1. A nozzle comprising:
a shell (10) comprising:
an axial channel (13) axially extending throughout the shell (10);
an internal face extending around the axial channel (13);
an annular chamber (14) extending around the axial channel (13);
lateral channels (15) for communicating the annular chamber (14) with the axial channel (13);
a splashing plate (30) connected to the shell (10) and formed with a conical aperture (31) in communication with the axial channel (13) and splashing apertures (32) in communication with the annular chamber (14);
a valve (40) being movable in the axial channel (13) and comprising:
a reduced section (411) formed at a first end;
an inlet (42) extending in a second end and operable for receiving a hose (H);
a first annular groove (431) extending around the reduced section (411);
a second annular groove (432);
a third annular groove (433) selectively in communication with the lateral channels (15);
a first ring (441) extending around the reduced section (411), wherein the first ring (441) is selectively in contact with the internal face of the shell (10);
a second ring (442) extending around the valve (40), wherein the second ring (442) is always in contact with the internal face of the shell (10);
a third ring (443) extending around the valve (40) on a side of the third annular groove (433), wherein the third ring (443) is always in contact with the internal face of the shell (10);
a fourth ring (444) extending around the valve (40) on another side of the third annular groove (433), wherein the fourth ring (444) is always in contact with the internal face of the shell (10);
a first group of outlets (451) for communicating the second annular groove (432) with the inlet (42);
a second group of outlets (452) for communicating the third annular groove (433) with the inlet (42);
a switch (20) comprising a portion pivotally connected to the shell (10) and another portion pivotally connected to the valve (40), wherein the switch (20) is operable to move the valve (40) along the axial channel (13);
wherein the axial channel (13) is in communication with the lateral channels (15) via the second annular groove (432) when the valve (40) is in a first position, thereby allowing water to be sprinkled from the splashing apertures (32);
wherein the first, second, third and fourth rings (441, 442, 443, 444) are all in contact with the internal face of the shell (10) when the valve (40) is in a second position, thereby closing the nozzle; and
wherein the second annular groove (432), the axial channel (13) and the conical aperture (31) are in communication with one another and the first ring (441) is not in contact with the internal face of the shell (10) when the valve (40) in a third position, thereby allowing water to go out of the conical aperture (31).
