Misting fan

A misting fan, comprising:

• a fan assembly, comprising a fan housing and a fan blade assembly arranged in the fan housing, wherein the fan housing comprises an air inlet guard located at an air inlet side and an air outlet guard located at an air outlet side, the air outlet guard comprises a mist outlet portion and a plurality of air outlet vanes annularly connected about the mist outlet portion;
• and
• a misting assembly, comprising an atomizing member and a water tank, wherein the atomizing member is configured for atomizing water from the water tank to be mist, and the mist is output from the mist outlet portion;
• wherein the misting fan further comprises a main circuit board and a battery;
• the main circuit board comprises a charging management circuit, a fan driving circuit, a main control circuit, and an atomization driving circuit;
• the atomization driving circuit comprises a booster circuit;
• the booster circuit is configured to:
• receive a voltage of the battery and boost the voltage of the battery to output a driving voltage to the atomizing member, to drive the atomizing member to work;
• the driving voltage is greater than the voltage of the battery;
• the booster circuit comprises an inductor, a capacitor, and a control switch;
• a first end of the inductor is connected to a positive electrode of the battery;
• a second end of the inductor is grounded through two conducting ends of the control switch;
• a third end of the inductor is connected to a positive electrode of the atomizing member through the capacitor;
• a negative electrode of the atomizing member is connected to the second end of the inductor;
• and a control end of the control switch is connected to the main control circuit.
