Further, the cleaning brush heads 5 on the first filter screen 1 are in one-to-one correspondence with the number of the air holes 310 on the air hole plate 31, and the cleaning in all the air holes 310 can be simply completed at one time by using the movement of the first filter screen 1 to make each cleaning brush head 5 brush down the corresponding air hole 310.

As shown in fig. 3, the second plugging frame 42 is provided with a first clamping plate 421 for clamping the other end of the first filter screen 1, and the cooperation of the first clamping plate 421 and the first plugging slot 410 plays a role in precisely limiting and fixing the first filter screen 1 inserted into the power supply housing 3, so as to keep the first filter screen 1 stable. The second plugging frame 42 may close the second plugging slot 420, so that the second plugging frame 42 covers the bottom area of the first filter screen 1.

As shown in fig. 4, similarly, the power supply housing 3 is provided with a second clamping plate 422 for clamping the other end of the second filter screen 2. The cooperation of the second clamping plate 422 and the second inserting groove 420 plays a role in accurately limiting and fixing the second filter screen 2 inserted into the power supply shell 3, and the stability of the second filter screen 2 is maintained.

Further, in order that the dust falling onto the second plug frame 42 does not fall out into the power supply when the second plug frame 42 moves, a dust collecting baffle 423 is disposed on an end of the second plug frame 42 away from the heat dissipation air hole plate 31, and the dust collecting baffle 423 extends from the second plug frame 42 toward the first plug frame 41.

In order to facilitate the user to directly take the first plug frame 41 and the second plug frame 42 out of the power supply housing 3 by hands, the first plug frame 41 and the second plug frame 42 are respectively provided with a first groove digging position 411 and a second groove digging position 424 which have a gap with the power supply housing 3.

Illustratively, a plurality of cleaning brush heads 5 are arranged in an array at equal intervals on the inner wall of the heat dissipation air hole plate 31. Therefore, when the first plug-in frame 41 is pulled, the heat dissipation air hole plate 31 and the cleaning brush head 5 on the first filter screen 1 can mutually sweep, and the cleanliness is further improved.
