Abstract

A spray unit of a watering device is equipped with a structure of rotor nozzle, the spray unit is composed of a mounting member and a housing for defining a chamber, a rotor deployed inside the chamber; wherein, at least one stopper set on the inner side of the chamber near the water outlet side is correspondingly matched to multiple guide members on one end of the water outlet of the rotor, and it can be employable to the handy watering device.

First claim

What is claimed is:

1. 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.

2. The spray unit as in claim 1 , wherein a flow director is deployed between the housing and the mounting member, the flow director being provided with at least one guide vane and a position rod aligned to the center axis of the chamber.

3. The spray unit as in claim 2 , wherein the flow director has an annular base located on the mounting member 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 has an inner wall equipped with at least one current blade.

7. The spray unit as in claim 1 , wherein the water outlet of the rotor is a spherical end forming a complementary mechanism to the water outlet side of the housing.

8. The spray unit as in claim 1 , wherein the at least one slot is provided on an outer annular surface of the water outlet of the rotor, and the at least one guide member is protruding from the inner annular wall of the water outlet side of the housing.

9. The spray unit as in claim 1 , wherein the inner annular wall of the water outlet side of the housing is provided with the at least one slot, wherein the at least one guide member is at least one stop rod protruding radially on the water outlet of the rotor.

10. The spray unit as in claim 1 , wherein the housing has at least one stopper being provided with a bevel.
