A rich air sprayer of sanitary ware has a base, the base is disposed with at least two waterways; each waterway includes an inlet hole, a mutation cavity connected to the inlet hole and an air inlet hole connected to the mutation cavity, the flow area of the inlet hole is smaller than that of the mutation cavity, negative pressure is generated inside the mutation cavity when the water flows from the inlet hole into the mutation cavity, the negative pressure makes the mutation cavity suck air from the outside of the sprayer through the air inlet hole, the air and the water are mixed to form bubbles; the outlets of the mutation cavities intersect or the tangents of the outlets of the mutation cavities intersect, making the water flowing out of the outlets of the mutation cavities collide to enhance the granular sensation.
