PURPOSE: To provide a mist generating system, which can be connected to a hot water or cold water supply valve built in an existing bath room without needing a large- scaled construction by mounting a multiplicity of collision plates arranged like backswept wings in the impeller revolving direction while holding certain intervals both in the radial direction of the impeller and in the circumferential direction of the impeller, and is easy in structure.

CONSTITUTION: When a motor A is revolved, hot water flows through a hot water or cold water supply valve, a branch pipe 14, and the opening 9a formed on an apical plate 9a of a second storage member 9 of a mist generating apparatus A to be supplied for the center opening 3d of a revolving impeller 3. Hot water flows into a channel either between a base plate 3a and an annulus ring plate 3c or in the annulus ring plate 3c and flows while being accelerated in the tangential direction from the revolving base plate 3a and the annulus ring plate 3c. The liquid film of the hot water reaches the periphery of the impeller 3, and is atomized by centrifugal force, and then jets in the tangential direction. The jetted hot water mist is more micrified by colliding against the rear surfaces of collision plates 6 arranged at certain intervals in the radial direction and the circumferential direction of the outside of the impeller 3. The micrified mist passes through a first lid member 7 and is jetted upward.
