<p>PROBLEM TO BE SOLVED: To stably and successively provide a negative ion atmosphere forming apparatus, capable of producing negative ion atmosphere inside a specific region. SOLUTION: A rotating cup body 30 is connected to a pneumatic driven motor 10 for operation and the air flow is fed to the rotary cup body from a compressor 21 via a hollow driving shaft 12, piercing through the pneumatic driven motor 10. The negative electrostatic potential is applied to a housing 11 of the motor 10 and the driving shaft 12 by a negative ion generating circuit 23, and the air, flow running in the driving shaft 12, is ionized negatively. The rotating cup body 30 converts the negatively ionized air flow into shaping air (curtain air flow) swirling nearly in conical shape, and the negative ion atmosphere is formed in a specified region inside the shaping air. At the same time, a functional liquid from a function liquid source 24 is vaporized with the centrifugal force, etc., to be spreaded in the specified region.</p> |
