Pressurized air supplying mechanism, pressurizing device and extracting apparatus

摘要

In a main body of a pressurizing head (40), a plurality of air nozzles (41A) is arranged in a row. A nozzle head (81A) of each air nozzle is provided with an O-ring (86A). A lower end portion of the nozzle head has a diameter of φA which is approximately the same as a diameter φa of an extracting cartridge (2). The lower end portion can fit in an inner peripheral surface of the extracting cartridge, correctly positioning the air nozzle. At least one (41B) of the air nozzles arranged in predetermined positions is set lower than the others. Since the air nozzles in the predetermined positions firstly move away from the extracting cartridge, and the lowered air nozzle subsequently moves away after the pressurization operation. The air nozzles will be easily separated from the extracting cartridge.
