Coanda effect: the coanda effect is also known as coanda effect, or coanda effect, i.e., the tendency of a fluid (water or air flow) to flow away from the original direction of flow, instead with a convex object surface, in other words, when there is surface friction between the fluid and the object surface over which it flows, the fluid will flow along the object surface as long as the curvature is not large.

It should be noted that, the structure of the flow guiding structure 122 is not specifically limited in this application, and any one of the following embodiments may be adopted:

embodiment one: as shown in fig. 3 to 5, the flow guiding structure 122 includes a central flow guiding column 1221 and a plurality of flow guiding ribs 1222 protruding from the central flow guiding column 1221 and disposed at intervals, the flow guiding structure 122 is connected with the inner wall of the water outlet section 12 through the flow guiding ribs 1222, the outer end surface of the flow guiding rib 1222 facing away from the central flow guiding column 1221 forms a flow guiding slope 1223, and a gap is formed between the flow guiding slope 1223 and the inner wall of the water outlet section 12.
