Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning equipment, specifically a high-pressure rotary sealing nozzle structure. Background Technology

[0002] The function of a high-pressure cleaning nozzle is to connect to a high-pressure water pump, so that water is sprayed out in a high-pressure form to clean the surface of objects. Due to limited space, both the car wash machine and the nozzle are designed to be small in size, making them easy to carry while still achieving a good cleaning effect. However, existing small high-pressure cleaning nozzles all have a drawback: they are mostly single-layer structures, which are relatively small and can only withstand limited pressure, making them prone to breakage and affecting their service life. Among them, a small high-pressure cleaning nozzle with application number "CN202321082408.9" uses a rotor shell, a rotating bowl, a nozzle, and a rotor water inlet support set inside the shell to allow it to rotate inside the shell, thereby reducing the impact force of water pressure and providing good protection for the entire nozzle, preventing it from breaking due to large water impacts. However, this nozzle still has some shortcomings in use: because it does not have a speed adjustment structure for the rotor shell, the high-speed rotating rotor shell drives the nozzle to rotate with it, thereby damaging the nozzle. In addition, the number of nozzles is small, the cleaning area is limited, and the cleaning efficiency cannot be improved. Utility Model Content
