DETAILED DESCRIPTION

[0092] 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.

[0093] This embodiment relates to a bladeless fan lamp, as shown in Figures 1 and 2 . The bladeless fan lamp includes a fan mechanism 1, wherein the fan mechanism 1 includes a wind wheel 11 and a motor 12. The wind wheel 11 has an air inlet 111 at the top and an air outlet 112 on the side thereof, and the air outlet 112 is arranged circumferentially around the wind wheel 11. The motor 12 is connected to the wind wheel 11 to drive the wind wheel 11 to rotate.

[0094] By having the air inlet 111 of the wind rotor 11 at the top and the air outlet 112 at the side of the wind rotor 11, the air inlet 111 and the air outlet 112 do not interfere with each other, thereby improving the stability of the air outlet of the wind rotor 11. In addition, the air outlet 112 of the wind rotor 11 is arranged along the circumferential direction of the wind rotor 11, so that the wind rotor 11 can discharge air evenly along its circumferential direction, thereby increasing the air outlet area.

[0095] In related art, the rotating motor 12 used to drive the turbine blades 115 is typically placed on the central axis of the entire unit. The central portion of the rotating motor 12 serves as the armature core, with multiple coil windings surrounding the outer portion of the armature core. The light panel in a fan light is typically located at the bottom of the unit. The wiring for the light panel bypasses the outside of the air duct and is secured to the outer wall of the duct with wire clips to avoid the turbine blades 115. However, this wiring method for the light panel is complex and requires long winding distances, increasing material costs.

[0096] In this regard, an embodiment of the present application provides a bladeless fan lamp, which is generally used in indoor environments. As shown in Figure 3, 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 motor 12, and the wind wheel 11 is driven by the motor 12. Since the motor 12 is used to drive the wind wheel 11 to rotate, the motor 12 can also be called a rotary motor 12. The 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 rotary 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.

[0097] In the bladeless fan lamp provided in the embodiment of the present application, a rotating motor 12 having a hollow shaft 121 is used to drive the wind wheel 11 to rotate. 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 interior of the hollow shaft 121 of the rotating motor 12 and is electrically connected to the light-emitting component 22. Compared to the related art of winding the wire from the outside of the air duct, the solution of this embodiment is to directly pass the wire through the hollow shaft 121 of the motor 12, 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, due to the short winding distance, the wiring is simpler, which can also prevent the conductive members 23 from entangled with each other, thereby improving safety.

[0098] 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.

[0099] (1) Installation method of bladeless fan light

[0100] As shown in FIG1 and FIG3 , 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 .

[0101] 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.

[0102] In the bladeless fan light 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 wind wheel 11 is spaced apart from the fan housing 13. The fan mechanism 1 achieves its blowing function through the wind wheel 11. Because the blades 115 of the wind wheel 11 are hidden within the overall housing, the danger of accidental contact of the exposed blades 115 is avoided, thereby improving safety and security. This fan light in which the blades 115 are invisible to the user can be called a bladeless fan light.

[0103] The wind wheel 11 rotates and delivers air driven by the motor 12, which has a hollow shaft 121. The hollow shaft 121 is adapted to allow the conductive member 23 to pass through, thereby enabling the conductive member 23 to electrically connect the control assembly 21 and the light-emitting assembly 22 of the lighting mechanism 2 in a relatively simple wiring manner. Furthermore, the short winding distance of the conductive member 23 saves material and reduces costs.

[0104] In the embodiment of the present application, the hollow shaft 121 of the motor 12 may be a stator shaft 1221 or a rotor shaft 124. The following describes the relevant structures of the bladeless fan lamp for these two possible situations.

[0105] As shown in FIG2 , in the first possible case, the motor 12 is an outer rotor motor 12 and the hollow shaft 121 is a stator shaft 1221 . The outer rotor motor 12 includes a rotor assembly 123 , which surrounds the outer side of the stator shaft 1221 and is connected to the wind wheel 11 .

[0106] After the outer rotor motor 12 is started, the hollow stator shaft 1221 remains stationary, while the rotor assembly 123 rotates about the axis of the stator shaft 1221. Driven by the rotor assembly 123, the impeller 11 rotates synchronously, generating airflow. In some embodiments, the ends of the hollow stator shaft 1221 extend from opposite sides of the rotor assembly 123 and are connected to the suspension mechanism 3 and the lighting mechanism 2, respectively.

[0107] As shown in Figures 4 and 5, in some embodiments of the present application, the suspension mechanism 3 and the control assembly 21 are located on the same side of the outer rotor motor 12. The suspension mechanism 3 is connected to the stator shaft 1221, and the interior of the suspension mechanism 3 is connected to the interior of the stator shaft 1221, so that the conductive member 23 can pass through the interior of the stator shaft 1221 and extend into the interior of the suspension mechanism 3. In some embodiments, the control assembly 21 is installed inside the suspension mechanism 3, and the control assembly 21 and the light-emitting assembly 22 are respectively located on opposite sides of the motor 12.

[0108] In this bladeless fan lamp, power leads for the outer rotor motor 12 and the lighting mechanism 2 are both led out of 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.

[0109] In some embodiments, as shown in Figures 4 and 5, the suspension mechanism 3 is located above the air inlet 111 on the wind wheel 11, and the radial dimension of the suspension mechanism 3 in the wind wheel 11 may be smaller than the diameter of the air inlet 111. For example, there may be a height gap between the suspension mechanism 3 and the air inlet 111, and the wind wheel 11 may be able to absorb air through the air inlet 111, as well as the suspension mechanism 3 and the air inlet 111. Therefore, setting the radial dimension of the suspension mechanism 3 to be smaller than the diameter of the air inlet 111 can prevent the suspension mechanism 3 from blocking the wind wheel 11 from absorbing air. In some embodiments, the radial dimension of the suspension mechanism 3 can be understood as the maximum dimension of the suspension mechanism 3 in the radial direction of the wind wheel 11.

[0110] In some embodiments, as shown in FIG5 , the bottom of the suspension mechanism 3 can pass through the air inlet 111 and be accommodated in the height space of the wind wheel 11. In this way, the height dimension of the bladeless fan lamp can be reduced.

[0111] The height space of the wind wheel 11 can be understood as the entire space enclosed between the lower edge and the upper edge of the wind wheel 11 in the height direction. The height space can include not only the space inside the wind wheel, but also the space enclosed by the curvature of the outer shell of the wind wheel itself.

[0112] In some embodiments, as shown in Figures 4 and 5 , the wind rotor 11 may include a bottom plate 113, a top plate 114, and blades 115. The bottom plate 113 and top plate 114 are arranged opposite each other in a height direction parallel to the rotation axis of the wind rotor 11. An air inlet 111 is provided on the top plate 114, and the bottom plate 113 is located below the top plate 114, opposing the air inlet 111. The blades 115 are connected between the bottom plate 113 and the top plate 114. For example, as shown in Figures 4 and 5 , the bottom plate 113 may define the lower edge of the wind rotor 11 in the height direction, while the top plate 114 may define the upper edge of the wind rotor 11 in the height direction. Thus, the space formed between the bottom plate 113 and the top plate 114 may serve as part of the height space of the wind rotor 11. Furthermore, as shown in Figure 5 , the bottom plate 113 may partially protrude toward the top plate 114 to form a hub 1131. In this way, the other plates connected to the hub portion 1131 in the bottom plate 113 can limit the lower edge of the wind rotor 11 in the height direction to form a height space. In this case, the side of the raised hub portion 1131 away from the air inlet 111 and the other plates surrounding the hub portion 1131 form a raised space, which is part of the height space of the wind rotor.

[0113] Referring to Figure 6, in some embodiments, the end of the stator shaft 1221 close to the suspension mechanism 3 has an external thread 12211, and the suspension mechanism 3 has an internal thread 312. The stator shaft 1221 and the suspension mechanism 3 are connected by the external thread 12211 and the internal thread 312, and the connection method is simple and reliable.

[0114] In some embodiments, as shown in FIG6 , the suspension mechanism 3 may include a suspension housing 31 having a through hole 311 formed at the bottom thereof, through which the stator shaft 1221 may extend into the interior of the suspension housing 31. An internal thread 312 is provided on the inner wall of the through hole 311 to mate with an external thread 12211 on the outer wall of the stator shaft 1221.

[0115] In some embodiments of the present application, as shown in Figure 7, the light-emitting assembly 22 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 1221, and is spaced apart from the rotor assembly 123, wherein a through opening 2211 is opened in the middle position of the light source fixing member 221, and the stator shaft 1221 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.

[0116] The light source fixture 221 can be, for example, a lamp panel. The lamp panel, wind rotor 11, and rotor assembly 123 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.

[0117] Optionally, as shown in FIG7 , there are multiple light-emitting elements 222, and the multiple light-emitting elements 222 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 the symmetry 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.

[0118] The light source fixing member 221 is directly or indirectly connected to the stator shaft 1221. In some embodiments of the present application, as shown in FIG8 , the lighting mechanism 2 further includes a fixing assembly 25 connected to at least one of the stator shaft 1221 and the light source fixing member 221.

[0119] The fixing assembly 25 is provided with a first opening 25111 , and the stator shaft 1221 passes through the first opening 25111 , or the conductive member 23 passing through the inside of the stator shaft 1221 passes through the first opening 25111 .

[0120] In some embodiments, the fixing assembly 25 is connected to the light source fixing member 221 and the stator shaft 1221, respectively, so that the light source fixing member 221 is assembled to the stator shaft 1221. The fixing assembly 25 does not contact either the rotor assembly 123 or the wind wheel 11, so that when the rotor assembly 123 rotates around the stator shaft 1221, the light source fixing member 221 and the fixing assembly 25 connected to the stator shaft 1221 remain stationary. Exemplarily, the connection between the fixing assembly 25 and the light source fixing member 221 or the stator shaft 1221 includes, but is not limited to, at least one of bolting, threading, clamping, riveting, welding, and interference fit.

[0121] In some embodiments of the present application, referring to FIG8 , the fixing assembly 25 may include at least one connecting member 251 and at least one first fastener 252. Each connecting member 251 has a first opening 25111 as described above, and the connecting member 251 is sleeved on the stator shaft 1221 through the first opening 25111. The first fastener 252 cooperates with the stator shaft 1221 to fix the at least one connecting member 251 on the stator shaft 1221, wherein the first fastener 252 is located on a side of the connecting member 251 away from the rotor assembly 123 and abuts against the connecting member 251; alternatively, the connecting member 251, the light source fixing member 221, and the first fastener 252 are sequentially arranged in a direction away from the rotor assembly 123, and the first fastener 252 abuts against the light source fixing member 221.

[0122] 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 1221 by the first fastener 252. For example, the connecting member 251 is sleeved on the stator shaft 1221 through the first opening 25111, and the first fastener 252 can abut against the connecting member 251 and cooperate with the stator shaft 1221, thereby fastening the connecting member 251 to the stator shaft 1221; the light source fixing member 221 can be connected to the connecting member 251 by screws.

[0123] 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 1221 by the first fastener 252. For example, the connecting member 251 is sleeved onto the stator shaft 1221 through the first opening 25111; the light source fixing member 221 is sleeved onto the stator shaft 1221 through the through opening 2211 and is located on the side of the connecting member 251 away from the rotor assembly 123 (or the wind wheel 11); the first fastener 252 is located on the side of the light source fixing member 221 away from the rotor assembly 123 (or the wind wheel 11) and abuts against the light source fixing member 221. In this case, under the action of the abutting force of the first fastener 252, the light source fixing member 221 and the connecting member 251 also abut against each other. Furthermore, the first fastener 252 cooperates with the stator shaft 1221, thereby fastening the connecting member 251 and the light source fixing member 221 to the stator shaft 1221. In this case, the connecting member 251 and the light source fixing member 221 may not be connected to each other to simplify assembly; alternatively, 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.

[0124] The at least one connecting member 251 may be located between the light source fixing member 221 and the wind wheel 11 ; and / or, the at least one connecting member 251 may be located on a side of the light source fixing member 221 away from the wind wheel 11 .

[0125] In some embodiments of the present application, there may be more than one connecting member 251. As shown in FIG9 , two of the more than one connecting members 251 are adjacent to the light source fixing member 221 and are located on opposite sides of the light source fixing member 221. The light source fixing member 221 is connected to the two connecting members 251 respectively.

[0126] The number of connecting members 251 and first fasteners 252 can be the same, so that each connecting member 251 is fixedly coupled with one first fastener 252. Alternatively, the number of connecting members 251 can be less than the number of first fasteners 252. For example, as shown in FIG9 , the fixing assembly 25 can include two connecting members 251 and one first fastener 252, with the first fastener 252 located on a side of the two connecting members 251 away from the wind rotor 11.

[0127] 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, as shown in FIG9 , there are two connecting members 251, and the light source fixing member 221 and the two connecting members 251 are all sleeved on the stator shaft 1221, with the light source fixing member 221 clamped between the two connecting members 251; the first fastener 252 is located on a side of the light source fixing member 221 and the two connecting members 251 away from the rotor assembly 123, abuts against the adjacent connecting member 251, and cooperates with the stator shaft 1221, thereby fastening the two connecting members 251 and the light source fixing member 221 to the stator shaft 1221.

[0128] The light source fixture 221 is also connected to two adjacent connecting members 251. For example, as shown in FIG9 , a through-hole is provided on the light source fixture 221, and a through-hole is also provided on each of the two connecting members 251. The through-holes on the light source fixture 221 correspond to the through-holes on the two connecting members 251. Fastening bolts simultaneously penetrate these three through-holes, connecting the light source fixture 221 and the two connecting members 251. By providing multiple connecting members 251 to sandwich and connect the light source fixture 221, the connection stability and reliability of the light source fixture 221 can be improved.

[0129] In some embodiments of the present application, the structure of the motor 12 is shown in FIG10 . The motor 12 further includes a stator sleeve 1222, which is connected to the outside of the stator shaft 1221. The stator shaft 1221 passes through and is connected to the stator sleeve 1222. The rotor assembly 123 surrounds the outside of the stator sleeve 1222. The stator shaft 1221 and stator sleeve 1222 are collectively referred to as the inner stator assembly 122. The rotor assembly 123 is sleeved on the outside of the inner stator assembly 122.

[0130] Among them, the stator shaft 1221 extends out of the stator sleeve 1222 and has an external thread 12211 at one end close to the light source fixing member 221; the first fastener 252 is a nut, which is threadedly matched with the stator shaft 1221 to fasten at least one of the connecting member 251 and the light source fixing member 221 between the stator sleeve 1222 and the nut.

[0131] In this embodiment, a portion of the stator shaft 1221 extends out of the stator sleeve 1222, 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 1221, and the nut is also threadedly engaged with the external thread 12211 on the stator shaft 1221 through the internal thread 312 to complete the fastening of at least one of the connecting member 251 and the light source fixing member 221 on the stator shaft 1221.

[0132] Taking the structure shown in Figure 10 as an example, it should be noted that, in this example, the connecting member 251 is fastened between the stator sleeve 1222 and the nut in a clamping manner. When fixing the connecting member 251, the end of the connecting member 251 away from the nut must be against the stator sleeve 1222, and the other end must be against the nut.

[0133] FIG11 illustrates the structure of a connector 251. Referring to FIG11 , in some embodiments of the present application, the connector 251 includes a connecting plate 2511 and a stopper 2512. A first opening 25111 is located on the connecting plate 2511. The stopper 2512 is connected to a side of the connecting plate 2511 near the rotor assembly 123 and abuts against the stator sleeve 1222 to create a gap between the connector 251 and the rotor assembly 123.

[0134] The limiting portion 2512 is used to limit the relative position between the connecting member 251 and the rotor assembly 123. As shown in Figures 10 and 11, the limiting portion 2512 abuts against the stator sleeve 1222, so that the portion of the connecting member 251 other than the limiting portion 2512 is away from the rotor assembly 123. Although the distance between the limiting portion 2512 and the rotor assembly 123 is relatively close, since it abuts against the stator sleeve 1222, it will not contact the rotor assembly 123. As a result, the connecting member 251 as a whole does not contact the rotor assembly 123, avoiding friction and mutual influence between the rotor assembly 123. For example, as shown in Figure 10, the side of the limiting portion 2512 away from the connecting plate 2511 can extend into the stator sleeve 1222. Moreover, the radial dimension of the limiting portion 2512 close to the connecting plate 2511 can be larger than the inner diameter of the stator sleeve 1222 , so that the side of the limiting portion 2512 close to the connecting plate 2511 can be exposed outside the stator sleeve 1222 and abut against the lower end edge of the stator sleeve 1222 .

[0135] In the embodiment of the present application, in combination with what is shown in Figure 8 and Figure 11, the connecting plate 2511 is connected to the light source fixing part 221. In the axial direction of the stator shaft 1221, the distance between the light source fixing part 221 and the rotor assembly 123 is greater than the distance between the limiting portion 2512 and the rotor assembly 123, thereby ensuring that the light source fixing part 221 and the rotor assembly 123 are always non-contact, thereby avoiding mutual influence between the light source fixing part 221 and the rotatable rotor assembly 123.

[0136] In the embodiment of the present application, the limiting portion 2512 can be of any shape and connected to any position on the side of the connecting plate 2511 facing the rotor assembly 123, as long as the distance between the part of the connecting member 251 other than the limiting portion 2512 and the rotor assembly 123 can be increased.

[0137] Alternatively, as shown in FIG11 , the limiting portion 2512 may be disposed around the first opening 25111, with the stator shaft 1221 passing through the limiting portion 2512. In this case, the end surface of the limiting portion 2512 away from the connecting plate 2511 is an annular end surface, which is adapted to abut against the annular end surface of the stator sleeve 1222, thus providing excellent stability. Furthermore, since the stator shaft 1221 passes through the inner side of the annular end surface, it provides a certain limiting effect. Therefore, the connector 251 is less likely to become skewed under the action of the abutting force, thereby improving the reliability of the abutting fit.

[0138] In some embodiments, the connecting plate 2511 has a recessed portion 25112 located in the central area, and the recessed portion 25112 is farther away from the outer rotor motor 12 (or the rotor assembly 123) than other portions of the connecting plate 2511; the first opening 25111 can be opened at the center position of the recessed portion 25112, and when the limiting portion 2512 surrounding the first opening 25111 abuts against the stator sleeve 1222, the forces on various portions of the connecting plate 2511 are relatively balanced.

[0139] In some embodiments, referring to FIG12 , the stopper 2512 can be connected to the edge of the first opening 25111 and cooperate with the first opening 25111 to form a channel 2513 suitable for allowing the stator shaft 1221 to pass through. The shape and size of the channel 2513 are adapted to the shape and size of the stator shaft 1221. The stator shaft 1221 located in the channel 2513 can contact the inner wall of the channel 2513, thereby improving the assembly coaxiality of the stator shaft 1221 of the connector 251.

[0140] The stator shaft 1221 is typically cylindrical. When the connector 251 is installed, the connector 251 can rotate relative to the stator shaft 1221 through the first opening 25111. Even with the abutting force provided by the first 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 1221.

[0141] To solve the above problems, in some embodiments of the present application, as shown in Figures 12 and 13, the connecting member 251 may further include an anti-error portion 2514, which is located inside the channel 2513 formed by the first opening 25111 and the limiting portion 2512, and is connected to at least a portion of the channel 2513; an anti-error structure 12212 is provided on the stator shaft 1221, and the anti-error structure 12212 cooperates with the anti-error portion 2514 to limit the rotation of the stator shaft 1221 relative to the connecting member 251.

[0142] As shown in Figure 13, the anti-error structure 12212 can be, for example, a flat groove opened on the stator shaft 1221, one end of the flat groove extends to the end of the stator shaft 1221 close to the light-emitting component 22, and the flat groove can be obtained by cutting a part of the external thread 12211 on the stator shaft 1221; the anti-error portion 2514 is a protrusion that is adapted to the shape and size of the flat groove.

[0143] When assembling the connector 251 onto the stator shaft 1221, the anti-misalignment portion 2514 is aligned with the anti-misalignment structure 12212. The stator shaft 1221 is then inserted into the channel 2513, allowing the anti-misalignment portion 2514 and the anti-misalignment structure 12212 to engage with each other. At this point, due to the shape constraints of the anti-misalignment portion 2514 and the anti-misalignment structure 12212, the stator shaft 1221 and the connector 251 cannot rotate relative to each other.

[0144] In some embodiments of the present application, as shown in Figure 11, the connecting member 251 also includes a first flange 1232, which is connected to the edge of the connecting plate 2511 and protrudes toward the rotor assembly 123; the first flange 1232, the connecting plate 2511 and the limiting portion 2512 are connected by a connecting rib 2517.

[0145] The first flange 1232 is used to improve the structural strength of the edge portion of the connecting plate 2511 .

[0146] The first flange 1232, the connecting plate 2511 and the limiting portion 2512 are connected by at least one connecting rib 2517. On the one hand, it can improve the structural strength of the limiting portion 2512, thereby improving the abutment reliability between the connecting member 251 and the stator sleeve 1222; on the other hand, it can provide the structural strength of the connecting plate 2511, 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 2511 is not easy to break.

[0147] Optionally, the connecting plate 2511 , the first flange 1232 , the limiting portion 2512 and the connecting rib 2517 are integrally formed to further improve the structural strength of the connecting member 251 .

[0148] In some embodiments of the present application, the connecting plate 2511 further defines a second opening 25113. The connector 251 further includes a second flange 1232, which is connected to the edge of the second opening 25113 and protrudes toward the rotor assembly 123. The second flange 1232 is connected to at least one of the first flange 1232 and the retaining portion 2512 via a connecting rib 2517. The connecting rib 2517 is also connected to the connecting plate 2511.

[0149] Second opening 25113 is used to reduce the weight of connector 251, and second flange 1232 is used to increase the structural strength of connecting plate 2511 at the edge of second opening 25113. Second flange 1232 is connected to at least one of first flange 1232 and retaining portion 2512 via connecting rib 2517, further enhancing the structural strength of connector 251.

[0150] In some embodiments of the present application, the connecting member 251 and the light source fixing member 221 are connected by a fastener, and accordingly, a third opening 25114 is provided on the connecting plate 2511 for allowing the fastener to pass through; the connecting member 251 also includes a third flange 1232, the third flange 1232 is connected to the edge of the third opening 25114, and the third flange 1232 is also connected to at least one of the first flange 1232, the second flange 1232 and the limiting portion 2512 through a connecting rib 2517, and the connecting rib 2517 is also connected to the connecting plate 2511.

[0151] Third flange 1232 is used to improve the structural strength of connecting plate 2511 at the edge of third opening 25114. Third flange 1232 is connected to at least one of first flange 1232, second flange 1232, and stopper 2512 via connecting ribs 2517, further enhancing the structural strength of connector 251.

[0152] It should be noted that the height dimensions of the first flange 1232, the second flange 1232, and the third flange 1232 are all smaller than the height dimension of the stopper 2512, so that the first flange 1232, the second flange 1232, and the third flange 1232 are further away from the rotor assembly 123 than the stopper 2512. The height direction is parallel to the axis of the stator shaft 1221.

[0153] In some embodiments, the number of the second opening 25113, the second flange 1232, the third opening 25114, the third flange 1232 and the connecting rib 2517 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 25111 (when assembled, the axis of the first opening 25111 coincides with the axis of the stator shaft 1221).

[0154] For example, as shown in FIG11 , the connecting plate 2511 may be in the shape of a triangular star, with a first opening 25111 located at the exact center of the connecting plate 2511. A second opening 25113 is formed in the middle of each of the three corners of the connecting plate 2511, and a third opening 25114 is formed on a side of each second opening 25113 away from the first opening 25111. The third opening 25114 is not connected to the second opening 25113, and the opening directions of the first opening 25111, the second opening 25113, and the third opening 25114 are all the same. The limiting portion 2512 is connected to the edge of the first opening 25111. The outer edge of the connecting plate 2511 is connected to the first flange 1232. The edge of each second opening 25113 is connected to the second flange 1232, and the edge of each third opening 25114 is connected to the third flange 1232. The connecting plate 2511 is further provided with a plurality of connecting ribs 2517 distributed circumferentially along the limiting portion 2512. At least one of the connecting ribs 2517 extends radially along the first opening 25111 and sequentially connects the limiting portion 2512, the second flange 1232, the third flange 1232, and the first flange 1232. At least one of the connecting ribs 2517 extends radially along the first opening 25111 and connects the limiting portion 2512 and the first flange 1232. Among the connecting ribs 2517 directly connected to the limiting portion 2512, the angles between any two connecting ribs 2517 are equal.

[0155] To facilitate the assembly of the connecting member 251 and the light source fixing member 221, in some embodiments, as shown in Figure 13, a first positioning structure 2519 is also provided on the connecting plate 2511, 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 2511 and the fixing member.

[0156] 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.

[0157] Taking the example of the first positioning structure 2519 in FIG14 as a protrusion and the second positioning structure 2212 as a through-slot, the protrusion protrudes from the connecting plate 2511 in a direction away from the rotor assembly 123 and is adapted to engage with the corresponding through-slot on the light source fixture 221. The protrusion is located within one of the second openings 25113 and is connected to the connecting plate 2511 and / or the second flange 1232. The through-slot is located on the light source fixture 221 at a position corresponding to the position of the protrusion.

[0158] As shown in FIG15 , in the second possible embodiment, motor 12 is an inner rotor motor 12, hollow shaft 121 is a rotor shaft 124, and rotor shaft 124 is connected to wind rotor 11. Inner rotor motor 12 includes an outer stator assembly 125, which surrounds the outer side of rotor shaft 124 and has a gap between it and wind rotor 11.

[0159] After the inner rotor motor 12 is started, the hollow rotor shaft 124 rotates, and the wind wheel 11 rotates synchronously driven by the rotor shaft 124 to generate airflow, while the stator assembly remains stationary.

[0160] As shown in Figure 19 , the fan mechanism 1 includes a fan housing 13. The impeller 11 and motor 12 are located inside and spaced apart from the fan housing 13. The light-emitting assembly 22 is connected to the fan housing 13. The suspension mechanism 3 is connected to the fan housing 13, and the control assembly 21 is mounted inside the suspension mechanism 3. As shown in Figure 16 , the lighting mechanism 2 also includes a stopper 24 connected to the suspension mechanism 3 to limit the position of the conductive member 23 within the rotor shaft 124.

[0161] Conductive member 23 is typically a wire. It's easy to understand that when hollow shaft 121 is a rotor shaft 124, the high-speed rotation of rotor shaft 124 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 124, preventing it from rotating with rotor shaft 124 and preventing friction with rotor shaft 124 that could cause wear, thereby improving safety.

[0162] In the embodiment of the present application, the limiting member 24 can separate the conductive member 23 from the rotor shaft 124 , thereby preventing the rotor shaft 124 from affecting the conductive member 23 .

[0163] In some embodiments, as shown in Figure 17, the limit member 24 includes a sleeve 241, the sleeve 241 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 124, and there is a gap between the sleeve 241 and the inner wall of the rotor shaft 124, and the conductive member 23 passes through the interior of the sleeve 241.

[0164] Sleeve 241 is made of a rigid material, making its position easier to control and constrain than flexible wires. As shown in Figure 17 , sleeve 241 is fixed to suspension mechanism 3 and positioned within rotor shaft 124 . Sleeve 241 maintains a certain distance from the inner wall of rotor shaft 124, preventing contact. This ensures that sleeve 241 remains stationary regardless of whether rotor shaft 124 is rotating at high speed. Passing the wires through sleeve 241 isolates them from rotor shaft 124, thus preventing safety hazards caused by wire entanglement and wear.

[0165] In other embodiments, as shown in Figure 18, 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 124, and there is a gap between the connecting rod 242 and the inner wall of the rotor shaft 124; 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, and there is a gap between the conductive member 23 and the inner wall of the rotor shaft 124.

[0166] Connecting rod 242 is made of a rigid material, making its position and extension direction more controllable than flexible wires. As shown in Figure 18, connecting rod 242 is fixed to suspension mechanism 3 and located inside rotor shaft 124. Connecting rod 242 does not contact rotor shaft 124, so regardless of whether rotor shaft 124 rotates at high speed, connecting rod 242 remains stationary. The bottom of suspension mechanism 3 can have an opening through which conductive member 23 passes and is wrapped around or fixed to connecting rod 242. Since there is a gap between conductive member 23 fixed to connecting rod 242 and the inner wall of rotor shaft 124, safety accidents caused by wire entanglement and wear are avoided.

[0167] Optionally, as shown in FIG. 18 , a plurality of wire clamps 243 are provided on the connecting rod 242 , and the conductive member 23 is fixed to the connecting rod 242 via the wire clamps 243 .

[0168] To sum up, in the bladeless fan lamp provided in the embodiment of the present application, since the motor 12 has a hollow stator shaft 1221 or a hollow rotor shaft 124, 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.

[0169] In some embodiments of the present application, as shown in Figure 19, the fan housing 13 includes an outer shell 131 (also referred to as a cover), a first air duct component 1321 and a second air duct component 1322; the first air duct component 1321 and the second air duct component 1322 are located inside the outer shell 131 and are arranged around the air outlet 112 of the wind wheel 11. The first air duct component 1321 and the second air duct component 1322 can be collectively referred to as an air duct assembly 132. The first air duct component 1321 is adjacent to the top of the wind wheel 11, and the second air duct component 1322 is adjacent to the bottom of the wind wheel 11. A air duct space 1323 surrounding the air outlet 112 is formed between the first air duct component 1321 and the second air duct component 1322; the first air duct component 1321 and the second air duct component 1322 are close to each other at one end away from the wind wheel 11 and there is a gap between the two. The gap can be formed into an annular opening 1324 and used as an air outlet of the air duct space 1323 (or bladeless fan lamp) to discharge the airflow blown out by the wind wheel 11.

[0170] 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.

[0171] The fan mechanism 1 provided in the embodiment of the present application is an air outlet mechanism with hidden blades 115. The wind wheel 11 is located inside the fan housing 13. Accordingly, the air duct space 1323 is also formed inside the fan housing 13. As shown in Figure 19, the top of the fan housing 13 is an air inlet grille 1312, through which the air inlet 111 of the wind wheel 11 is connected to the outside. For example, an air suction port 1311 is provided at the top of the outer shell 131; the air inlet grille 1312 is provided at the air suction port 1311. The air suction port 1311 is located outside the air inlet 111 on the wind wheel 11 and is opposite to the air inlet 111. Therefore, the air suction port 1311 can also be referred to as an external air inlet 111. In some embodiments, the diameter of the air suction port 1311 can be larger than the diameter of the air inlet 111. Air duct space 1323, formed by the cooperation of first air duct member 1321 and second air duct member 1322, is located between the air outlet 112 of rotor 11 and the inner wall of fan housing 13, and has an annular shape. The combination of rotor 11, first air duct member 1321, and second air duct member 1322 draws air in from the top of fan mechanism 1. The air is then blown by rotor 11 to the inner wall of first air duct member 1321, and then out through annular opening 1324 (also called an air duct outlet), forming a ring-shaped wind that blows toward the ground, making the air flow softer.

[0172] Referring to Figure 19, first duct member 1321 and second duct member 1322 define a duct space 1323 radially relative to rotor 11. As first duct member 1321 and second duct member 1322 become closer together as they move radially away from rotor 11, the resulting duct space 1323 decreases in cross-sectional area the further it moves radially away from rotor 11. This helps concentrate the airflow from rotor 11, improving the efficiency and distance of the airflow at the duct outlet. The duct outlet is defined by the end of first duct member 1321 and the end of second duct member 1322 away from rotor 11, with the outlet pointing downward to direct airflow toward a user located below the bladeless fan lamp.

[0173] In an embodiment of the present application, as shown in Figure 20, the first air duct component 1321 and the second air duct component 1322 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 1322 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 1322 is also provided on the radial outer side of the lamp panel, it can also prevent light overflow.

[0174] Based on the above, it can be seen that the light source fixing member 221 is connected to the stator shaft 1221 and is spaced apart from the wind wheel 11. Therefore, when the wind wheel 11 rotates, the light source fixing member 221 and the second air duct component 1322 in the fan housing 13 are cooperatively connected to prevent the two from vibrating and falling. Therefore, it can be seen that the fan housing 13 including the second air duct component 1322 is stationary relative to the light source fixing member 221 and does not rotate with the wind wheel 11. In other words, in the bladeless fan lamp provided in the embodiment of the present application, the wind wheel 11 and the fan housing 13 are spaced apart, so that when the wind wheel 11 rotates, the fan housing 13 can remain stationary.

[0175] In the embodiment of the present application, as shown in FIG20 , the light-emitting assembly 22 may further include a lampshade 223. The lampshade is located on the side of the light-emitting element 222 away from the light source fixture 221, and provides a distance between the light-emitting element 222. The lampshade 223 is also coupled to the end of the second air duct member 1322 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.

[0176] Based on Figure 20, it can be seen that the suspension mechanism 3 is located above the fan housing 13, and the bottom of the suspension mechanism 3 extends into the fan housing 13, for example, through the air intake 1311 opened on the outer shell 131. The top of the fan housing 13 has an air inlet grille 1312, and the air inlet grille 1312 surrounds the bottom of the suspension mechanism 3. There is a gap along the height direction between the suspension mechanism 3 and the fan housing 13, wherein the height direction is parallel to the axis of the hollow shaft 121. In some embodiments, as shown in Figure 21, the wind wheel 11 includes a hub portion 1131, and the hub portion 1131 is opposite to the air inlet 111 of the wind wheel 11 and is used to install and fix the motor 12. The hub portion 1131 can be provided on the bottom plate 113 of the wind wheel 11, for example, and protrude toward the top plate 114. The hub portion 1131 has a mounting shaft hole 11311, through which a portion of the motor 12 passes and is located within the rotor 11. The motor 12 has a flange 1232 connected to the rotor and arranged along the rotor's circumference. At least a portion of the flange 1232 is connected to or abuts against the side of the hub portion 1131 facing the light-emitting assembly 22. Exemplarily, the flange 1232 and the hub portion 1131 are connected by screws.

[0177] As can be seen from Figures 20 and 21 , the rotor assembly 123 can also be located on the side of the base plate 113 close to the light-emitting assembly 22, and the stator shaft 1221 in the motor 12 extends into the height space of the wind wheel 11 and is further connected to the suspension mechanism 3. In some embodiments, when the rotor assembly 123 can also be located on the side of the base plate 113 close to the light-emitting assembly 22, the rotor assembly 123 can also be located in the height space of the wind wheel 11. As shown in Figure 56, the central portion of the base plate 113 in the wind wheel 11 protrudes upward to form a hub portion 1131. The rotor assembly 123 of the motor 12 is connected as the main body 126 to the recessed side of the hub portion 1131, and the rotor assembly 123 can be located in the recessed space formed by the hub portion 1131. The recessed space serves as part of the height space of the wind wheel 11.

[0178] Exemplarily, rotor assembly 123 includes a rotor sleeve 1231 and a flange 1232, wherein flange 1232 is connected to rotor sleeve 1231 and arranged along its circumference. At least a portion of flange 1232 is connected to or abuts the side of hub 1131 facing light-emitting assembly 22. A portion of rotor sleeve 1231 passes through mounting shaft hole 11311 and is located within rotor 11. As shown in Figures 20 and 21, a portion of rotor sleeve 1231 is contained within the space formed by bottom plate 113 and top plate 114 of rotor 11. When rotor assembly 123 is located within the height space, the height dimension of the portion of rotor assembly 123 located within the height space is greater than the height dimension of the portion of rotor assembly 123 located outside the height space. Thus, by accommodating rotor assembly 123 of motor 12 within rotor 11, the height dimension of the bladeless fan light is reduced, facilitating product miniaturization.

[0179] In other embodiments, the rotor assembly 123 may be located on a side of the base plate 113 near the light-emitting assembly 22, with the stator shaft 1221 in the motor 12 extending into the height space of the wind rotor 11 and further connected to the suspension mechanism 3. Alternatively, at least a portion of the flange 1232 may be connected to or abut against a side of the hub 1131 facing away from the light-emitting assembly 22, with the rotor sleeve 1231 entirely located within the wind rotor 11, thereby allowing the entire rotor assembly 123 to be concealed within the height space of the wind rotor 11.

[0180] In some embodiments, the hub portion 1131 of the wind wheel 11 has multiple concentrically arranged annular reinforcing ribs 116 on the side facing the light-emitting assembly 22. These ribs 116 are arranged around the mounting shaft hole 11311. In other words, the base plate 113 also includes multiple annular reinforcing ribs 116, which are connected to the hub portion 1131 and arranged around the mounting shaft hole 11311. These ribs 116 are concentrically arranged with the mounting shaft hole 11311, and adjacent ribs 116 are connected by reinforcing ribs 117. In some embodiments, the flange 1232 of the rotating motor 12 is connected to or abuts against at least one of the annular reinforcing ribs 116.

[0181] As shown in Figure 21, the hub portion 1131 is provided with a plurality of annular reinforcing ribs 116 and a plurality of reinforcing ribs 117. The plurality of annular reinforcing ribs 116 are arranged concentrically with the mounting shaft hole 11311, thereby strengthening the hub portion 1131. Optionally, the heights of the plurality of annular reinforcing ribs 116 vary: the annular reinforcing ribs 116 closer to the axis of the hub portion 1131 have smaller diameters and lower heights; the annular reinforcing ribs 116 further from the axis of the hub portion 1131 have larger diameters and higher heights. The height of the outermost annular reinforcing ribs 116 is less than the height of the hub portion 1131 protruding into the interior of the rotor 11. Adjacent annular reinforcing ribs 116 are connected by at least one reinforcing rib 117 to further strengthen the hub portion 1131.

[0182] In some embodiments, the base plate 113 of the wind wheel 11 further includes a connecting portion 1132 , which is connected to the outer edge of the hub portion 1131 ; the connecting portion 1132 and the outermost annular reinforcement rib 116 are connected via a reinforcement rib 117 .

[0183] For example, in the base plate 113 shown in FIG21 , the hub portion 1131 has three annular reinforcing ribs 116 extending from the inside out. The first annular reinforcing rib 116 and the second annular reinforcing rib 116 are connected by six reinforcing ribs 117, which are evenly arranged along the circumference of the annular reinforcing ribs 116. The second annular reinforcing rib 116 and the third annular reinforcing rib 116 are also connected by six reinforcing ribs 117, which correspond to the six inner reinforcing ribs 117. The third annular reinforcing rib 116 is connected to the connecting portion 1132 by six reinforcing ribs 117, which correspond to the twelve inner reinforcing ribs 117. The reinforcement structure of the bladeless fan light is described in detail in Section (II).

[0184] When assembling the motor 12, the flange 1232 of the motor 12 abuts against at least one annular reinforcing rib 116 and reinforcing rib 117, thereby ensuring good structural strength and reliable connection to the hub 1131. For example, the motor 12 is secured to the hub 1131 via bolts. As shown in FIG21 , a through-hole is defined at the intersection of the second annular reinforcing rib 116 and the reinforcing rib 117, and a through-hole is defined at a corresponding position on the flange 1232. Bolts and nuts pass through these through-holes to secure the motor 12 to the rotor 11.

[0185] Optionally, an elastic medium is also provided on the bolt. When tightened, the elastic medium is clamped between the head of the bolt and the flange 1232 . The elastic medium is used to increase the connection tightness between the flange 1232 and the wind wheel 11 .

[0186] 21 , a rotation damper 15 may be provided between the flange 1232 of the motor 12 and the bottom plate 113 of the wind wheel 11. The rotation damper 15 may also be referred to as a sealing damper, which may include a sealing ring, for example.

[0187] In other embodiments of the present application, the base plate 113 of the wind wheel 11 can also be connected to the flange 1232 of the rotating motor 12 through an in-mold injection molding process. In practice, the connected rotor and flange 1232 can be placed in the injection mold of the wind wheel 11, and then injection molding material is added to the mold so that after injection molding, the base plate 113 of the wind wheel 11 is wrapped around the outside of the flange 1232 to achieve a tight connection between the wind wheel 11 and the flange 1232; then, the other components of the motor 12 are installed on the rotor. Optionally, the flange 1232 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. The protrusion is used to strengthen the contact area between the flange 1232 and the hub portion 1131 of the wind wheel 11, thereby increasing the injection molding firmness between the hub portion 1131 of the wind wheel 11 and the flange 1232, and improving the strength and service life of the injection molded product.

[0188] The above part (I) describes the installation method between the various components of the bladeless fan lamp, such as the fan mechanism 1, the lighting mechanism 2 and the suspension mechanism 3, as well as the wiring method inside the bladeless fan lamp. On the basis of the above embodiment, the present application also improves the internal structure of at least one of the fan mechanism 1, the lighting mechanism 2 and the suspension mechanism 3 to achieve better reinforcement, anti-shake and air outlet effects. The following description will be expanded from the reinforcement structure, anti-shake structure and air outlet structure of the bladeless fan lamp. It can be understood that the structural improvements between parts (I) to (IV) can be combined with each other to provide a bladeless fan lamp with multi-faceted optimized performance.

[0189] (2) Strengthening structure of bladeless fan lamp

[0190] In related art, bladeless fans primarily utilize a turbine-type impeller 11. The rotor of a motor 12 is directly connected to the impeller 11, driving blades 115 to rotate and generate airflow. However, due to the relatively high rotational speed of the impeller 11 during fan operation, significant stress is generated at the connection between the rotor and impeller 11, which can easily lead to fracture and damage at the connection, seriously shortening the fan's service life.

[0191] The embodiment of the present application provides a fan mechanism 1, which can be, for example, the fan mechanism 1 in the bladeless fan lamp provided in the above-mentioned part (I). As shown in FIG22 , the fan mechanism 1 includes a wind wheel 11 and a motor 12; the wind wheel 11 includes a base plate 113 and a first reinforcement structure 118, the base plate 113 is provided with a first through hole 11312, the first reinforcement structure 118 is connected to the base plate 113 and surrounds at least a portion of the first through hole 11312; the motor 12 includes a rotor assembly 123 (also referred to as a rotor), the rotor assembly 123 is provided with a second through hole 12341, wherein the wind wheel 11 and the rotor assembly 123 are fastened together by a second fastener 14 that passes through the first through hole 11312 and the second through hole 12341. As shown in FIG22 and FIG23 , the installation area of ​​the rotor assembly 123 on the base plate 113 is located within the area enclosed by the first reinforcement structure 118 on the base plate 113. Exemplarily, the orthographic projection of the rotor assembly 123 on the projection plane may be located within the orthographic projection of the first reinforcement structure 118 on the projection plane, wherein the projection plane may be perpendicular to the rotation axis of the wind wheel 11 , for example, parallel to the plane where the base plate 113 is located.

[0192] In some embodiments, at least a portion of the first reinforcement structure 118 is located between the wind rotor 11 and the rotor assembly 123 and abuts against the rotor assembly 123. As described above, in this embodiment, the air inlet 111 of the wind rotor 11 is located at the top, the air outlet 112 is located on the side of the wind rotor 11 and is opened along the circumferential direction, and the bottom plate 113 of the wind rotor 11 is opposite to the air inlet 111.

[0193] The fan mechanism 1 provided in an embodiment of the present application includes a rotor 11 and a motor 12 for driving the rotor 11 to rotate. A first through-hole 11312 is formed on the base plate 113 of the rotor 11, and a second through-hole 12341 is formed on the rotor assembly 123 of the motor 12. Fasteners can pass through the first through-hole 11312 and the second through-hole 12341 to connect the base plate 113 and the rotor assembly 123 together. A first reinforcement structure 118 is also connected to the base plate 113 of the rotor 113. The first reinforcement structure 118 can be used to increase the structural strength and rigidity of the base plate 113. The installation area of ​​the rotor assembly 123 on the base plate 113 is set within the area enclosed by the first reinforcement structure 118 on the base plate 113. The portion of the base plate 113 that is connected to the rotor assembly 123 is not prone to breakage. In some embodiments, when the base plate 113 and the rotor assembly 123 are fastened together, the rotor assembly 123 abuts against the side of the first reinforcement structure 118 away from the base plate 113. Furthermore, since the first reinforcement structure 118 is arranged around the first through hole 11312, it can enhance the structural strength and rigidity of the plate body around the first through hole 11312. Therefore, when the wind wheel 11 rotates under the drive of the motor 12, the part of the base plate 113 used to connect with the rotor assembly 123 is not easy to break, thereby improving the service life of the fan mechanism 1.

[0194] In some embodiments of the present application, referring to FIG. 23 , a mounting shaft hole 11311 is provided on the base plate 113, the mounting shaft hole 11311 is spaced apart from the first through hole 11312, the rotor assembly 123 is connected to a side of the base plate 113 away from the air inlet 111, and a portion of the rotor assembly 123 passes through the mounting shaft hole 11311 to be located inside the wind wheel 11.

[0195] First reinforcement structure 118 includes a first reinforcement portion 1181, which is connected to the edge of mounting shaft hole 11311. That is, first reinforcement portion 1181 can be directly disposed on the inner wall surface of mounting shaft hole 11311. First reinforcement portion 1181 can, for example, be one of the plurality of annular reinforcement ribs 116 described above, and thus first reinforcement portion 1181 can also be referred to as a first reinforcement rib. In some embodiments, first reinforcement portion 1181 contacts the portion of rotor assembly 123 that extends through mounting shaft hole 11311.

[0196] Mounting shaft hole 11311 is used to mount motor 12. The rotor assembly 123 of motor 12 passes through mounting shaft hole 11311, so that a portion of rotor assembly 123 is located inside wind rotor 11, while the remaining portion is located outside. A first reinforcement portion 1181 is provided on the base plate 113 of wind rotor 11. First reinforcement portion 1181 is connected to the edge of mounting shaft hole 11311 and serves to increase the structural strength and rigidity of base plate 113 around mounting shaft hole 11311. As shown in FIG. 23 , when rotor assembly 123 of motor 12 is inserted into mounting shaft hole 11311 for assembly, rotor assembly 123 contacts first reinforcement portion 1181, thereby restricting the position of rotor assembly 123 within mounting shaft hole 11311 and improving the coaxiality between rotor assembly 123 of motor 12 and mounting shaft hole 11311 of wind rotor 11.

[0197] Optionally, the first reinforcement portion 1181 is an annular reinforcement rib 116 that is annularly closed.

[0198] In some embodiments of the present application, first reinforcement structure 118 further includes a second reinforcement portion 1182. Second reinforcement portion 1182 is located on a side of first through-hole 11312 away from mounting shaft hole 11311 and surrounds mounting shaft hole 11311. The center of second reinforcement portion 1182 is located on the axis of mounting shaft hole 11311. Second reinforcement portion 1182 abuts against the portion of rotor assembly 123 outside mounting shaft hole 11311. In some embodiments, second reinforcement portion 1182 directly contacts the portion of rotor assembly 123 outside mounting shaft hole 11311.

[0199] As shown in Figure 23, the distance between second reinforcement 1182 and mounting shaft hole 11311 is greater than the distance between first through-hole 11312 and mounting shaft hole 11311, resulting in second reinforcement 1182 being located on the side of first through-hole 11312 away from mounting shaft hole 11311. When rotor assembly 123 of motor 12 is inserted into mounting shaft hole 11311 for assembly, a portion of rotor assembly 123 is restrained outside mounting shaft hole 11311 and abuts against first reinforcement 1181. Second through-hole 12341 defined in this portion mates with first through-hole 11312 in base plate 113. Furthermore, this portion contacts second reinforcement 1182, thereby restraining the relative position of rotor assembly 123 and rotor 11, thereby further improving the coaxiality between rotor assembly 123 of motor 12 and mounting shaft hole 11311 of rotor 11.

[0200] In some embodiments of the present application, referring to Figures 23 and 24, the rotor assembly 123 includes a rotor core 1233 and a rotor flange 1234, the rotor core 1233 and the rotor flange 1234 are fixedly connected, and the second through hole 12341 is opened on the rotor flange 1234; the rotor core 1233 is located in the mounting shaft hole 11311, and the first reinforcement portion 1181 surrounds the rotor core 1233; the rotor flange 1234 is located on the side of the first reinforcement portion 1181 away from the base plate 113, and the circumferential edge of the rotor flange 1234 is located on the side of the second reinforcement portion 1182 close to the first reinforcement portion 1181.

[0201] Based on Figures 23 and 24, it can be seen that the second reinforcement portion 1182 defines the edge of the area enclosed by the first reinforcement structure 118 on the base plate 113, so that the area enclosed by the first reinforcement structure 118 on the base plate 113 can be determined as the area enclosed by the second reinforcement portion 1182 on the base plate 113.

[0202] Based on Figure 23, it can be seen that the rotor flange 1234 can be connected to the bottom of the rotor core 1233, wherein the central part of the rotor flange 1234 closes the bottom end of the rotor core 1233 to form the above-mentioned rotor sleeve 1231; the edge part of the rotor flange 1234 surrounding the central part can serve as the above-mentioned flange 1232.

[0203] In some embodiments, the rotor core 1233 contacts the sidewall of the first reinforcement 1181 away from the second reinforcement 1182; the rotor flange 1234 abuts the side of the first reinforcement 1181 away from the base plate 113 and contacts the sidewall of the second reinforcement 1182 near the first reinforcement 1181. In other embodiments, the rotor core 1233 may be spaced apart from the first reinforcement 1181 to prevent the first reinforcement 1181 from interfering with the rotation of the rotor core 1233; the rotor flange 1234 is spaced apart from the side of the first reinforcement 1181 away from the base plate 113 and contacts the sidewall of the second reinforcement 1182 near the first reinforcement 1181.

[0204] As shown in Figure 23, the diameter of rotor core 1233 is slightly smaller than the diameter of mounting shaft hole 11311. Rotor flange 1234 is fixedly connected to one end of rotor core 1233, and its diameter is larger than the inner diameter of mounting shaft hole 11311. During installation, rotor core 1233 is inserted into mounting shaft hole 11311. The outer wall of rotor core 1233 can contact or be spaced apart from the inner wall of first reinforcement portion 1181. The flange surface of rotor flange 1234 abuts against the end surfaces of first reinforcement portion 1181 and / or second reinforcement portion 1182, and the outer edge of rotor flange 1234 contacts the inner wall of second reinforcement portion 1182. The second through hole 12341 is located on the rotor flange 1234 and corresponds to the position of the first through hole 11312 provided on the base plate 113 of the wind rotor 11. The second fastener 14 passes through the first through hole 11312 and the second through hole 12341 to securely connect the wind rotor 11 and the motor 12. The flange surface of the rotor flange 1234 is the surface that contacts the first reinforcement structure 118 and is penetrated by the second through hole 12341.

[0205] In this embodiment of the present application, the number of second reinforcement portions 1182 can be one or more. For example, as shown in FIG25 , there is only one second reinforcement portion 1182, which surrounds the outer sides of the first through-hole 11312 and the mounting shaft hole 11311. For another example, as shown in FIG26 , there are more than one second reinforcement portion 1182. In this case, multiple second reinforcement portions 1182 are arranged radially along the mounting shaft hole 11311, and each second reinforcement portion 1182 surrounds the mounting shaft hole 11311. In this case, the innermost second reinforcement portion 1182 (i.e., the second reinforcement portion 1182 with the smallest diameter) is adjacent to the first through-hole 11312, and the rotor flange 1234 is adapted to contact the outermost second reinforcement portion 1182 (i.e., the second reinforcement portion 1182 with the largest diameter).

[0206] The second reinforcing portion 1182 can be, for example, one of the plurality of annular reinforcing ribs 116, and thus the second reinforcing portion 1182 can also be referred to as a second reinforcing rib. Optionally, the second reinforcing portion 1182 is an annular reinforcing rib 116 that is closed along the annular direction, and when there are more than one second reinforcing portion 1182, the more than one second reinforcing portion 1182 are concentrically arranged and nested in sequence.

[0207] Optionally, when the number of the second reinforcement portions 1182 is more than one, at least one connecting rib 11821 (also referred to as reinforcement rib 117 ) is connected between two adjacent second reinforcement portions 1182 , and at least one connecting rib 11821 extends sequentially along the radial direction of the mounting shaft hole 11311 .

[0208] The reinforcing ribs 117 and other second reinforcing portions 1182 except the second reinforcing portion 1182 located in the outermost circle are used to further increase the structural strength and rigidity of the plate body of the base plate 113 located around the mounting shaft hole 11311, prevent the plate body from deformation and warping, and reduce the stress in the plate body.

[0209] Optionally, in a height direction, a size of the first reinforcing portion 1181 is smaller than a size of the second reinforcing portion 1182 , wherein the height direction is parallel to the axis of the mounting shaft hole 11311 .

[0210] As shown in Figure 23, the first reinforcement portion 1181 is smaller in height, while the second reinforcement portion 1182 is larger in height. The rotor flange 1234 extends from the middle of the wind rotor 11, through the surface of the first reinforcement portion 1181 away from the base plate 113, and toward the edge of the wind rotor 11 until it contacts or is adjacent to the side wall of the second reinforcement portion 1182 near the first reinforcement portion 1181. At this point, the flange surface of the rotor flange 1234 abuts against the surface of the first reinforcement portion 1181 away from the base plate 113.

[0211] Optionally, as shown in FIG. 23 , the size of the first reinforcement structure 118 in the height direction gradually increases from the first reinforcement portion 1181 to the second reinforcement portion 1182 , wherein the height direction is parallel to the axis of the mounting shaft hole 11311 .

[0212] "Gradual increase in height" refers to the gradual increase in height of the first reinforcement structure 118. This includes both continuous and intermittent increases in height, as long as the height of the portion of the first reinforcement structure 118 farther from the mounting shaft hole 11311 is not less than the height of the portion closer to the mounting shaft hole 11311. For example, in Figure 23, the height increases from the first reinforcement portion 1181 to the second reinforcement portion 1182, then remains constant before increasing again. In general, the first reinforcement structure 118 gradually increases in height from the center to the edge of the wind rotor 11, thereby matching the height of the flange surface of the rotor flange 1234.

[0213] 24 , in some embodiments of the present application, the first reinforcement structure 118 further includes a third reinforcement portion 1183 , and the third reinforcement portion 1183 is an annular structure that is circumferentially closed along the first through hole 11312 .

[0214] The third reinforcement portion 1183 is an annular reinforcement rib 116, and thus the third reinforcement portion 1183 may also be referred to as a third reinforcement rib. The annular reinforcement portion is disposed around the first through hole 11312, thereby enhancing the structural strength and rigidity of the plate portion of the bottom plate 113 circumferentially surrounding the first through hole 11312. This prevents the bottom plate 113 from breaking when the rotor assembly 123 drives the bottom plate 113 to rotate. Furthermore, even if the bottom plate 113 breaks at the edge of the first through hole 11312, the crack will be blocked by the third reinforcement portion 1183 and will not easily extend to the plate portion outside the third reinforcement portion 1183, thereby greatly improving the service life of the fan mechanism 1.

[0215] In this embodiment, the third reinforcing portion 1183 may be connected to the edge of the first through hole 11312 , or, as shown in FIG. 23 , the third reinforcing portion 1183 and the edge of the first through hole 11312 may be separated by a certain distance.

[0216] In some embodiments of the present application, the number of the third reinforcement portions 1183 is at least two, and at least two third reinforcement portions 1183 are distributed along the circumferential direction of the mounting shaft hole 11311; the first reinforcement structure 118 also includes a fourth reinforcement portion 1184, and the two ends of the fourth reinforcement portion 1184 are respectively connected to the two third reinforcement portions 1183 adjacent in the circumferential direction of the mounting shaft hole 11311.

[0217] For example, referring to FIG. 25 , three third reinforcements 1183 are provided in an annular direction around the mounting shaft hole 11311, and any two adjacent third reinforcements 1183 are connected by a fourth reinforcement 1184. The fourth reinforcement 1184 serves to increase the structural strength and rigidity of the bottom plate 113 between two adjacent third reinforcements 1183. Furthermore, the fourth reinforcement 1184 prevents deformation and warping of this portion of the bottom plate 113, thereby reducing stress within the plate.

[0218] In some embodiments of the present application, the centers of at least two third reinforcement portions 1183 are located on the same concentric circle of the mounting shaft hole 11311 , and the fourth reinforcement portion 1184 is an arc-shaped reinforcement portion extending circumferentially along the concentric circle.

[0219] As shown in Figure 25, fourth reinforcement portion 1184 is an arc-shaped reinforcement portion, and the extension direction of multiple arc-shaped reinforcement portions is located on a concentric circle with mounting shaft hole 11311. The arc-shaped design of fourth reinforcement portion 1184 cooperates with third reinforcement portion 1183 to further improve the structural strength and rigidity of the plate body around mounting shaft hole 11311.

[0220] In some embodiments of the present application, the first reinforcement structure 118 may further include at least one of a fifth reinforcement portion 1185 and a sixth reinforcement portion 1186, both of which extend radially along the mounting shaft hole 11311. The ends of the fifth reinforcement portion 1185 are respectively connected to the first reinforcement portion 1181 and the third reinforcement portion 1183, or respectively to the second reinforcement portion 1182 and the third reinforcement portion 1183. The ends of the sixth reinforcement portion 1186 are respectively connected to the first reinforcement portion 1181 and the fourth reinforcement portion 1184, or respectively to the second reinforcement portion 1182 and the fourth reinforcement portion 1184.

[0221] As shown in Figure 27, the fifth reinforcement part 1185 is used to further increase the structural strength and rigidity of the plate body part of the bottom plate 113 between the third reinforcement part 1183 and the first reinforcement part 1181, as well as the structural strength and rigidity of the plate body part of the bottom plate 113 between the third reinforcement part 1183 and the second reinforcement part 1182, to prevent the plate body from deformation and warping, and to reduce the stress inside the plate body.

[0222] The sixth reinforcement portion 1186 is used to further increase the structural strength and rigidity of the plate body portion of the bottom plate 113 between the first reinforcement portion 1181 and the fourth reinforcement portion 1184, as well as the structural strength and rigidity of the plate body portion of the bottom plate 113 between the second reinforcement portion 1182 and the fourth reinforcement portion 1184, to prevent deformation and warping of the plate body, and to reduce stress inside the plate body.

[0223] Optionally, there are multiple fifth reinforcement portions 1185, and two of the multiple fifth reinforcement portions 1185 are located on opposite sides of the same third reinforcement portion 1183, and the extension directions of the two fifth reinforcement portions 1185 pass through the center of the same third reinforcement portion 1183.

[0224] As shown in Figure 27, multiple third reinforcements 1183 and multiple arc-shaped fourth reinforcements 1184 cooperate to form an annular structure. A first annular spacer is formed between the annular first reinforcement 1181 and the multiple third reinforcements 1183 and multiple fourth reinforcements 1184 in the overall annular structure. A second annular spacer is formed between the annular second reinforcement 1182 and the multiple third reinforcements 1183 and multiple fourth reinforcements 1184 in the overall annular structure. Multiple fifth reinforcements 1185 are arranged circumferentially within the first annular spacer, and multiple fifth reinforcements 1185 are also arranged circumferentially within the second annular spacer. At least one third reinforcement 1183 is simultaneously connected to two fifth reinforcements 1185, which are located within the first and second annular spaces, respectively. These two fifth reinforcements 1185 extend in the same direction, passing through the center of the third reinforcement 1183 to which they are connected.

[0225] Optionally, there are multiple sixth reinforcement portions 1186 , and there are two sixth reinforcement portions 1186 among the multiple sixth reinforcement portions 1186 , which are respectively located on opposite sides of the fourth reinforcement portion 1184 and are both connected to the middle position of the fourth reinforcement portion 1184 .

[0226] Continuing with FIG27 , a plurality of sixth reinforcements 1186 arranged in an annular direction may be provided within the first annular interval, and a plurality of sixth reinforcements 1186 arranged in an annular direction may also be provided within the second annular interval. At least one fourth reinforcement 1184 is simultaneously connected to two sixth reinforcements 1186, which are located within the first annular interval and the second annular interval, respectively, and extend in the same direction. The two sixth reinforcements 1186 are both connected to the middle of the fourth reinforcement 1184, so that each of the two sixth reinforcements 1186 is equidistant from the two first reinforcements 1181 located at either end of the fourth reinforcement 1184.

[0227] As shown in Figure 27, the third reinforcement part 1183 is evenly arranged along the circumferential direction of the mounting shaft hole 11311, and the fifth reinforcement part 1185 and the sixth reinforcement part 1186 are evenly arranged along the circumferential direction of the mounting shaft hole 11311, so that the first reinforcement structure 118 is a centrally symmetrical structure, and the center of symmetry of the centrally symmetrical structure is located on the axis of the mounting shaft hole 11311, thereby ensuring that the plate body around the mounting shaft hole 11311 is evenly reinforced as a whole, thereby further ensuring the reinforcement effect.

[0228] In the fan mechanism 1 provided in some embodiments of the present application, as shown in Figures 22 and 23, the diameter of the rotor flange 1234 is smaller than the diameter of the second reinforcement portion 1182 located in the innermost circle. At this time, the rotor flange 1234 will abut against the first reinforcement portion 1181, the third reinforcement portion 1183, the fourth reinforcement portion 1184 in the first reinforcement structure 118, and the fifth reinforcement portion 1185 and the sixth reinforcement portion 1186 located in the first annular interval, and may also abut against the fifth reinforcement portion 1185 and the sixth reinforcement portion 1186 located at least partially in the second annular interval.

[0229] In some embodiments, as shown in Figure 28, in the height direction, the size of the first reinforcement part 1181 is the smallest, and the sizes of the fifth reinforcement part 1185 and the sixth reinforcement part 1186 connected to the first reinforcement part 1181 are equal to the size of the first reinforcement part 1181; the size of the third reinforcement part 1183 and the size of the fourth reinforcement part 1184 are equal, and both are larger than the size of the first reinforcement part 1181; the size of the fifth reinforcement part 1185 and the size of the sixth reinforcement part 1186 located in the second annular interval are equal, and both are equal to the size of the third reinforcement part 1183; the sizes of multiple second reinforcement parts 1182 are equal and larger than the size of the third reinforcement part 1183, and the size of the reinforcement rib 117 located between adjacent second reinforcement parts 1182 is equal to the size of the second reinforcement part 1182, so that the first reinforcement structure 118 as a whole presents a structure with gradually increasing size in the height direction.

[0230] In this embodiment of the present application, the direction from the base plate 113 of the rotor 11 along the rotation axis toward the top of the rotor 11 is defined as the height direction, and the closer to the top of the rotor 11, the higher the height. Different portions of the first reinforcement structure 118 have different heights, which are adapted to the shape of the flange surface of the rotor flange 1234.

[0231] In the above embodiment, the first reinforcement structure 118 may be a reinforcement rib. In other embodiments, the first reinforcement structure 118 may also be a reinforcement plate.

[0232] In some embodiments of the present application, as shown in FIG29 , the base plate 113 includes a hub portion 1131 and a connecting portion 1132, which are connected sequentially from the center to the edge of the base plate 113. The hub portion 1131 is used to mount the motor 12, with the mounting shaft hole 11311 and the first reinforcement structure 118 both located on the hub portion 1131. The connecting portion 1132 is used to connect to the blades 115 of the wind rotor 11. The hub portion 1131 is taller than the connecting portion 1132, and its height is parallel to the rotation axis of the wind rotor 11.

[0233] As shown in FIG29 , the hub portion 1131 is closer to the top of the wind rotor 11 than the connecting portion 1132, that is, the hub portion 1131 is higher. The first reinforcement structure 118 is connected to the side of the hub portion 1131 away from the top of the wind rotor 11. Optionally, the bottom of the first reinforcement structure 118 and the bottom surface of the connecting portion 1132 are located at the same height, where the bottom of the first reinforcement structure 118 refers to the portion away from the hub portion 1131, and the bottom surface of the connecting portion 1132 refers to the surface facing away from the top of the wind rotor 11.

[0234] In some embodiments, as shown in FIG29 , the base plate 113 faces the air inlet 111, and the rotor assembly 123 is connected to the side of the base plate 113 facing away from the air inlet 111, and partially passes through the mounting shaft hole 11311 and is located within the wind rotor 11. In other embodiments, the rotor assembly 123 is located on the side of the base plate 113 facing away from the air inlet 111 and is connected to the base plate 113, so that the rotor assembly 123 can be located entirely below the base plate 113. In this case, the hub portion 1131 protrudes relative to the connecting portion 1132 toward the air inlet 111, and the rotor assembly 123 located below the base plate 113 can be located within the height space formed by the protrusion of the hub portion 1131. Alternatively, in another embodiment, the rotor assembly 123 is connected to the side of the base plate 113 facing the air inlet 111 and is located entirely within the wind rotor 11.

[0235] 29 , the bottom plate 113 further includes a transition portion 1133 connected between the hub portion 1131 and the connecting portion 1132. In some embodiments, the transition portion 1133 is inclined relative to the hub portion 1131 and is inclined relative to the connecting portion 1132.

[0236] In some embodiments of the present application, as shown in FIG30 , the fan mechanism 1 further includes a second reinforcement structure 119 , which is disposed on the transition portion 1133 and connected to the second reinforcement portion 1182 . The second reinforcement structure 119 is used to improve the structural strength and rigidity of the transition portion 1133 .

[0237] Exemplarily, the second reinforcement structure 119 is connected to the outermost second reinforcement portion 1182. In this embodiment, when there is only one second reinforcement portion 1182, it is both the "innermost second reinforcement portion 1182" and the "outermost second reinforcement portion 1182." When there are more than one second reinforcement portion 1182, the "outermost second reinforcement portion 1182" refers to the second reinforcement portion 1182 with the largest diameter.

[0238] As can be seen from FIG30 , the second reinforcement structure 119 and the first reinforcement structure 118 are located on the same side of the bottom plate 113, for example, on the side of the bottom plate 113 facing away from the air inlet 111. The first reinforcement structure 118 is provided on the hub portion 1131 of the bottom plate 113, while the second reinforcement structure 119 is provided on the bottom transition portion 1133. Therefore, the second reinforcement structure 119 is located outside the area enclosed by the first reinforcement structure 118 on the bottom plate 113.

[0239] Optionally, referring again to FIG. 30 , the second reinforcement structure 119 includes at least one seventh reinforcement portion 1191. Each seventh reinforcement portion 1191 extends radially from the mounting shaft hole 11311, and the height of the seventh reinforcement portion 1191 decreases as it moves away from the mounting shaft hole 11311. The seventh reinforcement portion 1191 and the aforementioned connecting rib 11821 can serve as one of the reinforcement ribs 117 described in Section (I) above.

[0240] As shown in Figure 30, the cross-sectional shape of the seventh reinforcement portion 1191 is a triangle, and the base of the triangle is connected to the second reinforcement portion 1182 located in the outermost circle, and the vertex of the triangle extends toward the third reinforcement portion 1183 away from the mounting shaft hole 11311, wherein the extension direction of the base of the triangle is parallel to the height direction.

[0241] In some embodiments of the present application, each seventh reinforcement portion 1191 passes through the center of the corresponding third reinforcement portion 1183, and at least one fifth reinforcement portion 1185 is arranged between the seventh reinforcement portion 1191 and the corresponding third reinforcement portion 1183, and the extension direction of at least one fifth reinforcement portion 1185 is the same as the extension direction of the seventh reinforcement portion 1191.

[0242] As shown in Figure 31, each seventh reinforcement portion 1191 is provided corresponding to a third reinforcement portion 1183, wherein the seventh reinforcement portion 1191 extends radially along the mounting shaft hole 11311 and passes through the center of the corresponding third reinforcement portion 1183. A fifth reinforcement portion 1185 is further provided between the corresponding seventh reinforcement portion 1191 and the third reinforcement portion 1183, and the fifth reinforcement portion 1185 and the seventh reinforcement portion 1191 are located in the same radial direction of the mounting shaft hole 11311.

[0243] In some embodiments of the present application, in addition to increasing the structural strength and rigidity of the base plate 113 by setting a first reinforcement structure 118 and a second reinforcement structure 119 to avoid fracture at the connection between the base plate 113 and the rotor flange 1234, it is also possible to reduce the interaction force between the base plate 113 and the rotor flange 1234 to avoid fracture and damage at the connection.

[0244] As shown in FIG. 32 , the fan mechanism 1 further includes a shock-absorbing member, which is sandwiched between the first reinforcement structure 118 of the wind wheel 11 and the rotor assembly 123 of the motor 12 .

[0245] The shock absorber provides a certain degree of cushioning and shock absorption, protecting the rotor 11 and base plate 113 to a certain extent, making them less susceptible to breakage and damage. For example, the shock absorber is disposed between the first reinforcement structure 118 and the rotor flange 1234, and between the first through-hole 11312 and the second through-hole 12341. Thus, the shock absorber is disposed in the rotor 11 to reduce vibration during the rotation of the rotor 11, and thus can be referred to as a rotating shock absorber 15.

[0246] As shown in FIG32 , the rotation damper 15 is disposed between the first reinforcement structure 118 and the rotor flange 1234, and is located between the first through-hole 11312 and the second through-hole 12341. The second fastener 14 passes through the rotation damper 15. The rotation damper 15 abuts against the side of the third reinforcement portion 1183 in the first reinforcement structure 118 that is away from the base plate 113. The circumferential edge of the rotation damper 15 is located between the side of the second reinforcement portion 1182 that is closer to the first reinforcement portion 1181 and the circumferential edge of the rotor flange 1234. As described above, the first reinforcement structure 118 includes a plurality of arcuate third reinforcement portions 1183, each extending along a concentric circle with the mounting shaft hole 11311, and the concentric circle passes through the first through-hole 11312.

[0247] To sum up, in the fan mechanism 1 provided in the embodiment of the present application, a first through hole 11312 is provided on the base plate 113 of the wind wheel 11, and a second through hole 12341 is provided on the rotor flange 1234 of the motor 12. The fastener can pass through the first through hole 11312 and the second through hole 12341 and connect the base plate 113 and the rotor flange 1234 together, thereby realizing the connection between the wind wheel 11 and the motor 12. Among them, a first reinforcement structure 118 is provided on the hub portion 1131 of the base plate 113 of the wind wheel 11, and a second reinforcement structure 119 is provided on the connecting portion 1132 of the base plate 113. The first reinforcement structure 118 and the second reinforcement structure 119 cooperate with each other, so that the structural strength and rigidity of the base plate 113 are significantly improved. When driven to rotate by the motor 12, it is not easy to deform and warp, and is even less likely to break and damage. A shock absorber is also provided between the first reinforcement structure 118 and the rotor flange 1234 to further protect the base plate 113 of the wind wheel 11, so that the service life of the fan mechanism 1 is greatly extended.

[0248] The embodiment of the present application further provides a blowing device, which includes the fan mechanism 1 described in any of the above embodiments. The blowing device can be, for example, a bladeless fan lamp.

[0249] In the blowing device (bladeless fan lamp) provided in the embodiment of the present application, due to the adoption of the above-mentioned fan mechanism 1, the structural strength and rigidity of the base plate 113 of the wind wheel 11 are significantly improved. Therefore, when the wind wheel 11 rotates under the drive of the motor 12, the part of the base plate 113 used for connection with the rotor assembly 123 is not easy to deform and warp, and is less likely to break and damage, thereby extending the service life of the fan mechanism 1.

[0250] (3) Anti-shake structure of bladeless fan light

[0251] In related art, the fan lamp's air blowing and lighting functions are performed by a fan module and a lamp module, respectively, which are usually directly connected. However, when the air blowing function is activated, the high-speed rotation of the fan module's blades can easily cause high-frequency vibrations throughout the entire unit, generating noise and causing the light provided by the lamp module to be unstable.

[0252] In the above embodiment, a rotating shock-absorbing member 15 is provided in the fan mechanism 1, which is clamped between the rotor assembly 123 of the motor 12 and the base plate 113 of the impeller 11, to reduce vibration between the motor 12 and the impeller 11. In the embodiment of the present application, a shock-absorbing assembly 26 can also be provided in the lighting mechanism 2 to reduce the impact of vibration generated by the operation of the fan mechanism 1 on the lighting mechanism 2, especially the light-emitting assembly 22 in the lighting mechanism 2, thereby realizing the anti-shake function of the bladeless fan light.

[0253] An embodiment of the present application provides a bladeless fan lamp that can realize an anti-shake function, as shown in Figures 33 and 34, the bladeless fan lamp includes a fan mechanism 1 and a lighting mechanism 2; the fan mechanism 1 includes a duct assembly 132 and a wind wheel 11, the duct assembly 132 is arranged around the wind wheel 11, and is used to enclose a duct space 1323 (also referred to as an air duct), and the duct space 1323 is connected to the air outlet 112 of the wind wheel 11; the lighting mechanism 2 includes a light-emitting assembly 22 and a shock-absorbing assembly 26, the light-emitting assembly 22 is located outside the air duct and is connected to the air duct assembly 132, and the light-emitting assembly 22 is spaced apart from the wind wheel 11; the shock-absorbing assembly 26 is located between the light-emitting assembly 22 and the duct assembly 132, and / or, between the light-emitting assembly 22 and the wind wheel 11.

[0254] The bladeless fan lamp provided in the embodiment of the present application includes a fan mechanism 1 and a lighting mechanism 2. The fan mechanism 1 can form a ring-shaped air duct space 1323, and the airflow generated by the wind wheel 11 is blown out through the air duct to realize the blowing function; the lighting mechanism 2 is arranged outside the air duct space 1323 to avoid blocking the air outlet. The lighting mechanism 2 includes a light-emitting component 22 and a shock-absorbing component 26. The light-emitting component 22 is used to emit light to realize the lighting function. The shock-absorbing component 26 is arranged between the air duct component 132 and the light-emitting component 22, and / or, between the wind wheel 11 and the light-emitting component 22, to separate the fan mechanism 1 and the light-emitting component 22. Therefore, when the wind wheel 11 rotates at high speed, the shock-absorbing component 26 can play a role of buffering and shock absorption, effectively weakening the whole machine jitter caused by the high-speed rotating wind wheel 11 during the operation of the fan mechanism 1, reducing the whole machine operation noise, and ensuring the stability of light when the blowing function and the lighting function are enabled at the same time.

[0255] In some embodiments of the present application, as shown in FIG. 33 , the light emitting assembly 22 is located on a side of the air duct assembly 132 close to the wind wheel 11 and below the wind wheel 11 .

[0256] In this embodiment, referring to FIG33 , the air inlet 111 of the wind wheel 11 is located at the top of the wind wheel 11, and the air outlet 112 is circumferentially opened on the side of the wind wheel 11; the air duct assembly 132 is circumferentially arranged around the wind wheel 11 and is connected to the air outlet 112 of the wind wheel 11 to ensure that the airflow generated by the wind wheel 11 can enter the air duct.

[0257] Optionally, in the embodiment of the present application, the number of blades 115 in the wind wheel 11 is an odd number. Setting the number of blades 115 to an odd number can reduce resonance sound. For example, the number of blades 115 can be nine.

[0258] Optionally, the wind wheel 11 in the embodiment of the present application is a backward-inclined wind wheel 11. Compared with the forward-inclined wind wheel 11, the backward-inclined wind wheel 11 has lower noise.

[0259] Because fan lights are typically mounted on a ceiling, the light-emitting assembly 22 is typically located at the bottom of the fan. For example, the light-emitting assembly 22 can be located below the wind wheel 11, with the air duct assembly 132 surrounding the outer periphery of the light-emitting assembly 22. The wind wheel 11 can rotate at high speeds, driven by a driver (e.g., a motor 12), to generate airflow. In this embodiment, the light-emitting assembly 22 is not connected to the wind wheel 11, and a certain distance is maintained between them to prevent the high-speed rotation of the wind wheel 11 from affecting the light-emitting assembly 22.

[0260] As shown in Figure 35, in some embodiments, the light-emitting assembly 22 may include a light source fixing member 221, a light-emitting element 222 and a lampshade 223; the edge portion of the light source fixing member 221 is connected to the air duct assembly 132, and the light-emitting element 222 is installed on the side of the light source fixing member 221 away from the wind wheel 11; the lampshade 223 is located on the side of the light-emitting element 222 away from the light source fixing member 221, and is connected to the air duct assembly 132.

[0261] The light source fixture 221 may be, for example, a lamp panel. A mounting position for at least one light-emitting element 222 is provided on the side of the lamp panel facing away from the wind wheel 11. The light-emitting element 222 is mounted in a corresponding mounting position on the lamp panel. The light-emitting element 222 may, for example, include at least one LED light panel for providing illumination. As shown in Figures 33 to 35 , a lampshade 223 is located below the light-emitting element 222 and is connected to the air duct assembly 132. The lampshade 223 serves as an eye protector, preventing damage caused by direct viewing of the light-emitting element 222. It also prevents dust from entering the interior of the lighting mechanism 2 and causing malfunction of the light-emitting element 222.

[0262] In some embodiments of the present application, as shown in Figure 37, the air duct assembly 132 may include a first air duct component 1321 and a second air duct component 1322, and the first air duct component 1321 and the second air duct component 1322 are arranged at intervals and form an air duct; the first air duct component 1321 and the second air duct component 1322 are located on a side away from the wind wheel 11, and the second air duct component 1322 and the wind wheel 11 are arranged at intervals; the light source fixing part 221 is connected to one end of the second air duct component 1322 adjacent to the wind wheel 11, and the lampshade 223 is connected to one end of the second air duct component 1322 away from the wind wheel 11.

[0263] As shown in FIG36 , the light source fixing member 221 and the air duct assembly 132 are independently provided. The shock absorbing assembly 26 includes a first shock absorbing member 261, which is sandwiched between the connection between the light source fixing member 221 and the second air duct member 1322. In other embodiments, the light source fixing member 221 and the second air duct member 1322 are integral components, so that no shock absorbing member may be provided between the light source fixing member 221 and the second air duct member 1322. In this case, the light source fixing member 221 may serve as part of the air duct assembly 132. The first shock absorbing member 261 may be sandwiched between the lampshade 223 and the aforementioned integral component, that is, the first shock absorbing member 261 may be sandwiched between the connection between the lampshade 223 and the air duct assembly 132. As shown in FIG36 , the first shock absorbing member 261 may be sandwiched between the connection between the lampshade 223 and the second air duct member 1322. For example, the edge of the lampshade 223 can be bent toward the rotation axis of the wind wheel 11 to form a vertical hem. The second air duct member 1322 can be provided with a circumferentially extending rib that can abut against the hem of the lampshade 223. The first shock absorber 261 is clamped between the hem of the lampshade 223 and the rib of the second air duct member 1322.

[0264] In some embodiments, when the light source fixture 221 and the second air duct member 1322 are an integral component, a vibration damper may be provided between the integral component and the first air duct member 1321. For example, a raised structure, such as the air guide 1331 described below, may be provided on the inner side of the first air duct member 1321. The bottom end of the air guide 1331 abuts against the second air duct member 1322 in the integral component. The vibration damper may be provided at the connection between the air guide 1331 and the integral component.

[0265] The first and second duct members 1321, 1322 are spaced apart and serve as opposing duct walls, forming a duct space 1323 suitable for airflow between them. Neither the first nor the second duct member 1321, 1322 is connected to the rotor 11 and is spaced apart from the rotor 11 to prevent interference with the high-speed rotation of the rotor 11. The light source fixture 221 and the lampshade 223 are both connected to the second duct member 1322 for securement.

[0266] As shown in FIG38 , in some embodiments, the second air duct member 1322 may be provided with a support member 1325 and a positioning member 1326. Both the support member 1325 and the positioning member 1326 are connected to the side of the second air duct member 1322 facing away from the air duct space 1323, and the support member 1325 is closer to the wind wheel 11 than the positioning member 1326. The light source fixture 221 includes a central portion 2213 and a flange portion 2214. The central portion 2213 is used to mount the light-emitting element 222, and the flange portion 2214 is connected to the outer periphery of the central portion 2213. As shown in FIG39 , the central portion 2213 is located on the side of the support member 1325 away from the second air duct member 1322 and is connected to the support member 1325. The flange portion 2214 is located on the side of the positioning member 1326 away from the second air duct member 1322. The above-mentioned support member 1325 is provided on the second air duct component 1322 and can also be referred to as a support portion, and the positioning member 1326 can also be referred to as a positioning portion.

[0267] The support member 1325 is configured to engage with the central portion 2213 of the light source fixture 221 to secure the light source fixture 221 to the second duct member 1322. The positioning member 1326 engages with the flange portion 2214 of the light source fixture 221 to restrict the position of the light source fixture 221, thereby improving the ease of connection and alignment between the light source fixture 221 and the second duct member 1322.

[0268] For example, as shown in FIG38 , the light source fixture 221 is generally circular, with a central portion 2213 located in the middle of the light source fixture 221 and having a circular shape. The flange portion 2214 is located at the edge of the light source fixture 221 and is connected to the outer periphery of the central portion 2213, forming a ring. The support member 1325 and the positioning member 1326 are both arranged circumferentially around the second air duct member 1322. The inner diameter of the positioning member 1326 is slightly larger than the diameter of the central portion 2213 of the light source fixture 221, while the outer diameter of the positioning member 1326 is smaller than the outer diameter of the flange portion 2214. When assembling the light source fixture 221 onto the second air duct member 1322, the light source fixture 221 is simply placed directly into the inner circle formed by the positioning member 1326 and then adjusted relative to the central portion 2213. At this point, the flange portion 2214 of the light source fixture 221 overlaps the surface of the positioning member away from the second air duct member 1322.

[0269] 38 , the central portion 2213 and the support member 1325 are connected by fasteners. For example, the central portion 2213 and the support member 1325 each have screw holes, and screws pass through the two screw holes to connect the light source fixing member 221 and the second air duct member 1322 together.

[0270] In some embodiments of the present application, the lampshade 223 can be detachably secured to the second air duct member 1322 by snapping. As shown in FIG40 , the second air duct member 1322 is further provided with a first snap-fitting member 1327 connected to a side of the second air duct member 1322 away from the air duct; the lampshade 223 is provided with a second snap-fitting member 2231 that snaps into engagement with the first snap-fitting member 1327.

[0271] In some embodiments of the present application, the shock absorbing assembly 26 may be provided only between the connection point between the air duct assembly 132 and the lighting mechanism 2 , or may be provided between any possible contact positions between the air duct assembly 132 and the lighting mechanism 2 .

[0272] As shown in Figure 36, the shock absorbing assembly 26 may include a first shock absorbing member 261, which is clamped between the connection between the light source fixing member 221 and the air duct assembly 132, and / or, clamped between the connection between the lampshade 223 and the air duct assembly 132.

[0273] As shown in FIG39 , the first shock absorbing member 261 includes at least one of a first shock absorbing portion and a second shock absorbing portion 2612. The first shock absorbing member 261 can be clamped between the light source fixing member 221 and the second air duct member 1322. The first shock absorbing portion is sandwiched between the central portion 2213 of the light source fixing member 221 and the positioning member 1326 on the second air duct member 1322, and the second shock absorbing portion 2612 is sandwiched between the flange portion 2214 of the light source fixing member 221 and the positioning member 1326.

[0274] As previously mentioned, the high-speed rotation of the wind wheel 11 during operation can easily cause high-frequency vibration of the entire device. The provision of the first shock absorber 261 can reduce vibration of the entire device and prevent resonance. Optionally, the first shock absorber 261 (at least one of the first shock absorbing portion and the second shock absorbing portion 2612) can be a soft shock absorber such as a rubber ring or a silicone ring, and tightly fit with the contacting structure. In this case, the soft shock absorber can also act as a seal, effectively preventing dust from being blown into the interior of the lighting mechanism 2 from the outlet of the air duct.

[0275] In some embodiments of the present application, as described above and shown in Figure 41, the fan mechanism 1 also includes an outer rotor motor 12, which is located inside the wind wheel 11 and includes an inner stator assembly 122 and a rotor assembly 123; the inner stator assembly 122 of the outer rotor motor 12 is connected to the light source fixing member 221, and the rotor assembly 123 of the outer rotor motor 12 is sleeved on the outside of the inner stator assembly 122 and connected to the wind wheel 11 to drive the wind wheel 11 to rotate; the shock absorber assembly 26 includes a second shock absorber 262, and the second shock absorber 262 is clamped between the inner stator assembly 122 and the light source fixing member 221.

[0276] After the outer rotor motor 12 is started, the inner stator assembly 122 remains stationary, while the rotor assembly 123 rotates around the inner stator assembly 122. The impeller 11 is directly connected to the rotor assembly 123, rotating synchronously with it to generate airflow. In this embodiment, as shown in Figure 41, both ends of the inner stator assembly 122 extend axially beyond the rotor assembly 123.

[0277] The inner stator assembly 122 is fixedly connected to the light source fixture 221, and the connection method can be, for example, screw connection, riveting, clamping, etc. For example, the stator assembly includes a stator shaft 1221 and a stator sleeve 1222. The stator shaft 1221 passes through and is connected to the stator sleeve 1222. A first assembly hole is formed at one end of the stator sleeve 1222 near the light source fixture 221. A second assembly hole is formed on the light source fixture 221. The third fastener 27 passes through the first assembly hole and the second assembly hole to fasten the light source fixture 221 to the stator sleeve 1222 of the stator assembly. A second shock absorber 262 is also provided between the light source fixture 221 and the stator sleeve 1222. The second shock absorber 262 rests on the end surface of the stator sleeve 1222 facing the light source fixture 221, and is used to improve the connection stability between the stator assembly and the light source fixture 221, while also playing a role in shock absorption and anti-shake. Exemplarily, the second shock-absorbing member 262 is a soft sealing ring.

[0278] In summary, in the anti-shake bladeless fan lamp provided in the embodiment of the present application, the light-emitting assembly 22 can be disposed below the wind wheel 11, and the air duct assembly 132 is disposed around the wind wheel 11 and the light-emitting assembly 22. The light-emitting assembly 22 is connected to the second air duct member 1322 in the air duct assembly 132, and both the air duct assembly 132 and the light-emitting assembly 22 are spaced apart from the wind wheel 11. The air duct assembly 132 can form an air duct space 1323 along the circumference of the wind wheel 11. The air duct space 1323 is connected to the air outlet 112 of the wind wheel 11. The airflow generated by the wind wheel 11 is blown out through the air duct to achieve a blowing function. The lighting mechanism 2 also includes a shock-absorbing assembly 26 for separating the fan mechanism 1 from the light-emitting assembly 22, wherein a first shock-absorbing member 261 is disposed between the connection between the light source fixing member 221 and the second air duct member 1322 of the light-emitting assembly 22, and / or between the lampshade 223 and the second air duct member 1322, for example, between the positioning members 1326 on the light source fixing member 221 and the second air duct member 1322; and a second shock-absorbing member 262 is disposed between the light source fixing member 221 and the stator sleeve 1222. The first shock-absorbing member 261 and the second shock-absorbing member 262 can play a role in buffering and shock-absorbing, effectively weakening the whole machine vibration caused by the high-speed rotating impeller 11 during the operation of the fan mechanism 1, reducing the whole machine operating noise, and ensuring the stability of light when the blowing function and the lighting function are enabled simultaneously, thereby improving the performance of the anti-shake bladeless fan lamp.

[0279] (4) The air outlet structure of the bladeless fan lamp

[0280] In the related art, bladeless fans mainly use a wind wheel to stir the airflow and send it into the air duct. However, the airflow diverges greatly in the air duct and the flow is not uniform, resulting in a small air volume at the air outlet; moreover, the airflow blown out from the air outlet will blow directly on the surface of the human skin, which is prone to cause adverse physical sensations and cause the user to feel unwell and have symptoms such as colds.

[0281] The present invention provides a fan mechanism capable of producing an annular airflow. This fan mechanism is a bladeless fan mechanism. In normal use, the fan blades 11 are hidden within the housing, providing improved aesthetics and safety. This fan mechanism can be applied to heat dissipation devices, such as bladeless electric fans and bladeless fan lamps.

[0282] As shown in Figures 42 and 43, the fan mechanism 1 provided in the embodiment of the present application includes a wind wheel 11, a duct assembly 132 and a guide assembly 133; the wind wheel 11 has a plurality of blades 115, and the plurality of blades 115 are arranged in a vortex shape; the duct assembly 132 surrounds the wind wheel 11 and forms a duct space 1323 along the circumferential direction of the wind wheel 11, and the duct space 1323 is connected to the air outlet 112 of the wind wheel 11; the guide assembly 133 is located inside the duct space 1323 and is connected to the duct assembly 132, and the guide assembly 133 is used to guide the airflow blown out of the wind wheel 11 to flow in the circumferential direction, wherein the guide direction of the guide assembly 133 is opposite to the vortex direction of the plurality of blades 115.

[0283] In the embodiment of the present application, opposite direction means that the extension direction from the center of the wind wheel (or the leading edge of the blade) to the trailing edge of the blade is towards a different side from the guide direction of the guide component 3, and should not be understood as indicating that the guide direction and the vortex direction can only be 180° opposite.

[0284] As shown in Figures 42 and 43, the aforementioned "vortex arrangement" means that the distance between two adjacent blades 115 gradually increases in the direction from the center of the wind rotor 11 toward the edge (away from the rotation axis of the wind rotor 11), and the direction from the leading edge 1151 of the blade 115 toward its trailing edge 1152 intersects with the radial direction of the wind rotor 11, where the leading edge 1151 is the edge of the blade 115 on one side close to the rotation axis of the wind rotor 11, and the trailing edge 1152 is the edge of the blade 115 on the one side away from the rotation axis. This vortex shape can also be called a spiral shape. The vortex (or spiral direction) can be determined as the direction from the leading edge 1151 of the blade 115 toward its trailing edge 1152, for example, in a clockwise direction in Figure 43. There is a gap between two connected blades 115 to divide the air outlet 112 of the wind wheel 11 into multiple air outlet gaps 13241. When the motor 12 rotates, the air flow is discharged in a circular direction through the air outlet 112. The air outlet direction of the air outlet 112 is consistent with the vortex direction of the blade 115. For example, in Figure 43, the air outlet 112 discharges air clockwise.

[0285] The flow diversion direction of the flow diversion assembly 133 can be determined as each flow diversion member 1331 in the flow diversion assembly 133 points from its leading edge 1151 to its trailing edge 1152, where the leading edge 1151 of the flow diversion member 1331 is the edge of the flow diversion member 1331 on the side closest to the rotation axis of the wind rotor 11, and the trailing edge 1152 of the flow diversion member 1331 is the edge of the flow diversion member 1331 on the side away from the rotation axis. In Figure 43, the flow diversion direction of the flow diversion assembly 133 is counterclockwise.

[0286] In the fan mechanism provided in the embodiment of the present application, the air duct assembly 132 forms an air duct space 1323 in the annular direction of the wind wheel 11. The air duct space 1323 is connected to the air outlet 112 of the wind wheel 11, so that the air flow generated by the rotation of the wind wheel 11 (the wind wheel 11 can be driven by a motor 12, for example, which is not shown in the figure) flows out from the air outlet 112, flows through the air duct space 1323 and is then blown out. Among them, since the air duct space 1323 is provided with a guide assembly 133, the guide direction of the guide assembly 133 is opposite to the vortex direction (spiral direction) of the blade 115, and can guide the air flow in the air duct space 1323 to flow in an annular direction, so the air flow blown out from the air duct space 1323 is an annular airflow, which has a softer blowing effect on the skin on the human body. Therefore, when the fan mechanism 1 provided in the embodiment of the present application is used, compared with the fan with direct airflow in the related art, it brings better physical comfort to the user and protects the user's health.

[0287] In an embodiment of the present application, as shown in Figures 42 and 43 , the blades 115 used in the wind rotor 11 may be spiral blades 115, such that the trailing edge 1152 of the blade 115 is twisted relative to the leading edge 1151 of the blade 115. In some embodiments, the distance between the top of the leading edge 1151 of the blade 115 and the rotation axis of the wind rotor 11 is greater than the distance between the bottom of the leading edge 1151 and the rotation axis of the wind rotor 11; and the distance between the top of the trailing edge 1152 of the blade 115 and the rotation axis of the wind rotor 11 is less than the distance between the bottom of the leading edge 1151 and the rotation axis of the wind rotor 11. In some embodiments, the spiral direction of the blade 115 may be the same as the swirl direction of the blade 115.

[0288] The multiple blades 115 are arranged in a spiral shape, and the flow guide direction of the flow guide assembly 133 needs to be opposite to the swirl direction of the blades 115. For example, if the swirl direction of the blades 115 of the wind rotor 11 is right-handed, corresponding to a clockwise direction, the flow guide direction of the flow guide assembly 133 is correspondingly counterclockwise. For another example, if the swirl direction of the blades 115 of the wind rotor 11 is left-handed, corresponding to a counterclockwise direction, the flow guide direction of the flow guide assembly 133 is correspondingly clockwise.

[0289] Referring to Figure 43, in some embodiments, the guide assembly 133 may include a plurality of guide members 1331, each guide member 1331 having a guide surface 13311, wherein the arrangement direction of the plurality of guide surfaces 13311 is opposite to the vortex direction of the blade 115, and the airflow blown out by the wind wheel 11 is suitable for flowing along the arrangement direction of the plurality of guide surfaces 13311.

[0290] Figure 43 shows a cross-sectional structure of a wind wheel 11 and an air duct assembly 132 (only the first air duct component 1321 is shown) provided in an embodiment of the present application. Taking the wind wheel 11 shown in Figure 43 as an example, the vortex direction of the blades 115 of the wind wheel 11 is right-handed, corresponding to the clockwise direction. In this case, the guide surfaces 13311 of the multiple guide members 1331 are arranged in a counterclockwise direction. When the airflow generated by the wind wheel 11 enters the air duct space 1323, it will flow in a counterclockwise direction under the guidance of the guide surfaces 13311, thereby achieving the guiding effect of the guide assembly 133 on the airflow within the air duct space 1323.

[0291] It should be noted that in this embodiment, for the wind wheel 11 with right-handed blades 115, the wind wheel 11 is generally driven to rotate counterclockwise, that is, the rotation direction of the wind wheel 11 is opposite to the swirl direction of the blades 115. Accordingly, driven by the wind wheel 11, the direction of the airflow blown out is also counterclockwise, and the multiple guide surfaces 13311, which are also arranged counterclockwise, further guide the airflow in the counterclockwise direction and flow toward the outlet of the air duct space 1323, thereby ensuring that the airflow blown out of the air duct space 1323 is annular. For the impeller 11 with left-hand rotating blades 115, the impeller 11 is usually driven to rotate in a clockwise direction. Accordingly, the airflow blown out of the impeller 11 flows in a clockwise direction. The multiple guide surfaces 13311 arranged in a clockwise direction further guide the airflow in a clockwise direction toward the outlet of the air duct space 1323, thereby ensuring that the airflow blown out of the air duct space 1323 is an annular airflow. The annular airflow can act relatively gently on the surface of the human skin, and is unlikely to cause physical discomfort even after prolonged use, thereby improving the user comfort of the fan mechanism 1.

[0292] In some embodiments of the present application, as shown in Figure 44, the air duct assembly 132 includes a first air duct component 1321 and a second air duct component 1322; the first air duct component 1321 and the second air duct component 1322 are both arranged around the air outlet 112 of the wind wheel 11, wherein the first air duct component 1321 is adjacent to the top of the wind wheel 11, and the second air duct component 1322 is adjacent to the bottom of the wind wheel 11, and the air duct space 1323 is formed between the first air duct component 1321 and the second air duct component 1322; the first air duct component 1321 and the second air duct component 1322 are each close to each other at one end away from the wind wheel 11 and there is a gap between the two to form an annular opening 1324, which can be used as an air outlet of a bladeless fan lamp to discharge the airflow blown out by the wind wheel 11.

[0293] In the embodiment of the present application, the air inlet 111 is generally located at the top of the wind rotor 11, while the air outlet 112 is located on the side of the wind rotor 11 and is opened in a circumferential direction. The first air duct component 1321 and the second air duct component 1322 are both arranged in a circle on the side of the wind rotor 11, wherein the first air duct component 1321 is adjacent to the top of the wind rotor 11, and the second air duct component 1322 is adjacent to the bottom of the wind rotor 11, thereby forming an annular air duct space 1323 between the first air duct component 1321 and the second air duct component 1322. The inlet of the air duct space 1323 is directly connected to the air outlet 112 of the wind rotor 11 to ensure that the airflow blown out by the wind rotor 11 enters the air duct space 1323 to the greatest extent. The bottom and top of the wind rotor 11 are arranged opposite each other.

[0294] As shown in Figures 42 and 44, the wind rotor 11 includes a top plate 114 and a bottom plate 113, with blades 115 fixed between the top plate 114 and the bottom plate 113. The first air duct member 1321 is at least partially covered on a side of the top plate 114 away from the bottom plate 113, and is bent at a first circumferential edge 1141 of the top plate 114 toward the second air duct member 1322 to form a bent portion 13212. The bent portion 13212 includes a vertical bent surface 132121, which is at least partially located on the outside of the top plate 114. The first circumferential edge 1141 is the edge of the top plate 114 away from the rotation axis of the wind rotor 11. It is understood that the vertical curved surface 132121 has the smallest angle with the rotation axis of the wind rotor 11 compared to its two adjacent portions in the radial direction of the wind rotor 11, and thus the vertical curved surface 132121 tends to extend along the height direction (vertical direction). In some embodiments, the vertical curved surface 132121 can be parallel to the height direction, or can intersect the height direction at a certain angle.

[0295] Exemplarily, the lower end of the vertical bending surface 132121 may be no lower than the bottom end of the top plate 114 , so that the vertical bending surface 132121 does not shield the air outlet 112 of the wind wheel 11 .

[0296] In some embodiments, the duct assembly 132 is spaced apart from the rotor 11 so that the duct assembly 132 can remain stationary when the rotor 11 rotates. The air guide 1331 is disposed in the duct space 1323 enclosed by the first duct member 1321 and the second duct member 1322. The edge of the air guide 1331 close to the rotation axis of the rotor 11 does not exceed the edges of the first duct member 1321 and the second duct member 1322 close to the rotation axis of the rotor 11. The blades 115 are disposed between the top plate 114 and the bottom plate 113. The edges of the blades 115 away from the rotation axis of the rotor 11 do not exceed the edges of the top plate 114 and the bottom plate 113 away from the rotation axis of the rotor 11, so as to avoid interference with the duct assembly 132 when the rotor 11 rotates.

[0297] As shown in Figures 42 and 44, the vertical bending surface 132121 is spaced from the first circumferential edge 1141 of the top plate 114, and the radial distance between the vertical bending surface 132121 and the first circumferential edge 1141 is smaller than the radial distance between the guide member 1331 and the first circumferential edge 1141.

[0298] In the height direction from the bottom plate 113 to the top plate 114, the second air duct member 1322 is no higher than the bottom plate 113. This ensures that the second air duct member 1322 does not obstruct the air outlet 112 of the wind rotor 11. In other words, in the height direction, the size of the entrance to the air duct space 1323 can be larger than or substantially equal to the size of the air outlet 112 of the wind rotor 11. This ensures that the entrance to the air duct space 1323 is directly connected to the air outlet 112 of the wind rotor 11, allowing the airflow from the air outlet 112 to enter the air duct space 1323 to the greatest extent possible.

[0299] In some embodiments, as shown in Figures 42 and 44, the second air duct component 1322 is spaced from the second circumferential edge 1134 of the base plate 113, and the radial distance between the second air duct component 1322 and the second circumferential edge 1134 is smaller than the distance between the guide member 1331 and the second circumferential edge 1134, wherein the second circumferential edge 1134 is the edge of the base plate 113 on the side away from the rotation axis of the wind wheel 11.

[0300] It can be understood that the guide member 1331 may be arranged to be tilted relative to the circumference of the wind wheel 11, resulting in different radial distances from different positions on the guide member 1331 to the rotation axis of the wind wheel 11, and thus different radial distances from different positions on the guide member 1331 to the first circumferential edge 1141 or the second circumferential edge 1134. In an embodiment of the present application, the radial distance between the guide member 1331 and the first circumferential edge 1141 can be determined as the radial distance between the position on the guide member 1331 closest to the rotation axis of the wind wheel 11 and the first circumferential edge 1141, that is, the minimum radial distance between the guide member 1331 and the first circumferential edge 1141 of the top plate 114; the radial distance between the guide member 1331 and the second circumferential edge 1134 can be determined as the radial distance between the position on the guide member 1331 closest to the rotation axis of the wind wheel 11 and the first circumferential edge 1141, that is, the minimum radial distance between the guide member 1331 and the first circumferential edge 1141 of the top plate 114.

[0301] 42 and 43 , a first circumferential edge 1141 of the top plate 114 and a second circumferential edge 1134 of the bottom plate 113 are substantially flush in the radial direction of the wind rotor 11. A trailing edge 1152 of the blade 115 on a side away from the rotation axis may be flush with the first circumferential edge 1141 of the top plate 114 and the second circumferential edge 1134 of the bottom plate 113, respectively.

[0302] When the wind wheel 11 is running, it sucks in air from the air inlet 111 at the top and forms an airflow. After the airflow passes through the blades 115, it is blown out at the air outlet 112 and enters the air duct space 1323. Then, under the action of the guide component 133, an annular airflow is formed and blown out of the air duct space 1323.

[0303] As shown in Figure 44, the further away from the rotor 11 the first and second duct members 1321 and 1322 are, the closer they are to each other. Therefore, the smaller the cross-sectional area of ​​the resulting duct space 1323 becomes as it moves radially away from the rotor 11. This helps concentrate the airflow from the rotor 11 and improves the air delivery efficiency and air delivery distance at the outlet of the duct space 1323. The outlet of the duct space 1323 is defined by the end of the first duct member 1321 away from the rotor 11 and the end of the second duct member 1322 away from the rotor 11.

[0304] In some embodiments of the present application, as shown in FIG45 , the air guide 1331 is connected to the first air duct member 1321 and is arranged obliquely relative to the inner wall of the first air duct member 1321. The air guide surface 13311 is the surface of the air guide 1331 facing away from the first air duct member 1321. The direction from the first end to the second end of the air guide surface 13311 is parallel to the tangent direction of the arrangement direction of the plurality of air guide surfaces 13311. The first end is the end away from the first air duct member 1321, and the second end is the end connected to the first air duct member 1321.

[0305] 43 and 45 , each guide member 1331 is obliquely connected to the inner wall of the first duct member 1321. Thus, the guide member 1331 has a surface facing the inner wall of the first duct member 1321, and a guide surface 13311 facing away from the inner wall of the first duct member 1321. When the airflow from the wind wheel 11 strikes the guide surface 13311, the airflow flows along the guide surface 13311 from the first end to the second end, with the first end and the second end facing each other. Furthermore, the airflow is pressurized by the guide member 1331, thereby reducing the degree of airflow divergence and concentrating the airflow. Therefore, the guide member 1331 can guide and converge the diverging airflow from the wind wheel 11, further increasing the airflow volume and distance at the outlet of the duct space 1323.

[0306] 44 , the air guide 1331 abuts against the second air duct member 1322. For example, the top of the air guide 1331 is connected to the first air duct member 1321, and a side adjacent to the top is also connected to the first air duct member 1321, and the bottom of the air guide 1331 abuts against the second air duct member 1322.

[0307] Optionally, the tangent angle of each air guide 1331 on the first air duct component 1321 is greater than degrees and less than degrees. The tangent angle refers to the angle between the tangent of the first air duct component 1321 at the contact point and the air guide 1331 (or the tangent of the air guide 1331 at the contact point) on the set plane, wherein the set plane is perpendicular to the rotation axis of the wind wheel 11, and the contact point is the intersection of the first air duct component 1321 and the air guide 1331 on the set plane. As shown in Figure 46, the tangent angle of the air guide 1331 on the first air duct component 1321 can be expressed by θ, 15°<θ<90°. Exemplarily, the tangent angle θ can be 30°, 40°, 50° or 60°.

[0308] Optionally, the guide surface 13311 of at least one guide member 1331 is a curved surface, and the curved surface is bent in a direction away from the first air duct component 1321 .

[0309] As shown in FIG46 , at least one of the plurality of guide members 1331 is a curved plate member, and thus the guide surface 13311 of the guide member 1331 can be a curved surface, and the airflow is suitable for flowing through the convex side of the curved surface. Optionally, the guide surface 13311 is in an arc shape.

[0310] In some embodiments of the present application, at least one of the multiple guide members 1331 is provided with a first connecting structure 13315; a second connecting structure 13221 is provided at a position corresponding to the first connecting structure 13315 on the second air duct component 1322, and the second connecting structure 13221 is connected to or cooperates with the first connecting structure 13315.

[0311] In one example, the first connection structure 13315 and the second connection structure 13221 are connected to each other. The first connection structure 13315 and the second connection structure 13221 can be one of a hook and the other of a slot, respectively. During assembly, the hook is inserted into the corresponding slot, thereby connecting the first air duct component 1321 and the second air duct component 1322 together.

[0312] In another example, as shown in FIG47 , a first connecting structure 13315 and a second connecting structure 13221 cooperate. The first connecting structure 13315 is a screw hole extending vertically through the first air duct component 1321 and the air guide 1331. The second connecting structure 13221 is a screw hole provided on the second air duct component 1322. The first and second air duct components 1321, 1322 are connected together by a fourth fastener 134 installed in the first and second connecting structures 13315, 13221. The fourth fastener 134 may be, for example, a screw. The air guide 1331 provided with the first connecting structure 13315 is thicker than the other air guides 1331 to ensure the strength of the first connecting structure 13315.

[0313] FIG48 shows a bottom view of the matching structure of the wind rotor 11 and the first air duct component 1321 in an embodiment of the present application. In this figure, the darker (black) solid lines are used to represent the structural features of the wind rotor 11 exposed to the outside view, and the lighter (gray) solid lines are used to represent the blades 115 hidden inside the wind rotor 11. In addition, in FIG48, L is used to represent the distance between the guide member 1331 and the blade 115, for example, the minimum distance between the guide member 1331 and the outer edge of the blade 115; D is used to represent the width of the air duct space 1323, that is, the minimum distance between the end of the guide member 1331 connected to the first air duct component 1321 and the outer edge of the blade 115. In the embodiment of the present application, the above distance can be a radial distance in the radial direction of the wind rotor 11.

[0314] In this embodiment of the present application, the distance L between the air guide 1331 and the blades 115 of the wind rotor 11 can be determined based on the diameter of the wind rotor 11 and the size of the air duct outlet (annular opening 1324). When the distance L between the air guide 1331 and the blades 115 of the wind rotor 11 is too large, the air guidance effect is poor. When the distance L between the air guide 1331 and the blades 115 of the wind rotor 11 is too small, the air output volume decreases and the air outlet distance is shortened, thereby affecting the air outlet effect. Optionally, the distance L between the air guide 1331 and the blades 115 of the wind rotor 11 is 0.3 to 0.7 times the width D of the air duct space 1323. Furthermore, the distance L between the air guide 1331 and the blades 115 of the wind rotor 11 is 0.5 to 0.6 times the width D of the air duct space 1323. For example, it can be 0.57 times. Testing has shown that at this ratio, the fan mechanism 1 achieves both good air guidance and air outlet effects.

[0315] In some embodiments of the present application, the number of the flow guides 1331 is greater than or equal to the number of the blades 115 of the wind wheel 11 .

[0316] Within a certain range, the more the number of flow guides 1331, the more evenly the airflow flowing out of the blades 115 is divided, and the better the flow guiding effect. However, when the number of flow guides 1331 is too large, it is easy to cause the airflow in the air duct space 1323 to be blocked, thereby causing the air volume to decrease, the air flow velocity to decrease, and the air outlet distance to decrease, affecting the air outlet effect. Optionally, the number of flow guides 1331 can be 1.1 times to 3 times the number of blades 115. Further, the number of flow guides 1331 can be 1.5 times to 2 times the number of blades 115. For example, the ratio of the number of flow guides 1331 to the number of blades 115 can be 5:3. Tests show that at this ratio, the fan mechanism 1 has both good flow guiding effect and air outlet effect.

[0317] To sum up, the fan mechanism 1 provided in the embodiment of the present application has an air duct space 1323 surrounded by a first air duct component 1321 and a second air duct component 1322, and the air duct space 1323 surrounds the outside of the air outlet 112 of the wind wheel 11; a plurality of air guide members 1331 are arranged in the air duct space 1323, and the number of the plurality of air guide members 1331 is not less than the number of blades 115 of the wind wheel 11, and each air guide member 1331 is obliquely connected to the inner wall of the first air duct component 1321, and the distance between the air guide member 1331 and the blade 115 is 0.3 to 0.7 times the width of the air duct space 1323. The guide member 1331 has a guide surface 13311. The multiple guide surfaces 13311 cooperate to direct the flow direction of the airflow blown out by the impeller 11. The guide direction is opposite to the vortex direction of the blades 115 of the impeller 11. As a result, the airflow is guided by the guide surfaces 13311 within the air duct space 1323 to form an annular airflow that flows in the opposite direction to the vortex direction of the blades 115 and is then blown out. Because the annular airflow has a gentler effect on the human skin, the fan mechanism 1 provided in this embodiment of the present application provides greater user comfort and health when in use, compared to fans with direct airflow in related arts.

[0318] The present application also provides a heat dissipation device, which may include the annular air outlet fan mechanism 1 described in any of the above embodiments. For example, the heat dissipation device may be a bladeless electric fan, a bladeless fan lamp, or the like.

[0319] Optionally, the heat dissipation device further includes a shell having an air outlet opening (for example, the air inlet 1311 mentioned above), the fan mechanism 1 is located inside the shell, and the outlet of the air duct space 1323 of the fan mechanism 1 is correspondingly connected to the air outlet opening.

[0320] Since the heat dissipation device provided by the embodiment of the present application adopts the above-mentioned annular air outlet fan mechanism 1, the air duct assembly 132 can form an air duct space 1323 in the annular direction of the wind wheel 11. The air duct space 1323 is connected to the air outlet 112 of the wind wheel 11, so that the airflow generated by the rotation of the wind wheel 11 flows out from the air outlet 112, flows through the air duct space 1323 and is then blown out; wherein, since the air duct space 1323 is provided with a guide assembly 133, the guide direction of the guide assembly 133 is opposite to the vortex direction of the blade 115, and can guide the airflow in the air duct space 1323 to flow in an annular direction, the airflow blown out from the air duct space 1323 is an annular airflow, and the blowing effect on the skin on the surface of the human body is softer. Therefore, when the heat dissipation device provided by the embodiment of the present application is used, compared with the fan with direct airflow in the related art, it brings better physical comfort to the user and protects the user's health.

[0321] In the above embodiment, the blade 115 may be a spiral blade 115 and the flow guide 1331 may be a single plate-shaped member. In other embodiments, the blade 115 may also be a single plate-shaped member and the flow guide 1331 may be a convex hull structure having at least two intersecting planes.

[0322] As shown in Figure 49 , an embodiment of the present disclosure provides a fan mechanism 1 that can be mounted on a ceiling in a suspended manner, and thus can also be referred to as a ceiling fan. This fan mechanism 1 can be used in a bladeless fan lamp. As shown in Figures 53 and 54 , the fan mechanism 1 includes an air duct assembly 132 (which can serve as a housing for a wind wheel), a wind wheel 11, and a plurality of air guides 1331.

[0323] As shown in Figures 50 and 51 , the top of the duct assembly 132 has an air inlet gap 13211 and the bottom has an annular opening 1324. The impeller 11 is located within the duct assembly 132, for example, within the space enclosed by the side of the second duct component 1322 away from the first duct component 1321. Therefore, the duct component can also be referred to as a shell, and it cooperates with the outer shell 131 to form the fan housing 13. The first duct component 1321 located on the outside can be referred to as the outer shell, and the second duct shell located on the inside can be referred to as the inner shell.

[0324] The air guide 1331 surrounds the wind wheel 11. The air guide 1331 has a first air guide portion 13312, the distal end of which is connected to the air duct assembly 132 (e.g., the first air duct component 1321). Within a reference plane perpendicular to the rotation axis of the wind wheel 11, the line connecting the head end of the first air guide portion 13312 and the central axis of the annular opening 1324 is defined as a first reference line a, and the line connecting the distal end of the first air guide portion 13312 and the rotation axis is defined as a second reference line c. The second reference line c and the first reference line a are arranged circumferentially in sequence along the rotation direction of the wind wheel 11. The first air guide portion 13312 is arc-shaped, with the concave surface of the first air guide portion 13312 facing away from the wind wheel 11.

[0325] Because the annular opening 1324 on the air duct assembly 132 is formed around the rotation axis of the wind rotor 11, the central axis of the annular opening 1324 can be aligned with the rotation axis of the wind rotor 11, so that the aforementioned reference plane is perpendicular to the central axis of the annular opening 1324. It is understood that the rotation direction of the wind rotor 11 is not limited to clockwise or counterclockwise, and can actually indicate the circumferential direction (annular direction) of the wind rotor 11. Therefore, based on Figure 52, it can be seen that the second reference line c and the first reference line a are arranged in sequence along the circumference of the wind rotor 11.

[0326] The annular opening 1324 is divided by the air guide 1331 into a plurality of annularly arranged air outlet gaps 13241. If the air guide 1331 (also referred to as the air guide) includes only the first air guide portion 13312, the first air guide portion 13312 divides the annular opening 1324 into a plurality of continuously arranged air outlets 112. If the air guide 1331 includes only the first air guide portion 13312, the side surface of the first air guide portion 13312 facing away from the first air duct housing can serve as the air guide surface 13311 in the above embodiment.

[0327] The fan mechanism (bladeless fan light) provided by the embodiment of the present disclosure is shown in Figure 52. The second reference line c and the first reference line a are arranged along the rotation direction of the wind wheel 11, which can make the deflection direction of the first guide part along the rotation direction of the wind wheel 11, so that the deflection direction of the first guide part is close to the direction of the airflow flowing out of the wind wheel 11, which can avoid the airflow and the first guide part from colliding violently, thereby reducing the noise generated by the airflow.

[0328] First air guide 13312 is curved. Compared to a straight first air guide 13312, a curved first air guide 13312 increases its length, thereby increasing the airflow's pressurization path and facilitating increased wind pressure. Since second air guide 13313 is longer, increasing the length of first air guide 13312 reduces the pressure difference between the ends of second air guide 13313 and first air guide 13312, thereby making the airflow from annular opening 1324 more uniform. Furthermore, first air guide 13312 deflects the wind flow radially toward rotor 11, resulting in a larger radial component of the airflow after it reaches annular opening 1324, facilitating airflow over a greater distance.

[0329] In some examples, as shown in FIG54 , the wind rotor 11 includes a plurality of blades 115, which are arranged in a ring and surround the air inlet 111 (or the air inlet gap 13211 of the air duct assembly 132) on the fan. In a reference plane perpendicular to the rotation axis of the wind rotor 11, a line connecting the tip of the blade 115 and the central axis of the wind rotor 11 is defined as a third reference line m, a line passing through the tip of the blade 115 and perpendicular to the third reference line m is defined as a fourth reference line n, an obtuse angle formed between the fourth reference line n and the line connecting the leading and trailing ends of the blade 115 is defined as λ1, a line connecting the leading end of the first air guide 13312 and the rotation axis (central axis) of the wind rotor 11 is defined as a fifth reference line p, a line connecting the leading end of the first air guide 13312 and perpendicular to the fifth reference line p is defined as a sixth reference line q, and an acute angle formed between the sixth reference line q and a tangent line at the leading end of the first air guide 13312 is defined as λ2. Therefore, λ1-90°≤λ2≤λ1-80°.

[0330] When the air flow passes through the wind wheel 11, it has component velocities in the first direction and the second direction, where the first direction is the direction of the third reference line m, and the second direction is the direction of the line connecting the head end and the tail end of the blade 115, so the absolute speed of the air flow is between the first direction and the second direction.

[0331] By setting λ1-90°≤λ2≤λ1-80°, the direction of the tangent line at the head end of the first air guide portion 13312 can be positioned between the first direction and the second direction, thereby making the airflow as parallel as possible to the head end of the first air guide portion 13312. This can reduce the impact of the airflow on the first air guide portion 13312, thereby reducing the noise generated by the airflow.

[0332] In some examples, as shown in Figure 54, the line between the end of the first wind guide portion 13312 and the rotation axis of the wind wheel 11 is assumed to be the seventh reference line e, the straight line passing through the end of the first wind guide portion 13312 and perpendicular to the seventh reference line e is assumed to be the eighth reference line f, and the acute angle formed between the eighth reference line f and the tangent of the end of the first wind guide portion 13312 is λ3, then λ2+20°≤λ3≤λ2+40°.

[0333] In this way, the end of the first air guide portion 13312 can be made as close as possible to the radial direction of the wind wheel 11, so that the airflow is deflected along the radial direction of the wind wheel 11 when it flows out from the end of the first air guide portion 13312. This makes the airflow more concentrated, can reduce airflow losses, and is conducive to the airflow blowing to a farther distance. The farther the distance the wind blows, the easier it is for the wind blown out of each air outlet gap 13241 to be continuous in the circumferential direction, thereby improving the effect of uniform annular air outlet of the ceiling fan (bladeless fan light). If the difference between λ3 and λ2 is too large, it may cause the deflection direction of the end of the first air guide portion 13312 to be opposite to the deflection direction of the head end of the first air guide portion 13312, causing the first air guide portion 13312 to deviate from the radial direction of the wind wheel 11.

[0334] In some examples, as shown in FIG53 , the leading edge 1151 of the blade 115 has a convex structure 11511, which is located between the top and bottom of the leading edge 1151. The convex structure 11511 protrudes in a direction close to the air inlet 111 (or the air inlet gap 13211). The leading edge 1151 is the edge of the blade 115 close to the air inlet 111. Assuming that the distance between the top of the leading edge 1151 and the rotation axis of the wind wheel 11 is R1, the distance between the bottom of the leading edge 1151 and the rotation axis is R2, and the distance between the convex structure 11511 and the rotation axis is R3, then R1>R3, and R2>R3. The height of the top of the leading end of the first air guide 13312 is lower than the height of the convex structure 11511.

[0335] As can be seen from FIG. 53, the leading edge 1151 in the blade 115 is the edge of the blade 115 close to the axis of rotation of the wind turbine 11; the trailing edge 1152 is the edge of the blade 115 away from the axis of rotation of the wind turbine 11.

[0336] Among them, according to the bionics principle, the convex structure 11511 can imitate the convex structure of the leading edge of a bird's wing to reduce the eddy current at the leading edge 1151 of the blade 115, making the air flow more stable, so that the air resistance received by the leading edge 1151 of the blade 115 is smaller, and thus reducing the wind noise at the leading edge 1151.

[0337] If the top of the head end of the first air guiding part 13312 is higher than the convex structure 11511, it will cause the overall height of the first air guiding part 13312 to be higher, resulting in a larger thickness of the ceiling fan, and thus a larger volume and weight of the ceiling fan.

[0338] In some examples, as shown in FIG. 53, the air duct assembly 132 as the housing includes a first air duct member 1321 (which can also be called the outer shell) and a second air duct member 1322 (which can also be called the inner shell). The first air duct member 1321 surrounds the second air duct member 1322. The second air duct member 1322 has an air inlet gap 13211, and an annular opening 1324 is formed between the bottom of the first air duct member 1321 and the bottom of the first air duct member 1321. The top of the head end of the first air guiding part 13312 is connected to the first air duct member 1321, and the bottom of the head end of the first air guiding part 13312 is connected to the second air duct member 1322. Among them, the bottom of the head end of the first air guiding part 13312 is located below the bottom of the wind turbine 11. If the bottom of the head end of the first air guiding part 13312 is located above the bottom of the wind turbine 11, the position where the second air duct member 1322 and the bottom of the head end of the first air guiding part 13312 are connected will also be located above the bottom of the wind turbine 11, thus blocking the air outlet of the wind turbine 11.

[0339] In some examples, as shown in FIG. 53, let the height of the trailing edge 1152b of the blade 115 be H1, and the height difference between the top of the head end of the first air guiding part 13312 and the convex structure 11511 be H2, then H2 ≤ 0.2H1, where the trailing edge 1152b is opposite to the leading edge 1151a. From simulation and test data, when 0 < H2 ≤ 0.2H1, the air guiding effect of the first air guiding part 13312 is the best and the generated noise is the smallest. If H2 is too large, it will cause the height of the first air guiding part 13312 to be too low, so that after the air flow flows out of the blade 115, it cannot be quickly guided by the first air guiding part 13312, but is prone to directly collide with the air duct assembly 132, resulting in a large noise generated by the air flow.

[0340] In some examples, the height of the bottom of the first end of the first air guide 13312 is higher than the height of the bottom of the rear end of the first air guide 13312. And / or, the height of the bottom of the first end of the first air guide 13312 is lower than the height of the wind wheel 11 at the rotation axis. This can form a downward air duct in the housing. After the airflow passes through the convex structure 11511, the main air intake portion is directed to the first air guide 13312 below, and then flows to the annular opening 1324. This allows the flow direction of the airflow to change slowly, avoiding the airflow suddenly changing direction at the annular opening 1324 and generating large noise.

[0341] In some examples, along the direction from the air inlet 111 to the annular opening 1324 (that is, from top to bottom in the height direction), the distance between the head end of the first air guide 13312 and the rotation axis of the wind wheel 11 (or the central axis of the annular opening 1324) gradually increases or gradually decreases. In this way, the airflow can be prevented from colliding with various positions of the head end of the first air guide 13312 at the same time. For example, along the direction from the air inlet 111 to the annular opening 1324, the distance between the head end of the first air guide 13312 and the central axis of the annular opening 1324 gradually increases, so that the top of the head end of the first air guide 13312 is closest to the blade 115. Therefore, after the airflow flows out from the blade 115, it first collides with the top of the head end of the first air guide 13312 and then collides with the bottom, thereby reducing the collision intensity of the airflow with the first air guide 13312, thereby reducing the noise generated by the airflow.

[0342] In some examples, as shown in Figure 53, assuming that the distance between the top of the head end of the first wind guide portion 13312 and the rotation axis of the wind wheel 11 is L1, the distance between the bottom of the head end of the first wind guide portion 13312 and the rotation axis is L2, and the maximum radius of the wind wheel 11 is R, then L2>L1, 0.05L2-R≤L2-L1≤0.2L2-R.

[0343] The air duct assembly 132 includes a first air duct component 1321 and a second air duct component 1322. The first air duct component 1321 is surrounded by the second air duct component 1322. The first air duct component 1321 has an air inlet 111. An annular opening 1324 is formed between the bottom of the first air duct component 1321 and the bottom of the second air duct component 1322. Along the direction of the air inlet 111 pointing to the annular opening 1324, the distance between the first air duct component 1321 and the central axis of the annular opening 1324 gradually increases, and the distance between the head end of the first air guide portion 13312 and the central axis of the annular opening 1324 gradually increases.

[0344] Since the distance between the first air duct member 1321 and the central axis of the annular opening 1324 gradually increases along the direction from the air inlet 111 to the annular opening 1324, if L2 is less than L1, the distance between the first end of the bottom of the first air guide 13312 and the first air duct member 1321 will be too large, resulting in a longer air guide path at the bottom of the first air guide 13312, thereby increasing the air pressure path. This will result in a higher wind pressure at the end of the bottom of the first air guide 13312, resulting in a higher noise generated by the airflow.

[0345] For the condition 0.05L2-R≤L2-L1≤0.2L2-R, if L2-L1 is too large, the distance between the top of the leading end of the first air guide 13312 and the trailing edge 1152 of the blade 115 will be too close, resulting in a higher velocity when the airflow reaches the top of the leading end of the first air guide 13312, and thus a stronger collision with the first air guide 13312, causing louder noise. If L2-L1 is too small, the distance between the bottom of the leading end of the first air guide 13312 and the trailing edge 1152 of the blade 115 will be too far, resulting in a lower velocity when the airflow reaches the bottom of the leading end of the first air guide 13312, and thus a shorter air delivery distance for the ceiling fan.

[0346] In some examples, as shown in FIG55 , within a reference plane, the angle between the tangent line at the end of the first air guide 13312 and the line connecting the end of the first air guide 13312 and the axis of rotation of the wind wheel 11 (or the central axis of the annular opening 1324) is ε, and 0°<ε<20°. This allows the angle between the wind direction at the end of the first air guide 13312 and the radial direction of the annular opening 1324 to be smaller, allowing the first air guide 13312 to deflect the air outlet direction toward the radial direction of the ceiling fan, thereby increasing the radial air supply distance of the ceiling fan.

[0347] As shown in Figures 49 to 52, the ceiling fan (bladeless fan light) includes a duct assembly 132, a rotor 11, and multiple air guides 1331. The rotor 11 has an air inlet 111, the duct assembly 132 has an air inlet gap 13211, and the bottom of the duct assembly 132 has an annular opening 1324. The rotor 11 is located inside the duct assembly 132. Multiple air guides 1331 surround the rotor 11 and divide the annular opening 1324 into multiple air outlet gaps 13241. The air guide 1331 has a second air guide portion 13313 and a first air guide portion 13312. The second air guide portion 13313 faces the wind wheel 11. The head end of the second air guide portion 13313 is connected to the head end of the first air guide portion 13312. There is an air outlet gap 13241 between the first air guide portion 13312 of one air guide 1331 and the second air guide portion 13313 of an adjacent air guide 1331.

[0348] As shown in Figure 52, in a reference plane perpendicular to the rotation axis (the central axis of the annular opening 1324), the line between the head end of the second air guide portion 13313 or the head end of the first air guide portion 13312 and the rotation axis (the central axis of the annular opening 1324) is set as the first reference line a, and the end of the second air guide portion 13313 and the rotation axis (the line between the central axis of the annular opening 1324) is set as the ninth reference line b, then the second reference line c is located between the first reference line a and the ninth reference line b.

[0349] The axis of the annular opening 1324 , the axis of the wind wheel 11 (rotation axis), and the axis of the entire ceiling fan are collinear. The length of the second air guide portion 13313 is greater than the length of the first air guide portion 13312 .

[0350] As shown in Figure 56, the fan mechanism 1 also includes a motor 12, which is fixed below the air duct assembly 132. The wind wheel 11 and the motor 12 are connected by transmission. The wind wheel 11 is opposite to the air inlet gap 13211 of the air duct shell. The wind wheel 11 can be a centrifugal fan or a diagonal flow fan.

[0351] When the air guide member 1331 includes a first air guide portion 13312 and a second air guide portion 13313 , the first air guide portion 13312 may be arc-shaped, straight-shaped, or have other shapes.

[0352] In the ceiling fan provided by the embodiment of the present disclosure, the angle occupied by the second air guide portion 13313 of the air guide 1331 is the angle between the first reference line a and the ninth reference line b, and the angle occupied by the portion shielded by the air guide 1331 is the angle between the second reference line c and the ninth reference line b. Since the second reference line c is located between the first reference line a and the ninth reference line b, the angle occupied by the second air guide portion 13313 is greater than the angle occupied by the portion shielded by the air guide 1331.

[0353] In this way, the guide member 1331 has a sufficiently long second air guide portion 13313, while also shortening the portion shielded by the guide member 1331. This allows the ceiling fan to deliver air over a long distance, while also ensuring that the air blown out from each air outlet 112 is continuous in the circumferential direction, resulting in a more uniform annular air flow from the ceiling fan. Furthermore, this design also allows the first air guide portion 13312 to be longer, providing a good air guiding effect.

[0354] In some examples, as shown in FIG52 , assuming that the angle between the ninth reference line b and the second reference line c is α, then 20°<α<30°.

[0355] As shown in Figure 57, the horizontal axis in the figure represents α, the unit is °, and the vertical axis represents the wind sensation radius, that is, the blowing radius that the user can feel when using the ceiling fan provided by the embodiment of the present disclosure, the unit is m.

[0356] As can be seen in Figure 57, as α increases, the wind-sensing radius also gradually increases. Since the wind-sensing radius is smaller when 0° < α < 20°, α > 20° can be used. When α > 30°, although the wind-sensing radius continues to increase, the guide member 3 will block too much of the annular opening 12, making the air outlet gap 120 too small, resulting in uneven airflow from the ceiling fan. Therefore, in some examples, 20° < α < 30° is used.

[0357] In some examples, as shown in FIG52 , assuming the number of guides 1331 is z, 130° / α<z<150° / α. That is, the angle of the portion shielded by the plurality of guides 1331 is at least 130° and at most 150°.

[0358] Experimental measurements have shown that if z < 130° / α, i.e., zα < 130°, the angle covered by the shielding elements of the multiple air guides 1331 is too small, resulting in a larger air outlet area for each air outlet gap 13241. This makes it difficult for the air outlet gaps 13241 to effectively increase wind pressure and force. Furthermore, this shortens the length of the second air guide 13313 and the first air guide 13312, reducing the pressure-boosting path for the airflow in the second and first air guides 13313 and 13312, hindering the increase in air pressure at the air outlet gaps 13241.

[0359] If z>150° / α, i.e., zα>150°, the shielded area of ​​the multiple air guides 1331 will occupy a larger area, resulting in an excessively small air outlet gap 13241. Although this will increase the air pressure at the air outlet gap 13241, since the air guide 1331 does not release air, the air blown out of the multiple air outlet gaps 13241 will not be continuous in the circumferential direction, resulting in uneven annular air supply from the ceiling fan. Furthermore, if the air outlet gap 13241 is too small, the wind speed at the air outlet gap 13241 will be too high, resulting in excessive wind noise. Furthermore, if the shielded area of ​​the multiple air guides 1331 is too large, the collision area between the airflow and the air guide 1331 will increase, thereby increasing the collision intensity between the airflow and the air guide 1331 and causing increased wind noise.

[0360] In some examples, as shown in FIG52 , 4 ≤ z ≤ 6. For example, z = 6. If the number z of air guides 1331 is too small, the air outlet gap 13241 will be too large, resulting in too low a wind speed at the air outlet gap 13241, which is not conducive to increasing the air supply distance of the air outlet gap 13241. If the number z of air guides 1331 is too large, on the one hand, it will increase the frequency of collisions between the airflow and the air guides 1331, but the collision intensity of the airflow and the air guides 1331 will be too high, thereby generating relatively loud noise. On the other hand, it will cause the air outlet gap 13241 to be too small, resulting in too high a wind speed at the air outlet gap 13241, which will lead to relatively loud wind noise.

[0361] In some examples, as shown in FIG52 , within the reference plane, the angle between the first reference line a and the second reference line c is γ, and 0°<γ<15°.

[0362] If γ is too large, the angle between the second air guide portion 13313 and the first air guide portion 13312 will be too small, making it difficult to machine the air guide 1331. Furthermore, the air outlet gap 13241 will be too large, resulting in too low a wind speed and pressure at the air outlet gap 13241, which is not conducive to increasing the air supply distance of the air outlet gap 13241. If γ is too small, on the one hand, the air outlet gap 13241 will be too small, resulting in too high a wind speed at the air outlet gap 13241, which will generate a lot of noise. On the other hand, the spacing between adjacent air outlet gaps 13241 will be too large, which will prevent the aforementioned effect of more uniform annular air outlet.

[0363] The above technical solution enables the wind blown out of each air outlet gap 13241 to be continuous in the circumferential direction, thereby achieving a relatively uniform annular air outlet of the ceiling fan. In addition, the uniformity of the wind blown out of each air outlet gap 13241 also affects the uniformity of the annular air outlet.

[0364] Below, an example is given to illustrate how to improve the uniformity of air blowing through each air outlet gap 13241.

[0365] In some examples, as shown in FIG52 , within a reference plane, an angle δ is defined at a connection between the second air guide portion 13313 and the first air guide portion 13312 , and δ is an acute angle.

[0366] As shown in FIG58 , setting δ at an acute angle allows the wind from the wind wheel 11 to blow toward the air guide 1331 so that part of the wind is blown along the second air guide portion 13313 toward the portion of the air outlet gap 13241 near the second air guide portion 13313, while the other part is blown along the first air guide portion 13312 toward the portion of another air outlet gap 13241 near the first air guide portion 13312. In this way, for a single air outlet gap 13241, both the portion near the second air guide portion 13313 and the portion near the first air guide portion 13312 have a larger air volume, thereby making the air output from each air outlet gap 13241 more uniform. Alternatively, it can be described as follows: because there is an air outlet gap 13241 between the first air guide portion 13312 of one air guide member 1331 and the second air guide portion 13313 of the adjacent air guide member 1331, part of the airflow in each air outlet gap 13241 originates from the second air guide portion 13313 of one air guide member 1331, and another part originates from the first air guide portion 13312 of the other air guide member 1331. Therefore, the air blown out from the air outlet gap 13241 is more uniform.

[0367] As shown in Figure 59, when δ is an obtuse angle, on the one hand, without changing the air guiding length of the second air guide part 13313 and the first air guide part 13312, δ being an obtuse angle will make the angle occupied by the part shielded by the guide member 1331 greater than the angle occupied by the second air guide part 13313, resulting in a longer length of the part shielded by the guide member 1331, making the annular air outlet of the ceiling fan uneven.

[0368] On the other hand, this will also cause a greater impact between the airflow from the wind wheel 11 and the first air guide 13312, resulting in greater airflow impact loss and generating greater wind noise. Because there is an air outlet gap 13241 between the second air guide 13313 of the air guide 1331 and the first air guide 13312 of the adjacent air guide 1331, if δ is too large, the airflow near the second air guide 13313 in the air outlet gap 13241 will be greater, resulting in stronger wind, while the airflow near the first air guide 13312 in the air outlet gap 13241 will be less, resulting in uneven airflow at the air outlet gap 13241.

[0369] In some examples, as shown in FIG52 , 9° < δ < 38°. If δ is too small, the connection between the second air guide portion 13313 and the first air guide portion 13312 will not have an effective fillet radius, making the air guide 1331 difficult to manufacture and increasing the complexity and cost of manufacturing the ceiling fan. Furthermore, the connection between the second air guide portion 13313 and the first air guide portion 13312 will not be able to guide the airflow, causing the airflow to quickly escape from the connection between the second air guide portion 13313 and the first air guide portion 13312, resulting in a louder airflow noise.

[0370] In some examples, as shown in FIG55 , the angle between the tangent line of the head end of the second air guide 13313 and the first reference line a is and This reduces the angle between the air blown out by the wind wheel 11 and the second air guide 13313, thereby reducing the impact of the second air guide 13313 on the airflow and further reducing airflow losses. Consequently, the wind force near the second air guide 13313 in the air gap 13241 is brought closer to the wind force near the first air guide 13312, resulting in more uniform air flow out of the air gap 13241. Furthermore, the noise generated when the airflow impacts the second air guide 13313 is reduced.

[0371] In some examples, as shown in Figures 55 and 58, the first air guide portion 13312 is arc-shaped, and the concave surface of the first air guide portion 13312 faces the second air guide portion 13313 of the flow guide member 1331 that is closest to the first air guide portion 13312. Within the reference plane, along the rotation direction of the wind rotor 11, the angle between the tangent of the first air guide portion 13312 and the radial direction of the annular opening 1324 (or the wind rotor 11) gradually decreases.

[0372] On the one hand, compared to a straight first air guide 13312, setting the first air guide 13312 in an arc shape can increase the length of the first air guide 13312, thereby increasing the airflow's pressurization path, which helps increase wind pressure. Because the second air guide 13313 is longer, increasing the length of the first air guide 13312 can reduce the pressure difference between the ends of the second air guide 13313 and the first air guide 13312, thereby making the air discharge from the air gap 13241 more uniform. At the same time, it is also possible to reduce the central angle occupied by the air guide 1331 without reducing the air guide length of the second air guide 13313, even if the central angle occupied by the air gap 13241 is larger. This ensures that the air blown out of the annular opening 1324 has continuity, that is, the air discharge from the annular opening 1324 is more uniform.

[0373] On the other hand, the first wind guide portion 13312 can deflect the direction of the wind toward the radial direction of the wind wheel 11, so that the airflow has a larger radial component after flowing into the air outlet gap 13241, which is conducive to the airflow blowing to a farther distance.

[0374] In some examples, as shown in FIG55 , the distance between the head end of first air guide 13312 and the rotation axis of wind wheel 11 (or the central axis of annular opening 1324) is r1, the maximum radius of wind wheel 11 is R, and r1 / R ≥ 1.05. This provides ample air-guiding space at the head end of second air guide 13313, facilitating the directing of airflow toward outlet gap 13241. Furthermore, this reduces the velocity of the airflow upon reaching the head end of second air guide 13313, thereby reducing the intensity of the airflow's collision with the head end of second air guide 13313 and thereby reducing wind noise.

[0375] If r1 is too small, the gap between the head end of the second wind guide 13313 and the edge of the wind wheel 11 will be small, resulting in a smaller wind-guiding space at the head end of the second wind guide 13313. This makes it difficult for the wind blown by the wind wheel 11 to pass through the guide member 1331, which can easily cause backflow of the airflow. This can also cause the airflow to have an excessively high velocity when it reaches the head end of the second wind guide 13313, resulting in a greater collision intensity between the airflow and the head end of the second wind guide 13313, and thus generate a lot of wind noise.

[0376] In some examples, as shown in Figure 60, it is assumed that the distance between the head end of the second air guide portion 13313 and the central axis of the annular opening 1324 is r1, the maximum radius of the wind wheel 11 is R, and the number of guide members 1331 is z. According to simulation and test data, when (0.1+0.01z)R≤r1-R≤0.4R, the noise generated by the ceiling fan is minimal.

[0377] If r1-R is too large, the airflow path from the impeller 11 to the guide 1331 will be too long. The longer the path, the greater the resistance to the airflow and the greater the energy loss. This will cause the airflow to reach the annular opening 1324 at a too low speed, thus affecting the airflow distance. If r1-R is too small, the distance between the impeller 11 and the guide 1331 will be too close, resulting in a higher flow rate when the airflow reaches the guide 1331, resulting in a stronger collision with the guide 1331 and causing greater noise.

[0378] As can be seen from the above equation, r1-R is positively correlated with z. That is, the greater the number of air guides 1331, the greater the distance between the air guides 1331 and the rotor 11. After exiting the rotor 11, the airflow collides with the air guides 1331. As the number of air guides 1331 increases, the air guides 1331 are densely arranged, resulting in a higher frequency of collisions between the airflow and the air guides 1331, which in turn leads to greater noise generated by the airflow. To reduce airflow noise, as the number z of air guides 1331 increases, r1-R also increases. In other words, the distance between the head end of the second air guide 13313 and the rotor 11 increases. This increases the path of the airflow from the rotor 11 to the head end of the second air guide 13313, thereby increasing the resistance encountered by the airflow and, in turn, reducing the airflow velocity upon reaching the head end of the air guide 1331. This reduction in airflow velocity also reduces wind noise. On the other hand, the lower the airflow velocity, the lower the intensity of the airflow when colliding with the guide member 1331, thereby reducing the noise generated by the collision between the airflow and the guide member 1331. In this way, it can be ensured that the noise generated by the ceiling fan is smaller after the number of guide members 1331 is increased.

[0379] The above equation also shows that r1-R is positively correlated with R. That is, the larger the diameter of the rotor 11, the greater the distance between the guide member 1331 and the rotor 11. As the diameter of the rotor 11 increases, the velocity of the airflow exiting the rotor 11 increases. If the distance between the guide member 1331 and the rotor 11 is smaller, the velocity of the airflow upon reaching the guide member 1331 is higher, resulting in a more intense collision between the airflow and the guide member 1331, which in turn generates greater noise. Therefore, it is necessary to reduce the velocity of the airflow upon reaching the guide member 1331. Aerodynamics show that the longer the path an airflow traverses, the greater the resistance it encounters. Therefore, increasing r1-R can reduce the velocity of the airflow upon reaching the guide member 1331, thereby reducing the intensity of the collision between the airflow and the guide member 1331 and, consequently, the noise generated by the collision between the airflow and the guide member 1331.

[0380] In some examples, as shown in Figures 60 and 61 , the distance between the head end of second air guide 13313 and the rotation axis of wind rotor 11 (or the central axis of annular opening 1324) is r1, the radius of wind rotor 11 is R, and the connection between second air guide 13313 and first air guide 13312 comprises a transition surface 13314, with a radius of r3. Simulation and test data indicate that the ceiling fan generates minimal noise when 0.5(r1-R)≤r3≤2(r1-R).

[0381] If r3 is too small, the transition surface 13314 will have difficulty guiding the airflow, causing the airflow to quickly escape from the transition surface 13314, thereby generating a loud noise. If r3 is too large, the transition surface 13314 will create a large resistance to the airflow, thereby generating a loud noise when the airflow collides with the guide 1331.

[0382] As can be seen from the above equation, r3 is positively correlated with r1-R. When r1-R decreases, the distance between the guide 1331 and the impeller 11 is closer. Therefore, the airflow from the impeller 11 reaches the guide 1331 at a higher velocity, resulting in a more intense collision between the airflow and the guide 1331. Increasing r3 in this situation will cause the transition surface 13314 to create greater resistance to the airflow, further increasing the noise generated when the airflow collides with the guide 1331. Therefore, r3 should be reduced to reduce wind noise.

[0383] In some examples, as shown in FIG61 , a transition surface 13314 is formed at the connection between the second air guide portion 13313 and the first air guide portion 13312. The transition surface 13314 has at least two locations with different distances from the central axis of the annular opening 1324.

[0384] For example, as shown in Figures 62 to 64, along the direction from the air inlet 111 toward the annular opening 1324, the distance between the transition surface 13314 and the central axis of the annular opening 1324 gradually increases, or first increases and then decreases, or first decreases and then increases; or at least a portion of the distance gradually increases, or first increases and then decreases, or first decreases and then increases. This prevents the airflow from colliding with various locations on the transition surface 13314 simultaneously, thereby reducing the intensity of the collision between the airflow and the transition surface 13314 and, in turn, reducing the noise generated by the airflow.

[0385] In some examples, as shown in Figures 59 and 60, along the rotation direction of the wind rotor 11 (or the circumference of the wind rotor 11), the second wind guide portion 13313 sequentially includes a first wind guide sub-surface 133131 and a second wind guide sub-surface 133132. The second wind guide sub-surface 133132 is arc-shaped, with the convex surface of the second wind guide sub-surface 133132 facing the wind rotor 11.

[0386] On the one hand, the second sub-wind guide surface 133132 can deflect the wind flow toward the radial direction of the wind wheel 11. This ensures that the airflow has a larger radial component after flowing into the air outlet gap 13241, which helps the airflow to blow a longer distance. Furthermore, because the concave surface of the first wind guide portion 13312 faces the second wind guide portion 13313 of the other air guide member 1331, the angle between the first wind guide portion 13312 and the second sub-wind guide surface 133132 of the other air guide member 1331 is relatively small. Thus, the angle between the airflow near the second sub-wind guide surface 133132 in the air outlet gap 13241 and the airflow near the first wind guide portion 13312 is relatively small, making the wind direction more uniform throughout the air outlet gap 13241, thereby improving the uniformity of the air outflow from the air outlet gap 13241.

[0387] On the other hand, the radial deflection of the second wind guide surface 133132 toward the rotor 11 can reduce the central angle of the guide member 1331 without reducing the wind guide length of the second wind guide portion 13313, even if the central angle of the wind gap 13241 is larger. In this way, the wind blown out of the annular opening 1324 can be continuous, that is, the wind blown out of the annular opening 1324 is more uniform.

[0388] In some examples, as shown in FIG55 , within a reference plane, let the angle between the tangent of the end of the second sub-air-guiding surface 133132 and the line connecting the end of the second sub-air-guiding surface 133132 and the central axis of the annular opening 1324 be ω, then 0°<ω<20°. This allows the angle between the wind direction at the end of the second sub-air-guiding surface 133132 and the radial direction of the annular opening 1324 to be smaller, which is beneficial for increasing the radial air supply distance of the ceiling fan. At the same time, the wind direction at the end of the second sub-air-guiding surface 133132 can be made close to the wind direction at the end of the first air-guiding portion 13312, thereby making the air discharge from the air gap 13241 more uniform.

[0389] In some examples, as shown in FIG55 , the first sub-air guide surface 133131 and the second sub-air guide surface 133132 are tangent at their connection, thereby allowing airflow to flow smoothly from the first sub-air guide surface to the second sub-air guide surface 133132, thereby reducing airflow losses. This also prevents airflow from rapidly escaping from the first sub-air guide surface 133131, thereby reducing noise generated by the airflow.

[0390] In some examples, the concave surface of the first sub-wind guiding surface 133131 faces the wind wheel 11 , which is conducive to gathering the airflow and guiding the airflow to the second sub-wind guiding surface 133132 .

[0391] In some examples, as shown in FIG55 , assuming that the distance between the end of the first sub-wind guide surface 133131 and the axis of the wind wheel 11 is r2, and 1.015<r2 / r1<1.2, it is beneficial for the first sub-wind guide surface 133131 to gather airflow and also beneficial for the first sub-wind guide surface 133131 to guide airflow to the second sub-wind guide surface 133132. If r2 / r1 is too small (e.g., r2 / r1<1), the first sub-wind guide surface 133131 will produce a large resistance to the airflow, resulting in airflow loss and causing a large noise when the airflow impacts the first sub-wind guide surface 133131. If r2 / r1 is too large, the angle of the first sub-wind guide surface 133131 will change too quickly, making it easy for the airflow to escape from the first sub-wind guide surface 133131, resulting in a large noise generated by the airflow.

[0392] In some examples, as shown in Figure 55, in the reference plane, the line between the end of the first sub-wind-guiding surface 133131 and the central axis of the annular opening 1324 is the tenth reference line d, and the angle between the ninth reference line b and the tenth reference line d is β, and β<α.

[0393] If β>α, the length of the second sub-wind guide surface 133132 will increase, so that the impact between the airflow and the second sub-wind guide surface 133132 is greater, thereby making the wind blown out by the wind wheel 11 encounter greater resistance, thereby increasing the load of the wind wheel 11.

[0394] In some examples, as shown in Figures 55 and 56 , duct assembly 132 includes a first duct member 1321 and a second duct member 1322, with first duct member 1321 surrounding second duct member 1322. The top of first duct member 1321 defines an air inlet gap 13211, and an annular opening 1324 is formed between the bottoms of first duct member 1321 and second duct member 1322. A flow guide 1331 is connected to the inner wall of the housing.

[0395] In some examples, the air inlet gap 13211 may also be located at a side of the first air duct component 1321 , or at a bottom of the second air duct component 1322 .

[0396] In some examples, as shown in Figures 52 and 53, the top of the air guide 1331 abuts against the first air duct member 1321, and / or the bottom of the air guide 1331 abuts against the second air duct member 1322, and along the air outlet direction, as shown in Figures 55 and 56, the vertical dimension of the air guide 1331 gradually decreases. Therefore, the spacing between the portions where the first and second air duct members 1321, 1322 abut against the air guide 1331 also decreases. Since the total amount of air output of the wind wheel 11 remains unchanged, and the spacing between the first and second air duct members 1321, 1322 gradually decreases along the airflow direction, the air pressure of the airflow gradually increases, thereby increasing the air supply distance of the fan.

[0397] In some examples, as shown in FIG56 , the first air duct member 1321 includes a first curved portion 13213, and the second air duct member 1322 includes a second curved portion 13222. The concave surface of the first curved portion 13213 faces the convex surface of the second curved portion 13222, and a plurality of air guides 1331 are positioned between the first curved portion 13213 and the second curved portion 13222. This allows the airflow from the impeller 11 to flow along the curved surface, resulting in smoother airflow and preventing airflow losses caused by sudden changes in the direction of the airflow.

[0398] In some examples, as shown in FIG56 , the top and bottom of the air guide 1331 are both curved and respectively conform to the first curved portion 13213 and the second curved portion 13222. The angle between the top of the air guide 1331 and / or the bottom of the air guide 1331 and the horizontal plane gradually increases along the air outlet direction. Since the wind wheel 11 blows the guide air horizontally, while the ceiling fan needs to blow air downward, the angle between the bottom of the air guide 1331 and the horizontal plane gradually increases along the air outlet direction, thereby gradually directing the airflow toward the vertical direction.

[0399] In some examples, as shown in FIG56 , the maximum vertical dimension of the air guide 1331 is d1, the width of the air outlet gap 13241 is d2, and 2.5<d1 / d2<7. <d1 / d2<6。

[0400] Since the diameter of the first air duct component 1321 and the diameter of the second air duct component 1322 are larger than the diameter of the wind wheel 11, if d1 / d2 is too small, it may still cause the ventilation area of ​​the annular opening 1324 (the ventilation area between the end of the first arc portion 13213 and the end of the second arc portion 13222) to be larger than the ventilation area of ​​the edge of the wind wheel 11, thereby causing the flow rate of the airflow in the air duct to gradually decrease, causing the airflow to easily generate vortices in the air duct, thereby resulting in a shorter air supply distance of the annular opening 1324.

[0401] If d1 / d2 is too large, although the ventilation area of ​​the annular opening 1324 will be smaller than the ventilation area of ​​the edge of the wind wheel 11, the ventilation area of ​​the annular opening 1324 will hinder the airflow, making the air output at the annular opening 1324 too small, which is not conducive to increasing the air supply distance and will also generate greater noise.

[0402] In some examples, a transition surface 13314 is formed at the junction of the second air guide portion 13313 and the first air guide portion 13312. The transition surface 13314 has different radii at at least two locations. This prevents the airflow from colliding with the entire second air guide portion 13313 simultaneously, thereby reducing the intensity of the collision between the airflow and the second air guide portion 13313 and further reducing the noise generated by the airflow.

[0403] Illustratively, along the direction from the air inlet 111 to the annular opening 1324 , the radius of the transition surface 13314 gradually decreases.

[0404] In some examples, transition surface 13314 is a chamfer between second air guide portion 13313 and first air guide portion 13312. The radius of transition surface 13314 is the chamfer radius. Along the direction from air inlet 111 toward annular opening 1324, the radius of transition surface 13314 gradually increases or decreases, or at least partially increases or at least partially decreases.

[0405] In this way, on the one hand, along the direction approaching the air inlet 111, the distance r1 between the head end of the second air guide part 13313 and the central axis of the annular opening 1324 will gradually increase, so that the airflow will not collide with the entire second air guide part 13313 at the same time, but will first collide with the end of the second air guide part 13313 away from the annular opening 1324, and then collide with the end of the first air guide surface close to the annular opening 1324, thereby reducing the collision intensity between the airflow and the second air guide part 13313, and thus reducing the noise generated by the airflow. Correspondingly, as it moves away from the bottom of the air guide 1331, the distance between the head end of the first air guide portion 13312 and the central axis of the annular opening 1324 gradually decreases, so that the airflow will not collide with the entire first air guide portion 13312 at the same time, but will first collide with the end of the first air guide portion 13312 close to the annular opening 1324, and then collide with the end of the first air guide portion 13312 away from the annular opening 1324, thereby reducing the collision intensity between the airflow and the first air guide portion 13312, and further reducing the noise generated by the airflow.

[0406] On the other hand, when the air guide 1331 and the first air duct member 1321 are integrally injection molded, as shown in Figure 66, the air guide 1331 and the first air duct member 1321 are molded between an upper mold and a lower mold. The upper mold is located outside the first air duct member 1321, and the lower mold is located inside the first air duct member 1321. After the air guide 1331 and the first air duct member 1321 are molded, the upper and lower molds need to be removed.

[0407] As shown in Figure 66, when removing the film, the upper mold is pulled out along a first direction, where the first air duct member 1321 gradually approaches the air inlet gap 13211 along the axial direction. A protrusion is formed on the inner side of the upper mold opposite the air guide 1331, and the protrusion is located on the inner side of the outer surface of the air guide 1331.

[0408] As shown in Figure 67 , if the radius r3 of the transition surface 13314 gradually decreases as it approaches the air inlet gap 13211 (closer to the axis of rotation), the distance between the second air guide portion 13313 and the first air guide portion 13312 of the air guide member 1331 will gradually decrease along the first direction. This will prevent the protrusion from being removed from the upper mold due to the obstruction between the second air guide portion 13313 and the first air guide portion 13312, preventing demolding. As shown in Figure 68 , if the radius r3 of the transition surface 13314 gradually increases as it approaches the air inlet gap 13211, the distance between the second air guide portion 13313 and the first air guide portion 13312 of the air guide member 1331 will gradually increase along the first direction. This will allow the protrusion to be smoothly removed from the second air guide portion 13313 and the first air guide portion 13312 during demolding.

[0409] As shown in Figure 66, when removing the film, the lower mold is pulled out along the second direction, where the second direction is the direction in which the first air duct member 1321 gradually moves axially away from the air inlet gap 13211. A groove is formed at the position where the lower mold and the guide member 1331 face each other, and the groove is located on the outer side of the inner surface of the guide member 1331.

[0410] As shown in Figure 69 , if the radius r3 of the transition surface 13314 gradually decreases as it approaches the air inlet 111, the distance between the second air guide portion 13313 and the first air guide portion 13312 of the air guide member 1331 will gradually increase along the second direction. This will prevent the groove from being blocked by the second air guide portion 13313 and the first air guide portion 13312 when the lower mold is removed, preventing demolding. As shown in Figure 70 , if the radius r3 of the transition surface 13314 gradually increases as it approaches the air inlet 111, the distance between the second air guide portion 13313 and the first air guide portion 13312 of the air guide member 1331 will gradually decrease along the second direction. This allows the protrusion to be smoothly removed from the second air guide portion 13313 and the first air guide portion 13312 during demolding.

[0411] Of course, in other examples, the air guide 1331 may also be an integral structure with the second air duct component 1322. Alternatively, the air guide 1331 is a separate component connected to the first air duct component 1321 and the second air duct component 1322 via the connecting portion 1132.

[0412] In some examples, as shown in FIG56 , the second duct member 1322 is connected to the bottom of the guide member 1331, thereby achieving the connection between the second duct member 1322 and the first duct member 1321. Since the airflow generated by the wind wheel 11 does not flow out from the position of the guide member 1331 opposite the annular opening 1324, the connecting portion 1132 (such as bolts and screws) is set at the bottom of the guide member 1331 so as not to hinder the flow of air.

[0413] In some examples, the outer wall surface of the first air duct component 1321 is covered with sound-absorbing cotton to reduce the noise generated by the air flow.

[0414] It should be noted that, in some embodiments, the concave and convex surfaces referred to in the article refer to the general direction of the surface. In other embodiments, local convex surfaces may be provided in the concave surface for other effects.

[0415] The embodiment of the present disclosure further provides a fan light, which includes the above-mentioned ceiling fan and a lighting mechanism 2, which can also be called a light module. The light module is arranged at the bottom of the air duct assembly 132 of the ceiling fan.

[0416] In some examples, as shown in FIG65 , the fan light further includes an outer shell 131 surrounding a first air duct component 1321. The outer shell 131 has an air inlet 1311, which is opposite to the air inlet 111 on the fan wheel 11 and the air inlet gap 13211 on the air duct component 132.

[0417] In some examples, as shown in Figures 49 and 56 , the second air duct member 1322 has a receiving slot. The lighting mechanism 2 can directly place the light source in the receiving slot, in which case the second air duct member 1322 can be considered a mounting base for the light source. Alternatively, the light module is a single integral component, removably connected to the bottom of the second air duct member 1322.

[0418] The following is an exemplary description of the implementation of the wind wheel.

[0419] In some examples, as shown in Figures 71 and 72, a fan mechanism 1 includes a rotor 11 and a motor 12. The rotor 11 includes a base plate 113 and a plurality of blades 115. The plurality of blades 115 are fixed to the base plate 113 and surround an air inlet gap 13211. The motor 12 includes a main body 126 and an output shaft 127. The output shaft 127 is rotatably connected to the main body 126. The main body 126 is located below the base plate 113 and the output shaft 127 passes through the base plate 113. In some embodiments, the motor 12 can be an outer rotor motor 12. The main body 126 can include a rotor assembly 123, such as a rotor sleeve 1231 and a flange 1232. The output shaft 127 can be a stator shaft 1221. Alternatively, the motor 12 can be an inner rotor motor 12. The main body 126 can be an outer stator assembly 125, and the output shaft 127 can be a rotor shaft 124.

[0420] Assuming that the radial distance between the top of the leading edge 1151 of the blade 115 and the top of the main body 126 is L1, and the radial distance between the bottom of the leading edge 1151 and the top of the main body 126 is L2, then L1>L2, wherein the leading edge 1151 is the edge of the blade 115 close to the air inlet gap 13211.

[0421] The technical solution provided by the disclosed embodiments provides that the greater the radial distance between the leading edge 1151 and the top of the main body 126, the further the leading edge 1151 is from the air inlet gap 13211, thereby reducing the air intake through the leading edge 1151. Setting L1 > L2 allows the top of the leading edge 1151 to be further away from the air inlet gap 13211, thereby reducing the air intake through the leading edge 1151. Because wind speeds increase and noise levels increase closer to the top of the leading edge 1151, reducing the air intake through the leading edge 1151 can reduce fan light noise.

[0422] In some examples, as shown in Figures 74 to 76, the leading edge 1151 of the blade 115 has a convex structure 11511, and the convex structure 11511 is located between the top and the bottom of the leading edge 1151.

[0423] In some examples, as shown in Figures 77 and 77 , assuming that the distance between the top of leading edge 1151 and the central axis of annular opening 1324 is R1, the distance between the bottom of leading edge 1151 and the central axis of annular opening 1324 is R2, and the distance between convex structure 11511 and the central axis of annular opening 1324 is R3, then R1>R2>R3. Since convex structure 11511 is located at the frontmost side of leading edge 1151, the distance R3 between convex structure 11511 and the central axis of annular opening 1324 is the smallest, so both R1 and R2 are greater than R3. This allows convex structure 11511 to change the direction of airflow as early as possible, thereby reducing vortices and, in turn, wind noise.

[0424] The greater the distance between the leading edge 1151 and the central axis of the annular opening 1324, the farther the leading edge 1151 is from the air inlet gap 13211, and thus the less the air intake of the leading edge 1151. Setting R1 > R2 can reduce the air intake at the top of the leading edge 1151. Since the wind speed is higher near the top of the leading edge 1151 and the generated noise is greater, reducing the air intake at the top of the leading edge 1151 can reduce the noise of the fan light.

[0425] In some examples, as shown in FIG. 77, let the height of the leading edge 1151 be H1, and the height of the forward convex structure 11511 from the bottom plate 113 be H2, then 0.5H1 < H2 ≤ 0.8H1. Through simulation and test data, it is obtained that when 0.5H1 < H2 ≤ 0.8H1, the noise reduction effect of the leading edge 1151 is the best. If the height H2 of the forward convex structure 11511 from the bottom plate 113 is too high, the distance between the forward convex structure 11511 and the top of the leading edge 1151 will be too small. According to aerodynamics, the smaller the cross-sectional area of the space through which the air flow passes, the faster the air flow velocity. Therefore, if the distance between the forward convex structure 11511 and the top of the leading edge 1151 is too small, it will cause the air flow velocity between the forward convex structure 11511 and the top of the leading edge 1151 to be relatively fast, and further make the wind noise here relatively large, which is not conducive to reducing the wind noise of the wind wheel 11.

[0426] In some examples, as shown in FIGS. 71 and 72, the top of the main body 126 is higher than the bottom of the trailing edge 1152 of the blade 115, where the trailing edge 1152 is opposite to the leading edge 1151. In this way, the main body 126 can make full use of the space inside the wind wheel 11, so that the height of the wind wheel 11 is smaller, and further the volume of the fan light is smaller.

[0427] In some examples, as shown in FIG. 72, let the axial distance between the top of the trailing edge 1152 of the blade 115 and the top of the main body 126 be L3, and the axial distance between the bottom of the trailing edge 1152 and the top of the main body 126 be L4, then L3 > L4, so that the trailing edge 1152 of the blade 115 can guide the air flow as much as possible. If L4 > L3, most of the trailing edge 1152 will be lower than the top of the main body 126, which may cause the gas flowing from the leading edge 1151 of the blade to concentrate in the top area of the trailing edge 1152. On the one hand, the air flow at the trailing edge 1152 is uneven. On the other hand, it may cause the air flow to impact the top area of the trailing edge 1152 more strongly, thus generating greater noise.

[0428] Or, as shown in Figures 72 and 73, the fan lamp also includes a plurality of guide members 1331, and the plurality of guide members 1331 surround the wind wheel 11. Assuming that the axial distance between the top of the trailing edge 1152 of the blade 115 and the bottom of the head end of the guide member 1331 is L5, and the axial distance between the bottom of the trailing edge 1152 and the bottom of the head end of the guide member 1331 is L6, then L5>L6.

[0429] The embodiment of the present disclosure does not specifically limit the shape of the guide member 1331. As shown in FIG50, the guide member 1331 may be in the shape of a shielding tongue. Alternatively, as shown in FIG74, the guide member 1331 may be in the shape of a sheet.

[0430] In some examples, as shown in FIG73 , assuming that the axial distance between the top of the trailing edge 1152 of the blade 115 and the first side of the main body 126 is L7, and the first side distance between the bottom of the trailing edge 1152 and the bottom of the main body 126 is L8, then L7>L8. The first side of the main body 126 is the side of the main body 126 away from the base plate 113. Alternatively, the fan light further includes a plurality of deflectors 1331 surrounding the rotor 11. assuming that the axial distance between the top of the head end of the deflector 1331 and the bottom of the main body 126 is L9, and the axial distance between the bottom of the head end of the deflector 1331 and the bottom of the main body 126 is L10, then L9>L10. When the main body 126 extends into the interior of the rotor 11, the first side of the main body 126 is the top of the main body 126. When the main body 126 is located below the wind wheel 11 , the first side of the main body 126 is the bottom of the main body 126 .

[0431] In some examples, as shown in Figures 77 and 79 , the distance between the trailing edge 1152 of the blade 115 and the central axis of the annular opening 1324 gradually decreases as it approaches the base plate 113, with the trailing edge 1152 being opposite the leading edge 1151. This prevents airflow distributed axially along the trailing edge 1152 from simultaneously escaping from the trailing edge 1152. Airflow escaping from the trailing edge 1152 is one of the main causes of wind noise generated by the blade 115. Therefore, preventing airflow from escaping from the trailing edge 1152 simultaneously can reduce wind noise at the trailing edge 1152.

[0432] In some examples, as shown in FIG79 , the rate at which the distance between the trailing edge 1152 of the blade 115 and the central axis of the annular opening 1324 decreases gradually decreases as it approaches the base plate 113. If the rate at which the distance between the trailing edge 1152 and the central axis of the annular opening 1324 decreases remains high near the bottom, the base of the blade 115 will be too short, shortening the airflow acceleration path and causing the wind speed at the bottom of the trailing edge 1152 to be too low, which is not conducive to increasing the air supply distance of the fan lamp.

[0433] In some examples, as shown in FIG. 80 , on the same reference section, the angles between the leading edges 1151 of each two adjacent blades 115 and the central axis of the annular opening 1324 are not exactly the same, wherein the reference section is perpendicular to the central axis of the annular opening 1324 .

[0434] In the related art, the reason why the wind rotor 11 generates strong discrete noise is that the multiple blades 115 are evenly distributed in the circumferential direction. As a result, the pulsation frequency generated when the airflow strikes any blade 115 is the same, which increases the pulsation frequency of the wind rotor 11 and leads to higher noise from the wind rotor 11. Therefore, in the embodiment of the present disclosure, the angle between the leading edge 1151 of each two adjacent blades 115 and the central axis is set to be different. This can prevent the airflow from colliding with the leading edges 1151 of multiple blades 115 at the same time, thereby reducing the wind noise of the wind rotor 11.

[0435] The present disclosure also provides a wind wheel 11, as shown in Figures 75 and 76. The wind wheel 11 includes a base plate 113 and a plurality of blades 115, and the plurality of blades 115 are fixed to the base plate 113. As shown in Figures 74 and 75, the leading edge 1151 of the blade 115 has a convex structure 11511, wherein the leading edge 1151 is the edge of the blade 115 close to the central axis O of the wind wheel 11. As shown in Figure 77, assuming that the height of the leading edge 1151 is H1 and the height of the convex structure 11511 from the base plate 113 is H2, then 0.5H1 <H2≤0.8H1。

[0436] In some examples, as shown in Figures 75 and 76, the wind rotor 11 may further include a top plate 114, with a plurality of blades 115 fixed between the top plate 114 and the bottom plate 113. The top plate 114 has an air inlet 111, and the plurality of blades 115 surround the air inlet 111. An air outlet 112 is formed between the edge of the top plate 114 and the edge of the bottom plate 113. The trailing edges 1152 of the blades 115 divide the air outlet 112 into a plurality of air outlet gaps 13241. When the wind rotor 11 rotates, airflow enters the interior of the wind rotor 11 through the air inlet 111, is accelerated by the blades 115, and then flows out through the air outlet 112.

[0437] In the technical solution provided by the embodiments of the present disclosure, when the wind wheel 11 operates, air flow enters the interior of the wind wheel 11 and flows towards the leading edge 1151 of the blade 115. The leading edge 1151 has a forward convex structure 11511, and the forward convex structure 11511 is a bionic design of the convex structure of the leading edge of a bird wing. The convex structure of the leading edge of a bird wing can change the direction of gas flow, reduce the eddy current in the air flow, and thus reduce the air resistance during flight. According to the principle of bionics, the forward convex structure 11511 can imitate the convex structure of the leading edge of a bird wing to reduce the eddy current at the leading edge 1151 of the blade 115, making the air flow smoother, so that the air resistance received by the leading edge 1151 of the blade 115 is smaller, and further reducing the wind noise at the leading edge 1151. Moreover, setting the forward convex structure 11511 at the leading edge 1151 can make the local mass of the leading edge 1151 larger, thereby reducing the vibration of the blade 115 caused by aerodynamic force, and thus reducing the noise.

[0438] In addition, since the upper half region of the leading edge 1151 of the blade 115 is closer to the air inlet gap 13211, the wind speed in the upper half region of the leading edge 1151 is greater. According to aerodynamics, the greater the wind speed, the easier it is to generate eddy currents, resulting in greater wind noise. Therefore, reducing the eddy current in the upper half region of the leading edge 1151 can achieve a good noise reduction effect on the wind wheel 11. Therefore, setting H2 > 0.5H1 can make the forward convex structure 11511 closer to the upper half region of the leading edge 1151, thereby reducing the air resistance in the upper half region of the leading edge 1151, and thus making the wind noise in the upper half region of the leading edge 1151 smaller.

[0439] Through simulation and test data, it is obtained that when 0.5H1 < H2 ≤ 0.8H1, the noise reduction effect of the leading edge 1151 is the best. If the height H2 of the forward convex structure 11511 from the bottom plate 113 is too high, the distance between the forward convex structure 11511 and the top of the leading edge 1151 will be too small. According to aerodynamics, the smaller the cross-sectional area of the space through which the air flow passes, the faster the air flow velocity. Therefore, if the distance between the forward convex structure 11511 and the top of the leading edge 1151 is too small, it will cause the air flow velocity between the forward convex structure 11511 and the top of the leading edge 1151 to be faster, resulting in greater wind noise here, which is not conducive to reducing the wind noise of the wind wheel 11.

[0440] In some examples, as shown in FIG. 77, let the distance between the forward convex structure 11511 and the central axis O of the wind wheel 11 be R3, the distance between the bottom of the leading edge 1151 and the central axis O be R2, and the distance between the top of the leading edge 1151 and the central axis O be R1, then R1 > R2 > R2.

[0441] Since the convex structure 11511 is located at the frontmost side of the leading edge 1151, the distance R3 between the convex structure 11511 and the central axis O is the smallest, so R1 and R2 are both greater than R3. In this way, the convex structure 11511 can change the airflow direction as early as possible, thereby reducing vortex and thus reducing wind noise.

[0442] The closer the distance between leading edge 1151 and central axis O, the closer leading edge 11511 is to air inlet gap 13211, allowing it to guide the airflow sooner, thereby increasing the air intake of leading edge 11511. Therefore, setting R1 > R2 allows for a higher air intake at the bottom of leading edge 11511 and a lower air intake at the top. Given the same air intake at air inlet gap 11511, the air intake at the bottom of leading edge 11511 is higher, while the air intake at the top of leading edge 11511 is lower. Because the wind speed at the bottom of leading edge 1151 is lower, the noise generated is also lower. Therefore, a higher air intake at the bottom of leading edge 1151 results in lower noise generated by blade 115.

[0443] In some examples, as shown in Figures 78 and 79 , the distance between the trailing edge 1152 of the blade 115 and the central axis O of the rotor 11 gradually decreases as it approaches the base plate 113, with the trailing edge 1152 facing the leading edge 1151. This prevents airflow distributed axially along the trailing edge 1152 from simultaneously escaping from the trailing edge 1152. Airflow escaping from the trailing edge 1152 is one of the main causes of wind noise generated by the blade 115. Therefore, preventing airflow from escaping from the trailing edge 1152 simultaneously can reduce wind noise at the trailing edge 1152.

[0444] In some examples, as shown in Figures 78 and 79, let the distance between the bottom of the trailing edge 1152 and the central axis O be D1, the distance between the top of the trailing edge 1152 and the central axis O be D2, and the height of the trailing edge 1152 be H3, then 0.05H3≤D2-D1≤0.1H3.

[0445] Assuming ΔD = D2 - D1, if ΔD is too small, the airflow will easily escape from both the top and bottom of trailing edge 1152, hindering wind noise reduction at trailing edge 1152. Since blades 115 cannot extend beyond the outer edge of base plate 113, if ΔD is too large, the bottom of trailing edge 1152 will be too short, shortening the airflow path at the bottom of trailing edge 1152. This will cause the airflow velocity and pressure at the bottom of trailing edge 1152 to be significantly lower than those at the top of trailing edge 1152, leading to uneven pressure distribution at trailing edge 1152. This, in turn, affects the stable operation of wind rotor 11 and may increase wind rotor 11 noise. Simulation and test data indicate that when 0.05H3 ≤ ΔD ≤ 0.1H3, wind rotor 11 generates minimal noise.

[0446] In some examples, as shown in FIG79 , the trailing edge 1152 is concave in the longitudinal cross-section of the blade 115. Since the airflow velocity is higher in the middle and lower portions of the trailing edge 1152, configuring the trailing edge 1152 to be concave allows the airflow in the middle and lower portions to separate from the trailing edge 1152 as early as possible, thereby reducing the acceleration path of the airflow in the middle and lower portions of the trailing edge 1152. This results in a lower airflow velocity there, which helps reduce wind noise at the trailing edge 1152.

[0447] In some examples, as shown in FIG80 , on the same reference cross section, the angles between the leading edges 1151 of each two adjacent blades 115 and the central axis O of the wind rotor 11 are not exactly the same.

[0448] In the related art, the reason why the wind rotor 11 generates strong discrete noise is that the multiple blades 115 are evenly distributed in the circumferential direction. As a result, the pulsation frequency generated when the airflow strikes any blade 115 is the same, which increases the pulsation frequency of the wind rotor 11 and leads to higher noise from the wind rotor 11. Therefore, in the embodiment of the present disclosure, the angle between the leading edge 1151 of each two adjacent blades 115 and the central axis O of the wind rotor 11 is set to be different. This can prevent the airflow from colliding with the leading edges 1151 of multiple blades 115 at the same time, thereby reducing the wind noise of the wind rotor 11.

[0449] The above design results in a non-uniform distribution of the multiple blades 115, which may cause the center of gravity of the rotor 11 to deviate from its geometric center, making it difficult for the rotor 11 to achieve dynamic balance during rotation, and thus causing vibration during rotation. Therefore, to ensure that the blades 115 can reduce noise while also aligning the center of gravity with the geometric center of the rotor 11, the disclosed embodiment uses a sinusoidal frequency modulated unequally spaced angle distribution formula to calculate the angle between the leading edges 1151 of each pair of adjacent blades 115 and the line connecting the central axis O of the rotor 11.

[0450] In some examples, as shown in FIG. 80 , the wind wheel 11 includes seven blades 115 .

[0451] Based on the formula αi = αi' + Δαsin(Kαi'), the angle between the leading edge 1151 of each adjacent pair of blades 115 and the line connecting the central axis O of the wind rotor is determined. K is the number of groupings, and in this application, K can be set to 1. αi' is the circumferential arrangement angle of the i-th blade 115 when the blades 115 are uniformly arranged (the angle between the lines connecting the i-th blade 115 and the (i+1)-th blade 115 and the central axis O of the wind rotor). αi is the circumferential arrangement angle of the i-th blade 115 when the blades 115 are non-uniformly arranged, and Δα is the phase modulation amount. Δα = 360° × non-uniformity coefficient / number of blades, and the non-uniformity coefficient can be defined by oneself (e.g., 0.44).

[0452] On the same reference section, it is assumed that the angles formed by the leading edges 1151 of every two adjacent blades 115 and the central axis O of the wind wheel are α1, α2, α3, α4, α5, α6 and α7 respectively. Calculation shows that α1...α7 are 57.22°, 47.42°, 47.42°, 57.22°, 52.86°, 45° and 52.86° respectively.

[0453] Taking into account the precision and tolerance of the rotor injection molding process, the angles formed between the leading edges 1151 of each pair of adjacent blades 115 and the rotor's central axis O are set to 56.5°-57.5°, 47.0°-48.0°, 47.0°-48.0°, 56.5°-57.5°, 52.5°-53.5°, 44.5°-45.5°, and 52.5°-53.5°, respectively. This reduces wind noise from the rotor and ensures that the rotor's center of gravity and geometric center coincide as closely as possible.

[0454] In some examples, as shown in Figure 78 , in a longitudinal cross-section of blade 115, the area between forward convex structure 11511 and the top of leading edge 1151 is convex, while the area between forward convex structure 11511 and the bottom of leading edge 1151 is concave. Simulations and tests have shown that configuring leading edge 1151 in this shape helps reduce wind noise at leading edge 1151.

[0455] In some examples, as shown in FIG80 , the end surface of the leading edge 1151 of the blade 115 is curved throughout its cross section. Compared to a flat end surface of the leading edge 1151, the curved shape creates less resistance to airflow and provides better airflow cutting and guidance, thereby reducing wind noise from the rotor.

[0456] In some examples, as shown in FIG80 , the thickness of blade 115 increases and then decreases as it approaches trailing edge 1152. The cross-section of blade 115 can be a NACA 6508 airfoil, making boundary layer separation less likely to occur on the surface of blade 115. Aerodynamics shows that boundary layer separation is one of the main causes of wind noise generated by blades. Therefore, reducing boundary layer separation on the surface of blade 115 can reduce the aerodynamic noise of the wind rotor.

[0457] The technical solution provided by the embodiment of the present disclosure can make the fan lamp generate less noise when working, because the fan wheel in the fan lamp generates less noise when rotating, thereby bringing a good user experience.

[0458] It should be noted that, in some embodiments, the concave and convex surfaces referred to in the article refer to the general direction of the surface. In other embodiments, local convex surfaces may be provided in the concave surface for other effects.

[0459] The present disclosure further provides a fan lamp, which includes an air duct assembly 132 and a wind wheel 11 . The wind wheel 11 is located inside the air duct assembly 132 .

[0460] In some examples, as shown in FIG73 , the wind rotor 2 includes a base plate 22 and a plurality of blades 23, wherein the plurality of blades 23 are fixed to the base plate 22. As shown in FIG74 and FIG75 , the leading edge 1151 of the blade 115 has a convex structure 11511, wherein the leading edge 1151 is the edge of the blade 115 close to the central axis O of the wind rotor 11. As shown in FIG77 , assuming that the height of the leading edge 1151 is H1 and the height of the convex structure 11511 from the base plate 113 is H2, then 0.5H1 <H2≤0.8H1。

[0461] Convex structure 11511 is a biomimetic design inspired by the raised structure on the leading edge of a bird's wing. This raised structure on the leading edge of a bird's wing can redirect gas flow, reducing vortices in the airflow and thereby reducing air resistance during flight. Based on biomimetic principles, convex structure 11511 can mimic the raised structure on the leading edge of a bird's wing to reduce vortices at leading edge 1151 of blade 115, resulting in smoother airflow and less air resistance at leading edge 1151 of blade 115, thereby reducing wind noise at leading edge 1151. Furthermore, providing convex structure 11511 on leading edge 1151 increases the local mass of leading edge 1151, thereby reducing vibration of blade 115 caused by aerodynamic forces and, consequently, noise.

[0462] In addition, since the upper half region of the leading edge 1151 of the blade 115 is closer to the air inlet gap 13211, the wind speed in the upper half region of the leading edge 1151 is greater. According to aerodynamics, the greater the wind speed, the easier it is to generate eddy currents, resulting in greater wind noise. Therefore, reducing the eddy currents in the upper half region of the leading edge 1151 can achieve a good noise reduction effect on the wind turbine 11. Thus, setting H2 > 0.5H1 can make the forward convex structure 11511 closer to the upper half region of the leading edge 1151, thereby reducing the air resistance in the upper half region of the leading edge 1151, and thus making the wind noise in the upper half region of the leading edge 1151 smaller.

[0463] Through simulation and test data, it is obtained that when 0.5H1 < H2 ≤ 0.8H1, the noise reduction effect of the leading edge 1151 is the best. If the height H2 of the forward convex structure 11511 from the bottom plate 113 is too high, the distance between the forward convex structure 11511 and the top of the leading edge 1151 will be too small. According to aerodynamics, the smaller the cross-sectional area of the space through which the air flow passes, the faster the air flow velocity. Therefore, if the distance between the forward convex structure 11511 and the top of the leading edge 1151 is too small, it will cause the air flow velocity between the forward convex structure 11511 and the top of the leading edge 1151 to be relatively fast, thereby making the wind noise here greater, which is not conducive to reducing the wind noise of the wind turbine 11.

[0464] In some examples, as shown in FIG. 77, let the distance between the forward convex structure 11511 and the central axis O of the wind turbine 11 be R3, the distance between the bottom of the leading edge 1151 and the central axis O be R2, and the distance between the top of the leading edge 1151 and the central axis O be R1. Then R1 > R2 > R2.

[0465] Since the forward convex structure 11511 is located at the foremost side of the leading edge 1151, the distance R3 between the forward convex structure 11511 and the central axis O is the smallest. Therefore, both R1 and R2 are greater than R3. In this way, the forward convex structure 11511 can change the air flow direction earlier, thereby reducing eddy currents and further reducing wind noise.

[0466] The closer the leading edge 1151 is to the central axis O, the closer the leading edge 11511 is to the air inlet gap 13211, and the earlier it can guide the air flow, resulting in a greater air intake volume of the leading edge 11511. Therefore, setting R1 > R2 can make the air intake volume at the bottom of the leading edge 11511 larger and the air intake volume at the top smaller. When the air intake volume of the air inlet gap 11511 is the same, the larger the air intake volume at the bottom of the leading edge 11511 and the smaller the air intake volume at the top of the leading edge 11511. Since the wind speed at the bottom of the leading edge 1151 is lower and the generated noise is also lower, the more air intake volume at the bottom of the leading edge 1151, the smaller the noise generated by the blade 115.

[0467] In some examples, as shown in Figures 78 and 79 , the distance between the trailing edge 1152 of the blade 115 and the central axis O of the rotor 11 gradually decreases as it approaches the base plate 113, with the trailing edge 1152 facing the leading edge 1151. This prevents airflow distributed axially along the trailing edge 1152 from simultaneously escaping from the trailing edge 1152. Airflow escaping from the trailing edge 1152 is one of the main causes of wind noise generated by the blade 115. Therefore, preventing airflow from escaping from the trailing edge 1152 simultaneously can reduce wind noise at the trailing edge 1152.

[0468] In some examples, as shown in Figures 78 and 79, let the distance between the bottom of the trailing edge 1152 and the central axis O be D1, the distance between the top of the trailing edge 1152 and the central axis O be D2, and the height of the trailing edge 1152 be H3, then 0.05H3≤D2-D1≤0.1H3.

[0469] Assuming ΔD = D2 - D1, if ΔD is too small, the airflow will easily escape from both the top and bottom of trailing edge 1152, hindering wind noise reduction at trailing edge 1152. Since blades 115 cannot extend beyond the outer edge of base plate 113, if ΔD is too large, the bottom of trailing edge 1152 will be too short, shortening the airflow path at the bottom of trailing edge 1152. This will cause the airflow velocity and pressure at the bottom of trailing edge 1152 to be significantly lower than those at the top of trailing edge 1152, leading to uneven pressure distribution at trailing edge 1152. This, in turn, affects the stable operation of wind rotor 11 and may increase wind rotor 11 noise. Simulation and test data indicate that when 0.05H3 ≤ ΔD ≤ 0.1H3, wind rotor 11 generates minimal noise.

[0470] In some examples, as shown in FIG80 , on the same reference cross section, the angles between the leading edges 1151 of each two adjacent blades 115 and the central axis O of the wind rotor 11 are not exactly the same.

[0471] In the related art, the reason why the wind rotor 11 generates strong discrete noise is that the multiple blades 115 are evenly distributed in the circumferential direction. As a result, the pulsation frequency generated when the airflow strikes any blade 115 is the same, which increases the pulsation frequency of the wind rotor 11 and leads to higher noise from the wind rotor 11. Therefore, in the embodiment of the present disclosure, the angle between the leading edge 1151 of each two adjacent blades 115 and the central axis O of the wind rotor 11 is set to be different. This can prevent the airflow from colliding with the leading edges 1151 of multiple blades 115 at the same time, thereby reducing the wind noise of the wind rotor 11.

[0472] The above design results in a non-uniform distribution of blades 115, which may cause the center of gravity of the rotor 11 to deviate from the geometric center of the rotor 2, making it difficult for the rotor 11 to achieve dynamic balance during rotation, and thus causing vibration of the rotor 2. Therefore, to ensure that the blades 115 can reduce noise while also aligning the center of gravity with the geometric center of the rotor, the embodiment of the present disclosure uses a sinusoidal frequency modulated unequally spaced angle distribution formula to calculate the angle between the leading edges 11511 of each pair of adjacent blades 115 and the line connecting the central axis O of the rotor.

[0473] In some examples, as shown in FIG. 80 , the rotor includes seven blades 115 .

[0474] Based on the formula αi = αi' + Δαsin(Kαi'), the angle between the leading edge 1151 of each adjacent pair of blades 115 and the line connecting the central axis O of the wind rotor is determined. K is the number of groupings, and in this application, K can be set to 1. αi' is the circumferential arrangement angle of the i-th blade 115 when the blades 115 are uniformly arranged (the angle between the lines connecting the i-th blade 115 and the (i+1)-th blade 115 and the central axis O of the wind rotor). αi is the circumferential arrangement angle of the i-th blade 115 when the blades 115 are non-uniformly arranged, and Δα is the phase modulation amount. Δα = 360° × non-uniformity coefficient / number of blades, and the non-uniformity coefficient can be defined by oneself (e.g., 0.44).

[0475] On the same reference section, it is assumed that the angles formed by the leading edges 1151 of every two adjacent blades 115 and the central axis O of the wind wheel are α1, α2, α3, α4, α5, α6 and α7 respectively. Calculation shows that α1...α7 are 57.22°, 47.42°, 47.42°, 57.22°, 52.86°, 45° and 52.86° respectively.

[0476] Taking into account the precision and tolerance of the rotor injection molding process, the angles formed between the leading edges 1151 of each pair of adjacent blades 115 and the rotor's central axis O are set to 56.5°-57.5°, 47.0°-48.0°, 47.0°-48.0°, 56.5°-57.5°, 52.5°-53.5°, 44.5°-45.5°, and 52.5°-53.5°, respectively. This reduces wind noise from the rotor and ensures that the rotor's center of gravity and geometric center coincide as closely as possible.
