Each suction pipe positioning plate 307 is fixedly connected to the suction connecting pipe 304 inside it. When using this equipment, the operator tightens the support ring 104, the positioning ring 103, and the bolts to fix the fan 109. Then, the operator fills the outside of the fan 109 with the sound-insulating and vibration-damping tube 106 to reduce vibration and noise. Next, the operator places the battery 101 inside the main suction tube 1, and further secures the rear cover 2 to the battery 101 using the rear cover positioning block 204 and the rear cover positioning cavity 205. The air outlet grille 201 and the air outlet hole 108 allow air to be smoothly discharged from inside the fan 109. Finally, the operator inserts the filter tube positioning strip 401 into the filter tube positioning groove. Inside 402, the filter tube positioning strip 401 ensures its tight fit with the filter tube positioning groove 402, guaranteeing the stability of the filter tube 4. Next, the operator sequentially installs the support frame 511, the activated carbon filter layer 510, the HEPA filter 509, and the filter screen 501 inside the filter disc 5. The operator then tightens the connecting bolts 503 and simultaneously installs the filter ring 502 inside the filter disc 5. At this point, the positioning shaft 506 and the positioning spring 507 cause the positioning head 505 to insert into the positioning block 504 and simultaneously into the positioning groove 508, thereby locking the support frame 511. The operator locks the main suction pipe 1 and the dust collection pipe 3 by using the main pipe positioning block 107 and the main suction pipe positioning groove 310. The operator then inserts the suction pipe 302 into the suction positioning pipe 301. At this point, the positioning strip 308 and the suction pipe positioning groove 306 lock the suction positioning pipe 301 and the suction connecting pipe 304, facilitating the replacement of suction pipes 302 of different models and shapes. When vacuuming the tabletop of the traditional Chinese medicine pharmacy, the operator presses the switch 202, activating the fan 109. The operator then controls the suction brush 303 to press firmly against the tabletop. The fan 109 generates negative pressure, thus preventing the anti-drop plate 30 from falling. 5. Opening the tube allows dregs and dust to enter the dust collection tube 3 through the suction tube 302. Larger impurities are blocked inside the dust collection tube 3 by the suction positioning tube 301. At the same time, fine impurities are filtered by the HEPA filter 509, and odors in the air are filtered by the activated carbon filter layer 510. Clean air is then delivered to the air outlet 108 by the fan 109 and discharged through the air outlet grille 201, thus completing the dust collection work. If the operator observes a lot of dust through the dust collection tube 3, the operator can rotate the dust collection tube 3 to facilitate cleaning of the dust, the filter 501, and the replacement of the HEPA filter 509 and the activated carbon filter layer 510.

[0019] The working process of this utility model is as follows: When using this equipment, the operator tightens the support ring 104, the positioning ring 103, and the bolts to fix the fan 109. At this time, the operator fills the outside of the fan 109 with the sound insulation and vibration damping tube 106 to achieve vibration reduction and noise reduction. Then, the operator places the battery 101 inside the main suction tube 1, and further uses the rear cover positioning block 204 and the rear cover positioning cavity 205 to make the rear cover 2 and the battery 101 fit tightly. At this time, due to the function of the air outlet grille 201 and the air outlet hole 108, the air inside the fan 109 can be smoothly discharged. Then, the operator installs the filter tube... The positioning strip 401 is inserted into the positioning groove 402 of the filter tube. At this time, the positioning strip 401 ensures that it fits tightly against the positioning groove 402, thus guaranteeing the stability of the filter tube 4. Next, the operator sequentially installs the support frame 511, the activated carbon filter layer 510, the HEPA filter 509, and the filter screen 501 inside the filter disc 5. The operator then tightens the connecting bolts 503 and simultaneously installs the filter ring 502 inside the filter disc 5. At this time, due to the action of the positioning shaft 506 and the positioning spring 507, the positioning head 505 is inserted into the positioning block 504 and simultaneously into the positioning groove 5. Inside 08, the support frame 511 is locked. At this time, the operator locks the main suction pipe 1 and the dust collection pipe 3 using the main pipe positioning block 107 and the main suction pipe positioning groove 310. The operator then inserts the suction pipe 302 into the suction positioning pipe 301. Due to the action of the positioning strip 308 and the suction pipe positioning groove 306, the suction positioning pipe 301 and the suction connecting pipe 304 are locked, facilitating the replacement of suction pipes 302 of different models and shapes. When vacuuming the tabletop of the traditional Chinese medicine pharmacy, the operator presses the switch 202, causing the fan 109 to operate. The operator then controls the vacuum brush 303 to press firmly against the tabletop. The blower 109 generates negative pressure, causing the anti-fall plate 305 to open. This allows dregs and dust to enter the dust collection pipe 3 through the suction pipe 302. Larger impurities are blocked inside the dust collection pipe 3 by the suction positioning pipe 301. Simultaneously, the HEPA filter 509 filters out fine impurities, and the activated carbon filter layer 510 filters out odors from the air. The clean air is then delivered by the blower 109 to the air outlet 108 and discharged through the air grille 201, thus completing the dust collection process. If the operator observes a large amount of dust through the dust collection pipe 3, they can rotate the dust collection pipe 3 to facilitate cleaning of the dust and the filter 501.This also facilitates the replacement of the HEPA filter 509 and the activated carbon filter layer 510.
