目的 后疫情时代下人们对健康越来越重视，明确家庭空气健康的重要性，探索守护家庭空气健康的新产品设计及方法。方法 首先从经济、社会、技术(SET)等因子入手，分析后疫情时代下产品存在的机会点;再通过市场调研收集用户对消毒产品的需求，将需求进行分层和排序，结合设计事理学理论，分析产品系统内各要素间的关系，明确产品功能使用模型，借助感性工学的理论研究内容制作样本;最后得出设计概念及模型，对设计结果进行合理性评价。结论 结合设计事理学理论与感性工学研究方法，得出后疫情时代家用空气消毒产品概念模型，其过程具有科学性和可行性。进一步完善了后疫情时代健康类产品设计的研究方法，为后续相关类产品的创新设计提供了新思路。

In view of people's attention to health in the post-epidemic era, the paper aims to clear the importance of family air health, and explore new product design and methods to protect family air health. Firstly, the opportunity points of products in the post-epidemic era are analyzed from the view of economic, social and technological (SET) factors. Then through market survey, users' demands for disinfection products are collected, and combined with human science, the system elements related to products are stratified and sorted out. The function usage model is clarified, and samples are made with the help of the theoretical research of Kansei Engineering; Finally, the design concept and model are obtained, and the rationality of the design results is evaluated. Combining with the science of human affair and Kansei Engineering research method, the conceptual model of household air disinfection products in the post-epidemic era is obtained, and the process is scientific and feasible. This research further improves the methods of health product design in the post-epidemic era, and provides new ideas for the subsequent innovative design of related products.
