Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to an air outlet mechanism and a fan lamp. Background Art

[0002] Fan lights are a common household appliance that combines the lighting performance of an air outlet mechanism with the heat dissipation performance of a fan. Currently, some fan lights on the market use a cross-flow air duct to accelerate the airflow generated by the rotating impeller.

[0003] In the related art, the cross-flow air duct usually includes a volute, and the airflow generated when the impeller rotates is discharged between the volute and the impeller, and is sent out from the air outlet along the tangential direction of the volute.

[0004] However, in traditional fan lights, after the airflow is sent out from the air outlet, the airflow has a small impact range, resulting in poor air output effect. Summary of the Invention

[0005] In view of this, the present application provides an air outlet mechanism and a fan light, which can improve the airflow diffusion effect in the axial direction of the fan wheel. The present application specifically adopts the following technical solutions:

[0006] The present application provides an air outlet mechanism, which includes a housing, a wind wheel, a first air guide, a second air guide, and at least one swinging member;

[0007] The shell is provided with an air inlet and an air outlet, and the wind wheel, the first flow guide, the second flow guide and the at least one swinging member are located inside the shell;

[0008] The first flow guide and the second flow guide are separately arranged on opposite sides of the air outlet, and the wind wheel and the at least one swinging member are located between the first flow guide and the second flow guide;

[0009] The at least one swinging member is located on a side of the wind wheel close to the air outlet, and the at least one swinging member is rotatably connected to at least one of the first flow guide member and the second flow guide member so that the at least one swinging member can swing relative to the shell, and the swing axis direction of the swinging member intersects with the axial direction of the wind wheel.

[0010] An embodiment of the present application further provides a fan light, which includes the air outlet mechanism as described above.

[0011] The beneficial effects of the embodiments of the present application are at least:

[0012] The air outlet mechanism provided in the embodiment of the present application is configured by arranging a swinging member in the shell that can swing intersecting with the axial direction of the wind wheel. When the airflow generated by the wind wheel is guided by the first guide member to flow out of the air outlet, the swinging of the swinging member can change the direction of the airflow, causing it to diffuse along the axial direction of the wind wheel, thereby improving the airflow diffusion effect in the axial direction of the wind wheel and increasing the wind field range after the airflow flows out of the air outlet.

[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] The embodiment of the present application provides an air outlet mechanism, such as Figure 1 and Figure 3 As shown, the air outlet mechanism includes a housing 1, a wind wheel 2, a first air guide 3, a second air guide 5, and at least one swinging member 4. The housing 1 is provided with an air inlet 11 and an air outlet 131. The wind wheel 2, the first air guide 3, the second air guide 5, and the at least one swinging member 4 are located within the housing 1 and are respectively connected to the housing 1. The first air guide 3 and the second air guide 5 are separately arranged on opposite sides of the air outlet 131, with the wind wheel 2 and the at least one swinging member 4 located between the first air guide 3 and the second air guide 5. The at least one swinging member 4 is located on the side of the wind wheel 2 near the air outlet 131, and is rotatably connected to at least one of the first air guide 3 and the second air guide 5, so that the at least one swinging member 4 can swing relative to the first air guide 3 and the housing 1, with the swing axis of the swinging member 4 intersecting with the axial direction of the wind wheel 2.

[0046] The air outlet mechanism provided in the embodiment of the present application is configured by arranging an oscillating member 4 in the shell 1 that can swing intersecting with the axial direction of the wind wheel 2. When the airflow generated by the wind wheel 2 is guided by the first guide member 3 and flows out of the air outlet 131, the swing of the oscillating member 4 can change the direction of the airflow, causing it to diffuse along the axial direction of the wind wheel 2, thereby improving the airflow diffusion effect in the axial direction of the wind wheel 2 and increasing the wind field range after the airflow flows out of the air outlet 131.

[0047] In some embodiments, the length of the air outlet 131 along the axial direction of the wind wheel 2 may be substantially equal to the length of the wind wheel 2 along its axial direction, so that the airflow generated by the rotation of the wind wheel 2 can fully flow out from the air outlet 131 .

[0048] like Figure 2 As shown, the air outlet mechanism may include a plurality of swing members 4, which are spaced apart along the axial direction of the wind wheel 2. In addition, the swing axis direction of the swing member 4 may be perpendicular to the axial direction of the wind wheel 2.

[0049] In some embodiments, in the axial direction of the wind rotor 2, the projection of the plurality of swinging members 4 as a whole on a set plane may be located within the projection of the air outlet 131 on the set plane, and the set plane may be perpendicular to the opening direction K of the air outlet 131, so that the airflow diffused along the axial direction of the wind rotor 2 due to the swinging of the plurality of swinging members 4 can fully flow out through the air outlet 131. For example, the opening direction K of the air outlet 131 may be vertically downward.

[0050] The two outermost swing members 4 of the multiple swing members 4 can be respectively arranged near the opposite ends of the air outlet 131 along the length direction (or the axial direction of the wind wheel 2), and for any one of the two outermost swing members 4, the swing limit position of the swing member 4 away from the other swing member 4 can be basically flush with the end edge of the air outlet 131 adjacent to the swing member 4, so that the overall swing distance of the multiple swing members 4 can be basically equivalent to the length of the air outlet 131.

[0051] In some embodiments, the number N of the swinging members 4 satisfies the following: L / (3*H*sin(θ / 2))≤N≤L / (H*sin(θ / 2)). Here, L is the axial length of the air outlet 131 along the wind wheel 2; H is the distance between the first side of the swinging member 4 close to the wind wheel 2 and the second side close to the air outlet 131; and θ is the swing angle of the swinging member 4. Regarding the number of swinging members 4, if there are too many swinging members 4, the interval between two adjacent swinging members 4 will be shorter, which may increase the swing resistance of the swinging members 4 and affect the air outlet effect; if there are too few swinging members 4, the axial diffusion effect of the airflow will be poor, which will also affect the air outlet effect.

[0052] For example, when the length L of the air outlet 131 is 250 mm, the height H of the swing member 4 is 25 mm, and the unilateral swing angle (θ / 2) of the swing member 4 is 30°, wind speed tests are conducted for different numbers of swing members 4. Figure 4 As shown, a position with a vertical distance of 2m and a horizontal distance of 60cm from the air outlet 131 is selected as the test point P to test the wind speed. The wind speeds of the test points corresponding to different numbers of swing members 4 are shown in Table 1:

[0053] Table 1

[0054] Number of swing parts (N) 5 8 12 16 20 Wind speed at test point (m / s) 0 1.1 1 0.7 0.3

[0055] Based on Table 1 above, it can be seen that if the number of the swing members 4 is too high or too low, the final air outlet effect will be affected. In some embodiments, the number of the swing members 4 is 8-12.

[0056] In some embodiments, the swing member 4 can swing symmetrically along the axis of the wind rotor 2, that is, the swing member 4 swings symmetrically along its own swing axis, wherein the swing angle (i.e., θ / 2) on one side can range from 15° to 30°. In other words, the swing angle θ of the swing member 4 ranges from 30° to 60°. For example, the swing angle of the swing member 4 is 60°, and the swing angle on one side is 30°.

[0057] The shape and connection structure of the swing member 4 are introduced below.

[0058] like Figure 3 、 Figure 5 and Figure 6 As shown, the swing member 4 includes a blade portion 41 , a first rotating shaft 42 and a second rotating shaft 43 , wherein the first rotating shaft 42 and the second rotating shaft 43 are respectively connected to opposite sides of the blade portion 41 .

[0059] It is understood that the first rotating shaft 42 and the second rotating shaft 43 extend in opposite directions relative to the blade portion 41, so that the center axes of the first rotating shaft 42 and the second rotating shaft 43, respectively located on opposite sides of the blade portion 41, can overlap with each other, thereby limiting the swing axis of the swing member 4. In other words, the center axes of the first rotating shaft 42 and the second rotating shaft 43 are the swing axis of the swing member 4. In some embodiments, the extension direction of the first rotating shaft 42 and the second rotating shaft 43 can be perpendicular to the opening direction K of the air outlet 131.

[0060] like Figure 3 As shown, the first rotating shaft 42 can be rotatably connected to the first flow guide 3. For example, Figure 7As shown, a first rotating hole 31 is opened on the first flow guide 3, and each first rotating shaft 42 can be extended into a first rotating hole 31 and can rotate in the first rotating hole 31, thereby realizing the rotational connection between the first rotating shaft 42 and the first flow guide 3.

[0061] The second rotating shaft 43 can be rotatably connected to the housing 1. In some embodiments, Figure 3 、 Figure 8 and Figure 9 As shown, a first limiting plate 134 may be provided on the inner side of the shell 1, and the first limiting plate 134 may be located on the side of the air outlet 131 away from the first air guide member 3, and located on the side of the second air guide member 5 away from the air outlet 131; and a second rotating hole 1341 may be opened on the first limiting plate 134, and each second rotating shaft 43 may extend into a corresponding second rotating hole 1341, and can rotate in the second rotating hole 1341, thereby realizing the rotational connection between the second rotating shaft 43 and the shell 1.

[0062] For example, the first limiting plate 134 may be a retaining wall for enclosing the air outlet 131, and the first limiting plate 134 may extend toward the inside of the housing 1. Similarly, a second limiting plate 135 may be provided on the inside of the housing 1, the second limiting plate 135 being located on a side of the air outlet 131 away from the first limiting plate 134. For example, the second limiting plate 135 may be another retaining wall for enclosing the air outlet 131, and the first limiting plate 134 and the second limiting plate 135 are opposed to each other along the width direction of the air outlet 131.

[0063] In other embodiments, the second rotating shaft 43 is rotatably connected to the second flow guide 5. For example, the second flow guide 5 may be provided with a rotating hole for rotatably cooperating with the second rotating shaft 43.

[0064] like Figure 8 and Figure 9 As shown, the second flow guide member 5 can be connected to the first limiting plate 134 in an abutting manner. A second rotation hole 1341 can be defined on the first limiting plate 134 near a side edge of the second flow guide member 5. This second rotation hole 1341 can be open, and a portion of the second flow guide member 5 can overlap the first limiting plate 134 to close the opening of the second rotation hole 1341. Furthermore, the portion of the second flow guide member 5 that closes the second rotation hole 1341 can have an escape recess that cooperates with the open second rotation hole 1341 to provide space for the second rotating shaft 43 to rotate.

[0065] In some embodiments, the first flow guide 3 may be a volute, and the second flow guide 5 may be a volute tongue. The specific structures of the first flow guide 3 and the second flow guide 5 will be described in detail below and will not be repeated here.

[0066] like Figure 3 and Figure 5 As shown, the blade portion 41 is clamped between the first air guide 3 and the first limiting plate 134 (or the second air guide 5). In some embodiments, along the width direction of the air outlet 131, the orthographic projection of the air outlet 131 on a set plane is located within the orthographic projection of the blade portion 41 on the set plane. The set plane is perpendicular to the opening direction K of the air outlet 131. The width direction is the direction from the first side of the air outlet 131 to the second side, and the width direction is perpendicular to the length direction of the air outlet 131.

[0067] In some embodiments, as Figure 3 and Figure 5 As shown, the maximum distance H1 between the first side of the blade portion 41 and the swing axis of the swing member 4 is smaller than the maximum distance H2 between the second side of the blade portion 41 and the swing axis, wherein the first side is the side of the blade portion 41 close to the wind wheel 2, and the second side is the side of the blade portion 41 close to the air outlet 131. In other words, the first side can be understood as the top of the blade portion 41 facing the wind wheel 2; the second side can be understood as the end of the blade portion 41 facing the air outlet 131. Therefore, based on Figure 5 and Figure 6 As shown, the first rotating shaft 42 can be set at the top of the wind wheel 2 on the side of the blade part 41 facing the first guide member 3; the second rotating shaft 43 can be set at the top of the wind wheel 2 on the side of the blade part 41 facing the second guide member 5.

[0068] Therefore, reference Figure 3 It can be seen that the blade portion 41 protrudes toward the side close to the air outlet 131 relative to its swing axis, which is beneficial for the blade portion 41 to accelerate and redirect the airflow near the air outlet 131 to increase the impact range of the airflow after it diffuses from the air outlet 131.

[0069] Because the swinging member 4 can swing relative to the wind rotor 2 and the housing 1 where the air outlet 131 is located, a close distance between the swinging member and the aforementioned structures may cause structural interference and thus generate noise. Therefore, the minimum distance between the swinging member 4 and the wind rotor 2 and housing 1 must meet certain conditions to minimize noise generation.

[0070] In some embodiments, as Figure 3As shown, the minimum distance d1 between the blade portion 41 and the rotor 2 is not less than 0.05 times the diameter D of the rotor 2 and not greater than 0.2 times the diameter D of the rotor 2, that is, 0.05D ≤ d1 ≤ 0.2D. If the minimum distance between the blade portion 41 and the rotor 2 is too small, the rotation of the blade portion 41 and the rotor 2 may generate loud noise, affecting the user experience. If the minimum distance between the blade portion 41 and the rotor 2 is too large, the flow path that the airflow passes through before being blown out of the air outlet 131 will be longer, thereby increasing the flow path resistance, resulting in a decrease in wind speed and affecting the air output effect. In addition, when the minimum distance between the blade portion 41 and the wind wheel 2 is too large, the airflow cannot be promptly guided by the blade portion 41 when it flows from the space between the wind wheel 2 and the first guide member 3 through the wind wheel 2 toward the lower end of the blade portion 41. This may cause the airflow to flow back through the gap between the blade portion 41 and the wind wheel 2 through the side of the second guide member 5 due to the rotation of the wind wheel 2, thereby reducing the airflow volume and affecting the air output effect. The noise corresponding to different values ​​of the minimum distance between the blade portion 41 and the wind wheel 2 and the wind speed at the test point are shown in Table 2 below:

[0071] Table 2

[0072] Minimum distance between blade and rotor (d1) 0.05D 0.08D 0.12D 0.16D 0.2D Noise (dB(A)) 46.5 45.2 45.1 45.1 45 Wind speed at test point (m / s) 1.3 1.1 1 0.9 0.8

[0073] The test points for wind speed and noise can be selected as follows: Figure 4 As shown, the test point P is 2 m vertically and 60 cm horizontally away from the air outlet 131 .

[0074] Table 2 shows that a larger minimum distance between the blade portion 41 and the rotor 2 reduces noise generation, but also reduces wind speed at the test point. A smaller minimum distance between the blade portion 41 and the rotor 2 increases wind speed at the test point, but also increases noise generation. In some embodiments, considering the overall product size of the air outlet mechanism, the minimum distance between the blade portion 41 and the rotor 2 can be selected to be 0.08 times the diameter D of the rotor 2.

[0075] like Figure 3 and Figure 9 As shown, the minimum distance d2 between the blade portion 41 and the air outlet 131 is not less than 0.1 times the height of the blade portion 41 and not more than 0.3 times the height of the blade portion 41 .

[0076] The height of the blade portion 41 is the distance between the first side of the blade portion 41 near the wind wheel 2 and the second side near the air outlet 131. Similarly, if the minimum distance between the blade portion 41 and the air outlet 131 is too small, the blade portion 41 may generate a large noise when rotating relative to the air outlet 131, affecting the user experience. If the minimum distance between the blade portion 41 and the air outlet 131 is too large, a large vortex will be generated at the end of the blade portion 41 facing the air outlet 131, resulting in increased wind resistance, thereby reducing wind speed and affecting the final wind output effect. If the minimum distance between the blade portion 41 and the air outlet 131 is moderate, for example, between 0.1 and 0.3 times the height of the blade portion 41, the air outlet grille 133 at the air outlet 131 will play a role in breaking up the vortex, reducing vortex losses, and thus improving the wind output effect. Furthermore, if the minimum distance between the blade portion 41 and the air outlet 131 is too large, the airflow, after being guided by the swinging member 4, cannot be promptly delivered from the air outlet 131. This may cause the airflow to flow back through the second guide member 5 from the gap between the blade portion 41 and the air outlet 131 due to the rotation of the wind wheel 2, thereby reducing the airflow volume and affecting the air outlet effect. When the height H of the blade portion 41 is mm, the noise and wind speed corresponding to different values ​​of the minimum distance between the blade portion 41 and the air outlet 131 are shown in Table 3 below:

[0077] Table 3

[0078]

[0079] The test points for wind speed and noise can be selected as follows: Figure 4 As shown, the test point P is 2 m vertically and 60 cm horizontally away from the air outlet 131 .

[0080] Based on Table 3 above, it can be seen that the larger the minimum distance between the blade portion 41 and the air outlet 131, the less noise is generated, but the lower the wind speed at the test point. The smaller the minimum distance between the blade portion 41 and the air outlet 131, the greater the wind speed at the test point, but the greater the noise generated. In some embodiments, considering the overall product size of the air outlet mechanism, the minimum distance between the blade portion 41 and the air outlet 131 can be selected to be 5 mm, which is 0.2 times the height H of the blade portion 41. In some embodiments, the minimum distance d2 between the blade portion 41 and the air outlet 131 is not less than 3 mm, which is not less than 0.12 times the height H of the blade portion 41.

[0081] In one example, the first side and the second side of the blade portion 41 can be straight lines, and the first side and the second side are parallel to each other, so that the blade portion 41 can be formed into a rectangular plate-like structure. The height of the blade portion 41 is uniform along the extension direction of the first side and the second side.

[0082] In some embodiments, as Figure 5 and Figure 6 As shown, the first side of the blade portion 41 facing the rotor 2 may include an arcuate segment 411. This arcuate segment 411 is recessed away from the rotor 2 and is concentric with the rotor 2. The minimum distance d1 between the blade portion 41 and the rotor 2 may be the minimum distance between the rotor 2 and this arcuate segment 411. The direction of this minimum distance may, for example, be parallel to the opening direction K of the air outlet 131. By providing the blade portion 41 with an arcuate segment concentric with the rotor 2, the gap between the blade portion 41 and the rotor 2 is increased. This reduces the size of the air outlet mechanism while maintaining the minimum distance between the blade portion 41 and the rotor 2 that does not generate noise.

[0083] In this case, the height of the blade portion 41 may first decrease and then increase along the extending direction of the first side and the second side. In the case where the first side has an arc segment 411, the height of the blade portion 41 may be understood as the maximum distance between the first side and the second side along the extending direction of the first side and the second side.

[0084] In some embodiments, as Figure 3 、 Figure 8 and Figure 9 As shown, the housing 1 further includes an air outlet grille 133 disposed within the air outlet 131 for guiding and dispersing the airflow flowing out of the air outlet 131 so that the airflow can flow out evenly from the air outlet 131. The minimum distance d2 between the blade portion 41 and the air outlet 131 can be the distance between the end (second side) of the blade portion 41 facing the air outlet 131 and the top of the air outlet grille 133 (e.g., the longitudinal grille 1331 described below) on the side closest to the air outlet 131.

[0085] For example, Figure 8 and Figure 9 As shown, the air outlet grille 133 may include at least one longitudinal grille 1331 and at least one transverse grille 1332, wherein the longitudinal grille 1331 extends along the length direction of the air outlet 131, and the multiple longitudinal grilles 1331 are arranged at intervals along the width direction of the air outlet 131; the transverse grille 1332 extends along the width direction of the air outlet 131, and the multiple transverse grilles 1332 are arranged at intervals along the length direction of the air outlet 131.

[0086] The top of the longitudinal grille 1331 on the side closest to the wind rotor 2 may be curved toward the first air guide 3, thereby forming an arc-shaped longitudinal grille 1331. Each transverse grille 1332 may be connected between multiple longitudinal grilles 1331 and located on the side of the longitudinal grille 1331 away from the wind rotor 2. In some embodiments, the top of the longitudinal grille 1331 on the side closest to the wind rotor 2 may be no higher than the end of the first air guide 3 on the side closest to the air outlet 131 to avoid affecting the airflow accelerated and guided by the first air guide 3 from entering the air outlet 131.

[0087] In some embodiments, as Figure 5 、 Figure 6 and Figure 7 As shown, the swinging member 4 may also include a third rotating shaft 44, which is connected to the blade portion 41 and is offset relative to the swing axis of the swinging member 4 to the side away from the air outlet 131, and the central axis of the third rotating shaft 44 is parallel to the swing axis. The air outlet mechanism also includes a connecting member 6 and a first motor 7. The connecting member 6 is connected to the first motor 7 and is rotationally connected to the third rotating shaft 44. The first motor 7 is configured to drive the connecting member 6 to swing, so as to drive the swinging member 4 to swing around the swing axis. In other words, the third rotating shaft 44 can be used as part of the driving part in the swinging member 4 to drive the swinging member 4 to swing. And setting the third rotating shaft 44 as the driving part on the side of the swing axis away from the air outlet 131 makes it easier for the first motor 7 to drive the swinging member 4 to swing.

[0088] For example, the connecting member 6 can be a plate-shaped member extending along the axial direction of the wind wheel 2, and the plane of the plate-shaped member is perpendicular to the swing axis of the swing member 4. The multiple swing members 4 are rotatably connected to the connecting member 6 through their respective third rotating shafts 44, and the multiple swing members 4 are spaced apart. Figure 7 As shown, the first motor 7 may have a first rocker arm 71 , and the first rocker arm 71 may be rotatably connected to the connecting member 6 to drive the connecting member 6 to swing.

[0089] like Figure 10 As shown, the connecting member 6 can be provided with at least one third rotating hole 61 , the number of which is consistent with the number of the swinging members 4 , and the third rotating shaft 44 of each swinging member 4 can be respectively extended into a third rotating hole 61 and can rotate in the third rotating hole 61 .

[0090] In some embodiments, as Figure 6 and Figure 10As shown, the third rotating hole 61 may include a circular hole 611 and two strip-shaped holes 612, the strip-shaped holes 612 being connected to the circular hole 611 and being arranged oppositely on both sides of the circular hole 611. The third rotating shaft 44 may include a connected tip portion 441 and a cylindrical portion 442, wherein the cylindrical portion 442 may be adapted to extend into the third rotating hole 61 and rotate in conjunction with the third rotating hole 61. The tip portion 441 is located on a side of the blade portion 41 away from the cylindrical portion 442, and the tip portion 441 gradually narrows along the extension direction of the third rotating shaft 44 away from the blade portion 41, that is, the further away the tip portion 441 is from the blade portion 41, the smaller its radial dimension becomes, and the maximum dimension of the tip portion 441 may be greater than the outer diameter of the cylindrical portion 442 and greater than the inner diameter of the circular hole 611. When the swing member 4 and the connecting member 6 are assembled, the tip portion 441 can pass through the third rotation hole 61, allowing the cylindrical portion 442 to be rotatably located in the third rotation hole 61. The tip portion 441 can also engage with the wall surface surrounding the third rotation hole 61 in the connecting member 6 to prevent the cylindrical portion 442 from being removed from the third rotation hole 61. The two strip-shaped holes 612 formed in the third rotation hole 61 facilitate the assembly of the tip portion 441.

[0091] In some embodiments, as Figure 7 As shown, the connecting member 6 is located on the side of the first air guide 3 away from the swinging member 4. The first air guide 3 includes an arcuate avoidance hole 32. The third rotating shaft 44 passes through the avoidance hole 32 and is connected to the connecting member 6. The third rotating shaft 44 can swing within the avoidance hole 32. By arranging the first air guide 3 on the side of the first air guide 3 away from the swinging member 4, the first air guide 3 can be prevented from occupying the air duct space between the first air guide 3 and the wind wheel 2.

[0092] In this case, the avoidance hole 32 can provide swing space for the third rotating shaft 44. Furthermore, when the first rocker arm 71 is rotatably connected to the connecting member 6, the avoidance hole 32 can also provide guidance for the swing of the third rotating shaft 44, thereby limiting the swing trajectory of the swinging member 4. For example, the avoidance hole 32 for limiting the swing trajectory of the swinging member 4 can be recessed in a direction away from the first air guide member 3 and closer to the air outlet 131, forming an arc-shaped hole.

[0093] In some embodiments, as Figure 5 and Figure 6As shown, the blade portion 41 may further include a transition portion 45, which is located on a side of the blade portion 41 away from the air outlet 131 and is connected to the blade portion 41. The third rotating shaft 44 is connected to an end of the transition portion 45 away from the blade portion 41 in a bent manner. The distance d3 between the central axis of the third rotating shaft 44 and the swing axis (the central axis of the first rotating shaft 42) is not less than 0.4 times the height H of the blade portion 41 and not more than 0.7 times the height H of the blade portion 41. The height H of the blade portion 41 is the distance between the top end of the blade portion 41 facing the wind wheel 2 (the first side) and the end of the blade portion 41 facing the air outlet 131 (the second side).

[0094] The distance d3 between the center axis of the third rotating shaft 44 and the swing axis (the center axis of the first rotating shaft 42) determines the driving force arm of the third rotating shaft 44. The larger this force arm, the less effort the first motor 7 uses to drive the swing member 4. The larger the height H of the blade portion 41, the greater the resistance to the swing of the blade portion 41. Therefore, by limiting the dimensional relationship between the distance d3 between the center axis of the third rotating shaft 44 and the swing axis and the height H of the blade portion 41, it is easier for the first motor 7 to drive the swing member 4 to swing. In other words, if the distance between the center axis of the third rotating shaft 44 and the swing axis is too small, the driving resistance of the swing member 4 is large; if the distance between the center axis of the third rotating shaft 44 and the swing axis is too large, the swing member 4 is more likely to interfere with the wind wheel 2.

[0095] In some embodiments, the height H of the blade portion 41 may be equal to the sum of the maximum distance H1 between the top end (first side) of the blade portion 41 facing the wind rotor 2 and the swing axis, and the maximum distance H2 between the end (second side) of the blade portion 41 facing the air outlet 131 and the swing axis. Furthermore, the height H may be greater than the distance between the arc segment 411 and the end (second side) of the blade portion 41 facing the air outlet 131.

[0096] In some embodiments, as Figure 5 and Figure 6 As shown, the blade portion 41 can be formed into a plate-like structure to increase the contact area between the blade portion 41 and the airflow. The transition portion 45 is also formed into a plate-like structure. For example, the transition portion 45 can be integrally formed with the blade portion 41, and together they are referred to as the main body of the swing member 4. The transition portion 45 can be located on the side of the blade portion 41 where the first rotating shaft 42 is located. The first rotating shaft 42 can be located at the connection position between the transition portion 45 and the blade portion 41, and the transition portion 45 can extend obliquely relative to the blade portion 41 in a direction away from the second rotating shaft 43. The third rotating shaft 44 can be connected to the end of the transition portion 45 away from the blade portion 41 to be offset relative to the second rotating shaft 43, and further offset relative to the swing axis defined by the second rotating shaft 43.

[0097] In some embodiments, as Figure 11 As shown, the first air guide 3 can be divided into an acceleration portion 33 and an installation portion 34 according to the connection position between it and the swinging member 4, wherein a dividing line parallel to the edge of the first air guide 3 is made through the connection position between the third rotating shaft 44 in the swinging member 4 and the first air guide 3 (for example, the intersection of the central axis of the third rotating shaft 44 and the first air guide 3), and the portion of the first air guide 3 located on the side of the swinging member 4 away from the air outlet 131 is used as the acceleration portion 33; and the rest of the first air guide 3 except the acceleration portion 33 is used as the installation portion 34. Based on Figure 11 and Figure 12 As can be seen, the mounting portion 34 is connected to and opposite the swinging member 4. The dividing line can be the highest point on the side of the avoidance hole 32 away from the air outlet 131 (or the end of the first air guide 3). In other words, the dividing line can be the line connecting the highest points on the side of the avoidance holes 32 away from the air outlet 131 (or the end of the first air guide 3).

[0098] Since the swinging member 4 swings, the air flow in the air duct diffuses along the axial direction of the wind wheel 2. The swinging member 4 will affect the accelerating effect of the mounting portion 34 in the first guide member 3 on the air flow in the air duct. The acceleration of the air flow will mainly depend on the accelerating portion 33 in the first guide member 3 located on the side of the swinging member 4 away from the air outlet 131, and the size of the accelerating portion 33 will affect the amount of air entering the air duct and then flowing out of the air outlet 131.

[0099] Figure 12 A cross-sectional view of the air outlet mechanism is shown, and the cross-section is perpendicular to the axial direction of the wind wheel 2 . Figure 12 In the figure, the angle formed by the lines connecting the two opposite ends of the blade portion 41 around the circumference of the wind rotor 2 and the center of the wind rotor 2 is α; the angle formed by the lines connecting the two opposite ends of the transition portion 45 around the circumference of the wind rotor 2 and the center of the wind rotor 2 is β; the angle formed by the lines connecting the two opposite ends of the acceleration portion 33 of the first air guide member 3 located on the side of the swing member 4 away from the air outlet 131 and the center of the wind rotor 2 is γ.

[0100] In some embodiments, when determining the angle α, the angle formed by the line connecting the starting center point of the central axis of the first rotating shaft 42 and the center point (center of the circle) of the wind rotor 2, and the line connecting the starting center point of the central axis of the second rotating shaft 43 and the center point of the wind rotor 2 can be used. The starting center point of the central axis of the first rotating shaft 42 can be determined by the intersection of the first rotating shaft 42 and the blade portion 41; the starting center point of the central axis of the second rotating shaft 43 can be determined by the intersection of the second rotating shaft 43 and the blade portion 41.

[0101] Similarly, when determining the angle β, the angle formed by the line connecting the starting center point of the central axis of the second rotating shaft 43 and the center point (center of the circle) of the wind rotor 2, and the line connecting the starting center point of the central axis of the third rotating shaft 44 and the center point of the wind rotor 2 can be used. The starting center point of the central axis of the third rotating shaft 44 can be determined by the intersection position of the third rotating shaft 44 and the transition portion 45.

[0102] To ensure the air volume, Figure 12 As shown, the angle α corresponding to the blade portion 41 should be smaller than the sum of the angle β corresponding to the transition portion 45 and the angle γ corresponding to the acceleration portion 33. In one example, the angle α corresponding to the blade portion 41 is smaller than the angle γ corresponding to the acceleration portion 33.

[0103] See also Figure 12 It can be seen that in the swing member 4, the blade portion 41 and the transition portion 45 are both located in the air duct space (for example, between the first air guide 3 and the second air guide 5, or between the first air guide 3 and the first limit plate 134 located on the other side of the air outlet 131), and the transition portion 45 will also swing with the blade portion 41 to cut the airflow flowing between the wind wheel 2 and the first air guide 3. Based on this, in one example, as Figure 12 As shown, the sum of the angle α corresponding to the blade portion 41 and the angle β corresponding to the transition portion 45 is smaller than the angle γ corresponding to the acceleration portion 33 .

[0104] In other words, the first angle α1 (α1 = α + β) corresponding to the swinging member 4 is smaller than the second angle α2 (α2 = γ) corresponding to the acceleration portion 33 of the first air guide member 3, where the acceleration portion 33 is the portion of the first air guide member 3 between the connection point with the third rotating shaft 44 and the starting end, where the starting end is the end of the first air guide member 3 away from the air outlet 131. In other words, the acceleration portion 33 is the portion of the first air guide member 3 located on the side of the swinging member 4 away from the air outlet 131. The first angle is the angle formed by the line connecting the two distal ends of the blade portion 41 and the transition portion 45 on a set plane and the center of the rotor 2. The second angle is the angle formed by the line connecting the two distal ends of the acceleration portion 33 along the circumference of the rotor 2 on the set plane, where the set plane is perpendicular to the circumference of the rotor 2.

[0105] The air outlet mechanism provided in the embodiment of the present application can significantly increase the influence range of the air flow flowing out of the air outlet 131 by arranging a swinging member 4 that can swing in an axial direction intersecting with the wind wheel 2 in the housing 1. In one example, Figure 13 As shown, the wind speed is tested at a distance of 2m from the air outlet. The position where the wind speed is greater than 0.5m / s is the wind field range. Compared with the traditional air outlet mechanism without the swing member 4, the wind field range is increased from 500mm to 1200mm after the swing member 4 is added.

[0106] The first flow guide member 3 and the second flow guide member 5 are introduced below.

[0107] As mentioned above, the first flow guide 3 can be a volute, and the second flow guide 5 can be a volute tongue. Figure 2 、 Figure 3 、 Figure 8 and Figure 9 As shown, the first guide member 3 and the second guide member 5 can each extend along the axial direction of the wind wheel 2. The first guide member 3 and the second guide member 5 are arranged relative to each other to form a cross-flow air duct. The wind wheel 2 is arranged between the first guide member 3 and the second guide member 5 so as to be located within the cross-flow air duct. In order to prevent the airflow from circulating within the volute (first guide member 3), a volute tongue (second guide member 5) can be arranged at the volute's return flow at the air outlet to block the return flow and allow the airflow to be blown out from the air outlet 131. The volute (first guide member 3) can be configured as an arc (for example, using a logarithmic spiral structure), and the distance between the volute and the wind wheel 2 increases as the wind wheel 2 rotates.

[0108] In some embodiments, as Figure 3 and Figure 12 As shown, the top of the air inlet 11 (including the first sub-air inlet 121, the second sub-air inlet 132, and the third sub-air inlet 122 described below) can be higher than the starting end of the first air guide 3, and the bottom of the air inlet 11 can be higher than the ending end of the first air guide 3. In this way, when the wind wheel 2 rotates to draw air from the air inlet 11 to generate airflow, the airflow can enter between the first air guide 3 and the wind wheel 2 through the gap between the starting end of the first air guide 3 and the wind wheel 2, and flow along the first air guide 3 toward the inner side of the wind wheel 2. When the airflow flows on the inner surface of the first air guide 3, the negative pressure formed by the convergence flow causes the airflow to rotate and accelerate, and then flow out from the air outlet 131.

[0109] It is understood that "higher" and "lower" refer to the vertical direction, which can be understood as parallel to the opening direction K of the air outlet 131. The direction in which the air outlet 131 points toward the wind wheel 2 is vertically upward, and the direction in which the air outlet 131 points toward the outside of the housing 1 is vertically downward. If one structure is higher than another, it can be understood that the one structure is above the other structure; similarly, if one structure is lower than another structure, it can be understood that the one structure is below the other structure.

[0110] In some embodiments, the volute shape of the first flow guide 3 can be a logarithmic spiral. Figure 12As shown, the starting end of the first air guide 3 on the side away from the air outlet 131 may be lower than the top end of the wind rotor 2 on the side away from the air outlet 131. Furthermore, a first radial distance d4 between the starting end of the first air guide 3 and the wind rotor 2 is smaller than a second radial distance d5 between the ending end of the first air guide 3 on the side away from the air outlet 131 and the wind rotor 2. The first radial distance is the distance along the line connecting the starting end of the first air guide 3 and the center of the wind rotor 2, and the second radial distance is the distance along the line connecting the ending end of the first air guide 3 and the center of the wind rotor 2.

[0111] The gap between the starting end of the first air guide 3 and the wind wheel 2 serves as the air inlet of the air duct between the first air guide 3 and the wind wheel 2, which affects the amount of air entering the air duct. The gap between the ending end of the first air guide 3 and the wind wheel 2 serves as the air outlet of the air duct between the first air guide 3 and the wind wheel 2, which affects the amount of air flowing out of the air duct. When the size of the air inlet (the first radial distance d4) is smaller than the size of the air outlet (the second radial distance d5), the gas around the air outlet mechanism is rotated by the wind wheel 2 and is sucked into the air duct between the first air guide 3 and the wind wheel 2 from the smaller air inlet. When it flows out from the larger air outlet, the airflow in the air duct can be accelerated.

[0112] Furthermore, since the wind wheel 2 can rotate relative to the first air guide member 3 , when the gap between the wind wheel 2 and the first air guide member 3 is too small, structural interference may occur between the two, thereby causing noise.

[0113] It is understandable that the diameter of the wind rotor 2 affects the rotational wind force of the wind rotor 2, thereby affecting the ability of the wind rotor 2 to absorb air from the surrounding environment. Therefore, the size of the air inlet and outlet of the above-mentioned air duct is related to the diameter of the wind rotor 2.

[0114] In some embodiments, on a set plane perpendicular to the axial direction of the rotor 2, a first radial distance d4 between the starting end of the first air guide 3 and the rotor 2 is no less than 0.01 times the diameter D of the rotor 2 and no greater than 0.1 times the diameter D of the rotor 2, where the first radial distance is the distance along the line connecting the starting end and the center of the rotor 2. As described above, the first radial distance between the starting end of the first air guide 3 and the rotor 2 determines the minimum distance between the first air guide 3 and the rotor 2 and the size of the air inlet. If the first radial distance is too small, the first air guide 3 and the rotor 2 will generate a lot of noise when operating, and the air intake volume will be reduced, thereby affecting the final air outlet effect. If the first radial distance is too large, the overall product size of the air outlet mechanism will increase, and the acceleration effect of the air duct formed between the first air guide 3 and the rotor 2 will be weakened, thereby affecting the final air outlet effect.

[0115] Furthermore, on the aforementioned set plane, a second radial distance d5 between the terminal end of the first flow guide 3 and the rotor 2 is no less than 0.1 times the diameter D of the rotor 2 and no more than 0.5 times the diameter D of the rotor 2, where the second radial distance is the distance along a line connecting the terminal end and the center of the rotor 2. In one example, the second radial distance d5 between the terminal end of the first flow guide 3 and the rotor 2 is equal to 0.23 times the diameter D of the rotor 2, i.e., d4 = 0.23D. As mentioned above, the second radial distance between the terminal end of the first guide member 3 and the wind wheel 2 determines the size of the air outlet. If the second radial distance is too small, the air outlet volume of the air duct formed between the first guide member 3 and the wind wheel 2 will be reduced, and the too small distance may also cause the first guide member 3 and the wind wheel 2 to generate greater noise when working; if the second radial distance is too large, the overall product size of the air outlet mechanism will increase, and the acceleration effect of the air duct formed between the first guide member 3 and the wind wheel 2 will be weakened, thereby affecting the final air outlet effect.

[0116] In addition, the extension length of the first air guide 3 along the circumference of the wind wheel 2 affects the acceleration distance of the airflow in the air duct, and further affects the air volume and wind speed of the airflow flowing out from the air outlet 131. In some embodiments, Figure 12 As shown, the third angle α3 corresponding to the first air guide 3 ranges from 80° to 160°, where the third angle is the angle formed by the line connecting the starting end of the first air guide 3 away from the air outlet 131 and the ending end of the first air guide 3 close to the air outlet 131, respectively, and the center of the wind rotor 2 on a set plane perpendicular to the axial direction of the wind rotor 2. In one example, the value of the third angle α3 can be 100°.

[0117] If the angular range corresponding to the first guide member 3 is too small, it means that the extension length of the air duct formed between the first guide member 3 and the wind wheel 2 is small, so that the acceleration distance of the airflow is small, resulting in a reduction in the final air outlet effect of the air outlet mechanism; and if the angular range corresponding to the first guide member 3 is too large, the distance between the first guide member 3 and the second guide member 5 will be affected and reduced accordingly, thereby affecting the size of the air outlet 131 in the air outlet mechanism, resulting in a reduction in the final air outlet effect.

[0118] In the presence of the second air guide 5, the distance between the second air guide 5 and the first air guide 3 affects the air volume that is blown out of the air outlet 131 after the airflow is accelerated by the first air guide 3. In some embodiments, the fourth angle corresponding to the first air guide 3 and the second air guide 5 is greater than 160° and no greater than 240°, where the fourth angle α4 is the angle formed by the lines connecting the starting end of the first air guide 3 away from the air outlet 131 and the end end of the second air guide 5 near the air outlet 131, respectively, and the center of the wind wheel 2. In some embodiments, the fourth angle α4 can be equal to the sum of the angle α corresponding to the blade portion 41, the angle β corresponding to the transition portion 45, and the angle γ corresponding to the acceleration portion 33.

[0119] If the fourth angle corresponding to the first air guide member 3 and the second air guide member 5 is too large, it means that the part of the wind wheel 2 not sandwiched by the first air guide member 3 and the second air guide member 5 is correspondingly reduced. In this case, the amount of air intake generated by the rotation of the wind wheel 2 will be correspondingly reduced, resulting in a reduced wind outlet effect; and if the fourth angle corresponding to the first air guide member 3 and the second air guide member 5 is too small, then as mentioned above, the extension length of the air duct formed between the first air guide member 3 and the wind wheel 2 will be correspondingly reduced, or the size of the air outlet 131 will be correspondingly reduced, resulting in a reduced wind outlet effect.

[0120] In some embodiments, as Figure 8 and Figure 9 As shown, the first air guide 3 may have at least one first mounting protrusion 35 on a side away from the wind wheel 2; correspondingly, a first fixing protrusion 136 may be provided on the inner wall of the housing 1. The first mounting protrusion 35 may be connected to the first fixing protrusion 136 to fix the first air guide 3 to the housing. For example, the first mounting protrusion 35 and the first fixing protrusion 136 may each be provided with a corresponding assembly hole, through which a connecting member such as a bolt may be sequentially inserted through the first mounting protrusion 35 and the first fixing protrusion 136 to securely connect the first air guide 3 to the housing 1.

[0121] like Figure 9 and Figure 11 As shown, the terminal end of the first air guide member 3 close to the air outlet 131 can be abutted against the second limiting plate 135 located on the first side of the air outlet 131, so as to limit the position of the first air guide member 3 through the second limiting plate 135 and prevent the first air guide member 3 from extending into the area where the air outlet 131 is located.

[0122] like Figure 8 and Figure 9As shown, the second air guide 5 may have a second mounting protrusion 51; correspondingly, a second fixing protrusion 137 may be provided on the inner wall of the housing 1. The second mounting protrusion 51 may be connected to the second fixing protrusion 137 to fix the second air guide 5 to the housing. For example, the second mounting protrusion 51 and the second fixing protrusion 137 may each be provided with a corresponding assembly hole, through which a connecting member such as a bolt may be sequentially inserted through the second mounting protrusion 51 and the second fixing protrusion 137 to securely connect the second air guide 5 to the housing 1.

[0123] like Figure 9 and Figure 14 As shown, the second air guide member 5 may have an abutment protrusion 52 at one end close to the air outlet 131, and the abutment protrusion 52 may abut against the first limiting plate 134 located on the second side of the air outlet 131 to limit the position of the second air guide member 5 through the first limiting plate 134 and prevent the second air guide member 5 from extending into the area where the air outlet 131 is located.

[0124] In some embodiments, as Figure 9 and Figure 12 As shown, the vertical top of the second air guide 5 may not exceed the vertical bottom of the air inlet 11, and the vertical direction is parallel to the opening direction K of the air outlet 131. In one example, the vertical bottom of the air inlet 11 on the side of the second air guide 5 away from the air outlet 131 is flush with the second air guide 5, and the second air guide 5 curves toward the air outlet 131 to form an arc-shaped structure that is concave toward the wind wheel 2. The vertical bottom of the air inlet 11 can be, for example, the end of the second sub-air inlet 132 described below that is closest to the air outlet 131.

[0125] The housing 1 is introduced below.

[0126] like Figure 2 、 Figure 15 and Figure 16 As shown, the housing 1 includes a fixed housing 12 and a swing housing 13; at least one of the fixed housing 12 and the swing housing 13 is provided with an air inlet 11, and an air outlet 131 is provided in the swing housing 13. The swing housing 13 is rotatably connected to the fixed housing 12, and the swing axis of the swing housing 13 is parallel to the axial direction of the wind wheel 2, so that the swing axis of the swing housing 13 intersects with the swing axis of the swing member 4.

[0127] In some embodiments, the rotation axis of the wind wheel 2 may coincide with the swing axis of the swing housing 13 .

[0128] In some embodiments, the swing angle of the swing housing 13 ranges from 30° to 60°. For example, the swing housing 13 can swing symmetrically back and forth about its swing axis, and its single-sided swing angle can be 25°, so that the swing angle of the swing housing 13 can be 50°.

[0129] The first air guide 3 and the second air guide 5 are respectively connected to the swing housing 13 so as to swing with the swing housing 13 relative to the fixed housing 12. For example, the first fixing protrusion 136 and the second limiting plate 135 for fixing the first air guide 3 are provided on the swing housing 13; the second fixing protrusion 137 and the first limiting plate 134 for fixing the second air guide 5 are provided on the swing housing 13.

[0130] In other embodiments, at least one of the first flow guide 3 and the second flow guide 5 is integral with the swing housing 13 .

[0131] In some embodiments, as Figure 15 and Figure 16 As shown, the fixed shell 12 can be sleeved on the outside of the swing shell 13, the swing shell 13 can be provided with a rotating protrusion 139, and the fixed shell 12 can be provided with a fourth rotating hole 1232. The rotating protrusion 139 can extend into the fourth rotating hole 1232 to realize the rotational connection between the fixed shell 12 and the swing shell 13.

[0132] like Figure 15 and Figure 16 As shown, the fixed housing 12 may be provided with a first sub-air inlet 121, and the swing housing 13 may be provided with a second sub-air inlet 132. The first sub-air inlet 121 and the second sub-air inlet 132 may both be located on the side of the wind rotor 2 away from the first air guide 3. Thus, when the wind rotor 2 rotates, it can draw air from the first sub-air inlet 121 and the second sub-air inlet 132, and then deliver the airflow into the air duct between the wind rotor 2 and the first air guide 3 through the rotation of the wind rotor 2. When the swing housing 13 swings relative to the fixed housing 12, the first sub-air inlet 121 and the second sub-air inlet 132 may partially overlap.

[0133] In some embodiments, as Figure 3 、 Figure 12 and Figure 17As shown, the fixed housing 12 may also be provided with a third sub-air inlet 122, which may be arranged on opposite sides of the fixed housing 12 as well as the first sub-air inlet 121. When the swing housing 13 is in its initial state with the motor not driven, the swing housing 13 does not deflect relative to the fixed housing 12. At this time, the opening directions of the first sub-air inlet 121, the second sub-air inlet 132, and the third sub-air inlet 122 are parallel to each other, for example, all parallel to the horizontal direction. In some embodiments, the opening direction of the air inlet 11 (including the first sub-air inlet 121, the second sub-air inlet 132, and the third sub-air inlet 122) may be arranged to intersect with the opening direction of the air outlet 131.

[0134] The air outlet 131 may be provided on the swing housing 13 and may be located at the bottom end of the swing housing 13 away from the fixed housing 12. When the swing housing 13 is in an initial state where the motor is not driven, the opening direction of the air outlet 131 may be parallel to the vertical direction.

[0135] In some embodiments, as Figure 15 and Figure 16 As shown, the air outlet mechanism may include a second motor 8, which is used to drive the swing housing 13 to swing. The fixed housing 12 may have a guide hole 1231. The swing housing 13 has a connecting portion 138 that passes through the arc-shaped guide hole 1231. The second motor 8 is connected to the end of the connecting portion 138 that passes through the guide hole 1231. The second motor 8 is configured to drive the connecting portion 138 to slide along the guide hole 1231, thereby causing the swing housing 13 to swing relative to the fixed housing 12.

[0136] For example, Figure 15 and Figure 16 As shown, the connecting portion 138 is offset relative to the rotating protrusion 139 .

[0137] The connecting portion 138 can be configured as a cylindrical protrusion. The second rocker arm 81 of the second motor 8 can be provided with a connecting hole 811. The end of the connecting portion 138 that passes through the guide hole 1231 can be rotatably connected to the connecting hole 811 on the second rocker arm 81. In this way, when the second motor 8 drives the second rocker arm 81 to rotate, the second rocker arm 81 can drive the connecting portion 138 to slide along the arc-shaped guide hole 1231, thereby driving the swing housing 13 to swing through the connecting portion 138.

[0138] In some embodiments, as Figure 2 、 Figure 16 and Figure 17As shown, the fixed housing 12 may include a main housing 123 and a decorative housing 124, wherein a portion of the outer wall of the main housing 123 may be recessed toward the interior of the housing 1 to form a mounting portion 1233, to which the second motor 8 may be fixed. The decorative housing 124 may be disposed on an outer side of the second motor 8 away from the main housing 123 and connected to the main housing 123, so as to conceal the second motor 8 between the main housing 123 and the decorative housing 124 and prevent it from being visible to the user. The guide hole 1231 and the fourth rotation hole 1232 may also be provided on the main housing 123 and concealed by the decorative housing 124.

[0139] In some embodiments, as Figure 2 and Figure 17 As shown, the air outlet mechanism further includes a third motor 9 for driving the wind wheel 2 to rotate axially. Figure 17 and Figure 18 As shown, the third motor 9 can be fixedly connected to the fixed housing 12, and does not swing with the swing housing 13. Figure 18 As shown, the third motor 9 and the first motor 7 can be placed on opposite sides of the wind wheel 2 in the axial direction, so as to fully utilize the space in the housing 1.

[0140] like Figure 3 、 Figure 12 and Figure 18 As shown, the first air guide 3, swinging member 4, second air guide 5, connecting member 6, and first motor 7 can each be fixed to the swing housing 13 so as to swing with the swing housing 13 relative to the fixed housing 12. In this way, even during the swinging of the swing housing 13, the first air guide 3, swinging member 4, and second air guide 5 can still function normally, and the second sub-air inlet 132 on the swing housing 13 can ensure normal air intake. The inner wall of the swing housing 13 on the side where the first motor 7 is provided can be provided with multiple partitions to separate the first motor 7 from the rotating shaft of the wind wheel 2.

[0141] An embodiment of the present application further provides a fan light having the air outlet mechanism as described above.

[0142] like Figure 19 As shown, the fan light may further include a lampshade assembly 10. This lampshade assembly 10 may be disc-shaped, for example, and disposed around the housing 1 of the air outlet mechanism. The bottom surface of the lampshade assembly 10 may be provided with a strip-shaped hole to expose the air outlet 131 in the air outlet mechanism. The light-emitting device in the fan light may be disposed on the bottom surface of the lampshade assembly 10 around the air outlet 131.
