[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] Refer to Figures 1-6 , a building door and window heat insulation, energy saving and natural ventilator provided in this embodiment includes an installation frame 1. A front cover plate 2 is hinged to the front side of the installation frame 1, and an air outlet 3 is provided on the front cover plate 2. A rear cover plate 4 is provided on the rear side of the installation frame 1, and an air inlet 5 is provided on the rear cover plate 4. A first filter screen 6 is provided on the air inlet 5. An annular baffle 7 is provided inside the installation frame 1, and a second filter screen 9 is detachably installed on the baffle 7 through a positioning column 8. Connecting frames for cooperating with the door and window frames are provided at both the top and bottom of the installation frame 1.

[0027] In the present invention, the ventilator is connected to the frame of the door and window through the connecting frame. The front cover plate 2 of the installation frame 1 faces the indoor, and the rear cover plate 4 faces the outdoor. The outdoor air enters through the air inlet 5 of the rear cover plate 4, and after being roughly filtered by the first filter screen 6 at the air inlet 5, it is further finely filtered by the second filter screen 9 on the positioning column 8 of the baffle 7, so as to filter out impurities such as dust and particulate matter in the outdoor air. The filtered clean air is discharged from the air outlet 3 of the front cover plate 2. The indoor air can also be discharged from the air outlet 3 towards the air inlet 5 to achieve the purpose of ventilation and air purification.

[0028] Specifically, as Figure 2 and Figure 3 shown, the bottom of the front cover plate 2 is hinged to the mounting frame 1 through a connecting shaft 21, and a positioning assembly 23 for positioning and fixing the front cover plate 2 to the mounting frame 1 is provided at a position near the top of the front cover plate 2.

[0029] Among them, the front cover plate 2 can be turned up and down through the connecting shaft 21, so that when it is necessary to clean the filter screen in the mounting frame 1, the front cover plate 2 can be opened by using the connecting shaft 21. During daily use, the top of the front cover plate 2 is positioned and fixed to the mounting frame 1 through the positioning assembly 23 to ensure the stability of the front cover plate 2 on the mounting frame 1.

[0030] Specifically, as Figures 2-4 shown, the positioning assembly 23 includes a mounting seat 231 fixed to the rear side of the top of the front cover plate 2. A plug board 232 is movably mounted on the mounting seat 231, and a return spring 233 is provided between the plug board 232 and the inner wall of the mounting seat 231;

[0031] A positioning hole 11 matching the plug board 232 is formed in the inner wall of the mounting frame 1.

[0032] Among them, when it is necessary to open the front cover plate 2, the plug board 232 is pulled into the mounting seat 231, so that the plug board 232 compresses the return spring 233 and then contracts on the mounting seat 231, and the plug board 232 is disengaged from the positioning hole 11 of the mounting frame 1. Then the front cover plate 2 can be rotated and opened through the connecting shaft 21. When the front cover plate 2 needs to be closed, the plug board 232 is also first contracted in the mounting seat 231. After the front cover plate 2 abuts against the mounting frame 1, the plug board 232 is inserted into the positioning hole 11 under the action of the return spring 233, so as to realize the fixation of the front cover plate 2.

[0033] It should be noted that a through hole 22 is formed at a position near the top of the front cover plate 2, and a slider 234 arranged inside the through hole 22 is fixedly connected to the front side of the plug board 232. Through the slider 234, it is convenient for the operator to toggle the plug board 232, and it is convenient to toggle the slider 234 to open or close the front cover plate 2 during the opening and closing process of the front cover plate 2, which is convenient for operation.

[0034] Specifically, the front end of the positioning post 8 is provided with a nut 83 that abuts against the front side of the second filter screen 9 through a threaded end 81, and a top spring 82 is sleeved on the positioning post 8 at the position of the second filter screen 9 and the baffle 7 assembly.

[0035] Among them, when the second filter screen 9 is installed, the second filter screen 9 is inserted onto the positioning post 8, and then the nut 83 is screwed onto the threaded end 81 of the positioning post 8. At this time, the second filter screen 9 will squeeze and eject the spring 82. When the second filter screen 9 is disassembled, the nut 83 on the threaded end 81 is unscrewed, and then the second filter screen 9 is ejected under the ejection action of the ejection spring 82, which further facilitates the disassembly of the second filter screen 9.

[0036] Specifically, as Figure 2 and Figure 6 shown, the rear cover plate 4 includes a first bending section 41, and a second bending section 42 is provided at the bottom of the first bending section 41. The first bending section 41 and the second bending section 42 form a V-shaped structure.

[0037] Among them, the rear cover plate 4 formed by the first bending section 41 and the second bending section 42 bends towards the front cover plate 2. Through the bent air inlet 5, the air flow can flow along a predetermined path and direction, reducing the resistance generated during the turning process of the air flow, making the air flow pass through the ventilation duct more smoothly, and improving the ventilation efficiency of the ventilator.

[0038] It should be noted that the number of air inlets 5 is several and they are evenly arranged on the first bending section 41 along the length direction of the rear cover plate 4. The aperture of the first filter screen 6 is larger than that of the second filter screen 9. The first filter screen 6 and the second filter screen 9 respectively achieve coarse filtration and fine filtration. The first filter screen 6 is used to intercept large particulate impurities in the air. Since the air inlet 5 and the first filter screen 6 are located on the first bending section 41, after the first filter screen 6 filters out the large particulate impurities, they will fall on the second bending section 42 due to gravity and roll down from the second bending section 42, thus avoiding the accumulation of the filtered large particulate impurities on the first filter screen 6. The second filter screen 9 is used to filter fine dust, thereby improving the air quality.

[0039] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
