Description

Technical Field

[0001] This utility model relates to the field of ceiling fan technology, and in particular to a ceiling fan with lighting. Background Technology

[0002] Ceiling fans are fans that are fixedly installed on the ceiling and are very effective at cooling the air. The fan blades are the components of a ceiling fan; they rotate when the fan is running. Some ceiling fans on the market use screws to directly fix the blades together. With this design, most of the stress at the base of the blades is concentrated in the screw holes and screw positions, resulting in uneven stress distribution at the base of the blades and poor overall sturdiness and stability.

[0003] For example, Chinese patent application number CN202322231871.1 discloses a ceiling fan and its blade mounting structure, specifically disclosing that "the mounting disc is provided with blade fixing holes distributed around it; the blades can be fixed to the blade fixing holes by blade fasteners, thereby distributing multiple blades along the outer edge of the mounting disc; during assembly, the motor body can be placed in the cavity of the mounting disc first, then the motor body can be fixed to the cavity by a known method, and then different blades can be fixed to the mounting disc by blade fasteners, thus combining the mounting disc, motor body, and blades into one unit." The fasteners are actually screws, meaning the blades are directly mounted with screws. This results in uneven force distribution at the root of the blades, leading to poor overall stability and robustness.

[0004] For example, the fan blade mounting plate, fan blade mounting structure and ceiling fan disclosed in Chinese patent application number CN201921675047.2 also use screws to directly install the fan blades. This design also has the problem of uneven force distribution at the root of the fan blades and poor overall firmness and stability. Utility Model Content

[0024] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a lighting ceiling fan.

[0025] The root of the fan blade 31 is assembled with the fan blade seat 35 using a fitting and fastener method. This design can improve the firmness and stability between the fan blade 31 and the fan blade seat 35, and the overall force is more balanced.

[0026] This application provides a ceiling fan with lighting, including a suspension device 10, a motor 20, a fan blade assembly 30, and a lighting device 40; the motor 20 includes a stator 22 and a rotor 23; the upper end of the stator 22 is connected to the suspension device 10; the fan blade assembly 30 includes a fan blade seat 35 and a fan blade 31; the fan blade seat 35 is disposed on the rotor 23 and can rotate with the rotor 23; the fan blade seat 35 is provided with a first mounting post 36 and at least three mounting slots 37 arranged at equal angles; the cross section of the mounting slots 37 is stepped; the root of the fan blade 31 is provided with a stepped fitting block 310 and a hollow second mounting post 34; the root of the fan blade is fixed on the fan blade seat 35, the fitting block 310 is embedded in the mounting slot 37, the second mounting post 34 passes through the first mounting post 36, and a first fastener 39 fastens the first mounting post 36 and the second mounting post 34 together; the lighting device 40 includes a lamp housing 41 and a light source disposed in the lamp housing 41. The suspension device 10 is used to install the ceiling fan. The motor 20 is an external rotor 23 type motor. The motor 20 drives the fan blade holder 35 to rotate, and the fan blades are driven to rotate by the fan blade holder 35. There are three mounting slots 37 on the fan blade holder 35. The fan blade holder 35 is fixed to the rotor 23 with screws. When the fan blades are assembled with the fan blade holder 35, the fitting block 310 is embedded into the mounting slot 37, the second mounting post 34 passes through the first mounting post 36, and the first fastener 39 fastens the first mounting post 36 and the second mounting post 34 together. This makes the force at the root of the fan blade more even, and the overall firmness and stability are better. The first fastener 39 is a screw. The second mounting post 34 passes through the first mounting post 36 and is then fixed with fasteners, which also improves the force distribution between the two. The light source in the lamp housing 41 is an LED light source, which can provide illumination. This light source can be powered from the terminal of the stator 22, which is very convenient. The mounting slot 37 is compatible with the structure of the fitting block 310.

[0027] Preferably, the suspension device 10 includes a mounting base 11, a hanging rod 13, a connecting base 14, and a first pin 15. The mounting base 11 has a fitting hole 12 that is larger at the top and smaller at the bottom; the connecting base 14 is fitted into the fitting hole 12; the first pin 15 passes through the upper end of the hanging rod 13 and is secured to the connecting base 14; a second pin 16 passes through the upper end of the stator 22 and the lower end of the hanging rod 13. The suspension device 10 is used to install a ceiling fan. During installation, the hanging rod 13 passes through a first decorative cover 17, and the mounting base 11 is fixed to the ceiling with expansion screws. The connecting base 14 is fitted into the fitting hole 12 on the mounting base 11, the upper end of the hanging rod 13 passes through the connecting base 14, and then the first pin 15 passes through the upper end of the hanging rod 13 and is secured to the connecting base 14, thus fixing the hanging rod 13. Then, the first decorative cover 17 is placed on the mounting base 11 to provide decoration and enhance aesthetics. Of course, the first pin 15 can also be inserted horizontally through the mounting base 11, the hanging rod 13, and the connecting base 14, which can also achieve the installation.

[0028] Preferably, the cross-sections of the fitting hole 12 and the connecting seat 14 are hemispherical; a first decorative cover 17 is fastened to the outside of the mounting base 11, and the first decorative cover 17 covers the mounting base 11. The hemispherical cross-sections of the fitting hole 12 and the connecting seat 14 make the assembly of the connecting seat 14 very simple, preventing it from falling off. The inner wall of the fitting hole 12 has a protrusion, and the outer wall of the connecting seat 14 has an arc-shaped groove. The protrusion is embedded in the groove, which prevents the connecting seat 14 from rotating, resulting in a simple structure.

[0029] Preferably, the motor 20 further includes a housing 21; a first heat dissipation hole 24 is provided on the top of the housing 21; a fan blade seat 35 is provided on the bottom of the housing 21, and a second heat dissipation hole 38 is provided on the fan blade seat 35, the first heat dissipation hole 24 and the second heat dissipation hole 38 being connected. The fan blade seat 35 is fixed to the bottom of the housing 21 with screws. The connection between the first heat dissipation hole 24 and the second heat dissipation hole 38 facilitates the flow of hot air, facilitates heat dissipation of the motor 20, and ensures heat dissipation performance.

[0030] Preferably, the lower end of the suspension rod 13 is provided with a mounting ring 18; the mounting ring 18 is embedded in the top of the second decorative cover 19, and the second decorative cover 19 covers the outer shell 21. The mounting ring 18 can be installed on the suspension rod 13 using a pin. The mounting ring 18 has a certain elasticity and can undergo elastic deformation. The top of the second decorative cover 19 is also provided with a third heat dissipation hole 111, allowing heat to flow from the first heat dissipation hole 24 to the third heat dissipation hole 111. This design facilitates heat dissipation and also prevents dust from entering the motor 20. That is, air can circulate between the first, second, and third heat dissipation holes, facilitating heat dissipation. After the mounting ring 18 is fixed to the suspension rod 13, pressing down on the second decorative cover will cause it to snap onto the mounting ring 18. This assembly structure is simple and will not loosen. The outer wall of the second decorative cover 19 is provided with a light strip groove, and a decorative light strip 110 is provided in the light strip groove. The decorative light strip 110 is an LED light strip, which serves a decorative purpose. The decorative light strip 110 can be powered from the wire.

[0031] Preferably, the lamp housing 41 includes an upper housing 42, a lower housing 46, and a mounting ring 47. The inner circumference of the mounting ring 47 is provided with a fastening step 48 and a first wedge-shaped fastening block 49. The fastening block on the outer circumference of the lower housing 46 fastens to the fastening step 48. The inner circumference of the mounting ring 47 is provided with the first wedge-shaped fastening block 49, and the outer circumference of the upper housing 42 is provided with a second wedge-shaped fastening block 43. The mounting ring 47 is rotatably fastened to the upper housing 42, and the first wedge-shaped fastening block 49 and the second wedge-shaped fastening block 43 are fastened together. The upper housing 42, lower housing 46, and mounting ring 47 are made of plastic. The light source can be fixed inside the upper housing 42 with screws. During assembly of the lamp housing 41, the lower housing 46 is fastened onto the mounting ring 47, causing the fastening blocks to engage with the fastening steps 48. Then, the mounting ring 47 is rotated, causing the first wedge-shaped fastening block 49 and the second wedge-shaped fastening block 43 to engage together. This design simplifies the assembly of the lamp housing 41. Replacing the light source is also very simple; just rotate the housing in the opposite direction. Maintenance is convenient. The upper housing 42 can be fixed to the hanging rod 13 using screws or pins.

[0032] Preferably, the top of the upper shell 42 is provided with a plurality of fourth heat dissipation holes 44, and an arc-shaped guide plate 45 is provided at the outer opening of the fourth heat dissipation hole 44, and a heat dissipation gap is left between the upper shell 42 and the fan blade seat 35. The guide plate 45 can control the direction of heat dissipation inside the lamp housing 41. The heat inside the lamp housing 41 comes out from the fourth heat dissipation holes 44, and then dissipates from the heat dissipation gap between the upper shell 42 and the fan blade seat 35. This design can improve heat dissipation efficiency, speed up heat dissipation, and avoid heat accumulation.

[0033] Preferably, the fan blade holder 35 is a light-guiding fan blade holder 35, and the top surface of the fitting block 310 is a lamp groove, in which a first LED 32 is disposed, and the first LED 32 is connected to the wiring terminal of the rotor 23. The fan blade is a light-guiding fan blade, and several second LEDs 33 are disposed at the root of the fan blade, and the second LEDs 33 are connected to the wiring terminal of the rotor 23; the second LEDs 33 face the end of the fan blade, and the edge of the fan blade is polished to a mirror surface. The fan blade holder 35 and the fan blade are made of light-guiding plastic, such as acrylic, polycarbonate, or thermoplastic polyurethane. The first LEDs 32 and the second LEDs 33 are powered from the wiring terminal of the rotor 23. This design is convenient for power supply and has a simple structure. The fan blade is injection molded, and a groove is provided at the root of the fan blade, in which the second LED is disposed and encapsulated with glue. Preferably, the first LEDs 32 and the second LEDs 33 are integrated on a corresponding control circuit board, and the lights can be controlled wirelessly. The light from the first LED 32 is conducted within the fan blade holder 35 and the fan blade itself, while the light from the second LED 33 is also conducted within the fan blade. This design gives both the fan blade holder 35 and the fan blade a decorative light effect, making them more stylish and aesthetically pleasing. The edges of the fan blades are polished to a mirror finish. This design allows the mirror polishing to create a highly reflective interface at the edge of the light guide plate, significantly improving the light capture rate. When light from a point light source enters at an angle less than the critical angle, the mirror edge can "capture" more than 95% of the light and propagate it along the plate, reducing light escape loss. This design is similar to the total internal reflection effect of optical fibers, ensuring efficient light transmission. Mirror-edge light guide plates can significantly improve overall brightness. For example, a light guide plate with an R-CUT structure can increase brightness by 8%-10% through the synergistic effect of the edge mirror and internal microstructure, while also improving uniformity. In home settings, mirror-edge light guide plates are also commonly used in designs such as floating background walls, enhancing visual depth through edge highlighting. Therefore, the fan blades have a better visual effect.

[0034] In summary, the key design feature of this invention lies in the fact that, during the assembly of the fan blade and the fan blade holder 35, the fitting block 310 at the root of the fan blade is embedded into the mounting groove 37 on the fan blade holder 35, while the second mounting post 34 passes through the first mounting post 36. Then, the first fastener 39 secures the first mounting post 36 and the second mounting post 34 together. The stepped fitting block 310 cooperates with the mounting groove 37; the first mounting post 36, the second mounting post 34, and the first fastener 39 cooperate, making the fan blade installation more secure and stable, and the overall stress distribution more even. Furthermore, because the fitting block 310 is provided at the root of the fan blade, this design also strengthens the structure at the root of the fan blade, resulting in a stronger connection between the fan blade and the fan blade holder 35.
