Description

The present invention relates to the structure of water spray holes such as small rain dew.

Conventional water sprinkling structures such as small rain dew are roughly classified into outdoor use in which a large number of small-diameter holes are opened at a sprinkling outlet that has become wide and a water discharge line is diffused, and a water bottle type indoor that is not diffused through a single hole.
The diffusion type is often used under conditions that are not affected by water wetting (outdoors). In a room such as a living room or office, there is a concern about water wetting around, so a single hole with a water outlet diameter of about 6 to 7 mm is used. There are many cases using a small jug type that does not diffuse.
However, there are many problems with the use of these irrigation devices, especially when using a jug type for irrigating indoor plants such as offices and living rooms and small bonsai, it is easy to adjust the amount of water discharged. Rather than partial irrigation, if you adjust the pitch of the pitcher to adjust it, water drops often due to changes in the water pressure and wets the surroundings. In some cases, he had to give up the installation of foliage plants. Even under conditions where installation is allowed, there are many cases where it is inconvenient that the water is moved to another place each time it is irrigated and restored.
In addition, since delicate adjustment of the irrigation amount cannot be performed, makeup topsoils such as bonsai pots arranged for ornamental use are damaged by water discharge, often resulting in a loss of the beauty of the corner.

Therefore, in the present invention, it has an accurate and stable water discharge line, it is possible to finely adjust the irrigation amount, there is no dripping of water even when irrigation is stopped, and it is applied to the surface cosmetic soil by a thin and soft water discharge flow. Provide indoor rain dew that can be inserted into an existing pitcher without impact.

The indoor rain and dew sprinkling structure S of the present invention is formed by bundling a large number of pipes each having a small diameter of an appropriate length with an elastic tube, and further, an elastic hose for connection with an existing jug water pipe G on its outer membrane This is an irrigation accessory part that is used by inserting the hose into the water outlet. See Figure 1

Structural condition according to claim 1 and the tube flow situation has a structure dispersed to discharge water and the flow from the water conducting hole 4 into a plurality of small diameter pipes, the more resulting flow inertia to the tube flow, when irrigation The water discharge has an accurate and stable linear direction. At this time, the principle of increasing the flow velocity in the small-diameter pipe 5 of the liquid is applied, and the small-diameter pipe is caused by the negative pressure caused by the reverse action of the reverse flow in the water supply pipe G caused by returning the tilt of the container when irrigation is stopped. The backflow speed of the residual water in the passage increases, and a strong suction action is generated inside to prevent the residual water in the small-diameter pipe 5 from dripping. See Figure 2

As shown in FIG. 3, the sandwiching and clamping component 6 having a wedge shape between the small-diameter pipes is uniformly sandwiched and interposed between the small-diameter pipes and the small-diameter pipes are bound by the elastic tube 2. Thus, each water discharge hole is radially formed with an appropriate separation, and it is possible to arbitrarily select the exact induced water discharge and its irrigation range by making each water discharge line independent without the water discharge flows joining each other. Become.

To make further facilitate sucking action due to backflow of water pipes G during watering stop, by the lower long upper and obliquely cut shape as shorter than the water discharge direction tip shape 8 of the water discharge hole, the surface tension The residual water remaining in the small-diameter hole is sucked into the inside of the water supply pipe G by the suction action of the small-diameter pipe 5 and the dripping prevention effect is enhanced. See Figure 3

There is no need to wet the surroundings when irrigating foliage plants and small bonsai, and because it can induce a soft and accurate water discharge, sufficient irrigation is possible without damaging the cosmetic topsoil, making it comfortable for small indoor foliage plants. Has irrigation conditions.
Therefore, it becomes possible to easily enjoy the indoor plant interior without worrying about water wetting at the time of conventional irrigation in the room and office, and it is expected that the indoor air cleanliness and the mental relaxation effect are also achieved.

If a diameter of 2.4 mm diameter pipe as an example of a prototype test, a radiation angle required for mutual separation and 5 ° to 7-° C., so that the respective spacing slightly wider than the diameter of the small diameter pipe, the small diameter pipe Set the length of.

It is an image figure of the example of attachment use. It is a figure of this apparatus. It is sectional drawing and functional drawing of this apparatus.

Claims (1)

The structure of sprinkling holes for rain dew is a converging body consisting of a small-diameter pipe 1 having an appropriate length that promotes inertial flow, and the flow inertia generated in the small-diameter pipe causes a residual water backflow in the water supply pipe G during irrigation stop operation. Indoor rain dew , characterized by a suction action that prevents dripping of water droplets.
