Design of Automatic Hand Sanitizer System Compatible with Various Containers

초록

Objectives: Demand for hand sanitizers has surged since the coronavirus broke out and spread around the world. Handsanitizers are usually applied by squirting the sanitizer liquid when one presses a pump with one’s hand. This causes manypeople to come into contact with the pump handle, which increases the risk of viral transmission. Some hand sanitizers onthe market are automatically pumped. However, because sanitizer containers and pump devices are designed to be compatibleonly between products produced by the same manufacturer, consumers must also repurchase the container for the liquidif they replace the hand sanitizer. Therefore, this paper suggests the design of an automatic hand sanitizer system compatiblewith various sanitizer containers. Methods: An automatic hand sanitizer system was designed, which will be presentedin two stages describing the instrument structure and control parts. This work focused on using the elasticity of pumps andimproving people’s access to devices. Results: We have designed an automatic hand sanitizer system that is compatible withvarious containers. When one moves one’s hand close to the device sensor, the hand sanitizer container is pumped once. Conclusions: The automatic hand sanitizer device proposed in this paper is ultimately expected to contribute to contactlesshand disinfection in public places and virus infection prevention. Additionally, it is economical and eco-friendly by decreasingwaste emissions.
