Example 5
The present embodiment is explained about the anti-blocking treatment of the water outlet assembly 2 in the present invention based on the above embodiments.
As shown in fig. 1 and 6, a guide groove for extending the movement distance of impurities in irrigation water is arranged on one surface of the flexible part 6 facing the water inlet 5, the guide groove comprises a first groove body 30 and a second groove body 31, the first groove body 30 is arranged along the circumferential direction of the water delivery through hole 4, and the second groove body 31 is of a broken line type and one end of the second groove body is communicated with the bottom of the first groove body 30.
Specifically, under the pressure action of the water inlet 5 and the outward flowing action of the water delivery through hole 4, the granular impurities in the irrigation water can move into the first tank body 30 along the second tank body 31, and then be transported to the lower part of the low step surface 32 of the water outlet assembly 2 from the water delivery through hole 4, and finally be separated from the water outlet assembly 2 from the water dripping hole 7.
According to the invention, the first trough body 30 and the second trough body 31 are arranged, so that the movement path of impurities in irrigation water is prolonged, the impurities are prevented from being blocked due to the fact that the impurities are accumulated at the water delivery through hole 4 all at a time because of fast water flow, and the flowing performance of the water outlet assembly 2 is improved.
