Abstract

An outlet device providing fan-shaped pulsating water particles includes a water inlet portion that has at least two inlet holes that are uniformly rotatably symmetrically arranged; and an outlet portion having a single outlet hole such that a vertical projection of the single outlet hole onto a horizontal plane of the water inlet portion partially coincides with one inlet hole of the at least two inlet holes and forms a flow down area and water vertically flows from an overlapping portion of the one inlet hole to a coinciding overlapped portion of the single outlet hole without changing flow direction as flow down water while water tangentially flowing from the one inlet hole toward a non-coinciding portion of the single outlet hole rotates as rotating water and impacts the flow down water to form water particles. A shower head including the outlet device is additionally provided.

First claim

The invention claimed is:

1. An outlet device providing fan-shaped pulsating water particles, comprising:
a water inlet portion that comprises at least two inlet holes that are evenly rotatably symmetrically arranged; and
an outlet portion having a single outlet hole such that a vertical projection of the single outlet hole onto a horizontal plane of the water inlet portion partially coincides with one inlet hole of the at least two inlet holes and forms a flow down area and water vertically flows from an overlapping portion of the one inlet hole to a coinciding overlapped portion of the single outlet hole without changing flow direction as flow down water while water tangentially flowing from the one inlet hole toward a non-coinciding portion of the single outlet hole rotates as rotating water and impacts the flow down water to form water particles,
wherein the water inlet portion is annular to provide an annular inlet portion,
wherein the outlet device further comprises a rib disposed along a diameter direction of the annular inlet portion that divides the annular inlet portion into the two inlet holes, and
wherein a vertical projection of an edge of the single outlet hole on a horizontal plane of the water inlet portion intersects with an edge of the rib to commonly surround the flow down area.

2. The outlet device according to claim 1 , wherein the rib has a cross-section that is a rectangle, that is tri-forked, or that is cross-shaped.

3. A shower head providing a fan-shaped pulsating water spray, comprising:
a main body provided with an accommodating chamber having a bottom portion in which is defined a plurality of outlet holes; and
an outlet body disposed in the accommodating chamber and having a bottom surface disposed with a water inlet portion,
wherein the water inlet portion comprises at least two inlet holes uniformly rotatably symmetrically arranged such that a vertical projection of each respective outlet hole of the plurality of outlet holes onto a horizontal plane of the water inlet portion partially coincides with a respective one inlet hole of the at least two inlet holes and forms a flow down area and water vertically flows from an overlapping portion of the respective one inlet hole to a coinciding overlapping portion of each respective outlet hole without changing flow direction as flow down water while water tangentially flowing from the respective one inlet hole toward a non-coinciding portion of each respective outlet hole rotates as rotating water and impacts the flow down water to form water particles,
wherein the water inlet portion is annular to provide an annular inlet portion,
wherein the shower head further comprises a rib disposed along a diameter direction of the annular inlet portion that divides the annular inlet portion into the two inlet holes, and
wherein a vertical projection of an edge of each respective outlet hole on a horizontal plane of the annular inlet portion intersects with an edge of the rib to commonly surround the flow down area.

4. The shower head according to claim 3 , wherein the rib has a cross-section that is a rectangle, that is tri-forked, or that is cross-shaped.
