The filter screen has a blocking and filtering effect to prevent the debris from being extracted into the exhaust fan. The filter screen is easy to disassemble and clean;

[0020] When the dual-axis motor is started and the sliding plate moves forward or backward, it will squeeze multiple tooth blocks through the extrusion block, driving the lifting plate to move up and down repeatedly, and then the movable rod can be pulled back and forth through the connecting piece, and then the filter can be repeatedly knocked on by the knocking ball to achieve the effect of using the knocking ball to repeatedly knock on the filter, avoiding the problem of poor debris extraction effect caused by filter clogging during vacuuming, and the filter can be knocked on in time to prevent blocking.
