[0035] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0037] The embodiments described in this specification will now be described in detail.

[0038] Reference Figures 1-4 and Figure 7 As shown, this application discloses a fan reversing device, which includes a housing 10, a fan 20, a support plate 30, a hinge 40, a handle 50, a first seal 60, an air outlet connector 70, and a second seal 80. The fan 20 is placed inside the housing 10 and fixed on the support plate 30, which is rotatably mounted on the housing 10 via the hinge 40. The user can remove the fan 20 fixed on the support plate 30 from the housing 10 by holding the handle 50 on the support plate 30 and rotating the support plate 30.

[0039] The outer casing 10 has an interconnected receiving cavity 11 and a maintenance port 12, and the fan 20 is placed inside the receiving cavity 11. The support plate 30 is sealed on the maintenance port 12, forming an integral whole with the outer wall of the outer casing 10, making the outer casing 10 more aesthetically pleasing.

[0040] The outer casing 10 includes a base plate 13 and several upright plates 14 fixed on the same side of the base plate 13. The base plate 13 and the several upright plates 14 form a receiving cavity 11. The base plate 13 is provided with a through maintenance opening 12, and the upright plates 14 are provided with air outlets 141.

[0041] In another embodiment, the maintenance port 12 is located on the upright plate 14, and the air outlet 141 is located on the base plate 13. Alternatively, both the maintenance port 12 and the air outlet 141 may be located on the base plate 13 or the upright plate 14. The specific location can be adjusted according to the usage environment and the ease of opening the tray 30, and no restrictions are imposed here.

[0042] The edge of the maintenance opening 12 is provided with a first flange structure 15 pointing into the receiving cavity 11. The first flange structure 15 includes a first vertical segment 151 extending vertically from the edge of the maintenance opening 12 into the receiving cavity 11, and a first horizontal segment 152 extending horizontally from the end of the first vertical segment 151 towards the center of the maintenance opening 12. The cross-section of the first flange structure 15 in the vertical direction is an inverted L-shape.

[0043] Please refer to the reference again. Figure 5 As shown, the support plate 30 includes a main board 31 and a limiting plate 32 extending outward from the self-mounted board 31. The main board 31 has the same dimensions as the maintenance port 12. The limiting plate 32 abuts against the outer wall of the housing 10, thereby ensuring that the fan 20 moves to the designated position.

[0044] The limiting plate 32 is provided with two bolt mounting holes 33, which are arranged symmetrically along the length of the limiting plate 32, and fix the limiting plate 32 to the outer shell 10.

[0045] The edge of the main board 31 is provided with a second flange structure 34 that cooperates with the first flange structure 15. When the first flange structure 15 and the second flange structure 34 abut against each other, it can ensure that the tray 30 is installed in place, and can significantly prevent dust, debris, foreign objects or small insects from entering the receiving cavity 11 inside the fan turning device.

[0046] The second flange structure 34 includes a second vertical segment 341 extending vertically upward from the surface of the pallet 30, and a second horizontal segment 342 extending horizontally from the end of the second vertical segment 341 toward the center of the pallet 30. The cross-section of the second flange structure 34 in the vertical direction is an inverted L-shape. The first horizontal segment 152 and the second horizontal segment 342 abut against each other.

[0047] In this embodiment, the second flange structure 34 is arranged along the two long sides and one short side of the main board 31. The short side near the air outlet connector 70 is not provided with the second flange structure 34. This can ensure the installation position of the air outlet connector 70 and avoid collision between the air outlet connector 70 and the second flange structure 34.

[0048] The hinge 40 includes a fixed arm 41 and a swing arm 42 connected to each other. The fixed arm 41 is connected to the upright plate 14, and the swing arm 42 is connected to the support plate 30. When the swing arm 42 rotates around the fixed arm 41, it drives the support plate 30 to rotate around the outer shell 10, thereby moving the fan 20 fixed on the support plate 30 out of the receiving cavity 11.

[0049] The handle 50 is mounted on the tray 30 by screws and is located on the outside of the housing 10. In this way, the handle 50 can provide a support point when the user flips the tray 30, reducing the risk of operation.

[0050] The first seal 60 is disposed between the first horizontal section 152 and the second horizontal section 342, thereby effectively preventing dust, debris, foreign objects or small insects from entering the receiving cavity 11 inside the fan reversing device. In some cases, the first seal 60 is an adhesive strip, which is bonded to the first horizontal section 152 or the second horizontal section 342.

[0051] The air vent connector 70 has an air inlet end 71 and an air outlet end 72 arranged opposite to each other. The air inlet end 71 is connected to the fan 20, and the air outlet end 72 abuts against the vertical plate 14 and communicates with the air outlet 141. In this way, the air volume in the fan 20 enters from the air inlet end 71 of the air vent connector 70, and is blown out from the air outlet end 72 and enters the room through the air outlet 141, thereby improving the air output efficiency of the fan 20.

[0052] To ensure a tight seal between the air outlet connector 70 and the upright plate 14, preventing air from the outlet 72 from entering the receiving cavity 11, or preventing indoor dust, debris, foreign objects, or small insects from entering the receiving cavity 11 inside the fan tilting device, the outlet 72 is provided with a flange 73 extending from the edge of the outlet 72 towards its center. A second sealing element 80 is disposed between the flange 73 and the upright plate 14. In some cases, the second sealing element 80 is an adhesive strip, which is bonded to the flange 73 or the upright plate 14.

[0053] Please refer to Figure 5-7 The diagram shows the process of the tray 30 moving from a closed state to a fully open state. During daily use, the user simply needs to rotate the tray 30 around the housing 10, and then move the fan 20, which is fixed to the tray 30, from the receiving cavity 11 through the maintenance port 12 into the room, thus easily cleaning and maintaining the fan 20.

[0054] This application also discloses a ventilation device, including the aforementioned fan reversing device.
