For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0036] An embodiment of this application provides a ceiling fan.

[0037] Reference Figures 1 to 7 A ceiling fan, comprising: a support rod 100, an electric motor 200, a light source 300, a housing 400, and fan blades 500.

[0038] The electric actuator 200 is mounted on the support rod 100; the light-emitting element 300 is mounted on the support rod 100; the housing 400 covers the electric actuator 200 and the light-emitting element 300; the fan blade 500 is driven to rotate by the electric actuator 200, and the fan blade 500 is provided with a light inlet 530 facing the light-emitting element 300; the light emitted by the light-emitting element 300 enters the interior of the fan blade 500 through the light inlet 530, is reflected and conducted inside the fan blade 500, and is emitted through the blade surface 520 of the fan blade 500.

[0039] In this embodiment, the ceiling fan is supported and suspended by the support rod 100; the fan blades 500 are driven to rotate by the electric device 200 to blow air; the light source 300 emits light to provide illumination. At the same time, the light emitted by the light source 300 enters the interior of the fan blades 500 through the light inlet 530, is reflected and conducted inside the fan blades 500, and is emitted through the blade surface 520 of the fan blades 500. The light is diffused by the reflection effect, and the light emitted from the blade surface 520 of the fan blades 500 can illuminate a larger area and is softer.

[0040] In some embodiments, the upper end of the support rod 100 is provided with a suspension member. The ceiling fan is suspended from the ceiling by the suspension member. The suspension member is provided with screw holes and screws, and is fixed to the ceiling by screw connection.

[0041] Reference Figure 6 The support rod 100 is a hollow rod, and the support rod 100 is provided with an electrical cable channel through which the power supply line passes.

[0042] Reference Figure 3In some embodiments, the fan blade 500 includes an upper fan blade member 510, which is combined with the blade surface 520 to form a light channel 540. The light inlet 530 is connected to the light channel 540. The light emitted by the light-emitting element 300 enters the interior of the fan blade 500 through the light inlet 530 and is reflected and conducted along the light channel 540 inside the fan blade 500.

[0043] It is understandable that the upper fan blade 510 and the blade surface 520 can be two parts, which are fitted together by means of snaps or screws to form the fan blade 500. Alternatively, the upper fan blade 510 and the blade surface 520 can be integrally formed to create a fan blade 500 with an internal light channel 540.

[0044] Reference Figures 2 to 5 In some embodiments, the inner surface of the light channel 540 is provided with multiple reflective surfaces 511. These reflective surfaces 511 reflect and transmit the light emitted by the light-emitting element 300 from the light inlet 530 to the end of the fan blade 500 away from the light inlet 530. The reflective surfaces 511 can be formed by texturing or etching. The reflective surfaces 511 are made of a material with high reflectivity, such as an aluminum film. Multiple reflective surfaces 511 are provided on the upper and lower surfaces of the light channel 540. Some reflective surfaces 511 direct light towards other reflective surfaces 511, and the light is propagated from one end of the fan blade 500 to the other through the reflection of the reflective surfaces 511, ensuring light propagation throughout the entire fan blade 500.

[0045] In some embodiments, the texture marks are lines radiating outwards from the edge of a semicircle, with the lines intersecting to form polygons, most of which are rhomboid quadrilaterals.

[0046] Because frosted surfaces have lower light transmittance than flat surfaces, in some embodiments, the upper and lower surfaces of the fan blades can be glossy, while the outer edge between the upper and lower surfaces can be frosted to reduce light transmission at the edges of the fan blades, thereby providing a softer visual effect. Furthermore, decorative frosted textured lines can be provided on the upper surface of the fan blades to provide an aesthetically pleasing interplay of light and shadow.

[0047] In some embodiments, the fan blade 500 has an overall aerodynamically irregular curved surface, which improves the airflow effect when the fan blade 500 rotates. Similarly, the light channel 540 has an irregular curved surface with a shape basically the same as that of the fan blade 500. The irregular curved surface is not a flat plane, which facilitates the reflection and transmission of light within the light channel 540.

[0048] In some embodiments, at least some internal structures of the fan blades 500 are made of a light-transmitting material, such that light reflected within the light channel 540 can pass through the blade surface 520 made of the light-transmitting material. The light-transmitting material can be a material with high light transmittance, such as PVC.

[0049] During the reflection and transmission of light along the light channel 540, one part of the reflective surface 511 directs the light to another reflective surface 511, while the other part of the reflective surface 511 directs the light to the leaf surface 520 made of light-transmitting material.

[0050] The position, angle, and area of ​​the reflective surface 511, as well as the position of the leaf surface 520 made of light-transmitting material, are set by designing a light transmission path.

[0051] Reference Figure 6 and Figure 7 In some embodiments, the support rod 100 is connected to a first mounting member 310, which is disc-shaped, and the support rod 100 passes through the first mounting member 310. A plurality of light-emitting elements 300 are disposed on the outer surface of the first mounting member 310, and the plurality of light-emitting elements 300 are arranged along the circumference of the first mounting member 310 and around the support rod 100, so that the plurality of light-emitting elements 300 can emit light in all directions.

[0052] Understandably, the first mounting component 310 is fixedly mounted on the support rod 100 and located at the lower end of the support rod 100, and the light-emitting component 300 is fixedly mounted on the first mounting component 310. When the electric device 200 drives the fan blade 500 to rotate, the support rod 100 will not rotate, so the first mounting component 310 will not rotate, and the light-emitting component 300 on the first mounting component 310 will also not rotate.

[0053] The wires of the wire channel of the support rod 100 extend from the lower end of the support rod 100 into the first mounting member 310 and are connected to the light-emitting element 300 on the first mounting member 310, so as to transmit electrical energy to the light-emitting element 300 to make the light-emitting element 300 energized and emit light.

[0054] Reference Figure 7 The light-emitting element 300 can be an LED lamp element packaged as a surface mount or a lamp bead. Preferably, the first mounting member 310 is disc-shaped, and multiple surface mount packaged light-emitting elements 300 are soldered to a flexible circuit strip at a given (e.g., the same) spacing, then bent into a ring shape, and then fitted onto the circumference of the first mounting member 310. Thus, this structural configuration achieves the fixation of multiple light-emitting elements 300 to the first mounting member 310, and also provides a compact electrical connection.

[0055] Reference Figure 6There are multiple fan blades 500, which are spliced ​​together so that the light inlets 530 of the multiple fan blades 500 surround the first mounting member 310. The spliced ​​multiple fan blades 500 form a circle at the center, with the light inlets 530 located on the sides of the fan blades 500. The light inlets 530 of the multiple fan blades 500 also form a circle, and the first mounting member 310 is located in the center of the circle. Multiple light-emitting elements 300 are arranged circumferentially along the first mounting member 310 and are located on the same horizontal plane. The light inlets 530 of the spliced ​​multiple fan blades 500 are located on the same horizontal plane, and the light-emitting elements 300 and the light inlets 530 are located on the same horizontal plane. The light-emitting direction of the light-emitting elements 300 is towards the light inlets 530. When the electric device 200 drives the fan blade 500 to rotate, the light-emitting element 300 on the first mounting part 310 does not rotate. Multiple light-emitting elements 300 emit light in all directions, and the multiple light inlets 530 arranged in a circle remain circular when the fan blade 500 rotates. Therefore, during the rotation of the fan blade 500, the light emitted by the light-emitting elements 300 can still enter the light channel 540 of the fan blade 500 through the light inlets 530.

[0056] Multiple light-emitting elements 300 are arranged circumferentially along the first mounting member 310 and emit light in all directions; light from different directions enters the light channel 540 of the fan blade 500 from different positions of the light inlet 530.

[0057] Reference Figure 1 In some embodiments, there are two fan blades 500, and the two fan blades 500 are identical in shape. The light inlet 530 of the fan blade 500 is semi-circular, and the light inlets 530 of the two fan blades 500 form a circle. The inner edges on both sides of the light inlet 530 are straight, and the inner edges of the two fan blades 500 can be joined together accordingly.

[0058] The distance between the light-emitting element 300 and the light inlet 530 should be set close enough so that the light emitted by the light-emitting element 300 enters the light channel 540 through the light inlet 530 as much as possible. For example, in some embodiments, the distance between the light-emitting element 300 and the light inlet 530 is set to within 10 mm. Of course, in other embodiments, the distance between the light-emitting element 300 and the light inlet 530 can be set to other values ​​according to actual production needs.

[0059] Reference Figure 6 In some embodiments, the electric actuator 200 includes a rotor 220 and a stator 210, the stator 210 being connected to the support rod 100, the rotor 220 being connected to the housing 400, and the housing 400 being connected to the fan blades 500. Preferably, the electric actuator 200 is implemented as a motor assembly.

[0060] The stator 210 surrounds the outside of the support rod 100. The rotor 220 is disposed outside the stator 210, and the housing 400 is disposed outside the rotor 220.

[0061] When the electric actuator 200 is energized, the stator 210's coil windings generate a rotating magnetic field, which acts on the rotor 220 to create a magnetoelectric torque, causing the rotor 220 to rotate. The rotor 220 drives the housing 400 and the fan blades 500 connected to the housing 400 to rotate. The fan blades 500 rotate to blow air.

[0062] The support rod 100 has a hole at the position corresponding to the electric device 200 that connects to the wire channel; the wires of the wire channel pass through the hole and connect to the electric device 200, transmitting electrical energy to the electric device 200 to drive the electric device 200 to operate.

[0063] Reference Figure 6 In some embodiments, the housing 400 includes a first sub-housing 410, the rotor 220 is connected to the first sub-housing 410, and a first bearing is provided between the first sub-housing 410 and the support rod 100.

[0064] The first sub-shell 410 is lid-shaped. A support rod 100 passes through the center of the upper cover surface of the first sub-shell 410. A hollow protruding cover is provided at the center of the upper cover surface of the first sub-shell 410, and a first bearing is disposed within the hollow protruding cover. The first bearing allows the first sub-shell 410 to rotate smoothly around the support rod 100 under the drive of the electric device 200. A rotor 220 is disposed on the inner sidewall of the first sub-shell 410.

[0065] In some embodiments, the housing 400 includes a second sub-housing 420, which is connected to the upper surface of the fan blade 500, and the second sub-housing 420 is connected to the first sub-housing 410 via a connecting piece 430.

[0066] The second sub-shell 420 includes a first annulus 421, a second annulus 422, and a cylindrical sidewall 423. The outer edge of the first annulus 421 is connected to the upper edge of the cylindrical sidewall 423, and the inner edge of the second annulus 422 is connected to the lower edge of the cylindrical sidewall 423. The first annulus 421 is provided with a screw hole, and the first annulus 421 abuts against the connecting piece 430; the second sub-shell 420 and the connecting piece 430 are connected by a screw passing through the screw hole. The second annulus 422 is provided with a screw hole, and the second annulus 422 abuts against the upper surface of the fan blade 500; the second sub-shell 420 and the fan blade 500 are connected by a screw passing through the screw hole. The second sub-shell 420 is connected to the upper surface of the fan blade 500, allowing the fan blade 500 to pass through the shell 400 and enter the interior of the shell 400. The light-emitting element 300 is disposed inside the shell 400, which allows the light inlet 530 of the fan blade 500 to be close to the light-emitting element 300, so that the light emitted by the light-emitting element 300 can enter the light channel 540 from the light inlet 530 as much as possible, and so that more light is emitted from the fan blade 500.

[0067] Reference Figure 6 In some embodiments, a second bearing 620 is provided between the connecting piece 430 and the support rod 100. The connecting piece 430 is circular, and the support rod 100 passes through the center of the connecting piece 430. The second bearing 620 enables the connecting piece 430 and the second sub-housing 420 connected to the connecting piece 430 to rotate smoothly around the support rod 100.

[0068] The connecting piece 430 is provided with three layers of ladders, each layer being annular and of different heights, gradually increasing in height from the inside out. A sleeve 434 extends downwards from the inner edge of the first ladder 431, and a second bearing 620 is positioned between the sleeve 434 and the support rod 100. The rotor 220 is supported on the second ladder 432, which, together with the first sub-housing 410, forms a space to accommodate the rotor 220. The third ladder 433 abuts against the second annular ring 422, and the third ladder 433 is connected to the second annular ring 422 by screws.

[0069] The first sub-shell 410, the connecting piece 430, and the second sub-shell 420 are connected by screws. Of course, in other embodiments, they can also be connected in other ways, such as welding.
