An opening 21 is provided at the bottom of one side of the filter box 8. Two cross grooves 22 are provided at the bottom of the filter box 8. The two cross grooves 22 are respectively located on both sides of the opening 21. A cross block 17 is arranged inside the cross groove 22. A collecting mechanism is arranged at the bottom of the cross block 17; during use, the fan 7 is started. The air inlet end of the fan 7 sucks in air, and the air enters the filter box 8 through the air outlet end, and then is filtered through the first filter screen 14. At the same time, under the action of the wind force, there is a certain acting force on the connecting column 12 on one side of the installation frame 13, so that the connecting column 12 has a certain acting force on the spring 11 in the same-side mounting groove 10, causing the spring 11 to deform, and the spring 11 on the other side of the installation frame 13 also deforms; when the hot air in the electrical switch cabinet is discharged from the air outlet, the fan 7 is stopped. Then, the deformed springs 11 on both sides of the installation frame 13 have a certain acting force on the installation frame 13, causing the installation frame 13 to sway back and forth in the movable groove, so that the impurities and dust on the first filter screen 14 fall into the collecting device; through the settings of the spring 11, the connecting column 12, the installation frame 13, the first filter screen 14 and the collecting box 15, it is convenient to clean the dust and impurities on the first filter screen 14, and avoid too much dust and impurities on the first filter screen 14, resulting in poor filtering effect.

[0030] In this embodiment, preferably, the collecting mechanism includes a collecting box 15. The top of the collecting box 15 is fixedly connected to the bottoms of the two cross blocks 17. A baffle 16 is arranged on the top of the collecting box 15. A handle 20 is arranged on one side of the collecting box 15; it is convenient to install the collecting box 15 below the filter box 8 to collect dust and impurities.

[0031] In this embodiment, preferably, L-shaped connecting plates 19 are fixedly connected to both sides of the handle 20. A clamping block 18 is fixedly connected to the top of the L-shaped connecting plate 19. The clamping block 18 is clamped with the cross groove 22; through the setting of the clamping block 18, the stability of the collecting box 15 is ensured during the collection period.

[0032] In this embodiment, preferably, a blower 7 is fixedly connected to the bottom of the electrical switchgear body 1, and the air inlet end of the blower 7 is communicated with the side wall of the filter box 8; it is convenient to introduce cold air into the filter box 8 and then introduce the filtered cold air into the electrical switchgear.

[0033] In this embodiment, preferably, an air outlet 3 is provided at the top of the electrical switchgear body 1, and a second filter screen is arranged inside the air outlet 3; so that the hot air is discharged from the air outlet 3.

[0034] In this embodiment, preferably, a fixing column is arranged at the top of the electrical switchgear body 1, and a top plate 2 is arranged at the top of the fixing column; it has a certain protective effect on the electrical switchgear.

[0035] In this embodiment, preferably, a plurality of placing plates 4 are arranged inside the electrical switchgear body 1, and air guiding openings 5 are formed at the tops of the plurality of placing plates 4; it is convenient to install electrical appliances on the placing plates 4.

[0036] Working principle: When in use, start the blower 7. The air inlet end of the blower 7 sucks in air, and the air enters the filter box 8 through the air outlet end, and then is filtered through the first filter screen 14. At the same time, under the action of the wind force, there is a certain acting force on the connecting column 12 on one side of the mounting frame 13, so that the connecting column 12 has a certain acting force on the spring 11 in the mounting groove 10 on the same side, causing the spring 11 to deform, and the spring 11 on the other side of the mounting frame 13 also deforms; when the hot air in the electrical switchgear is discharged from the air outlet, stop the blower 7. Then, the deformed springs 11 on both sides of the mounting frame 13 have a certain acting force on the mounting frame 13, causing the mounting frame 13 to sway back and forth in the movable groove, so that the impurities and dust on the first filter screen 14 fall into the collection box 15. Then, pull the handle 20 to pull out the collection box 15 and process the dust and impurities in the collection box 15; when reinstalling the collection box 15 on the filter box 8, align the cross block 17 with the cross groove 22 and push the cross block 17 into the cross groove 22. At the same time, the clamping block 18 clamps one end of the cross groove 22 to prevent the collection box 15 from moving.

[0037] The above is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
