Patent ID: 8186987

Claim:
A nano-fiber manufacturing apparatus having an ejection unit that ejects solution which is a raw material liquid for a nano-fiber, to a manufacturing space in which the nano-fiber is manufactured by an electrostatic explosion of the solution, and a charging unit that charges the solution, said nano-fiber manufacturing apparatus comprising: a gas supply source that supplies a safety gas to change an atmosphere of the manufacturing space, in which the solution is ejected, into a low oxygen atmosphere; a partition that maintains the manufacturing space at a lower oxygen atmosphere than an atmosphere of a space outside of said partition, wherein a space inside of said partition includes the manufacturing space, and wherein the space inside of said partition is not air-tightly separated from the space outside of said partition; a collecting unit configured to collect a manufactured nano-fiber; a first working chamber having the manufacturing space inside and formed with said partition, said first working chamber being capable of keeping a safety gas inside; a second working chamber connected to said first working chamber and formed with said partition, said second working chamber being capable of housing one of the ejection unit and said collecting unit; a first gate being capable of opening and closing between said first working chamber and said second working chamber; and a first door being capable of opening and closing between said second working chamber and an outside of said second working chamber.
