[0003]

However, in the above-mentioned conventional configuration, there is a problem that only the amount of water according to the size of the fiber bundle is supplied, and the amount of water supply cannot be limited, so that it is difficult to use. In addition, the amount of water supply is insufficient for plants with large transpiration and large flower pots, and the water supply is too small for plants with small transpiration and small flower pots. There was a problem of getting wet.
Further, there is a problem in that the tube is so flexible that it is easily bent, so that water can be supplied only to a flower pot in the vicinity of a water storage tank and water cannot be supplied to a flower pot in a remote place.

The present invention solves the above-mentioned conventional problems, in which the amount of water supply can be freely limited, an optimum amount of water can be supplied according to the type and size of the plant, and the water at a location remote from the water storage tank can be provided. An object of the present invention is to provide an automatic water supply device for plants that can supply an optimal amount of water to a flower pot or a plurality of flower pots.

[0005]

In order to achieve this object, an automatic water supply device for plants according to claim 1 of the present invention comprises a soft pipe and a water pipe inserted into the soft pipe except for both ends. and sex fiber bundle, folding is fixed to an end portion of at least one end portion is inserted into the soft pipe the soft pipe itself
And the existing metal filaments. The automatic water supply device for plants according to claim 2, wherein the soft pipe, a straight pipe or a branch pipe hard pipe disposed and fixed at one end or both ends of the soft pipe, and the soft pipe and the hard pipe. 1 or a plurality of water guide fiber bundle is inserted leaving both end portions, folding said soft pipe and is inserted into the rigid pipe at least one end portion is fixed to an end portion of the soft pipe and / or rigid pipes And one or a plurality of bendable metal filaments.

Here, as the soft pipe, a pipe made of a flexible synthetic resin such as polyethylene, polypropylene or nylon is mainly used. Sectional shapes are circles, ellipses,
A polygon or the like is used. As the water-conducting fiber bundle, a nonwoven fabric, felt, cotton, or the like having a water supply capability by a capillary phenomenon is used. As the metal wire, a material such as a stainless steel wire or a copper or iron wire coated with a synthetic resin, which can be easily formed by bending and has a shape retaining property for maintaining the processed shape is used. The hard pipe is used as a weight or when a soft pipe is attached to a predetermined portion of a water storage tank or a flower pot with a pinch or the like, and a synthetic resin pipe, a ceramic pipe, a metal pipe, or the like having a large specific gravity is used. When water is supplied to a plurality of flower pots in addition to a straight pipe, a branched pipe is used.

Since it is a hard pipe, the holding power of the clippers 9a and 9b is strong, and water can be supplied without crushing or constriction. Since the soft pipe 2a is formed and held high in the form of a mountain at the peak 2a 'in the metal filament 5, the amount of water flowing by the capillary phenomenon is smaller than that of the soft pipe 2b, so that the supplied water is at the root of the plant. It does not leak from the bottom of the pot and wet the floor. Further, since the soft pipe 2b is not formed in a mountain shape, a large amount of water can be supplied at the root. Further, since the metal filaments 5 are contained, a large amount of water can be supplied to the root of the plant to a great distance without bending.

Next, an experiment was conducted on the relationship between the height and the amount of water supply for the automatic water supply device for plants of the present embodiment. FIG.
