NOZZLE HOLE MECHANISM

WIPO Patent Application WO/2011/158881

A1

A nozzle hole mechanism (10) is provided with a nozzle hole (28) which ejects a raw liquid into the atmosphere, a swirl chamber (30) which supplies the raw liquid to the nozzle hole (28), and a path (27) which supplies the raw liquid to the swirl chamber (30), and the swirl chamber (30) and the nozzle hole (28) are located on the same axis. The swirl chamber (30) is configured so that a solid cylindrical front section (30b), which communicates with the nozzle hole, and an annular rear section (30a) are coaxially arranged. The nozzle hole mechanism is configured in such a manner that the raw liquid is supplied to the rear section (30a) and discharged from the nozzle hole (28) via the front section (30b) or, alternatively, in such a manner that the diameter of the nozzle hole (28) is 0.2 mm or less and the length of the nozzle hole (28) is in the range of 0.05-0.3 mm. The configuration enables the nozzle mechanism to spray fine particles over a wide area using a small spray amount.
