As shown in fig. 1 and 6, a guiding groove for extending the movement path of impurities in irrigation water is formed in one surface of the flexible member 6 facing the water inlet 5, the guiding groove comprises a first groove body 30 and a second groove body 31, the first groove body 30 is formed along the circumferential direction of the water delivery through hole 4, the second groove body 31 is a fold line, and one end of the second groove body 31 is communicated with the bottom of the first groove body 30.
Specifically, under the pressure of the water inlet 5 and the outward flowing action of the water delivery through hole 4, the granular impurities in the irrigation water move into the first tank body 30 along the second tank body 31, are transported from the water delivery through hole 4 to the lower part of the low step surface 32 of the water outlet assembly 2, and finally are separated from the water outlet assembly 2 from the water dripping hole 7.
According to the invention, the first tank body 30 and the second tank body 31 are arranged, so that the movement path of impurities in irrigation water is prolonged, the phenomenon that the impurities are blocked due to the fact that the water flow is fast and all the impurities are accumulated at the water delivery through hole 4 at one time is avoided, and the flow performance of the water outlet assembly 2 is improved.
