随着我国建筑业的飞速发展,城镇多层、高层楼房日益增多。然而,人们普遍感到擦拭门窗玻璃,既麻烦,又劳累,而且还难以擦干净。擦拭多、高层房屋的外墙窗玻璃时,十分不安全,坠落事故时有发生。国内外虽然先后发明了机械、电动、电磁式等多种单面或双面玻璃擦净器,试图解决这一难题,但不是结构复杂,价格昂贵,就是操作不方便,效果不理想,很难广泛应用。
With the rapid development of China’s construction industry, the number of multi-storey and high-rise buildings in towns has increased. However, people generally feel that wiping windows and doors is both troublesome and tiring, and it is also difficult to clean. When wiping the outer window glass of many high-rise buildings, it is very unsafe and accidents of falling occur from time to time. Although domestic and foreign companies have invented a variety of single-sided or double-sided glass wipers such as mechanical, electric, electromagnetic, etc., trying to solve this problem, but it is not a complex structure, expensive, is inconvenient operation, the effect is not ideal, it is difficult widely used.
