A fountain for both rainfall effect and/or waterfall effect. The fountain includes an inner pipe and an outer pipe. One end of both the inner pipe and the outer pipe is closed and another end is open. Each the inner pipe and the outer pipe has several holes made linearly along a length of inner pipe and the outer pipe. The outer pipe encases the inner pipe such that the holes in the inner pipe face upwards while the holes in the outer pipe face downwards when the fountain is horizontally aligned. The water supply is connected to the open end of the inner pipe.

The present invention relates a solar-powered, floating, fountain lamp, comprising a light-emitting elements, a fountain housing, and a solar panel, and the fountain housing acts not only as a three-dimensional lampshade for a first light-emitting portion, but also as a floating portion of the fountain lamp, and the fountain housing is substantially formed by a saucer-shaped cabin and a cylindrical lower part that are integratedly connected to each other, in which the saucer-shaped cabin located in an axially upper part of the fountain housing has an outer peripheral surface that is smooth and curved, and the plurality of light-emitting elements each project a light beam in a different direction, and the light-emitting elements projecting the light beams outward the fountain housing form point light sources at a top of the fountain lamp, the point light sources on the top act as a second light-emitting portion, and the light-emitting elements projecting the light beams inward the fountain housing form the first light-emitting portion, and the first light-emitting portion provides uniform lighting through the three-dimensional lampshade formed by outer walls of the saucer-shaped cabin and of the cylindrical lower part that are smoothly connected.

A pair of identical, specially-shaped, and specially-sized flow diverters is provided. In order to concentrate the flow of water passing over a waterfall, such as an ornamental backyard spa or swimming pool waterfall, a first flow diverter is attached adjacent a first sidewall of the waterfall structure, and a second flow diverter is attached adjacent a second sidewall of the waterfall structure. Water passing by the sidewalls is directed inwardly away from the sidewalls, thereby narrowing the flow of water over the fall and reducing overspray and reducing mineral build up and scale problems. In one novel aspect, an assemblage (a saleable product) includes a product container, the pair of flow diverters disposed in the container, a tube of silicone adhesive disposed in the container, and a set of printed usage instructions disposed in the container.

An above-ground swimming pool is provided. The pool includes a bottom surface with side walls extending upwardly therefrom to define an inner volume for receiving water. The pool further includes top edge portions mounted on a top perimeter of the side walls and caps mounted between adjacent top edge portions. The pool also includes at least one water module adapted to connect to and operate with the above-ground swimming pool. The water module has a module base connectable to the top perimeter of the side wall of the swimming pool, a module casing extending upward from the module base and having a distal opening; and a supply system provided within the module casing and having a discharge opening for supplying water out of the supply system and through the distal opening of the module casing to enter an inner volume of the above-ground swimming pool.

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 method for appreciating water balls using a water balls appreciation device, including a water balls discharge device and a light irradiation device, the method including: discharging the water balls, using the water balls discharge device, from tips of a plurality of nozzles, disposed at predetermined intervals in the lateral direction, by applying vibration to flowing water, the discharged water balls falling downwardly and in substantially a vertical plane; irradiating the water balls, using a light irradiation device, with light, the light irradiation device comprising a high-speed projector having a refresh rate of 300 Hz or more; and projecting a continuous screen of the projector in the water balls in the vertical plane regarded as a virtual screen by properly using a frame displaying a screen or an image and a frame not displaying a screen, so that a blinking duty is 20% or less, whereby the water balls are visually appreciated in the projected area. Then, by changing the timing of light emission for passing light through the image, it is possible to appreciate the movement of the water balls that changes in various manners.

Disclosed is two-tier fountain with a continuous scupper. A continuous scupper is a 360-degree, unrestricted border (i.e., continuous), scupper in an upper basin that creates an inward flowing laminar sheet of fluid. A continuous scupper maintains a laminar flow for great distances so that the fluid falls in a circular cascade sheet. On reaching the lower basin, the fluid creates a limited amount of turbulence during entry and therefore a reduced splash. The continuous scupper may be circular, or may have simple to complex variations that create different forms of circular cascade sheets. The upper basin may be open to the atmosphere, or may be closed to create even more spectacular circular cascade sheets.

A water display is described including a wall or other structure upon which streams of water are shot. The direction, velocity, pressure and flow rate of the water streams may be varied to provide entertaining visual effects, which may also be choreographed with music, lighting or other features.

An ornamental liquid display utilizing a silicone oil as the circulating fluid. A circulator moves the fluid such that it interacts with an effect surface, creating sensory interest. The fluid may be supplemented with various dyes, fragrances, and particles, and the implementation of the display may create visual and/or auditory interests by the motion of the fluid. The display may additionally use a purifier or filter to remove outside contaminants from the fluid.

A self-cleaning fountain includes: a structure having two ends, defining a first flow way for a first fluid to flow along, wherein the structure defines holes for allowing a second fluid to flow through the holes; a pump system configured to pump the first fluid to a first end of the structure; a distributer located at the first end of the structure and configured to spray the first fluid received from the pump system onto the structure; a catch basin located at a second end of the structure for collecting the first fluid that has moved along the flow way to the catch basin; a photocatalytic coating on the structure; and a light source configured to direct light on the photocatalytic coating.
