1. An air pump control system comprising:

  • an air pump for inflating or deflating an inflatable body;

    a switching driving device connected to said air pump and adapted to drive a switching between two or more air passages; and

    an air pressure sensor for detecting an internal air pressure value of said inflatable body and adapted to generate an internal pressure signal associated with said internal air pressure value and send said internal pressure signal to a central control unit;

    a position signal generating device connected to said central control unit anda first input unit connected to said central control unit and at least provided with at least one of an inflating signal input, a deflating signal input, and a deactivation signal input, said first input unit being adapted to send an inflating signal, a deflating signal or a deactivation signal to said central control unit respectively via said inflating signal input, deflating signal input or deactivation signal input;

    wherein said central control unit is connected to said air pump, said switching driving device and said air pressure sensor, and said central control unit is adapted to send a driving signal to drive said switching driving device so as to activate the switching between said air passages, and to send an activation signal or a deactivation signal to said air pump according to the internal air pressure value of said inflatable body detected by said air pressure sensor and a pre-set inflating air pressure value so as to activate or deactivate said air pump;

    wherein said position signal generating device, when triggered by said switching driving device, generates a position feedback signal and send said position feedback signal to said central control unit, and said central control unit is adapted to send a deactivation signal to said switching driving device to deactivate the switching driving device after said central control unit receives said position feedback signal from said position signal generating device;

    wherein said first input unit is further provided with a first inflating signal input, a second inflating signal input, and a third inflating signal input respectively corresponding to three different pre-set inflating air pressure values; and

    wherein when said central control unit receives an inflating signal sent by one of said first inflating signal input, second inflating signal input, third inflating signal input, and said manual inflating air pressure input and the internal air pressure value of said inflatable body detected by said air pressure sensor is less than the corresponding pre-set inflating air pressure value, said central control unit sends said driving signal to said motor driving unit to drive the air passage switching device to switch to said inflating air passage and sends said activation signal to said air pump to activate said air pump;

    when the internal air pressure value of said inflatable body detected by said air pressure sensor is greater than the corresponding pre-set inflating air pressure value, said central control unit sends said driving signal to said motor driving unit to drive the air passage switching device to switch to said deflating air passage, so as to deflate the air in the inflatable body to reach the corresponding pre-set inflating air pressure value; and

    when said central control unit receives said deactivation signal from said deactivation signal input, said central control unit sends said deactivation signal to said motor driving unit to drive the air passage switching device to switch to said closed air passage.
