DETAILED DESCRIPTION
(17) The present subject matter discloses an emitter configured to allow for low flow rate of water in a drip irrigation system.
(18) In the proposed invention, the echelon shaped teeth allows the emitter to better disrupt the flow of fluid, thus creating more vectors in the flow-path which results in a lower flow when compared to the same emitter using the typical straight tooth design.
(19) In addition to lower flow, the echelon shaped teeth enables opening up the flow path by raising the ceiling and creating more distance between teeth. This provides the advantages of reducing the flow rate and a lesser chance of clogging due to the increased cross-sectional area of the flow path.
(20) Referring to FIG. 1, a perspective view of an emitter 100, in accordance with an embodiment of the present subject matter. The emitter 100 may comprise of a plurality of holes 106, running along a first edge 102 and a second edge 104 of the emitter. The plurality of holes 106 may act has additional filter for filtration of slits and/or impurities. Further, the plurality of holes 106 may run along periphery of the emitter 100. The plurality of holes may extend on entire length of the emitter 100 or at least partial length of the emitter 100, between a first side 110 and a second side 112. The emitter 100 may further comprise of an echelon shaped teeth portion 114. The echelon shaped teeth portion may run parallel to the first edge 102 and the second edge 104. Further the echelon shaped teeth portion 114 at least partially extends between the first side 110 and the second side 112. According to an exemplary embodiment creating more distance between two consecutive teeth's i.e. a gap between two consecutive teeth of the echelon teeth shaped portion may be substantial to provide increased cross-section.
