Embedded type reverse-filtering and anti-blocking irrigation emitter and trickle irrigation pipeline

The invention discloses an embedded type reverse-filtering and anti-blocking irrigation emitter and a trickle irrigation pipeline. The embedded type reverse-filtering and anti-blocking irrigation emitter comprises a first part and a second part which are mutually fixed, and a filter gauze clamped between the first part and the second part, wherein a diversion channel is arranged on the first part and/or the second part, the first part is also provided with a water outlet channel which is capable of exposing the filter gauze and enabling the filter gauze to be communicated with a water outlet in a water pipe, the part around the water outlet channel is fixed with the inner wall of the water pipe, and the filter gauge clamped between the first part and the second part is a medium between the diversion channel and the water outlet channel. The embedded type reverse-filtering and anti-blocking irrigation emitter has a simple structure, is convenient in manufacture, pavement and installation, is strong in controllability of water seepage flow speed, is small, uniform and stable in discharging flow, is little in sensitivity to water pressure change, can prevent physical blockage and chemical and biological blockage, and is wide in application range.
