It should be noted that the high-pressure water flow is ejected through the swirler 4, so as to achieve road surface cleaning operation, and the outside of the nozzle body 41 is also covered with the high-pressure water flow of the swirler 4 after pressure relief of the integration assembly 315, so as to solve the problem of soil pollution caused by sputtering of the high-pressure water flow on the road surface. Preferably, the outer circumferential surface of the nozzle body 41 is conical and has a screw groove 416. Since the exterior of the nozzle body 41 also has water flow and covers the high-pressure water flow in the swirler 4 to form a water curtain, the arrangement of the thread groove 416 can more effectively prevent the high-pressure water flow from splashing. Preferably, the inner wall of the booster duct 5 is provided with a plurality of booster cavities 51. Because the joint of the spray head generally has a corner, from the fluid mechanics, a larger turbulent flow exists at the corner, and a larger blocking effect is provided for the pressure of the fluid. In view of the above situation, the applicant proposes to add a booster pipe 5 at the input end of the swirler 4, and to open several booster cavities 51 on the inner wall of the booster pipe 5, and to make the preferred shape of the booster cavity 51 a half "drop shape", and to make the concave part of the booster cavity 51 close to the flow direction of the water flow, based on this structure, the turbulent flow generated at the corner can be reduced, thereby increasing the pressure inside the pipe, which is beneficial to obtaining a better cleaning effect under the same conditions.
In this embodiment, another preferred embodiment is: the inner wall of the adjusting component 3 is provided with a spiral groove with the same spiral direction as the spiral groove 416.
