DETECTION METHOD FOR STATE OF FILTERING SCREEN, APPARATUS, STORAGE MEDIUM, AND AIR PURIFIER

The present disclosure provides a detection method for determining the state of a filtering screen, an apparatus, a storage medium, and an air purifier. The detection method comprises: controlling the rotational speed of a motor to stepwise increase to multiple different target rotational speeds, first executing a first determination program at each target rotational speed, and executing a second determination program when the result of the first determination program is false; when the determination result of the first determination program executed at at least two target rotational speeds is true, determining that an air inlet is blocked; when the determination result of the second determination program executed at at least two target rotational speeds is true, determining that a filtering screen is not mounted; and when the determination result of the second determination program executed at the at least two target rotational speeds is false, determining that the filtering screen is properly mounted.
