[0062] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work 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 present application embodiment 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, 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 and the wiring is simpler, 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 solution and advantages of the present application clearer, the various structures of the bladeless fan lamp provided in the embodiment of the present application are further introduced and illustrated 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 usually installed on the top of the fan mechanism 1, and is used to suspend the bladeless fan light on a mounting carrier, which can be, for example, a ceiling. The fan mechanism 1 and the lighting mechanism 2 are used to provide a blowing function and a lighting function, respectively, wherein the lighting mechanism 2 can be installed at the bottom of the fan mechanism 1. In the embodiment of the present application, the fan mechanism 1 and the lighting mechanism 2 are independent of each other in function, and the user can control the fan mechanism 1 and the lighting mechanism 2 to perform corresponding functions separately.

[0069] In the bladeless fan lamp provided in this embodiment, the fan mechanism 1 includes a fan housing 13, and a wind wheel 11 and a rotating motor 12 located in the fan housing 13. The fan mechanism 1 realizes the blowing function through the wind wheel 11. Since the blades 116 of the wind wheel 11 are hidden in the whole machine housing, the danger caused by accidental touching of the blades 116 when they are exposed to the outside is avoided, thereby improving safety and protection.

[0070] The wind wheel 11 rotates to deliver air under the drive of the rotating motor 12, and the rotating motor 12 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 be electrically connected to the control component 21 and the light-emitting component 22 of the lighting mechanism 2 in a relatively simple wiring manner, and because the winding distance of the conductive member 23 is short, materials are saved and costs are reduced.

[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 is fixed, the rotor assembly 122 rotates around the axis of the stator shaft 1211, and the wind wheel 11 rotates synchronously driven by the rotor assembly 122 to generate airflow. In some embodiments, the two 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 the bladeless fan lamp, the power leads of the outer rotor motor and the lighting mechanism 2 are led out from the suspension mechanism 3 so as to be connected to the external circuit buried in the ceiling for power. The control component 21 of the lighting mechanism 2 is installed inside the suspension mechanism 3 and is electrically connected to the light-emitting component 22 through the conductive member 23 to control the light-emitting component 22 to emit light.

[0076] See also Figure 6 In some embodiments, the end of the stator shaft 1211 close to the suspension mechanism 3 has an external thread 12111, 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, wherein 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 away from the wind wheel 11.

[0078] The light source fixing member 221 may be, for example, a lamp panel, which is not in contact with the wind wheel 11 or the rotor assembly 122, so that when the rotating motor 12 is running, the lamp panel remains stationary. A mounting position for the light emitting element 222 is provided on the side of the lamp panel away from the wind wheel 11. The light emitting element 222 is installed in a corresponding mounting position on the lamp panel, and the light emitting element 222 may be, for example, an LED lamp board for providing illumination light, and the conductive member 23 is suitable for being connected between the control assembly 21 and the LED lamp board.

[0079] Alternatively, if Figure 7 As shown, there are multiple light-emitting elements 222, and the multiple light-emitting elements 222 are symmetrically distributed on the light source fixing member 221 to ensure uniform light emission. The symmetry of the multiple light-emitting elements 222 on the light source fixing member 221 can be axial symmetry, with the axis of symmetry passing through the center point of the light source fixing member 221; or the symmetry can also be central symmetry about the center point of the light source fixing member 221. Optionally, multiple LED light panels can be connected in series with connecting wires, or they can be connected in parallel.

[0080] The light source fixing member 221 is directly or indirectly connected to the stator shaft 1211. In some embodiments of the present application, 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. The fixing assembly 25 is provided with a first opening 2511, and the stator shaft 1211 passes through the first opening 2511, or the conductive member 23 passing through the inside of the stator shaft 1211 passes through the first opening 2511.

[0081] The fixing assembly 25 is connected to the light source fixing member 221 and the stator shaft 1211 at the same time, so that the light source fixing member 221 is assembled on the stator shaft 1211. The fixing assembly 25 is not in contact with the rotor assembly 122 and the wind wheel 11, so that 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 method 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 bolt connection, threaded connection, clamping, riveting, welding, and interference connection.

[0082] In some embodiments of the present 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, and the connecting member 251 is sleeved on the stator shaft 1211 through the first opening 2511 and connected to the light source fixing member 221. The fastener 252 is matched and connected 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; or, the connecting member 251, the light source fixing member 221 and the fastener 252 are sequentially arranged in a direction away from the rotor assembly 122, and the fastener 252 abuts against the light source fixing member 221.

[0083] In a possible case, 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 the fastener 252. Exemplarily, 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, so as to fasten 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 case, 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. Exemplarily, the connecting member 251 is sleeved on the stator shaft 1211 through the first opening 2511; the light source fixing member 221 is sleeved on 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. In addition, the fastener 252 cooperates with the stator shaft 1211, so that the connecting member 251 and the light source fixing member 221 are fastened and connected 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 among the more than one connecting members 251, there are two 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 two opposite sides of the light source fixing member 221 and clamps the light source fixing member 221. Fig. 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 all fastened to the stator shaft 1211.

[0087] The light source fixing member 221 is also connected to two adjacent connecting members 251. For example, Fig. 9 As shown, a through hole is provided on the light source fixing member 221, and a through hole is also provided on the two connecting members 251, and the through hole on the light source fixing member 221 corresponds to the through hole on the two connecting members 251, and the fastening bolt passes through the three through holes at the same time, thereby connecting the light source fixing member 221 and the two connecting members 251 together. By providing a plurality of connecting members 251 to clamp 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: Fig.10 As shown, the rotating motor 12 further includes a stator sleeve 1213, which is connected to the outside of the stator shaft 1211, and the stator shaft 1211 passes 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 close to the light source fixing member 221; the fastener 252 is a nut, which is threadedly matched with the stator shaft 1211, and at least one of the connecting member 251 and the light source fixing member 221 is fastened 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 Fig.10Taking the structure shown as an example, it should be noted that, in this example, the connecting piece 251 is fastened between the stator sleeve 1213 and the nut in a clamping manner. When the connecting piece 251 is connected, the end of the connecting piece 251 away from the nut must be against the stator sleeve 1213, and the other end is against the nut.

[0091] Fig.11 251 is shown. Fig.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 a 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. Fig.11 As shown, the limiting portion 2513 abuts against the stator sleeve 1213, so that the parts of the connecting member 251 except the limiting portion 2513 are 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 the present application, Figure 8 and Fig.11 As shown, the connecting plate 2512 is connected to the light source fixing component 221. In the axial direction of the stator shaft 1211, the distance between the light source fixing component 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 component 221 and the rotor assembly 122 are always non-contact, thereby avoiding mutual influence between the light source fixing component 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, if Fig.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 face of the limiting portion 2513 away from the connecting plate 2512 is an annular end face, which is suitable for abutting against the annular end face of the stator sleeve 1213 and has good stability; and because the stator shaft 1211 passes through the inner side of the annular end face, it can play a certain limiting role, so the connector 251 is not easy to be skewed 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 position 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 Fig.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, and the stator shaft 1211 located in the channel 253 can contact the inner wall of the channel 253, thereby improving the assembly coaxiality of the stator shaft 1211 of the connector 251.

[0098] The stator shaft 1211 is generally cylindrical, and when the connecting member 251 is installed, the connecting member 251 can rotate relative to the stator shaft 1211 through the first opening 2511. Even with the abutment force provided by the fastener 252, this rotation cannot be completely avoided. However, the connecting member 251 is also abutted or connected to the light source fixing member 221 in the light emitting assembly 22, but the light source fixing member 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, Fig.12 and Fig.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 Fig.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 the connector 251 is assembled on the stator shaft 1211, the anti-mistake portion 254 can be aligned with the position of the anti-mistake structure 12112, and then the stator shaft 1211 is inserted into the channel 253, so that the anti-mistake portion 254 and the anti-mistake structure 12112 are matched with each other. At this time, due to the shape restrictions of the anti-mistake portion 254 and the anti-mistake structure 12112, the stator shaft 1211 and the connector 251 cannot rotate relative to each other.

[0102] In some embodiments of the present application, Fig.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 via 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, which can, on the one hand, 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 structural strength for 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 is further provided with a second opening 2515; the connecting member 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 stop portion 2513 via a connecting rib 255, and the connecting rib 255 is also connected to the connecting plate 2512.

[0107] The second opening 2515 is used to reduce the deadweight of the connecting member 251, and the second flange portion 2516 is used to improve the structural strength of the connecting plate 2512 at the edge of the second opening 2515. The second flange portion 2516 is connected to at least one of the first flange portion 2514 and the limiting portion 2513 through the connecting rib 255, which can further provide the structural strength of the connecting member 251.

[0108] In some embodiments of the present application, the connecting member 251 and the light source fixing member 221 are connected via 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 via 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 limiting portion 2513 through the connecting rib 255, which can further provide the structural strength of the connecting member 251.

[0110] It should be noted that the dimensions of the first flange portion 2514, the second flange portion 2516 and the third flange portion 2518 in the height direction are all smaller than the dimension of the stop portion 2513 in the height direction, 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, and the center of symmetry is 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, Fig.11As shown, the connecting plate 2512 may be in the shape of a triangular star, and the first opening 2511 is located at the exact center of the connecting plate 2512; a second opening 2515 is provided in the middle of each of the three corners of the connecting plate 2512, and a third opening 2517 is provided 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 opening directions of the first opening 2511, the second opening 2515 and the third opening 2517 are all the same. The limiting portion 2513 is connected to the edge of the first opening 2511, the outer edge of the connecting plate 2512 is connected to the first flange portion 2514, the edge of each second opening 2515 is connected to the second flange portion 2516, and the edge of each third opening 2517 is connected to the third flange portion 2518. The connecting plate 2512 is also provided with a plurality of connecting ribs 255 distributed in the circumferential direction of the limiting portion 2513. Among the plurality of connecting ribs 255, at least one connecting rib 255 extends in the radial direction of 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. Among the plurality of 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 Fig.13 As shown, a first positioning structure 2519 is also 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 with each other 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 may be a through groove or a non-through groove.

[0115] by Fig.14 The first positioning structure 2519 shown is a protrusion, and the second positioning structure 2212 is a through slot. For example, the protrusion protrudes on the connecting plate 2512 in a direction away from the rotor assembly 122, and is suitable for being inserted into the corresponding through slot on the light source fixing member 221. The protrusion is located in one of the second openings 2515 and is connected to the connecting plate 2512 and / or the second flange portion 2516. The opening position of the through slot on the light source fixing member 221 corresponds to the position of the protrusion.

[0116] like Fig.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 with 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 are 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. Fig.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] The conductive member 23 is usually a wire. It is easy to understand that when the hollow shaft 121 is a rotor shaft 1212, since the rotor shaft 1212 rotates at high speed during operation, the wire passing therethrough may be entangled or worn, causing a safety accident. To solve this problem, a stopper 24 is additionally provided in the embodiment of the present application. The stopper 24 can limit the position of the conductive member 23 located inside the rotor shaft 1212, so that it cannot rotate with the rotor shaft 1212, and it will not cause friction with the rotor shaft 1212 and 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, Fig.17 As shown, the limit member 24 includes a sleeve 241, which is connected to the suspension mechanism 3, and the interior of the sleeve 241 is connected to 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 restrict. Fig.17As shown, the sleeve 241 is fixed on the suspension mechanism 3 and is located inside the rotor shaft 1212, wherein the sleeve 241 and the inner wall of the rotor shaft 1212 maintain a certain distance and do not contact each other, so that the sleeve 241 remains stationary regardless of whether the rotor shaft 1212 rotates at a high speed. The wire is passed through the inside of the sleeve 241 to isolate the wire from the rotor shaft 1212, thereby avoiding safety accidents caused by winding and wear of the wire.

[0123] In other embodiments, Fig.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, and there is a gap between the connecting rod 242 and the inner wall of the rotor shaft 1212; a part 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, and there is 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. Fig.18 As shown, the connecting rod 242 is fixed on the suspension mechanism 3 and is located inside the rotor shaft 1212, wherein the connecting rod 242 does not contact the rotor shaft 1212, so that the connecting rod 242 remains stationary regardless of whether the rotor shaft 1212 rotates at a high speed. An opening can be provided at the bottom of the suspension mechanism 3, and the conductive member 23 passes through the opening and is wound around or fixed on the connecting rod 242. Since there is a gap between the conductive member 23 fixed on the connecting rod 242 and the inner wall of the rotor shaft 1212, safety accidents caused by winding and wear of the wire are avoided.

[0125] Alternatively, if Fig.18 As shown, a plurality of wire clamps 243 are provided on the connecting rod 242 , and the conductive member 23 is fixed on the connecting rod 242 via the wire clamps 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 concise 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, Fig.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, the second air duct component 15 is adjacent to the bottom of the wind wheel 11, and an air 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 respectively, 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 portion located above, that is, the portion closer to the suspension mechanism 3, and the bottom refers to the portion located below, that is, the portion closer to the light-emitting component 22.

[0129] The fan mechanism 1 provided in the embodiment of the present application is a wind outlet mechanism with hidden blades 116, and 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. Fig.19 As shown, the top of the fan housing 13 is an air inlet grille 131, through which the air inlet of the wind wheel 11 is connected to the outside; the air duct space 16 is formed by the cooperation of the first air duct component 14 and the second air duct component 15, and is located between the air outlet of the wind wheel 11 and the inner wall of the fan housing 13, and is annular. Through the combination of the wind wheel 11 and the first air duct component 14 and the second air duct component 15, the air flow is sucked in from the top of the fan mechanism 1, and then the wind is blown by the wind wheel 11 to the inner wall of the first air duct component 14 and then blown out through the annular air duct outlet, forming annular wind and blowing to the ground, making the wind output softer.

[0130] See also Fig.19 The first air duct component 14 and the second air duct component 15 form an air duct space 16 along the radial direction of the wind wheel 11. Since the first air duct component 14 and the second air duct component 15 are closer to each other as they are farther away from the wind wheel 11, the formed air duct space 16 has a smaller cross-sectional area as it is farther away from the wind wheel 11 in the radial direction, thereby helping to concentrate the airflow blown out by the wind wheel 11 and improve the air outlet efficiency and air supply distance of the air duct outlet. The air duct outlet is surrounded by the end of the first air duct component 14 away from the wind wheel 11 and the end of the second air duct component 15 away from the wind wheel 11, and the outlet direction points downward so that the airflow blows to the user located below the bladeless fan lamp.

[0131] In the embodiments of the present application, Fig. 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 and connected with one end of the second air duct component 15 adjacent to the wind wheel 11, so as 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 the present application, Fig. 20 As shown, the light emitting assembly 22 may further include a lampshade 223, which is located at a side of the light emitting element 222 away from the light source fixing member 221, and there is a distance between the light emitting elements 222; the lampshade 223 is also matched and connected with an end of the second air duct member 15 away from the wind wheel 11. By providing the lampshade 223, on the one hand, it can prevent the human eye from looking directly at the light emitting element 222, which has the effect of protecting the eyes, and on the other hand, it can prevent dust from entering the interior of the lighting mechanism 2 and causing the light emitting element 222 to malfunction.

[0133] In some embodiments, the wind wheel 11 includes a hub portion 111, which is opposite to the air inlet position of the wind wheel 11 and is used to install and fix the rotating motor 12. The hub portion 111 has an axial hole 113, and a part of the rotating motor 12 passes through the axial hole 113 and is located inside the wind wheel 11. The rotating motor 12 has a flange 124 connected to the rotor and arranged along the circumference of the rotor, and at least a part of the flange 124 is connected to or abuts against a side of the hub portion 111 facing the light-emitting component 22. Exemplarily, the flange 124 is connected to the hub portion 111 by screws.

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

[0135] like Fig.21 As shown, the hub 111 is provided with a plurality of annular reinforcing ribs 114 and a plurality of reinforcing ribs 115, and the plurality of annular reinforcing ribs 114 are arranged concentrically with the shaft hole 113, so as to strengthen the strength of the hub 111. Optionally, the heights of the plurality of annular reinforcing ribs 114 are different from each other, and the annular reinforcing ribs 114 closer to the axis of the hub 111 have smaller diameters and lower heights; the annular reinforcing ribs 114 farther from the axis of the hub 111 have larger diameters and higher heights; the height of the outermost annular reinforcing ribs 114 is less than the protrusion height of the hub 111 toward the inside of the wind wheel 11. Two adjacent annular reinforcing ribs 114 are connected by at least one reinforcing rib 115, so as to further increase the strength of the hub 111.

[0136] In some embodiments, the bottom 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 reinforcing rib 114 are connected via a reinforcing rib 115 .

[0137] For example, Fig.21 In the bottom plate shown, there are three annular reinforcing ribs 114 on the hub portion 111 from the inside to the outside, wherein 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 the positions of these six reinforcing ribs 115 correspond to 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 the positions of these six reinforcing ribs 115 correspond to the twelve reinforcing ribs 115 on the inner side.

[0138] When the rotating motor 12 is assembled, the flange 124 of the rotating motor 12 abuts against at least one of the annular reinforcing ribs 114 and the reinforcing ribs 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 Fig.21 As shown, a through hole is formed at the position where the second annular reinforcing rib 114 intersects with the reinforcing rib 115, and a through hole is also formed at the corresponding position on the flange 124. Bolts and nuts pass through these two through holes to mount the rotating motor 12 on the wind wheel 11. Optionally, an elastic medium is also sleeved on the bolt. In the tightened state, the elastic medium is clamped between the head of the bolt and the flange 124, and the elastic medium is used to increase the connection tightness between the flange 124 and the wind wheel 11.

[0139] In some other embodiments of the present application, the bottom 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.
