Field of the Invention [0001] The present invention relates to a fluid ejection apparatus capable of adjusting a spray pattern, and more particularly, to a fluid ejection apparatus capable of controlling a spray pattern in which a fluid is ejected in different patterns as a rotation unit coupled to the main body rotates.

Generally, the fluid ejection apparatus is manufactured to have a hemispherical front surface and to spread the water over a wide area. However, since a plurality of water spray holes are formed on the hemispherical head surface, the manufacturing process becomes complicated.

In consideration of this, a plurality of water spray holes are drilled in the water spray plate of the flat plate so that water is sprinkled, and the outer circumference is formed with an inclined surface inwardly to form a water spreading area or an outwardly inclined surface, So as to simplify the production of a mold.

However, in the conventional fluid ejection apparatus, since the inner sloping surface or the outer sloping surface is selectively formed on the spraying plate, water can not be concentrated or diffused in one head, and only one function can be realized. There is a technical drawback.

FIG. 1 is a perspective view of a fluid ejection apparatus capable of adjusting a spray pattern according to an embodiment of the present invention.

Hereinafter, a fluid ejecting apparatus capable of adjusting a spray pattern according to an embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 1, a fluid spray device capable of adjusting a spray pattern according to an embodiment of the present invention may include a main body 100, a spray nozzle 200, and a rotation part 300.

The main body 100 is connected to a water supply device, and a flow path 110 through which the fluid supplied from the water supply device moves can be formed in the main body 100.

2 is a view illustrating a spray nozzle of a fluid spray device capable of adjusting a spray pattern according to an embodiment of the present invention.

2, the injection nozzle 200 may be formed in a flat plate shape, and may be divided into a plurality of injection areas forming a concentric circle with respect to the center of the injection nozzle 200. [ A plurality of fluid ejection holes may be arranged in different patterns in each ejection region.

A plurality of first fluid ejection groups 212 may be formed in at least one of the plurality of ejection regions. The first fluid ejection group 212 includes a plurality of first fluid ejection holes (not shown) disposed on a concentric circle centered on an arbitrary first reference point and refracting a stream in a direction toward a normal of the ejection nozzle 200 at a first reference point 212a.

The third fluid ejection group 232 is disposed on a circle centered on an arbitrary third reference point and has a third fluid ejection hole 232a for refracting the water stream in a direction toward the normal of the ejection nozzle 200 at the third reference point ). Here, the number of the third fluid injection holes 232a forming the third fluid injection group 232 may be smaller than the number of the first fluid injection holes 212a forming the first fluid injection group 212.

The first direction switching portion 212b may protrude inward toward the reference point of the first fluid ejection group 212 in the first fluid injection hole 212a. Therefore, the fluid passing through the first fluid injection hole 212a can form a water stream that is concentrated toward the opposite side of the first direction switching portion 212b and is refracted toward the normal direction of the reference point.

Thus, the water stream passing through the plurality of first fluid injection holes 212a can form one water stream at the normal line at the first reference point.

Therefore, by thickening one water stream, the flow rate becomes larger than that in the case where the fluid is injected in the fluid injection holes 212a, 222a and 232a in one direction, and the flow velocity is further increased, so that the fluid can be injected far.

The second fluid injection hole 222a may have a second direction switching part 222b protruding inward toward a direction opposite to the second reference point. Therefore, the fluid passing through the second fluid injection hole 222a is concentrated on the opposite side of the second direction switching portion 222b and forms a water stream which is refracted toward the direction opposite to the direction normal to the second reference point can do.

The water stream passing through the plurality of second fluid ejection holes 222a may be ejected so as to spread outwardly.

The shape of the third fluid injection hole 232a is the same as that of the first fluid injection hole 212a. If a plurality of first fluid ejection holes 212a constituting the first fluid ejection group 212 are disposed on a plurality of concentric circles, a plurality of third fluid ejection holes 232a constituting the third fluid ejection group 232 ) May be placed on a circle centered on the third reference point. The number of the third fluid injection holes 232a forming the third fluid injection group 232 is relatively larger than the number of the first fluid injection holes 212a forming one fluid injection group 212 Can be written down.

Accordingly, the water stream injected from one third fluid injection group 232 may have a smaller flow rate than the water stream injected from one first fluid injection group 212.

In this embodiment, the ejection region is divided into three ejection regions, that is, the first ejection region 210, the second ejection region 220, and the third ejection region 230.

The first ejection region 210 is located at the innermost side of the ejection nozzle 200 and the second ejection region 220 is enclosing the first ejection region 210 from the outside. And may be positioned at the outermost portion of the injection nozzle 200 in a form of enclosing the second injection region 220 from the outside.

A plurality of first fluid ejection groups 212 may be formed in the first ejection region 210 and a plurality of second fluid ejection groups 222 may be formed in the second ejection region 220. A plurality of third fluid ejection groups 232 may be formed in the third ejection region 230.

A plurality of first fluid ejection groups 212 having the fastest water flow rate are arranged in the first ejection region 210 located at the innermost side of the ejection nozzle 200 so that a strong water stream is concentrated at the center, You can get a feeling of being very strong.

A third fluid ejection group 232 having a slower flow rate than the first fluid ejection group 212 is disposed in the third ejection region 230 located at the outermost portion of the ejection nozzle 200, The effect of even massage can be expected.

A second fluid ejection group 222 is disposed in the second ejection region 220 disposed between the first ejection region 210 and the third ejection region 230 so as to spread the water stream outwardly, So that the user can feel the soft mist effect.
