ABSTRACT:
The present invention provides a bumping-type sprinkler. The sprinkler includes a main body, where an inlet pipe coupling end is mounted at the lower end, an upper frame is mounted at the upper end, and a water outlet is arranged at lower flange nearby the upper frame. A revolving member, arranged onto the upper frame of the main body, has a torsional spring and a revolving portion. An outflow turntable is assembled corresponding to the water outlet of the main body. A pivot portion is placed centrally on the outflow turntable for screwing it laterally on the water outlet at interval. A plurality of outflow guide holes are arranged at intervals along a circular path of the eccentric circumferential portion of the outflow turntable. The outflow guide holes can be located corresponding to the water outlet in line with the change of rotation/displacement angle of the outflow turntable.
