The upper ends of the vertical rods 20 are connected and fixed with the lower end face of the upper shell 10; the vertical rods 20 are cut to a corresponding length determined according to the height of the opening of the door and the opening of the window; and a lower support 14 may be disposed between the lower ends of the two vertical rods 20 as required, and form, together with the support 1, a rectangular frame body.

A first roller 2 is disposed in the cavity of the upper shell 10 and above the first outlet port 18; both ends of the first roller 2 are fixed at two ends of the upper shell 10 via a rotating shaft; and the extension line of the outer edge of the first roller 2 is located in the first outlet port 18. The first roller 2 is wound with a wind screen 3; the left and right sides of the lower end of the wind screen 3 are arranged in the notches of the first guide rails 11; and the lower end of the wind screen 3 is equipped with a support part similar to a rod 15 for supporting the wind screen 3. The first support part 15 is equipped with a part of insertion ; the lower end of the wind screen 3 is inserted inside the insertion part; the two ends of the first support part 15 are also inserted inside the notches of the first guide rails 11 on both sides; the first support part 15 is equipped with a first handle 8 and when the wind shield 3 is pulled down through the first handle 8, the wind shield 3 and the first support part 15 are directed by the first guide rails 11 downwards.

A first roll 4 is disposed in the cavity of the upper shell 10 and above the first outlet 13; the two ends of the first roller 4 are fixed at two ends of the upper shell 10 via a rotating shaft; and the extension line of the outer edge of the first roller 4 is located in the first outlet port 13. The second roller 4 is wound with a filter screen 5; the left and right sides of the lower end of the filter screen 5 are arranged in the notches of the second guide rails 12; and the lower end of the filter screen 5 is provided with a second support portion similar to a rod 16 for supporting the filter screen 5. The second support portion 16 is provided with an insertion portion; the lower end of the filter screen 5 is inserted inside the insertion part; the two ends of the second support portion 16 are also inserted inside the notches of the second guide rails 12 on both sides; the second support portion 16 is equipped with a second handle 9 and when the filter screen 5 is pulled down through the second handle 9, the filter screen 5 and the second support portion 16 are directed by the second guide rails 12 downwards.

As shown in FIG. 2, the support 1 is equipped with the first brush unit 6 and the second brush unit 7 located on the outer sides below the first roll 2 and the second roll 4, the first units of brush-mops 6 being disposed on the outer edge of the first outlet orifice 18 in the longitudinal direction of the first outlet orifice 18 and the brush-brush portion of the first brush-broom units 6 partially correspond with the outer side of the wind screen 3, so that the broom portions can clean the dust absorbed on the wind screen 3 when the wind screen 3 is moving vertically; the second brush units 7 are arranged on the outer edge of the second outlet 13 in the longitudinal direction of the second outlet 13 and the brush section of the second brush units 7 partly correspond with the outer side of the filter screen 5, so that the broom portions can clean the dust and haze absorbed on the filter screen 5 when the filter screen 5 moves vertically.

As shown in Fig. 3, unlike Embodiment 1, two first brush unit 6 and two second brush unit 7 are respectively provided; the first two brush units 6 are respectively disposed outside and inside the edges of the first outlet port 18; and the second two brush units 7 are respectively disposed outside and inside the edges of the second outlet port 12; In this way, the dust and haze on the wind screen 3 and on the filter screen 5 may be better wiped.

As shown in FIG. 4, the rail walls of the first guide rails 11 and second guide rails 12 on both sides are respectively equipped with silent brush units 19, which can reduce the noise of collection and friction between the part support / wind screen 3 / filter screen 5 and guide rails. The first layer on the outside can be a metal screen to stop insects. When the conditions of haze, dust and sand get worse, a user can immediately lower the second screen dust and haze-proof. The screen on the second layer of the door or window can be pulled vertically and horizontally depending on the shape of the door and window of the customer and can be customized.

As shown in FIG. 5, the door of the present invention comprises a door frame 21 installed on the opening of the door, the support 1 is fixed on the inside of the door frame 21, where the upper shell 10 is fixed. at the upper inner end of the door frame 21 and the vertical rods 20 are fixed on the left and right sides on the inner side of the door frame 21.

As shown in FIG. 6, the door of the present invention comprises a door frame 17 installed on the door opening, the support 1 is fixed on the inside of the door frame 17, where the upper shell 10 is fixed at the upper inner end of the door frame 17 and the vertical rods 20 are fixed on the left and right sides on the inner side of the door frame 17. The filter screen 5 of the present invention is preferably a HEPA filter ( high performance filter) capable of filtering dust and haze particles of 0.1 to 0.3 μm. The filter screen 5 can be an adhering filter, a double-sided magnet can be affixed for example, more particularly the second handle 9 can be provided with a magnetic fixing unit. The magnetic fastening unit can hold window and door filtration materials tight to dust and haze. The customer can fix or remove the retaining frames from the dust and mist-proof screens for the window and door depending on the weather conditions. For the only commercially available, single-layer dry mist-resistant doors and windows, if the weather is good and there is no dust or haze, the dry-mist screen is less than the metal screen in terms of air mobility. The present invention overcomes the disadvantage of not being able to freely choose the door and window screen with a single layer of screen against insects or against haze.
