本发明公开了一种可切换出水水花的自清洁起泡器，包括起泡器壳体，起泡器壳体的内部为上下连通的腔体，腔体的上部设有进水口，腔体的下部设有出水口，腔体的内壁中部设有出水体和喷嘴，出水体顶端设有向外的第一导水面，且出水体中部设有由上至下贯穿整个出水体的通孔；喷嘴内圈设有向外的喷口为第二导水面；当第二导水面高于第一导水面时，水流受到第一导水面的约束，水流喷射进入出水体的非内侧腔体后喷射而出；当第一导水面高于第二导水面时，水流受到第二导水面的约束，水流喷射进入出水体的内侧腔体后喷射而出。通过出水体与喷嘴的相对位移，来控制喷嘴的出水射流方向，从而达到一个起泡器便可实现改变出水水花的效果。

The invention discloses a self-cleaning bubbler capable of switching water spray of outlet water. The self-cleaning bubbler comprises a bubbler shell, wherein a cavity communicating from top to bottomis formed in the bubbler shell, a water inlet is formed in the upper portion of the cavity, and a water outlet is formed in the lower portion of the cavity; a water outlet body and a nozzle are arranged in the middle part of the inner wall of the cavity, an outward first water guide face is arranged at the top end of the water outlet body, a through hole penetrating through the whole water outletbody from top to bottom is formed in the middle part of the water outlet body, and an outward nozzle opening formed in the inner ring of the nozzle is a second water guide face; when the second waterguide face is higher than the first water guide face, water flow is restrained by the first water guide face, and the water flow is jetted out after being jetted into a non-inner side cavity of the water outlet body; and when the first water guide face is higher than the second water guide face, the water flow is restrained by the second water guide face, and the water flow is jetted out after entering an inner side cavity of the water outlet body. And the water outlet jet direction of the nozzle is controlled through the relative displacement of the water outlet body and the nozzle so that the effect of changing the water spray of the outlet water can be achieved by one bubbler.
