The present invention discloses an automatic control element with uniformly-distributed stepping frequency, comprising a sprinkler and a fluidic element connected to the sprinkler, an outlet cover plate being secured onto an outlet of the fluidic element. A water inlet and a first air supply pore are formed symmetrically on the fluidic element, and a second air supply pore is formed on the water inlet. A water distributor is formed on the sprinkler, a water tank is provided on the outer side of the sprinkler, and the water distributor is in communication with an inner cavity of the water tank. A signal nozzle is provided on the wall of the water tank, and the signal nozzle is connected to the water inlet via a conduit. The additional arrangement of one water tank on the sprinkler overcomes the defect of use of air-water mixture only as signal water in the prior art, and solves the problems that a fluidic sprinkler head has a stepping frequency not so uniform and may fail to take signal water to complete the rotation action. |
