发明名称 Self-perforating drip irrigation device
摘要 A drip irrigation emitter having a body with internal structure for reducing fluid pressure to provide a low pressure trickle output and an inlet member providing a passage for water to the internal structure and adapted to connect the emitter to a supply hose. The inlet member has a frusto-conical barb portion integral with a neck portion that extends between the large end of the barb portion and the emitter body. A cylindrical portion extending from the small end of the barb portion, which has at least one inlet opening, is usable as a mechanical punch to enable the emitter to be attached with one simple operation to a plastic irrigation hose or lateral without prepunching holes therein.
