The present disclosure relates to a fountain device including: a fountain core and a floating portion. The fountain core includes a hydraulic portion and a power supply for providing power to the hydraulic portion and is configured to pump water from a water inlet at a lower portion by means of the hydraulic portion and spraying water via a water spout at an upper portion to form a fountain. The floating portion is configured to cause the fountain device to float in the water and forms a core mounting hole for holding the fountain core when inflated with a low density fluid, so that the fountain core can form a fountain by the hydraulic portion in a state that the fountain device floats in the water.

Embodiments provide an illuminated design in a liquid light wall. According to an embodiment, there is provided a liquid light wall including a front wall with a plurality of circular openings through which transparent pipettes may be inserted. The pipettes are filled with a colored liquid. The colored liquid can be edible. A light source shines light from behind the front wall, transferring the light through the pipettes, showcasing a design. The pipettes can be readily removed from the circular openings. Embodiments provide for a modular design of the liquid light wall such that multiple modules can be attached to one another.

The present invention relates to a decorative wreath with a miniature water fountain for household display and the process for making the same.

The present invention refers to a method for providing a liquid display displaying a selectable pattern (20-29, 45-48, 58-62) wherein a) either light rays (8, 79) emitted by a first emitter are characterized by at least one light parameter, with the light parameter being defined by a first light parameter defining the light rays (8, 79) as such, like the frequency and/or amplitude of the light, and/or by a second light parameter defining the emission of the light rays (8, 79), like the location, repetition rate, width and/or form of emission pulses of the light rays (8, 79), and light deflecting means (17-19, 39-43, 60-62, 82) emitted by a second emitter depend on the light parameter such that the emitted light deflecting means (17-19, 39-43, 60-62, 82) are tuned to the emitted light rays (8, 79) to create cinematographic light effects, b) or the light deflecting means (17-19, 39-43, 60-62, 82) emitted by the second emitter are characterized by at least one deflecting parameter, with the deflecting parameter being defined by a first deflecting parameter defining the characteristics of the deflecting means (17-19, 39-43, 60-62, 82) as such, like the material size, geometry, weight, amount, density, velocity, acceleration and/or kind of gas or solid material, and/or by a second deflecting parameter defining the emission of the deflecting means (17-19, 39-43, 60-62, 82), like the location, repetition rate, width and/or form of emission pulses of the light deflecting means (17-19, 39-43, 60-62), and the light rays (8, 79) emitter by the first emitter depending on the deflecting parameter such that the emitted light rays (8, 79) are tuned to the emitted light deflecting means (17-19, 39-43, 60-62) to create cinematographic light effects.

A hydromechanical display device includes a reservoir, a pump, an upper pressure chamber, a plug-in receptacle containing a plug-in variable pressure module, a control valve, and a lower channel, including a constant pressure compartment and a variable pressure compartment.

A light-emitting (LED) fountain light with a self-cleaning lens includes a light body with a central hole, a light housing surrounding the light body, a nozzle provided in the light housing and located in the central hole, a central hole pressing ring sleeved in the central hole, LED light beads arranged between the central hole pressing ring and the light housing and sealed by a sealant, a driving mechanism provided between the nozzle and the central hole pressing ring, a cleaning mechanism provided on a surface of the light body to scrape off algae and other dirt, and a transmission mechanism provided between the driving mechanism and the cleaning mechanism. In the LED fountain light, scrapers are rotated forward and backward once to effectively clean the algae and other dirt on the surface of the LED fountain light.

Plastic grid or framework arrangements are used to support and position of bowls that hold flower arrangements, candles, letters, and other decorative elements. These grids are deployable in water fountains, indoor and outdoor pools, and other small bodies of water during festive occasions or for longer term decorative display. The grid themselves do not float, and are positioned below the surface of the water, and thus are not readily visible. Buoyancy is provided at the hubs that form nodes in the grids. The hubs also support floating bowls containing various decorative elements. The resulting effect is that the various decorative elements appear to be floating on the surface while the sub-surface grid structure maintains their relative positioning, keeping the bowls from clumping together at the edges or in the corners of the pool or fountain.

A laminar water feature is provided which includes a housing having a deck niche, a niche collar, a spacer ring, and a lid, a laminar vessel having an inlet, an annular pocket, a vertical baffle, a horizontal baffle, a light pipe, a plurality of screens, a cap having an outlet, and threading within an isolated light chamber for removably accepting a lighting source, and a pivot adjustment bracket having a handle with push button assembly, ridge, and detent configuration for fixedly rotatably adjusting the angle of the laminar vessel.

A water display including a number of pixels or manifolds that may include water nozzles to emit streams of water and/or other utilities such as lighting is described. The water streams may be pixelated so as to provide a high resolution waveform or other choreography. The choreography transitions between waveforms to provide the appearance of a cascading or undulating wave. A tool to design the water display and simulate its appearance is also described.

A light-emitting (LED) fountain light with a self-cleaning lens includes a light body with a central hole, a light housing surrounding the light body, a nozzle provided in the light housing and located in the central hole, a central hole pressing ring sleeved in the central hole, LED light beads arranged between the central hole pressing ring and the light housing and sealed by a sealant, a driving mechanism provided between the nozzle and the central hole pressing ring, a cleaning mechanism provided on a surface of the light body to scrape off algae and other dirt, and a transmission mechanism provided between the driving mechanism and the cleaning mechanism. In the LED fountain light, scrapers are rotated forward and backward once to effectively clean the algae and other dirt on the surface of the LED fountain light.
