Abstract
A rapid inflation and venting air valve of an airbed comprises at least one air inlet, a lower opening, cover openings, and, joint tubes; and a blower having a wind suction opening and a wind transfer tube. When the wind transfer tube is communicated with the air inlet and the joint tubes, air can be inflated into airbags. When the wind suction opening is communicated with the lower opening and the joint tubes, air can be vented out. Thereby, by only operating the rotary element, the functions of inflation and venting can be performed rapidly. As a result the object of emergency rescue is achieved. The air valve integrates the functions of inflation and venting in one unit by only one blower so as to simplify the structure and lower the cost.
