The whole neck hanging fan is approximately arc-shaped, the neck wearing frame 11 comprises a connecting section, a first body and a second body, the first body and the second body are detachably connected to two opposite ends of the connecting section, and the fan 12 is contained in the tail ends, far away from the connecting section, of the first body and the tail ends, far away from the connecting section, of the second body respectively. An air duct corresponding to the fan 12 and an air outlet communicated with the air duct are respectively arranged in the first body and the second body. Optionally, the air outlet includes a plurality of exhaust vents arranged at intervals along the extending direction of the corresponding body, the air duct extends along the length direction of the corresponding body, and the air flow generated by the fan 12 can flow through the air duct and be blown out from the exhaust vents, so that the air outlet area and range of the neck hanging fan are increased.

The preset held condition means that the duration of the simultaneous holding of the first holding portion 131 and the second holding portion 132 reaches a set value. When the controller 21 determines that the first holding portion 131 and the second holding portion 132 are simultaneously held and the holding time continues to reach the set value according to the data of the states in which the first holding portion 131 and the second holding portion 132 are held, if the current state of the fan 12 is on, it is predicted that the current operation of the user is to take the neck hanging fan off from the neck to prepare for use stop, and the fan 12 is controlled to be switched from on to off; if the current state of the fan 12 is off, it is predicted that the user is wearing the neck hanging fan to the neck for use, and the fan 12 is controlled to be switched from off to on.
In the above embodiment, according to the operation habit of wearing the neck hanging fan by holding both ends of the neck hanging fan with both hands of the user, the first inductive switch 231 and the second inductive switch 232 are arranged to detect the state that the holding parts at both ends of the neck hanging fan are held with both hands so as to predict the operation of the user, and the fan 12 is intelligently controlled to be turned on or off, thereby greatly improving the user experience.
