A filter screen 28 is bonded to the middle of the inner bottom wall of the collecting box 24. The suction force generated by the vacuum pump 25 when it is working can suck the dust attached to the smoke sensing part of the smoke detector into the dust bag 27 through the stainless steel vacuum head 21 and the stainless steel duct 22. At this time, the suction force will be filtered by the dust bag 27 and the filter screen 28, and the dust in the suction force will remain in the dust bag 27 and the collecting box 24.

[0021] Reference Figure 1 and Figure 5The lifting assembly 3 consists of an internal threaded cap 31, a first grip rod 32, a second grip rod 33 and a third grip rod 34. The internal threaded cap 31 is welded to the bottom end of the fixing rod 11, the top thread of the first grip rod 32 is inserted into the inside of the internal threaded cap 31, the top thread of the second grip rod 33 is inserted into the middle of the bottom end of the first grip rod 32, and the top thread of the third grip rod 34 is inserted into the middle of the bottom end of the second grip rod 33. By assembling the internal threaded cap 31, the first grip rod 32, the second grip rod 33 and the third grip rod 34 together, the fixing rod 11, the fixing ring 12 and the stainless steel vacuum head 21 can be lifted to a higher height.

[0022] Reference Figure 2 , Figure 3 and Figure 4 The connecting component 4 is composed of an external threaded ring 41, an internal threaded ring 42 and an octagonal swivel ring 43. The external threaded ring 41 is fixedly sleeved on the outer surface of the top of the collecting box 24, and the internal threaded ring 42 is welded to the bottom end of the fixing cap 23. The internal threaded ring 42 is threadedly sleeved on the outer surface of the external threaded ring 41, and the fixing cap 23 and the collecting box 24 can be assembled together, so that the top of the collecting box 24 can be fixed inside the fixing cap 23, and at the same time, the contact point between the fixing cap 23 and the collecting box 24 can be sealed to prevent air leakage. The octagonal swivel ring 43 is fixedly sleeved on the outer surface of the internal threaded ring 42, which can facilitate the rotation of the internal threaded ring 42, so that the internal threaded ring 42 is threadedly connected to the external threaded ring 41.

[0023] Reference Figure 2 , Figure 3 and Figure 4 The support assembly 5 is composed of a connecting rod 51 and a ring 52. The connecting rod 51 is welded to one side of the fixed rod 11, and the ring 52 is welded to one end of the connecting rod 51. The connecting rod 51 can connect the ring 52 and the fixed rod 11. The ring 52 is fixedly sleeved on the outer surface of the top end of the fixed cap 23, thereby supporting the fixed cap 23.

[0024] Reference Figure 1 A rechargeable battery 6 is bonded to the top of one side of the fixing rod 11, and the air pump 25 is electrically connected to the rechargeable battery 6 through the control switch 7. By controlling the control switch 7, the rechargeable battery 6 can supply power to the air pump 25, thereby enabling the air pump 25 to work.

The suction force generated when the vacuum pump 25 is working can suck the dust attached to the smoke sensing part of the smoke detector through the stainless steel vacuum head 21 and the stainless steel duct 22 into the dust bag 27. At this time, the suction force will be filtered by the dust bag 27 and the filter 28, and the dust in the suction force will remain in the dust bag 27 and the collection box 24.

[0026] After the dust extraction is completed, the internal threaded ring 42 is rotated by manually twisting the octagonal rotating ring 43 so that the internal threaded ring 42 and the external threaded ring 41 are threadedly disengaged, thereby releasing the connection between the fixing cap 23 and the collection box 24. Thereafter, the fixing cap 23 is separated from the collection box 24, and the retaining ring 26 and the dust bag 27 are taken out of the collection box 24.
