The filter of claim 4, further comprising a baffle, wherein the top of the baffle is hinged to the inner side wall of the rectangular frame, and the baffle is rotationally switched between: the bottom of the baffle plate is in contact with the inner bottom wall of the rectangular frame so as to block filter residues at the bottom of the first filter screen in the first filter screen, and the baffle plate is rotatably removed from the first position in the direction away from the first filter screen in the second position; and a locking mechanism is arranged between the baffle and the rectangular frame, and is assembled to lock the baffle at the station when the baffle is at any one of the first station and the second station.

6. The filter of claim 5, wherein the locking mechanism comprises a first fixed block, a second fixed block and a movable rod, the movable rod is fixedly connected to the baffle, the first fixed block and the second fixed block are both fixedly connected to the inner side wall of the first annular frame, the baffle and the first fixed block and the movable rod and the second fixed block are both of a magnetic structure which can be attracted to each other, when the baffle is at the first station, the baffle is blocked and attracted to the first fixed block, and when the baffle is at the second station, the movable rod is blocked and attracted to the second fixed block.

7. The filter of claim 6, further comprising a passive trigger mechanism disposed on the second filter cartridge, the passive trigger mechanism driving the baffle to switch from station one to station two during upward rotation of the second filter cartridge from the horizontal position to the vertical position; when the second filter box rotates downwards from the vertical state to the horizontal state, the passive trigger mechanism drives the baffle to be switched from the second station to the first station.

8. The filter according to claim 7, wherein the passive trigger mechanism comprises a swinging plate hinged to the inclined surface of the annular enclosure, and a third elastic unit disposed between the inclined surface of the annular enclosure and the swinging plate, and the third elastic unit elastically maintains a specific included angle between the swinging plate and the inclined surface of the annular enclosure and a trend of forming the specific included angle, and the specific included angle is a preset value.

9. The filter of claim 8, wherein the third elastic unit is an elastic telescopic rod, the elastic telescopic rod comprises a two-section telescopic rod and a first spring, one end of the telescopic rod is hinged to the inclined surface of the annular enclosing plate, the other end of the telescopic rod is hinged to the swinging plate, the first spring is sleeved on the telescopic rod, and two ends of the first spring are connected to two ends of the telescopic rod.

10. The filter of any one of claims 1-9, wherein the collection box comprises a neck and a box body, the top of the neck is communicated with the air channel, and the box body is detachably connected to the bottom of the neck and communicated with the neck.
