| description | The utility model aims to provide a balloon inflating structure which is simple and reliable in structure and good in air tightness. The balloon inflating structure comprises an inflating pipe, a counter bore part is arranged in a pipe opening of the inflation pipe. A movable valve core made of a soft material is arranged in the counter bore part; a conical surface is arranged on the peripheral wall of the movable valve element, the conical surface is in sealing fit with the lower opening of the counter bore part, a valve element limiting seat is arranged at the upper opening of the counter bore part, a hollow vent hole is formed in the valve element limiting seat, a vent hole is formed in the lower end of the valve element limiting seat, and the vent hole is communicated with the hollow vent hole. Compared with an existing automatic sealing device made of a PE film, inflation pressure does not need to be controlled, air tightness is good, long-time air tightness of the balloon can bemaintained, air tightness |
