[0014] Fig. 3 is a diagram showing lid portion 16 of sprinkler nozzle 10 according to an embodiment of the present invention. Fig. 3(a) is a cross-sectional view (cross-sectional view along line AA) of the side of lid portion 16 of sprinkler nozzle 10, Fig. 3(b) is a front view of lid portion 16 of sprinkler nozzle 10, and Fig. 3(c) is a cross-sectional view of the sprinkler holes in lid portion 16 of sprinkler nozzle 10.

[0015] The watering nozzle 10 is a nozzle for suitably diffusing water to be sprayed on plants such as vegetables, fruit trees, garden trees, flowers, etc. The watering nozzle 10 includes a main body portion 12, a pipe portion 14, and a cover portion 16.

[0016] The main body 12 has a generally truncated cone shape with an internal space, has a top side with a small diameter and a bottom side with a larger diameter than the top side, and penetrates from the top side to the bottom side. In the main body 12, the diameter of the opening on the top side is set to, for example, 25 mm, and the diameter of the opening on the bottom side is, for example, 82 mm. In the main body 12, the length between the top and bottom sides is 97.56 mm.

[0017] The main body 12 will be described as being made of a material having an appropriate strength, such as an aluminum alloy containing aluminum, magnesium, and silicon, but it may of course be made of other materials.

[0018] 2(a), the opening 12a on the top surface side has a substantially spherical shape that fits the spherical connecting portion 14a of the pipe portion 14. The outer shape of the opening 12a having the substantially spherical shape is set to R10.

[0019] As shown in FIG. 2(a), the opening 12a widens in a tapered shape from the end thereof, and then has a connection portion 12b on the bottom side which is bent so as to be parallel to the center line of the approximately truncated cone shape of the main body 12 and is adapted to screw into the lid 16.

[0020] This connection part 12b is formed with a screw part for screwing into the lid part 16. Fig. 2(b) shows the main body part 12 as viewed from the front side, and the outline of the opening part 12a is visible near the center of the opening on the bottom side with a larger diameter, and the opening part 12a can be seen in the center.

[0021] The pipe section 14 is a cylindrical member having a connecting section 14a on one side that can be connected to the top surface side of the main body section 12, and a connecting section 14b on the other side that can be connected to a hose through which water flows. The diameter of the opening of the connecting section 14a of the pipe section 14 can be set to, for example, 25 mm, and the diameter of the opening of the connecting section 14b of the pipe section 14 can be set to, for example, 15 mm. The length of the pipe section 14 can be set to, for example, 130 mm.

[0022] The pipe portion 14 will be described as being made of a material having an appropriate strength, for example, an aluminum alloy containing aluminum, magnesium, and silicon, but it may of course be made of other materials.

[0023] The lid 16 can be attached to the bottom side of the main body 12, and is a lid formed with a plurality of water spray holes 16c for discharging water that has flowed into the main body 12 via the pipe 14. As shown in Fig. 3(a), a curved surface portion 16b is provided inside the cylindrical member 16a.

[0024] Furthermore, in an area of ​​the cylindrical member 16a where the curved surface portion 16b is not arranged, a screw portion for screwing with the connection portion 12b of the main body portion 12 is formed.

[0025] As shown in Fig. 3(b), the curved surface portion 16b has a plurality of water spray holes 16c formed therein. Fig. 3(c) is a cutaway view of the cover portion 16 so that the cross-section of the water spray holes 16c can be seen, and the cross-sectional shape of the plurality of water spray holes 16c is formed so that the opening area of ​​the water discharge side 16e is larger than that of the water inflow side 16d.

[0026] Here, the diameter of the water spray hole 16c is set to 0.3 mm, and the discharge side 16e has a gradually expanding truncated cone shape (the expanding angle is 60 degrees).

[0027] 3(a), lid portion 16 has a curved surface such that curved surface portion 16b, in which multiple water spray holes 16c are formed, protrudes in the direction of water spray. Lid portion 16 is provided with cylindrical member 16a having an annular wall portion that protrudes beyond curved surface portion 16b to protect curved surface portion 16b.

[0028] The diameter of the cylindrical member 16a is set to 82 mm, and the width of the annular wall portion is set to 20 mm. The curved portion 16b is described as being curved to have a radius of 167, for example, but this can be changed as appropriate.

[0029] Here, the connecting portion 14a of the pipe portion 14 has a spherical shape, and the top surface side of the main body portion 12 has a shape corresponding to the sphere, and the pipe portion 14 and the main body portion 12 are connected to each other by the connecting portion 14a at a predetermined angle. Here, the predetermined angle is described as being set to 45 degrees, but it can be changed as appropriate.

[0030] Although the connecting portion 14a of the pipe portion 14 and the top surface side of the main body portion 12 may be connected with a connecting member such as a bolt, the following description will be given assuming that the connecting portion 14a is fixed by welding after being set at a predetermined angle.

[0031] Next, a description will be given of the operation of the watering nozzle 10 configured as described above. A user who wishes to diffuse and sprinkle water on plants such as vegetables, fruit trees, garden trees, and flowers connects a hose that supplies water to the connection portion 14b of the pipe portion 14 of the watering nozzle 10.

[0032] Thereafter, when a faucet or the like is operated to allow water to flow through the hose, the water flows through the hose, in the pipe portion 14, and into the main body portion 12. The water that has flowed into the main body portion 12 is then discharged from the spray holes 16c in the curved portion 16b of the lid portion 16 and sprayed.

[0033] At this time, since the water spray hole 16c has a truncated cone shape that gradually widens toward the discharge side 16e, there is a remarkable effect that the water can be suitably diffused.

[0034] In addition, since the amount of protrusion of curved surface portion 16b is smaller than the amount of protrusion of the wall portion of cylindrical member 16a, there is an advantage that curved surface portion 16b can be protected even if sprinkler nozzle 10 is dropped.

[0035] Furthermore, water is not only clean tap water, but also agricultural water, which may contain dust and the like. When such water is sprayed, there is a problem that the watering hole 16c becomes clogged and the force of the watering weakens. When this problem occurs, the hose is removed from the watering nozzle 10, and the tip of the hose that discharges the water is positioned so that it faces the surface side of the curved surface portion 16b, i.e., the discharge side 16e of the watering hole 16.

[0036] When water is poured in this state, the wall of cylindrical member 16a guides the water toward curved surface 16b, so that the water flows in from outlet side 16e of sprinkler hole 16c and flows out from inlet side 16d. This blows away dust blocking sprinkler hole 16c, and clears blockage of sprinkler hole 16c.

[0037] Furthermore, according to the watering nozzle 10, the connecting portion 14a of the pipe portion 14 is spherical, and the top surface side of the main body portion 12 has a shape corresponding to the sphere, which has the advantage that the pipe portion 14 and the main body portion 12 can be fixed at the desired angle using the connecting portion 14a.

[0038] Next, we will explain watering nozzle 20, which is a modified example of watering nozzle 10. Figure 4 is a side view of watering nozzle 20. The only differences between watering nozzle 20 and watering nozzle 10 are the shape and size, and the rest are the same, so the following explanation will focus on the differences.

[0039] The watering nozzle 20 comprises a main body 22, a pipe 24, and a lid 26. The main body 22 has a generally truncated cone shape with an internal space, has a top side with a smaller diameter and a bottom side with a larger diameter than the top side, and penetrates from the top side to the bottom side. In the main body 22, the diameter of the opening on the top side is set to, for example, 23 mm, and the diameter of the opening on the bottom side is, for example, 57 mm. The length between the top and bottom sides of the main body 22 is 97.56 mm.

[0040] The pipe section 24 is a cylindrical member having a connecting section 24a on one side that can be connected to the top surface side of the main body section, and a connecting section 24b on the other side that can be connected to a hose through which water flows. The diameter of the opening of the connecting section 24a of the pipe section 24 can be set to, for example, 25 mm, and the diameter of the opening of the connecting section 14b of the pipe section 14 can be set to, for example, 15 mm. The length of the pipe section 24 can be set to, for example, 280 mm.

[0041] As shown in Fig. 4, the lid 26 has a curved surface such that the curved surface portion 26b, in which a plurality of water spray holes 26c are formed, protrudes in the water spray direction. The lid 26 is provided with a cylindrical member 26a having an annular wall portion that protrudes beyond the curved surface portion 26b so as to protect the curved surface portion 26b. The diameter of the cylindrical member 26a is set to 62 mm, and the width of the annular wall portion is set to 12 mm. The curved surface portion 26b will be described as being curved to have a curved surface of R109, for example, but this can be changed as appropriate.

[0042] As described above, although the shape and size of the watering nozzle 20 are different from those of the watering nozzle 10, the structure itself is the same, and therefore the watering nozzle 20 exerts the same effects as the watering nozzle 10. [Explanation of symbols]
