Abstract
An air valve connection head is compatible with a variety of air pumps and is formed of a first housing member and a second housing member. The first housing member is provided at one end thereof with an insertion hole in which the second housing member is lodged, and at other end thereof with a connection hole engageable with a cylindrical tube of the air pumps. The first housing member is further provided with a first air duct in communication with the connection hole and the insertion hole. The second housing member is provided with a receiving cell which is in turn provided at one end with a fitting port for receiving the air valve of an inflatable object. The receiving cell is provided at other end with a control handle pivoted thereto. The receiving cell is provided with an air injecting mechanism which is controlled by the control handle to lash securely and open up the air valve. The second housing member is provided in the outer periphery with a valve cell and a second air duct in communication with the valve cell and the receiving cell. The valve cell is provided with a check valve to allow one-way air flow from the first air duct to the second air duct.
