Abstract: An air pump includes: a pump body defining a first opening and an air vent in different positions and an airflow channel in communication with the first opening and the air vent; a connector connected to the pump body and defining an inflation port; an airflow driving device arranged within the pump body. The airflow driving device is to perform one or more of the following operations: compressing air drawn into the pump body through the air vent and pump the air out through the inflation port; allowing the air to enter the pump body through the inflation port and be exhausted through the air vent; and driving the air to enter the pump body from the first opening, flow through the airflow channel and exit the pump body from the air vent.
