The preset voltage is a voltage value measured when dust is not attached to the filter screen, and can be measured by the processor when a new filter screen is put into use.
The cutting unit 2 is at least one conductor sheet, and the cutting surface of the conductor sheet is not parallel to the magnetic induction lines. Because the cutting surface of the conductor sheet is not parallel to the magnetic induction lines, the side induction lines can be cut in the swing process, so that the effective generation of magnetic induction current is ensured, and the processor can detect the resistance of the filter screen.
In this embodiment, the cutting unit 2 comprises at least two conductor pieces having intersecting lines intersecting the magnetic induction lines. The two conductor sheets form a preset included angle, so that the cutting surfaces of the two conductor sheets are not parallel to the direction of the magnetic induction lines at the same time.
