When the user does not need to use the neck hanging fan, the sealing plug 12 can be opened and then the air can be exhausted from the bag body 10. When the user needs to use the neck hanging fan again, the bag cavity 11 may be inflated, and it should be noted that the inflation process may be from the outside of the bag body 10 to the inside of the bag cavity 11, or may be performed inside the bag body 10, which is not limited herein. If inflation is performed from outside the bladder 10, the fluid port may act as an inflation port.

Specifically, as shown in fig. 2 and 3, the capsule 10 is provided with a fixing ring 13 protruding from the fluid port, the fixing ring 13 extends along the circumferential direction of the fluid port, and the sealing plug 12 is in sealing engagement with the fixing ring 13. The fixing ring 13 may be protruded from the inner wall surface of the bag body 10, or may be protruded from the outer wall surface of the bag body 10, which is not limited herein, and only needs to extend along the circumferential direction of the fluid port. The sealing plug 12 is matched with the fixing ring 13, so that the matching area can be increased, and the sealing performance of the fluid port is improved. For example, the inner wall of the bag 10 may be protruded with a first fixing ring 13, and the outer wall of the bag 10 may be protruded with a second fixing ring 13, so as to further improve the sealing stability.

In one embodiment, as shown in fig. 2 and 3, the neck portion and the fan main body 20 enclose to form a neck hanging space 30, and the fluid port is opened on a sidewall of the bag 10 facing away from the neck hanging space 30. The neck hanging space 30 is used for the neck to wear, so that the whole neck hanging fan is hung around the neck. The side wall of the bag body 10 facing away from the neck hanging space 30, i.e. the side wall facing the skin of the neck after wearing, is provided with the fluid port, so that the sealing plug 12 can be prevented from contacting the skin, and the wearing comfort of the neck hanging fan can be improved.
