Structure of rotor nozzle and watering device

1. A spray unit of a watering device, the spray unit comprising a mounting member and a housing for mutually confining a chamber with one water inlet side and one water outlet side, a rotor installed inside the chamber, the rotor having a longitudinal axis, the rotor having a water inlet and a water outlet at two ends of the rotor respectively, and the water outlet being connected with the water outlet side, wherein:

the mounting member includes a position rod aligned to a center of the chamber, the position rod and the water outlet side define a center axis of the chamber, and the longitudinal axis of the rotor is tilted relative to the center axis of the chamber;

wherein, the water outlet of the rotor is a spherical end forming a complementary mechanism to the water outlet side in a direction of the longitudinal axis of the rotor;

wherein, an inner annular wall of the water outlet side of the housing is provided with at least one slot, the water outlet of the rotor being provided with at least one guide member in a radial direction of the rotor, the at least one slot and the at least one guide member are correspondingly matched in the radial direction of the rotor.

2. The spray unit as in claim 1 , wherein a flow director is deployed between the housing and the mounting member, and the flow director has at least one guide vane, the position rod is placed on the flow director.

3. The spray unit as in claim 2 , wherein the flow director has an annular base and a center base, the at least one guide vane connects to an inner wall of the annular base and an outer wall of the center base.

4. The spray unit as in claim 2 , wherein a rod body is extendedly set on the water inlet of the rotor for locating on an outer wall of the position rod extended from the flow director.

5. The spray unit as in claim 2 , wherein the flow director and a bottom of the mounting member are arranged in a partition formation.

6. The spray unit as in claim 1 , wherein the rotor forms a hollow column having one inner wall equipped with at least one current blade.

7. The spray unit as in claim 1 , wherein the at least one guide member is at least one stop rod being protruded on an annular surface of the rotor in the radial direction of the rotor.

8. The spray unit as in claim 7 , wherein the housing has at least one stopper having a bevel, the at least one stopper defines a boundary of the slot.

9. The spray unit as in claim 1 , wherein a number of the at least one first guide member is plural, a number of the at least one second guide member is corresponding to the number of the at least one first guide member.
