In this embodiment, the stent 10 includes a flexible connecting section 12 and two shells 14 respectively connected to two ends of the flexible connecting section 12. The two housings 14 have the same structure and are symmetrical to each other, and one fan 16 is disposed in each housing 14. Preferably, the fan 16 is located at an end of the housing 14 remote from the flexible connecting section 12. In this embodiment, the flexible connecting section 12 and the two shells 14 are formed separately and then connected together to form the stent 10. It should be understood that in some embodiments, the two shells 14 may be directly connected to form a bracket, thereby omitting the flexible connecting section 12, or the two shells 14 may be connected to form a bracket by a rigid connecting section which is not bendable, or the flexible connecting section 12 and the two shells 14 of the bracket may be of an integral non-detachable structure.

Each of the housings 14 has a hollow structure with a partition 20 and a partition 22 provided therein. The

partitions

20 and 22 each extend along the length of the housing 14. The partition 20 divides the inner space of the housing 14 into a first cavity 24 and a second cavity 26 that are not communicated with each other, and the first cavity 24 and the second cavity 26 are arranged side by side in the left-right direction of the figure. Wherein, the first cavity 24 is located at the outer side of the casing 14, that is, the side of the casing 14 facing away from the neck of the human body; the second cavity 24 is located inside the housing 14, i.e. on the side of the housing 14 facing the neck of the person. The partition 22 is disposed in the second cavity 26, and further divides the second cavity 26 into an air duct 28 and a second sub-cavity 30 which are not communicated with each other. The air duct 28 and the second sub-chamber 30 are arranged side by side in the up-down direction of the figure, wherein the air duct 28 is located above the second sub-chamber 30. The first cavity 24, the air duct 28 and the second sub-cavity 30 are all not communicated with each other, the fan 16 is disposed in the air duct 28 and located at a terminal of the air duct 28 far from the flexible connecting section 12, and the air flow generated by the operation of the fan can only flow along the air duct 28 until the air flow is discharged out of the housing 14.
