion groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the inner case 920. The boss of the engaging portion 9302 is inserted into the insertion groove of the engaging portion 9202, and the boss of the engaging portion 9202 is inserted into the insertion groove of the engaging portion 9302, thereby achieving the engaging fixation of the

first side plates

2 and 3. When folded, the first side plate 93 may be folded downward first, and the first side plate 93 falls down away from the receiving portion 9110 and is located between the two second protecting edges 913. After the first side plate 92 is folded, the two bending portions 923 are respectively abutted to the tops of the two second protecting edges 913. The first side plate 92 is covered on the first side plate 93. And a first cover 94 is operatively disposed over the first side panel 92, with a pair of opposing edges of the first cover 94 overlapping the top of the first bead 912.

In addition, as shown in fig. 21, 25, 26, and 27, the first cover 94 has a first cover body 941, and a first cold accumulation member 942 provided on the first cover body 941. The first cold accumulating member 942 may be a cold accumulating plate filled with a cold accumulating agent therein. The side of the first cover 94 facing the inside of the inner case 920 has a hook 9420 for hooking the first cold accumulation member 942, and after the

first side plates

92 and 93 are folded, the hook 9420 is operatively engaged in the first groove 9221. Thereby the volume of the folded totem incubator is smaller. The top of first curb plate 92 and first curb plate 93 all has arch 9201, and first lid body 941 inboard is equipped with recess 9411, and when first curb plate 92 and first curb plate 93 stood, first lid 94 covered first curb plate 92 and first curb plate 93 top, and the recess 9411 of first lid body 941 is inserted to the arch 9201 of first curb plate 92 and first curb plate 93, lets box 920 in first lid body 94 lid closes. For the first cover 94 to cover more tightly, there are hook bodies 9410 on the first cover body 941 that hook the protrusions 9201 of the first side plate 93. When the first side plate 92 and the first side plate 93 stand upright, that is, when the incubator is actually used.

Further, as shown in fig. 26 and 27, after the two first side plates 92 are folded, the two first side plates 92 are not overlapped, that is, the total height of the two first side plates 2 is less than or equal to the length of one first side plate 93. After the two first side plates 93 are folded, the two first side plates 93 are not overlapped, that is, the total height of the two first side plates 93 is less than or equal to the length of one first side plate 93.

As shown in fig. 21 and 26, the first side plate 92 is a long first side plate having a long length, and the first side plate 93 is a short first side plate having a short length. It will be appreciated that the first side plate 93 may be a long first side plate of a longer length and the first side plate 92 may be a short first side plate of a shorter length.

In addition, the material of the

hinges

95 and 96 is different from the material of the first side plate and the first base 91. The hinge 95 and the hinge 96 may be plastic, silicone, etc., and the first side plate and the first base 91 may be EPS, EPP foam.

In an embodiment, the hinge 5 may also be a structure of the hinge 96 to hinge the first side plate 92 and the first base 91, that is, the structure of the hinge 95 to hinge the first side plate 92 and the first base 91 and the structure of the hinge 96 to hinge the first side plate 93 and the first base 91 may be used alternatively or cooperatively with each other, which is not limited to the above examples.
