Description

Technical Field

[0001] This utility model relates to the field of tap water technology, and in particular to a device for cleaning scale buildup on the inner wall of tap water pipes. Background Technology

[0002] Water pipes are the pipelines that supply water, mainly delivering purified water from water treatment plants to each household. Modern water pipe installations typically use in-wall installation. There are three main types of water pipes: The first type is metal pipes, such as hot-dip galvanized cast iron pipes with internal plastic lining, copper pipes, and stainless steel pipes. The second type is plastic-coated metal pipes, such as steel-plastic composite pipes and aluminum-plastic composite pipes. The third type is plastic pipes. Over time, a thick layer of scale forms on the inner wall of water pipes, which not only seriously affects the quality of the tap water but also reduces the flow rate, resulting in less water output at the user's end.

[0003] Chinese patent application CN202121364525.5 discloses a household tap water pipe inner wall cleaning device, including a base, a slide rail mounted on the top of the base, a slide rail mounted on the top of a first slider, a motor mounted above the first slider, a telescopic rod mounted on the motor output shaft, and a threaded pipe between two adjacent sets of telescopic rods. This invention uses a motor to drive the mounting block to rotate, simultaneously rotating the cleaning module, which rubs against the inner wall of the tap water pipe, easily cleaning away scale. Furthermore, by replacing the mounting block with cleaning modules of different sizes, it is convenient to change the cleaning module according to different tap water pipe sizes, enhancing the contact between the cleaning module surface and the pipe wall, thereby improving cleaning efficiency. Additionally, by moving the second slider in parallel, it is convenient to adjust for tap water pipes of different lengths. Finally, a fixing clamp secures the tap water pipe, reducing the danger of handling the pipe by hand.
