Abstract

An air pump control system includes an air pump for inflating or deflating an inflatable body; a switching driving device connected to the air pump for driving the switching between two or more air passages; and an air pressure sensor for detecting an internal air pressure value of the inflatable body, and sending an internal pressure signal to a central control unit, which is connected to the air pump, the switching driving device, and the air pressure sensor. The central control unit sends a driving signal to the switching driving device to activate the switching between the air passages, and sends an activation or deactivation signal to the air pump according to the detected internal air pressure value and a pre-set inflating air pressure value, to control the activation or deactivation of the air pump. An air pump control method adapted to the above air pump control system is provided.

First claim

What is claimed is:

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 and
a 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.

3. The air pump control system of claim 2 , wherein said air passages comprise an inflating air passage, a deflating air passage and a closed air passage.

4. The air pump control system of claim 2 , wherein said position signal generating device is adapted to send a position feedback signal to said central control unit when said switching driving device is switched to an inflating air passage, a deflating air passage or a closed air passage, respectively, and said central control unit is adapted to send a deactivation signal to said switching driving device according to the received position feedback signal.

5. The air pump control system of claim 1 , wherein said switching driving device is an electromagnetic valve, and said central control unit is adapted to send a driving signal to said electromagnetic valve according to said inflating signal, deflating signal or deactivation signal so as to switch said electromagnetic valve to the respective inflating air passage, deflating air passage or closed air passage.

6. The air pump control system of claim 1 , wherein said first input unit is further provided with a manual inflating air pressure input for manually setting an inflating air pressure value.

7. The air pump control system of claim 1 further comprising:
a first display unit connected to said central control unit and adapted to receive a display signal generated by said central control unit.

8. The air pump control system of claim 7 , wherein said display signal comprises at least one operating state of said air pump control system, said at least one operating state including one or more of an inflating state, a deflating state, a pre-set inflating air pressure value, a pre-set deflating air pressure value, a current air pressure value, a normal operating state, and an abnormal operating state.

9. The air pump control system of claim 1 further comprising:
