Title:
REMINDING METHOD AND SYSTEM FOR REPLACING FILTER SCREEN OF VACUUM CLEANER, AND VACUUM CLEANER
Document Type and Number:
WIPO Patent Application WO/2020/114042
Kind Code:
A1
Abstract:
A reminding method for replacing a filter screen of a vacuum cleaner. The method comprises: acquiring a rotational speed difference value of an electric motor within a set time period (S101); comparing the rotational speed difference value with a pre-set rotational speed difference threshold value according to operating parameters of a vacuum cleaner, so as to obtain a comparison result (S102); and determining, according to the comparison result, whether a user is to be reminded to replace a filter screen (S103). By using the method, a vacuum cleaner can automatically remind a user to replace a filter screen in a timely manner during use of the vacuum cleaner, thereby reducing the consumption of the electric quantity, maintaining normal use of the vacuum cleaner, and prolonging the service life of an electric motor.
