[0002] The above-mentioned original application claims priority to the Chinese patent application with application number 202211559704.3 filed on December 6, 2022, and invention name “Fan Lamp”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of lighting technology, and in particular to a bladeless fan lamp. Background Art

[0004] A fan light is a household appliance that combines a ceiling lamp and a ceiling fan, providing both lighting and ventilation functions. Users can control the fan light's functions via a remote control. Compared to bladed fan lights, bladeless fan lights have garnered more attention due to their concealed turbine blades, which effectively prevent safety accidents caused by blade detachment.

[0005] In bladeless fan lights, the rotating motor that drives the turbine blades is typically placed on the central axis of the unit. The central portion of the motor serves as the armature core, surrounded by multiple coil windings. The light panel is typically located at the bottom of the unit. Wiring for the panel is routed outside the air duct and secured to the duct's outer wall with cable clips to avoid the turbine blades.

[0006] However, the wiring method of the above-mentioned light panel is complicated and the winding distance is long, resulting in increased material costs. Summary of the Invention

[0062] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0063] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0064] The embodiment of the present application provides a bladeless fan lamp, which is generally used in indoor environments. Figure 1 As shown, the bladeless fan lamp includes a fan mechanism 1 and a lighting mechanism 2; the fan mechanism 1 includes a wind wheel 11 and a rotating motor 12, the wind wheel 11 is driven by the rotating motor 12, and the rotating motor 12 has a hollow shaft 121; the lighting mechanism 2 includes a control component 21, a light-emitting component 22 and a conductive member 23; the control component 21 and the light-emitting component 22 are respectively located on opposite sides of the rotating motor 12, and the conductive member 23 passes through the inside of the hollow shaft 121 and electrically connects the control component 21 and the light-emitting component 22.

[0065] In the bladeless fan lamp provided in the embodiment of the present application, a rotating motor 12 with a hollow shaft 121 is used to drive the wind wheel 11 to rotate, and the control component 21 and the light-emitting component 22 of the lighting mechanism 2 are respectively arranged on opposite sides of the rotating motor 12. In order to transmit electrical signals between the control component 21 and the light-emitting component 22, one end of the conductive member 23 is electrically connected to the control component 21, and the other end passes through the inside of the hollow shaft 121 of the rotating motor 12 and is electrically connected to the light-emitting component 22. Compared with the related art of winding from the outside of the air duct, the solution of this embodiment is to directly pass the wire from the inside of the hollow shaft 121 of the motor, thereby reducing the winding distance of the conductive member 23, effectively reducing the material cost of the conductive member 23, and thus reducing the cost of the bladeless fan lamp. In addition, since the winding distance is short, the wiring is simpler, and it is also possible to avoid the conductive members 23 from being entangled with each other, thereby improving safety.

[0066] In order to make the technical solutions and advantages of the present application clearer, the structures of the various parts of the bladeless fan lamp provided in the embodiment of the present application are further introduced and explained below in conjunction with the accompanying drawings.

[0067] like Figure 2 As shown, an embodiment of the present application provides a bladeless fan lamp, which includes a fan mechanism 1, a lighting mechanism 2 and a suspension mechanism 3.

[0068] The suspension mechanism 3 is typically mounted on the top of the fan mechanism 1 and is used to suspend the bladeless fan light from a mounting surface, such as a ceiling. The fan mechanism 1 and the lighting mechanism 2 provide ventilation and lighting functions, respectively, with the lighting mechanism 2 being mounted on the bottom of the fan mechanism 1. In this embodiment of the present application, the fan mechanism 1 and the lighting mechanism 2 are functionally independent, allowing the user to independently control the fan mechanism 1 and the lighting mechanism 2 to perform their respective functions.

[0069] In the bladeless fan lamp provided in this embodiment, the fan mechanism 1 includes a fan housing 13, a wind wheel 11 located within the fan housing 13, and a rotating motor 12. The fan mechanism 1 achieves its air blowing function through the wind wheel 11. Because the blades 116 of the wind wheel 11 are concealed within the housing, the danger of accidental contact of the exposed blades 116 is avoided, thereby improving safety and security.

[0070] The wind wheel 11 rotates and delivers air under the drive of the rotary motor 12, which has a hollow shaft 121. The hollow shaft 121 is suitable for allowing the conductive member 23 to pass through, so that the conductive member 23 can electrically connect the control component 21 and the light-emitting component 22 of the lighting mechanism 2 in a relatively simple wiring manner. Moreover, since the winding distance of the conductive member 23 is short, it saves materials and reduces costs.

[0071] In the embodiment of the present application, the hollow shaft 121 of the rotating motor 12 may be a stator shaft 1211 or a rotor shaft 1212. The following describes the relevant structures of the bladeless fan lamp for these two possible situations.

[0072] like Figure 3 As shown, in the first possible case, the rotating motor 12 is an outer rotor motor, and the hollow shaft 121 is a stator shaft 1211. The outer rotor motor includes a rotor assembly 122, which surrounds the outer side of the stator shaft 1211 and is connected to the wind wheel 11.

[0073] After the outer rotor motor is started, the hollow stator shaft 1211 remains stationary, while the rotor assembly 122 rotates around the axis of the stator shaft 1211. Driven by the rotor assembly 122, the wind wheel 11 rotates synchronously, generating airflow. In some embodiments, the ends of the hollow stator shaft 1211 extend from opposite sides of the rotor assembly 122 and are respectively connected to the suspension mechanism 3 and the lighting mechanism 2.

[0074] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, the suspension mechanism 3 and the control component 21 are located on the same side of the outer rotor motor, and the suspension mechanism 3 is connected to the stator shaft 1211, and the interior of the suspension mechanism 3 is connected to the interior of the stator shaft 1211; the control component 21 is installed inside the suspension mechanism 3.

[0075] In this bladeless fan lamp, power leads for the outer rotor motor and lighting mechanism 2 are both routed from the suspension mechanism 3, allowing for connection to external circuits embedded in the ceiling. The lighting mechanism 2's control assembly 21 is mounted within the suspension mechanism 3 and electrically connected to the light-emitting assembly 22 via a conductive member 23 to control its illumination.

[0076] See also Figure 6 In some embodiments, the stator shaft 1211 has an external thread 12111 at one end close to the suspension mechanism 3, and the suspension mechanism 3 has an internal thread 31. The stator shaft 1211 and the suspension mechanism 3 are connected by the external thread 12111 and the internal thread 31, and the connection method is simple and reliable.

[0077] In some embodiments of the present application, Figure 7 As shown, the light-emitting assembly includes a light source fixing member 221 and a light-emitting element 222. The light source fixing member 221 is connected to the stator shaft 1211 and is spaced apart from the rotor assembly 122. A through opening 2211 is provided in the middle position of the light source fixing member 221, and the stator shaft 1211 is located in the through opening 2211. The light-emitting element 222 is installed on the side of the light source fixing member 221 facing away from the wind wheel 11.

[0078] The light source fixture 221 can be, for example, a lamp panel. The lamp panel, wind rotor 11, and rotor assembly 122 do not contact each other, so the lamp panel remains stationary when the rotating motor 12 is in operation. A mounting position for a light-emitting element 222 is provided on the side of the lamp panel facing away from the wind rotor 11. Light-emitting element 222, for example, an LED light board, is mounted in a corresponding mounting position on the lamp panel to provide illumination. The conductive member 23 is adapted to connect between the control assembly 21 and the LED light board.

[0079] Alternatively, as Figure 7 As shown, there are multiple light-emitting elements 222, which are symmetrically distributed on the light source fixture 221 to ensure uniform light emission. The multiple light-emitting elements 222 on the light source fixture 221 can be symmetrically arranged, with the axis of symmetry passing through the center point of the light source fixture 221; or they can be centrally symmetrical about the center point of the light source fixture 221. Optionally, multiple LED light panels can be connected in series or in parallel using connecting wires.

[0080] The light source fixing member 221 is directly or indirectly connected to the stator shaft 1211. In some embodiments of the present application, such as Figure 8 As shown, the lighting mechanism 2 further includes a fixing assembly 25, which is connected to the stator shaft 1211 and to the light source fixing member 221. A first opening 2511 is defined on the fixing assembly 25, through which the stator shaft 1211 passes, or through which the conductive member 23 exits from the interior of the stator shaft 1211.

[0081] The fixing assembly 25 is connected to both the light source fixing member 221 and the stator shaft 1211, thereby assembling the light source fixing member 221 to the stator shaft 1211. The fixing assembly 25 does not contact either the rotor assembly 122 or the wind wheel 11. Therefore, when the rotor assembly 122 rotates around the stator shaft 1211, the light source fixing member 221 and the fixing assembly 25 connected to the stator shaft 1211 remain stationary. Exemplarily, the connection between the fixing assembly 25 and the light source fixing member 221 or the stator shaft 1211 includes, but is not limited to, at least one of bolting, threading, clamping, riveting, welding, and interference fit.

[0082] In some embodiments of this application, see Figure 8The fixing assembly 25 may include a connecting member 251 and a fastener 252. The first opening 2511 is located on the connecting member 251. The connecting member 251 is sleeved on the stator shaft 1211 through the first opening 2511 and is connected to the light source fixing member 221. The fastener 252 is engaged with the stator shaft 1211 to fix the connecting member 251 on the stator shaft 1211, wherein the fastener 252 is located on a side of the connecting member 251 away from the rotor assembly 122 and abuts against the connecting member 251; alternatively, the connecting member 251, the light source fixing member 221 and the fastener 252 are arranged in sequence in a direction away from the rotor assembly 122, and the fastener 252 abuts against the light source fixing member 221.

[0083] In one possible scenario, the light source fixing member 221 and the connecting member 251 are fixedly connected, and the connecting member 251 is fastened to the stator shaft 1211 by a fastener 252. For example, the connecting member 251 is sleeved on the stator shaft 1211 through the first opening 2511, and the fastener 252 can abut against the connecting member 251 and cooperate with the stator shaft 1211, thereby fastening the connecting member 251 to the stator shaft 1211; the light source fixing member 221 can be connected to the connecting member 251 by screws.

[0084] In another possible scenario, the light source fixing member 221 and the connecting member 251 abut against each other, and both the light source fixing member 221 and the connecting member 251 are fastened to the stator shaft 1211 by the fastener 252. For example, the connecting member 251 is sleeved onto the stator shaft 1211 through the first opening 2511; the light source fixing member 221 is sleeved onto the stator shaft 1211 through the through opening 2211 and is located on the side of the connecting member 251 away from the rotor assembly 122; the fastener 252 is located on the side of the light source fixing member 221 away from the rotor assembly 122 and abuts against the light source fixing member 221. At this time, under the action of the abutting force of the fastener 252, the light source fixing member 221 and the connecting member 251 also abut against each other. Furthermore, the fastener 252 cooperates with the stator shaft 1211, thereby fastening the connecting member 251 and the light source fixing member 221 to the stator shaft 1211. In this case, the connecting member 251 and the light source fixing member 221 may not be connected to each other to simplify assembly; or the connecting member 251 and the light source fixing member 221 may be connected to each other to improve the fixing reliability and stability of the light source fixing member 221.

[0085] In some embodiments of the present application, the number of connecting members 251 may be more than one, and there are two connecting members 251 among the more than one connecting members 251 that are adjacent to the light source fixing member 221 and are respectively located on opposite sides of the light source fixing member 221, and the light source fixing member 221 is connected to both connecting members 251.

[0086] More than one connecting member 251 is distributed on opposite sides of the light source fixing member 221 and clamps the light source fixing member 221. For example, Figure 9 As shown, there are two connecting members 251, the light source fixing member 221 and the two connecting members 251 are all sleeved on the stator shaft 1211, and the light source fixing member 221 is clamped between the two connecting members 251; the fastener 252 is located on the side of the light source fixing member 221 and the two connecting members 251 away from the rotor assembly 122, abuts against the adjacent connecting members 251, and cooperates with the stator shaft 1211, so that the two connecting members 251 and the light source fixing member 221 are fastened to the stator shaft 1211.

[0087] The light source fixing member 221 is also connected to two adjacent connecting members 251. For example, Figure 9 As shown, a through-hole is provided on the light source fixing member 221, and a through-hole is also provided on each of the two connecting members 251. The through-holes on the light source fixing member 221 correspond to the through-holes on the two connecting members 251. The fastening bolts pass through the three through-holes simultaneously, thereby connecting the light source fixing member 221 and the two connecting members 251. By providing multiple connecting members 251 to sandwich and connect the light source fixing member 221, the connection stability and reliability of the light source fixing member 221 can be improved.

[0088] In some embodiments of the present application, the structure of the rotating motor 12 is as follows: Figure 10 As shown, the rotating motor 12 further includes a stator sleeve 1213, which is connected to the outside of the stator shaft 1211. The stator shaft 1211 extends through the stator sleeve 1213, and the rotor assembly 122 surrounds the outside of the stator sleeve 1213. The stator shaft 1211 extends out of the stator sleeve 1213 and has an external thread 12111 at one end near the light source fixture 221. The fastener 252 is a nut that is threadedly engaged with the stator shaft 1211 to fasten at least one of the connector 251 and the light source fixture 221 between the stator sleeve 1213 and the nut.

[0089] In this embodiment, a portion of the stator shaft 1211 extends out of the stator sleeve 1213, and the connecting member 251, the light source fixing member 221 and the nut are all sleeved on the protruding portion of the stator shaft 1211, and the nut is also threadedly engaged with the external thread 12111 on the stator shaft 1211 through the internal thread 31 to complete the fastening of at least one of the connecting member 251 and the light source fixing member 221 on the stator shaft 1211.

[0090] by Figure 10Taking the structure shown as an example, it should be noted that in this example, the connecting member 251 is fastened between the stator sleeve 1213 and the nut in a clamping manner. When the connecting member 251 is connected, the end of the connecting member 251 away from the nut must be against the stator sleeve 1213, and the other end must be against the nut.

[0091] Figure 11 251 shows a structure of a connecting member. Figure 11 In some embodiments of the present application, the connector 251 includes a connecting plate 2512 and a limiting portion 2513, and the first opening 2511 is located on the connecting plate 2512; the limiting portion 2513 is connected to the side of the connecting plate 2512 close to the rotor assembly 122, and abuts against the stator sleeve 1213, so that there is a distance between the connector 251 and the rotor assembly 122.

[0092] The limiting portion 2513 is used to limit the relative position between the connecting member 251 and the rotor assembly 122. Figure 11 As shown, the limiting portion 2513 abuts against the stator sleeve 1213, so that the portion of the connecting member 251 other than the limiting portion 2513 is away from the rotor assembly 122; although the distance between the limiting portion 2513 and the rotor assembly 122 is relatively close, since it abuts against the stator sleeve 1213, it will not contact the rotor assembly 122, so that the connecting member 251 as a whole does not contact the rotor assembly 122, avoiding friction and mutual influence between the rotor assembly 122.

[0093] In the embodiment of this application, combined with Figure 8 and Figure 11 As shown, the connecting plate 2512 is connected to the light source fixing part 221. In the axial direction of the stator shaft 1211, the distance between the light source fixing part 221 and the rotor assembly 122 is greater than the distance between the limiting portion 2513 and the rotor assembly 122, thereby ensuring that the light source fixing part 221 and the rotor assembly 122 are always non-contact, thereby avoiding mutual influence between the light source fixing part 221 and the rotatable rotor assembly 122.

[0094] In the embodiment of the present application, the limiting portion 2513 can be of any shape and connected to any position on the side of the connecting plate 2512 facing the rotor assembly 122, as long as the distance between the part of the connecting member 251 other than the limiting portion 2513 and the rotor assembly 122 can be increased.

[0095] Alternatively, as Figure 11As shown, the limiting portion 2513 can be arranged around the first opening 2511, and the stator shaft 1211 passes through the limiting portion 2513. In this case, the end surface of the limiting portion 2513 away from the connecting plate 2512 is an annular end surface, which is suitable for abutting the annular end surface of the stator sleeve 1213 and has good stability. In addition, because the stator shaft 1211 passes through the inner side of the annular end surface, it can play a certain limiting role. Therefore, the connector 251 is not easily distorted under the action of the abutting force, thereby improving the reliability of the abutting fit.

[0096] In some embodiments, the connecting plate 2512 has a recessed portion 25121 located in the central area, and the recessed portion 25121 is farther away from the outer rotor motor than other portions of the connecting plate 2512; the first opening 2511 can be opened at the center of the recessed portion 25121, and when the limiting portion 2513 surrounding the first opening 2511 abuts against the stator sleeve 1213, the forces on various portions of the connecting plate 2512 are relatively balanced.

[0097] In some embodiments, see Figure 12 The limiting portion 2513 can be connected to the edge of the first opening 2511 and cooperate with the first opening 2511 to form a channel 253 suitable for allowing the stator shaft 1211 to pass through. The shape and size of the channel 253 are adapted to the shape and size of the stator shaft 1211. The stator shaft 1211 located in the channel 253 can contact the inner wall of the channel 253, thereby improving the coaxiality of the assembly of the stator shaft 1211 with the connector 251.

[0098] The stator shaft 1211 is typically cylindrical. When the connector 251 is installed, the connector 251 can rotate relative to the stator shaft 1211 through the first opening 2511. Even with the abutting force provided by the fastener 252, this rotation cannot be completely avoided. However, the connector 251 also abuts or connects to the light source fixture 221 in the light-emitting assembly 22, but the light source fixture 221 must be prevented from rotating relative to the stator shaft 1211.

[0099] To solve the above problems, in some embodiments of the present application, Figure 12 and Figure 13 As shown, the connecting member 251 may further include an anti-error portion 254, which is located inside the channel 253 formed by the first opening 2511 and the limiting portion 2513, and is connected to at least a portion of the channel 253; an anti-error structure 12112 is provided on the stator shaft 1211, and the anti-error structure 12112 cooperates with the anti-error portion 254 to limit the rotation of the stator shaft 1211 relative to the connecting member 251.

[0100] like Figure 13As shown, the anti-error structure 12112 can be, for example, a flat groove opened on the stator shaft 1211, one end of the flat groove extends to the end of the stator shaft 1211 close to the light-emitting component 22, and the flat groove can be obtained by cutting a part of the external thread 12111 on the stator shaft 1211; the anti-error portion 254 is a protrusion that is adapted to the shape and size of the flat groove.

[0101] When assembling the connector 251 onto the stator shaft 1211, the anti-misalignment portion 254 is aligned with the anti-misalignment structure 12112. The stator shaft 1211 is then inserted into the channel 253, so that the anti-misalignment portion 254 and the anti-misalignment structure 12112 fit together. At this point, due to the shape constraints of the anti-misalignment portion 254 and the anti-misalignment structure 12112, the stator shaft 1211 and the connector 251 cannot rotate relative to each other.

[0102] In some embodiments of the present application, Figure 11 As shown, the connecting member 251 also includes a first flange portion 2514, which is connected to the edge of the connecting plate 2512 and protrudes toward the rotor assembly 122; the first flange portion 2514, the connecting plate 2512 and the limiting portion 2513 are connected by a connecting rib 255.

[0103] The first flange portion 2514 is used to improve the structural strength of the edge portion of the connecting plate 2512 .

[0104] The first flange portion 2514, the connecting plate 2512 and the limiting portion 2513 are connected by at least one connecting rib 255. On the one hand, it can improve the structural strength of the limiting portion 2513, thereby improving the abutment reliability between the connecting member 251 and the stator sleeve 1213; on the other hand, it can provide the structural strength of the connecting plate 2512, thereby improving the connection reliability between the connecting member 251 and the light source fixing member 221, so that the plate body of the connecting plate 2512 is not easy to break.

[0105] Optionally, the connecting plate 2512 , the first flange portion 2514 , the limiting portion 2513 and the connecting rib 255 are integrally formed to further improve the structural strength of the reinforcement.

[0106] In some embodiments of the present application, the connecting plate 2512 further defines a second opening 2515. The connector 251 further includes a second flange portion 2516, which is connected to the edge of the second opening 2515 and protrudes toward the rotor assembly 122. The second flange portion 2516 is connected to at least one of the first flange portion 2514 and the retaining portion 2513 via a connecting rib 255, which is also connected to the connecting plate 2512.

[0107] Second opening 2515 is used to reduce the weight of connector 251, and second flange 2516 is used to increase the structural strength of connecting plate 2512 at the edge of second opening 2515. Second flange 2516 is connected to at least one of first flange 2514 and stopper 2513 via connecting ribs 255, further enhancing the structural strength of connector 251.

[0108] In some embodiments of the present application, the connecting member 251 and the light source fixing member 221 are connected by a fastener 252, and accordingly, a third opening 2517 is provided on the connecting plate 2512 for allowing the fastener to pass through; the connecting member 251 also includes a third flange portion 2518, the third flange portion 2518 is connected to the edge of the third opening 2517, and the third flange portion 2518 is also connected to at least one of the first flange portion 2514, the second flange portion 2516 and the limiting portion 2513 through a connecting rib 255, and the connecting rib 255 is also connected to the connecting plate 2512.

[0109] The third flange portion 2518 is used to improve the structural strength of the connecting plate 2512 at the edge of the third opening 2517. The third flange portion 2518 is connected to at least one of the first flange portion 2514, the second flange portion 2516, and the stop portion 2513 via the connecting rib 255, thereby further improving the structural strength of the connector 251.

[0110] It should be noted that the height dimensions of the first flange portion 2514, the second flange portion 2516, and the third flange portion 2518 are all smaller than the height dimension of the stop portion 2513, so that the first flange portion 2514, the second flange portion 2516, and the third flange portion 2518 are further away from the rotor assembly 122 than the stop portion 2513. The height direction is parallel to the axis of the stator shaft 1211.

[0111] In some embodiments, the number of the second opening 2515, the second flange portion 2516, the third opening 2517, the third flange portion 2518 and the connecting rib 255 are all multiple, and the connecting member 251 is a centrally symmetrical structure, with the center of symmetry located on the axis of the first opening 2511 (when assembled, the axis of the first opening 2511 coincides with the axis of the stator shaft 1211).

[0112] For example, Figure 11As shown, the connecting plate 2512 may be in the shape of a triangular star, with a first opening 2511 located at the exact center of the connecting plate 2512. A second opening 2515 is defined in the middle of each of the three corners of the connecting plate 2512, and a third opening 2517 is defined on a side of each second opening 2515 away from the first opening 2511. The third opening 2517 is not connected to the second opening 2515, and the first opening 2511, second opening 2515, and third opening 2517 all have the same opening direction. A stopper 2513 is connected to the edge of the first opening 2511. A first flange 2514 is connected to the outer edge of the connecting plate 2512. A second flange 2516 is connected to the edge of each second opening 2515, and a third flange 2518 is connected to the edge of each third opening 2517. The connecting plate 2512 is further provided with a plurality of connecting ribs 255 distributed circumferentially along the limiting portion 2513. At least one of the connecting ribs 255 extends radially along the first opening 2511 and sequentially connects the limiting portion 2513, the second flange portion 2516, the third flange portion 2518, and the first flange portion 2514. At least one of the connecting ribs 255 extends radially along the first opening 2511 and connects the limiting portion 2513 and the first flange portion 2514. Among the connecting ribs 255 directly connected to the limiting portion 2513, the angles between any two connecting ribs 255 are equal.

[0113] To facilitate the assembly of the connecting member and the light source fixing member, in some embodiments, as Figure 13 As shown, a first positioning structure 2519 is further provided on the connecting plate 2512, and a second positioning structure 2212 is provided on the light source fixing member 221. The first positioning structure 2519 and the second positioning structure 2212 cooperate to limit the relative position of the connecting plate 2512 and the fixing member.

[0114] Optionally, the first positioning structure 2519 and the second positioning structure 2212 are respectively one of a protrusion and the other of a groove, wherein the groove can be a through groove or a non-through groove.

[0115] by Figure 14 For example, the first positioning structure 2519 is shown as a protrusion, and the second positioning structure 2212 is shown as a through-slot. The protrusion protrudes from the connecting plate 2512 in a direction away from the rotor assembly 122 and is adapted to engage with a corresponding through-slot on the light source fixture 221. The protrusion is located within one of the second openings 2515 and is connected to the connecting plate 2512 and / or the second flange portion 2516. The through-slot is opened on the light source fixture 221 at a position corresponding to the position of the protrusion.

[0116] like Figure 15As shown, in the second possible case, the rotating motor 12 is an inner rotor motor, the hollow shaft 121 is a rotor shaft 1212, and the rotor shaft 1212 is connected to the wind wheel 11. The inner rotor motor includes a stator assembly 123, which surrounds the outer side of the rotor shaft 1212 and has a gap between the stator assembly 123 and the wind wheel 11.

[0117] After the inner rotor motor is started, the hollow rotor shaft 1212 rotates, and the wind wheel 11 rotates synchronously driven by the rotor shaft 1212 to generate airflow, and the stator assembly 123 is fixed.

[0118] In the second case, the fan mechanism 1 includes a fan housing 13, the wind wheel 11 and the rotating motor 12 are located inside the fan housing 13 and spaced apart from the fan housing 13, and the light emitting component 22 is connected to the fan housing 13. The suspension mechanism 3 is connected to the fan housing 13, and the control component 21 is installed inside the suspension mechanism 3. Figure 16 As shown, the lighting mechanism 2 further includes a limiting member 24 , which is connected to the suspension mechanism 3 and is used to limit the position of the conductive member 23 in the rotor shaft 1212 .

[0119] Conductive member 23 is typically a wire. It's easy to understand that when hollow shaft 121 is a rotor shaft 1212, the high-speed rotation of rotor shaft 1212 during operation can cause the wire passing through it to become entangled or worn, potentially leading to safety accidents. To address this issue, the present embodiment includes a stopper 24. This stopper 24 limits the position of conductive member 23 within rotor shaft 1212, preventing it from rotating with rotor shaft 1212 and preventing friction with rotor shaft 1212 that could cause wear, thereby improving safety.

[0120] In the embodiment of the present application, the limiting member 24 can separate the conductive member 23 from the rotor shaft 1212 , thereby preventing the rotor shaft 1212 from affecting the conductive member 23 .

[0121] In some embodiments, as Figure 17 As shown, the limiting member 24 includes a sleeve 241, which is connected to the suspension mechanism 3, and the interior of the sleeve 241 is communicated with the interior of the suspension mechanism 3; the sleeve 241 passes through the rotor shaft 1212, and there is a gap between the sleeve 241 and the inner wall of the rotor shaft 1212, and the conductive member 23 passes through the interior of the sleeve 241.

[0122] The sleeve 241 is made of a rigid material, and compared to a flexible wire, the position of the sleeve 241 is easier to control and constrain. Figure 17As shown, sleeve 241 is fixed to suspension mechanism 3 and located inside rotor shaft 1212. Sleeve 241 and the inner wall of rotor shaft 1212 maintain a certain distance and do not contact each other. Therefore, sleeve 241 remains stationary regardless of whether rotor shaft 1212 rotates at high speed. Passing the wires through sleeve 241 isolates them from rotor shaft 1212, thereby preventing safety accidents caused by wire entanglement and wear.

[0123] In other embodiments, Figure 18 As shown, the limit member 24 may also include a connecting rod 242, which is connected to the suspension mechanism 3 and passes through the rotor shaft 1212, with a gap between the connecting rod 242 and the inner wall of the rotor shaft 1212; a portion of the conductive member 23 extends from the interior of the suspension mechanism 3 and is fixed on the outer wall of the connecting rod 242, with a gap between the conductive member 23 and the inner wall of the rotor shaft 1212.

[0124] The connecting rod 242 is made of a rigid material. Compared with a flexible wire, the position and extension direction of the connecting rod 242 are more controllable. Figure 18 As shown, connecting rod 242 is fixed to suspension mechanism 3 and located inside rotor shaft 1212. Connecting rod 242 does not contact rotor shaft 1212, so regardless of whether rotor shaft 1212 rotates at high speed, connecting rod 242 remains stationary. An opening can be provided at the bottom of suspension mechanism 3, through which conductive member 23 passes and is wrapped around or secured to connecting rod 242. A gap exists between conductive member 23 secured to connecting rod 242 and the inner wall of rotor shaft 1212, thereby preventing safety hazards caused by wire entanglement and wear.

[0125] Alternatively, as Figure 18 As shown, a plurality of wire clips 243 are provided on the connecting rod 242 , and the conductive member 23 is fixed on the connecting rod 242 through the wire clips 243 .

[0126] To sum up, in the bladeless fan lamp provided in the embodiment of the present application, since the rotating motor 12 has a hollow stator shaft 1211 or a hollow rotor shaft 1212, the conductive part 23 used to connect the control component 21 and the light-emitting component 22 of the lighting mechanism 2 can pass through the inside of the hollow shaft 121, thereby avoiding long-distance winding, making the wiring more simple and improving safety, while also saving the material cost of the conductive part 23, thereby reducing the cost of the bladeless fan lamp.

[0127] In some embodiments of the present application, Figure 19As shown, the fan housing 13 includes an outer shell, a first air duct component 14 and a second air duct component 15; the first air duct component 14 and the second air duct component 15 are located inside the outer shell and are arranged around the air outlet of the wind wheel 11, wherein the first air duct component 14 is adjacent to the top of the wind wheel 11, and the second air duct component 15 is adjacent to the bottom of the wind wheel 11, and a duct space 16 surrounding the air outlet is formed between the first air duct component 14 and the second air duct component 15; the first air duct component 14 and the second air duct component 15 are close to each other at one end away from the wind wheel 11 and there is a gap 17 between the two, and the gap 17 is used to discharge the airflow blown out by the wind wheel 11.

[0128] In the embodiment of the present application, the top of the wind wheel 11 refers to the upper part, that is, the part closer to the suspension mechanism 3, and the bottom refers to the lower part, that is, the part closer to the light-emitting component 22.

[0129] The fan mechanism 1 provided in the embodiment of the present application is an air outlet mechanism with hidden blades 116. The wind wheel 11 is located inside the fan housing 13. Accordingly, the air duct space 16 is also formed inside the fan housing 13. Figure 19 As shown, the top of the fan housing 13 is an air inlet grille 131, through which the air inlet of the fan wheel 11 communicates with the outside world. The air duct space 16 is formed by the cooperation of the first air duct component 14 and the second air duct component 15. It is located between the air outlet of the fan wheel 11 and the inner wall of the fan housing 13 and has an annular shape. Through the combination of the fan wheel 11, the first air duct component 14 and the second air duct component 15, air is drawn in from the top of the fan mechanism 1. The air is then blown by the fan wheel 11 to the inner wall of the first air duct component 14 and then out through the annular air duct outlet, forming an annular shape of wind that is blown to the ground, making the air flow softer.

[0130] See also Figure 19 The first duct member 14 and the second duct member 15 define a duct space 16 radially relative to the rotor 11. Since the first duct member 14 and the second duct member 15 become closer to each other as they move radially away from the rotor 11, the cross-sectional area of ​​the resulting duct space 16 decreases as they move radially away from the rotor 11. This helps concentrate the airflow from the rotor 11, improving the efficiency and distance of the airflow at the duct outlet. The duct outlet is defined by the ends of the first duct member 14 and the second duct member 15 that are further away from the rotor 11. The outlet points downward, directing the airflow to a user located below the bladeless fan lamp.

[0131] In the embodiments of this application, Figure 20As shown, the first air duct component 14 and the second air duct component 15 also surround the light-emitting component 22, wherein the edge portion of the light source fixing part 221 is matched with the end of the second air duct component 15 adjacent to the wind wheel 11 to further improve the connection reliability and prevent it from falling due to vibration; at the same time, since the second air duct component 15 is also provided on the radial outer side of the lamp panel, it can also prevent light overflow.

[0132] In the embodiments of this application, Figure 20 As shown, the light-emitting assembly 22 may further include a lampshade 223, which is located on a side of the light-emitting element 222 away from the light source fixture 221, and provides a distance between the light-emitting elements 222. The lampshade 223 is also matingly connected to the end of the second air duct member 15 away from the wind wheel 11. The lampshade 223 not only prevents the human eye from looking directly at the light-emitting element 222, thus providing eye protection, but also prevents dust from entering the interior of the lighting mechanism 2 and causing malfunction of the light-emitting element 222.

[0133] In some embodiments, the wind rotor 11 includes a hub portion 111, which is located opposite the air inlet of the wind rotor 11 and is used to mount and secure the rotating motor 12. The hub portion 111 has an axial hole 113, through which a portion of the rotating motor 12 passes and is located within the wind rotor 11. The rotating motor 12 has a flange 124 connected to the rotor and arranged along the circumference of the rotor. At least a portion of the flange 124 is connected to or abuts against the side of the hub portion 111 facing the light-emitting assembly 22. Exemplarily, the flange 124 and the hub portion 111 are connected together by screws.

[0134] In some embodiments, the hub portion 111 of the wind wheel 11 has a plurality of concentrically arranged annular reinforcement ribs 114 on the side facing the light-emitting component 22. The annular reinforcement ribs 114 are arranged around the shaft hole 113, and two adjacent annular reinforcement ribs 114 are connected by reinforcement ribs 115; the flange 124 of the rotating motor 12 is connected to or against at least one annular reinforcement rib 114.

[0135] like Figure 21 As shown, the hub portion 111 is provided with a plurality of annular reinforcing ribs 114 and a plurality of reinforcing ribs 115. The plurality of annular reinforcing ribs 114 are arranged concentrically with the shaft hole 113, thereby strengthening the hub portion 111. Optionally, the heights of the plurality of annular reinforcing ribs 114 vary. The annular reinforcing ribs 114 closer to the axis of the hub portion 111 have smaller diameters and lower heights; the annular reinforcing ribs 114 further from the axis of the hub portion 111 have larger diameters and higher heights. The height of the outermost annular reinforcing ribs 114 is less than the height of the hub portion 111 protruding into the interior of the wind rotor 11. Adjacent annular reinforcing ribs 114 are connected by at least one reinforcing rib 115 to further increase the strength of the hub portion 111.

[0136] In some embodiments, the base plate of the wind wheel 11 further includes a connecting portion 112 , which is connected to the outer edge of the hub portion 111 ; the connecting portion 112 and the outermost annular reinforcement rib 114 are connected via a reinforcement rib 115 .

[0137] For example, Figure 21 In the bottom plate shown, there are three annular reinforcing ribs 114 on the hub portion 111 from the inside to the outside, among which the first annular reinforcing rib 114 and the second annular reinforcing rib 114 are connected by six reinforcing ribs 115, and the six reinforcing ribs 115 are evenly arranged along the circumference of the annular reinforcing rib 114; the second annular reinforcing rib 114 and the third annular reinforcing rib 114 are also connected by six reinforcing ribs 115, and these six reinforcing ribs 115 correspond to the positions of the six reinforcing ribs 115 on the inner side; the third annular reinforcing rib 114 is connected to the connecting portion 112 by six reinforcing ribs 115, and these six reinforcing ribs 115 correspond to the positions of the twelve reinforcing ribs 115 on the inner side.

[0138] When assembling the rotating motor 12, the flange 124 of the rotating motor 12 abuts against at least one annular reinforcement rib 114 and the reinforcement rib 115, thereby ensuring that the hub portion 111 has good structural strength and can be reliably connected. For example, the rotating motor 12 is fixed to the hub portion 111 by bolt connection, such as Figure 21 As shown, a through hole is formed on the second annular reinforcement rib 114 at the intersection with the reinforcement rib 115, and a through hole is also formed at a corresponding position on the flange 124. Bolts and nuts pass through these two through holes to mount the rotating motor 12 on the wind rotor 11. Optionally, an elastic medium is sleeved on the bolt. When tightened, the elastic medium is clamped between the head of the bolt and the flange 124, and is used to increase the tightness of the connection between the flange 124 and the wind rotor 11.

[0139] In other embodiments of the present application, the base plate of the wind wheel 11 can also be connected to the flange 124 of the rotating motor 12 by an in-mold injection molding process. In practice, the connected rotor and flange 124 can be placed in the injection mold of the wind wheel 11, and then the injection molding material is added to the mold so that after injection molding, the base plate of the wind wheel 11 is wrapped around the outside of the flange 124 to achieve a tight connection between the wind wheel 11 and the flange 124; thereafter, the other components of the rotating motor 12 are mounted on the rotor. Optionally, the flange 124 is provided with at least one protrusion on the side facing the light-emitting component 22 and / or the side facing away from the light-emitting component 22, and the protrusion is used to strengthen the contact area between the flange 124 and the hub portion 111 of the wind wheel 11, thereby increasing the injection molding firmness between the hub portion 111 of the wind wheel 11 and the flange 124, and improving the use strength and service life of the injection molded product.
