[0070] The above drawings show clear embodiments of the present disclosure, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0071] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0072] The present disclosure provides a fan, such as Figure 1-3 as well as Figure 13-Figure 15As shown, it includes a support member 1, a first motor 2, a fan blade mounting component 3, a fan blade 4 and a guide wheel 5. The support member 1 is connected to the first stator 21 of the first motor 2, and the first rotor 22 of the first motor 2 is connected to the fan blade mounting component 3. There are multiple fan blades 4, and one end of the multiple fan blades 4 is connected to the fan blade mounting component 3. The guide wheel 5 is located on the air inlet side of the multiple fan blades 4 and is coaxial with the fan blade mounting component 3. The guide wheel 5 can rotate to guide the air at the first motor 2 or the fan blade mounting component 3 to the multiple fan blades 4.

[0073] The fan provided in the embodiment of the present disclosure has a guide wheel 5, which is located on the air inlet side of the multiple fan blades 4 and is coaxial with the fan blade mounting component 3. The guide wheel 5 can rotate to guide the air at the first motor 2 or the fan blade mounting component 3 to the multiple fan blades 4. Therefore, the fan provided in the embodiment of the present disclosure can not only drive the air at the fan blades 4, but also guide the air at the first motor 2 or the fan blade mounting component 3 in the middle area of ​​the multiple fan blades 4 to the fan blades 4 through the guide wheel 5. Therefore, the fan can also drive the air in the middle area of ​​the multiple fan blades 4, so that the fan has a higher working efficiency.

[0074] The embodiments of the present disclosure do not limit the type of fan. In some examples, the fan is a ceiling fan (referred to as a ceiling fan), and in other examples, the fan is a floor-standing fan.

[0075] Below, the fan structure is described in more detail by taking a ceiling fan and a floor-standing fan as examples:

[0076] The present disclosure provides a ceiling fan. Figure 1-Figure 3 As shown, the ceiling fan includes a support member 1, a first motor 2, a fan blade mounting component 3, a fan blade 4 and a guide wheel 5. The support member 1 is connected to the first stator 21 of the first motor 2, and the first rotor 22 of the first motor 2 is connected to the fan blade mounting component 3. There are multiple fan blades 4, and one end of the multiple fan blades 4 is connected to the fan blade mounting component 3. The guide wheel 5 is located on a side of the fan blade mounting component 3 close to the support member 1 and is coaxial with the fan blade mounting component 3. The guide wheel 5 can rotate to guide the air at the fan blade mounting component 3 to the multiple fan blades 4.

[0077] The support member 1 is a suspension rod, one end of which is used to be connected to the ceiling, and the other end of which is used to hang the rest of the ceiling fan.

[0078] The first motor 2 is a power component for rotating the fan blade mounting component 3 and the fan blade 4, and includes a first stator 21 and a first rotor 22. The first stator 21 is connected to the suspension rod, and the first rotor 22 can rotate relative to the first stator 21 and is used to drive the fan blade mounting component 3 to rotate.

[0079] The fan blade mounting component 3 may also be called a fan blade disk.

[0080] A plurality of blades 4 are fixed to the blade mounting member 3. In some examples, the plurality of blades 4 are evenly distributed along the circumference of the blade mounting member 3. The disclosed embodiment does not limit the number of blades 4. In some examples, the number of blades 4 is 4. Of course, the number of blades 4 can also be other numbers, such as 3, but is not limited thereto.

[0081] In some examples, the ceiling fan provided by the embodiments of the present disclosure is an invisible fan. When the ceiling fan rotates, the plurality of blades 4 are unfolded relative to the blade mounting component 3; when the ceiling fan does not rotate, the plurality of blades 4 are stored relative to the blade mounting component 3, thereby making the ceiling fan more beautiful. The implementation principle of storing and unfolding the blades 4 relative to the blade mounting component 3 can be the same as the implementation principle of the prior art, and the embodiments of the present disclosure do not limit this.

[0082] The guide wheel 5 can guide the air at the fan blade mounting component 3 to the plurality of fan blades 4, thereby increasing the air volume and air pressure of the ceiling fan without increasing the number of fan blades 4.

[0083] The ceiling fan provided in the embodiment of the present disclosure has a guide wheel 5, which is located on a side of the fan blade mounting component 3 close to the suspension rod and is coaxial with the fan blade mounting component 3. The guide wheel 5 can rotate to guide the air at the fan blade mounting component 3 to the plurality of fan blades 4. Therefore, the ceiling fan provided in the embodiment of the present disclosure can not only drive the air outside the fan blade mounting component 3, but also drive the air at the fan blade mounting component 3 through the guide wheel 5, thereby increasing the air volume and air pressure generated when the ceiling fan rotates, so that the working efficiency of the ceiling fan is higher.

[0084] The embodiment of the present disclosure does not limit the shape of the guide wind wheel 5. Figure 4-Figure 9 , the specific structure of the guide wind wheel 5 is described in more detail:

[0085] like Figure 4 As shown, the guide wind wheel 5 has a wind wheel body 51, and the outer diameter of the wind wheel body 51 gradually decreases in the direction away from the wind blades 4. The outer wall of the wind wheel body 51 has a plurality of wind guide structures 512, and the plurality of wind guide structures 512 are sequentially arranged along the circumference of the wind wheel body 51.

[0086] In some examples, the first end 512a of the wind guide structure 512 is close to the fan blade 4, the second end 512b is far away from the fan blade 4, and the projections of the first end 512a and the second end 512b on the first plane are arranged in sequence along the rotation direction of the guide wheel 5. The first plane is a plane perpendicular to the axis of the first rotor 22 of the first motor 2, which is a horizontal plane for a ceiling fan.

[0087] The embodiment of the present disclosure does not limit the formation method of the air guide structure 512.

[0088] In some examples, such as Figure 4 As shown, the wind wheel body 51 includes a wind guide structure mounting portion 511 and a plurality of wind guide structures 512. The outer diameter of the wind guide structure mounting portion 511 gradually decreases in a direction away from the wind blade 4. The wind guide structure 512 is in a sheet shape, and one side of the wind guide structure 512 is connected to the outer wall of the wind guide structure mounting portion 511.

[0089] In other examples, such as Figure 5 and Figure 6 As shown, the wind guiding structure 512 is formed by the outer wall of the wind wheel body 51 protruding outward.

[0090] by Figure 4 Taking the guide wheel 5 shown as an example, when the guide wheel 5 rotates, air flows in from between the second end 512b of the guide structure 512 and the guide structure mounting portion 511, and is blown out of the guide structure mounting portion 511 from between the first end 512a of the guide structure 512 and the guide structure mounting portion 511.

[0091] Since the air blown out from between the first end 512a of the wind guide structure 512 and the wind guide structure mounting portion 511 has a tendency to move downward, the fan blades 4 can cut the air guided by the guide wheel 5 more smoothly, making the ceiling fan blow more smoothly.

[0092] Furthermore, since the air guided by the guide wind wheel 5 tends to move downward, the wind pressure felt by the user is also greater.

[0093] In order to reduce the wind resistance encountered by the guide wind wheel 5 when the ceiling fan is started, in some examples, such as Figure 4 As shown, the width d of the end of the wind guiding structure 512 away from the fan blade 4 (the second end 512b) is smaller than the width d of the end of the wind guiding structure 512 close to the fan blade 4 (the first end 512a).

[0094] Since the second end 512b of the wind guide structure 512 is the main source of wind resistance, the width of the second end 512b of the wind guide structure 512 is set to be smaller, so that the contact area between the second end 512b of the wind guide structure 512 and the air becomes smaller, thereby reducing the wind resistance encountered when the guide wind wheel 5 is started.

[0095] In some examples, such as Figure 4 As shown, the width d of the wind guiding structure 512 gradually decreases along the direction away from the wind blade 4, that is, the width d of the wind guiding structure 512 gradually decreases along the direction from the first end 512a to the second end 512b.

[0096] certainly, Figure 4The wind guide structure 512 shown in the figure is only an example. In actual application, the width of the wind guide structure 512 can gradually increase along the direction from the first end 512a to the second end 512b, or the width of the wind guide structure 512 can also remain unchanged along the direction from the first end 512a to the second end 512b. The embodiments of the present disclosure do not make specific limitations on this.

[0097] Since the width of the second end 512b of the wind guide structure 512 is small, the amount of air entering from the second end 512b of the wind guide structure 512 to the space between the wind guide structure 512 and the wind guide structure mounting portion 511 is small, and the wind guide amount of the guide wheel 5 is small. In order to increase the wind guide amount of the guide wheel 5, in some examples, such as Figure 7 and Figure 8 As shown, the angle between the end of the wind guide structure 512 close to the fan blade 4 (i.e., the first end 512a) and the first plane is smaller than the angle between the end of the wind guide structure 512 away from the fan blade 4 (i.e., the second end 512b) and the first plane. The first plane is perpendicular to the axis of the first rotor 22.

[0098] In some examples, such as Figure 7 As shown, the angle between the wind guide structure 512 and the first plane gradually increases along the direction away from the fan blade 4, that is, the angle between the wind guide structure 512 and the first plane gradually increases (such as uniformly increases) along the direction from the first end 512a to the second end 512b. Figure 7 As shown, a1, a2 and a3 gradually increase.

[0099] In other examples, such as Figure 8 As shown, the angle between the wind guide structure 512 and the first plane increases gradually along the direction from the first end 512a to the second end 512b. Figure 8 As shown, a3 is equal to a2, and both are smaller than a1.

[0100] The disclosed embodiment does not limit the angle range of the angle between the wind guide structure 512 and the first plane. In some examples, the angle between the end of the wind guide structure 512 close to the wind blade 4 (i.e., the first end 512a) and the first plane is greater than 20° and less than 30°, and the angle between the end of the wind guide structure 512 away from the wind blade 4 (i.e., the second end 512b) and the first plane is greater than 25° and less than 35°.

[0101] The wind guide structure 512 with the above structure can further increase the air volume and air stability, reduce noise, and improve the comfort of use. Figure 7 and Figure 8The wind guide structure 512 shown in the figure is only an example. In actual applications, the angle between the wind guide structure 512 and the first plane can gradually decrease along the direction from the first end 512a to the second end 512b, or the angle between the wind guide structure 512 and the first plane can also remain unchanged along the direction from the first end 512a to the second end 512b. The embodiments of the present disclosure are not limited to this.

[0102] In some examples, such as Fig. 9 As shown, a plurality of wind guide structures 512 are evenly distributed along the circumference of the wind wheel body 51 , thereby making the wind guided out by the guide wind wheel 5 more uniform.

[0103] In some examples, such as Fig. 9 As shown, the number of the wind guiding structures 512 is an integer multiple of the number of the wind blades 4 .

[0104] In this way, each fan blade 4 receives the same amount of air guided by the air guide structure 512, so that each fan blade 4 is subjected to the same force, the rotation of the ceiling fan is more stable, and the air blowing of the ceiling fan is more uniform.

[0105] For example, Fig. 9 As shown, there are 4 fan blades and 16 wind guide structures 512 , so there are 4 wind guide structures 512 between every two fan blades 4 , and each fan blade 4 can receive the wind guided by the 4 wind guide structures 512 .

[0106] Of course, the number of the wind guide structures 512 may not be an integer multiple of the number of the fan blades 4, and the embodiment of the present disclosure does not limit this.

[0107] The embodiment of the present disclosure does not limit the rotation mode of the guide wheel 5. The guide wheel 5 can rotate together with the fan blade mounting component 3, or can rotate independently.

[0108] The following describes the configuration of the guide wind wheel 5 in the above two cases respectively:

[0109] (1) In some examples, the guide wheel 5 rotates together with the fan blade mounting component 3 .

[0110] For example, Figure 1 As shown, the guide wheel 5 is connected to the fan blade mounting component 3. When the fan blade mounting component 3 rotates, the guide wheel 5 and the fan blade 4 rotate synchronously with the fan blade mounting component 3, and the guide wheel 5 and the fan blade 4 have the same rotation speed.

[0111] The disclosed embodiment does not limit the connection method between the guide wheel 5 and the fan blade mounting component 3. In some examples, the guide wheel 5 and the fan blade mounting component 3 are fixedly connected by screws.

[0112] For example, Figure 4As shown, the guide wheel 5 further includes a flange 52, which is located on one side of the wind wheel body 51 close to the fan blade mounting component 3. The flange 52 has a plurality of screw holes 520, and the screws can pass through the screw holes 520 and be tightened in the fan blade mounting component 3, thereby connecting the flange 52 to the fan blade mounting component 3.

[0113] In some examples, the plurality of screw holes 520 are evenly distributed along the circumference of the guide wheel 5 .

[0114] The embodiment of the present disclosure does not limit the number of screw holes 520 . In some examples, there are four screw holes 520 , and the guide wheel 5 can be fixed to the fan blade mounting component 3 by four screws.

[0115] Of course, the guide wheel 5 can also be connected to the fan blade mounting component 3 in other ways, such as the guide wheel 5 can also be clamped with the fan blade mounting component 3, but it is not limited thereto.

[0116] The embodiment of the present disclosure does not limit the shape of the guide wind wheel 5. In some examples, such as Fig.10 As shown, the guide wind wheel 5 is in a cover shape and has an opening 50 along the axial direction. The guide wind wheel 5 covers the first motor 2, and the opening 50 surrounds the suspension rod or the first stator 21.

[0117] By setting the guide wind wheel 5 in a cover shape and covering the first motor 2, the guide wind wheel 5 can prevent dust from entering the first motor 2 to a certain extent, so that the guide wind wheel 5 provided in the embodiment of the present disclosure can also play a role in dust prevention. Therefore, the guide wind wheel 5 can also be called a dust cover, and the dust cover has both the guide function and the dust prevention function.

[0118] It should be noted that, in the case where the guide wheel 5 is also used for dust prevention, the guide wheel 5 can also be understood as an improvement on the dust cover of the ceiling fan so that it has both the dust prevention function and the guide function.

[0119] Specifically, the dust cover in the related art is fixed to the suspension rod and separated from the fan blade mounting component 3, and does not rotate with the fan blade mounting component 3. The technical solution provided by the embodiment of the present disclosure separates the dust cover from the suspension rod and fixes it to the fan blade mounting component 3, so that the dust cover can rotate. At the same time, an air guide structure 512 is provided on the outside of the dust cover, so that the dust cover has a flow guide function.

[0120] In addition, since the guide wheel 5 will rotate with the fan blade mounting component 3 relative to the suspension rod and the first stator 21, in order to prevent wear between the guide wheel 5 and the suspension rod or the first stator 21, there is a gap between the opening 50 and the suspension rod or the first stator 21.

[0121] In some examples, such as Fig.10As shown, in order to reduce the possibility of dust entering the interior of the guide wheel 5 through the opening 50 and the gap between the suspension rod or the first stator 21 , the ceiling fan also includes a decorative cover 6 , which is connected to the suspension rod and covers the opening 50 .

[0122] The size of the decorative cover 6 is larger than the size of the opening 50 .

[0123] The decorative cover 6 may also be called a dust cover or the like.

[0124] For example, Fig.10 As shown, the opening 50 is a circular hole, and the decorative cover 6 can be coaxial with the opening 50 , and the diameter of the decorative cover 6 is larger than the diameter of the opening 50 to cover the opening 50 .

[0125] The embodiment of the present disclosure does not limit the shape of the decorative cover 6. In some examples, such as Fig.10 As shown, the decorative cover 6 is in a hood shape. In other examples, the decorative cover 6 can also be in a sheet shape.

[0126] In addition, since the decorative cover 6 does not rotate, relative movement occurs between the guide wheel 5 and the decorative cover 6 . In order to avoid wear between the guide wheel 5 and the decorative cover 6 , a gap is provided between the decorative cover 6 and the guide wheel 5 .

[0127] (2) In some other examples, the guide wind wheel 5 may also rotate independently. In this case, a separate power component needs to be provided for the guide wind wheel 5 .

[0128] For example, Fig.11 and Fig.12 As shown, the ceiling fan further includes a second motor 7, and the second motor 7 is used to drive the guide wind wheel 5 to rotate.

[0129] In some examples, such as Fig.11 As shown, one end of the second stator 71 of the second motor 7 is connected to the suspension rod, and the other end is connected to the first stator 21 (that is, the suspension rod, the second stator 71 of the second motor 7, and the first stator 21 of the first motor 2 are connected in series in sequence). The second rotor 72 of the second motor 7 is connected to the guide wheel 5, and the second rotor 72 can drive the guide wheel 5 to rotate.

[0130] Since the second motor 7 can independently drive the guide wheel 5 to rotate, the control of the rotational speed of the guide wheel 5 is more flexible. The rotational speed of the guide wheel 5 can be the same as the rotational speed of the fan blade mounting component 3, or it can be different from the rotational speed of the fan blade mounting component 3. The rotational speed of the guide wheel 5 can be controlled according to actual needs.

[0131] For example, when a greater boosting effect is needed, the rotation speed of the guide wheel 5 can be controlled to be higher than the rotation speed of the fan blade mounting component 3, and when a softer boosting effect is needed, the rotation speed of the guide wheel 5 can be controlled to be lower than the rotation speed of the fan blade mounting component 3. In addition, when the guide wheel 5 is not needed for boosting, the guide wheel 5 can be controlled to stop rotating, thereby reducing the energy consumption of the ceiling fan.

[0132] It can be seen that by providing an independent power component for the guide wheel 5, the control of the guide wheel 5 can be decoupled from the control of the fan blades 4, and the user can control the rotation speed of the guide wheel 5 more flexibly according to personal needs.

[0133] In some examples, in order to improve the stability of the guide wind wheel 5, the ceiling fan further includes a bearing, and the bearing can be a rolling bearing or a sliding bearing (or called a sliding device).

[0134] Exemplarily, when the bearing is a rolling bearing, the bearing includes a fixed ring and a rotating ring. The fixed ring of the bearing is fixed to the first stator 21 or the suspension rod, and the rotating ring of the bearing is fixed to the guide wind wheel 5. Then, the bearing can support the guide wind wheel 5, making the guide wind wheel 5 more stable.

[0135] As another example, the bearing is a sliding bearing, and the sliding bearing is fixed to the first stator 21 or the suspension rod, and the guide wind wheel 5 is slidingly connected to the sliding bearing. The sliding bearing can support the guide wind wheel 5, making the guide wind wheel 5 more stable.

[0136] The present disclosure also provides a floor-standing fan, such as Figure 13-Figure 15 , comprising a support 1, a first motor 2, a fan blade mounting component 3, a fan blade 4 and a guide wheel 5. The support 1 is connected to the first stator 21 of the first motor 2, and the first rotor 22 of the first motor 2 is connected to the fan blade mounting component 3. There are multiple fan blades 4, and one end of the multiple fan blades 4 is connected to the fan blade mounting component 3. The guide wheel 5 is located on the side where the multiple fan blades 4 enter the wind, and is coaxial with the fan blade mounting component 3. The guide wheel 5 can rotate to guide the air at the first motor 2 and the fan blade mounting component 3 to the multiple fan blades 4.

[0137] Wherein, the support member 1 comprises a support rod. In some examples, such as Figure 13-Figure 15 As shown, the support member 1 includes a base and a support rod, one end of the support rod is connected to the base, and the other end of the support rod is connected to the first motor 2.

[0138] The first motor 2 is a power component for rotating the fan blade installation component 3 and the fan blade 4, and includes a first stator 21 and a first rotor 22. The first stator 21 is connected to the support rod, and the first rotor 22 can rotate relative to the first stator 21 and is used to drive the fan blade installation component 3 to rotate.

[0139] A plurality of blades 4 are fixed to the blade mounting member 3. In some examples, the plurality of blades 4 are evenly distributed along the circumference of the blade mounting member 3. The disclosed embodiment does not limit the number of blades 4. In some examples, the number of blades 4 is 4. Of course, the number of blades 4 can also be other numbers, such as 3, but is not limited thereto.

[0140] The guide wind wheel 5 can guide the air at the fan blade mounting component 3 (such as Fig.13 as shown) or the air at the first motor 21 (as shown Fig.14 and Fig.15 As shown in the figure, the air is directed to a plurality of fan blades 4, thereby increasing the air volume and air pressure of the fan without increasing the number of fan blades 4.

[0141] The floor-standing fan provided in the embodiment of the present disclosure has a guide wheel 5, which is located on the side of the fan blade 4 where the wind enters, and is coaxial with the fan blade mounting component 3. The guide wheel 5 can rotate to guide the air at the fan blade mounting component 3 or the first motor 2 to the plurality of fan blades 4. Therefore, the floor-standing fan provided in the embodiment of the present disclosure can not only drive the air around the fan blade mounting component 3 and the first motor 2, but also drive the air at the fan blade mounting component 3 and the first motor 2 through the guide wheel 5, thereby increasing the air volume and air pressure generated when the floor-standing fan rotates, so that the floor-standing fan has a higher working efficiency.

[0142] The disclosed embodiment does not limit the shape of the guide wheel 5. The specific shape of the guide wheel 5 can be referred to the above description of the guide wheel 5, which will not be repeated here.

[0143] The embodiment of the present disclosure does not limit the rotation mode of the guide wheel 5. The guide wheel 5 can rotate together with the fan blade mounting component 3 or the first rotor 22, or can rotate independently.

[0144] The following describes the configuration of the guide wind wheel 5 in the above two cases respectively:

[0145] (1) In some examples, the guide wheel 5 rotates together with the first rotor 22 or the fan blade mounting component 3 .

[0146] For example, Fig.13 As shown, the guide wheel 5 is connected to the fan blade mounting component 3. When the fan blade mounting component 3 rotates, the guide wheel 5 and the fan blade 4 rotate synchronously with the fan blade mounting component 3, and the guide wheel 5 and the fan blade 4 have the same rotation speed.

[0147] In this case, when the guide wheel 5 rotates, the air at the fan blade mounting component 3 can be directed to the multiple fan blades 4, thereby improving the efficiency of the floor-standing fan.

[0148] For example, Fig.14As shown, the guide wind wheel 5 is connected to the first rotor 22 .

[0149] like Fig.14 As shown, the guide wheel 5 is located on the side of the first motor 2 away from the fan blades 4, and is connected to the first rotor 22. When the first rotor 22 rotates, the fan blade mounting component 3, the fan blades 4, and the guide wheel 5 rotate synchronously with the first rotor 22, and the guide wheel 5 and the fan blades 4 have the same rotation speed.

[0150] In this case, when the guide wheel 5 rotates, the air at the first motor 2 can be guided to the multiple fan blades 4, thereby improving the situation where the air in the middle area of ​​the multiple fan blades 4 cannot be effectively utilized due to being blocked by the first motor 2, thereby improving the efficiency of the floor-standing fan.

[0151] (2) In some other examples, the guide wind wheel 5 may also rotate independently. In this case, a separate power component needs to be provided for the guide wind wheel 5 .

[0152] For example, Fig.15 As shown, the fan further includes a second motor 7, and the second motor 7 is used to drive the guide wind wheel 5 to rotate.

[0153] In some examples, such as Fig.15 As shown, the second stator 71 of the second motor 7 is connected to the first stator 21 of the first motor 2. The second rotor 72 of the second motor 7 is connected to the inducer wheel 5, and the second rotor 72 can drive the inducer wheel 5 to rotate.

[0154] In this case, when the guide wheel 5 rotates, the air at the first motor 2 can be guided to the multiple fan blades 4, thereby improving the situation where the air in the middle area of ​​the multiple fan blades 4 cannot be effectively utilized due to being blocked by the first motor 2, thereby improving the efficiency of the floor-standing fan.

[0155] It should be noted that Fig.14 and Fig.15 In the two forms of floor-standing fans shown, in some examples, in order to improve the stability of the guide wind wheel 5, the floor-standing fan also includes a bearing, which can be a rolling bearing or a sliding bearing (or called a sliding device).

[0156] Exemplarily, when the bearing is a rolling bearing, the bearing includes a fixed ring and a rotating ring, the fixed ring of the bearing is fixed to the first stator 21 or the second stator 71, and the rotating ring of the bearing is fixed to the guide wind wheel 5, then the bearing can support the guide wind wheel 5, making the guide wind wheel 5 more stable.

[0157] As another example, the bearing is a sliding bearing, and the sliding bearing is fixed to the first stator 21 or the second stator 71, and the guide wheel 5 is slidingly connected to the sliding bearing. Then, the sliding bearing can support the guide wheel 5, making the guide wheel 5 more stable.

[0158] It should be noted that the floor-standing fan provided in the embodiments of the present disclosure includes not only a fan placed on the ground, but also a fan placed on a desktop.

[0159] The present disclosure also provides a fan light. Figure 1 As shown, the fan and the lamp 8 are included. The lamp 8 is located on a side of the fan blade mounting component 3 away from the support 1 .

[0160] In some examples, such as Figure 1 As shown, the fan included in the fan lamp is a ceiling fan, and the lamp 8 is connected to the first stator 21 of the first motor 2.
