The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.

[0024] like Figure 1 As shown, a dust-free lifting door device corresponding to a preferred embodiment of the utility model includes a door frame 1, a door panel 2 and a brush member 3, a pair of brush members 3 are symmetrically installed on the door frame 1, and the door panel 2 runs in the gap between the brush members 3.

[0025] Further references Figure 2 and Figure 6 The door frame 1 includes a bottom plate 10 and a pair of side plates 11 symmetrically arranged on the bottom plate 10. The side plates 11 are provided with convex strips 110. The brush member 3 is provided with a base groove 301. The convex strip 110 is matched with the base groove 301. The door panel 2 can run between the pair of brush members 3, and the pair of brush members 3 are respectively fitted with the side surfaces 21 of the door panel 2 to achieve the purpose of dust prevention.

[0026] like Figure 3As shown, the brush member 3 includes a brush base 30 and a dustproof brush 31. The dustproof brush 31 is fixed on one side of the brush base 30, and the dustproof brush 31 is in contact with the side surface 21 of the door panel 2. One side of the brush base 30 is provided with the base groove 301, and the other side is also provided with a brush groove 302. The dustproof brush 31 is partially fixed in the brush groove 302.

[0027] like Figure 4 and Figure 5 As shown, the first end 321 of the brush member 3 and the third end 111 of the side plate 11, as well as the second end 322 of the brush member 3 and the fourth end 112 of the side plate 11 are all fixedly connected by the locking member 7. In this embodiment, the first end 321 and the second end 322 of the brush member 3 are provided with a second through hole 9, the third end 111 and the fourth end 112 of the side plate 11 are provided with a first through hole 8, the fastener 7 passes through the first through hole 8 and the second through hole 9 and is locked and fixed, and the locking member 7 can be a pair of screws and nuts or other fasteners with a locking function.

[0028] like Figure 6 and Figure 7 As shown, the dust-free lifting door device also includes a motor 5 and an electric control box 6.
