步骤810，计算出n个时间点的瞬时净化率d1＝M1b/M1、d2＝M2b/M2…dn＝Mnb/Mn；
步骤812，将n个时间点的瞬时净化率d1、d2、dn，与所对应的n个时间点的预设瞬时净化率g1、g2…gn进行比较；
步骤814，当d1>g1，d2>g2…dn>gn时，判定净化装置10的净化能力失效。
在该实施例中，根据记录的n个时间点的进气口1020的粉尘浓度和出气口1022的粉尘浓度计算出对应的瞬时净化率，并将瞬时净化率与所对应的预设瞬时净化率分别进行比较，当瞬时净化率均大于所对应的预设瞬时净化率时，说明净化装置10的净化能力已经大幅度衰减，因此判定净化装置10的净化能力失效，实现了通过瞬时净化率和对应的预设瞬时净化率对净化装置10的净化能力直接进行判定，判定净化能力失效的准确率高，提升了产品的市场竞争力。进一步地，由于是综合多个浓度点的差异后进行判断，使得净化装置10判定净化能力失效的准确率更高，提升了用户的使用满意度。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
