A nozzle structure has an air pump casing to receive therein the air pump and provided with an outlet defined through a bottom face of the air pump casing and a resilient plate detachably engaging with a peripheral edge defining the outlet of the air pump casing via a guiding element such that air pumped by the air pump is able to push the resilient plate away from the outlet when air is blowing out of the air pump casing and an air pump axle extending out from the air pump is able to push the resilient plate away from engagement with the peripheral edge of the outlet to allow air to flow into the air pump casing.
