## Background
RELATED APPLICATION(S)
The present application is a continuation of co-pending U.S. patent application Ser. No. 13/914,466, filed Jun. 10, 2013, and entitled “INJECTOR STYLE IRRIGATION SYSTEM” which is hereby incorporated by reference.


FIELD OF THE INVENTION
This invention relates to irrigation systems for delivering water to plants and soil. More particularly, this invention relates to an injector style irrigation system for delivering water to a specific area.
BACKGROUND OF THE INVENTION
Irrigation systems are used in order to artificially apply water to an area where it is needed but not necessarily present. Automated and semi-automated irrigation systems enable areas of agriculture, landscaping and planting to be watered with little effort after the system is configured to deliver a necessary amount of water at a specified time. One key to an effective system is to get as much water and nutrients to the area as possible without over watering. However, irrigation water is often lost due to evaporation and decreased contact with the desired area as the water is sprayed over a large distance. Additionally, the amount of water needed to be sprayed in order to effectively cover a large distance maybe more than the area actually requires. Placing an irrigation outlet closer to the desired point of watering enables the system to better monitor the amount of distributed water and consequently increases the efficiency of the system by reducing the amount of water lost from evaporation and over watering.
SUMMARY OF THE INVENTION
An irrigation system comprises one or more waterlines coupled to one or more watering mechanisms for watering one or more areas. The one or more watering mechanisms are fixed in place at the desired area by an adapter which removably couples the one or more watering systems in place. Water is supplied to each of the one or more watering mechanisms by traveling from the one or more waterlines and through one or more pressure compensators. The one or more pressure compensators regulate the water flow through the one or more watering mechanisms enabling the irrigation system to uniformly distribute water at a set and constant pressure value. The water is distributed by one or more valves which are used to control one or more zones of the irrigation system.
In one aspect, an irrigation system for a watering mat comprises a water line, a watering mechanism coupled to the watering line and removably coupled to an edge or surface of the watering mat, and a pressure compensator for regulating the water flow from the water line to the watering mechanism and the watering mat.

DETAILED DESCRIPTION OF THE INVENTION
In the following description, numerous details are set forth for purpose of explanation. However, one of ordinary skill in the art will realize that the invention may be practiced without the use of these specific details or with equivalent alternatives. Thus, the presently claimed invention is not intended to be limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and features described herein. Throughout the description similar components are similarly marked in order to aid comprehension.
Embodiments of the invention are directed to an irrigation system for irrigating one or more zones and/or areas. The irrigation system comprises a water line, a watering mechanism and a pressure compensator that regulates the pressure of the water from the waterline and through the watering mechanism in order to uniformly distribute water at a set and constant pressure value. A hose assembly of the watering mechanism is removably coupled into place at a point of irrigation by an adapter. When the watering mechanism is fixed in place, an emitter end of the watering mechanism distributes water across the point of watering. The water to the irrigation system is distributed by one or more valves which are used to control one or more zones of the irrigation system.
Referring to FIG. 1, an irrigation system is depicted therein. The irrigation system 100 comprises a valve 160, a waterline 110, and one or more watering mechanisms 120. The one or more watering mechanisms 120 comprise a hose assembly 130 and an adapter 140 for coupling the one or more watering mechanisms 120 at a point of watering. As shown within FIG. 1, the one or more watering mechanisms 120 are coupled to a watering mat 150 for watering one or more plants. In some embodiments, the watering mat 150 comprises a watering mat such as described in the co-owned patent application Ser. No. 13/914,454, and entitled COMPOSITE MAT FOR WATER DISTRIBUTION AND SELF-WATERING OF POTTED PLANTS, which is hereby incorporated by reference. However, the one or more watering mechanisms 120 are able to be coupled to any appropriate object and for watering an area as desired.
The water to the irrigation system is distributed by the valve 160, which controls one or more zones of the irrigation system. For example, in some embodiments, the one or more water mechanisms 120 and watering mat 150 in FIG. 1 make up one zone and water is distributed to the zone by the valve 160. However, any number of watering mechanisms, waterlines, and watering areas are able to make up a zone. In some embodiments, multiple valves are used to control multiple zones of the system. In some embodiments, the irrigation zone is determined according to the waterline and/or hose assembly diameter, flow and pressure constraints, or a desire to water multiple areas together. Particularly, by grouping the watering areas into one or more zones, areas with similar watering requirements are able to be watered at the same time and with similar flow requirements.
The pressure compensator 121 regulates the pressure of the water from the waterline 110 and through the watering mechanism 120 in order to uniformly distribute water at a set and constant pressure value. The water is distributed to the point of watering 170 by an emitter end 135 of the watering mechanism 120. In some embodiments, the emitter end 135 distributes the water at the point of watering at a constant pressure and the water spreads over the desired watering area at a constant rate and level of application. The emitter end 135 is able to spread the water over the immediate surface of the watering area or inject the water under a surface and throughout the watering area.
In some embodiments, the irrigation system 100 further comprises a controller and/or timer for controlling the system 100 and starting and stopping the watering at a specified time. In some embodiments, the system 100 comprises one or more sensors for sensing a change or characteristic of the system 100. For example, in some embodiments, the irrigation system 100 comprises one or more sensors to detect moisture content at the point of watering, soil moisture of the plants, an overflow condition within the system 100, or water pressure changes within the system 100. Additionally, in some embodiments, the irrigation system 100 comprises one or more sensors for sensing ambient or climate conditions such as temperature, humidity, precipitation, and wind.
In some embodiments, the irrigation system 100 is a fully above ground irrigation system and easily, retrofitted, adjusted, and removable. The irrigation system 100 is able to provide a maximum watering quality and watering efficiency based upon the local climate, shady or sunny microclimates within the installation and watering, or thirst requirements of the plants.

FIGS. 4A and 4B illustrate a watering mechanism for an irrigation system removably coupling at a point of watering in accordance with some embodiments.
FIG. 4A shows a watering mechanism 420 such as described above. The watering mechanism 430 comprises a hose assembly 430 and an adapter 440 for removably coupling the watering mechanism 430 at a point of watering. As shown in FIG. 4A, the watering mechanism 420 is coupled to a watering line 410. The coupling mechanism 443 of the adapter 440 is configured to removably couple with a watering mat 450, such as described above. The coupling mechanism 443 of the adapter 440 couples with the mat 450 by sliding onto and clipping to a top edge 453 and a bottom edge 451 of the mat. As shown within FIG. 4A, the adapter 440 is configured so that the coupling mechanism 443 is in a horizontal orientation.
FIG. 4B shows the watering mechanism 420 coupled to an edge of the mat 450. As described above, the coupling mechanism 443 of the adapter 440 couples with the mat 450 by sliding onto and clipping to a top edge 453 and a bottom edge 451 of the mat. When the adapter 430 is coupled to the mat 450 and with the coupling mechanism 443 in the horizontal orientation, the watering mechanism 420 is configured to distribute water to the watering mat 450 at the point of watering 470. As shown within FIG. 4B, in this configuration, the emitter end 435 is parallel with the watering mat 450. In some embodiments, the emitter end 435 is inserted under the top layer 453 of the mat 450 and distributes water throughout the center of the watering mat 450. Particularly, with the watering mechanism 420 in place, water is supplied through the waterline 410, and the pressure compensator 421 regulates the pressure from the waterline 410 so that the water is uniformly distributed and at a set and constant pressure value to the watering mat 450. In this configuration, the water is distributed parallel to and across the watering area rather than being sprayed down onto the area from above. As described above, in some embodiments, the emitter end 435 injects the water under a surface and throughout the watering area.
FIG. 5 illustrates a schematic view of an irrigation system in accordance with some embodiments. The irrigation system 500 comprises an on/off switch 580, a programmable irrigation timer 582, one or more environmental sensors 584, a controller 586, and an irrigation system operation circuit 588. The on/off switch 580, the programmable irrigation timer 582, and the one or more environmental sensors 584 send a signal to the controller 586 which processes the signal from the on/off switch 580, the programmable irrigation timer 582, and the one or more environmental sensors 584 and sends a signal to the irrigation system operation circuit 588 based on the signal from the on/off switch 580, the programmable irrigation timer 582, and the one or more environmental sensors 584. The irrigation system operation circuit 588 operates the irrigation system based upon the signal from the controller 586.
For example, in some embodiments, the on/off switch 580 sends a signal to the controller 586 that the system has been turned on. The controller 586 process the signal from the on/off switch 580 and sends a signal to the irrigation system operation circuit 588, which turns the system on. In some embodiments, the system is turned on by opening one or more valves such as described above. Particularly, in some embodiments, the on/off switch 580 is used to turn on or off one or more zones of the irrigation system. Alternatively, in some embodiments, the programmable irrigation timer 582 sends a signal to the controller 586 that it has been programmed to start the system at 5:00 am and operate the system for thirty minutes. Consequently, the controller 586 sends a signal to the irrigation system operation circuit 588 to turn the system at 5:00 am and operate the system for thirty minutes.
In further embodiments, the controller 586 receives a signal from the one or more environmental sensors 584 based upon an operating environment of the irrigation system. For example, in some embodiments, a moisture content sensor sends a signal to the controller 486 that the watering area is saturated with water and the controller 486 sends a signal to the irrigation system operation circuit 588 to stop watering. Alternatively, the moisture content sensor is able to send a signal to the controller 486 that the watering area does not have enough water and the controller 486 sends a signal to the irrigation system operation circuit 588 to start watering. Additionally, in some embodiments, a water pressure sensor or overflow sensor sends a signal to the controller 586 that the water pressure needs to be adjusted or the system should shut off if it is overflowing. Particularly, the one or more environmental sensors 584 are able to send a signal to the controller 586 to operate the system based upon any appropriate environmental condition, such as temperature, humidity, precipitation, and wind.
As will be apparent to someone of ordinary skill in the art, the irrigation system 500 is able to comprise more or less sensors and control inputs as appropriately desired.
FIG. 6 illustrates an irrigation system in accordance with some embodiments. The irrigation system 600 comprises one or more water lines 610, one or more watering mechanisms 620, and one or more adapters 630 which have coupled the one or more watering mechanisms 620 in place at a point of watering. As shown within FIG. 6, the one or more watering mechanisms 620 are coupled to one or more watering mats 650 each holding one or more potted plants 690. When the valve 660 is opened, water travels through the one or more watering lines 610 and through one or more pressure compensators 621. The one or more pressure compensators 621 regulate the water flow and the one or more watering mechanisms 620 uniformly distribute water at a set and constant pressure value to the one or more watering mats 650 enabling the one or more watering mats 650 to water the one or more potted plants 690. Particularly, the water is injected across and/or through the one or more watering mats 650 in order to water the one or more potted plants 690.
In some embodiments, the irrigation system 600 as shown in FIG. 6 comprises a single zone of an irrigation system and the irrigation system comprises multiple zones. Additionally, although the one or more watering mechanisms 620 are shown coupled to the one or more watering mats 650, the watering mechanisms 620 are able to couple to any appropriate object and for watering an area as desired. For example, in some embodiments, the one or more watering mechanisms 620 are coupled to one or more planting beds for watering the plants located within the beds.
The irrigation system is able to be set up as an automatic or semi-automatic watering system in order to save time, effort and maintenance while watering a group of plants or area. Particularly, the irrigation system delivers water from a water source through one or more waterlines and one or more pressure compensators that adjust the water pressure and flow to a desired level. The water is then distributed to the watering area by a watering mechanism that is removably coupled into place at a point of irrigation by an adapter. When the watering mechanism is fixed in place, an emitter end of the watering mechanism distributes water across and/or into the point of watering.
Advantageously, because the irrigation system delivers water directly at and across and/or into the point of watering rather than from above the watering area, less water is lost from evaporation and water loss. Additionally, because the irrigation system is able to be implemented as an above ground watering system, it is able to be set up as a removable and/or replaceable system. Further, the one or more sensors and controllers coupled to the system ensure that each zone receives the precise amount of water that is required and that the system is able to respond to positive and negative changes within the system. Accordingly, the irrigation system as described herein has many advantages.
The invention has been described in terms of specific embodiments incorporating details to facilitate the understanding of the principles of construction and operation of the invention. Such reference herein to specific embodiments and details thereof is not intended to limit the scope of the claims appended hereto. It will be apparent to those skilled in the art that modifications are able to be made in the embodiment chosen for illustration without departing from the spirit and scope of the invention. Specifically, it will be apparent that the design of the irrigation system is able to be implemented in many different styles and configurations. Further, it will be apparent to one of ordinary skill in the art that the precise structure of the device is able to be substantially varied to accommodate various styles of water sources and watering areas. Consequently, the claims should be broadly construed, consistent with the spirit and scope of the invention, and should not be limited to their exact, literal meaning.
