6. The electrical automation control turnover dust removal type electric appliance cabinet as claimed in claim 1, wherein the other end of the connecting shaft (9) penetrates through the side wall of the electric appliance cabinet body (1) and is connected with the handle (25) respectively, a limiting block (26) is arranged on the side wall of the electric appliance cabinet body (1), the limiting block (26) is located under the connecting shaft (9), and threaded holes matched with the fastening bolts (27) are arranged on the limiting block (26) and the connecting shaft (9) respectively.

7. The electrical automation controlled turnover dust removal type electric appliance cabinet as claimed in claim 1, wherein the working method of the electric appliance cabinet comprises the following steps:

s1, starting a turbo fan (23) and a motor in a driving mechanism, enabling outside air to enter the turnover dust removal mechanism through an air inlet cover (7) along an air inlet pipe (8) under the action of the turbo fan (23), and then filtering the outside air through a first filter screen (12) and a second filter screen (13) to remove impurities of large particles;

s2, a motor in the driving mechanism drives a driving belt pulley to rotate, the driving belt pulley drives a driven belt pulley (18) to rotate through a belt (19), the driven belt pulley (18) which rotates drives a bearing seat to rotate, so that a filter element (14) positioned on the bearing seat rotates, and therefore gas filtered by a first filter screen (12) and a second filter screen (13) is filtered through three groups of filter elements (14) which rotate continuously and small particle impurities are removed;

s3, the gas filtered by the filter element (14) sequentially enters an element chamber (3) on the electric appliance cabinet body (1) along the exhaust pipe (33) and the communicating pipe (22);

s4, when workers need to clean the turnover dust removal mechanism regularly, the fastening bolts (27) on the limiting blocks (26) are detached, then the handle (25) is rotated to drive the connecting shaft (9) to rotate, the connecting shaft (9) drives the side plates (11) and the first filter screen (12) to rotate outwards along the second filter screen (13), large-particle impurities borne on the first filter screen (12) can be cleaned, after cleaning is completed, the connecting shaft (9) is rotated, so that the side plates (11) and through holes in the side wall of the electric appliance cabinet body (1) are closed, and then the connecting shaft (9) is fixed through the fastening bolts (27);

s5, when the filter element (14) needs to be cleaned regularly, the air pipe (21) is connected with an external air tank, then a valve on the air pipe (21) is opened, so that the filter element (14) is subjected to back flushing through the air pipe (21) and the exhaust pipe (33) by gas on the air tank, and small particulate impurities on the surface of the filter element (14) can be removed.
