Description

Ceiling fan light [Technical Field]

[0001] This invention relates to the field of ceiling fans, and more specifically to a ceiling fan light. [Background Technology]

[0002] Currently, ceiling fan lights on the market are ceiling fans with integrated lighting fixtures. The integrated design of the ceiling fan and the light fixture allows the ceiling fan light to meet both the needs of the fan and the lighting function, making it popular in the market.

[0003] However, the existing Chinese utility model patent CN208652471U discloses an easy-to-disassemble ceiling fan light. During the operation of the ceiling fan light, the airflow area diagonally below the ceiling fan light has a better airflow effect than the airflow area vertically below the ceiling fan light. When rotating, due to the airflow distribution of low downward wind force in the middle area and high downward wind force in the edge area, the wind force felt by the user directly below the ceiling fan light is very weak. Therefore, the wind force of the ceiling fan light is insufficient to meet the user's needs.

[0004] Furthermore, a Chinese utility model patent CN214998434U discloses a multi-layered fan blade airflow compensation structure. In this prior art, the active impeller and the compensation impeller are fixedly connected to a transmission shaft, and the driving method between them is that a motor drives the transmission shaft, which in turn drives the active impeller and the compensation impeller to rotate together. The compensation impeller in this prior art is essentially a proportionally scaled-down active impeller structure. It rotates together with the active impeller and is equivalent to a part of the active impeller. It cannot effectively act on the corresponding air area to enhance airflow, so the effect of compensating for airflow is very weak.

[0005] In view of the above-mentioned technical problems, this invention is proposed. [Summary of the Invention]

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a ceiling fan light. By incorporating an auxiliary fan blade assembly, an external rotor motor drives the main fan blade assembly and the auxiliary fan blade assembly to rotate simultaneously. The rotation of the main fan blade assembly disturbs the airflow in the outer airflow zone A, while the rotation of the auxiliary fan blade assembly disturbs the airflow in the inner airflow zone B. This strengthens the vertical downward flow of air in the inner airflow zone B, solving the problem of insufficient airflow in existing ceiling fan lights. The ceiling fan light of this application has the advantage of enhancing the vertical downward flow of airflow.

[0007] This invention is achieved through the following technical solution:

[0008] This invention proposes a ceiling fan light, including an external rotor motor, a main fan blade assembly, an auxiliary fan blade assembly, and a mounting assembly. The external rotor motor includes a rotor assembly and a stator assembly. The main fan blade assembly is connected to the upper part of the rotor assembly, and the mounting assembly is connected to the stator assembly. An outer airflow zone A is formed axially and obliquely downward of the main fan blade assembly, which can disturb the airflow. An inner airflow zone B is formed directly below the main fan blade assembly. An auxiliary fan blade assembly is connected to the lower part of the rotor assembly and located below the main fan blade assembly. The auxiliary fan blade assembly is configured to rotate with the main fan blade assembly and the rotor assembly to enhance the vertical downward flow of the airflow disturbed in the inner airflow zone B.

[0009] The ceiling fan light also includes a lamp holder, which includes a lamp base connected to the stator assembly, a light source for illumination disposed within the lamp holder, and a lamp shade that is detachably connected to the lamp holder.

[0010] As described above, the ceiling fan light assembly includes a mounting base connected to the ceiling, a housing disposed below the mounting base, and a suspension rod disposed between the mounting base and the housing.

[0011] As described above, in a ceiling fan light, the rotor assembly includes a rotating shell. The upper end of the rotating shell is fixedly connected to the main fan blade assembly, and the lower end of the rotating shell is fixedly connected to the auxiliary fan blade assembly. The outer rotor motor drives the rotating shell to rotate, thereby causing the main fan blade assembly to rotate to disturb the airflow in the outer airflow zone A, and to drive the auxiliary fan blade assembly to rotate to disturb the airflow in the inner airflow zone B.

[0012] As described above, the auxiliary fan blade assembly includes an annular plate connected to the lower part of the external rotor motor. The annular plate has several ventilation holes for airflow. The auxiliary fan blade assembly also includes a blade group, which consists of several thin blades evenly spaced around the outer edge of the annular plate. The cross-section of the thin blades is arc-shaped.

[0013] As described above, the ceiling fan light has two sets of blades, which are distributed on both sides of the annular plate.

[0014] As described above, in a ceiling fan light, the thin blades in the two sets of blades are staggered relative to each other.

[0015] As described above, the ceiling fan light also has a reinforcing plate in the middle of the blade assembly to strengthen the connection strength of the thin blade structure.

[0016] As described above, the blade assembly also includes a flange for connecting the ends of several thin blades together to strengthen the structural connection of the blade assembly.

[0017] As described above, the main fan blade assembly includes a positioning plate disposed between the mounting assembly and the external rotor motor. The main fan blade assembly is relatively fixedly connected to the upper end of the rotating housing of the external rotor motor through the positioning plate.

[0018] As described above, in a ceiling fan light, the auxiliary fan blade assembly is located below the main fan blade assembly, and there is a gap between the auxiliary fan blade assembly and the main fan blade assembly to form an airflow channel.

[0019] Compared with the prior art, the ceiling fan light of the present invention has the following advantages:

[0020] 1. This invention drives an external rotor motor to rotate, which in turn drives the rotor assembly of the external rotor motor to rotate, so that the main fan blade assembly and the auxiliary fan blade assembly rotate in tandem with the rotor assembly. Compared with the single-layer fan blade structure used in the ceiling fan light in the prior art, in this embodiment, the rotation of the main fan blade assembly disturbs the airflow gathered in the outer airflow zone A to flow downward, while the auxiliary fan blade assembly disturbs the airflow gathered in the inner airflow zone B to flow vertically downward, thereby enhancing the airflow and allowing the user to feel the increase in air volume even when located below the inner airflow zone B.

[0021] 2. The technical solution of the present invention has a flange portion on the auxiliary fan blade assembly. The flange portion connects several thin blades of the blade group into one piece, which strengthens the strength of the auxiliary fan blade assembly. During the long-term operation of the ceiling fan light, it can reduce the risk of thin blades falling off due to aging of the auxiliary fan blade assembly, and has the beneficial effect of strengthening the structure.

[0022] 3. In this invention, the fan blades and blade sheaths of the main fan blade assembly are connected to the rotating housing via positioning plate screws and rotate with the housing. This contrasts with existing technologies where the fan blades and blade sheaths are directly connected to the rotor. Since ceiling fans rotate rapidly during operation, this can easily accelerate the damage to the blade sheath connection over time. In comparison, the technical solution of this application ensures stable rotation of the fan blades in the main fan blade assembly, reduces blade sheath damage, and lowers maintenance costs. Furthermore, the screw connection between the main fan blade assemblies allows for detachment, saving space and reducing packaging and transportation costs, making assembly and disassembly convenient. Moreover, the positioning plate is manufactured as a single piece with uniform thickness, increasing structural stability and reducing production costs.

[0023] 4. In this invention, the light source in the lamp is located below the auxiliary fan blade assembly. Due to the compact structure of the auxiliary fan blade assembly and the structural feature of the blade group being housed within the annular plate, the swaying shadow caused by the rotation of the auxiliary fan blade assembly is avoided during the lighting process of the ceiling fan light.

[0024] 5. In this invention, the stator assembly is used to connect the lamp and the hanging assembly through corresponding flange components, so that the lamp does not rotate during the operation of the ceiling fan light, that is, the area illuminated by the light source does not shake, thus protecting the user's eye health.

[0038] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0039] As shown in Figures 1-11, the present invention includes a ceiling fan light, comprising an external rotor motor 4, a main fan blade assembly 3, an auxiliary fan blade assembly 5, and a mounting assembly 1. The external rotor motor 4 includes a rotor assembly 41 and a stator assembly 42. The main fan blade assembly 3 is connected to the upper part of the rotor assembly 41, and the mounting assembly 1 is connected to the stator assembly 42. The main fan blade assembly 3 forms an outer airflow zone A that can be disturbed by the main fan blade assembly 3 at an axially oblique downward direction. An inner airflow zone B is formed directly below the main fan blade assembly 3. The auxiliary fan blade assembly 5 is connected to the lower part of the rotor assembly 41 and is located below the main fan blade assembly 3. The auxiliary fan blade assembly 5 is configured to rotate with the main fan blade assembly 3 along with the rotor assembly 41 to enhance the vertical downward flow of the disturbed airflow in the inner airflow zone B. The mounting assembly 1 includes a mounting base 11 connected to the ceiling, a cover 13 disposed below the mounting base 11, and a suspension rod 12 disposed between the mounting base 11 and the cover 13.

[0040] The ceiling fan light also includes a lamp 6, which includes a lamp holder 61 connected to the stator assembly 42, a light source 62 disposed in the lamp holder 61 for illumination, and a lamp cover 63 detachably connected to the lamp holder 61.

[0041] In this embodiment, the external rotor motor 4 is driven to rotate, which in turn drives the rotor assembly 41 of the external rotor motor 4 to rotate. Subsequently, the main fan blade assembly 3 and the auxiliary fan blade assembly 5 rotate in tandem with the rotor assembly 41. Compared with the single-layer fan blade structure used in the ceiling fan light in the prior art, in this embodiment, the rotation of the main fan blade assembly 3 disturbs the airflow gathered in the outer airflow zone A to flow downward, while the auxiliary fan blade assembly 5 disturbs the airflow gathered in the inner airflow zone B to flow vertically downward, thereby enhancing the airflow and allowing the user to feel the increase in air volume even when located below the inner airflow zone B.

[0042] In addition, the hanging assembly 1 described in this embodiment includes a mounting base 11 connected to the ceiling, a cover 13 located below the mounting base 11, and a suspension rod 12 located between the mounting base 11 and the cover 13. This ensures that the ceiling fan light maintains a certain distance from the ceiling, preventing the ceiling from being too close to the main fan blade assembly 3 and the auxiliary fan blade assembly 5, thus ensuring that the airflow on the leeward side of the ceiling fan light is not affected. Simultaneously, it ensures that the height of the ceiling fan light from the ground meets installation standards, avoiding obstruction of downward airflow and reduction in air volume.

[0043] Furthermore, the ceiling fan light involved in this technical solution also includes a lamp fixture 6, which includes a lamp holder 61 connected to the stator assembly 42, a light source 62 disposed within the lamp holder 61 for illumination, and a lamp shade 63 detachably connected to the lamp holder 61. This technical solution combines the functions of a ceiling fan in promoting airflow with the functions of a lamp fixture 6 for illumination, thus providing both ventilation and lighting functions.

[0044] As shown in Figures 1, 2, and 4, as a further embodiment, the rotor assembly 41 includes a rotating shell 411. The upper end of the rotating shell 411 is fixedly connected to the main fan blade assembly 3, and the lower end of the rotating shell 411 is fixedly connected to the auxiliary fan blade assembly 5. The outer rotor motor 4 drives the rotating shell 411 to rotate, thereby causing the main fan blade assembly 3 to rotate to disturb the airflow in the outer airflow zone A, and to drive the auxiliary fan blade assembly 5 to rotate to disturb the airflow in the inner airflow zone B.

[0045] This application drives the rotating housing 411 of the external rotor motor 4. The upper end of the rotating housing 411 is locked with screws to the main fan blade assembly 3, and the lower end of the rotating housing 411 is locked with screws to the auxiliary fan blade assembly 5, so that the main fan blade assembly 3 and the auxiliary fan blade assembly 5 rotate together with the rotor assembly 41, thereby disturbing the airflow in the outer airflow zone A and the inner airflow zone B, thus enhancing the airflow effect.

[0046] As shown in Figures 5-8, as a further embodiment, the auxiliary fan blade assembly 5 includes an annular plate 51 connected to the lower part of the external rotor motor 4. The annular plate 51 has a plurality of ventilation holes 52 for airflow. The auxiliary fan blade assembly 5 also includes a blade group 55, which is composed of a plurality of thin blades 53 that are equally spaced and distributed around the outer edge of the annular plate 51. The cross-section of the thin blades 53 is arc-shaped.

[0047] In this technical solution, the auxiliary fan blade assembly 5 is screwed to the lower end of the rotating housing 411 via the annular plate 51. The auxiliary fan blade assembly 5 rotates with the rotating housing 411 to disturb the airflow gathered in the inner airflow zone B, enhancing the vertical downward flow of the airflow in the inner airflow zone B formed directly below the ceiling fan. Furthermore, during the operation of the ceiling fan light, the rapid rotation of the outer rotor motor 4 easily leads to overheating, which will reduce the lifespan of the ceiling fan light over time. In this embodiment, by opening ventilation holes 52 in the annular plate 51, airflow flows through the ventilation holes 52 to carry away the heat generated by the rotation of the outer rotor motor 4, achieving a heat dissipation effect and extending the lifespan of the ceiling fan light.

[0048] As shown in Figures 5 and 6, in a further preferred embodiment, the blade group 55 is provided in two sets, which are respectively distributed on both sides of the annular plate 51. The two sets of blade groups 55 always cover the outer rotor motor 4. The height of the auxiliary fan blade assembly 5 is configured to be less than the height of the rotor assembly 41. This technical solution, by setting two sets of blade groups 55, disturbs more airflow in the surrounding area. During rotation, it strengthens the disturbance of the airflow gathered in the inner airflow zone B by the auxiliary fan blade assembly 5, so that the airflow flows vertically downward.

[0049] As shown in Figure 7, in another preferred embodiment, the blade assembly 55 is further provided with a reinforcing plate 54 in the middle to strengthen the structural connection strength of the thin blade 53. Both blade assemblies 55 always cover the outer rotor motor 4. The height of the auxiliary fan blade assembly 5 is configured to be less than the height of the rotor assembly 41. This technical solution enhances the structural stability of the auxiliary fan blade assembly 5 by providing the reinforcing plate 54 to strengthen the structural connection strength of the thin blade 53.

[0050] As shown in Figure 8, in another preferred embodiment, the blade assembly 55 always covers the outer profile of the outer rotor motor 4, and the height of the auxiliary fan blade assembly 5 is configured to be less than the height of the rotor assembly 41. This technical solution strengthens the structural connection strength of the thin blade 53 by setting a reinforcing plate 54, thereby enhancing the stability of the auxiliary fan blade assembly 5 structure.

[0051] As shown in Figures 5-8, in this embodiment, the thin blades 53 in the two sets of blade groups 55 are staggered relative to each other. This allows the two sets of blade groups 55 to enhance the disturbance of more airflow, while simultaneously increasing the stability of the auxiliary fan blade assembly 5 structure.

[0052] As shown in Figures 5-8, as a further technical solution of the embodiment, the blade assembly 55 also includes a flange 56 for connecting the ends of several thin blades 53 together to strengthen the structural connection strength of the blade assembly 55. The auxiliary fan blade assembly 5 connects several thin blades 53 of the blade assembly 55 together by providing the flange 56, thereby strengthening the auxiliary fan blade assembly 5. During long-term operation of the ceiling fan light, this reduces the risk of the thin blades 53 falling off due to aging, thus having the beneficial effect of strengthening the structure.

[0053] As shown in Figures 1-9, as a further embodiment, the main fan blade assembly 3 includes a positioning plate 2 disposed between the hoisting assembly 1 and the external rotor motor 4. The main fan blade assembly 3 is relatively fixedly connected to the upper end of the rotating housing 411 of the external rotor motor 4 via the positioning plate 2. In this invention, the fan blades and blade sheaths of the main fan blade assembly 3 are screwed to the rotating housing 411 via the positioning plate 2 and rotate with the rotating housing 411. Compared with the prior art where the fan blades and blade sheaths are directly connected to the rotor, the rapid rotation of the ceiling fan during operation can easily accelerate the damage to the blade sheath connection strength over time. In contrast, the technical solution adopted in this embodiment can make the fan blades of the main fan blade assembly 3 rotate stably, while reducing blade sheath damage and lowering maintenance costs. The main fan blade assemblies 3 are connected by screws to achieve a detachable design, which has the advantages of saving space and reducing packaging and transportation costs during packaging and transportation, and makes the disassembly and assembly process convenient.

[0054] In addition, the positioning plate 2 is made of steel or aluminum through a one-piece stamping process. The positioning plate 2 produced by one-piece processing has a uniform thickness, which can increase the structural stability of the positioning plate 2 and reduce the production cost. Secondly, the positioning plate 2 can also be made of low-cost plastic material through one-piece molding, which has the advantage of reducing maintenance costs.

[0055] As shown in Figures 9 and 10, as a further embodiment, the auxiliary fan blade assembly 5 is located below the main fan blade assembly 3, and there is a gap between the auxiliary fan blade assembly 5 and the main fan blade assembly 3 to form an airflow channel. In this technical solution, the airflow gathered in the inner airflow zone B includes a portion of the airflow generated during the disturbance of the main fan blade assembly 3, and it converges through the airflow channel between the main fan blade assembly 3 and the auxiliary fan blade assembly 5, thereby increasing the air intake of the auxiliary fan blade assembly 5. Subsequently, the rotation of the auxiliary fan blade assembly 5 increases the downward flow of the disturbed airflow, and at the same time, it allows the heat generated by the external rotor motor 4 to exchange heat with the outside air, thus playing a heat dissipation role.

[0056] As shown in Figures 1, 2, 10, and 11, as a further solution of this embodiment, in this technical solution, the light source 62 in the lamp 6 is located below the auxiliary fan blade assembly 5. Due to the compact structure of the auxiliary fan blade assembly 5 and the structural features of the blade group 55 being housed within the annular plate 51, the swaying shadow caused by the rotation of the auxiliary fan blade assembly 5 is avoided during the illumination process of the ceiling fan light 6.

[0057] As shown in Figures 1, 2, and 4, as a further embodiment, the upper part of the stator assembly 42 is fixedly connected to the hanging assembly 1, and the lower part is fixedly connected to the lamp 6. In this technical solution, the stator assembly 42 connects the lamp 6 and the hanging assembly 1 via corresponding flange components, ensuring that the lamp 6 does not rotate during operation, i.e., the illumination area of ​​the light source 62 does not shake, thus protecting the user's eye health.

[0058] As shown in Figure 4, as a further embodiment, the stator assembly 42 includes a hollow shaft core 421. A wire for transmitting electrical energy is sleeved inside the shaft core 421. A wire-passing hole 422 is provided on the side wall of the shaft core 421. The wire on the upper side wall of the shaft core 421 is electrically connected to the external rotor motor 4 through the wire-passing hole 422, and the wire at the bottom end of the shaft core 421 is electrically connected to the light source 62 through a lamp holder 61. It should be noted that the wires mentioned in this embodiment are not shown in the figures.

[0059] In addition, this technical solution runs the wires inside the core 421, which can avoid the wires from crossing and getting tangled, as well as malfunctions caused by wire aging or damage, thus enhancing the safety of the circuit. At the same time, it can reduce exposed wires and improve the aesthetics of the ceiling fan light.

[0060] As shown in Figure 3, in a preferred embodiment of this technical solution, a protrusion 611 is formed at the inner edge of the lamp holder 61, and a corresponding groove 631 is provided on the outer edge of the lamp cover 63 for the protrusion 611 of the lamp holder 61 to enter and exit. The groove 631 extends to form a guide groove 632, and a receiving groove 634 for receiving the protrusion 611 is formed at the end of the guide groove 632. A positioning part 633 for limiting the protrusion 611 of the lamp holder 61 within the receiving groove 634 is provided between the receiving groove 634 and the guide groove 632.

[0061] When assembling the lamp holder 61 and the lamp cover 63, support the lamp cover 63 by hand, align the recess 631 of the lamp cover 63 with the protrusion 611 of the lamp holder 61, so that the protrusion 611 slides from the recess 631 into the guide groove 632. When the protrusion 611 slides to the receiving groove 634 at the end of the guide groove 632, the positioning part 633 restricts the protrusion 611 in the receiving groove 634. Release the lamp cover 63, at this time the upper end surface of the receiving groove 634 of the lamp cover 63 and the upper end surface of the protrusion 611 are in contact to complete the assembly. The assembly of the lamp holder 61 and the lamp cover 63 is achieved by the downward action of the lamp cover 63's own weight.

[0062] When disassembling the lampshade 63, support the lampshade 63 by hand and slide it upwards to release the positional relationship between the protrusion 611 and the receiving groove 634. Then, rotate the lampshade 63 along the direction of the guide groove 632 to remove the protrusion 611 from the positioning part 633 and slide it into the guide groove 632. The protrusion 611 then exits the recess 631 along the guide groove 632, thus separating the lampshade 63 from the lamp holder 61. When the user encounters a malfunction in the lamp 6 during use, the above-mentioned technical means can be used to assemble or disassemble the lamp holder 61 and the lampshade 63, thereby facilitating maintenance or replacement of the light source 62. The operation is simple.

[0063] In another preferred embodiment of this technical solution, the outer edge of the lamp holder 61 is provided with a threaded portion, and the inner side of the lampshade 63 is correspondingly provided with an internal thread that engages with the lamp holder 61. When assembling the lamp holder 61 and the lampshade 63, the lampshade 63 is held by hand and screwed along the thread in one direction to a specific position to lock the lampshade 63 onto the lamp holder 61, thus completing the assembly. Conversely, when it is necessary to disassemble the lampshade 63, it is screwed out in the opposite direction to separate it from the lamp holder 61, thus completing the disassembly. This technical solution uses a threaded connection to lock or unlock, enabling a detachable connection between the lamp holder 61 and the lampshade 63 for maintenance or replacement of the light source 62, making operation simple. It should be noted that this embodiment is prior art and is not shown in the figures.

[0064] As shown in Figure 3, the light source 62 is preferably an energy-saving lamp, but it can also be replaced with an incandescent lamp or an LED lamp. Compared with incandescent lamps, the energy-saving lamps used in this technical solution have higher energy efficiency and a relatively longer service life, which can reduce the frequency of replacing the light source 62. In addition, compared with LED lamps, energy-saving lamps are easier to maintain and simpler to operate.
