When the movable mounting tube slides downward, the circular mounting shaft rotates under the action of the two circular drive rods and the two spiral grooves. In addition, when the circular mounting shaft rotates under the action of the two circular driving rods and the two spiral grooves, a circle of cleaning scrapers can automatically scrape the particles on the circle of metal filter, causing the particles to fall to the lower half of the conical collecting frame, ensuring that the upper half of the circle of metal filter is in a relatively clean state, thereby ensuring the normal flow of flue gas; when the cleaning of a circle of metal filter is completed, the resistance of the flue gas passing through the circle of metal filter returns to normal, and at this time, the movable mounting tube automatically resets upward under the action of a circle of reset spring A.

The positioning mounting rod B506 is fixedly mounted on the rectangular mounting frame 501, and two return springs C507 are sleeved on the outside of the two return mounting rods B506, and the two return springs C507 are located on the right side of the movable mounting seat 502. When the staff releases the movable mounting seat 502, the movable mounting seat 502 automatically resets to the rectangular mounting frame 501 under the action of the two return springs C507; wherein, the staff can fix the baffles on the front and back sides of the rectangular mounting frame 501 respectively to prevent unfiltered smoke from being discharged through the holes on the rectangular mounting frame 501.

When the connecting assembly frame 201 is completely removed or the connecting assembly frame 201 is installed in place, the two elastic connecting rods 302 can automatically reset under the action of the two reset springs B304. When the staff starts the motor 103, they need to pull the movable mounting seat 502 to the right first. When the movable mounting seat 502 moves to the right, the control switch A504 is separated from the rectangular mounting frame 501; at the same time, the left end of the circular limiting rod 503 is separated from the limiting circular hole 2031. When there are more particles in the conical collecting rack 401, the total weight of the movable mounting part 200, the pretreatment part 400 and the particles is greater than the elastic limiting force of the two elastic connecting rods 302, so that the connecting assembly frame 201 is connected to the stove. The tube 101 can be separated automatically; when there is less particulate matter in the conical collecting rack 401, the total weight of the movable mounting portion 200, the pretreatment portion 400 and the particulate matter is less than the elastic limiting force of the two elastic connecting rods 302, and the connecting assembly rack 201 and the stove connecting pipe 101 cannot be automatically separated, realizing automatic detection of the weight of particulate matter before the equipment is used, and can prompt the staff to automatically clean the particulate matter, avoiding the equipment from shutting down due to a large amount of particulate matter after operation; when a circle of metal filter mesh 402 is seriously clogged, the resistance of the flue gas passing through the circle of metal filter mesh 402 becomes greater; when the resistance of the flue gas passing through the circle of metal filter mesh 402 becomes greater, the movable mounting tube 206 slides downward, causing a circle of return spring A208 to be compressed to a certain extent; when the movable mounting tube 206 slides downward, the circular mounting shaft 403 can rotate under the action of the two circular driving rods 202 and the two spiral grooves 4031; when the circular mounting shaft 403 is under the action of the two circular driving rods 202 and the two spiral grooves 4031 When rotating, the cleaning scrapers 406 can automatically scrape particles on the metal filter 402, causing the particles to fall to the lower half of the conical collection frame 401, ensuring that the upper half of the metal filter 402 is in a relatively clean state, thereby ensuring the normal flow of smoke. When the metal filter 402 is cleaned, the resistance of the smoke passing through the metal filter 402 returns to normal. At this time, the movable mounting tube 206 automatically returns to its normal position under the action of the return spring A208. When the staff turns off the motor 103, the staff does not need to pull out the movable mounting seat 502 completely. When the control switch B505 is separated from the rectangular mounting frame 501, the left end of the circular limit rod 503 is still inserted into the limit circular hole 2031 to ensure that the connecting combination frame 201 will not fall; when the staff releases the movable mounting seat 502, the movable mounting seat 502 automatically returns to the rectangular mounting frame 501 under the action of the two reset springs C507.
