[0027] See also Figure 1 and Figure 2A swing ceiling fan device of the present invention comprises: a mounting seat 100, wherein the mounting seat 100 is rotatably provided with a transverse bracket 200, and the transverse bracket 200 can rotate relative to the mounting seat 100 around a first horizontal axis; a fan motor 300, which is rotatably provided on the transverse bracket 200, and the fan motor 300 can rotate relative to the transverse bracket 200 around a second axis, wherein the second axis is orthogonal to the first axis, and the output shaft of the fan motor 300 is connected with a fan blade 400; a driving motor 500, which is provided on the mounting seat 100, and the output shaft of the driving motor 500 is connected with a horizontal rotating member 600, and the horizontal rotating member 600 is provided with a driving component 700 offset relative to the output shaft of the driving motor 500, and the driving component 700 has an arc surface; a transmission groove 311 which can abut against the arc surface is provided on the fan motor 300, and the arc surface can abut against the inner wall of the transmission groove 311 to drive the fan motor 300 to swing relative to the mounting seat 100.

[0028] The swing fan device of the above structure utilizes the driving motor 500 to drive the horizontal rotating member 600 to rotate. The arc surface of the driving component 700 on the horizontal rotating member 600 abuts against the transmission groove 311 on the fan motor 300 to drive the fan motor 300 to rotate around the second axis relative to the transverse bracket 200, and at the same time drives the transverse bracket 200 to rotate around the first axis relative to the mounting base 100, wherein the directions of the first axis and the second axis are orthogonal to each other, thereby realizing the swinging motion of the fan blades 400. The fan blades 400 of the swing fan device have less friction loss during the swinging motion, and the swinging is smooth and silent.

[0029] See also Figure 2 In some embodiments of the present invention, in order to facilitate the rotational connection of the fan motor 300 to the horizontal bracket 200, a mounting plate 320 is provided on the fan motor 300, and the mounting plate 320 is rotatably set on the horizontal bracket 200. The mounting plate 320 can rotate relative to the horizontal bracket 200 around the second axis. The mounting plate 320 is provided with a transmission bracket 310 that can be tilted relative to the horizontal rotating member 600, and a transmission groove 311 is provided on the transmission bracket 310.

[0030] See also Figure 2 and Figure 3 In some embodiments of the present invention, in order to adjust the range of the swinging motion of the fan blade 400, and thus expand or reduce the blowing range of the swing fan device, the horizontal rotating member 600 is provided with an adjusting mechanism 800, and the adjusting mechanism 800 is used to adjust the distance between the driving component 700 and the output shaft of the driving motor 500 to adjust the inclination angle of the mounting plate 320 relative to the horizontal rotating member 600. Figure 3When the distance between the driving component 700 and the output shaft of the driving motor 500 is reduced, the inclination angle of the mounting plate 320 relative to the horizontal rotating member 600 increases; conversely, when the distance between the driving component 700 and the output shaft of the driving motor 500 is increased, the inclination angle of the mounting plate 320 relative to the horizontal rotating member 600 decreases. It should be noted that the adjustment mechanism 800 adjusts the inclination angle of the fan motor 300 relative to the vertical direction to be 0 to 45 degrees.

[0031] See also Figure 3 In some embodiments of the present invention, the adjustment mechanism 800 includes a long groove 810 provided on the horizontal rotating member 600 and extending in the horizontal direction, the side wall of the horizontal rotating member 600 is provided with a long through hole 820 connected to the long groove 810, and the extension direction of the long through hole 820 is consistent with the long groove 810. The output shaft of the drive motor 500 or the drive component 700 is slidably provided in the long groove 810, and the horizontal rotating member 600 is provided with a fastener 830 passing through the long through hole 820. The fastener 830 fixes the output shaft of the drive motor 500 or the drive component 700 to the horizontal rotating member 600, and the transmission groove 311 includes at least two positioning grooves 3111 corresponding to the drive component 700, or the transmission groove 311 is a strip groove corresponding to the drive component 700.

[0032] See also Figure 2 and Figure 3 The fastener 830 is used to fix the output shaft of the driving motor 500 on the horizontal rotating member 600. When the distance between the driving component 700 and the output shaft of the driving motor 500 needs to be adjusted, the fastener 830 is first loosened so that the output shaft of the motor can be close to or away from the driving component 700 along the extension direction of the long groove 810. When the position is adjusted to the right position, the fastener 830 is used to lock the output shaft of the driving motor 500 on the horizontal rotating member 600, so that the position of the driving component 700 relative to the transmission bracket 310 is adjusted. When the transmission groove 311 includes at least two positioning grooves 3111, when the distance between the driving component 700 and the output shaft of the motor changes, the driving component 700 can enter the other positioning groove 3111 from one positioning groove 3111. When the transmission groove 311 is a strip groove, when the distance between the driving component 700 and the output shaft of the motor changes, the arc surface of the driving component 700 can abut against another position of the strip groove.

[0033] It should be noted that the transmission groove 311 and the positioning groove 3111 can be either a through hole groove or a sink groove. The shape and size of the transmission groove 311 can be matched and set according to actual use needs.

[0034] See also Figure 3In some embodiments of the present invention, in order to improve the transmission stability and transmission accuracy, the driving component 700 includes a driving shaft 710 and a sphere 720 connected to the lower end of the driving shaft 710, the arc surface is the spherical surface of the sphere 720, and the shape of the transmission groove 311 matches the sphere 720 to prevent the transmission groove 311 from moving along the radial direction of the sphere 720. It can be understood that in other embodiments, the sphere 720 can also be replaced by a cone, and the surface of the cone is matched with the transmission groove 311.

[0035] See also Figure 1 In some embodiments of the present invention, a protective cover 110 is detachably mounted on the mounting seat 100 and covers the outside of the transverse bracket 200, the fan motor 300 and the drive motor 500. An opening is provided at the lower end of the protective cover 110, and a flexible dust cover 120 is provided at the opening to allow the output shaft of the fan motor 300 to pass through and seal the opening. The protective cover 110 is detachably mounted on the mounting seat 100 to help adjust the swing angle of the fan motor 300. In addition, it should be noted that during the swinging motion of the fan blade 400, the protective cover 110 is relatively fixed to the mounting seat 100 to prevent the protective cover 110 from rotating with the fan motor 300 and easily interfering with external objects. In this embodiment, the flexible dust cover 120 is made of leather material for easy cleaning. Of course, in other embodiments, the flexible dust cover 120 can also be made of cloth.

[0036] See also Figure 4 In some embodiments of the present invention, in order to further facilitate the installation and removal of the protective cover 110, the upper part of the protective cover 110 is provided with a connecting column 111 extending upward, and the upper end of the connecting column 111 is provided with an anti-slip head 112. The mounting seat 100 is provided with an arc-shaped mounting hole 101, and the end of the arc-shaped mounting hole 101 is provided with an expansion portion 102 for the anti-slip head 112 to pass through. During installation, the anti-slip head 112 is passed through the expansion portion 102, and then the protective cover 110 is driven to rotate horizontally at a certain angle, so that the connecting column 111 enters the arc-shaped mounting hole 101, and the anti-slip head 112 cannot be separated from the arc-shaped mounting hole 101 in the vertical direction. During removal, the protective cover 110 is driven to rotate horizontally at a certain angle, so that the anti-slip head 112 is aligned with the expansion portion 102, and the anti-slip head 112 can be separated from the arc-shaped mounting hole 101 in the vertical direction, thereby realizing the removal of the protective cover 110.

[0037] See also Figure 1 In some embodiments of the present invention, in order to enrich the functions of the swing fan device, a light emitting assembly 900 is provided on the mounting base 100, thereby combining the functions of a fan and a lamp.

[0038] See also Figure 1In some embodiments of the present invention, the light-emitting component 900 is an annular light-emitting body located on the periphery of the transverse bracket 200, the fan motor 300, the drive motor 500 and the fan blades 400. The annular light-emitting body is connected to the mounting base 100 by at least two connecting rods 910. An accommodating space is defined between the mounting base 100, the connecting rods 910 and the annular light-emitting body. The light-emitting component 900 is cleverly configured as an annular light-emitting body surrounding the fan motor 300 and the fan blades 400, which not only realizes the function of a fan light, but also has a very compact structure.

[0039] In some embodiments of the present invention, the drive motor 500 is electrically connected to the controller, and the controller can control the drive motor 500 to rotate clockwise to a first preset angle and control the drive motor 500 to rotate counterclockwise to a first preset angle. Specifically, for example, the controller controls the drive motor 500 to rotate clockwise so that the fan blades 400 swing clockwise about 40° around a vertical axis, and then the controller controls the drive motor 500 to rotate counterclockwise so that the fan blades 400 swing counterclockwise about 40° around a vertical axis, thereby completing the reset. This structural form can enable the swing fan device to swing back and forth within a certain angle range, thereby sweeping air over a certain area. Of course, it is understandable that the drive motor 500 can also maintain clockwise or counterclockwise rotation so that the swing fan device can rotate.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
