PORTABLE FAN

The present application provides a portable fan, comprising: a housing, provided with an air inlet, an accommodating cavity, an air duct and an air outlet which are connected in sequence, the housing comprising a first side wall provided with the air outlet; a fan assembly, accommodated in the accommodating cavity, and used for blowing air from the air inlet to the air outlet via the air duct; a negative ion module, arranged on the housing, and comprising a negative ion generator, a positive electrode release part and a negative electrode release part. When the negative ion generator is working, discharge occurs between the positive electrode release part and the negative electrode release part and air is ionized so as to generate negative ions, and the negative ions are expelled from the housing. Both the positive electrode release part and the negative electrode release part are arranged, so as to avoid micro-current generation caused by short-circuiting with a human body, thus increasing product safety per
