[0041] See also Figures 1 to 3 The present invention provides an air outlet module 100 and an air conditioner 500 including the air outlet module 100. The air outlet module 100 is installed in the air conditioner 500 to drive air flow to blow out from the inside of the air conditioner 500. The air conditioner 500 can be a floor-standing air conditioner indoor unit or a mobile air conditioner. The following mainly takes the floor-standing air conditioner indoor unit as an example for description.

[0042] See also Figures 5 to 7 In one embodiment of the air outlet module 100, the air outlet module 100 includes a mounting plate 110 and a plurality of fans 120. The mounting plate 110 is suitable for being rotatably mounted on the air outlet device; the plurality of fans 120 are mounted on the mounting plate 110, and the plurality of fans 120 are arranged around the rotation center of the mounting plate 110.

[0043] Specifically, the air outlet device should have an air outlet, which can be an air conditioner, an air machine, a fan or other equipment with an air outlet function. Here, the air conditioner is mainly used as an example for introduction. For the mounting disk 110 of the air outlet module 100, the mounting disk 110 is arranged in a circular shape, and the mounting disk 110 is provided with an air outlet 101, and the fan 120 is correspondingly installed at the air outlet 101 of the mounting disk 110. By driving the mounting disk 110 to rotate, the fan 120 can be driven to rotate in the same direction as a whole, so that the airflow blown by the fan 120 flows forward and diffuses in a spiral shape. This airflow can not only accelerate the disturbance of indoor airflow, accelerate indoor air circulation, and improve cooling or heating efficiency; but also diffuse the airflow to become softer, reduce the wind feeling, and greatly improve comfort. When the mounting disk 110 does not rotate, multiple fans blow out direct current airflow along its axial direction to achieve conventional air outlet.

[0044] The technical solution of the present invention is to install the fan 120 on the mounting plate 110 and surround the fan 120 around the rotation center of the mounting plate 110, so that after the air outlet module 100 is rotatably mounted to the air outlet 501 of the air outlet device through the mounting plate, the mounting plate 110 is driven to drive the fan 120 to rotate together, and the airflow blown out by the fan 120 is blown forward in a spiral shape. This spiral airflow can not only accelerate the disturbance of indoor airflow, accelerate indoor air circulation, and improve cooling or heating efficiency; but also diffuse the airflow to make it softer, reduce the wind feeling, and greatly improve comfort. In addition, the position where the multiple spiral airflows are formed forms a large air pressure difference with the surrounding environment. This part of the air pressure difference forces the indoor airflow to flow faster (i.e., "air suction effect"), thereby quickly disturbing the indoor air and accelerating the indoor air circulation.

[0045] See also Figure 6 and Figure 7 In one embodiment, for the type of the fan 120, the fan 120 may be an axial flow fan. The number of the fans 120 may be one, two, or more. In this case, the fans 120 are arranged in a plurality, and the plurality of fans 120 surround the circumference of the rotation center of the mounting plate 110, so that when the mounting plate 110 rotates, the plurality of fans 120 blow out a plurality of spiral airflows, and a large air pressure difference is formed between the position where the plurality of spiral airflows are formed and the surrounding environment. This part of the air pressure difference forces the indoor airflow to flow faster (i.e., "air suction"), thereby quickly disturbing the indoor air and accelerating the indoor air circulation.

[0046] As for the arrangement position of the fan 120, multiple fans 120 can be distributed in the same circumferential area, that is, the distances from the axes of the multiple fans 120 to the rotation center of the mounting disk 110 are equal, so that the multiple fans 120 can be evenly arranged around the rotation center of the mounting disk 110. When the mounting disk 110 rotates, the multiple fans 120 evenly supply air to the circumference of the mounting disk 110.

[0047] Of course, in its embodiment, the multiple fans 120 can also be distributed in different circumferential areas, that is, the distances from the axes of the multiple fans 120 to the rotation center of the mounting disk 110 are not equal. In this way, the multiple fans 120 can disturb the indoor air at different distances around the mounting disk 110, and the frequencies of the spiral airflows are different, thus avoiding the noise generated by the resonance of the spiral airflows.

[0048] In one embodiment, the fan 120 includes a wind tube 121, an axial flow wind wheel 122 and a wind wheel motor 123. The wind tube 121 is connected to the mounting plate 110; the axial flow wind wheel 122 is arranged in the wind tube 121; the wind wheel motor 123 is connected to the axial flow wind wheel 122 to drive the axial flow wind wheel 122 to rotate and blow air. There can be one or two axial flow wind wheels 122.

[0049] Specifically, the fan 120 includes two axial flow wind wheels 122, which are arranged in the wind tube 121 along the axial direction of the wind tube 121, and the wind wheel motor 123 is arranged between the two axial flow wind wheels 122, and the wind wheel motor 123 has two motor shafts extending in opposite directions, and the two motor shafts are respectively connected to the two axial flow wind wheels 122. The two axial flow wind wheels 122 jointly drive the airflow to flow, thereby effectively increasing the air output. And the two axial flow wind wheels 122 are driven by only one motor, which can reduce the number of motors, thereby reducing the occupied space, so that the volume of the fan 120 is smaller.

[0050] See also Figures 6 to 8 In one embodiment, the air outlet module 100 further includes a first driving device 200 suitable for installation on the air outlet device, and the first driving device 200 is connected to the mounting disk 110 to drive the mounting disk 110 to rotate relative to the air outlet 502. When the air outlet module 100 is installed on the air outlet device, the first driving device 200 is connected to the air outlet device. It should be noted that in other embodiments, the mounting disk 110 can also be driven by the driving source 310 on the air outlet device, and the air outlet module 100 itself does not need to be equipped with the first driving device 200, which is conducive to modularizing the air outlet module 100.

[0051] Regarding the structural composition of the first driving device 200, in one embodiment, the first driving device 200 includes a first motor 210 and a rotating wheel 220; wherein the rotating wheel 220 is connected to the mounting disk 110; the first motor 210 is connected to the rotating wheel 220 to drive the rotating wheel 220 to drive the mounting disk 110 to rotate.

[0052] Optionally, the rotating wheel 220 may be a gear or a friction wheel. Specifically, the rotating wheel 220 is a friction wheel, and a friction groove is provided on the peripheral side of the rotating wheel 220; the mounting plate 110 has a plate body 111 for mounting the fan 120, and friction ribs 112 provided along the peripheral edge of the plate body 111, and the friction ribs 112 are installed in the friction groove of the rotating wheel 220.

[0053] Since the air outlet module 100 is usually located in a position that can be touched by the user, the installation disk 110 is driven to rotate by means of a friction wheel, so that when the installation disk 110 is accidentally touched or stuck by the user, relative sliding occurs between the installation disk 110 and the friction wheel, which is beneficial to ensure the safety of the installation disk 110. The friction groove can effectively ensure the stability of the installation of the installation disk 110 and prevent the installation disk 110 from slipping off the friction wheel. Of course, the rotating wheel 220 of this embodiment is not limited to the above technical solution. In other embodiments, the rotating wheel 220 can also be a gear, and the outer edge of the installation disk 110 forms a driven wheel. The rotating wheel 220 meshes with the outer edge of the installation disk 110, which has the advantage of stable transmission effect.

[0054] Further, there are multiple rotating wheels 220, and the multiple rotating wheels 220 are arranged at intervals along the circumference of the mounting disk 110, and one of the rotating wheels 220 is connected to the first motor 210. Among them, the multiple rotating wheels 220 cooperate to define the running track of the mounting disk 110, and the multiple rotating wheels 220 work together to increase the friction force of the rotating wheel on the mounting disk, which is conducive to driving the mounting disk 110 to operate stably. Of course, the driving method of the mounting disk 110 is not limited to this. In other embodiments, the driving shaft of the first motor 210 can also be directly connected to the rotation center of the mounting disk 110 to directly drive the mounting disk 110 to rotate.

[0055] Optionally, at least one of the multiple wheels 220 is located at the top of the mounting disk 110, and the first motor 210 is connected to the wheel 220 located at the top of the mounting disk 110. This can avoid the gravity of the mounting disk 110 from acting on the wheel 220 located at the top thereof, reduce the load force of the first motor 210, and the first motor 210 can drive the mounting disk 110 to rotate using a smaller driving force.

[0056] See also Figure 6 and Figure 7 The air outlet module 100 further includes a mounting plate 511 , which is provided with an air outlet 502 for mounting the mounting plate 110 , and the mounting plate 511 is provided with a receiving groove 503 for mounting the rotating wheel 220 around the air outlet 502 .

[0057] Specifically, the mounting plate 511 can be a part of the housing of the air outlet device, or a separate component additionally configured in the housing. Specifically, the mounting plate 511 is a part of the housing 510 of the air outlet device, and more specifically, the mounting plate 511 is the front shell 511 of the housing 510, and the air outlet on the mounting plate 511 is the air outlet (502). By providing a plurality of accommodating grooves 503 around the air outlet of the mounting plate 511, a plurality of rotating wheels 220 can be installed in the corresponding accommodating grooves 503 to separate the rotating wheels 220 from the surrounding components, so as to prevent the rotating wheels 220 from interfering with the surrounding components during rotation.

[0058] See also Figure 7 and Figure 8 In one embodiment, the axes of two adjacent fans 120 are respectively connected to the rotation center of the mounting disk 110, forming two first radial lines; among the multiple impellers 220 for driving the mounting disk 110 to rotate, the axes of any two adjacent impellers 220 are respectively connected to the rotation center of the mounting disk 110, forming two second radial lines; wherein the central angle between the two first radial lines is equal to the central angle between the two second radial lines.

[0059] Specifically, the number of the rotors 220 is the same as the number of the fans 120; the multiple rotors 220 are evenly and spacedly arranged along the periphery of the mounting disk 110; the multiple fans 120 are evenly and spacedly arranged along the same circumferential area between the periphery and the rotation center of the mounting disk 110. By defining the center angle between the two second radial lines to be equal to the center angle between the second radial lines, it can be ensured that at any time, the center of gravity of the whole composed of the multiple fans 120 coincides with the center of force applied by the multiple rotors 220 to the mounting disk 110, so that the mounting disk 110 rotates stably. It should be noted that the first radial line and the second radial line are both virtual lines assumed for the convenience of description.

[0060] Based on any of the above embodiments, the mounting plate 110 is provided with an air supply port 101, and the fan 120 is installed in the air supply port 101. The air supply port 101 may be an annular air supply port arranged in an annular shape and surrounding the rotation center of the mounting plate, and a plurality of fans 120 are arranged in an annular shape along the annular air supply port, so that the plurality of fans 120 surround the rotation center of the mounting plate 110. Alternatively, the air supply port 101 is provided in plurality, and the plurality of air supply ports 101 are all provided in a circular shape, and the plurality of air supply ports 101 surround the rotation center of the mounting plate 110, and a fan 120 is installed corresponding to each air supply port 101. Specifically, the mounting plate 110 is provided with a plurality of air supply ports 101, and a fan 120 is installed corresponding to each air supply port 101.

[0061] Furthermore, to facilitate the installation of the fan 120, a mounting ring 113 is provided on the periphery of the air supply port 101; the air outlet module 100 also includes a mounting sleeve 130 mounted on the outside of the fan 120, and the mounting sleeve 130 is connected and fixed to the mounting ring 113, thereby limiting the fan 120 on the mounting plate 110.

[0062] It is considered that the thickness of the mounting plate 110 is usually designed to be small in order to reduce its own weight. However, as a result, the strength of the position where the air outlet 101 is provided on the mounting plate 110 is small and may not be sufficient to support the fan 120. To solve this problem, a plurality of reinforcing ribs 114 are optionally provided on the inner surface of the mounting plate 110 between two adjacent air outlets 101, and some of the reinforcing ribs 114 are connected to the mounting collar 113.

[0063] Specifically, a plurality of reinforcing ribs 114 are arranged in a cross-pattern, wherein some of the reinforcing ribs 114 extending in the transverse direction or the reinforcing ribs 114 extending in the longitudinal direction are connected to the outer wall surface of the mounting ring 113 to increase the strength of the mounting ring 113, so that the fan 120 installed on the mounting ring 113 is not easy to crush the mounting plate 110, thereby improving the stability of the installation of the fan 120.

[0064] See also Figures 7 to 9Based on any of the above embodiments, the air outlet module 100 also includes a support frame 140 covering the windward surface of the mounting plate 110, the support frame 140 includes a support seat 141 opposite to the rotation center of the mounting plate 110, and a plurality of support feet 142 extending from the circumference of the support seat 141, and the plurality of support feet 142 are connected and fixed to the periphery of the mounting plate 110.

[0065] Specifically, the mounting plate 110 is provided with a mounting platform 103 at a position on its periphery corresponding to the area between two adjacent fans 120 ; a fixing portion 145 is extended laterally from the bottom of the supporting foot 142 , and the fixing portion 145 is connected and fixed to the mounting platform 103 .

[0066] See also Figure 5 , Figure 7 and Fig.10 Based on any of the above embodiments, the air outlet module 100 further includes a second driving device 300, the connecting rod second driving device 300 is connected to the fan 120, and the connecting rod second driving device 300 is used to drive the fan 120 to rotate and adjust the blowing direction of the fan 120. The second driving device 300 drives the fan 120 to rotate to adjust the blowing direction, so that the air outlet module 100 has a high degree of automation and convenient angle adjustment. Of course, in other embodiments, the fan 120 can also adjust its rotation angle manually.

[0067] By driving the fan 120 to rotate as a whole through the second driving device 300, the angle between the axis direction of the fan 120 and the rotation axis of the mounting plate 110 can be adjusted, thereby changing the blowing direction of the fan 120. For example, when the fan 120 rotates to the angle between its axis direction and the rotation axis of the mounting plate 110 equals 0° (i.e., the axis direction of the fan 120 is parallel to the rotation axis of the mounting plate 110), the fan 120 blows directly to the front side of the air conditioner 500; when the fan 120 rotates to the angle between its axis direction and the rotation axis of the mounting plate 110 is not 0°, the fan 120 blows diffusely around the air conditioner 500 (such as blowing to the left, blowing to the right, blowing upwards, or blowing downwards). It should be noted that the axis direction of the fan 120 itself refers to the axial direction of the axial flow impeller 122 of the fan 120.

[0068] The blowing angles of the multiple fans 120 on the mounting plate 110 may be different, or they may blow air in the same direction. When the multiple fans 120 have the same direction, the multiple fans 120 blow air in the same direction, thereby realizing concentrated air outlet; when the multiple fans 120 have different directions, the multiple fans 120 blow air in different directions, thereby realizing outward-expanding air outlet.

[0069] See also Figure 7 and Fig.10For the connecting rod second driving device 300, optionally, the connecting rod second driving device 300 includes a driving source 310, a transmission member 315 and a connecting rod 330. The transmission member 315 is connected to the driving source 310 so as to be driven by the driving source 310 to move along the axis direction of the mounting plate 110; one end of the connecting rod 330 is hinged to the transmission member 315, and the other end of the connecting rod 330 is hinged to the fan 120.

[0070] Specifically, the connecting rod 330 is hinged to the outer periphery of the wind tube 121 of the fan 120; when the transmission member 315 moves along the axial direction of the mounting plate 110, the fan 120 can be driven to rotate through the connecting rod 330, thereby changing the angle of the fan 120. The angle change of multiple fans 120 can be controlled simultaneously by a transmission member 315, which is conducive to improving the adjustment efficiency. Of course, in other embodiments, each fan 120 may also correspond to a driving device separately, which is conducive to accurately adjusting the rotation angle of each fan 120 and having more air outlet modes.

[0071] See also Figure 7 , Fig.10 and Fig.11 Further, the driving source 310 includes a worm 311, a first gear 312, a second gear 313 and a second motor 314. The worm 311 extends along the rotation axis of the mounting plate 110; the first gear 312 is passed through and fixed to one end of the worm 311; the second gear 313 is meshed with the first gear 312; the second motor 314 is connected to the second gear 313; the transmission member 315 is a worm wheel 315 sleeved on the worm 311, and the worm wheel 315 is threadedly connected to the worm 311.

[0072] When the connecting rod second driving device 300 is working, the second motor 314 drives the second gear 313 to drive the first gear 312 to rotate, and the first gear 312 drives the worm 311 to rotate. Since the worm 311 is threadedly connected to the worm wheel 315, the worm wheel 315 will move along the extension direction of the worm 311 as the worm 311 rotates, thereby pulling the fan 120 to rotate through the connecting rod 330.

[0073] The cooperation between the worm 311 and the worm wheel 315 has the characteristic of high position adjustment accuracy of the worm wheel 315, and when the worm 311 stops rotating, the positioning effect of the worm wheel 315 is good, and the fan 120 can maintain a stable angle. Of course, the air outlet module 100 described in this embodiment is not limited to the above technical solution. In other embodiments, the driving source 310 can also be a cylinder, and the cylinder drives the transmission member 315 to move; or the driving source 310 is a hydraulic driving member, and the hydraulic start key drives the transmission member 315 to move, which has the advantage of simple structure.

[0074] See also Figures 7 to 10Further, the support frame 140 is provided with a first mounting groove 143 , and the mounting plate 110 is provided with a second mounting groove 102 ; one end of the worm 311 is rotatably mounted in the first mounting groove 143 , and one end of the worm 311 is rotatably mounted in the second mounting groove 102 .

[0075] Optionally, the air outlet module 100 further includes a first bearing 315 and a second bearing 316 disposed at both ends of the worm 311; one end of the worm 311 is rotatably mounted in the first mounting groove 143 of the support frame 140 through the first bearing 315; the other end of the worm 311 is rotatably mounted in the second mounting groove 102 of the mounting plate 110 through the second bearing 316. The first gear 312 of the driving source 310 is accommodated in the first mounting groove 143.

[0076] Optionally, the support frame 140 is further provided with a mounting box 144, and the second motor 314 and the second gear 313 are disposed in the mounting box 144. More specifically, the mounting box 144 is formed between two adjacent supporting legs 142, and the mounting box 144 is connected to the supporting seat 141. The mounting box 144 is located on the support frame 140, which is not only convenient for installing the second motor 314, but also conducive to the assembly between the second motor 314 and the worm 311.

[0077] See also Figure 7 and Figure 8 In one embodiment, the air outlet module 100 further includes a mounting sleeve 130, the mounting sleeve 130 is sleeved with the fan 120, and the fan 120 is mounted at the air outlet 101 of the mounting plate 110 through the mounting sleeve 130. Optionally, the fan 120 is movably connected to the mounting sleeve 130. Specifically, the mounting sleeve 130 is connected and fixed to the mounting collar 113 at the air outlet 101, such as by screws or buckle structures.

[0078] Furthermore, the inner surface of the mounting sleeve 130 and the outer surface of the wind tube 121 of the fan 120 are set as a spherical zone ( Figure 4 131 is represented as a spherical band) so that the outer surface of the wind tube 121 fits with the inner surface of the mounting sleeve 130 and can move relatively, so that the wind tube 121 of the fan 120 can rotate at any angle in the mounting sleeve 130, thereby adjusting the blowing angle. It should be noted that the spherical band refers to the part of the spherical surface obtained by intercepting two mutually parallel planes and located between the two planes.

[0079] The above-mentioned connection mode between the mounting sleeve 130 and the wind tube 121 can reduce the gap between the mounting sleeve 130 and the wind tube 121, reduce the amount of air leaking from the gap, and help to ensure the air output of the fan 120. More specifically, the inner diameter of the mounting sleeve 130 increases first and then decreases along the air outlet direction of the fan 120, so the wind tube 121 can be stably arranged in the mounting sleeve 130 without other connection structures. The fan 120 is universally connected to the mounting plate 110, so that the fan 120 can rotate along the circumferential direction of the mounting plate 110, and can also rotate along the circumferential direction of the circumferential surface perpendicular to and concentric with the mounting plate 110.

[0080] Of course, the universal connection structure between the mounting disk 110 and the fan 120 described in this embodiment is not limited to the above-mentioned technical solution. In other embodiments, the mounting disk 110 may have a protrusion, and a spherical joint is provided at the end of the protrusion, and the wind cylinder 121 of the fan 120 is provided with a spherical groove adapted to the spherical joint, and the spherical joint is arranged in the spherical groove, thereby realizing the universal connection between the fan 120 and the mounting disk 110; it can also be that the wind cylinder 121 and the mounting sleeve 130 are rotatably connected through a rotating shaft, and the rotating shaft extends radially along the mounting hole of the mounting disk 110, and the rotating shaft and the axis of the mounting disk 110 and the circular mounting hole are perpendicular to each other.

[0081] See also Figure 7 , Fig.10 and Fig.12 Based on any of the above embodiments, the air outlet module 100 also includes a conductor 400 and a first brush assembly; wherein the conductor 400 includes two coaxially arranged conductive cores 410, and the two conductive cores 410 are connected to the fan 120; the first brush assembly includes two first brushes 610 connected to a power supply, and the two first brushes 610 are respectively suitable for electrically contacting the two conductive cores 410 of the conductor 400.

[0082] See also Fig.12 and Fig.13 When the air outlet module is installed on the air outlet device, the first brush assembly is fixed on the component of the air outlet device located outside the air outlet module, and the first brush assembly is electrically connected to the power supply. When the mounting plate 110 rotates, the conductor 400 is driven by the mounting plate 110 to rotate together, and the conductor 400 rotates relative to the first brush assembly. The two conductive cores 410 of the conductor 400 respectively maintain electrical contact with the two first brushes 610 of the first brush assembly to conduct current between the rotating conductor 400 and the power supply stationary relative to the conductor 400. There is no power line between the conductor 400 and the first brush 610, so when the conductor 400 rotates relative to the power supply, the power line will not be entangled or broken, so that the fan 120 and the power supply remain connected, thereby ensuring that the fan 120 can work stably.

[0083] It should be noted that the two conductive cores 410 of the conductor are insulated and separated, one conductive core 410 can be used as a ground line, and the other conductive core 410 can be used as a live line. Optionally, the conductive core 410 includes a conductor 411 and an insulating layer 412 included outside the conductor 411.

[0084] There are also many ways to design the way the first brush 610 makes electrical contact with the conductive core 410. For example, the first brush 610 can be designed as an elastic contact piece, which elastically presses against the end surface of the conductive core 410, so that the elastic contact piece can maintain electrical contact with the conductive core 410 during the rotation of the conductive core 410. For another example, the first brush 610 is designed as an elastic conductive clip, which is clamped on the conductive core 410, so that the conductive core 410 is confined in the clamping groove of the elastic conductive clip to make rotational movement, and maintains electrical contact with the elastic conductive clip during this process. For another example, the first brush 610 can be designed as a conductive ring, and the conductive ring is looped around the outer periphery of the end of the conductive core 410, so that the conductive core 410 is confined in the conductive ring to make rotational movement, and maintains electrical contact with the conductive ring during this process.

[0085] See also Fig.13 and Fig.14 In one embodiment, the electrical contact between the first brush 610 and the conductive core 410 adopts the first design method mentioned above, that is, the first brush 610 can be designed as a conductive ring, and the conductive ring is looped around the outer circumference of the end of the conductive core 410. Specifically, the ends of the two conductive cores 410 away from the mounting plate 110 are configured with a first slip ring 420; the two first brushes 610 are arranged in a ring shape, and each first brush 610 is correspondingly looped on the first slip ring 420 of a conductive core 410. During the rotation of the conductor 400, the first slip ring 420 is limited to rotate on the inner circumference of the first brush 610, and the first slip ring 420 is not easy to deviate from the rotation path, thereby ensuring that the first slip ring 420 and the first brush 610 maintain electrical contact.

[0086] Furthermore, a first annular groove is provided on the inner periphery of the first brush 610, and the first brush 610 can rotatably cooperate with the first slip ring 420 of the conductive core 410 through the first annular groove. In other words, the first slip ring 420 of the conductive core 410 is limited to rotate in the first annular groove of the first brush 610, and during the rotation process, the periphery of the first slip ring 420 continuously slides in contact with the inner wall surface of the first annular groove, thereby effectively preventing the first slip ring 420 from being loosened from the first brush 610, and improving the stability of the assembly of the two.

[0087] Please continue reading Figures 8 to 10It is taken into consideration that relative rotational movement may occur between the conductor 400 and the mounting disk 110. For example, when the conductor 400 is rotatably mounted on the mounting disk 110, or the connection between the conductor 400 and the mounting disk 110 is loose, the conductor 400 may not rotate with the mounting disk 110. In this case, the conductor 400 also rotates relative to the mounting disk 110, and winding may occur between the conductor 400 and the fan 120 fixed on the mounting disk 110.

[0088] In view of this, in order to reduce the occurrence of this situation, optionally, the air outlet module 100 also includes a second brush assembly, which includes two second brushes 620 fixed to the mounting plate 110 and connected to the fan 120, and the two second brushes 620 are respectively suitable for electrical contact with the two conductive cores 410 of the conductor 400.

[0089] Specifically, when the conductor 400 rotates relative to the mounting plate 110, the conductor 400 rotates relative to the second brush 620, while the second brush 620 and the fan 120 are both stationary relative to the mounting plate 110, and the wire of the fan 120 between the second brush 620 and the fan 120 does not rotate and therefore does not get tangled; during this process, the conductor 400 always maintains electrical contact with the second brush 620 to conduct current between the rotating conductor 400 and the fan 120 that is stationary relative to the conductor 400. Since the conductor 400 and the second brush 620 are electrically connected and there is no wire, the wire of the fan 120 will not get tangled or broken, so that the fan 120 and the power source remain connected, thereby ensuring that the fan 120 can work stably.

[0090] See also Fig.13 and Fig.14 For the electrical contact between the second brush 620 and the conductive core 410, please refer to the design of the first brush 610 and the conductive core 410, which will not be described here. Optionally, the ends of the two conductive cores 410 away from the mounting plate 110 are configured with a second slip ring 430; the two second brushes 620 are arranged in a ring shape, and each second brush 620 is correspondingly sleeved on the second slip ring 430 of a conductive core 410. During the rotation of the conductor 400, the second slip ring 430 is limited to rotate on the inner circumference of the second brush 620, and the second slip ring 430 is not easy to deviate from the rotation path, thereby ensuring that the second slip ring 430 and the second brush 620 maintain electrical contact.

[0091] Furthermore, a second annular groove is provided on the inner periphery of the second brush 620, and the second brush 620 can rotatably cooperate with the second slip ring 430 of the conductive core 410 through the second annular groove. In other words, the second slip ring 430 of the conductive core 410 is limited to rotate in the second annular groove of the second brush 620, and during the rotation process, the periphery of the second slip ring 430 continuously slides in contact with the inner wall surface of the second annular groove, thereby effectively preventing the second slip ring 430 from being loosened from the second brush 620, and improving the stability of the assembly of the two.
