Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a means for spraying fine and soft water droplets, and more particularly to a sprinkler and a flower stand suitable for watering flowers and the like.

[0002]

2. Description of the Related Art In recent years, the so-called gardening, in which flowers are planted and enjoyed in flower beds, planters, pots, and the like, has become a boom. In order to water planted flowers regularly or as needed, watering is often performed by attaching a shower port to the end of a water hose. However, the water spouted from the shower port may be too powerful to damage the flowers, or the amount of water may be too large to cause root rot, or may get wet at any time. In addition, if a fountain with momentum falls directly on the ground, the soil may be dug and the roots may be exposed. Conversely, if the amount of water is relatively small so as to prevent scattering outside the planter when watering a square planter or the like, there is an inconvenience that water cannot be properly supplied to every corner of the planter.

[0003] As a means for solving such a problem, for example, a drip-type watering system and a seepage-type watering system are known. The drip-type watering system described above, connects a micro-tube to a water hose, attaches a drip nozzle for dropping water to the tip of the micro-tube, and hollowly deploys a drip nozzle near the root of a flower to be watered,
It is configured so that water is dropped from a dropping nozzle to water the flowers. On the other hand, the seepage type watering system arranges a porous water permeable tube connected to a water hose near the root of a flower to be watered, and oozes water from the peripheral surface of the water permeable tube to water the flower. It is constituted in.

[0004]

However, in the case of the drip type, the drip nozzle and the water guide tube must be individually guided to the vicinity of all the plants of the flower, and the piping structure of the water guide tube increases as the number of plants increases. It becomes complicated,
Installation costs increase. On the other hand, in the case of the exuding type, the water reaches only the vicinity of the water-permeable tube, and the exuded water evaporates immediately during the middle of summer, so that stable watering cannot be performed. In addition, in both the drip type and the exuding type, water from the drip nozzle and the water permeable tube does not fly out, so that even if water can be watered to the root, water cannot be directly sprayed on petals and leaves. Therefore, in order to wash out the dust and the like adhering to the surface of the petals and leaves to make it fresh, it is necessary to perform watering twice on the surfaces of the petals and leaves.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has a water-supply device and a flower stand which are inexpensive and can be directly sprinkled on flowers or the like with a small amount of water and without strong momentum. The purpose is to provide.

[0006]

In order to achieve the above object, a water sprinkler according to the present invention includes a water guide pipe into which pressurized water is introduced, and a fountain having a predetermined opening diameter for jetting fine water droplets into the water guide pipe. It is configured to have holes.

Further, the predetermined diameter of the fountain hole in the above configuration is set to be 0.2 mm or more and 0.5 mm or less.

[0008] The fountain holes are arranged in the water pipe so that fine water droplets from the fountain holes in each of the above-described structures are ejected obliquely upward when viewed in the axial direction of the water pipe.

Further, the flower stand according to the present invention comprises:
Equipped with a base on which a planter or the like is placed, the panel body is erected upward at the rear of the base, and any of the above-described water sprinklers is extended from the upper end of the panel body and placed above the base. The fountain holes are arranged in the water pipe so that the fine water droplets that are ejected are directed to the base or the panel body.

[0010] The panel body in the flower stand may include at least one panel standing upward at a rear portion of the base.
It comprises a pair of metal columns and a wooden panel supported between the metal columns, wherein the metal columns and the wooden panel are supported and fixed via a connecting tool at a distance from each other.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an external view of a sprinkler according to an embodiment of the present invention including a partially cut-out portion, and FIG.
It is a sectional view on the AA line of a sprinkler in. In each of the drawings, a sprinkler 1 according to this embodiment is mainly constituted by a water guide pipe 2 into which pressurized water W is introduced, and a large number of fountain holes 3 which communicate with the inside and outside of the water guide pipe 2. I have. The opening at the tip of the water pipe 2 is sealed by a cap 4 which is heat-welded. The water pipe 2 is made of a synthetic resin such as hard polyvinyl chloride, for example, and has an inner diameter of 13 mm.
However, the material is not limited to the above-mentioned hard polyvinyl chloride as long as it is a material that can withstand the water pressure of the pressurized water W and does not change the opening diameter and the opening shape of the fountain hole 3. The fountain hole 3 is drilled by a drilling machine manufactured by PICC Co., Ltd., and is formed so fine that the presence of the hole cannot be visually recognized on the surface of the water guide tube 2 without staring. Here, the fountain hole 3 in the water pipe 2
Two rows of openings are provided diagonally upward on both sides as viewed in the direction of the axis C of the water pipe 2. When the length of the water pipe 2 is 1 m, 1
Fountain holes 3 with 50 rows and 20 mm pitch are 2 rows total 100
Individually formed.

In this embodiment, a predetermined opening of the fountain hole 3 is performed.
The diameter D is set to, for example, 0.3 mm. In addition,
Constant water pressure (for example, 1.5 to 3.25 kg / cm^Two)
When using the retained tap water, a predetermined opening diameter of the fountain hole 3
If D is set between 0.2mm and 0.5mm
Good. When the predetermined opening diameter D exceeds 0.5 mm,
The water distribution varies between the fountain hole 3 close to and the fountain hole 3 far away.
Occurs. In addition, the ejected water droplets are relatively large and fine
The momentum is too strong to damage the flowers
It becomes. On the other hand, when the predetermined opening diameter D is less than 0.2 mm
Requires high-precision drilling and increases production costs
You. In addition, the reach of the ejected fine water droplets R is reduced.
In addition, it takes too much time to complete certain watering.
As the pressurized water W introduced into the water pipe 2, for example,
Almost 2.0kg / cm ^TwoTap water is used. Introduced
The pressurized water W is maintained at a predetermined water pressure in the water pipe 2.
Is desirable. Adjust the water pressure of pressurized water W with a water tap
Or a water stop valve interposed between the water tap and the water pipe 2
It is also possible to adjust with.

Next, the watering operation of the watering device 1 having the above-described configuration will be described. When the pressurized water W is introduced into the water guide pipe 2 in a state where the water sprinkler 1 is arranged on the ground such as a flower bed, countless fine water droplets R are ejected from each of the fountain holes 3 at the same time. The ejected fine water droplets R scatter in a parabola and fall not only on the petals and leaves of the flowers but also on the back of the leaves. The diameter of the fine water droplet R is 0.4 to 0.4 in a rounded state.
It is about 8 mm. Incidentally, depending on the water pressure in the water pipe 2, in this embodiment, the distance from the fountain hole 3 at which the jetted water is rounded to become a fine water droplet R is determined when the predetermined opening diameter D of the fountain hole 3 is 0.1 mm. It was about 25 cm when it was about 5 cm, 0.3 mm, and about 100 cm when it was 0.5 mm.

Therefore, according to the sprinkler 1, since the soft fine water drops R are given to the petals and leaves of the flowers, the flowers are not damaged. If the inner diameter of the water pipe 2 is sufficiently larger than the predetermined opening diameter D of the fountain hole 3, the water pipe 2
Since the ejection amount and ejection state of the fine water droplets R hardly change between the tip side and the water tap side in, water can be uniformly sprayed. As a result, the water supply can be sufficiently performed without bias, so that, for example, cuttings and the like may be grown. Further, watering can be started from all the fountain holes 3 simply by opening the water tap, so that watering is easy. And since the structure of the sprinkler 1 is simple, it can be manufactured at low cost.

Several application examples using the above-described water sprinkler 1 will be described below. First, as shown in FIG. 3, an example of a watering system 10 for watering the flowers F planted in a large number on the flower bed 9 is illustrated. In the watering system 10, the main pipe 6 is arranged on one side in the flower bed 9 in the shape of a plane square. A plurality of sprinklers 1 extending in the short side direction of the flower bed 9 are branched from the main pipe 6. The water guide pipes 2 of the sprinkler 1 are connected to the main pipe 6 via branch pipes 5, respectively. A main pipe 6 is connected to a connection pipe 8 connected to a water tap via a water stop valve 7.

Here, the fountain hole 3 is, as shown in FIG.
The drilling position or drilling angle in the water pipe 2 is set such that the fine water droplet R is ejected obliquely upward when viewed in the direction of the axis C of the water pipe 2. For example, as shown in FIG. 4A, the angle θ1 (= about 120 degrees) about the axis C of the water pipe 2
And two rows each having an angle .theta.2 (= approximately 40 degrees) even at the same 120 degrees as shown in FIG. Further, as shown in FIG.
A row of fountain holes 3 can be provided at the row and at an oblique position that is at an angle θ3 (= about 25 degrees) from the row. If the water pipe 2 having the fountain holes 3 as shown in FIG. 3C is used as the sprinkler 1 adjacent to the short sides at both ends of the flowerbed 9, it is convenient because the fine water droplets R do not fly out from the short side. .

According to the watering system 10, water does not jump out of the flower bed 9, and water can be uniformly sprayed into the flower bed 9 by just twisting the water stop valve 7. Therefore, water is not wasted and there is no unevenness in watering. Although the water pipe 2 is made of polyvinyl chloride and cannot be said to have an aesthetic appearance, it is hidden when the flowers F grow, so that the flowers F appear to be visible.
Does not detract from the aesthetics of

Next, an application example of watering a flower bed using a fence or the like is shown in FIGS. In the fence-mounted system shown in each figure, a water sprinkler 1 is fixed along the lateral direction on the side surface of a U-shaped holder 12 that opens downward. The holder 12 is formed in a size that can be fitted to the upper end of the block wall 11. The holder 12 is provided with a cover 13 that covers the sprinkler 1. This system also provides a flower bed 9 along the block wall 11, and the flower bed 9
The holder 12 is mounted on the upper end of the block wall 11 so that the sprinkler 1 is arranged on the side. At this time, it is not necessary to form the fountain holes 3 in the sprinkler 1 at a wide angle, and for example, a plurality of rows may be formed within a range of about the angle θ3 in FIG. According to this wall-mounted system, the block wall 1
Watering can be easily performed on the flowers planted in the flower bed 9 adjacent to 1 or the like.

Next, an example in which the sprinkler 1 is applied to a flower stand is shown in FIGS. In each of the figures, the flower stand 14 includes left and right bases 15, 15 that support a substrate 16 on which a planter 25 is placed. These bases 15, 15 are connected at their rear portions 28 by horizontal rods 29. Also, the rear portions 28, 2 of the bases 15, 15
8, two panel bodies 21 are provided upright. Among them, the panel body 21 disposed on the forward inclined portion above the metal pillar 17 has a function of holding the flower pot 27, of course,
It also has a function to reduce the amount of sunshine and a function to prevent flower knocking due to raindrops during heavy rain.

The water sprinkler 1 extends from the upper end of the upper panel body 21 and is disposed so as to face above the base 16. The fountain hole 3 of the sprinkler 1 is formed in the water pipe 2 so that the ejected fine water droplet R is directed to the substrate 16 or the panel body 21. However, when the flower pot 27 is not attached to the panel body 21, the fountain hole 3 may be arranged so as to direct only the substrate 16. Base 15
A caster (reference numeral is omitted) is attached to the lower surface of the, and the flower stand 14 is movable.

The panel body 21 is mainly composed of a pair of left and right metal columns 17, 17 standing upright on a rear portion 28 of the base 15, and a wooden panel 20 supported between the metal columns 17, 17. It is configured. The metal column 17 is made of a steel pipe or the like and is formed in a hollow cylindrical shape. A connection tube 23 connected to the sprinkler 1 by piping is inserted into one of the metal columns 17. The other end of the connection tube 23 is connected to the connection tube 8 via the water stop valve 7. Further, a cover 22 that covers the upper part of the sprinkler 1 is provided at the upper ends of the metal columns 17. The wooden panel 20 is composed of a lattice plate 18 having a square shape in a front view and formed in a diagonal lattice shape, and an outer frame 19 surrounding the periphery of the lattice plate 18. A flower pot 27 is attached to the lattice plate 18 of the wooden panel 20 by using an S-shaped hook 26.

The wooden panel 20, the metal column 17 and the horizontal rod 30 are arranged apart from each other, and are supported and fixed via a connecting member 34 represented by a wood screw or the like. The connector 34 is screwed into the outer frame 19 from the hole 32 formed in the metal column 17 through the hole 33 and the holding tube 31 (see FIG. 10). After the screwing of the coupling tool 34 is completed, the hole 32 of the metal pillar 17 is formed.
Is sealed with a cap 24. The connecting member 34 is the outer frame 1
Although the screw is directly screwed into the connector 9, an anchor female screw (not shown) may be embedded in the outer frame 19, and the connector 34 may be screwed into the anchor female screw.

As described above, this flower stand 1
According to 4, with respect to the planters 25 placed on the substrate 16 and the flowers in the flower pot 27 suspended on the panel body 21,
Watering of the soft fine water droplets R can be performed. In addition, in constructing a large flower stand, even when the rigid metal pillar 17 is used for the configuration of the panel body 21,
The wooden panel 20 supported and fixed to the metal column 17 is the metal column 1
No direct contact with 7. Therefore, the outer frame 19 of the wooden panel 27 is less likely to decay and the metal pillars 17 are less likely to corrode as compared with the case where they are directly attached, so that they can be used stably for a long period of time.

The number of metal pillars used in the flower stand is not limited to two as in the above-described embodiment, but may be three or four or more. If the flower stand is not large, the present invention can be applied even if the panel body is entirely made of wood.

[0025]

As described above, according to the sprinkler according to the present invention, since the fountain hole having a predetermined opening diameter is formed in the water pipe, the pressurized water introduced into the water pipe is finely dispersed from the water hole. Spouts out as water drops. Therefore, soft fine water droplets are given to the petals and leaves of the flowers, so that the flowers are not damaged. When the inner diameter of the water pipe is sufficiently large with respect to the predetermined opening diameter of the fountain hole, there is almost no difference in the amount and state of fine water droplets ejected between the tip side and the water tap side of the water pipe. Water can be sprinkled evenly.

In the case where the fountain hole is arranged in the water pipe so that fine water droplets from the water fountain hole in the water sprinkler having the above-described structure are ejected obliquely upward as viewed in the axial direction of the water pipe,
When a water sprinkler is arranged between flowers planted on a flower bed or the like, fine water droplets are sprayed obliquely upward. This makes it possible to spread soft watering on the petals, stems, leaf surface, or back of the flowers.

Further, according to the flower stand of the present invention, the fountain hole is formed in the water pipe so that the fine water droplets jetted from the water sprayer arranged above the base point toward the base or the panel body. Because it is arranged, on the planters placed on the base and flower plants hanging on the panel body,
Watering of soft fine water droplets can be performed.

Further, when a large-sized flower stand is constructed, even when a rigid metal column is used for the configuration of the panel body, the wooden panel supported and fixed by the metal column does not directly contact the metal column. Therefore, the wooden panel and the metal pillar are less likely to decay as compared with the case where they are directly attached, and can be used stably for a long time.
