Description

Technical Field

[0001] This utility model belongs to the technical field of high-pressure cleaners, specifically relating to a high-pressure cleaner with an adjustable nozzle. Background Technology

[0002] In industrial production and routine maintenance, high-pressure cleaners, as efficient and environmentally friendly cleaning equipment, are widely used to remove dirt, oil stains, and other impurities from various workpieces, equipment, and surfaces. Especially in automated production lines, such as automotive parts manufacturing, machining, and electronic assembly, rapid and effective spray cleaning of workpieces on conveyor rails is crucial for ensuring product quality and production efficiency. Currently, various types of high-pressure cleaners exist on the market, including specialized cleaning equipment designed for workpieces on conveyor rails. For example, existing patent CN201223865Y discloses a similar high-pressure cleaner. This equipment uses nozzles located inside the machine body and above the conveyor rail to achieve spray cleaning of the workpieces. This design meets basic cleaning needs to a certain extent, but in practical applications, it still has some obvious limitations:

[0003] Specifically, existing high-pressure washer nozzles are typically fixed in place, with their height and angle determined after the equipment is manufactured. This makes them unadjustable to meet specific rinsing needs. However, in actual production, the size, shape, material, and surface dirt distribution of different workpieces can vary significantly. This necessitates that the washer nozzles adjust their spray height and angle to achieve optimal cleaning results. Fixed nozzles clearly cannot meet these diverse cleaning requirements, leading to poor cleaning performance in some cases, requiring multiple cleaning sessions or additional auxiliary methods, increasing production costs and time. Furthermore, adjusting fixed nozzles often requires tools for disassembly and reinstallation, which is not only cumbersome but also prone to damaging the equipment, affecting its lifespan and stability. Therefore, this invention proposes a high-pressure washer with adjustable nozzles. Utility Model Content
