The hand dryer was born to replace paper towels and has the social significance of saving resources. As the name implies, the name "thousand layer paper" is to echo the social mission of the hand dryer, and the "thousand layer" modeling elements are applied to product design. It not only echoes the shape of lasagna paper towel, but also increases the function of water droplet drying. Compared with traditional hand dryers, it reduces the parts of the water pool and eliminates the possibility of breeding bacteria and mosquitoes. The right design language allows users to produce the right visual associations. A large number of flat lines, vertical lines, planes and rectangles are used for appearance modeling. The redundant decorative modeling is canceled and boldly left blank, so that the products can reflect the correct feeling and are more suitable for public places such as hotels, airports and hospitals.
