Therefore, when the louver 18 is installed towards the inside of the outer side plate 9, the elastic buckle plate 19 is pressed by the outer side plate 9 and tends to be in a closed state, and the elastic buckle plate 19 is tightly pressed on the inner wall of the outer side plate 9 under the elastic action, so that the louver 18 is fixed; when the blind window 18 is to be removed, a person can press the elastic fastening plate 19 to separate the elastic fastening plate 19 from the inner wall of the outer panel 9, so that the blind window 18 can be removed from the outer panel 9.

The shutter 18 is designed to be detachable so as to facilitate the attachment and detachment of the brush felt 13 by a person and the periodic cleaning of the gauze 10 in the outer panel 9.

Referring to fig. 7, the four edges of the elastic buckle plate 19 far from the louver 18 extend out of the outer panel 9, the four edges of the elastic buckle plate 19 extending out of the outer panel 9 are integrally connected with buckle ridges 20, the buckle ridges 20 are arranged in a direction back to the elastic buckle plate 19, after the louver 18 is installed in place under the action of the elastic buckle plate 19, the buckle ridges 20 can be attached to the end wall of the outer panel 9, and the inner surface of the buckle ridges 20 is provided with the sealing gasket 21, so that the sealing gasket 21 can be tightly supported on the end wall of the outer panel 9 by the buckle ridges 20, and a sealing effect is achieved, so that the possibility that rainwater penetrates into the air supply cavity 211 from the space between the elastic buckle plate 19 and the inner wall of the outer panel 9 is reduced. The edge 20 also has the function of pressing the elastic buckle plate 19, so that the shutter 18 can be removed conveniently.

Referring to fig. 1 and 2, louvers 18 are also provided at the supply air outlet of the supply air outlet chamber 212, the discharge air inlet of the discharge air inlet chamber 221, and the discharge air outlet of the discharge air outlet chamber 222, wherein the louver 18 located at the discharge air outlet of the discharge air outlet chamber 222 is installed at the side of the gauze 10 facing the outside. The three shutters 18 are detachably connected with the door and window frame 2, and specifically, the three shutters 18 are directly mounted on the door and window frame 2 through screws. These louvers 18 serve to shield rain and also to shield foreign matters such as dust, thereby improving the cleanliness of the inner space of the window and door frame 2.

The implementation principle of this application embodiment a multi-functional intelligent plastic-steel door and window does: the blower 3 and the exhaust fan 4 work simultaneously, the blower 3 forcibly sends outdoor fresh air into the room through the air inlet 211, the air channel 21 and the air outlet 212, and the exhaust fan 4 forcibly exhausts indoor polluted air to the outside through the air inlet 221, the air channel 22 and the air outlet 222, thereby realizing indoor and outdoor forced ventilation and improving indoor air quality. When the blower 3 is in operation, under the action of forced wind pressure, the rotating blades 12 can be driven to drive the rotating rollers 11 to rotate, and then the gauze 10 connected between the outer edges of the rotating blades 12 is driven to rotate, so that mosquitoes can be driven to be prevented from approaching the air supply inlet cavity 211, and meanwhile, the effects of preventing mosquitoes and other foreign matters such as dust are achieved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
