Abstract: A rotary water outlet mechanism and a flushing device, including a housing having a gradually changing curved surface and a water outlet part connected to one end of the housing. A water separator provided with at least one oblique through hole, an impeller and a water guide are provided in sequence in a water flow direction between the housing and the water outlet part. The impeller is in transmission connection with the water guide rotatably connected with the water outlet part, one end of the water guide is provided with a water outlet. The water flow enters the housing, and under a guidance of the gradually changing curved surface of the housing, the water flow passes through the oblique through hole, and flows through the impeller and drives the impeller to rotate, such that the water guide rotates to generate a rotating water flow.

Abstract: The present invention discloses a rotary cup washing device, comprising a flushing nozzle, a rotary impeller, a swirl outflow member, a fixed head and a water inlet pipe. The flushing nozzle, the rotary impeller, and the swirl outflow member are all provided in the fixed head. The flushing nozzle is connected to an upper part of the rotary impeller, and a lower part of the rotary impeller is correspondingly matched with the swirl outflow member, the flushing nozzle and the rotary impeller are capable for rotating relative to the fixed head under a water discharge action of the swirl outflow member. A lower part of the fixed head is connected to the water inlet pipe, and the water inlet pipe is connected to a pressure source. The present invention is capable of rotating the water to wash the cup in an omnibearing and uniform manner, and the cleaning effect is better.
