Abstract:
1. A recirculating liquid advertising sign, comprising: a. a housing, the housing further comprising an annular front side and a slightly smaller in circumference rear side, so that the rear side fits inside the front side to give the advertising sign a finished look, the front side further comprising a hanging means to suspend the advertising sign from above, and a large opening through which the advertisement and recirculating liquid can be seen, the rear side further comprising an outer side, an inner side, and multiple heat radiating openings, the outer side comprising multiple holes for affixing the advertising sign to a wall, the housing's front side and the rear side further comprising a plurality of holes capable of allowing screws to fasten the front side and rear side together and multiple openings for controls for the advertising sign; b. a two-chambered insert capable of recirculating liquid, fixedly attached to the front side of the housing element, the insert comprising a transparent front chamber, capable of allowing the contents of the front chamber to be seen through the front of the housing, and a back chamber, wherein the volume of the back chamber is at least twice the volume of the front chamber, the back chamber further comprising an interior and exterior side, the insert further comprising an opaque dividing means between the front chamber and the back chamber, and an edge portion, the edge portion comprising a multitude of aligned holes capable of allowing screws to hold the chambers of the insert and the dividing means together, and a leak proof elastoplastic ring around the edge of the insert to prevent leaking; c. a lighting means comprising at least four CCFLs capable of illuminating the advertising logo and the recirculating liquid in the front chamber; d. a CCFL high voltage board fixedly attached to the exterior side of the back chamber and wired to the lighting means; e. an air pump fixedly attached to the inner side of the back side of the housing element; f. an air pipe extending from the air pump to a bubbling means fixedly attached to the bottom of the front chamber, the air pipe further comprising a unilateralism valve to prevent liquid from the front chamber from entering the air pipe; g. a suction pump fixedly attached to the exterior side of the back chamber with an oil pipe leading from bottom of the front chamber through the suction pump to the back chamber, the suction pump being capable of functioning at different rates and at different intervals, allowing for different liquid cycling times; h. a wet-pit pump fixed attached to the exterior side of the back chamber with an oil pipe leading from the bottom of the back chamber through the wet-pit pump to the front chamber, the wet-pit pump being capable of functioning at different rates and at different intervals, allowing for different liquid cycling times; i. a transformer fixedly attached to the inner side of the back side of the housing element; j. a control knob to adjust the cycling time of the suction pump fixedly attached to the inner side of the back side of the housing element; k. a control knob to adjust the flow of the air pump fixedly attached to the inner side of the back side of the housing element; l. a control board for the pumps, fixedly attached to the inner side of the back side of the housing element, the control board wired to the pumps, the control knobs and the transformer; m. a power switch for the lighting means fixedly attached to the inner side of the back side of the housing element which protrudes through an opening in the housing to allow the switch to be activated without disassembling the housing element; n. a power switch for the pumps fixedly attached to the inner side of the back side of the housing element which protrudes through an opening in the housing to allow the switch to be activated without disassembling the housing element; o. a switching power supply fixedly attached to the inner side of the back side of the housing element; p. an air-out control knob which extends from the exterior of the advertising sign, through holes in the front and back housing and into the front chamber of the insert; q. a transparent acrylic sign face with an printed or three-dimensional advertisement placed between the front side of the housing element and the front chamber of the insert, allowing consumers to see the advertisement and the recirculating liquid behind it through the opening in the front side of the housing element; r. electrical wiring to properly wire all electrical components to each other; s. an electrical supply to provide proper functioning of all electrical components; and t. a liquid with appropriate color and density to mimic the liquid being advertised and appropriate viscosity to allow for pumping through the two chambers by the wet-pit pump and the suction pump.
