[0029] Working principle: During operation, the drive motor 30 is started, driving the transmission shaft 2 to rotate the connecting shaft 5 and the first gear 7 through the meshing of the worm 4 and worm wheel 6.

The pipe cover 16 is then replaced, allowing the lubricating oil to fall into the processing tank 18 through the oil drain hole 17 and through hole 19. After filtration, the oil is stored at the bottom of the processing tank 18. Then, the circulation pump 22 is started, using the feed pipe 23 to pump the lubricating oil from the processing tank 18... The internal lubricating oil is absorbed and then sprayed out through the infusion pipe 24 and the mist nozzle 25, thereby achieving the lubricating oil spraying operation on the worm 4, worm wheel 6, first gear 7, second gear 9, and third gear 12, which reduces friction between various parts, reduces wear, and extends service life. The sprayed lubricating oil will fall into the treatment box 18 through the oil drop hole 17 and the through hole 19 for filtration and storage, so as to realize the recycling of lubricating oil and reduce waste. When the filter screen 21 needs to be cleaned, simply loosen and remove the bolt 28 to release the restriction on the filter screen 21. Then, insert the cleaned filter screen 21 into the slot 20 and screw the bolt 28 back into the first threaded hole 27 and the second threaded hole 29 to complete the installation of the cleaned filter screen 21.
