Example 1
A filter screen replacement prompting method, as shown in fig. 1, the prompting method includes:
step 10, determining the accumulated working time of the filter screen to be detected;
specifically, the accumulated working time can be confirmed by recording the power-on time of a product loaded with the filter screen to be detected, namely, the accumulated working time is realized by a timing module of an MCU (micro control unit) of the product, or an additionally arranged timer is triggered to work after the product is powered on, so that the service time of the filter screen to be detected is recorded.
Step 20, obtaining a working time length alarm threshold corresponding to a filter screen to be detected, wherein the filter screen to be detected corresponds to at least one working time length alarm threshold;
specifically, different types of filter screens correspond to different working time length alarm thresholds, and when a filter screen of the same type is set in different environments, different working time length alarm thresholds can also be set correspondingly, for example, in a working environment with humidity and temperature as first conditions, the threshold is a first threshold; when the humidity and the temperature are changed to the second condition, the threshold value is changed to the second threshold value. Therefore, in the application, the filter screen to be detected corresponds to at least one working duration alarm threshold.
