ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to an air valve connection head of an inflation device, and more particularly to an air valve connection head of an inflation device which is provided with an air storage bottle.
BACKGROUND OF THE INVENTION
The conventional bicycle air pumps are used to inflate the bicycle tires by compressing and pumping air into the bicycle tires. There is a new inflation device which is designed to inflate the bicycle tire without the compressing and the pumping actions. The inflation device is provided with an air storage bottle in which the compressed air is stored for inflating the bicycle tire. Such an inflation device as described above is complicated in construction, especially the air valve connection head of the inflation device.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an inflation device with an air valve connection head which is simple in construction and can be easily used. The air valve connection head of the present invention is intended to be an integral part of the inflation device comprising an air storage bottle in which the compressed air is kept.
The present invention comprises a housing, a base block, a penetrating member, a valve member, an elastic member, an elastic annular block, a press member, and a handle. The housing has a receiving compartment, which is provided at one end thereof with an engagement port, and at other end thereof with a through hole. The housing further has an insertion hole perpendicular to the receiving compartment. The insertion hole is used to receive the nozzle of the air storage bottle. The penetrating member is disposed in the insertion hole for piercing the sealed opening of the nozzle of the air storage bottle. The valve member is movably disposed in the insertion hole and is provided with a protuberance facing the air hole of the housing. The valve member is pushed by the compressed air to remain at the innermost end of the insertion hole such that the protuberance obstructs the air hole. The elastic annular block is disposed in the receiving compartment and is provided with a through hole. The press member is movably disposed in the receiving compartment such that one end of the press member urges the annular block. The press member is provided with a cavity and at least one guide hole in communication with the cavity. The press member is provided in the periphery thereof with an inclined plane which pushes the valve member to move toward the insertion hole at the time when the press member is moved toward the annular block. The handle is fastened pivotally to the housing for forcing the press member to displace.
