ABSTRACT
With the rapid development of society and the continuous improvement of people’s living standards, people often use weekend holidays to travel, and public places such as airports, stations, parks, amusement parks and so on become places where people gather. At present, there are many problems in supporting facilities in many public places, such as outdated equipment, low utilization rate, insufficient humanization, etc. However, as an essential equipment in public places, the sales volume and development potential of washbasins are huge [1]. However, in public places, we often find that we spend a lot of time waiting in line to wash our hands in public places with heavy traffic, or some public places have hand washing stations but lack functions such as hand sanitizer and hand dryer, and solving these problems has become an imperative at present.
