The present disclosure claims priority to Chinese Patent Application No. 202120357748.2, filed on Feb. 7, 2021, which is incorporated herein by reference.
The present disclosure relates to a water outlet mechanism, in particular to a rotary water outlet mechanism and a washing device containing the same.
Generally, existing flushing devices obtain different flushing structures by changing the structure of the water body. For example, CN212405354U discloses a multifunctional bubbler, which includes a water inlet connector and a water outlet assembly rotatably connected to the water inlet connector, and the bottom of the water inlet connector is provided with water outlet holes. The end surface of the water outlet assembly is provided with a bubble water inlet hole and a blade water inlet hole. The inside the water outlet assembly is formed with a bubble water channel communicated with the bubble water inlet hole and a blade water channel communicated with the blade water inlet hole. The bottom of the water outlet assembly is formed with a bubble water nozzle and a blade water nozzle communicated with the blade water channel. The utility model can enable the bubble water inlet hole or the blade water inlet hole selectively to be connected to the outlet hole of the water inlet joint by rotating the water outlet assembly, thereby generating bubble water at the bubble water nozzle or generating a larger washing area at the blade water nozzle, such that the function of the bubbler can be diversified and the scope of application of the bubbler can be improved. Users can specifically choose to use bubble water or blade water for washing according to the washing items.
However, for strong stains, only the blade water can only be used to rinse at a certain angle, and the operator needs to hold the multifunctional bubbler and change the direction to change the rinse angle of the blade water. The existing flushing device cannot perform full flushing well in a fixed installation state.
In view of the above problems, the present disclosure provides a rotary water outlet mechanism and a flushing device, which adopts a housing with a gradually changing curved surface to restrict the water flow to change the original direction. The water flows through the oblique through hole of the water separator, the impeller is impacted to rotate, thereby driving the water guide to rotate to generate a rotating water flow. Compared with the non-rotating water flow, the cleaning intensity is improved and the cleaning time is saved. Preferably, the present disclosure adopts blade water as the outlet water stream, so as to have the best flushing effect.
In order to solve the technical problem, the present disclosure adopts the following solutions:
