[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0062] This application provides an air supply device, such as... Figure 1 , Figure 2 and Figure 3As shown, the air supply device includes a base 100, a swing housing 200, a wind turbine 300, a volute 400, a volute tongue 500, and at least one oscillating blade 600. The base 100 has an air inlet 110. The wind turbine 300 and the swing housing 200 are rotatably connected to the base 100, and the swing axis of the swing housing 200 is parallel to the rotation axis of the wind turbine 300. The swing housing 200 has an air outlet 210. The volute 400 and the volute tongue 500 are located on opposite sides of the air outlet 210 and are fixedly connected to the swing housing 200. At least one oscillating blade 600 is located between the volute 400 and the volute tongue 500 and is rotatably connected to both. The swing axis of the oscillating blade 600 intersects the rotation axis of the wind turbine 300.

[0063] It is understandable that, since the swing axis of the swing housing 200 is parallel to the rotation axis of the wind turbine 300, while the swing axis of the blade 600 intersects with the rotation axis of the wind turbine 300, the swing axis of the blade 600 intersects with the swing axis of the swing housing 200.

[0064] The air supply device provided in this application embodiment has a swing housing 200 with an air outlet 210 that can swing relative to the base 100. The swing of the swing housing 200 can adjust the orientation of the air outlet 210 and expand the air outlet range of the air outlet 210. The oscillating blade 600 is disposed between the volute 400 and the volute tongue 500, which are located on opposite sides of the air outlet 210. Therefore, the oscillating blade 600 can be oriented toward the air outlet 210, and the oscillating blade 600 can swing relative to the swing housing 200. The swing axis of the oscillating blade 600 intersects with the swing axis of the swing housing 200, so the oscillating blade 600 can expand the air outlet range of the air outlet 210 from a direction different from the swing housing 200. Therefore, the air supply device provided in this application embodiment expands the air outlet range of the air outlet 210 from different directions by cooperating with the swing housing 200 and the swing blade 600 whose swing axes intersect, thereby improving the air supply effect of the air supply device.

[0065] In some embodiments, the air outlet 210 can be configured as a rectangular opening, and the length direction of the air outlet 210 can be parallel to the swing axis of the swing housing 200. The swing axis of the oscillating blade 600 is perpendicular to the swing axis of the swing housing 200. The rotation axis of the impeller 300 and the swing axis of the swing housing 200 can be parallel to the axial direction of the impeller 300. In this case, the oscillating blade 600 can expand the air outlet range of the air supply device in the length direction (or the axial direction of the impeller 300) of the air outlet 210; the swing housing 200 can expand the air outlet range of the air supply device in the width direction of the air outlet 210.

[0066] In some embodiments, such as Figure 2 As shown, the air supply device includes a plurality of oscillating blades 600, which are spaced apart along the rotation axis of the impeller 300. Exemplarily, the plurality of oscillating blades 600 can be arranged at equal intervals and are parallel to each other, so that the orientation of each of the plurality of oscillating blades 600 (or the angle between them and the swing axis of the swing housing 200) is the same.

[0067] like Figure 2 and Figure 4 As shown, the air supply device also includes a linkage 700 and a first drive 800. The linkage 700 is connected to the first drive 800 and multiple oscillating blades 600 respectively. The first drive 800 is mounted on and connected to the swing housing 200, and is configured to drive the oscillating blades 600 to oscillate via the linkage 700. Thus, multiple oscillating blades 600 can be connected simultaneously through one linkage 700 to achieve synchronous drive among them, avoiding interference caused by different oscillation directions. Furthermore, by driving all oscillating blades 600 to rotate synchronously through one first drive 800, the driving cost of the oscillating blades 600 is reduced, and the space occupied inside the swing housing 200 is also reduced.

[0068] like Figure 2 and Figure 4 As shown, the linkage 700 can be configured as a plate-like structure, and the plate-like structure is parallel to the swing axis of the swing housing 200 and perpendicular to the swing axis of the swing blade 600.

[0069] In some embodiments, such as Figure 5 and Figure 6 As shown, the first driving member 800 includes a first driving motor 810 and a crank 820. The first driving motor 810 is fixedly connected to the swing housing 200, and the crank 820 is connected to the first output shaft 811 of the first driving motor 810. The rotation axis of the first output shaft 811 is parallel to the swing axis of the oscillating blade member 600. The crank 820 has a rotating shaft 821 and a connecting portion 822 arranged at intervals on the side away from the first output shaft 811. The rotating shaft 821 is rotatably connected to the swing housing 200, and the rotating shaft 821 and the first output shaft 811 are arranged on the same rotation axis. The connecting portion 822 is connected to the linkage member 700.

[0070] In addition, the first driving component 800 also includes a fixing base 830, through which the first driving motor 810 is fixedly connected to the swing housing 200. In one example, the inner side of the swing housing 200 may be provided with a boss with a hole, and the fixing base 830 may be provided with a through hole. Bolts and other connecting parts can pass through the through hole and the hole on the boss in sequence to fix the fixing base 830 to the swing housing 200. The height of the boss can be adjusted according to the position of the first output shaft 811 and the position of the linkage 700.

[0071] like Figure 6 As shown, a sleeve 823 can be provided on the side of the crank 820 near the first drive motor 810. The first output shaft 811 of the first drive motor 810 can extend into the sleeve 823, so that when the first output shaft 811 rotates, it can drive the crank 820 with the sleeve 823 to rotate. The centerline of the sleeve 823 coincides with the centerline of the rotating shaft 821. Therefore, the rotating shaft 821 can provide an additional rotational connection point for the crank 820, making the rotation of the crank 820 more stable, and thus making the movement of the crank 820 driving the linkage 700 more stable.

[0072] like Figure 6 As shown, to conveniently limit the swing range of the swing housing 200, a limiting wall 220 can be provided on the inner side of the swing housing 200. The limiting wall 220 has a rotation hole 221 and a pair of limiting protrusions 222, which are arranged opposite to each other along the rotation axis of the impeller 300. The rotation shaft 821 of the crank 820 cooperates with the rotation hole 221, and the crank 820 is located between the pair of limiting protrusions 222. The limiting protrusions 222 are configured to limit the swing range of the crank 820.

[0073] In some embodiments, a pair of limiting protrusions 222 may be arranged perpendicular to the limiting wall 220. The connecting portion 822 on the crank 820 is located above the rotating shaft 821. The extension length of the connecting portion 822 may be greater than the extension length of the rotating shaft 821, and the linkage 700 is rotatably connected to the end of the connecting portion 822 away from the first drive motor 810. Thus, the linkage 700 and the limiting wall 220 can have a large clearance space in the extension direction of the connecting portion 822 (perpendicular to the linkage 700). The rotating hole 221 on the limiting wall 220 that mates with the rotating shaft 821 is located between the pair of limiting protrusions 222.

[0074] In some embodiments, such as Figure 4 , Figure 7 and Figure 8As shown, each oscillating blade 600 includes a first shaft 610, a second shaft 620, and a drive unit 630. The first shaft 610 is rotatably connected to the volute 400, and the second shaft 620 is rotatably connected to the volute tongue 500. The first shaft 610 and the second shaft 620 share a common axis of rotation. That is, the central axes of the first shaft 610 and the second shaft 620 coincide, and the central axes of the first shaft 610 and the second shaft 620 serve as the oscillation axis of the oscillating blade 600.

[0075] Either the volute 400 or the volute tongue 500 has a first track hole 510. The drive unit 630 passes through the first track hole 510 and is connected to the linkage 700. The first drive unit 800 is configured to drive the oscillating blade 600 to oscillate along the first track hole 510 via the linkage 700. The first track hole 510 is configured to limit the oscillation trajectory of the oscillating blade 600.

[0076] In some embodiments, such as Figure 8 As shown, the first track hole 510 can be provided on the volute tongue 500, and the first track hole 510 can be an arc-shaped hole recessed in the direction away from the air outlet 210 of the volute tongue 500.

[0077] In addition, the volute 400 is provided with a first mating hole 410 that mates with the first shaft 610; the volute tongue 500 may be provided with a second mating hole 520 that mates with the second shaft 620, and the second mating hole 520 is located on the recessed side of the first track hole 510, so that the second mating hole 520 is located on the side of the first track hole 510 facing the air outlet 210, so that the oscillating blade 600 swings in the direction toward the air outlet 210.

[0078] In some embodiments, such as Figure 3 As shown, the drive unit 630 can be located on the side of the second shaft 620 away from the air outlet 210. The drive unit 630 includes a third shaft, and the linkage 700 has a rotating hole. The rotational connection between the drive unit 630 and the linkage 700 is achieved through the cooperation of the third shaft and the rotating hole. Similarly, the connecting part 822 can include a fourth shaft, through which it is rotatably connected to the linkage 700. In this way, the degree of freedom between the linkage 700 and the drive unit 630 or the connecting part 822 can be increased, making the oscillation of the oscillating blade 600 smoother.

[0079] The first output shaft 811 of the first drive motor 810 can be perpendicularly connected to the crank 820, and the rotation axis of the first output shaft 811 and the rotation axis of the oscillating blade 600 are located on the same plane and are parallel to each other; the linkage 700 is connected to the end of the crank 820 away from the first drive motor 810, and the rotation axis of the linkage 822 and the axis of the drive part 630 among the plurality of oscillating blades 600 are located on the same plane and are parallel to each other.

[0080] In some embodiments, the base 100 may be rectangular to form a receiving cavity, and one side of the base 100 may be open. The swing housing 200 is partially received within the receiving cavity through the opening on the open side, so that the base 100 can cover the outside of the swing housing 200. Thus, the air inlet 110 on the base 100 can communicate with the air outlet 210 on the swing housing 200 through the receiving cavity.

[0081] In some embodiments, such as Figure 9 As shown, the swing axis of the swing housing 200 coincides with the rotation axis of the impeller 300. Thus, with a fixed size of the base 100 and the opening size of the open side of the base 100, the swing housing 200 is allowed to achieve a larger swing range.

[0082] like Figure 2 and Figure 3 As shown, the side of the swing housing 200 away from the base 100 can be configured as an arc-shaped curved structure to avoid interference with the side wall of the base 100 when the swing housing 200 swings relative to the base 100. In other words, the outer surface of the side of the swing housing 200 away from the base 100 is configured as a curved surface.

[0083] In some embodiments, such as Figure 3 As shown, on a cross-section perpendicular to the swing axis of the swing housing 200, the distances between the two ends of the swing housing 200 along the circumference of the impeller 300 and the swing axis of the swing housing 200 are equal. That is, the surface can be symmetrical about a set plane, which is parallel to the opening direction of the air outlet 210 and passes through the swing axis of the swing housing 200. In this way, the swing housing 200 can swing symmetrically on both sides of its swing axis, so that the swing trajectory of the swing housing 200 is a reciprocating motion centered on its swing axis, simplifying the driving of the swing housing 200 by the first drive member 800.

[0084] like Figure 3 As shown, the air outlet 210 can be opened at this curved surface. Furthermore, the air outlet 210 can be symmetrical about a set plane, which is parallel to the opening direction of the air outlet 210 and passes through the swing axis of the swing housing 200.

[0085] For example, the air outlet 210 may be located in the central region of the curved surface, and the center of the air outlet 210 coincides with the center of the curved surface. In other embodiments, the air outlet 210 may also be located offset relative to the center of the curved surface.

[0086] In some embodiments, such as Figure 2 and Figure 10As shown, the swing housing 200 includes a swing protrusion 230, and the base 100 has a second track hole 120, with the swing protrusion 230 partially located within the second track hole 120. The air supply device also includes a second drive member 900, which is mounted on the base 100 and connected to the swing protrusion 230. The second drive member 900 is configured to drive the swing housing 200 to swing along the second track hole 120. Similar to the first track hole 510 described above, the second track hole 120 can be used to limit the swing trajectory of the swing housing 200. The second track hole 120 can be an arc-shaped hole to accommodate the swing of the swing housing 200.

[0087] like Figure 1 and Figure 10 As shown, a recess 160 can be formed on one end wall of the base 100. A stepped structure 161 can be formed within the recess 160. The bottom wall of the stepped structure 161 facing the swing housing 200 can serve as a mounting portion for the second drive member 900, providing mounting support for the second drive member 900. The second drive member 900 can be fixed to the stepped structure 161 by bolts or other connecting members. For example, the recess 160 can be a rectangular recess.

[0088] In one example, the swing housing 200 may further include a rotatable protrusion 240, which engages with a rotatable hole on the base 100 to achieve a rotatable connection. Figure 1 and Figure 10 As shown, the swing protrusion 230 can be radially offset relative to the rotating protrusion 240 along the impeller 300. For example, the air outlet 210 is located on the side of the swing housing 200 away from the base 100, and the swing protrusion 230 can be closer to the air outlet 210 relative to the rotating protrusion 240, with the direction from the swing protrusion 230 to the rotating protrusion 240 intersecting the opening direction of the air outlet 210. This arrangement facilitates the second drive member 900 in driving the swing housing 200 to swing.

[0089] In some embodiments, such as Figure 10 As shown, the second drive unit 900 includes a second drive motor 910, a second crank 920, and a connecting rod 930; the second drive motor 910 is fixedly connected to the base 100, one end of the second crank 920 is fixedly connected to the second output shaft 911 of the second drive motor 910, and the other end is rotatably connected to the connecting rod 930; the end of the connecting rod 930 away from the second crank 920 is rotatably connected to the swing protrusion 230.

[0090] like Figure 2 and Figure 10 As can be seen, the swing protrusion 230 can be configured as a columnar protrusion, thereby including a shaft portion for rotatable connection with the mounting hole (not shown in the figure) opened on the connecting rod 930.

[0091] In some embodiments, the end of the second crank 920 connected to the second output shaft 911 may have a circular or polygonal hole (e.g., a strip hole), and the second output shaft 911 may be fixed in the hole to prevent relative sliding between the second crank 920 and the second output shaft 911, which would reduce transmission efficiency. Similar to the swing protrusion 230 described above, the end of the second crank 920 connected to the connecting rod 930 may be provided with a shaft to facilitate rotatable connection with a mounting hole (not shown in the figure) on the connecting rod 930.

[0092] In some embodiments, such as Figure 9 and Figure 11 As shown, the air supply device also includes a third drive component 1000, which is mounted on the base 100 and connected to the impeller 300. The third drive component 1000 is configured to drive the impeller 300 to rotate. The third drive component 1000 is located on the first side of the impeller 300, and the first drive component 800 and the second drive component 900 are located on the second side of the impeller 300. The first drive component 800 is used to drive the oscillating blade 600 to oscillate, and the second drive component 900 is used to drive the oscillating housing 200 to oscillate. The first side and the second side are opposite to each other.

[0093] In one example, the power of the third drive element 1000 may be greater than that of the first drive element 800 and the second drive element 900. Therefore, by arranging the third drive element 1000 separately on one side of the impeller 300, interference between the third drive element 1000 and the first drive element 800 and the second drive element 900 can be avoided, and the receiving space formed by the base 100 and the swing housing 200 can be fully utilized. Exemplarily, the third drive element 1000 can be a drive motor.

[0094] like Figure 11 and Figure 12 As shown, the base 100 has a first bracket 130 and a second bracket 140, which are arranged opposite to each other along the axial direction of the impeller 300. The second bracket 140 has a bearing hole 141. The impeller 300 has a mating hole 310 on the side near the first bracket 130. The first bracket 130 is fixedly connected to a third drive member 1000, and the third output shaft 1010 of the third drive member 1000 extends into the mating hole 310. The impeller 300 has a fixed shaft 320 on the side near the second bracket 140, and a bearing 330 is rotatably mounted on the fixed shaft 320, located within the bearing hole 141.

[0095] In one example, the bearing 330 may be fixed within the bearing bore 141 and rotatably mounted on the fixed shaft 320. Alternatively, the bearing 330 may be fixedly mounted on the fixed shaft 320 and may rotate within the bearing bore 141.

[0096] In some embodiments, such as Figure 13 As shown, the air supply device may also include a lighting component 1100, thereby enriching the functionality of the air supply device. For example, the air supply device is a fan light.
