The self-cleaning method of the present invention comprises cleaning of the dust collecting plate 33 and cleaning of the high voltage discharge electrode plate 26.
The cleaning of the dust collection plate 33 comprises the following steps:
the cleaning requirement time of the dust collection module 30 is determined by the regular cleaning period preset by the program and the real-time air purification effect of the dust collection module 30 measured by the front particulate matter sensor 82 and the rear particulate matter sensor 83, and the cleaning requirement time is sent to the conveying mechanism 5, and meanwhile, the power supply of the dust collection module 30 is cut off.
After the conveying mechanism 5 receives the conveying instruction, the travelling motor 53 is started to drive the travelling wheels 52 to rotate and move to the rear of the dust collection module 30 to be cleaned according to the position of the dust collection module 30, and the timing for stopping the travelling wheels 52 is determined by a position sensor 81 arranged on the conveying mechanism 5.
After the carrying mechanism frame 51 is aligned with the dust collecting module frame 31, the carrying mechanism 5, the carrying motor four 23D and the carrying motor two 23B in the dust collecting module 30 simultaneously operate in the forward direction to drive the carrying wheel four 22D and the carrying wheel two 22B to rotate, so that the sliding rail one 24A is pushed to move to the carrying mechanism 5 along the longitudinal direction, and the dust collecting power supply module 32 of the dust collecting module 30 automatically disengages from the circuit mechanism 7 in the moving process.
After the dust collecting module 30 moves onto the transporting mechanism 5 along with the first sliding rail 24A, the transporting mechanism 5 carries the dust collecting module 30 to return to the rear of the self-cleaning mechanism 4.
After the conveying mechanism frame 51 is aligned with the self-cleaning mechanism portion frame 41, the conveying mechanism 5, the conveying motor four 23D and the conveying motor one 23A in the self-cleaning mechanism rotate in opposite directions at the same time, and drive the conveying wheel four 22D and the conveying wheel one 22A to rotate, so that the sliding rail one 24A is pushed to move into the self-cleaning mechanism 4 along the longitudinal direction.
After the self-cleaning mechanism 4 is cleaned, the carrying mechanism, a carrying motor four 23D and a carrying motor one 23A in the self-cleaning mechanism simultaneously rotate in the forward direction to drive a carrying wheel four 22D and a carrying wheel one 22A to rotate, so that the sliding rail one 24A is pushed to move to the carrying mechanism 5 along the longitudinal direction.
After the dust collecting module 30 moves to the carrying mechanism 5 along with the first sliding rail 24A after cleaning, the carrying mechanism 5 carries the dust collecting module 30 back to the back of the original position.
After the conveying mechanism frame 51 is aligned with the dust collecting module frame 31, the conveying mechanism, the conveying motor four 23D and the conveying motor two 23B in the dust collecting module rotate reversely at the same time to drive the conveying wheel four 22D and the conveying wheel two 22B to rotate, so that the sliding rail one 24A is pushed to move to the original position of the dust collecting module 30 along the longitudinal direction, and in the process of returning to the original position, the dust collecting power supply module 32 is automatically connected with the circuit mechanism 7.
After the above steps are completed, the system supplies power to the dust collection module 30 again.

When the dust collecting module 30 to be cleaned moves from the carrying mechanism 5 to the self-cleaning mechanism 4, the scraper driving device 43 drives the scraper 42 to move along the surface of the dust collecting plate 33, and at this time, the carrying motor four 23D in the self-cleaning mechanism and the carrying mechanism drives the carrying wheel four 22D to rotate forward/backward, so that the dust collecting module 30 can move forward and backward along the longitudinal direction, and in the process, the scraper 42 can automatically scrape off the dust on the surface of the dust collecting plate 33, so that the dust falls into the bottom dust box 44.
The bottom dust collection box 44 adopts a detachable structure, so that the air purification equipment maintainers can conveniently detach, clean and replace the bottom dust collection box in the overhauling process.
The cleaning of the high-voltage discharge electrode plate 26 comprises the following steps:
the cleaning requirement time of the high-voltage discharge module 20 is determined by the regular cleaning period preset by the program and the real-time air purification effect of the high-voltage discharge module 20 measured by the front particulate matter sensor 82 and the rear particulate matter sensor 83, a conveying instruction is sent to the conveying mechanism 5, and meanwhile, the power supply of the high-voltage discharge module 20 is cut off.
After the carrying mechanism 5 receives the carrying instruction, the travelling motor 53 is started to drive the travelling wheels 52 to rotate and move to the high-voltage discharge module 20 to be cleaned according to the position of the high-voltage discharge module 20, and the timing for stopping the travelling wheels 52 is determined by a position sensor 81 arranged on the carrying mechanism 5.
After the conveying mechanism frame 51 is aligned with the high-voltage discharge module frame 21, the conveying mechanism 5, the conveying motor four 23D, the conveying motor three 23C and the conveying motor two 23B in the high-voltage discharge module 20 simultaneously operate in the forward direction to drive the conveying wheel four 22D, the conveying wheel three 22C and the conveying wheel two 22B to rotate, so that the slide rail two 24B is pushed to move to the conveying mechanism 5 along the longitudinal direction.
