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.

Abstract: An adjustable air supply valve of an air cushion bed is disclosed, the air supply valve has an air supply valve installed between a first tube and a second tube. The air supply valve comprises a round seat, an air valve, a cover plate, a locking plate and a driving element. It has the operation modes of full opening for supplying air, half opening for supplying air, full closing and venting. Therefore, it can be operated to met the requied condition. Especially, if the air cushion bed is designed to have a plurality of different sections which can be adjusted based on different parts of the human body. The adjustable air supply valve has the effect of independently supplying air to the different sections.

Abstract: A multiple tubes combination structure for being assembled with air tubes of an airbed is disclosed, wherein a plurality of tubes are assembled in a combinational structure. Each individual component of the combinational structure has a specific element having a predetermined configuration. Thereby, when it is desired to assemble the combinational structure, it is only necessary to assure the configurations of elements. No error occurs. Thereby, the multiple tubes combination structure has a beautiful outlook.
