Claims10
A spray unit of a watering device, the spray unit comprising a mounting member and a housing for mutually confining a chamber, a rotor installed inside the chamber, the rotor being formed as a column and having a longitudinal axis, the rotor having a water inlet and a water outlet on two ends of the column, wherein:
- a water inlet side of the mounting member extends to a water outlet side of the housing in a direction aligned to a center axis of the chamber, the water outlet of the column being connected with thea water outlet side of the housing, and the longitudinal axis of the rotor is tilted relative to the center axis of the chamber;
- wherein either an inner annular wall of the water outlet side of the housing or the water outlet of the rotor is provided with at least one slot while the other one is provided with at least one guide member in a radial direction to be correspondingly matched to the at least one slot,
- wherein the matching of the at least one slot and the at least one guide member locates the water outlet of the rotor on the water outlet side of the housing, to enable the rotor to move along an interior surface of the chamber about the center axis of the chamber, but to prevent the rotor from self-rotating about the longitudinal axis of the rotor at the same time.
