1. The utility model provides a provide play water unit of anion raindrop form splash which characterized in that:

  • the water outlet unit comprises a water outlet unit main body, a flow channel, a water flow inlet and a water flow outlet which are arranged at the two ends of the flow channel, the cross section of the water flow inlet is smaller than that of the water flow outlet, and the length of a flow passage formed from the water flow inlet to the water flow outlet is less than the radial dimension of the cross section of the water flow outlet, and the flow passage is combined into a reverse venturi tube, when water flows through the water flow, a reverse Venturi effect is formed to generate negative pressure to suck air around the water flow to the water flow outlet, the water flow collides with the water flow so as to cut the continuously sprayed water flow into water drops, water flowers with the effect similar to that of raindrops in the nature are formed, meanwhile, as the cross section of the water flow inlet is smaller than that of the water flow outlet, the water flow and the water flow inlet generate high-speed friction, the kinetic energy generated by the friction is further superposed with the kinetic energy generated by the high-speed friction of the air and the water at the water flow outlet, and the Raynaud effect is generated.
