1. A wireless charging base comprising a charging panel, a first base plate, a second base plate, a first clamp a second clamp, at least one first fan and at least one second fan, wherein
the charging panel is configured to charge an electronic device, and the charging panel further comprises a first air vent and a second air vent;
when the electronic device is being charged, the first air vent is disposed on a lower surface of the charging panel, the lower surface is a surface opposite an upper surface of the charging panel that is in contact with the electronic device, and the second air vent is disposed on a side surface around the charging panel,
wherein an air duct exists between the first and second air vents;
the first base plate is disposed on the upper surface of the charging panel, located at an end of the charging panel, and is configured to support the electronic device when the electronic device is being charged, and the first base plate comprises a third air vent disposed on a first surface of the first base plate, which is closest to the second air vent;
the second base plate is disposed on the lower surface of the charging panel, located at a same end as the first base plate, and is configured to support the charging panel, and the second base plate comprises a fourth air vent disposed on a first surface of the second base plate, which is proximate to the charging panel, wherein an air duct exists between the third and fourth air vents;
the first clamp and the second clamp are disposed on side edges of the side surface around the charging panel,
wherein the first clamp comprises a fifth air vent and the second clamp comprises a sixth air vent, and
wherein an air duct exists between the fifth air vent and both the first air vent and the second air vent, and an air duct exists between the sixth air vent and both the first air vent and the second air vent;
the at least one first fan is disposed inside the charging panel, and is configured to suck air into an inside of the charging panel from the first air vent and a formed air flow flows out from the second air vent, out from the fifth air vent, and out from the sixth air vent; and
the at least one second fan is disposed inside the second base plate, and is configured to suck air into an inside of the first base plate and the second base plate from one of the third air vent and the fourth air vent, and a formed air flow flows out from another air vent of the third air vent and the fourth air vent.
