A first air opening and a second air opening that are interconnected, and an independent air opening are disposed on the pump casing, the first air opening is used for communication with the outside world, and the second air opening and the independent air opening are used for communication with independent inflation cavities of an inflatable product; and the centrifugal fan is arranged inside the pump casing, and an air inlet end of the centrifugal fan is communicated with the first air opening. Using the centrifugal fan and the diaphragm pump inside a same fan, the two independent inflation cavities may be inflated based on different pressure requirements.
