Description

Technical Field

[0001] This invention relates to the field of fan light technology, and more particularly to a fan blade structure and a fan light. Background Technology

[0002] As people's living standards continue to improve, the variety of lighting fixtures is also increasing. Among them, fan lights are becoming more and more widely used because they have the dual functions of lighting and fan operation.

[0003] To improve airflow and enhance the blowing effect, commercially available fan lights typically feature modified fan blades. However, after these modified blades are connected to the fan light body, the overall strength of the blades and the connection strength must be considered. This is because, during fan light rotation, the blades are highly susceptible to deformation or bending due to air impact, thus affecting the lifespan of both the blades and the fan light.

[0004] In view of this, it is indeed necessary to provide an improved fan blade structure and fan light to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a fan blade structure and a fan light to improve the overall strength of the fan blade structure.

[0006] To achieve the above objectives, the present invention provides a fan blade structure, including a fan blade body. The fan blade body includes a first side located on the windward side, a second side located on the leeward side, and a third side connecting the first side and the second side. The first side, the second side, and the third side are all curved sides. The end of the fan blade body closer to the third side is defined as the fan blade tip, and the end of the fan blade body away from the third side is defined as the fan blade root. The fan blade structure further includes a first reinforcing rib and a second reinforcing rib. The first reinforcing rib is disposed along the length direction of the fan blade body and extends from the fan blade root toward the fan blade tip; the second reinforcing rib is disposed at the fan blade root.

[0007] As a further improvement of the present invention, the fan blade structure further includes a flow guide portion, wherein the first side, the second side and the third side surround and form the outer peripheral edge of the flow guide portion, and the first reinforcing rib is disposed on the middle region in the width direction of the flow guide portion, and the width of the first reinforcing rib gradually decreases.

[0008] As a further improvement of the present invention, the fan blade structure further includes a connecting structure, which is fixedly connected to the side of the fan blade root away from the fan blade end and is disposed between the first side and the second side, and the two ends of the second reinforcing rib are respectively connected to the connecting structure and the fan blade root.

[0009] As a further improvement of the present invention, a plurality of second reinforcing ribs are provided and arranged in a ring at equal intervals between the connecting structure and the root of the fan blade.

[0010] As a further improvement of the present invention, the highest point of the fan blade structure is located at the end of the first side near the end of the fan blade; the lowest point of the fan blade structure is located at the end of the second side near the root of the fan blade.

[0011] As a further improvement of the present invention, the horizontal plane where the lowest point of the fan blade structure is located is flush with the horizontal plane where the root of the fan blade is located.

[0012] As a further improvement of the present invention, the thickness of the fan blade body gradually decreases from the root of the fan blade to the tip of the fan blade.

[0013] To achieve the above objectives, the present invention also provides a fan light, including a fan light body and a plurality of the aforementioned fan blade structures, wherein the plurality of fan blade structures are folded or unfolded on the fan light body.

[0014] As a further improvement of the present invention, the fan light includes three fan blade structures, and the orthographic projections of adjacent fan blade structures on the horizontal plane do not overlap.

[0015] As a further improvement of the present invention, when all three fan blade structures are retracted into the fan light, the side of the second side of the first fan blade structure near the end of the fan blade is arranged opposite to the side of the first side of the second fan blade structure near the root of the fan blade, and a gap is formed between the first fan blade structure and the second fan blade structure.

[0016] The beneficial effects of the present invention are: by setting a first reinforcing rib and a second reinforcing rib on the fan blade structure, the present invention improves the overall strength of the fan lamp. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] In the description of this invention, it should be understood that the terms "above," etc., indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element present. Unless otherwise defined, the terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are only used to distinguish different components.

[0042] Please see Figures 1 to 5 As shown, this is the fan blade structure 100 of the present invention. This fan blade structure 100 can be applied to products such as electric fans and fan lights. The fan blade structure 100 is a component used to propel airflow in these products. It can rotate at high speed around its own axis of rotation to propel the surrounding airflow, thereby achieving a blowing effect. To further improve the overall performance of the fan blade structure 100, such as increasing wind power and improving structural strength, the embodiments of the present invention mainly improve the shape of the fan blade structure 100. Compared with traditional fan blade structures, the fan blade structure 100 in the embodiments of the present invention has better blowing effect and structural strength.

[0043] This invention will use a fan light as an example to describe in detail the structure of the fan light, its fan blade structure 100, working principle, and process. Of course, the fan blade structure 100 of this invention can also be applied to other air-blowing products, and no further limitations are imposed here.

[0044] Define the windward side of the fan blade structure 100 as the inner side and the leeward side as the outer side. In this embodiment of the invention, the fan blade structure 100 includes a fan blade body 1, which includes a first side 11 on the windward side, a second side 12 on the leeward side, and a third side 13 connecting the first side 11 and the second side 12. The first side 11, the second side 12, and the third side 13 are all curved edges. When the fan blade structure 100 rotates, the first side 11 on the inner side first contacts the airflow, and then the airflow flows from the first side 11 to the second side 12 on the outer side until it leaves the fan blade structure 100.

[0045] Please see Figure 1 and Figure 2As shown, the end of the fan blade body 1 closest to the third side 13 is defined as the fan blade tip 1a, and the end of the fan blade body 1 furthest from the third side 13 is defined as the fan blade root 1b. The third side 13 connects between the first side 11 and the second side 12 and is located at the fan blade tip 1a. The fan blade body 1 also includes a guide portion 14 connecting the first side 11 and the second side 12, and the first side 11, the second side 12, and the third side 13 are seamlessly connected to jointly enclose the outer peripheral edge constituting the guide portion 14. In other words, the first side 11 and the second side 12 are located on both sides of the width direction of the fan blade structure 100, and the guide portion 14 connects between the first side 11 and the second side 12.

[0046] Preferably, the first side 11 is arranged in a concave arc shape, and the second side 12 and the third side 13 are both arranged in an outward convex arc shape. In other words, the first side 11 and the second side 12 each convex towards the leeward side, so that the two ends of the fan blade structure 100 are located on the front side in its length direction, and the middle area is located on the rear side. With this arrangement, when the fan blade structure 100 rotates at high speed, the fan blade structure 100 can withstand the violent impact from the airflow and is not easy to deform or bend, thereby improving the overall strength and stability of the fan blade structure 100 and thus extending the service life of the fan blade structure 100.

[0047] Overall, the horizontal height of both the first side 11 and the second side 12 gradually increases from the blade root 1b towards the blade tip 1a, and the horizontal height of the second side 12 is lower than that of the first side 11. This causes the guide section 14 to smoothly curve downwards from the first side 11 to the second side 12, resulting in a fan blade structure 100 with a higher windward side and a lower leeward side. Thus, when the fan blade structure 100 rotates at high speed, the airflow enters the guide section 14 from the first side 11, and after being guided by the guide section 14, flows out of the fan blade structure 100 via the second side 12, thereby changing the airflow direction, improving the catching effect, and thus enhancing the blowing effect of the fan blade structure 100.

[0048] Furthermore, the first side 11 extends smoothly upwards from the blade root 1b toward the blade tip 1a, meaning that the two ends of the first side 11 along its length are not on the same horizontal plane. The structural design of the second side 12 is the same as that of the first side 11. This makes the height of the entire blade root 1b lower than the height of the blade tip 1a. On the one hand, this can effectively improve the direction of airflow, thereby achieving a better blowing effect. On the other hand, during the retraction of the blade structure 100, adjacent blade structures 100 are staggered and do not overlap when viewed from above, meaning that the orthographic projections of adjacent blade structures 100 on the horizontal plane do not overlap. The side of the second side 12 of the first fan blade structure 100 near the end 1a of the fan blade is opposite to the side of the first side 11 of the second fan blade structure 100 near the root 1b of the fan blade. That is, the end 1a of the fan blade of the first fan blade structure 100 is located on the inner side of the front side of the root 1b of the fan blade of the adjacent second fan blade structure 100, and there is a gap between the two, so that the fan blade structure 100 can freely extend, retract and rotate, and it is also conducive to the miniaturization of the fan light 200 product.

[0049] The highest point of the fan blade structure 100 is located at the end of the first side 11 near the fan blade tip 1a, and the lowest point of the fan blade structure 100 is located at the end of the second side 12 near the fan blade root 1b. The distance between the highest point of the fan blade structure 100 and the fan blade root 1b accounts for 50% to 75% of the total length of the fan blade structure 100, preferably two-thirds. The height of the highest point of the fan blade structure 100 relative to the horizontal plane where the fan blade root 1b is located ranges from 45mm to 115mm, preferably 90mm. Furthermore, the horizontal plane where the lowest point of the fan blade structure 100 is located is flush with the horizontal plane where the fan blade root 1b is located. This improves the airflow efficiency of the fan blade structure 100, thereby increasing the air volume.

[0050] In addition, the linear velocity at the blade root 1b is relatively high, while the linear velocity at the blade tip 1a is relatively low. In some embodiments, the blade body 1 is gradually widened from the blade root 1b to the blade tip 1a. On the one hand, this can improve the strength and stability of the entire blade body 1, enabling it to withstand greater centrifugal forces without deformation or damage, thus ensuring the normal use of the blade structure 100. On the other hand, it can, to a certain extent, allow more air to flow with the blade body 1 at a greater speed, thereby increasing the wind power of the blade structure 100. In other embodiments, the width of the blade body 1 can be set to a constant value in the direction from the blade root 1b to the blade tip 1a, i.e., the distance from the first side 11 to the second side 12 remains unchanged.

[0051] Please see Figure 2As shown, the first side 11 has a first end near the blade root 1b and a second end connected to the third side 13. The radius of curvature of the first side 11 decreases and then increases from the first end to the second end. The radius of curvature of the second side 12 exhibits a regular trend of first increasing and then decreasing, thus maintaining the curved shape of the second side 12. The third side 13 has a flow guiding function, which can reduce the resistance of the blade structure 100 to the airflow, thereby reducing energy consumption and noise. The third side 13 has a third end connected to the first side 11 and a fourth end connected to the second side 12. The radius of curvature of the third side 13 gradually increases from the third end to the fourth end. In summary, the changing trends of the radii of curvature of the first side 11 and the third side 13 enable the blade structure 100 to reduce the airflow impact it experiences during operation, thereby improving its overall strength.

[0052] Furthermore, the connection between the third side 13 and the second side 12 forms an acute angle structure 15. On the one hand, this reduces the mass of the blade tip 1a, which is beneficial to the stability of the blade body 1 during high-speed rotation. On the other hand, the acute angle structure 15 can disperse the eddy currents at the blade tip 1a, which is beneficial for noise reduction. The specific angle of the acute angle structure 15 can be set according to actual needs, and no further restrictions are imposed here.

[0053] Please see Figure 4 As shown, specifically, the first side 11 is composed of a first arc segment 111, a fourth arc segment 112, a second arc segment 113, and a third arc segment 114 extending from the fan blade root 1b toward the third side 13. The radius of curvature of the first side 11 gradually decreases from the first arc segment 111 to the second arc segment 113, and gradually increases from the second arc segment 113 to the third arc segment 114. The radius of curvature of the first side 11 is between 55mm and 200mm. Preferably, the radius of curvature of the first side 11 ranges from 62.2mm to 174.8mm. The second arc segment 113 has the smallest radius of curvature at 62.1mm, the first arc segment 111 has the largest radius of curvature at 174.8mm, the third arc segment 114 has a larger radius of curvature than the fourth arc segment 112, and the radius of curvature of the third arc segment 114 is 132.2mm. The radius of curvature of the fourth arc segment 112 is 110.0mm.

[0054] The second side 12 is composed of five arc segments 121, 11th arc segment 122, 6th arc segment 123, 7th arc segment 124, 8th arc segment 125, 9th arc segment 126, and 10th arc segment 127 extending from the blade root 1b toward the blade tip 1a. The radius of curvature of the second side 12 gradually increases from the fifth arc segment 121 to the sixth arc segment 123, and gradually decreases from the sixth arc segment 123 to the seventh arc segment 124. Then, it gradually increases from the eighth arc segment 125 to the ninth arc segment 126, and gradually decreases from the ninth arc segment to the tenth arc segment 127. The radius of curvature of the second side 12 is greater than that of the first side 11, and the radius of curvature of the second side 12 is between 55mm and 200mm. Preferably, the radius of curvature of the second side 12 is the smallest, at 59.8mm, and the radius of curvature of the ninth arc segment 126 is the largest, at 261.0mm.

[0055] The third side 13 is composed of a continuous twelfth arc segment 131 and a thirteenth arc segment 132. The twelfth arc segment 131 is connected to the first side 11, and the thirteenth arc segment 132 is connected to the second side 12. The radius of curvature of the twelfth arc segment 131 is smaller than that of the thirteenth arc segment 132. The radius of curvature of the third side 13 is between 80mm and 400mm. Preferably, the radius of curvature of the twelfth arc segment 131 is 83.75mm, and the radius of curvature of the thirteenth arc segment 132 is 383.31mm.

[0056] By setting the curvature radii of the first side 11, the second side 12, and the third side 13, the wind-catching effect of the fan blade structure 100 is improved, thereby increasing the air volume.

[0057] Please see Figure 5As shown in the embodiment of the present invention, in the width direction of the guide portion 14, the guide portion 14 includes a first cross-section, a second cross-section, and a third cross-section (corresponding to the cross-sections at the first dashed line A, the second dashed line B, and the third dashed line C, respectively) provided from the fan blade root 1b to the fan blade end 1a. That is, the first cross-section, the second cross-section, and the third cross-section are all cross-sections of the guide portion 14 along its width direction. Overall, the lateral radius of curvature of the cross-section of the guide portion 14 gradually decreases from the first side 11 towards the second side 12. In other words, the lateral curvature of the guide portion 14 gradually increases from the first side 11 towards the second side 12, thus achieving a good airflow effect. The longitudinal radius of curvature of the guide portion 14 first gradually decreases, then slightly increases, then slightly decreases again, and then gradually increases again from the fan blade root 1b towards the fan blade end 1a. In other words, the longitudinal curvature of the guide portion 14 first gradually increases, then slightly decreases, then slightly increases again, and then gradually decreases again from the fan blade root 1b towards the fan blade end 1a. This is equivalent to first gradually increasing and then gradually decreasing, and the slight decrease and slight increase processes can be ignored. In this design, the longitudinal direction of the airflow guide 14 is its length direction, and the transverse direction is its width direction. This allows the fan blade structure 100 to achieve better airflow when applied to the fan light 200 product; it also enhances the overall strength of the fan blade structure 100.

[0058] Please see Figure 1 and Figure 2 As shown, the fan blade structure 100 also includes a connecting structure 2, which is fixedly connected to the side of the fan blade root 1b away from the fan blade end 1a. The fan blade body 1 is connected to the fan lamp body 201 through the connecting structure 2. Specifically, the connecting structure 2 is located between the first side 11 and the second side 12, and protrudes from the fan blade root 1b to facilitate its connection with the fan lamp body 201. In some embodiments, the connecting structure 2 and the airflow guide 14 are assembled and fitted together to form a whole; in other embodiments, it can also be manufactured using a one-piece molding process.

[0059] The thickness of the fan blade body 1 gradually decreases from the fan blade root 1b to the fan blade tip 1a, meaning the fan blade root 1b is thicker and the fan blade tip 1a is thinner, with an overall gradual transition in thickness. This enhances the overall strength and stability of the fan blade structure 100, ensuring that the fan blade structure 100 will not deform or bend during high-speed rotation, thus guaranteeing its normal use. The thickness of both the first side 11 and the second side 12 gradually decreases from the fan blade root 1b toward the fan blade tip 1a to form a gradually curved structure. Furthermore, in the width direction of the guide section 14, the thickness of the first side 11 is less than the thickness of the guide section 14, resulting in a wider and gentler airflow area, providing a more comfortable experience and achieving a good wind-cutting effect.

[0060] Please see Figure 3As shown, to further improve the overall strength of the fan blade structure 100, a first reinforcing rib 16 and a second reinforcing rib 3 are also provided on the fan blade structure 100. The first reinforcing rib 16 is located on the airflow guide portion 14 and extends from the fan blade root 1b towards the fan blade tip 1a. The width of the first reinforcing rib 16 gradually decreases, forming a fishbone-like structure. Preferably, the first reinforcing rib 16 is located in the middle region of the airflow guide portion 14 in the width direction. Of course, the specific location and cross-sectional shape of the first reinforcing rib 16 can be further defined according to specific needs, and this invention does not limit this.

[0061] The second reinforcing rib 3 is disposed at the root 1b of the fan blade, and its two ends are respectively connected to the connecting structure 2 and the root 1b of the fan blade to strengthen the connection between the two. Optionally, there are multiple second reinforcing ribs 3, which are arranged in a ring at equal intervals between the connecting structure 2 and the root 1b of the fan blade. The specific number of second reinforcing ribs 3 can be set according to the actual size of the fan blade structure 100, and the present invention does not limit this.

[0062] Please see Figures 6 to 22 As shown, the present invention also discloses a fan light 200, including a fan light body 201 and a plurality of fan blade structures 100, wherein the plurality of fan blade structures 100 are foldable or unfoldable and disposed on the fan light body 201. By providing fan blade structures 100, the overall strength and air blowing effect of the fan light 200 can be improved.

[0063] Please see Figures 8 to 10 and combined Figure 19 As shown, in order to mount the fan blade structure 100 on the turntable 30, the connecting structure 2 of the fan blade structure 100 includes a rotating part 21. The fan lamp body 201 is provided with a turntable 30, and mounting parts 32 are provided at corresponding intervals on the turntable 30. The rotating part 21 is connected to the mounting part 32 by fasteners. In this way, the fan blade structure 100 and the turntable 30 can achieve relative rotation through the cooperation between the rotating part 21 and the mounting part 32. In this embodiment, the fan blade structures 100 are arranged in an alternating manner on the turntable 30, which can make full use of the limited space on the turntable 30, thereby facilitating the miniaturization of the fan lamp 200 product. Moreover, when the fan blade structure 100 is in the retracted state, from the observer's perspective, it can be ensured that the fan blade structure 100 can be blocked by the turntable 30, thereby improving the overall aesthetics of the fan lamp 200.

[0064] In some embodiments, the mounting portion 32 is a groove, the rotating portion 21 is a protrusion, and the fastener is a screw or bolt, etc. In other embodiments, the mounting portion 32 may be replaced by a protrusion, and the rotating portion 21 may be a corresponding groove. It is understood that the number of mounting portions 32 corresponds one-to-one with the number of fan blade structures 100.

[0065] Furthermore, in order to enable the multiple fan blade structures 100 to simultaneously unfold or retract relative to the fan lamp body 201, in this embodiment, the turntable 30 is provided with multiple guide grooves 321 at intervals, and the guide grooves 321 are positioned relative to the mounting portion 32 close to the central axis of the fan lamp body 201. The connecting structure 2 of the fan blade structure 100 also includes a guide portion 22, which is correspondingly housed in the guide groove 321. That is, the multiple fan blade structures 100 are rotatably and spaced apart on the turntable 30, and the guide portion 22 can slide relative to the guide groove 321, that is, the guide portion 22 can slide from one end of the guide groove 321 to the other end, thereby completing the unfolding and retracting actions of the fan blade structure 100.

[0066] Optionally, the guide portion 22 can be a guide post, guide pin, guide shaft, or other structure that can achieve the same guiding function. The arrangement of multiple guide grooves 321 can realize the synchronous unfolding or synchronous retraction of multiple fan blade structures 100. It can be understood that the number of guide grooves 321 corresponds one-to-one with the number of fan blade structures 100. Preferably, there are three fan blade structures 100. When all three fan blade structures 100 are retracted, the side of the first side 11 of the preceding fan blade structure 100 near the root 1b of the fan blade is opposite to the side of the second side 12 of the following fan blade structure 100 near the tip 1a of the fan blade, and a gap is formed between the preceding fan blade structure 100 and the following fan blade structure 100, so that the three fan blade structures 100 do not overlap.

[0067] Furthermore, the guide groove 321 also functions to limit the rotation angle of the fan blade structure 100 relative to the fan lamp body 201, thereby enabling the fan blade structure 100 to meet the requirements of the unfolded state or the retracted state respectively. Preferably, the guide groove 321 is an arc-shaped groove.

[0068] The turntable 30 can not only install multiple fan blade structures 100, but also enable multiple fan blade structures 100 to complete synchronous unfolding or retracting actions, and limit the rotation angle of the fan blade structure 100, thereby ensuring the normal operation of the fan light 200.

[0069] The fan light body 201 also includes a lighting component, a drive unit 31 connected to the turntable 30, and a suspension component. The lighting component includes a chassis 40, a light source module 41 integrated on the chassis 40, a drive module 42 electrically connected to the light source module 41, and a mask 43 fixedly connected to the chassis 40. The chassis 40 and the mask 43 together form a receiving cavity for accommodating the light source module 41 and the drive module 42. The mask 43 is configured to emit the emitted light from the light source module 41 to achieve the lighting effect. In this invention, the drive module 42 is preferably integrated on the chassis 40. Of course, the drive module 42 can also be set on the fan blade structure 100 or the suspension component, as long as the drive module 42 can drive the lighting component and the fan blade structure 100.

[0070] The drive unit 31 is configured to drive the turntable 30 to rotate, thereby causing the fan blade structure 100 to open or close relative to the turntable 30. The suspension assembly includes a ceiling mount 50 and a hanging rod 51, one end of which is connected to the drive unit 31 and the other end of which is connected to the ceiling mount 50. The lighting assembly is located below the turntable 30 and is connected to the drive unit 31, and the hanging rod 51 is also connected to the drive unit 31, allowing the lighting assembly to be stably suspended from the roof or other mounting surface.

[0071] Combination Figure 7 , Figure 11 as well as Figure 12 As shown, the cross-section of the fan light 200 of the present invention is circular, therefore its faceplate 43, base 40, and turntable 30 are also circular. The base 40 includes a main body 401 and a protrusion 402 surrounding the outer periphery of the main body 401. A positioning part 403 is provided on the inner sidewall of the protrusion 402. The faceplate 43 is provided with a corresponding mating part 431 that cooperates with the positioning part 403. The mating part 431 is configured to cooperate with the positioning part 403 so that the faceplate 43 and the base 40 are fixedly connected.

[0072] Preferably, the positioning part 403 is configured as a rib protruding towards the center of the chassis 40, and the ribs 403 are evenly distributed on the inner sidewall of the protrusion 402. The mating part 431 is configured to be recessed from the outer sidewall of the face mask 43 towards the center of the face mask 43, thereby fixing the chassis 40 and the face mask 43 by the ribs 403 protruding into the mating part 431. This configuration simplifies the assembly of the face mask 43 and the chassis 40, making the installation of the fan light 200 more convenient.

[0073] like Figures 12 to 15As shown, further, the mating part 431 is arranged around the edge of the face mask 43. The face mask 43 includes a first side wall 4310, a second side wall 4311 disposed opposite to the first side wall 4310, and a connecting wall 4312 connecting the first side wall 4310 and the second side wall 4311. The mating part 431 is formed by the first side wall 4310 and the connecting wall 4312. The first side wall 4310 is received in the receiving cavity and abuts against the upper surface of the rib 403. The rib 403 extends into the mating part 431 and abuts against the connecting wall 4312. The second side wall 4311 abuts against the protrusion 402. This arrangement can reduce the gap between the face mask 43 and the base 40, making it not only difficult to disassemble the base 40 and the face mask 43 after installation, but also preventing mosquitoes from entering the receiving cavity.

[0074] Furthermore, the chassis 40 is also provided with an abutment portion 404, which protrudes toward the face mask 43 and abuts against the inner wall of the connecting wall 4312. The rib 403 and the abutment portion 404 are staggered and press against the connecting wall 4312 in the inward and outward directions. In other words, by using the staggered rib 403 and the abutment portion 404, when assembling the chassis 40 and the face mask 43, the rib 403 and the abutment portion 404 can press against the connecting wall 4312 in the inward and outward directions, further ensuring that the face mask 43 is not easy to fall off the chassis 40. At the same time, it is convenient to assemble the chassis 40 and the face mask 43 on the basis of compression and fixation, and it is not easy to disassemble after assembly.

[0075] Of course, in order to make the connection between the chassis 40 and the mask 43 tighter, the connection between the positioning part 403 and the mating part 431 can be designed as a non-detachable connection. That is, the positioning part 403 and the mating part 431 are used to fix the chassis 40 and the mask 43 together. This not only ensures that the gap between the mask 43 and the chassis 40 is smaller, but also ensures the connection stability between the components in the lighting assembly. The connection stability between the mask 43 and the chassis 40 will not be affected by human or environmental factors. At the same time, it protects the internal structure of the housing cavity to prevent dust, insects and other pollutants from entering the housing cavity, damaging the luminous efficiency of the light source module 41, damaging the lighting assembly and affecting the service life of the fan light 200.

[0076] Combination Figure 7 , Figure 11 , Figure 16 as well as Figure 17As shown, a receiving groove 405 for housing the drive module 42 is recessed at the middle position of the chassis 40 towards the turntable 30, and this receiving groove 405 communicates with the receiving cavity. The light source module 41 is arranged in a ring shape, and the light source module 41 surrounds the receiving groove 405 and is tightly fixed to the chassis 40; the light source module 41 includes a ring-shaped light source plate 410 and LED light sources 411 evenly distributed on the light source plate 410. This arrangement not only effectively improves the space utilization within the receiving cavity, but also ensures that the drive module 42 does not obstruct the light source module 41.

[0077] Specifically, the drive module 42 includes a circuit board 420 and a cover plate 421 for protecting the circuit board 420. The entire circuit board 420 is placed in the receiving groove 405 and fixedly connected to the chassis 40. The circuit board 420 integrates multiple functional components for adjusting the brightness and temperature of the lighting components, etc. The cover plate 421 is assembled and fixed to the inner wall of the receiving groove 405 to cover and protect the circuit board 420. In this invention, the cover plate 421 is fixed to the inner wall of the receiving groove 405 by a snap-fit ​​connection, but this should not be a limitation, as long as it can achieve the purpose of removing the cover plate 421 from the chassis 40.

[0078] Furthermore, combined Figure 18 As shown, the drive module 42 also includes several wires. A first rack 4210 protrudes from the side of the cover plate 421 facing the circuit board 420. Correspondingly, a second rack 4210' is provided at the center of the chassis 40. When the cover plate 421 and the chassis 40 are snapped together, the first rack 4210 and the second rack 4210' are arranged vertically opposite each other, forming a locking space 4211 between the first rack 4210 and the second rack 4210'. The wires are locked in the locking space 4211 to prevent pulling during wire assembly or use. Preferably, the first rack 4210 is arranged in a ring and located at the center of the cover plate 421, and the second rack 4210' is also arranged in a ring and located at the center of the chassis 40. This allows multiple wires to be concentrated and locked between the first rack 4210 and the second rack 4210' to prevent wire pulling and also facilitates installation.

[0079] Furthermore, a flame-retardant pad 44 is provided between the chassis 40 and the circuit board 420 to prevent the drive module 42 from overheating. The two sides of the flame-retardant pad 44 are fixedly connected to the chassis 40 and the circuit board 420 respectively to prevent the circuit board 420 from spontaneously combusting due to excessive temperature during operation. Of course, if the chassis 40 already contains flame-retardant materials, then the flame-retardant pad 44 may not be provided between the chassis 40 and the circuit board 420. That is, whether or not the flame-retardant pad 44 is provided depends on the specific material of the chassis 40.

[0080] The drive unit 31 is electrically connected to the drive module 42, so that the drive module 42 can provide power to the drive unit 31 or the light source module 41 independently to start the lighting component or fan blade structure 100, or it can provide power to both the drive unit 31 and the light source module 41 simultaneously to start both the lighting component and the fan blade structure 100. This effectively improves the space utilization of the receiving cavity and also effectively reduces the weight of the entire fan light 200. In this embodiment, the drive unit 31 is a DC motor; of course, in other embodiments, the drive unit 31 can also be an AC motor, as long as it can drive the turntable 30 to rotate, and there is no limitation here.

[0081] Combination Figure 7 and Figure 19 As shown, the driving component 31 in this invention is preferably an external rotor motor, which includes a stator and a rotor surrounding the stator. The stator is fixedly connected to the chassis 40, and the rotor is fixedly connected to the turntable 30. Specifically, one end of the external rotor motor is connected to the hanger 51, and the other end passes through the turntable 30 and the chassis 40 respectively, and is fixedly connected to the chassis 40. With this configuration, the turntable 30 can rotate relative to the chassis 40 under the drive of the rotor, so that the fan blade structure 100 on the turntable 30 can unfold or retract. Of course, the driving component 31 can also be a driving component of other structures, as long as it can drive the turntable 30 to rotate relative to the chassis 40, and there are no excessive restrictions. Furthermore, the external rotor motor in this invention is smaller and thinner than traditional motors. With this configuration, when the entire fan light 200 is viewed from a 45° angle, the fan light 200 looks more aesthetically pleasing.

[0082] The fan light 200 of the present invention also includes a temperature sensor 33 for detecting the ambient temperature around the fan light 200. The temperature sensor 33 is fixedly connected to the drive component 31 and is located at one end of the drive component 31 near the hanging rod 51. Preferably, the temperature sensor 33 is a temperature sensor with intelligent control function, used to detect the ambient temperature around the fan light 200 in real time, and control the rotation speed of the fan blade structure 100 in real time according to the current ambient temperature. For example, when the ambient temperature rises, the rotation speed of the fan blade structure 100 increases, and when the ambient temperature falls, the rotation speed of the fan blade structure 100 decreases, thereby achieving the purpose of intelligent control.

[0083] A protective cover 34 is fitted onto the temperature sensor 33. The protective cover 34 is hollow and fixedly connected to the drive component 31 to protect the temperature sensor 33. Of course, the temperature sensor 33 of the present invention can also be set in other locations, as long as it can detect the temperature of the environment around the fan light 200 in real time, and there are no excessive restrictions.

[0084] Combination Figure 7 and Figure 20As shown, a reinforcing part 45 is provided between the chassis 40 and the turntable 30. The reinforcing part 45 is configured to fit against the chassis 40, and the reinforcing part 45 has a fixing part 452, which passes through the chassis 40 and is fixedly connected to the chassis 40.

[0085] like Figures 20 to 22 As shown, specifically, the reinforcing part 45 is located at the middle position of the chassis 40. A first groove 406 with an opening facing the turntable 30 is provided on the side of the chassis 40 near the turntable 30. The reinforcing part 45 is placed inside the first groove 406 and fits against the side wall of the first groove 406. A second groove 407 is recessed at the middle position of the first groove 406. A protrusion 450 corresponding to the second groove 407 is provided at the middle position of the reinforcing part 45, fitting snugly inside the second groove 407. A through hole 451 is formed at the center of the protrusion 450. A corresponding through hole 408 is formed on the chassis 40, corresponding to the through hole 451. A fixing part 452 is formed by tearing on the protrusion 450. Part of the fixing part 452 is located at the edge of the through hole 451, and another part surrounds the side of the through hole 451. These fixing parts 452 all protrude towards the chassis 40 to pass through the through hole 408 and be fixedly connected to the chassis 40.

[0086] A groove 453 opposite to the protrusion 450 is formed on the reinforcing part 45. That is, when the groove 453 is formed by pressing on the reinforcing part 45, the other side of the reinforcing part 45 protrudes outward simultaneously, thus forming the protrusion 450. The driving member 31 passes through the through hole 451 and the through hole 408 in sequence and abuts against the inner wall of the groove 453. With this arrangement, the reinforcing part 45 not only strengthens the structural strength of the chassis 40 to prevent damage to the chassis 40 when the fan blade structure 100 rotates, but also can cooperate and connect with the chassis 40 and the turntable 30 to increase the heat dissipation area between the chassis 40 and the turntable 30.

[0087] To further enhance the structural strength of the chassis 40, a raised rib 454 is formed on the side of the reinforcing part 45 facing the turntable 30. This raised rib 454 is evenly distributed on the reinforcing part 45 and connects the outer wall of the groove 453 to the outer edge of the reinforcing part 45. Furthermore, the reinforcing part 45 is provided with positioning holes 455, and the chassis 40 is provided with corresponding positioning ribs 409 that mate with the positioning holes 455. During assembly, the positioning ribs 409 extend into the positioning holes 455, serving not only as pre-installation but also limiting the shaking between the reinforcing part 45 and the chassis 40. Multiple positioning holes 455 are provided, mainly including round holes and oblong holes 4550. The oblong holes 4550 are primarily designed to prevent tolerance issues during assembly of the reinforcing part 45 and the chassis 40, thereby facilitating assembly between the reinforcing part 45 and the chassis 40.

[0088] Combination Figure 7 , Figure 14 , Figure 19 as well as Figure 20 As shown, an annular groove 40A is formed near the edge of the chassis 40, with the opening of the annular groove 40A facing the turntable 30. The edge of the turntable 30 is provided with a protruding edge 301. After the chassis 40 and the turntable 30 are assembled, the protruding edge 301 is received in the annular groove 40A. Specifically, the annular groove 40A is formed between the body portion 401 and the protrusion 402 of the chassis 40, and the bottom of the annular groove 40A is configured to abut against the second side wall 4311 of the face mask 43. In this invention, the turntable 30 and the base 40 are stacked vertically. The driving component 31 passes through both the turntable 30 and the base 40, fixing the rotor to the turntable 30 and the stator to the base 40. The turntable 30 has a raised edge 301 at its edge, which is housed within an annular groove 40A. This design improves the aesthetics of the assembly between the turntable 30 and the base 40, allows the raised edge 301 to rotate within the annular groove 40A, effectively controlling rotational errors, and also uses the base 40 to shield the turntable 30 from rotation. Thus, the turntable 30, the driving component 31, and the base 40 can be integrated into a single unit, meaning the fan blade structure 100 and the lighting assembly are integrated. Under the driving action of the driving component 31, the turntable 30 can rotate relative to the base 40, thereby causing the fan blade structure 100 to unfold or retract.

[0089] It should be noted that, in addition to the structure described above, the suspension assembly can be configured in other ways with reference to existing technical solutions, and there are no restrictions on the specific structure of the suspension assembly.

[0090] Since the fan blade structure 100 of the present invention has made improvements in shape and radius of curvature, the following description will use the test results of two samples to illustrate the blowing effect of the fan blade structure 100 of the present invention.

[0091] Test results Two identical fan light products 200, with rotational speed as the sole variable, were designated as Sample 1 and Sample 2. In this embodiment of the invention, Sample 1 had a rotational speed of 250 rpm, and Sample 2 had a rotational speed of 260 rpm. Multiple measurement points were defined, and various performance data of Sample 1 and Sample 2, such as test voltage, input power, and energy efficiency value, were tested when they were started. The test results are shown in Table 1. The air blowing effect of Sample 1 and Sample 2 was compared by testing the wind speed at different measurement points, and the test results are shown in Tables 2 and 3, respectively.

[0092] Table 1. Performance data of Sample 1 and Sample 2 during operation. As shown in Table 1, under otherwise identical conditions, since the rotation speed of Sample 1 is lower than that of Sample 2, the total air volume of Sample 1 is slightly lower than that of Sample 2. This indicates that the total air volume is directly proportional to the rotation speed of the fan lamp 200. However, the energy efficiency value of Sample 1 is slightly higher than that of Sample 2, indicating that Sample 1 is more energy-efficient than Sample 2.

[0093] Table 2. Test results of wind speed at different measurement points for Sample 1 Table 3 Wind speed measurement results of Sample 2 at different measurement points Define the side of the test point closest to the fan light 200 as the front side of the test point, and take the center point of the fan light 200 as the center and the distance between the test point and the central axis of the fan light 200 as the radius of the ring, thus forming a ring.

[0094] As shown in Tables 2 and 3, the wind speeds measured at different test points varied. Specifically, overall, the wind speeds at the test points (including those in front, behind, to the left, and to the right of the test point) initially showed a positive correlation with the distance from the test point to the central axis of the fan light 200, followed by a negative correlation. Furthermore, at different annular radii, the direction of the maximum wind speed at the test point exhibited irregular changes, which may be related to factors such as airflow in the actual test environment.

[0095] Furthermore, when the radius of the ring is 200 meters, the average wind speeds of samples 1 and 2 both reach their maximum values, at 182.60 m / min and 182.52 m / min, respectively. When the radius of the ring is 360 meters, the airflow through the ring for samples 1 and 2 both reach their maximum values, at 25.61 m³ / min and 24.97 m³ / min, respectively. This indicates that the fan light 200 has the best blowing effect at a distance of 200 meters from the test point's central axis, while the fan light 200 has the highest airflow through the ring at a distance of 360 meters from the test point's central axis. It can be seen that although the rotational speed of sample 1 is lower than that of sample 2, the average wind speeds and airflow through the ring for samples 1 and 2 are only slightly different. In other words, the fan blade structure 100 of the present invention, due to its improved radius of curvature, achieves better blowing effect even when the rotational speed changes, and is not significantly affected by changes in rotational speed.

[0096] Overall, at a ring radius of 40 meters, the average wind speed and airflow through the ring for sample 1 were slightly higher than those for sample 2. When the ring radius was between 40 and 200 meters, the average wind speed and airflow through the ring for fan light 200 increased with increasing ring radius. When the ring radius was between 200 and 1000 meters, the average wind speed of fan light 200 decreased with increasing ring radius, while the airflow through the ring for fan light 200 first increased and then decreased with increasing ring radius. When the ring radius exceeded 1000 meters, no wind speed was measured at the test point for either sample 1 or sample 2. This is because the flowing air is constantly subjected to resistance during its flow, causing the wind force to gradually weaken and eventually reach zero. At a ring radius of 920 meters, the average wind speed for sample 2 was higher than that for sample 1. This is related to the fact that the rotational speed of sample 2 was higher than that of sample 1, and the influence of airflow in the actual environment was relatively small at this point.

[0097] As mentioned above, the fan light 200 product of the present invention can achieve wide-range airflow and can be applied in large-area places such as workshops and warehouses that require cooling.

[0098] In summary, by improving the shape and radius of curvature of the fan blade structure 100, the present invention improves the overall strength and airflow effect of the fan light 200.

[0099] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
