The ventilation pipe is provided with a directed air jet port and an air supply source for supplying air to the ventilation pipe, and the plurality of water passage pipes are positioned on at least one spiral orbit having a vertical spiral axis. And a plurality of mist nozzles and the water pipe are housed in a vase-shaped container with an open upper end, regardless of atmospheric conditions, to constantly and stably represent the appearance of a tornado-shaped mist. Was achieved.

[0006]

According to the present invention, the mist group immediately after being ejected from the plurality of mist nozzles attached to the plurality of water passages having the curvature corresponding to a part of the spiral makes the spiral in the upward direction in the vase-shaped container. Multiple fog forms that are close to a part of. on the other hand,
In the vase-shaped container, air is ejected from the air ejection port of the ventilation pipe in the atomizing direction of the mist nozzle. The jetted air rises while spirally swirling along the inner surface of the wall of the pot-shaped container and is discharged from the upper end opening. Therefore, in the vase-shaped container, the ascending swirling air currents are mixed with each other in the process of mixing and flowing the mist in the shape close to the spiral, and the form of the tornado-shaped mist is expressed in the vase-shaped container. By configuring the vase-shaped container with a transparent material, the appearance of the tornado-shaped fog can be seen through from the side of the vase-shaped container, and by configuring the vase-shaped container with an opaque material, the appearance of the tornado-shaped fog can be seen. It is visible from the top opening.
