1) Fountain-nozzle is based on fluid dynamics technology related Laminar special design principle,with the special structure nozzle?the tap water transport by the pressurized water supply equipment to nozzle and then water burst forth as a bar fountain by nozzle,It can emerge even more impressive gesture, the spouting water body shape rules, crystal clear and clean flawless. If in the situation without external force , it can be relatively static stability in the state, and no uniform texture defects such as air bubbles, even will make people have the wrong impression, seems like a crystal rod or glass rod. If placed a special LED light source inside of the nozzle , light will be uniform conduction along the water wand to the end of water wand, the entire water column will luminescent at night, such as beautiful rainbow,With Wonderful statements. the light source transported by the flow water, seems like a light fiber, colorful and great pageantry; 2) If install a pneumatic or electric device into the Fountain-nozzle,it can be transformed leap water pattern?It can be arbitrarily spurt, also can be controlled by programme.The water column jumping from one place to another place,the incessant jumping water column add the dynamic feelings and vitality to the surrounding environment,At the same time it also add the endless fun to the tourists who playinging in the midst,That the water lines can be continuity flowing, as a crystal column, it also can be precise controlled by the electronic shutter and cut the water lines into sections will seems like the arbitrary jumping eidolons,uninterrupted and immaculate with no blemish. There are intervals among the jumping water lines,it can be continuous or intermittent,lines link into arc,the water column is single but high-radian,thin but brightness,clean as jade,beauty as rainbow.Multi-cooperation will create indescribable dulcet vision feast.
