It can remove dirt and wash it away to achieve the purpose of cleaning the surface of an object. Because it uses high-pressure water to clean dirt, high-pressure cleaning is also recognized by the world as one of the most scientific, economical and environmentally friendly cleaning methods. The use of high-pressure water flow can quickly remove stains on the surface of an object, but its high-pressure characteristics also make it easy for water to leak at the connection point.

[0025] See also Figure 1-5 The utility model provides a technical solution: a special nozzle for cleaning dirt with a high-pressure pump cleaning machine, comprising a main casing 1, a plurality of fixed rods 2 are fixedly connected to the inner surface of the main casing 1, a fixed plate 3 is fixedly connected to one end of the plurality of fixed rods 2 away from the main casing 1, a limiting rod 4 is fixedly connected to the bottom of the fixing plate 3, a non-slip plate 5 is fixedly connected to the bottom of the limiting rod 4, a limiting sleeve 6 is movably sleeved on the outer surface of the limiting sleeve 6, a plurality of first axis plates 7 are fixedly connected to the outer surface of the limiting sleeve 6, a plurality of second axis plates 8 are fixedly connected to the inner surface of the main casing 1, two connecting rods 9 are rotatably connected to the outer surface of the second axis plate 8 at one end of the two connecting rods 9 away from the first axis plate 7, a tension spring 10 is movably sleeved on the outer surface of the limiting rod 4, and when water flows into the main casing 1, the limiting sleeve 6 will be pushed to move along the limiting rod 4 toward the fixing plate 3 and the fixing rod 2.

[0026] like Figure 1-5 As shown, the bottom of the tension spring 10 is fixedly connected to the top of the limiting sleeve 6, and the top of the tension spring 10 is fixedly connected to the bottom of the fixing plate 3. When there is no water flow, the tension spring 10 will also pull the limiting sleeve 6, so that the main housing 1 tends to expand outward.

[0027] like Figure 1-5 As shown, a thread groove 11 is provided on the outer surface of the main casing 1, and a plurality of stress grooves 12 are provided on the outer surface of the main casing 1. The other end of the connecting rod 9 will push the inner wall of the main casing 1 through the second shaft plate 8. The stress groove 12 provided on the outer side of the main casing 1 will cause the main casing 1 to expand outward.

[0028] like Figure 1-5 As shown, a rubber water outlet ring 13 is fixedly connected to the inner surface of the main housing 1, and a rubber ring 14 is arranged on the top of the rubber water outlet ring 13. The rubber water outlet ring 13 and the rubber ring 14 can rotate to prevent water from flowing out.

[0029] like Figure 1-5 As shown, the top of the rubber ring 14 is connected to a secondary water pipe 15 , and two bearings 16 are provided on the outer surface of the secondary water pipe 15 .

[0030] like Figure 1-5As shown, the outer surfaces of the two bearings 16 are arranged on the inner surface of the main housing 1, and the outer surface of the secondary water pipe 15 is movably sleeved with a spring 17. The bearings 16 allow the secondary water pipe 15 and the main housing 1 to rotate relatively. The spring 17 on the outer surface of the secondary water pipe 15 will, under the action of elasticity, push the rubber ring 14 and the rubber water outlet ring 13 to contact more closely to prevent water leakage during rotation.

[0031] like Figure 1-5 As shown, the top of the spring 17 is arranged on the bottom of the bearing 16 , and the bottom of the spring 17 is arranged on the top of the rubber ring 14 .

Both ends of the water distribution pipe 18 are threadedly connected with water blocking sleeves 20. Because there is an angle of 10 degrees between the nozzles 19 on both sides, the thrust during the spraying will push the secondary water pipe 15 to rotate inside the main housing 1 through the bearing 16.

[0033] Working principle: First, connect the device to the high-pressure water pipe through the threaded groove 11. When water flows into the main housing 1, it will push the limit sleeve 6 along the limit rod 4 to move toward the fixed plate 3 and the fixed rod 2. When moving, the limit sleeve 6 will drive one end of the connecting rod 9 to move through the first shaft plate 7. The anti-drop plate 5 on the limit rod 4 can prevent the limit sleeve 6 from falling off. The other end of the connecting rod 9 will push the inner wall of the main housing 1 through the second shaft plate 8. The stress groove 12 opened on the outside of the main housing 1 will make the main housing 1 expand outward, making the connection between the main housing 1 and the water pipe more stable. When there is no water flow, the tension spring 10 will also pull the limit sleeve 6, so that the main housing 1 There is a tendency to expand outward. After the water flows into the main housing 1, it will pass through the rubber water outlet ring 13 and the rubber ring 14 to the inside of the secondary water pipe 15, then flow through the water distribution pipe 18, and finally be sprayed out from the nozzle 19. The water blocking sleeves 20 on both sides of the water distribution pipe 18 will prevent the water from flowing out from both sides. Because there is an angle of 10 degrees between the nozzles 19 on both sides, the thrust during spraying will push the secondary water pipe 15 to rotate inside the main housing 1 through the bearing 16, so that the sprayed water can rotate. The spring 17 on the outer surface of the secondary water pipe 15 will, under the action of elasticity, push the rubber ring 14 and the rubber water outlet ring 13 to contact more closely to prevent water leakage during rotation.
