The first output shaft 251 is connected to the connection rod 24, and the second output shaft 251 is connected to the fan blades 26. The part of the case body 1 close to the fan blades 26 is provided with vents 13.
By controlling the forward and reverse rotation of the driving unit 25, the connection rod 24 and the piston 22 can be reciprocated inside the inflator 21 to inflate. In addition, the air pump 2 generates heat when working, but the driving unit 25 can drive the fan blades 26 to rotate to discharge the hot air generated inside the case body through the vents 13, avoiding the working process of the air pump 2 being affected by the excessively high ambient temperature.
Further, the first output shaft 251 of the driving unit 25 is connected to the connection rod 24 through the gear assembly 7 in a transmission way.
Specifically, the gear assembly 7 includes a first gear 71, a second gear 72 and a third gear 73. The first gear 71 is connected to the first output shaft 251 of the driving unit 25.
