Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, and in particular to a self-cleaning coating device for building exterior walls. Background Technology

[0002] Building facades are not only the exterior appearance of buildings, but also the first line of defense against the external environment. They are exposed to wind, sun, rain, and snow for a long time, and must also withstand the adhesion of dust and pollutants in the air and the erosion of acid rain. With the acceleration of urbanization, the height and scale of buildings continue to rise, and the aesthetics and functions of facades have an increasingly significant impact on the urban landscape and building quality. At the same time, facades also undertake important functions such as thermal insulation, sound insulation and noise reduction. Their performance is directly related to the building's energy consumption and comfort. Therefore, research on facade cleaning, maintenance and performance improvement technologies has become an important topic in the field of architecture.

[0003] With the rapid advancement of urban modernization, the aesthetics and durability of building facades have become important indicators for measuring a city's image. However, traditional building facades are exposed to complex natural environments for extended periods, making them highly susceptible to erosion from dust, oil, and acid rain pollutants. This not only affects the building's appearance but may also accelerate the aging of wall materials and shorten the building's lifespan. With technological advancements, some self-cleaning wall technologies have emerged. By installing automatic spraying and scrubbing mechanisms on the exterior walls, these devices can clean the walls on a timed or remotely controlled basis, adapting to the cleaning needs of building facades of different heights. However, existing technologies also have shortcomings. Automatic spraying and scrubbing devices face problems such as complex equipment, high installation and maintenance costs, and inefficient water resource utilization. The cleaning effect of some devices is greatly affected by the wall material and the type of dirt, making it difficult to completely remove all types of dirt. Utility Model Content
