摘　　要：为了解决传统除雾方法在抗击新冠肺炎疫情的过程中所出现的除雾时效短且效果不稳定等问题,该文提出一种基于氧化铟锡(Indium tin oxide,ITO)薄膜的医用护目镜加温除雾技术。该技术提出了加温除雾装置系统方案,并利用ANSYS软件模拟该除雾技术的使用环境并分析对应的温度场,获得了针对不同室温所需的除雾参数,同时以仿真结果为参考,进行了除雾效果验证试验,得到了不同环境温度下的最佳除雾温度。试验结果表明,该文提出的护目镜ITO薄膜加温除雾技术能有效延长除雾时间,且能保持除雾效果的稳定性。In the fight against the COVID-19,there are various problems in traditional defogging methods such as short defogging time and unstable defogging effects.This paper explores a new defogging mode for medical goggles which is based on heating indium tin oxide(ITO)films.According to the current status of the application,a mist removal device is designed with this technique.ANSYS is used to imitate the conditions of applying medical goggles,analyzing the temperature field of goggles,which aims to find out the suitable defogging parameters in different temperature conditions.Taking the simulation result as a reference,it carries out a demisting effect verification experiment,and gets the best defogging temperature under different ambient temperatures.The result of the experiment shows that defogging the goggles by heating ITO films works better with longer time and more stable effects.
