, Description:TECHNICAL FIELD
[001] The present disclosure relates in general to a drip irrigation device in fluid communication to a fluid supply pipe, more particularly, the disclosure relates to an in-line drip irrigation device for controlling a discharge amount of the irrigation fluid from the fluid supply pipe.
BACKGROUND
[002] Flood and drip irrigation are two major watering methods employed for farmlands. The irrigation method is determined by a nature of crops requiring irrigation, location of the farmland, soil and climatic conditions etc., Flood irrigation is a process of directing water through a channel and the water floods the area around the crop and soaks into the soil. In other way, drip irrigation delivers water or water mixed with fertilizers to crops in a more precise and controlled manner.
[003] Drip irrigation systems typically comprise of a fluid supply pipe which is laid across a farmland, and drip irrigation devices are installed in line with the fluid supply pipe. The drip irrigation device is an important irrigation component of the drip irrigation system. The drip irrigation device, also referred to as drippers or emitters, control the flow rate of fluid being discharged, thereby reducing fluid wastage and ensures a required amount of discharge at required pressure for different variety of crops. The drip irrigation devices are placed inside the fluid supply pipe at predetermined intervals in such a way that top side of the drip irrigation device is attached to inner surface of the fluid supply pipe and an aperture is provided on the fluid supply pipe which is in communication with the drip irrigation device for discharging fluid. The fluid supply pipes are either laid directly on the soil next to the plants or buried underneath the soil.
[004] Generally, in the drip irrigation, an external power source such as an electric pump is used to supply fluid at required pressure. In certain cases, a fluid tank is installed at a height to maintain adequate pressure in the fluid supply pipe to discharge the fluid over a length of the supply pipe through the drip irrigation device by gravity.
[005] When the fluid with a certain pressure enters the drip irrigation device, it circulates through a decompression flow path inside the drip irrigation device. The pressure is reduced, and the fluid is discharged from a discharge port of the fluid supply pipe via drip irrigation device outlet. Most of the drip irrigation devices which are currently used, for example, diaphragm emitters, vortex emitters, adjustable flow emitters etc., are having many drawbacks, for example easy clogging, poor turbulence, vortex formation, jetting at the fluid discharge port which cause the drip irrigation system to fail to operate normally and become inefficient.
[006] Also, there is another problem, these conventional drip irrigation devices require at least one bar fluid pressure to operate. It is difficult to operate that drip irrigation devices in gravity feed drip irrigation systems. So, there is a need for the electric pump to supply fluid at the required pressure. Further, pumps have high operating cost and it cannot be there in areas where electricity is not available.
[007] Therefore, felt a need for developing a simple, efficient, drip irrigation device which discharges the fluid even during clogging, without jetting and suitable for low pressure gravity fed drip irrigation system.

Each fluid inlet section (130a, 130b) defines at least one fluid inlet (132) which is extending in a direction from the bottom side to the top side of the main body (110). In an embodiment, the fluid inlet (132) of each fluid inlet section (130a, 130b) is considered to be a vertical fluid inlet.
