Vortex water flow accelerator

A vortex water flow accelerator comprises a connector pipe with a water inlet and a water outlet, a water outlet barrel connected to the water outlet end of the connector pipe and a plurality of spiral blades arranged in the water outlet barrel and connected with the connector pipe, the size of the water outlet is smaller than that of the water inlet, and an annular face and a first conical face are sequentially formed on the inner wall of the connector pipe in the direction from the water inlet to the water outlet. A second conical surface is formed on the outer wall of the joint pipe, a plurality of splitter plates which are uniformly distributed in the circumferential direction are formed on the second conical surface, the splitter plates protrude out of the water outlet end face of the joint pipe, the water outlet barrel is provided with a small-diameter end and a large-diameter end, the small-diameter end is connected to the splitter plates, and secondary water inlets are formed among the second conical
