Neck-hung fan

Abstract

The invention relates to the field of portable heat dissipation, in particular to a neck-hanging fan which comprises a fan, a ventilation channel, a first air inlet and a first air outlet, the first air inlet and the first air outlet are communicated with the ventilation channel, the fan is arranged between the first air inlet and the first air outlet, and the first air outlet is formed in the ventilation channel. The fan runs between the first air inlet and the first air outlet to form airflow; the working air speed of part of airflow or all airflow blown out of the first air outlet is preset to be 4 meters per second or above so that disturbance of external environment fluid to the airflow can be reduced, the draught fan comprises a high-speed three-phase motor, the working voltage of the high-speed three-phase motor ranges from 3 V to 6 V, the working current of the high-speed three-phase motor ranges from 0.25 A to 8 A, and the working speed of the high-speed three-phase motor ranges from 1 m to 2 m. The rated power of the high-speed three-phase motor is 1 W to 10 W. The neck-hanging fan has the high-speed and uniform air outlet effect, so that high-speed air outlet of the neck-hanging fan is achieved, the influence of the surrounding environment and the use environment on the air outlet effect is reduced, and the use experience is further improved.
