Abstract: A periodical mechanism of a sprinkler includes a casing and a wheel is received in the casing to introduce water into a chamber of the casing in which a gear set is received. The gear set includes multiple gears and is connected between the wheel and a rotatable member which has a plurality of openings and closed areas. The casing includes a cover which includes an outlet so as to introduce water into the sprinkler. The outlet includes multiple openings and closed areas so that when the wheel is rotated by water entering the casing, the gear set drives the rotatable member. The water periodically enters into the sprinkler when the respective openings of the rotatable member and the cover are in alignment with each other.
