[0055] When the reversing plate 610 moves to the first preset position, the vent hole 612 docks with the air outlet hole 360 ​​of the first unit 300, then the first vent 110 is the air outlet of the electric air pump 1, and the second vent 210 is the air inlet of the electric air pump 1. At this time, the air duct in the electric air pump 1 is an air duct for inflation; when the reversing plate 610 moves to the second preset position, the vent hole 612 docks with the air inlet hole 370, then the air duct in the electric air pump 1 is switched, the first vent 110 is converted into the air inlet of the electric air pump 1, and the second vent 210 is converted into the air outlet of the electric air pump 1. At this time, the air duct in the electric air pump 1 is an air duct for deflation.

[0058] Initially, the reversing plate 610 is in the first preset position. When the deflation control button 560 is pressed, the support rod 630 moves downward by a certain distance, and the reversing cam 660 rotates by a certain angle, so that the reversing plate 610 moves downward by a certain distance to the second preset position. Therefore, in this embodiment, the reversing cam 660 and the support rod 630 realize the reciprocating motion of the reversing plate 610.

[0059] The reversing spring 650 is disposed between the reversing plate 610 and the housing 100 to buffer vibration.

In an operation process, when the deflation control button 560 is pressed, the undercut 670 is buckled with the support rod 630, so that the deflation control button 560 cannot be reset immediately, until the air pressure detection unit 520 detects that the internal air pressure of the inflatable product reaches a preset value, and then the solenoid valve 680 pushes the undercut 670 to separate the undercut 670 from the support rod 630.

[0061] A ramp rod 613 is provided at the vent hole 612 of the reversing plate 610, and a valve assembly 170 is provided at the first vent 110.
