Abstract:
A lamp showing movable floating ornaments, comprising a closed container, a liquid-guiding means, a driving means, and a lighting means;said driving means being located outside and below a lower part of said closed container, such that when an electromagnetic coil of said driving means is supplied with an electric current, a shaft mounted in said lower part of said closed container is electromagnetically induced to rotate, causing a propeller connected to said shaft to rotate at the same time;said lighting means being located outside and above an upper part of said closed container, such that light emitted by said lighting means is reflected from a reflecting mirror mounted above said lighting means to pass through a clear top surface of said closed container and down into said closed container;said closed container being provided near a middle area of said upper part with at least a transparent portion through which an interior of said closed container can be seen from outside of said closed container;said lower part of said closed container forming a stepped base of said closed container, said stepped base being further divided into an upper chamber, a middle chamber, and a lower chamber, diameters of said chambers sequentially reduce from said upper to said lower chambers; said shaft being received in said lower chamber with said propeller located in said middle chamber, and said liquid-guiding means being mounted in said upper chamber;said liquid-guiding means including an upper hollow cone, a middle hollow cone, and a lower disc; said lower disc being connected along a bottom outer periphery therof to a top inner periphery of said middle chamber in order to locate said lower disc above said propeller, said lower disc being formed at a vertical peripheral wall thereof with two diametrically opposite and transversely extended through holes, and above a bottom with two diametrically opposite and open-topped compartments, a radially outer side of each said compartment communicating with one of said two through holes and a radially inner side of each said compartment defining a vertical opening, portions on said bottom of said lower disc at two sides of said compartments being provided with two sector-shaped openings, said lower disc having a raised central portion to provide a central horizontal partition on said lower disc, a plate being uprightly fixed on a top of said central horizontal partition, so that when liquid passes through said lower disc said liquid is divided by said plate into two separated flows;said middle hollow cone being connected to a top of said lower disc and having a reduced open top, an expanded open bottom, and two horizontal walls radially inward extending from a lower outer periphery of said middle hollow cone and locating at positions immediately above said two compartments on said lower disc; andsaid upper hollow cone being a shallow cone having an expanded open top and a reduced closed bottom, said upper hollow cone being so dimensioned that an upper outer periphery thereof is fitly connected to an upper inner periphery of said upper chamber and a lower inner periphery of the upper hollow cone is fitly connected to an upper outer periphery of said middle hollow cone; said bottom of said upper hollow cone being provided with a plurality of vertically extended spray holes, and an inclined peripheral wall of the upper hollow cone between said open top and said closed bottom thereof being provided with a plurality of vertically extended through holes to serve as liquid inlets;whereby when said liquid in said closed container passes through said liquid inlets provided on said inclined peripheral wall of said upper hollow cone of said liquid-guiding means and enters into said upper chamber, said liquid is stopped by bottoms of said compartments on said lower disc and said horizontal walls of said middle hollow cone and could only pass said through holes on said vertical wall of said lower disc and flow down into said middle chamber via said vertical openings at said radially inner sides of said compartments of said lower disc; and when said driving means is actuated to induce said shaft and accordingly turn said propeller, said liquid in said closed container is initially sucked downward and then forced outward by said propeller; said liquid being forced outward by said propeller is stopped by a peripheral wall of said middle chamber as well as by said bottoms of said compartments and said central horizontal partition of said lower disc and could only move upward to pass through said sector-shaped openings on said lower disc to enter into said middle hollow cone; and when said liquid in said middle hollow cone flows to said bottom of said upper hollow cone connected to said top of said middle hollow cone, said liquid sprays upward into said upper part of said closed container via said spray holes on said bottom of said upper hollow cone at an increased speed, bringing said floating ornaments disposed in said upper part of said closed container to move around and create dynamic scenes in said closed container.
