[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 and Figure 2 As shown, a ventilation mechanism for a fresh air system in an embodiment of the utility model includes a connecting plate 1, an air inlet fan 2, an air outlet fan 3, a first mounting sleeve 31 and a filter 41. The connecting plate 1 is provided with an air inlet and an air outlet. The air inlet fan 2 is installed on the inner side of the air inlet, the air outlet fan 3 is installed on the inner side of the air outlet, the first mounting sleeve 31 is provided on the outer side of the air inlet, and the filter 41 is assembled in the first mounting sleeve 31.

[0021] In this embodiment, by providing an air inlet and an air outlet on the connecting plate 1, and arranging an air inlet fan 2 and an air outlet fan 3, the air can be sucked into the room from the air inlet through the air inlet fan 2, and the air can be discharged to the outside from the air outlet through the air outlet fan 3. At the same time, a first mounting sleeve 31 is arranged outside the air inlet, and a filter net 41 is assembled in the first mounting sleeve 31, so that when the air enters the room from the air inlet, it is first filtered by the filter net 41, which can remove impurities in the air. Therefore, by arranging the first mounting sleeve 31 outside the air inlet, and arranging the filter net 41 in the first mounting sleeve 31, the air can be removed by the filter net 41 when the air is sucked into the room, so as to prevent impurities in the air from entering the air inlet fan 2 or the air outlet fan 3, so as to prevent the air inlet fan 2 and the air outlet fan 3 from being disturbed by impurities in the air, thereby ensuring the effect of the ventilation mechanism for the fresh air system, and being conducive to extending the service life of the ventilation mechanism for the fresh air system.

[0022] Alternatively, if Figure 1 and Figure 2 As shown, the connecting plate 1 is configured to be in a long strip shape, and the air inlet and the air outlet are respectively located at the left and right ends of the connecting plate 1 .

[0023] In this embodiment, by setting the connecting plate 1 to be a long strip, and setting the air inlet and the air outlet at the two ends of the connecting plate 1, and the air inlet fan 2 is set corresponding to the air inlet, and the air outlet fan 3 is set corresponding to the air outlet, the air inlet fan 2 and the air outlet fan 3 are respectively set at the left and right ends of the connecting plate 1, which can avoid interference between the air inlet fan 2 and the air outlet fan 3.

[0024] Alternatively, if Figure 2 As shown, the first mounting sleeve 31 is configured as an annular structure, the filter screen 41 is configured as a circular structure, the filter screen 41 is coaxially distributed with the first mounting sleeve 31 , and is interference fit with the inner wall of the first mounting sleeve 31 .

[0025] In this embodiment, by setting the first installation sleeve 31 as an annular structure and setting the filter screen 41 as a circular structure, the filter screen 41 can be coaxially arranged with the first installation sleeve 31 and then directly inserted into the first installation sleeve 31, and the position of the filter screen 41 in the first installation sleeve 31 can be adjusted. As a result, the filter screen 41 and the inner wall of the first installation sleeve 31 are interference-fitted, which can facilitate the assembly of the filter screen 41 into the first installation sleeve 31. At the same time, the filter screen 41 is set to be interference-fitted with the inner wall of the first installation sleeve 31, which can facilitate the disassembly and cleaning of the filter screen 41.

The filter plate 42 is located in the air inlet and has an interference fit with the inner wall of the air inlet.

[0027] In this embodiment, by setting the filter plate 42 in the air inlet, that is, the filter plate 42 is located between the air inlet fan 2 and the filter screen 41, the air sucked into the room by the air inlet fan 2 can first pass through the filter screen 41, and then pass through the filter plate 42, that is, the air is filtered twice. Therefore, by setting the filter plate 42 in the air inlet, the air can be filtered twice through the filter screen 41 and the filter plate 42, which can further reduce impurities in the air. At the same time, the filter plate 42 is set to be interference fit with the inner wall of the air inlet, so that the filter plate 42 can be easily disassembled and cleaned.

The rotation direction of the wind shield 5 is perpendicular to the axial direction of the air outlet.

[0029] In this embodiment, by arranging the second mounting sleeve 32 at the air outlet and arranging the wind shield 5 in the second mounting sleeve 32, the air outlet can be closed to prevent the indoor air from being discharged from the air outlet. At the same time, the wind shield 5 can be rotated to be connected to the second mounting sleeve 32 to open the air outlet, thereby facilitating the discharge of indoor air.

[0030] Alternatively, if Figure 1As shown, the ventilation mechanism for the fresh air system also includes a third mounting sleeve 33 and a fourth mounting sleeve 34.
