Description

[Technical field]

[0001] This invention relates to watering plants. [Background technology]

[0002] Watering tools for plants include a watering can or a hose with a shower head attached to the end, but they have the problem of getting water onto the leaves. One of the representative methods to avoid this is to use a water supply string, as shown in Figure 2 of Publicly-Published Practical Application No. 2-137854. This water supply string is made of capillary wicking material such as nonwoven fabric. Another method is to use a spray pen, as shown in Photos 5 and 6 on page 287 of the August 1998 issue of Modern Agriculture. [Prior art documents] [Patent documents]

[0004] [Non-Patent Document 1] Modern Agriculture, Rural Culture Association, August 1998, P. 287 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above paragraphs (0002), items 1 and 2, watering is localized, and the amount of watering on the opposite side of the trunk of the plant is small. A more effective watering device that solves these problems is required. The same applies to the nutrient solution, but it is simply called water. Also, when using pots, as the plant grows and the leaves thicken to cover almost the entire surface of the pot, even if you water it with a watering can, a large amount of the water will flow outside the pot, making it necessary to push aside the leaves to water it. [Means for solving the problem]

[0006] We have researched a system that envelops the trunk of a plant and allows water to be irrigated around the entire trunk with a single injection tool. It is as shown in Figure 1. This porous pipe 1 is a hose with many tiny holes that allows water to slowly seep out. Injection tool 2 is a T-shaped tee used at the connection points of hard polyvinyl chloride pipes. There are problems with the system shown in Figure 1. The first is that when groundwater is used as the water, impurities and organic matter become entangled in the tiny holes in the porous pipe 1. The second is that it requires water pressure similar to that of household tap water.

[0007] Next, I thought of something like Figure 2. Hose 3 is a transparent hose or an opaque anti-algae hose. Injection tool 2 is a T-shaped T-shirt. Hose 3 is bent into a circle and joined with injection tool 2. Next, water is injected into hose 3 using a watering can or similar. A number of outlet holes 4 are provided at the top of the hose 3, and capillary suction materials 5 are installed in each of them in a mountain shape to suck up the water in the hose 3 and drop it. The position of the falling water is near the symbol A below the tip of the capillary suction material 5. As shown in Figure 2, in the early stages of the plant 6, the roots of the plant 6 are short and are far from the symbol A below the tip of the capillary suction material 5. This is shown in Figure 2 by the mark < >. As a method of bringing them closer, a flexible straw 7 is used as shown in Figure 3, and capillary suction materials 5 are inserted into it to drop water from the tip of the flexible straw 7 so that it falls near the growing point of the plant 6 close to the trunk. As the plant 6 grows and its roots extend, the growing part will naturally move away from the trunk. If the flexible straw 7 is rotated accordingly to drop water from the tip of the flexible straw 7, more efficient watering can be achieved. This is shown in Figure 4. The method of inserting the capillary suction material 5 into the flexible straw 7 and the aluminum wire 8 are shown in Figure 5 (a), (b), and (c). As shown in (a), the capillary suction material 5 and the flexible straw 7 are aligned, and the thin aluminum wire is bent into a U shape, sandwiching the capillary suction material and passing it through the flexible straw. The purpose of the aluminum wire 8 is to have a resistance greater than the elasticity of the flexible straw 7, so that the flexible straw 7 can maintain its shape when it is bent.

[0008] In addition to the hose 3, the trunk of the plant 6 is surrounded by a rigid polyvinyl chloride pipe 9 and a 90 degree elbow 10, as shown in FIG.

[0009] A hose or hard polyvinyl chloride pipe (or a molded product equivalent to the above) is attached to the top of the injection tool 2 as an extension 11 that is taller than the height of the plant, and water is poured into this extension. Even if the plant grows and the leaves become lush and cover almost the entire surface of the flowerpot, there is no need to push aside the leaves to water it. This is shown in Figure 8. The symbol B indicates the top of the plant 6. [Brief description of the drawings]

[0011] An opaque anti-algae hose with an inner diameter of 18 mm and an outer diameter of 24 mm is bent into a circle and connected with a T-shaped cheese as an injection tool, and water is injected. A number of outlet holes are provided at the top of this hose, and capillary suction material is installed in each of them in a mountain shape to suck up the water in the hose and drop it. The water falls near the tip of the capillary suction material. In the early stages of the plant, the roots of the plant are short and far from the tip of the capillary suction material. A flexible straw is used as a way to bring them closer, and a capillary suction material is inserted into it, and water is dropped from the tip of the flexible straw to fall near the growing point of the plant. As the plant grows and the roots extend, the growing part will naturally move away from the trunk. If the flexible straw is rotated in response to this and water is dropped from the tip of the flexible straw, more efficient watering can be achieved. The flexible straw has an outer diameter of about 6 mm, and the capillary suction material placed inside is 4 to 5 mm wide so that it fits just inside the flexible straw. Figure 7 shows an injection tool using a vinyl tube instead of a T-tee. [Explanation of symbols]
