A built-in dual-purpose air pump according to claim 5, characterized in that: The air sealing plate cover (19) is provided with a spring seat, a second spring (23) is provided in the spring seat, an ejection rod (24) is slidably provided on the spring seat, the ejection rod (24) contacts the second spring (23) and can squeeze the second spring (23), the second spring (23) can always push the ejection rod (24) upward so that the ejection rod (24) contacts the air pump (2), and when the lock buckle (35) is pulled to squeeze the third spring (37), the lock buckle (35) can be separated from the fixation of the air pump (2), and synchronously, the second spring (23) will push the ejection rod (24) to eject the air pump (2).

7. A built-in dual-purpose air pump according to claim 2, characterized in that: The switch assembly (6) comprises a switch top plate (29) and a switch paddle (30), the switch top plate (29) and the switch paddle (30) being used in conjunction with each other, the switch paddle (30) being provided with a third protrusion (33) and a fourth protrusion (34), the switch top plate (29) being provided with a first protrusion (31) and a second protrusion (32), and the fourth protrusion (34) being located between the first protrusion (31) and the second protrusion (32).

8. A built-in dual-purpose air pump according to claim 7, characterized in that: When the switch paddle (30) of the air pump (2) is moved to the right, the fourth protrusion (34) pushes the first protrusion (31) to make the switch top plate (29) slide upwards and the circuit is connected. The switch assembly (6) is in a normally open state, thereby driving the air pump (2) to work. When the switch paddle (30) is moved to the middle, the switch top plate (29) can be pushed upwards manually to connect the circuit. When the switch top plate (29) is released, the circuit is disconnected. When the switch paddle (30) is moved to the left, the third protrusion (33) slides laterally against the second protrusion (32) to lock the switch top plate (29). At this time, the switch assembly (6) is in a normally closed state.
