The self-charging and discharging bubble chamber supporting framework according to claim 4, wherein a first snap ring and a second snap ring are arranged on the inner side wall of the self-sealing overflow pipe, the first snap ring and the second snap ring are arranged on the side far away from the sealing end of the self-sealing overflow pipe, the first snap ring is arranged on the side of the charging end, and a bulge is arranged on the second end of the discharging spoon; when the inflatable product is in a non-exhaust state, the first clamping ring is clamped and connected with the bulge, at the moment, the internal pressure of the inflatable product is higher than the external pressure, and the sealing end of the self-sealing overflow pipe is in a sealing state under the action of the internal pressure of the inflatable product; when the exhaust state, second snap ring and protruding card are put and are connected, and at this moment, the second end of drainage spoon will prop open the gap from the sealed end of proclaiming oneself the overflow pipe, destroy the self-sealing state of proclaiming oneself the overflow pipe, because the internal pressure of inflatable articles is higher than external pressure, the gas in the inflatable articles is discharged from the gap fast.

7. The self-inflating and bubble-discharging chamber support skeleton of claim 6, wherein the self-inflating and bubble-discharging chamber support skeleton further comprises a protective layer for wrapping the bubble support skeleton or the inflation chamber.

8. The self-inflating and bubble-discharging chamber support skeleton of claim 7, wherein the self-inflating and bubble-discharging chamber support skeleton further comprises a pressing chamber, and the pressing chamber is disposed at the first inflation port and the second inflation port for assisting inflation.

9. The self-inflating and deflating bubble supporting skeleton according to claim 8, wherein the pressing chamber and the self-inflating and deflating bubble supporting skeleton are of an integral structure.

10. The self-inflating and self-discharging bubble chamber support skeleton of claim 9, wherein the squeeze chamber and the self-inflating and self-discharging bubble chamber support skeleton are separable structures, and the squeeze chamber can be removed from the first inflation port of the bubble support skeleton and the second inflation port of the inflation chamber after inflation.
