Title:
WATER DROPLET GENERATOR AND WATER DROPLET PROJECTOR
Document Type and Number:
Japanese Patent JP2020058969
Kind Code:
A
Abstract:
To provide a water droplet generator which can keep a size of each water droplet constant and freely change the time interval for water droplets to drop, and further, provide a water droplet projector which can project water crest of dropped droplet onto a floor or a ceiling by illumination.SOLUTION: A water droplet generator is so configured that a closed space is formed between a round transparent plate A and a round transparent plate with hole in the center, water is filled in the space, and water, which has been dropped and accumulated by a pipe F, is circulated by a tether pump E. Thus, water does not drop from a hole H and stops if the pump is not operated, and water in the hole H expands, turns into droplet and drops in such a manner that water is injected between A and B by the pump E. Further, a water droplet projection illuminator is configured in such a manner that water crest is projected onto a passage, a floor or a ceiling by an illumination LED light source in the water droplet generator.SELECTED DRAWING: Figure 1
