The fan assembly may be located inside the air duct 13 or outside the air duct 13, which is not limited herein, and only needs to allow the airflow generated by the fan assembly to enter the air duct 13. The specific form of the fan assembly and the manner of installation in the air duct 13 are not limited, and only the requirement for the drivable air flow is satisfied. The positions of the air inlet 11 and the air outlet 12 are not limited, and only the requirement of communication with the air duct 13 is met, and the extending track of the air duct 13 is not limited, and only the requirement of integral expansion after air flow enters is met. The inflated airbag 10 can be freely bent, and thus the airbag 10 can be bent into a shape adapted to the neck to be hung on the neck. The balloon 10 has elasticity to expand an expansion volume by stretching when inflated.

The airbag 10 contracts when not inflated, and expands when inflated. The airbag 10 in the deflated state is less bulky and can be folded into a shape that takes up less space. The air bag 10 in the inflated state can automatically form a ring shape or a U shape to enclose the neck hanging space 20.
