The working principle of the invention is as follows: when the air bag device works, the inflator pump 3 inflates the air bag component 2, so that the air bag component 2 inflates to a preset pressure value; when a user sits on the sofa seat bag 1, the gravity of the user can generate a downward pressure value to act on the air bag assembly 2, the air in the air bag assembly 2 is pressed and flows through the cavity 511 along the air path pipeline 4, the air generates pressure to push the piston rod 52 to slide along the first direction so as to drive the push rod 53 to move along the vertical direction to be propped against the first limit switch 54, and the first limit switch 54 sends a corresponding instruction to control the air pump 3 to stop running, so that the air bag assembly 2 enters an exhaust state; when the pressure value in the air bag assembly 2 is reduced to a preset value, the pressure of the cavity 511 is insufficient to support the piston rod 52 to extend, the release spring 521 drives the piston rod 52 to reset, namely, the push rod 53 is reset at the moment, so that the first limit switch 54 is reset, the air exhaust is stopped, the inflator pump 3 operates, the air bag assembly 2 enters an inflated state, the sofa seat bag 1 is restored to an ideal state, and the air bag assembly 2 is inflated; compared with the intelligent sofa in the prior art, the intelligent control sofa can automatically adjust the pressure value of the air bag component 2 through the feedback pressure of the air bag component 2, so that the pressure of the air bag component 2 tends to a dynamic balance value, the hardness of the sofa seat bag 1 is adjusted, a sensor and repeated manual adjustment of a user are not required, the use of the user is convenient, and the comfort level of the user is improved.
