[0018] Preferably, the filter plate is provided with a guide plate at one end close to the collection box for guiding the fallen dust into the collection box.

[0019] By adopting the above technical solution, the setting of the guide plate guides the falling dust, so that the dust falls into the collection box, thereby facilitating the collection and processing of the dust.
