DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically supplying water to a flower bed.

[0002]

2. Description of the Related Art As a device for automatically supplying water to a flowerbed in which a lower part of a culture soil is always filled with water, a water tank in which a valve of a water supply pipe is controlled by a lever-type water level adjusting float similar to that conventionally used for flush toilets. Is connected to the lower part of the flower bed.

[0003]

In the flowerbed equipped with the above automatic water supply device, since the water always fills the lower layer in a state of waist water, the lower layer of the culture soil is sealed with water, There is almost no circulation of air in the soil. Therefore, it hinders the growth of the plant roots, and thus the whole plant. In particular, when the rain continues, the water level at the bottom of the flowerbed rises more and causes root rot.

[0004] It is an object of the present invention to improve air permeability in a culture soil including a lower part of a flower bed provided with an automatic water supply device, and to keep the humidity of the culture soil almost always constant.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an automatic water supply device for flower beds according to the present invention will be described with reference to FIGS.

The automatic water supply device includes a constant water level water supply device 1 connected to a water supply source such as a water supply or a tank, and a constant water level water supply device 1.
And a perforated drain pipe 2 extending from the lower part of the side wall to the bottom in the flower bed 3 and connected to the excess water discharge port 3a provided on the side wall of the flower bed 3. In addition, there is no mouth other than the excess water drainage port 3a at the bottom and the side wall of the flower bed 3,
It has a watertight structure as a whole.

The fixed water level water supply device 1 is provided with a nozzle 11 to which the water supply pipe 3 is connected at an upper part, a drainage port 12 at a lower part, and a water stopcock 13 extending to a water outlet of the nozzle 11 inside. A protruding float 14 is housed therein, and is a closed hollow container except for the nozzle 11 and the drain port 12. The cross-sectional shape of the constant-level water supply device 1 is a circular shape in the drawing, but is not particularly limited thereto. Here, the fixed water level water supply device 1 is housed in the flower bed 3, but it can be installed outside. In that case, the porous ventilation drain pipe 2 is connected to the drain port 12 through a hole provided in the side wall of the flower bed 3. Also, a plurality of perforated drainage pipes 2 for a plurality of flower beds can be extended from the lower part of the side wall of one constant-level water supply device 1. Furthermore, a plurality of flower beds 3 can be installed on a different level or on the same plane, and water can be supplied from a single water supply pipe 5 to the constant water level water supply device 1 corresponding to each flower bed 3. In addition, 15
A nut 1a for fixing the nozzle 11 to the upper part of the constant-level water supply device 1 is a ventilation hole.

The water stopcock 13 is slidably inserted into a through hole of a sheath tube 17 fixed to the nozzle 11 by a nut 16. Further, the outer diameter of the water stopcock 13 is larger than the inner diameter of the nozzle 11 and smaller than the inner diameter of the sheath tube 17, and the tip thereof is pointed conically. And the nozzle 1 that receives it
A packing 18 made of rubber or the like is attached to the end of the water outlet 1. The length of the water stopcock 13 is determined by the water level fixing screw 19 and the level of the water level 6 in the constant water level water supply device 1. 1b is a lid, which is a water level fixing screw 19b.
Can be adjusted by opening the lid 1b. Although the water stopcock 13 shown in FIG. 5 has a conical tip, the tip may be flat. In this case, if a rubber plate is attached to the tip of the water stopcock 13 and the inner diameter of the nozzle 11 is made sufficiently small, the buoyancy of the float 14 can sufficiently receive the water pressure flowing out of the nozzle 11.

The water supply pipe 5 is directly connected between the constant-level water supply device 1 and a pipe 4 of a water supply source such as a water supply or a tank without any other electromagnetic control valve or the like.

As shown in FIG. 4, perforated drainage pipes 2 are provided with small holes 2a which allow air or water to enter and exit at predetermined intervals over the entire circumference. In FIG. 2, a plurality of perforated drainage pipes 2 are connected in parallel by other front and rear pipes, but one may be meandering.

The automatic water supply device having such a configuration is laid at the bottom of the flower bed 3, and the water level fixing screw 19 is set so that the water level 6 becomes lower than the middle of the perforated drainage pipe 2 and the upper part becomes a ventilation section. Operate to adjust the position of the float 14. At the bottom of the flowerbed 3, a culture soil such as pumice stone, artificial soil, Kanuma soil and the like, which is excellent in air permeability and water retention, is put, and a normal culture soil is put thereon, and a plant is planted.

When water is supplied to the water supply pipe 3 from a water supply pipe 4 such as a water supply or a tank, the water is supplied to the nozzle 1
1, the water enters the inside of the constant-level water supply device 1 through the gap between the sheath tube 17 and the water stopcock 13, and flows out of the drain port 12 to the perforated vent pipe 2. The water permeates the culture soil of the flower bed 3 from the small hole 2 a of the perforated drainage pipe 2, penetrates all the way, and accumulates at the bottom of the flower bed 3. At this time, the water level 6 rises, and the float 14 floats with it, and the water stopcock 13 rises. Then, the tip of the water stopcock 13 abuts on the outlet end of the nozzle 11. Thereby, the outflow of water from the nozzle 11 stops. The water level 6 at that time is lower than the middle of the perforated drainage pipe 2.

The water collected at the bottom of the flower bed 3 is successively absorbed into the culture soil as the culture soil loses moisture by evaporation and evaporation. Then, when the water level 6 of the flower bed 3 becomes equal to or less than a predetermined value, the water level in the constant water level water supply device 1 also drops, and accordingly the float 14 and the water stopcock 13 lower again, so that the nozzle 11 is in a water-permeable state. Water is supplied. Excess water such as rain is discharged from the excess water drain 3a of the flower bed 3, and the water level 6 is changed to the perforated vent drain 2
Is always kept below the middle.

Therefore, the air passing through the small holes 2a of the perforated drainage pipe 2 is irrespective of the rain and the rain, the air between the coarse particles of the cultivated soil forming the lower part of the flower bed 3 and having excellent air permeability and water retention. It is continuous. The air in the culture soil can easily move due to a change in atmospheric pressure, a movement of water due to evaporation and evaporation, a temperature difference between outside air and the culture soil, rainfall, and the like.

[0021]

Since the present invention is configured as described above, it has the following effects.

That is, since the air permeability in the culture soil including the lower part of the flowerbed equipped with the automatic water supply device is improved irrespective of the weather, it is necessary for the respiration of plant roots and the decomposition of organic matter in the culture soil. Sufficient oxygen can be sufficiently supplied, and the oxygen deficiency state of water which tends to stay on the culture soil and the bottom can be prevented. In addition, the humidity of the culture soil can be kept almost constant at all times. Therefore, an optimum rooting state of the plant can be obtained, growth is promoted, root rot does not occur, and there is no growth of the root, so that special work such as replanting is not required. In addition, there is no need for watering, no skill is required, and there is no loss of fertilizer due to watering. Since the automatic water supply device has a built-in nozzle and float, it is compact, easy to assemble and handle, and has high reliability.
