[0007] By adopting the above technical solution, after the filter and the detection chamber are fixed, the detection chamber is moved so that the card block is embedded in the card slot, and the through hole of the card block is aligned with the through hole of the card slot. At the same time, the baffle contacts the contact sensor, and the cylinder output shaft pops out and is inserted into the through holes of the card block and the card slot, thereby fixing the detection chamber and the dust conveying chamber. By pressing the switch, the cylinder output shaft retracts from the through hole, and the detection chamber and the telescopic chamber can be separated.

[0008] Preferably, it further comprises rubber pads, which are located on both sides of the clamping block and fixedly connected to the connecting block.

[0009] By adopting the above technical solution, the acting force between the first connecting block and the second connecting block is buffered to prevent the two connecting blocks from being damaged.

[0010] Preferably, magnetic sealing pads are fixedly connected to the four sides of the openings of the detection chamber and the dust conveying chamber.

[0011] By adopting the above technical solution, the contact area between the detection chamber and the dust conveying chamber is increased, and the sealing performance is improved.

[0012] Preferably, a reinforcing rod is fixedly connected between the connecting piece and the second connecting block.

[0013] By adopting the above technical solution, the connecting plate and the connecting block are fixed together by the reinforcing rod, thereby increasing the stability of both. BRIEF DESCRIPTION OF THE DRAWINGS
