[0023] The self-rotating blades 8 are coaxially distributed with the ventilation fan 2, and the self-rotating blades 8 are inclined, so that the airflow driven by the rotation of the ventilation fan 2 is adapted to the radius of the filter screen 4 due to the self-rotating blades 8.

[0024] Specifically, Figure 1 , Figure 4 As shown, when in use, an L-shaped support frame 5 is used to stably support the connection block 6, and a ventilation fan 2 is used to realize the rotation of the self-rotating blades 8 to promote the flow rate of the airflow near the vent 3, so as to promote the heat exchange inside and outside the cabinet 1 and ensure the ventilation and heat dissipation effect;

[0025] The other end of the rotating shaft 7 passes through the outside of the filter 4 and is installed with a rotating plate 9, and a brush 10 is installed on the inner side of the rotating plate 9, and the inner side of the brush 10 abuts against the outer side of the filter 4. Grooves 11 are provided on both sides of the rotating plate 9 away from the filter 4, and plug blocks 12 are installed inside the grooves 11, and special-shaped baffles 13 are installed on the outer sides of the plug blocks 12;

[0026] Two special-shaped baffles 13 are provided, and one side of the special-shaped baffle 13 is inclined and close to the filter screen 4, and the two special-shaped baffles 13 are respectively located on both sides of the brush 10;

[0027] Specifically, Figure 1 , Figure 2 As shown, the special structure of the special-shaped baffle 13 is used to collect the dust after the brush 10 is cleaned, so as to reduce the secondary adhesion of dust to the filter 4;

[0028] And the inner side of the special-shaped baffle 13 close to the filter screen 4 is equipped with an interception rod 19;

[0029] The interception rods 19 are located on the inclined surface of the special-shaped baffle 13 and are distributed at equal intervals in the longitudinal direction. The cross section of the interception rods 19 is arc-shaped, and the surface of the interception rods 19 is plush.

[0030] Specifically, Figure 1 , Figure 2 As shown, the structure of the interception rod 19 is used to improve the adhesion of the interception rod 19 to dust, thereby improving the dust receiving effect of the special-shaped baffle 13;

[0031] The outer sides of the special-shaped baffles 13 are connected to the rotating plate 9 with a detachable mechanism;

[0032] The detachable mechanism includes two fixing blocks 14 respectively installed on the outer sides of two special-shaped baffles 13. A connecting sleeve 16 is sleeved outside the two fixing blocks 14. A connecting hole 17 is formed inside the connecting sleeve 16, and a fixing rod 15 penetrates through the inside of the connecting hole 17. One end of the fixing rod 15 is connected to the outer side of the rotating plate 9. A locking sleeve 18 is sleeved on the outer end of the fixing rod 15, and the inner side of the locking sleeve 18 abuts against the outer side of the connecting sleeve 16;

[0033] The fixing block 14 is located on the horizontal central axis of the special-shaped baffle 13. The two fixing blocks 14 are respectively on both sides of the fixing rod 15. The distance between the outer walls of the two fixing blocks 14 is adapted to the inner length of the connecting sleeve 16;

[0036] Working principle: When the present utility model is in use, first, the ventilation fan 2 is started to blow air towards the ventilation opening 3, so that the heat inside the cabinet 1 is transferred towards the ventilation opening 3, and the internal hot air is transferred outwards through the filter screen 4;

[0037] Secondly, by the wind force of the ventilation fan 2, the self-rotating blades 8 are rotated to drive the rotating shaft 7 to rotate, so that the rotating plate 9 drives the brush 10 to rub the outer surface of the filter screen 4 to achieve a cleaning effect. By the cleaning of the brush 10 on the dust, the dust is made to fly, and then under the wind force, the dust flies outwards. Since the special-shaped baffle 13 is exactly in the direction of the flying dust, with the cooperation of the intercepting rod 19, the dust is received to prevent the secondary adhesion of the dust to the surface of the filter screen 4;

[0038] Finally, by externally screwing the locking sleeve 18, the locking sleeve 18 is separated from the fixing rod 15, and then the connecting sleeve 16 is pulled outwards, so that the connecting sleeve 16 is separated from the two fixing blocks 14, and the two special-shaped baffles 13 can be pulled out from both sides to realize the separate disassembly of 13 for the purpose of cleaning.
