Air pump device adapted to small-sized inflatable product and inflatable product

Abstract

An air pump device adapted to a small-sized inflatable product includes a support, a rotary fan rotatably disposed on the support and a ventilation rotary drum for connecting the inflatable product rotatably disposed on the support. One side of the ventilation rotary drum is provided with a ventilation interface capable of rotating with the ventilation rotary drum. An inflation port and a deflation port are formed in the support. A first centrifugal fan blade and a second centrifugal fan blade are coaxially distributed on the opposite two sides of the rotary fan respectively. The inflation port communicates with the exhaust end of the first centrifugal fan blade, the deflation port communicates with the suction end of the second centrifugal fan blade, and the ventilation interface can be driven to communicate with the inflation port and the deflation port respectively by the rotation of the ventilation rotary drum.
