When the cup body 1 is inflated, the inflation valve core 33 is driven by external force to move downwards against the elastic force of the inflation spring 43 to open a control port (not shown) of the inflation valve cavity 203, so that the inflation is completed, and the interior of the cup body 1 is in a high-pressure state. After the inflation is completed, the inflation spring 43 resets the inflation valve core 33 to close the control port of the safety valve chamber 202.

When needing to pour out the aerated liquid, along the rotatory enclosing cover 5 of circumference, the inner cup 2 is temporarily unable to follow the synchronous circumferential direction of enclosing cover 5 because of the inside high pressure of cup body 1, make and produce relative rotation between enclosing cover 5 and the inner cup 2, thereby it slides to drive guide block 51 in guide way 212, and simultaneously, moving member 6 is downstream under the mating action of first helicitic texture and limit structure, make thimble 63 on the moving member 6 push down pressure release case 31, thereby make pressure release case 31 open the control mouth (see fig. 6) of pressure release valve pocket 201, realize the inside pressure release of cup body 1, thereby make the inflatable cup open more easily, and the security of use is higher. When the moving member 6 moves downwards to abut against the inner cap 2 to reach the lowest position of the moving member 6, the outer cap 5 continues to rotate along the circumferential direction, and at this time, the moving member 6 does not move downwards relative to the inner cap 2 but rotates synchronously with the outer cap 5 along with the inner cap 2 (not shown in the figure), so that the detachable connection of the inner cap 2 and the cup body 1 is realized, and the cup mouth is opened.

During the inflation or use process, once the air pressure inside the cup body 1 is too high, the air pressure drives the safety valve core 32 to move upwards (not shown in the figure) against the elastic force of the safety spring 42, so as to open the control port of the safety valve cavity 202, release the pressure inside the cup body 1, and improve the safety performance of the inflatable cup.
