The working principle of the inflation and deflation device of the embodiment is as follows:

when the airbag 3 needs to be inflated, the control module controls the second electromagnetic valve 10 and the third electromagnetic valve 11 to be closed, the first electromagnetic valve 9 is opened, and because the air pressure in the high-pressure air storage tank 5 is higher than the air pressure in the airbag 3, the air in the high-pressure air storage tank 5 can be filled into the airbag 3 to expand the volume of the airbag 3 until the air pressure in the airbag 3 reaches a preset value (an air pressure sensor is arranged in the airbag 3), and the first electromagnetic valve 9 is closed; when the air bag 3 needs to be deflated, the control module controls the first electromagnetic valve 9 to be closed, the second electromagnetic valve 10, the third electromagnetic valve 11 and the vacuum pumping pump 8 are opened, and because the air pressure in the low-pressure air storage tank 6 is lower than the air pressure in the air bag 3, the air in the air bag 3 can be filled into the low-pressure air storage tank 6 to reduce the volume of the air bag 3 until the air pressure in the air bag 3 reaches a preset value, and the second electromagnetic valve 10, the third electromagnetic valve 11 and the vacuum pumping pump 8 are closed.
