[0007] Further, a rectangular through-hole groove is arranged through the inner wall of the dripper body, and the rectangular through-hole groove is in communication with the outer wall of one side of the dripper body.

[0008] Further, the dripper body is composed of polyethylene material.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model, through the use of mounting hole and conical flow guide plate, the user can increase the number of conical flow guide plates in the flow guide groove according to the requirements of drip irrigation, and increasing different number of conical flow guide plates can improve the filtering effect, and the sawtooth on the two side outer walls of the dripper body can effectively prevent the backflow of quicksand, and through the above operation, the dripper can effectively filter and prevent the backflow of silt.
