Description

Water dosing device for self-irrigation

Background of the invention

Soils, climates and plants have very different characteristics, it depends on this extensive combination the amount of water required by each plant. A general is how to know, calculate or dose the exact amount of water required for each of them and even more so if users have had almost or no approach to these issues.

In some regions, water from rivers, lakes or lagoons as well as rainwater is contaminated, a problem faced by some proposals that use piped water or from nearby water sources to power their irrigation devices.

On most of the planet, drinking water is a topic that has become of vital importance due to its scarcity. We face in a term that this issue becomes a crucial problem as well as that of food. To optimize or improve the irrigation of plants, several techniques or designs are known based on the exchange of water called some self-irrigation.

There are some designs that use capillarity using hydrophilic strips or wicks that link the water container with the container that contains the earth, such as:

One more solution was: Flooding and draining, at the bottom of the pot there is a water tank, there is a channel that goes from the base to the top of the pot through which a hose is introduced, to fill the tank and the water goes up to flood the earth, by the same hose the excess water is extracted, to leave the lower space empty so that the water that the plant failed to absorb falls, for example

World Industrial Property Organization (WIPO) AO1G 27/00 (2006.01) Another solution was: A totally porous pot, the walls and base that contains the soil and the plant and is totally submerged in a container full of water, example

The solution found was; A glass container with a rib on the inner perimeter where a porous ceramic lid that allows the passage of water sits, these 2 elements form a reservoir for water. In order for the capillarity phenomenon to occur, it is necessary that the water has contact with the surface, in this case the lid, as soon as the water begins to pass, the water level drops and the lid stops making contact, so the passage of water is interrupted, remaining stagnant in the container. The lid rests on the rib of the container without any cello, so that when filling the reservoir of water, it can pass and flood the area where the earth is.

Figure 19 shows how you can put several water dosing devices in line and feed the water through the line from a drinking water cistern. Detailed description of the invention

In figure 1 and 2 the water dosing device is shown, which presents in an embodiment as an elongated ellipse, this device is formed by a permeable ceramic lid (1) or any material that admits the phenomenon of capillarity and allow water to pass through it; a filling duct (2) of ceramic or any material, this duct has two ends, the upper end of the duct (3) is where water is introduced and the lower end of the duct (4) joins the lid (1) , so that there is fluid passage of water through the pipeline, the water reaching the reservoir (7) where it is stored waiting for it to pass through the lid (1).

Referring to said figures 1 and 2, there is also shown a base (5) from which walls (6) protrude, this base (5) and walls (6) are made of waterproof ceramic or any material, such that the periphery of the cover (1) joins by means of a seal (8) with the periphery of the walls (6) forming a cavity (7). The seal (8) has the function of preventing water from protruding from the cover (1) at the point of connection with the walls (6). Likewise, there is a passage of fluid around and under the cover (1) inside the cavity (7), the space between these elements being larger.

The dosing device works as follows: when water is introduced through the upper end of the filling duct (3), the water passes into the cavity (7) of the water dosing device, so that the entire cavity is filled and even the filling duct is filled. This water tank allows the water to remain inside the dosing device and does not leak through the base (5) and walls (6), due to the capillarity principle, the water can rise through the lid (1), since it is made of permeable ceramic or any material that admits the phenomenon of capillarity. This effect is more clearly visualized in Figure 17. The dosing device shown in figures 1 and 2, are of ellipsoidal configuration, but can take different configurations, for example, in figures 3 and 4 the dosing device is of circular configuration; in figures 5 and 6 the dosing device is of square configuration; in figures 7 and 8 the dispenser is of ellipsoidal configuration, and can be the dosing device of different configurations.

In the embodiment shown in Figures 3 and 4, it is observed that the base (5) is circular and that walls (6) protrude to a greater height forming a pot (11), since both the base (5) and the walls (6) They are waterproof, water will not leave this potted body.

From the same figures 3 and 4, it is observed that inside the pot (11) a lid (1) is placed at the bottom and as detailed in figures 1 and 2 above, the filling duct (2) is also placed attached to the lid (1) forming a fluid passage of water into the cavity (7), taking into account that the lid (1) is made of permeable ceramic or any material that admits the phenomenon of capillaryness. Water is poured through the top of the filling duct (2) ensuring that water can only be supplied to the interior of the water receiving cavity (7). This is also ensured given the seal (8) of the cover (1) and the walls (6). The device is used, see figure 18, so that the soil is placed inside the pot (11) and in this pot is the plant, so once the water dosing device is filled, by capillarity, the water rises to the earth through the lid (1) of permeable ceramic or any material that admits the phenomenon of capillarity, supplying water throughout the region of area that has this lid, supplying water uniformly, that is, the roots are distribute evenly in the pot and drink water from the dosing device. The water supply is natural and does not need to be checked, only the user must refill the dosing device by pouring water through the filling duct (2) until the duct is full. The U-profile of the lid (1), allows the water to always be in contact with the lid regardless of the level of existing water, water is provided over the entire surface of the lid (1) when the water decreases and this Low level is still supplied mainly by the central part of the lid (1) that has a U-configuration that allows this area to continue supplying by capillarity the rest of the water that is still in the dosing device.

Figures 5 to 8 have similar dosing devices to that described and shown in Figures 3 and 4, but the type of configuration of the device varies, and other configurations may be available, for example, square or ellipsoidal and of different sizes.

In figures 1 to 8 a pot or container is obtained that has the permeable lid (1), the waterproof walls and base, the dosing device can also be independent and can be placed inside a container (figs 9 to 16) that can be of any material such as wood, plastic, glass, etc. or it can be an integral part of the pot (figslal 8), using the walls and floor of the pot. The lid or upper part is permeable allowing the passage of water by capillarity. The soil or substrate is placed on top of the dosing device or lid, allowing the plant to absorb water by capillarity at its free demand, as in the nature from the bottom up. Mainly they are for interiors or greenhouses, in the case of exteriors they are made a hole (11) to drain the excess of rainwater. When the container is of a regular size, another duct (10) can be added as a vent (fig16).

In Figures 9 and 10, a water dosing device is shown that has a permeable ceramic lid (1) or any material that admits the capillarity phenomenon, a filling duct (2) that is attached at one end to the lid (1) allowing the passage of water fluid into the cavity (7). It is also noted that there is a base (5) and walls (6), both of waterproof ceramic or any waterproof material, the walls are attached by a seal (8) to the cover (1). This arrangement shows a rectangular configuration of the dosing device and the U of the center of the lid an ellipsoidal shape, this can be introduced into a pot or container of any material, which is shown with segmented lines (9) to illustrate a way of use, that is, the pot or container may have a configuration similar or equal to the dosing device, with slightly larger dimensions so that it can accommodate the water dosing device.

The dosing device shown in figures 9 and 10 may, in turn, have other configurations, for example in figures 11 and 12 it has a circular dosing device; A square configuration is shown in Figures 13 and 14 and an irregular configuration is shown in Figures 15 and 16.

Figure 17 shows a section of the water dosing device, this device is formed by a lid (1) of permeable ceramic or any material that admits the phenomenon of capillarity and allows water to pass through it; a filling duct (2) of ceramic or any material, this duct has two ends, the upper end of the duct (3) is where water is introduced and the lower end of the duct (4) joins the lid (1) , so that there is fluid passage of water through the filling duct (2) reaching the water to the tank (7) where it is stored waiting for it to subsequently pass through the lid (1). A base (5) is shown the walls (6), this base (5) and walls (6) are made of waterproof ceramic or any material, such that the periphery of the lid (1) is joined by a seal (8) ) with the walls (6) forming a cavity (7). The seal (8) has the function of preventing water from protruding from the cover (1) at the point of connection with the walls (6).

Figure 18 shows operation of the water metering device for self-irrigation in pots in use mode, in which it is observed that the water is introduced through the filling tube (2) and the water is stored inside the tank (7) formed by the lid (1) and the base (5) and walls (6), the dosing device is observed either forming or being part of a pot or container and providing water to the plant through the lid ( one). With this principle the dosing devices of figures 1 to 16 operate.

The water dosing device can be placed in open areas with limits of any kind such as a fence to contain the soil or substrate as for gardens, planters or growing areas.

When there are several water dosing devices, a line of pipes can be laid joining the ducts to fill them in line having a water tank at the beginning of the line (fig 19)

Applications Water dosing device can be integrated into the pot or be part of it according to the size and need required.

In its smallest form it can be used as seedbeds or with small plants. By increasing the size of the plant the water device can be used in a wide variety of shapes and sizes as we see in the drawings, being suitable for any type or variety of plant.

For larger plants, the water dosing device for self-irrigation can be placed inside any type of container of different materials and a single device can be used or replicated until it reaches the desired size. Another application is in an open area or a ditch in the ground we can place the water dosing device individually or in line covering more planting area.
