AI Technical Summary
Technical Problem
Existing sprinkler designs suffer from elastic fatigue and irreversible deformation of components like elastic clips and plates, leading to unreliable operation and reduced service life due to long-term use.
Method used
A water flow switching device with a swing rod, elastic element, and stop element, where the stop element is movably inserted into a chamber, providing synchronous movement and enhanced coverage of water outlets, and a sprinkler design with a movable cylinder, connecting seat, gear sets, and impeller for reliable operation.
Benefits of technology
Improves switching accuracy, reliability, and extends the service life of the sprinkler by ensuring consistent elastic force, reducing wear, and preventing deformation under water pressure fluctuations.

Abstract
This invention relates to a water flow switching device for use in a sprinkler. The sprinkler includes a movable cylinder and a connecting seat, which are connected to each other to form an internal space. The connecting seat has a first water outlet and a second water outlet communicating with the internal space. The water flow switching device includes a swing rod, an elastic element, and a stop element. The swing rod is swayable between a first position and a second position and is disposed in the internal space. The swing rod includes a chamber that extends along an extension direction. The elastic element is telescopically disposed in the chamber along the extension direction. The stop element is connected to the elastic element to form a synchronous relationship and is movably inserted into the chamber along the extension direction. The stop element includes a first stop portion and a second stop portion. When the swing rod is in the first position, the first stop portion covers the first water outlet. When the swing rod is in the second position, the second stop portion covers the second water outlet.
