The impeller-commutated pulse sprinkler according to claim 1, wherein the inner cross-sections of the jet pipe (2), the jet space (4), the left jet outlet (5) and the right jet outlet (6) can be rectangular or rectangular in the middle, the two sides of the jet outlet are semicircular, and the outer cross-section of the jet pipe (2) is circular.
7. The impeller-commutated pulse nozzle according to claim 1, wherein the cross sections of the main nozzle (7) and the secondary nozzle (8) are front and rear circles, and the cross section area is gradually reduced from the front end to the rear end; the sections of the main nozzle (9) and the auxiliary nozzle (10) are circular, and the main nozzle and the auxiliary nozzle are in a tapered shape from the front end to the rear end.
8. The impeller commutation pulse nozzle according to claim 2, wherein the sleeve (1-1) is circular and has a diameter of 10mm to 110mm.
9. The spraying method of the impeller-commutated pulse spray head according to any one of claims 1 to 8, comprising the steps of: pressure water flow enters the jet flow space (4) after passing through the jet pipe (2) to form jet flow, and a wall attachment effect is generated under the entrainment action of the jet flow; if the wall is attached to the right side wall surface of the jet flow space (4) firstly, reaches the right jet flow outlet (6), enters the main nozzle (7), is sprayed through the main nozzle (9) and is sprinkled on the ground; through the reversing action of the jet flow reversing device (3), jet flow is switched to the left side wall surface of the jet flow space (4), reaches the left jet flow outlet (5), enters the auxiliary spray pipe (8), is sprayed out through the auxiliary spray nozzle (10), impacts the driving device (11), drives the spray head to rotate, and sprays water flow to the ground after being scattered; the water flow is periodically sprayed alternately from the left nozzle and the right nozzle in a reciprocating manner, and the intermittent impact driving device (11) drives the spray head to rotate; when the water is sprayed out along the main nozzle (9), the water is sprayed to the middle and far ground, and when the water is sprayed out along the auxiliary nozzle (10), the water is sprayed to the near and middle ground, so that the water sprayed on the whole round surface is kept uniform.
