[0002] An inflatable mattress refers to a mattress that expands in volume after being inflated. It has the characteristics of strong flexibility and good elasticity. Since it is easy to carry and use after being deflated, it is widely used in various fields, especially in outdoor products. In order to facilitate the inflatable mattress to be inflated and deflated, an inflatable air pump is generally provided on the inflatable mattress. In order to further improve the convenience, the inflatable air pump provided on the inflatable mattress is generally powered by a battery. In order to ensure the volume and weight of the inflatable mattress after being deflated, the battery of the inflatable air pump cannot be too large. Therefore, the inflatable air pump needs to replace the battery or charge after the inflatable mattress is fully inflated and deflated several times. When replacing the battery, since the existing battery is generally connected to the air pump by a cover plate with a buckle, it is inconvenient to replace, so a inflatable air pump that is easy to replace the battery is needed.
