In the related art, air with dust is subjected to air-dust separation in a dust collector through a separator, however, when a user uses the dust collector, because a filter screen is not installed sometimes, when the user directly uses the dust collector, a large amount of dust falls into a motor and a circuit board in the dust collector, so that an electric control system fails, and the service life of the dust collector is affected.
In the embodiment of the present invention, the detection circuit 20 is additionally provided, and includes a hall switch circuit for detecting a magnetic object disposed on the filter screen, wherein the hall switch circuit cannot detect the magnetic object and control the operation circuit of the driving motor 40 to be cut off when the filter screen is not mounted on the vacuum cleaner.
