摘要:
A drip irrigation emitter (1), which comprises a low pressure stop filter (5), a pressure reduction channel (8), and a diaphragm (10), is disposed on the inner wall surface of a flow pipe (3) through which the irrigation liquid flows. The low pressure stop filter (5) has a hydrophobic surface and prevents inflow of the irrigation liquid when the fluid pressure is lower than an established value. The pressure reduction channel (8) reduces the pressure of the irrigation liquid. The diaphragm (10) changes the degree of opening of the pressure reduction channel (8) according to the fluid pressure of the irrigation liquid. The drip irrigation emitter (1) can be manufactured at low cost as a result of being a one-piece molding. The drip irrigation device comprising the drip irrigation emitter (1) stably ejects the irrigation liquid even when the liquid pressure is low.
