Ornament simulating dynamic scene of volcanic eruption

摘要

An ornament includes a closed showcase in which a liquid and a plurality of granules as well as a model of volcano are provided; a liquid-guiding mechanism provided in a lower part of the showcase to provide a cyclic liquid path for the ornament; and a driving mechanism located below the liquid-guiding mechanism to suck the liquid downward and then force the liquid upward via the liquid-guiding mechanism, so that the liquid carries the granules to repeatedly spout into a conduit in the model of volcano and erupt from a crater of the volcano and then scatter over the liquid-guiding mechanism, creating a dynamic scene similar to a volcanic eruption. A light and sound producing mechanism is mounted in a base of the showcase to produce flashes and sounds corresponding to the scene of volcanic eruption.
