History air quality display method, terminal, purifier, system and medium

The invention discloses a history air quality display method. The history air quality display method comprises the following steps: a mobile terminal receives an inquiry instruction, and obtains history air quality data corresponding to the inquiry instruction under the environment of a purifier; and a graph is generated according to the history air quality data for displaying. The invention further discloses the mobile terminal, the purifier, a history air quality display system and a computer readable storage medium. The technical problems of a traditional purifier incapable of achieving thepurifying effect of the purifier and incapable of enabling users to master long-time history air quality data in their own environments are solved. 本发明公开了种历史空气质量显示方法，所述历史空气质量显示方法包括以下步骤：移动终端接收查询指令，并获取净化器所处环境下的与所述查询指令对应的历史空气质量数据；根据所述历史空气质量数据，生成曲线图并进行显示。本发明还公开了种移动终端、净化器、历史空气质量显示系统和计算机可读存储介质。本发明可以解决现有净化器，既不能体现净化器的净化效果，也无法使用户对自己所处环境的长期历史空气质量数据有所了解的技术问题。
